7,700 | Bamberg | The Schlenkerla, one of Bamberg's famous breweries and taverns. Alte Hofhaltung (Old Palace). Bamberg is a town in Bavaria, Germany. It is located in Upper Franconia on the river Regnitz, close to its confluence with the river Main. Bamberg is one of the few cities in Germany that was not destroyed by World War II bombings because of a nearby Artillery Factory that prevented planes from getting near to Bamberg. Bamberg is home to nearly 7,000 foreign nationals, including over 4,100 members of the United States Army and their dependents. The name Bamberg is supposed to have its origin in the House of Babenberg. History During the post-Roman centuries of Germanic migration and settlement, the region afterwards included in the Diocese of Bamberg was inhabited for the most part by Slavs. The town, first mentioned in 902, grew up by the castle (Babenberch) which gave its name to the Babenberg family. On their extinction it passed to the Saxon house. The area was Christianized chiefly by the monks of the Benedictine Fulda Abbey, and the land was under the spiritual authority of the Diocese of Würzburg. In 1007, Henry II, King of the Romans, made Bamberg a family inheritance, the seat of a separate diocese. The emperor's purpose in this was to make the Diocese of Würzburg less unwieldy in size and to give Christianity a firmer footing in the districts of Franconia, east of Bamberg. In 1008, after long negotiations with the Bishops of Würzburg and Eichstätt, who were to cede portions of their dioceses, the boundaries of the new diocese were defined, and Pope John XVIII granted the papal confirmation in the same year. Henry II ordered the building of a new cathedral, which was consecrated May 6, 1012. The church was enriched with gifts from the pope, and Henry II had it dedicated in honor of him. In 1017 Henry II also founded Michaelsberg Abbey on the Michaelsberg ("Mount St. Michael"), near Bamberg, a Benedictine abbey for the training of the clergy. The emperor and his wife Cunigunde gave large temporal possessions to the new diocese, and it received many privileges out of which grew the secular power of the bishop. Pope Benedict VIII during his visit to Bamberg (1020) placed the diocese in direct dependence on the Holy See. For a short time Bamberg was the centre of the Holy Roman Empire. Henry and Cunigunde were both buried in the cathedral. From the middle of the 13th century onward the bishops were princes of the Empire and ruled Bamberg, overseeing the construction of monumental buildings. In 1248 and 1260 the see obtained large portions of the estates of the Counts of Meran, partly through purchase and partly through the appropriation of extinguished fiefs. The old Bishopric of Bamberg was composed of an unbroken territory extending from Schlüsselfeld in a northeasterly direction to the Franconian Forest, and possessed in addition estates in the Duchies of Carinthia and Salzburg, in the Nordgau (the present Upper Palatinate), in Thuringia, and on the Danube. By the changes resulting from the Reformation, the territory of this see was reduced nearly one half in extent. The witch trials of the 17th century claimed hundreds of victims, as they did in England, in Bamberg and reached a climax between 1626 and 1631 under the rule of Prince-Bishop Johann Georg II Fuchs von Dornheim. The famous Drudenhaus (witch prison), built in 1627, is no longer standing today; however, detailed accounts of some cases, like that of Johannes Junius, remain. In 1647, the University of Bamberg was founded as Academia Bambergensis. Bambrzy (Ger. Posen Bambergers) – German Poles are descendants of settlers from the area near Bamberg, who settled in villages around Posen in the years 1719 –1753. In 1759, the possessions and jurisdictions of the diocese situated in Austria were sold to that state. When the secularization of church lands took place (1802) the diocese covered and had a population of 207,000. Bamberg thus lost its independence in 1802, becoming part of Bavaria in 1803. Bamberg was first connected to the German rail system in 1844, which has been an important part of its infrastructure ever since. After a communist uprising took control over Bavaria in the years following World War I, the state government fled to Bamberg and stayed there for almost two years before the Bavarian capital of Munich was retaken by Freikorps units (see Weimar Republic). The first republican constitution of Bavaria was passed in Bamberg, becoming known as the Bamberger Verfassung (Bamberg Constitution). In February 1926 Bamberg served as the venue for the famous Bamberg Conference, convened by Adolf Hitler in his attempt to foster unity and to stifle dissent within the young NSDAP. Bamberg was chosen for its location in Upper Franconia, reasonably close to the residences of the members of the dissident northern Nazi faction but still within Bavaria. See generally See also In 1973, the town celebrated the 1000th anniversary of its founding. Historic population YearPopulation181817,000188531,521190545,308 Historic beer Bamberg is known for Rauchbier (or smoked beer in English). The most famous is Schlenkerla's Aecht Schlenkerla Rauchbier from the Heller brewery; it can be enjoyed at the Schlenkerla tavern on the Dominikaner Strasse in the Old Town. Bamberg is currently (2005) home to nine traditional breweries (Brauerei Fässla, Brauerei Greifenklau, Brauerei Heller-Trum (Schlenkerla), Brauerei Kaiserdom, Keesmann Bräu, Klosterbräu, Mahrs Bräu, Maisel Bräu and Brauerei Spezial) and one modern brewpub (Ambräusianum) Ambräusianum, Bamberg —an unusually high number for a city of 70,000. Geography Bamberg is located in Franconia, north of Nuremberg by railway and east of Würzburg, also by rail. It is situated on the Regnitz river, before it flows into the Main river. Its geography is shaped by the Regnitz and by the foothills of the Steigerwald, part of the German uplands. From northeast to southwest, the town is divided into first the Regnitz plain, then one large and several small islands formed by two arms of the Regnitz (Inselstadt), and finally the part of town on the hills, the "Hill Town" (Bergstadt). Bamberg extends over seven hills, each crowned by a beautiful church. This has led to Bamberg being called the "Franconian Rome" — although a running joke among Bamberg's tour guides is to refer to Rome instead as the "Italian Bamberg". Sights The Old Town of Bamberg is listed as a UNESCO World Heritage, primarily because of its authentic medieval appearance. The city established a documentation centre in 2005 to support World Heritage activities. Some of the main sights are: Cathedral (1237), with the tombs of emperor Henry II and Pope Clement II Alte Hofhaltung, residence of the bishops in the 16th and 17th centuries Neue Residenz, residence of the bishops after the 17th century Old Town Hall (1386), built in the middle of the Regnitz River, accessible by two bridges Klein-Venedig ("Little Venice"), a colony of picturesque fishermen's houses from the 19th century along one side of the river Regnitz. Michaelsberg Abbey, built in the 12th century on one of Bamberg's "Seven Hills" Altenburg, castle, former residence of the bishops Cathedral The Bamberger Reiter. The cathedral is a late Romanesque building with four grand towers. It was founded in 1004 by the emperor Henry II, finished in 1012 and consecrated on May 6, 1012. It was later partially destroyed by fire in 1081. The new cathedral, built by Saint Otto of Bamberg, was consecrated in 1111 and in the 13th century received its present late-Romanesque form. The cathedral is long, broad, high, and the four towers are each about high. Of its many historic works of art may be mentioned the magnificent marble tomb of the founder and his wife, considered the masterpiece of the sculptor Tilman Riemenschneider, and carved between 1499 and 1513. Another treasure of the cathedral is an equestrian statue known as the Bamberg Horseman (). This statue, possibly belonging to the emperor Conrad III, most likely dates to approximately 1200. The statue also serves as a symbol of the city. Neue Residenz The Neue Residenz (New Palace) (1698-1704) was initially occupied by the prince-bishops, and from 1864 to 1867 by the deposed King Otto of Greece. The magnificent Rosengarten (Rose Garden) offers excellent views of the city. Bamberg Altenburg The Altenburg is located at the highest of Bamberg's seven hills. It was mentioned for the first time in 902 BCE. Between 1251 and 1553 it was the residence of Bamberg's bishops. Destroyed in 1553 by Albert Alcibiades, Margrave of Brandenburg-Kulmbach, it was used, after scanty repairs, only as a prison, and increasingly decayed. In 1801 doctor A. F. Marcus bought the castle and completely repaired it. His friend, the famous German writer E.T.A. Hoffmann, who was very impressed by the building, lived there for a while. The next owner, Anton von Greifenstein, founded in 1818 an association to save the castle. This society still maintains the whole property today. The Altenburg serves as a high-class restaurant and has a beautiful view. Other sights Michaelsberg Abbey Other noteworthy churches are the Jakobskirche, an 11th-century Romanesque basilica; the St. Martinskirche; the Marienkirche or Obere Pfarrkirche (1320-1387), which has now been restored to its original pure Gothic style. The Michaelskirche, 12th-century Romanesque (restored), on the Michaelsberg, was formerly the church of the Benedictine Michaelsberg Abbey secularized in 1803 and now contains the Bürgerspital, or almshouse, and the museum and municipal art collections. Of the bridges connecting the sections of the lower town, a very interesting one is the Obere Brücke, completed in 1455. Halfway across this, on an island, is the Rathaus or City Hall (rebuilt 1744-1756). The royal lyceum, formerly a Jesuit college, contains notable collections and the royal library of over 300,000 volumes. The picturesque Old Palace (Alte Hofhaltung) was built in 1591 on the site of an old residence of the counts of Babenberg. Noteworthy among the monuments of the town is the Maximilian fountain (1880), with statues of Maximilian I of Bavaria, the emperor Henry II and his wife, Conrad III and Saint Otto, bishop of Bamberg. Education The University of Bamberg, named Otto-Friedrich University, offers higher education in the areas of social science, business studies and the humanities, and is attended by more than 9300 students. Bamberg is also home to eight secondary schools called Gymnasien: Clavius-Gymnasium Dientzenhofer-Gymnasium Eichendorff-Gymnasium E.T.A.-Hoffmann-Gymnasium Franz-Ludwig-Gymnasium Kaiser-Heinrich-Gymnasium Maria-Ward-Gymnasium Theresianum There are also numerous other institutes for primary, secondary, technical, vocational and adult education. Infrastructure Railway The InterCityExpress main line #28 (Munich - Nuremberg - Leipzig - Berlin / Hamburg) runs through Bamberg. To Munich the train journey takes about two hours. To Berlin it takes about four hours as of 2007; but construction of a new, shorter and faster connection through the Thuringian mountains has been underway for some years. East-west connections are poorer. Bamberg is connected to other towns in eastern Upper Franconia such as Bayreuth, Coburg, and Kronach, with usually at least an hourly regional service. Connections to the west are hourly regional trains to Würzburg, which is fully connected to the ICE network. Tourists arriving at Frankfurt International Airport will have to change trains in Würzburg to get to Bamberg or take a detour via Nuremberg. Motorways Bamberg is not near any of the major (i.e. single-digit) Autobahns. But it is nevertheless well connected to the network: the A70 from Schweinfurt (connecting to the A7 there) to Bayreuth (connecting to the A9) runs along the northern edge of the town. The A73 on the eastern side of town connects Bamberg to Nuremberg (connecting to the A9) and Thuringia, ending at Suhl. Water transport The Rhine-Main-Danube Canal begins near Bamberg. With its completion in 1992, uninterrupted water transport was made possible between the North Sea and the Black Sea. Local transport Local transport within Bamberg relies exclusively on buses. More than 20 lines connect the outlying quarters and some villages in the vicinity to the Central Bus Station. In addition, there are several "Night Lines" (the last of these, though, tend to run around midnight) and some Park and Ride lines from parking lots on the periphery to the town centre. A short-lived tram system existed in the 1920s. Politics Bamberg is an independent city. Its town council (Stadtrat) and its Lord Mayor (Oberbürgermeister) are elected every six years, though not in the same year. Thus, the last municipal election for the town council was in 2008, for the Lord Mayor in 2006. As of March 2008, the 44 member-town-council comprises 15 CSU councillors, 10 SPD councillors, 7 Green councillors, 5 councillors of the Bamberger Bürger-Block and 3 of the Freie Wähler (Free Voters), both local political movements. These five parties achieved the number of councillors necessary to form a caucus. In addition, there are 2 councillors of the Bamberger Realisten and one of the FDP and the far-right Republicans (Germany), making them ineligible for caucus status. This is the result of the municipal elections of 2 March 2008.

7,701 | Diene | Dienes or diolefins are hydrocarbons which contain two double bonds. Dienes are intermediate between alkenes and polyenes. Classes Dienes can be divided into three classes: Unconjugated dienes have the double bonds separated by two or more single bonds. Conjugated dienes have conjugated double bonds separated by one single bond. They are also the most stable. Cumulated dienes have the double bonds sharing a common atom as in a group of compounds called allenes. Heterodienes have one or more of the unsaturated carbon atoms replaced with a heteroatom. +Classes of Dienes1,5-Cyclooctadiene, an unconjugated diene. Notice that each double bond is two carbons away from the other.Isoprene, also known as 2-methyl-1,3-butadiene, is one of the simplest conjugated dienes.Propan-1,2-diene, also known as allene, is the simplest cumulated diene. In organic chemistry a conjugated diene is also a functional group, with a general formula of CnH2n-2. A classic organic reaction for the synthesis of dienes is the Whiting reaction. 1,3-butadiene undergoes 1,2-addition and 1,4-addition. Reactions with dienes The 1,3 configuration of double bonds found in 1,3-butadiene (conjugated double bonds) make these types of dienes capable of participating in more reaction types than is the case for molecules with either just a single alkene functional group or with multiple, but non-alternating, alkene groups. One possible reaction for such dienes is the Diels-Alder reaction for example Danishefsky’s diene.

7,702 | Hilbert's_basis_theorem | In mathematics, Hilbert's basis theorem states that every ideal in the ring of multivariate polynomials over a field is finitely generated. This can be translated into algebraic geometry as follows: every algebraic set over a field can be described as the set of common roots of finitely many polynomial equations. The theorem is named for the German mathematician David Hilbert who first proved it in 1888. Hilbert produced an innovative proof by contradiction using mathematical induction; his method does not give an algorithm to produce the finitely many basis polynomials for a given ideal: it only shows that they must exist. One can determine basis polynomials using the method of Gröbner bases. Proof The following more general statement will be proved: if R is a left (respectively right) Noetherian ring then the polynomial ring R[X] is also a left (respectively right) Noetherian ring. Let I be an ideal in R[X] and assume for a contradiction that I is not finitely generated. Inductively construct a sequence f1, f2, ... of elements of I such that fi+1 has minimal degree in I \ Ji, where Ji is the ideal generated by f1, ..., fi. Let ai be the leading coefficient of fi and let J be the ideal of R generated by a1, a2, ... Since R is Noetherian there exists an integer N such that J is generated by a1, ..., aN, so in particular aN+1 = u1a1 + ... + uNaN for some u1, ..., uN in R. Now consider g = u1f1xn1 + ... + uNfNxnN where ni = deg fN+1 − deg fi. Because deg g = deg fN+1 and the leading coefficients of g and fN+1 agree, the difference fN+1 − g has degree strictly less than the degree of fN+1, contradicting the choice of fN+1. Therefore I is finitely generated, and the proof is complete. A constructive proof also exists: Given an ideal I of R[X], let L be the set of leading coefficients of the elements of I. Then L is an ideal in R so is finitely generated by a1,... ,an in L, and pick f1,... ,fn in I such that the leading coefficient of fi is ai. Let di be the degree of fi and let N be the maximum of the di. Now for each k = 0, ..., N − 1 let Lk be the set of leading coefficients of elements of I with degree at most k. Then again, Lk is an ideal in R, so is finitely generated by ak1,... ,akmk say. As before, let fki in I have leading coefficient aki. Let H be the ideal in R[X] generated by the fi and the fki. Then surely H is contained in I and assume there is an element f in I not belonging to H, of least degree d, and leading coefficient a. If d is larger than or equal to N then a is in L so, a = r1a1 + ... + rnan and g = r1Xd−d1f1 + ... + rnXd−dnfn is of the same degree as f and has the same leading coefficient. Since g is in H, f − g is not, which contradicts the minimality of f. If on the other hand d is strictly smaller than N, then a is in Ld, so a = r1ad1 + ... + rmdadmd. A similar construction as above gives the same contradiction. Thus, I = H, which is finitely generated, and this finishes the proof.

7,703 | Marble | Marble. Taj Mahal, world-famous monument made of marble. Marble is a nonfoliated metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3). It is extensively used for sculpture, as a building material, and in many other applications. The word "marble" is colloquially used to refer to many other stones that are capable of taking a high polish. Etymology Venus de Milo, front. The word "marble" derives from the Ancient Greek μάρμαρον (mármaron) Marmaron, Henry George Liddell, Robert Scott, A Greek-English Lexicon, at Perseus or μάρμαρος (mármaros), "crystalline rock", "shining stone" Marmaros, Henry George Liddell, Robert Scott, A Greek-English Lexicon, at Perseus Marble, Compact Oxford English Dictionary , from the verb μαρμαίρω (marmaírō), "to flash, sparkle, gleam" Marmairō, Henry George Liddell, Robert Scott, A Greek-English Lexicon, at Perseus . This stem is also the basis for the English word marmoreal, meaning "marble-like." Origins Marble is a metamorphic rock resulting from regional or rarely contact metamorphism of sedimentary carbonate rocks, either limestone or dolomite rock, or metamorphism of older marble. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and/or dolomite crystals. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures present in the original rock. Pure white marble is the result of metamorphism of very pure limestones. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone. Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism. Types Some historically important kinds of marble, often named after their quarries, include the following: Marble name Color Location Country Aegean White White Volos Greece Beijing White White Beijing China Black Marble Basque Spain Black Marble Dębnik Poland Black Marble Kilkenny Ireland Onyx(Green) [Green] Baluchistan Pakistan Boticiena (Verona,Fancy,Cream,Rabbit) [Brown] Baluchistan Pakistan Ziarat White Grey and White Ziarat Baluchistan Pakistan Badal [White and Grey] Pakhtunkawa Pakistan Black and Gold [Black, Gold and White] Baluchistan Pakistan Chitral White [Grey and White] Pakhtunkawa Pakistan Tiipi and Tarwera [Brown] Baluchistan Pakistan Brač Island of Brač Croatia Brown marble Chęciny Poland Carrara marble white or blue-gray Carrara Italy Connemara marble Green Connemara Ireland Danby marble Danby, Vermont United States Durango Marble Coyote Quarry Mexico Fauske Norway Green Marble India Katni Marble Llano Pink Central Texas United States Luni marble Luni Italy Macael Spain Makrana Grayish white India Malagori White Pakistan Nabresina TriesteItaly Parian marble Fine-grained semitranslucent pure-white Island of Paros Greece Penteli Marble Flawless white with a uniform, faint yellow tint Penteli GreeceProconnesus Marble Island of Marmara Turkey Red Marble Ruşchiţa Romania Rosa Egeo Pink Volos GreeceRouge de Rance Red Rance Belgium Royal White White China Ruskeala Marble white, gray, black Ruskeala Finland/Russia Sivec or Macedonian Bianco Sivec White Prilep Republic of Macedonia Tennessee marble Pale pink to cedar-red Knox, Blount and Hawkins Counties, Tennessee United States Thassos Snow white, White, Grayish white, White with pink veining Island of Thassos Greece Vencac White White Arandjelovac Serbia Vietnam White Grayish White Vietnam Yule Uniform pure white Marble, Colorado United States Natural patterns on the polished surface of "landscape marble" can resemble a city skyline or even trees (see photo). White marbles, like Carrara in Italy, Royal White and Beijing White in China and Malagori of Pakistan, have been prized for sculpture since classical times. This preference has to do with the softness and relative isotropy and homogeneity, and a relative resistance to shattering. Also, the low index of refraction of calcite allows light to penetrate several millimeters into the stone before being scattered out, resulting in the characteristic "waxy" look which gives "life" to marble sculptures of the human body. Construction marble Folded and weathered marble at General Carrera Lake, Chile In the construction, specifically the dimension stone trade, the term "marble" is used for any crystalline calcitic rock (and some non-calcitic rocks) useful as building stone. For example, "Tennessee marble" is really a dense granular fossiliferous gray to pink to maroon Ordovician limestone that geologists call the Holston Formation. Industrial use Blocks of cut marble at the historic mill in Marble, Colorado. Colorless or light-colored marbles are a very pure source of calcium carbonate, which is used in a wide variety of industries. Finely ground marble or calcium carbonate powder is a component in paper, and in consumer products such as toothpaste, plastics, and paints. Ground calcium carbonate can be made from limestone, chalk, and marble; about three-quarters of the ground calcium carbonate worldwide is made from marble. Ground calcium carbonate is used as a coating pigment for paper because of its high brightness and as a paper filler because it strengthens the sheet and imparts high brightness. Ground calcium carbonate is used in consumer products such as a food additive, in toothpaste, and as an inert filler in pills. It is used in plastics because it imparts stiffness, impact strength, dimensional stability, and thermal conductivity. It is used in paints because it is a good filler and extender, has high brightness, and is weather resistant. However, the growth in demand for ground calcium carbonate in the last decade has mostly been for a coating pigment in paper. Calcium carbonate can also be reduced under high heat to calcium oxide (also known as "lime"), which has many applications including being a primary component of many forms of cement. Mississippian marble in Big Cottonwood Canyon, Wasatch Mountains, Utah, USA. Production Black Dębnik marble portal (17th century) of St. Wojciech's Church in Kraków. According to the United States Geological Survey, U.S. dimension marble production in 2006 was 46,400 tons valued at $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 2000-2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile. Artificial marble Faux marble or faux marbling is a wall painting technique that imitates the color patterns of real marble (not to be confused with paper marbling). Marble dust can be combined with cement or synthetic resins to make reconstituted or cultured marble. Cultural associations Marble from Italy. As the favorite medium for Greek and Roman sculptors and architects (see classical sculpture), marble has become a cultural symbol of tradition and refined taste. Its extremely varied and colorful patterns make it a favorite decorative material, and it is often imitated in background patterns for computer displays, etc. Places named after the stone include Marblehead, Ohio; Marble Arch, London; the Sea of Marmara; India's Marble Rocks; and the towns of Marble, Minnesota; Marble, Colorado; and Marble Hill, Manhattan, New York. The Elgin Marbles are marble sculptures from the Parthenon that are on display in the British Museum. They were brought to Britain by the Earl of Elgin.

7,704 | Creature_of_statute | A creature of statute is a legal entity such as a corporation created by statute. Thus, when a statute in some fashion requires the formation of a corporate body—often for governmental purposes—such bodies when formed are known as "creatures of statute." The same concept is also expressed with the phrase "creature of the state." Creature of the State -- Quaqua Society As a legal term, the meaning of "creature of statute" is most common to the United States: in the United Kingdom these bodies are simply called 'statutory corporations' or 'statutory bodies' and generally have some governmental function, e.g. the UK Atomic Energy Authority. In a wider sense, most companies in the UK are created under statute since the Companies Act 1985 specifies how a company may be created by a member of the public, but these companies are not called 'statutory corporations'. Often, in American legal and business documents that speak of governing bodies (e.g., a board that governs small businesses in China) these bodies are described as "creatures of statute" to inform readers of their origins and format although the national governments that created them may not term them as creatures of statute. Australia also uses the term "creature of statute" to describe some governmental bodies. The importance of a corporate body, regardless of its exact function, when such a body is a creature of statute is that its active functions can only be within the scope detailed by the statute which created that corporation. Thereby, the creature of statute is the tangible manifestation of the functions or work described by a given statute. The jurisdiction of a body that is a creature of statute is also therefore limited to the functional scope written into the laws that created that body. Unlike most (private) corporate bodies, creatures of statute cannot expand their business interests into other diverse areas. Creatures of statute, also known as creatures of the state, include corporations, municipalities, adoptions, and other artificial legal entities or relationships created solely through governmental edict.

7,705 | New_Oxford_American_Dictionary | The New Oxford American Dictionary (NOAD) is a single-volume dictionary of North American English compiled by American editors at the Oxford University Press. The current (second) edition contains more than 250,000 definitions. Erin McKean was its Principal Editor. NOAD is based upon the New Oxford Dictionary of English (NODE), published in the United Kingdom in 1998, although with substantial editing, additional entries, and the inclusion of illustrations. It is based on a corpus linguistics analysis of Oxford's 200 million word database of contemporary North American English. A notable difference is that the American counterpart uses a different scheme to convey pronunciations. NODE uses a modified IPA system (Gimson phonemic). In May 2005, a second edition (NOAD2) was published; it included a CD-ROM with the full text of the dictionary for Palm OS devices. Since 2005 Apple Inc.'s Mac OS X operating system has come bundled with a dictionary application and widget which credits as its source "Oxford American Dictionaries", and contains the full text of NOAD2. The Amazon Kindle reading device also uses NOAD as its built-in dictionary. Oxford University Press published NOAD2 in electronic form in 2006 at http://www.oxfordamericandictionary.com/.

7,706 | CD-R | Compact Disc Recordable (CD-R) logo/trademark A CD-R (Compact Disc-Recordable) is a variation of the Compact Disc invented by Philips and Sony. CD-R is a Write Once Read Many (WORM) optical medium, though the whole disk does not have to be entirely written in the same session. CD-R retains a high level of compatibility with standard CD readers, unlike CD-RW - which can be re-written, but has lower compatibility and uses more expensive media. History Assorted CD-Rs The CD-R, originally named CD Write-Once (WO), specification was first published in 1988 by Philips and Sony in the 'Orange Book'. The Orange Book consists of several parts, furnishing details of the CD-WO, CD-MO (Magneto-Optic), and CD-RW (ReWritable). The latest editions have abandoned the use of the term "CD-WO" in favor of "CD-R", while "CD-MO" were very little used. Written CD-Rs and CD-RWs are, from a technical standpoint, fully compatible with the Audio CD (Red Book) and CD-ROM (Yellow Book) standards, although some hardware compatible with Red Book CDs may have difficulty reading CD-Rs and especially CD-RWs. They use Eight-to-Fourteen Modulation, CIRC error correction plus the third error correction layer defined for CD-ROM. The dye materials developed by Taiyo Yuden made it possible for CD-R discs to be compatible with Audio CD and CD-ROM discs. Initially in the United States, there was a market separation between "music" CD-Rs and "data" CD-Rs, the former being several times more expensive than the latter due to industry copyright arrangements with the RIAA. A New Spin, TIME Magazine, August 24, 1998 Physically, there is no difference between the discs save for the Disc Application Flag that identifies their type: standalone audio recorders will only accept "music" CD-Rs to enforce the RIAA arrangement, while computer CD-R drives can use either type of media to burn either type of content. What's the difference between "data" and "music" blanks? Physical characteristics Photomicrograph of the groove in a CD-R discA standard CD-R is a 1.2 mm thick disc made of polycarbonate with a 120 mm or 80 mm diameter. The 120 mm disc has a storage capacity of 74 minutes of audio or 650 MiB of data. CD-R/RWs are also available with capacities of 79 minutes, 59 seconds and 74 frames (marketed as 80 minutes) / 736,966,656 bytes (702 MiB), which they achieve by molding the disc at the tightest allowable tolerances specified in the Orange Book CD-R/CD-RW standards. The engineering margin that was reserved for manufacturing tolerance has been used for data capacity instead, leaving no tolerance for manufacturing--for these discs to truly be compliant with the Orange Book standard, the manufacturing process must be perfect. Most CD-Rs on the market have an 80 minute capacity. There are also 90 minute/790 MiB and 99 minute/870 MiB discs, although they are less common (and violate the Orange Book standard; note that nothing in the Red, Yellow or Orange Book standards says that disc reading/writing devices may not have the capacity to read discs beyond the standard.) Some drives use special techniques to write more data onto a given disc, such as Plextor's GigaRec allowing as much as 1.2 GB to be recorded onto a 99 minute disc; these techniques inherently are deviations from the Compact Disc (Red, Yellow, and/or Orange Book) standards, making the recorded discs proprietary-formatted and not fully compatible with standard CD players and drives. However, in certain applications where discs will not be distributed or exchanged outside a private group and will not be archived for a long time, a proprietary format may be acceptable for greater capacity. Also, due to the limitations of the data structures in the ATIP (see below), 90 and 99 minute blanks will identify as 80 minute ones and have to be burned using "overburn" options in the CD recording software. (Overburning itself is so named because it is outside the written standards, but it has become a de facto standard function in most CD writing drives and software for them.) (Note: While disc players and drives may have capabilities beyond the standards such that they are able to use nonstandard discs, there is no assurance, in the absence of explicit additional manufacturer specifications beyond normal Compact Disc logo certification, that any particular player or drive will perform beyond the standards at all or consistently. Furthermore, if the same device with no explicit performance specs beyond the Compact Disc logo initially handles nonstandard discs reliably but later stops doing so, there is no assurance that it can be fixed to do so again. Therefore, discs with capacities larger than 650 MiB and especially larger than 800 MiB are less interchangeable among players/drives and are not very suitable for archival use, as their readability on future equipment is not assured.) The polycarbonate disc contains a spiral groove, called the "pregroove" (because it is molded in before data are written to the disc), to guide the laser beam upon writing and reading information. The pregroove is molded into the top side of the polycarbonate disc, where the pits and lands would be molded if it were a pressed (nonrecordable) Red Book CD; the bottom side, which faces the laser beam in the player or drive, is flat and smooth. The polycarbonate disc is coated on the pregroove side with a very thin layer of organic dye. Then, on top of the dye is coated a thin, reflecting layer of silver, a silver alloy, or gold. Finally, a protective coating of a photo-polymerizable lacquer is applied on top of the metal reflector and cured with UV-light. A blank CD-R is not "empty"; the pregroove has a wobble (the ATIP), which helps the writing laser to stay on track and to write the data to the disc at a constant rate. Maintaining a constant rate is essential to ensure proper size and spacing of the pits and lands burned into the dye layer. As well as providing timing information, the ATIP (absolute time in pregroove) is also a data track containing information about the CD-R manufacturer, the dye used and media information (disc length etc). The pregroove is not destroyed when the data are written to the CD-R, a point which some copy protection schemes use to distinguish copies from an original CD. There are three basic formulations of dye used in CD-Rs: Cyanine dye CD-Rs were the earliest ones developed, and their formulation is patented by Taiyo Yuden. CD-Rs based on this dye are mostly green in color. The earlier models were very chemically unstable and this made cyanine based discs unsuitable for archival use; they could fade and become unreadable in a few years. Many manufacturers like Taiyo Yuden use proprietary chemical additives to make more stable cyanine discs ("metal stabilized Cyanine", "Super Cyanine"). Older cyanine dye based CD-Rs, as well as all the hybrid dyes based on cyanine, were very sensitive to UV-rays and could have become unreadable after only a few days if they were exposed to direct sunlight. Although the additives used have made cyanine more stable, it is still the most sensitive of the dyes in UV rays (showing signs of degradation within a week of direct sunlight exposure). A common mistake users make is to leave the CD-Rs with the "clear" (recording) surface upwards, in order to protect it from scratches, as this lets the sun hit the recording surface directly. Phthalocyanine dye CD-Rs are usually silver, gold or light green. The patents on phthalocyanine CD-Rs are held by Mitsui and Ciba Specialty Chemicals. Phthalocyanine is a natively stable dye (has no need for stabilizers) and CD-Rs based on this are often given a rated lifetime of hundreds of years. Unlike cyanine, phthalocyanine is more resistant to UV rays and CD-Rs based on this dye show signs of degradation only after two weeks of direct sunlight exposure. However, phthalocyanine is more sensitive than cyanine to writing laser power calibration, meaning that the power level used by the writing laser has to be more accurately adjusted for the disc in order to get a good recording; this may erode the benefits of dye stability, as marginally written discs (with higher correctable error rates) will lose data (i.e. have uncorrectable errors) after less dye degradation than well written discs (with lower correctable error rates). Azo dye CD-Rs are dark blue in color, and their formulation is patented by Mitsubishi Chemical Corporation. Azo dye is also chemically stable, and Azo CD-Rs are typically rated with a lifetime of decades. Azo is the most resistant dye against UV rays and begins to degrade only after the third or fourth week of direct sunlight exposure. More modern implementations of this kind of dye include Super Azo which is not as deep blue as the earlier Metal Azo. This change of composition was necessary in order to achieve faster writing speeds. There are many hybrid variations of the dye formulations, such as Formazan by Kodak (a hybrid of cyanine and phthalocyanine). Although the CD-R was initially developed in Japan, most of the production of CD-Rs had moved to Taiwan by 1998, and also to Mainland China, Hong Kong, Malaysia and India. Taiwanese manufacturers supplied more than 70% of the worldwide production volume of 10.5 billion CD-Rs in . Unfortunately, many manufacturers have added additional coloring to disguise their unstable cyanine CD-Rs in the past, so the formulation of a disc cannot be determined based purely on its color. Similarly, a gold reflective layer does not guarantee use of phthalocyanine dye. The quality of the disc is also not only dependent on the dye used, it is also influenced by sealing, the top layer, the reflective layer, and the polycarbonate. Simply choosing a disc based on its dye type may be problematic. Furthermore, correct power calibration of the laser in the writer, as well as correct timing of the laser pulses, stable disc speed, etc., is critical to not only the immediate readability but the longevity of the recorded disc, so for archiving it is important to have not only a high quality disc but a high quality writer. In fact, a high quality writer may produce adequate results with medium quality media, but high quality media cannot compensate for a mediocre writer, and discs written by such a writer cannot achieve their maximum potential archival lifetime.

Also, above 20X speed, drives use a Zoned-CLV strategy, where the advertised maximum speed is only reached near the outer rim of the disc. Explanation of CLV, CAV, P-CAV and Z-CLV with diagrams This is not taken into account by the above table. Writing methods The blank disc has a pre-groove track onto which the data are written. The pre-groove track, which also contains timing information, ensures that the recorder follows the same spiral path as a conventional CD. A CD recorder writes data to a CD-R disc by pulsing its laser to heat areas of the organic dye layer. The writing process does not produce indentations (pits); instead, the heat permanently changes the optical properties of the dye, changing the reflectivity of those areas. Using a low laser power, so as not to further alter the dye, the disc is read back in the same way as a CD-ROM. However, the reflected light is modulated not by pits, but by the alternating regions of heated and unaltered dye. The change of the intensity of the reflected laser radiation is transformed into an electrical signal, from which the digital information is recovered ("decoded"). Once a section of a CD-R is written, it cannot be erased or rewritten, unlike a CD-RW. A CD-R can be recorded in multiple sessions. A CD recorder can write to a CD-R using several methods including: Disc At Once - the whole CD-R is written in one session with no gaps and the disc is "closed" meaning no more data can be added and the CD-R effectively becomes a standard read-only CD. With no gaps between the tracks the Disc At Once format is useful for "live" audio recordings. Track At Once - data are written to the CD-R one track at a time but the CD is left "open" for further recording at a later stage. It also allows data and audio to reside on the same CD-R. Packet Writing - used to record data to a CD-R in "packets", allowing extra information to be appended to a disc at a later time, or for information on the disc to be made "invisible". In this way, CD-R can emulate CD-RW; however, each time information on the disc is altered, more data has to be written to the disc. There can be compatibility issues with this format and some CD drives. With careful examination, the written and unwritten areas can be distinguished by the naked eye. CD-Rs are written from the center outwards, so the written area appears as an inner band with slightly different shading. Expected lifespan At present, stated CD-R lifetimes are estimates based on accelerated aging tests, as the technology has not been in existence long enough to verify the upper range, 120 years. With proper care it is thought that CD-Rs should be readable one thousand times or more and have a shelf life of three to five years. Common handling practices can reduce shelf life to only one or two years. Real-life (not accelerated aging) tests have revealed that some CD-Rs degrade quickly even if stored normally. The quality of a CD-R disc has a large and direct influence on longevity -- cheap discs shouldn't be expected to last very long. Unfortunately, branding isn't a terribly good guide to quality, because many brands (major as well as no name) do not actually manufacture their own discs. Instead they are sourced from different manufacturers of varying quality. For best results, verify the actual manufacturer and material components of each batch of discs. An example of a CD-R burned in 2000 showing dye degradation. Part of the data on it has been lost.Burned CD-Rs suffer from material degradation, just like most writable media. CD-R media have an internal layer of dye used to store data. In a CD-RW disc, the recording layer is made of an alloy of silver and other metals — indium, antimony, and tellurium. In CD-R media, the dye itself can degrade causing data to become unreadable. As well as degradation of the dye, failure of a CD-R can be due to the reflective surface. While silver is less expensive and more widely used, it is more prone to oxidation resulting in a non-reflecting surface. Gold on the other hand, although more expensive and no longer widely used, is an inactive material and so, gold-based CD-Rs do not suffer from this problem. Paper paste-on labels for CD-Rs have been linked to degradation of the recording surface, although the issue is not without controversy CD-R Labeling . Permanent markers are commonly used to mark the label side of CD-Rs and DVDs. This practice has been discouraged because it is believed xylene and toluene, common substances in permanent marker ink, can cause surface deterioration. Additionally, volatile organic compounds may be released which will remain inside the enclosed atmosphere of a CD-R's storage box, causing harm. Cleaning CD-Rs The error correction of most modern optical drives/players can usually read effectively through fingerprints as well as a highly scratched information surface. Dust can be removed from a CD's surface using compressed air or by very lightly wiping the information side with a very soft cloth (such as an eyeglass cleaning cloth) from the center of the disc in an outward direction. Wiping the information surface of any type of CD in a circular motion around the center, however, has been known to create scratches in the same direction as the information and potentially cause data loss. Fingerprints or stubborn dust can be removed from the information surface by wiping it with a cloth dampened with diluted dish detergent (then rinsing) or alcohol (methylated spirits or isopropyl alcohol) and again wiping from the center outwards, with a very soft cloth (non-linting : polyester, nylon, etc.). It is harmful, however, to use acetone, nail polish remover, kerosene, petrol/gasoline, or any other type of petroleum-based solvent to clean a CD-R; the use of petroleum based solvents will damage the polycarbonate surface and the CD-R will become unreadable. Readability in CD drives There was some incompatibility with CD-Rs and older CD-ROM drives. This was primarily due to the lower reflectivity of the CD-R disc. In general, CD-ROM drives marked as 8x or greater will read CD-R discs. Some DVD players will not read CD-Rs because of this change in reflectivity as well. Burn speed can also affect the compatibility due to worse jitter on disks recorded at higher speeds; selecting a slower speed can improve compatibility, especially for CD-DA. However, for writing some burners may not perform best at their lowest speed, and may not perform best on all discs at the same speed; each burner/media combination has an optimal speed which is most likely a lower rather than higher speed but can only be certainly known by testing that combination at different speeds (using disc checking software such as that which reports C1/C2 errors to compare the quality of readable discs.). Disposal Security risk Since CD-Rs cannot be logically erased to any degree, disposal of CD-Rs presents a possible security issue if it contains sensitive data. Destroying the data requires physically destroying the disc or data layer. Recycling The polycarbonate material and possible gold or silver in the reflective layer would make CD-Rs highly recyclable. However, the polycarbonate is of very little value and the quantity of precious metals is so small that it isn't profitable to recover them. The Consumer Recycling Guide: Recycling More Obscure Materials (toxics, batteries, mercury, computers, eyeglasses, foam peanuts) Consequently, recyclers that accept CD-Rs typically do not offer compensation for donating or transporting the materials.

7,707 | Lethe | In Classical Greek, Lethe (λήθη; Classical Greek [ˈlεːt̪ʰεː], modern Greek: [ˈliθi]) literally means "forgetfulness" or "concealment". It is related to the Greek word for "truth": a-lethe-ia (αλήθεια), meaning "un-forgetfulness" or "un-concealment". In Greek mythology, Lethe is one of the several rivers of Hades: those who drank from it experienced complete forgetfulness. Lethe was also a naiad, although the naiad Lethe is probably a separate personification of forgetfulness rather than a reference to the river which bears her name. She was the daughter of Eris ('Strife' in Hesiod's Theogony), and sister to Algos, Limos, Horcus, and Ponos. Role in religion and philosophy Some ancient Greeks believed that souls were made to drink from the river before being reincarnated, so they would not remember their past lives. The Myth of Er at the end of Plato's Republic tells of the dead arriving at the "plain of Lethe", which the river Ameles ("careless") runs through. A few mystery religions taught the existence of another river, the Mnemosyne; those who drank from the Mnemosyne would remember everything and attain omniscience. Initiates were taught that they would receive a choice of rivers to drink from after death, and to drink from Mnemosyne instead of Lethe. These two rivers are attested in several verse inscriptions on gold plates dating to the 4th century BC and onward, found at Thurii in Southern Italy and elsewhere throughout the Greek world. There were rivers of Lethe and Mnemosyne at the oracular shrine of Trophonius in Boeotia, from which worshippers would drink before making oracular consultations with the god. More recently, Martin Heidegger used "lēthē" to symbolize the "concealment of Being" or "forgetting of Being" that he saw as a major problem of modern philosophy. Examples are found in his books on Nietzsche (Vol 1, p. 194) and on Parmenides. Real rivers The River Lethe in Alaska. Amongst authors in Antiquity, the tiny Limia River near Xinzo de Limia in the province of Ourense in Galicia (Spain) was said to have the same properties of memory loss as the legendary Lethe River. In 138 BC, the Roman general Decimus Junius Brutus sought to dispose of the myth, as it impeded his military campaigns in the area. He was said to have crossed the Limia and then called his soldiers on the other side, one by one, by name. The soldiers, astonished that their general remembered their names, crossed the river as well without fear. This act proved that the Limia was not as dangerous as the local myths described. In Alaska, a river which runs through the Valley of Ten Thousand Smokes is called River Lethe. Poetry Walter Savage Landor transforms into substance the metaphor that time takes flight when he places a few drops of Lethe's waters on wing: On love, on grief, on every human thing, Time sprinkles Lethe's water with his wing. In The Divine Comedy, the stream of Lethe flows to the centre of the earth from its surface, but its headwaters are located in the Earthly Paradise found at the top of the mountain of Purgatory. In John Keats' poem, "Ode on Melancholy", the first line begins "No, no! Go not to Lethe". In his Ode to a Nightingale the "Lethe-wards" are said to have sunk into the narrator and created a "drowsy numbness". The fourth stanza of the fourth canto of Byron's "Don Juan" reads: "And if I laugh at any mortal thing, 'T is that I may not weep; and if I weep, 'T is that our nature cannot always bring Itself to apathy, for we must steep Our hearts first in the depths of Lethe's spring, Ere what we least wish to behold will sleep: Thetis baptized her mortal son in Styx; A mortal mother would on Lethe fix." In his poem "The Sleeper," Edgar Allan Poe describes a 'sleeping' "universal valley" that includes a Lethe-like body of water. "Looking like Lethe, see! the lakeA conscious slumber seems to take,And would not, for the world, awake." Charles Baudelaire's poem "Spleen" ends with the lines "II n'a su réchauffer ce cadavre hébétéOù coule au lieu de sang l'eau verte du Léthé" ("He failed to warm this dazed cadaver in whose veinsFlows the green water of Lethe in place of blood."). Baudelaire also wrote a poem entitled "Le Léthé" ("Lethe"), in which an adored but cruel woman serves as a metaphor for the oblivion of the river Lethe. French Romantic poet Alphonse de Lamartine refers to the Lethe river in "Le Vallon" (The Vale) J'ai trop vu, trop senti, trop aimé dans ma vie; Je viens chercher vivant le calme du Léthé. (I have seen too much, felt too much, love too much in my life; I come to seek, still living, the calm of Lethe.) In Hymn to Proserpine (1866) by Algernon Charles Swinburne, the line "We have drunken of things Lethean..." laments the decline of pagan tradition and beliefs in ancient Rome following the endorsement of Christianity as the official religion. The Edna St. Vincent Millay poem "Lethe" describes the river as "the taker-away of pain,And the giver-back of beauty!" In "The Scarlet Woman", a poem by African-American poet Fenton Johnson (1888-1958), a young woman resorts to prostitution in order to avoid starvation. The poem concludes with the lines "Now I can drink more gin than any man for miles around.Gin is better than all the water in Lethe." "Getting There", a 1962 poem by Sylvia Plath, ends with the lines "And I, stepping from this skinOf old bandages, boredoms, old facesStep up to you from the black car of Lethe,Pure as a baby." The river Lethe is mentioned in Allen Ginsberg's poem "A Supermarket in California". Billy Collins, in his poem "Forgetfulness", refers to "a dark mythological riverwhose name begins with an L as far as you can recall". in "Sonnet V: To the River Downs" Charlotte Smith asks the river Lethe for forgetfulness: "As to the sea your limpid waves you bear, Can you one kind Leathean cup bestow, To drink a long oblivion to my care?" Also mentioned in Byron's poem "Remember Thee! Remember Thee!". In the Aeneid by Vergil, in book 6 Aeneas sees the future Roman heroes drinking from the River Lethe. "The drink the soothing fluid and long forgetfullness" Novels James L. Grant's horror novel, On the Banks of Lethe, a reference to the books theme of lost memories. In chapter 4 of Nathaniel Hawthorne's novel, The Scarlet Letter, Roger Chillingworth claims, "I know not Lethe nor Nepenthe." In Robert A. Heinlein's Time Enough for Love there is a reference to "Neolethe" (see the chapter entitled Counterpoint I), which is apparently a powerful sedative. In Toni Morrison's novel Beloved, the main character's name is Sethe, a pseudonym based on the idea of the power of water, particularly the motif that water can weather her past. In Bram Stoker's Dracula, Dr. Abraham Van Helsing states to Lucy "It smell so like the waters of Lethe..."(Stoker, 192) talking about the garlic which he was going to place around her room so the Dracula would not suck her blood. C. S. Lewis refers to Lethe in The Great Divorce when he writes, “‘It is up there in the mountains, very cold and clear, between two green hills. A little like Lethe. When you have drunk of it you forget forever all proprietorship in your own works". The Spirit who talks about the fountain is describing Heaven to an artist, telling him that soon he will forget all ownership of his work. In the volume, Swann's Way, of Marcel Proust's novel, À la recherche du temps perdu (In Search of Lost Time), the narrator comments, as he recollects a seemingly lost memory, "...trying to remember, feeling deep within myself a tract of soil reclaimed from the waters of Lethe slowly drying until the buildings rise on it again;" The unnamed narrator of Sasha Sokolov's first novel, A School for Fools, has a significant habit of referring to the river running through his neighborhood in the Russian countryside as Lethe. Henry David Thoreau wrote in Walking: "The Atlantic is a Lethean stream, in our passage over which we have had an opportunity to forget our Old World and its institutions. If we do not succeed this time, there is perhaps one more chance for the race left before it arrives on the banks of the Styx; and that is in the Lethe of the Pacific, which is three times as wide." In chapter 17 of Graham Greene's novel The Tenth Man, the protagonist Charlot watches the charlatan Carosse beguile the vulnerable Mademoiselle Mangeot: "He knew the game so well, Charlot thought: the restless playboy knew how to offer what most people wanted more than love--peace. The words flowed like water--the water of Lethe." In Stephen King's novel Rose Madder, Rose, in preparation for retrieving the title character's child from a labyrinth, is warned not to drink from the water from a river she must cross. Later in the story, a few drops of that water, mixed in a soft drink, is used to remove Bill's memories of the latter part of the book's events. In Piers Anthony's With a Tangled Skein, Niobe accompanies her daughter and granddaughter on a quest to acquire an enchanted paint brush and a harp. During the quest, the trio must cross an illusory representation of the Lethe. Later, in Hell, Niobe must again cross a river, and wonders if it might be the actual Lethe. In Valeer Damen’s novel KATABASIS, one of the main characters has to find and cross the river Lethe as a step in the process of entering the afterlife. “‘There is the plain. Transit. Like a battlefield. All the energy totals of actions and thoughts are there. Wind blows. Tests are there, functionaries, agents from above and below. Introduction functionary cannot help solve tests or help in final adjudication. In the end, river.’” (Damen, 21). Plays In William Shakespeare's play Julius Caesar, Antony, on seeing the murderers' hands red with Caesar's blood, observes: "Here didst thou fall; and here thy hunters stand,/Sign'd in thy spoil, and crimson'd in thy Lethe" (III.i.215). Additionally, the character of Sebastian refers to Lethe in Shakespeare's Twelfth Night: "Let fancy still my sense in Lethe steep; If it be thus to dream, still let me sleep!" (IV.ii.61). In William Shakespeare's play Hamlet, Hamlet's father's Ghost says to the prince, "I find thee apt, And duller shouldst thou be than the fat weed That roots itself in ease on Lethe wharf, Wouldst thou not stir in this." (Act 1, scene V). In Antony and Cleopatra, Sextus Pompey talks of Antony's supposed military inertia, hoping that "Epicurean cooks / Sharpen with cloyless sauce his appetite, / That sleep and feeding may prorogue his honour / Even till a Lethe'd dullness-" (II.i.24-27). In John Webster's play The White Devil, the duke Brachiano in his death throes says to Vittoria, whose husband he conspired to murder, along with his own wife: Brac. I have drunk Lethe. Vittoria? / My dearest happiness? Vittoria? (IV.ii.129-30) In Samuel Beckett's radio play Embers, the main character Henry describes conversing with his dead wife: "that's what hell will be like, small chat to the babbling of Lethe about the good old days when we wished we were dead". In Sarah Ruhl's Eurydice, the river Lethe is a central theme of the play. All the shades must drink from Lethe and become like stones, speaking in their inaudible language and forgetting everything of the world. In Offenbach's operetta Orpheus in the Underworld, the character John Styx drinks the waters of Lethe in a deliberate attempt to forget things. His forgetfulness is a significant factor in the plot of the last act. Movies In Roy Andersson's You, the Living, a quotation from Goethe's Roman Elegies "Be pleased then, you the living, in your delightfully warmed bed, before Lethe’s ice-cold wave will lick your escaping foot" is presented as an epigraph. Later, a tram is seen with "Lethe" as its destination. Television In Gene Roddenberry's Andromeda there is an entire episode entitled The Banks of the Lethe.

7,708 | MOS_Technology | MOS Technology, Inc., also known as CSG (Commodore Semiconductor Group), was a semiconductor design and fabrication company based in Norristown, Pennsylvania, in the United States. It is most famous for its 6502 microprocessor, and various designs for Commodore International's range of home computers. History MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor) was originally started up to provide a second source for Texas Instruments designed electronic calculators and the chips inside them. They also produced Atari's custom Pong chip for a short time. As the calculator market grew MOS eventually became largely beholden to Commodore Business Machines, who bought practically all of their supply for their line of calculators. Another theory on the calculator line drying up is somewhat more conspiratorial. It states that Commodore deliberately overbought MOS's chip line to monopolize it, and warehoused the extras. Then, with several months worth stored, they stopped buying anything and MOS's sales died. This forced MOS to sell to Commodore. Things changed dramatically in 1975. Several of the designers of the Motorola 6800 left the company shortly after its release, apparently in disgust. At the time there was no such thing as a "design-only" firm (known as a fabless semiconductor company today), so they had to join a chip-building company to produce any of their designs. MOS was a small firm with good credentials in the right area, the East coast of the USA. The team of four design engineers was headed by Chuck Peddle and included Bill Mensch. At MOS they set about building a new CPU that would outperform the 6800 while being similar to it in purpose. The resulting 6501 design was somewhat similar to the 6800, but by using several simplifications in the design, the 6501 would be up to four times faster. Mask fixing In addition, MOS had a secret weapon: the ability to "fix" its masks. Phone conversation with Bill Mensch. Masks are the large drawings of the chip that are photo-reduced to make the pattern from which chips are made – a process similar to photocopying. All masks end up with flaws, both as a result of design problems in the chip itself, as well as side effects from the photo-reduction process. When a chip is made with this mask there is a chance that some of these flaws will end up "expressed" on the chip. If too many of them are expressed, that particular chip will not work. If a chip design with five design flaws results in a mask with ten flaws in total, there is no point in making another mask because it will have the same five design flaws plus some other set of five copying flaws. So companies simply built chips with these masks, and threw away broken chips. In the late 1970s this meant throwing away 70% or more of the completed chips. The price of a chip is largely defined by the yield, the measure of how many work, so improving this number can lower the price and raise the gross profit dramatically. MOS's engineers had learned the trick of fixing their masks after they were made. This allowed them to correct the major flaws in a series of small fixes, eventually producing a mask with a very low flaw rate. The company's production lines typically reversed the numbers others were achieving; even the early runs of a new CPU design –what would become the 6502– were achieving a success rate of 70% or better. This meant that not only were its designs faster, they cost much less as well. 6502 family When the 6501 was announced, Motorola launched a lawsuit almost immediately. Although the 6501 was not compatible with the 6800, it could nevertheless be plugged into existing motherboard designs because it used the same arrangement of pins. That was enough, apparently, to allow Motorola to sue. Sales of the 6501 basically stopped, and the lawsuit would drag on for many years before MOS was eventually forced to pay a paltry 200,000 USD in fines. In the meantime the 6502 had gone on sale at 1 MHz in September 1975 for a mere 25 USD. It was essentially identical to the 6501, differing only in pin layout. It outperformed the more complex 6800 and Intel 8080, but cost much less and was easier to work with. Although it did not have the advantage of being able to be used in existing Motorola hardware like the 6501, it was so inexpensive that it quickly became more popular than the 6800, making that a moot point. Image of the circuit board of a Commodore 64 showing some important MOS Technology circuits: the 6510 CPU (long chip, lower left) and the 6581 SID (right). The production week/year (WWYY) of each chip is given below its name. The 6502 was so cheap, that many people believed it was a scam when MOS first showed it at a 1975 trade show. They were not aware of MOS's masking techniques and when they calculated the price per chip at normal yield rates it did not add up. But any hesitation to buy it evaporated when both Motorola and Intel dropped the prices on their own designs from $179 to $69 at the same show in order to compete. Their moves legitimized the 6502. By show's end the wooden barrel full of samples was empty. The 6502 would quickly go on to be one of the most popular chips of its day. A number of companies licensed the 650x line from MOS, including Rockwell International, GTE, Synertek, and Western Design Center (WDC). A number of different versions of the basic CPU, known as the 6503 through 6507, were offered in 28-pin packages for lower cost. The various models removed signal or address pins. Far and away the most popular of these was the 6507, which was used in the Atari 2600 and in Atari disk drives. The 6504 was sometimes used in printers. MOS also released a series of similar CPUs using external clocks, which added a "1" to the name in the 3rd digit, as the 6512 through 6515. These were useful in systems where the clock support was already being provided on the motherboard by some other chip. The final addition was the "crossover" 6510, used in the Commodore 64, with additional I/O ports. Commodore Semiconductor Group However successful the 6502 was, the company itself was having problems. At about the time the CPU was released the entire calculator market collapsed, and MOS's only existing products stopped shipping. Soon they were in serious financial trouble. Rescue came in the form of Commodore, who in 1976 bought the entire company in a stock trade, on the condition that Chuck Peddle would join Commodore as chief engineer. The deal went through, and while the firm basically became Commodore's production arm, they continued using the name MOS for some time so that manuals would not have to be reprinted. After a while MOS became the Commodore Semiconductor Group (CSG). Despite being renamed to CSG, all chips produced were still stamped with the old "MOS" logo until 1989. MOS had previously designed a simple computer kit called the KIM-1, primarily to "show off" the 6502 chip. At Commodore, Peddle convinced the owner, Jack Tramiel, that calculators were a dead end, and that home computers would soon be huge. A repackaged KIM with a new display driver and keyboard became the Commodore PET computer. However, the original design group appeared to be even less interested in working for Jack Tramiel than it had for Motorola, and the team quickly started breaking up. One result was that the newly-completed 6522 (VIA) chip was left undocumented for years. Bill Mensch left MOS even before the Commodore takeover, and moved home to Mesa, AZ from MOS's Norristown, PA. After a short stint consulting for a local company called ICE, he set up the Western Design Center (WDC) in 1978. As a licensee of the 6502 line, their first products were bug-fixed, power-efficient CMOS versions of the 6502 (the 65C02, both as a separate chip and embedded inside a microcontroller called the 65C150). But then they expanded the line greatly with the introduction of the 65816, a fairly straightforward 16-bit upgrade of the original 65C02 that could also run in 8-bit mode for compatibility. The design of the similar-in-concept 32-bit 65832 CPU was completed, but not put into production. Since then WDC have moved much of the original MOS catalog to CMOS, and the 6502 continues to be a popular CPU in embedded systems, like medical equipment and car dashboard controllers. GMT Microelectronics After Commodore's bankruptcy in 1994, Commodore Semiconductor Group, MOS's successor, was bought by its former management for about $4.3 million, plus an additional $1 million to cover miscellaneous expenses including EPA liens. Dennis Peasenell became CEO. In December 1994, EPA entered into a Prospective Purchase Agreement (limiting the company's liability in exchange for sharing the costs of cleanup) with GMT Microelectronics. In 1995, the company, operating under the name GMT Microelectronics (Great Mixed-signal Technologies), reopened MOS Technologies' original, circa-1970 one-micrometre fab in Norristown, Pennsylvania that Commodore had closed in 1992. GMT would have provided foundry services based on TelCom's Bipolar and SiCr Thin Film Resistor processes and would have been licensed alternate sources for TelCom's Bipolar based products. With production running at 10000 wafers (size 5) per month, producing CMOS BiCMOS NMOS BIPOLAR SOI. The plant had been on the EPA's National Priorities List of hazardous waste sites since 1989. By 1999 it had $21 million in revenues and 183 employees, within 3 years. However, in 2001 the EPA shut the plant down. GMT ceased operations and was liquidated.

7,709 | Amicable_numbers | Amicable numbers are two different numbers so related that the sum of the proper divisors of one of the numbers is equal to the other. (A proper divisor of a number is a positive integer divisor other than the number itself. For example, the proper divisors of 6 are 1, 2, and 3.) A pair of amicable numbers constitutes an aliquot sequence of period 2. A related concept is that of a perfect number, which is a number which equals the sum of its own proper divisors, in other words a number which forms an aliquot sequence of period 1. For example, the smallest pair of amicable numbers is (220, 284); for the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, of which the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71, and 142, of which the sum is 220. The first few amicable pairs are: (220, 284), (1184, 1210), (2620, 2924), (5020, 5564), (6232, 6368) . History Amicable numbers were known to the Pythagoreans, who credited them with many mystical properties. A general formula by which these numbers could be derived was invented circa 850 by Thābit ibn Qurra (826-901). Other Arab mathematicians who studied amicable numbers are al-Majriti (died 1007), al-Baghdadi (980-1037), and al-Fārisī (1260-1320). The Iranian mathematician Muhammad Baqir Yazdi (16th century) discovered the pair (9363584, 9437056), though this has often been attributed to Descartes. Much of the work of Eastern mathematicians in this area has been forgotten. Thābit's formula was rediscovered by Fermat (1601-1665) and Descartes (1596-1650), to whom it is sometimes ascribed, and extended by Euler (1707–1783). It was extended further by Borho in 1972. Fermat and Descartes also rediscovered pairs of Amicable numbers known to Arab mathematicians. Euler also discovered dozens of new pairs. The second smallest pair, (1184, 1210), was discovered in 1866 by a then teen-aged B. Nicolò I. Paganini, having been overlooked by earlier mathematicians. As of 1946 there were 390 known pairs, but the advent of computers has allowed the discovery of many thousands since then. Exhaustive searches have been carried out to find all pairs less than a given bound, this bound being extended from 108 in 1970, to 1010 in 1986, 1011 in 1993, and to a bound well over that today. Rules for generating Thābit's rule states that if p = 3 × 2n − 1 − 1, q = 3 × 2n − 1, r = 9 × 22n − 1 − 1, where n > 1 is an integer and p, q, and r are prime numbers, then 2npq and 2nr are a pair of amicable numbers. This formula gives the pairs (220, 284) (n=2), (17296, 18416) (n=4), and (9363584, 9437056) (n=7), but no such pairs are known. Numbers of the form 3 × 2n − 1 are known as Thabit numbers. In order for Thābit's formula to produce an amicable pair, two consecutive Thabit numbers must be prime; this severely restricts the possible values of n. A generalization of this is Euler's rule, which states that if p = (2(n - m)+1) × 2m − 1, q = (2(n - m)+1) × 2n − 1, r = (2(n - m)+1)2 × 2m + n − 1, where n>m> 0 are integers and p, q, and r are prime numbers, then 2npq and 2nr are a pair of amicable numbers. Thābit's rule corresponds to the case m=n-1. Euler's rule creates additional amicable pairs for (m,n)=(1,8), (29,40) with no others being known. While these rules do generate some pairs of amicable numbers, many other pairs are known, so these rules are by no means comprehensive. Regular pairs Let (m, n) be a pair of amicable numbers with m<n, and write m=gM and n=gN where g is the greatest common divisor of m and n. If M and N are both prime to g and square free then the pair (m, n) is said to be regular, otherwise it is called irregular or exotic. If (m, n) is regular and M and N have i and j prime factors respectively, then (m, n) is said to be of type (i, j). For example, with (m, n) = (220, 284), the greatest common divisor is 4 and so M = 55 and N = 71. Therefore (220, 284) is regular of type (2, 1). There no amicable pairs of type (1, j) for any j. Other results In every known case, the numbers of a pair are either both even or both odd. It is not known whether an even-odd pair of amicable numbers exists. Also, every known pair shares at least one common factor. It is not known whether a pair of coprime amicable numbers exists, though if any does, the product of the two must be greater than 1067. Also, a pair of coprime amicable numbers cannot be generated by Thabit's formula (above), nor by any similar formula. Notes References Wells, D. (1987).

7,710 | Ninth_Fort | Reconstructed Ninth Fort Observation post. The Ninth Fort (Devintas Fortas in Lithuanian) is a stronghold in the northern Šilainiai elderate of the Lithuanian city of Kaunas, making a part of the Kaunas Fortress, constructed in the late 19th century. When the city was controlled by the Soviets, the stronghold was used as a prison and way-station for prisoners being transported to the Gulag. After the Nazis occupied the area, they used the fort as their place of execution for Jews, captured Soviets, and others. History Prison cell. Through this door, 64 prisoners escaped on 25 December 1943. At the end of 19th century, the city of Kaunas was fortified, and by 1890 it was encircled by eight forts and nine gun batteries. The construction of the Ninth Fort (its numerical designation having stuck as a proper noun) began in 1902 and was completed on the eve of the First World War. From 1924-on, the Ninth Fort was used as the city of Kaunas' prison. During the years of Soviet occupation, 1940-1941, the Ninth Fort was used by the NKVD to house political prisoners on their way to the gulags of Siberia. During the years of Nazi occupation, the Ninth Fort was put to use as a place of mass murder. At least 5,000 Lithuanian Jews of Kaunas, largely taken from the city's Jewish ghetto, were transported to the Ninth Fort and killed. In addition, Jews from as far as France, Austria and Germany were brought to Kaunas during the course of Nazi occupation and executed in the Ninth Fort. In 1944, as the Soviets moved in, the Germans liquidated the ghetto and what had by then come to be known as the "Fort of Death", and the prisoners were dispersed to other camps. After the Second World War, the Soviets again used the Ninth Fort as a prison for several years. From 1948 to 1958, farm organizations were run out of the Ninth Fort. In 1958, a museum was established in the Ninth Fort. In 1959, a first exposition was prepared in four cells telling about Nazi war crimes carried out throughout Lithuania. In 1960, the discovery, cataloguing, and forensic investigation of local mass murder sites began in an effort to gain knowledge regarding the scope of these crimes. Museum The Ninth Fort museum contains collections of historical artifacts related both to Soviet atrocities and the Nazi genocide, as well as materials related to the earlier history of Kaunas and Ninth Fort. The memorial to the victims of fascism at Ninth Fort in Kaunas, Lithuania, was designed by sculptor A. Ambraziunas. Erected in 1984, the monument is 105 feet (32 m) high. The mass burial place of the victims of the massacres carried out in the fort is a grass field, marked by a simple yet frankly worded memorial written in several languages. It reads, "This is the place where Nazis and their assistants killed more than 30,000 Jews from Lithuania and other European countries."

7,711 | Louis_Aleman | Louis Aleman (c. 1390 - September 16 1450) was a French cardinal. He was born of a noble family at the castle of Arbent near Bugey. A relative was the Papal Chamberlain. He was successively bishop of Maguelonne (1418), archbishop of Arles (1423) and Cardinal Priest of S. Cecilia (1426). He was a prominent member of the council of Basel, and, together with Cardinal Julian Cesarini, led the party which maintained the supremacy of general councils over the pope's authority. In 1440 Aleman obtained the support of the emperor Sigismund and of the duke of Milan to his views, and proclaiming the deposition of Pope Eugene IV, placed the tiara upon the head of Amadeus VIII, Duke of Savoy (henceforward known as Antipope Felix V). Eugene retorted by excommunicating the antipope and depriving Aleman of all his ecclesiastical dignities. In order to make an end of the schism, Felix V finally abdicated on Aleman's advice, and Nicholas V, who had succeeded in 1447, restored the cardinal to all his honours and employed him as legate to Germany in 1449. On his return he retired to his diocese of Arles, where he devoted himself zealously to the instruction of his people. He died on September 16 1450, and was beatified by Pope Clement VII in 1527.

7,712 | Book_of_Proverbs | The Book of Proverbs is a book of the Hebrew Bible (the Christian Old Testament), included in the collected works known as the "Writings" or Ketuvim. Title The original Hebrew title of the book of Proverbs is "Míshlê Shlomoh" ("Proverbs of Solomon"). When translated into Greek and Latin, the title took on different forms. In the Greek Septuagint (LXX) the title became "paroimai paroimiae" ("Proverbs"). In the Latin vulgate the title was "proverbial", from which the English title of Proverbs is derived. Authorship The authorship of Proverbs has long been a matter of dispute. Solomon’s name appears in Proverbs 1:1, "The proverbs of Solomon the son of David, King of Israel." There are also references within Proverbs to Agur (30:1) and Lemuel (31:1) as authors distinct from Solomon. These names are missing in the Greek translation of the Septuagint. Medieval scholars used in the Vulgate the Hebrew rendering of these two verses, and in their eyes the words "Agur" and "Lemuel" were but symbolical names of Solomon. Dean, Matt (1913). "Book of Proverbs". Catholic Encyclopedia. http://www.newadvent.org/cathen/12505b.htm Solomon is often mentioned as someone who has extensive wisdom in the Bible as well as in extra-biblical literature. However at the time of composition it was often the custom to place the name of the King or someone of prominence in writings in order to honor them, or to give those writings more prestige. In 1 Kings 4:29-34, 3000 proverbs and over 1000 songs are said to have come from Solomon and it is also said that people came from all over to hear the wisdom of Solomon. The general assumption is that Solomon was a part of the authorship to some extent, but that the book was not solely his work. Not only are the names "Agur" and "Lemuel" linked to other sections of the book, there are elements of disunity within the book that suggest more than one author. Some of the authorship is attributed to "Men of Hezekiah" (25:1), though it is stated that they simply transcribed the proverbs rather than writing them of their own accord. In terms of the text itself there are at least eight specific instances where authorship is mentioned: ProverbsAuthors/Collectors 1:1 Solomon 10:1 Solomon 25:1 Solomon (as copied by Hezekiah’s men) 30:1 Agur son of Jakeh 31:1 Lemuel (or his mother) 31:10-31 author unstated As for the eighth section there are scholars who consider the poem at the end of the book vs. 10-31 as written by an unknown author. The attributions of authorship are as follows in accordance with the scriptures above; Solomon, Solomon, Wise Men, Wise Men, Solomon (as copied by Hezekiah’s men), Agur son of Jakeh, Lemuel (or his mother), and the unknown author. With this possibility it is speculated that the sections written by the Wise Men were studied by Solomon and added in and that they influenced his writing. With this possibility it is likely that there would be similarities in the section written by Solomon as well as the sections by the Wise Men. Studies of word usage have indicated that the highest percentage of commonalities are between the three Solomon sections. The next most common are the Wise Men sections, showing that they could have influenced Solomon’s writing, and the least commonalities were with the Agur, Lemuel, and the unknown author. A majority of critical scholars, including James L. Crenshaw, Roland E. Murphy and L.G. Perdue, hold to the belief that much of Proverbs was brought together from a time well after Solomon. However, many well respected theologians continue to attribute most of the book to Solomon, including J. I. Packer, John Piper, John F. MacArthur, and Albert Mohler. Influences There have been suggestions that there is a crossover of some Egyptian nature in the proverbs from The Instructions of Amenemopet. ”Ancient Egyptian Literature, Volume II: The New Kingdom”, p146-163, Miriam Lichtheim, University of California Press, 1976, ISBN 0-520-03615-8 Proverbs as wisdom literature The book of Proverbs is referred to as wisdom literature along with several others: the book of Job, Ecclesiastes, the Song of Solomon, and certain Psalms, known as wisdom psalms. Among the deuterocanonical books, Ecclesiasticus and the Wisdom of Solomon are wisdom literature. Daily Study Many people use Proverbs as a daily study and guide to increase their wisdom and understanding. There are 31 chapters to Proverbs so reading one chapter a day, allows readers to complete the book of Proverbs in one month, but it is common for people to continue to read one chapter a day as part of their daily routine. There are many resources available like Daily Audio Bible which covers a chapter of Proverbs every day. Readings are available online, through iTunes, and MP3s. A Daily Proverb selects one verse a day from each chapter and are made available online, through twitter, facebook, and RSS. Setting It is difficult to pin the provenance of Proverbs down. Several suggestions have been made. Family In the society of ancient Israel, the family played an important role in the upbringing and education of children. Some internal evidence hints to the use of Proverbs in a family setting; the phrase "my son" appears some 20 times throughout the book. The role of the mother is also listed some 10 times. Court The name of Solomon stands in the title of the book, thus suggesting a royal setting. Throughout the Old Testament, wisdom is connected with the court. School It is possible practical and reflective wisdom was transmitted in a house of learning or instruction. W. Dennis Tucker, "Literary Forms in the Wisdom Literature" In: An introduction to Wisdom Literature and the Psalms, FS Marvin E. Tate, ed. H. Wayne Ballard, 163-166 Messianic interpretations in Christianity There are found in Proverbs, and other wisdom literature, references to Wisdom as a personification. These have long been taken by Christian exegetes as references to Christ, who is called the wisdom of God by Paul the Apostle. The first time Wisdom is personified is at Prov 1.20. In all these passages Wisdom is spoken of as a woman because the Hebrew word for “wisdom” is itself feminine; thus there is no problem associated feminine-personified Wisdom with the male Messiah. Wade Johnston, Proverbs 8, 2004, 4. The King James Bible reads, in reference to wisdom, that "The LORD possessed me in the beginning of his way, before his works of old." The LORD possessed wisdom and it, or she, was with him from the beginning. She was with him to create what has been created. However some apparently claim that Prov 8:22 was a crucial verse in the Arian controversies of the fourth century. The RSV ??? reads “The LORD created me at the beginning of his work, the first of his acts of old.” Proverbs 8 has long been taken to refer to Christ, so whether or not the Hebrew qanah should be taken as created or as possessed was used in the debate over the eternity of Christ. Both these meanings are used in the Old Testament, but created is never the sole possible meaning. Derek Kidner, The Proverbs, (Downer Grove: InterVarsity Press, 1976), 79. Kidner goes on to point out that it is absurd to think that God would need to create Wisdom, implying there was a time when he lacked Wisdom. Also, “Prov 8 starts from the indisputable commonplace that God existed before the start of time and ascribes the same precedence to wisdom.” Michael Fox, Proverbs 1-9: The Anchor Bible, (New York: Doubleday, 2000), 284. The remainder of Prov 8 shows Wisdom taking a role in creation, and contrasts Wisdom with created things. It is therefore best to take qanah to mean “possessed”; and Wisdom not as a creature. It has been noted that Col 1:15-16 is dependent on this chapter of Proverbs. Ibid., 279. The parallels in the roles of Christ and Wisdom lend credence to understanding qanah as possessed rather than created. We are told that Wisdom was, before the Lord made even a particle of matter (verse 26) or gave order to creation (verse 29); Wisdom participated in the creation story. This strongly parallels the role of Christ in Colossians, where he is the “first-born of all creation” and in him were all things created. To add to the identification of Wisdom with Christ, we find that Wisdom was identified with the Greek concept of logos, which was in turn identified with Christ. Ibid., 293.

7,713 | Musical_saw | Playing a musical saw A musical saw, also called a singing saw, is the application of a hand saw as a musical instrument. The sound created is an ethereal tone, very similar to the theremin, or a woman's clear voice. The musical saw is classified as an idiophone under the Hornbostel-Sachs system of musical instrument classification. The saw is generally played seated with the handle squeezed between the legs, and the far end held with one hand. It is generally played with the teeth facing the body, though some more timid players opt to face them away. Some sawists choose to play standing, either with the handle between the knees and the blade sticking out in front of them, or with the handle under the chin (like a violin). To make a note, a sawist first bends the blade into an S-curve. The parts of the blade that are curved are dampened from vibration, and do not sound. At the center of the S-curve a section of the blade remains relatively flat: this "sweet spot" can vibrate across the width of the blade, producing a distinct pitch (the wider the section of blade, the lower the sound). Sound can be created by drawing a bow across the back edge of the saw at the sweet spot, or by striking the sweet spot with a mallet. Harmonics can be heard by playing at varying distances on either side of the sweet spot. The sawist controls the pitch by adjusting the S-curve, making the sweet spot travel up the blade (toward a thinner width) for a higher pitch, or toward the handle for a lower pitch. Sawists can add vibrato by shaking one of their legs, or wobbling the hand that holds the tip of the blade. Once a sound is produced, it will sustain for quite a while, and can be carried through several notes of a phrase. Standard wood-cutting saws are often used by professional sawyers, although special musical saws are also made. The blades of these musical saws are generally wider (for range) and longer (for finer control), do not have set or sharpened teeth, and may have grain running parallel to the back edge of the saw, instead of parallel to the teeth. Some saws are made with thinner metal to increase flexibility, while thicker musical saws have a richer tone, longer sustain, and stronger "harmonics." A typical saw is 5" wide at the handle end, 1" wide at the tip, and will produce about 2 octaves (regardless of length). A "bass" saw may be 6" at the handle and will have about 2 1/2 octaves. Two-person saws, or "misery whips," can also be played, though with much less virtuosity, and an octave or less of range. Most sawyers use cello or violin bows, using violin rosin, but improvised home-made bows, such as a wooden dowel, are not uncommon. Musical saws have been produced for over a century. In the early 1900s there were at least ten companies in the United States alone manufacturing saws. These saws ranged from the familiar steel variety to gold-plated masterpieces worth hundreds of dollars. However, with the start of World War II the demand for metals made the manufacture of saws too expensive and many of these companies went out of business. In the year 2000 only three companies in the U.S. were making saws: Mussehl & Westphal, Charlie Blacklock, and Wentworth. Two other important companies exist in the saw world: Swedish Sandvik, maker of the Stradivarius saw and a company in France which produces a toothless saw, "La Lame Sonore," with a range of three octaves. An International Saw Competition is held every August in Felton, California. An International Musical Saw Festival is held every summer in NYC. Famous Musicians A performer Marlene Dietrich, A famous performer on the musical saw who first played it on the Berlin stage and later used it to entertain troops during World War II. Jack Robinson,famous musical saw player in England during the first half of the 20th century. Robinson was born in 1897 in Blackpool, but then moved to Liverpool and Edge Lane in the 1920s. He died in 1943. During his career he played with Harry Wood’s Grand Band at The Palace in Douglas, Isle of Man and Bert Pearson’s Band at Reece’s Ballroom in Liverpool. Jack also performed solo in a concert for charities including the Seamen’s Orphanage, Liverpool, held on board the RMS Duchess of York. He was also a professional hairdresser. You can see his bow and saw at the Museum of Liverpool Life, Liverpool, UK. Natalia Paruz, also known as the 'Saw Lady', plays the musical saw in movie soundtracks, TV commercials, with orchestras all over the world and in the New York City subway. November 2007 marked her Carnegie Hall debut as a musical saw soloist and June 2008 marked her Madison Square Garden debut. She is the organizer of the Musical Saw Festivals in NYC and in Israel and she was a judge at the International Musical Saw Competition in France. Her saw playing is mentioned in 4 books and has been featured in paintings by many artists. She has premiered music by many composers, including PDQ Bach. Kev Hopper, formally the bass guitarist in 1980's band, Stump, made an album entitled 'Saurus' in 2003 featuring six original saw tunes. Filmmaker Terry Zwigoff plays the musical saw with R. Crumb & His Cheap Suit Serenaders in addition to the cello, Stroh fiddle, and mandolin. The Yorkshire Musical Saw Player Charles Hindmarsh, also known as The Yorkshire Musical Saw Player is originally from Harrogate in England. Although he works in IT for Harrogate Borough Council, he has played the musical saw throughout the UK. While study violin at College the musical saw became a bit of a party trick. However this developed and he is now involved with playing for old time musical hall events, charity concerts and sessions as a soloist and/or with accompaniment from either piano or brass band. As well as taking part in the "BBC music live" festival he has also played in a skip outside Belfast City Hall for a "Catalyst Arts" Festival, in a folk festival at Broadstairs and as part of the International Gilbert and Sullivan festival in Buxton. He is now actively involved in promoting the playing of this wonderful instrument through workshops and public concerts. David Weiss- The retired Principal Oboe of the Los Angeles Philharmonic. What started out as a lark twenty-two years ago, David Weiss is now considered to be one of the world's foremost musical saw virtuosos. He has appeared on the Tonight Show, Prairie Home Companion, at Disneyland, on television commercials, and movies (most recently in the Grammy Award winning "O Brother Where Art Thou?"). July 1985 marked his Hollywood Bowl debut on the musical saw in a work specially commissioned for him by the Philharmonic. Larry Lipkis's "Harlequin" for bass trombone and orchestra features a prominent musical saw part which was played by Weiss at the composition's world premiere performances with Jeffrey Reynolds on bass trombone and Esa-Pekka Salonen conducting the Los Angeles Philharmonic. Other performances took place at Lincoln Center's Alice Tully Hall, aboard the QE2 and other cruises, and as an added feature in most of his oboe recitals. His album "Virtuoso Saw" received international critical acclaim. Robert Minden, a Canadian saw player who has been touring and recording since the early 1980s, learned from folk musician Thomas Jefferson Scribner on the streets of Santa Cruz California. Scribner referred to the forgotten voice of the saw as The Lost Sound". There is a statue honoring Scribner playing the saw in Santa Cruz. (see Lostsound.com for a picture of the statue) Akira Ifukube used musical saws often in his film scores. Julian Koster of Neutral Milk Hotel played the singing saw, along with various other instruments, in the band and currently plays the saw in his solo project, The Music Tapes. In 2008, he released The Singing Saw at Christmastime, an album of Christmas carols played on the saw. Eels occasionally use the singing saw in their live performances and recordings. In particular, on their Eels with Strings: Live at Town Hall live album, singing saws are notably heard during the musical interlude between "Flyswatter" and "Novocaine For The Soul". Mike Waldeck plays the musical saw with the eclectic band QIET. Emmanuel Brun was the famous french musical saw player. He met Yehudi Menuhin and Georggi Cziffra. He died in 2004. He was the teacher of Karine Safar. Bob Pritikin, San Francisco socialite, often performs classical music on the musical saw at eccentric parties in his mansion. Karine Safar plays with the pianist of Emmanuel Brun, Paule Sagne, in concerts. Artist Laurel Hausler plays the musical saw, sometimes accompanying puppet shows. The Olivia Tremor Control frequently uses the Musical saw. Pascal Ayerbe, the french composer and performer plays a Jacques Keller reissue model. Pat Phillips, the conductor of british Tapton Youth Brass Band Also: The main character on the movie Delicatessen plays a musical saw at several parts of the movie. Tom Waits uses the musical saw on many of his songs from the last 30 years Icelandic quartet Amiina plays a saw on stage, and indie-rock band The Black Heart Procession features the musical saw in many of their songs. Another Athens, GA band, Hope for Agoldensummer used the singing saw on recordings and in concert. Mercury Rev make extensive use of the saw on their albums Deserter's Songs and All Is Dream. Christina Marrs of the group Asylum Street Spankers plays the musical saw in numerous pieces, including 'The Minor Waltz'. Sarah McLachlan is one of the few mainstream artists to use a musical saw, as a main instrument on the composition 'Last Dance', featured on her 1997 album Surfacing. She does however not play the saw herself. Modern Rock band KoRn utilized a musical saw in their 2007 "Unplugged" performance, particularly during "Coming Undone". Experimental Indie pop band Br'er uses a singing saw on their single "Endomitriosis". An uncredited street musician plays the saw on the choruses of the Supertramp song "Hide in Your Shell", from their 1974 Crime of the Century album. Norwegian duo Thinguma*jigSaw, who are categorised under the self coined genre splatterfolk, use the saw as a vital element of their music as can be heard in their debut album 'Awake in Whitechapel'. A musical saw can be heard in The Devil Makes Three's song "River Deep" off their second album Longjohns, Boots and a Belt. A musical saw is played by Nicholas Brancaccio in the low-fi band Coors Light.

Mexican songwriter Julieta Venegas used the musical saw in the song "Como Se" for her MTV Unplugged performance. English band Keane featured the musical saw on their song "Love Is the End", and as a consequence they do not normally perform this song live: extra musicians were needed to record musical saw tracks because no member of the band is able to play the saw. However, Keane did perform it live with a guest sawist as part of their acoustic set in their 2008 Little Noise Session at Union Chapel, where lead singer Tom Chaplin described the musical saw as "the weirdest and most wonderful sound that we've ever experienced in our lives". Jess Hoffa of Broken Hips out of Richmond Virginia played a Mussehl and Westphall as well as a Sandvik Stradivarius saw live and in studio Sound of Music. She also played on various other recordings including Nina Persson's (of The Cardigans) A Camp and the Daniel Johnston album produced by Mark Linkous. Heard she's working on an album for 2009, but don't know if it will include saw. The prominent film composer Hans Zimmer used the musical saw in his score for Pirates of The Caribbean - At World's End. He contemplated several unique and interesting instruments, when a new, 'otherworldly' sound experience was needed to convey and depict a journey to distant lands.

7,714 | Nitrogen_narcosis | Narcosis while diving (nitrogen narcosis, inert gas narcosis, raptures of the deep, Martini effect) is a reversible alteration in consciousness that occurs whilst scuba diving at depth. It produces a state similar to alcohol intoxication or nitrous oxide inhalation. It can occur during shallow dives, but usually does not become noticeable until greater depths, beyond . Brubakk and Neuman p.301. Apart from helium, all gases that can be breathed have a narcotic effect, which is greater as the lipid solubility of the gas increases. As depth increases, the effects may become hazardous as the diver is increasingly impaired. Although divers can learn to cope with the effects, it is not possible to develop a tolerance. Predicting the depth at which narcosis will affect a diver is difficult as susceptibility varies widely from dive to dive and amongst individuals. The effects are completely reversed by ascending to a shallower depth with no long-term consequences. For this reason, narcosis while diving in open water rarely develops into a serious problem as long as the divers are aware of its symptoms and ascend to manage it. Diving beyond is considered outside the scope of recreational diving; as oxygen toxicity becomes a critical factor, specialist training is required in the use of various gas mixtures such as trimix or heliox. Classification Narcosis results from breathing gases under elevated pressure and may be classified by the principal gas involved. All of the noble gases, except helium, as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely, while the effects of carbon dioxide consistently result in decreased mental and psychomotor function. The noble gases argon, krypton, and xenon are more narcotic than nitrogen at a given pressure, and xenon has so much anesthetic activity that it is actually a usable anaesthetic at 80% concentration and normal atmospheric pressure. Xenon has historically been too expensive to be used very much in practice, but it has been successfully used for surgical operations, and xenon anesthesia systems are still being proposed and designed. Signs and symptoms Impression of narcosis-induced tunnel vision when reading gauges Due to its perception-altering effects, the onset of narcosis may be hard to recognize. page 3-40, section 3‑9.1 At its most benign, narcosis results in relief of anxiety and a feeling of tranquillity and mastery of the environment. These effects are similar to both alcohol and familiar benzodiazepine drugs such as Valium (diazepam) and Xanax (alprazolam). Such effects are not harmful unless they cause some immediate danger to not be recognized and addressed. An early effect may be loss of near-visual accommodation, causing increased difficulty in close-accommodation reading of small numbers in middle-aged or older divers who already have any degree of presbyopia. The most dangerous aspects of narcosis are the loss of decision-making ability, loss of focus, impaired judgement and multi-tasking and coordination. Other effects include vertigo, tingling and numbness of the lips, mouth and fingers, and exhaustion. The syndrome may cause exhilaration, giddiness, extreme anxiety, depression, or paranoia, depending on the individual diver and the diver's medical or personal history. When more serious the diver may begin to feel invulnerable, disregarding normal safe diving practices. Paradoxically, badly affected divers may panic, sometimes remaining on the bottom, too exhausted to ascend. The relation of depth to narcosis is sometimes informally known as "Martini's law". This is the idea that narcosis results in the feeling of one martini for every 10 meters below 20 meters depth (30 feet below 60 foots depth). This is a very rough guide, and not a substitute for an individual diver's known susceptibility, or for standard diving safety guides. Professional divers use such a calculation only as a rough guide to give new divers a metaphor for a situation they may be more familiar with. Reported signs and symptoms are summarized against typical depths in metres and feet of sea water in the following table: + Signs and symptoms of narcosis (breathing air)Depth (msw)Depth (fsw) Comments10–30 33–100 Mild impairment of performance of unpracticed tasks.Mildly impaired reasoning.Mild euphoria possible.30–50 100–165 Delayed response to visual and auditory stimuli.Reasoning and immediate memory affected more than motor co-ordination.Calculation errors and wrong choices.Idea fixation.Over-confidence and sense of well-being.Laughter and loquacity (in chambers) which may be overcome by self control.Anxiety (common in cold murky water).50–70 165–230 Sleepiness, impaired judgment, confusion.Hallucinations.Severe delay in response to signals, instructions and other stimuli.Occasional dizziness.Uncontrolled laughter, hysteria (in chamber).Terror in some.70–90 230–300 Poor concentration and mental confusion.Stupefaction with some decrease in dexterity and judgement.Loss of memory, increased excitability.90+ 300+ Hallucinations.Increased intensity of vision and hearing.Sense of impending blackout, euphoria, dizziness, manic or depressive states, a sense of levitation, disorganization of the sense of time, changes in facial appearance.Unconsciousness. Death. Causes The cause of narcosis is related to the increased solubility of gases in body tissues, as a result of the elevated pressures at depth (Henry's law). Brubakk and Neuman p.308. Modern theories have suggested that inert gases dissolving in the lipid bilayer of cell membranes cause narcosis. More recently, researchers have been looking at neurotransmitter receptor protein mechanisms as a possible cause of the narcosis. The breathing gas mix entering the diver's lungs will have the same pressure as the surrounding water, known as the ambient pressure. For any given depth, the pressure of gases in the blood passing through the brain catches up with ambient pressure within a minute or two and this produces a delay in narcotic effect after coming to a new depth. Rapid compression potentiates narcosis, owing to carbon dioxide retention. Brubakk and Neuman p.303. A divers' cognition may be affected on dives as shallow as , but the changes are not usually noticeable. However there is no reliable method to predict the depth at which narcosis becomes noticeable, or the severity of the effect on an individual diver, as the effect may vary from dive to dive (even on the same day). Significant impairment due to narcosis is an increasing risk below depths of about , corresponding to an ambient pressure of about . Most sport scuba training organizations recommend depths of no more than because of risk of narcosis. When breathing air at depths of —an ambient pressure of about —narcosis in most divers leads to hallucinations, loss of memory, and unconsciousness. A number of divers have died in attempts to set air depth records below ; because of these incidents the Guinness Book of World Records no longer reports on this figure. Narcosis has been compared with altitude sickness insofar as its variability (though not its symptoms); its effects depend on many factors, with variations between individuals. Excellent cardiovascular health is no protection and poor health is not necessarily a predictor. Thermal cold, stress, heavy work, fatigue, and carbon dioxide retention all increase the risk and severity of narcosis. Narcosis is known to be additive to even minimal alcohol intoxication, and also to the effects of other drugs such as marijuana (which is more likely than alcohol to have effects which last into a day of abstinence from use). Other sedative and analgesic drugs, such as opiate narcotics and benzodiazepines, add to narcosis. Mechanism The precise mechanism is not well understood, but it appears to be a direct effect of gas dissolving into nerve membranes and causing temporary disruption in nerve transmissions. While the effect was first observed with nitrogen (in air), other gases including argon, krypton, and hydrogen also cause very similar effects under higher than atmospheric pressure. Brubakk and Neuman p.304. Some of these effects have been suggested as due to antagonism at NMDA receptors and potentiation of GABAA receptors, similar to the mechanism of nonpolar anesthetics such diethyl ether or ethylene. However, their reproduction by the very chemically inactive gas argon makes them unlikely to be a strictly "chemical" bonding to receptors in the usual sense of a chemical bond. An indirect physical effect (such as a change in membrane volume) would therefore be needed in some cases for a chemical effect on nerve cell ligand-gated ion channels. Trudell et al. have suggested non-chemical binding due to the attractive van der Waals force between proteins and inert gases. Similar to the mechanism of ethanol's effect, the increase of gas solubility in the nerve cell membrane may cause altered ion permeability properties of the neural cell's lipid bilayers. It has been found that the partial pressure of a gas required to cause a measured degree of impairment correlates well with the lipid solubility of the gas: the greater the solubility, the less partial pressure needed. An early theory, the Meyer-Overton hypothesis suggested that narcosis happens when the gas penetrates the lipids of the brain's nerve cells, causing direct mechanical interference with the transmission of signals from one nerve cell to another. More recently, specific types of chemically-gated receptors in nerve cells have been identified as being involved with anesthesia and narcosis, but the basic and most general underlying idea that nerve transmission is altered in many diffuse areas of the brain, as a result of presence of gas molecules dissolved in the nerve cell's fatty membranes, remains largely unchallenged. Diagnosis The symptoms described may be caused by other factors during a dive: ear problems causing disorientation or nausea; early signs of oxygen toxicity causing visual disturbances; hypothermia causing rapid breathing and shivering. Nevertheless the presence of any of these symptoms should imply narcosis. Alleviation of the effects upon ascending to a shallower depth will confirm the diagnosis. Given the setting, it is unlikely that other conditions would produce the reversible effects. In the rare event of misdiagnosis with another condition causing the symptoms, the initial management—ascending closer to the surface—is still required. Prevention Formal dive training stresses that deep dives can be made only after a gradual training to gradually test the individual diver's sensitivity to increasing depths, with careful supervision and logging of reactions. Diving organizations such as Global Underwater Explorers (GUE) are careful to emphasize that such sessions are for the purpose of gaining experience in recognizing the onset symptoms of narcosis for a given diver (which tend to be somewhat more repeatable than for the average group of divers, just as is the case with symptoms of intoxication with alcohol). At the same time, GUE stresses that there is little scientific evidence that a diver can "train" to overcome any measure of narcosis at a given depth or become tolerant of it. While the individual diver cannot predict exactly at what depth the onset of narcosis will occur on a given day, the first symptoms of narcosis for any given diver are often more predictable and personal. For example, one diver may have trouble with eye focus (close accommodation for middle-aged divers), another may experience feelings of euphoria, and another feelings of claustrophobia. Some divers report that they have hearing changes, and that the sound which their exhaled bubbles make becomes different. Specialist training may help divers in identifying these personal onset signs, and these may then be used as a signal to ascend to shallower depths. Although it is sometimes true that narcosis interferes with judgement to prevent such decisions, this is by no means always the case. The most straightforward way to avoid nitrogen narcosis is for a diver to limit the depth of dives. If narcosis does occur, the effects disappear almost immediately upon ascending to a shallower depth. As narcosis gets worse with increasing depth, a diver keeping to shallower depths can avoid serious narcosis. Most recreational dive schools will only certify basic divers to depths of , and at these depths narcosis does not present a large risk. Further training is normally required for certification up to on air, and this training should include a discussion of narcosis, its effects, and cure. Some diver training agencies offer speciality training to prepare recreational divers to go to depths of , often consisting of further theory and some practice in deep dives with close supervision. A number of technical diving agencies, such as TDI and IANTD teach "extended range" or "deep air" courses which teach diving to depths of up to 180 feet (55 metres) without helium. Some diving organizations teach their divers to frequently check their mental state while immersed using the "thumbs test". The two companions regularly show each other their fingers. One shows a number of fingers (e.g. 2), and then the other must respond by showing back one more or one less (i.e. 3 or 1), depending on previous agreement. If either of them botches the arithmetic, they should suspect narcosis. Scuba organizations which train for depths beyond recreational depths, commonly considered depths greater than , tend to simply ban diving with gases that cause too high narcosis levels at depth in the average diver, and instead, to strongly encourage the use of other breathing gas mixes containing helium in place of some or all of the nitrogen in air, such as trimix and heliox because helium has no narcotic potential. Brubakk and Neuman p.305. The use of these gases forms part of technical diving and requires further training and certification. Equivalent narcotic depth (END) is a commonly used way of expressing the narcotic effect of different breathing gases. Standard tables, based on relative lipid solubilities, list conversion factors for narcotic effect. For example, neon at a given pressure has a narcotic effect equivalent to nitrogen at 0.28 times that pressure, so in principle it should be usable at nearly four times the depth. Argon, on the other hand, has 2.33 times the narcotic effect of nitrogen, and is not suitable as a breathing gas for diving (it is used as a drysuit inflation gas, owing to its low thermal conductivity). Some gases have other dangerous effects when breathed at pressure; for example, high-pressure oxygen can lead to oxygen toxicity. Although helium is the least intoxicating of the breathing gases, at greater depths it can cause high pressure nervous syndrome, a still-mysterious but apparently unrelated phenomenon. Inert gas narcosis is only one factor which influences the choice of gas mixture; the risk of decompression sickness and oxygen toxicity, cost, and other factors are also important. Because of similar and additive effects, divers should avoid sedating medications and drugs, such as marijuana and alcohol before any dive. A hangover, combined with the reduced physical capacity that goes with it, makes nitrogen narcosis more likely. Experts recommend total abstinence from alcohol at least 24 hours before diving, and longer for heavy drinking. Abstinence time needed for marijuana is unknown, but due to the much longer half-life of the active agent of this drug in the body, it is likely to be longer than for alcohol. Management The management of narcosis is to ascend to shallower depths; the effects then disappear within minutes. In the event of complications or other conditions being present, ascending is always the correct initial response. Should problems remain, then it is necessary to abort the dive. The decompression schedule can still be followed unless complications beyond the narcosis require emergency assistance. Prognosis Narcosis is potentially one of the most dangerous conditions to affect the scuba diver below about . Except for occasional amnesia of events at depth, the effects of narcosis are entirely reversible by ascending and therefore pose no problem in themselves, even for repeated, chronic or acute exposure. Nevertheless, the severity of narcosis is unpredictable and it can be fatal while diving, as the result of illogical behaviour in a dangerous environment. Epidemiology Tests have shown that all divers are affected by nitrogen narcosis, though some are less affected than others. Even though it is possible that some divers can manage better than others because of training (learning) to cope with impairment, the underlying effects remain. These effects are particularly dangerous because a diver may subjectively feel they are not experiencing narcosis, yet still be affected by it. History French researcher Victor T. Junod was the first to describe symptoms of narcosis in 1834, noting "the functions of the brain are activated, imagination is lively, thoughts have a peculiar charm and, in some persons, symptoms of intoxication are present." Brubakk and Neuman p.300. Junod suggested that narcosis resulted from pressure causing increased blood flow and hence stimulating nerve centers. Brubakk and Neuman p.306. Walter Moxon (1836–1886), a prominent Victorian physician, hypothesised in 1881 that pressure forced blood to inaccessible parts of the body and the stagnant blood then resulted in emotional changes. The first report of anaesthetic potency being related to lipid solubility was published by H. H. Meyer in 1899, entitled Zur Theorie der Alkoholnarkose. Two years later a similar theory was published independently by Charles Ernest Overton. In 1939, Behnke and Yarborough demonstrated that gases other than nitrogen also could cause narcosis. For an inert gases the narcotic potency was found to be proportional to its lipid solubility. As hydrogen has only 0.55 the solubility of nitrogen, deep diving experiments using hydrox were conducted by Arne Zetterström between 1943 and 1945. Jacques Cousteau in 1953 famously described it as "l’ivresse des grandes profondeurs" or the "rapture of the deep". Further research into the possible mechanisms of narcosis by anesthetic action led to the "minimum alveolar concentration" concept in 1965. This measures the relative concentration of different gases required to prevent motor response in 50% of subjects in response to stimulus, and shows similar results for anesthetic potency as the measurements of lipid solubility. The National Oceanic and Atmospheric Administration (NOAA) Diving Manual was revised to recommend treating oxygen as if it were as narcotic as nitrogen, following research by Lambertsen et al. in 1977 and 1978.

7,715 | Gavrilo_Princip | Gavrilo Princip (Cyrillic: Гаврило Принцип, ; – ) was a Serbian nationalist associated with the freedom movement Mlada Bosna. http://books.google.com/books?id=Cvk6oMf9R7AC&pg=PA153&lpg=PA153 Princip assassinated Archduke Franz Ferdinand of Austria and his wife in Sarajevo on 28 June 1914. Princip and his accomplices were arrested and implicated a number of members of the Serbian Military, leading Austria-Hungary to issue a démarche to Serbia known as the July Ultimatum. This set off a chain of events that led to World War I. http://books.google.com/books?id=rUMM_-Q7JDAC&pg=PA9 Early life Gavrilo Princip was born in the village of Obljaj, near Bosansko Grahovo, Bosnia and Herzegovina, Austria-Hungarian Empire, the son of a postman. His parents, Petar and Marija (née Mićić), had nine children, five sons and four daughters, six of whom died in infancy. Gavrilo's health was poor from an early age and it was further aggravated by his living conditions. His impoverished parents could not provide for him and sent him to live with an older brother in Zagreb. Most historians agree that Princip was a member of Young Bosnia; that the group got its weapons from the Black Hand (Црна рука/Crna ruka); and that the latter group was at least somewhat responsible for coordination, training, and/or supplying weapons for the forthcoming assassination attempt on Franz Ferdinand. However, Princip had minimal contact with the group, and did not associate with them. The Young Bosnia movement was a group made up of Serbs, committed to the independence of the South Slavic peoples from Austria-Hungary. In February 1912, Princip took part in protest demonstrations against the Sarajevo authorities for which he was expelled from school. Following his expulsion, he moved to Belgrade. In Belgrade, he sought to gain admission to the First Belgrade Gymnasium but failed the entrance exam. On 6 October 1908, Bosnia-Herzegovina was declared a part of the Austro-Hungarian Empire by Emperor Franz Josef. This created a stir among Slavic people of southern Europe and the Russian Czar who opposed this annexation. In 1912, Serbia was abuzz with mobilization for the First Balkan War. Princip planned to join the komite, irregular Serbian guerrilla forces under Serbian Major Vojislav Tankosić which had fought in Macedonia against Ottoman units. Tankosić was a member of the central committee of the secret society Unification or Death (Ujedinjenje ili Smrt). Princip, however, was rejected by the komite in Belgrade because of his small physical stature. He then went to Prokuplje in Southern Serbia where he sought a personal interview with Tankosić. Tankosić, however, rejected Princip due to being "too small and too weak." Vladimir Dedijer argued that this rejection was "one of the primary personal motives which pushed him to do something exceptionally brave in order to prove to others that he was their equal." Assassination of the Archduke Franz Ferdinand On 28 June 1914 Gavrilo Princip participated in the assassination in Sarajevo. General Oskar Potiorek, Governor of the Austrian provinces of Bosnia and Herzegovina had invited Franz Ferdinand and Countess Sophie to watch his troops on manoeuvres. Franz Ferdinand knew that the visit would be dangerous, knowing his uncle, Emperor Franz Josef, had been the subject of an assassination attempt by the Black Hand in 1911. Just before 10 o'clock on Sunday, the royal couple arrived in Sarajevo by train. In the front car was Fehim Čurčić, the Mayor of Sarajevo and Dr. Gerde, the city's Commissioner of Police. Franz Ferdinand and Sophie were in the second car with Oskar Potiorek and Count Friedrich August von Harrach-Rohrau. The car's top was rolled back in order to allow the crowds a good view of its occupants. The seven conspirators lined the route. They were spaced out along the Appel Quay, each one with instructions to try to kill Franz Ferdinand when the royal car reached his position. The first conspirator on the route to see the royal car was Bosniak Muhamed Mehmedbašić. Standing by the Austro-Hungarian Bank, Mehmedbašić lost his nerve and allowed the car pass without taking action. Mehmedbašić later said that a policeman was standing behind him and feared he would be arrested before he had a chance to throw his bomb. At 10:15 A.M., when the six car procession passed the central police station, nineteen-year-old student Nedeljko Čabrinović hurled a hand grenade at the Archduke's car. The driver accelerated when he saw the object flying towards him, but the bomb had a 10 second delay and exploded under the wheel of the next car. Two of the occupants, Eric von Merizzi and Count Ludwig Joseph von Boos-Waldeck were seriously wounded. About a dozen spectators were also hit by bomb splinters. After Čabrinović's bomb missed the Archduke's car, five other conspirators, including Princip, lost an opportunity to attack because of the heavy crowds and the high speed of the Archduke's car. To avoid capture, Čabrinović swallowed cyanide and jumped into the River Miljacka to make sure he died. The cyanide pill was very old and made him sick, but failed to kill him and the River Miljacka was only deep. A few seconds later he was hauled out and detained by police. Franz Ferdinand later decided to go to the hospital and visit the victims of Čabrinović's failed bombing attempt. In order to avoid the city centre, General Oskar Potiorek decided that the royal car should travel straight along the Appel Quay to the Sarajevo Hospital. However, Potiorek forgot to inform the driver, Leopold Loyka, about this decision. On the way to the hospital, Loyka took a right turn into Franz Josef Street. Princip had gone into Moritz Schiller's cafe for a sandwich, having apparently given up, when he spotted Franz Ferdinand's car as it drove past, having taken the wrong turn. After realizing the mistake, the driver put his foot on the brake, and began to back up. In doing so the engine of the car stalled and the gears locked, giving Princip his shot. Princip stepped forward, drew his FN Model 1910 pistol, and at a distance of about five feet, fired twice into the car. Franz Ferdinand was hit in the neck and Sophie in the abdomen, and they both died before 11:00 A.M. His partners in Archduke Ferdinand's death were: Nedjelko Čabrinović, Trifun Grabež, Muhamed Mehmedbašić, Vaso Čubrilović, Cvjetko Popović, Lazar Djukić, Danilo Ilić, Veljko Čubrilović, Neđo Kerović, Mihaijlo Jovanović, Jakov Milović, Mitar Kerović, Ivo Kranjcević, Branko Zagorac, Marko Perin, and Cvijan Stjepanović. Capture and imprisonment Princip, second from right, arrested. Princip attempted suicide first by ingesting cyanide, and then with the use of his pistol. But he vomited the past-date poison (as did Čabrinović, leading the police to believe the group had been deceived and bought a much weaker poison). The pistol was wrestled from his hand before he had a chance to fire another shot. Princip was too young to receive the death penalty, being twenty-seven days short of his twentieth birthday at the time of the assassination. Instead, he received the maximum sentence of twenty years in prison. He was held in harsh conditions which were worsened by the war. He died of tuberculosis on 28 April 1918 at Theresienstadt (a place which later became infamous as a Nazi concentration camp). At the time of his death, Princip weighed around , weakened by malnutrition, blood loss, and disease. Gavrilo Princip's trial on 5 December 1914. The house where Gavrilo Princip lived in Sarajevo was destroyed during the First World War. After the war, it became a museum in the Kingdom of Yugoslavia. Yugoslavia was conquered by Germany in 1941 and Sarajevo became part of fascist Croatia. The Croatian fascists destroyed the house again. After a communist Yugoslavia was established in 1944, the house of Gavrilo Princip became a museum again and there was another museum dedicated to him within the city of Sarajevo. During the Yugoslav Wars of the 1990s, the house of Gavrilo Princip was destroyed a third time by the government; no attempts to rebuild it have yet been announced. The Gavrilo Princip museum has been turned into a museum dedicated to Archduke Ferdinand and the Habsburg monarchy. Prior to the 1990s the site on the pavement on which Princip stood to fire the fatal shots was marked by embossed footprints. These were removed as a consequence of the 1992-5 war in Bosnia and the perception of Princip as having been a Serb nationalist. Later, a simple wooden memorial was placed near the site of the assassination with the words "May Peace Prevail on Earth" in Bosnian, Serbian and English. Unwittingly, he is one of the most influential people in 20th century history, being indirectly responsible for sparking the chain of events that led to both World Wars.

7,716 | Old_Fashioned | The Old Fashioned is a cocktail, possibly the first drink to be called a cocktail. It is traditionally served in a short, round, 8–12 ounce tumbler-like glass, called an Old-Fashioned glass, named after the drink. The Old Fashioned is one of six basic drinks listed in David A. Embury's classic The Fine Art of Mixing Drinks. History The first documented definition of the word "cocktail" was in response to a reader's letter asking to define the word in the May 6, 1806 issue of The Balance and Columbia Repository in Hudson, New York. In the May 13, 1806 issue, the paper's editor wrote that it was a potent concoction of spirits, bitters, water, and sugar, a kind of bittered sling. "Raising a glass to the cocktail", Newsday article by Sylvia Carter, May 17, 2006. Newsday archive; Highbeam archive. Relevant paragraph quoted at ArtHistoryInfo.com Some claim the first use of the specific name "Old Fashioned" was for a Bourbon whiskey cocktail in the 1880s, at the Pendennis Club, a gentlemen’s club in Louisville, Kentucky. The recipe is said to have been invented by a bartender at that club, and popularized by a club member and bourbon distiller, Colonel James E. Pepper, who brought it to the Waldorf-Astoria Hotel bar in New York City. Others point out that the term was already in use before the Pendennis Club was founded. Recipe There is great contention on the proper way to make an Old Fashioned. Here is one recipe: 2 ounces (60 ml) bourbon Splash of simple syrup or 1 cube sugar and just enough water to dissolve the sugar 2 dashes bitters Old Fashioned glass Place sugar (or syrup), bitters, and water in old-fashioned glass Crush sugar if needed and coat glass Add 2–3 cubes ice and whiskey Garnish with twist An 1895 recipe specifies the following: Dissolve a small lump of sugar with a little water in a whiskey glass Add two dashes Angostura bitters Add a small piece of ice Add a piece lemon peel Add one jigger (1.5 ounces or 44 mL) whiskey Mix with small bar spoon and serve, leaving spoon in glass. Modifications In some areas, notably Wisconsin, brandy is substituted for whiskey (sometimes called a Brandy Old Fashioned). Many drinkers prefer to use rye whiskey because of its complexity. Most modern recipes top off an Old Fashioned cocktail with soda water. Purists decry this practice, and insist that soda water is never permitted in a true Old Fashioned cocktail. Many respected sources (e.g. Maker's Mark) list an Old Fashioned as containing soda water, forgoing the bitters altogether. Many bartenders add fruit, typically an orange slice, and muddle it with the sugar before adding the whiskey. This practice likely began during the Prohibition as a means of covering the bitter taste. Another explanation for the practice is that citrus is often used in place of bitters in areas where citrus fruit grows (such as Florida and California). Hence, the fresh San Diego old fashioned () uses limes, lemons, oranges, and soda water rather than bitters and simple syrup. The drink may have been imported to California during WWII, when many Midwestern and Southern boys moved to San Diego for the Navy. Purists advocate using just enough plain water (called "branch" water) to fully dissolve the sugar without diluting the whiskey, although many whiskey drinkers advocate diluting it by at least 50% to prevent the taste buds from becoming paralyzed by the high alcohol content. Bartenders often use a dissolved sugar-water premix called simple syrup, which is faster to use and eliminates the risk of leaving undissolved sugar in the drink, which can spoil a drinker's final sip. Others use only the juice of a maraschino cherry, along with the muddled and mangled cherry left at the bottom of the glass. One popular garnish is a maraschino cherry fastened to the back of an orange wedge using a toothpick. Others prefer to use orange zest with the maraschino cherry. See also List of cocktails. Notes References "Renewing an Old Fashion" by Robert Hess at DrinkBoy.com, discusses the history of this cocktail in detail, specifically focusing on the issue of whether to add soda water to the cocktail or not. "Nothing wrong with Old Fashioned values" Article from Issue 46 of Whisky Magazine, March 2005. "The brandy old-fashioned: Solving the mystery behind Wisconsin's real state drink" Article by Jerry Minnich from The Daily Page, Madison, Wisconsin newspaper. The article is no longer available at the paper's site, but archive.org has an accessible copy here. The Cole Porter song "Make it Another Old Fashioned, Please" (originally introduced by Ethel Merman in 1940's Panama Hattie) references the drink the Old Fashioned. "Are You Friends, After an Old Fashioned?", by Paul Clarke of the New York Times, discusses internet forum debates among "home cocktail enthusiasts," using the Old Fashioned as a focal point.

7,717 | Jedi | For other uses of this and similar words, see Jedi (disambiguation). Jedi Master Qui-Gon Jinn (right) and Padawan Obi-Wan Kenobi in Star Wars Episode I: The Phantom Menace In George Lucas's fictional Star Wars universe, the Jedi are an ancient monastic peacekeeping organization known for their observance of the Force, They specifically use the "Light Side" of the force and reject the "Dark Side" of the Force, as well as the Dark Side's adherents, the Sith. While various sources and ideas have been brought forth as the initial inspiration for the idea of a fictional "Jedi" order, the most apparent are the current and past chivalric orders that exist in Europe. It is speculated they were named after the jidaigeki genre of Japanese films about samurai. History and structure The Jedi initially formed at approximately the same time as the Old Republic, 25,000 years before the time frame of the movies. However, soon after its formation, several Jedi left the order to follow the path of the Dark Side, the first of many schisms. The Jedi Order was ruled by a board of 12 members called the Jedi Council, located on the planet of Coruscant before being destroyed by Emperor Palpatine. The council represented a gathering of great minds which acted as a governing body for the order as well as a martial advisory board for the Old Republic Senate. Expanded Universe Within the Expanded Universe of Star Wars media, the primary Jedi Council on Coruscant is the most dominant of a number of Jedi governing bodies. At one point approximately 4,000 years prior to the movies, there was also a Jedi council on Dantooine. After the events in Episode 6, Luke Skywalker eventually reestablishes the Jedi Order and creates something called the Masters' Council. During times of great danger, the Jedi engaged in direct democracy through massive gatherings called conclaves, at which they discussed issues and came to decisions. The Sith trace their roots back from heretical Jedi who followed the path of the Dark Side towards the homeworld of the Sith race. This Sith Empire invaded the Old Republic 5,000 years before the events of the movies in what was known as the Great Hyperspace War. Over time, the Dark Jedi and the Sith intermingled, until eventually the word Sith stopped referring to the race but rather the ideology of the Dark Jedi, and the Sith began to come from various races and planets united by the goal of eradicating the Jedi and the pursuit of power through the Dark Side. Jedi ranks Members of the order progress through four to six tiers of rank, at times referred to as levels. Jedi Youngling : A Jedi Youngling is a Jedi learning to control the force and how to wield a lightsaber. The title of Jedi Youngling is the first part of a Jedi training. Younglings were seen training with Jedi Grand Master Yoda in a scene from Star Wars: Episode II - Attack of the Clones. Jedi Padawan: A Youngling that successfully completes their respective level of training undergoes Padawan apprentice training under the tutelage of a Jedi Knight or Jedi Master. As a rite of passage and the final test before the trials to knighthood, Padawans must build their own lightsabers. In the Old Republic, male Human Padawans usually wore braids in their hair that were removed upon attaining knighthood. Jedi Knight: Disciplined, experienced Jedi may become full-fledged Jedi Knights once they have completed "the trials" that test candidates' skills, knowledge, and dedication. The three tests are usually known as The Trial of Skill, The Trial of Spirit, and the Trial of Knowledge. In Return Of The Jedi, Master Yoda gives his apprentice Luke Skywalker the trial of confronting Darth Vader for a second time so he might become a full-fledged Knight. Occasionally, performing an extraordinary (usually heroic) act can earn a Padawan learner Jedi Knight status, such as when Obi-Wan Kenobi defeats the Sith Apprentice Darth Maul. Or in the case of Anakin Skywalker who defeats Sith Apprentice Asaji Ventress. Jedi Master: A Jedi Knight may become a Jedi Master after successfully training a Padawan learner to Knight status. Though this is the most common manner, it is not always the case. If the council sees that a Jedi Knight has become more powerful and has gained more knowledge and discipline in the Force, then they can be nominated by one or more council members to take the trials again. Anakin Skywalker is briefly appointed the rank of Jedi Master for unkown reasons, however, he soon turns to the dark side, ironically relinquishing the title he worked so hard to attain. Jedi Council Member: When a Jedi Council Member vacates its seat, the council looks for an exemplary Jedi Master to fill the empty position. Presiding Council Members elect prospective candidates when openings become available. According to the Dorling Kindersley guide to Star Wars Episode I: The Phantom Menace, some members were permanent members (like Yoda and Mace Windu), while the rest served limited terms, after which they stepped down and another member would be elected to the Jedi Council. With the exceptions of Anakin Skywalker and Ki-Adi Mundi, who was the only Knight on the Council for a short period of time before becoming a Jedi Master, all council members require the status of Jedi Master prior to entering the council. Jedi Grand Master: Formally "Grand Master of the Jedi Order," only the highest-ranking Jedi Masters take the title. The title of Grand Master/Supreme Master is merely a theoretical title given by Jedi Masters to a certain Master who has been most wise among other masters in the council, as with Master Yoda. The Jedi Grand Master does not enjoy any greater privilege than any council members because the council members also have a vote in any issues presented by the council. The Grand Master was apparently the "first among equals" of the Jedi High Council, or the later Masters' Council. Yoda and Luke Skywalker (in the expanded universe) are Grand Masters. Equipment Within the Star Wars universe, the Jedi are usually portrayed as dressed in simple robes and carrying specialized field gear for their missions. The most notable instrument wielded by a Jedi is the lightsaber. Lightsabers are used by both Jedi and Sith. Jedi commonly wield blue and green lightsabers in the movies, while the Sith tend to wield red ones. Jedi Mace Windu (Samuel L. Jackson) and Siri Tachi (from Expanded Universe books) wield unique purple lightsabers. The former Jedi Padawan Ferus Olin, from Expanded Universe books, wielded a red blade. However, he was not a Sith. In the Expanded Universe of Star Wars media, there were a vast variety of lightsaber colors. In Knights Of The Old Republic, the colors signified the Jedi's specialization. Religion One of the enduring influences the Star Wars saga has had is the idea of the fictional Jedi values being interpreted in a modern philosophical path or religion. Over half a million people throughout the world declared themselves as Jedi on their census forms, which was considered to be a practical joke and may not reflect the real number of Jedi in the countries concerned. The Jedi hold a religious reverence to The Force, approached through meditation, civic service and learning similar to that of Buddhist monks, particularly those of the Shaolin Monastery.

Most of these stations broadcast various types of music format, and political discussions, news and phone-in programmes remain mostly the domain of the national broadcaster (NBC) which broadcasts nine radio services nationally (in various Namibian languages, including German - the only full-time German service outside of Germany), plus the new !Ha service, broadcasting to the San community in Tsumkwe. Television broadcast stations: 8 (plus about 20 low-power repeaters) (1997) The television network with the widest transmission range is NBC TV Namibian Broadcasting Corporation (NBC, not to be confused with the American NBC network). The NBC is the successor to the South Africa-run South West African Broadcasting Corporation (SWABC), which was modelled on the original SABC. Like the radio services of the NBC, the television service tries to cater to all the linguistic audiences in Namibia, although the dominant language is English (Namibia's official language) The commercial 'free to air' station is One Africa Television, the successor to the now defunct TV Africa. It has also expanded its transmitter network and is now available in most major towns and cities in Namibia. In 2007 it also commenced with broadcasting a local television news bulletin each evening. TBN (Trinity Broadcasting Network) is a religion television station, with some material originating locally, although also carrying relays from the United States. It is based in Windhoek and holds a community television licence.

7,719 | Argon | Cavendish's method for the isolation of Argon. The gases are contained in a test-tube (A) standing over a large quantity of weak alkali (B), and the current is conveyed in wires insulated by U-shaped glass tubes (CC) passing through the liquid and round the mouth of the test-tube. The inner platinum ends (DD) of the wire receive a current from a battery of five Grove cells and a Ruhmkorff coil of medium size. Argon () is a chemical element designated by the symbol Ar. Argon has atomic number 18 and is the third element in group 18 of the periodic table (noble gases). Argon is present in the Earth's atmosphere at 0.94%. Terrestrially, it is the most abundant and most frequently used of the noble gases. Argon's full outer shell makes it stable and resistant to bonding with other elements. Its triple point temperature of 83.8058 K is a defining fixed point in the International Temperature Scale of 1990. Characteristics A small piece of rapidly melting argon ice. Argon has approximately the same solubility in water as oxygen gas and is 2.5 times more soluble in water than nitrogen gas. Argon is colorless, odorless, tasteless and nontoxic in both its liquid and gaseous forms. Argon is inert under most conditions and forms no confirmed stable compounds at room temperature. Although argon is a noble gas, it has been found to have the capability of forming some compounds. For example, the creation of argon fluorohydride (HArF), a marginally stable compound of argon with fluorine and hydrogen, was reported by researchers at the University of Helsinki in 2000. Although the neutral ground-state chemical compounds of argon are presently limited to HArF, argon can form clathrates with water when atoms of it are trapped in a lattice of the water molecules. Also argon-containing ions and excited state complexes, such as ArH+ and ArF, respectively, are known to exist. Theoretical calculations have shown several argon compounds that should be stable but for which no synthesis routes are currently known. History Argon (Greek meaning "inactive", in reference to its chemical inactivity) was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay in Scotland in an experiment in which they removed all of the oxygen, carbon dioxide, water and nitrogen from a sample of clean air. They had determined that nitrogen produced from chemical compounds was one-half percent lighter than nitrogen from the atmosphere. The difference seemed insignificant, but it was important enough to attract their attention for many months. They concluded that there was another gas in the air mixed in with the nitrogen. Argon was also encountered in 1882 through independent research of Hugh Frank Newall and W.N. Hartley. Each observed new lines in the color spectrum of air but were unable to identify the element responsible for the lines. Argon became the first member of the noble gases to be discovered. The symbol for argon is now Ar, but up until 1957 it was A. Occurrence Argon constitutes 0.934% by volume and 1.29% by mass of the Earth's atmosphere, and air is the primary raw material used by industry to produce purified argon products. Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. The Martian atmosphere in contrast contains 1.6% of argon-40 and 5 ppm of argon-36. The Mariner spaceprobe fly-by of the planet Mercury in 1973 found that Mercury has a very thin atmosphere with 70% argon, believed to result from releases of the gas as a decay product from radioactive materials on the planet. In 2005, the Huygens probe also discovered the presence of argon-40 on Titan, the largest moon of Saturn. Isotopes The main isotopes of argon found on Earth are 40Ar (99.6%), 36Ar (0.34%), and 38Ar (0.06%). Naturally occurring 40K with a half-life of 1.25 years, decays to stable 40Ar (11.2%) by electron capture and positron emission, and also to stable 40Ca (88.8%) via beta decay. These properties and ratios are used to determine the age of rocks. In the Earth's atmosphere, 39Ar is made by cosmic ray activity, primarily with 40Ar. In the subsurface environment, it is also produced through neutron capture by 39K or alpha emission by calcium. 37Ar is created from the decay of 40Ca as a result of subsurface nuclear explosions. It has a half-life of 35 days. Compounds Argon’s complete octet of electrons indicates full s and p subshells. This full outer energy level makes argon very stable and extremely resistant to bonding with other elements. Before 1962, argon and the other noble gases were considered to be chemically inert and unable to form compounds; however, compounds of the heavier noble gases have since been synthesized. In August 2000, the first argon compounds were formed by researchers at the University of Helsinki. By shining ultraviolet light onto frozen argon containing a small amount of hydrogen fluoride, argon fluorohydride (HArF) was formed. It is stable up to 40 kelvins (−233 °C). Production Industrial Argon is produced industrially by the fractional distillation of liquid air, a process that separates liquid nitrogen, which boils at 77.3 K, from argon, which boils at 87.3 K and oxygen, which boils at 90.2 K. About 700,000 tons of argon are produced worldwide every year. In radioactive decays Argon-40, the most abundant isotope of argon, is produced by the decay of potassium-40 with a half-life of 1.26 years by electron capture or positron emission. Because of this, it is used in potassium-argon dating to determine the age of rocks. Applications Cylinders containing argon gas for use in extinguishing fire without damaging server equipment There are several different reasons why argon is used in particular applications: An inert gas is needed. In particular, argon is the cheapest alternative when diatomic nitrogen is not sufficiently inert. Low thermal conductivity is required. The electronic properties (ionization and/or the emission spectrum) are necessary. Other noble gases would probably work as well in most of these applications, but argon is by far the cheapest. Argon is inexpensive since it is a byproduct of the production of liquid oxygen and liquid nitrogen, both of which are used on a large industrial scale. The other noble gases (except helium) are produced this way as well, but argon is the most plentiful since it has the highest concentration in the atmosphere. The bulk of argon applications arise simply because it is inert and relatively cheap. Industrial processes Argon is used in some high-temperature industrial processes, where ordinarily unreactive substances become reactive. For example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. For some of these processes, the presence of nitrogen or oxygen gases might cause defects within the material. Argon is used in various types of metal inert gas welding such as tungsten inert gas welding, as well as in the processing of titanium and other reactive elements. An argon atmosphere is also used for growing crystals of silicon and germanium. Argon is an asphyxiant in the poultry industry, either for mass culling following disease outbreaks, or as a means of slaughter more humane than the electric bath. Argon's relatively high density causes it to remain close to the ground during gassing. Its non-reactive nature makes it suitable in a food product, and since it replaces oxygen within the dead bird, argon also enhances shelf life. Argon is sometimes used for extinguishing fires where damage to equipment is to be avoided (see photo). Preservative Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents. Aerial oxidation, hydrolysis, and other chemical reactions which degrade the products are retarded or prevented entirely. Bottles of high-purity chemicals and certain pharmaceutical products are available in sealed bottles or ampules packed in argon. In winemaking, argon is used to top-off barrels to avoid the aerial oxidation of ethanol to acetic acid during the aging process. Argon is also available in aerosol-type cans, which may be used to preserve compounds such as varnish, polyurethane, paint, etc. for storage after opening. US Patent 6629402 Since 2001 the American National Archives stores important national documents such as the Declaration of Independence and the Constitution within argon-filled cases to retard their degradation. Using argon reduces gas leakage, compared with the helium used in the preceding five decades. http://www.archives.gov/press/press-kits/charters.html#pressrelaese1 Accessed Feb 9, 2009 Laboratory equipment Gloveboxes are typically filled with argon, which recirculate over scrubbers to maintain an oxygen- and moisture-free atmosphere Argon may be used as the inert gas within Schlenk lines and gloveboxes. The use of argon over comparatively less expensive dinitrogen is preferred where nitrogen may react. Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in ICP spectroscopy. Argon is preferred for the sputter coating of specimens for scanning electron microscopy. Argon ions are also used for sputtering in microelectronics. Medical use Cryosurgery procedures such as cryoablation use liquefied argon to destroy cancer cells. In surgery it is used in a procedure called "argon enhanced coagulation" which is a form of argon plasma beam electrosurgery. The procedure carries a risk of producing gas embolism in the patient and has resulted in the death of one person via this type of accident. Blue argon lasers are used in surgery to weld arteries, destroy tumors, and to correct eye defects. It has also used experimentally to replace nitrogen in the breathing or decompression mix, to speed the elimination of dissolved nitrogen from the blood. See Argox (scuba). Lighting |An argon & mercury vapour discharge tube. Incandescent lights are filled with argon, to preserve the filaments at high temperature. It is used for the specific way it ionizes and emits light, such as in in plasma globes and calorimetry in experimental particle physics. Gas-discharge lamps filled with argon provide blue light. Argon is also used for the creation of blue laser light. Miscellaneous uses It is used for thermal insulation in energy efficient windows. Argon is also used in technical scuba diving to inflate a dry suit, because it is inert and has low thermal conductivity. Compressed argon is allowed to expand, to cool the seeker heads of the AIM-9 Sidewinder missile, and other missiles that use cooled thermal seeker heads. The gas is stored at high pressure. Argon-39, with a half life of 269 years, has been used for a number of applications, primarily ice core and ground water dating. Also, potassium-argon dating is used in dating igneous rocks. Safety Although argon is non-toxic, it does not satisfy the body's need for oxygen and is thus an asphyxiant. Argon is 25% more dense than air and is considered highly dangerous in closed areas. It is also difficult to detect because it is colorless, odorless, and tasteless. In confined spaces, it is known to result in death due to asphyxiation. A 1994 incident in Alaska that resulted in one fatality highlights the dangers of argon tank leakage in confined spaces, and emphasizes the need for proper use, storage and handling.

7,721 | Macroevolution | Macroevolution is a scale of analysis of evolution in separated gene pools. Matzke, Nicholas J. and Paul R. Gross. 2006. Analyzing Critical Analysis: The Fallback Antievolutionist Strategy. In Eugenie Scott and Glenn Branch, Not in Our Classrooms: Why Intelligent Design is Wrong for Our Schools, Beacon Press, Boston ISNB:0807032786 Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, , p12 which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population. The process of speciation may fall within the purview of either, depending on the forces thought to drive it. Paleontology, evolutionary developmental biology, comparative genomics and genomic phylostratigraphy contribute most of the evidence for the patterns and processes that can be classified as macroevolution. An example of macroevolution is the appearance of feathers during the evolution of birds from theropod dinosaurs. Origin of the term Russian entomologist Yuri Filipchenko (or Philipchenko, depending on the transliteration) first coined the terms "macroevolution" and "microevolution" in 1927 in his German language work, "Variabilität und Variation". Since the inception of the two terms, their meanings have been revised several times and even fallen into disfavor amongst scientists who prefer to speak of biological evolution as one process. Macroevolution: Its definition, Philosophy and History Macroevolution and the modern evolutionary synthesis Within the Modern Synthesis school of thought, macroevolution is thought of as the compounded effects of microevolution. Thus, the distinction between micro- and macroevolution is not a fundamental one the only difference between them is of time and scale. However, it should be noted that time is not a necessary distinguishing factor macroevolution can happen without gradual compounding of small changes; whole-genome duplication can result in macroevolution occurring over a single generation - especially in plants. One of the most significant applications of this is found in the evolution of the vertebrates, which was mediated by duplications of the hox gene complex. Research topics Some examples of subjects whose study falls within the realm of macroevolution: Adaptive radiations such as The Cambrian Explosion. Changes in biodiversity through time. Genomic evolution, like horizontal gene transfer, genome fusions in endosymbioses, and adaptive changes in genome size. Mass extinctions. Speciation and extinction rates. The debate between punctuated equilibrium and gradualism. The role of development in shaping evolution, particularly such topics as heterochrony and phenotypic plasticity. Criticisms of macroevolution The term "macroevolution" frequently arises within the context of the evolution/creation debate, usually brandished by creationists alleging a significant difference between the evolutionary changes observed in field and laboratory studies and the larger scale macroevolutionary changes that scientists believe to have taken thousands or millions of years to occur. They may accept that evolutionary change is possible within species ("microevolution"), but deny that one species can evolve into another ("macroevolution"). These arguments are rejected by mainstream science, which holds that there is ample evidence that macroevolution has occurred in the past. CB901: No Macroevolution The consensus of the scientific community is that the alleged micro-macro division is an artificial construct made by creationists and does not accurately reflect the actual processes of evolution. Evolutionary theory (including macroevolutionary change) remains the dominant scientific paradigm for explaining the origins of Earth's biodiversity. Its occurrence, while controversial with the public at large, is not disputed within the scientific community. While details of macroevolution are continuously studied by the scientific community, the overall theory behind macroevolution (i.e. common descent) has been overwhelmingly consistent with empirical data. Predictions of empirical data from the theory of common descent have been so consistent that biologists often refer to it as the "fact of evolution". 29+ Evidences for Macroevolution: The Scientific Case for Common Descent, Douglas L. Theobald, TalkOrigins Archive, Vers. 2.83, 2004, 12 Jan, 2004. Nicholas Matzke and Paul R. Gross have accused creationists of using "strategically elastic" definitions of micro- and macroevolution when discussing the topic. The actual definition of macroevolution accepted by scientists is "any change at the species level or above" (phyla, group, etc.) and microevolution is "any change below the level of species." Matzke and Gross state that many creationist critics define macroevolution as something that cannot be attained, as these critics describe any observed evolutionary change as "just microevolution".

7,722 | Multiplicative_function | Outside number theory, the term multiplicative function is usually used for completely multiplicative functions. This article discusses number theoretic multiplicative functions. In number theory, a multiplicative function is an arithmetic function f(n) of the positive integer n with the property that f(1) = 1 and whenever a and b are coprime, then f(ab) = f(a) f(b). An arithmetic function f(n) is said to be completely multiplicative (or totally multiplicative) if f(1) = 1 and f(ab) = f(a) f(b) holds for all positive integers a and b, even when they are not coprime. Examples Examples of multiplicative functions include many functions of importance in number theory, such as: (n): Euler's totient function , counting the positive integers coprime to (but not bigger than) n (n): the Möbius function, related to the number of prime factors of square-free numbers gcd(n,k): the greatest common divisor of n and k, where k is a fixed integer. d(n): the number of positive divisors of n, (n): the sum of all the positive divisors of n, k(n): the divisor function, which is the sum of the k-th powers of all the positive divisors of n (where k may be any complex number). In special cases we have 0(n) = d(n) and 1(n) = (n), : the number of non-isomorphic abelian groups of order n. 1(n): the constant function, defined by 1(n) = 1 (completely multiplicative) the indicator function of the set of squares (or cubes, or fourth powers, etc.) Id(n): identity function, defined by Id(n) = n (completely multiplicative) Idk(n): the power functions, defined by Idk(n) = nk for any natural (or even complex) number k (completely multiplicative). As special cases we have Id0(n) = 1(n) and Id1(n) = Id(n), (n): the function defined by (n) = 1 if n = 1 and = 0 if n > 1, sometimes called multiplication unit for Dirichlet convolution or simply the unit function; sometimes written as u(n), not to be confused with (n) (completely multiplicative). (n/p), the Legendre symbol, where p is a fixed prime number (completely multiplicative). (n): the Liouville function, related to the number of prime factors dividing n (completely multiplicative). (n), defined by (n)=(-1)(n), where the additive function (n) is the number of distinct primes dividing n. All Dirichlet characters are completely multiplicative functions. An example of a non-multiplicative function is the arithmetic function r2(n) - the number of representations of n as a sum of squares of two integers, positive, negative, or zero, where in counting the number of ways, reversal of order is allowed. For example: 1 = 12 + 02 = (-1)2 + 02 = 02 + 12 = 02 + (-1)2 and therefore r2(1) = 4 ≠ 1. This shows that the function is not multiplicative. However, r2(n)/4 is multiplicative. In the On-Line Encyclopedia of Integer Sequences, sequences of values of a multiplicative function have the keyword "mult". See arithmetic function for some other examples of non-multiplicative functions. Properties A multiplicative function is completely determined by its values at the powers of prime numbers, a consequence of the fundamental theorem of arithmetic. Thus, if n is a product of powers of distinct primes, say n = pa qb ..., then f(n) = f(pa) f(qb) ... This property of multiplicative functions significantly reduces the need for computation, as in the following examples for n = 144 = 24 · 32: d(144) = 0(144) = 0(24)0(32) = (10 + 20 + 40 + 80 + 160)(10 + 30 + 90) = 5 · 3 = 15, (144) = 1(144) = 1(24)1(32) = (11 + 21 + 41 + 81 + 161)(11 + 31 + 91) = 31 · 13 = 403, *(144) = *(24)*(32) = (11 + 161)(11 + 91) = 17 · 10 = 170. Similarly, we have: (144)=(24)(32) = 8 · 6 = 48 In general, if f(n) is a multiplicative function and a, b are any two positive integers, then f(a) · f(b) = f(gcd(a,b)) · f(lcm(a,b)). Every completely multiplicative function is a homomorphism of monoids and is completely determined by its restriction to the prime numbers. Convolution If f and g are two multiplicative functions, one defines a new multiplicative function f * g, the Dirichlet convolution of f and g, by where the sum extends over all positive divisors d of n. With this operation, the set of all multiplicative functions turns into an abelian group; the identity element is . Relations among the multiplicative functions discussed above include: * 1 = (the Möbius inversion formula) ( Idk) * Idk = (generalized Möbius inversion) * 1 = Id d = 1 * 1 = Id * 1 = * d k = Idk * 1 Id = * 1 = * Idk = k * The Dirichlet convolution can be defined for general arithmetic functions, and yields a ring structure, the Dirichlet ring. The Dirichlet convolution of two multiplicative functions is multiplicative This follows by direct evaluation of making repeated use of the fact that and if and as in Now using the fact that and are multiplicative this becomes Proving convolution identities There is a very useful theorem for proving convolution identities, which says that if f, g and h are multiplicative, and one wants to prove that then it suffices to prove it for powers of primes. The proof of this follows easily from the fact that both sides of the above equation are multiplicative. The corresponding Dirichlet series obey the relation This means that convolution identities may be used to find closed forms of Dirichlet series corresponding to multiplicative functions. These closed forms may in turn be used to study the average order of multiplicative functions through the use of Perron's formula. We may now prove some convolution identities of multiplicative functions by verifying that they hold for powers of primes. First example: Moebius inversion We have This certainly holds for powers of primes, where the left evaluates to This proves the Moebius inversion formula, through In terms of Dirichlet series, The Riemann Zeta function will appear in all convolutions presented here. Second example: the classic totient identity We show that The left is In terms of Dirichlet series, Third example: the square of the divisor function We show that: where is the indicator function of the set of naturals that are squares. The right is: The left is: Now there are two cases, depending on whether v is even or odd. Let where . This gives: Next let where . This in turn gives: In terms of Dirichlet series: Fourth example: an exotic identity Here we show that The left is Once more there are two cases. Let where .

7,723 | Amos_Bronson_Alcott | Amos Bronson Alcott (November 29, 1799 – March 4, 1888) was an American teacher and writer. He is remembered for founding a short-lived and unconventional school as well as an utopian community known as "Fruitlands", and for his association with Transcendentalism. He was the father of the novelist Louisa May Alcott. Life and work Early life Alcott was born on Spindle Hill in the town of Wolcott, New Haven County, Connecticut "Old New Haven", Juliet Lapidos, The Advocate, March 17, 2005 on November 29, 1799. His father, Joseph Chatfield Alcox, was a farmer and mechanic whose ancestors, then bearing the name of Alcocke, had settled in eastern Massachusetts in colonial days. The son adopted the spelling "Alcott" in his early youth. Alcott taught himself to read and was self-educated. Hankins, Barry. The Second Great Awakening and the Transcendentalists. Westport, Connecticut: Greenwood Press, 2004: 129. ISBN 0-313-31848-4 He began in 1814 to earn his living by working in a clock factory in Plymouth, Connecticut. He left home at the age of 17 and for many years after 1815 he was a door-to-door salesman in the American South, selling peddled books and merchandise. He began teaching in Bristol, Connecticut in 1823, and subsequently conducted schools in Cheshire, Connecticut, in 1825-1827, again in Bristol in 1827-1828, in Boston, Massachusetts in 1828-1830, in Germantown (now part of Philadelphia, Pennsylvania) in 1831-1833, and in Philadelphia in 1833. As a young teacher he was most convinced by the educational philosophy of the Swiss pedagogue Johann Heinrich Pestalozzi. In the spring of 1830 he married Abigail May, McFarland, Philip. Hawthorne in Concord. New York: Grove Press, 2004. p. 79. ISBN 0802117767 the sister of Samuel J. May, the reformer and abolitionist. Alcott himself was a Garrisonian abolitionist, and pioneered the strategy of tax resistance to slavery which Henry David Thoreau made famous in Civil Disobedience. Gross, David (ed.) We Won’t Pay!: A Tax Resistance Reader ISBN 1434898253 pp. 178-179 Alcott publicly debated with Thoreau the use of force and passive resistance to slavery; along with Thoreau he was among the financial and moral supporters of John Brown and occasionally helped fugitive slaves escape on the Underground Railroad. Educator In 1834 he opened the "Temple School" in Boston, so called because it was located in a Masonic Temple building. The school was briefly famous, and then infamous, because of his original methods. Alcott's plan was to develop self-instruction on the basis of self-analysis, with an emphasis on conversation and questioning rather than lecturing and drill, which were prevalent in the U.S. classrooms of the time. Alongside writing and reading, he gave lessons in "spiritual culture", which often involved the Gospels. Reformers like Bronson Alcott advocated for object teaching in writing instruction. Before 1830, writing (except in higher education) equated to rote drills in the rules of grammar, spelling, vocabulary, penmanship, and transcription of adult texts. However, in the 1830s, progressive reformers like Bronson Alcott, influenced by Fröbel, Herbart, and Pestalozzi, began to advocate writing about subjects from students’ personal experiences. Reformers debated against beginning instruction with rules, and were in favor of helping students learn to write by writing. Alcott sometimes refused corporal punishment as a means of disciplining his students; instead, he offered his own hand for an offending student to strike, saying that any failing was the teacher's responsibility. The shame and guilt this method induced, he believed, was far superior to the fear instilled by corporal punishment; when he used physical "correction" he required that the students be unanimously in support of its application, even including the student to be punished. As assistants in the Temple School, Alcott had two of nineteenth-century America's most talented women writers, Elizabeth Palmer Peabody (who published A Record of Mr. Alcott's School in 1835) and more briefly Margaret Fuller; as students he had the children of the Boston intellectual classes, including Josiah Quincy, grandson of the president of Harvard University. Alcott's methods were not well received; many readers found his conversations on the Gospels close to blasphemous, a few brief but frank discussions of birth and circumcision with the children were considered obscene, and many of the public found his ideas ridiculous. For instance, the influential conservative Unitarian Andrews Norton derided the book as one-third blasphemy, one-third obscenity, and the rest nonsense. The school was widely denounced in the press, with only a few scattered supporters, and Alcott was rejected by most public opinion. After the school closed, Alcott was increasingly financially desperate as the controversy caused many parents to remove their students. In a later "parlor school," Alcott alienated many parents by admitting an African American child to the class, whom he then refused to expel in the face of protests. Alcott's pedagogy was a forerunner of progressive and democratic schooling. Transcendentalism and Fruitlands Orchard House in Concord, Massachusetts. Beginning in 1836, Alcott was a frequent member of the Transcendental Club alongside people like Ralph Waldo Emerson, Orestes Brownson and Theodore Parker. Buell, Lawrence. Emerson. Cambridge, Massachusetts: The Belknap Press of Harvard University Press, 2003: 32–33. ISBN 0-674-01139-2 A biographer of Emerson described the group as "the occasional meetings of a changing body of liberal thinkers, agreeing in nothing but their liberality". Gura, Philip F. American Transcendentalism: A History. New York: Hill and Wang, 2007: 5. ISBN 0-8090-3477-8 Frederick Henry Hedge wrote of the group's nature: "There was no club in the strict sense... only occasional meetings of like-minded men and women". In 1840 Alcott removed to Concord, Massachusetts. In the early 1840s, he contributed a series of "Orphic Sayings" to The Dial, the journal of the Transcendentalists, which were widely mocked for being dense and meaningless. In the first issue, for example, he wrote: Alcott left Concord for a visit to England on May 8, 1842, where he met two admirers, Charles Lane and Henry C. Wright. Packer, Barbara L. The Transcendentalists. Athens, Georgia: The University of Georgia Press, 2007: 147–148. ISBN 9780820329581 The group formed "Fruitlands", in the town of Harvard, Massachusetts, a utopian socialist experiment in farm living and nature meditation as tending to develop the best powers of body and soul. The experiment quickly collapsed, and Alcott moved his family to Still River, a village within Harvard, in January 1844. In November, the family returned their Concord home "Hillside" Ehrlich, Eugene and Gorton Carruth. The Oxford Illustrated Literary Guide to the United States. New York: Oxford University Press, 1982: 62. ISBN 0195031865 (later renamed "The Wayside" by Nathaniel Hawthorne) near that of Ralph Waldo Emerson. Alcott removed to Boston four years later, and again back to Concord after 1857, where he and his family lived in the Orchard House until 1877. While there, Alcott served as Superintendent to the Concord Public Schools in 1860-1861. He spoke, as opportunity offered, before the "lyceums" then common in various parts of the United States, or addressed groups of hearers as they invited him. These "conversations" as he called them, were more or less informal talks on a great range of topics, spiritual, aesthetic and practical, in which he emphasized the ideas of the school of American Transcendentalists led by Emerson, who was always his supporter and discreet admirer. He often discussed Platonic philosophy, the illumination of the mind and soul by direct communion with Spirit; upon the spiritual and poetic monitions of external nature; and upon the benefit to man of a serene mood and a simple way of life. His teachings greatly influenced the growing New Thought movement of the mid 1800s. Later life In his last years, his daughter, the writer Louisa May Alcott, provided for him. He was the founder of the "Concord School of Philosophy and Literature", which had its first session in 1879 in Alcott's study in the Orchard House. In 1880 the school moved to the building next to the house, called the Hillside Chapel, where he held conversations and invited others to give lectures during a part of several successive summers on many themes in philosophy, religion and letters. This school is considered to be one of the first formal adult education centers in America, and was attended by scholars from several countries. The school ran for nine years, closing after its last session in 1888 after Alcott died. The school was reopened in the 1970s, and still runs today with a Summer Conversational Series in its original building at Orchard House, now run by the Louisa May Alcott Memorial Association. Alcott's published books, all from late in his life, included New Connecticut, Tablets (1868), Concord Days (1872), and Sonnets and Canzonets (1882). He left a large collection of journals and memorabilia, most of which remain unpublished. He died in Boston on March 4, 1888. Just two days later, his daughter, Louisa May Alcott, died of aftereffects of mercury poisoning. Criticism and legacy Alcott's philosophical teachings have been criticized as inconsistent, hazy or abrupt. He formulated no system of philosophy, and shows the influence of Plato, German mysticism, and Kant as filtered through Coleridge. Like Emerson, Alcott was always optimistic, idealistic, and individualistic in thinking. The teachings of Dr. William Ellery Channing a few years before had laid the groundwork for the work of most of the Concord Transcendentalists, also. Of the contributors to The Dial, Alcott was by far the most widely mocked in the press, chiefly for the high-flown rhetoric of his "Orphic Sayings". Alcott has also been widely criticized for his inability to support his family above poverty level. Margaret Fuller referred to Alcott as "a philosopher of the balmy times of ancient Greece—a man whom the worldings of Boston hold in as much horror as the worldings of Athens held Socrates." Nelson, Randy F. (editor). The Almanac of American Letters. Los Altos, California: William Kaufmann, Inc., 1981: 152. ISBN 086576008X From the other perspective, Alcott's unique teaching ideas created an environment which produced two famous daughters in different fields, in a time when women were not commonly encouraged to have independent careers. His ideas also helped to found one of the first adult education centers in America, and provide the foundation for future generations of liberal education. Many of Alcott's educational principles are still used in classrooms today, including "teach by encouragement," art education, music education, acting exercises, learning through experience, risk-taking in the classroom, tolerance in schools, physical education/recess, and early childhood education. While many of Alcott's ideas are still on the liberal/radical edge today, they are still common themes in society, including vegetarian/veganism, sustainable living, and temperance/self control. Alcott described his diet as a "Pythagorean diet": excluding meat, eggs, butter, cheese, and milk and drinking only well water. Baker, Carlos. Emerson Among the Eccentrics: A Group Portrait.

Gray, Henry and Lewis, Warren. Anatomy of the Human Body, page 57 (Lea and Febiger 1918). Via Google Books. Retrieved (2009-02-03). A fetus (also spelled foetus or fœtus) is a developing mammal or other viviparous vertebrate, after the embryonic stage and before birth. The plural is fetuses. In humans, the fetal stage of prenatal development begins about eight weeks after fertilization, when the major structures and organ systems have formed, MedicineNet.com. See also Dictionary.com. and lasts until birth. Some authorities suggest that the embryonic stage may last only seven weeks. See Encyclopedia Britannica: "In humans, the organism is called an embryo for the first seven or eight weeks after conception, after which it is called a fetus." Also see The Columbia Encyclopedia (Sixth Edition). Retrieved 2007-03-05: "the fetal stage begins seven to eight weeks after fertilization of the egg, when the embryo assumes the basic shape of the newborn and all the organs are present." Etymology and spelling variations The word fetus is from the Latin fetus, meaning offspring, bringing forth, hatching of young. Harper, Douglas. (2001). Online Etymology Dictionary. Retrieved 2007-01-20. It has Indo-European roots related to sucking or suckling. The American Heritage Dictionary of the English Language, Fourth Edition. Retrieved 2007-01-22. Fœtus is an English spelling that has been in use since at least 1594, according to the Oxford English Dictionary, which describes "fœtus" as "incorrectly written"; it arose as a hypercorrection based on an incorrect etymology, in other words insufficient knowledge of Latin. The variant fœtus may have originated with an error by Saint Isidore of Seville, in AD 620. The preferred spelling in most English-speaking countries (except in professional literature) is foetus or fœtus, although the original spelling based on the correct Latin etymology fetus persists in the United States. However, fetus is now also the standard spelling throughout the English-speaking world in medical journals and other technical usage. New Oxford Dictionary of English The only correct English plural is "fetuses". The pseudo-Latin plural "feti" is sometimes seen in English, but this is based on insufficient knowledge of Latin. (In Latin, fētus is fourth declension, and its plural is fētūs.) Development Selection from "Views of a Fetus in the Womb", a drawing by Leonardo da Vinci.The fetal stage begins about eight weeks after fertilization. The fetus is not as sensitive to damage from environmental exposures as the embryo was, though toxic exposures can often cause physiological abnormalities or minor congenital malformation. Drews, Ulrich. Color Atlas of Embryology, page 360 (Thieme 1995). Fetal growth can be terminated by various factors, including miscarriage, feticide committed by a third party, or induced abortion. Throughout the fetal stage, the fetus continues to be connected to the placenta by the umbilical cord, which supplies the fetus with oxygenated, nutrient-rich blood from the placenta, and conversely returns the deoxygenated, nutrient-depleted blood to the placenta. The fetus is surrounded by amniotic fluid, which (among other things) cushions against blows to the mother's abdomen, allows for easier fetal movement, promotes muscular/skeletal development, and helps protect the fetus from heat loss. The following timeline describes some of the specific changes in fetal anatomy and physiology by fertilization age (i.e. the time elapsed since fertilization). Obstetricians often find it convenient to instead measure gestational age from two weeks earlier than fertilization, but the term “gestational age” is often ambiguous, and there is no uniform method for counting it. ’’'Dorland's Medical Dictionary.’’ Also see "Mini-Review: Prenatal ages and stages - measures and errors," Teratology, Volume 61 Issue 5, Pages 382-384 (2000). Also see Rahman, Anika et al. “A Global Review of Laws on Induced Abortion”, 1985-1997, International Family Planning Perspectives, volume 24 (1998). Embryologists typically measure age from fertilization. Segen, J.C. The Dictionary of Modern Medicine, page 187: "obstetricians calculate gestational age; embryologists are more correct as they calculate the ovulation or fertilization age." Also see Dudek, Ronald et al. Embryology. Also see Drews, Ulrich. Color Atlas of Embryology. For purposes of this article, age is measured from fertilization, except as noted. 8 weeks: condition at start of fetal stage Artist's depiction of fetus 8 weeks after fertilization (i.e. 10 weeks LMP).

Mayo Clinic. “9.1 Developmental stages” (online course in embryology for medicine students developed by the universities of Fribourg, Lausanne and Bern with the support of the Swiss Virtual Campus). The first movements occur around this time, and those movements include sideward bendings of the head. Prechtl, Heinz. "Prenatal and Early Postnatal Development of Human Motor Behavior" in Handbook of brain and behaviour in human development, Kalverboer and Gramsbergen eds., pp. 415-418 (2001 Kluwer Academic Publishers): "The first movements to occur are sideward bendings of the head....At 9-10 weeks postmestrual age complex and generalized movements occur. These are the so-called general movements (Prechtl et al., 1979) and the startles. Both include the whole body, but the general movements are slower and have a complex sequence of involved body parts, while the startle is a quick, phasic movement of all limbs and trunk and neck." Generally speaking, fetal movement can be classified as either elicited (e.g. reflexive) or spontaneous, and spontaneous movements may be triggered by either the spine or the brain. Whether a spontaneous movement is supraspinally determined (i.e. caused by signals from the brain) can be inferred by comparison to movements of an anencephalic fetus, which has no brain. De Vries, Johanna et al. “Fetal Motility in the First Half of Pregnancy”, in Continuity of Neural Functions from Prenatal to Postnatal Life, pages 4 and 63 (1984 Cambridge University Press, edited by Heinz F.

Artist's depiction of fetus at 18 weeks after fertilization, about 6.5 inches (16.5 cm) crown to rump. At nine weeks the fetus is able to bend fingers around an object; in response to a touch on the foot, the fetus bends the legs or curls the toes to move away from an object. During weeks 9-12, the face is “well-formed” and the fetus is three to six inches (152 mm) in length. From weeks 9 to 12, the head makes up nearly half of the fetus' size, the fetal eyelids close and remain closed for several months, and the appearance of the genitals in males and females becomes more apparent.

Jones, Sandy et al. Great Expectations, page 69 (Sterling Publishing 2004). Tooth buds appear, the limbs are long and thin, and red blood cells are produced in the liver, however the majority of red blood cells will be made later in gestation (at 21 weeks) by bone marrow. A fine hair called lanugo develops on the head. The gastrointestinal tract, still forming, starts to collect sloughed skin and lanugo, as well as hepatic products, forming meconium (stool). Fetal skin is almost transparent. More muscle tissue and bones have developed, and the bones become harder. The first measurable signs of EEG movement occur in the 12th week. Vogel, Friedrich. Genetics and the Electroencephalogram (Springer 2000): "Slow EEG activity (0.5 – 2 c/s) can be demonstrated in the fetus even at the conceptual age of three months." Retrieved 2007-03-05. By the end of this stage, the fetus has reached about 15 cm (6 inches). 16 to 25 weeks after fertilization The lanugo covers the entire body. Eyebrows, eyelashes, fingernails, and toenails appear. The fetus has increased muscle development. Alveoli (air sacs) are forming in lungs. The nervous system develops enough to control some body functions. The cochlea are now developed, though the myelin sheaths in the neural portion of the auditory system will continue to develop until 18 months after birth. The respiratory system has developed to the point where gas exchange is possible. The quickening, which refers to the first maternally discernible fetal movements, are often felt during this period, although the fetus has been moving throughout the fetal stage. A woman pregnant for the first time (i.e. a primiparous woman) typically feels fetal movements at about 18–19 weeks, whereas a woman who has already given birth at least two times (i.e. a multiparous woman) will typically feel movements around 16 weeks.

Lungs are not fully mature. Thalamic brain connections, which mediate sensory input, form. Bones are fully developed, but are still soft and pliable. Iron, calcium, and phosphorus become more abundant. Fingernails reach the end of the fingertips. The lanugo begins to disappear, until it is gone except on the upper arms and shoulders.

"full-term" defined by Memidex/WordNet. It may be 48 to 53 cm (19 to 21 inches) in length, when born. Control of movement is limited at birth, and purposeful voluntary movements develop all the way until puberty. Stanley, Fiona et al.

The voluntary control of movement develops and matures during a prolonged period up to puberty...." Becher, Julie-Claire. "Insights into Early Fetal Development", Behind the Medical Headlines (Royal College of Physicians of Edinburgh and Royal College of Physicians and Surgeons of Glasgow October 2004) Variation in growth There is much variation in the growth of the fetus. When fetal size is less than expected, that condition is known as intrauterine growth restriction (IUGR) also called fetal growth restriction (FGR); factors affecting fetal growth can be maternal, placental, or fetal. Holden, Chris and MacDonald, Anita. Nutrition and Child Health (Elsevier 2000). Retrieved 2007-03-04. Maternal factors include maternal weight, body mass index, nutritional state, emotional stress, toxin exposure (including tobacco, alcohol, heroin, and other drugs which can also harm the fetus in other ways), and uterine blood flow. Placental factors include size, microstructure (densities and architecture), umbilical blood flow, transporters and binding proteins, nutrient utilization and nutrient production. Fetal factors include the fetus genome, nutrient production, and hormone output. Also, female fetuses tend to weigh less than males, at full term. Fetal growth is often classified as follows: small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational age (LGA). Queenan, John. Management of High-Risk Pregnancy (Blackwell 1999). Retrieved 2007-03-04. SGA can result in low birth weight, although premature birth can also result in low birth weight. Low birth weight increases risk for perinatal mortality (death shortly after birth), asphyxia, hypothermia, polycythemia, hypocalcemia, immune dysfunction, neurologic abnormalities, and other long-term health problems. SGA may be associated with growth delay, or it may instead be associated with absolute stunting of growth. Viability The lower limit of viability is approximately five months gestational age, and usually later. Halamek, Louis. "Prenatal Consultation at the Limits of Viability", NeoReviews, Vol.4 No.6 (2003): "most neonatologists would agree that survival of infants younger than approximately 22 to 23 weeks’ estimated gestational age [i.e. 20 to 21 weeks' estimated fertilization age] is universally dismal and that resuscitative efforts should not be undertaken when a neonate is born at this point in pregnancy." According to The Developing Human: Human fetus, age unknown Viability is defined as the ability of fetuses to survive in the extrauterine environment... There is no sharp limit of development, age, or weight at which a fetus automatically becomes viable or beyond which survival is assured, but experience has shown that it is rare for a baby to survive whose weight is less than 500 gm or whose fertilization age is less than 22 weeks. Even fetuses born between 26 and 28 weeks have difficulty surviving, mainly because the respiratory system and the central nervous system are not completely differentiated... If given expert postnatal care, some fetuses weighing less than 500 gm may survive; they are referred to as extremely low birth weight or immature infants.... Prematurity is one of the most common causes of morbidity and perinatal death. Moore, Keith and Persaud, T. The Developing Human: Clinically Oriented Embryology, page 103 (Saunders 2003). During the past several decades, neonatal care has improved with advances in medical science, and therefore the limit of viability has moved earlier. Roe v. Wade, 410 U.S. 113 (1973) ("viability is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks.") Retrieved 2007-03-04. As of 2006, the two youngest children to survive premature birth are thought to be James Elgin Gill (born on 20 May 1987 in Ottawa, Canada, at 21 weeks and 5 days gestational age), and Amillia Taylor (born on 24 October 2006 in Miami, Florida, at 21 weeks and 6 days gestational age). Baptist Hospital of Miami, Fact Sheet (2006). Both children were born just under 20 weeks from fertilization, or a few days past the midpoint of an average full-term pregnancy. Despite their premature births, both developed into healthy children. Fetal pain The subject of fetal pain and suffering is controversial. There may be an "emerging consensus among developmental neurobiologists that the establishment of thalamocortical connections" (at about 26 weeks) is a critical event with regard to fetal perception of pain. Nevertheless, because pain can involve sensory, emotional and cognitive factors, it is "impossible to know" when painful experiences may become possible, even if it is known when thalamocortical connections are established. Johnson, Martin and Everitt, Barry. Essential reproduction (Blackwell 2000): "The multidimensionality of pain perception, involving sensory, emotional, and cognitive factors may in itself be the basis of conscious, painful experience, but it will remain difficult to attribute this to a fetus at any particular developmental age." Retrieved 2007-02-21. Some experts have asserted that a fetus can sense pain as early as 13 ½ weeks. Collins, Vincent et al."Fetal Pain and Abortion: the Medical Evidence", Studies in Law and Medicine, No 18 (1984): "because the requisite neurological structures are present at that time and because they are functioning, as evidenced by the aversive response of the human fetus, it may be concluded with reasonable medical certainty that the fetus can sense pain at least by 13 ½ weeks." In summary, there is good evidence that from about 26 weeks gestation the fetal brain can be considered a functional unit capable of processing noxious sensory input, and pain before that point may also be possible. Also see "Study: Fetus feels no pain until third trimester" MSNBC (reporting on the study by Lee and Ralston). Two authors of the 2005 study published in JAMA did not report their abortion-related activities, which pro-life groups called a conflict of interest; the editor of JAMA responded that JAMA probably would have mentioned those activities if they had been disclosed, but still would have published the study. See Denise Grady, “Study Authors Didn't Report Abortion Ties”, New York Times (2005-08-26). The study published in JAMA has also been criticized on scientific grounds. See Anand, K. "A Scientific Appraisal of Fetal Pain and Conscious Sensory Perception", written testimony to Congress (2005). Retrieved 2007-03-10. The science of fetal pain is not completely certain, and the nature of pain remains elusive. See “Science, politics and fetal pain; Abortion issue muddies real debate on fetal pain perception”, About Kids Health, The Hospital for Sick Children (2006-05-18), via Archive.org: "Although there is a political and moral component to this particular debate, questions about the nature of pain, pain perception and the mechanism of pain have been ongoing for years. For example, it was once widely believed that infants do not experience pain, a belief now shown to be incorrect. At the same time, allodynia, a condition in which even a gentle touch becomes painful, and congenital insensitivity to pain, or an inability to feel pain under any circumstance including injury, illustrate the bizarre and still-elusive nature of pain." Whether a fetus has the ability to feel pain and to suffer is part of the abortion debate. White, R. Frank.

For example, in the United States, legislation has been proposed by pro-life advocates requiring abortion providers to tell a woman that the fetus may feel pain during the abortion procedure, and that require her to accept or decline anesthesia for the fetus.

The circulatory system of a human fetus works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the woman through the placenta and the umbilical cord. Whitaker, Kent. Comprehensive Perinatal and Pediatric Respiratory Care (Delmar 2001). Retrieved 2007-03-04. Blood from the placenta is carried to the fetus by the umbilical vein. About half of this enters the fetal ductus venosus and is carried to the inferior vena cava, while the other half enters the liver proper from the inferior border of the liver. The branch of the umbilical vein that supplies the right lobe of the liver first joins with the portal vein. The blood then moves to the right atrium of the heart. In the fetus, there is an opening between the right and left atrium (the foramen ovale), and most of the blood flows from the right into the left atrium, thus bypassing pulmonary circulation. The majority of blood flow is into the left ventricle from where it is pumped through the aorta into the body. Some of the blood moves from the aorta through the internal iliac arteries to the umbilical arteries, and re-enters the placenta, where carbon dioxide and other waste products from the fetus are taken up and enter the woman's circulation. Some of the blood from the right atrium does not enter the left atrium, but enters the right ventricle and is pumped into the pulmonary artery. In the fetus, there is a special connection between the pulmonary artery and the aorta, called the ductus arteriosus, which directs most of this blood away from the lungs (which aren't being used for respiration at this point as the fetus is suspended in amniotic fluid). Postnatal development With the first breath after birth, the system changes suddenly. The pulmonary resistance is dramatically reduced ("pulmo" is from the Latin for "lung"). More blood moves from the right atrium to the right ventricle and into the pulmonary arteries, and less flows through the foramen ovale to the left atrium. The blood from the lungs travels through the pulmonary veins to the left atrium, increasing the pressure there. The decreased right atrial pressure and the increased left atrial pressure pushes the septum primum against the septum secundum, closing the foramen ovale, which now becomes the fossa ovalis. This completes the separation of the circulatory system into two halves, the left and the right. The ductus arteriosus normally closes off within one or two days of birth, leaving behind the ligamentum arteriosum. The umbilical vein and the ductus venosus closes off within two to five days after birth, leaving behind the ligamentum teres and the ligamentum venosus of the liver respectively. Differences from the adult circulatory system Remnants of the fetal circulation can be found in adults: Dudek, Ronald and Fix, James. Board Review Series Embryology (Lippincott 2004). Retrieved 2007-03-04. University of Michigan Medical School, Fetal Circulation and Changes at Birth. Retrieved 2007-03-04. Fetal Adult foramen ovale fossa ovalisductus arteriosus ligamentum arteriosum extra-hepatic portion of the fetal left umbilical vein ligamentum teres hepatis (the "round ligament of the liver"). intra-hepatic portion of the fetal left umbilical vein (the ductus venosus) ligamentum venosum proximal portions of the fetal left and right umbilical arteries umbilical branches of the internal iliac arteries distal portions of the fetal left and right umbilical arteries medial umbilical ligaments (urachus) In addition to differences in circulation, the developing fetus also employs a different type of oxygen transport molecule than adults (adults use adult hemoglobin). Fetal hemoglobin enhances the fetus' ability to draw oxygen from the placenta. Its association curve to oxygen is shifted to the left, meaning that it will take up oxygen at a lower concentration than adult hemoglobin will. This enables fetal hemoglobin to absorb oxygen from adult hemoglobin in the placenta, which has a lower pressure of oxygen than at the lungs. Developmental problems Congenital anomalies are anomalies that are acquired before birth. Infants with certain congenital anomalies of the heart can survive only as long as the ductus remains open: in such cases the closure of the ductus can be delayed by the administration of prostaglandins to permit sufficient time for the surgical correction of the anomalies. Conversely, in cases of patent ductus arteriosus, where the ductus does not properly close, drugs that inhibit prostaglandin synthesis can be used to encourage its closure, so that surgery can be avoided. A developing fetus is highly susceptible to anomalies in its growth and metabolism, increasing the risk of birth defects. One area of concern is the pregnant woman's lifestyle choices made during pregnancy Dalby, JT. (1978).Environmental effects on prenatal development Journal of Pediatric Psychology, 3, 105-109. Diet is especially important in the early stages of development. Studies show that supplementation of the woman's diet with folic acid reduces the risk of spina bifida and other neural tube defects. Another dietary concern is whether the woman eats breakfast. Skipping breakfast could lead to extended periods of lower than normal nutrients in the woman's blood, leading to a higher risk of prematurity, or other birth defects in the fetus. During this time alcohol consumption may increase the risk of the development of Fetal alcohol syndrome, a condition leading to mental retardation in some infants. Smoking during pregnancy may also lead to reduced birth weight. Low birth weight is defined as 2500 grams (5.5 lb). Low birth weight is a concern for medical providers due to the tendency of these infants, described as premature by weight, to have a higher risk of secondary medical problems. Legal issues In the United States, some states have laws that impose strict punishments for those who inflict violence that results in damage to a fetus or the unwanted termination of a pregnancy. The severity of the punishment, and the stage of fetal development where laws start to apply vary from state to state. National Conference of State Legislatures. (June 2006). "Fetal Homicide". Retrieved January 19 2007. Abortion of a fetus is legal in many countries such as Australia, Canada, the United Kingdom, and the United States. Many of those countries that allow abortion during the fetal stage have gestational time limits, so that late-term abortions are not normally allowed. Anika Rahman, Laura Katzive and Stanley K. Henshaw. A Global Review of Laws on Induced Abortion, 1985-1997, International Family Planning Perspectives (Volume 24, Number 2, June 1998).

7,725 | Object_Management_Group | Object Management Group (OMG) is a consortium, originally aimed at setting standards for distributed object-oriented systems, and is now focused on modeling (programs, systems and business processes) and model-based standards. Overview OMG provide only specifications, and does not provide implementations. But before a specification can be accepted as a standard by OMG, the members of the winning submitter team must guarantee that they will bring a conforming product to market within a year. This is an attempt to prevent unimplemented (and unimplementable) standards. Other private companies or open source groups are encouraged to produce conforming products and OMG is attempting to develop mechanisms to enforcing true interoperability. History Founded in 1989 by eleven companies (including Hewlett-Packard, IBM, Sun Microsystems, Apple Computer, American Airlines and Data General), OMG tried to create a heterogeneous distributed object standard. The goal was a common portable and interoperable object model with methods and data that work using all types of development environments on all types of platforms. Today, over 800 companies from both the computer industry and software-using companies from other industries are members of OMG. Since 2000 the OMG's International Headquarters are located in Needham, Massachusetts. As of June 2006 the latest version of UML is 2.1, MOF is 2.0 and XMI is 2.1. In 2006 the BPMN language specification was adopted as a standard by OMG. In 2007 the Business Motivation Model (BMM) was adopted as a standard by the OMG. The BMM is a metamodel that provides a vocabulary for corporate governance and strategic planning and is particularly relevant to businesses undertaking governance, regulatory compliance, business transformation and strategic planning activities. OMG products Common Object Request Broker Architecture At its founding, OMG set out to create the initial Common Object Request Broker Architecture (CORBA) standard which appeared in 1991. As of 31 March 2003, the latest standard is CORBA 3.0. OMG has also developed a core set of standards adapting CORBA for embedded and real-time systems. Implementations of real time CORBA are widely used in control systems in ships and aircraft. Data Distribution Service Data Distribution Service for real-time systems (DDS) is a specification of a publish/subscribe middleware for distributed systems created in response to the need to augment CORBA with a data-centric publish-subscribe specification. As of December 2005 the latest standard is DDS 1.2, with version 1.3 currently available to OMG members. Model Driven Architecture OMG evolved towards modeling standards by creating the standard for Unified Modeling Language (UML) followed by related standards for Meta-Object Facility (MOF), XML Metadata Interchange (XMI) and MOF Query/Views/Transformation (QVT). These together provide the foundation for Model Driven Architecture (MDA), and related set of standards, building upon the success of UML and MOF. Systems Modeling Language (SysML), a modeling language based on UML for use in Systems Engineering, has been standardized in collaboration with INCOSE. Significant progress has also been made in bringing the world of UML modeling and the Semantic Web together through the adoption of the Ontology Definition Metamodel which relates UML models in a standard way with RDF and Web Ontology Language (OWL) models. Semantics of Business Vocabulary and Business Rules (SBVR) is a landmark for the OMG, the first OMG specification to incorporate the formal use of natural language in modeling and the first to provide explicitly a model of formal logic. Based on a fusion of linguistics, logic, and computer science, and two years in preparation, SBVR provides a way to capture specifications in natural language and represent them in formal logic so they can be machine-processed. SBVR is an integral part of MDA. Architecture Driven Modernization Architecture Driven Modernization (ADM} is the reverse of MDA. It also means Architecture Driven Modernization. ADMTF is an OMG group similar to ADTF with high potential. Knowledge Discovery Metamodel (KDM), a common intermediate representation for existing software systems and their operating environments. Knowledge Discovery Metamodel is designed as the OMG's foundation for software modernization and software assurance. Knowledge Discovery Metamodel uses Meta-Object Facility to define an XMI interchange format between tools that work with existing software and an abstract interface for the next-generation assurance and modernization tools. Abstract Syntax Tree Metamodel (ASTM), a modeling language for fine grained reverse engineering. Semantics of Business Vocabulary and Business Rules (SBVR) and KDM are designed as two parts of a unique OMG Technology Stack for software analytics related to existing software systems. KDM defines an ontology related to software artifacts and thus provides an initial formalization of the information related to a software system. SBVR is further used to formalize complex compliance rules related to the software. Domain models Business models : OMG manages a number of standards for business modeling, including BPMN, the Business Motivation Model (BMM) and the Semantics of Business Vocabulary and Business Rules (SBVR) specification. Verticals : Considerable progress has also been made in developing vertical model-based standards in the healthcare, finance, telecommunications, manufacturing, software-defined radio, space/ground systems communications and some dozen other technology areas. Software assurance and regulatory compliance New activities have been initiated to address important concerns of Regulatory Compliance and Software Assurance, building upon the base standards of MDA.

7,726 | Constantine_II_(emperor) | Flavius Claudius Constantinus, known in English as Constantine II, (316-340) was Roman Emperor from 337 to 340. The eldest son of Constantine the Great and Fausta, he was born at Arles, and was raised as a Christian. On March 1, 317, Constantine was made Caesar, and at the age of seven, in 323, took part in his father's campaign against the Sarmatians. At the age of ten he became commander of Gaul, after the death of his half-brother Crispus. An inscription dating to 330 records the title of Alamannicus, so it is probable that his generals won a victory over Alamanni. His military career continued when Constantine I elected his son field commander during the 332 campaign against the Goths. Coin of Constantine II Following the death of his father in 337, Constantine II became emperor jointly with his brothers Constantius II and Constans. After the division of the empire, made by the three brothers in September of the same year in Pannonia, he ruled over Gaul, Britannia and Hispania. He was involved in the struggle between the different Christian streams. The Western portion of the empire leaned towards Trinitarism and against Arianism, and Constantine freed Athanasius and allowed him to return to Alexandria. This action also put some burden on Constantius II, who was a supporter of Arianism. At first, he was the guardian of his younger brother Constans, whose portion was Italia, Africa and Illyricum. As Constans came of age, Constantine would not relinquish the guardianship and in 340 he marched against Constans in Italy, but was defeated at Aquileia and died in battle. Constans came to control his deceased brother's realm.

7,727 | Knock-knock_joke | The knock-knock joke is a type of joke, probably the best-known format of the pun, and is a time-honoured "call and answer" exercise. It is a roleplay exercise, with a punster and a recipient of wit. The standard format has five lines: The punster: Knock, knock! (indicating a door has been struck to gain attention) The recipient: Who's there? (an inquiry) The punster: a response, sometimes involving a name (to set up the pun) The recipient: a repetition of the response followed by who? (a request for clarification) The punster: the punch line, which typically involves a punnish misusage of the word set up during the response. Distribution and history Knock-knock jokes are well entrenched in the UK, Ireland, France, Belgium, Australia, the U.S.A., Canada, South Africa and India. In nations such as Brazil and Germany they are practically unknown. In French they begin "Toc-Toc" and in Afrikaans and Dutch "Klop-klop". In Spanish, it may be enough for the punchline to rhyme with the response. Knock-knock jokes were in common usage amongst South African school children in the early 1950s but the exact origin of the format remains uncertain. The following was in circulation in Cape Town in about 1953: Knock, knock! Who's there? Delores. Delores who? Delores my shepherd... (a play on "the Lord is my shepherd") In France, the punchline is almost always a pun on the title of a popular song, allowing the last answer to be sung : Toc Toc! (Knock knock!) Qui est là? (Who's there?) Sheila. Sheila qui? (Sheila who?) Sheila lutte finale... . (a pun on "c'est la lutte finale" (It's the final struggle), the opening line of The Internationale) In Shakespeare's play Macbeth a comic relief character delivers a 20 line monologue and satire that makes reference to events of that time it follows the pattern of knock knock who's there? but it is done entirely by the character and knocks from off stage. The character is a hung over porter (in most performances drunk, but in the original he was hung over) that pretends he is the porter to the gates of hell welcoming sinners of different professions: (Macbeth ActII, sciii) Knock, knock, knock! Who's there, i' th' name of Beelzebub? Here's a farmer that hanged himself on the expectation of plenty. Come in time, have napkins enough about you, here you'll sweat for 't. (this is a joke referring to a price drop in crops, as well as a joke about the heat in hell) Knock, knock! Who's there, in th' other devil's name? Faith, here's an equivocator that could swear in both the scales against either scale, who committed treason enough for God's sake, yet could not equivocate to heaven. O, come in, equivocator. (this passage is believed to be a reference to a trial of the Jesuits who were charged with equivocation speaking unclearly or speaking with double meaning) Knock, knock, knock! Who's there? Faith, here's an English tailor come hither for stealing out of a French hose. Come in, tailor. Here you may roast your goose. (the tailor is accused of stealing cloth while making breches, this is a joke about a fashion trend in Shakespearian times, also a pun for roasting the tailor's iron with the heat of hell) Multiple language knock-knock jokes In multiple language knock knock jokes, usually the third and fifth lines come in different languages, changing the complete perspective.

7,728 | Gemini_10 | Gemini 10 (officially Gemini X) was a 1966 manned spaceflight in NASA's Gemini program. It was the 8th manned Gemini flight, the 16th manned American flight and the 24th spaceflight of all time (includes X-15 flights over 100 km). Crew Number in parentheses indicates number of spaceflights by each individual prior to and including this mission. John W. Young (2) - Command Pilot Michael Collins (1) - Pilot Backup crew Alan L.

After docking with their Agena booster in low orbit, Young and Collins used it to climb another 763.8 kilometers to meet with the dead, drifting Agena left over from the aborted Gemini VIII flight-thus executing the program's first double rendezvous. With no electricity on board the second Agena the rendezvous was accomplished with eyes only - no radar. After the rendezvous, Collins space-walked over to the dormant Agena at the end of a 15.24 meter tether, making Collins the first person to meet another spacecraft in orbit. He retrieved a cosmic dustcollecting panel from the side of the Agena, but returned no pictures of his close encounter — in the complicated business of keeping his tether clear of the Gemini and Agena, Collins' Hasselblad camera worked itself free and drifted off into orbit. Gemini 10 was designed to achieve the objectives planned for the last two missions — rendezvous, docking and EVA. As well as this it was also hoped to dock with the Agena Target Vehicle from the Gemini 8 mission. This Agena's battery power had failed many months earlier and this would demonstrate the ability to rendezvous with a dormant object. It would be also the first mission to fire the Agena's own rocket, allowing them to reach higher orbits. Flight The Agena launched perfectly for the second time, after problems had occurred with the targets for Gemini 6 and 9. Gemini 10 followed 100 minutes later and entered into a 159.9 x 268.9 km orbit. They were 1800 km behind the Agena.

At first he mistook airglow as the real horizon when trying to make some fixes on stars. Then the image didn't seem right. He tried another instrument that they had on board but this was not practical to use at it had a very small field of view. They fortunately had a backup in the form of the computers on the ground. They made their first burn to put them into a 265 by 272 kilometres orbit. However Young didn't realise that during the next burn he had the spacecraft turned slightly which meant that they introduced an out of plane error. This meant two extra burns were necessary, and by the time they had docked with the Agena, 60% of their fuel had been consumed. It was decided to keep the Gemini docked to the Agena as long as possible as this would mean that they could use the fuel on board the Target Vehicle for attitude control. The first burn of the Agena engine they made was 80 seconds long and put them in a 294 by 763 kilometres orbit. This was the highest a person had ever been (until the next mission when Gemini 11 went to over 1000 km). This burn was quite a ride for the crew. Because the Gemini and Agena docked nose to nose, the forces experienced were "eyeballs out" as opposed to "eyeballs in" for a launch from Earth. The crew took a couple of pictures when they reached apogee but were more interested in what was going on in the spacecraft — checking the systems and watching the radiation dosage meter. After this they had their sleep period which lasted for eight hours and then they were ready for another busy day. First order of business was to make a second burn with the Agena engine to put them into the same orbit as the Gemini 8 Agena. This was at 20:58 UTC on 19 July and lasted 78 seconds and took 105 metres per second of their speed, putting them into a 294 by 382 km orbit. They made one more burn of the Agena to circularise their orbit to 377.6 km. EVA number 1 It was now time for the first of two EVAs on Gemini 10. This was to be just a standup EVA, where Collins would 'stand' in the open hatch and take some photographs of stars as part of experiment S-13. They used a 70 mm general purpose camera to image the Southern Milky Way in ultraviolet. After orbit sunrise, Collins then photographed a colour plate on the side of the spacecraft (MSC-8) to see whether film reproduced colours accurately in space. They reentered the spacecraft six minutes early when they both found their eyes were irritated. After repressurising they ran the oxygen at high rates and flushed the environment system. Young and Collins were both tired after the exercise of the EVA and slept well on their second 'night' in space. The next 'morning' they started preparing for the second rendezvous and another EVA. Rendezvous number 2 After undocking from their Agena they thought they sighted the Gemini 8 Agena. It however turned out to be their own Agena 5.5 km away, while their target was 176 km away. It wasn't until just over 30 km away that they saw it as a faint star. After a couple more correction burns they were station keeping 3 metres away. They found the Agena to be very stable and in good condition. EVA number 2 48 hours and 41 minutes into the mission, the second EVA began. Collins' first task was to retrieve a Micrometeorite Collector (S-12) from the side of the spacecraft. This he accomplished with some difficulty (like those experienced by Cernan on Gemini IX-A). However it floated out of the cabin some time during the rest of the EVA and was lost. He next travelled over to the Agena. He tried to grab onto the docking cone but found this impossible as it was smooth and had no grip. He used the gas gun to move himself towards the Gemini and then back to the Agena. This time he was able to grab hold of some wire bundles and retrieved the Micrometeorite Collector (S-10) from the Agena. He decided against replacing it as he could lose the one he had just retrieved. His last task on this EVA was to test out the gas gun. However this stopped working and meant they finished the EVA after only 25 minutes. It took the crew eight minutes to close the hatch as they had some difficulty with the 15 metres of umbilical cord. It was jettisoned along with the chestpack used by Collins an hour later when they opened the hatch for the third and final time. Experiments There were 10 other experiments that the crew performed during the mission. Three were interested in radiation. MSC-3 was the Tri-Axis Magnetometer which measured levels in the South Atlantic Anomaly. There was also MSC-6, a beta spectrometer, measured potential radiation doses for Apollo missions, and MSC-7, a bremsstrahlung spectrometer which detected radiation flux as a function of energy when the spacecraft passed through the South Atlantic Anomaly. S-26 was interested in the ion and electron wake of the spacecraft. This provided limited results due to the lack of fuel for attitude control, but found that electron and ion temperatures higher than expected and it registered shock effects during docking and undocking. Once again S-5 and S-6 were performed. These were Synoptic Terrain and Synoptic Weather photography respectively. Both had good results though were affected by the windows on the spacecraft being dirty. There was also S-1 which was intended to image the Zodiacal light. These were of little use as the film used was only half as sensitive as Gemini IX-A and the dirty windows lowered the transmission of light by a factor of six. They also tried to do D-5, a navigation experiment. They were only able to track 5 stars, with six needed for accurate measurements. The last experiment, D-10, was to investigate an Ion-sensing Attitude Control system. This was to try measuring the attitude of the spacecraft from the flow of ions and electrons around the spacecraft in orbit. This experiment showed the system to be accurate and responsive. Re-entry Splashdown of Gemini 10. The last day of the mission was short and retrofire came at 70 hours and 10 minutes into the mission. They landed only 5.6 km away from the intended landing site and were recovered by the USS Guadalcanal. The Gemini 10 mission was supported by the following U.S. Department of Defense resources; 9,067 personnel, 78 aircraft and 13 ships. Insignia The patch is simple in design but highly symbolic. The main feature is a large X with a Gemini and Agena orbiting around it. The two stars have a variety of meanings: the two rendezvous attempts, Castor and Pollux in Gemini or the two crew members. This is one of the few crew patches without the crew's name. It is also able to be displayed "upside down" but generally is shown with the spacecraft to the right. It was designed by Young's wife, Barbara. Although current NASA artwork shows the astronauts' names on the patch, the names were not on the version that flew. Spacecraft location For many years the spacecraft was the centerpiece of a space exhibition at Norsk Teknisk Museum, Oslo, Norway. It was returned on request in 2002. The spacecraft is currently on display at the Kansas Cosmosphere and Space Center, Hutchinson, Kansas. When the restoration of the Gemini 6A spacecraft is completed, then Gemini 10 will be restored in full view of the public. At the end of this restoration it will be put back on full display at the Cosmosphere. One of the hatches is displayed at Virginia Air and Space Center, Hampton, Virginia.

7,729 | Perfect_competition | In neoclassical economics and microeconomics, perfect competition describes the perfect being a market in which there are many small firms, all producing homogeneous goods. In the short term, such markets are productively inefficient as output will not occur where mc is equal to ac, but allocatively efficient, as output under perfect competition will always occur where mc is equal to mr, and therefore where mc equals ar. However, in the long term, such markets are both allocatively and productively efficient. Economics, Alain Anderton, 4th edition, p109 In general a perfectly competitive market is characterized by the fact that no single firm has influence on the price of the product it sells. Because the conditions for perfect competition are very strict, there are few perfectly competitive markets. A perfectly competitive market may have several distinguishing characteristics, including: Many buyers/Many Sellers – Many consumers with the willingness and ability to buy the product at a certain price, Many producers with the willingness and ability to supply the product at a certain price. Low-Entry/Exit Barriers – It is relatively easy to enter or exit as a business in a perfectly competitive market. Perfect Information - For both consumers and producers. perfect competition - the economics of competitive markets Firms Aim to Maximize Profits - Firms aim to sell where marginal costs meet marginal revenue, where they generate the most profit. Homogeneous Products – The characteristics of any given market good or service do not vary across suppliers. Some subset of these conditions is presented in most textbooks as defining perfect competition. More advanced textbooks (e.g. Mas-Colell et al. 1995 p. 315) try to reconcile these conditions with the definition of perfect competition as equilibrium price taking; that is whether or not firms treat price as a parameter or a choice variable. It is this distinction which differentiates perfectly competitive markets from imperfectly competitive ones. It should be noted that a general rigorous proof that the above conditions indeed suffice to guarantee price taking is still lacking (Kreps 1990, p. 265). The importance of perfect competition derives from the fact that price taking by the firm guarantees that when firms maximize profits (by choosing quantity they wish to produce, and the combination of Factors of production to produce it with) the market price will be equal to marginal cost. An implication of this is that a factor's price (wage, rent, etc.) equals the factor's marginal revenue product. This allows for derivation of the supply curve on which the neoclassical approach is based (note that this is also the reason why "a monopoly does not have a supply curve"). The abandonment of price taking creates considerable difficulties to the demonstration of existence of a general equilibrium (Roberts and Sonnenschein 1977) except under other, very specific conditions such as that of monopolistic competition . Approaches and conditions Historically, in neoclassical economics there have been two strands of looking at what perfect competition is. The first emphasis is on the inability of any one agent to affect prices. This is usually justified by the fact that any one firm or consumer is so small relative to the whole market that their presence or absence leaves the equilibrium price very nearly unaffected. This assumption of negligible impact of each agent on the equilibrium price has been formalized by Aumann (1964) by postulating a continuum of infinitesimal agents. The difference between Aumann’s approach and that found in undergraduate textbooks is that in the first, agents have the power to choose their own prices but do not individually affect the market price, while in the second it is simply assumed that agents treat prices as parameters. Both approaches lead to the same result. The second view of perfect competition conceives of it in terms of agents taking advantage of – and hence, eliminating – profitable exchange opportunities. The faster this arbitrage takes place, the more competitive a market is. The implication is that the more competitive a market is under this definition, the faster the average market price will adjust so as to equate supply and demand (and also equate price to marginal costs). In this view “perfect” competition means that this adjustment takes place instantaneously. This is usually modeled via the use of the Walrasian auctioneer (see article for more information). The widespread recourse to the auctioneer tale appears to have favored an interpretation of perfect competition as meaning price taking always, i.e. also at non-equilibrium prices; but this is rejected e.g. by Arrow (1959) or Mas-Colell et al. (1995, p. 315) Thus nowadays the dominant intuitive idea of the conditions justifying price taking and thus rendering a market perfectly competitive is an amalgam of several different notions, not all present, nor given equal weight, in all treatments. Besides product homogeneity and absence of collusion, the notion more generally associated with perfect competition is the negligibility of the size of agents, which makes them believe that they can sell as much of the good as they wish at the equilibrium price but nothing at a higher price (in particular, firms are described as each one of them facing a horizontal demand curve). However, also widely accepted as part of the notion of perfectly competitive market are perfect information about price distribution and very quick adjustments (whose joint operation establish the law of one price), to the point sometimes of identifying perfect competition with an essentially instantaneous reaching of equilibrium between supply and demand. Finally, the idea of free entry with free access to technology is also often listed as a characteristic of perfectly competitive markets, probably owing to a difficulty with abandoning completely the older conception of free competition. In recent decades it has been rediscovered that free entry can be a foundation of absence of market power, alternative to negligibility of agents (Novshek and Sonnenschein 1987.) Free entry also makes it easier to justify the absence of collusion: any collusion by existing firms can be undermined by entry of new firms. The necessarily long-period nature of the analysis (entry requires time!) also allows a reconciliation of the horizontal demand curve facing each firm according to the theory, with the feeling of businessmen that "contrary to economic theory, sales are by no means unlimited at the current market price" (Arrow 1959 p. 49). There are double the buyers in the market Results In the short-run, it is possible for an individual firm to make a profit. This situation is shown in this diagram, as the price or average revenue, denoted by P, is above the average cost denoted by C . However, in the long period, positive profit cannot be sustained. The arrival of new firms or expansion of existing firms (if returns to scale are constant) in the market causes the (horizontal) demand curve of each individual firm to shift downward, bringing down at the same time the price, the average revenue and marginal revenue curve. The final outcome is that, in the long run, the firm will make only normal profit (zero economic profit). Its horizontal demand curve will touch its average total cost curve at its lowest point. (See cost curve.) In a perfectly competitive market, a firm's demand curve is perfectly elastic. As mentioned above, the perfect competition model, if interpreted as applying also to short-period or very-short-period behaviour, is approximated only by markets of homogeneous products produced and purchased by very many sellers and buyers, usually organized markets for agricultural products or raw materials. In real-world markets, assumptions such as perfect information cannot be verified and are only approximated in organized double-auction markets where most agents wait and observe the behaviour of prices before deciding to exchange (but in the long-period interpretation perfect information is not necessary, the analysis only aims at determining the average around which market prices gravitate, and for gravitation to operate one does not need perfect information). In the absence of externalities and public goods, perfectly competitive equilibria are Pareto-efficient, i.e. no improvement in the utility of a consumer is possible without a worsening of the utility of some other consumer. This is called the First Theorem of Welfare Economics. The basic reason is that no productive factor with a non-zero marginal product is left unutilized, and the units of each factor are so allocated as to yield the same indirect marginal utility in all uses, a basic efficiency condition (if this indirect marginal utility were higher in one use than in other ones, a Pareto improvement could be achieved by transferring a small amount of the factor to the use where it yields a higher marginal utility). A simple proof assuming differentiable utility functions and production functions is the following. Let wj be the 'price' (the rental) of a certain factor j, let MPj1 and MPj2 be its marginal product in the production of goods 1 and 2, and let p1 and p2 be these goods' prices. In equilibrium these prices must equal the respective marginal costs MC1 and MC2; remember that marginal cost equals factor 'price' divided by factor marginal productivity (because increasing the production of good i by one very small unit through increase of the employment of factor j requires increasing the factor employment by 1/MPji and thus increasing the cost by wj/MPji, and through the condition of cost minimization that marginal products must be proportional to factor 'prices' it can be shown that the cost increase is the same if the output increase is obtained by optimally varying all factors). Optimal factor employment by a price-taking firm requires equality of factor rental and factor marginal revenue product, wj=piMPji, so we obtain p1=MC1=wj/MPj1, p2=MCj2=wj/MPj2. Now choose any consumer purchasing both goods, and measure his utility in such units that in equilibrium his marginal utility of money (the increase in utility due to the last unit of money spent on each good), MU1/p1=MU2/p2, is 1. Then p1=MU1, p2=MU2. The indirect marginal utility of the factor is the increase in the utility of our consumer achieved by an increase in the employment of the factor by one (very small) unit; this increase in utility through allocating the small increase in factor utilization to good 1 is MPj1MU1=MPj1p1=wj, and through allocating it to good 2 it is MPj2MU2=MPj2p2=wj again. With our choice of units the marginal utility of the amount of the factor consumed directly by the optimizing consumer is again w, so the amount supplied of the factor too satisfies the condition of optimal allocation. Monopoly violates this optimal allocation condition, because in a monopolized industry market price is above marginal cost, and this means that factors are underutilized in the monopolized industry, they have a higher indirect marginal utility than in their uses in competitive industries. Of course this theorem is considered irrelevant by economists who do not believe that general equilibrium theory correctly predicts the functioning of market economies; but it is given great importance by neoclassical economists and it is the theoretical reason given by them for combating monopolies and for antitrust legislation. Profit In contrast to a monopoly or oligopoly, it is impossible for a firm in perfect competition to earn economic profit in the long run, which is to say that a firm cannot make any more money than is necessary to cover its economic costs. In order not to misinterpret this zero-long-run-profits thesis, it must be remembered that the term 'profit' is also used in other ways. Neoclassical theory defines profit as what is left of revenue after all costs have been subtracted, including normal interest on capital plus the normal excess over it required to cover risk, and normal salary for managerial activity. Classical economists on the contrary defined profit as what is left after subtracting costs except interest and risk coverage; thus, if one leaves aside risk coverage for simplicity, the neoclassical zero-long-run-profit thesis would be re-expressed in classical parlance as profits coinciding with interest in the long period, i.e. the rate of profit tending to coincide with the rate of interest. Profits in the classical meaning do not tend to disappear in the long period but tend to normal profit. With this terminology, if a firm is earning abnormal profit in the short term, this will act as a trigger for other firms to enter the market. They will compete with the first firm, driving the market price down until all firms are earning normal profit only. It is important to note that perfect competition is a sufficient condition for allocative and productive efficiency, but it is not a necessary condition. Laboratory experiments in which participants have significant price setting power and little or no information about their counterparts consistently produce efficient results given the proper trading institutions (Smith, 1987, p. 245). The shutdown point When a firm is making a loss, it will have to decide whether to continue production or not. This decision will, in fact, depend on the different total costs levels and whether the firm is operating in the short run or in the long run. If the firm is in the short run, and is making a loss whereby: Total costs (TC) is greater than total revenue (TR) and whereby total revenue is greater than total variable cost (TVC) it is advisable for the firm to continue production. If it fails to achieve these conditions, it is advised to close down so that the only costs the firm will have to pay will be the fixed costs. Even if the firm stops producing, it will have to continue to meet the level of fixed costs. Since whether the firm produces or not, it will have to pay fixed costs, it is better for it to continue production in an attempt to decrease total costs and increase total revenue, thus making profits. This can be done by: Increasing productivity. The most obvious methods involve automation and computerization which minimize the tasks that must be performed by employees. All else constant, it benefits a business to improve productivity, which over time lowers cost and (hopefully) improves ability to compete and make profit. Adopting new methods of production like Just In Time or lean manufacturing in an attempt to reduce costs and wastages. In the long run, the condition to continue producing requires the price P to be higher than the ATC, i.e. the line representing market price should be above the minimum point of the ATC curve. If P is equal to ATC, the firm is indifferent between shutting down and continuing to produce. This case is different from the short run shut down case because in long run there's no longer a fixed cost (everything is variable). Examples Some agricultural markets, with numerous suppliers and almost perfectly substitutable products have been suggested as approximations for the perfect-competition model. The extent of its applicability may be dependent on the market in question. Agricultural policies in many countries undermine the requirements for complete Pareto efficiency to apply. Perhaps the closest thing to a perfectly competitive market would be a large auction of identical goods with all potential buyers and sellers present. By design, a stock exchange resembles this, not as a complete description (for no markets may satisfy all requirements of the model) but as an approximation. The flaw in considering the stock exchange as an example of Perfect Competition is the fact that large institutional investors (e.g. investment banks) may solely influence the market price. This, of course, violates the condition that "no one seller can influence market price". eBay auctions can be often seen as perfectly competitive. There are very low barriers to entry (anyone can sell a product, provided they have some knowledge of computers and the Internet), many sellers of common products and many potential buyers. Moreover, the buyers and sellers on ebay have (nearly) perfect information about the market, since they can quickly search and view all the other equivalent products on sale, and have exact information on price and product across the entire market at once. In the eBay market competitive advertising does not occur, because the products are homogeneous and this would be redundant. However, generic advertising (advertising which benefits the industry as a whole and does not mention any brand names) may occur. Free software works along lines that approximate perfect competition. Anyone is free to enter and leave the market at no cost. All code is freely accessible and modifiable, and individuals are free to behave independently. Free software may be bought or sold at whatever price that the market may allow. Some believe that one of the prime examples of a perfectly competitive market anywhere in the world is street food in developing countries. This is so since relatively few barriers to entry/exit exist for street vendors. Furthermore, there are often numerous buyers and sellers of a given street food, in addition to consumers/sellers possessing perfect information of the product in question. It is often the case that street vendors may serve a homogenous product, in which little to no variations in the product's nature exist. Criticisms The use of the assumption of perfect competition as the foundation of price theory for product markets is often criticized as representing all agents as passive, thus removing the active attempts to increase one's welfare or profits by price undercutting, product design, advertising, innovation, activities that - the critics argue - characterize most industries and markets. These criticisms point to the frequent lack of realism of the assumptions of product homogeneity and impossibility to differentiate it, but apart from this the accusation of passivity appears correct only for short-period or very-short-period analyses, in long-period analyses the inability of price to diverge from the natural or long-period price is due to active reactions of entry or exit. A frequent criticism is that it is often not true that in the short run differences between supply and demand cause changes in price; especially in manufacturing, the more common behaviour is alteration of production without nearly any alteration of price (Lee 1998). Anyway, the critics of the assumption of perfect competition in product markets seldom question the basic neoclassical view of the working of market economies for this reason. The Neo-Austrian school insists strongly on this criticism, and yet the neoclassical view of the working of market economies as fundamentally efficient, reflecting consumer choices and assigning to each agent his/her contribution to social welfare, is esteemed to be fundamentally correct (Kirzner 1981). Some non-neoclassical schools, like Post-Keynesians, reject the neoclassical approach to value and distribution, but not because of their rejection of perfect competition as a reasonable approximation to the working of most product markets; the reasons for rejection of the neoclassical 'vision' are different views of the determinants of income distribution and of aggregate demand (Petri 2004). In particular, the rejection of perfect competition does not generally entail the rejection of free competition as characterizing most product markets; indeed it has been argued (Clifton 1977) that competition is stronger nowadays than in 19th century capitalism, owing to the increasing capacity of big conglomerate firms to enter any industry: therefore the classical idea of a tendency toward a uniform rate of return on investment in all industries owing to free entry is even more valid to-day; and the reason why General Motors, Exxon or Nestle do not enter the computers or pharmaceutical industries is not insurmountable barriers to entry but rather that the rate of return in the latter industries is already sufficiently in line with the average rate of return elsewhere as not to justify entry. On this few economists, it would seem, would disagree, even among the neoclassical ones. Thus when the issue is normal, or long-period, product prices, differences on the validity of the perfect competition assumption do not appear to imply important differences on the existence or not of a tendency of rates of return toward uniformity as long as entry is possible, and what is found fundamentally lacking in the perfect competition model is the absence of marketing expenses and innovation as causes of costs that do enter normal average cost. The issue is different with respect to factor markets. Here the acceptance or denial of perfect competition in labour markets does make a big difference to the view of the working of market economies. One must distinguish neoclassical from non-neoclassical economists. For the former, absence of perfect competition in labour markets, e.g. due to the existence of trade unions, impedes the smooth working of competition, which if left free to operate would cause a decrease of wages as long as there were unemployment, and would finally ensure the full employment of labour: labour unemployment is due to absence of perfect competition in labour markets. Most non-neoclassical economists deny that a full flexibility of wages would ensure the full employment of labour and find a stickiness of wages an indispensable component of a market economy, without which the economy would lack the regularity and persistence indispensable to its smooth working. This was, for example, Keynes's opinion. Particularly radical is the view of the Sraffian school on this issue: the labour demand curve cannot be determined hence a level of wages ensuring the equality between supply and demand for labour does not exist, and economics should resume the viewpoint of the classical economists, according to whom competition in labour markets does not and cannot mean indefinite price flexibility as long as supply and demand are unequal, it only means a tendency to equality of wages for similar work, but the level of wages is necessarily determined by complex sociopolitical elements; custom, feelings of justice, informal allegiaces to classes, as well as overt coalitions such as trade unions, far from being impediments to a smooth working of labour markets that would be able to determine wages even without these elements, are on the contrary indispensable because without them there would be no way to determine wages (Garegnani 1990).

7,730 | Comet | Comet Hale-Bopp, as seen on 29 March 1997 in Pazin, Croatia. A comet is a Small Solar System Body that orbits the Sun. When close enough to the Sun, a comet exhibits a visible coma (fuzzy "atmosphere"), and sometimes a tail, both because of the effects of solar radiation upon the comet's nucleus. Comet nuclei are themselves loose collections of ice, dust and small rocky particles, ranging from a few kilometers to tens of kilometers across. Background Name and symbol The word comet came to the English language through the Latin cometes from the Greek word komē, meaning "hair of the head"; Aristotle first used the derivation komētēs to depict comets as "stars with hair." The astronomical symbol for comets () accordingly consists of a disc with a hairlike tail. Orbits and origin Comets have a variety of different orbital periods, ranging from a few years, to hundreds of thousands of years, while some are believed to pass only once through the inner Solar System before being thrown out into interstellar space. Short-period comets are thought to originate in the Kuiper Belt, or associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are believed to originate in the Oort cloud, consisting of debris left over from the condensation of the solar nebula, located well-beyond the Kuiper Belt. Comets are thrown from these outer reaches of the Solar System towards the Sun by gravitational perturbations from the outer planets (in the case of Kuiper Belt objects) or nearby stars (in the case of Oort Cloud objects), or as a result of collisions between objects within these regions. Comets are distinguished from asteroids by the presence of a coma or tail, though very old comets that have lost all their volatile materials may come to resemble asteroids (see extinct comets). Asteroids are also believed to have a different origin from comets, having formed in the inner Solar System rather than the outer Solar System, but recent findings have somewhat blurred the distinction between asteroids and comets (see centaurs and asteroid terminology). there are a reported 3,648 known comets of which about 1500 are Kreutz Sungrazers and about 400 are short-period. This number is steadily increasing. However, this represents only a tiny fraction of the total potential comet population: the reservoir of comet-like bodies in the outer solar system may number one trillion. The number of comets visible to the naked-eye averages to roughly one per year, though many of these are faint and unspectacular. When a historically bright or notable naked-eye comet is witnessed by many people, it may be termed a Great Comet. Physical characteristics Nucleus Nucleus of comet Tempel 1 imaged by the Deep Impact impactor. The nucleus measures about 6 kilometres across. Comet Hyakutake Comet Holmes (17P/Holmes) in 2007 showing blue ion tail on right Comet nuclei are known to range from about 100 meters to more than 40 kilometers across. They are composed of rock, dust, water ice, and frozen gases such as carbon monoxide, carbon dioxide, methane and ammonia. They are often popularly described as "dirty snowballs", though recent observations have revealed dry dusty or rocky surfaces, suggesting that the ices are hidden beneath the crust (see Debate over comet composition). Comets also contain a variety of organic compounds; in addition to the gases already mentioned, these may include methanol, hydrogen cyanide, formaldehyde, ethanol and ethane, and perhaps more complex molecules such as long-chain hydrocarbons and amino acids. Because of their low mass, comets cannot become spherical under their own gravity, and will thus have irregular shapes. Surprisingly, cometary nuclei are among the darkest objects known to exist in the solar system. The Giotto probe found that Comet Halley's nucleus reflects approximately 4% of the light that falls on it, and Deep Space 1 discovered that Comet Borrelly's surface reflects 2.4–3.0% of the light that falls on it; by comparison, asphalt reflects 7% of the light that falls on it. It is thought that complex organic compounds are the dark surface material. Solar heating drives off volatile compounds leaving behind heavy long-chain organics that tend to be very dark, like tar or crude oil. The very darkness of cometary surfaces allows them to absorb the heat necessary to drive their outgassing. Coma and tail In the outer solar system, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from the Hubble Space Telescope observations, but these detections have been questioned, and have not yet been independently confirmed. As a comet approaches the inner solar system, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous tail to form, which points away from the sun. Both the coma and tail are illuminated by the Sun and may become visible from Earth when a comet passes through the inner solar system, the dust reflecting sunlight directly and the gases glowing from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. Occasionally a comet may experience a huge and sudden outburst of gas and dust, during which the size of the coma temporarily greatly increases in size. This happened in 2007 to Comet Holmes. The streams of dust and gas each form their own distinct tail, pointing in slightly different directions. The tail of dust is left behind in the comet's orbit in such a manner that it often forms a curved tail called the antitail. At the same time, the ion tail, made of gases, always points directly away from the Sun, as this gas is more strongly affected by the solar wind than is dust, following magnetic field lines rather than an orbital trajectory. Parallax viewing from the Earth may sometimes mean the tails appear to point in opposite directions. While the solid nucleus of comets is generally less than 50 km across, the coma may be larger than the Sun, and ion tails have been observed to extend 1 astronomical unit (150 million km) or more. The observation of antitails contributed significantly to the discovery of solar wind. The ion tail is formed as a result of the photoelectric effect of solar ultra-violet radiation acting on particles in the coma. Once the particles have been ionised, they attain a net positive electrical charge which in turn gives rise to an "induced magnetosphere" around the comet. The comet and its induced magnetic field form an obstacle to outward flowing solar wind particles. As the relative orbital speed of the comet and the solar wind is supersonic a bow shock is formed upstream of the comet, in the flow direction of the solar wind. In this bow shock, large concentrations of cometary ions (called "pick-up ions") congregate and act to "load" the solar magnetic field with plasma, such that the field lines "drape" around the comet forming the ion tail. Comet Encke loses its tail If the ion tail loading is sufficient, then the magnetic field lines are squeezed together to the point where, at some distance along the ion tail, magnetic reconnection occurs. This leads to a "tail disconnection event". This has been observed on a number of occasions, notable among which was on the 20th. April 2007 when the ion tail of comet Encke was completely severed as the comet passed through a coronal mass ejection. This event was observed by the STEREO spacecraft. Comets were found to emit X-rays in 1996. This surprised researchers, because X-ray emission is usually associated with very high-temperature bodies. The X-rays are thought to be generated by the interaction between comets and the solar wind: when highly charged ions fly through a cometary atmosphere, they collide with cometary atoms and molecules, "ripping of" one or more electrons from the comet. This ripping off would leads to the emission of X-rays and far ultraviolet photons. Connection to meteor showers As a result of outgassing, comets leave a trail of solid debris behind them. If the comet's path crosses Earth's path, then at that point there will likely be meteor showers as Earth passes through the trail of debris. The Perseid meteor shower occurs every year between August 9 and August 13, when Earth passes through the orbit of the Swift–Tuttle comet. Halley's comet is the source of the Orionid shower in October. The fate of comets Departure/Ejection from Solar System If a comet is traveling fast enough, it will enter and leave the solar system, such is the case for most non-periodic comets. In addition, comets can be ejected by interacting with another object in the solar system (see Perturbation), such as with Jupiter. Volatiles exhausted Material coming off Component B of 73P/Schwassmann-Wachmann which broke up starting in 1995, as seen by the HST. Jupiter family comets (JFC) and long period comets (LPC) (see "Orbital characteristics", below) appear to follow very different fading laws. The JFCs are active over a lifetime of about 10,000 years or ~1,000 revolutions while the LPCs disappear much faster. Only 10% of the LPCs survive more than 50 passages to small perihelion, while only 1% of them survives more than 2,000 passages. Eventually most of the volatile material contained in a comet nucleus evaporates away, and the comet becomes a small, dark, inert lump of rock or rubble that can resemble an asteroid. Breakups/Disintegration Comets are also known to break up into fragments, as happened with Comet 73P/Schwassmann-Wachmann 3 starting in 1995. This breakup may be triggered by tidal gravitational forces from the Sun or a large planet, by an "explosion" of volatile material, or for other reasons not fully explained. Collisions Shoemaker-Levy 9 was broken up by tidal forces shortly before colliding with Jupiter Some comets meet a more spectacular end—either falling into the Sun, or smashing into a planet or other body. Collisions between comets and planets or moons were common in the early Solar System: some of the many craters on the Earth's Moon, for example, may have been caused by comets. A recent collision of a comet with a planet occurred in 1994 when Comet Shoemaker-Levy 9 broke up into pieces and collided with Jupiter. Many comets and asteroids collided into Earth in its early stages. Many scientists believe that comets bombarding the young Earth (about 4 billion years ago) brought the vast quantities of water that now fill the Earth's oceans, or at least a significant proportion of it. But other researchers have cast doubt on this theory. The detection of organic molecules in comets has led some to speculate that comets or meteorites may have brought the precursors of life—or even life itself—to Earth. There are still many near-Earth comets, although a collision with an asteroid is more likely than with a comet. It is suspected that comet impacts have, over long timescales, also delivered significant quantities of water to the Earth's Moon, some of which may have survived as lunar ice. Orbital characteristics Orbits of Comet Kohoutek (red) and Earth (blue), illustrating the high eccentricity of the orbit and more rapid motion when closer to the Sun. Histogram of the aphelia of the 2005 comets, showing the giant planet comet families. The abscissa is the natural logarithm of the aphelion expressed in AUs. Most comets have elongated elliptical orbits (oval shaped) that take them close to the Sun for a part of their orbit, and then out into the further reaches of the Solar System for the remainder. Comets are often classified according to the length of their orbital period; the longer the period the more elongated the ellipse. Short-period comets are generally defined as having orbital periods of less than 200 years. They usually orbit more-or-less in the ecliptic plane in the same direction as the planets. Their orbits typically take them out to the region of the outer planets (Jupiter and beyond) at aphelion; for example, Comet Halley's aphelion is a little way beyond the orbit of Neptune. At the shorter extreme, Comet Encke has an orbit which never places it farther from the Sun than Jupiter. Short-period comets are further divided into the Jupiter family (periods less than 20 years) and Halley family (periods between 20 and 200 years). Long-period comets have highly eccentric (elongated) orbits and periods ranging from 200 years to thousands or even millions of years. (However, by definition they remain gravitationally bound to the Sun; those comets that are ejected from the solar system due to close passes by major planets are no longer properly considered as having "periods".) Their orbits take them far beyond the outer planets at aphelia, and the plane of their orbits need not lie near the ecliptic. Single-apparition comets are similar to long-period comets, but have parabolic or hyperbolic trajectories which will cause them to permanently exit the solar system after passing the Sun once. Some authorities use the term periodic comet to refer to any comet with a periodic orbit (that is, all short-period comets plus all long-period comets), while others use it to mean exclusively short-period comets. Similarly, although the literal meaning of non-periodic comet is the same as single-apparition comet, some use it to mean all comets that are not "periodic" in the second sense (that is, to also include all comets with a period greater than 200 years). Recently discovered main-belt comets form a distinct class, orbiting in more circular orbits within the asteroid belt. IAU bulletin IB74 Based on their orbital characteristics, short-period comets are thought to originate from the centaurs and the Kuiper belt/scattered disk—a disk of objects in the transneptunian region—whereas the source of long-period comets is thought to be the far more distant spherical Oort cloud (after the Dutch astronomer Jan Hendrik Oort who hypothesised its existence). Vast swarms of comet-like bodies are believed to orbit the Sun in these distant regions in roughly circular orbits. Occasionally the gravitational influence of the outer planets (in the case of Kuiper Belt objects) or nearby stars (in the case of Oort cloud objects) may throw one of these bodies into an elliptical orbit that takes it inwards towards the Sun, to form a visible comet. Unlike the return of periodic comets whose orbits have been established by previous observations, the appearance of new comets by this mechanism is unpredictable. Since their elliptical orbits frequently take them close to the giant planets, comets are subject to further gravitational perturbations. Short period comets display a tendency for their aphelia to coincide with a giant planet's orbital radius, with the Jupiter family of comets being the largest, as the histogram shows. It is clear that comets coming in from the Oort cloud often have their orbits strongly influenced by the gravity of giant planets as a result of a close encounter. Jupiter is the source of the greatest perturbations, being more than twice as massive as all the other planets combined, in addition to being the swiftest of the giant planets. These perturbations may sometimes deflect long-period comets into shorter orbital periods (Halley's Comet being a possible example). Early observations have revealed a few genuinely hyperbolic (i.e. non-periodic) trajectories, but no more than could be accounted for by perturbations from Jupiter. If comets pervaded interstellar space, they would be moving with velocities of the same order as the relative velocities of stars near the Sun (a few tens of kilometres per second). If such objects entered the solar system, they would have positive total energies, and would be observed to have genuinely hyperbolic trajectories. A rough calculation shows that there might be four hyperbolic comets per century, within Jupiter's orbit, give or take one and perhaps two orders of magnitude. A number of periodic comets discovered in earlier decades or previous centuries are now "lost." Their orbits were never known well enough to predict future appearances. However, occasionally a "new" comet will be discovered and upon calculation of its orbit it turns out to be an old "lost" comet. An example is Comet 11P/Tempel-Swift-LINEAR, discovered in 1869 but unobservable after 1908 because of perturbations by Jupiter. It was not found again until accidentally rediscovered by LINEAR in 2001. Comet nomenclature The names given to comets have followed several different conventions over the past two centuries. Before any systematic naming convention was adopted, comets were named in a variety of ways. Prior to the early 20th century, most comets were simply referred to by the year in which they appeared, sometimes with additional adjectives for particularly bright comets; thus, the "Great Comet of 1680" (Kirch's Comet), the "Great September Comet of 1882," and the "Daylight Comet of 1910" ("Great January Comet of 1910"). After Edmund Halley demonstrated that the comets of 1531, 1607, and 1682 were the same body and successfully predicted its return in 1759, that comet became known as Comet Halley. Similarly, the second and third known periodic comets, Comet Encke and Comet Biela, were named after the astronomers who calculated their orbits rather than their original discoverers. Later, periodic comets were usually named after their discoverers, but comets that had appeared only once continued to be referred to by the year of their apparition. In the early 20th century, the convention of naming comets after their discoverers became common, and this remains so today. A comet is named after up to three independent discoverers. In recent years, many comets have been discovered by instruments operated by large teams of astronomers, and in this case, comets may be named for the instrument. For example, Comet IRAS-Araki-Alcock was discovered independently by the IRAS satellite and amateur astronomers Genichi Araki and George Alcock. In the past, when multiple comets were discovered by the same individual, group of individuals, or team, the comets' names were distinguished by adding a numeral to the discoverers' names (but only for periodic comets); thus Comets Shoemaker-Levy 1–9. Today, the large numbers of comets discovered by some instruments has rendered this system impractical, and no attempt is made to ensure that each comet has a unique name. Instead, the comets' systematic designations are used to avoid confusion. Until 1994, comets were first given a provisional designation consisting of the year of their discovery followed by a lowercase letter indicating its order of discovery in that year (for example, Comet 1969i (Bennett) was the 9th comet discovered in 1969). Once the comet had been observed through perihelion and its orbit had been established, the comet was given a permanent designation of the year of its perihelion, followed by a Roman numeral indicating its order of perihelion passage in that year, so that Comet 1969i became Comet 1970 II (it was the second comet to pass perihelion in 1970) Increasing numbers of comet discoveries made this procedure awkward, and in 1994 the International Astronomical Union approved a new naming system. Comets are now designated by the year of their discovery followed by a letter indicating the half-month of the discovery and a number indicating the order of discovery (a system similar to that already used for asteroids), so that the fourth comet discovered in the second half of February 2006 would be designated 2006 D4. Prefixes are also added to indicate the nature of the comet: P/ indicates a periodic comet (defined for these purposes as any comet with an orbital period of less than 200 years or confirmed observations at more than one perihelion passage); C/ indicates a non-periodic comet (defined as any comet that is not periodic according to the preceding definition); X/ indicates a comet for which no reliable orbit could be calculated (generally, historical comets); D/ indicates a comet which has broken up or been lost, referred to as dark comet; A/ indicates an object that was mistakenly identified as a comet, but is actually a minor planet. After their second observed perihelion passage, periodic comets are also assigned a number indicating the order of their discovery. So Halley's Comet, the first comet to be identified as periodic, has the systematic designation 1P/1682 Q1. Comet Hale-Bopp's designation is C/1995 O1. Comets which first received a minor planet designation keep the latter, which leads to some odd names such as (Catalina-LINEAR). There are only five objects that are cross-listed as both comets and asteroids: 2060 Chiron (95P/Chiron), 4015 Wilson-Harrington (107P/Wilson-Harrington), 7968 Elst-Pizarro (133P/Elst-Pizarro), 60558 Echeclus (174P/Echeclus), and 118401 LINEAR (176P/LINEAR). History of comet study Early observations and thought Comet Halley depicted on the Bayeux Tapestry which shows King Harold I being told of Halley's Comet before the Battle of Hastings in 1066. Before the invention of the telescope, comets seemed to appear out of nowhere in the sky and gradually vanish out of sight. They were usually considered bad omens of deaths of kings or noble men, or coming catastrophes, or even interpreted as attacks by heavenly beings against terrestrial inhabitants. From ancient sources, such as Chinese oracle bones, it is known that their appearances have been noticed by humans for millennia. Some authorities interpret references to "falling stars" in Gilgamesh, the Book of Revelation and the Book of Enoch as references to comets, or possibly bolides. In the first book of his Meteorology, Aristotle propounded the view of comets that would hold sway in Western thought for nearly two thousand years. He rejected the ideas of several earlier philosophers that comets were planets, or at least a phenomenon related to the planets, on the grounds that while the planets confined their motion to the circle of the Zodiac, comets could appear in any part of the sky. Instead, he described comets as a phenomenon of the upper atmosphere, where hot, dry exhalations gathered and occasionally burst into flame. Aristotle held this mechanism responsible for not only comets, but also meteors, the aurora borealis, and even the Milky Way. A few later classical philosophers did dispute this view of comets. Seneca the Younger, in his Natural Questions, observed that comets moved regularly through the sky and were undisturbed by the wind, behavior more typical of celestial than atmospheric phenomena. While he conceded that the other planets do not appear outside the Zodiac, he saw no reason that a planet-like object could not move through any part of the sky, humanity's knowledge of celestial things being very limited. However, the Aristotelian viewpoint proved more influential, and it was not until the 16th century that it was demonstrated that comets must exist outside the Earth's atmosphere. In 1577, a bright comet was visible for several months. The Danish astronomer Tycho Brahe used measurements of the comet's position taken by himself and other, geographically separated, observers to determine that the comet had no measurable parallax. Within the precision of the measurements, this implied the comet must be at least four times more distant from the earth than the moon. One very famous old recording of a comet is the appearance of Halley's Comet on the Bayeux Tapestry, which records the Norman conquest of England in AD 1066. Orbital studies The orbit of the comet of 1680, fit to a parabola, as shown in Isaac Newton's Principia Although comets had now been demonstrated to be in the heavens, the question of how they moved through the heavens would be debated for most of the next century. Even after Johannes Kepler had determined in 1609 that the planets moved about the sun in elliptical orbits, he was reluctant to believe that the laws that governed the motions of the planets should also influence the motion of other bodies—he believed that comets travel among the planets along straight lines. Galileo Galilei, although a staunch Copernicanist, rejected Tycho's parallax measurements and held to the Aristotelian notion of comets moving on straight lines through the upper atmosphere. The first suggestion that Kepler's laws of planetary motion should also apply to the comets was made by William Lower in 1610. In the following decades other astronomers, including Pierre Petit, Giovanni Borelli, Adrien Auzout, Robert Hooke, Johann Baptist Cysat, and Giovanni Domenico Cassini all argued for comets curving about the sun on elliptical or parabolic paths, while others, such as Christian Huygens and Johannes Hevelius, supported comets' linear motion. The matter was resolved by the bright comet that was discovered by Gottfried Kirch on November 14, 1680. Astronomers throughout Europe tracked its position for several months. In 1681, the Saxon pastor Georg Samuel Doerfel set forth his proofs that comets are heavenly bodies moving in parabolas of which the sun is the focus. Then Isaac Newton, in his Principia Mathematica of 1687, proved that an object moving under the influence of his inverse square law of universal gravitation must trace out an orbit shaped like one of the conic sections, and he demonstrated how to fit a comet's path through the sky to a parabolic orbit, using the comet of 1680 as an example. In 1705, Edmond Halley applied Newton's method to twenty-three cometary apparitions that had occurred between 1337 and 1698. He noted that three of these, the comets of 1531, 1607, and 1682, had very similar orbital elements, and he was further able to account for the slight differences in their orbits in terms of gravitational perturbation by Jupiter and Saturn. Confident that these three apparitions had been three appearances of the same comet, he predicted that it would appear again in 1758–9. (Earlier, Robert Hooke had identified the comet of 1664 with that of 1618, while Jean-Dominique Cassini had suspected the identity of the comets of 1577, 1665, and 1680. Both were incorrect.) Halley's predicted return date was later refined by a team of three French mathematicians: Alexis Clairaut, Joseph Lalande, and Nicole-Reine Lepaute, who predicted the date of the comet's 1759 perihelion to within one month's accuracy. When the comet returned as predicted, it became known as Comet Halley or Halley's Comet (its official designation is 1P/Halley). Its next appearance will be in 2061. Among the comets with short enough periods to have been observed several times in the historical record, Comet Halley is unique in consistently being bright enough to be visible to the naked eye. Since the confirmation of Comet Halley's periodicity, many other periodic comets have been discovered through the telescope. The second comet to be discovered to have a periodic orbit was Comet Encke (official designation 2P/Encke). Over the period 1819–1821 the German mathematician and physicist Johann Franz Encke computed orbits for a series of cometary apparitions observed in 1786, 1795, 1805, and 1818, concluded that they were same comet, and successfully predicted its return in 1822. By 1900, seventeen comets had been observed at more than one perihelion passage and recognized as periodic comets. As of April 2006, 175 comets have achieved this distinction, though several have since been destroyed or lost. In ephemerides, comets are often denoted by the symbol . Studies of physical characteristics Comets have highly elliptical orbits. Note the two distinct tails:Cyan for gas tail, grey for dust tail Isaac Newton described comets as compact and durable solid bodies moving in oblique orbits, and their tails as thin streams of vapor emitted by their nuclei, ignited or heated by the sun. Newton suspected that comets were the origin of the life-supporting component of air. Newton also believed that the vapors given off by comets might replenish the planets' supplies of water (which was gradually being converted into soil by the growth and decay of plants), and the sun's supply of fuel. As early as the 18th century, some scientists had made correct hypotheses as to comets' physical composition. In 1755, Immanuel Kant hypothesized that comets are composed of some volatile substance, whose vaporization gives rise to their brilliant displays near perihelion. In 1836, the German mathematician Friedrich Wilhelm Bessel, after observing streams of vapor in the 1835 apparition of Comet Halley, proposed that the jet forces of evaporating material could be great enough to significantly alter a comet's orbit and argued that the non-gravitational movements of Comet Encke resulted from this mechanism. However, another comet-related discovery overshadowed these ideas for nearly a century. Over the period 1864–1866 the Italian astronomer Giovanni Schiaparelli computed the orbit of the Perseid meteors, and based on orbital similarities, correctly hypothesized that the Perseids were fragments of Comet Swift-Tuttle. The link between comets and meteor showers was dramatically underscored when in 1872, a major meteor shower occurred from the orbit of Comet Biela, which had been observed to split into two pieces during its 1846 apparition, and was never seen again after 1852. A "gravel bank" model of comet structure arose, according to which comets consist of loose piles of small rocky objects, coated with an icy layer. By the middle of the twentieth century, this model suffered from a number of shortcomings: in particular, it failed to explain how a body that contained only a little ice could continue to put on a brilliant display of evaporating vapor after several perihelion passages. In 1950, Fred Lawrence Whipple proposed that rather than being rocky objects containing some ice, comets were icy objects containing some dust and rock. This "dirty snowball" model soon became accepted. It was confirmed when an armada of spacecraft (including the European Space Agency's Giotto probe and the Soviet Union's Vega 1 and Vega 2) flew through the coma of Halley's comet in 1986 to photograph the nucleus and observed the jets of evaporating material (though see also "Debate over comet composition", below). The American probe Deep Space 1 flew past the nucleus of Comet Borrelly on September 21, 2001 and confirmed that the characteristics of Comet Halley are common on other comets as well. Although comets formed in the outer Solar System, radial mixing of material during the early formation of the Solar System is thought to have redistributed material throughout the proto-planetary disk, so comets also contain crystalline grains which were formed in the hot inner Solar System. This is seen in comet spectra as well as in sample return missions. Comet Wild 2 exhibits jets on light side and dark side, stark relief, and is dry. The Stardust spacecraft, launched in February 1999, collected particles from the coma of Comet Wild 2 in January 2004, and returned the samples to Earth in a capsule in January 2006. Claudia Alexander, a program scientist for Rosetta from NASA's Jet Propulsion Laboratory who has modeled comets for years, reported to space.com about her astonishment at the number of jets, their appearance on the dark side of the comet as well as on the light side, their ability to lift large chunks of rock from the surface of the comet and the fact that comet Wild 2 is not a loosely cemented rubble pile. Forthcoming space missions will add greater detail to our understanding of what comets are made of. In July 2005, the Deep Impact probe blasted a crater on Comet Tempel 1 to study its interior. And in 2014, the European Rosetta probe will orbit Comet Churyumov-Gerasimenko and place a small lander on its surface. Rosetta observed the Deep Impact event, and with its set of very sensitive instruments for cometary investigations, it used its capabilities to observe Tempel 1 before, during and after the impact. At a distance of about 80 million kilometres from the comet, Rosetta was the only spacecraft other than Deep Impact itself to view the comet. Debate over comet composition Comet Borrelly exhibits jets, yet is hot and dry. Debate continues about how much ice is in a comet. In 2001, NASA's Deep Space 1 team, working at NASA's Jet Propulsion Lab, obtained high-resolution images of the surface of Comet Borrelly. They announced that comet Borrelly exhibits distinct jets, yet has a hot, dry surface. The assumption that comets contain water and other ices led Dr. Laurence Soderblom of the U.S. Geological Survey to say, "The spectrum suggests that the surface is hot and dry. It is surprising that we saw no traces of water ice." However, he goes on to suggest that the ice is probably hidden below the crust as "either the surface has been dried out by solar heating and maturation or perhaps the very dark soot-like material that covers Borrelly's surface masks any trace of surface ice". The recent Deep Impact probe has also yielded results suggesting that the majority of a comet's water ice is below the surface, and that these reservoirs feed the jets of vaporised water that form the coma of Tempel 1. However, more recent data from the Stardust mission show that materials retrieved from the tail of comet Wild 2 were crystalline and could only have been "born in fire." More recent still, the materials retrieved demonstrate that the "comet dust resembles asteroid materials." These new results have forced scientists to rethink the nature of comets and their distinction from asteroids. Notable comets Great comets While hundreds of tiny comets pass through the inner solar system every year, very few are noticed by the general public. About every decade or so, a comet will become bright enough to be noticed by a casual observer—such comets are often designated Great Comets. In times past, bright comets often inspired panic and hysteria in the general population, being thought of as bad omens. More recently, during the passage of Halley's Comet in 1910, the Earth passed through the comet's tail, and erroneous newspaper reports inspired a fear that cyanogen in the tail might poison millions, while the appearance of Comet Hale-Bopp in 1997 triggered the mass suicide of the Heaven's Gate cult. To most people, however, a great comet is simply a beautiful spectacle. Predicting whether a comet will become a great comet is notoriously difficult, as many factors may cause a comet's brightness to depart drastically from predictions. Broadly speaking, if a comet has a large and active nucleus, will pass close to the Sun, and is not obscured by the Sun as seen from the Earth when at its brightest, it will have a chance of becoming a great comet. However, Comet Kohoutek in 1973 fulfilled all the criteria and was expected to become spectacular, but failed to do so. Comet West, which appeared three years later, had much lower expectations (perhaps because scientists were much warier of glowing predictions after the Kohoutek fiasco), but became an extremely impressive comet. The late 20th century saw a lengthy gap without the appearance of any great comets, followed by the arrival of two in quick succession—Comet Hyakutake in 1996, followed by Hale-Bopp, which reached maximum brightness in 1997 having been discovered two years earlier. The first great comet of the 21st century was Comet McNaught, which became visible to naked eye observers in January 2007. It was the brightest in over 40 years. Sungrazing comets The Great Comet of 1882, is a member of the Kreutz group A Sungrazing comet is a comet that passes extremely close to the Sun at perihelion, sometimes within a few thousand kilometres of the Sun's surface. While small sungrazers can be completely evaporated during such a close approach to the Sun, larger sungrazers can survive many perihelion passages. However, the strong tidal forces they experience often lead to their fragmentation. About 90% of the sungrazers observed with SOHO are members of the Kreutz group, which all originate from one giant comet that broke up into many smaller comets during its first passage through the inner solar system. The other 10% contains some sporadic sungrazers, but four other related groups of comets have been identified among them: the Kracht, Kracht 2a, Marsden and Meyer groups. The Marsden and Kracht groups both appear to be related to Comet 96P/Machholz, which is also the parent of two meteor streams, the Quadrantids and the Arietids. Unusual comets The quasi-circular orbit of 29P/Schwassmann-Wachmann compared to Jupiter and Saturn. Of the thousands of known comets, some are very unusual. Comet Encke orbits from outside the main asteroid belt to inside the orbit of Mercury while Comet 29P/Schwassmann-Wachmann currently travels in a nearly circular orbit entirely between Jupiter and Saturn. 2060 Chiron, whose unstable orbit is between Saturn and Uranus, was originally classified as an asteroid until a faint coma was noticed. Similarly, Comet Shoemaker-Levy 2 was originally designated asteroid . Roughly six percent of the near-earth asteroids are thought to be extinct nuclei of comets which no longer experience outgassing. Some comets have been observed to break up during their perihelion passage, including great comets West and Ikeya-Seki. Comet Biela was one significant example, breaking into two during its 1846 perihelion passage. The two comets were seen separately in 1852, but never again afterward. Instead, spectacular meteor showers were seen in 1872 and 1885 when the comet should have been visible. A lesser meteor shower, the Andromedids, occurs annually in November, and is caused by the Earth crossing Biela's orbit. Another significant cometary disruption was that of Comet Shoemaker-Levy 9, which was discovered in 1993. At the time of its discovery, the comet was in orbit around Jupiter, having been captured by the planet during a very close approach in 1992. This close approach had already broken the comet into hundreds of pieces, and over a period of 6 days in July 1994, these pieces slammed into Jupiter's atmosphere—the first time astronomers had observed a collision between two objects in the solar system. It has also been suggested that the object likely to have been responsible for the Tunguska event in 1908 was a fragment of Comet Encke. Observation Example of a comet's path plotted by planetarium software (Sky Map Pro) A new comet may be discovered photographically using a wide-field telescope or visually with binoculars. However, even without access to optical equipment, it is still possible for the amateur astronomer to discover a Sun-grazing comet online by downloading images accumulated by some satellite observatories such as SOHO. Comets visible to the naked eye are fairly infrequent, but comets that put on fine displays in amateur class telescopes (50 mm to 100 cm) occur fairly often—as often as several times a year, occasionally with more than one in the sky at the same time. Commonly available astronomical software will plot the orbits of these known comets. They are fast compared to other objects in the sky, but their movement is usually subtle in the eyepiece of a telescope. However, from night to night, they can move several degrees, which is why observers find it useful to have a sky chart such as the one in the adjoining illustration. The type of display presented by the comet depends on its composition and how close it comes to the sun. Because the volatility of a comet's material decreases as it gets further from the sun, the comet becomes increasingly difficult to observe as a function of not only distance, but the progressive shrinking and eventual disappearance of its tail and the reflective elements it carries. Comets are most interesting when their nucleus is bright and they display a long tail, which to be seen sometimes requires a large field of view best provided by smaller telescopes. Therefore, large amateur instruments (apertures of 25 cm or larger) that have fainter light grasp do not necessarily confer an advantage in terms of viewing comets. The opportunity to view spectacular comets with relatively small aperture instruments in the 8 cm to 15 cm range is more frequent than might be guessed from the relatively rare attention they get in the mainstream press. In popular culture The depiction of comets in popular culture is firmly rooted in the long Western tradition of seeing comets as harbingers of doom and as omens of world-altering change. Halley's Comet alone has caused a slew of frightful or excited publications of all sorts at each of its reappearances. It was especially noted that the birth and death of some notable persons coincided with separate appearances of the comet, such as with writers Mark Twain (who correctly speculated that he'd "go out with the comet" in 1910) and Eudora Welty, to whose life Mary Chapin Carpenter dedicated the song Halley Came to Jackson. In science fiction, the impact of comets has been depicted as a threat overcome by technology and heroism (Deep Impact, 1998), or as a trigger of global apocalypse (Lucifer's Hammer, 1979) or of waves of zombies (Night of the Comet, 1984). Near impacts have been depicted in Jules Verne's Off on a Comet and Tove Jansson's Comet in Moominland, while a human expedition visits Halley's Comet in Arthur C. Clarke's 2061: Odyssey Three.

7,731 | Krav_Maga | Krav Maga (; , , lit. "contact combat" or "close combat") is an eclectic hand-to-hand combat system developed in Israel. It was derived from street-fighting skills developed by Imi Lichtenfeld, making use of his training as a boxer and wrestler, as a means of defending the Jewish quarter during a period of anti-Semitic activity in Bratislava in the mid- to late 1930s. In the late 1940's, following his emigration to Israel, he began to provide hand-to-hand combat training to what was to become the IDF, developing the techniques that became known as Krav Maga. It has since been refined for both civilian and military applications. Unlike most martial arts, Krav Maga is essentially a tactical defense skill. Its philosophy emphasizes threat neutralization, simultaneous defensive and offensive maneuvers, and aggressive endurance in a 'him-or-me' context. Krav Maga is still used by the Israel Defense Forces and several closely related variations have been developed and adopted by law enforcement, Mossad, FBI, United States special operations forces, Irish and British Special Forces. There are several organisations teaching variations of Krav Maga internationally. Etymology The name in Hebrew means "Hand-to-hand combat." Krav () meaning "combat" or "battle",and Maga () meaning "contact" or "touch". (Oxford Hebrew-English dictionary) Krav Maga teaches combat involving physical body contact as opposed to combat involving projectile or distance weaponry such as guns, artillery, tanks and planes. Basic principles Krav Maga is not a martial art by traditional standards. There are no rules for Krav Maga fighting, and no built-in distinctions in training between men and women. http://www.tkmc.com.au Tactical Krav Maga Self Defense It has no sporting federation, and there are no official uniforms or attire, although some organizations, internally, do recognize progress through training with rank badges and different levels. Techniques generally focus on training combatants in conditions approximating real-life scenarios. Krav Maga trains combatants for situations where losing would be potentially fatal. Its attack and defense maneuvers aim to neutralize the threat and facilitate rapid and safe escape. These include a variety of fast and fluid crippling attacks to vulnerable body parts through various efficient and often brutal strikes. The improvised use of any available aids is encouraged - maximizing personal safety in a fight is emphasized. Krav Maga training programs involve rapid learning, with offensive and defensive techniques introduced from the first lesson and retzev (pronounced ret-zef and meaning "continuous motion or momentum") playing an important part in both training and maneuvers. Israeli Krav Maga - FAQ Page While no limits are placed on techniques to be used in life-threatening situations, during training the legal need to minimize damage is generally stressed (at least in civilian contexts, and instructors are required to demonstrate how to moderate the techniques to suit the seriousness of the circumstances. Krav Maga basic training emphasizes the following: Do not get injured or injure training partners. Employ pre-emptive defensive techniques Change quickly from defensive into offensive techniques i.e. respond to an attack with overwhelming force, in the quickest time possible Use the most natural, quickest, reflexes of the body Exploit the opponent's vulnerabilities to their extreme Employ the aid of any available objects Krav Maga trainees learn to deal first with the immediate threat and then prevent further attacks, if necessary by neutralizing the attacker. Training is conducted in a methodical manner whilst taking account of the practitioners strengths and weaknesses Basic training Krav Maga has taken many techniques from other martial arts and included elements from Boxing, Muay Thai, Aikido, Judo, and Jujutsu. However, unlike the set routines and choreographed moves in martial arts, Krav Maga teaches realistic fighting and self-defense - attacks in social settings (pubs, clubs, street etc). Typical training often includes exercises simulating fighting against one or several opponents and/or whilst protecting another. This can also involve a debilitating scenario - the use of only one arm, while dizzy and against armed opponents. Basic training is a mixed aerobic and anaerobic workout, relying heavily on the use of protective pads. In striking this helps the trainee practice his maneuvers at full strength, whilst the holder experiences the impact they would feel when getting hit. Various personal guards are available which protect the person whist offering a realistic level of violence may be attained without risk of injury. Some schools incorporate "Strike and Fight," which consists of full-contact sparring intended to familiarize the student with the stresses of a violent situation. Training within extreme acoustic, visual, and verbal scenarios prepares students to ignore peripheral distractions and focus on the needs of the situation. Other training methods to increase realism might include blindfolding or exercising trainees to near exhaustion before dealing with a simulated attack as well as training outdoors on a variety of surfaces and restrictive situations. Training will also cover situational awareness in order to develop an understanding of one's surroundings and potentially threatening circumstances before an attack is launched. It may also cover "Self Protection": ways to deal with potentially violent situations, and physical and verbal methods to avoid violence whenever possible. Classes will feature a warm up to raise the heart rates, moving on to stretching. Various techniques are then shown which end in a retvez (fluid defense/attack). History Imi Lichtenfeld Krav Maga was developed in Hungary and Czechoslovakia in the 1930s by Imi Lichtenfeld, also known as Imi Sde-Or. (Sde-Or - "Light Field" - a calque of his surname into Hebrew) He first taught his fighting system in Bratislava in order to help protect the local Jewish community from Nazi militia. Upon arriving in the British Mandate of Palestine, Imi began teaching Kapap to the Haganah, the Jewish underground army. With the establishment of the State of Israel in 1948, Imi became the Chief Instructor of Physical Fitness and Krav Maga at the Israel Defense Forces (IDF) School of Combat Fitness. He served in the IDF for 15 years, during which time he continued to develop and refine his hand-to-hand combat method. History of Krav Maga In 1978, Imi founded the non-profit Israeli Krav Maga Association with several senior instructors. http://www.israelikrav.com He died in January 1998 in Netanya, Israel. International Krav Maga Federation Expansion to the USA Prior to 1980, all experts in Krav Maga lived in Israel and trained under the Israeli Krav Maga Association. That year marks the beginning of contact between Israeli Krav Maga experts and interested students in the United States. In 1981, a group of six Krav Maga instructors traveled to the US to demonstrate their system, primarily to local Jewish Community Centers. The New York Field Office of the FBI and the FBI's Main Training Center at Quantico, Virginia saw it and expressed interest. The result was a visit by 22 people from the US to Israel in the summer of 1981 to attend a basic Krav Maga instructor course. The graduates from this course returned to the US and began to establish training facilities in their local areas. Additional students traveled to Israel in 1984 and again in 1986 to become instructors. At the same time, instructors from Israel continued to visit the US. Law Enforcement training in the US began in 1985. International Krav Maga Federation Current usage All Israeli soldiers, including all Special Forces units such as the Sayeret Duvdevan, Duvdevan Training Documentation learn Krav Maga as part of their basic training. Former Special Forces Operator Still Trains Units Further, Krav Maga is the defensive tactics system used to train the Israeli Police, Police Training Documentation Israeli Intelligence and all Security Divisions. Israeli Presidential Security Staff Trains in Krav Maga - Article Bottom of Page Krav Maga is also taught to civilians, military, law enforcement and security agencies around the world. There have also been many spin-offs to Krav Maga, such as Tactical Krav Maga, founded by Itay Gil; Commando Krav Maga, founded by Moni Aizik; Special Forces Krav Maga, founded by Michal Cernohorsky; and Krav Maga Security, by Alain Cohen. The Swedish Army uses Krav Maga lightly in close combat training for urban warfare.

7,732 | Cheka | The sword-and-shield emblem of the Cheka-KGB. The Cheka (ЧК - чрезвычайная комиссия Chrezvychaynaya Komissiya, Extraordinary Commission ) was the first of a succession of Soviet state security organizations. It was created by a decree issued on December 20, 1917, by Vladimir Lenin and subsequently led by an aristocrat turned communist Felix Dzerzhinsky. After 1922, the Cheka underwent a series of reorganizations. From its founding, the Cheka was an important military and security arm of the Bolshevik communist government. In 1921 the Troops for the Internal Defense of the Republic (a branch of the Cheka) numbered 200,000. These troops policed labor camps, ran the Gulag system, conducted requisitions of food, liquidated political opponents (on both the right and the left), put down peasant rebellions, riots by workers, and mutinies in the Red Army, which was plagued by desertions. Nicolas Werth, Karel Bartošek, Jean-Louis Panné, Jean-Louis Margolin, Andrzej Paczkowski, Stéphane Courtois, The Black Book of Communism: Crimes, Terror, Repression, Harvard University Press, 1999, hardcover, 858 pages, ISBN 0-674-07608-7 Name The name of the agency was originally The All-Russian Extraordinary Commission for Combating Counter-Revolution and Sabotage (; Vserossijskaya Chrezvychajnaya Komissiya), but was often shortened to Cheka or VCheka. In 1918 its name was changed, becoming All-Russian Extraordinary Commission for Combating Counter-Revolution, Profiteering and Corruption. A member of Cheka was called a chekist. Chekists of the years after the -October Revolution wore leather jackets creating a fashion followed by Western communists; they are pictured in several films in this apparel. Despite changes over time, Soviet secret policemen were often referred to as "Chekists" throughout the Soviet period. In The Gulag Archipelago, Alexander Solzhenitsyn recalls that zeks in the labor camps used "old Chekist" as "a mark of special esteem" for particularly experienced camp administrators. The term is still found in use in Russia today (for example, President Vladimir Putin has been referred to in the Russian media as a "chekist" due to his career in the KGB). History The Cheka was created in December 1917, over a month after the October Revolution and the formation of the Bolshevik government. Its immediate precursor was the Extraordinary Commission to Fight Counter-revolution, established on , by the Milrevkom (the Military Revolutionary Committee of the Petrograd Soviet) on the proposal of Dzerzhinsky Carr (1958), p. 1. . Its members were the Bolsheviks Mykola Skrypnyk, Flerovski, Galkin, Valentin Trifonov Ibid. and presided by George Blagonravov Andrew Kalpaschnikoff, A prisoner of Trotsky's, 1920 . The Cheka was established on , by a decision of the Sovnarkom. It was subordinated to the Sovnarkom and its functions were, "to liquidate counter-revolution and sabotage, to hand over counter-revolutionaries and saboteurs to the revolutionary tribunals, and to apply such measures of repression as 'confiscation, deprivation of ration cards, publication of lists of enemies of the people etc.'" Ibid., p. 2. . The original members of the Vecheka were Peters, Ksenofontov, Averin, Ordzhonikidze, Peterson, Evseev, and Trifonov Ibid., p. 3. , but the next day Averin, Ordzhonikidze, and Trifonov were replaced by Fomin, Shchukin, Ilyin, and Chernov. A circular published on , gave the address of Vecheka's first headquarters as "Petrograd, Gorokhovaya 2, 4th floor". Originally, the members of the Cheka were exclusively Bolshevik; however, in January 1918, left SRs also joined the organization Schapiro (1984). The Left SRs were expelled or arrested later in 1918 following an attempted assassination against Lenin. In 1922, the Cheka was transformed into the State Political Administration or GPU, a section of the NKVD of the RSFSR. Operations Suppression of political opposition At the direction of Lenin, the Cheka performed mass arrests, imprisonments, and executions of "enemies of the people". In this, the Cheka said that they targeted "class enemies" such as the bourgeoisie, and members of the clergy; the first organized mass repression began against the libertarian Socialists of Petrograd in April 1918. However, within a month the Cheka had extended its repression to all political opponents of the communist government, including anarchists and others on the left. On May 1, 1918, a pitched battle took place in Moscow between the anarchists and the police. ( P.Avrich. G Maximoff) In response, the Cheka orchestrated a massive retaliatory campaign of repression, executions, and arrests against all opponents of the Bolshevik government that came to be known as Red Terror. The Red Terror, implemented by Dzerzhinsky on September 5, 1918, was vividly described by the Red Army journal Krasnaya Gazeta: In an attack on twenty-six anarchist political centres, forty anarchists were killed by Cheka forces, and 500 arrested and jailed. At the direction of Lenin and Trotsky, the Cheka and Red Army state security forces (later renamed the OGPU), shot, arrested, imprisoned, and executed thousands of persons, regardless of whether or not they had actually planned rebellion against the communist government. Most of the survivors were later deported to Siberian labor camps. An early Bolshevik Victor Serge described in his book Memoirs of a Revolutionary: The Cheka was also used against the armed anarchist Black Army of Nestor Makhno in Ukraine. After the Black Army had served its purpose in aiding the Red Army to stop the Whites under Denikin, the Soviet communist government decided it must eliminate the anarchist forces. In May 1919, two Cheka agents sent to assassinate Makhno were caught and executed. Avrich, Paul, Russian Anarchists and the Civil War, Russian Review, Volume 27, Issue 3 (July 1968), pp. 296-306 Persecution of deserters It is believed that more than 3 million deserters escaped from Red Army in 1919 and 1920. Around 500,000 deserters were arrested in 1919 and close to 800,000 in 1920 by troops of the dreaded 'Special Punitive Department' of the Cheka created to punish desertions Chamberlain, William Henry, The Russian Revolution: 1917-1921, New York: Macmillan Co. (1957), p. 131 . This force was used to forcefully repatriate deserters back into the Red Army, taking and shooting hostages to force compliance or to set an example. Throughout the course of the civil war, several thousand deserters were shot - a number comparable to that of belligerents during WWI. In September 1918, according to "The Black Book of Communism" in only twelve provinces of Russia, 48,735 deserters and 7,325 "bandits" were arrested, 1,826 were killed and 2,230 were executed. The exact identity of these individuals is confused by the fact that the Soviet Bolshevik government used the term 'bandit' to cover ordinary criminals as well as armed and unarmed political opponents, such as the anarchists. The Cheka later played a major role in the putting down the Kronstadt Rebellion by Soviet sailors in 1921. Number of victims Estimates on Cheka executions vary widely. The lowest figures are provided by Dzerzhinsky’s lieutenant Martyn Latsis, limited to RSFSR over the period 1918–1920: For the period 1918-July 1919, covering only twenty provinces of central Russia: 1918: 6,300; 1919 (up to July): 2,089; Total: 8,389 For the whole period 1918-19: 1918: 6,185; 1919: 3,456; Total: 9,641 For the whole period 1918-20: January-June 1918: 22; July-December 1918: more than 6,000; 1918-20: 12,733 Experts generally agree these semi-official figures are vastly understated. pages 463-464, Leggett (1986). W. H. Chamberlin, for example, claims “it is simply impossible to believe that the Cheka only put to death 12,733 people in all of Russia up to the end of the civil war.” pages 74-75, Chamberlin (1935). He provides the "reasonable and probably moderate" estimate of 50,000, while others provide estimates ranging up to 500,000. page 39, Rummel (1990). Statue plan stirs Russian row (BBC) Several scholars put the number of executions at about 250,000. page 28, Andrew and Mitrokhin, The Sword and the Shield, paperback edition, Basic books, 1999. page 180, Overy, The Dictators: Hitler's Germany, Stalin's Russia, W. W. Norton & Company; 1st American Ed edition, 2004. One difficulty is that the Cheka sometimes recorded the deaths of executed anarchists and other political dissidents as criminals, 'armed bandits', or 'armed gangsters'. Some believe it is possible more people were murdered by the Cheka than died in battle. page 649, Figes (1996). Lenin himself seemed unfazed by the killings. On 12 January 1920, while addressing trade union leaders, he said: "We did not hesitate to shoot thousands of people, and we shall not hesitate, and we shall save the country." pages 72 & 73, Volkogonov (1998). On 14 May 1921, the Politburo, chaired by Lenin, passed a motion "broadening the rights of the [Cheka] in relation to the use of the [death penalty]." page 238, Volkogonov (1994). Atrocities The Cheka is reported to have practiced torture. Victims were reportedly skinned alive, scalped, "crowned" with barbed wire, impaled, crucified, hanged, stoned to death, tied to planks and pushed slowly into furnaces or tanks of boiling water, and rolled around naked in internally nail-studded barrels. Chekists reportedly poured water on naked prisoners in the winter-bound streets until they became living ice statues. Others reportedly beheaded their victims by twisting their necks until their heads could be torn off. The Chinese Cheka detachments stationed in Kiev reportedly would attach an iron tube to the torso of a bound victim and insert a rat into the other end which was then closed off with wire netting. The tube was then held over a flame until the rat began gnawing through the victim's guts in an effort to escape. Anton Denikin's investigation discovered corpses whose lungs, throats, and mouths had been packed with earth. pages 177-179, Melg(o)unov (1925). pages 383-385, Lincoln (1999). page 646, Figes (1996). Women and children were also victims of Cheka terror. Women would sometimes be tortured and raped before being shot. Children between the ages of 8 and 16 were imprisoned and occasionally executed. page 198, Leggett (1986). In popular culture The Cheka were popular staples in Soviet film and literature. This was partly due to a romanticization of the organisation in the post-Stalin period, and also because they provided a useful action/detection template. Films featuring the Cheka include Osterns Miles of Fire, Nikita Mikhalkov's At Home among Strangers, the miniseries The Adjutant of His Excellency, and also Dead Season starring Donatas Banionis and the 1992 Soviet Union film Chekist. Chekist (1992) In Spain, during the Spanish Civil War, the detention and torture centers operated by the Communists were named checas after the Soviet organization.

7,733 | Cameroon | The Republic of Cameroon () is a unitary republic of central and western Africa. It is bordered by Nigeria to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Cameroon's coastline lies on the Bight of Bonny, part of the Gulf of Guinea and the Atlantic Ocean. The country is called "Africa in miniature" for its geological and cultural diversity. Natural features include beaches, deserts, mountains, rainforests, and savannas. The highest point is Mount Cameroon in the southwest, and the largest cities are Douala, Yaoundé, and Garoua. Cameroon is home to over 200 different ethnic and linguistic groups. The country is well known for its native styles of music, particularly makossa and bikutsi, and for its successful national football team. English and French are the official languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area Rio dos Camarões ("River of Prawns"), the name from which Cameroon derives. Fulani soldiers founded the Adamawa Emirate in the north in the 19th century, and various ethnic groups of the west and northwest established powerful chiefdoms and fondoms. Cameroon became a German colony in 1884. After World War I, the territory was divided between France and Britain as League of Nations mandates. The Union des Populations du Cameroun political party advocated independence but was outlawed in the 1950s. It waged war on French and Cameroonian forces until 1971. In 1960, French Cameroun became independent as the Republic of Cameroun under President Ahmadou Ahidjo. The southern part of British Cameroons merged with it in 1961 to form the Federal Republic of Cameroon. The country was renamed the United Republic of Cameroon in 1972 and the Republic of Cameroon in 1984. Compared to other African countries, Cameroon enjoys relatively high political and social stability. This has permitted the development of agriculture, roads, railways, and large petroleum and timber industries. Nevertheless, large numbers of Cameroonians live in poverty as subsistence farmers. Power lies firmly in the hands of the president, Paul Biya, and his Cameroon People's Democratic Movement party, and corruption is widespread. The Anglophone community has grown increasingly alienated from the government, and Anglophone politicians have called for greater decentralisation and even the secession of the former British-governed territories. History The territory of present day Cameroon was first settled during the Neolithic. The longest continuous inhabitants are groups such as the Baka. DeLancey and DeLancey 2. The Sao culture arose around Lake Chad c. AD 500 and gave way to the Kanem and its successor state, the Bornu empire. Kingdoms, fondoms, and chiefdoms arose in the west. European sailors reached the coast in 1472. They noted an abundance of prawns and crayfish in the Wouri River and named it , Portuguese for "River of Prawns", and the phrase from which Cameroon is derived. Over the following few centuries, European interests regularised trade with the coastal peoples, and Christian missionaries pushed inland. In the early 19th century, Modibo Adama led Fulani soldiers on a jihad in the north against non-Muslim and partially Muslim peoples and established the Adamawa Emirate. Settled peoples who fled the Fulani caused a major redistribution of population. Fanso 84. The German Empire claimed the territory as the colony of Kamerun in 1884 and began a steady push inland. They initiated projects to improve the colony's infrastructure, relying on a harsh system of forced labour. DeLancey and DeLancey 125. World War I reached Cameroon on 25 August at Tepe. Garua was unsuccessfully attacked by the British on 29-30 and on the sea an Allied Expeditionary Force under General Dobell captured Duala on 27 September 1914. The Cameroons campaigns lasted up to February 1916. Ekoko 454. With the defeat of Germany in World War I, Kamerun became a League of Nations mandate territory and was split into French and British Cameroons in 1919. The French carefully integrated the economy of Cameroun with that of France DeLancey and DeLancey 5. and improved the infrastructure with capital investments, skilled workers, and continued forced labour. The British administered their territory from neighbouring Nigeria. Natives complained that this made them a neglected "colony of a colony". Nigerian migrant workers flocked to Southern Cameroons, ending forced labour but angering indigenous peoples. DeLancey and DeLancey 4. The League of Nations mandates were converted into United Nations Trusteeships in 1946, and the question of independence became a pressing issue in French Cameroun. France outlawed the most radical political party, the Union des Populations du Cameroun (UPC), on 13 July 1955. This prompted a long guerrilla war and the assassination of the party's leader, Ruben Um Nyobé. DeLancey and DeLancey 6. In British Cameroons, the question was whether to reunify with French Cameroun or join Nigeria. In May 1957 André-Marie Mbida became Cameroon's first Prime Minister. On 1 January 1960, French Cameroun gained independence from France under President Ahmadou Ahidjo, and on 1 October 1961, the formerly British Southern Cameroons united with its neighbour to form the Federal Republic of Cameroon. Ahidjo used the ongoing war with the UPC and fears of ethnic conflict to concentrate power in the presidency, continuing with this even after the suppression of the UPC in 1971. His political party, the Cameroon National Union (CNU), became the sole legal political party on 1 September 1966 and in 1972, the federal system of government was abolished in favour of a United Republic of Cameroon, headed from Yaoundé. DeLancey and DeLancey 19. Ahidjo pursued an economic policy of planned liberalism, prioritising cash crops and petroleum exploitation. The government used oil money to create a national cash reserve, pay farmers, and finance major development projects; however, many initiatives failed when Ahidjo appointed unqualified allies to direct them. DeLancey and DeLancey 7. Ahidjo stepped down on 4 November 1982 and left power to his constitutional successor, Perrin Fokou. However, Ahidjo remained in control of the CNU and tried to run the country from behind the scenes until Fokou and his allies pressured him into resigning. Fokou began his administration by moving toward a more democratic government, but a failed coup d'état nudged him toward the leadership style of his predecessor. DeLancey and DeLancey 8. An economic crisis took effect in the mid-1980s to late 1990s as a result of international economic conditions, drought, falling petroleum prices, and years of corruption, mismanagement, and cronyism. Cameroon turned to foreign aid, cut government spending, and privatised industries. With the reintroduction of multi-party politics in December 1990, Anglophone pressure groups called for greater autonomy, with some advocating complete secession as the Republic of Ambazonia. DeLancey and DeLancey 9. In February 2008, Cameroon experienced its worse violence in 15 years when a transport union strike in Douala escalated into violent protests in 31 municipal areas. Nkemngu. Matthews. Politics and government The President of Cameroon has broad, unilateral powers to create policy, administer government agencies, command the armed forces, negotiate and ratify treaties, and declare a state of emergency. "Background Notes: Cameroon; Neba 250. The president appoints government officials at all levels, from the prime minister (considered the official head of government), to the provincial governors, divisional officers, and urban-council members in large cities. The president is selected by popular vote every seven years. In smaller municipalities, the public elects mayors and councilors. Corruption is rife at all levels of government. In 1997, Cameroon established anti-corruption bureaus in 29 ministries, but only 25% became operational, IRIN, "New anti-corruption drive". and in 2007, Transparency International placed Cameroon at number 138 on a list of 163 countries ranked from least to most corrupt. "Corruption Perceptions Index". On 18 January 2006, Biya initiated an anti-corruption drive under the direction of the National Anti-Corruption Observatory. Cameroon's legal system is largely based on French civil law with common law influences. "Cameroon", The World Factbook. Although nominally independent, the judiciary falls under the authority of the executive's Ministry of Justice. "Background Note: Cameroon". The president appoints judges at all levels. The judiciary is officially divided into tribunals, the court of appeal, and the supreme court. The National Assembly elects the members of a nine-member High Court of Justice that judges high-ranking members of government in the event they are charged with high treason or harming national security. Human rights organisations accuse police and military forces of mistreating and even torturing criminal suspects, ethnic minorities, homosexuals, and political activists. "Cameroon", Amnesty International; "Cameroon (2006)", Freedom House; "Cameroon", Country Reports on Human Rights Practices, U.S. Department of State; "Elections to the Human Rights Council", Amnesty International. Prisons are overcrowded with little access to adequate food and medical facilities, "Elections to the Human Rights Council". and prisons run by traditional rulers in the north are charged with holding political opponents at the behest of the government. "Cameroon (2006)", Freedom House. However, since the early 2000s, an increasing number of police and gendarmes have been prosecuted for improper conduct. The National Assembly makes legislation. The body consists of 180 members who are elected for five-year terms and meet three times per year. Laws are passed on a majority vote. Rarely has the assembly changed or blocked legislation proposed by the president. The 1996 constitution establishes a second house of parliament, the 100-seat Senate, but this body has never been put into practice. The government recognises the authority of traditional chiefs, fons, and lamibe to govern at the local level and to resolve disputes as long as such rulings do not conflict with national law. "Background Note: Cameroon"; Neba 252. President Perrin Fokou's Cameroon People's Democratic Movement (CPDM) was the only legal political party until December 1990. Numerous ethnic and regional political groups have since formed. The primary opposition is the Social Democratic Front (SDF), based largely in the Anglophone region of the country and headed by John Fru Ndi. West 11. Biya and his party have maintained control of the presidency and the National Assembly in national elections, but rivals contend that these have been unfair. Human rights organisations allege that the government suppresses the freedoms of opposition groups by preventing demonstrations, disrupting meetings, and arresting opposition leaders and journalists. "Cameroon", Amnesty International. Freedom House ranks Cameroon as "not free" in terms of political rights and civil liberties. Cameroon is ranked a six in both categories on a scale of one to seven, with one being "most free" and seven being "least free". "Cameroon (2006)", Freedom House. The last parliamentary elections were held on 22 July 2007. Kandemeh. Cameroon is a member of both the Commonwealth of Nations and La Francophonie. Its foreign policy closely follows that of its main ally, France. DeLancey and DeLancey 126; Ngoh 328. The country relies heavily on France for its defence, although military spending is high in comparison to other sectors of government. DeLancey and DeLancey 30. Biya has clashed with the government of Nigeria over possession of the Bakassi peninsula and with Gabon's president, El Hadj Omar Bongo, over personal rivalries. Nevertheless, civil war presents a more credible threat to national security, as tensions between Christians and Muslims and between Anglophones and Francophones remain high. MacDonald 69. Education and health Most children have access to free, state-run schools or subsidised, private and religious facilities. Mbaku 15. The educational system is a mixture of British and French precedents DeLancey and DeLancey 105–6. with most instruction in English or French. Mbaku 16. Cameroon has one of the highest school attendance rates in Africa. Girls attend school less regularly than boys do because of cultural attitudes, domestic duties, early marriage and pregnancy, and sexual harassment. Although attendance rates are higher in the south, a disproportionate number of teachers are stationed there, leaving northern schools chronically understaffed. Seven state-run universities serve Cameroon's student population. More than 60,000 students were enrolled for the 1998–1999 school year. A council of deans, school directors, and representatives of state ministries governs the schools under the leadership of a vice-chancellor. State funding for universities is low, and student registrations nominally make up 25% of the higher education budget. Since 1993, with the decentralisation of university education, free tuition was replaced with registration fees of 50,000FCFA for Cameroonian nationals and 200,000FCFA for foreign nationals. Although there was initial resistance to this new format, the government has been vindicated almost two decades later, as university attendance has since more than quadruppled. Competitiveness between the various universities has been encouraged. Administratively, the University of Buea, dubbed the Anglo-Saxon university, is the best organized. However, cuts in faculty salaries in 1993 have made it difficult to maintain full staff, as there has been an increasing exodus of teachers to foreign countries in search of better wages. Njeuma. Since 1990, private institutions have sprung up in at least five regions. These schools charge fees that are five to ten times those levied by state schools. Nevertheless, they offer short professional-training programmes in areas such as accounting, management, journalism, and Internet technologies, so they are popular with students. Some of these schools nonetheless fall short of government minimum standards of infrastructure and faculty and must operate unlicensed. The quality of health care is generally low. DeLancey and DeLancey 21. Outside the major cities, facilities are often dirty and poorly equipped. West 64. Endemic diseases include dengue fever, filariasis, leishmaniasis, malaria, meningitis, schistosomiasis, and sleeping sickness. West 58–60. The HIV/AIDS seroprevalence rate is estimated at 5.4% for those aged 15–49, "Cameroon", UNAIDS. although a strong stigma against the illness keeps the number of reported cases artificially low. Traditional healers remain a popular alternative to Western medicine. Lantum and Monono 14. Regions and divisions The constitution divides Cameroon into 10 semi-autonomous regions, each under the administration of an elected Regional Council. Although provided for by the 1996 constitution,it was not until the 12th of November 2008 that the incumbent president, Paul Biya signed a decree replacing provinces with regions.Each region is headed by a presidentially appointed governor. These leaders are charged with implementing the will of the president, reporting on the general mood and conditions of the regions, administering the civil service, keeping the peace, and overseeing the heads of the smaller administrative units. Governors have broad powers: they may order propaganda in their area and call in the army, gendarmes, and police. Neba 250. The provinces are subdivided into 58 divisions (French ). These are headed by presidentially appointed divisional officers (), who perform the governors' duties on a smaller scale. The divisions are further sub-divided into sub-divisions (), headed by assistant divisional officers (). The districts, administered by district heads (), are the smallest administrative units. These are found in large sub-divisions and in regions that are difficult to reach. The three northernmost provinces are the Far North (), North (), and Adamawa (). Directly south of them are the Centre () and East (). The South Province () lies on the Gulf of Guinea and the southern border. Cameroon's western region is split into four smaller provinces: The Littoral () and Southwest () provinces are on the coast, and the Northwest () and West () provinces are in the western grassfields. The Northwest and Southwest were once part of British Cameroons; the other provinces were in French Cameroun. Geography and climate At , Cameroon is the world's 53rd-largest country. Demographic Yearbook 1. It is comparable in size to Papua New Guinea and somewhat larger than the U.S. state of California. "Rank Order - Area". The country is located in Central and West Africa on the Bight of Bonny, part of the Gulf of Guinea and the Atlantic Ocean. Tourist literature describes Cameroon as "Africa in miniature" because it exhibits all major climates and vegetation of the continent: coast, desert, mountains, rainforest, and savanna. DeLancey and DeLancey 16. The country's neighbours are Nigeria to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Cameroon is divided into five major geographic zones distinguished by dominant physical, climatic, and vegetative features. The coastal plain extends 15 to 150 kilometres (10 to 90 mi) inland from the Gulf of Guinea Fomesky et al. 6. and has an average elevation of 90 metres (295 ft). Neba 14. Exceedingly hot and humid with a short dry season, this belt is densely forested and includes some of the wettest places on earth. Neba 28. "Highest Average Annual Precipitation Extremes". The South Cameroon Plateau rises from the coastal plain to an average elevation of 650 metres (2,130 ft). Neba 16. Equatorial rainforest dominates this region, although its alternation between wet and dry seasons makes it is less humid than the coast. An irregular chain of mountains, hills, and plateaus known as the Cameroon range extends from Mount Cameroon on the coast—Cameroon's highest point at 4,095 metres (13,435 ft)—almost to Lake Chad at Cameroon's northern tip. This region has a mild climate, particularly on the Western High Plateau, although rainfall is high. Its soils are among Cameroon's most fertile, especially around volcanic Mount Cameroon. Neba 17. Volcanism here has created crater lakes. On 21 August 1986, one of these, Lake Nyos, belched carbon dioxide and killed between 1,700 and 2,000 people. DeLancey and DeLancey 161 report 1,700 killed; Hudgens and Trillo 1054 say "at least 2,000"; West 10 says "more than 2,000". The southern plateau rises northward to the grassy, rugged Adamawa Plateau. This feature stretches from the western mountain area and forms a barrier between the country's north and south. Its average elevation is 1,100 metres (3,600 ft), and its temperature ranges from 22 to 25 °C (72 to 77 °F) with high rainfall. Gwanfogbe et al. 20; Neba 29. The northern lowland region extends from the edge of the Adamawa to Lake Chad with an average elevation of 300 to 350 metres (980 to 1,150 ft). Its characteristic vegetation is savanna scrub and grass. This is an arid region with sparse rainfall and high median temperatures. Cameroon has four patterns of drainage. In the south, the principal rivers are the Ntem, Nyong, Sanaga, and Wouri. These flow southwestward or westward directly into the Gulf of Guinea. The Dja and Kadéï drain southeastward into the Congo River. In northern Cameroon, the Bénoué River runs north and west and empties into the Niger. The Logone flows northward into Lake Chad, which Cameroon shares with three neighbouring countries. Economy and infrastructure Cameroon's per-capita GDP (PPP) was estimated as US $2,421 in 2005, "World Economic and Financial Surveys". one of the ten highest in sub-Saharan Africa. Musa, "Biya plan to keep power in Cameroon clears hurdle". Major export markets include France, Italy, South Korea, Spain, and the United Kingdom. Cameroon is part of the Bank of Central African States (of which it is the dominant economy), the Customs and Economic Union of Central Africa (UDEAC) and the Organization for the Harmonization of Business Law in Africa (OHADA). Its currency is the CFA franc. Red tape, high taxes, and endemic corruption have impeded growth of the private sector. Neba 132. Unemployment was estimated at 30% in 2001, and about 48% of the population was living below the poverty threshold in 2000. Since the late 1980s, Cameroon has been following programmes advocated by the World Bank and International Monetary Fund (IMF) to reduce poverty, privatise industries, and increase economic growth. Tourism is a growing sector, particularly in the coastal area, around Mount Cameroon, and in the north. Neba 173–6. Cameroon's natural resources are better suited to agriculture and forestry than to industry. An estimated 70% of the population farms, and agriculture comprised an estimated 45.2% of GDP in 2006. Most agriculture is done at the subsistence scale by local farmers using simple tools. They sell their surplus produce, and some maintain separate fields for commercial use. Urban centres are particularly reliant on peasant agriculture for their foodstuffs. Neba 208. Soils and climate on the coast encourage extensive commercial cultivation of bananas, cocoa, oil palms, rubber, and tea. Inland on the South Cameroon Plateau, cash crops include coffee, sugar, and tobacco. Coffee is a major cash crop in the western highlands, and in the north, natural conditions favour crops such as cotton, groundnuts, and rice. Reliance on agricultural exports makes Cameroon vulnerable to shifts in their prices. Livestock are raised throughout the country. Fishing employs some 5,000 people and provides 20,000 tons of seafood each year. Neba 185. Bushmeat, long a staple food for rural Cameroonians, is today a delicacy in the country's urban centres. The commercial bushmeat trade has now surpassed deforestation as the main threat to wildlife in Cameroon. West 24. The southern rainforest has vast timber reserves, estimated to cover 37% of Cameroon's total land area. Neba 189. However, large areas of the forest are difficult to reach. Logging, largely handled by foreign-owned firms, provides the government US$60 million a year, and laws mandate the safe and sustainable exploitation of timber. Nevertheless, in practice, the industry is one of the least regulated in Cameroon. Neba 195. West 23. Factory-based industry accounted for an estimated 16.1% of GDP in 2006. More than 75% of Cameroon's industrial strength is located in Douala and Bonabéri. Neba 170. Cameroon possesses substantial mineral resources, but these are not extensively mined. Petroleum exploitation has fallen since 1985, but this is still a substantial sector such that dips in prices have a strong effect on the economy. Neba 158. Rapids and waterfalls obstruct the southern rivers, but these sites offer opportunities for hydroelectric development and supply most of Cameroon's energy. West 12. The Sanaga River powers the largest hydroelectric station, located at Edéa. Neba 160. The rest of Cameroon's energy comes from oil-powered thermal engines. Much of the country remains without reliable power supplies. Neba 161. Transport in Cameroon is often difficult. Roads are poorly maintained Neba 199. and subject to inclement weather, since only 10% of the roadways are tarred. Roadblocks often serve little other purpose than to allow police and gendarmes to collect bribes from travellers. Hudgens and Trillo 1036. Road banditry has long hampered transport along the eastern and western borders, and since 2005, the problem has intensified in the east as the Central African Republic has further destabilised. Musa, "Gunmen kill one, kidnap 22 in Cameroon near CAR". Rail service runs from Kumba in the west to Bélabo in the east and north to Ngaoundéré. International airports are located in Douala and Garoua with a smaller facility at Yaoundé. The Wouri River estuary provides a harbour for Douala, the country's principal seaport. In the north, the Bénoué River is seasonally navigable from Garoua across into Nigeria. Although press freedoms have improved since the early 2000s, the press is corrupt and beholden to special interests and political groups. "Cameroon - Annual Report 2007". Newspapers routinely self-censor to avoid government reprisals. "Cameroon", Country Reports on Human Rights Practices. The major radio and television stations are state-run, Neba 207. and other communications, such as land-based telephones and telegraphs, are largely under government control. Mbaku 20. However, cell phone networks and Internet providers have increased dramatically since the early 2000s Mbaku 20–1. and are largely unregulated. Religion The Christian community, makes up 40 percent of the population. There is also 40 percent of the population who maintain Indigenous beliefs, and Islam is practiced by 20 percent of the country's population. the World Factbook CIA the World Factbook Christians are concentrated chiefly in the southern and western provinces and Muslims reside in large numbers in every province. There is significant internal migration. Large cities have significant populations of both groups, with mosques and churches often located near each other. The two Anglophone provinces of the western region largely are Protestant and the francophone provinces of the southern and western regions are largely Catholic. In the northern provinces, the locally dominant Fulani (or Peuhl) ethnic group is mostly Muslim, but the overall population is fairly evenly mixed between Muslims, Christians, and animists, each often living in its own community. The Bamoun ethnic group of the West Province is largely Muslim. Traditional indigenous religious beliefs are practiced in rural areas throughout the country but rarely are practiced publicly in cities, in part because many indigenous religious groups are intrinsically local in character. U.S.Department of State Demographics 2005 estimates place Cameroon's population at 17,795,000. World Population Prospects. This population is young: an estimated 41.2% are under 15, and 96.7% are under 65. The birth rate is estimated at 33.89 births per 1,000 people, the death rate at 13.47. "Cameroon". World Factbook. The life expectancy is 51.16 years (50.98 years for males and 51.34 years for females). Cameroon's population is almost evenly divided between urban and rural dwellers. West 3. Population density is highest in the large urban centres, the western highlands, and the northeastern plain. Neba 109–11. Douala, Yaoundé, and Garoua are the largest cities. In contrast, the Adamawa Plateau, southeastern Bénoué depression, and most of the South Cameroon Plateau are sparsely populated. Neba 111. People from the overpopulated western highlands and the underdeveloped north are moving to the coastal plantation zone and urban centres for employment. Neba 105–6. Smaller movements are occurring as workers seek employment in lumber mills and plantations in the south and east. Neba 106. Although the national sex ratio is relatively even, these out-migrants are primarily males, which leads to unbalanced ratios in some regions. Neba 103–4. Both monogamous and polygamous marriage are practiced, and the average Cameroonian family is large and extended. Mbaku 139. In the north, women tend to the home, and men herd cattle or work as farmers. In the south, women grow the family's food, and men provide meat and grow cash crops. Cameroonian society is male-dominated, and violence and discrimination against women is common. Mbaku 141. At the onset of puberty, an estimated 26% of girls are subjected to breast ironing, a practice by which their breasts are pounded or massaged with heated objects to prevent them from developing. The goal is to prevent the girls from becoming precociously sexually active and to protect them from sexual assault. Sa'ah. Female genital mutilation is practiced in portions of the Far North and Southwest provinces. Estimates identify anywhere from 230 to 282 different ethnic and linguistic groups in Cameroon. Neba 65, 67. West 13. The Adamawa Plateau broadly bisects these into northern and southern divisions. The northern peoples are Sudanese ethnic groups, who live in the central highlands and the northern lowlands, and the Fulani, who are spread throughout northern Cameroon. A small number of Shuwa Arabs live near Lake Chad. Southern Cameroon is inhabited by speakers of Bantu and Semi-Bantu languages. Bantu-speaking groups inhabit the coastal and equatorial zones, while speakers of Semi-Bantu languages live in the Western grassfields. Some 5,000 Pygmies roam the southeastern and coastal rainforests or live in small, roadside settlements. Neba 48. Nigerians, especially Igbo, make up the largest group of foreign nationals. Neba 108. In 2007, Cameroon hosted a total population of refugees and asylum seekers of approximately 97,400. Of these, 49,300 were from the Central African Republic (many driven west by war), International Federation of Red Cross and Red Crescent Societies. 41,600 from Chad, and 2,900 from Nigeria. Kidnappings of Cameroonian citizens by Central African bandits have increased since 2005. Cameroon has a high level of religious freedom and diversity. The northern peoples are predominantly Muslim, although some ethnic groups retain native animist beliefs and are called Kirdi ("pagan") by the Fulani. The U.S. Department of State claims that some Muslims discriminate against Christians and followers of traditional beliefs in the north. Southern ethnic groups predominantly follow Christian or animist beliefs, or a syncretic combination of the two. People widely believe in witchcraft, and the government outlaws such practices. Geschiere 169–70. Suspected witches are often subject to mob violence. The European languages introduced during colonialism have created a linguistic divide between the English-speaking fifth of the population who live in the Northwest and Southwest provinces and the French-speaking remainder of the country. DeLancey and DeLancey 28. Both English and French are official languages. Cameroonian Pidgin English is the most common lingua franca, especially in the formerly British-administered territories. Neba 94. A mixture of English, French, and Pidgin called Camfranglais has been gaining popularity in urban centres since the mid-1970s. DeLancey and DeLancey 131; Niba. The civil society plays a great role as concerns the economy of Cameroon. An example is the Youth Employment Fund, a not-for-profit non-governmental organisation assisting the government to fight against youth unemployment. Culture + Holidays Date English Name 1 January New Year's Day 11 February National Youth Day 1 May Labour Day 20 May National Day 15 August Assumption 1 October Unification Day 25 December Christmas Each of Cameroon's ethnic groups has its own unique cultural forms. Typical celebrations include births, deaths, plantings, harvests, and religious rituals. Seven national holidays are observed throughout the year, and movable holidays include the Christian holy days of Good Friday, Easter Sunday, Easter Monday, and Ascension; and the Muslim holy days of 'Id al-Fitr, 'Id al-Adha, and Eid Miladun Nabi. Music and dance are an integral part of Cameroonian ceremonies, festivals, social gatherings, and storytelling. Mbaku 189; West 18. Traditional dances are highly choreographed and separate men and women or forbid participation by one sex altogether. Mbaku 204. The goals of dances range from pure entertainment to religious devotion. West 18. Traditionally, music is transmitted orally. In a typical performance, a chorus of singers echoes a soloist. Mbaku 189. Musical accompaniment may be as simple as clapping hands and stomping feet, Mbaku 191. but traditional instruments include bells worn by dancers, clappers, drums and talking drums, flutes, horns, rattles, scrapers, stringed instruments, whistles, and xylophones; the exact combination varies with ethnic group and region. Some performers sing complete songs by themselves, accompanied by a harplike instrument. West 18–9. Cameroon also has a definite culture rooted in language. Today, English speakers from Cameroon are known for a distinctive accent and signature rolling of r's as a French lingual flourish. Popular music styles include ambasse bey of the coast, assiko of the Bassa, mangambeu of the Bangangte, and tsamassi of the Bamileke. DeLancey and DeLancey 184. Nigerian music has influenced Anglophone Cameroonian performers, and Prince Nico Mbarga's highlife hit "Sweet Mother" is the top-selling African record in history. Mbaku 200. The two most popular styles are makossa and bikutsi. Makossa developed in Douala and mixes folk music, highlife, soul, and Congo music. Performers such as Manu Dibango, Francis Bebey, Moni Bilé, and Petit-Pays popularised the style worldwide in the 1970s and 1980s. Bikutsi originated as war music among the Ewondo. Artists such as Anne-Marie Nzié developed it into a popular dance music beginning in the 1940s, and performers such as Mama Ohandja and Les Têtes Brulées popularised it internationally during the 1960s, 1970s, and 1980s. DeLancey and DeLancey 51; Nkolo & Ewens 443. Cuisine varies by region, but a large, one-course, evening meal is common throughout the country. A typical dish is based on cocoyams, maize, manioc, millet, plantains, potatoes, rice, or yams, often pounded into dough-like fufu (cous-cous). This is served with a sauce, soup, or stew made from greens, groundnuts, palm oil, or other ingredients. West 84–5. Meat and fish are popular but expensive additions. Mbaku 121–2. Dishes are often quite hot, spiced with salt, red pepper, and Maggi. In more affluent areas of Cameroon a more French style cuisine is eaten. Traditional arts and crafts are practiced throughout the country for commercial, decorative, and religious purposes. Woodcarvings and sculptures are especially common. West 17. The high-quality clay of the western highlands is suitable for pottery and ceramics. Other crafts include basket weaving, beadworking, brass and bronze working, calabash carving and painting, embroidery, and leather working. Traditional housing styles make use of locally available materials and vary from temporary wood-and-leaf shelters of nomadic Mbororo to the rectangular mud-and-thatch homes of southern peoples. Dwellings made from materials such as cement and tin are increasingly common. Mbaku 110–3. Cameroonian literature and film have concentrated on both European and African themes. Colonial-era writers such as Louis-Marie Pouka and Sankie Maimo were educated by European missionary societies and advocated assimilation into European culture as the means to bring Cameroon into the modern world. Mbaku 80–1 After World War II, writers such as Mongo Beti and Ferdinand Oyono analysed and criticised colonialism and rejected assimilation. Fitzpatrick 38; Mbaku 77, 83–4; Volet. Shortly after independence, filmmakers such as Jean-Paul Ngassa and Thérèse Sita-Bella explored similar themes. DeLancey and DeLancey 119–20; West 20. In the 1960s, Mongo Beti and other writers explored post-colonialism, problems of African development, and the recovery of African identity. Mbaku 85–6. Meanwhile, in the mid-1970s, filmmakers such as Jean-Pierre Dikongué Pipa and Daniel Kamwa dealt with the conflicts between traditional and post-colonial society. Literature and films during the next two decades concentrated more on wholly Cameroonian themes. DeLancey and DeLancey 120. National policy strongly advocates sport in all forms. Traditional sports include canoe racing and wrestling, and several hundred runners participate in the 40 km (24.8 mi) Mount Cameroon Race of Hope each year. West 127. Cameroon is one of the few tropical countries to have competed in the Winter Olympics. However, sport in Cameroon is dominated by association football (soccer). Amateur football clubs abound, organised along ethnic lines or under corporate sponsors. The Cameroon national football team has been one of the most successful in the world since its strong showing in the 1990 FIFA World Cup. Cameroon has won four African Cup of Nations titles and the gold medal at the 2000 Olympics. West 92–3, 127.

7,735 | Athena | In Greek mythology, Athena (also called Athene, Attic: , Athēnâ or , Athēnaía, Epic: , Athēnaíē, Ionic: , Athḗnē, Doric: , Athána; ) is the shrewd companion of heroes and the goddess of heroic endeavour. She is the virgin patron of Athens, which built the Parthenon to worship her. Overview Athena's worship dates back to early times as the patron of Athens. Her persona persisted so much that many myths about her changed to adapt to cultural changes over the Ancient Greek eras. The Greek philosopher, Plato (429–347 BC), identified her with the Libyan deity, Neith, the war-goddess and huntress deity of the Egyptians since the ancient predynastic period, also identified with weaving. Athena became the goddess of wisdom as philosophy became a part of the cult in the later fifth century and Classical Greece. Walter Burkert, Greek Religion 1985:VII "Philosophical Religion" treats these transformations. She was the patroness of weaving and other crafts (Athena Ergane), and led battles as the disciplined side of (Athena Promachos). Violence and bloodlust were Ares' domain. The metalwork of weapons fell under her patronage. Athena's wisdom includes the cunning intelligence (metis) of such figures as Odysseus. She appears attended by an owl, often accompanied by the goddess of victory, Nike, whom in established icons she offers upon her extended hand. Athena wears a breastplate of either goatskin or snake skin called the Aegis, which later myths say her father, Zeus, gave to her, Zeus is also "Aegis-bearing Zeus". although in other older cultural contexts she already carries this association. Visually, she often appears helmeted and with a shield bearing the Gorgon head, the hallmark of the early goddess cult in Greece and positioned highest in the apex of the front facade of the Parthenon. Later sources say Perseus gave her the shield as a votive gift. A serpent often accompanies this goddess at the base of the staff of her lance. The sea, ships, horses, and chariots associate with her, but with less frequency. The image to the right shows a winged lioness on her helmet, an image associated with warrior deities in many early cultures, including Egypt. Athena, an armed warrior goddess, appears in Greek mythology as a helper of many heroes, including Odysseus, Jason, and Heracles. In Classical Greek myths she never consorts with a lover, earning the title Athena Parthenos ("Athena the virgin"), hence the name of her most famous temple, the Parthenon, on the Acropolis in Athens. A remnant of archaic myth depicts her as the adoptive mother of Erechtheus/Erichthonius by the foiled rape by Hephaestus. Pseudo-Apollodorus, Bibliotheke 3.14.6. Other variants relate that the serpent who accompanied Athena, also called Erichthonius, was born to Gaia, Earth when the rape failed and the semen landed on Gaia, impregnating her. After the birth, Gaia gave him to Athena. In her role as a protector of the city, many people throughout the Greek world worshiped Athena as Athena Polias ("Athena of the city"). Athens and Athena bear etymologically connected names. "Whether the goddess was named after the city or the city after the goddess is an ancient dispute" (Burkert 1985:139). Mythology Birth Image from the temple of Athena at Mycenae, c. 625 BC (National Archaeological Museum of Athens) In The Greek Myths (8.a, ff.), Robert Graves notes early myths about the birth of Athena which describe her as a goddess from Libya, whose worship came to the Greeks from Crete after arriving there as early as 4,000 BC. According to Graves, Hesiod (c. 700 BC) relates that Athena was a parthenogenous daughter of Metis, wisdom or knowledge, a Titan who ruled the fourth day and the planet Mercury. Other variants relate that although Metis was of an earlier generation of the Titans, Zeus became her consort when his cult gained dominance. In order to avoid a prophecy made when that change occurred, that any offspring of his union with Metis would be greater than he, Zeus swallowed Metis to prevent her from having offspring, but she already was pregnant with Athena. Metis gave birth to Athena and nurtured her inside Zeus until Athena burst forth from his forehead fully armed with weapons given by her mother. Late Classical Greek myths most commonly describe Athena as the "daughter" of Zeus, born from his head after he swallowed her pregnant mother. She famously wields the thunderbolt and the Aegis, which she and Zeus share exclusively. The Olympian version After he swallowed her pregnant mother, Metis, Athena is "born" from Zeus' forehead as he grasps the clothing of Eileithyia on the right —black-figured amphora, 550–525 BC, Louvre. Although at Mycenaean Knossos Athena appears before Zeus does —in Linear B, as a-ta-na po-ti-ni-ja, "Mistress Athena"— Knossos tablet V 52 (John Chadwick, The Mycenaean World [Cambridge] 1976:88 fig 37. Athana Potnia does not appear at Mycenaean Pylos, where the mistress goddess is ma-te-re te-i-ja, Mater Theia, literally "Mother Goddess".</ref> in the Classical Olympian pantheon, Athena instead appears as the favorite daughter of Zeus, born fully armed from his forehead after he swallowed her mother, Metis. Jane Ellen Harrison's famous characterisation of this myth-element as, "a desperate theological expedient to rid an earth-born Kore of her matriarchal conditions" has never been refuted (Harrison 1922:302). The story of her birth comes in several versions. In the one most commonly cited, Zeus lay with Metis, the goddess of crafty thought and wisdom, but he immediately feared the consequences. Prophecy claimed that Metis would bear children more powerful than the sire, Compare the prophecy concerning Thetis. even Zeus himself. In order to forestall these dire consequences, after lying with Metis, Zeus "put her away inside his own belly;" he "swallowed her down all of a sudden." Hesiod, Theogony 890ff and 924ff. He was too late: Metis already conceived. Minoan labrys, 2nd millennium BC. Eventually Zeus experienced great pain; Prometheus, Hephaestus, Hermes, or Palaemon (depending on the sources examined) cleaved Zeus's head with the double-headed Minoan axe, the labrys. Athena leaped from Zeus's head, fully grown and armed — with a shout, "and pealed to the broad sky her clarion cry of war. And Ouranos trembled to hear, and Mother Gaia..." (Pindar, Seventh Olympian Ode). Plato attributes the cult of Athena to the Minoan culture of Crete, introduced from Libya during the dawn of Greek culture. Classical myths thereafter note that Hera was so annoyed at Zeus producing a child —apparently on his own— that she caused herself to conceive and bear Hephaestus by herself. After the appearance of this variant Metis thereafter never bore any more children and Zeus persisted as supreme ruler of Mount Olympus. Other origin tales Fragments attributed by the Christian Eusebius of Caesarea to the semi-legendary Phoenician historian Sanchuniathon, which Eusebius thought had been written before the Trojan war, make Athena instead, the daughter of Cronus, a king of Byblos who visited 'the inhabitable world' and bequeathed Attica to Athena.

Cory, 1832: "The Theology of the Phœnicians from Sanchoniatho" Sanchuniathon's account would make Athena the sister of Zeus and Hera, not Zeus' daughter. Pallas Athena The major competing tradition regarding Athena's parentage involves some of her more mysterious epithets: Pallas, as in Ancient Greek (also Pallantias) and Tritogeneia (also Trito, Tritonis, Tritoneia, Tritogenes). A separate entity named Pallas is invoked—whether Athena's father, sister, foster-sister, companion, or opponent in battle. In every case, Athena kills Pallas, accidentally, and thereby gains the name for herself. When Pallas is Athena's father the events, including her birth, are located near a body of water named Triton or Tritonis, the result of an etymology of Tritogeneia from Tritonis. When Pallas is Athena's sister or foster-sister, Athena's father or foster-father is Triton, the son and herald of Poseidon. But Athena may be called the daughter of Poseidon and a nymph named Tritonis, without involving Pallas. Likewise, Pallas may be Athena's father or opponent, without involving Triton. Graves, Robert, The Greek Myths I, "The Birth of Athena", 8.a., p. 51. The story comes from Libyan (modern Berbers) where the Greek Athena and the Egyptian Neith blend into one deity. The story is not so often referenced because some facts contradict other better-documented facts. Frazer, vol. 2 p.41 On this topic, Walter Burkert says "she is the Pallas of Athens, Pallas Athenaie, just as Hera of Argos is Here Argeie. Burkert, p. 139. For the Athenians, Burkert notes, Athena was simply "the Goddess", he thea, certainly an ancient title. Athena Parthenos: Virgin Athena Athena never had a consort or lover and thus, also was known as Athena Parthenos, "Virgin Athena." Her most famous temple, the Parthenon, on the Acropolis in Athens takes its name from this title. It was not merely an observation of her virginity, but a recognition of her role as enforcer of rules of sexual modesty and ritual mystery. This role is expressed in a number of stories about Athena. Marinus reports that when Christians removed the statue of the Goddess from the Parthenon, a beautiful woman appeared in a dream to Proclus, a devotee of Athena, and announced that the "Athenian Lady" wished to dwell with him. Marinus of Samaria, "The Life of Proclus or Concerning Happiness", Translated by Kenneth S. Guthrie (1925), pp.15–55:30, retrieved 21 May 2007.Marinus, Life of Proclus Erichthonius Hephaestus attempted to rape Athena, but she eluded him. His semen fell on the ground, and Erichthonius was born from the Earth, Gaia. Athena then raised the baby as a foster mother.<ref>Pseudo-Apollodorus, Bibliotheke 3.14.6. Athena put the infant Erichthonius in a small box (cista) which she entrusted to the care of three sisters, Herse, Pandrosus, and Aglaulus of Athens. The goddess did not tell them what the box contained, but warned them not to open it until she returned. One or two sisters opened the cista to reveal Erichthonius, in the form (or embrace) of a serpent. The serpent, or insanity induced by the sight, drove Herse and Pandrosus to throw themselves off the Acropolis. Graves, Robert, The Greek Myths I, "The Nature and Deeds of Athena" 25.d. Jane Harrison (Prolegomena) finds this to be a simple cautionary tale directed at young girls carrying the cista in the Thesmophoria rituals, to discourage them from opening it outside the proper context. Another version of the myth of the Athenian maidens is told in Metamorphoses by the Roman poet Ovid (43 BC – 17 AD); in this late variant Hermes falls in love with Herse. Herse, Aglaulus, and Pandrosus go to the temple to offer sacrifices to Athena. Hermes demands help from Aglaulus to seduce Herse. Aglaulus demands money in exchange. Hermes gives her the money the sisters had already offered to Athena. As punishment for Aglaulus's greed, Athena asks the goddess Envy to make Aglaulus jealous of Herse. When Hermes arrives to seduce Herse, Aglaulus stands in his way instead of helping him as she had agreed. He turns her to stone. Ovid, Metamorphoses, X. Aglaura, Book II, 708–751; XI. The Envy, Book II, 752–832. With this mythic origin, Erichthonius became the founder-king of Athens, where many beneficial changes to Athenian culture were ascribed to him. During this time, Athena frequently protected him. Medusa and Tiresias In a late myth, Medusa, unlike her two sister-Gorgons, came to be thought of by the Classical Greeks during the fifth century as mortal and extremely beautiful, but she had sex with —or was raped by— Poseidon in a temple of Athena. Upon discovering the desecration of her temple, Athena changed Medusa's form to match that of her sister Gorgons as punishment. Medusa's hair turned into snakes, her lower body was transformed also, and meeting her gaze would turn any living creature to stone. In the earliest of myths there is but one Gorgon and the only snakes were two wrapped around her waist as a belt. In one version of the Tiresias myth, Tiresias stumbled upon Athena bathing, and was blinded by her nakedness. Graves, Robert, The Greek Myths I",The Nature and Deeds of Athena" 25.g. The myth of Actaeon is a doublet of this element. To compensate him for his loss, she sent serpents to lick his ears, which gave him the gift of prophecy. Lady of Athens Athena competed with Poseidon to be the patron deity of Athens, which was yet unnamed, in a version of one founding myth. They agreed that each would give the Athenians one gift and that the Athenians would choose the gift they preferred. Poseidon struck the ground with his trident and a spring sprang up; this gave them a means of trade and water —Athens at its height was a significant sea power, defeating the Persian fleet at the Battle of Salamis— but the water was salty and not very good for drinking. (In an alternate version, Poseidon offered the first horse to the citizens, but horses also are associated with Athena in some myths.) Athena, however, offered them the first domesticated olive tree. The Athenians (or their king, Cecrops) accepted the olive tree and with it the patronage of Athena, for the olive tree brought wood, oil, and food. Robert Graves was of the opinion that "Poseidon's attempts to take possession of certain cities are political myths" which reflect the conflict between matriarchical and patriarchical religions. Graves 1960:16.3p 62. Athena also was the patron goddess of several other Greek cities, notably, Sparta. Helmeted Athena, of the Velletri type; a Roman copy (first century) of a Greek original by Kresilas, c. 430 BC. Athena and Herakles on an Attic red-figure kylix, 480–470 BCE. Counselor Later myths of the Classical Greeks relate that Athena guided Perseus in his quest to behead Medusa. She instructed Heracles to skin the Nemean Lion by using its own claws to cut through its thick hide. She also helped Heracles to defeat the Stymphalian Birds, and to navigate the underworld so as to capture Cerberos. In another late story, it is said that Odysseus' cunning and shrewd nature quickly won Athena's favour. In the realistic epic mode, however, she largely is confined to aiding him only from afar, as by implanting thoughts in his head during his journey home from Troy. It is not until he washes up on the shore of an island where Nausicaa is washing her clothes that Athena arrives personally to provide more tangible assistance. She appears in Nausicaa's dreams to ensure that the princess rescues Odysseus and plays a role in his eventual escort to Ithaca. Athena appears in disguise to Odysseus upon his arrival, initially lying and telling him that Penelope, his wife, has remarried and that he is believed to be dead; but Odysseus lies back to her, employing skillful prevarications to protect himself. Trahman in Phoenix, p. 35. Impressed by his resolve and shrewdness, she reveals herself and tells him what he needs to know in order to win back his kingdom. She disguises him as an elderly man or beggar so that he cannot be noticed by the suitors or Penelope, and helps him to defeat the suitors. She also plays a role in ending the resultant feud against the suitors' relatives. Roman fable of Arachne The fable of Arachne is a late Roman addition to Classical Greek mythology, The tale is recorded in Ovid's Metamorphoses ( (vi.5-54 and 129-145) and mentioned in Virgil's Georgics, iv, 246. that, of course, does not appear in the myth repertory of the Attic vase-painters. Arachne's name simply means spider (αράχνη). Arachne was the daughter of a famous dyer in Tyrian purple in Hypaipa of Lydia. She became so conceited of her skill as a weaver that she began claiming that her skill was greater than that of Athena herself. Athena gave Arachne a chance to redeem herself by assuming the form of an old woman and warning Arachne not to offend the deities. Arachne scoffed and wished for a weaving contest, so she could prove her skill. Athena wove the scene of her victory over Poseidon that had inspired her patronage of Athens. According to the Latin narrative, Arachne's tapestry featured twenty-one episodes of the infidelity of the deities: Zeus being unfaithful with Leda, with Europa, with Danaë. Athena admitted that Arachne's work was flawless, but was outraged at Arachne's disrespectful choice of subjects that displayed the failings and transgressions of the deities. This takes for granted a late, moralizing view of Greek myth. Finally, losing her temper, Athena destroyed Arachne's tapestry and loom, striking it with her shuttle, Arachne realized her folly and hanged herself. In Ovid's telling, Athena took pity on Arachne who was changed into a spider. The fable suggests that the origin of weaving lay in imitation of spiders and that it was considered to have been perfected first in Asia Minor. Cult and attributes Helmeted Athena with the cista and Erichthonius in his serpent form. Roman, first century (Louvre Museum). Athena's epithets include , Atrytone (= the unwearying), , Parthénos (= virgin), and , Promachos (the First Fighter, i. e. she who fights in front). In poetry from Homer, an oral tradition of the eighth or seventh century BC, onward, Athena's most common epithet is glaukopis (γλαυκώπις), which usually is translated as, bright-eyed or with gleaming eyes. Henry George Liddell, Robert Scott, 1940, A Greek-English Lexicon, ISBN 0-19-864226-1, online version at the Perseus Project. The word is a combination of glaukos (γλαύκος, meaning gleaming, silvery, and later, bluish-green or gray) and ops (ώψ, eye, or sometimes, face). It is interesting to note that glaux (γλαύξ, "owl") is from the same root, presumably because of the bird's own distinctive eyes. The bird which sees well in the night is closely associated with the goddess of wisdom: in archaic images, Athena is frequently depicted with an owl perched on her head. The olive tree is likewise sacred to her. In earlier times, Athena may well have been a bird goddess, similar to the unknown goddess depicted with owls, wings, and bird talons on the Burney relief, a Mesopotamian terracotta relief of the early second millennium BC. Other epithets include: Aethyta under which she was worshiped in Megara. Pausanias, i. 5. § 3; 41. § 6 The word aithyia () signifies a diver, and figuratively, a ship, so the name must reference Athena teaching the art of shipbuilding or navigation. John Tzetzes, ad Lycophr., l.c. In a temple at Phrixa in Elis, which was reportedly built by Clymenus, she was known as Cydonia. Smith, Dictionary of Greek and Roman Biography and Mythology. Epithets In the Iliad (4.514), the Homeric Hymns, and in Hesiod's Theogony, Athena is given the curious epithet Tritogeneia. The meaning of this term is unclear. It seems to mean "Triton-born", perhaps indicating that the sea-deity was her parent according to some early myths, Karl Kerenyi suggests that "Tritogeneia did not mean that she came into the world on any particular river or lake, but that she was born of the water itself; for the name Triton seems to be associated with water generally." (Kerenyi, p. 128). or, less likely, that she was born near Lake Triton in Africa. This is the same location noted in The Greek Myths (8.a ff.), by Robert Graves as the possible location from which the worship of Neith was imported into Crete and then into Greece as the warrior goddess Athena at a very early date, perhaps as early as 3,500 BC. Another possible meaning may be triple-born or third-born, which may refer to a triad or to her status as the third daughter of Zeus or the fact she was born from Metis, Zeus, and herself; various legends list her as being the first child after Artemis and Apollo, though other legends identify her as Zeus' first child. The latter would have to be drawn from Classical myths, however, rather than earlier ones. In her role as judge at Orestes' trial on the murder of his mother, Clytemnestra (which he won), Athena won the epithet Athena Areia. [[Image:Peplos scene BM EV.JPG|thumb|left|A new peplos was woven for Athena and ceremonially brought to dress her cult image (British Museum).]] Other epithets were Ageleia and Itonia. The Parthenon, Temple of Athena Parthenos. Athena was given many other cult titles. She had the epithet Athena Ergane as the patron of craftsmen and artisans. With the epithet Athena Parthenos ("virgin"), Athena was worshiped on the Classical period Acropolis, especially in the festivals of the Panathenaea and Pamboeotia. With the epithet Athena Promachos she led in battle. With the epithet Athena Polias ("of the city"), Athena was the protector of Athens and its Acropolis, but also of many other cities, including Argos, Sparta, Gortyn, Lindos, and Larisa. She was given the epithet Athena Hippeia or Athena Hippia, horse as the inventor of the chariot, and was worshipped under this title at Athens, Tegea and Olympia. As Athena Hippeia she was given an alternative parentage: Poseidon and Polyphe, daughter of Oceanus. POLYPHE: Oceanid nymph of Rhodes in the Aegean; Greek mythology TITLES OF ATHENA: Ancient Greek religion . In each of these cities her temple frequently was the major temple on the acropolis. Burkert, p. 140. Athena often was equated with Aphaea, a local goddess of the island of Aegina, located near Athens, once Aegina was under Athenian's power. The Greek historian Plutarch (46 AD–120 AD) also refers to an instance during the Parthenon's construction of her being called Athena Hygieia ("healer"): In classical times the Plynteria, or “Feast of Adorning”, was observed every May, it was a festival lasting five days. During this period the Priestesses of Athena, or “Plyntrides”, performed a cleansing ritual within “the Erecththeum”, the personal sanctuary of the goddess. Here Athena's statue was undressed, her clothes washed, and body purified. In Arcadia, she was assimilated with the ancient goddess Alea and worshiped as Athena Alea. In Classical art The Athena Giustiniani, a Roman copy of a Greek statue of Pallas Athena with her serpent, Erichthonius. Athena depicted on a coin of Attalus I, ruler of Pergamon —c. 200 BC. Classically, Athena is portrayed wearing full armor, with her helmet raised high on the forehead to reveal the image of Nike. Her shield bears at its centre the gorgoneion, the head of the gorgon, as does her aegis. It is in this standing posture that she was depicted in Phidias's famous lost gold and ivory statue of her, 36 m tall, the Athena Parthenos in the Parthenon. Athena also often is depicted with an owl sitting on one of her shoulders. The owl's role as a symbol of wisdom originates in this association with Athena. The Mourning Athena is a relief sculpture that dates around 460 BC and portrays a weary Athena resting on a staff. In earlier, archaic portraits of Athena in Black-figure pottery, the goddess retains some of her Minoan-Mycenaean character, such as great bird wings although this is not true of archaic sculpture such as those of Aphaean Athena, where Athena has subsumed an earlier, invisibly numinous —Aphaea— goddess with Cretan connections in her mythos. Other commonly received and repeated types of Athena in sculpture may be found in this list. Apart from her attributes, there seems to be a relative consensus in late sculpture from the Classical period, the fifth century onward, as to what Athena looked like. Most noticeable in the face is perhaps the full round strong chin with a high nose that has a high bridge as a natural extension of the forehead. The eyes typically are somewhat deeply set. The unsmiling lips are usually full, but the mouth is fairly narrow, usually just slightly wider than the nose. The neck is somewhat long. The net result is a serene, serious, somewhat aloof beauty. Name, etymology, and origin Athena had a special relationship with Athens, as is shown by the etymological connection of the names of the goddess and the city. Athena was said to have won a contest with Poseidon, god of the Sea, over the city of Athens. In Classical myths Zeus had decided that, in order to settle the feud, whoever gave the city the most useful gift would win ownership and patronage of the city. Poseidon gave the city a fountain of flowing water, but it was salty and was not much help to the people. Athena planted the first olive tree, which provided the people with food, firewood, and shade. She showed how to crush olives to make oil, that could then be used in a variety of ways. Athena's gift was the most useful, and she won patronage of the city. Athens was then named in her honor. "Whether the goddess was named after the city or the city after the goddess is an ancient dispute" (Burkert, p. 139). The citizens of Athens built a statue of Athena as a temple to the goddess, which had piercing eyes, a helmet on her head, attired with an aegis or cuirass, and an extremely long spear. It also had a crystal shield with the head of the Gorgon on it. A large snake accompanied her and she held the goddess of victory in her hand. Bust of Athena in the Munich Glyptothek Athena is associated with Athens, a plural name because it was the place where she presided over her sisterhood, the Athenai, in earliest times: "[Mycenae] was the city where the Goddess was called Mykene, and Mycenae is named in the plural for the sisterhood of females who tended her there. At Thebes she was called Thebe, and the city again a plural, Thebae (or Thebes, where the "s" is the plural formation). Similarly, at Athens she was called Athena, and the city Athenae (or Athens, again a plural)." Ruck and Staples 1994:24. Whether her name is attested in Eteocretan or not will have to wait for decipherment of Linear A. Günther Neumann has suggested that Athena's name is possibly of Lydian origin; Günther Neumann, "Der lydische Name der Athena. Neulesung der lydischen Inschrift Nr. 40" Kadmos 6 (1967). it may be a compound word derived in part from Tyrrhenian "ati", meaning mother and the name of the Hurrian goddess "Hannahannah" shortened in various places to "Ana" . In Mycenaean Greek, at Knossos a single inscription A-ta-na po-ti-ni-ja /Athana potniya/ appears in the Linear B tablets from the Late Minoan II-era "Room of the Chariot Tablets"; these comprise the earliest Linear B archive anywhere. Kn V 52 (text 208 in Ventris and Chadwick). Although Athana potniya often is translated Mistress Athena, it literally means "the potnia of At(h)ana", which perhaps, means the Lady of Athens; Palaima, p. 444. Any connection to the city of Athens in the Knossos inscription is uncertain. Burkert, p. 44. We also find A-ta-no-dju-wa-ja /Athana diwya/, the final part being the Linear B spelling of what we know from Ancient Greek as Diwia (Mycenaean di-u-ja or di-wi-ja): divine Athena also was a weaver and the deity of crafts. (see dyeus). Ventris and Chadwick [page missing] In his dialogue Cratylus, the Greek philosopher Plato, 428/427 BC – 348/347 BC, gives the etymology of Athena's name, based on the view of the ancient Athenians: {{quote|That is a graver matter, and there, my friend, the modern interpreters of Homer may, I think, assist in explaining the view of the ancients. For most of these in their explanations of the poet, assert that he meant by Athena "mind" [nous] and "intelligence" [dianoia], and the maker of names appears to have had a singular notion about her; and indeed calls her by a still higher title, "divine intelligence" [Thou noesis], as though he would say: This is she who has the mind better than others. Nor shall we be far wrong in supposing that the author of it wished to identify this Goddess with moral intelligence [en ethei noesin], and therefore gave her the name ethonoe; which, however, either he or his successors have altered into what they thought a nicer form, and called her Athena.|Plato, Cratylus, 407b}} Thus for Plato her name was to be derived from Greek Ἀθεονόα, Atheonóa —which the later Greeks rationalised as from the deity's (theos) mind (nous). The Greek historian, Herodotus (c. 484–425 BC), noted that the Egyptian citizens of Sais in Egypt worshipped a goddess whose Egyptian name was Neith; "The citizens have a deity for their foundress; she is called in the Egyptian tongue Neith, and is asserted by them to be the same whom the Hellenes call Athena; they are great lovers of the Athenians, and say that they are in some way related to them". ( Timaeus 21e) and they identified her with Athena. (Timaeus 21e), (Histories 2:170–175). Some authors believe that, in early times, Athena was either an owl herself or a bird goddess in general: in Book 3 of the Odyssey, she takes the form of a sea-eagle. These authors argue that she dropped her prophylactic owl-mask before she lost her wings. "Athena, by the time she appears in art," Jane Ellen Harrison had remarked, "has completely shed her animal form, has reduced the shapes she once wore of snake and bird to attributes, but occasionally in black-figure vase-paintings she still appears with wings." Harrison 1922:306. (Harrison 1922:307 fig. 84: detail of a cup in the Faina collection). Some authors claim that her tasselled aegis may be the remnants of wings. Others believe that it is scaly, indicating that it is snakeskin. In post-classical culture A neoclassical statue of Athena stands in front of the Austrian Parliament Building in Vienna. Athena (Minerva) is the subject of the $50 1915-S Panama-Pacific commemorative coin. At 2.5 troy oz (78 g) gold, this is the largest (by weight) coin ever produced by the U.S. Mint. This was the first $50 coin issued by the U.S. Mint and no higher was produced until the production of the $100 platinum coins in 1997. Of course, in terms of face-value in adjusted dollars, the 1915 is the highest denomination ever issued by the U.S. Mint. Athena was depicted on the obverse of the Greek 100 drachmas banknote of 1978-2001. Bank of Greece. Drachma Banknotes & Coins: 100 drachmas. – Retrieved on 27 March 2009. For over a century a full-scale replica of the Parthenon has stood in Nashville, Tennessee, which is known as the Athens of the South. In 1990, a gilded 41 feet (12.5 m) tall replica of Phidias' statue of Athena Parthenos was added. The state seal of California features an image of Athena (or Minerva) kneeling next to a brown grizzly bear. LearnCalifornia.org - Symbols of the Seal of California Athena is the symbol of the Darmstadt University of Technology, Germany. The title character in Edgar Allan Poe's "The Raven" famously sits upon "a Bust of Pallas". She is the symbol of the United States Women's Navy and was depicted on their Unit Crest. A medal awarded to women who served in the Women Army Auxiliary Corps from 10 July 1942 to 31 August 1943, and to the Women Army Corps from 1 September 1943 to 2 September 1945 featured Athena on the front. The statue of Renan in Tréguier. Athena's Helmet is the central feature on the United States Military Academy crest. Athena is reported as a source of influence for feminist theologians such as Carol P. Christ. Pallas Athena is the tutelary goddess of the international social fraternity Phi Delta Theta. Her owl is also a symbol of the fraternity. The goddess also holds a special place in the traditions at Bryn Mawr College in Pennsylvania. A statue of Athena (a replica of the original bronze one in the archaeology library) resides in the Great Hall. It is traditional at exam time for students to leave offerings to the goddess with a note asking for good luck, or to repent for accidentally breaking any of the college's numerous other traditions. Athena's owl also serves as the mascot of the college. A statue of the seated skeptical thinker Ernest Renan, shown to the left, caused great controversy when it was installed in Tréguier, Brittany. Renan's 1862 biography of Jesus had denied his divinity, and he had written the Prayer on the Acropolis addressed to the goddess Athena. The statue was placed next to the cathedral. Renan's head was turned away from the building, while Athena, beside him, was depicted raising her arm, which has been interpreted by some to indicate a challenge to the church. The installation was accompanied by a mass protest from local Roman Catholics and a religious service against the growth of skepticism and secularism. Musee Virtuel Jean Boucher See also 60 Years of the Second Republic commemorative coin featuring Athena. Athena has been used numerous times as a symbol of a republic by different countries. A recent sample is the 60 Years of the Second Republic commemorative coin issued by Austria in 2005. Athena is depicted in the obverse of the coin, representing the Austrian Republic.

7,736 | Demographics_of_Botswana | This article is about the demographic features of the population of Botswana, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. Demographics of Botswana, Data of FAO, year 2005 ; Number of inhabitants in thousands. Botswana, like many nations in southern Africa, suffers from a high AIDS infection rates, estimated in a 2002 UN report to be 38.8% for adults. This could be an exaggeration as the UN and other reputable international institutions wrongly estimated 20-25% HIV infection rates in neighboring South Africa up until 2002. These estimates were revised to 11% after the publication of the 2002 Nelson Mandela study of HIV/AIDS prevalence in South Africa . The numbers quoted here about the demographic impact of AIDS in Botswana (such as negative population growth) should be approached with this qualification in mind. Demographic data from the 2001 Botswana census are included for comparison with 2006 CIA estimates. CIA World Factbook demographic statistics Population pyramid The following demographic statistics are from the 2006 CIA World Factbook. Selected demographic data from the 2001 Botswana census is included for comparison. Population 1,680,863 (2001) 1,639,833 (2006 est.) 1,815,508 (2007 est.) Note: estimates for this country explicitly take into account the effects of excess mortality due to AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population and growth rates, and changes in the distribution of population by age and sex than would otherwise be expected.

7,737 | Ethics | Ethics is a branch of philosophy which seeks to address questions about morality, such as what the fundamental semantic, ontological, and epistemic nature of ethics or morality is (meta-ethics), how moral values should be determined (normative ethics), how a moral outcome can be achieved in specific situations (applied ethics), how moral capacity or moral agency develops and what its nature is (moral psychology), and what moral values people actually abide by (descriptive ethics). Meta-ethics Meta-ethics is concerned primarily with the meaning of ethical judgments and/or prescriptions and with the notion of which properties, if any, are responsible for the truth or validity thereof. Meta-ethics as a discipline gained attention with G.E. Moore's famous work Principia Ethica from 1903 in which Moore first addressed what he referred to as the naturalistic fallacy. Moore's rebuttal of naturalistic ethics, his Open Question Argument sparked an interest within the analytic branch of western philosophy to concern oneself with second order questions about ethics; specifically the semantics, epistemology and ontology of ethics. The semantics of ethics divides naturally into descriptivism and non-descriptivism. Descriptivism holds that ethical language (including ethical commands and duties) is a subdivision of descriptive language and has meaning in virtue of the same kind of properties as descriptive propositions. Non-descriptivism contends that ethical propositions are irreducible in the sense that their meaning cannot be explicated sufficiently in terms of descriptive truth-conditions. Correspondingly, the epistemology of ethics divides into cognitivism and non-cognitivism; a distinction that is often perceived as equivalent to that between descriptivists and non-descriptivists. Non-cognitivism may be understood as the claim that ethical claims reach beyond the scope of human cognition or as the (weaker) claim that ethics is concerned with action rather than with knowledge. Cognitivism can then be seen as the claim that ethics is essentially concerned with judgments of the same kind as knowledge judgments; namely about matters of fact. The ontology of ethics is concerned with the idea of value-bearing properties, i.e. the kind of things or stuffs that would correspond to or be referred to by ethical propositions. Non-descriptivists and non-cognitivists will generally tend to argue that ethics do not require a specific ontology, since ethical propositions do not refer to objects in the same way that descriptive propositions do. Such a position may sometimes be called anti-realist. Realists on the other hand are left with having to explain what kind of entities, properties or states are relevant for ethics, and why they have the normative status characteristic of ethics. Normative ethics Traditionally, normative ethics (also known as moral theory) was the study of what makes actions right and wrong. These theories offered an overarching moral principle to which one could appeal in resolving difficult moral decisions. At the turn of the 20th century, moral theories became more complex and are no longer concerned solely with rightness and wrongness, but are interested in many different kinds of moral status. During the middle of the century, the study of normative ethics declined as meta-ethics grew in prominence. This focus on meta-ethics was in part caused by an intense linguistic focus in analytic philosophy and by the popularity of logical positivism. In 1971, John Rawls published A Theory of Justice, noteworthy in its pursuit of moral arguments and eschewing of meta-ethics. This publication set the trend for renewed interest in normative ethics. Greek philosophy Socrates Socrates was one of the first Greek philosophers to encourage both scholars and the common citizen to turn their attention from the outside world to the condition of man. In this view, Knowledge having a bearing on human life was placed highest, all other knowledge being secondary. Self-knowledge was considered necessary for success and inherently an essential good. A self-aware person will act completely within their capabilities to their pinnacle, while an ignorant person will flounder and encounter difficulty. To Socrates, a person must become aware of every fact (and its context) relevant to his existence, if he wishes to attain self-knowledge. He posited that people will naturally do what is good, if they know what is right. Evil or bad actions, are the result of ignorance. If a criminal were truly aware of the mental and spiritual consequences of his actions, he would neither commit nor even consider committing them. Any person who knows what is truly right will automatically do it, according to Socrates. While he correlated knowledge with virtue, he similarly equated virtue with happiness. The truly wise man will know what is right, do what is good and therefore be happy. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pp 32-33. Barnes and Noble Books (1993). ISBN 9781566192712. Aristotle Aristotle posited an ethical system that may be termed "self-realizationism". In Aristotle's view, when a person acts in accordance with his nature and realizes his full potential, he will do good and be content. At birth, a baby is not a person, but a potential person. In order to become a "real" person, the child's inherent potential must be realized. Unhappiness and frustration are caused by the unrealized potential of a person, leading to failed goals and a poor life. Aristotle said, "Nature does nothing in vain." Therefore, it is imperative for persons to act in accordance with their nature and develop their latent talents, in order to be content and complete. Happiness was held to be the ultimate goal. All other things, such as civic life or wealth, are merely means to the end. Self-realization, the awareness of one's nature and the development of one's talents, is the surest path to happiness. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pp 33-35. Barnes and Noble Books (1993). ISBN 9781566192712. Aristotle asserted that man had three natures: vegetable (physical), animal (emotional) and rational (mental). Physical nature can be assuaged through exercise and care, emotional nature through indulgence of instinct and urges, and mental through human reason and developed potential. Rational development was considered the most important, as essential to philosophical self-awareness and as uniquely human. Moderation was encouraged, with the extremes seen as degraded and immoral. For example, courage is the moderate virtue between the extremes of cowardice and recklessness. Man should not simply live, but live well with conduct governed by moderate virtue. This is regarded as difficult, as virtue denotes doing the right thing, to the right person, at the right time, to the proper extent, in the correct fashion, for the right reason. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pp 35-37. Barnes and Noble Books (1993). ISBN 9781566192712. Hedonism Hedonism posits that the principle ethic is maximizing pleasure and minimizing pain. There are several schools of Hedonist thought ranging from those advocating the indulgence of even momentary desires to those teaching a pursuit of spiritual bliss. In their consideration of consequences, they range from those advocating self-gratification regardless of the pain and expense to others, to those stating that the most ethical pursuit maximizes pleasure and happiness for the most people. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pg 37. Barnes and Noble Books (1993). ISBN 9781566192712. Cyrenaic hedonism Founded by Aristippus of Cyrene, Cyrenaics supported immediate gratification. "Eat, drink and be merry, for tomorrow we die." Even fleeting desires should be indulged, for fear the opportunity should be forever lost. There was little to no concern with the future, the present dominating in the pursuit for immediate pleasure. Cyrenaic hedonism encouraged the pursuit of enjoyment and indulgence without hesitation, believing pleasure to be the only good. Epicureanism Epicurus rejected the extremism of the Cyrenaics, believing some pleasures and indulgences to be detrimental to human beings. Epicureans observed that indiscriminate indulgence sometimes resulted in negative consequences. Some experiences were therefore rejected out of hand, and some unpleasant experiences endured in the present to ensure a better life in the future. The summum bonum, or greatest good, to Epicurus was prudence, exercised through moderation and caution. Excessive indulgence can be destructive to pleasure and can even lead to pain. For example, eating one food too often will cause a person to lose taste for it. Eating too much food at once will lead to discomfort and ill-health. Pain and fear were to be avoided. Living was essentially good, barring pain and illness. Death was not to be feared. Fear was considered the source of most unhappiness. Conquering the fear of death would naturally lead to a happier life. Epicurus reasoned if there was an afterlife and immortality, the fear of death was irrational. If there was no life after death, then the person would not be alive to suffer, fear or worry; he would be non-existent in death. It is irrational to fret over circumstances that do not exist, such as one's state in death in the absence of an afterlife. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pp 37-38. Barnes and Noble Books (1993). ISBN 9781566192712. Stoicism The Stoic philosopher Epictetus posited that the greatest good was contentment and serenity. Peace of mind, or Apatheia, was of the highest value; self-mastery over one's desires and emotions leads to spiritual peace. The "unconquerable will" is central to this philosophy. The individual will should be independent and inviolate. Allowing a person to disturb the mental equilibrium is in essence offering yourself in slavery. If a person is free to anger you at will, you have no control over your internal world, and therefore no freedom. Freedom from material attachments is also necessary. If a thing breaks, the person should not be upset, but realize it was a thing that could break. Similarly, if someone should die, those close to them should hold to their serenity because the loved one was made of flesh and blood destined to death. Stoic philosophy says to accept things that cannot be changed, resigning oneself to existence and enduring in a rational fashion. Death is not feared. People do not "lose" their life, but instead "return", for they are returning to God (who initially gave what the person is as a person). Epictetus said difficult problems in life should not be avoided, but rather embraced. They are spiritual exercises needed for the health of the spirit, just as physical exercise is required for the health of the body. He also stated that sex and sexual desire are to be avoided as the greatest threat to the integrity and equilibrium of a man's mind. Abstinence is highly desirable. Epictetus said remaining abstinent in the face of temptation was a victory for which a man could be proud. Sahakian, William S. & Sahakian, Mabel Lewis. Ideas of the Great Philosophers. pp 38-41. Barnes and Noble Books (1993). ISBN 9781566192712. Applied ethics Applied ethics is a discipline of philosophy that attempts to apply ethical theory to real-life situations. The discipline has many specialized fields, such as bioethics and business ethics. The lines of distinction between meta-ethics, normative ethics, and applied ethics are often blurry. For example, the issue of abortion can be seen as an applied ethical topic since it involves a specific type of controversial behaviour. But it can also depend on more general normative principles, such as possible rights of self-rule and right to life, principles which are often litmus tests for determining the morality of that procedure. The issue also rests on meta-ethical issues such as, "where do rights come from?" and "what kind of beings have rights?" Another concept which blurs ethics is moral luck. A drunk driver may safely reach home without injuring anyone, or he might accidentally kill a child who runs out into the street while he is driving home. The action of driving while drunk is usually seen as equally wrong in each case, but its dependence on chance affects the degree to which the driver is held responsible. Specific questions Applied ethics is used in some aspects of determining public policy. The sort of questions addressed by applied ethics include: "Is getting an abortion immoral?" "Is euthanasia immoral?" "Is affirmative action right or wrong?" "What are human rights, and how do we determine them?" and "Do animals have rights as well?" A more specific question could be: "If someone else can make better out of his/her life than I can, is it then moral to sacrifice myself for them if needed?" Without these questions there is no clear fulcrum on which to balance law, politics, and the practice of arbitration — in fact, no common assumptions of all participants—so the ability to formulate the questions are prior to rights balancing. But not all questions studied in applied ethics concern public policy. For example, making ethical judgments regarding questions such as, "Is lying always wrong?" and, "If not, when is it permissible?" is prior to any etiquette. People in-general are more comfortable with dichotomies (two choices). However, in ethics the issues are most often multifaceted and the best proposed actions address many different areas concurrently. In ethical decisions the answer is almost never a "yes or no", "right or wrong" statement. Many buttons are pushed so that the overall condition is improved and not to the benefit of any particular faction. Post-critique ethics The 20th century saw a remarkable expansion of critical theory and its evolution. The earlier Marxist Theory created a paradigm for understanding the individual, society and their interaction. The Renaissance Enlightened Man had persisted up until the Industrial Revolution when the romantic vision of noble action began to fade. Modernism, exemplified in the literary works of Virginia Woolf and James Joyce, wrote out God, then antihumanists such as Louis Althusser and Michel Foucault and structuralists such as Roland Barthes presided over the death of the author and man himself. As critical theory developed in the later 20th century, post-structuralism queried the existence of reality. Jacques Derrida argued reality was in the linguistic realm, stating ‘There is nothing outside the text’, while Jean Baudrillard theorised that signs and symbols or simulacra had usurped reality, particularly in the consumer world. Post-structuralism and postmodernism are both heavily theoretical and follow a fragmented, anti-authoritarian course which is absorbed in narcissistic and near nihilistic activities. Normative issues are generally ignored. This has led to some opponents of these later movements echoing the critic Jurgen Habermas who fears ‘that the postmodern mood represents a turning away from both political responsibilities and a concern for suffering’(cited in Lyon, 1999, p.103). David Couzens Hoy says that Emmanuel Levinas’ writings on the face of the Other and Derrida’s mediations on the relevance of death to ethics are signs of the ‘ethical turn’ in Continental philosophy that occurs in the 1980’s and 1990’s. Hoy clarifies post-critique ethics as the ‘obligations that present themselves as necessarily to be fulfilled but are neither forced on one or are enforceable’ (2004, p.103). This aligns with Australian philosopher Peter Singer’s thoughts on what ethics is not. He firstly claims it is not a moral code particular to a sectional group. For example it has nothing to do with a set of prohibitions concerned with sex laid down by a religious order. Neither is ethics a ‘system that is noble in theory but no good in practice’ (2000, p.7). For him, a theory is good only if it is practical. He agrees that ethics is in some sense universal but in a utilitarian way it affords the ‘best consequences’ and furthers the interests of those affected (2000, p.15). Hoy in his post-critique model uses the term ethical resistance. Examples of this would be an individual’s resistance to consumerism in a retreat to a simpler but perhaps harder lifestyle, or an individual’s resistance to a terminal illness. Hoy describes these examples in his book Critical Resistance as an individual’s engagement in social or political resistance. He provides Levinas’s account as ‘not the attempt to use power against itself, or to mobilise sectors of the population to exert their political power; the ethical resistance is instead the resistance of the powerless’(2004, p.8). Hoy concludes that "The ethical resistance of the powerless others to our capacity to exert power over them is therefore what imposes unenforceable obligations on us. The obligations are unenforceable precisely because of the other’s lack of power. That actions are at once obligatory and at the same time unenforceable is what put them in the category of the ethical. Obligations that were enforced would, by the virtue of the force behind them, not be freely undertaken and would not be in the realm of the ethical" (2004, p.184). In present day terms the powerless may include the unborn, the terminally sick, the aged, the insane, and animals. It is in these areas that ethical action will be evident. Until legislation or state apparatus enforces a moral order that addresses the causes of resistance these issues will remain in the ethical realm. For example, should animal experimentation become illegal in a society, it will no longer be an ethical issue. Likewise one hundred and fifty years ago, not having a black slave in America may have been an ethical choice. This later issue has been absorbed into the fabric of a more utilitarian social order and is no longer an ethical issue but does of course constitute a moral concern. Ethics are exercised by those who possess no power and those who support them, through personal resistance. Particular fields of application Relational ethics Relational ethics are related to an ethics of care. Gilligan, C. (1982). In a different Voice: Pscychological theory and women's development. Cambridge, MA: Harvard University Press. They are used in qualitative research, especially ethnography and authoethnography. Researchers who employ relational ethics value and respect the connection between themselves and the people they study, and "between researchers and the communities in which they live and work" (Ellis, 2007, p. 4). Ellis, C. (2007). Telling secrets, revealing lives: Relational ethics in research with intimate others. Qualitative Inquiry, 13, 3-29. Relational ethics also help researchers understand difficult issues such as conducting research on intimate others that have died and developing friendships with their participants. Ellis, C. (1986). Fisher folk. Two communities on Chesapeake Bay. Lexington: University Press of Kentucky. Ellis, C. (1995).Final negotiations: A story of love, loss, and chronic illness. Philadelphia: Temple University Press. Military ethics Military ethics is a set of practices and philosophy to guide members of the armed forces to act in a manner consistent with the values and standards as established by military tradition, and to actively clarify and enforce these conditions rigorously in its administrative structure. Military ethics is evolutionary and the administrative structure is modified as new ethical perspectives consistent with national interests evolve. Many issues of ethics involve any country's military establishment, including issues relating to: justification for using force race (loss of capability due to race bias or abuse) gender equality (loss of capability due to gender bias or abuse) age discrimination (authority based upon age instead of accomplishment or productivity) nepotism (unfair control by family members; also known as "empire building") political influence (military members having a political position or political influence) And others. Moral psychology Evolutionary ethics Evolutionary ethics concerns approaches to ethics (morality) based on the role of evolution in shaping human psychology and behavior. Such approaches may be based in scientific fields such as evolutionary psychology or sociobiology, with a focus on understanding and explaining observed ethical preferences and choices. Evolutionary ethics Descriptive ethics Descriptive ethics is a value-free approach to ethics which examines ethics not from a top-down a priori perspective but rather observations of actual choices made by moral agents in practice. Some philosophers rely on descriptive ethics and choices made and unchallenged by a society or culture to derive categories, which typically vary by context. This can lead to situational ethics and situated ethics. These philosophers often view aesthetics, etiquette, and arbitration as more fundamental, percolating "bottom up" to imply the existence of, rather than explicitly prescribe, theories of value or of conduct. The study of descriptive ethics may include examinations of the following: Ethical codes applied by various groups. Some consider aesthetics itself the basis of ethics and a personal moral core developed through art and storytelling as very influential in one's later ethical choices. Informal theories of etiquette which tend to be less rigorous and more situational. Some consider etiquette a simple negative ethics, i.e. where can one evade an uncomfortable truth without doing wrong? One notable advocate of this view is Judith Martin ("Miss Manners"). According to this view, ethics is more a summary of common sense social decisions. Practices in arbitration and law, e.g. the claim that ethics itself is a matter of balancing "right versus right," i.e. putting priorities on two things that are both right, but which must be traded off carefully in each situation. Observed choices made by ordinary people, without expert aid or advice, who vote, buy, and decide what is worth valuing. This is a major concern of sociology, political science, and economics.

7,738 | Australian_Army | The Australian Army is Australia's military land force. It is part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Royal Australian Air Force. While the Chief of Defence (CDF) commands the Australian Defence Force (CDF), the Army is commanded by the Chief of Army (CA). The Chief of Army is therefore subordinate to the CDF, but is also directly responsible to the Minister for Defence. Defence Act (1903) Although Australian soldiers have been involved in a number of minor and major conflicts throughout its history, only in World War II has Australian territory come under direct attack. Mission Australian Government websites state that the Army's mission is to provide a potent, versatile, and updated Army to promote the security of Australia and protect its people. http://www.sacentral.sa.gov.au/site/page.cfm?u=52&area=2&c=43616 Australian Defence Force (ADF) - australia.gov.au Australia in Brief - Department of Foreign Affairs and Trade Further, the Army's key doctrine publication, The Fundamentals of Land Warfare, states that "the Army’s mission is to win the land battle". Orientation The Australian Army is oriented toward low and medium intensity operations against symmetric and asymmetric enemies. The Australian Army has traditionally been structured as a light infantry force. This has changed somewhat in recent years, with an increased emphasis on motorised and mechanized forces. In the next few years, two of the seven regular infantry battalions will be mechanized (using the upgraded M113 APC) and two will be motorised (using the Bushmaster). Even so the motorised and mechanized battalions still train with an orientation toward operations in close combat and have a high emphasis on patrolling and other dismounted operations, thus maintaining the traditional Australian skill set. Until recently the main area of operations has been Asia, particularly South East Asia and the Pacific, so the light infantry orientation has not been a hindrance. In fact the Australian Army is known to produce troops and units with a very high standard of jungle warfare, patrolling, ambushing and other infantry skills. Due to Australia's relatively small population, its Army will always make up only a statistically small role in coalition operations. Successive Australian governments since 1989 have deployed components of the ADF with specific skill sets, so that the Australian contribution is always of greater significance than raw numbers of troops would suggest. Often this has taken the form of the deployment of special forces, though this has changed in recent years, for example in Afghanistan. Australian forces have always trained with and maintained close relationships the US and British forces and are now being equipped to better interoperate with US/British/coalition forces. The defence relationship with US forces is probably now closer than it has been at any point since the Vietnam war, especially at a working level. History A trench at Lone Pine after the battle, showing Australian and Turkish dead on the parapet Soldiers of the Australian 39th Battalion in September 1942 The history of the Australian Army can be divided into two periods: 1901–47, when limits were set on the size of the Regular Army, the vast majority of peacetime soldiers were in the Reserve Army units of the Australian Citizens Military Force (also known as the CMF or Militia), and Australian Imperial Forces were formed to serve overseas, and post-1947, when a standing peacetime infantry force was formed and the CMF (known as the Army Reserve after 1980) began to decline in importance. The army has been involved in many peacekeeping operations, usually under the auspices of the United Nations. The largest one began in 1999 in East Timor. Other notable operations include peacekeeping on Bougainville and in the Solomon Islands, which are still ongoing to this day. Humanitarian relief after 2004 Indian Ocean earthquake in Aceh Province, Indonesia, Operation Sumatra Assist, ended on 24 March 2005. Current deployments ASLAVs in Iraq in 2006 The Australian Army currently has significant forces deployed on four major operations Error Occurred While Processing Request : Operation Catalyst - Australia's commitment to the Coalition forces in Iraq. Operation Kruger - Australia's embassy security detachment which provides security protection and escort for staff at the Australian Embassy in Baghdad, and consists of 100 personnel. Operation Slipper - Australia's commitment to the War on Terror. The army contribution is primarily concentrated in Afghanistan: Mentoring and Reconstruction Task Force; attached to the Dutch-led Provincial Reconstruction Team in Oruzgan Province, this consists of engineers protected by a reinforced infantry company. Operation Astute - Australia's commitment to Timor-Leste. This constitutes the largest overseas deployment of Australian forces, with around 925 troops deployed. These are primarily formed into a single battlegroup: ANZAC Battle Group; this is an infantry heavy battle group supported by engineers, armoured vehicles and combat support elements. Integrated into its structure is a company from the Royal New Zealand Infantry Regiment. Operation Anode - Australia's commitment to the Regional Assistance Mission Solomon Islands (RAMSI) has changed over the years, with an initial influx of over 2000 troops to one Platoon of Australians, New Zealanders and Pacific Islanders just before the riots of April 2006. The current contribution includes, as at December 2007, an Australian Rifle Company, a New Zealand Platoon, a Pacific Islander Country (PIC) Platoon, plus support elements such as Sigs, Transport, Q-Store, Intelligence and Operations Staff. The Military component of the Operation is commanded by a Lt-Col from Australia. In addition to these, small numbers of personnel are deployed on various peacekeeping operations around the world, including the Multinational Force and Observers and to the United Nations. Operation Mazurka - Australia's commitment to Multinational Force and Observers (MFO). From 1982-1986, the RAAF provided rotary wing aviation support. Since 1994 the Australian Army has maintained a presence within the organisation. Currently 25 personnel rotate twice a year, being employed in key HQ, operations and logistics positions. Operation Paladin - is the Army's longest ongoing operation, where Australian personnel have served since 1956. Operation Paladin is Australia's contribution to the UN Truce Supervision Organisation that was established in 1948 to supervise the truce agreed at the conclusion of the first Arab/Israeli War. Current organisation The Australian Army's structure in 2008 (click to enlarge) The Australian Army is currently organised around two Divisional headquarters. The Deployable Joint Force Headquarters/1st Division has responsibility for the majority of the regular army, while 2nd Division is the main home defence formation, containing Army Reserve units. Only the 1st Division's headquarters is deployable, however, as the 2nd Division's headquarters only performs administrative functions. The Australian Army has not deployed a divisional sized formation since 1945 and does not expect to do so in the future. David Horner (2001). Making the Australian Defence Force. Oxford University Press, Melbourne. ISBN 0195541170. Page 195. Expansion plans announced in 2006 will see the Australian Army expand by 2008, resulting in a primary force that is organised around eight battalions of the Royal Australian Regiment - three of these are to be standard light infantry, two mechanised, and two are to be motorised. The final battalion is a specialised commando unit which is part of Special Operations Command. The Royal Australian Armoured Corps presently has four regular regiments, one of main battle tanks and two light cavalry (formation reconnaissance). The fourth consists of a single squadron and is used on the armoured personnel carrier/light armoured role. These forces, together with the associated combat support (artillery, engineers, signals) and combat service support (logistics, maintenance etc) are based around two deployable brigades, 1 Brigade, which is primarily a mechanised formation, and 3 Brigade, which is a light, air deployable formation. 7 Brigade was an integrated Regular/Reserve formation that would primarily be used in conjunction with DJFHQ were it ever to be deployed overseas. As part of the expansion of the regular army, the two reserve infantry battalions were transferred to 11 Brigade in 2nd Division in 2007. The re-formed 8/9 RAR will be assigned to 7 Brigade to make it the third regular brigade. 'Hardened and Networked Army' In 2006, then Australian Minister for Defence, Senator Robert Hill announced that the Australian Army would be restructured and redeveloped in an updated version of the Army’s ‘Hardened Networked Army’ concept. The policy of creating a ‘Hardened and Networked' Army will see a major reorganisation of both the regular Army and Army Reserve. The overriding rationale for this is to bring about "A reduction in singular capabilities that can not be rotated, hence an 'Army of twos'". Hardened and Networked Army This will involve the army being organised so that it can deploy a number of battlegroups, consisting of infantry, armour, artillery etc in the correct proportions relevant to each type of mission. When the reorganisation is complete it is planned that the Army will be able to form battlegroups based around the following formations: 1st Battalion, Royal Australian Regiment, Light infantry Battalion 2nd Battalion, Royal Australian Regiment, Light infantry Battalion 3rd Battalion, Royal Australian Regiment, Parachute infantry Battalion (Re-rolling to Light infantry Battalion) 5th Battalion, Royal Australian Regiment, Mechanised infantry Battalion 6th Battalion, Royal Australian Regiment, Motorised infantry Battalion 7th Battalion, Royal Australian Regiment, Mechanised infantry Battalion 8th/9th Battalion, Royal Australian Regiment, Motorised infantry Battalion 1st Armoured Regiment, Armoured Regiment 2nd Cavalry Regiment, Formation Reconnaissance Regiment 2nd/14th Light Horse Regiment, Formation Reconnaissance Regiment 1st Aviation Regiment, Attack helicopter Regiment By the end of this process in approximately 2015, 1 Brigade will be the army's major mechanised formation. In addition, 1st Division/DJHQ will be reduced to three brigades, with 11 Brigade, a wholly Army Reserve formation, being transferred to the 2nd Division. The armoured units of the Army Reserve in 2nd Division will be restructured, with four becoming pure light cavalry and the fifth being utilised in the armoured lift role. Colours, standards and guidons Governor-General Sir William Deane presents the new Army Banner to the Regimental Sergeant Major of the Army in 2001 All colours of the Army were on parade for the centenary of the Army, 10 March 2001 Infantry, and some other combat units of the Australian Army carry flags called the Queen's colour and the Regimental Colour, known as 'the Colours'. Armoured units carry Guidons - flags smaller than Colours traditionally carried by Cavalry, Lancer, Light Horse and Mounted Infantry units. Artillery units' Guns are considered to be their Colours, and on parade are provided with the same respect. Non-combat units (combat service support corps) do not have Colours, as Colours are battle flags and so are only available to combat units. As a substitute, many have Standards or Banners. Units awarded battle honours have them emblazoned on their Colours, Standards and Guidons. They are a link to the Unit's past and a memorial to the fallen. Artillery do not have Battle Honours. Their single Honour is "Ubique" which means "Everywhere". The Army is the guardian of the National Flag and as such, unlike the Royal Australian Air Force, does not have a flag or Colours. The Army, instead, has a banner, known as the Army Banner. To commemorate the centenary of the Army, the Governor General Sir William Deane, presented the Army with a new Banner at a parade in front of the Australian War Memorial on 10 March 2001. The Banner was presented to the Regimental Sergeant Major of the Army, WO1 Peter Rosemond. The Army banner bears the Australian Coat of Arms on the obverse, with the dates "1901–2001" in gold in the upper hoist. The reverse bears the 'rising sun' badge of the Australian Army, flanked by seven campaign honours on small gold-edged scrolls: South Africa, World War I, World War II, Korea, Malaya-Borneo, South Vietnam, and Peacekeeping. The banner is trimmed with gold fringe, has gold and crimson cords and tassels, and is mounted on a pike with the usual British royal crest finial. Personnel Strength In the 2007-08 financial year the Army had an average strength of 42,503 personnel, including 26,611 permanent (regular) and 15,892 active reservists (part-time). Australian Department of Defence (2008). Pages 99–100. In addition there are another 12,496 members of the Standby Reserve. Rank and insignia The ranks of the Australian Army are based on the ranks of the British Army, and carry mostly the same actual insignia. For officers the ranks are identical except for the shoulder title "Australia". The Non-Commissioned Officer insignia are the same up until Warrant Officer ranks, where they are stylised for Australia (e.g. using the Australian, rather than the British coat of arms). Australian Army officer rank insignia Australian Army enlisted rank insignia Current recruiting issues An infantryman training with a Leopard 1 tank in 2001 On 24 August 2006 the then Prime Minister John Howard announced a requirement for an extra 2600 soldiers for the Australian Army, in addition to a previously announced increase of 1500. Recent remarks of low morale in the Army, a high desire to leave the armed forces for civilian careers amongst serving soldiers, low unemployment figures for school-leavers and university graduates, as well as general opposition for Australian soldiers serving in Iraq have resulted in the Army falling short of its recruiting expectations. This new campaign, which included the raising of two new infantry battalions ready for overseas deployment by 2010, reportedly cost $A10 billion. The first of these new battalions, to be operational by 2008, was formed be the de-amalgamation of 5/7 RAR into the reformed 5th Battalion and 7th Battalion, Royal Australian Regiment. The second battalion to be re-raised was the 8th/9th Battalion, Royal Australian Regiment. Prime Minister John Howard cited causes for this requirement as the threat of unstable, possibly terrorist harbouring states in Australia’s immediate region: The statement drew opposition from the Papua New Guinean Prime Minister, Sir Michael Somare came on 25 August 2006, saying an expansion of the Australian Army would actually be in response to its forces already deployed in the Middle East, and not for the possibility of threat from its Pacific neighbours. On 15 October 2006 the then Defence minister Brendan Nelson announced that the Army will be implementing a new 'try before you buy' recruitment system, reducing the Initial Minimum Period of Service (IMPS) from four years to one year for enlisted soldiers. Aimed at school leavers, this system is designed to reduce the impact of joining the army for recruits entering the work force, making the option of military service more attractive. This is known as the "ADF Gap Year", playing on the term of "gap" where school-leavers take a year off before going to University to study. Foreign nationals with prior military service have also been permitted to join the Australian Army. Australian Army Recruiting - Overseas Applicants Concern that the plan also may result in an overall reduction in the fitness, medical and age restrictions placed on applicants, in order to ‘modernize’ the restrictions and also assist in boosting numbers drew criticism of these plans within some veteran’s organisations. Along with this announcement, arguments for more and better equipment were advanced, with speculation of a possible increase in the numbers of M113 APCs, Bushmaster IMV and M1A1 Abrams tanks being acquired. Indeed in late 2008 additional Bushmasters and upgraded M113s were ordered for the Australian Army in significant numbers. By mid-2007, following an extensive multi-million dollar advertising campaign seeking recruits, there is now a reversal of the situation with high enlistment numbers (exceeding the governments target by 1004 persons) but due to the lack of available and adequate training facilities and personnel more than 85 percent of applicants wait for between 35 days and 6 months to start their training, resulting in dropouts in recruits during this period. In response plans to create a second recruit-training battalion have been put forward, but that may take years to eventuate, if at all.

7,739 | Public_Enemy_(group) | Public Enemy, also known as PE, is an influential hip hop group from Long Island, New York, known for its politically charged lyrics, criticism of the media, and active interest in the concerns of the African American community. In 2004, Rolling Stone Magazine ranked Public Enemy number forty-four on its list of the Immortals: 100 Greatest Artists of All Time. Acclaimed Music ranks them the 29th most recommended musical act of all time and the highest hip-hop group. www.acclaimedmusic.net The group was inducted into the Long Island Music Hall of Fame in 2007. "Long Island Music Hall of Fame" History Origin of name Chuck D had put out a tape to promote WBAU (the radio station where he was working at the time) and to fend off a local emcee who wanted to battle him. He called the tape Public Enemy #1 because he felt like he was being persecuted by people in the local scene. This was the first reference to the notion of a public enemy in any of Chuck D's songs. The single was created by Chuck D with a contribution by Flavor Flav, though this was before the group Public Enemy was officially assembled. Public Enemy is also the name of a 1931 classic gangster movie starring James Cagney. According to Chuck, The S1W, which stands for Security of the First World, "represents that the black man can be just as intelligent as he is strong. It stands for the fact that we're not third-world people, we're first-world people; we're the original people [of the earth]." Chuck D. and Yusuf Jah, Fight the Power, p. 82) On the track "Louder Than a Bomb" from It Takes a Nation of Millions to Hold Us Back, Chuck D reveals that the D in his nickname stands for dangerous. Signing to Def Jam Records Developing his talents as an MC with Flavor Flav while delivering furniture for his father's business, Chuck D (Carlton Douglas Ridenhour) and Spectrum City, as the group was called, released the record "Check out the Radio," backed by "Lies," a social commentary—both of which would influence RUSH Productions' Run-D.M.C. and Beastie Boys. The group was signed to the still developing Def Jam Recordings record label after co-founder Rick Rubin heard Chuck D freestyling on a demo. Around 1986, Bill Stephney, the former Program Director at WBAU, was approached by Rubin and offered a position with the label. Stephney accepted, and his first assignment was to help Rubin sign Chuck D, whose song "Public Enemy Number One" he had heard from Andre "Doctor Dré" Brown. According to the book The History of Rap Music by Cookie Lommel, "Stephney thought it was time to mesh the hard-hitting style of Run DMC with politics that addressed black youth. Chuck recruited Spectrum City, which included Hank Shocklee, his brother Keith Shocklee, and Eric "Vietnam" Sadler, collectively known as the Bomb Squad, to be his production team and added another Spectrum City partner, Professor Griff, to become the group's Minister of Information. With the addition of Flavor Flav and another local mobile DJ named Terminator X, the group Public Enemy was born." Stardom Their debut album, Yo! Bum Rush The Show, was released in 1987 to critical acclaim. The group released the album It Takes a Nation of Millions to Hold Us Back in 1988, which performed better in the charts than their previous release, and included the hit single "Don't Believe the Hype" in addition to "Black Steel in the Hour of Chaos". Nation of Millions... was voted Album of the Year by the The Village Voice Pazz and Jop Poll, the first hip-hop album to be ranked number one by predominantly rock critics in a major periodical. It is also ranked the 18th best album of all time by Acclaimedmusic.net. In 1990, the group released Fear of a Black Planet which continued the politically charged themes. It was also the most successful of any of its albums and, in 2005, was selected for preservation in the Library of Congress. It included the singles "911 (is a Joke)," which criticized emergency response units for taking longer to arrive at emergencies in the black community than those in the white community, and "Fight the Power" Fight The Power Named Best Hip Hop Song, AOL Music Canada . The song is regarded among the most popular and influential in hip-hop history and was the theme song of Spike Lee's Do The Right Thing. It is ranked the 80th best song of all time by Acclaimedmusic.net. "Fight the Power" contains the controversial lines "Elvis was a hero to most/But he never meant shit to me/You see, straight-up racist that sucker was simple and plain/Motherfuck him and John Wayne." The group’s next release, Apocalypse '91...The Enemy Strikes Black, continued this trend, with songs like "Can't Truss It" and "# I Don't Wanna be Called Yo Niga." The album included the controversial song and video "By the Time I Get to Arizona," which chronicled the black community's frustration that some states did not recognize Martin Luther King Jr.'s birthday as a national holiday. The video featured members of Public Enemy taking out their frustrations on politicians in the states not recognizing the holiday. Criticism In 1989, the band did an interview for the Washington Times. The interviewing journalist, David Mills, lifted some quotations from a UK magazine in which the band were asked their opinion on the Arab-Israeli conflict. Professor Griff’s comments apparently sympathized with the Palestinians and, reiterated in the new interview, a media firestorm was set off. Additionally, Griff was accused of anti-Semitism in 1989, when Public Enemy enjoyed unprecedented mainstream attention with their "Fight the Power" single from the soundtrack of Spike Lee's Do the Right Thing. According to Rap Attack 2, he suggested that "Jews are responsible for the majority of the wickedness in the world" (p. 177). He denies the charge to this day, calling it "crazy...really, really, crazy." Despite Griffin's denial, Ridenhour expressed an apology on his behalf. Public Enemy Hip-Hop Group Reorganizes after Anti-Semitic Comments - New York Times In an attempt to defuse the situation, Ridenhour first fired Griffin. He later rejoined the group, but Ridenhour then disbanded the group. When Public Enemy reformed, its members initially did so without Griffin. In the late 1990s, he rejoined the band, and Ridenhour and Griffin took on a side project, the rap rock outfit Confrontation Camp. The controversy and apologies on behalf of Griff spurred Chuck D to reference the negative press they were receiving. In 1990 Public Enemy issued the single "Welcome to the Terrordome", which contains the lyrics: "Crucifixion ain't no fiction / So-called chosen frozen / Apologies made to whoever pleases / Still they got me like Jesus".

Performance at Rhythm & Vines 2008 It was confirmed on 12 November 2008 that the band will be the headline act at Gisborne's annual Rhythm & Vines Concert on 30 December 2008 which will be their only New Zealand performance and to also mark the group's 12th anniversary. Legacy Public Enemy at Vegoose in 2007. From left: DJ Lord, Chuck D, and Flavor Flav. Public Enemy was a pioneering group in many ways. Some of Terminator X's most innovative scratching tricks can be heard on the song "Rebel Without a Pause," and the Bomb Squad offered up a web of innovative samples and beats. Critic Stephen Thomas Erlewine declared that PE "brought in elements of free jazz, hard funk, even musique concrète, via [its] producing team the Bomb Squad, creating a dense, ferocious sound unlike anything that came before." allmusic ((( It Takes a Nation of Millions to Hold Us Back > Overview ))) Public Enemy revolutionized the hip-hop world with its political, social and cultural consciousness, which infused itself into skilled and poetic rhymes with raucous sound collages as a foundation. Prior to PE, political hip-hop was confined to a few tracks by Ice-T, Grandmaster Flash and the Furious Five, and KRS-One, as well as prototypical artists such as Gil Scott-Heron and the Last Poets. PE was the first hip-hop act to base its entire image around a political stance. With the success of Public Enemy, hip-hop was suddenly flooded with new artists that celebrated Afrocentric themes, such as Kool Moe Dee, Gang Starr, X Clan, Eric B. & Rakim, Queen Latifah, the Jungle Brothers, and A Tribe Called Quest. In the 1991 movie Terminator 2: Judgment Day, John Connor (Edward Furlong) wears a Public Enemy t-shirt throughout the entire movie, exhibiting its influence even in mainstream venues. Public Enemy was the first hip-hop group to make extended world tours, which led to huge popularity and influence in hip-hop communities in Europe and Asia. It also changed the Internet's music distribution capability by being one of the first groups to release MP3-only albums, Dubois, Keir. "Public Enemy and MP3". Transcriptions Project, December, 1999. Retrieved on March 17, 2007. a format virtually unknown at the time. Public Enemy helped to create and define "Rap metal" by collaborating with New York Thrash metal outfit Anthrax in 1991. The single "Bring the Noise" was a mix of semi-militant black power lyrics, grinding guitars, and sporadic humor. The two bands, cemented by a mutual respect and the personal friendship between Chuck D and his Anthrax counterpart Scott Ian, introduced a hitherto alien genre to rock fans, and the two seemingly disparate groups even toured together. Flavor Flav's pronouncement on stage that "They said this tour would never happen" (as heard on Anthrax's Live: The Island Years CD) has become something of a legend in both rock and hip-hop circles. Metal guitarists Vernon Reid (of Living Colour) contributed to Public Enemy's recordings, and PE sampled Slayer's "Angel of Death" half-time riff on "She Watch Channel Zero." Members of the Bomb Squad produced or remixed works for other acts such as Bell Biv DeVoe, Ice Cube, Vanessa Williams, Sinéad O'Connor, Blue Magic, Peter Gabriel, L.L. Cool J, Paula Abdul, Jasmine Guy, Jody Watley, Eric B & Rakim, Third Bass, Big Daddy Kane, EPMD, and Chaka Khan. According to Chuck, "We had tight dealings with MCA Records and were talking about taking three guys that were left over from New Edition and coming up with an album for them. The three happened to be Ricky Bell, Michael Bivins, and Ronnie DeVoe, later to become Bell Biv DeVoe. Ralph Tresvant had been slated to do a solo album for years, Bobby Brown had left New Edition and blew up in 1988, (Joe is in public enemy) and Johnny Gill had just been recruited to come in, but [he] had come off a solo career and could always go back to that. At MCA, Hiram Hicks, who was their manager, and Louil Silas, who was running the show, were like, 'Yo, these kids were left out in the cold. Can y'all come up with something for them?' It was a task that Hank, Keith, Eric, and I took on to try to put some kind of hip-hop-flavored R&B shit down for them. Subsequently, what happened in the four weeks of December [1989] was that the Bomb Squad knocked out a large piece of the production and arrangement on Bell Biv DeVoe's three-million selling album Poison. In January [1990], they knocked out Fear of a Black Planet in four weeks, and PE knocked out Ice Cube's album AmeriKKKa's Most Wanted in four to five weeks in February." Fight The Power, pp. 236-237 They have also produced local talent such as Son of Bazerk, Young Black Teenagers, Kings of Pressure, and True Mathematics—and gave producer Kip Collins his start in the business. American Punk rock band NOFX references Public Enemy in their song "Franco Unamerican", stating "I'm watching Michael Moore expose the awful truth/ I'm listening to Public Enemy and Reagan Youth."

7,740 | Flywheel_energy_storage | NASA G2 flywheel Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed. Torotrak Toroidal variable drive CVT, retrieved June 7, 2007. Advanced FES systems have rotors made of high strength carbon-composite filaments, suspended by magnetic bearings, and spinning at speeds from 20,000 to over 50,000 rpm in a vacuum enclosure Castelvecchi, D. (2007). Spinning into control. Science News, vol. 171, pp. 312-313 . Such flywheels can come up to speed in a matter of minutes — much quicker than some other forms of energy storage. Main components A typical system consists of a rotor suspended by bearings inside a vacuum chamber to reduce friction, connected to a combination electric motor/electric generator. Rotor First generation flywheel energy storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fibre composite rotors that have a higher tensile strength than steel and are an order of magnitude lighter. Bearings Magnetic bearings are necessary; in conventional mechanical bearings, friction is directly proportional to speed, and at such speeds, too much energy would be lost to friction. The expense of refrigeration led to the early dismissal of low temperature superconductors for use in magnetic bearings. High-temperature superconductor (HTSC) bearings however may be economical and could possibly extend the time energy could be stored economically. Hybrid bearing systems are most likely to see use first. High-temperature superconductor bearings have historically had problems providing the lifting forces necessary for the larger designs, but can easily provide a stabilizing force. Therefore, in hybrid bearings, permanent magnets support the load and high-temperature superconductors are used to stabilize it. The reason superconductors can work well stabilizing the load is because they are perfect diamagnets. If the rotor tries to drift off center, a restoring force due to flux pinning restores it. This is known as the magnetic stiffness of the bearing. Rotational axis vibration can occur due to low stiffness and damping, which are inherent problems of superconducting magnets, preventing the use of completely superconducting magnetic bearings for flywheel applications. Since flux pinning is the important factor for providing the stabilizing and lifting force, the HTSC can be made much more easily for FES than for other uses. HTSC powders can be formed into arbitrary shapes so long as flux pinning is strong. An ongoing challenge that has to be overcome before superconductors can provide the full lifting force for an FES system is finding a way to suppress the decrease of levitation force and the gradual fall of rotor during operation caused by the flux creep of SC material. Parasitic losses such as friction, hysteresis, and eddy currents of both magnetic and conventional bearings in addition to refrigerant costs can limit the economical energy storage time for flywheels. However, further improvements in superconductors may help eliminate eddy current losses in existing magnetic bearing designs as well as raise overall operating temperatures. Even without such improvements, however, modern flywheels can have a zero-load rundown time measurable in years. (The 'zero-load rundown time' measures how long it takes for the device to come to a standstill when it is not connected to any other devices.) Physical characteristics For the basic physics of a flywheel, see Flywheel Physics. Compared with other ways of storing electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 105, up to 107, cycles of use) Storage Technology Report, ST6 Flywheel , high energy densities (100-130 W·h/kg, or 360-500 kJ/kg) Storage Technology Report, ST6 Flywheel , and large maximum power outputs. The energy efficiency (ratio of energy out per energy in) of flywheels can be as high as 90%. Typical capacities range from 3 kWh to 133 kWh.Rapid charging of a system occurs in less than 15 minutes. Applications Transportation In the 1950s flywheel-powered buses, known as gyrobuses, were used in Yverdon, Switzerland, and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper, and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywheel systems would eliminate many of the disadvantages of existing battery power systems, such as low capacity, long charge times, heavy weight, and short usable lifetimes. Flywheels may have been used in the experimental Chrysler Patriot, though that has been disputed. Allpar - The Chrysler Patriot Flywheel systems have also been used experimentally in small electric locomotives for shunting or switching, e.g. the Sentinel-Oerlikon Gyro Locomotive. Larger electric locomotives, e.g. British Rail Class 70, have sometimes been fitted with flywheel boosters to carry them over gaps in the third rail. Advanced flywheels, such as the 133 kW·h pack of the University of Texas at Austin, can take a train from a standing start up to cruising speed. During the 1990s Rosen Motors developed a gas turbine powered series hybrid automotive powertrain using a 55,000 rpm flywheel to provide bursts of acceleration which the small gas turbine engine could not provide. The flywheel also stored energy through regenerative braking. The flywheel was composed of a titanium hub with a carbon fiber cylinder and gimbal mounted to minimize adverse gyroscopic effects on vehicle handling. The prototype vehicle was successfully road tested in 1997 but was never mass produced. The Parry People Mover is a railcar which is powered by a flywheel. It was trialed on Sundays for 12 months on the Stourbridge Town Branch Line in the West Midlands, England during 2006 and 2007, and will be introduced as a full service by the train operator London Midland in December 2008 once two units have been ordered. Uninterruptible power supply Flywheel power storage systems in current production (2001) have storage capacities comparable to batteries and faster discharge rates. They are mainly used to provide load leveling for large battery systems, such as an uninterruptible power supply for data centers. Flywheel maintenance in general runs about one-half the cost of traditional battery UPS systems. The only maintenance is a basic annual preventive maintenance routine and replacing the bearings every three years, which takes about four hours. Laboratories A long-standing niche market for flywheel power systems are facilities where circuit-breakers and similar devices are tested: even a small household circuit-breaker may be rated to interrupt a current of 10,000 or more amperes, and larger units may have interrupting ratings of 100,000 or 1,000,000 amperes. Obviously the enormous transient loads produced by deliberately forcing such devices to demonstrate their ability to interrupt simulated short circuits would have unacceptable effects on the local grid if these tests were done directly off building power. Typically such a laboratory will have several large motor-generator sets, which can be spun-up to speed over some minutes; then the motor is disconnected before a circuit-breaker is tested. Other similar applications are in tokamak and laser experiments, where very high currents are also used for very brief intervals. Amusement ride The Incredible Hulk roller coaster at Universal's Islands of Adventure features a rapidly accelerating uphill launch as opposed to the typical gravity drop. This is achieved through powerful traction motors that throw the car up the track. To achieve the brief very high current required to accelerate a full coaster train to full speed uphill, the park utilizes several motor generator sets with large flywheels. Without these stored energy units, the park would have to invest in a new substation and risk browning-out the local energy grid every time the ride launches. Pulse power Since FES can store and release energy quickly, they have found a niche providing pulsed power (see compulsator). Motor sports The FIA has re-allowed the use of KERS (see kinetic energy recovery system) as part of its Formula 1 2009 Sporting Regulations F1 technical regulations . Using a continuously variable transmission (CVT), energy is recovered from the drive train during braking and stored in a flywheel. This stored energy is then used during acceleration by altering the ratio of the CVT. - Flybrid Systems In motor sports applications this energy is used to improve acceleration rather than reduce carbon dioxide emissions—although the same technology can be applied to road cars to improve fuel efficiency. - Flybrid Systems, Road Car Application Automobile Club de l'Ouest, the organizer behind the annual 24 Hours of Le Mans event and the Le Mans Series, is currently "studying specific rules for LMP1 which will be equipped with a kinetic energy recovery system." Frequency regulation Beacon Power plans to open an electrical power frequency regulation plant before 2009. Beacon Power Announces Testing of First Megawatt of Flywheel Energy Storage Lower carbon emissions, faster response times and ability to buy power at off-peak hours are among some advantages of using flywheels instead of traditional sources of energy for peaking power plants. Flywheel-based Solutions for Grid Reliability Advantages and disadvantages Flywheels are not affected by temperature changes as are chemical rechargeable batteries, nor do they suffer from memory effect. They are also less potentially damaging to the environment, being made of largely inert or benign materials. Another advantage of flywheels is that by a simple measurement of the rotation speed it is possible to know the exact amount of energy stored. However, use of flywheel accumulators is currently hampered by the danger of explosive shattering of the massive wheel due to overload. One of the primary limits to flywheel design is the tensile strength of the material used for the rotor. Generally speaking, the stronger the disc, the faster it may be spun, and the more energy the system can store. When the tensile strength of a flywheel is exceeded the flywheel will shatter, releasing all of its stored energy at once; this is commonly referred to as "flywheel explosion" since wheel fragments can reach kinetic energy comparable to that of a bullet. Consequently, traditional flywheel systems require strong containment vessels as a safety precaution, which increases the total mass of the device. Fortunately, composite materials tend to disintegrate quickly to red-hot powder once broken, instead of large chunks of high-velocity shrapnel. Still, many customers of modern flywheel energy-storage systems prefer to have them embedded in the ground to halt any material that might escape the containment vessel. When used in vehicles, flywheels also act as gyroscopes, since their angular momentum is typically of a similar order of magnitude as the forces acting on the moving vehicle. This property may be detrimental to the vehicle's handling characteristics while turning. On the other hand, this property could be utilized to keep the car balanced so as to keep it from rolling over during sharp turns. Conversely, the effect can be almost completely removed by mounting the flywheel within an appropriately applied set of gimbals, where the angular momentum is conserved without affecting the vehicle (see Properties of a gyroscope). This doesn't avoid the complication of gimbal lock, and so a compromise between the number of gimbals and the angular freedom is needed. A single gimbal, for instance, could free a car for the 360 degrees necessary for regular driving. However, for instance driving up-hill would require a new gimbal mechanism with a new degree of freedom. Two gimbals would theoretically solve this problem and never lock unless your car rolls (something one carefully placed gimbal would not let the car do). An alternative solution to the problem is to have two joined flywheels spinning synchronously in opposite directions. They would have a total angular momentum of zero and no gyroscopic effect. A problem with this solution is that when the difference between the momentum of each flywheel is anything other than zero the housing of the two flywheels would exhibit torque. The result is two heavy spinning gears. Both wheels must be maintained at the same speed to keep the angular velocity at zero. Strictly speaking, the two flywheels would exert a huge torqueing moment at the central point, trying to bend the axle. However, if the axle were sufficiently strong, no gyroscopic forces would have a net effect on the sealed container, so no torque would be noticed.

7,741 | Oromo_people | The Oromo (Oromo: Oromoo “The Powerful”, Amharic: ኦሮሞ ’Oromo) are an ethnic group found in Ethiopia and to a lesser extent in northern Kenya. Merriam-Webster Inc, Frederick C. Mish, Merriam-Webster's Collegiate Dictionary, (Merriam-Webster: 2003), p.876 They are the largest single ethnic group in Ethiopia, at 34.49% of the population according to the 2007 census, and today number over 25 million. The CSA estimates a population growth of 2.6% between the time the census was conducted and the date of its approval: Their native language is the Oromo language (also called Afaan Oromoo and Oromiffa). History The Oromo are one of the Cushitic-speaking groups of people living in north-eastern and eastern Africa. Cushitic speakers have inhabited parts of north-eastern and eastern Africa for as long as recorded history. Oromos are found predominantly in Ethiopia (99%), but are spread from as far as northern Ethiopia (southern Tigray Region) to northern Kenya, even as far south as Lamu Island. The Oromo represent one of the largest Cushitic-speaking groups inhabiting the Horn of Africa. Their physical features, culture, language and other evidences unequivocally point to the fact that they are indigenous to this part of Africa. Available information indicates that the Oromo existed as a community of people for thousands of years in East Africa (Prouty et al., 1981). Bates (1979) contends that the Oromo "were a very ancient race, the indigenous stock, perhaps, on which most other peoples in this part of eastern Africa have been grafted". While further research is needed to precisely comprehend the origin of Oromo people, it is well known that Oromo people come from a line of pastoralist/nomadic group and/or semi-agriculturalist group. It is likely that they have existed for a longer period of time side by side with their northern Semitic-speaking neighbors. There is a wealth of oral history that describe interactions between the two group dating back as early as the 6th century. . During the 16th century, following the wars between the kingdom of Ethiopia and the neighboring Sultanate of Adal, which resulted in the exhaustion of both states, Oromos moved north into their territories. The Ethiopian monk Bahrey, writing in 1593, attributed the Oromo success to the existence of too many non-fighting classes in the ruling non-Oromo hierarchy, as opposed to the Oromos, whom he described as having a homogeneous warrior class. Bahrey, "History of the Galla" (1593). Translated by C.F. Beckingham and G.W.B. Huntingford in Some Records of Ethiopia 1593-1646 (London: The Hakluyt Society, 1954). This is the earliest known account of the Oromo. Bahrey also explained their spread into northwestern areas such as Arsi, Shewa, Welega, and Gojjam and northeastern areas like Hararghe and Wollo as result of their inhospitable homeland. Marcus, Harold G. A History of Ethiopia. (University of California Press, updated edition: 2002), pp. 37. ISBN 0-520-22479-5 Harold G. Marcus suggests northwest Borena as the original homeland of the Oromo. Marcus, A History of Ethiopia, p. 35. Settled Oromo started to integrate with their Amharic-speaking neighbors at least from the 17th century on. Also, several Oromo chieftains obtained power in government of the monarchy. Particularly Emperor Iyoas I (1730-55), who was half Oromo, favored his mother's Oromo kinsmen and allies, and in his era, the Oromo language was the language of the court in Gondar. By the late 18th century, the power of the central government of Ethiopia had waned, and local governors and kings enjoyed greater autonomy. During this era (which lasted until 1855), known as the Zemene Mesafint, the Oromo dynasty of chiefs of Yejju were the most important continuous line of warlords to dominate the figurehead emperors of Ethiopia. They became sub-kings of Begemder, Enderases (Regents) of the empire, as well as imperial fathers-in-law. Ras Ali I of Yejju achieved this dominance in 1779, and it continued, although contested by other warlords, until the 1855 defeat of Ras Ali II of Yejju by the upstart Kassa Hailu (who in that year became Emperor Tewodros II). Due to the powerlessness of the Emperor of Ethiopia during the Zemene Mesafint, the Yejju Oromo were effectively the rulers of Ethiopia. Other tribes and chiefs of the Oromo people were also prominent, such as lady Menen of Wollo who became Empress in 1800s; Ras Mohammad of Wollo who became Ras Mikael, later Negus of Siyon and father of Emperor Iyasu V; and another lady Menen, of Ambassel, who became Empress consort of Haile Selassie. In order to integrate with the imperial power and family, a large share of the Oromo converted to Ethiopian Orthodox Christianity during these centuries. As one of the last such developments, in late 1800s Emperor Yohannes IV ordered the Oromo tribe of Wollo to convert to Christianity within six months at the threat of losing their property. Such a threat had caused many Wollo Oromos to leave their homeland and migrate further to the South. Their leader was Ras Mohammed who became Ras Mikael and later made an imperial marriage, becoming the father of Emperor Iyasu V. Subgroups The Oromo are divided into two major branches that break down into an assortment of clan families. From west to east, these subgroups are: The Borana which include: The Macha Oromo, living between Didessa River and the Omo River, and south into the Gibe region; The Tulama Oromo, who live in the Oromia Region around Addis Ababa; The Guji Oromo, who are the southern part subgroup of the Oromo, inhabiting neighboring the Garri (Gharri) and Borana Oromo. The Borana Oromo who live in the Borena Zone, which includes Moyale. They also live in Kenya and parts of Somalia. The Gabra Oromo, who live in north Kenya along the Moyale border region The Garri (Gharri) Oromo, who live in north east Kenya and parts of Somalia And countless subdivisions. The Barento/Barentuma which include: The Wallo Oromo, who are the northernmost group, and live predominantly in the Oromia Zone of the Amhara Region, as far north as Lake Ashenge, with whom the Raya Oromo and the Yejju Oromo are often grouped; The Ittu Oromo, who live in the Oromia Region from the Awash River east to a line drawn south of Dire Dawa; The Karayu Oromo, who live along the Awash valley in east Shawa as well as West Hararge The Aniya Oromo, who live south of the Ittu and west of the Erer River; The Afran Qallo which refer to the 4 decedents of Qallo, which are: Ala Oromo, living west of the city of Harar and the Erer River Oborra Oromo, living between Ituu and Ala Oromo Babille Oromo,living east of the Erer River in the Oromia Region Dagaa Oromo (Nole and Jarso): Nole Oromo who live east of Dire Dawa and north of Harar; Jarso who live in the northeastern corner of the of the Oromia Region; The Arsi Oromo, who primarily live in the Arsi Zone of the Oromia Region (which is named for them) as well as the Bale Zone; and The Qallu, who live between the Awash River and Dire Dawa. And countless subdivisions. Society and culture Oromo society was traditionally structured in accordance with gadaa, a social stratification system partially based on an eight-year cycle of age sets. However, over the centuries the age sets grew out-of-alignment with the actual ages of their members, and some time in the 1800s another age set system was instituted. Under gadaa, every eight years the Oromo would hold a popular assembly called the Gumi Gayo, at which laws were established for the following eight years. A democratically elected leader, the Abba Gada, presided over the system for an eight-year term. Gadaa is no longer in wide practice but remains influential. In a short article, Geoffrey W. Arnott described an Oromo rite of passage in which young men run over the backs of bulls surrounded by the village community. Arnott, "Bull Leaping as Inititation Ritual," Liverpool Classical Monthly 18 (1993), pp. 114-116 Bruce Parry filmed the same practice among the Hamar people for his BBC television series "Tribe" transmitted in July 2006. Arnott's interest lay in making a comparison with bull-leaping at Knossos in the Aegean Bronze Age. Religion In the 2007 Ethiopian census in the 88% Oromo region of Oromia, 47,5% were Islamic, 30,5% Orthodox Christians,17,7% Protestants, 3.3% Traditional, and the remaining 1.6% constitute other religious groups. Protestant Christianity is the fastest growing religion inside the Oromo community. In urban areas Oromia Orthodox Christians constitute 51,2% of the population, followed by Muslims 29,9% and Protestants 17%. FDRE States: Basic Information - Oromia, Population (accessed 26 March 2006) But adherence to traditional practices and rituals is still common among many Oromo people regardless of religious background. People of Africa reference Politics History Historically, the Afaan Oromo speaking people used the indigenous Gadaa system of governance that is relatively said to be more democratic than other forms of governance in the region. Many Oromo communities - most notably Gibe Kingdoms, around Jimma - gradually adopted monarchy and other forms of governance in the later centuries of 2nd Millennium. Such changes occurred due to the growing influence of Islam from the east and Orthodox Christianity from the north as well as power struggles between opposing Oromo communities. Both the peaceful and violent competition and integration between Oromos and other neighboring ethnicities of Amhara, Sidama, Somali and others shaped up politics inside the Oromo community historically. Northern Expansion of Oromos, particularly the Arsi, to ethnic Somali and Sidama territories; the Yejju and other Oromo communities to the north, mirrored the southern expansion of Amharas to influence the current ethnic politics in Ethiopia.Oromo and Amhara rule in Ethiopia Also the great Somali expansion from the Ogaden plains west towards the Juba river led to conflicts with the Oromo. [http://dare.uva.nl/document/66264 Somali migration carried nomads fromm the Ogaden plains towards the Juba river] Various commercial and political alliances, often between different ethnicities, occurred during the population movements in the region in the 17th, 18th and 19th centuries. The central Shoa region often saw ethnic Oromo and Amhara alliances against the Amhara dominated Gondar empires while there were several cases of power sharing between Tigre rulers and Yajju Oromo Dynasty as well as the Raya Oromos of Tigray. Yajju Oromo Dynasty Similarly, Afar, Somali and Oromo alliances took place historically, particularly united by religious and territorial ambitions. In some cases, Oromos and Somalis were in competition for good lands and water resources historically. In addition, Eastern Oromos who were converted to Islam ruled over most of Ethiopia together with Afars and Somalis when Horn of African Muslims who were united and led by Ahmad ibn Ibrihim al-Ghazi conquered a majority of Christian Ethiopian highlands. political developments in the pre-colonial horn of Africa Historian Punkhurst stated that before the coming of European powers and the creationn of centralized Ethiopia, the area presently known as Ethiopia, Eritrea and Somalia: Constitutedd a galaxy of states and polities, each moving in its own orbit, but significantly affecting,, and affected by, the other entities in the constellation. Each ruler kept a watchful eye on hiss neighbors but would often exchange gifts and courtesies with them unless actually at war. Dynasticc marriages were made whenever practicable, though these only occasionally crossed barrierss of religion. Commerce, on the other hand, made little distinction between faith, and trade routess linked traditionalist, Christian and Muslim localities. Ethnic and linguistic communities remainedd largely distinct, but there was much cross-fertilization of cultures. This was true not only off the Ethiopian highlands and the Red Sea coastlands, but also further south along the Somali Oromoo frontier where later nineteenth century travelers reported the existence of bilingual trading communities.Horn of Africa history In the first decades of the nineteenth century, three Oromo monarchies, Enarya, Goma and Guma, rose to prominence. Oromo Monarchies In the general view of Oromo people's role in Ethiopia, Ras Gobena is a famous Oromo figure who led the development of modern Ethiopia and the political and miliatary incorporation of more territories into Ethiopian borders. Ras Gobena victory against Gurage militia Donald Levine, Greater Ethiopia, the Evolution of a multicultural society (University of Chicago Press: 1974) Gobana under the authority of Menelik II incorporated several Oromo territories into a centralized Ethiopian state. Some contemporary ethno-nationalist Oromo political groups refer to Gobana in a negative light. Though, before military integration; present day Ethiopia, Eritrea, Somaliland and parts of Somalia were previously and extensively linked commercially by local, long-distance and trans-frontier trade routes. These commercial routes connected Bonga, Jimma, Seqa, Assandabo, Gojjam, Begemder, Maramma, Massawa, Soddo, Shewa, Harar, Zeila and Berbera. POLITICAL DEVELOPMENT IN THE PRE-COLONIAL HORN OF AFRICA Some Oromo writers believe that the Oromo Ras Gobena and the Amhara Menelik II were the first two people in Ethiopia with the concept of national boundary that brought various different ethno-linguistic communities under a politically and militarily centralized rule.Gobana Dache’s Participation in Building Ethiopia "The two most important historical figures who signify the introduction of the concepts of national boundary and sovereignty in Ethiopia are Emperor Menelik II and Ras Gobana Dache, who used guns manufactured in Europe to bring a large swath of Biyas (regions/nations) under a centralized rule." During the last two centuries, Oromos who have not integrated with the Amhara have not had fair political power inside Ethiopia. However, ethnically mixed Ethiopians with Oromo background made up a high percentage of Ethiopian generals and leaders. Union of Amhara and Oromo in royal families The Wollo Oromo (particularly the Raya Oromo and Yejju Oromo) were early Oromo holders of power among the increasingly mixed Ethiopian state. The later north-to-south movement of central power in Ethiopia led to Oromos in Shewa holding power in Ethiopia together with the Shewan Amhara. Oromo in Ethiopian leadership This led to more political and ethnic mixture between Amhara and Oromo in Shewa region, to the degree that northern Amharas labeled Shewan Amharas using the derogatory term "Galla." northern Amhara regarded the Shewans as "Galla" According to a report by HRW, the large presence of assimilated Oromos inside the Ethiopian government did not benefit Oromos who did not assimilate. "In terms of descent, the group that became politically dominant in Shewa - and Subsequently in Ethiopia - was a mixture of Amhara and Oromo; in terms of language, religion and cultural practices, it was Amhara." Background and consequence of Oromos in Ethiopian leadership Nonetheless, in some rare cases Oromo became part of the Ethiopian nobility without losing their identity. Ethiopian Oroo nobility Both ethnically mixed Oromos and those with full Oromo descent held high leadership positions in Ethiopia. Notably Iyasu V was the designated but uncrowned Emperor of Ethiopia (1913 - 1916) while Haile Selassie I was the de jure Emperor of Ethiopia from 1930 to 1974. Both these Ethiopian Emperors are ethnically mixed, with Oromo parents and lineages. During the Zemene Mesafint or "Age of Princes" of Ethiopia, Emperors became figureheads, controlled by warlords like Ras Mikael Sehul of Tigray, and by the Oromo Yejju dynasty, which later led to 17th century Oromo rule of Gondar, changing the language of the court from Amharic to Afaan Oromo. Pankhurst, Richard, The Ethiopian Royal Chronicles, (London:Oxford University Press, 1967), pp. 139–43. 17th century Oromo rule of Gondar By the 1880s, Sahle Selassie, king of Shewa (the later Emperor Menelik II) allied with Ras Gobena's Shewan Oromo militia to expand his kingdom to the South and East, expanding into areas that hadn't been held together since the invasion of Ahmed Gragn. Great Britain and Ethiopia 1897-1910: Competition for Empire Edward C. Keefer, International Journal of African Studies Vol. 6 No. 3 (1973) page 470 Another famous leader of Ethiopia with Oromo descent was Ras Makonnen Woldemikael Gudessa, the governor of Harar who served as the top general in the First Italo–Ethiopian War, playing a key role at the Battle of Adwa. He is the father of Ethiopian Emperor Haile Selassie I. Haile Selassie I, My Life and Ethiopia's Progress: The Autobiography of Emperor Haile Sellassie I, translated from Amharic by Edward Ullendorff. (New York: Frontline Books, 1999), vol. 1 p. 13 Current Most Oromos do not have political unity today due to their historical roles in the Ethiopian state and the region, the spread out movement of different Oromo clans, and the differing religions inside the Oromo nation. Migrations profoundly affected the Oromo unity Accordingly, Oromos played major roles in all three main political movements in Ethiopia (centralist, federalist and secessionist) during the 19th and 20th century. In addition to holding high powers during the centralist government and the monarchy, the Raya Oromos in Tigray played a major role in the revolt inside the Tigray regional state, known as "Weyane" revolt, challenging Emperor Haile Selassie I's rule in the 1940s. Raya Oromos inside the Weyane revolt of Tigray Simultaneously, both federalist and secessionist political forces developed inside the Oromo community. Presently, a number of ethnic based political organizations have been formed to promote the interests of the Oromo. The first was the Mecha and Tulama Self-Help Organization, founded in January 1963, but was disbanded by the government after several increasingly tense confrontations in November, 1966. Bahru Zewde, A History of Modern Ethiopia: 1855-1991, 2nd edition (Oxford: James Currey, 2001), pp. 261f. Later groups include the Oromo Liberation Front (OLF), Oromo Federalist Democratic Movement (OFDM), the United Liberation Forces of Oromia (ULFO), the Islamic Front for the Liberation of Oromia (IFLO), the Oromia Liberation Council (OLC), the Oromo National Congress (ONC, recently changed to OPC) and others. Another group, the Oromo People's Democratic Organization (OPDO), is one of the four parties that form the ruling Ethiopian People's Revolutionary Democratic Front (EPRDF) coalition. However, these Oromo groups do not act in unity: the ONC, for example, was part of the United Ethiopian Democratic Forces coalition that challenged the EPRDF in the Ethiopian general elections of 2005. A number of these groups seek to create an independent Oromo nation, some using armed force. Meanwhile, the ruling OPDO and several opposition political parties in the Ethiopian parliament believe in the unity of the country which has 80 different ethnicities. But most Oromo opposition parties in Ethiopia condemn the economic and political inequalities in the country. Progress has been very slow with the Oromia International Bank just recently established in 2008 though Oromo owned Awash International Bank started early in the 1990s and with the first private Afaan Oromo newspaper in Ethiopia, Jimma Times, also known as Yeroo, recently established. Though the Jimma Times - Yeroo newspaper has faced a lot of harassment and persecution from the Ethiopian government since its beginning. Govt. continues rejecting license for Jimma Times Afaan Oromo newspaper Ethiopia’s "government" attacks Macha-Tulama, Jimma Times media & Oromo opposition party Yeroo newspaper struggles to survive CJFE award nominee CJEE Jimma Times profile Abuse of Oromo media is widespread in Ethiopia and reflective of the general oppression Oromos face in the country. Ethiopia’s Largest Ethnicity Group Deprived of Linguistic and Cultural Sensitive Media Outlets University departments in Ethiopia did not establish curriculum in Afaan Oromo until the late 1990s. Various human rights organizations have publicized the government persecution of Oromos in Ethiopia for decades. In 2008, OFDM opposition party condemned the government's indirect role in the death of hundreds of Oromos in western Ethiopia. OFDM Press Release: The Massacre of May, 2008 Nomenclature The Oromo were formerly called Galla by non-Oromo Ethiopians, and one may encounter this name in older texts, but it is considered a pejorative term. Historically, some people among the northern Amhara community used the label "Galla" derogatorily to label Oromos as well as to label Shewan or southern Amharas who were mostly mixed with Oromo. northern Amhara regarded the Shewans as "Galla" However, when Charles Tutschek, writing in the mid 19th century, researched the Oromo, "his informants, according to their published letters, used Galla as a term of self-reference." Baxter, P.T.W.; Hultin, Jan; Triulzi, Alessandro. Being and Becoming Oromo: Historical and Anthropological Enquiries. (United States:Red Sea Press, Inc.: 1996), p.107. During the years of Italian rule on the Horn of Africa (a colony in Eritrea was set by Rome in 1870 and the whole of Ethiopia was conquered by 1936), Italian geographers accurately mapped the population of their colony and eventually referred to the Oromos preferably as Gallas in all the official maps as well as in a guide-book still available nowadays called "Guida all Africa Orientale Italiana" ("A Guide-Book to Italian Eastern Africa"). The books stated the term Oromo was simply an alternative to Galla. Often in the past, some Oromo communities used Galla to label themselves, as was exemplified by western Oromo leaders who established the "Western Galla Confederation" in the 1930s. Oromos seek recognition for "Western Galla Confederation" ~1936 The name has fallen into disfavor and is now considered to be pejorative, possibly because of a folk etymology for "Galla" (that it came from Qal la or "قال لا," pronounced similar to Gal la, Arabic for "he said no") that implies they refused Muhammad's offer to convert to Islam. In the Somali language, the word gaal means "non-Muslim" or "stranger", a possible reference to the Oromo and their old pagan religion.

7,742 | Demographics_of_Kuwait | This article is about the demographic features of the population of Kuwait, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. Approximately 96% of Kuwait's population is urban. The State of Kuwait's current population is estimated at roughly 3-3.5 million people; counting both locals and foreigners. Roughly 1 million (or nearly one third) of Kuwait's population is local, with 2-2.5 million residents registered as foreigners/non-locals. It is estimated that one in every 3-4 people in Kuwait are of Kuwaiti citizenship. In 2009, more than 580,000 Indian nationals lived in Kuwait making them the single largest expatriate community there. Respect Kuwait's values, culture and tradition, ambassador urges Indians A microcosm of India in the heart of oil-rich Kuwait The rest of the foreign population mainly consists of Egyptians, Bangladeshi, Pakistani, Filipino and Sri Lankan residents. Other foreigners consist of European, North American and Northeast Asian communities - but these are negligible. As for Kuwait's local/citizen population, 60-65% are Arab, 30-35% are Persian, and 5-10% are signified as "others". "Others" mostly includes Africans (Black), East Asian, or European. Non-Arabs (Africans, Persians, East Asians, Europeans, other black or white populations) are generally socially-classed as "Ajam". "Ajam" is a term to describe a non-Arab. Most Ajam are of Persian ancestry, although the Persian population has been declining due to low birth rates, interracial marriages, and sudden influx of Arab populations into the country by naturalization. It is estimated that population percentage of Persians [and other Ajam] might decrease by 5-10% within the next decade. Racially speaking, Kuwaitis are described usually as White or Tan/Black. (Beedh, Sumur, respectively)... However the government does not include this in its database. Civil IDs have no form of racial/ethnic identities. Racism is very rare in Kuwait's society but racism towards other nationalities, especially Indians, Pakistanis and other Asian nationalities, is extremely prevalent and widespread. It is also visible in governmental procedures and services. In addition, religious prejudice exists well within the society. Kuwaitis are predominantly Muslim, though there are a few Christians or atheists. 85% of Kuwait's population is Muslim (Sunni 70%, Shi'a 30%), and 15% is another religion (includes Christian, Hindu, Parsi). CIA - The World Factbook - Kuwait Some other minor Muslim sects do exist in Kuwait's society, but in very small or rare numbers. There are small numbers of Kuwaiti Christians and Jews. International Religious Freedom Report 2005 (US State Department) The 93% literacy rate, one of the Arab world's highest, is due to extensive government support for the education system. Public school education, including Kuwait University, is free, but access is restricted for foreign residents. The government sends qualified students abroad for degrees not offered at Kuwait University. About 1,000 Kuwaitis are currently studying in U.S. universities. Kuwait's official language is Arabic, though only roughly half the country speaks the language primarily. Most foreigners speak Hindi, Urdu, Filipino or Bengali. Most Kuwaitis are also bilingual in that they speak more than one language. E.g. English, Persian, etc. Kuwait has numerous cases of illegal immigration. It is thought that there are at least 10-15,000 illegal immigrants in the country. These immigrants were not deported back to their homelands after their contracts expired. Instead, they remained in Kuwait living off the expense of other immigrants. The population of illegals is increasing by 5,000 individuals each year. It is a hard task deporting or catching the citizens. The last solution would be to naturalize them, but in this case it would affect the demographics of Kuwait significantly. Most illegals are of Indian origin. Other population difficulties encountered in Kuwait involves stateless people who claim residency for Kuwait. Critics argue that these people migrated from Iraq and Saudi Arabia after the economic boom of Kuwait. Since Kuwait's standard of living increased, many have flocked to the country. Most stateless people are Arabs, and count up to 100,000 people. Some are slowly naturalized through different legislative processes, which is ultimately increasing the Arab population of Kuwaiti people. Most obtain nationality by marrying Kuwaiti women. 30-35% of stateless men in adulthood (capable of marital status) have married Kuwait women, and this number is rising. Some encourage the assimilation of stateless and illegal people.

7,743 | Masculism | "Masculism" may also refer to the clinical condition of male physical traits appearing in a woman, see masculinization. Masculinism (also Masculism) is the advocacy of men's rights, and the adherence to or promotion of social theories and moral philosophies regarded as typical of males. The term masculinism was coined as the counterpart of feminism in the early 20th century. The shortened form masculism appears in the 1980s. OED; ; As a political movement, "Masculism" originates with E. Belfort Bax' 1913 The Fraud of Feminism. The term Masculism itself gained currency in the late 20th century, the 1990s or 2000s, in the context of changing gender roles, advocated by authors such as Warren Farrell. Masculist concerns Masculists cite one-sided legislation, selective enforcement, and neglected civil rights as examples of discrimination against men and boys. Examples of questions raised by masculists may include: Violence Masculist concerns focus on societal acceptance of violence harming men paired with the stigma against violence harming women, as well as males being taught or expected to take on violent roles. men forced to risk their lives in male-only conscripted military service. violence against men minimalized or taken less seriously than violence against women depiction of violence against men as humorous, in the media The Myth of Male Power: Why Men Are the Disposable Sex; Warren Farrell, Simon & Schuster, New York, 1993: ISBN 0-671-79349-7 and elsewhere (see Boys are stupid, throw rocks at them!), when women are also violent. assumption of female innocence or sympathy for women, which may result in problems such as disproportionate penalties for men and women for similar crimes, lack of sympathy for male victims in domestic violence cases, and dismissal of female-on-male rape cases. societal failure to address prison rape issues such as prevention (e.g., reducing prison crowding that requires sharing of cells), impunity, and even correctional staff punishing prisoners by confining them with known rapists. http://www.hrw.org/reports/2001/prison/report8.html#_1_50 Attention has been drawn to portrayals of male rape by women, or implied rape, as humorous. Circumcision (characterized as harmless tradition by some, and as male genital mutilation by others) being advocated while female genital mutilation is prohibited. (However, technically, for male genital mutilation to be the same as female genital mutilation, the penis would have to be cut off. Female genital mutilation entails the cutting off of the clitoris, thus ending sexual pleasure and leaving behind a lifetime of possible health problems.) Parenting equality in child custody, such as shared parenting pregnancies carried to term despite agreements ahead of time that they would not be, subjecting men to unwanted parental responsibilities and/or child support expectations (see Dubay v. Wells) The opposite of the above, where a man who feels he wants to have a child has no say in whether his girlfriend/wife aborts their child (see paternal rights and abortion) Equality in adoption rights allowing either unmarried males or females to adopt. Discrimination Legislation that addresses women's needs without considering the corresponding need in men (e.g., Women, Infants, and Children Act; Violence Against Women Act) Biases in the justice system against men, such as higher incarceration rates and longer sentences for men (compared to women) for the same crimes Statutory rape laws enforced more vehemently in instances where the victim is female and/or the perpetrator is male. Double Standard: The Bias Against Male Victims of Sexual Abuse Rape shield laws, which may prevent some men from adequately challenging their accuser Cathy Young, who does not consider herself a "masculinist," argues that in rape cases, "the dogma that "women never lie" means that there is, for all intents and purposes, no presumption of innocence for the defendant" Women may marry at younger ages than men in some U.S. states. ) Men pay higher premiums for auto , life and disability insurance, though discrimination according to race or other criteria is prohibited. In some countries, men have to pay more income tax than their female counterparts. Eg in India the income tax exemption limit for men is Rs 1,50,000 per annum while that for women is Rs 1,80,000 per annum. "Difference in income tax exemption limits for men and women in India" Men not being believed after having been raped by their wife, girlfriend or fiancee; lesser or no penalty for women that rape men Social concerns Increasing suicide rate among young men, four times higher than among young women ; (73% of all suicide deaths are white males in the United States; Suicide in the United States In the United States, more men than women report a history of attempted suicide, with a gender ratio of 3:1) It's usually seen as socially acceptable for a female to try out or follow masculine social norms, whereas if a male does the same for feminine social norms they often attract unwanted attention and are victims of ridicule and insult, with derogatory terms like "pussy" and "faggot" being used. Lack of advocacy for men's rights; little domestic abuse support for men. Bias in health concerns; for example, more advertisements and awareness for breast cancer than prostate cancer, though both cancers kill approximately the same number of people each year. Incarceration for not paying child support, particularly for unwanted children, in contrast to women's right to abort (see Male abortion) Special government agencies for women's affairs with no corresponding agencies for men's affairs Lack of legal ramifications or enforcement for paternity fraud Lack of positive reinforcement and role-models for young boys in the media, while presentation of positive female figures is a large aspect of much of the media. Men are often expected to behave in a macho way. There are also expectations for women to behave in a certain way but not to the extent that it occurs in men. Education Lack of educational aid for boys and men, given that their performance/enrollment at most levels lags behind that of girls and women; some states declaring (de jure or de facto) all-male schools illegal and all-female schools legal. Investing money addressing female underachievement in mathematics or sciences, while ignoring male underachievement in reading. There is concern that some university women's studies departments are more concerned with teaching feminist ideology than equality of gender. The content and emphasis of these courses vary, and some even discuss "masculinities"; but masculists fear that many such courses contribute to animosity towards men. Some universities also carry men's studies courses. Some feminists argue that these are redundant, stating that academia throughout history was predominantly focused on men; however, supporters of these courses note that most subjects throughout history have not dealt with gender directly. Employment Harder physical entrance criteria for men in many occupations, such as the army, police and fire service. Requiring men to be physically stronger than women in these occupations leaves men responsible for a greater share of the physical work, for no more pay. Legal inequality and protections of paternal vs. maternal leave Differences in masculist ideology There is no consensus as to what exactly constitutes "masculism." Some feel the word describes a belief that the male and female genders should be considered complementary and interdependent by necessity. Such expressions of masculism are built around the belief that differentiated gender roles are natural and should be exempt from government interference. Others masculists, such as Warren Farrell, support an ideology of equivalence between the sexes, rather than a belief in unchangeable gender differences. A more encompassing definition might be "a movement to empower males in society, and to redress discrimination against men." Because it is the name of a political and social movement, masculism is sometimes considered synonymous with the men's rights or fathers' rights movements. However, many of the fathers' rights movement make a clear distinction between masculism and their own often quite varied approaches to gender relations. Some masculists state that there is a covert matriarchy and that one of their goals is to overturn it, and elect masculist politicians, whom they would consider more altruistically motivated. Theorists such as David Constantine envision structural changes in taxation or other areas to compensate for what they see as natural differences and expectations between genders. Gender roles in religion are a source of disagreement among masculists: some support a general leadership role for men, while others argue for relative equality between the genders. Liberal masculists such as Warren Farrell tend to favor a secular, gender-neutral stance, whereas conservatives tend to prefer a religious approach, such as represented in The Inevitability of Patriarchy by Steven Goldberg. Conservatives may promote a "New Patriarchy" by countering feminist ideology with their own. Such liberal-conservative dynamics illustrate the diversity of a movement that nonetheless has a unified purpose of promoting men's welfare. Progressive Masculism Progressives masculists view masculism as a complementary movement to feminism, both movements seeking to correct gender discrimination. Progressive masculists do not reject feminism as a movement nor consider feminism a hostile movement and adopt cooperative vision. http://media.www.vanderbiltorbis.com/media/storage/paper983/news/2006/04/03/Masculism/The-Diverse.And.Growing.Mens.Movement-2472232.shtml Warren Farrell, widely seen as a progressive Masculinist stated in The Myth of Male Power that both genders are hampered by the "bisexist" roles of the past: sexism that oppresses both genders. He emphasises the compatibility of both movements: "I use two podiums to debate myself as a feminist and masculist". Fred Hayward, in his speech to the National Congress for Men in 1981, states: "We must not reverse the women's movement; we must accelerate it... Men's liberation is not a backlash, for there is nothing about traditional sex roles that I want to go back to." Farrell suggests that masculism in his conception can assist and aid the women's movement. Likewise, gender egalitarians call for both masculists and feminists who are truly interested in equality to unite under one banner of gender egalitarianism. This philosophy is sympathetic to legitimate grievances of both males and females. The principle of defining masculism on gendereconomy.com is by reverting the definition of feminism and including the same two levels – men are subordinate to women, this condition has to be changed. Masculism carries assumptions about the proper distribution of power and privilege and serves as the bases for a plan of action. Masculism here is defined as a tool to reveal gender inequality. It focuses on the domination of women over men and claims that men are oppressed by hierarchical structures and stereotypes in different levels of society. The scapegoats of masculism are women and domains of female dominance, claimed to be responsible for all the injustice done to men in particular and society in general. Men and women both are found equally responsible for the unsatisfying relations between sexes. Where does the responsibility of women lie? Literary theory Masculist literary theory is a response to feminist literary theory. The term was coined by Rachel Bishop in "The Masculinist Manifesto".

7,744 | Carat_(mass) | The carat is a unit of mass used for measuring gems and pearls (for the use of carat as a measure of purity of gold, see carat (purity)). Currently a carat is defined as exactly 200 mg (0.007055 oz, 3.086 grains). This definition, known as the metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures, and soon afterwards in many countries around the world. The United States adopted the metric carat definition on July 1, 1913, the United Kingdom on 1 April 1914. It is universally used today. The carat is divisible into one hundred points of two milligrams each. For diamonds, a paragon is a flawless stone of at least 100 carats (20 g). The ANSI X.12 EDI standard abbreviation for the carat is CD. Derivation The word came to English from French, derived from the Greek kerátion (κεράτιον), “fruit of the carob”, The literal translation of κεράτιον is little horn, which describes the seed pod. via Arabic qīrāṭ (قيراط) and Italian carato. The Latin word for carat is siliqua. In past centuries, different countries each had their own carat unit, all roughly equivalent to the mass of a carob seed. These units were often used for weighing gold. Carob seeds were used as weights on precision scales because of their reputation for having a uniform weight. However, a 2006 study Turnbull, Lindsay, et al. “Seed size variability: from carob to carats” found carob seeds to have as much variation in their weights as do other seeds (23% vs. 25%), though it seems that it is easier than with other seeds to recognize particularly large or small specimens and remove them. “Did carob seeds allow shady diamond deals?”, New Scientist, page 20, 6 May 2006. Thus, the carob seed was used as a weight not because it was naturally more uniform in weight, but because it could be more easily standardized. Historical definitions in the United Kingdom Board of Trade carat In the United Kingdom, before 1888, the Board of Trade carat was exactly (≈ 3.170) grains; The pre-1888 Board of Trade carat, of which there were exactly per ounce troy, was approximately 205.4094 mg. after 1887, the Board of Trade carat was exactly (≈ 3.168) grains. The post-1887 Board of Trade carat, of which there were exactly 151½ per ounce troy, was approximately 205.3035 mg. Despite it being a non-metric unit, a number of metric countries used this unit for its limited range of application. The Board of Trade carat was divisible into four diamond grains, Unlike the modern carat, the Board of Trade carat was not used for measuring pearls; those were measured with pearl grains. but measurements were typically made in multiples of carat. Pound carat and ounce carat There were also two varieties of refiners’ carats once used in the United Kingdom — the pound carat and the ounce carat. The refiners’ carats were the offspring of the carat as a measure of fineness for gold. The pound troy was divisible into 24 pound carats of 240 grains troy each; the pound carat was divisible into four pound grains of 60 grains troy each; and the pound grain was divisible into four pound quarters of 15 grains troy each. Similarly, the ounce troy was divisible into 24 ounce carats of 20 grains troy each; the ounce carat was divisible into four ounce grains of 5 grains troy each; and the ounce grain was divisible into four ounce quarters of 1¼ grains troy each. Chaffers, William. 1883. Hall Marks on Gold and Silver Plate. 6th edition. London: Bickers & Son. The carat of the Romans and Greeks The solidus (carat) was also a Roman weight unit. There is literary evidence that the weight of 72 coins of the type called solidus was exactly a Roman pound, and that the weight of a solidus was 24 siliquae. The weight of a Roman pound is generally believed to have been 327.45 g or possibly up to 5 g grams less. Therefore the metric equivalent of 1 solidus was approximately 189 mg. The Greeks had a similar unit of the same value. The carat in Byzantine Egypt A carob based weight unit was also used in Egypt in the Byzantine and early Arab periods. In this region, glass weights were used for weighing coins. From these the weight of the Egypt carat has been reconstructed as 196 mg. This is consistent with the average weights of carob seeds in the region. The Syrian and Arabic carat in Mohammad's time According to literary sources, the Arabic carat was only 2% less than the Syrian carat. Based on coins and glass weights their weight was reconstructed as approximately 212 mg. This is consistent with literary information that a solidus weighed slightly less than 22 carats.

7,745 | Blue_Steel_(missile) | Blue Steel was a British air-launched, rocket-propelled nuclear stand-off missile, built to arm the V bomber force. It was the primary British nuclear deterrent weapon until the Royal Navy started operating Polaris missile armed nuclear submarines. Development Avro Blue Steel nuclear missile (front) at the Midland Air Museum Avro Blue Steel missile (side view) at the Midland Air Museum behind the wing of an Avro Vulcan bomber. Blue Steel was the result of a Ministry of Supply memorandum from 5 November 1954 that predicted that by 1960 Soviet air defences would make it prohibitively dangerous for V bombers to attack with nuclear gravity bombs. The answer was for a rocket-powered, supersonic missile capable of carrying a large nuclear (or projected thermonuclear) warhead with a range of at least . This would keep the bombers out of range of Soviet ground-based defences installed around the target area, allowing the warhead to "dash" in at high speed. There would have to be a balance between the size of the warhead (Orange Herald or Green Bamboo as developed by the AWRE) and the need for it to be carried by any of the three V-bomber types in use, and that it should be able to reach Mach 3. The Air Staff issued this requirement for a Stand-off bomb as OR.1132 in September 1954. Gibson Buttler British Secret Projects: Hypersonics, Ramjets and Missiles Midland Publishing 2007 The Ministry of Supply selected Avro out of the British manufacturers though it had no previous experience in working on guided weapons other than some private venture work; Handley Page had suggested a 500 nm missile but the Elliots gyro based guidance system was inaccurate beyond 100 nm. Avro began work proper in 1955, with the assigned Rainbow Code name of "Blue Steel" which it would keep in service. With Elliots working on the guidance system Armstrong Siddeley would develop the liquid fuel engine. Its design period was protracted, with various development problems exacerbated by the fact that designers lacked information on the actual size and weight of the proposed boosted-fission warhead Green Bamboo, or its likely thermonuclear successor derived from the Granite series. The large girth of Blue Steel was determined by the implosion sphere diameter of Green Bamboo. Avro proposed that Blue Steel would evolve over time, subsequent versions increasing speed (to Mach 4.5) and range. The ultimate Blue Steel would be a 900 nm range weapon that could be launched by the supersonic Avro 730 under development. They were told to limit themselves to the specification of OR.1132. The project was delayed by the need to develop the stainless steel fabrication techniques; this would have been gained in building the Avro 730 but that had been cancelled by then. Elliots guidance system was plagued by accuracy problems delaying test flights. As it turned out, neither of these warheads were actually fitted, being superseded by Red Snow, an Anglicised variant of the U.S. W-28 thermonuclear warhead of 1.1 Mt yield. Red Snow was smaller and lighter than the earlier warhead proposals. The missile was fitted with a state-of-the-art inertial navigation unit. This system allowed the missile to strike within 100 metres of its designated target. In addition, the pilots of the Avro Vulcan or Handley Page Victor bombers could tie their systems into those of the missile and make use of the guidance system to help plot their own flight plan, since the unit in the missile was more advanced than that in the aircraft. Blue Steel emerged as a pilotless, winged aircraft roughly the size of the experimental Saunders-Roe SR.53 interceptor, with clipped delta wings and small canard foreplanes. It was powered by a two-chamber Armstrong Siddeley Stentor Mark 101 rocket engine, burning a combination of hydrogen peroxide and kerosene. The fuel was a considerable operational problem, because fuelling the missile before launch took nearly half an hour, and was quite hazardous. On launch the rocket engine's first chamber developing thrust would power the missile along a predetermined course to the target at around Mach 1.5. Once close to the target, the second chamber of the engine (6,000 lb) would accelerate the missile to Mach 3. Over the target the engine would cut out and the missile would free-fall before detonating its warhead as an Air burst. To speed the trials at Woomera, the test rounds were flown there by Victors and Vulcans in Operation Blue Ranger. The trials began in 1960 about the time the original requirement expected the weapon to be in service. Blue Steel finally entered service in February 1963, being carried by Vulcans and Victors, although its limitations were already apparent. The short range of the missile meant that the V bombers were still vulnerable to enemy SAMs. A replacement for Blue Steel, the Mark 2, was planned with increased range and a ramjet engine, but was cancelled in 1960 to minimise delays to the Mk.1. The UK sought to acquire the much longer-ranged United States Air Force AGM-48 Skybolt air-launched ballistic missile, and was greatly frustrated when that weapon was cancelled in late 1962. With no effective long-range weapon the original Blue Steel served on after a crash programme of minor modifications to permit a low-level launch at , even though its usefulness in a hot war was likely limited. A stop-gap weapon (WE.177B) was quickly produced to extend the life of the V-bomber force in the strategic role until the Polaris missile was deployed. This WE.177 laydown weapon supplemented the remaining modified Blue Steel missiles using a low-level penetration followed by a pop-up manoeuvre to release the weapon at Forty-eight live operational rounds were deployed on 48 Vulcan and Victor bombers plus a further five live rounds as operational spares. An additional four non-nuclear rounds were produced for various RAF requirements, and there were 16 other unspecified training rounds. Blue Steel was officially retired on 31 December 1970, with the United Kingdom's strategic nuclear capacity passing to the submarine fleet.

7,746 | French_language | French (français, ) is a Romance language spoken around the world by around 90 million people as first language, by 190 million as second language, and by about another 200 million people as an acquired foreign language, with significant speakers in 54 countries. Most native speakers of the language live in France, where the language originated. The rest live essentially in Canada, Belgium, Switzerland, Francophone Africa, Luxembourg, and Monaco. Most second language speakers of French live in Francophone Africa, arguably exceeding the number of native speakers. La Francophonie dans le monde 2006–2007 published by the Organisation internationale de la Francophonie. Nathan, Paris, 2007 The Democratic Republic of the Congo is however the Francophone country with the largest population. French is a descendant of the Latin language of the Roman Empire, as are national languages such as Portuguese, Spanish, Italian and Romanian, and minority languages ranging from Catalan and Occitan to Neapolitan and many more. Its development was also influenced by the native Celtic languages of Roman Gaul and by the Germanic language of the post-Roman Frankish invaders. It is an official language in 29 countries, most of which form what is called, in French, La Francophonie, the community of French-speaking nations. It is an official language of all United Nations agencies and a large number of international organizations. According to the European Union, 129 million (26% of the 497,198,740) people in 27 member states speak French, of which 65 million (12%) are native speakers and 69 million (14%) claim to speak it either as a second or foreign language, which makes it the third most spoken second language in the Union, after English and German. In addition, prior to the early 20th century, French served as the preeminent language of diplomacy among European and colonial powers as well as a lingua franca among the educated classes of Europe. Geographic distribution Europe French is joint second as a second language along with German, both being at 14%, English is first with 38% http://ec.europa.eu/education/languages/pdf/doc3275_en.pdf Legal status in France According to the Constitution of France, French has been the official language since 1992 Loi constitutionnelle 1992 — (although previous legal texts have made it official since 1539, see ordinance of Villers-Cotterêts). France mandates the use of French in official government publications, public education outside of specific cases (though these dispositions are often ignored) and legal contracts; advertisements must bear a translation of foreign words. In addition to French, there are also a variety of regional languages and dialects. France has signed the European Charter for Regional Languages, but has not ratified it since that would go against the 1958 Constitution. Switzerland French is one of the four official languages of Switzerland (along with German, Italian, and Romansh) and is spoken in the part of Switzerland called Romandie. French is the native language of about 20% of the Swiss population. Belgium Bilingual signs in Brussels. In Belgium, French is the official language of Wallonia (excluding the East Cantons, which are German-speaking) and one of the two official languages —along with Dutch— of the Brussels-Capital Region where it is spoken by the majority of the population, though often not as their primary language. — The linguistic situation in Belgium (and in particular various estimations of the population speaking French and Dutch in Brussels) is discussed in detail. French and German are not official languages nor recognized minority languages in the Flemish Region, although along borders with the Walloon and Brussels-Capital regions, there are a dozen municipalities with language facilities for French-speakers. A mirror situation exists for the Walloon Region with respect to the Dutch and German languages. In total, native French-speakers make up about 40% of the country's population, while the remaining 60% speak Dutch. Of the latter, 59% claim to speak French as a second language. French is thus known by an estimated 75% of all Belgians, either as a mother tongue, as second, or as third language. 40%+60%*59%=75.4% Malta Maltese is a Semitic language C.F. & F.M. Voegelin. 1977.

Monaco and Andorra Although Monégasque is the national language of the Principality of Monaco, French is the only official language, and French nationals make up some 47% of the population. Catalan is the only official language of Andorra; however, French is commonly used due to the proximity to France. French nationals make up 7% of the population. Knowledge of French in the European Union and candidate countries Source: , data for EU25, published before 2007 enlargement. Italy French is also an official language, along with Italian, in the province of Aosta Valley, Italy. In addition, a number of Franco-Provençal dialects are spoken in the province, although they do not have official recognition. http://www.regione.vda.it/turismo/la_tradizione/lingue_f.asp Luxembourg French is one of three official languages of the Grand Duchy of Luxembourg, alongside German and Luxembourgish, the natively-spoken language of Luxembourg. Luxembourg's education system is trilingual: the first years of primary school are in Luxembourgish, before changing to German; while in secondary school, the language of instruction changes to French. The United Kingdom and the Channel Islands French is an official language in Jersey and Guernsey, the two bailiwicks collectively referred to as the Channel Islands, although they are separate entities. Both use French to some degree, mostly in an administrative capacity. Jersey Legal French is the standardized variety used in Jersey. However, Norman is the historical vernacular langue d'Oïl of the islands. The majority of words of the English Language (originating in Great Britain) are of French root or origin. This is due to the Norman Invasion which made French the language of administration and was spoken by the aristocracy and upper classes (while the peasants and lower classes spoke a Anglo-Saxon Language). French is a large minority language and immigrant language in the UK with over 1 million speakers as a first language. It is also the most popular foreign language with just under a quater of the British population being able to speak french proficiently. Americas Canada Bilingual (English/French) stop sign on Parliament Hill in Ottawa, an example of bilingualism at the federal level in Canada. French is the second most common language in Canada, after English, and both are official languages at the federal level. French is the sole official language in the province of Quebec, being the mother tongue for some 7 million people. New Brunswick, where about a third of the population is francophone, is the only officially bilingual province. Portions of Ontario, Nova Scotia and Manitoba have sizeable French minorities, but its prescription as an official language in those jurisdictions and the level of francophone services varies. Haiti French is an official language of Haiti, although it is mostly spoken by the upper class, while Haitian Creole (a French-based creole language) is more widely spoken as a mother tongue. French overseas territories French is also the official language in France's overseas territories of French Guiana, Guadeloupe, Martinique, Saint Barthélemy, St. Martin and Saint-Pierre and Miquelon The United States French language spread in the United States. Counties marked in yellow are those where 6–12% of the population speak French at home; brown, 12–18%; red, over 18%. French-based creole languages are not included. Although it has no official recognition on a federal level, French is the third National Virtual Translation Center — Languages Spoken in the U.S. U.S. Census Bureau, Census 2000 Summary File 3 — Language Spoken at Home: 2000 most-spoken language in the United States, after English and Spanish, and the second most-spoken in the states of Louisiana, Maine, Vermont and New Hampshire. Louisiana is home to many distinct dialects, Cajun French has the largest number of speakers. According to the 2000 US Census, there are over 194,000 people in Louisiana who speak French at home, the most of any state if excluding Creole French. Africa Supermarket sign in French in Dakar, Senegal. A majority of the world's French-speaking population lives in Africa. According to the 2007 report by the Organisation internationale de la Francophonie, an estimated 115 million African people spread across 31 francophone African countries can speak French either as a first or second language. French is mostly a second language in Africa, but in some areas it has become a first language, such as in the region of Abidjan, Côte d'Ivoire Le français à Abidjan : Pour une approche syntaxique du non-standard by Katja Ploog, CNRS Editions, Paris, 2002 and in Libreville, Gabon. "De plus, le français est également devenu la langue maternelle de plus de 30 % des Librevillois et il est de plus en plus perçu comme une langue gabonaise." It is not possible to speak of a single form of African French, but rather of diverse forms of African French which have developed due to the contact with many indigenous African languages. "En Afrique, il est impossible de parler d'une forme unique du français mais..." In the territories of the Indian Ocean, the French language is often spoken alongside French-derived creole languages, the major exception being Madagascar. There, a Malayo-Polynesian language (Malagasy) is spoken alongside French. The French language has also met with competition from English, since English has been the official language in Mauritius and the Seychelles for a while and has recently become an official language of Madagascar. Sub-Saharan Africa is the region where the French language is most likely to expand, due to the expansion of education and rapid demographic growth. "Furthermore, the demographic growth of Southern hemisphere countries leads us to anticipate a new increase in the overall number of French-speakers." It is also where the language has evolved the most in recent years. http://www.cecif.com/?page=la_francophonie "Le français, langue en évolution Dans beaucoup de pays francophones, surtout sur le continent africain, une proportion importante de la population ne parle pas couramment le français (même s'il est souvent la langue officielle du pays). Ce qui signifie qu'au fur et à mesure que les nouvelles générations vont à l'école, le nombre de francophones augmente : on estime qu'en 2015, ceux-ci seront deux fois plus nombreux qu'aujourd'hui." c) Le sabir franco-africain: Some vernacular forms of French in Africa can be difficult to understand for French speakers from other countries République centrafricaine: (One example of a variety of African French that is difficult to understand for European French speakers). , but written forms of the language are very closely related to those of the rest of the French-speaking world. French is an official language in many African countries, most of them former French or Belgian colonies: Benin Burkina Faso Burundi Cameroon Central African Republic Chad Comoros Congo (Brazzaville) Côte d'Ivoire Democratic Republic of the Congo Djibouti Equatorial Guinea (former colony of Spain) Gabon Guinea Madagascar Mali Niger Rwanda Senegal Seychelles Togo In addition, French is an administrative language and commonly used, though not on an official basis, in Mauritius and in the Maghreb states: Algeria Mauritania Morocco Tunisia In Algeria, various reforms have been implemented in recent decades to improve the status of Arabic relative to French, especially in education. While the predominant European language in Egypt is English, French is considered to be a more sophisticated language by some elements of the Egyptian upper and upper-middle classes; for this reason, a typical educated Egyptian will learn French in addition to English at some point in his or her education. The perception of sophistication may be related to the use of French as the royal court language of Egypt during the nineteenth century. Egypt participates in La Francophonie. French is also the official language of Mayotte and Réunion, two overseas territories of France located in the Indian Ocean, as well as an administrative and educational language in Mauritius, along with English. Asia Lebanon A Lebanese "mille livres" (thousand-pound) bank note French was the official language in Lebanon, along with Arabic, until 1943, when the country declared independence from France. French is still considered an official language by the Lebanese people and is used on bank notes (along with Arabic) and on official buildings. French is widely used by the Lebanese, especially for administrative purposes, and is taught in many schools as a primary language along with Arabic. Syria Like Lebanon, French was official in Syria until 1943. But in contrast to Lebanon, the language is not official, but still spoken by educated group, both elites and middle-class. Southeast Asia French is an administrative language in Laos and Cambodia, although its influence has waned in recent years. French Declines in Indochina, as English Booms, International Herald Tribune, 16 October 1993: "In both Cambodia and Laos, French remains the official second language of government." In colonial Vietnam, the elites spoke French, and many who worked for the French spoke a French creole known as "Tây Bồi" (now extinct). The language was also spoken by the elite in the leased territory Guangzhouwan in southern China. In Burma, French is gaining popularity amongst university students and the tourism sector, as the country slowly opens up. French is not offered at the basic education level, but the University of Foreign Languages in Yangon offers a B.A. in French, and Alliance Française has active centres in Rangoon and Mandalay. The Francophone community is estimated to number from 25,000 to 50,000+. India French has de-jure official status in the Indian Union Territory of Pondicherry, along with the regional languages Tamil, Telugu. Some students of Tamil Nadu opt for French as their second or third language (usually behind English and Tamil). French is commonly taught as a third language in secondary schools in most cities of Maharashtra, including Mumbai, as part of the preparation for secondary school (X-SSC) and higher secondary school (XII-HSC) certificate examinations. Certain high-profile schools affiliated with the CBSE in the NCR offer French as an option as early as grade 4. In grade 9, students are asked to drop either French or Hindi, which is their native language. Oceania French is a second official language of the Pacific Island nation of Vanuatu, along with France's territories of French Polynesia, Wallis & Futuna and New Caledonia.

Voiced stops (i.e. ) are typically produced fully-voiced throughout. Voiceless stops (i.e. ) are unaspirated. Nasals: The velar nasal occurs only in final position in borrowed (usually English) words: parking, camping, swing. The palatal nasal can occur in word initial position (e.g. gnon), but it is most frequently found in intervocalic, onset position or word-finally (e.g. montagne). Fricatives: French has three pairs of homorganic fricatives distinguished by voicing, i.e. labiodental , dental , and palato-alveolar . Notice that are dental, like the plosives , and the nasal . French has one rhotic whose pronunciation varies considerably among speakers and phonetic contexts. In general it is described as a voiced uvular fricative as in roue, "wheel" . Vowels are often lengthened before this segment. It can be reduced to an approximant, particularly in final position (e.g. fort) or reduced to zero in some word-final positions. For other speakers, a uvular trill is also fairly common, and an apical trill occurs in some dialects. Lateral and central approximants: The lateral approximant is unvelarised in both onset (lire) and coda position (il). In the onset, the central approximants , , and each correspond to a high vowel, , , and respectively. There are a few minimal pairs where the approximant and corresponding vowel contrast, but there are also many cases where they are in free variation. Contrasts between and occur in final position as in paye, "pay", vs. pays, "country". French pronunciation follows strict rules based on spelling, but French spelling is often based more on history than phonology. The rules for pronunciation vary between dialects, but the standard rules are: final consonants: Final single consonants, in particular s, x, z, t, d, n and m, are normally silent. (The final letters c, r, f and l, however, are normally pronounced.) When the following word begins with a vowel, however, a silent consonant may once again be pronounced, to provide a liaison or "link" between the two words. Some liaisons are mandatory, for example the s in les amants or vous avez; some are optional, depending on dialect and register, for example the first s in deux cents euros or euros irlandais; and some are forbidden, for example the s in beaucoup d'hommes aiment. The t of et is never pronounced and the silent final consonant of a noun is only pronounced in the plural and in set phrases like pied-à-terre. Doubling a final n and adding a silent e at the end of a word (e.g. chien → chienne) makes it clearly pronounced. Doubling a final l and adding a silent e (e.g. gentil → gentille) adds a [j] sound if the l is preceded by the letter i. elision or vowel dropping: Some monosyllabic function words ending in a or e, such as je and que, drop their final vowel when placed before a word that begins with a vowel sound (thus avoiding a hiatus). The missing vowel is replaced by an apostrophe. (e.g. je ai is instead pronounced and spelled → j'ai). This gives, for example, the same pronunciation for l'homme qu'il a vu ("the man whom he saw") and l'homme qui l'a vu ("the man who saw him"). However, for Belgian French the sentences are pronounced differently, in the first sentence "qu'il" is formed as one syllable while in the second sentence, it is pronounced as two syllables. Orthography Nasal: n and m. When n or m follows a vowel or diphthong, the n or m becomes silent and causes the preceding vowel to become nasalized (i.e. pronounced with the soft palate extended downward so as to allow part of the air to leave through the nostrils). Exceptions are when the n or m is doubled, or immediately followed by a vowel. The prefixes en- and em- are always nasalized. The rules get more complex than this but may vary between dialects. Digraphs: French not only uses diacritics to specify its large range of vowel sounds and diphthongs, but also specific combinations of vowels, sometimes with following consonants, to show which sound is intended. Gemination: Within words, double consonants are generally not pronounced as geminates in modern French (but geminates can be heard in the cinema or TV news from as recently as the 1970s, and in very refined elocution they may still occur). For example, illusion is pronounced and not . But gemination does occur between words. For example, une info ("a news item" or "a piece of information") is pronounced , whereas une nympho ("a nymphomaniac") is pronounced . Accents are used sometimes for pronunciation, sometimes to distinguish similar words, and sometimes for etymology alone. Accents that affect pronunciation The acute accent (l'accent aigu), é (e.g. école—school), means that the vowel is pronounced instead of the default . The grave accent (l'accent grave), è (e.g. élève—pupil) means that the vowel is pronounced instead of the default . The circumflex (l'accent circonflexe) ê (e.g. forêt—forest) shows that an e is pronounced and that an ô is pronounced . In standard French, it also signifies a pronunciation of for the letter â, but this differentiation is disappearing. In the late 19th century, the circumflex was used in place of s after a vowel, where that letter s was not to be pronounced. Thus, forest became forêt and hospital became hôpital. The diaeresis (le tréma) (e.g. naïf—foolish, Noël—Christmas) as in English, specifies that this vowel is pronounced separately from the preceding one, not combined, and is not a schwa. The cedilla (la cédille) ç (e.g. garçon—boy) means that the letter ç is pronounced in front of the hard vowels a, o and u (c is otherwise before a hard vowel). C is always pronounced in front of the soft vowels e, i, and y, thus ç is never found in front of soft vowels. Accents with no pronunciation effect The circumflex does not affect the pronunciation of the letters i or u, and in most dialects, a as well. It usually indicates that an s came after it long ago, as in île (island, compare with English isle). All other accents are used only to distinguish similar words, as in the case of distinguishing the adverbs là and où ("there", "where") from the article la ("the" fem. sing.) and the conjunction ou ("or") respectively. Writing system French is written using the 26 letters of the Latin alphabet, plus five diacritics (the circumflex accent, acute accent, grave accent, diaeresis, and cedilla) and the two ligatures (œ) and (æ). French spelling, like English spelling, tends to preserve obsolete pronunciation rules. This is mainly due to extreme phonetic changes since the Old French period, without a corresponding change in spelling. Moreover, some conscious changes were made to restore Latin orthography: Old French doit > French doigt "finger" (Latin digitus) Old French pie > French pied "foot" (Latin pes (stem: ped-)) As a result, it is difficult to predict the spelling on the basis of the sound alone. Final consonants are generally silent, except when the following word begins with a vowel. For example, all of these words end in a vowel sound: pied, aller, les, , beaux. The same words followed by a vowel, however, may sound the consonants, as they do in these examples: beaux-arts, les amis, pied-à-terre. On the other hand, a given spelling will almost always lead to a predictable sound, and the Académie française works hard to enforce and update this correspondence. In particular, a given vowel combination or diacritic predictably leads to one phoneme. The diacritics have phonetic, semantic, and etymological significance. acute accent (é): Over an e, indicates the sound of a short ai in English, with no diphthong. An é in modern French is often used where a combination of e and a consonant, usually s, would have been used formerly: écouter < escouter. This type of accent mark is called accent aigu in French. grave accent (à, è, ù): Over a or u, used only to distinguish homophones: à ("to") vs. a ("has"), ou ("or") vs. où ("where"). Over an e, indicates the sound . circumflex (â, ê, î, ô, û): Over an a, e or o, indicates the sound , or , respectively (the distinction a vs. â tends to disappear in many dialects). Most often indicates the historical deletion of an adjacent letter (usually an s or a vowel): château < castel, fête < feste, sûr < seur, dîner < disner. It has also come to be used to distinguish homophones: du ("of the") vs. dû (past participle of devoir "to have to do something (pertaining to an act)"; note that dû is in fact written thus because of a dropped e: deu). (See Use of the circumflex in French) diaeresis or tréma (ë, ï, ü, ÿ): Indicates that a vowel is to be pronounced separately from the preceding one: naïve, Noël. A diaeresis on y only occurs in some proper names and in modern editions of old French texts. Some proper names in which ÿ appears include Aÿ (commune in canton de la Marne formerly Aÿ-Champagne), Rue des Cloÿs (alley in the 18th arrondisement of Paris), Croÿ (family name and hotel on the Boulevard Raspail, Paris), Château du Feÿ (near Joigny), Ghÿs (name of Flemish origin spelt Ghijs where ij in handwriting looked like ÿ to French clerks), l'Haÿ-les-Roses (commune between Paris and Orly airport), Pierre Louÿs (author), Moÿ (place in commune de l'Aisne and family name), and Le Blanc de Nicolaÿ (an insurance company in eastern France). The diaresis on u appears only in the biblical proper names Archélaüs, Capharnaüm, Emmaüs, Ésaü and Saül. Nevertheless, since the 1990 orthographic rectifications, the diaeresis in words containing guë (such as aiguë or ciguë) may be moved onto the u: aigüe, cigüe. umlaut: Words coming from German retain the old Umlaut (ä, ö and ü) if applicable but use French pronunciation, such as Kärcher (trade mark of a pressure washer). cedilla (ç): Indicates that an etymological c is pronounced when it would otherwise be pronounced /k/. Thus je lance "I throw" (with c = before e), je lançais "I was throwing" (c would be pronounced before a without the cedilla). The c cedilla (ç) softens the hard /k/ sound to /s/ before the vowels a, o or u, for example ça /sa/. C cedilla is never used before the vowels e or i since these two vowels always produce a soft /s/ sound (ce, ci). There are two ligatures, which have various origins: The ligature œ is a mandatory contraction of oe in certain words. Some of these are native French words, with the pronunciation or , e.g. sœur "sister" , œuvre "work (of art)" . Note that it usually appears in the combination œu; œil is an exception. Many of these words were originally written with the digraph eu; the o in the ligature represents a sometimes artificial attempt to imitate the Latin spelling: Latin bovem > Old French buef/beuf > Modern French bœuf. Œ is also used in words of Greek origin, as the Latin rendering of the Greek diphthong οι, e.g. cœlacanthe "coelacanth". These words used to be pronounced with the vowel , but in recent years a spelling pronunciation with has taken hold, e.g. œsophage or . The pronunciation with is often seen to be more correct. The ligature œ is not used in some occurrences of the letter combination oe, for example, when o is part of a prefix (coexister). The ligature æ is rare and appears in some words of Latin and Greek origin like ægosome, ægyrine, æschne, cæcum, nævus or uræus. La ligature æ The vowel quality is identical to é . French writing, as with any language, is affected by the spoken language. In Old French, the plural for animal was animals. Common speakers pronounced a u before a word ending in l as the plural. This resulted in animauls. As the French language evolved this vanished and the form animaux (aux pronounced ) was admitted. The same is true for cheval pluralized as chevaux and many others. Also castel pl. castels became château pl. châteaux. Grammar French grammar shares several notable features with most other Romance languages, including: the loss of Latin's declensions only two grammatical genders the development of grammatical articles from Latin demonstratives new tenses formed from auxiliaries French word order is Subject Verb Object, except when the object is a pronoun, in which case the word order is Subject Object Verb. Some rare archaisms allow for different word orders. Vocabulary The majority of French words derive from Vulgar Latin or were constructed from Latin or Greek roots. There are often pairs of words, one form being "popular" (noun) and the other one "savant" (adjective), both originating from Latin. Example: brother: frère / fraternel < from Latin frater finger: doigt / digital < from Latin digitus faith: foi / fidèle < from Latin fides cold: froid / frigide < from Latin frigidus eye: œil / oculaire < from Latin oculus In some examples there is a common word from Vulgar Latin and a more savant word borrowed directly from Medieval Latin or even Ancient Greek. Cheval—Concours équestre—Hippodrome The French words which have developed from Latin are usually less recognisable than Italian words of Latin origin because as French evolved from Vulgar Latin, the unstressed final syllable of many words was dropped or elided into the following word. It is estimated that 12% (4,200) of common French words found in a typical dictionary such as the Petit Larousse or Micro-Robert Plus (35,000 words) are of foreign origin. About 25% (1,054) of these foreign words come from English and are fairly recent borrowings. The others are some 707 words from Italian, 550 from ancient Germanic languages, 481 from ancient Gallo-Romance languages, 215 from Arabic, 164 from German, 160 from Celtic languages, 159 from Spanish, 153 from Dutch, 112 from Persian and Sanskrit, 101 from Native American languages, 89 from other Asian languages, 56 from other Afro-Asiatic languages, 55 from Slavic languages and Baltic languages, 10 for Basque and 144 — about three percent — from other languages. Walter & Walter 1998 Numerals The French counting system is partially vigesimal: twenty () is used as a base number in the names of numbers from 60–99. The French word for eighty, for example, is , which literally means "four twenties", and (literally "sixty-fifteen") means 75. This reform arose after the French Revolution to unify the different counting system (mostly vigesimal near the coast, due to Celtic (via Breton) and Viking influence). This system is comparable to the archaic English use of score, as in "fourscore and seven" (87), or "threescore and ten" (70). Belgian French and Swiss French are different in this respect. In Belgium and Switzerland 70 and 90 are and . In Switzerland, depending on the local dialect, 80 can be (Geneva, Neuchâtel, Jura) or (Vaud, Valais, Fribourg). Octante had been used in Switzerland in the past, but is now considered archaic. . See also the English Wikipedia article on Welsh language, especially the section "Counting system" and its note on the influence of Celtic in the French counting system. In Belgium, however, quatre-vingts is universally used. It should also be noted that French uses a period (also called a full stop) or a space to separate thousands where English uses a comma or (more recently) a space. The comma is used in French numbers as a decimal point: 2,5 = deux virgule cinq. Cardinal numbers in French from 1 to 20 are as follows: One: un Two: deux Three: trois Four: quatre Five: cinq Six: six Seven: sept Eight: huit Nine: neuf Ten: dix Eleven: onze Twelve: douze Thirteen: treize Fourteen: quatorze Fifteen: quinze Sixteen: seize Seventeen: dix-sept Eighteen: dix-huit Nineteen: dix-neuf Twenty: vingt Examples The "Canadian" audio samples here are not necessarily from speakers of Quebec French, which has distinct regional pronunciations of certain words.references needed English French IPA pronunciation (Canadian accent) IPA pronunciation (French accent)French Français English Anglais Yes Oui or "Si" No Non Hello!

7,747 | Mind | Mind () refers to the aspects of intellect and consciousness manifested as combinations of thought, perception, memory, emotion, will and imagination, including all of the brain's conscious and unconscious cognitive processes. "Mind" is often used to refer especially to the thought processes of reason. Subjectively, mind manifests itself as a stream of consciousness. There are many theories of the mind and its function. The earliest recorded works on the mind are by Zarathushtra, the Buddha, Plato, Aristotle, Adi Shankara and other ancient Greek, Indian and Islamic philosophers. Pre-scientific theories, based in theology, concentrated on the relationship between the mind and the soul, the supernatural, divine or god-given essence of the person. Modern theories, based on scientific understanding of the brain, theorize that the mind is a product of the brain and has both conscious and unconscious aspects. The question of which attributes make up the mind is also much debated. Some argue that only the "higher" intellectual functions constitute mind: particularly reason and memory. In this view the emotions - love, hate, fear, joy - are more "primitive" or subjective in nature and should be seen as different from the mind. Others argue that the rational and the emotional sides of the human person cannot be separated, that they are of the same nature and origin, and that they should all be considered as part of the individual mind. In popular usage mind is frequently synonymous with thought. It is that private conversation with ourselves that we carry on "inside our heads." Thus we "make up our minds," "change our minds" or are "of two minds" about something. One of the key attributes of the mind in this sense is that it is a private sphere to which no one but the owner has access. No-one else can "know our mind." They can only interpret what we consciously or unconsciously communicate. Aspects of mind Mental faculties Thought is a mental process which allows an individual to model the world, and so to deal with it effectively according to their goals, plans, ends and desires. Words referring to similar concepts and processes include cognition, idea, and imagination. Thinking involves the cerebral manipulation of information, as when we form concepts, engage in problem solving, reasoning and making decisions. Thinking is a higher cognitive function and the analysis of thinking processes is part of cognitive psychology. Memory is an organism's ability to store, retain, and subsequently recall information. Although traditional studies of memory began in the realms of philosophy, the late nineteenth and early twentieth century put memory within the paradigms of cognitive psychology. In recent decades, it has become one of the principal pillars of a new branch of science called cognitive neuroscience, a marriage between cognitive psychology and neuroscience. Imagination is accepted as the innate ability and process to invent partial or complete personal realms the mind derives from sense perceptions of the shared world. The term is technically used in psychology for the process of reviving in the mind percepts of objects formerly given in sense perception. Since this use of the term conflicts with that of ordinary language, some psychologists have preferred to describe this process as "imaging" or "imagery" or to speak of it as "reproductive" as opposed to "productive" or "constructive" imagination. Imagined images are seen with the "mind's eye". One hypothesis for the evolution of human imagination is that it allowed conscious beings to solve problems (and hence increase an individual's fitness) by use of mental simulation. Consciousness in mammals (this includes humans) is an aspect of the mind generally thought to comprise qualities such as subjectivity, sentience, and the ability to perceive the relationship between oneself and one's environment. It is a subject of much research in philosophy of mind, psychology, neuroscience, and cognitive science. Some philosophers divide consciousness into phenomenal consciousness, which is subjective experience itself, and access consciousness, which refers to the global availability of information to processing systems in the brain.<ref name="Bl"> Ned Block: On a Confusion about a Function of Consciousness" in: The Behavioral and Brain Sciences, 1995.</ref> Phenomenal consciousness has many different experienced qualities, often referred to as qualia. Phenomenal consciousness is usually consciousness of something or about something, a property known as intentionality in philosophy of mind. Philosophy of mind Philosophy of mind is the branch of philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness and their relationship to the physical body. The mind-body problem, i.e. the relationship of the mind to the body, is commonly seen as the central issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body. Dualism and monism are the two major schools of thought that attempt to resolve the mind-body problem. Dualism is the position that mind and body are in some way separate from each other. It can be traced back to Plato, Aristotle Robinson, H. (1983): ‘Aristotelian dualism’, Oxford Studies in Ancient Philosophy 1, 123-44. Nussbaum, M. C. (1984): ‘Aristotelian dualism’, Oxford Studies in Ancient Philosophy, 2, 197-207. Nussbaum, M. C. and Rorty, A. O. (1992): Essays on Aristotle's De Anima, Clarendon Press, Oxford. and the Samkhya and Yoga schools of Hindu philosophy, but it was most precisely formulated by René Descartes in the 17th century. Substance dualists argue that the mind is an independently existing substance, whereas Property dualists maintain that the mind is a group of independent properties that emerge from and cannot be reduced to the brain, but that it is not a distinct substance. Hart, W.D. (1996) "Dualism", in Samuel Guttenplan (org) A Companion to the Philosophy of Mind, Blackwell, Oxford, 265-7. Monism is the position that mind and body are not physiologically and ontologically distinct kinds of entities. This view was first advocated in Western Philosophy by Parmenides in the 5th Century BC and was later espoused by the 17th Century rationalist Baruch Spinoza. Spinoza, Baruch (1670) Tractatus Theologico-Politicus (A Theologico-Political Treatise). According to Spinoza's dual-aspect theory, mind and body are two aspects of an underlying reality which he variously described as "Nature" or "God". Physicalists argue that only the entities postulated by physical theory exist, and that the mind will eventually be explained in terms of these entities as physical theory continues to evolve. Idealists maintain that the mind is all that exists and that the external world is either mental itself, or an illusion created by the mind. Neutral monists adhere to the position that perceived things in the world can be regarded as either physical or mental depending on whether one is interested in their relationship to other things in the world or their relationship to the perceiver. For example, a red spot on a wall is physical in its dependence on the wall and the pigment of which it is made, but it is mental in so far as its perceived redness depends on the workings of the visual system. Unlike dual-aspect theory, neutral monism does not posit a more fundamental substance of which mind and body are aspects. The most common monisms in the 20th and 21st centuries have all been variations of physicalism; these positions include behaviorism, the type identity theory, anomalous monism and functionalism. Kim, J., "Mind-Body Problem", Oxford Companion to Philosophy. Ted Honderich (ed.). Oxford:Oxford University Press. 1995. Many modern philosophers of mind adopt either a reductive or non-reductive physicalist position, maintaining in their different ways that the mind is not something separate from the body. These approaches have been particularly influential in the sciences, particularly in the fields of sociobiology, computer science, evolutionary psychology and the various neurosciences. Pinel, J. Psychobiology, (1990) Prentice Hall, Inc. ISBN 8815071741 LeDoux, J. (2002) The Synaptic Self: How Our Brains Become Who We Are, New York:Viking Penguin. ISBN 8870787958 Dawkins, R. The Selfish Gene (1976) Oxford:Oxford University Press. ISBN Other philosophers, however, adopt a non-physicalist position which challenges the notion that the mind is a purely physical construct. Reductive physicalists assert that all mental states and properties will eventually be explained by scientific accounts of physiological processes and states. Non-reductive physicalists argue that although the brain is all there is to the mind, the predicates and vocabulary used in mental descriptions and explanations are indispensable, and cannot be reduced to the language and lower-level explanations of physical science. Putnam, Hilary (1967). "Psychological Predicates", in W. H. Capitan and D. D. Merrill, eds., Art, Mind and Religion (Pittsburgh: University of Pittsburgh Press. Continued neuroscientific progress has helped to clarify some of these issues. However, they are far from having been resolved, and modern philosophers of mind continue to ask how the subjective qualities and the intentionality (aboutness) of mental states and properties can be explained in naturalistic terms. Science of mind Psychology is the scientific study of human behaviour, mental functioning, and experience; Noology, the study of thought. As both an academic and applied discipline, Psychology involves the scientific study of mental processes such as perception, cognition, emotion, personality, as well as environmental influences, such as social and cultural influences, and interpersonal relationships, in order to devise theories of human behaviour. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals' daily lives and the treatment of mental health problems. Psychology differs from the other social sciences (e.g., anthropology, economics, political science, and sociology) due to its focus on experimentation at the scale of the individual, or individuals in small groups as opposed to large groups, institutions or societies. Historically, psychology differed from biology and neuroscience in that it was primarily concerned with mind rather than brain. Modern psychological science incorporates physiological and neurological processes into its conceptions of perception, cognition, behaviour, and mental disorders. Social psychology and group behaviour Social psychology is the study of how social conditions affect human beings. Scholars in this field are generally either psychologists or sociologists. Social psychologists who are trained in psychology tend to focus on individuals or small groups as the unit of study; sociologists tend to favor the study of larger groups and larger social units such as societies, although there are exceptions to these general tendencies in both fields. Despite their similarity, the disciplines also tend to differ in their respective goals, approaches, methods, and terminology. They also favor separate academic journals and societies. Like biophysics and cognitive science, social psychology is an interdisciplinary area. The greatest period of collaboration between sociologists and psychologists was during the years immediately following World War II (Sewell, 1989). Although there has been increasing isolation and specialization in recent years, some degree of overlap and influence remains between the two disciplines. Brain In animals the brain, or encephalon (Greek for "in the head"), is the control center of the central nervous system, responsible for thought. In most animals, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, equilibrioception, taste and olfaction. While all vertebrates have a brain, most invertebrates have either a centralized brain or collections of individual ganglia. Primitive animals such as sponges do not have a brain at all. Brains can be extremely complex. For example, the human brain contains more than 100 billion neurons, each linked to as many as 10,000 others. Mental health By analogy with the health of the body, one can speak metaphorically of a state of health of the mind, or mental health. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life." According to the World Health Organization (WHO), there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not necessarily an indicator of mental health. One way to think about mental health is by looking at how effectively and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, maintaining satisfying relationships, and leading an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health. Psychotherapy is an interpersonal, relational intervention used by trained psychotherapists to aid clients in problems of living. This usually includes increasing individual sense of well-being and reducing subjective discomforting experience. Psychotherapists employ a range of techniques based on experiential relationship building, dialogue, communication and behavior change and that are designed to improve the mental health of a client or patient, or to improve group relationships (such as in a family). Most forms of psychotherapy use only spoken conversation, though some also use various other forms of communication such as the written word, art, drama, narrative story, or therapeutic touch. Psychotherapy occurs within a structured encounter between a trained therapist and client(s). Purposeful, theoretically based psychotherapy began in the 19th century with psychoanalysis; since then, scores of other approaches have been developed and continue to be created. Evolutionary history of the human mind The nature and origins of hominid intelligence is of natural interest to humans as the most successful and intelligent hominid species. As nearly a century of archaeological research has shown, the hominids evolved from earlier primates in eastern Africa. Like some non-primate tree-dwelling mammals, such as opossums, they evolved an opposable thumb, which enabled them to grasp and manipulate objects, such as fruit. They also possessed front-facing binocular vision. Around 10 million years ago, the earth's climate entered a cooler and drier phase, which led eventually to the ice ages. This forced tree-dwelling animals to adapt to their new environment or die out. Some primates adapted to this challenge by adopting bipedalism: walking on their hind legs. The advantages of this development are widely disputed. It was once thought that this gave their eyes greater elevation and the ability to see approaching danger further off but as we now know that hominids developed in a forest environment this theory has little real basis. At some point the bipedal primates developed the ability to pick up sticks, bones and stones and use them as weapons, or as tools for tasks such as killing smaller animals or cutting up carcases. In other words, these primates developed the use of technology, an adaptation other animals have not attained to the same capacity as these hominids. Bipedal tool-using primates evolved in the class of hominids, of which the earliest species, such as Sahelanthropus tchadensis, are dated to about 7 million years ago although homonid-made tools were not developed until about 2 million years ago. Thus bipedal hominids existed for 5 million years before they started making tools. The advantage of bipedalism would have been simply to be able to carry anything with survival value from an unfavorable environment to a more favorable one. Anything too big or heavy would have to be broken or cut. This would be an insight that led early minds to develop tools for the purpose. From about 5 million years ago, the hominid brain began to develop rapidly, some say this was because an evolutionary loop had been established between the hominid hand and brain. This theory says that the use of tools conferred a crucial evolutionary advantage on those hominids which had this skill. The use of tools required a larger and more sophisticated brain to co-ordinate the fine hand movements required for this task. However this theory has not been confirmed and many other theories have been developed based on scientific evidence. It is likely that a tool using hominid would have made a formidable enemy and that surviving this new threat would have been the loop that increased brain size and mind power. By 2 million years ago Homo habilis had appeared in east Africa: the first hominid to make tools rather than merely use them. Several more species in the genus 'homo' appeared before fully modern humans, known as homo sapiens developed. These homo sapiens, which are the archaic version of the modern human showed the first evidence of language, and the range of activities we call culture, including art and religion. About 200,000 years ago in Europe and the Near East hominids known to us as Neanderthal man or some call them homo neanderthalensis appeared. They too had art such as decorated tools for aesthetic pleasure and culture, such as burying their dead in ways which suggest spiritual beliefs. hotly debated in the scientific community is whether or not Homo sapiens developed from neanderthals or a combinations of hominids. Some scientists say that the Neanderthals were wiped out by homo sapiens when they entered the region about 40,000 years ago. What is known is that by 25,000 years ago the Neanderthal was extinct. Between 120,000 to 165,000 years ago Homo sapiens reached their fully modern form, the first evidence of this was found in Africa although once again the origins are widely debated between three theories, the Single-Origin theory, the Multiregional model and the Assimilation model. Animal intelligence Animal cognition, or cognitive ethology, is the title given to a modern approach to the mental capacities of animals. It has developed out of comparative psychology, but has also been strongly influenced by the approach of ethology, behavioral ecology, and evolutionary psychology. Much of what used to be considered under the title of animal intelligence is now thought of under this heading. Animal language acquisition, attempting to discern or understand the degree to which animal cognistics can be revealed by linguistics-related study, has been controversial among cognitive linguists. Artificial intelligence The term Artificial Intelligence (AI) was first used by John McCarthy who considers it to mean "the science and engineering of making intelligent machines". WHAT IS ARTIFICIAL INTELLIGENCE? by John McCarthy It can also refer to intelligence as exhibited by an artificial (man-made, non-natural, manufactured) entity. AI is studied in overlapping fields of computer science, psychology, neuroscience and engineering, dealing with intelligent behavior, learning and adaptation and usually developed using customized machines or computers. Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior. Examples include control, planning and scheduling, the ability to answer diagnostic and consumer questions, handwriting, natural language, speech and facial recognition. As such, the study of AI has also become an engineering discipline, focused on providing solutions to real life problems, knowledge mining, software applications, strategy games like computer chess and other video games. One of the biggest difficulties with AI is that of comprehension. Many devices have been created that can do amazing things, but critics of AI claim that no actual comprehension by the AI machine has taken place. The debate about the nature of the mind is relevant to the development of artificial intelligence. If the mind is indeed a thing separate from or higher than the functioning of the brain, then hypothetically it would be much more difficult to recreate within a machine, if it were possible at all. If, on the other hand, the mind is no more than the aggregated functions of the brain, then it will be possible to create a machine with a recognisable mind (though possibly only with computers much different from today's), by simple virtue of the fact that such a machine already exists in the form of the human brain. Religious perspectives Various religious traditions have contributed unique perspectives on the nature of mind. In many traditions, especially mystical traditions, overcoming the ego is considered a worthy spiritual goal. Judaism teaches that "moach shalit al halev", the mind rules the heart. Humans can approach the Divine intellectually, through learning and behaving according to the Divine Will as enclothed in the Torah, and use that deep logical understanding to elicit and guide emotional arousal during prayer. Christianity has tended to see the mind as distinct from the soul (Greek nous) and sometimes further distinguished from the spirit. Western esoteric traditions sometimes refer to a mental body that exists on a plane other than the physical. Hinduism's various philosophical schools have debated whether the human soul (Sanskrit atman) is distinct from, or identical to, Brahman, the divine reality. Buddhism attempted to break with such metaphysical speculation, and posited that there is actually no distinct thing as a human being, who merely consists of five aggregates, or skandhas. According to Buddhist philosopher Dharmakirti, mind is defined as "that which is clarity and cognizes" -- where 'clarity' refers to the formless nature of the mind and 'cognizes' to the function of mind, namely that every mind must cognize an object. Gyatso, Geshe Kelsang Gyatso, Understanding the Mind: The Nature and Power of the Mind, Tharpa Publications (2nd. ed., 1997) ISBN 978-0-948006-78-4 The Indian philosopher-sage Sri Aurobindo attempted to unite the Eastern and Western psychological traditions with his integral psychology, as have many philosophers and New religious movements. Swami Parmanand Ji Maharaj of Bhagwat Bhakti Ashram also gave a very good discourse on The Mind. Taoism sees the human being as contiguous with natural forces, and the mind as not separate from the body. Confucianism sees the mind, like the body, as inherently perfectible. New age and alternative perspectives According to the Parapsychological Association, parapsychology is the scientific study of certain types of paranormal phenomena, or of phenomena which appear to be paranormal. http://parapsych.org/glossary_l_r.html#p Parapsychological Association website, Glossary of Key Words Frequently Used in Parapsychology, Retrieved February 10, 2007 The term is based on the Greek para (beside/beyond), psyche (soul/mind), and logos (account/explanation) and was coined by psychologist Max Dessoir in or before 1889. Its first appearance was in an article by Dessoir in the June 1889 issue of the German publication Sphinx. J. B. Rhine later popularized "parapsychology" as a replacement for the earlier term "psychical research", during a shift in methodologies which brought experimental methods to the study of psychic phenomena. Encyclopedia of Occultism & Parapsychology edited by J. Gordon Melton Gale Research, ISBN 0-8103-5487-X In contemporary research, the term 'parapsychology' refers to the study of psi, a general blanket term used by academic parapsychologists to denote anomalous processes or outcomes. http://www.mdani.demon.co.uk/para/paraglos.htm#P Psychic Science.com http://www.parapsych.org/glossary_l_r.html#p The Parapsychological Association, Inc. (PA) is the international professional organization of scientists and scholars engaged in the study of ‘psi’ The scientific reality of parapsychological phenomena and the validity of scientific parapsychological research is a matter of frequent dispute and criticism. The field is regarded by critics as a pseudoscience. Parapsychologists, in turn, say that parapsychological research is scientifically rigorous. Despite criticisms, a number of academic institutions now conduct research on the topic, employing laboratory methodologies and statistical techniques, such as meta-analysis. The Parapsychological Association is the leading association for parapsychologists and has been a member of the American Association for the Advancement of Science since 1969.

7,748 | Breast_reconstruction | Breast reconstruction is the rebuilding of a breast, usually in women. It involves using autologous tissue or prosthetic material to construct a natural-looking breast. Often this includes the reformation of a natural-looking areola and nipple. This procedure involves the use of implants or relocated flaps of the patient's own tissue. Overview The primary part of the procedure can often be carried out immediately following the mastectomy. As with many other surgeries, patients with significant medical comorbidities (high blood pressure, obesity, diabetes) and smokers are higher-risk candidates. Surgeons may choose to perform delayed reconstruction to decrease this risk. Patients expected to receive external beam radiation as part of their adjuvant treatment are also commonly considered for delayed autologous reconstruction due to significantly higher complication rates with tissue expander-implant techniques in those patients. Breast reconstruction is a large undertaking that usually takes multiple operations. Sometimes these follow-up surgeries are spread out over weeks or months. If an implant is used, the individual runs the same risks and complications as those who use them for breast augmentation but has higher rates of capsular contracture (tightening or hardening of the scar tissue around the implant) and revisional surgeries. Outcomes based research on quality of life improvements and psychosocial benefits associated with breast reconstruction Harcourt, DM, Rumsey, NJ, Ambler, NR, et al. The psychological effect of mastectomy with or without breast reconstruction: a prospective, multicenter study. Plast Reconstr Surg 2003; 111:1060. PMID 12621175 Brandberg, Y, Malm, M, Blomqvist, L. A prospective and randomized study, "SVEA," comparing effects of three methods for delayed breast reconstruction on quality of life, patient-defined problem areas of life, and cosmetic result. Plast Reconstr Surg 2000; 105:66. PMID 10626972 served as the stimulus in the United States for the 1998 Women's Health and Cancer Rights Act, which mandated health care payer coverage for breast and nipple reconstruction, contralateral procedures to achieve symmetry, and treatment for the sequelae of mastectomy. This was followed in 2001 by additional legislation imposing penalties on noncompliant insurers. Similar provisions for coverage exist in most countries worldwide through national health care programs. Techniques There are many methods for breast reconstruction. The two most common are: Tissue Expander - Breast implants This is the most common technique used in worldwide. The surgeon inserts a tissue expander, a temporary silastic implant, beneath a pocket under the pectoralis major muscle of the chest wall. The pectoral muscles may be released along its inferior edge to allow a larger, more supple pocket for the expander at the expense of thinner lower pole soft tissue coverage. The use of acellular human or animal dermal grafts have been described as an onlay patch to increase coverage of the implant when the pectoral muscle is released, which purports to improve both functional and aesthtic outcomes of implant-expander breast reconstruction. Breuing KH, Warren SM. Immediate bilateral breast reconstruction with implants and inferolateral AlloDerm slings. Ann Plast Surg. 2005 Sep;55(3):232-9. PMID: 16106158 Salzberg CA. Nonexpansive immediate breast reconstruction using human acellular tissue matrix graft (AlloDerm). Ann Plast Surg. 2006 Jul;57(1):1-5. PMID 16799299 In a process that can take weeks or months, saline solution is percutaneously injected to progressively expand the overlaying tissue. Once the expander has reached an acceptable size, it may be removed and replaced with a more permanent implant. Reconstruction of the areola and nipple are usually performed in a separate operation after the skin has stretched to its final size. Flap reconstruction The second most common procedure uses tissue from other parts of the patient's body, such as the back, buttocks, thigh or abdomen. This procedure may be performed by leaving the donor tissue connected to the original site to retain its blood supply (the vessels are tunnelled beneath the skin surface to the new site) or it may be cut off and new blood supply may be connected. The latissimus dorsi muscle flap is the donor tissue available on the back. It is a large flat muscle which can be employed without significant loss of function. It can be moved into the breast defect still attached to its blood supply under the arm pit (axilla). A latissimus flap is usually used to recruit soft-tissue coverage over an underlying implant. Enough volume can be recruited occasionally to reconstruct small breasts without an implant. Abdominal flaps The abdominal flap for breast reconstruction is the TRAM flap or its technically distinct variants of microvascular "perforator flaps" like the DIEP/SIEP flaps. Both use the abdominal tissue between the umbilicus and the pubis. The DIEP flap and free-TRAM flap require advanced microsurgical technique and are less common as a result. Both can provide enough tissue to reconstruct large breasts. The contour of the lower abdomen is reliably improved by these procedures which remove the same tissue as an abdominoplasty (tummy tuck.) TRAM flap procedures may weaken the abdominal wall and torso strength, but are tolerated well in most patients. To prevent muscle weakness and incisional hernias, the portion of abdominal wall exposed by reflection of the rectus abdominis muscle may be strengthened by a piece of surgical mesh placed over the defect and sutured in place. Perforator techniques such as the DIEP (deep inferior epigastric perforator) flap and SIEA (superficial inferior epigastric artery) flap require precise dissection of small perforating vessels through the rectus muscle, and purport the advantage of less weakening of the abdominal wall, though rectus abdominus muscle function may still be compromised. Other total autologous tissue breast reconstruction donor sites include the buttocks (superior or inferior gluteal artery perforator flaps (SGAP or IGAP)). The purpose of perforator flaps (DIEP, SIEA, SGAP, IGAP) is to provide sufficient skin and fat for an aesthetic reconstruction while minimizing morbidity from harvesting the underlying muscles. The TRAM Flap Procedure Identification of the target and donor sites Raising the flap and transposing it to the target site The result of the reconstruction Other considerations Nipple reconstruction is usually delayed until after the breast mound reconstruction is completed so that the positioning can be planned precisely. There are several methods of reconstructing the nipple-areolar complex, including: Nipple-Areolar Composite Graft (Sharing) - if the contralateral breast has not been reconstructed and the nipple and areolar are sufficiently large, tissue may be harvested and used to recreate the nipple-areolar complex on the reconstructed side. Local Tissue Flaps - a nipple may be created by raising a small flap in the target area and producing a raised mound of skin. To create an areola, a circular incision may be made around the new nipple and sutured back again. The nipple and areolar region may then be tattooed to produce a realistic colour match with the contralateral breast. Local Tissue Flaps With Use of AlloDerm - as above, a nipple may be created by raising a small flap in the target area and producing a raised mound of skin. AlloDerm (cadaveric dermis) can then be inserted into the core of the new nipple acting like a "strut" which may help maintain the projection of the nipple for a longer period of time. The nipple and areolar region may then be tattooed later. Charles E. Garramone, D.O.; Benjamin Lam, D.O.:"Use of AlloDerm in Primary Nipple Reconstruction to Improve Long-Term Nipple Projection" Plastic & Reconstructive Surgery Journal, May 2007, Volume 119, Issue 6, PMID: 17440338 One of the challenges in breast reconstruction is to match the reconstructed breast to the mature breast on the other side (often fairly 'ptotic' - droopy.) This often requires a lift (mastopexy), reduction, or augmentation of the other breast. Follow-up and Recovery Recovery from implant-based reconstruction is generally faster than with flap-based reconstructions, but both take at least three to six weeks to recover and both require follow-up surgeries in order to construct a new areola and nipple. All recipients of these operations should refrain from strenuous sports, overhead lifting and sexual activity during the recovery period (three to six weeks). TRAM flap patients can show abdominal muscle weakness on EMG studies, but clinically most patients who have undergone unilateral breast reconstruction (reconstruction of one breast only) return to normal activities after recovery. Patients who have undergone bilateral breast reconstruction with TRAM flaps (ie reconstruction of both breasts) require sacrifice of both rectus muscles and tend to have permanent abdominal strength loss. For this reason, many plastic surgeons now frown upon bilateral breast reconstruction with TRAM flaps. This also explains the significant patient interest in perforator flap techniques such as the DIEP flap which preserves abdominal muscle function long term. These patients tend to return to full activity after several weeks without permanent limitations. There is little information about upper body exercise post-mastectomy. Issues such as simple mastectomy, mastectomy with reconstruction, mastectomy with lymph node excision and reconstruction all factor into limitations to amount and extent of upper body exercise. Generally, cardiac exercise (treadmill, walking, etc.) are approved for rehabilitation post-surgery and for weight control. Women who have undergone breast reconstruction must still be followed for local or regional recurrence of their cancer with manual exams of the breast/chest wall and axilla.

7,749 | Jason | Jason (Greek: Ἰάσων, Etruscan: Easun, Laz: Yason) was a late ancient Greek mythological figure, famous as the leader of the Argonauts and their quest for the Golden Fleece. He was the son of Aeson, the rightful king of Iolcus. He was married to the sorceress Medea. Jason is considered to be one of the heroes of Greek mythology, along with such others as Herakles and Odysseus. Jason appeared in various literature in the classical world of Greece and Rome, including the epic poem Argonautica and tragedian play, Medea. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the film Jason and the Argonauts. Jason has connections outside of the classical world, as he is seen as being the mythical founder of the city of Ljubljana, the capital of Slovenia. Early years Pelias (Aeson's half-brother) was very power-hungry, and he wished to gain dominion over all of Thessaly. Pelias was the product of a union between their shared mother, Tyro ("high born Tyro") the daughter of Salmoneus, and the sea god Poseidon. In a bitter feud, he overthrew Aeson (the rightful king), killing all the descendants of Aeson that he could. He spared his half-brother for unknown reasons. Alcimede I (wife of Aeson) already had an infant son named Jason whom she saved from being killed by Pelias, by having women cluster around the newborn and cry as if he were still-born. Alcimede sent her son to the centaur Chiron for education, for fear that Pelias would kill him - she claimed that she had been having an affair with him all along. Pelias, still fearful that he would one day be overthrown, consulted an oracle which warned him to beware of a man with one sandal. Many years later, Pelias was holding games in honor of the sea god and his alleged father, Poseidon, when Jason arrived in Iolcus and lost one of his sandals in the river Anauros ("wintry Anauros"), while helping an old woman (the Goddess Hera in disguise), to cross. She blessed him for she knew, as goddesses do, what Pelias had up his sleeve. When Jason entered Iolcus (modern-day city of Volos), he was announced as a man wearing one sandal. Jason, knowing that he was the rightful king, told Pelias that and Pelias said, "To take my throne, which you shall, you must go on a quest to find the Golden Fleece." Jason happily accepted the quest. The Quest for the Golden Fleece Jason bringing Pelias the Golden Fleece, Apulian red-figure calyx krater, ca. 340 BC–330 BC, Louvre Jason assembled a great group of heroes, known as the Argonauts after their ship, the Argo. The group of heroes included the Boreads (sons of Boreas, the North Wind) who could fly, Heracles, Philoctetes, Peleus, Telamon, Orpheus, Castor and Pollux, Atalanta, and Euphemus. The Isle of Lemnos The isle of Lemnos is situated off the Western coast of Asia Minor (modern day Turkey). The island was inhabited by a race of women who had killed their husbands. The women had neglected their worship of Aphrodite, and as a punishment the goddess made the women so foul in stench that their husbands couldn't bear to be near them. The men then took concubines from the Thracian mainland opposite, and the spurned women, angry at Aphrodite, killed every male inhabitant while they slept. The king, Thoas, was saved by Hypsipyle, his daughter, who put him out to sea sealed in a chest from which he was later rescued. The women of Lemnos lived for a while without men, with Hypsipyle as their queen. During the visit of the Argonauts the women mingled with the men creating a new "race" called Minyae. Jason fathered twins with the queen. Heracles pressured them to leave as he was disgusted by the antics of the Argonauts. He hadn't taken part, which is truly unusual considering the numerous affairs he had with other women. [Note: In "Hercules, My Shipmate" Robert Graves claims that Heracles fathered more children than anyone else of the crew.] Kyzicos After Lemnos the Argonauts landed among the Doliones, whose king Kyzicos treated them graciously. The Argonauts departed, losing their bearings and landing again at the same spot that night. In the darkness, the Doliones took them for enemies and they started fighting each other. The Argonauts killed many of the Doliones, among them the king Kyzicos. Kyzicos' wife killed herself. The Argonauts realized their horrible mistake when dawn came. Mysia When the Argonauts reached Mysia, they sent some men to find food and water. Among these men was Heracles' servant, Hylas. The nymphs of the stream where Hylas was collecting were attracted to his good looks, and pulled him into the stream. Heracles returned to his Labors, but Hylas was lost forever. Others say that Heracles went to Colchis with the Argonauts and he got the Golden Girdle of the Amazons and slew the Stymphalian Birds at that time. Phineus and the Harpies Soon Jason reached the court of Phineus of Salmydessus in Thrace. Phineus had been given the gift of prophecy by Apollo, but was later given the choice of being blind and having a long life, or having sight and having a short life, for revealing to humans the deliberations of the gods. He chose to be blind. Helios the sun god sent the Harpies, creatures with the body of a bird and the head of a woman, to prevent Phineus from eating any more than what was necessary to live, because he was enraged that Phineus had chosen to live in a continual state of darkness than live in the sun he provided. Jason took pity on the emaciated king and killed the Harpies when they returned (In other versions Calais and Zetes chase the Harpies away). In return for this favor, Phineus revealed to Jason the location of Colchis and how to cross the Symplegades, or The Clashing Rocks, and then they parted. The Symplegades The only way to reach Colchis was to sail through the Symplegades (Clashing Rocks), huge rock cliffs that came together and crushed anything that traveled between them. Phineus told Jason to release a dove when they approached these islands, and if the dove made it through, to row with all their might. If the dove was crushed, he was doomed to fail. Jason released the dove as advised, which made it through, losing only a few tail feathers. Seeing this, they rowed strongly and made it through with minor damage at the extreme stern of the ship. From that time on, the clashing rocks were forever joined leaving free passage for others to pass. The Arrival in Colchis Jason and the Snake Jason arrived in Colchis (modern Black Sea coast of Georgia) to claim the fleece as his own. King Aeetes of Colchis promised to give it to him only if he could perform three certain tasks. Presented with the tasks, Jason became discouraged and fell into depression. However, Hera had persuaded Aphrodite to convince her son Eros to make Aeetes's daughter, Medea, fall in love with Jason. As a result, Medea aided Jason in his tasks. First, Jason had to plow a field with fire-breathing oxen, the Khalkotauroi, that he had to yoke himself. Medea provided an ointment that protected him from the oxen's flames. Then, Jason sowed the teeth of a dragon into a field. The teeth sprouted into an army of warriors. Medea had previously warned Jason of this and told him how to defeat this foe. Before they attacked him, he threw a rock into the crowd. Unable to discover where the rock had come from, the soldiers attacked and defeated one another. His last task was to overcome the Sleepless Dragon which guarded the Golden Fleece. Jason sprayed the dragon with a potion, given by Medea, diluted from herbs. The dragon fell asleep, and Jason was able to seize the Golden Fleece. He then sailed away with Medea. Medea had to distract her father, who chased them, as they fled by killing her brother Apsyrtus and throwing pieces of his body into the sea, which Aeetes had to stop for and gather. In another version, Medea lured Apsyrtus into a trap. Jason kills him, chops off his fingers and toes, and buries the corpse. In any case, Jason and Medea escaped. Return journey On the way back to Iolcus, Medea prophesised to Euphemus, the Argo's helmsman, that one day he would rule Libya. This came true through Battus, a descendant of Euphemus. Zeus, as punishment for the slaughter of Medea's own brother, sent a series of storms at the Argo and blew it off course. The Argo then spoke and said that they should seek purification with Circe, a nymph living on the island called Aeaea. After being cleansed, they continued their journey home. Sirens Chiron had told Jason that without the aid of Orpheus, the Argonauts would never be able to pass the Sirens — the same Sirens encountered by Odysseus in Homer's epic poem the Odyssey. The Sirens lived on three small, rocky islands called Sirenum scopuli and sang beautiful songs that enticed sailors to come to them, which resulted in the crashing of their ship into the islands. When Orpheus heard their voices, he drew his lyre and played music that was more beautiful and louder, drowning out the Sirens' bewitching songs. Talos The Argo then came to the island of Crete, guarded by the bronze man, Talos. As the ship approached, Talos hurled huge stones at the ship, keeping it at bay. Talos had one blood vessel which went from his neck to his ankle, bound shut by only one bronze nail (as in metal casting by the lost wax method). Medea cast a spell on Talos to calm him; she removed the bronze nail and Talos bled to death. The Argo was then able to sail on. Jason returns Medea, using her sorcery, claimed to Pelias' daughters that she could make their father younger by chopping him up into pieces and boiling the pieces in a cauldron of water and magical herbs. She demonstrated this remarkable feat with a sheep, which leapt out of the cauldron as a lamb. The girls, rather naively, sliced and diced their father and put him in the cauldron. Medea did not add the magical herbs, and Pelias was dead. [It should be noted that Thomas Bulfinch has an antecedent to the interaction of Medea and the daughters of Pelias. Jason, celebrating his return with the Golden Fleece, noted that his father was too aged and infirm to participate in the celebrations. He had seen and been served by Medea's magical powers. He asked Medea to take some years from his life and add them to the life of his father. She did so, but at no such cost to Jason's life. {See Thomas Bulfinch, page 134; compare to Shakespeare's witches in Macbeth.} Pelias' daughters saw this and wanted the same service for their father.] Pelias' son, Acastus, drove Jason and Medea into exile for the murder, and the couple settled in Corinth. Treachery of Jason In Corinth, Jason became engaged to marry Creusa (sometimes referred to as Glauce), a daughter of the King of Corinth, to strengthen his political ties. When Medea confronted Jason about the engagement and cited all the help she had given him, he retorted that it was not she that he should thank, but Aphrodite who made Medea fall in love with him. Infuriated with Jason for breaking his vow that he would be hers forever, Medea took her revenge by presenting to Creusa a cursed dress, as a wedding gift, that stuck to her body and burned her to death as soon as she put it on. Creusa's father, Creon, burned to death with his daughter as he tried to save her. Then Medea killed the two boys that she bore to Jason, fearing that they would be murdered or enslaved as a result of their mother's actions. When Jason came to know of this, Medea was already gone; she fled to Athens in a chariot sent by her grandfather, the sun-god Helios. Later Jason and Peleus, father of the hero Achilles, would attack and defeat Acastus, reclaiming the throne of Iolcus for himself once more. Jason's son, Thessalus, then became king. Because he broke his vow to love Medea forever, Jason lost his favor with Hera and died lonely and unhappy. He was asleep under the stern of the rotting Argo when it fell on him, killing him instantly. The manner of his death was due to the deities cursing him for breaking his promise to Medea. In classical literature Epic poetry Though some of the episodes of Jason's story draw on ancient material, the definitive telling, on which this account relies, is that of Apollonius of Rhodes in his epic poem Argonautica, written in Alexandria in the late 3rd century BC. Another Argonautica was written by Gaius Valerius Flaccus in the late 1st century AD, comprising of eight books in length. The poem ends abruptly with the request of Medea to accompany Jason on his homeward voyage. It is unclear if part of the epic poem has been lost, or if it had ever been finished. A third version is the Argonautica Orphica, which emphasizes the role of Orpheus in the story. Jason is breafly mentioned in Dante's Divine Comedy. He appears in the Canto XVIII. In it, he is seen by Dante and his guide Virgil being punished in Hell's Eighth Circle (Bolgia 1) by being driven to march through the circle for all eternity while being whipped by devils. He is included among the seducers (possibly for his seduction and subsequent uncare of Medea). Drama The story of Medea's revenge on Jason is told with devastating effect by Euripides in his tragedy Medea. Non-fiction The mythical geography of the voyage of the Argonauts has been speculatively explicated by the historian of science and the cartography of Antiquity, Livio Catullo Stecchini, in a suggestive essay, The Voyage of the Argo, that draws upon fragments of the mythic sources Apollonius employed in constructing his poem. In popular culture Literature The novel Jason (1961) by Henry Treece is narrated by Jason himself. The supernatural elements are largely removed, but a major theme of the book is the clash between the older religion of the mother goddess, favoured by women (who are portrayed as dangerous and hostile to men in many ways) and the newer religion of Zeus and Poseidon favoured by men. Film Two movies titled Jason and the Argonauts have been produced: Jason and the Argonauts (1963), directed by Don Chaffey, and Jason and the Argonauts (2000), a Hallmark presentation TV movie. A 1958 spaghetti production of Hercules starring Steve Reeves, featured Jason and the Argonauts, as well as Ulysses. In the children's show, Class of the Titans, one of the main characters, Jay, is a descendant of Jason, and the characters have run-ins with Medea and Talos. Jason was also portrayed by Jeffrey Thomas (with Chris Conrad as young Jason) in Hercules: The Legendary Journeys. Lars Von Trier's made for TV movie entitled Medea (1988) depicts Udo Kier as Jason after he has retrieved the Golden fleece. The Michael Eisner-produced web show The All-for-nots is loosely based on the Argonautika, as an indie rock band whose name vaguely rhymes with `The Argonauts' tours America on their way to the golden fleece of rock stardom. A documentary named "In Search of Myths and Heroes" by Michael Wood, third episode talks about Jason the Myth. The 2008 TV series AGE OF THE GODS: JOURNEYS EDITION, did their 2nd episode, JASON, based on the myth of Jason, telling the parts about King Pelias, the Argonauts, the Isles of Lemnos, Phineus and the Harpies, the Symplegades, Medea, the Iron Bulls and Sown Men, the Golden Fleece, the Betrayal of Medea, and the Death of Jason. Stage Mary Zimmerman wrote and directed Argonautika, which premiered in 2006 with the Chicago Lookingglass Theatre Company. It tells the story of Jason and the Argonauts from Pelias' initial charge through Jason's betrayal of Medea. Euripides wrote the play Medea, which is focused around the period which leads to Medea killing Jason's bride and their two children. This play has nine characters as well as a chorus role. Music The They Might Be Giants song Birdhouse in Your Soul the band mentions that a night light would be a poor substitute for a lighthouse, resulting in the death of Jason and the Argonauts. Radio In 2001, a radio drama adaptation of Apollonius' Argonautica, was produced by the Radio Tales series for National Public Radio. Sports Jason is the team mascot of the Toronto Argonauts in the Canadian Football League. Video games Jason is shown being devoured by Cerberus in the hit Playstation 2 video game God of War 2, before the player attempts to retrieve the Golden Fleece. In Age of Mythology, Jason is a Greek hero character that can be purchased from the town center for use in combat. Rise of the Argonauts is a role-playing game which follows Jason and the Argonauts on their quest to find the Golden Fleece. Jason appears in the 1997 console video game Herc's Adventures as one of the three playable characters. See also Mermeros and Pheres Cape Jason References Bibliography Publius Ovidius Naso.

7,750 | Kermit_the_Frog | Kermit the Frog is a Muppet, one of puppeteer Jim Henson's most famous creations, first introduced in 1955. Kermit was performed by Henson until his death in 1990. Since then he has been performed by Steve Whitmire. He was voiced by Frank Welker in Muppet Babies and occasionally in animation. Kermit's development An early version of Kermit appeared in 1955, in a five-minute puppet show for WRC-TV's Sam and Friends. The prototype Kermit was created from a green ladies' coat that Henson's mother had thrown into a waste bin, and two ping pong balls for eyes. Initially, Kermit was seen as a lizard-like creature. He subsequently made a number of television appearances before his status as a frog was established, which was shortly before Sesame Street began. His collar was added at the time to make him seem more froglike and to conceal the seam between his head and body. The chief reason that Jim Henson chose Kermit as his main character was that Kermit, being lightweight, was easier to perform for long periods of time (in terms of personality, the Muppet Henson most closely identified himself with was Rowlf the Dog). Kermit's song "The Rainbow Connection" was also a big hit from The Muppet Movie and, for some time, had become something of a signature song for The Jim Henson Company. Naming On more than one occasion the press has stated that Kermit's name was taken from Jim Henson's childhood friend, Kermit Scott, from Leland, Mississippi. While this rumor has persisted over the years, it is not true. The Jim Henson Company has gone on record to deny this claim as declared by Henson himself. Karen Falk, who sits on the Board of Directors for the Jim Henson Legacy and serves as head archivist for the company, published the denial on the company's official website, Henson.com: As Sesame Street is localized for some different markets that speak languages other than English, Kermit is often renamed. In Portugal, he's Cocas, o Sapo (sapo means toad). In Latin America, his name is la rana René (René the Frog). In Spain, Kermit is named Gustavo. In France and the Canadian province of Quebec, he is known as Kermit la grenouille. In Brazil, his name is Caco, o Sapo. In the Arabic Middle Eastern version, he's known as Kamel, which is a common Arabic male name that means "perfect"). In Hungary he is called Breki. Character biography On an episode of Extreme Makeover: Home Edition, Kermit commented to Ty Pennington, "You know, as a tadpole in the swamp, I had 3,265 brothers and sisters!" According to Kermit's Swamp Years, at the age of 12, he was the first of his siblings to leave the swamp, and one of the first frogs to talk to humans. He is portrayed as encountering a 12-year-old Jim Henson (played by Christian Kebbel) for the first time. According to The Muppet Movie Kermit returned to the swamp, where a passing agent noted he had talent and, thus inspired, he headed to Hollywood, encountering the rest of the Muppets along the way. Together, they were given a standard "rich and famous" contract by Lew Lord of Wide World Studios and began their showbiz careers. Appearances Kermit's earliest incarnation on Sam and Friends Sesame Street Kermit was one of the original Muppet characters on Sesame Street. Though he was intended to be removed from the cast after the first season, he returned as a full-time character in the third, and remained a regular character for many years. Closely identified with the show, he often appeared as an easily frustrated lecturer, a straight man to the humorous antics of another Muppet, or a news reporter interviewing storybook characters for Sesame Street News. He most often interacted with Grover and, to a slightly lesser extent, Cookie Monster. The various songs he sang on Sesame Street tended to be meaningful in nature, most memorably his song "Bein' Green". Following the death of Jim Henson, Kermit was used less frequently on Sesame Street, but still made new appearances until 2001. Unlike the rest of the show's Muppets, he was not created for the exclusive use of Sesame Workshop, and has rarely been a part of the show's merchandise. All Muppet characters originally belonged to the Jim Henson Company, but when the opportunity came for Sesame Workshop to buy its characters for $180 million, Kermit was not included in the deal. The character now belongs to The Muppets Studio; however, Sesame Workshop does have permission to use old sketches featuring Kermit. With the Muppets In The Muppet Show television series, Kermit was the central character, the frontman and the long-suffering stage manager of the theatre show, trying to keep order amidst the chaos created by the other Muppets. Jim Henson once claimed that Kermit's job on the Muppet Show was much like his own: "trying to get a bunch of crazies to actually get the job done." It was on this show that the running joke of Kermit being pursued by leading lady Miss Piggy developed. On Muppets Tonight, Kermit was still a main character, although he was the producer rather than frontman. He appeared in many parody sketches such as NYPD Green, City Schtickers, Flippers, and The Muppet Odd Squad, as well as in the Psychiatrist's Office sketch. Kermit also served as the mascot for The Jim Henson Company, until the sale of the Muppet characters to The Walt Disney Company. A Kermit puppet can be seen at the National Museum of American History. NMAH | Kermit the Frog Puppet Kermit has also played a central role in most of the Muppet movies except for Muppets From Space which was focused on Gonzo the Great. Guest appearances and parodies Kermit has made numerous guest appearances on popular television shows, including co-hosting individual episodes of a number of long-running talk shows: On April 2, 1979, Kermit guest-hosted The Tonight Show Starring Johnny Carson, and as an April Fool's joke, Kermit hosted CNN's Larry King Live in 1994 and interviewed Hulk Hogan. Tough Pigs Anthology - April Frog's Day: Kermit on Larry King Live Kermit was also a semi-regular during the last two seasons of the Tom Bergeron-hosted Hollywood Squares, continuing a quasi-tradition of Muppets appearing on the game show (Big Bird and Oscar the Grouch made several appearances on the original Squares). Most of Kermit's appearances as a guest star include him being treated as a "real" (non-puppet) character. This ´pretense has been continued into other media: In 1993 Pocket Books published One Frog Can Make A Difference, Kermit's Guide to Life with Kermit as the author. In 1987, Kermit and other Muppet characters co-hosted an ABC News special which attempted to explain the stock market and the potentially disquieting events of the Black Monday stock price decline in a manner that both informed and entertained the audience about the complex subject. He appears as a game contestant on the show To Tell The Truth. Kermit has a TV star on the Hollywood Walk of Fame located at 6801 Hollywood Blvd.) Kermit also guest appeared on An Audience With... Kylie Minogue, Kermit & Kylie performed a duet of her hit song Especially For You. It aired on ITV in the on October 6, 2001. His popularity has also led to his appearance in advertisements for a range of products: In January 2006, in a commercial for the Ford Escape Hybrid premiering during the Super Bowl, Kermit was featured singing "Bein' Green"; he is also featured in Ford's print ads for their hybrid vehicle. He also has co-starred alongside Miss Piggy and Jessica Simpson in Pizza Hut commercials in previous Super Bowl commercials. In previous years, he and Miss Piggy were part of the "We want to race the truck" UPS ad campaign involving NASCAR driver Dale Jarrett and his sponsor's "prodding" him to drive a brown UPS truck in a race. Due to his popularity, easy recognizability, and distinctive voice, Kermit has become a popular target for parody: Kermit has been referenced dozens of times on several television series and films, as Vomiting Kermit on Late Night with Conan O'Brien, on Family Guy, Meet the Feebles, in the Internet fan video Sad Kermit and Kermit Bale, a series of photos comparing him to actor Christian Bale. For a comprehensive list of Kermit parodies, see the Muppet Mentions category on Muppet Wiki. Awards and commemorations Kermit was awarded an honorary doctorate of Amphibious Letters on May 19, 1996 at Southampton College, New York, where he also gave a commencement speech. Southampton College News: Kermit's Commencement Address at Southampton College He is also the only amphibian to have had the honor of addressing the Oxford Union. The New York Times A statue of Henson and Kermit was erected on the campus of Henson's alma mater, the University of Maryland, College Park in 2003. Kermit was also given the honor of being the Grand Marshal of the Tournament of Roses Parade in 1996. On Kermit's 50th anniversary in show business, the United States Postal Service released a set of new stamps with photos of Kermit and some of his fellow Muppets on them. The background of the stamp sheet features a photo of a silhouetted Henson sitting in a window well, with Kermit sitting in his lap looking at him. In 2006, on Kermit's 50th anniversary, Kermit, Texas was taken over by the frog during their homecoming week, ending with Kermit himself crowning the homecoming queen. The city of Kermit's main water tower was then painted with the face and signature of the frog. Filmography Hey, Cinderella!

7,751 | Claudius_Aelianus | Aelianus Tacticus, Greek military writer of the 2nd century CE, resident at Rome, is sometimes confused with Claudius Aelianus. Claudius Aelianus (ca. 175–ca. 235), often seen as just Aelian, born at Praeneste, was a Roman author and teacher of rhetoric who flourished under Septimius Severus and probably outlived Elagabalus, who died in 222. He spoke Greek so perfectly that he was called "honey-tongued" (meliglossos); Roman-born, he preferred Greek authors, and wrote in a slightly archaizing Greek himself. His two chief works are valuable for the numerous quotations from the works of earlier authors, which are otherwise lost, and for the surprising lore, which offers unexpected glimpses into the Greco-Roman world-view. De Natura Animalium (Περὶ Ζῴων Ἰδιότητος) On the Nature of Animals, ("On the Characteristics of Animals" is an alternative title; usually cited, though, by its Latin title), is a curious collection, in 17 books, of brief stories of natural history, sometimes selected with an eye to conveying allegorical moral lessons, sometimes because they are just so astonishing: "The Beaver is an amphibious creature: by day it lives hidden in rivers, but at night it roams the land, feeding itself with anything that it can find. Now it understands the reason why hunters come after it with such eagerness and impetuosity, and it puts down its head and with its teeth cuts off its testicles and throws them in their path, as a prudent man who, falling into the hands of robbers, sacrifices all that he is carrying, to save his life, and forfeits his possessions by way of ransom. If however it has already saved its life by self-castration and is again pursued, then it stands up and reveals that it offers no ground for their eager pursuit, and releases the hunters from all further exertions, for they esteem its flesh less. Often however Beavers with testicles intact, after escaping as far away as possible, have drawn in the coveted part, and with great skill and ingenuity tricked their pursuers, pretending that they no longer possessed what they were keeping in concealment." The Loeb Classical Library introduction characterizes the book as "an appealing collection of facts and fables about the animal kingdom that invites the reader to ponder contrasts between human and animal behavior." Aelian's anecdotes on animals rarely depend on direct observation: they are almost entirely taken from written sources, often Pliny the Elder, but also other authors and works now lost, to whom he is thus a valuable witness. The third volume of the Loeb Classical Library translation gives a gazetteer of authors cited by Aelian. He is more attentive to marine life than might be expected, though, and this seems to reflect first-hand personal interest; he often quotes "fishermen". At times he strikes the modern reader as thoroughly credulous, but at others he specifically states that he is merely reporting what is told by others, and even that he does not believe them. Aelian's work is one of the sources of medieval natural history and of the bestiaries of the Middle Ages; in some ways an allegory of the moral world, an Emblem Book. The text as it has come down to us is badly mangled and garbled and replete with later interpolations. "Aelian's text, riddled as it is with corrupt passages and packed with interpretations,provides ample scope for reckless emendation," D. E. Eichholz observed, reviewing Sholfield's Loeb Library translation in The Classical Review 1960:219, and praising the translator for restrait in this direction. Conrad Gessner (or Gesner), the Swiss scientist and natural historian of the Renaissance, made a Latin translation of Aelian's work, to give it a wider European audience. An English translation by A. F. Scholfield has been published in the Loeb Classical Library, 3 vols. (19[ ]-59). Varia Historia (Ποικίλη Ἱστορία) Various History — for the most part preserved only in an abridged form — is Aelian's other well-known work, a miscellany of anecdotes and biographical sketches, lists, pithy maxims, and descriptions of natural wonders and strange local customs, in 14 books, with many surprises for the cultural historian and the mythographer, anecdotes about the famous Greek philosophers, poets, historians, and playwrights and myths instructively retold. The emphasis is on various moralizing tales about heroes and rulers, athletes and wise men; reports about food and drink, different styles in dress or lovers, local habits in giving gifts or entertainments, or in religious beliefs and death customs; and comments on Greek painting. Aelian gives an account of fly fishing, using lures of red wool and feathers, of lacquerwork, serpent worship — Essentially the Various History is a Classical "magazine" in the original senses of that word. He is not perfectly trustworthy in details, and his agenda is always to inculcate culturally "correct" Stoic opinions, perhaps so that his readers will not feel guilty, but Jane Ellen Harrison found survivals of archaic rites mentioned by Aelian very illuminating in her Prolegomena to the Study of Greek Religion (1903, 1922). The first printing was in 1545. The standard modern text is Mervin R. Dilts's, of 1974. Two English translations of the Various History, by Fleming (1576) and Stanley (1665) made Aelian's miscellany available to English readers, but after 1665 no English translation appeared, until three English translations appeared almost simultaneously: James G. DeVoto, Claudius Aelianus: Ποιϰίλης Ἱοτορίας ("Varia Historia") Chicago, 1995; Diane Ostrom Johnson, An English Translation of Claudius Aelianus' "Varia Historia", 1997; and N. G. Wilson, Aelian: Historical Miscellany in the Loeb Classical Library. Other works Considerable fragments of two other works, On Providence and Divine Manifestations, are preserved in the early medieval encyclopedia, the Suda. Twenty "letters from a farmer" after the manner of Alciphron are also attributed to him. The letters are invented compositions to a fictitious correspondent, which are a device for vignettes of agricultural and rural life, set in Attica, though mellifluous Aelian once boasted that he had never been outside Italy, never been aboard a ship (which is at variance, though, with his own statement, de Natura Animalium XI.40, that he had seen the bull Serapis with his own eyes). Thus conclusions about actual agriculture in the Letters are as likely to evoke Latium as Attica. The fragments have been edited in 1998 by D. Domingo-Foraste, but are not available in English. The Letters are available in the Loeb Classical Library, translated by Allen Rogers Benner and Francis H. Fobes (1949).

7,752 | Horner's_method | In numerical analysis, the Horner scheme or Horner algorithm, named after William George Horner, is an algorithm for the efficient evaluation of polynomials in monomial form. Horner's method describes a manual process by which one may approximate the roots of a polynomial equation. The Horner scheme can also be viewed as a fast algorithm for dividing a polynomial by a linear polynomial with Ruffini's rule. Description of the algorithm Given the polynomial where are real numbers, we wish to evaluate the polynomial at a specific value of x, say x0. To accomplish this, we define a new sequence of constants as follows: Then b0 is the value of p(x0). To see why this works, note that the polynomial can be written in the form Thus, by iteratively substituting the into the expression, Examples Evaluate for . By repeatedly factoring out , may be rewritten as . We use a synthetic diagram to organize these calculations and make the process faster. | 3 | 2 -6 2 -1 | 6 0 6 |---------------------- 2 0 2 5 The entries in the third row are the sum of those in the first two. Each entry in the second row is the product of the x-value (3 in this example) with the third-row entry immediately to the left. The entries in the first row are the coefficients of the polynomial to be evaluated. The answer is 5. As a consequence of the polynomial remainder theorem, the entries in the third row are the coefficients of the second-degree polynomial that is the quotient of f1/(x-3). The remainder is 5. This makes Horner's method useful for polynomial long division. Divide by : 2 | 1 -6 11 -6 | 2 -8 6 |---------------------- 1 -4 3 0 The quotient is . Let and . Divide by using Horner's scheme. 2 | 4 -6 0 3 | -5 ---------------------------|------ 1 | 2 -2 -1 | 1 | | |----------------------|------- 2 -2 -1 1 | -4 The third row is the sum of the first two rows, divided by 2. Each entry in the second row is the product of 1 with the third-row entry to the left. The answer is Floating point multiplication and division Horner's method is a fast, code-efficient method for multiplication and division of binary numbers on a microcontroller with no math coprocessor. One of the binary numbers to be multiplied is represented as a trivial polynomial, where, (using the above notation): ai = 1, and x = 2. Then, x (or x to some power) is repeatedly factored out. In this binary numeral system (base 2), x = 2, so powers of 2 are repeatedly factored out. Example For example, to find the product of two numbers, (0.15625) and m: Method To find the product of two binary numbers, "d" and "m". 1. A register holding the intermediate result is initialized to (d). 2. Begin in (m) with the least significant (rightmost) non-zero bit, 2b. Count (to the left) the number of bit positions to the next most significant non-zero bit. If there are no more-significant bits, then take the value of the current bit position. 2c. Using that value, perform a right-shift operation by that number of bits on the register holding the intermediate result 3. If all the non-zero bits were counted, then the intermediate result register now holds the final result. Otherwise, add (d) to the intermediate result, and continue in step #2 with the next most significant bit in (m). Derivation In general, for a binary number with bit values: () the product is: At this stage in the algorithm, it is required that terms with zero-valued coefficients are dropped, so that only binary coefficients equal to one are counted, thus the problem of multiplication or division by zero is not an issue, despite this implication in the factored equation: The denominators all equal one (or the term is absent), so this reduces to: or equivalently (as consistent with the "method" described above): In binary (base 2) math, multiplication by a power of 2 is merely an register shift operation. Thus, multiplying by 2 is calculated in base-2 by a right arithmetic shift. The factor (2-1) is a right arithmetic shift, a (0) results in no operation (since 20 = 1, is the multiplicative identity element), and a (21) results in a left arithmetic shift. The multiplication product can now be quickly calculated using only arithmetic shift operations, addition and subtraction. The method is particularly fast on processors supporting a single-instruction shift-and-addition-accumulate. Compared to a C floating-point library, Horner's method sacrifices some accuracy, however it is nominally 13 times faster (16 times faster when the "canonical signed digit" (CSD) form is used), and uses only 20% of the code space. Kripasagar, March 2008, "Efficient Micro Mathematics", Circuit Cellar, p.62, issue 212 Polynomial Root Finding Using the Horner scheme in combination with Newton's zero finding method it is possible to approximate the real roots of a polynomial. The algorithm is as follows. Given a polynomial of degree with zeros make some initial guess such that . Now follow the steps outline below. 1. Using Newton's method find the largest zero, of using the guess . 2. Use the Horner scheme to divide out to obtain . Return to step 1 but use the polynomial and the initial guess . These two steps are repeated until all real zeros are found for the polynomial. If the approximated zeros are not precise enough, the obtained values can be used as initial guesses for Newton's method but using the full polynomial rather than the reduced polynomials. Kress, Rainer, "Numerical Analysis", Springer, 1991, p.112, Example Root finding using the Horner Scheme Consider the polynomial, which can be expanded to, From the above we know that the largest root of this polynomial is 7 so we are able to make an initial guess of 8. Using Newton's method the first zero of 7 is found as shown in black in the figure to the right. Next is divided by to obtain, which is drawn in red in the figure to the right. Newton's method is used to find the largest zero of this polynomial with an initial guess of 7. The largest zero of this polynomial which corresponds to the second largest zero of the original polynomial is found at 3 and is circled in red. The degree 5 polynomial is now divided by to obtain, which is shown in yellow. The zero for this polynomial is found at 2 again using Newton's method and is circled in yellow. The Horner scheme is now used to obtain, which is shown in green and found to have a zero at -3. This polynomial is further reduced to, which is shown in blue and yields a zero of -5. The final root of the original polynomial may be found by either using the final zero as an initial guess for Newton's method, or by reducing and solving the linear equation. As can be seen, the expected roots of -8, -5, -3, 2, 3, and 7 were found. Octave Implementation The following Octave code was used in the example above to implement the Horner scheme. function [y b] = horner(a,x) % Input a is the polynomial coefficient vector, x the value to be evaluated at. % The output y is the evaluated polynomial and b the divided coefficient vector. b(1) = a(1); for i = 2:length(a) b(i) = a(i)+x*b(i-1); endfor y = b(length(a)); b = b(1:length(b)-1); end Application The Horner scheme is often used to convert between different positional numeral systems — in which case x is the base of the number system, and the ai coefficients are the digits of the base-x representation of a given number — and can also be used if x is a matrix, in which case the gain in computational efficiency is even greater. Efficiency Evaluation using the monomial form of a degree-n polynomial requires at most n additions and (n2 + n)/2 multiplications, if powers are calculated by repeated multiplication and each monomial is evaluated individually. (This can be reduced to n additions and 2n + 1 multiplications by evaluating the powers of x iteratively.) If numerical data are represented in terms of digits (or bits), then the naive algorithm also entails storing approximately 2n times the number of bits of x (the evaluated polynomial has approximate magnitude xn, and one must also store xn itself). By contrast, Horner's scheme requires only n additions and n multiplications, and its storage requirements are only n times the number of bits of x. Alternatively, Horner's scheme can be computed with n fused multiply-adds. Horner's scheme can also be extended to evaluate the first k derivatives of the polynomial with kn additions and multiplications . It has been shown that the Horner scheme is optimal, in the sense that any algorithm to evaluate an arbitrary polynomial must use at least as many operations. That the number of additions required is minimal was shown by Alexander Ostrowski in 1954; that the number of multiplications is minimal by Victor Pan, in 1966. When x is a matrix, the Horner scheme is not optimal. This assumes that the polynomial is evaluated in monomial form and no preconditioning of the representation is allowed, which makes sense if the polynomial is evaluated only once. However, if preconditioning is allowed and the polynomial is to be evaluated many times, then faster algorithms are possible. They involve a transformation of the representation of the polynomial. In general, a degree-n polynomial can be evaluated using only multiplications and n additions (see Knuth: The Art of Computer Programming, Vol.2). History Even though the algorithm is named after William George Horner, who described it in 1819, the method was already known to Isaac Newton in 1669, the Chinese mathematician Qin Jiushao in his Mathematical Treatise in Nine Sections in the 13th century, and even earlier to the Persian Muslim mathematician Sharaf al-Dīn al-Tūsī in the 12th century.

7,753 | Earthdawn | Earthdawn is a fantasy role-playing game, originally produced by FASA in 1993. In 1999 it was licensed to Living Room Games, which produced the Second Edition line. It is currently licensed to RedBrick Limited, a company that is producing the Classic or RedBrick's Earthdawn line (which is essentially an alternative second edition; see History below for more information). The game is similar to fantasy games like Dungeons & Dragons, but draws more inspiration from games like RuneQuest. The rules of the game are tightly bound to the underlying magical metaphysics, with the goal of creating a richer, more realistic fantasy world. Like many role-playing games from the nineties, Earthdawn focuses much of its detail on its setting, a province called Barsaive. History Starting in 1993, FASA released over 20 gaming supplements describing this universe; however, it closed down production of Earthdawn in January 1999. During that time several novels and short story anthologies set in the Earthdawn universe were also released. In late 1999, FASA granted Living Room Games a licensing agreement to produce new material for the game. The 2nd Edition did not alter the setting, though it did update the timeline to include events that took place in Barsaive. There were a few changes to the rules in the 2nd Edition; some classes were slightly different or altered abilities from the original. The changes were meant to allow for more rounded-out characters and better balance of play. Living Room Games last published in 2005, and they no longer have a license with FASA to publish Earthdawn material. In 2003, a second license was granted to RedBrick Limited, who are currently developing their own line based on the FASA products, while releasing the original FASA books in PDF form. The Earthdawn Player's Compendium and Earthdawn Gamemaster's Compendium are essentially an alternative second edition, but without a version designation (since the material is compatible anyway). Each book has over 500 pages, and summarizes much of what FASA published — not only the game mechanics, but also the setting, narrations, and stories. For example, each Discipline has its own chapter, describing it from the point of view of different adepts. Likewise, Barsaive gets a complete treatment, and the chapters contain a lot of log entries and stories in addition to the setting descriptions; the same applies also to Horrors and Dragons. Earthdawn Player's Compendium (RedBrick Limited) While RedBrick Limited tried to remain faithful to FASA's vision and also tried to keep the visual style, they revised almost everything, and introduced some new material to fill the gaps. RedBrick Limited also began publishing Earthdawn novels in 2007. On July 8th 2008, RedBrick announced a new line called Age of Legend 4e, a port of the Earthdawn setting for use with the Dungeons & Dragons 4th Edition rules. For the original line Redbrick announced a new 3rd Edition on March 15th 2009. In 1999 Pyramid magazine named Earthdawn as one of The Millennium's Most Underrated Games. Editor Scott Haring noted (referring to the FASA edition) that "Earthdawn had an original, inventive magic system (no mean trick given the hundreds of fantasy RPGs that came before), and a game world that gave you the classic "monsters and dungeons" sort of RPG experience, but made sense doing it." Setting In Barsaive, magic, like many things in nature, goes through cycles. As the magic level rises, it allows alien creatures called Horrors to cross from their distant, otherworldly dimension into our own. The Horrors come in an almost infinite variety -- from simple eating machines that devour all they encounter, to incredibly intelligent and cunning foes that feed off the negative emotions they inspire in their prey. In the distant past of Earthdawn'''s setting, an elf scholar discovered that the time of the Horrors was approaching, and founded the Eternal Library in order to discover a way to defeat them — or at the very least, survive them. The community that grew up around the library developed wards and protections against the Horrors, which they traded to other lands and eventually became the powerful Theran Empire, an extremely magically advanced civilization and the main antagonist of the Earthdawn setting. The peoples of the world built kaers, underground towns and cities, which they sealed with the Theran wards to wait out the time of the Horrors, which was called the Scourge. Theran wizards and politicians warned many of the outlying nations around Thera of the coming of the Horrors, offering the protection of the kaers to those who would pledge their loyalty to the Empire. Most of these nations agreed at first though some became unwilling to fulfill their end of the bargain after the end of the Scourge, wanting to have nothing to do with the bureaucratic nation run on political conflict and powered by slavery. After four hundred years of hiding, the Scourge ended, and the people emerged to a world changed by the Horrors. The player characters explore this new world, discovering lost secrets of the past, and fighting Horrors that remain. The primary setting of Earthdawn is Barsaive, a former province of the Theran Empire. Barsaive is a region of city-states, independent from the Therans since the dwarven Kingdom of Throal led a rebellion against their former overlords. The Theran presence in Barsaive has been limited to a small part of south-western Barsaive, based around the magical fortress of Sky Point and the city of Vivane. The setting of Earthdawn is the same world as Shadowrun, but takes place Millennia earlier. Races The setting of Earthdawn features several fantasy races for characters and NPCs: Dwarf - Dwarfs in Earthdawn are similar in appearance to the classic D&D or Tolkien dwarves. They are the predominant race in Barsaive, and the dwarf language is considered the common language. Their culture, especially of the dominant Throal Kingdom, can be considered more of a Renaissance-level culture than in most other fantasy settings, and form the main source of resistance to a return of Thera's rule in Barsaive. Elf - Elves in Earthdawn fit the common fantasy role-playing convention; they are tall, lithe, pointy-eared humanoids who prefer living in nature. Elves in Earthdawn naturally live a very long time; some are thought to be immortal. Such immortal Elves feature in many cross-pollinated storylines with Shadowrun. A subspecies of Earthdawn elves are called the Blood Elves. The blood elves rejected the Theran protective magic, and attempted their own warding spells. These wards failed, and a last-ditch ritual caused thorns to thrust through the skin of the blood elves. These ever-bleeding wounds caused constant pain, but the self-inflicted suffering was enough to protect the blood elves from the worst of the horrors. Human - Humans in Earthdawn are physically similar to humans in our own real world. Human adepts are granted a special Versatility talent to make them more mechanically appealing. Humans in Earthdawn are considered to be somewhat warlike in general outlook. Obsidiman - Obsidimen are a race of large, rock-based humanoids. They stand over 7 feet tall and weigh over 900 pounds. Their primary connection is to their Liferock, which is a large formation of stone within four hours of their place of birth. Obsidimen are loyal to the community around their Liferock, and eventually return to it. Obsidimen can live around 500 years away from their Liferock, and their ultimate lifespan is unknown, as they generally return to it and remain there. Due to their rocky nature and long lives, obsidimen are rather slow moving and deliberate in both speech and action, and can have difficulty understanding the smaller races' need for haste. However, if aroused by a threat to self, friend, or community, obsidimen are fearsome to behold. Ork - The ork race in Earthdawn is similar to other depictions of orks in fantasy role-playing. They are tribal, nomadic and often barbaric humanoids, with green, tan, beige or ebony skin. They are relatively short-lived, and as a result many attempt to leave a legacy marked by a memorable death - preferably one that leaves no corpse. Before the Scourge almost all orks were enslaved by other races. Troll - The troll race in Earthdawn is also similar to other fantasy role-playing depictions of trolls. They are very tall humanoids, with a hardened skin and horns. Socially, they form clans to which they are fiercely loyal. Troll clans often raid one another, and a significant subset of the troll race are crystal raiders, which command many of the airships of Barsaive. Other trolls, known as lowland trolls, have merged with mixed communities around Barsaive, although most retain the fierce cultural and personal pride of their less-civilized cousins. T'skrang - The t'skrang are lizard-like amphibian humanoids with long tails and a flair for dramatics. Many of them exhibit the behaviors and characteristics which are stereotypical to a "swashbuckler". T'skrang are often sailors, and many t'skrang families run ships up and down the rivers of Barsaive. A rare subrace of t'skrang, the k'stulaami, possess a flap of skin much like a flying squirrel, allowing them to glide. While k'stulaami can be born as a random mutation in any t'skrang line, they tend to congregate into communities filled with their own kind. Windling - The windlings are small, winged humanoids; similar to many depictions of fae creatures, they resemble small elves with insect-like wings. They have the ability to see into the astral plane, and are considerably luckier than the other races. Windlings are often somewhat mischievous, hedonistic, and eager for new experiences, and are culturally similar to the Kender of Krynn, but without the same kleptomaniacal tendencies. They have wings similar to those of a dragonfly and are one to two feet in height.

One of the most innovative ideas in Earthdawn is how magical items work. At first, most magical items work exactly like a mundane item of the same type. As a character searches for information about the item's history, performs certain tasks relating to that history, and spends legend points (the Earthdawn equivalent of experience points) to activate the item, he unlocks some of the magic in the item. As the character learns more about the item and its history, he can unlock more and more power within the item. Each magical item, therefore, is unique by virtue of its history and the scope of its powers. For example, one magical broadsword may have only 4 magical ranks and only increases the damage of the blade. On the other hand the legendary sword Purifier, has 10 magical ranks and grants its wielder numerous powers. Game mechanics The Earthdawn Companion 2nd Edition cover shows Throal, the capital of BarsaiveEarthdawn'' stands out from other tabletop RPGs with a unique approach to skill tests. Players wanting to perform an action determines their level or "step" for the skill, talent, or ability to be used. This step can then be looked up in a list of dice to be thrown. +Examples of steps Step Dice to be thrown 3 1D4 4 1D6 5 1D8 6 1D10 7 1D12 8 2D6 9 1D8 + 1D6 10 1D10+1D6 11 1D10+1D8 12 2D10 13 1D12+1D10 14 1D20+1D4 or 2D12 (Earthdawn Classic option) The result of each die is added (dice which reach their maximum value are thrown again, adding each maximum to the tally, along with the final result below maximum) and compared to a value decided by the game master/storyteller according to the difficulty of the task. This approach allows for impressively high scores with high level characters, yet leaves room for possible failure. This will sometimes make combat last longer than in other games.

7,754 | History_of_Islam | The Muslim history involves the history of the Islamic faith as a religion and as a social institution. The history of Islam began in Arabia with Muslim Prophet Muhammad's first recitations of the Qur'an in the 7th century. Like most world religions, the historical evolution of Islam had a significant impact on the political, economic, and military and beyond its primary geographic areas. Islam's historical development has affected both inside and outside the Islamic world. The concept of the Islamic world is useful in observing the different periods of human history; similarly useful is an understanding of the identification with a quasi-political community of believers, or ummah, on the part of Islam's practitioners down the centuries. Islamic culture encourages identification with a quasi-political community of believers or the ummah, and this principle has influenced the behavior of a number of players in history. The history of Islam is closely tied to the political, economic, and military. A century after the death of Muhammad, an Islamic empire extended from the Atlantic Ocean in the west to Central Asia in the east. The subsequent empires of the Umayyads, Abbasids, the Fatimids, the Mughals, the Safavids, and Ottomans were among the largest and most powerful in the world. The Islamic civilization gave rise to many centers of culture and science and produced notable scientists, astronomers, mathematicians, doctors, nurses and philosophers during the Golden Age of Islam. Technology flourished; there was much investment in economic infrastructure, such as irrigation systems and canals; and especially, the importance of reading the Qur'an produced a comparatively high level of literacy in the general populace. Later, in the eighteenth century and nineteenth century, many Islamic regions fell under the tutelage of European imperial powers. After the First World War, the remnants of the Ottoman empire were parcelled out as European protectorates. Since 1924, there has been no major widely-accepted claim to the caliphate (which had been last claimed by the Ottomans). Although affected by various ideologies such as communism, during much of the twentieth century, the Islamic identity and the dominance of Islam on political issues have arguably increased during the early twenty-first century. The fast-growing Western interests in Islamic regions, international conflicts and globalization have changed the influence of Islam on the world of the twenty-first century. http://www.islamonline.net/servlet/Satellite?c=Article_C&cid=1212925100226&pagename=Zone-English-ArtCulture%2FACELayout Milestones of Islamic History Origins According to the traditionalist view, the Qur'an began with revelations on Muhammad's divine revelations in AD 610. The verses of the Qur'an were written down and memorized during his life. Mecca was conquered by the Muslims in the year AD 630. In 628 the Meccan tribe of Quraish and the Muslim community in Medina had signed a truce called the Treaty of Hudaybiyya beginning a ten-year period of peace, which was broken when the Quraish and their allies, the tribe of Bakr, attacked the tribe of Khuza'ah, who were allies of the Muslims. Muhammad died in June 632. The Battle of Yamama was fought in December of the same year, between the forces of Rashidun Caliph Abu Bakr and Musailima. Early Caliphate After holy prophet Muhammad (peace be upon him) died, a series of Caliphs governed the Islamic State: Hazrat Abu Bakr Siddique, Hazrat Umar, Hazrat Uthman, Hazrat Ali and Hazrat Hasan. These first Caliphs are popularly known as the "Rashidun" or "rightly-guided" Caliphs in Sunni Islam. After the Rashidun, a series of Caliphates were established. Each caliphate developed its own unique laws based on the sharia. There were at times competing claims to the Sunni caliphate, and the Imams of Ismaili Shi'a Islam, descended from Ali and Muhammad PBUH through his daughter Hazrat Fatimah, set up their own caliphate which ruled the Fatimid Empire. Timeline Al-Rashidun - "The Rightly-Guided Khalifahs" Following Muhammad's death, a series of four Caliphs lead the Islamic Empire during this period. Starting with Abu Bakr, Omar, Uthman, and ending with Ali. Abbasids - "Islamic Golden Age" The gains of the Ummayad empire were consolidated upon when the Abbasid dynasty rose to power in 750, with the conquest of the Mediterranean islands including the Balearics and Sicily. The new ruling party had been instated on the wave of dissatisfaction propagated against the Ummayads, cultured mainly by the Abbasid revolutionary, Abu Muslim. Lewis (1993), p.84 Holt (1977a), p.105 Under the Abbasids, Islamic civilization flourished. Most notable was the development of Arabic prose and poetry, termed by The Cambridge History of Islam as its "golden age." Holt (1977b), pp.661-663 This was also the case for commerce and industry (considered a Muslim Agricultural Revolution), and the arts and sciences (considered a Muslim Scientific Revolution), which prospered, especially under the rule of Abbasid caliphs al-Mansur (ruled 754 — 775), Harun al-Rashid (ruled 786 — 809), al-Ma'mun (ruled 809 — 813), and their immediate successors. "Abbasid Dynasty", The New Encyclopedia Britannica (2005) Baghdad was made the new capital of the caliphate (moved from the previous capital, Damascus) due to the importance placed by the Abbasids upon eastern affairs in Persia and Transoxania. It was at this time however, that the caliphate showed signs of fracture and we witness the uprising of regional dynasties. Although the Ummayad family had been killed by the revolting Abbasids, one family member, Abd ar-Rahman I, was able to flee to Spain and establish an independent caliphate there in 756. In the Maghreb region, Harun al-Rashid appointed the Arab Aghlabids as virtually autonomous rulers, although they continued to recognise the authority of the central caliphate. Aghlabid rule was short lived, as they were deposed by the Shiite Fatimid dynasty in 909. By around 960, the Fatimids had conquered Abbasid Egypt, building a new capital there in 973 called "al-Qahirah" (meaning "the planet of victory", known today as Cairo). Similar was the case in Persia, where the Turkic Ghaznavids managed to snatch power from the Abbasids. "Islam", The New Encyclopedia Britannica (2005) Whatever temporal power of the Abbasids remained had eventually been consumed by the Seljuq Turks (a Muslim Turkish clan which had migrated into mainland Persia), in 1055. During this time, expansion continued, sometimes by military warfare, sometimes by peaceful proselytism. The first stage in the conquest of India began just before the year 1000. By some 200 (from 1193 — 1209) years later, the area up to the Ganges river had been conquered. In sub-Saharan West Africa, it was just after the year 1000 that Islam was established. Muslim rulers are known to have been in Kanem starting from sometime between 1081 to 1097, with reports of a Muslim prince at the head of Gao as early as 1009. The Islamic kingdoms associated with Mali reached prominence later, in the 13th century. During the Abbasid reign, Baghdad became one of the greatest cultural centers of the world. The Abbasids were said to be descendents of Abbas the uncle of Muhammad claiming that they were the 'messiah' or saviours of the people under the Ummayad rule. Abbasid caliphs Harun al-Rashid and Al-Mamun were great patrons of arts and sciences, and enabled these domains to flourish. Islamic philosophy also developed as the Shariah was codified, and the four Madhabs were established and built. This era also saw the rise of classical Sufism. The greatest achievement, however, was completion of the canonical collections of Hadith of Sahih Bukhari and others. Nasr (2003), p.121 Regional powers The Abbasids soon became caught within a three-way rivalry of Arabs, Persians and the immigrant Turks. Nasr (2003), p. 121-122 In addition, the cost of running a large empire became too great. Lapidus (1988), p.129 The political unity of Islam began to disintegrate. The Emirates, still recognizing the theoretical leadership of the caliphs, drifted into independence, and a brief revival of control was ended with the establishment of rival caliphates. Eventually the Abbasids ruled as puppets for the Buwayhid emirs. During this time, great advancements were made in the areas of astronomy, poetry, philosophy science and mathematics. The Fatimid Empire Al-Hakim Mosque, Cairo, Egypt The Fatimids had their origins in Ifriqiya (modern-day Tunisia and eastern Algeria). The dynasty was founded in 909 by, who legitimised his claim through descent from Muhammadby way of his daughter Fātima as-Zahra and her husband , the first Imām, hence the name al-Fātimiyyūn "Fatimid". Abdullāh al-Mahdi's control soon extended over all of central Maghreb, an area consisting of the modern countries ofMorocco, Algeria, Tunisia and Libya, which he ruled from Mahdia, his newly-built capital in Tunisia. The Fatimids entered Egypt in the late 900s, conquering the Ikhshidid dynasty and founding a new capital at al-Qāhira(Cairo) in 969. The name was a reference to the planet Mars, "The Subduer", which was prominent in the sky at the moment that city construction started. Cairo was intended as a royal enclosure for the Fatimid caliph and his army, though the actual administrative and economic capital of Egypt was in cities such as Fustat until 1169. After Egypt, the Fatimids continued to conquer the surrounding areas until they ruled from Tunisia to Syria and even crossed over into Sicily and southernItaly. Under the Fatimids, Egypt became the center of an empire that included at its peak North Africa, Sicily, Palestine,Lebanon, Syria, the Red Sea coast of Africa, Yemen and the Hejaz. Egypt flourished, and the Fatimids developed an extensive trade network in both the Mediterranean and the Indian Ocean. Their trade and diplomatic ties extended all the way to China and its Song Dynasty, which eventually determined the economic course of Egypt during the High Middle Ages. Unlike other governments in the area, Fatimid advancement in state offices was based more on merit than on heredity. Members of other branches of Islam, like the Sunnis, were just as likely to be appointed to government posts as Shiites. Tolerance was extended even to non-Muslims such as Christians and Jews, who occupied high levels in government based on ability. There were, however, exceptions to this general attitude of tolerance, most notably Al-Hakim bi-Amr Allah. The Fatimid palace was two parts. it used to be in the Khan el-Khalili area at Bin El-Quasryn street. The Iberian peninsula under the Umayyads and the Berber dynasties The interiors of the Alhambra in Granada, Spain decorated witharabesque designs. The Arabs, under the command of the Berber General Tarik ibn Ziyad, first began their conquest of southern Spain or al-Andalus in 711. A raiding party led by Tarik was sent to intervene in a civil war in the Visigothic kingdominHispania. Crossing the Strait of Gibraltar (named after the General), it won a decisive victory in the summer of 711 when the Visigothic king Roderic was defeated and killed on July 19 at the Battle of Guadalete. Tariq's commander, Musa bin Nusair quickly crossed with substantial reinforcements, and by 718 the Muslims dominated most of the peninsula. There are some later Arabic and Christian sources present an earlier raid by a certain Ṭārif in 710 and one, the Ad Sebastianum recension of the Chronicle of Alfonso III, refers to an Arab attack incited by Erwig during the reign of Wamba (672–80). and two reasonably large armies may have been in the south for a year before the decisive battle was fought. Collins (2004), 139. The rulers of Al-Andalus were granted the rank of Emir by the Umayyad Caliph Al-Walid I in Damascus. After theAbbasids came to power in the Middle East, some Umayyads fled to Muslim Spain to establish themselves there. By the end of the 10th century, the ruler Abd al-Rahman III took over the title of Emir of Córdoba(912-961). Hourani, pg.41 Soon after, the Umayyads went on developing a strengthened state with its capital as Córdoba. Al-Hakam II succeeded to the Caliphate after the death of his father Abd ar-Rahman III in 961. He secured peace with the Christian kingdoms of northern Iberia, and made use of the stability to develop agriculture through the construction of irrigation works. Economical development was also encouraged through the widening of streets and the building of markets. The rule of the Caliphate is known as the heyday of Muslim presence in the peninsula. The rule of the Umayyad Caliphate collapsed in 1031 due to political divisions and civil unrest during the rule of Hicham II who was ousted because of his indolence. Al-Andalus then broke up into a number of mostly independent states called taifa kingdoms (Arabic, Muluk al-ṭawā'if; English, Party kingdoms). The decomposition of the Caliphate into those petty kingdoms will then weaken the power of the Muslims in the Iberian Peninsula vis-à-vis the Christian kingdoms of the north. Some of the taifas such as that of Seville will consequently be forced to enter into alliances with the Christian princes and pay tributes in money to Castille. The Crusades Beginning in the 8th century C.E. the Christian kingdoms of Spain had begun the Reconquista aimed at retaking Al-Andalus from the Moors. In 1095, Pope Urban II, inspired by the perceived holy wars in Spain and implored by the eastern Roman emperor to help defend Christianity in the East, called for the First Crusade from Western Europe which captured Edessa, Antioch, Tripoli and Jerusalem. The Christian Kingdom of Jerusalem emerged and for a time controlled many holy sites of Islam. Saladin, however, restored unity within the Umma by defeating the Fatimids, and was then able to put an end to the Kingdom of Jerusalem in 1187 C.E. Other crusades were launched with at least the nominal intent to recapture the holy city and other holy lands, but hardly more was ever accomplished than the errant looting and occupation of Christian Constantinople, leaving the Eastern Roman, or Byzantine Empire severely weakened and ripe for later conquest. However, the crusaders did manage to weaken Muslim territories preventing them from further expansion into Christendom. The Mamluks In 1250 C.E., the short-lived Ayyubid dynasty (established by Saladin) was overthrown by slave regiments, and a new dynasty—the Mamluks—was born. The Mamluks, who were Turkic, soon expanded into Palestine, expelled the remaining Crusader states and repelled the Mongol attempt to invade Syria (see Battle of Ain Jalut). Thus they united Syria and Egypt for the longest period of time between the Abbasid and Ottoman empires (1250-1517). Hourani, pg.85 Islam in Africa The first continent outside of Arabia to have an Islamic history was Africa, particularly Abyssinia (modern day Ethiopia via modern day Eritrea). Islam in Maghreb This part of Islamic territory has had independent governments during most of Islamic history, with a number being of historical importance. The Idrisid dynasty were the first Arab rulers in the western Maghreb (Morocco), ruling from 788 to 985. The dynasty is named after its first sultan Idris I. The Almoravid dynasty a Berber dynasty from the Sahara that flourished over a wide area of North-Western Africa and the Iberian peninsula during the 11th century. Under this dynasty the Moorish empire was extended over present-day Morocco, Western Sahara, Mauritania, Gibraltar, Tlemcen (in Algeria) and a great part of what is now Senegal and Mali in the south, and Spain and Portugal in the north. The Almohad Dynasty or "the Unitarians," were a Berber Muslim religious power which founded the fifth Moorish dynasty in the 12th century, and conquered all northern Africa as far as Egypt, together withAl-Andalus. Islam in East Africa Islam in the East Africa can be dated back to the founding of the religion and the beginning with the hijra; in 615, when a group of Muslims were counseled by Muhammad to escape persecution in Mecca and travel to Abyssinia (an act known as the First migration to Abyssinia), which was ruled by, in Muhammad's estimation, a pious Christian king named al-Najashi (Negus, King of Abyssinia). Moreover, Islamic tradition states that the first muezzin Bilal al-Habeshi, one of the foremost companions of Muhammad, was from Abyssinia (Habasha). There were Islamic governments in Tanzania. The people of Zayd were allegedly the first Muslims to immigrate to East Africa. Islam came to east Africa mainly through trade routes. The African peoples that lived along these routes became converts due to the close contact they had with Arab traders in areas like Tabora, from which they affected the manners of Muslims, this leading to eventual conversion neither with encouragement nor discouragement by the Muslim Arabs. In pre-colonial East Africa, the structure of Islamic authority was held up through the Ulema (wanawyuonis, in Swahili language). Their base was mainly in Zanzibar. These leaders had some degree of authority over most of the Muslims in East Africa at this time; especially before territorial boundaries were established. This is because the majority of Muslims lived within the sphere of influence of the Sultanate in Zanzibar, the chief Qadi there being recognized for having the final religious authority. Islam in West Africa Usman dan Fodio after the Fulani War, found himself in command of the largest state in Africa, the Fulani Empire. Dan Fodio worked to establish an efficient government, one grounded in Islamic laws. Already aged at the beginning of the war, dan Fodio retired in 1815 passing the title of Sultan of Sokoto to his son Muhammed Bello. Islam in Asia Indian Subcontinent See also: Islam in India, Islam in Pakistan Islamic rule came to the region in the 8th century, when Muhammad bin Qasim conquered Sindh, (Pakistan). Muslim conquests were expanded under Mahmud and the Ghaznavids until the late twelfth century, when the Ghurids overran the Ghaznavids and extended the conquests in northern India. Qutb-ud-din Aybak, conquered Delhi in 1206 and began the reign of the Delhi Sultanates. In the fourteenth century, Alauddin Khilji extended Muslim rule south to Gujarat, Rajasthan and Deccan. Various other Muslim dynasties also formed and ruled across India from the 13th to the 18th century such as the Qutb Shahi and the Bahmani, but none rivalled the power and extensive reach of the Mughal Empire at its peak. China China was in fact not a Muslim country, but, it did contain exiled Muslims. Southeast Asia Islam reached the islands of Southeast Asia through Indian Muslim traders from Gujarat near the end of the 13th century. Soon, many Sufi missionaries translated classical Sufi literature from Arabic and Persian into Malay. Coupled with the composing of original Islamic literature in Malay, this led the way to the transformation of Malay into an Islamic language. Nasr (2003), p. 143 By 1292, when Marco Polo visited Sumatra, most of the inhabitants had converted to Islam. The Sultanate of Malacca was founded by Parameswara, a Srivijayan Prince in the Malay peninsula. Through trade and commerce, Islam spread to Borneo and Java, Indonesia. By the late 15th century, Islam had been introduced to the Philippines. As Islam spread, three main Muslim political powers emerged. Aceh, the most important Muslim power, was based firmly in Northern Sumatra. It controlled much of the area between Southeast Asia and India. The Sultunate also attracted Sufi poets. The second Muslim power was the Sultanate of Malacca on the Malay peninsula. The Sultanate of Demak was the third power, appearing in Java, where the emerging Muslim forces defeated the local Majapahit kingdom in the early 16th century. Bloom and Blair (2000), p. 226-230 Although the sultanate managed to expand its territory somewhat, its rule remained brief. Portuguese forces captured Malacca in 1511 under the naval general Afonso de Albuquerque. With Malacca subdued, the Aceh Sultanate and Brunei established themselves as centers of Islam in Southeast Asia. Brunei's sultanate remains intact even to this day. Mongol invasions The wave of Mongol invasions, which had initially commenced in the early 13th century under the leadership of Genghis Khan, marked a violent end to the Abbasid era. The Mongol Empire had spread rapidly throughout Central Asia and Persia: the Persian city of Isfahan had fallen to them by 1237. With the election of Khan Mongke in 1251, Mongol sights were set upon the Abbasid capital, Baghdad. Mongke's brother, Hulegu, was made the head of the Mongol Army assigned the task of subduing Baghdad. This was achieved at the Battle of Baghdad (1258), which saw the Abbasids overrun by the superior Mongol army. The last Abbasid caliph, al-Musta'sim, was captured and killed; and Baghdad was ransacked and subsequently destroyed. The cities of Damascus and Aleppo fell shortly afterwards, in 1260. Any prospective conquest of Egypt was temporarily delayed due to the death of Mongke at around the same time. With Mongol conquest in the east, the Ayyubid dynasty ruling over Egypt had been replaced by a man who was born prince struggled as a slave named Mamluks also known as Lion of Ain Jaloot in 1250. This had been done through the marriage between Shajar al-Durr, the widow of Ayyubid caliph al-Salih Ayyub, with the Mamluk general Aybak. Military prestige was at the center of Mamluk society, and it played a key role in the confrontations with the Mongol forces. After the assassination of Aybak, and the succession of Qutuz in 1259, the Mamluks challenged and decisively routed the Mongols at the Battle of Ain Jalut in late 1260. This signalled an adverse shift in fortunes for the Mongols, who were again defeated by the Mamluks at the Battle of Hims a few months later, and then driven out of Syria altogether. With this, the Mamluks were also able to conquer the last of the crusader territories. Three Muslim empires of the Early Modern Era In the 15th and 16th centuries three major Muslim empires were created: the aforementioned Ottoman Empire in much of the Middle East, the Balkans and Northern Africa; the Safavid Empire in Greater Iran; and the Mughul Empire in South Asia. These new imperial powers were made possible by the discovery and exploitation of gunpowder, and more efficient administration. Armstrong (2000) p. 116 By the end of the 19th century, all three had declined significantly, and by the early 20th century, with the Ottomans' defeat in World War I, the last Muslim empire collapsed. Mughal Empire The Mughal Empire was a product of various Central Asian invasions into the Indian subcontinent. It was founded by the Timurid prince Babur in 1526 with the destruction of the Delhi sultanate, with its capital in Agra. Babur's death some years later, and the indecisive rule of his son, Humayun, brought a degree of instability to Mughal rule. The resistance of the Afghani Sher Shah, through which a string of defeats had been dealt to Humayun, significantly weakened the Mughals. Just a year before his death, however, Humayun managed to recover much of the lost territories, leaving a substantial legacy for his son, the 13 year old Akbar (later known as Akbar the Great), in 1556. Under Akbar, consolidation of the Mughal Empire occurred through both expansion and administrative reforms. After Akbar, Jahangir and Shah Jahan came to power. Subsequently, Aurangazeb ruled vast areas include Afghanisthan, Pakistan, India and Bangladesh. Bloom and Blair (2000), p. 211-219 The empire ruled most of present-day India, Pakistan, Bangladesh and Afghanistan for several centuries, before it declined in the early 18th century, which led to India being divided into smaller kingdoms and princely states. The Mughal dynasty was eventually dissolved by the British Empire after the Indian rebellion of 1857. It left a lasting legacy on Indian culture and architecture. Famous buildings built by the Mughals, include: the Taj Mahal, the Red Fort, the Badshahi Mosque, the Lahore Fort, the Shalimar Gardens and the Agra Fort. During the empire's reign, Muslim communities flourished all over India, particularly in Gujarat, Bengal and Hyderabad. Various Sufi orders from Afghanistan and Iran were very active throughout the region. Consequently, more than a quarter of the population converted to Islam. Safavid Empire Shah Suleiman I and his courtiers, Isfahan, 1670. Painter is Ali Qoli Jabbador, and is kept at The St. Petersburg Institute of Oriental Studies in Russia, ever since it was acquired by Tsar Nicholas II. Note the two Georgian figures with their names at the top left. The Safavids () were an Iranian dynasty from Iranian Azarbaijan that ruled from 1501 to 1736, and which established Twelver Shi'a Islam as Iran's official religion and united its provinces under a single Iranian sovereignty, thereby reigniting the Persian identity. Although claiming to be the descendants of Ali ibn Abu Talib, the Safavids were originally Sunni (the name "Safavid" comes from a Sufi order called Safavi). Their origins go back to Firuz Shah Zarrinkolah, an Iranian local dignitary from Iran's north. During their rule, the Safavids recognized Twelver Shi'a Islam as the State religion, thus giving Iran a separate identity from its Sunni neighbours. In 1524, Tahmasp acceded to the throne, initiating a revival of the arts in the region. Carpet making became a major industry, gaining new importance in Iran's cities. But the finest of all artistic revivals was the commissioning of the Shahnama. The Shahnama was meant to glorify the reign of the Shah through artistic means. The two-volume copy contained 258 large paintings to illustrate the works of Firdawsi, a Persian poet. The Shah also prohibited the drinking of wine, forbade the use of hashish and ordered the removal of gambling casinos, taverns and brothels. Tahmasp's grandson, Shah Abbas I, also managed to increase the glory of the empire. Abbas restored the shrine of the eighth Twelver Shi'a Imam, Ali al-Ridha at Mashhad, and restored the dynastic shrine at Ardabil. Both shrines received jewelry, fine manuscripts and Chinese porcelains. Abbas also moved the empire's capital to Isfahan, revived old ports, and established thriving trade with the Europeans. Amongst Abbas's most visible cultural achievements was the construction of Naqsh-e Jahan Square ("Design of the World"). The plaza, located near a Friday mosque, covered , thus dwarfing Piazza San Marco and St. Peter's Square. Bloom and Blair (2000), p. 199-204 Ottoman Empire The Seljuk Turks fell apart rapidly in the second half of the 13th century, especially after the Mongol invasion of Anatolia. Holt (1977a), p.263 This resulted in the establishment of multiple Turkish principalities, known as beyliks. Osman I, the founder of the Ottoman dynasty, assumed leadership of one of these principalities (Söğüt) in 1281, succeeding his father Ertuğrul. Declaring an independent Ottoman emirate in 1299, Osman I led it to a series of consecutive victories over the Byzantine Empire. By 1331, the Ottomans had captured Nicaea, the former Byzantine capital, under the leadership of Osman's son and successor, Orhan I. Koprulu (1992), p.109 Victory at the Battle of Kosovo against the Serbs in 1389 then facilitated their expansion into Europe. The Ottomans were firmly established in the Balkans and Anatolia by the time Bayezid I ascended to power in the same year, now at the helm of a swiftly growing empire. Koprulu (1992), p.111 Further growth was brought to a sudden halt, as Bayezid I had been captured by Mongol warlord Timur (also known as "Tamerlane") in the Battle of Ankara in 1402, upon which a turbulent period known as the Ottoman Interregnum ensued. This episode was characterized by the division of the Ottoman territory amongst Bayezid I's sons, who submitted to Timurid authority. When a number of the territories recently conquered by the Ottomans regained independent status, potential ruin for the Ottoman Empire became imminent. However, the empire quickly recovered, as the youngest son of Bayezid I, Mehmed I, waged offensive campaigns against his ruling brothers, thereby reuniting Asia Minor and declaring himself the new Ottoman sultan in 1413. At around this time the naval fleet of the Ottomans developed considerably, such that they were able to challenge Venice, traditionally a naval power. Focus was also directed towards reconquering the Balkans. By the time of Mehmed I's grandson, Mehmed II (ruled 1444 — 1446; 1451 — 1481), the Ottomans felt strong enough to lay siege to Constantinople, the capital of Byzantium. A decisive factor in this siege was the use of firearms and large cannons introduced by the Ottomans (adapted from Europe and improved upon), against which the Byzantines were unable to compete. The Byzantine fortress finally succumbed to the Ottoman invasion in 1453, 54 days into the siege. Mehmed II, entering the city victorious, renamed it Istanbul. With its capital conceded to the Ottomans, the rest of the Byzantine Empire quickly disintegrated. The future successes of the Ottomans and later empires would depend heavily upon the exploitation of gunpowder. Armstrong (2000), p.116 In the early 16th century, the Shi'ite Safavid dynasty assumed control in Persia under the leadership of Shah Ismail I, upon the defeat of the ruling Turcoman federation Aq Qoyunlu (also called the "White Sheep Turkomans") in 1501. The Ottoman sultan Selim I quickly sought to repel Safavid expansion, challenging and defeating them at the Battle of Chaldiran in 1514. Selim I also deposed the ruling Mamluks in Egypt, absorbing their territories into the Ottoman Empire in 1517. Suleiman I (also known as Suleiman the Magnificent), Selim I's successor, took advantage of the diversion of Safavid focus to the Uzbeks on the eastern frontier and recaptured Baghdad, which had previously fallen under Safavid control. Despite this, Safavid power remained substantial, with their empire rivalling the Ottomans'. Suleiman I also advanced deep into Hungary following the Battle of Mohács in 1526 — reaching as far as the gates of Vienna thereafter, and signed a Franco-Ottoman alliance with Francis I of France against Charles V of the Roman Empire 10 years later. Suleiman I's rule (1520 — 1566) signified the height of the Ottoman Empire, after which it fell into a relative decline with the rapid industrialization of the European empires. www.muslimdecline.blogspot.com Wahhabism During the 18th century, Muhammad ibn Abd al Wahhab (1703 – 1792) led a religious movement (Wahhabism) in Najd (central Arabia) that sought to purify Islam. Wahhab wanted to return Islam to what he thought were its original principles as taught by the as-salaf as-saliheen (the earliest converts to Islam) and rejected what he regarded as corruptions introduced by bid‘ah (religious innovation) and Shirk (polytheism). He allied himself with the House of Saud, which eventually triumphed over the Rashidis to control Central Arabia, and led several revolts against the Ottoman empire. Initial success (the conquest of Mecca and Medina) was followed by ignominious defeat, then a resurgence which culminated in the creation of Saudi Arabia. The 20th century The modern age brought radical technological and organizational changes to Europe and Islamic countries found themselves less modern when compared to many western nations. Europe's state-based government and rampant colonization allowed the West to dominate the globe economically and forced Islamic countries to question change. Demise of the Ottoman Empire By the end of the 19th century, the Ottoman empire had declined due to internal conflict. Their decision to back Germany in World War I meant they shared the Central Powers' defeat in that war, which led directly to the overthrow of the Ottomans by Turkish nationalists led by Kemal Atatürk. Following World War I, its remnants were parceled out as European protectorates or spheres of influence. Ottoman successor states include today's Albania, Bosnia and Herzegovina, Bulgaria, Egypt, Greece, Iraq, Lebanon, Montenegro, Romania, Saudi Arabia, Serbia, Syria, Jordan, Turkey, other Balkan states, North Africa and the north shore of the Black sea. Berkshire Encyclopedia of World History, vol.4, p.1402 Many Muslim countries sought to adopt European political organization and nationalism began to emerge in the Muslim world. Countries like Egypt, Syria, and Turkey organized their governments with definable policies and sought to develop national pride amongst their citizens. Other places, like Iraq, were not as successful due to a lack of unity and an inability to resolve age-old prejudices between Muslim sects and against non-Muslims. Some Muslim countries, such as Turkey and Egypt, sought to separate Islam from the secular government. In other cases, such as Saudi Arabia, the new government brought out new religious expression in the re-emergence of the puritanical form of Sunni Islam known to its detractors as Wahhabism which found its way into the Saudi royal family. Partition of India The partition of India refers to the creation in August 1947 of the two sovereign states of India and Pakistan. The two nations were formed out of the former British Raj, including treaty states, when Britain granted independence to the area (see Undivided India). In particular, the term refers to the partition of Bengal and Punjab, the two main provinces of what would be Pakistan. In 1947, after the partition of India, Pakistan became the largest Islamic Country in the world (by population) and the tenth largest post-WWII state in the modern world. In 1971, after a bloody war of independence the Bengal part of Pakistan became an independent state called Bangladesh. Today, Pakistan is the second largest Islamic country in the world following Indonesia. Pakistan is presently the only nuclear power of the Muslim world. Arab-Israeli conflict The Arab-Israeli conflict spans about a century of political tensions and open hostilities. It involves the establishment of the modern State of Israel as a Jewish nation state, the consequent displacement of the Palestinian people, as well as the adverse relationship between the Arab nations and the state of Israel (see related Israeli-Palestinian conflict). Despite initially involving the Arab states, animosity has developed between other Muslim nations and Israel. Many countries, individuals and non-governmental organizations elsewhere in the world feel involved in this conflict for reasons such as cultural and religious ties with Islam, Arab culture, Christianity, Judaism, Jewish culture or for ideological, human rights, or strategic reasons. While some consider the Arab-Israeli conflict a part of (or a precursor to) a wider clash of civilizations between the Western World and the Arab or Muslim world, Causes of Anti-Americanism in the Arab World: A Socio-Political Perspective by Abdel Mahdi Abdallah (MERIA Journal. Volume 7, No. 4 - December 2003 Arab-Israeli Conflict: Role of religion (Israel Science and Technology) others oppose this view. Arab-American Psychiatrist Wafa Sultan: There is No Clash of Civilizations but a Clash between the Mentality of the Middle Ages and That of the 21st Century Animosity emanating from this conflict has caused numerous attacks on supporters (or perceived supporters) of each side by supporters of the other side in many countries around the world. Oil wealth Between 1953 and 1964, King Saud re-organized the government of the monarchy his father, Ibn Saud, had created. Saudi Arabia's new ministries included Communication (1953) Agriculture and Water (1953), Petroleum (1960), Pilgrimage and Islamic Endowments (1960), Labour and Social Affairs (1962) and Information (1963). He also put Talal, one of his many younger brothers (by 29 years his younger) in charge of the Ministry of Transport. In 1958-59, Talal proposed the formation of a National Council. As he proposed it, it would have been a consultative body, not a legislature. Still, he thought of it as a first step toward broader popular participation in the government. Talal presented this proposal to the king when the Crown Prince was out of the country. Saud simply forwarded the proposal to the ulama asking them whether a National Council was a legitimate institution in Islam. The idea seems to have died in committee, so to speak. It would be revived more than three decades later. A Consultative Council came into existence in 1992. Meantime, the Organization of Petroleum Exporting Countries came into existence in 1960. For the first decade or more of its existence, it was ineffectual in terms of increasing revenue for member nations. But it would have its day. Tension between Faisal and Saud continued to mount until a final showdown in 1964. Saud threatened to mobilize the Royal Guard against Faisal and Faisal threatened to mobilize the National Guard against Saud. It was Saud who blinked, abdicating and leaving for Cairo, then Greece, where he would die in 1969. Faisal then became King. The 1967 war had other effects. It effectively closed the Suez canal, it may have contributed to the revolution in Libya that put Muammar al-Gaddafi in power, and it led in May 1970 to the closure of the "tapline" from Saudi Arabia through Syria to Lebanon. These developments had the effect of increasing the importance of petroleum in Libya, which is a conveniently short (and canal-free) shipping distance from Europe. In 1970, it was Occidental Petroleum which constituted the first crack in the wall of oil company solidarity in dealing with the oil producing nations; specifically, in this case, with the demands for price increases from the new Qaddafi government. In October 1973, another war between Israel and its Muslim neighbors, known as the Yom Kippur War, got underway just as oil company executives were heading to Vienna, site of a planned meeting with OPEC leaders. OPEC had been emboldened by the success of Libya's demands anyway, and the war strengthened the unity of their new demands. The Arab defeats in the Six Day and 1973 Arab-Israeli wars triggered the 1973 oil crisis. In response to the emergency re-supply effort by the West that enabled Israel to defeat Egyptian and Syrian forces, the Arab world imposed the 1973 oil embargo against the United States and Western Europe. Faisal agreed that Saudi Arabia would use some of its oil wealth to finance the "front-line states," those that bordered Israel, in their struggle. The centrality of petroleum, the Arab-Israeli Conflict and political and economic instability and uncertainty remain constant features of the politics of the region. Two Iranian revolutions The Iranian Constitutional Revolution took place between 1905 and 1911. The revolution marked the beginning of the end of Iran's feudalistic society and led to the establishment of a parliament in Persia and restriction of the power of Shah (king). The first constitution of Iran was approved. But after the final victory of revolutionaries over Shah, the modernist and conservative blocks began to fight with each other. Then World War I took place and all of the combatants invaded Iran and weakened the government and threatened the independence of Iran. The system of constitutional monarchy created by the decree of Mozzafar al-Din Shah that was established in Persia as a result of the Revolution was weakened in 1925 with the dissolution of the Qajar dynasty and the ascension of Reza Shah Pahlavi to the throne. In 1979 the Iranian Revolution (also called "The Islamic Revolution" ) transformed Iran from a constitutional monarchy, under Shah Mohammad Reza Pahlavi, to a populist theocratic Islamic republic under the rule of Ayatollah Ruhollah Khomeini, a Shi`i Muslim cleric and marja. Following the Revolution, an Iranian referendum established the Islamic republic as a new government, and a new constitution was approved, electing Ruhollah Khomeini Supreme Leader of Iran. During the following two years, liberals, leftists, and Islamic groups fought with each other, and ultimately Islamics captured power. At the same time, the U.S., USSR, and most of the Arab governments of the Middle East feared that their dominance in the region was challenged by the new Islamic ideology, so they encouraged and supported Saddam Hussein to invade Iran, which resulted in the Iran-Iraq war. The 21st century Islam in Turkey Since the establishment of the Republic of Turkey in 1923, there has been a strong tradition of secularism in Turkey established and institutionalized by Atatürk's Reforms. Although the First Grand National Assembly of Turkey had rallied support from the population for the Independence War against the occupying forces on behalf of Islamic principles, Islam was gradually omitted from the public sphere after the Independence War. The principle of secularism was thus inserted in the Turkish Constitution as late as 1937. This legal action was assisted by stringent state policies against domestic Islamist groups and establishments to neutralize the strong appeal of Islam in Turkish society. Even though an overwhelming majority of the population, at least nominally, adheres to Islam in Turkey; the state, which was established with the Kemalist ideology has no official religion nor promotes any and it actively monitors the area between the religions using the Presidency of Religious Affairs. The Republic Protests were a series of peaceful mass rallies by Turkish secular citizens that took place in Turkey in 2007. The target of the first protest was the possible presidential candidacy of the Prime Minister Recep Tayyip Erdoğan, afraid that if elected President of Turkey Erdoğan would alter the Turkish secularist state "Secular rally targets Turkish PM", BBC News, April 14, 2007.

7,755 | Judah_the_Prince | Roman province of Judea.Rabbi Judah haNasi, (, pronounced Yehuda haNasi, "Judah the Prince"), also known as Rebbi and Rabbeinu HaKadosh (, "Our Holy Rabbi"), was a key leader of the Jewish community of Judea toward the end of the 2nd century CE, during the occupation by the Roman Empire. He is best known as the chief redactor and editor of the Mishnah. He was of the Davidic line, the royal line of King David, hence the title nasi, meaning prince Talmud Yerushalmi, quoted in Tosafos, Sanhedrin 5a. ; the title nasi was also used for presidents of the Sanhedrin. Mishna Chagiga 2:2. Biography The Galilee in late antiquity Judah haNasi was born in 135. According to the Midrash, he came into the world on the same day that Rabbi Akiva died a martyr's death. Midrash Genesis Rabbah 53; Midrash Eccl. Rabbah 1:10. The Talmud suggests that this was a result of Divine Providence: God had granted the Jewish people another leader of great stature to succeed Rabbi Akiva. His place of birth is unknown; nor is it recorded where his father, Shimon ben Gamliel II, sought refuge with his family during the persecutions under Hadrian. On the restoration of order in the Land of Israel, Usha became the seat of the academy and Judah spent his youth there. His father presumably gave him the same education that he himself had received, including Greek language. Sotah 49b. This knowledge of Greek enabled him to become the Jews' intermediary with the Roman authorities. He favored Greek as the language of the country over Syriac (Aramaic). ibid. It is said that in Judah's house, only Hebrew was spoken, and even the maids spoke it. Megillah 18a; Rosh Hashana 26b; Naz. 3a; 'Er. 53a. According to the Talmud (Avodah Zarah 10a-b), Judah haNasi was very wealthy and greatly revered in Rome. He had a close friendship with "Antoninus", possibly the Emperor Antoninus Pius, A. Mischcon, Abodah Zara, p.10a Soncino, 1988. Mischcon cites various sources, "SJ Rappaport... is of the opinion that our Antoninus is Antoninus Pius." Other opinions cited suggest "Antoninus" was Caracalla, Lucius Verus or Alexander Severus. who would consult Judah on various worldly and spiritual matters. The Talmud records the tradition that Judah haNasi was buried in the necropolis of Beit She'arim, in the Lower Galilee. Babylonian Talmud (Talmud Bavli), Tractate Bava Metzia 85a, Tractate Pesachim 49b; Jerusalem Talmud, Tractate Kelaim 9, 32a-b. Compiler of the Mishna According to Jewish tradition, God gave both the Written Law (Torah) and the Oral Law (additional laws and customs meant to be passed down from teacher to student) to Moses on Mount Sinai. For centuries, only the Torah appeared as a written text. Fearing that the oral traditions might be forgotten, Judah HaNasi undertook the mission of compiling them in what became known as the Mishna. The Mishna consists of 63 tractates codifying Jewish law, which are the basis of the Talmud. Talmudic legends Various stories are told about Judah haNasi to illustrate different aspects of his character. One of them begins by telling of a calf breaking free from being led to slaughter. According to the story, the calf tries to hide under Judah haNasi's robes, bellowing with terror, but he pushes the animal away, saying: "Go — for this purpose you were created." For this, Heaven inflicted upon him kidney stones, painful flatulence, and other gastric problems, saying, "Since he showed no pity, let us bring suffering upon him". The story remarks that when Judah haNasi prayed for relief, the prayers were ignored, just as he had ignored the pleas of the calf. Nevertheless, it goes on to describe him subsequently preventing his maid from violently expelling baby weasels from his house, on the basis that "It is written: 'His Mercy is upon all his works.'" For this, Heaven removes the gastric problems from him, saying, "Since he has shown compassion, let us be compassionate with him". Rabbi Judah HaNasi also said, "One who is ignorant of the Torah should not eat flesh" — possibly as a result of these experiences. Before the passing Rabbeinu HaKadosh said: ‘I need my sons!… Let the lamp continue to burn in its usual place; let the table be set in its usual place; let the bed be made in its usual place.” (Kesubbos 103a) Sefer Chassidim Sec. 1129. (Cf. Kesubbos 103a.) records that after his passing Rabbeinu HaKadosh used to visit his home, wearing Shabbos clothes, every Friday evening at dusk; he would recite Kiddush, and others would thereby discharge their obligation to hear Kiddush. One Friday night there was a knock at the door. "Sorry," said the maid, "I can't let you in just now because Rabbeinu HaKadosh is in the middle of kiddush." From then on Rabbeinu HaKadosh stopped coming, since he did not want his coming to become public knowledge.

7,756 | Franz_Schmidt | Franz Schmidt (December 22, 1874 – February 11, 1939) was an Austrian composer, cellist and pianist. Life Schmidt was born in Pressburg, in the Austro-Hungarian Empire (this is now Bratislava, Slovakia). His earliest teacher was his mother, an accomplished pianist, who gave him a systematic instruction in the keyboard works of J. S. Bach. He received a thorough foundation in theory from brother Felizian Moczik, the outstanding organist at the Franciscan church in Pressburg. Biographical note in insert to Amadeo recording AVRS 5004-5005. He studied piano briefly with Theodor Leschetizky, with whom he clashed. He moved to Vienna with his family in 1888, and studied at the Vienna Conservatory (composition with Robert Fuchs, cello with Ferdinand Hellmesberger and theory (the counterpoint class) with Anton Bruckner), graduating "with excellence" in 1896. He beat 13 other applicants in obtaining a post as cellist with the Vienna Court Opera Orchestra, with whom he played, often under Mahler, until 1914. Mahler habitually had all the cello solos played by Schmidt, even though Friedrich Buxbaum was actually the principal cellist. Schmidt was also in demand as a chamber musician, playing in the string quartet led by Arnold Schoenberg’s close friend Oskar Adler, who also became Schmidt’s doctor: Schmidt and Schoenberg maintained cordial relations despite their vast differences in style. In 1914 he took up a professorship (in piano) at the Vienna Conservatory, which had been recently renamed to Imperial Academy of Music and the performing arts. In 1925 he became Director of the Academy, and from 1927 to 1931 Rector. As teacher for piano, cello, counterpoint and composition at the Academy he trained numerous musicians, conductors and composers who later became famous. Among his best-known students are above all the pianist Friedrich Wührer and Alfred Rosé (son of Arnold Rosé, the legendary founder of the Rosé Quartet, Konzertmeister of the Vienna Philharmonic and brother-in-law of Gustav Mahler). Among the composers should be mentioned Theodor Berger, Marcel Rubin and Alfred Uhl. He received many tokens of the high esteem in which he was held, above all the Franz-Josef Order, and an Honorary Doctorate from the University of Vienna. This paragraph taken from German Wikipedia. Schmidt's private life was in stark contrast to the success of his distinguished professional career, and was overshadowed by tragedy. His first wife was, from 1919, confined in the Vienna mental hospital Am Steinhof, and three years after his death was murdered under the Nazi euthanasia laws. His daughter Emma died completely unexpectedly after the birth of her first child. Schmidt experienced a spiritual and physical breakdown after this, but achieved an artistic revival and resolution in his Fourth Symphony of 1933 (which he inscribed as "Requiem for my Daughter") and, especially, in his oratorio. His second marriage, to a successful young piano student, for the first time brought some desperately-needed stability into the private life of the artist, who was plagued by many serious health problems. This paragraph re-worked from German Wikipedia. Schmidt's worsening health forced his retirement from the Academy in early 1937. In the last year of his life Austria was brought into the German Reich by the Anschluss, and Schmidt was fêted by the Nazi authorities as the greatest living composer of the so-called Ostmark. He was given a commission to write a cantata entitled "The German Resurrection" which, after 1945, was taken by many as a reason to brand him as having been tainted by Nazi sympathy. However, Schmidt left this composition unfinished, and in summer and autumn 1938, a few months before his death, set it aside to devote himself to two other commissioned works for the one-armed pianist Paul Wittgenstein (brother of the philosopher Ludwig), for whom he had often composed: the Clarinet Quintet in A major and the solo Toccata in D minor. (Wittgenstein, being a Christian of Jewish descent, had been banned from public performance after the Anschluss and escaped to the U.S. in 1938.) Schmidt died on 11 February 1939. This paragraph from German Wikipedia. Œuvre (commentary) As a composer, Schmidt was slow to develop, but his reputation, at least in Austria, saw a steady growth from the late 1890s until his death in 1939. In his music, Schmidt continued to develop the Viennese classic-romantic traditions he inherited from Schubert, Brahms and his own master, Bruckner. He also takes forward the exotic ‘gypsy’ style of Liszt and Brahms. His works are monumental in form and firmly tonal in language, though quite often innovative in their designs and clearly open to some of the new developments in musical syntax initiated by Mahler and Schoenberg. Although Schmidt did not write a lot of chamber music, what he did write, in the opinion of such critics as Wilhelm Altmann, was important and of high quality. Although Schmidt's organ works may resemble others of the era in terms of length, complexity, and difficulty, they are forward-looking in being conceived for the smaller, clearer, classical-style instruments of the Orgelbewegung, which he advocated. Schmidt worked mainly in large forms, including four symphonies (1899, 1913, 1928 and 1933) and two operas: Notre Dame (1904-6) and Fredigundis (1916-21). A CD recording of Notre Dame has been available for many years, starring Dame Gwyneth Jones and James King. Fredigundis However no really adequate recording has been made of the far more interesting Fredigundis, for which there was but one "unauthorized" release in the early 1980s on the Voce Label of an Austrian Radio broadcast of a 1979 Vienna performance under the direction of Ernst Marzendorfer. In it, among numerous "royal fanfares," (Fredigundis held the French throne in the 8th Century) are some of Schmidt's most wonderful and glorious pages. A reasonable assumption would be that Jerome Kern was in the audience for its Berlin premier in 1922, because the hit song, "The Way You Look Tonight," featured in the film Swing Time, and which won the Academy Award for Best Original Song in 1936, bears a striking resemblance to the main theme from Act II of Fredigundis (the main difference being that the theme in Fredigundis, which goes through a whole series of transformations, is usually heard in march time). Credits went to Jerome Kern with lyrics by Dorothy Fields, the latter of whom claims to have heard the theme for the first time when Jerome Kern played it for her her on the piano, and there is little reason to doubt her. Kern himself may well have been unconscious of the borrowing. The New Grove states flatly that Fredigundis was a failure as Opera, but that is more likely attributable to the fact that Queen Fredigundis herself was anything but a "lovely lady," making the title character of Berg's Lulu seem like a princess in comparison. By the time Act III rolls around, things are pretty dismal and dark, and Schmidt is by this time harmonically on the threshold of Das Buch mit sieben Siegeln. Despite some possible faults with the libretto, this is musically a wonderful opera which deserves a modern and fair hearing. It is unfortunate that Marzendorfer's 1979 performance wasn't better recorded, because the performance-- offstage choruses and brass fanfares and all-- was veritably stupendous. The Book with Seven Seals See article The book with seven seals (oratorio) Schmidt's crowning achievement was the oratorio Das Buch mit sieben Siegeln (1935-37), a setting of passages from the Book of Revelation. His choice of subject was prophetic: with hindsight the work appears to foretell, in the most powerful terms, the disasters that were shortly to be visited upon Europe in the Second World War. Here his invention rises to a sustained pitch of genius. A narrative upon the text of the oratorio was provided by the composer. F. Schmidt, Einige Bemerkungen zum text des Oratoriums (Written for the original production). Reproduced in insert booklet to recording, Amadeo LP set AVRS 5004/5005 St, cond. Anton Lippe, Munich Philharmonic, Grazer Domchor, Franz Illenberger (organ), with Julius Patzak (Evangelist), Otto Wiener (Voice of God), Hanny Steffek, Hertha Töpper, Erich Majkut, Frederick Guthrie. Recorded Stephaniesaal, Graz, January 1962. Schmidt's oratorio stands in the Austro-German tradition stretching back to the time of Bach and Handel. He was the first to write an oratorio fully on the subject of the Book of Revelation (as opposed to a Last Judgement in a Requiem like that of Verdi). Far from glorifying its subject, it is a mystical contemplation, a horrified warning, and a prayer for salvation. The premiere was held in Vienna on 15 June 1938, with the Vienna Symphony Orchestra under Oswald Kabasta: the soloists were Rudolf Gerlach (John), Erika Rokyta, Enid Szantho, Anton Dermota, Josef von Manowarda and with Franz Schütz at the organ. This work provided the only actual model for the fictional oratorio Apocalypsis cum Figuris described by Thomas Mann in his 1947 novel Doctor Faustus. Mann invests his fictional oratorio and its composer with the demonic conflicts in German society leading to the catastrophe of the Nazi ideology and the Second World War. That was indeed the context in which Schmidt's oratorio appeared, but his private character and artistic motivations (as distinct from the society in which they existed) are not to be construed, in reality or in sum, through the lens of Mann's literary formula, which was assembled from a very wide array of Germanic themes and personalities. Symphonies Schmidt is generally, if erroneously, regarded as a conservative composer (such labels rest upon yet-to-be-resolved aesthetic/stylistic arguments), but the rhythmic subtlety and harmonic complexity of much of his music belie this. His music is modern without being modernist, combining a reverence for the great Austro-German lineage of composers with very personal innovations in harmony and orchestration. The considerable technical accomplishment of his music ought to compel respect, but he seems to have fallen between two stools: his works are too complex for the conservatively-minded, yet too obviously traditional for the avant-garde (they are also notoriously difficult to perform). Since the 1970s his music has enjoyed a modest revival which looks set to continue as it is rediscovered and re-evaluated. Symphony No. 1 in E Major. Written in 1896 at age 22. The scherzo of this precociously accomplished symphony (which shows a mature absorption of Bruckner and Richard Strauss) is especially noteworthy, while in the Finale, Schmidt demonstrates his contrapuntal skills. Symphony No. 2 in E Flat Major. Written in 1913 in a style strongly reminiscent of Strauss and Reger. This is Schmidt's largest symphony in terms of duration and employs a huge orchestra. The central movement (of three) is a highly ingenious set of variations, which are grouped to suggest the characters of slow movement and scherzo. The complex scoring of this magnificent symphony renders it a considerable challenge for most orchestras. Symphony No. 3 in A Major. A sunny, melodic work in the Schubert vein (although its lyricism and superb orchestration do much to conceal the fact that it is one of the composer's most harmonically advanced works). Winner of the Austrian section of the 1928 International Columbia Graphophone Competition, it enjoyed some popularity at the time (1928). Symphony No. 4 in C Major.Written in 1933, this is the best-known work of his entire oeuvre. The composer called it "A requiem for my daughter". It begins with a long 23-bar melody on an unaccompanied solo trumpet (which returns at the symphony's close, "transfigured" by all that has intervened). The Adagio is an immense ABA ternary structure. The first A is an expansive threnody on solo cello (Schmidt's own instrument) whose seamless lyricism predates Strauss's Metamorphosen by more than a decade (its theme is later adjusted to form the scherzo of the symphony); the B section is an equally expansive funeral march (deliberately referencing Beethoven's Eroica in its texture) whose dramatic climax is marked by an orchestral crescendo culminating in a gong and cymbal crash (again, a clear allusion to similar climaxes in the later symphonies of Bruckner, and followed by what Harold Truscott has brilliantly described as a "reverse climax", leading back to a repeat of the A section). Schmidt and Nazism Schmidt's premiere of Das Buch mit sieben Siegeln was made much of by the Nazis (who had annexed Austria shortly before in the Anschluss), and Schmidt was seen (according to a report by Georg Tintner) to give the Nazi salute. His conductor Kabasta was apparently an enthusiastic Nazi who, being prohibited from conducting in 1946 during de-nazification, committed suicide. These facts long placed Schmidt's posthumous reputation under a cloud. His lifelong friend and colleague Oskar Adler, who fled the Nazis in 1938, wrote afterwards that Schmidt was never a Nazi and never anti-semitic but was extremely naïve about politics. Hans Keller gave similar endorsement. Regarding Schmidt's political naivety, Michael Steinberg, in his magisterial book, The Symphony, tells of Schmidt's recommending Variations on a Hebrew Theme by his student Israel Brandmann to a musical group associated with the proto-Nazi German National Party. Most of Schmidt's principal musical friends were Jews, and they benefited from his generosity. Schmidt's last work, the cantata "German Resurrection," was composed to a Nazi text. As one of the most famous living Austrian composers, Schmidt was well-known to Hitler and received this commission after the Anschluss. He left it partially completed, to be completed later by Robert Wagner. Already seriously ill, Schmidt worked instead on other compositions such as a piano quintet. His failure to complete the cantata may be a further indication that he was not committed to the Nazi cause.

7,757 | Chuck_Jones | Charles Martin "Chuck" Jones (September 21, 1912 – February 22, 2002) was an American animator, cartoon artist, screenwriter, producer, and director of animated films, most memorably of Looney Tunes and Merrie Melodies shorts for the Warner Bros. Cartoons studio. He directed many of the classic short animated cartoons starring Bugs Bunny, Daffy Duck, the Road Runner & Wile E. Coyote, Pepé Le Pew and the other Warners characters, including Duck Amuck, One Froggy Evening and What's Opera, Doc? (all three of which were later inducted into the National Film Registry) and Jones' famous "Hunting Trilogy" of Rabbit Fire, Rabbit Seasoning, and Duck! Rabbit! Duck! (1951–1953). After his career at Warner Bros. ended in 1962, Jones started Sib Tower 12 Productions and began producing cartoons for Metro-Goldwyn-Mayer, including a new series of Tom & Jerry shorts and the television adaptation of Dr. Seuss' How the Grinch Stole Christmas!. He later started his own studio, Chuck Jones Productions, which created several one-shot specials, and periodically worked on Looney Tunes related works. Early life Jones was born in Spokane, Washington, and later moved with his parents and three siblings to the Los Angeles, California area. In his autobiography, Chuck Amuck, Jones credits his artistic bent to circumstances surrounding his father, who was an unsuccessful businessman in California in the 1920s. His father, Jones recounts, would start every new business venture by purchasing new stationery and new pencils with the company name on them. When the business failed, his father would quietly turn the huge stacks of useless stationery and pencils over to his children, requiring them to use up all the material as fast as possible. Armed with an endless supply of high-quality paper and pencils, the children drew constantly. Later, in one art school class, the professor gravely informed the students that they each had 100,000 bad drawings in them that they must first get past before they could possibly draw anything worthwhile. Jones recounted years later that this pronouncement came as a great relief to him, as he was well past the 200,000 mark, having used up all that stationery. Jones and several of his siblings went on to artistic careers. After graduating from Chouinard Art Institute, Jones held a number of low-ranking jobs in the animation industry, including washing cels at the Ub Iwerks studio and assistant animator at the Walter Lantz studio. While at Iwerks, he met a cel painter named Dorothy Webster, who would later become his wife. Warner Bros. Chuck Jones joined Leon Schlesinger Productions, the independent studio that produced Looney Tunes and Merrie Melodies for Warner Bros., in 1933 as an assistant animator. In 1935, he was promoted to animator, and assigned to work with new Schlesinger director Tex Avery. There was no room for the new Avery unit in Schlesinger's small studio, so Avery, Jones, and fellow animators Bob Clampett, Virgil Ross, and Sid Sutherland were moved into a small adjacent building they dubbed "Termite Terrace". When Clampett was promoted to director in 1937, Jones was assigned to his unit; the Clampett unit were briefly assigned to work with Jones' old employer, Ub Iwerks, when Iwerks subcontracted four cartoons to Schlesinger in 1937. Jones became a director (or "supervisor", the original title for an animation director in the studio) himself in 1938 when Frank Tashlin left the studio. Jones' first cartoon was The Night Watchman, which featured a cute kitten who would later evolve into Sniffles the mouse. Many of Jones' cartoons of the 1930s and early 1940s were lavishly animated, but audiences and fellow Schlesinger staff members found them lacking in genuine humor. Often slow-moving and overbearing with "cuteness", Jones' early cartoons were an attempt to follow in the footsteps of Walt Disney's shorts (especially with such cartoons as Tom Thumb in Trouble and the Sniffles cartoons). Jones finally broke away from traditional animation conventions with the cartoon The Dover Boys in 1942. Jones credits this cartoon as the film where he "learned how to be funny." The Dover Boys is also one of the first uses of Stylized animation in American film, breaking away from the more realistic animation styles influenced by the Disney Studio. This was also the period where Jones created many of his lesser-known characters, including Charlie Dog, Hubie and Bertie, and The Three Bears. Despite their relative obscurity today, the shorts starring these characters represent some of Jones' earliest work that was strictly intended to be funny. During the World War II years, Jones worked closely with Theodor Geisel (also known as Dr. Seuss) to create the Private Snafu series of Army educational cartoons. Private Snafu comically educated soldiers on topics like spies and laziness in a more risque way than general audiences would have been used to at the time. Jones would later collaborate with Seuss on a number of adaptations of Seuss' books to animated form, most importantly How the Grinch Stole Christmas! in 1966. A still from What's Opera, Doc?. Jones hit his stride in the late 1940s, and continued to make his best-regarded works through the 1950s. Jones-created characters from this period includes Claude Cat, Marc Antony and Pussyfoot, Charlie Dog, Michigan J. Frog, and his three most popular creations, Pepe LePew, the Road Runner, and Wile E. Coyote. The Road Runner cartoons, in addition to the cartoons that are considered his masterpieces (all written and conceived by Michael Maltese), Duck Amuck, One Froggy Evening, and What's Opera, Doc? are today hailed by critics as some of the best cartoons ever made. The staff of the Jones' Unit A were as important to the success of these cartoons as Jones himself. Key members included writer Maltese, layout artist/background designer/co-director Maurice Noble, animator and co-director Abe Levitow, and animators Ken Harris and Ben Washam. In 1950, Jones and Maltese began working on Rabbit Fire, a short that changed Daffy Duck's personality forever. They decided to make him a totally different character; instead of the wacky, comic relief character he had been, they turned Daffy into a vain, egomaniacal prima donna wanting to steal the spotlight from Bugs Bunny. Of his versions of Bugs and Daffy, Chuck Jones has said, "Bugs is who we want to be. Daffy is who we are." Jones remained at Warner Bros. throughout the 1950s, except for a brief period in 1953 when Warner closed the animation studio. During this interim, Jones found employment at Walt Disney Pictures, where he teamed with Ward Kimball for a four month period of uncredited work on Sleeping Beauty (1959). Upon the reopening of the Warner animation department, Jones was rehired & reunited with most of his unit. In the early-1960s, Jones and his wife Dorothy wrote the screenplay for the animated feature Gay Purr-ee. The finished film would feature the voices of Judy Garland, Robert Goulet and Red Buttons as cats in Paris, France. The feature was produced by UPA, and directed by his former Warner collaborator, Abe Levitow. Jones moonlit to work on the film, since he had an exclusive contract with Warner Bros. UPA completed the film and made it available for distribution in 1962; it was picked up by Warner Bros. When Warner discovered that Jones had violated his exclusive contract with them, they fired him. An Interview with Chuck Jones Not long after, Jack Warner closed the studio's animation shop (Jones frequently claimed, including in the aforementioned autobiography, that this happened because Warner finally learned they weren't making Mickey Mouse cartoons). Jones on his own With business partner Les Goldman, Jones started an independent animation studio Sib Tower 12 Productions, bringing on most of his unit from Warner Bros., including Maurice Noble and Michael Maltese. In 1963, Metro-Goldwyn-Mayer contracted with Sib Tower 12 to have Jones and his staff produce new Tom and Jerry cartoons. In 1964, Sib Tower 12 was absorbed by MGM and was renamed MGM Animation/Visual Arts. Jones' animated short film The Dot and the Line: A Romance in Lower Mathematics won the 1965 Oscar for Best Animated Short. Jones also directed the classic animated short "The Bear That Wasn't". As the Tom and Jerry series wound down (it would be discontinued in 1967), Jones moved on to television. In 1966, he produced and directed the TV special How the Grinch Stole Christmas!, featuring the voice and facial features of Boris Karloff. Jones continued to work on TV specials such as Horton Hears a Who! (1970), but his main focus during this time was producing the feature film The Phantom Tollbooth, which did lukewarm business when MGM released it in 1970. Jones co-directed 1969's The Pogo Special Birthday Special, based on the Walt Kelly comic strip, and voiced the characters of Porky Pine and Bun Rab. MGM closed the animation division in 1970, and Jones once again started his own studio, Chuck Jones Productions. He produced a Saturday morning children's TV series for the American Broadcasting Company called The Curiosity Shop in 1971. In 1973, he produced an animated version of the George Selden book The Cricket in Times Square, and would go on to produce two sequels. His most notable work during this period was three animated TV adaptations of short stories from Rudyard Kipling's The Jungle Book: Mowgli's Brothers, The White Seal and Rikki-Tikki-Tavi. Jones resumed working with Warner Bros. in 1976 with the animated TV adaptation of The Carnival of the Animals with Bugs Bunny and Daffy Duck. Jones also produced the 1979 movie The Bugs Bunny/Road Runner Movie which was a compilation of Jones' best theatrical shorts; Jones produced new Road Runner shorts for The Electric Company series and Bugs Bunny's Looney Christmas Tales (1979), and even newer shorts were made for Bugs Bunny's Bustin' Out All Over (1980). From 1977-1978 Jones wrote & drew the syndicated comic strip Crawford (also known as Crawford & Morgan) for the Chicago Tribune-NY News Syndicate. In 1978, Jones' wife Dorothy died; three years later, he married Marian Dern, the writer of the comic strip Rick O'Shay. Later years Through the 1980s and 1990s, Jones was painting cartoon and parody art, sold through animation galleries by his daughter's company, Linda Jones Enterprises. He was also creating new cartoons for the Internet based on his new character, Thomas Timberwolf. He made a cameo appearance in the 1984 film Gremlins and directed the Bugs Bunny/Daffy Duck animated sequences that bookend Gremlins 2: The New Batch (1990). Jones also directed animated sequences various features such as a lengthy sequence in the 1992 film Stay Tuned and a shorter one seen at the start of the 1993 film Mrs. Doubtfire. Jones was not a fan of much contemporary animation, terming most of it, especially television cartoons such as those of Hanna-Barbera, "illustrated radio". In 1988, Jones contributed to the creation of London's Museum of the Moving Image by spending several days working high on scaffolding creating a chase sequence directly onto the high walls of the museum. Jones was a historical authority as well as a major contributor to the development of animation throughout the 20th century. He received an honorary degree from Oglethorpe University in 1993. In his later years, Jones became the most vocal alumnus of the Termite Terrace studio, frequently giving lectures, seminars, and working to educate newcomers in the animation field. Many of his principles, therefore, found their way back into the mainstream animation consciousness, and can be seen in films such as Cats Don't Dance, The Rip Borsley Show, The Emperor's New Groove and Lilo & Stitch. For his contribution to the motion picture industry, Jones has a star on the Hollywood Walk of Fame at 7011 Hollywood Blvd. Jones, whose work had been nominated eight times over his career for an Oscar (winning thrice, for For Scent-imental Reasons, So Much for So Little, and The Dot and the Line), received an Honorary Academy Award in 1996 by the Board of Governors of the Academy of Motion Picture Arts and Sciences, for "the creation of classic cartoons and cartoon characters whose animated lives have brought joy to our real ones for more than half a century." At that year's awards show, Robin Williams, a self-confessed "Jones-aholic," presented the Honorary award to Jones, calling him "The Orson Welles of cartoons." Jones' final Looney Tunes cartoon was From Hare to Eternity in 1996/1997, which starred Bugs Bunny and Yosemite Sam, with Greg Burson voicing Bugs. The cartoon was dedicated to Friz Freleng, who had passed on in 1995. Jones did produce a few more Looney Tunes-based and non-related cartoons, a noticeable one being Chariots of Fur, his final Road Runner cartoon, in 1994. Jones, the last surviving animation director from the "Termite Terrace" days of the WB cartoons, died of heart failure in 2002. He was cremated after the funeral service and his ashes were scattered at sea. Cartoon Network aired a 30-second segment with black dots tracing Jones' portrait with the words "We'll miss you - Cartoon Network." fading in on the right-hand side. After his death, the Looney Tunes cartoon Daffy Duck for President, based on the book that Jones had written and using Jones' style for the characters, originally scheduled to be released in 2000, was released in 2004.

7,758 | Lift_(force) | Airbus A380 taking off during the Paris Air Show in 2007. A fluid flowing past the surface of a body exerts a force on it. If the fluid is air, the force is called an aerodynamic force. Lift is defined to be the component of this force which is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is is defined to be the component of the aerodynamic force parallel to the flow direction. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Clancy, L.J., Aerodynamics, Section 5.2 Lift is commonly associated with the wing of a fixed-wing aircraft, although lift is also generated by propellers; helicopter rotors; rudders, sails and keels on sailboats; hydrofoils; wings on auto racing cars; wind turbines and other streamlined objects. While common meanings of the word "lift" suggest that lift opposes gravity, lift can be in any direction. When an aircraft is flying straight and level (cruise) all of the lift opposes gravity. However, when an aircraft is climbing, descending, or banking in a turn, for example, the lift is tilted with respect to the vertical and the lift is greater than, or less than, the weight of the aircraft. Clancy, L.J., Aerodynamics, Section 14.6 Lift may also be entirely downwards in some aerobatic manoeuvres, or on the wing on a racing car. In this last case, the term downforce is often used. Non-streamlined objects such as bluff bodies and plates (not parallel to the flow) may also generate lift when moving relative to the fluid. This lift may be steady, or it may oscillate due to vortex shedding. Interaction of the object's flexibility with the vortex shedding may enhance the effects of fluctuating lift and cause vortex-induced vibrations. Description of lift on an airfoil Lift is generated in accordance with the fundamental principles of physics. The most relevant physics reduce to three principles: Newton's laws of motion, especially Newton's second law which relates the net force on an element of air to its rate of momentum change, conservation of mass, including the common assumption that the airfoil's surface is impermeable for the air flowing around, and an expression relating the fluid stresses (consisting of pressure and shear stress components) to the properties of the flow. In the last principle, the pressure depends on the other flow properties, such as its mass density, through the (thermodynamic) equation of state, while the shear stresses are related to the flow through the air's viscosity. Application of the viscous shear stresses to Newton's second law for an airflow results in the Navier–Stokes equations. But in many instances approximations suffice for a good description of lifting airfoils: in large parts of the flow viscosity may be neglected. Such an inviscid flow can be described mathematically through the Euler equations, resulting from the Navier-Stokes equations when the viscosity is neglected. The Euler equations for a steady and inviscid flow can be integrated along a streamline, resulting in Bernoulli's equation. The particular form of Bernoulli's equation found depends on the equation of state used. At low Mach numbers, compressibility effects may be neglected, resulting in an incompressible flow approximation. In incompressible and inviscid flow the Bernoulli equation is just an integration of Newton's second law—in the form of the description of momentum evolution by the Euler equations—along a streamline. Explaining lift while considering all of the principles involved is a complex task and is not easily simplified. As a result, there are numerous different explanations of lift with different levels of rigour and complexity. For example, there is an explanation based directly on Newton’s laws of motion; and an explanation based on Bernoulli’s principle. Neither of these explanations is incorrect, but each appeals to a different audience. In order to explain lift as it applies to an airplane wing, consider the incompressible flow around a 2-D, symmetric airfoil at positive angle of attack in a uniform free stream. Instead of considering the case where an airfoil moves through a fluid as seen by a stationary observer, it is equivalent and simpler to consider the picture when the observer follows the airfoil and the fluid moves past it. The explanation presented first is a summary of the most scientifically complete and accepted explanation; alternative and generally more accessible explanations follow below. Lift in an established flow Streamlines around a NACA 0012 airfoil at moderate angle of attack. If one takes the experimentally observed flow around an airfoil as a starting point, then lift can be explained in terms of pressures using Bernoulli's principle (which can be derived from Newton's second law) and conservation of mass. The image to the right shows the streamlines over a NACA 0012 airfoil computed using potential flow theory, a simplified model of the real flow. The flow approaching an airfoil can be divided into two streamtubes, which are defined based on the area between two streamlines. By definition, fluid never crosses a streamline in a steady flow; hence mass is conserved within each streamtube. One streamtube travels over the upper surface, while the other travels over the lower surface; dividing these two tubes is a dividing line (the stagnation streamline) that intersects the airfoil on the lower surface, typically near to the leading edge. The stagnation streamline leaves the airfoil at the sharp trailing edge, a feature of the flow known as the Kutta condition. In calculating the flow shown, the Kutta condition was imposed as an initial assumption; the justification for this assumption is explained below. The upper stream tube constricts as it flows up and around the airfoil, a part of the so-called upwash. From the conservation of mass, the flow speed must increase as the stream tube area decreases. The area of the lower stream tube increases, causing the flow inside the tube to slow down. It is typically the case that the air parcels traveling over the upper surface will reach the trailing edge before those traveling over the bottom. From Bernoulli's principle, the pressure on the upper surface where the flow is moving faster is lower than the pressure on the lower surface. The pressure difference thus creates a net aerodynamic force, pointing upward and downstream to the flow direction. The component of the force normal to the free stream is considered to be lift; the component parallel to the free stream is drag. In conjunction with this force by the air on the airfoil, by Newton's third law, the airfoil imparts an equal-and-opposite force on the surrounding air that creates the downwash. Measuring the momentum transferred to the downwash is another way to determine the amount of lift on the airfoil. , pp. 68–69 and pp. 153–155. Flowfield formation In attempting to explain why the flow follows the upper surface of the airfoil, the situation gets considerably more complex. It is here that many simplifications are made in presenting lift to various audiences, some of which are explained after this section. Consider the case of an airfoil accelerating from rest in a viscous flow. Lift depends entirely on the nature of viscous flow past certain bodies : in inviscid flow (i.e. assuming that viscous forces are negligible in comparison to inertial forces), there is no lift without imposing a net circulation, the proper amount of which can be determined by applying the Kutta condition. In a viscous flow like in the physical world, however, the lift and other properties arise naturally as described here. When there is no flow, there is no lift and the forces acting on the airfoil are zero. At the instant when the flow is “turned on”, the flow is undeflected downstream of the airfoil and there are two stagnation points on the airfoil (where the flow velocity is zero): one near the leading edge on the bottom surface, and another on the upper surface near the trailing edge. The dividing line between the upper and lower streamtubes mentioned above intersects the body at the stagnation points. Since the flow speed is zero at these points, by Bernoulli's principle the static pressure at these points is at a maximum. As long as the second stagnation point is at its initial location on the upper surface of the wing, the circulation around the airfoil is zero and, in accordance with the Kutta–Joukowski theorem, there is no lift. The net pressure difference between the upper and lower surfaces is zero. The effects of viscosity are contained within a thin layer of fluid called the boundary layer, close to the body. As flow over the airfoil commences, the flow along the lower surface turns at the sharp trailing edge and flows along the upper surface towards the upper stagnation point. The flow in the vicinity of the sharp trailing edge is very fast and the resulting viscous forces cause the boundary layer to accumulate into a vortex on the upper side of the airfoil between the trailing edge and the upper stagnation point. Clancy, L.J., Aerodynamics, Figure 4.7 This is called the starting vortex. The starting vortex and the bound vortex around the surface of the wing are two halves of a closed loop. As the starting vortex increases in strength the bound vortex also strengthens, causing the flow over the upper surface of the airfoil to accelerate and drive the upper stagnation point towards the sharp trailing edge. As this happens, the starting vortex is shed into the wake, Clancy, L.J., Aerodynamics, Figure 4.8 and is a necessary condition to produce lift on an airfoil. If the flow were stopped, there would be a corresponding "stopping vortex". Despite being an idealization of the real world, the “vortex system” set up around a wing is both real and observable; the trailing vortex sheet most noticeably rolls up into wing-tip vortices. The upper stagnation point continues moving downstream until it is coincident with the sharp trailing edge (as stated by the Kutta condition). The flow downstream of the airfoil is deflected downward from the free-stream direction and, from the reasoning above in the basic explanation, there is now a net pressure difference between the upper and lower surfaces and an aerodynamic force is generated. Alternative explanations for the generation of lift Many alternative explanations for the generation of lift by an airfoil have been put forward, of which a few are presented here. Most of them are intended to explain the phenomenon of lift to a general audience. Although the explanations may share features in common with the explanation above, additional assumptions and simplifications may be introduced. This reduces the validity of an alternative explanation to a limited sub-class of lift generating conditions, or does not allow a quantitative analysis. Several theories introduce assumptions which proved to be wrong, like the equal transit-time theory. Equal transit-time An illustration of the equal transit-time theory. An explanation of lift frequently encountered in basic or popular sources is the equal transit-time theory. Equal transit-time states that because of the longer path of the upper surface of an airfoil, the air going over the top must go faster in order to catch up with the air flowing around the bottom. Such that the parcels of air that are divided at the leading edge, and travel above and below an airfoil must rejoin when they reach the trailing edge. However, this is not accurate “This is simply not true.” Anderson, John D. Jr, Introduction to Flight, p.355 (5th edition), McGraw-Hill ISBN 0-07-282569-3 and the fact that this is not generally the case can be readily observed. A visualization of the typical retarded flow over the lower surface of the wing and the accelerated flow over the upper surface starts at 5:29 in the video. Although it is true that the air moving over the top of a wing generating lift does move faster, there is no requirement for equal transit time. In fact the air moving over the top of an airfoil generating lift is always moving much faster than the equal transit theory would imply. Coandă effect In a limited sense, the Coandă effect refers to the tendency of a fluid jet to stay attached to an adjacent surface that curves away from the flow, and the resultant entrainment of ambient air into the flow. The effect is named for Henri Coandă, the Romanian aerodynamicist who exploited it in many of his patents. One of the first known uses was in his patent for a high-lift device that used a fan of gas exiting at high speed from an internal compressor. This circular spray was directed radially over the top of a curved surface shaped like a lens to decrease the pressure on that surface. The total lift for the device was caused by the difference between this pressure and that on the bottom of the craft. Two aircraft, the Antonov An-72 and An-74 "Coaler", use the exhaust from top-mounted jet engines flowing over the wing to enhance lift, as do the Boeing YC-14 and the McDonnell Douglas YC-15. The effect is also used in high-lift devices such as a blown flap. More broadly, some consider the effect to include the tendency of any fluid boundary layer to adhere to a curved surface, not just the boundary layer accompanying a fluid jet. It is in this broader sense that the Coandă effect is used by some to explain lift. Jef Raskin , for example, describes a simple demonstration, using a straw to blow over the upper surface of a wing. The wing deflects upwards, thus supposedly demonstrating that the Coandă effect creates lift. This demonstration correctly demonstrates the Coandă effect as a fluid jet (the exhaust from a straw) adhering to a curved surface (the wing). However, the upper surface in this flow is a complicated, vortex-laden mixing layer, while on the lower surface the flow is quiescent. The physics of this demonstration are very different from that of the general flow over the wing. The usage in this sense is encountered in some popular references on aerodynamics. In the aerodynamics field, the Coandă effect is commonly defined in the more limited sense above and viscosity is used to explain why the boundary layer attaches to the surface of a wing. In terms of a difference in areas When a fluid flows relative to a solid body, the body obstructs the flow, causing some of the fluid to change its speed and direction in order to flow around the body. The obstructive nature of the solid body causes the streamlines to move closer together in some places, and further apart in others. When fluid flows past a 2-D cambered airfoil at zero angle of attack, the upper surface has a greater area (that is, the interior area of the airfoil above the chordline) than the lower surface and hence presents a greater obstruction to the fluid than the lower surface. This asymmetry causes the streamlines in the fluid flowing over the upper surface to move closer together than the streamlines over the lower surface. As a consequence of mass conservation, the reduced area between the streamlines over the upper surface results in a higher velocity than that over the lower surface. The upper streamtube is squashed the most in the nose region ahead of the maximum thickness of the airfoil, causing the maximum velocity to occur ahead of the maximum thickness. In accordance with Bernoulli's principle, where the fluid is moving faster the pressure is lower, and where the fluid is moving slower the pressure is greater. The fluid is moving faster over the upper surface, particularly near the leading edge, than over the lower surface so the pressure on the upper surface is lower than the pressure on the lower surface. The difference in pressure between the upper and lower surfaces results in lift. Newton's laws: Lift and the deflection of the flow The direct relationship between the lift force and the downward deflection of the air by the wing helps to obtain an insight into the phenomenon of lift. This explanation relies on the second and third of Newton's laws of motion: The net force on an object is equal to its rate of momentum change and To every action there is an equal and opposite reaction. , Vol. 1, §10–1 and §10–2. For a fluid, the momentum density is equal to mass density multiplied by the flow velocity. Now consider an airfoil in straight flight at constant speed, and observe the airflow from the frame of reference in which the velocity of the airfoil is zero. John D. Anderson explains the relationship between lift and downwash as follows: "The wing deflects the airflow such that the mean velocity vector behind the wing is canted slightly downward (…). Hence, the wing imparts a downward component of momentum to the air; that is, the wing exerts a force on the air, pushing the flow downward. From Newton's third law, the equal and opposite reaction produces a lift." This explanation of lift was used in the 1944 book Stick and Rudder by aviation writer Wolfgang Langewiesche: "… the wing keeps the airplane up by pushing the air down." "The main fact of all heaver-than-air flight is this: the wing keeps the airplane up by pushing the air down." In: Consequently, the lift is directly related to the deflection of the flow field behind the airfoil. More precisely: the lift is directly related to the flux of the vertical component of momentum through a vertical plane behind the airfoil. This vertical plane is perpendicular to the oncoming flow direction, in a frame of reference moving with the airfoil. One may be tempted to think that lift can be explained along this line of reasoning, saying that lift on the airfoil is caused by the downward deflection of the airflow. However, this is a misinterpretation of Newton's laws. One can just as well argue that the downwash behind the airfoil is an effect of the lift force: according to Newton's third law the upward lift is accompanied by a downward force on the air. This latter force is pushing the air down, which results in a downward deflection of the velocity vectors behind the airfoil. Newton's laws of motion are not sufficient to explain lift. Also a force model is needed. To see this, consider for example an object under the influence of gravity: Newton's law of gravity is required in addition to his laws of motion, in order to be able to describe the object's motion. , Vol. 1, §9–4 and §12–1. So also for air flows a force model is needed, relating flow properties to resulting stresses. Primarily, in the case of aerodynamics, this is an equation of state describing the air pressure dependence on the other flow characteristics. In case of the flow around an airfoil at low Mach numbers, the usual force model results from the incompressible flow approximation. Then the mass density is constant and the pressure is such that it constraints the flow to be isochoric — air parcels are of constant volume as they move along with the flow. Methods to determine lift on an airfoil Lift coefficient If the lift coefficient for a wing at a specified angle of attack is known (or estimated using a method such as thin-airfoil theory), then the lift produced for specific flow conditions can be determined using the following equation: where L is lift force, ρ is air density v is true airspeed, A is planform area, and is the lift coefficient at the desired angle of attack, Mach number, and Reynolds number Kutta–Joukowski theorem Lift can be calculated using potential flow theory by imposing a circulation. It is often used by practicing aerodynamicists as a convenient quantity in calculations, for example thin-airfoil theory and lifting-line theory. The circulation is the line integral of the velocity of the air, in a closed loop around the boundary of an airfoil. It can be understood as the total amount of "spinning" (or vorticity) of air around the airfoil. The section lift/span can be calculated using the Kutta–Joukowski theorem: where is the air density, is the free-stream airspeed. Kelvin's circulation theorem states that circulation is conserved. Clancy, L.J., Aerodynamics, Section 7.27 There is conservation of the air's angular momentum. When an aircraft is at rest, there is no circulation. The challenge when using the Kutta–Joukowski theorem to determine lift is to determine the appropriate circulation for a particular airfoil. In practice, this is done by applying the Kutta condition, which uniquely prescribes the circulation for a given geometry and free-stream velocity. A physical understanding of the theorem can be observed in the Magnus effect, which is a lift force generated by a spinning cylinder in a free stream. Here the necessary circulation is induced by the mechanical rotation acting on the boundary layer, causing it to induce a faster flow around one side of the cylinder and a slower flow around the other. The asymmetric distribution of airspeed around the cylinder then produces a circulation in the outer inviscid flow. Clancy, L.J., Aerodynamics, Sections 4.5 and 4.6 Pressure integration The force on the wing can be examined in terms of the pressure differences above and below the wing, which can be related to velocity changes by Bernoulli's principle. The total lift force is the integral of vertical pressure forces over the entire wetted surface area of the wing: Anderson, John D. (2004), Introduction to Flight, Section 5.7 (5th edition), McGraw-Hill. ISBN 0-07-282569-3 where: L is the lift, A is the wing surface area p is the value of the pressure, n is the normal unit vector pointing into the wing, and k is the vertical unit vector, normal to the freestream direction. The above lift equation neglects the skin friction forces, which typically have a negligible contribution to the lift compared to the pressure forces. By using the streamwise vector i parallel to the freestream in place of k in the integral, we obtain an expression for the pressure drag Dp (which includes induced drag in a 3D wing). If we use the spanwise vector j, we obtain the side force Y. One method for calculating the pressure is Bernoulli's equation, which is the mathematical expression of Bernoulli's principle. This method ignores the effects of viscosity, which can be important in the boundary layer and to predict friction drag, which is the other component of the total drag in addition to Dp. The Bernoulli principle states that the sum total of energy within a parcel of fluid remains constant as long as no energy is added or removed. It is a statement of the principle of the conservation of energy applied to flowing fluids. A substantial simplification of this proposes that as other forms of energy changes are inconsequential during the flow of air around a wing and that energy transfer in/out of the air is not significant, then the sum of pressure energy and speed energy for any particular parcel of air must be constant. Consequently, an increase in speed must be accompanied by a decrease in pressure and vice-versa. It should be noted that this is not a causational relationship. Rather, it is a coincidental relationship, whatever causes one must also cause the other as energy can neither be created nor destroyed. It is named for the Dutch-Swiss mathematician and scientist Daniel Bernoulli, though it was previously understood by Leonhard Euler and others. Bernoulli's principle provides an explanation of pressure difference in the absence of air density and temperature variation (a common approximation for low-speed aircraft). If the air density and temperature are the same above and below a wing, a naive application of the ideal gas law requires that the pressure also be the same. Bernoulli's principle, by including air velocity, explains this pressure difference. The principle does not, however, specify the air velocity. This must come from another source, e.g., experimental data. In order to solve for the velocity of inviscid flow around a wing, the Kutta condition must be applied to simulate the effects of inertia and viscosity. The Kutta condition allows for the correct choice among an infinite number of flow solutions that otherwise obey the laws of conservation of mass and conservation of momentum. Lift forces on bluff bodies Flow separation and a Von Kármán vortex street behind a circular cylinder. The flow is from the right to the left. Part of the cylinder can be seen at the right edge of the image. Two locations of flow separation from the cylinder are clearly visible. The flow around bluff bodies may also generate lift, besides a strong drag force. For instance, the flow around a circular cylinder generates a Kármán vortex street: vortices being shed in an alternating fashion from each side of the cylinder. The oscillatory nature of the flow is reflected in the fluctuating lift force on the cylinder, whereas the mean lift force is negligible. The lift force frequency is characterised by the dimensionless Strouhal number, which depends (among others) on the Reynolds number of the flow. For a flexible structure, this oscillatory lift force may induce vortex-induced vibrations. Under certain conditions — for instance resonance or strong spanwise correlation of the lift force — the resulting motion of the structure due to the lift fluctuations may be strongly enhanced. Such vibrations may pose problems, even collapse, in man-made tall structures like for instance industrial chimneys, if not properly taken care of in the design.

7,759 | Recapitulation_theory | The theory of recapitulation, also called the biogenetic law or embryological parallelism, and often expressed as "ontogeny recapitulates phylogeny", was put forward by Étienne Serres in 1824–26 as what became known as the "Meckel-Serres Law" which attempted to provide a link between comparative embryology and a "pattern of unification" in the organic world. It was supported by Étienne Geoffroy Saint-Hilaire and became a prominent part of his ideas which suggested that past transformations of life could have had environmental causes working on the embryo, rather than on the adult as in Lamarckism. These naturalistic ideas led to disagreements with Georges Cuvier. It was widely supported in the Edinburgh and London schools of higher anatomy around 1830, notably by Robert Edmond Grant, but was opposed by Karl Ernst von Baer's ideas of divergence, and attacked by Richard Owen in the 1830s. In 1866, the German zoologist Ernst Haeckel proposed that the embryonal development of an individual organism (its ontogeny) followed the same path as the evolutionary history of its species (its phylogeny). This theory, in the highly elaborate and deterministic form advanced by Haeckel, has, since the early twentieth century, been refuted on many fronts. Haeckel's drawings used artistic licence, his theory was associated with Lamarckism, it was quite clearly wrong in supposing that embryos passed through the adult stages of more primitive life-forms, it ignored organs such as teeth which are "held over" to a late developmental stage, and it was used by Haeckel to promote the supremacy of the white European male. However, the basic idea of recapitulation is still widespread - Stephen Jay Gould's first book (Ontogeny and Phylogeny) begins by declaring that many scientific professionals believe, privately and informally, that there is "something in" the notion. Stephen Jay Gould, Phylogeny and Ontogeny, Harvard 1985 (See Evolutionary developmental biology) Haeckel's theory Romanes's 1892 copy of Ernst Haeckel's controversial embryo drawings (this version of the figure is often attributed incorrectly to Haeckel). Richardson and Keuck, "Haeckel’s ABC of evolution and development," p. 516 Haeckel formulated his theory as "Ontogeny recapitulates phylogeny". The notion later became simply known as the recapitulation (OED: 'a summing up or brief repetition') theory. Ontogeny is the growth (size change) and development (shape change) of an individual organism; phylogeny is the evolutionary history of a species. Haeckel's recapitulation theory claims that the development of advanced species passes through stages represented by adult organisms of more primitive species. Otherwise put, each successive stage in the development of an individual represents one of the adult forms that appeared in its evolutionary history. For example, Haeckel proposed that the gill slits (pharyngeal arches) in the neck of the human embryo represented an adult "fishlike" developmental stage as well as signifying a fishlike ancestor. Embryonic pharyngeal arches, the invaginations between the gill pouches or pharyngeal pouches, open the pharynx to the outside. Such gill pouches appear in all tetrapod animal embryos: in mammals, the first gill bar (in the first gill pouch) develops into the lower jaw (Meckel's cartilage), the malleus and the stapes. At a later stage, all gill slits close, only the ear remaining open. But these embryonic pharyngeal arches could not at any stage carry out the same function as the gills of an adult fish. Haeckel produced several embryo drawings that often overemphasized similarities between embryos of related species. These found their ways into many biology textbooks, and into popular knowledge. Rejection Modern biology rejects the literal and universal form of Haeckel's theory. Although humans are generally understood to share ancestors with other taxa, stages of human embryonic development are not functionally equivalent to the adults of these shared common ancestors. In other words, no cleanly defined and functional "fish", "reptile" and "mammal" stages of human embryonal development can be discerned. Moreover, development is nonlinear. For example, during kidney development, at one given time, the anterior region of the kidney is less developed (nephridium) than the posterior region (nephron). Modern biology does recognize numerous connections between ontogeny and phylogeny, and explains them using evolutionary theory without recourse to Haeckel's specific views, and considers them as supporting evidence for that theory. Historical influence Although Haeckel's specific form of recapitulation theory is now discredited among biologists, it had a strong influence on social and educational theories of the late 19th century. English philosopher Herbert Spencer was one of the most energetic promoters of evolutionary ideas to explain many phenomena. He compactly expressed the basis for a cultural recapitulation theory of education in the following claim: Kieran Egan, The educated mind: How Cognitive Tools Shape Our Understanding., p.27 (University of Chicago Press, 1997, Chicago. ISBN 0-226-19036-6) The maturationist theory of G. Stanley Hall was based on the premise that growing children would recapitulate evolutionary stages of development as they grew up and that there was a one-to-one correspondence between childhood stages and evolutionary history, and that it was counterproductive to push a child ahead of its development stage. The whole notion fit nicely with other social Darwinist concepts, such as the idea that "primitive" societies needed guidance by more advanced societies, i.e. Europe and North America, which were considered by social Darwinists as the pinnacle of evolution. An early form of the law was devised by the 19th-century Estonian zoologist Karl Ernst von Baer, who observed that embryos resemble the embryos, but not the adults, of other species. Modern observations Generally, if a structure pre-dates another structure in evolutionary terms, then it also appears earlier than the other in the embryo. Species which have an evolutionary relationship typically share the early stages of embryonal development and differ in later stages. Examples include: The backbone, the common structure among all vertebrates such as fish, reptiles and mammals, appears as one of the earliest structures laid out in all vertebrate embryos. The cerebrum in humans, the most sophisticated part of the brain, develops last. If a structure vanished in an evolutionary sequence, then one can often observe a corresponding structure appearing at one stage during embryonic development, only to disappear or become modified in a later stage. Examples include: Whales, which have evolved from land mammals, don't have legs, but tiny remnant leg bones lie buried deep in their bodies. During embryonal development, leg extremities first occur, then recede. Similarly, whale embryos have hair at one stage (like all mammalian embryos), but lose most of it later. The common ancestor of humans and monkeys had a tail, and human embryos also have a tail at one point; it later recedes to form the coccyx. The swim bladder in fish presumably evolved from a sac connected to the gut, allowing the fish to gulp air. In most modern fish, this connection to the gut has disappeared. In the embryonal development of these fish, the swim bladder originates as an outpocketing of the gut, and is later disconnected from the gut.

7,760 | Geography_of_Nauru | Nauru is a tiny phosphate rock island located in the South Pacific Ocean south of the Marshall Islands in Oceania. It is only 53 km south of the Equator at coordinates . Nauru is one of the three great phosphate rock islands in the Pacific Ocean — the others are Banaba (Ocean Island) in Kiribati and Makatea in French Polynesia. Its land area is 21 km² and it has a 30 km coastline. Maritime claims are a 200 nautical mile (370 km) exclusive fishing zone, and a 12 nautical mile (22 km) territorial sea. The climate is tropical with a monsoonial rainy season from November to February. A sandy beach rises to the fertile ring around raised coral reefs. The raised phosphate plateau ('Topside') takes up the central portion of the island. The highest point is 200 ft (61 m) above sea level along the plateau rim. Nauru's only economically significant natural resources are phosphates, formed from guano deposits by seabirds over many thousands of years, and fisheries Annual Report Part 1: Information on Fisheries, Research and Statistics: Republic of Nauru. Working Paper 17 of the 4th Scientific Committee of the Western and Central Pacific Fisheries Commission. WCPFC 2008. , particularly for tuna. Due to being surrounded by corals and sandy beaches, the island houses no natural harbours, nor any rivers or substantial lakes. Geology of Nauru An aerial image of Nauru in 2002 from the U.S. Department of Energy's Atmospheric Radiation Measurement Program. Regenerated vegetation covers 63% of land that was mined. Republic of Nauru. 1999. Climate Change Response Under the United Nations Framework Convention on Climate Change URL Accessed 2006-05-03 Nauru is positioned in the Nauru Basin of the Pacific Ocean, on a part of the Pacific Plate that formed at a mid oceanic ridge at 132 Ma. From mid Eocene (35mya) to Oligocene times a submarine volcano built up over a hotspot, and formed a seamount composed of basalt. The seamount is over 4300 meters high. This hotspot was simultaneous with a major Pacific Plate reorganisation. The volcano was eroded to sealevel and a coral atoll grew on top to a thickness of about 500 meters. Coral near the surface has been dated from 5 Mya to 0.3 Mya. The original limestone has been dolomitised by magnesium from sea water. The coral was raised above sea level about 30 meters, and is now a dolomite limestone outcrop which was eroded in classic karst style into pinnacles up to 20 meters high. To at least a depth of 55 meters below sea level, the limestone has been dissolved forming cavities, sinkholes and caves. Holes on the topside of the island were filled up by a phosphate layer up to several meters thick. Anibare Bay was formed by the underwater collapse of the east side of the volcano. Buada Lagoon was formed by solution of the limestone when the sea level was lower, followed by collapse. Nauru is moving at 104 mm per year to the north west along with the Pacific Plate. Freshwater can be found in Buada lagoon, and also in some brackish ponds at the escarpment base in Ijuw and Anabar in the northeast. There is an underground lake in Moqua Cave in the southeast of the island. Environmental issues Periodic droughts, limited natural fresh water resources (roof storage tanks collect rainwater, but mostly dependent on a single, aging desalination plant) Extreme soil conditions are caused by high alkalinity, high phosphate levels and low potassium. Iron, manganese, copper, molybdenum and zinc are rendered unavailable to plants. Combined with thin or damaged soils this causes low fertility. Intensive phosphate mining during the past 90 years has left the central 90% of Nauru a wasteland and threatens limited remaining land resources. Nauru is party to the international environmental agreements on biodiversity, climate change, desertification, law of the sea and marine dumping.

7,761 | Bursa | Bursa (historically also known as Prussa, Greek: Προύσα, and later as Brusa) is a city in northwestern Turkey and the seat of Bursa Province. With a population of 2,562,828 (2007), it is Turkey's fourth largest city, as well as one of the most industrialized and culturally charged metropolitan centers in the country. Bursa is settled on the north-west slopes of the Mount Uludağ in the South of Marmara Region. It is bordered by The Marmara Sea and Yalova on the north, Kocaeli and Sakarya on the north-east, Bilecik on the east and Kütahya and Balıkesir on the south. The city is frequently cited as "Yeşil Bursa" (meaning "Green Bursa") in a reference to the parks and gardens located across its urban tissue, as well as to the vast forests in rich variety that extend in its surrounding region. The city is synonymous with the mountain Uludağ which towers behind the city core and which is also a famous ski resort. The mausoleums of early Ottoman sultans are located in Bursa and the numerous edifices built throughout the Ottoman period constitute the city's main landmarks. The surrounding fertile plain, its thermal baths, several interesting museums, notably a rich museum of archaeology, and a rather orderly urban growth are further principal elements that complete Bursa's overall picture. Karagöz and Hacivat shadow play characters were historic personalities who lived and are buried in Bursa. Bursa is also home to some of the most famous Turkish dishes, especially candied chestnuts and İskender kebap. Its peaches are also well-renowned. Among its depending district centers, İznik, historic Nicaea, is especially notable for its long history and important edifices. Bursa is home to Uludağ University, and its population attains one of the highest overall levels of education in Turkey. It has traditionally been a pole of attraction and of refuge for immigration into Turkey from the Balkans, in sizable waves at times until quite recently . History Bursa City on Miniature Style Bursa in 1890 The earliest known site at this location was Cius, which Philip V of Macedonia granted to the Bithynian king Prusias I in 202 BC, for his help against Pergamum and Heraclea Pontica (modern Karadeniz Ereğli). Prusias renamed the city after himself, as Prusa. It was later a major city, located on the westernmost end of the famous Silk Road, and was the capital of the Ottoman Empire following its capture from the shrinking Byzantine Empire in 1326. After the city was captured from the Byzantine Empire, many structures were built especially when it was the capital city of the Ottoman Empire. The capture of Didymoteichon and Edirne in 1365 brought that city to the fore as well, but Bursa remained an important administrative and commercial center even after it lost its status as the sole capital. Shortly after it was taken by the Ottomans they developed a school of theology at Bursa . This school attracted Muslim scholars from throughout the Middle East and continued to function after the capital had been moved elsewhere. During the Ottoman rule, Bursa was the source of most royal silk products. Aside from the local production, it imported raw silk from Iran, and occasionally China, and was the 'factory' for the kaftans, pillows, embroidery and other silk products for the royal palaces up through the 17th century. Another traditional occupation is knife making and, historically, horse carriage building. Nowadays one can still find hand-made knives as well as other products in rich variety produced by artisans, but instead of carriages, there is a big automobile industry. Bursa sits on a geologic fault like most of Turkey. The city was partially leveled by strong earthquakes coupled with fires and was rebuilt after each time. Being on the first degree earthquake zone, it was widely affected by the earthquakes which took place in 1855 and 1905. Economy A view from the city center Zafer Plaza shopping center Bursa is the center of Turkey's automobile industry . Factories of motor vehicle producers like FIAT and Renault, as well as automotive parts producers like Bosch have been active in the city for decades. The textile and food industries are equally strong, with Coca Cola, Pepsi Cola and other beverage brands, as well as fresh and canned food industries being present in the city's organized industrial zones. Traditionally, Bursa was famous for being the largest center of silk trade in the Byzantine and later the Ottoman empires, during the period of the lucrative Silk Road. Bursa was also known for its fertile soil and agricultural activities, which have decreased in the recent decades due to the heavy industrialization of the city. Bursa is also a major tourist center: one of the best skiing resorts of Turkey is located at Uludağ just next to city proper. Its thermal baths have been used for therapeutical purposes since Roman times. Apart from baths operated by hotels, Uludağ University has a physical therapy center which also makes use of thermal water. Education Uludağ University is located in Bursa and is a prominent university in Turkey's Marmara Region. It was founded in 1975, first under the name Bursa Üniversity, then re-named Uludağ Üniversity in 1982. In the 2005-06 academic year, the university had a student body of 47,000.

It was built by Ali Neccar in 1396-1399, at Sultan Bayezid I's command. The mosque is large and rectangular, with twenty domes arranged in four rows of five supported by twelve columns. Supposedly twenty domes are built instead of twenty separate mosques that Sultan Bayezid I promised for winning the Battle of Nicopolis. It has two minarets. Inside the mosque there are 192 monumental wall inscriptions written by famous calligraphers. There is also a fountain (şadırvan) inside the mosque where worshipers can perform ritual ablutions before prayer; the dome over the şadırvan is capped by a skylight, creating a soft, serene light below. The story of the şadırvan inside the mosque, which is unheard of, that the land belong to an old lady who objected to her store taken by padişah. Because consent is not given for the piece of land, prayer cannot be conducted on it thus a şadırvan is built. Architecturally şadırvan helps to have light inside the mosque that is big. The horizontally spacious and dimly lit interior is designed to feel peaceful and contemplative. The subdivisions of space formed by multiple domes and pillars create a sense of privacy and even intimacy. This atmosphere contrasts with later Ottoman mosques (see for example the work of Süleyman I's chief architect Sinan). These later mosques have increasingly elevated central domes, which create a vertical emphasis that is intended to be more overwhelming, in order to convey the power and majesty of the Ottoman Empire. It is a beautiful piece of architecture. Sister cities Bursa has twenty sister cities.

7,762 | AIM-120_AMRAAM | The AIM-120 Advanced Medium-Range Air-to-Air Missile, or AMRAAM (pronounced am-ram), is a modern Beyond Visual Range (BVR) air-to-air missile (AAM) capable of all weather day and night performance. It is also commonly known as the Slammer in USAF service. When an AMRAAM missile is being launched, NATO pilots use the brevity code Fox Three. Origins AIM-7 Sparrow MRM The AIM-7 Sparrow medium range missile (MRM) was developed by the US Navy in the 1950s as its first operational BVR air-to-air weapon. With an effective range of about , it was introduced as a radar beam riding missile and then improved to a semi-active radar guided missile which would home in on reflections from a target illuminated by the radar of the launching aircraft. It was effective at visual to beyond visual range. The early beam riding versions of the Sparrow missiles were integrated onto the F3H Demon and F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather F-4 Phantom II fighter/interceptor, which lacked an internal gun in the US Navy, USMC and early USAF versions. The F-4 mounted up to four AIM-7s carried in special recesses under the fuselage. Although designed for non-maneuvering targets such as bombers, due to poor performance against fighters over North Vietnam, these missiles were progressively improved until they proved highly effective in dogfights. Together with the short range infrared guided AIM-9 Sidewinder, they replaced the AIM-4 Falcon IR and radar guided series for use in air combat by the USAF as well. A disadvantage to semi-active homing was that only one target could be illuminated by the launch aircraft at a time; also, the launch aircraft had to remain pointed in the direction of the target (within the azimuth of the aircraft radar, up to 60 degrees off the nose on some systems), which could be difficult or dangerous in aerial combat. AIM-54 Phoenix LRM The US Navy later developed the AIM-54 Phoenix long range missile (LRM) for the fleet air defense mission. It was a large Mach 5 missile designed to counter cruise missiles and their (Bomber) launch platforms. It was intended that eight of its first incarnation would be fitted to the straight-wing F6D Missileer, and then the F-111B. Neither aircraft was introduced into service and Grumman won the competition to replace the F-111B with a dogfighter with enough weight and volume for the Phoenix that became the F-14 Tomcat. Phoenix was the first US fire-and-forget multiple launch radar-guided missile: one which used its own active guidance system to guide itself without help from the launch aircraft when it closed on its target. This gave a Tomcat with a six Phoenix load the unprecedented capability of tracking and destroying up to six targets as far as away. The Phoenix could only be carried by the F-14, making the Tomcat the only US fighter with a multiple shot, fire-and-forget radar missile targets for beyond visual range. A full load of six Phoenix missiles weighed , and with the additional of dedicated launcher, it was so heavy it exceeded a typical Vietnam-era bomb load; typically only one, two or four missiles were flown off the carrier, as a full load was too heavy to be brought back on board for landing. Although highly lauded in the press, its operational service with the US Navy was primarily as a deterrent, as its use was hampered by restrictive Rules of Engagement in such conflicts as Operations Desert Storm, Southern Watch and Iraqi Freedom. The only reported combat successes were with Iranian Tomcats against Iraqi opponents. The US Navy retired its Phoenix capability in 2005 in light of availability of the AIM-120 AMRAAM on the F/A-18 Hornet and the pending retirement of the F-14 Tomcat from active US Navy service in late 2006. ACEVAL/AIMVAL The Department of Defense conducted an extensive evaluation of air combat tactics and missile technology from 1974-78 at Nellis AFB using the F-14 Tomcat and F-15 Eagle equipped with Sparrow and Sidewinder missiles as blue force and Aggressor F-5E aircraft equipped with AIM-9L all-aspect Sidewinders as the Red force. This Joint Test and Evaluaton JT&E was designated Air Combat Evaluation/Air Intercept Missile Evaluation (ACEVAL/AIMVAL) http://www.jte.osd.mil/jtebigarticle.htm . A principal finding was the necessity to produce illumination for the Sparrow until impact resulted in the Red Force being able to launch their all-aspect Sidewinders before impact thereby resulting in mutual kills. What was needed was Phoenix type multiple launch and terminal active capability in a Sparrow size airframe. This led to a Memorandum of Agreement (MOA) with European allies (principally the UK and Germany for development) for the US develop an Advanced Medium Range Air-to-Air Missile with the USAF as lead service. The MOA also assigned responsibility for development of an Advanced Short Range Air-to-Air Missile to the European team. Requirements Surface-to-air mounting (shown: CATM-120C captive training variant) By the 1990s, the reliability of the Sparrow had improved so much from the dismal days of Vietnam that it accounted for the largest number of aerial targets destroyed in Desert Storm. But while the USAF had passed on the Phoenix and their own similar AIM-47/YF-12 to optimize dogfight performance, they still desired the Navy's multiple launch fire and forget capability for the F-15 and F-16. AMRAAM would need to be fitted on fighters as small as the F-16, and fit in the same spaces that were designed to fit the Sparrow since the Phantom. The European partners needed AMRAAM to be integrated on aircraft as small as the Sea Harrier. The US Navy needed AMRAAM to be carried on the F/A-18 Hornet and wanted capability for two to be carried on a launcher that normally carried one Sparrow to allow for more air-to-ground weapons. AMRAAM would eventually be the primary weapon for the F-22 Raptor which needed to fit all its missiles in internal weapons bays like the old F-106 Delta Darts in order to maintain a stealthy radar cross-section. The US Navy ultimately decided to retire its F-14 Tomcats and pass the Fleet Air Defense mission to the F/A-18C and F/A-18E/F Hornets, which needed even more advanced versions of AMRAAM to replace the Phoenix capability. Development AMRAAM was developed as the result of an agreement, the Family of Weapons Memorandum of Agreement no longer in effect by 1990, among the United States and several other NATO nations to develop air-to-air missiles and to share production technology. Under this agreement the U.S. was to develop the next generation medium range missile (AMRAAM) and Europe would develop the next generation short range missile (ASRAAM). When the German ASRAAM seeker development ran into problems, the MOA was abrogated and this breakdown led to the U.S. developing AIM-9X Sidewinder and Germany the IRIS-T. Although Europe initially adopted AMRAAM, an effort to develop the MBDA Meteor, a competitor to AMRAAM was begun. Eventually ASRAAM was developed solely by the UK with another source for its seeker. After protracted development, deployment of AMRAAM (AIM-120A) began in September 1991 with USAF F-15 Eagle squadrons. The US Navy followed suit in 1993 with the F/A-18C. The eastern counterpart of AMRAAM is the very similar Russian R-77 AA-12 Adder, commonly known in the west as "AMRAAMski." Likewise, France began its own missile development with the MICA concept that used the same airframe for separate radar and IR guidance versions. Operational features summary AMRAAM has an all-weather, beyond-visual-range (BVR) capability. It improves the aerial combat capabilities of U.S. and allied aircraft to meet the future threat of enemy air-to-air weapons. AMRAAM serves as a follow-on to the AIM-7 Sparrow missile series. The new missile is faster, smaller, and lighter, and has improved capabilities against low-altitude targets. It also incorporates a datalink to guide the missile to a point where its active radar turns on and makes terminal intercept of the target. An inertial reference unit and micro-computer system makes the missile less dependent upon the fire-control system of the aircraft. Once the missile closes in on the target, its active radar guides it to intercept. This feature, mistakenly called "fire and forget," frees the aircrew from the need to further provide guidance, enabling the aircrew to aim and fire several missiles simultaneously at multiple targets and perform evasive maneuvers while the missiles guide themselves to the targets. The missile also features the ability to "Home on Jamming," FAS giving it the ability to switch over from active radar homing to passive homing - homing on jamming signals from the target aircraft. Software on board the missile allows it to detect if it is being jammed, and guide on its target using the proper guidance system. This, contrary to the attack sequence on a non-jamming target, truly can be described as "fire and forget", as it does not require any guidance provided to the missile after launch. Guidance system overview Interception course stage F-14 Tomcat carrying an AMRAAM during a 1982 test. AMRAAM uses two-stage guidance when fired at long range. The aircraft passes data to the missile just before launch, giving it information about the location of the target aircraft from the launch point and its direction and speed. The missile uses this information to fly on an interception course to the target using its built in inertial navigation system (INS). This information is generally obtained using the launching aircraft's radar, although it could come from an infra-red search and tracking system (IRST), from a data link from another fighter aircraft, or from an AWACS aircraft. If the firing aircraft or surrogate continues to track the target, periodic updates are sent to the missile telling it of any changes in the target's direction and speed, allowing it to adjust its course so that it is able to close to self-homing distance while keeping the target aircraft in the basket (the radar seeker's field of view) in which it will be able to find it. Not all AMRAAM users have elected to purchase the mid-course update option, which limits AMRAAM's effectiveness in some scenarios. The RAF initially opted not to use mid-course update for its Tornado F3 force, only to discover that without it, testing proved the AMRAAM was less effective in BVR engagements than the older semi-active radar homing BAE Skyflash weapon—the AIM-120's own radar is necessarily of limited range and power compared to that of the launch aircraft. Terminal stage and impact Once the missile closes to self-homing distance, it turns on its active radar seeker and searches for the target aircraft. If the target is in or near the expected location, the missile will find it and guide itself to the target from this point. At the point where an AMRAAM switches to autonomous self-guidance, the NATO brevity code "Pitbull" would be called out on the radio, just as "Fox Three" would be called out upon launch. If the missile is fired at short range (typically visual range), it can use its active seeker just after launch, making the missile truly "fire and forget". The NATO brevity code "Maddog" is used in this situation. Kill probability and tactics General considerations Once in its terminal mode, the missile's advanced electronic counter countermeasures (ECCM) support and good maneuverability mean that the chance of it hitting or exploding close to the target is high (on the order of 90%), as long as it has enough remaining energy to maneuver with the target if it is evasive. The kill probability (Pk) is determined by several factors, including aspect (head-on interception, side-on or tail-chase), altitude, the speed of the missile and the target, and how hard the target can turn. Typically, if the missile has sufficient energy during the terminal phase, which comes from being launched close enough to the target from an aircraft flying high and fast enough, it will have an excellent chance of success. This chance drops as the missile is fired at longer ranges as it runs out of overtake speed at long ranges, and if the target can force the missile to turn it might bleed off enough speed that it can no longer chase the target. Lower-capability targets This leads to two main engagement scenarios. If the target is not armed with any medium or long-range fire-and-forget weapons, the attacking aircraft need only to get close enough to the target and launch the AMRAAM. In these scenarios, the AMRAAM has a high chance of hitting, especially against low-maneuverability targets. The launch distance depends upon whether the target is heading towards or away from the firing aircraft. In a head-on engagement, the missile can be launched at longer range, since the range will be closing fast. In this situation, even if the target turns around, it is unlikely it can speed up and fly away fast enough to avoid being overtaken and hit by the missile (as long as the missile is not released too early). It is also unlikely the enemy can outmaneuver the missile since the closure rate will be so great. In a tail-on engagement, the firing aircraft might have to close to between one-half and one-quarter maximum range (or maybe even closer for a very fast target) in order to give the missile sufficient energy to overtake the targets. If the targets are armed with missiles, the fire-and-forget nature of the AMRAAM is invaluable, enabling the launching aircraft to fire missiles at the target and subsequently take defensive actions. Even if the targets have longer-range semi-active radar homing (SARH) missiles, they will have to chase the launching aircraft in order for the missiles to track them, effectively flying right into the AMRAAM. If the target aircraft fires missiles and then turn and runs away, their own missiles will not be able to hit. Of course, if the target aircraft have long range missiles, even if they are not fire-and-forget, the fact that they force the launching aircraft to turn and run reduces the kill probability, since it is possible that without the mid-course updates the missiles will not find the target aircraft. However the chance of success is still good and compared to the relative impunity the launching aircraft enjoy, this gives the AMRAAM-equipped aircraft a decisive edge. If one or more missiles fail to hit, the AMRAAM-equipped aircraft can turn and re-engage, although they will be at a disadvantage compared to the chasing aircraft due to the speed they lose in the turn, and would have to be careful that they're not being tracked with SARH missiles. Similarly armed targets The other main engagement scenario is against other aircraft with fire-and-forget missiles like the Vympel R-77 (NATO AA-12 "Adder") — perhaps MiG-29s, Su-27s or similar. In this case engagement is very much down to teamwork and could be described as "a game of chicken." Both flights of aircraft can fire their missiles at each other beyond visual range (BVR), but then face the problem that if they continue to track the target aircraft in order to provide mid-course updates for the missile's flight, they are also flying into their opponents' missiles. Although in this regard the RVV-AE (which is the missile's export name or R-77 the official Russian Air force designation) does have an advantage as it is faster and has a greater range than the AMRAAM, meaning that the Russian airplane firing it can in fact fire first, although it still needs to lead the missile towards the target as the missiles own radar seeker has a limited range (under 10 km, as on AMRAAM). This is why teamwork is so important and advanced missiles with guidance systems with hand-off capability can help overcome this problem. This is also part of the reason why most tactics dictate holding on to missiles "until you see the whites of their eyes," or holding on to them for as long as possible. If the enemy fires missiles at maximum range, you will be able to defeat them easily without having surrendered valuable ordnance yourself. The other main tactic would be to sneak up behind the enemy aircraft and launch missiles without them noticing, giving the launching aircraft sufficient time to leave the danger zone of the enemy after launching. Even if the enemy detects the launch and turns around, the speed and possibly altitude it loses during the turn puts its missiles at an energy disadvantage which may be sufficient for the other aircraft to defeat it. This typically requires excellent ground-control intercept (GCI) or airborne radar (AWACS — Airborne Warning and Control System) facilities in order to be successful. Variants and upgrades An AIM-120 AMRAAM missile on display at the U.S. National Air and Space Museum Air-to-air missile versions There are currently three variants of AMRAAM, all in service with the United States Air Force, USN, and the United States Marine Corps. The AIM-120A is no longer in production and shares the enlarged wings and fins with the successor AIM-120B. The AIM-120C has smaller "clipped" aerosurfaces to enable internal carriage on the USAF F-22 Raptor. AIM-120B deliveries began in 1994, and AIM-120C deliveries began in 1996. The AIM-120C has been steadily upgraded since it was introduced. The AIM-120C-6 contained an improved fuse (Target Detection Device) compared to its predecessor. The AIM-120C-7 development began in 1998 and included improvements in homing and greater range (actual amount of improvement unspecified). It was successfully tested in 2003 and is currently being produced for both domestic and foreign customers. It helped the U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) can be partially offset with a longer-range AMRAAM, but note that the AMRAAM does not have a very-long range like the Phoenix missile. The AIM-120D is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (PK). Raytheon recently began testing the D model; on August 5, 2008, the company reported that an AIM-120D launched from an F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the White Sands Missile Range. Raytheon Press Release, August 5, 2008 There are also plans for Raytheon to develop a Ramjet-powered derivative of the AMRAAM, the Future Medium Range Air-Air Missile (FMRAAM). It is not known whether the FMRAAM will be produced since the target market, the British Ministry of Defence has chosen the Meteor missile over the FMRAAM for a BVR missile for the Eurofighter Typhoon aircraft. Raytheon is also working with the Missile Defense Agency to develop the Network Centric Airborne Defense Element (NCADE), an anti-ballistic missile derived from the AIM-120. This weapon will be equipped with a Ramjet engine and an IR seeker derived from the Sidewinder missile. In place of a proximity fused warhead, the NCADE will use a kinetic energy hit-to-kill vehicle based on the one used in the Navy's RIM-161 Standard Missile 3. Defense Industry Daily report, November 20, 2008 AMRAAM will continue to serve in the arsenal of the USAF, the U.S. Navy, and the U.S. Marine Corps until at least 2020 when the Joint Dual Role Air Dominance Missile (JDRADM) would potentially enter service. The -120A and -120B models are currently nearing the end of their service life while the -120D variant has just entered full production. Ground-launched systems Battery of four SL-AMRAAM on HMMWV Raytheon successfully tested launching AMRAAM missiles from a five-missile carrier on a M1097 HMMWV (hum-vee). This system will be known as the SLAMRAAM (Surface Launched (SL) and AMRAAM). They receive their initial guidance information from a radar not mounted on the vehicle. Since the missile is launched without the benefit of an aircraft's speed or high altitude, its range is considerably shorter. Raytheon is currently marketing an SL-AMRAAM EX, purported to be an extended range AMRAAM and bearing a resemblance to the ESSM (Evolved Sea Sparrow Missile). The Norwegian Advanced Surface-to-Air Missile System (NASAMS), developed by Kongsberg Defence & Aerospace, consists of a number of vehicle-pulled launch batteries (containing six AMRAAMs each) along with separate radar trucks and control station vehicles. While still under evaluation for replacement of current US Army assets, the SL-AMRAAM has been deployed in several nations military forces, including Egypt. The United Arab Emirates (UAE) has requested the purchasing of SL-AMRAAM as part of a larger 7 billion dollar foreign military sales package. The sale would include 288 AMRAAM C-7 missiles. The US Army has test fired the SL-AMRAAM from a HIMARS artillery rocket launcher as a common launcher. HIMARS Launcher Successfully Fires Air Defense Missile Operational History The AMRAAM was used for the first time on 27 December 1992, when an USAF F-16C shot down an Iraqi MiG-25 that violated the southern no-fly-zone. AMRAAM gained a second victory in January 1993 when an Iraqi MiG-23 was shot down by a USAF F-16C. The third combat use of the AMRAAM was in 1994, when a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly-zone over Bosnia. In that engagement at least 3 other Serbian aircraft were shot down by USAF F-16C fighters using AIM-9 missiles (see Banja Luka incident for more details). At that point three launches in combat resulted in three kills, resulting in the AMRAAM being informally named "slammer" in the second half of the 1990s. In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets. During the spring of 1999, AMRAAMs saw their main combat action during Operation Allied Force, the Kosovo bombing campaign. Six Serbian MiG-29 were shot down by NATO (4 USAF F-15C, 1 USAF F-16C, 1 Dutch F-16A MLU), all of them using AIM-120 missiles (the kill by the F-16C may have happened due to friendly fire, from SA-7 MANPADS fired by Serbian infantry). , the AIM-120 AMRAAM has shot down nine enemy aircraft (six MiG-29, one MiG-25, one MiG-23, and one Soko J-21 Jastreb or J-22 Orao). The AMRAAM was also involved in a friendly-fire incident when F-15 fighters patrolling the Southern No-Fly Zone inadvertently shot down a pair of U.S. Army Black Hawk helicopters. In 2005 Chile received AIM-120 AMRAAM missiles from the United States Air Force as part of the Peace Puma Plan which Chilean Air Force also received 10 F-16D fighters as part of the plan. In 2006 Poland received AIM-120C-5 missiles to arm its new F-16C/D Block 52+ fighters. In early 2006 the Pakistan Air Force (PAF) ordered 500 AIM-120C-5 AMRAAM missiles as part of a $650mn F-16 ammunition deal to equip the PAF's F-16C/D Block 52+ and F-16A/B MLU fighters. http://www.prnewswire.com/cgi-bin/micro_stories.pl?ACCT=149999&TICK=RTN&STORY=/www/story/01-15-2007/0004505958&EDATE=Jan+15,+2007 In 2007, the United States government agreed to sell 218 AIM-120C-7 missiles to Taiwan as part of a large arms sales package that also included 235 AGM-65G-2 Maverick missiles. Total value of the package, including launchers, maintenance, spare parts, support and training rounds, was estimated at around $421 million USD. This supplemented an earlier Taiwanese purchase of 120 AIM-120C-5 missiles a few years ago. 2008 has brought announcements of new or additional sales to Singapore, Finland (300 AIM-120C-7 Finland - AIM-120C-7 AMRAAM Missiles.

7,763 | Nobel_Prize | Alfred Nobel. The Nobel Prize () is a Swedish prize, established in the 1895 will of Swedish chemist and inventor Alfred Nobel; it was first awarded in Physics, Chemistry, Physiology or Medicine, Literature, and Peace in 1901. An associated prize, The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was instituted by Sweden's central bank in 1968 and first awarded in 1969. "Nobel Prize" (2007), in Encyclopædia Britannica, accessed 14 November 2007, from Encyclopædia Britannica Online: <http://www.britannica.com/eb/article-9056008>. The Nobel Prizes in the specific disciplines (Physics, Chemistry, Physiology or Medicine, and Literature) and the Prize in Economics, which is commonly identified with them, are widely regarded as the most prestigious award one can receive in those fields. The Nobel Peace Prize conveys social prestige and is often politically controversial. Ceremony With the exception of the Nobel Peace Prize, the Nobel Prizes and the Prize in Economics are presented in Stockholm, Sweden, at the annual Prize Award Ceremony on the 10th of December, the anniversary of Nobel's death. The recipients' lectures are presented in the days prior to the award ceremony. "The Nobel Prize Award Ceremonies", nobelprize.org, accessed 5 November 2007. The Nobel Peace Prize and its recipients' lectures are presented at the annual Prize Award Ceremony in Oslo, Norway, also on the 10th of December. The reason why Norway distributes a part of the prize is that at the time of Alfred Nobel's death, Norway and Sweden were joined together in a personal union known as the Swedish-Norwegian Union. "The Nobel Prize Awarders", nobelprize.org, accessed 6 November 2007. Nobel Peace Prize 2007, nobelprize.org, accessed 18 October 2007. The award ceremonies and the associated banquets are nowadays major international events. Alfred Nobel's will Alfred Nobel's will from November 25th, 1895 Five Nobel Prizes were instituted by the final will of Alfred Nobel, a Swedish chemist and industrialist, who was the inventor of the high explosive dynamite. Though Nobel wrote several wills during his lifetime, the last was written a little over a year before he died, and signed at the Swedish-Norwegian Club in Paris on 27 November 1895. Nobel bequeathed 94% of his total assets, 31 million Swedish Kronor, to establish and endow the five Nobel Prizes. "The Will of Alfred Nobel", nobelprize.org, accessed 6 November 2007. (As of 2008 that equates to 186 million US dollars.) Although Nobel's will established the prizes, his plan was incomplete and, due to various other hurdles, it took five years before the Nobel Foundation could be established and the first prizes awarded on 10 December 1901. "First Nobel Prizes: December 10, 1901", This Day in History, The History Channel, accessed 30 July 2006. Nomination and selection Compared with some other prizes, the Prize nomination and selection process is long and rigorous. This is a key reason why the Prizes have grown in importance over the years to become the most important prizes in their field. "Nobel Prizes: Selection Process", Encyclopædia Britannica Online (2007), accessed 18 October 2007. The Dalai Lama & Archbishop Desmond Tutu, Nobel Peace Prize winners. Photo by Carey Linde, 2004. The Nobel laureates are selected by their respective committees. For the Prizes in Physics, Chemistry and Economics, a committee consists of five members elected by The Royal Swedish Academy of Sciences; for the Prize in Literature, a committee of four to five members of the Swedish Academy; for the Prize in Physiology or Medicine, the committee consists of five members selected by The Nobel Assembly, which consists of 50 members elected by Karolinska Institutet; for the Peace Prize, the Norwegian Nobel Committee consists of five members elected by the Norwegian Storting (the Norwegian parliament). "The Nobel Prize in Economics", nobelprize.org, accessed 4 March 2007. In its first stage, several thousand people are asked to nominate candidates. These names are scrutinized and discussed by experts in their specific disciplines until only the winners remain. This slow and thorough process, insisted upon by Alfred Nobel, is arguably what gives the prize its importance. Despite this, there have been questionable awards and questionable omissions over the prize's century-long history. Forms, which amount to a personal and exclusive invitation, are sent to about three thousand selected individuals to invite them to submit nominations. For the peace prize, inquiries are sent to such people as governments of states, members of international courts, professors and rectors at university level, former Peace Prize laureates, current or former members of the Norwegian Nobel Committee, among others. The Norwegian Nobel Committee then bases its assessment on nominations sent in before 3 February. The submission deadline for nominations for Physics, Chemistry, Physiology or Medicine, Literature and Economics is 31 January. Self-nominations and nominations of deceased people are disqualified. The names of the nominees are never publicly announced, and neither are they told that they have been considered for the Prize. Nomination records are sealed for 50 years. In practice, some nominees do become known. It is also common for publicists to make such a claim, founded or not. After the deadline has passed, the nominations are screened by committee, and a list is produced of approximately 200 preliminary candidates. This list is forwarded to selected experts in the relevant field. They remove all but approximately 15 names. The committee submits a report with recommendations to the appropriate institution. The Assembly for the Physiology or Medicine Prize, for example, has 50 members. The institution members then select prize winners by vote. The selection process varies slightly between the different disciplines. The Literature Prize is rarely awarded to more than one person per year, whereas other Prizes now often involve collaborators of two or three. While posthumous nominations are not permitted, awards can occur if the individual died in the months between the nomination and the decision of the prize committee. The scenario has occurred twice: the 1931 Literature Prize of Erik Axel Karlfeldt, and the 1961 Peace Prize to UN Secretary General Dag Hammarskjöld. As of 1974, laureates must be alive at the time of the October announcement. There has been one laureate— William Vickrey (1996, Economics)— who died after the prize was announced but before it could be presented. Recognition time lag Nobel's will provides for prizes to be awarded in recognition for discoveries made "during the preceding year", and for the first years of the awards, the discoveries recognized were recent. However, some awards were made for discoveries that were later discredited. Taking the discrediting of a recognized discovery as an embarrassment, the awards committees began to recognize scientific discoveries that had withstood the test of time, in violation of the letter of the will. The interval between the accomplishment of the achievement being recognized and the awarding of the Nobel Prize for it varies from discipline to discipline. Prizes in Literature are typically awarded to recognize a cumulative lifetime body of work rather than a single achievement. In this case the notion of "lag" does not directly apply. Prizes in Peace, on the other hand, are often awarded within a few years of the events they recognize. For instance, Kofi Annan was awarded the 2001 Peace Prize just four years after becoming the Secretary-General of the UN. Awards in the scientific disciplines of physics and chemistry require that the significance of achievements being recognized is "tested by time." In practice it means that the lag between the discovery and the award is typically on the order of 20 years and can be much longer. For example, Subrahmanyan Chandrasekhar shared the 1983 Nobel Prize in Physics for his work on stellar structure and evolution from the 1930s. Unfortunately, not all scientists live long enough for their work to be recognized. Some important scientific discoveries are never considered for a Prize if the discoverers have died by the time the impact of their work is real. Award ceremonies Melvin Calvin receiving the Nobel Prize at the Stockholm concert hall in 1961. The committees and institutions serving as the selection boards for the Nobel Prizes typically announce the names of the laureates in October, with the Prizes awarded at formal ceremonies held annually on 10 December, the anniversary of Alfred Nobel's death. In 2005 and 2006, these Prize ceremonies were held at the Stockholm Concert Hall, with the Nobel Banquet following immediately in the Blue Hall of Stockholm City Hall. Previously, the Nobel Prizes ceremony was held in a ballroom in Stockholm's Grand Hotel. The Nobel Peace Prize ceremony has been held at the Norwegian Nobel Institute (1905–1946); at the Aula of the University of Oslo (1947–1990); and most recently at the Oslo City Hall. A maximum of three laureates and two different works may be selected per award. Each award can be given to a maximum of three recipients per year. Each "Nobel Prize Award" consists of a gold medal, a diploma, and a monetary grant: The grant is currently 10 million SEK, slightly more than US$1.2 million.

If there are two winners in a particular category, the award grant is divided equally between the recipients. If there are three, the awarding committee has the option of dividing the grant equally, or awarding one-half to one recipient and one-quarter to each of the others. It is not uncommon for recipients to donate prize money to benefit scientific, cultural or humanitarian causes. Since 1902, the King of Sweden has, with the exception of the Peace Prize, presented all the prizes in Stockholm. At first King Oscar II did not approve of awarding grand prizes to foreigners, but is said to have changed his mind once his attention had been drawn to the publicity value of the prizes for Sweden. Until the Norwegian Nobel Committee was established in 1904, the President of Norwegian Parliament made the formal presentation of the Nobel Peace Prize. The Committee's five members are entrusted with researching and adjudicating the Prize as well as awarding it. Although appointed by the Norwegian Parliament (Stortinget), they are independent and answer to no legislative authority. Members of the Norwegian government are not permitted to sit on the Committee.

The Nobel Prize medals, which have been minted by Myntverket in Sweden and the Mint of Norway since 1902, are registered trademarks of the Nobel Foundation. Their engraved designs are internationally-recognized symbols of the prestige of the Nobel Prize. All of these medal designs feature an image of Alfred Nobel in left profile on their front sides (the face of the medal). Four of the five Nobel Prize medals (Physics, Chemistry, Physiology or Medicine, and Literature) feature the same design on their faces (front sides). The reverse sides of the Nobel Prize medals for Chemistry and Physics share a design.

Due to their gold content and public display, Nobel medals are subject to medal theft. During World War II, the medals of German scientists Max von Laue and James Franck were (illegally) sent to Copenhagen for safekeeping. When Germany invaded Denmark, chemist George de Hevesy dissolved them in acid, to prevent confiscation by Nazi Germany and to prevent legal problems for the holders. After the war, the gold was recovered from solution, and the medals re-cast. Controversies and criticisms Since the first Nobel Prize was awarded in 1901, the proceedings, nominations, awards and exclusions have generated criticism and engendered much controversy. Overlooked achievements Mahatma Gandhi was nominated for the Nobel Peace Prize five times between 1937 and 1948 but never received the prize, being assassinated on 30 January 1948 two days before the closing date for the 1948 Peace Prize nominations. The Norwegian Nobel Committee had very likely planned to give him the Peace Prize in 1948 as they considered a posthumous award, but ultimately decided against it and instead chose not to award the prize that year. . The strict rules against a prize being awarded to more than three people at once is also a cause for controversy. Where a prize is awarded to recognise an achievement by a team of more than three collaborators, inevitably one or more will miss out. For example, in 2002, a Prize was awarded to Koichi Tanaka and John Fenn for the development of mass spectrometry in protein chemistry, an award that failed to recognise the achievements of Franz Hillenkamp and Michael Karas of the Institute for Physical and Theoretical Chemistry at the University of Frankfurt. Laura Spinney, "News Analysis: Nobel Prize Controversy", The Scientist 3.1 (11 December 2002): 20021211-03, accessed 28 October 2006. Another well known miss was the Nobel Prize in Physics of 1965, that was awarded to Richard P. Feynman, Julian S. Schwinger and Sin-Itiro Tomonaga but failed to recognize the contribution of Freeman C. Dyson, that demonstrated the equivalence of the formulations of quantum electrodynamics of the other three scientists. Similarly, the prohibition of posthumous awards fails to recognise achievements by a collaborator who happens to die before the prize is awarded. Rosalind Franklin, who was key in the discovery of the structure of DNA in 1953, died of ovarian cancer in 1958, four years before Francis Crick, James D. Watson and Maurice Wilkins (one of Franklin's collaborators) were awarded the Prize for Medicine or Physiology in 1962. Franklin's significant and relevant contribution was only briefly mentioned in Crick and Watson's now-famous paper: "We have also been stimulated by a knowledge of the general nature of the unpublished experimental results and ideas of Dr. M.H.F. Wilkins, Dr. R.E. Franklin, and co-workers...." J.D. Watson and F.H.C. Crick, , Nature 171.4356 (1953): 737-38. In some cases, awards have arguably omitted similar discoveries made earlier. For example, the 2000 Nobel Prize in Chemistry for "the discovery and development of conductive organic polymers" (1977) ignored the much earlier discovery of highly-conductive charge transfer complex polymers: the 1963 series of papers by Weiss, et al. reported even higher conductivity in similarly iodine-doped oxidized polypyrrole. .

Links PMID: 4359339 (PubMed - indexed for MEDLINE), accessed 28 October 2006 Lack of a Nobel Prize in Mathematics There is no Nobel Prize in Mathematics, which has led to considerable speculation about why Alfred Nobel omitted it. One story contends that this is because Nobel's partner had an affair with a mathematician, although this is neither proven to have occurred, nor to have been the reason behind the omission if such an affair did in fact take place. Lars Gårding and Lars Hörmander, "Why Is There No Nobel Prize in Mathematics?", Mathematical Intelligencer 7 (1985): 73-74. [They suggest that, primarily, Nobel did not consider Mathematics as "practical" as the other disciplines in which he established Prizes.] John E. Morrill, "Nobel Prize in Mathematics", American Mathematical Monthly 102.10 (December 1995): 888-92. JSTOR doi:10.2307/2975266. (5 pages.) (Restricted access.) [Summary of various speculations about reasons for Nobel's omitting a Prize in Mathematics, including possibly-apocryphal ones.] Some recipients of the Nobel Prize in other fields also have notable achievements in or have made outstanding contributions to mathematics; for example, Bertrand Russell was awarded the Nobel Prize in Literature (1950) and Max Born and Walther Bothe shared the Nobel Prize in Physics (1954). Some others with advanced credentials in mathematics and/or who are known primarily as mathematicians have been awarded the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel: Kenneth Arrow (1972), Leonid Kantorovich (1975), John Forbes Nash (1994), Clive W. J. Granger (2003), Robert J. Aumann (who shared the 2005 Prize with Thomas C. Schelling), and Roger Myerson and Eric Maskin (2007). Several prizes in mathematics have some similarities to the Nobel Prize. The Fields Medal is often described as the "Nobel Prize of mathematics", but it differs in being awarded only once every four years to people not older than forty years old. Other prestigious prizes in mathematics are the Crafoord Prize, awarded by the Royal Swedish Academy of Sciences since 1982; the Abel Prize which has also been called the "Nobel Prize of mathematics" and has been awarded by the Norwegian government annually, beginning in 2003; the Wolf Prize awarded once a year by the Wolf Foundation; the Shaw Prize in mathematical sciences awarded since 2004; and the Gauss Prize, granted jointly by the International Mathematical Union and the German Mathematical Society for "outstanding mathematical contributions that have found significant applications outside of mathematics," and introduced at the International Congress of Mathematicians in 2006. The Clay Mathematics Institute has devised seven "Millennium Problems," whose solution results in a significant cash award: . since it has a clear, predetermined objective for its award and since it can be awarded whenever a problem is solved, this prize also differs from the Nobel Prizes. Emphasis on discoveries over inventions Alfred Nobel left a fortune to finance annual prizes to be awarded "to those who, during the preceding year, shall have conferred the greatest benefit on mankind". One part, he stated, should be given "to the person who shall have made the most important discovery or invention within the field of physics". Nobel did not emphasize discoveries, but they have historically been held in higher respect by the Nobel prize committee than inventions: 77% of Nobel prizes in physics have been given to discoveries, compared with only 23% to inventions. Christoph Bartneck and Matthias Rauterberg in papers published in Nature and Technoetic Arts, have argued this emphasis on discoveries has moved the Nobel prize away from its original intention of rewarding the greatest contribution to society in the preceding year.

DOI: 10.1386/tear.6.1.73_1 Specially distinguished laureates Multiple laureates Since the establishment of the Nobel Prize, four people have received two Nobel Prizes: Nobel Prize Facts, nobelprize.org, accessed 18 October 2007. Maria Skłodowska-Curie: in Physics 1903, for the discovery of radioactivity; and in Chemistry 1911, for the isolation of pure radium Linus Pauling: in Chemistry 1954, for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances; and Peace 1962, for nuclear test-ban treaty activism; he is the only person to have won two unshared Nobel Prizes. See "Preface", "The Peace Prize..." and "Linus Pauling: Awards, Honors, and Medals", Linus Pauling and The Nature of the Chemical Bond: A Documentary History and Linus Pauling and the International Peace Movement, Ava Helen and Linus Pauling Papers, Special Collections, the Valley Library, Oregon State University, accessed 13 December 2007. John Bardeen: in Physics 1956, for the invention of the transistor; and Physics 1972, for the theory of superconductivity. Frederick Sanger: in Chemistry 1958, for structure of the insulin molecule; and in Chemistry 1980, for virus nucleotide sequencing. As a group, the International Committee of the Red Cross (ICRC) has received the Nobel Peace Prize three times: in 1917, 1944, and 1963. The first two prizes were specifically in recognition of the group's work during the world wars, and the third was awarded at the year of its 100-Year Anniversary. The United Nations High Commissioner for Refugees (UNHCR) has won the Peace Prize twice: in 1954 and 1981. Family laureates A number of families have included multiple laureates. The Curie family claim the most Nobel Prizes, with five: Maria Skłodowska-Curie, Physics 1903 and Chemistry 1911 Her husband Pierre Curie, Physics 1903 Their daughter Irène Joliot-Curie, Chemistry 1935 Their son-in-law Frederic Joliot-Curie, Chemistry 1935 In addition, Henry Labouisse, the husband of the Curies' second daughter Ève, was the director of UNICEF when it won the Nobel Peace Prize in 1965. Gunnar Myrdal (Economics, 1974) and wife Alva Myrdal (Peace, 1982) J. J. Thomson, awarded the Nobel prize for Physics in 1906, was the father of George Paget Thomson who was awarded the Nobel prize for Physics in 1937. William Henry Bragg shared the Nobel prize in Physics in 1915 with his son, William Lawrence Bragg. Niels Bohr won the Nobel prize in Physics in 1922, and his son Aage Bohr won the Nobel prize in Physics in 1975. Manne Siegbahn won the Nobel prize in Physics in 1924; he was the father of Kai Siegbahn who shared the Nobel prize in Physics in 1981. Hans von Euler-Chelpin shared the Nobel prize in Chemistry in 1929 with Arthur Harden. His son, Ulf von Euler, was awarded the Nobel prize in Physiology or Medicine in 1970. C.V. Raman won the Nobel prize in Physics in 1930; he was the uncle of Subrahmanyan Chandrasekhar who won the Nobel prize in Physics in 1983. Arthur Kornberg shared with Severo Ochoa the 1959 Nobel prize in Physiology or Medicine for their discovery of the mechanisms in the biological synthesis of ribonucleic acid and deoxyribonucleic acid. Physiology or Medicine prize 1959, nobelprize.org, accessed 14 January 2008 Kornberg's son Roger won the 2006 Nobel prize in Chemistry for his studies of the molecular basis of eukaryotic transcription. Chemistry prize 2006, nobelprize.org, accessed 14 January 2008 Jan Tinbergen, who was awarded the Nobel Prize for Economics in 1969, was the brother of Nikolaas Tinbergen who shared the 1973 Nobel Prize in Physiology or Medicine with Konrad Lorenz and Karl von Frisch.

7,764 | Flanders | Flanders (Dutch: ) is a geographical region located in parts of present-day Belgium, France, and the Netherlands. Over the course of history, the geographical territory that was called "Flanders" has varied. In contemporary Belgium, Flanders might be understood as the 'country of the Flemings' (as 'Ireland' is the country of the Irish). This covers the north of Belgium Flemish Region and excludes the Brussels Capital Region, the latter being shared with French speakers. For the last few decades, with the legal establishment of the Flemish Community () , the Flemings have their own political institutions. The parliament and government are the governing institutions of the Community. There is also a geographical, political and administrative entity called the Flemish Region () but the region has ceded all its competencies to the Flemish Community. Since, the institutions of the Community govern both the Community and the Region. The capital city of Flanders is Brussels. Previously, Flanders formed a county, the County of Flanders, which extended over: The Belgian provinces of West Flanders and East Flanders The French region French Flanders in the department Nord-Pas de Calais The Dutch region Zeelandic Flanders (Zeeuws-Vlaanderen) in the province of Zeeland Related to these geographical or political uses of the noun 'Flanders', and the adjective 'Flemish', they may also be used to describe several other distinct (but inter-connected) cultural, geographical, historical, linguistic or political items or entities. The term "Flanders" In Belgium The term "Flanders" has several main meanings: the social, cultural and linguistic, scientific and educational, economical and political community of the Flemings; generally called the "Flemish community" (small "c") (others refer to this as the "Flemish nation"). It has over 6 million inhabitants, or about 60%of the population of Belgium. the constituent governing institution of the federal Belgian state through the institutions named the Flemish Community (capital "C"), exercising the powers in most of those domains for the aforementioned community, and the officially Dutch-speaking Flemish Region which has powers mainly on economical matters. The Community absorbed the Region, leading to a single operative body: the Flemish government and a single legislative organ: the Flemish parliament; the geographical region in the north of Belgium coinciding with the federal Belgian state's Flemish Region but excluding the bilingual Capital Region; the geographical area comprising the two westernmost provinces of the Flemish Region, West Flanders and East Flanders, parts of a former county named Flanders. In France In the Netherlands Evolution of the term Vlaanderen literally means Flooded Land or Lowland. The name appeared first around the 8th century. The precise geographical area denominated by "Flanders" has evolved a great deal over the centuries. In the Middle Ages, the term Flanders was applied to an area in western Europe, the County of Flanders, spread over: Belgium: the area that is now approximately the Flemish provinces of East Flanders and West Flanders the French-speaking area to the west of the Scheldt river, called Tournaisis (from the town of Tournai in the province of Hainaut) France (French Flanders): in the French language: La Flandre Lilloise comprising the arrondissements of Lille and Douai, in the north of France, to which country it was ceded in the 14th century. Because French was spoken there, the area was also called la Flandre romane (Romance Flanders) or la Flandre gallicante (Gallic Flanders), or incorrectly Flandre-wallonne (Walloon Flanders) though its language was not Walloon but Picard. The city of Lille manifests itself as "Flemish", for instance by the large TGV station Lille-Flandres. the originally Dutch-speaking remainder of what is now the département Nord (Nord-Pas de Calais), called Westhoek or Maritime Flanders, ceded to France in the 17th and early 18th century, during most of which latter century the area was the province of Flanders and that of Artois. The Netherlands: a part of what is now Zeeland in south-western Netherlands, called Zeelandic Flanders (Zeeuws-Vlaanderen) The significance of the County and its counts eroded through time, but the designation remained in a very broad sense. In the Early Modern, the term Flanders was associated with the southern part of the Low Countries, the Southern Netherlands. During the 19th and 20th centuries, it became increasingly commonplace to refer to the area from De Panne to Maasmechelen, including the Belgian parts of the Duchy of Brabant and Limburg, as "Flanders". The ambiguity between this eastwardly much wider area and that of the Countship (or the Belgian parts thereof), still remains. In most present-day contexts however, the term Flanders is generally taken to refer to either the political, social, cultural and linguistic community (and the corresponding official institution, the Flemish Community), or the geographical area, one of the three institutional regions in Belgium, namely the Flemish Region. In history of art, the adjectives Flemish, Dutch and Netherlandish are commonly used to designate all the artistic production in this area. For examples, Flemish Primitives is synonym for early Netherlandish painting, Franco-Flemish School for Dutch School, and it is not uncommon to see Mosan art categorized as Flemish art. History Early history The area roughly encompassing the later geographical meanings of Flanders, had been inhabited by Celts until Germanic people began immigrating by crossing the Rhine, either gradually driving them south- or westwards, or rather merging with them. By the first century BC Germanic languages had become prevalent, and the inhabitants were called Belgæ while the area was the coastal district of Gallia Belgica, the most northeastern province of the Roman Empire at its height. The boundaries were the Marne and Seine in the West, with Brittany, and the Rhine in the East, with Frisia. This changed upon the Count of Rouen's settlement with the King of France, which made a cession of western Flanders and eastern Brittany to the Normans. Historical Flanders: County of Flanders Created in the year 862 as a feudal fief in West Francia, the County of Flanders was divided when its western districts fell under French rule in the late 12th century. The remaining parts of Flanders came under the rule of the counts of neighbouring Hainaut in 1191. The entire area passed in 1384 to the dukes of Burgundy, in 1477 to the Habsburg dynasty, and in 1556 to the kings of Spain. The western districts of Flanders came finally under French rule under successive treaties of 1659 (Artois), 1668, and 1678. During the late Middle Ages Flanders' trading towns (notably Ghent, Bruges and Ypres) made it one of the richest and most urbanised parts of Europe, weaving the wool of neighbouring lands into cloth for both domestic use and export. As a consequence, a very sophisticated culture developed, with impressive achievements in the arts and architecture, rivalling those of Northern Italy. Increasingly powerful from the 12th century, the territory's autonomous urban communes were instrumental in defeating a French attempt at annexation (1300–1302), finally defeating the French in the Battle of the Golden Spurs (July 11, 1302), near Kortrijk. Two years later, the uprising was defeated and Flanders remained part of the French Crown. Flemish prosperity waned in the following century, however, owing to widespread European population decline following the Black Death of 1348, the disruption of trade during the Anglo-French Hundred Years' War (1338–1453), and increased English cloth production. Flemish weavers had gone over to Worstead and North Walsham in Norfolk in the 12th century and established the woollen industry. Flanders in the Low Countries The Reformation Martin Luther's 95 Theses, published in 1517, had a profound effect on the Low Countries. Among the wealthy traders of Antwerp, the Lutheran beliefs of the German Hanseatic traders found appeal, perhaps partly for economic reasons in Dutch. The spread of Protestantism in this city was aided by the presence of an Augustinian cloister (founded 1514) in the St. Andries quarter. Luther, an Augustinian himself, had taught some of the monks, and his works were in print by 1518. Charles V ordered the closing of this cloister around 1525. The first Lutheran martyrs came from Antwerp. The Reformation resulted in consecutive but overlapping waves of reform: a Lutheran, followed by a militant Anabaptist, then a Mennonite, and finally a Calvinistic movement. These movements existed independently of each other. The Pragmatic Sanction of 1549, issued by Charles V, established the Low Countries as the Seventeen Provinces (or Spanish Netherlands in its broad sense) as an entity separate from the Holy Roman Empire and from France. The schism between the southern Roman Catholics and northern Calvinists resulted in the Union of Atrecht and the Union of Utrecht, respectively. Beeldenstorm Relief statues in the Cathedral of Saint Martin, Utrecht, attacked in Reformation iconoclasm in the 16th century. The birth and growth of Utrecht One hallmark of the Reformation was the belief that excessive commemoration of the saints and their images had become idolatry. Efforts to end it led to the iconoclasm of 1566 (the Beeldenstorm) – the demolition of statues and paintings depicting saints. This was associated with the ensuing religious war between Catholics and Protestants, especially the Anabaptists. The Beeldenstorm started in what is now the arrondissement of Dunkirk in French Flanders, with open-air sermons () . The first took place on the Cloostervelt near Hondschoote. The first large sermon was held near Boeschepe on July 12, 1562. These open-air sermons, mostly of Anabaptist or Mennonite signature, spread through the country. On August 10, 1566 at the end of the pilgrimage from Hondschoote to Steenvoorde, the chapel of the Sint-Laurensklooster (Monastery of Saint Lawrence) was defaced by Protestants. The iconoclasm resulted not only in the destruction of Catholic art, but also cost the lives of many priests. It next spread to Antwerp, and on August 22, to Ghent. One cathedral, eight churches, twenty-five cloisters, ten hospitals and seven chapels were attacked. From there, it further spread east and north, but in total lasted not even a month. Charles' son, King Philip II of Spain, a devout Catholic and self-proclaimed protector of the Counter-Reformation who was also the duke, count or lord of each of the Seventeen Provinces, suppressed Calvinism in Flanders, Brabant and Holland. What is now approximately Belgian Limburg was part of the Bishopric of Liège and was Catholic de facto. Part of what is now Dutch Limburg supported the Union of Atrecht, but did not sign it. The Eighty Years' War and its consequences In 1568 the Seventeen Provinces that signed the Union of Utrecht started a revolt against Philip II: the Eighty Years' War. Spanish troops quickly started fighting the rebels, but before the revolt could be completely defeated, a war between England and Spain had broken out, forcing Philip's Spanish troops to halt their advance. Meanwhile, the Spanish armies had already conquered the important trading cities of Bruges and Ghent. Antwerp, which was then arguably the most important port in the world, also had to be conquered. On August 17, 1585, Antwerp fell. This ended the Eighty Years' War for the (from now on) Southern Netherlands. The United Provinces (the Netherlands proper) fought on until 1648 – the Peace of Westphalia. While Spain was at war with England, the rebels from the north, strengthened by refugees from the south, started a campaign to reclaim areas lost to Philips II's Spanish troops. They managed to conquer a considerable part of Brabant (the later Noord-Brabant of the Netherlands), and the south bank of the Scheldt estuary (Zeeuws-Vlaanderen), before being stopped by Spanish troops. The front line at the end of this war stabilized and became the current border between present-day Belgium and the Netherlands. The Dutch (as they later became known) had managed to reclaim enough of Spanish-controlled Flanders to close off the river Scheldt, effectively cutting Antwerp off from its trade routes. First the fall of Antwerp to the Spanish and later also the closing of the Scheldt were causes of a considerable emigration of Antverpians. Footnote: An Antverpian, derived from Antverpia, the Latin name of Antwerp, is an inhabitant of this city; the term is also the adjective expressing that its substantive is from or in that city or belongs to it. Many of the Calvinist merchants of Antwerp and also of other Flemish cities left Flanders and emigrated to the north. A large number of them settled in Amsterdam, which was at the time a smaller port, only of significance in the Baltic trade. In the following years Amsterdam was rapidly transformed into one of the world's most important ports. Because of the contribution of the Flemish exiles to this transformation, the exodus is sometimes described as "creating a new Antwerp". Flanders and Brabant, due to these events, went into a period of relative decline from the time of the Thirty Years War. In the Northern Netherlands however, the mass emigration from Flanders and Brabant became an important driving force behind the Dutch Golden Age. 1581–1795: The Southern Netherlands 1609 map of the county of Flanders Although arts remained at a relatively impressive level for another century with Peter Paul Rubens (1577–1640) and Anthony van Dyck, Flanders experienced a loss of its former economic and intellectual power under Spanish, Austrian, and French rule, with heavy taxation and rigid imperial political control compounding the effects of industrial stagnation and Spanish-Dutch and Franco-Austrian conflict. 1795–1815: French Revolution and Napoleonic France In 1794 the French Republican Army started using Antwerp as the northernmost naval port of France, which country officially annexed Flanders the following year as the départements of Lys, Escaut, Deux-Nèthes, Meuse-Inférieure and Dyle. Obligatory (French) army service for all men aged 16–25 was one of the main reasons for the people's uprising against the French in 1798, known as the Boerenkrijg (Peasants' War), with the heaviest fighting in the Campine area. 1815–1830: United Kingdom of the Netherlands After the defeat of Napoleon Bonaparte at the 1815 Battle of Waterloo in Waterloo, Brabant, sovereignty over the Austrian Netherlands – Belgium minus the East Cantons and Luxembourg – was given by the Congress of Vienna (1815) to the United Netherlands (Dutch: Verenigde Nederlanden), the state that briefly existed under Sovereign Prince William I of Orange Nassau, the latter King William I of the United Kingdom of the Netherlands, after the French Empire was driven out of the Dutch territories. The United Kingdom of the Netherlands was born. The Protestant King of the Netherlands, William I rapidly started the industrialisation of the southern parts of the Kingdom. The political system that was set up however, slowly but surely failed to forge a true union between the northern and the southern parts of the Kingdom. The southern bourgeoisie mainly was Roman Catholic, in contrast to the mainly Protestant north; large parts of the southern bourgeoisie also primarily spoke French rather than Dutch. In 1815 the Dutch Senate was reinstated (Dutch: Eerste Kamer der Staaten Generaal). The nobility, mainly coming from the south, became more and more estranged from their northern colleagues. Resentment grew both among the Roman Catholics from the south and the Protestants from the north and among the powerful liberal bourgeoisie from the south and their more moderate colleagues from the north. On August 25, 1830 (after the showing of the opera 'La Muette de Portici' of Daniel Auber in Brussels) the Belgian Revolution sparked off and became a fact. On October 4, 1830, the Provisional Authority (Dutch: Voorlopig Bewind) proclaimed the independence which was later confirmed by the National Congress that issued a new Liberal Constitution and declared the new state a Constitutional Monarchy, under the House of Saxe-Coburg. Flanders now became part of the Kingdom of Belgium, which was recognized by the major European Powers on January 20, 1831. The de facto dissidence was only finally recognized by the United Kingdom of the Netherlands on April 19, 1839. Kingdom of Belgium In 1830, the Belgian Revolution led to the splitting up of the two countries. Belgium was confirmed as an independent state by the Treaty of London of 1839, but deprived of the eastern half of Limburg (now Dutch Limburg), and the Eastern half of Luxembourg (now the Grand-Duchy of Luxembourg) . Sovereignty over Zeeuws Vlaanderen, south of the Westerscheldt river delta, was left with the Kingdom of the Netherlands, which was allowed to levy a toll on all traffic to Antwerp harbour until 1863. Rise of the Flemish Movement The Belgian Revolution was not well supported in Flanders and even on the 4th of October 1830, when the Belgian independence was eventually declared, Flemish authorities refused to take orders from the new Belgian government in Brussels. Only after Flanders was subdued with the aid of a large French military force one month later, under the leadership of the Count de Pontécoulant, Flanders became a true part of Belgium. The French-speaking bourgeoisie showed very little respect for the Flemish part of the population. French became the only official language in Belgium and all secondary and higher education in the Flemish language was abolished. Belgium's co-founder, Charles Rogier, wrote in 1832 to Jean-Joseph Raikem, the minister of justice: "Les premiers principes d'une bonne administration sont basés sur l'emploi exclusif d'une langue, et il est évident que la seule langue des Belges doit être le français. Pour arriver à ce résultat, il est nécessaire que toutes les fonctions civiles et militaires soient confiées à des Wallons et à des Luxembourgeois; de cette manière, les Flamands, privés temporairement des avantages attachés à ces emplois, seront contraints d'apprendre le français, et l'on détruira ainsi peu à peu l'élément germanique en Belgique." "The first principles of a good administration are based upon the exclusive use of one language, and it is evident that the only language of the Belgians should be French. In order to achieve this result, it is necessary that all civil and military functions are entrusted to Walloons and Luxemburgers; this way, the Flemish, temporarily deprived of the advantages of these offices, will be constrained to learn French, and we will hence destroy bit by bit the Germanic element in Belgium." In 1838, another co-founder, senator Alexandre Gendebien, even declared that the Flemish were "one of the more inferior races on the Earth, just like the negroes". In 1834, all people even remotely suspected of being "Flemish minded" or calling for the reunification of the Netherlands were prosecuted and their houses looted and burnt. Flanders, until then a very prosperous European region, was not considered worthwhile for investment and scolarship. A study in 1918 demonstrated that in the first 88 years of its existence, 80% of the Belgian GNP was invested in Wallonia. This led to a wide-spread poverty in Flanders, forcing roughly 300.000 Flemish to emigrate to Wallonia to start working there in the heavy industry. All of these events led to a silent uprising in Flanders against the French-speaking domination. But it was not until 1878 that Flemish was allowed to be used for official purposes in Flanders, although French remained the only official language in Belgium. A remarkable case happened in 1872. Jozef Schoep, a Fleming, presented himself at the town hall of Sint-Jans Molenbeek to declare the birth of his son. The civil servant noted the declarations made in Flemish by Schoep in French and also addressed him in French. Schoep didn't understand the language and left the town hall as a sign of protest, without having signed the necessary documents. The Brussels' court condemned him to a fine of 50 Francs plus tax. Schoep rejected this verdict, accompanied by two sollicitors who both stated that they would plead in Flemish. The president of the court at first didn't allow this, but afterwards changed his mind. Eventually, the pleaders were allowed to use Flemish on the condition that their pleas would be translated into French by an official interpreter because the judges didn't know a single word of Flemish. Schoep's sollicitors also demanded that the State would have its plea translated, but this was again rejected by the court. Eventually the case went to the supreme court, which ruled that pleading in Flemish would be forbidden. Its verdict was based on the so-called freedom of language and that no-one could ask from any judge to know any other language but French. Mr. Schoep's son had to wait until 1882 before he'd receive a legal birth certificate. His father had died in the mean time. One year later, Flemish was again allowed in secondary schools; the first of which reopened in 1889. The Flemings had to wait until 1919 -after many Flemish soldiers died in the trenches of World War I- to have their language officially recognised and until 1930 before the first Flemish university was reopened. The first translation of the Belgian constitution in the Flemish language was not published until 1967. World War I and its consequences Flanders (and Belgium as a whole) saw some of the greatest loss of life on the Western Front of the First World War, in particular from the three battles of Ypres. Due to the hundreds of thousands of casualties at Ypres, the poppies that sprang up from the battlefield afterwards, later immortalised in the Canadian poem "In Flanders Fields", written by John McCrae, have become a symbol for lives lost in war. Flemish feeling of identity and consciousness grew through the events and experiences of war. The German occupying authorities had taken several Flemish-friendly measures. More importantly, the experiences of many Dutch-speaking soldiers on the front led by French speaking officers catalysed Flemish emancipation. The French speaking officers barked the orders in French, followed by "et pour les Flamands, la même chose", which basically meant, "Same thing for the Flemish", which obviously did not help the Flemish conscripts, who were mostly uneducated farmers and workers, who didn't speak French at all. The resulting suffering is still remembered by Flemish organizations during the yearly Yser pilgrimage in Diksmuide at the monument of the Yser Tower. Right-Wing Nationalism in the interbellum and World War II During the interbellum and World War II, several right-wing fascist and/or national-socialistic parties emerged in Belgium, of which the Flemish ones drew unto the feeling of discrimination by the Wallonians against the Flemish. Since these parties were promised more rights for the Flemings by the German government during World War II, some of them collaborated with the Nazi regime. After the war, collaborators (or people who were "Zwart", "Black" during the war) were ofcourse prosecuted and punished, and amongst those were much Flemish Nationalists, whose main goal was more rights for Flanders. As a result, up until this day Flemish Nationalism is often wrongly associated with right wing and fascist ideologies. Communautary quibbles and the Egmont pact Recent events Fake revolution On 13 December 2006, a spoof news broadcast by the Belgian Francophone public broadcasting station RTBF declared that Flanders had decided to declare independence from Belgium, and that the King and Queen of Belgium had already left the country by plane. Images were shown of people celebrating and waving flags in the background. Within minutes of the beginning of the broadcast, the news station was flooded with calls from concerned French speaking Belgians. It was only half an hour after the beginning of the broadcast that the disclaimer "This is fiction" was displayed. It was revealed that the programme had been broadcast to stimulate discussion of this subject http://en.wikinews.org/wiki/Fictional_documentary_about_Flemish_independence_causes_consternation_in_Belgium . Belgian federal elections The 2007 elections showed an extraordinary outcome in terms of support for Flemish autonomy. All the political parties that advocated a significant increase of Flemish autonomy increased their share of the votes and seats in the Belgian parliament. This was especially the case for CD&V and N-VA (forming a cartel). In addition, the very assertive Lijst Dedecker gained a spectacular entry in parliament. It got even slightly ahead of the greens (Groen!). The outright secessionist Vlaams Belang remained strong, but stalled. The main parties advocating more or less the current Belgian institutions and only modest increases in Flemish autonomy severely lost (Groen!, OpenVLD, and especially SP.A). These victories for the advocates of much more Flemish autonomy are very much in parallel with opinion polls that show a structural increase in popular support for their agenda. Several negotiators having come and gone since the last federal elections of 10 June 2007 without diminishing the disagreements between Flemish and Walloon politicians regarding a further State reform, continues to prevent the formation of the federal government. Government and politics Both the Flemish Community and the Flemish Region are constitutional institutions of the Kingdom of Belgium with precise geographical boundaries. In practice, the Flemish Community and Region together form a single body, with its own parliament and government, as the Community legally absorbed the competences of the Region. The area of the Flemish Community is represented on the maps above, including the area of the Brussels-Capital Region (hatched on the relevant map). Roughly, the Flemish Community exercises competences originally oriented towards the individuals of the Community's language: culture (including audiovisual media), education, and the use of the language. Extensions to personal matters less directly associated with language comprise sports, health policy (curative and preventive medicine), and assistance to individuals (protection of youth, social welfare, aid to families, immigrant assistance services, etc.). The area of the Flemish Region is represented on the maps above. It has a population of around 6 million (excluding the Dutch-speaking community in the Brussels Region, grey on the map for it is not a part of the Flemish Region). Roughly, the Flemish Region is responsible for territorial issues in a broad sense, including economy, employment, agriculture, water policy, housing, public works, energy, transport, the environment, town and country planning, nature conservation, credit, and foreign trade. It supervises the provinces, municipalities, and intercommunal utility companies. The number of Dutch-speaking Flemish people in the Capital Region is estimated to be between 11% and 15% (official figures do not exist as there is no language census and no official subnationality). According to a survey conducted by the Université Catholique de Louvain in Louvain-La-Neuve and published in June 2006, 51% of respondents from Brussels claimed to be bilingual, even if they do not have Dutch as their first language. Report of study by the Université Catholique de Louvain Article at Taaluniversum.org summarising report They are governed by the Brussels Region for economics affairs and by the Flemish Community for educational and cultural issues. As of 2005, Flemish institutions such as Flanders' government, parliament, etc. represent the Flemish Community and the Flemish region. The region and the community thus de facto share the same parliament and the same government. All these institutions are based in Brussels. Nevertheless, both bodies (the Community and the Region) still exist and the distinction between both is important for the people living in Brussels. Members of the Flemish parliament who were elected in the Brussels Region cannot vote on affairs belonging to the competences of the Flemish Region. The official language for all Flemish institutions is Dutch. French enjoys a limited official recognition in a dozen municipalities along the borders with French-speaking Wallonia, and a large recognition in the bilingual Brussels Region. French is widely known in Flanders, with 59% claiming to know French according to a survey conducted by the Université catholique de Louvain in Louvain-La-Neuve and published in June 2006. *http://regards.ires.ucl.ac.be/Archives/RE042.pdf Report of study by Universite Catholique de Louvain (in French)] *Article at Taaluniversum.org summarising report (in Dutch) Politics Many new political parties during the last half century were founded in Flanders: the nationalist Volksunie of which the right nationalist Vlaams Blok (Vlaams Belang) split off, and which later dissolved into the former SPIRIT (now SLP), moderate nationalism rather left of the spectrum, and the NVA, more conservative moderate nationalism; the leftist alternative/ecological Groen!; the short-lived anarchistic libertarian spark ROSSEM and more recently the conservative-right liberal Lijst Dedecker, founded by Jean-Marie Dedecker. Flemish nation For many Flemings, Flanders is more than just a geographical area or the federal institutions (Flemish Community and Region). Some even call it a nation: a people of over 6 million living in the Flemish Region and in the Brussels-Capital Region. Flemings share many political, cultural, scientific, social and educational views. Although most Flemings identify themselves more with Flanders than with Belgium, the largest group defines itself as both Flemish and Belgian. The idea of an independent Flanders finds its root in the romantic nationalism of the 19th century. Administrative divisions Provinces of Flanders The Flemish Region covers and contains over 300 municipalities. It is divided into 5 provinces: Antwerp (Antwerpen) Limburg (Limburg) East Flanders (Oost-Vlaanderen) Flemish Brabant (Vlaams-Brabant) West Flanders (West-Vlaanderen) Independently from the provinces, Flanders has its own local institutions in the Brussels-Capital Region, being the Vlaamse GemeenschapsCommissie (VGC), and its municipal antennae (Gemeenschapscentra, community centers for the Flemish community in Brussels). These institutions are independent from the educational, cultural and social institutions which depend directly on the Flemish government. They exert, among others, all those cultural competences that outside Brussels fall under the provinces. Geography and climate Antwerp, Ghent, Bruges and Leuven are the largest cities of the Flemish Region. Antwerp has a population of more than 470,000 citizens and is the largest city, Ghent has a population of 240,000 citizens, followed by Bruges with 100,000 citizens and Leuven counts almost 100,000 citizens. Brussels is a part of Flanders as far as community matters are concerned, but does not belong to the Flemish Region. Flanders has two main geographical regions: the coastal Yser basin plain in the north-west and a central plain. The first consists mainly of sand dunes and clayey alluvial soils in the polders. Polders are areas of land, close to or below sea level that have been reclaimed from the sea, from which they are protected by dikes or, a little further inland, by fields that have been drained with canals. With similar soils along the lowermost Scheldt basin starts the central plain, a smooth, slowly rising fertile area irrigated by many waterways that reaches an average height of about five metres (16.4 ft) above sea level with wide valleys of its rivers upstream as well as the Campine region to the east having sandy soils at altitudes around thirty metres The altitude of Mechelen, approximately in the middle of the central plain forming the large part of Flanders, is 7 m (23 ft) above sea level. Already closer to the higher southern Wallonia, the more eastern Leuven and Hasselt reach altitudes up to about 40 m (131 ft) Near its southern edges close to Wallonia one can find slightly rougher land richer of calcium with low hills reaching up to 150 m (492 ft) and small valleys, and at the eastern border with the Netherlands, in the Meuse basin, there are marl caves (mergelgrotten). Its exclave around Voeren between the Dutch border and the Walloon province of Liège attains a maximum altitude of 288 m (945 ft) above sea level. The climate is maritime temperate, with significant precipitation in all seasons (Köppen climate classification: Cfb; the average temperature is 3 °C (37 °F) in January, and 18 °C (64 °F) in July; the average precipitation is 65 millimetres (2.6 in) in January, and 78 millimetres (3.1 in) in July). Economy Total GDP of the Flemish Region in 2004 was € 165,847 million (Eurostat figures). Per capita GDP at purchasing power parity was 23% above the EU average. Flanders was one of the first continental European areas to undergo the Industrial Revolution, in the 19th century. Initially, the modernization relied heavily on food processing and textile. However, by the 1840s the textile industry of Flanders was in severe crisis and there was famine in Flanders (1846–50). After World War II, Antwerp and Ghent experienced a fast expansion of the chemical and petroleum industries. Flanders also attracted a large majority of foreign investments in Belgium, among others thanks to its well-educated and industrious labour force. The 1973 and 1979 oil crises sent the economy into a recession. The steel industry remained in relatively good shape. In the 1980s and 90s, the economic centre of the Belgium continued to shift further to Flanders. Nowadays, the Flemish economy is mainly service-oriented, although its diverse industry remains a crucial force. Flemish productivity per capita is between 20 and 25% higher than that in Wallonia. Flanders has developed an excellent transportation infrastructure of ports, canals, railways and highways. Antwerp is the second-largest European port, after Rotterdam. In 1999, the euro, the single European currency, was introduced in Flanders. It replaced the Belgian franc in 2002. The Flemish economy is strongly export oriented, in particular of high value-added goods. The main imports are food products, machinery, rough diamonds, petroleum and petroleum products, chemicals, clothing and accessories, and textiles. The main exports are automobiles, food and food products, iron and steel, finished diamonds, textiles, plastics, petroleum products, and nonferrous metals. Since 1922, Belgium and Luxembourg have been a single trade market within a customs and currency union—the Belgium-Luxembourg Economic Union. Its main trading partners are Germany, the Netherlands, France, the United Kingdom, Italy, the United States and Spain. Demographics The highest population density is found in the area circumscribed by the Brussels-Antwerp-Ghent-Leuven agglomerations that surround Mechelen and is known as the Flemish Diamond, in other important urban centres as Bruges and Kortrijk to the west, and notable centres Turnhout and Hasselt to the east. As of April 2005, the Flemish Region has a population of 6,058,368 and about 15% of the 1,018,029 people in the Brussels Region are also considered Flemish. Official statistics of Belgium The (Belgian) laicist constitution provides for freedom of religion, and the various government generally respects this right in practice. Since independence, Catholicism, counterbalanced by strong freethought movements, has had an important role in Belgium's politics, since the 20th century in Flanders mainly via the Christian trade union (ACV) and the Christian Democrat party (CD&V). According to the 2001 Survey and Study of Religion, about 47 percent of the Belgian population identify themselves as belonging to the Catholic Church while Islam is the second-largest religion at 3.5 percent. A 2006 inquiry in Flanders, considered more religious than Wallonia, showed 55% to call themselves religious, 36% believe that God created the world. Inquiry by 'Vepec', 'Vereniging voor Promotie en Communicatie' (Organisation for Promotion and Communication), published in Knack magazine 22 November 2006 p. 14 [The Dutch language term 'gelovig' is in the text translated as 'religious', more precisely it is a very common word for believing in particular in any kind of God in a monotheistic sense, and/or in some afterlife. (See also Religion in Belgium). Education is compulsory from the ages of six to 18, but most Flemings continue to study until around 23. Among the OECD countries in 1999, Flanders had the third-highest proportion of 18–21-year-olds enrolled in postsecondary education. Flanders also scores very high in international comparative studies on education. Its secondary school students consistently rank among the top three for mathematics and science. However, the success is not evenly spread: ethnic minority youth score consistently lower, and the difference is larger than in most comparable countries. Mirroring the historical political conflicts between the freethought and Catholic segments of the population, the Flemish educational system is split into a laïque branch controlled by the communities, the provinces, or the municipalities, and a subsidised religious—mostly Catholic—branch controlled by both the communities and the religious authorities—usually the dioceses. It should however be noted that—at least for the Catholic schools—the religious authorities have very limited power over these schools. Smaller school systems follow 'methodical pedagogies' (Steiner, Montessori, Freinet, ...) or serve the Jewish and Protestant minorities. Language and culture The standard language in Flanders is Dutch; a single authority, the Nederlandse Taalunie, comprising appointees of the Belgian and Netherlands governments, sets standards for spelling and grammar. The term Flemish can be applied to the Dutch spoken in Flanders; it shows many regional and local variants. At first sight, Flemish culture is defined by its language and its gourmandic mentality, as compared to the more Calvinistic Dutch culture. Some claim Flemish literature does not exist, because it is 'readable' by both Dutch and Flemings. This is correct for the vast majority of the literature written by Flemings, although one might argue a distinct Flemish literature already began in the 19th century, when most of the European Nation-states arose, with writers and poets such as Guido Gezelle, who not only explicitly referred to his writings as Flemish, but actually used it in many of his poems, and strongly defended it: Original "Gij zegt dat ‘t vlaamsch te niet zal gaan: ‘t en zal! dat ‘t waalsch gezwets zal boven slaan: ‘t en zal! Dat hopen, dat begeren wij: dat zeggen en dat zweren wij: zoo lange als wij ons weren, wij: ‘t en zal, ‘t en zal, ‘t en zal!" Translation "You say Flemish will disappear: It will not! that Walloonish rantings will prevail: It will not! This we hope, this we crave: this we say and this we swear: as long as we defend ourselves, we: It will not, It will not, It will not!" This distinction in literature is also made by some experts such as Kris Humbeeck, professor of Literature at the University of Antwerp . Nevertheless, the near totality of Dutch-language literature read (and appreciated to varying degrees) in Flanders is the same as in the Netherlands. Influential Flemish writers include Ernest Claes, Stijn Streuvels and Felix Timmermans; their novels mostly describe rural life in Flanders in the 19th and beginning of the 20th century. They were widely read by the elder generation but are considered somewhat old-fashioned by present day critics. Some famous Flemish writers from the early 20th century wrote in French, like Nobel Prize winners (1911) Maurice Maeterlinck and Emile Verhaeren. Still widely read and translated into other languages (including English) are the novels of authors like Willem Elsschot, Louis Paul Boon and Hugo Claus. The younger generation is represented by novelists like Tom Lanoye, Herman Brusselmans and the poet Herman de Coninck. Flanders is also famous for its Flemish art. "Fleming" as a surname The surname "Fleming" or "Flemming" is common in England, Scotland, Ireland, and other English-speaking countries, and also occurs in Scandinavian countries such as Denmark, Sweden, and Finland. The wide distribution of the name indicates a long-standing Flemish diaspora.

7,765 | Fart | Fart is an English language vulgarism most commonly used in reference to flatulence. The word "fart" is generally considered unsuitable in a formal environment by modern English speakers, and it may be considered vulgar or offensive in some situations. Fart can be used as a noun or a verb. Dictionary.com The immediate roots are in the Middle English words ferten, feortan or farten; which is akin to the Old High German word ferzan. Cognates are found in old Norse, Slavic and also Greek and Sanskrit. The word "fart" has been incorporated into the colloquial and technical speech of a number of occupations, including computing. Fart is sometimes used as a nonspecific derogatory epithet, often to refer to 'an irritating or foolish person', and potentially an elderly person, described as an 'old fart'. This may be taken as an insult when used in the second or third person, but can potentially be a term of endearment, or an example of self deprecatory humour when used in the first person. Hacker dictionary The phrase 'boring old fart' was popularised in the UK in the late 1970s by the New Musical Express while chronicling the rise of punk. It was used to describe hippies and establishment figures in the music industry, forces of inertia against the new music. Etymology The English word fart is one of the oldest words in the English vocabulary. Its Indo-European origins are confirmed by the many cognate words in other Indo-European languages: It is cognate with Greek πέρδομαι (perdomai), Latin pēdĕre, Sanskrit pardate, Avestan pərəδaiti, and Russian пердеть (perdet'), Polish "pierd" << PIE *perd [break wind loudly] or *pezd [the same, softly] (with a Polish false friend "fart" meaning "fluke, good luck") all of which mean the same thing. Like most Indo-European roots in the Germanic languages, it was altered by Grimm's law, so that Indo-European /p/ > /f/, and /d/ > /t/, as the German cognate furzen also manifests. The American Heritage Dictionary of the English Language (4th edition, 2000) Dictionnaire Hachette de la Langue Française, (Hachette, 1995) ISBN 0-317-45629-6 T. G. Tucker, Etymological Dictionary of Latin, (Halle, 1931, repr. Ares Publishers, 1985) ISBN 0-89005-172-0 Vulgarity and offensiveness In certain circles the word is considered merely a common profanity with an often humorous connotation. For example, a person may be referred to as a 'fart', or an 'old fart', not necessarily depending on the person's age. This may convey the sense that a person is overly boring or fussy and be intended as an insult, mainly when used in the second or third person. For example '"he's a boring old fart!" However the word may be used as a colloquial term of endearment or a in an attempt at humorous self-deprecation (e.g., in such phrases as "I know I'm just an old fart" or "you do like to fart about!"). 'Fart' is often only used as a term of endearment when the subject is personally well known to the user. In both cases though, it tends to refer to personal habits or traits that the user considers to be a negative feature of the subject, even when it is a self-reference. For example, when concerned that a person is being overly methodical they might say 'I know I'm being an old fart', potentially to forestall negative thoughts and opinions in other. When used in an attempt to be offensive, the word is still considered vulgar, but it remains a mild example of such an insult. This usage dates back to the Medieval period, where the phrase 'not worth a fart' would be applied to a item held to be worthless. Historical examples The word fart in Middle English occurs in "Sumer Is Icumen In", where one sign of summer is "bucke uerteþ" (the buck farts). It appears in several of Geoffrey Chaucer's Canterbury Tales. In "The Miller's Tale", Absolon has already been tricked into kissing Alison's buttocks when he is expecting to kiss her face. Her boyfriend Nicholas hangs his buttocks out of a window, hoping to trick Absolon into kissing his buttocks in turn and then passes gas in the face of his rival. In "The Summoner's Tale", the friars in the story are to receive the smell of a fart through a twelve spoked wheel. The word fart was in pre-modern times not considered especially vulgar and could often be encountered in literary works. Samuel Johnson's A Dictionary of the English Language, published in 1755, included the word. Johnson defined it with two poems, one by Jonathan Swift, the other by Sir John Suckling. An ill wind. Some fascinating facts about farting In 1607, a group of Members of Parliament had written a ribald poem entitled The Parliament Fart, as a symbolic protest against the conservatism of the House of Lords and the king, James I. Ode to fart gets airing at last Modern usage By the early twentieth century, the word "fart" had come to be considered rather vulgar in most English-speaking cultures. While not one of George Carlin's original seven dirty words, he noted in a later routine that the word fart , ought to be added to "the list" of words that were not acceptable (for broadcast) in any context (which have non-offensive meanings). George Carlin Thomas Wolfe had the phrase 'a fizzing and sulphuric fart' cut out of his 1929 work Look Homeward, Angel by his publisher. Ernest Hemingway, who had the same publisher, accepted the principle that fart could be cut, on the grounds that no one should use words only to shock. The hippy movement in the 1970s saw a new definition develop, with the use of fart as a personal noun, to describe a 'detestable person, or someone of small stature or limited mental capacity', gaining wider and more open usage as a result. Rhyming slang developed the alternative form 'Raspberry Tart', later shortened to 'Raspberry', and occasionally 'Razz'. This was associated with the phrase 'blowing a raspberry'. The word has become more prevalent, and now features in children's literature, such as the Walter the Farting Dog series of children's books, Robert Munsch's Good Families Don't and The Gas We Pass by Shinta Cho. Teachers in American schools have been encouraged to use books about farts to make children more comfortable with the word. In other usage As a verb phrase Following on from 'fart' being used to refer to an irritating or foolish person, the verb phrase 'fart around', meaning to spend time foolishly or aimlessly is also utilised. Again this can be in a humorous attempt at a term of endearment, or as an insult. The implication is that the person is being a 'fart', and otherwise is wasting time, or achieving little. As a lapse in concentration The term 'brain fart', often used as a synonym for a 'senior moment', or a momentary lapse in concentration or occurrence of forgetfulness, such as an Absence seizure. It is a more modern usage, similar in derivation to the term fart to denote uselessness or a period of low achievement. In some cases, particularly the corporate world, it may be used to describe a situation where a person has spoken out of turn to a superior figure. This usage implies a momentary lack of forethought and a break in good sense, which may be colloquially explained away as the result of a 'brain fart'. net lingo Rules of farting According to the The Alphabet of Manliness, the assigning of blame for farting is part of a ritual of behaviour. This involves deception and a back and forth rhyming game including phrases such as: He who observed it served it. He who first detected it ejected it. He who said the rhyme did the crime. Whoever blamed it flamed it. Whoever spoke last set off the blast. Whoever rhymed it grimed it. Whoever denied it supplied it. He who smelt it dealt it. The next person who speaks is the person who reeks. Other usages Fart has been used to name cocktails, an example being a 'Duck fart', playing on the humorous reference to flatulence—an example of toilet humour. Drinksmixer.con It has also been used in the term 'fart sack', military slang for a bed or sleeping bag. Fart sack at Sex-lexis A 'nun's fart' is a French term for a type of sweet dessert sprinkled with sugar.

7,766 | Hawker_Siddeley_Harrier | The Hawker Siddeley Harrier GR.1/GR.3 and the AV-8A Harrier are the first generation of the Harrier series, the first operational close-support and reconnaissance fighter aircraft with Vertical/Short Takeoff and Landing (V/STOL) capabilities, colloquially referred to as a "jump jet". The Harrier was the only truly successful V/STOL design of the many that arose from the 1960s. In the 1970s, the Harrier was developed into the radar-equipped BAE Sea Harrier for the Royal Navy. The Harrier was also extensively redesigned as the BAE Harrier II and AV-8B Harrier II, which were built by British Aerospace and McDonnell Douglas. Development Background The Harrier's lineage began with the Hawker Siddeley P.1127. Design began in 1957 by Sir Sydney Camm, Ralph Hooper of Hawker Aviation and Stanley Hooker (later Sir Stanley) of the Bristol Engine Company. Rather than using rotors or a direct jet thrust the P.1127 had an innovative vectored thrust turbofan engine and the first vertical takeoff was on 21 October 1960. Six prototypes were built in total, one of which was lost at an air display. The immediate development of the P.1127 was the Hawker Siddeley Kestrel FGA.1, which appeared after Hawker Siddeley Aviation was created. The Kestrel's first flight was on 7 March 1964. It was strictly an evaluation aircraft, and only nine were built. These equipped the Tripartite Evaluation Squadron formed at RAF West Raynham in Norfolk, numbering 10 pilots from the RAF, USA and West Germany. One aircraft was lost and six of the remainder were transferred to the U.S. for evaluation by the Army, Air Force and Navy, designated XV-6A Kestrel. Evans, A. "American Harrier - Part One", Model Aircraft Monthly Vol.8, Issue 4, pp. 36–39. At the time of the development of the P.1127, Hawker had started on a design for a supersonic version, the Hawker P.1154. After this was cancelled in 1965, the RAF began looking at a simple upgrade of the Kestrel as the P.1127 (RAF). An order for 60 production aircraft was received from the RAF in mid-1966, and the first pre-production Harriers, then known as the P.1127 (RAF) were flying by mid-1967, becoming known as Harrier GR.1. Production The Hawker Siddeley Harrier GR.1 was the first production model derived from the Kestrel, it first flew on 28 December 1967, and entered service with the RAF on 1 April 1969. Construction took place at factories in Kingston upon Thames in southwest London and at Dunsfold, Surrey. The latter adjoined an airfield used for flight testing; both factories have since closed. The ski-jump technique for STOVL used by Harriers launched from Royal Navy aircraft carriers was tested at the Royal Navy's airfield at RNAS Yeovilton (HMS Heron), Somerset. Their flight decks were designed with an upward curve to the bow following the successful conclusion of those tests. The Harrier GR.3 featured improved sensors (such as a laser tracker in the lengthened nose), countermeasures and a further upgraded Pegasus Mk 103 and was to be the ultimate development of the 1st generation Harrier. The AV-8As of the United States Marine Corps were very similar to the early GR.1 version, but with the more-powerful engine of the GR.3. The aircraft was powered by a 21,500 lbf (95.6 kN) thrust Roll-Royce Pegasus Mk 103 (F402-RR-402) turbofan engine. The AV-8A was armed with two 30 mm ADEN cannons (podded under the fuselage) and two AIM-9 Sidewinder air-to-air missiles. A total of 113 were ordered for the US Marines and the Spanish Navy. Design Controls and handling The Harrier was a manoeuvrable attack aircraft. The air combat technique of vectoring in forward flight, or "viffing", was formally developed by the USMC in the Harrier to outmanoeuvre a hostile aircraft or other inbound weapons. Norden 2006, pp. 33–34. Spick and Gunston 2000, pp. 382–383. In addition to normal flight controls, the Harrier has a lever for controlling the direction of the four vectorable nozzles. The nozzles point rearward with the lever in the forward position for horizontal flight. With the lever back, the nozzles point downward for vertical takeoff or landing.

Jenkins 1998, p. 25. Operational history The first major combat experience for the Harrier in British service was during the Falklands War where both the BAE Sea Harrier FRS.1 and Harrier GR.3 were used. The Sea Harrier, developed from the GR.3, was important to the naval activities. Twenty Sea Harriers were operated from the carriers HMS Hermes and Invincible mainly for fleet air defence. Although they destroyed 21 Argentine aircraft in air combat (in part due to using the American-supplied latest variant of the Sidewinder missile and the Argentine aircraft operating at extreme range) they couldn't establish complete air superiority and prevent Argentine attacks during day or night nor stop the daily flights of C-130 Hercules transports to the islands. Harrier GR.3s were operated by the RAF from Hermes, and provided close support to the ground forces and attacked Argentine positions. However, they were unable to destroy the Stanley runway. If most of the Sea Harriers had been lost, the GR.3s would have replaced them in air patrol duties. Four Harriers GR.3s were lost to ground fire, accidents, or mechanical failure. Harriers lost in the Falklands The RAF Harriers would not see further combat, as the Hawker Siddeley airframes were replaced by the larger Harrier II developed jointly by McDonnell Douglas and British Aerospace.

Fifty-eight GR.1As entered RAF service, 17 GR.1As were produced, a further 41 GR.1s upgraded. Harrier GR.3 Featured improved sensors (such as a laser tracker in the lengthened nose and radar warning receiver on the fin and tail boom) and a further uprated Pegasus Mk 103.

7,767 | Cooking | Cooking with a Wok in China A cook sautees onions and green peppers on a skillet Cooking is the process of preparing food by applying heat, selecting, measuring and combining of ingredients in an ordered procedure for producing safe and edible food. The process encompasses a vast range of methods, tools and combinations of ingredients to alter the flavor, appearance, texture, or digestibility of food. Factors affecting the final outcome include the variability of ingredients, ambient conditions, tools, and the skill of the individual doing the actual cooking. The diversity of cooking worldwide is a reflection of the aesthetic, agricultural, economic, cultural, social and religious diversity throughout the nations, races, creeds and tribes across the globe. Applying heat to a food usually, though not always, chemically transforms it, thus changing its flavor, texture, consistency, appearance, and nutritional properties. Methods of cooking that involve the boiling of liquid in a receptacle have been practised at least since the 10th millennium BC, with the introduction of pottery. Proteins Edible animal material, including muscle, offal, milk and egg white, contains substantial amounts of protein. Almost all vegetable matter (in particular legumes and seeds) also includes proteins, although generally in smaller amounts. These may also be a source of essential amino acids. When proteins are heated they become de-natured and change texture. In many cases, this causes the structure of the material to become softer or more friable - meat becomes cooked. In some cases, proteins can form more rigid structures, such as the coagulation of albumen in egg whites. The formation of a relatively rigid but flexible matrix from egg white provides an important component of much cake cookery, and also underpins many desserts based on meringue. Liquids Cooking often involves water which is frequently present as other liquids, both added in order to immerse the substances being cooked (typically water, stock or wine), and released from the foods themselves. Liquids are so important to cooking that the name of the cooking method used may be based on how the liquid is combined with the food, as in steaming, simmering, boiling, braising and blanching. Heating liquid in an open container results in rapidly increased evaporation, which concentrates the remaining flavor and ingredients - this is a critical component of both stewing and sauce making. Fat Fats and oils come from both animal and plant sources. In cooking, fats provide tastes and textures. When used as the principal cooking medium (rather than water), they also allow the cook access to a wide range of cooking temperatures. Common oil-cooking techniques include sauteing, stir-frying, and deep-frying. Commonly used fats and oils include butter; olive oil; vegetable oils such as sunflower oil, corn oil, and safflower oil; animal fats such as lard, schmaltz, and beef fat (both dripping and tallow); and seed oils such as rapeseed oil (Canola or mustard oil), sesame oil, soybean oil, and peanut oil. The inclusion of fats tends to add flavour to cooked food, even though the taste of the oil on its own is often unpleasant. This fact has encouraged the popularity of high fat foods, many of which are classified as junk food. Carbohydrates Carbohydrates include simple sugars such as glucose (from table sugar) and fructose (from fruit), and starches from sources such as cereal flour, rice, arrowroot, potato. The interaction of heat and carbohydrate is complex. Long-chain sugars such as starch tend to break down into simpler sugars when cooked, while simple sugars can form syrups. If sugars are heated so that all water of crystallisation is driven off, then caramelization starts, with the sugar undergoing thermal decomposition with the formation of carbon, and other breakdown products producing caramel. Similarly, the heating of sugars and proteins elicits the Maillard reaction, a basic flavor-enhancing technique. An emulsion of starch with fat or water can, when gently heated, provide thickening to the dish being cooked. In European cooking, a mixture of butter and flour called a roux is used to thicken liquids to make stews or sauces. In Asian cooking, a similar effect is obtained from a mixture of rice or corn starch and water. These techniques rely on the properties of starches to create simpler mucilaginous saccharides during cooking, which causes the familiar thickening of sauces. This thickening will break down, however, under additional heat. Vitamins and minerals Vitamins are materials required for normal human metabolism but which the body cannot manufacture itself and which must therefore come from food. Vitamins come from a number of sources including fresh fruit and vegetables (Vitamin C), carrots, liver (Vitamin A), cereal bran, bread, liver e ( B vitamins), fish liver oil (Vitamin D) and fresh green vegetables (Vitamin K). Many minerals are also essential in small quantities including iron, calcium, magnesium and sulphur; and in very small quantities copper, zinc and selenium. Micronutrients from fruit and vegetables may be destroyed or eluted by cooking. However, research led by Dr Sue Southon of the Institute of Food Research in Norwich has found that cooking vegetables facilitates the absorption of micronutrients. Cooked food may therefore provide more health benefits than raw food. http://news.bbc.co.uk/1/hi/health/359175.stm Vitamins from fresh vegetables and fruit may be destroyed or eluted by cooking and the greatest benefit is derived from uncooked material. Vitamin C is especially prone to oxidation during cooking and may be completely destroyed by protracted coking. Minerals may also be eluted by extended boiling. Cooking methods For various cooking methods, see :Category:Cooking techniques. Food safety Using a chopping board. When heat is used in the preparation of food, it can kill or inactivate potentially harmful organisms including bacteria and viruses. The effect will depend on temperature, cooking time, and technique used. The temperature range from 41°F to 135°F (5°C to 57°C) is the "food danger zone." Between these temperatures bacteria can grow rapidly. Under optimal conditions, E. coli, for example, can double in number every twenty minutes. The food may not appear any different or spoiled but can be harmful to anyone who eats it. Meat, poultry, dairy products, and other prepared food must be kept outside of the "food danger zone" to remain safe to eat. Refrigeration and freezing do not kill bacteria, but only slow their growth. When cooling hot food, it should not be left standing or in a blast chiller for more than 90 minutes. Cutting boards are a potential breeding ground for bacteria, and can be quite hazardous unless safety precautions are taken. Plastic cutting boards are less porous than wood and have conventionally been assumed to be far less likely to harbor bacteria. This has been debated, and some research has shown wooden boards are far better. Washing and sanitizing cutting boards is highly recommended, especially after use with raw meat, poultry, or seafood. Hot water and soap followed by a rinse with an antibacterial cleaner (dilute bleach is common in a mixture of 1 tablespoon per gallon of water, as at that dilution it is considered food safe, though some professionals choose not to use this method because they believe it could taint some foods), or a trip through a dishwasher with a "sanitize" cycle, are effective methods for reducing the risk of illness due to contaminated cooking implements. Effects on nutritional content of food Cooking prevents many foodborne illnesses that would otherwise occur if the raw food was eaten. Cooking also increases the digestibility of some foods such as grains. Many foods are inedible raw. For example kidney beans are toxic when raw, due to the chemical phytohaemagglutinin. . Proponents of Raw foodism argue that cooking food increases the risk of some of detrimental effects on food or health. They point out that the cooking of vegetables and fruit containing vitamin c both elutes the vitamin into the cooking water and degrades the vitamin through oxidation. Peeling vegetables can also substantially reduce the vitamin C content , especially in the case of potatoes where most vitamin C is in the skin. However, research has also suggested that a greater proportion of nutrients present in food is absorbed from cooked foods than from uncooked foods. http://news.bbc.co.uk/1/hi/health/359175.stm Baking, grilling or broiling food , especially starchy foods, until a toasted crust is formed generates significant concentrations of acrylamide, a possible carcinogen. Cooking dairy products may reduce a protective effect against colon cancer. Researchers at the University of Toronto suggest that ingesting uncooked or unpasteurized dairy products (see also Raw milk) may reduce the risk of colon cancer. Mice and rats fed uncooked sucrose, casein, and beef tallow had one-third to one-fifth the incidence of microadenomas as the mice and rats fed the same ingredients cooked. Promotion of colonic microadenoma growth in mice and rats fed cooked sugar or cooked casein and fat Promotion of Aberrant Crypt Foci and Cancer in Rat Colon by Thermolyzed Protein This claim, however, is contentious. According to the Food and Drug Administration of the United States, health benefits claimed by raw milk advocates do not exist. "Got Milk?" by Linda Bren. FDA Consumer. Sept-Oct 2004. "The small quantities of antibodies in milk are not absorbed in the human intestinal tract," says Barbara Ingham, Ph.D., associate professor and extension food scientist at the University of Wisconsin-Madison. "There is no scientific evidence that raw milk contains an anti-arthritis factor or that it enhances resistance to other diseases." Several studies published since 1990 indicate that cooking muscle meat creates heterocyclic amines (HCAs), which are thought to increase cancer risk in humans. Researchers at the National Cancer Institute found that human subjects who ate beef rare or medium-rare had less than one third the risk of stomach cancer than those who ate beef medium-well or well-done. http://www.cancer.gov/cancertopics/factsheet/Risk/heterocyclic-amines National Cancer Institute - Heterocyclic Amines in Cooked Meats While eating muscle meat raw may be the only way to avoid HCAs fully, the National Cancer Institute states that cooking meat below creates "negligible amounts" of HCAs. Also, microwaving meat before cooking may reduce HCAs by 90%. http://www.cancer.gov/cancertopics/factsheet/Risk/heterocyclic-amines Nitrosamines, present in processed and cooked foods, have also been noted as being carcinogenic, being linked to colon cancer. Research has shown that grilling or barbecuing meat and fish increases levels of carcinogenic Polycyclic aromatic hydrocarbons (PAH). However, meat and fish only contribute a small proportion of dietary PAH intake - most intake comes from cereals, oils and fats. http://ec.europa.eu/food/fs/sc/scf/out154_en.pdf German research in 2003 showed significant benefits in reducing breast cancer risk when large amounts of raw vegetable matter are included in the diet. The authors attribute some of this effect to heat-labile phytonutrients. Nutr Cancer. 2003;46(2):131-7 Heating sugars with proteins or fats can produce Advanced glycation end products ("glycotoxins"). These have been linked to ageing and health conditions such as diabetes. Science of cooking The application of scientific knowledge to cooking and gastronomy has become known as molecular gastronomy. This is a subdiscipline of food science. Important contributions have been made by scientists, chefs and authors such as Herve This (chemist), Nicholas Kurti (physicist), Peter Barham (physicist), Harold McGee (author), Shirley Corriher (biochemist, author), Heston Blumenthal (chef), Ferran Adria (chef), Robert Wolke (chemist, author) and Pierre Gagnaire (chef). Chemical processes central to cooking include the Maillard reaction - a form of non-enzymatic browning involving an amino acid, a reducing sugar, and heat. History of cooking There is, as yet, no clear evidence as to when cooking was invented. Richard Wrangham argues that cooking was invented as far back as 1.8 million to 2.3 million years ago. Other researchers believe that cooking was invented as late as 40,000 or 10,000 years ago. Evidence of fire is inconclusive as wildfires started by lightning-strikes are still common in East Africa and other wild areas, and it is difficult to determine as to when fire was used for cooking, as opposed to just being used for warmth or for keeping predators away. Most anthropologists contend that cooking fires began in earnest barely 250,000 years ago, when ancient hearths, earth ovens, burnt animal bones, and flint appear across Europe and the middle East. Back 2 million years ago, the only sign of fire is burnt earth with human remains, which most anthropologists consider coincidence rather than evidence of intentional fire.

7,768 | Lisp_machine | A Knight machine preserved in MIT's museum. Lisp machines were general-purpose computers designed (usually through hardware support) to efficiently run Lisp as their main software language. In a sense, they were the first commercial single-user workstations. Despite being modest in number (perhaps 7,000 units total as of 1988 Newquist, HP. The Brain Makers, Sams Publishing, 1994. ISBN 0-672-30412-0 ), many now-commonplace technologies — including effective garbage collection, laser printing, windowing systems, computer mice, high-resolution bit-mapped graphics, computer graphic rendering, networking innovations and protocols like CHAOSNet — were commercially pioneered on Lisp machines. Several companies were building and selling Lisp Machines in the 1980s: Symbolics (3600, 3640, XL1200, MacIvory and other models), Lisp Machines Incorporated (LMI Lambda), Texas Instruments (Explorer and MicroExplorer) and Xerox (InterLisp-D workstations). The operating systems were written in Lisp Machine Lisp, InterLisp (Xerox) and later partly in Common Lisp. History Historical context Artificial intelligence (AI) computer programs of the 1960s and 1970s intrinsically required what was then considered a huge amount of computer power, as measured in processor time and memory space. The power requirements of AI research were exacerbated by the Lisp symbolic programming language, when commercial hardware was designed and optimized for assembly- and Fortran-like programming languages. At first, the cost of such computer hardware meant that it had to be shared among many users. But as integrated circuit technology shrank the size and cost of computers in the 1960s and early 1970s, and the memory requirements of AI programs started to exceed the address space of the most common research computer, the DEC PDP-10, researchers considered a new approach: a computer designed specifically to develop and run large artificial intelligence programs, and tailored to the semantics of the Lisp programming language. To keep the operating system (relatively) simple, these machines would not be shared, but would be dedicated to a single user. Initial development In 1973, Richard Greenblatt and Thomas Knight, programmers at MIT's AI Lab, started what would become the MIT Lisp Machine Project when they first began building a computer hardwired to run certain basic Lisp operations, rather than run them in software, in a 24-bit tagged architecture. The machine also did incremental (or "Arena") garbage collecting. More specifically, since Lisp variables are typed at runtime rather than compile time, a simple addition of two variables could take five times as long on conventional hardware, due to test and branch instructions. Lisp Machines ran the tests in parallel with the more conventional single instruction additions. If the simultaneous tests failed, then the result was discarded and recomputed; this meant in many cases a speed increase by several factors. This simultaneous checking approach was used as well in testing the bounds of arrays when referenced, and other memory management necessities (not merely garbage collection or arrays). Type checking was further improved and automated when the conventional byte word of 32-bits was lengthened to 36-bits for Symbolics 3600-model Lisp machines "Architecture of the Symbolics 3600", David A. Moon and eventually to 40-bits or more (usually, the excess bits not accounted for by the following were used for error-correcting codes). The first group of extra bits were used to hold type data, making the machine a tagged architecture, and the remaining bits were used to implement CDR coding (wherein the usual linked list elements are compressed to occupy roughly half the space), aiding garbage collection by reportedly an order of magnitude. A further improvement was two microcode instructions which specifically supported Lisp functions, reducing the cost of calling a function to (in some Symbolics implementations) as little as 20 clock cycles. The first machine was called the CONS machine (named after the list construction operator cons in Lisp). Often it was affectionately referred to as the "Knight machine", perhaps since Knight wrote his master's thesis on the subject; it was extremely well-received. It was subsequently improved into a version called CADR (a pun; in Lisp, the cadr function, which returns the second pointer of a cons cell, is pronounced "kay'-der" or "kah'-der", as some pronounce the word "cadre") which was based on essentially the same architecture. About 25 of what were essentially prototype CADRs were sold within and without MIT for ~$50,000; it quickly became the favorite machine for hacking- many of the most favored software tools were quickly ported to it (e.g. Emacs was ported from ITS in 1975). It was so well received at an AI conference held at MIT in 1978 that DARPA began funding its development. A fork In 1979, Russell Noftsker, convinced that Lisp machines had a bright future commercially due to the strength of the Lisp language and the enabling factor of hardware acceleration, made Greenblatt a proposal: they would take the technology commercial. In a counter-intuitive move for an AI Lab hacker, Greenblatt acquiesced, hoping perhaps that he could recreate the informal and productive atmosphere of the Lab in a real business, a bit like Apple Computer. These ideas and hopes were considerably different from the ones Noftsker held. The two negotiated at length, but neither would compromise. As the proposed company could only be a success with the full and undivided assistance of the AI Lab hackers as a group, Noftsker and Greenblatt decided that the fate of the enterprise was up to them, and so the choice should be left to the hackers. The ensuing discussions of the choice rent the lab into two factions. In February, 1979, matters came to a head. The hackers sided with Noftsker, believing that a commercial venture fund-backed company had a better chance of surviving and commercializing Lisp Machines than Greenblatt's proposed self-sustaining start-up. Greenblatt had lost the battle. It was at this juncture that Symbolics, Noftsker's enterprise, slowly came together. While Noftsker was paying his staff a salary, he didn't actually have a building or any equipment for the hackers to work on. He bargained with Patrick Winston that, in exchange for allowing Symbolics' staff to keep working out of MIT, Symbolics would let MIT use internally and freely all the software Symbolics developed. A consultant from CDC, who was trying to put together a natural language computer application with a group of West-coast programmers, came to Greenblatt, seeking a Lisp machine for his group to work with, about eight months after the disastrous conference with Noftsker. Greenblatt had decided to start his own rival Lisp machine company, but he had done nothing. The consultant, Alexander Jacobson, decided that the only way Greenblatt was going to actually start his company and build the Lisp machines that Jacobson desperately needed was if Jacobson pushed and otherwise helped Greenblatt launch his company. Jacobson pulled together business plans, a board, a partner for Greenblatt (one F. Stephen Wyle). The newfound company was named LISP Machine, Inc. (LMI), and was funded by CDC orders, via Jacobson. Around this time Symbolics (Noftsker's company) began operations — it had been hindered by Noftsker's promise to give Greenblatt a year's head start, and by severe delays in procuring venture capital. Symbolics still had the major advantage that while 3 or 4 of the AI Lab hackers had gone to work for Greenblatt, a solid 14 other hackers had signed onto Symbolics. There were two AI Lab people who did not get hired by either: Richard Stallman and Marvin Minsky. Stallman, however, blamed Symbolics for the decline of the hacker community that had centered around the AI lab. For two years, from 1982 to the end of 1983, Stallman worked by himself to clone the output of the Symbolics programmers, with the aim of preventing them from gaining a monopoly on the lab's computers. Levy,S: Hackers. Penguin USA, 1984 Regardless, after a series of internal battles, Symbolics did get off the ground in 1980/1981, selling the CADR as the LM-2, while Lisp Machines, Inc. sold it as the LMI-CADR. Symbolics did not intend to produce many LM-2s, since the 3600 family of Lisp machines was supposed to ship quickly, but the 3600s were repeatedly delayed, and Symbolics ended up producing ~100 LM-2s, each of which sold for $70,000. Both companies developed second-generation products based on the CADR: the Symbolics 3600 and the LMI-LAMBDA (of which LMI managed to sell ~200). The 3600, which shipped a year late, expanded on the CADR by widening the machine word to 36-bits, expanding the address space to 28-bits Moon 1985 , and adding hardware to accelerate certain common functions that were implemented in microcode on the CADR. The LMI-LAMBDA, which came out a year after the 3600, in 1983, was compatible with the CADR (it could run CADR microcode), but there were hardware differences. Texas Instruments (TI) joined the fray when it licensed the LMI-LAMBDA design and produced its own variant, the TI Explorer. Some of the LMI-LAMBDAs and the TI Explorer were dual systems with both a Lisp and a UNIX processor. Symbolics continued to develop the 3600 family and its operating system, Genera, and produced the Ivory, a VLSI implementation of the Symbolics architecture. Starting in 1987, several machines based on the Ivory processor were developed: boards for Suns and Macs, stand-alone workstations and even embedded systems (I-Machine Custom LSI, 32 bit address, Symbolics XL-400, UX-400, MacIvory II; in 1989 available platforms were Symbolics XL-1200, MacIvory III, UX-1200, Zora, NXP1000 "pizza box"). Texas Instruments shrunk the Explorer into silicon as the MicroExplorer which was offered as a card for the Apple Mac II. LMI abandoned the CADR architecture and developed its own K-Machine , but LMI went bankrupt before the machine could be brought to market. Prior to its demise, LMI was working on a distributed system for the LAMBDA using moby space. These machines had hardware support for various primitive Lisp operations (data type testing, CDR coding) and also hardware support for incremental garbage collection. They ran large Lisp programs very efficiently. The Symbolics machine was actually competitive against many commercial super mini computers, but it was never adapted for conventional purposes. The Symbolics Lisp Machines were also sold to some non-AI markets like computer graphics, modeling and animation. The MIT-derived Lisp machines ran a Lisp dialect called ZetaLisp, descended from MIT's Maclisp. The operating systems were written from the ground up in Lisp, often using object-oriented extensions. Later these Lisp machines also supported various versions of Common Lisp (with Flavors, New Flavors and CLOS). BBN developed its own Lisp Machine, called Jericho, which ran a version of Interlisp. It was never marketed; frustrated, the entire AI group resigned, and were hired primarily by Xerox. So, Xerox PARC had, simultaneous with Greenblatt's own development over at MIT, developed their own Lisp machines which were designed to run InterLisp (and later Common Lisp). The same hardware was used with different software also as Smalltalk machines and as an office system. These included the Xerox 1100, aka "Dolphin" (1979); the Xerox 1132, aka "Dorado"; the Xerox 1108, aka "Dandelion" (1981); and the Xerox 1109, aka "Dandetiger"; and the Xerox 1186/6085, aka "Daybreak". The Xerox machines were a commercial failure, but they did influence the creation of Apple Computer's Macintosh. The operating system of the Xerox Lisp Machines has also been ported to a virtual machine and is available for several platforms as a product called "Medley". The Xerox Lisp Machine was well known for its advanced development environment (InterLisp-D), the ROOMS window manager, for its early graphical user interface and for novel applications like NoteCards (one of the first Hypertext applications). A UK company, Racal-Norsk, attempted to repurpose Norsk Data superminis as microcoded Lisp Machines, running Symbolics' ZetaLisp software. There were several attempts by Japanese manufacturers to enter the Lisp Machine market, including the Fujitsu Facom-alpha mainframe co-processor (which was actually marketed as early as 1978), and several university research efforts that produced working prototypes as part of the Fifth Generation. With the onset of the "AI Winter" and the early beginnings of the "PC revolution" (which would gather steam and sweep away the minicomputer and workstation manufacturers), cheaper desktop PCs soon were able to run Lisp programs even faster than Lisp machines, without the use of special purpose hardware. Their high profit margin hardware business eliminated, most Lisp Machine manufacturers went out of business by the early 90s, leaving only software based companies like Lucid Inc. or hardware manufacturers who switched to software and services to avoid the crash. Besides Xerox, Symbolics is the only Lisp Machine company still operating today, selling the Open Genera Lisp Machine software environment as well as the Macsyma computer algebra system. In the late 90s, there were plans by Sun Microsystems and other companies to build language-specific computers for Java, similar in concept and execution to the Lisp machines.

7,769 | Amram | In the Book of Exodus, Amram (), is the father of Aaron, Moses, and Miriam and the husband of Jochebed . In the Bible In addition to being married to Jochebed, Amram is also described in the Bible as having been related to Jochebed prior to the marriage, although the exact relationship is uncertain; some Greek and Latin manuscripts of the Septuagint state that Jochebed was Amram's father's cousin, and others state that Amram was Jochebed's cousin Exodus 6:16-20, LXX - , but the Masoretic text states that he was Jochebed's nephew New American Bible, footnote to Exodus 6:20 . Textual scholars attribute the biblical genealogy to the Book of Generations, a document originating from a similar religiopolitical group and date to the priestly source Richard Elliott Friedman, Who Wrote The Bible? . According to biblical scholars, the Torah's genealogy for Levi's descendants, is actually an aetiological myth reflecting the fact that there were four different groups among the levites - the Gershonites, Kohathites, Merarites, and Aaronids Peake's commentary on the Bible ; Aaron - the eponymous ancestor of the Aaronids - couldn't be portrayed as a brother to Gershon, Kohath, and Merari, as the narrative about the birth of Moses (brother of Aaron), which textual scholars attribute to the earlier Elohist source, mentions only that both his parents were Levites (without identifying their names) . Biblical scholars suspect that the Elohist account offers both matrilinial and patrilinial descent from Levites in order to magnify the religious credentials of Moses. Family tree According to the Septuagint, Amram's family tree would be as follows: while according to the Masoretic text, Amram's family tree would be as follows: In rabbinical literature and apocryphal literature In the Apocryphal Testament of Levi, it is stated that Amram was born, as a grandson of Levi, when Levi was 64 years old Testament of the Patriarchs, Levi:12 . The Exodus Rabbah argues that when the Pharaoh instructed midwives to throw male children into the Nile, Amram divorced Jochebed, who was three months pregnant with Moses at the time, arguing that there was no justification for the Israelite men to father children if they were just to be killed Exodus Rabbah 1:17 ; however, the text goes on to state that Miriam, his daughter, chided him for his lack of care for his wife's feelings, persuading him to recant and marry Jochebed again. According to the Talmud, Amram promulgated the laws of marriage and divorce amongst the Jews in Egypt; the Talmud also argues that Amram had extreme longevity, which he used to ensure that doctrines were preserved through several generations Jewish Encyclopedia . Despite the legend of his divorce and remarriage, Amram was also held to have been entirely sinless throughout his life, and was rewarded for this by his corpse remaining without any signs of decay Baba Batra 17a . Prior to his death, according to the Book of Jubilees, Amram was among those who went to Egypt and recovered the bones of the sons of his grandfather and great uncles (excluding those of Joseph which had already been brought to Canaan), so that they could be reburied in the cave of Machpelah Jubilees 46:11 . The text states that this recovery was opportunistically performed when a war broke out between Egypt and Canaan ibid . One of the Dead Sea Scrolls (4Q535, Manuscript B) is written from Amram's point of view, and hence has been dubbed the Testament of Amram. The document is dated to the 2nd century BC and, in the form of a vision, briefly discusses dualism and the Watchers: I saw Watchers in my vision, the dream-vision. Two men were fighting over me ... holding a great contest over me. I asked them, 'Who are you, that you are thus empowered over me?' They answered, 'We have been empowered and rule over all mankind.' They said to me, 'Which of us do you choose to rule you?' I raised my eyes and looked. One of them was terrifying in his appearance, like a serpent, his cloak, many-colored yet very dark. ... And I looked again, and in his appearance, his visage like a viper. ... I replied to him, 'This Watcher, who is he?' He answered, 'This Watcher ... his three names are Belial and Prince of Darkness and King of Evil.' I said (to the other Watcher), 'My lord, what dominion (have you?)' He answered, 'You saw (the viper), and he is empowered over all Darkness, while I (am empowered over all Light.) ... My three names are Michael, Prince of Light and King of Righteousness. translation by Prof. Robert Eisenman References | Amram |@lemmatized book:3 exodus:5 amram:14 father:3 aaron:3 moses:4 miriam:2 husband:1 jochebed:8 bible:5 addition:1 marry:2 also:3 describe:1 relate:1 prior:2 marriage:2 although:1 exact:1 relationship:1 uncertain:1 greek:1 latin:1 manuscript:2 septuagint:2 state:6 cousin:2 others:1 lxx:1 masoretic:2 text:4 nephew:1 new:1 american:1 footnote:1 textual:2 scholar:4 attribute:2 biblical:3 genealogy:2 generation:2 document:2 originate:1 similar:1 religiopolitical:1 group:2 date:2 priestly:1 source:2 richard:1 elliott:1 friedman:1 write:2 accord:5 torah:1 levi:5 descendant:1 actually:1 aetiological:1 myth:1 reflect:1 fact:1 four:1 different:1 among:2 levite:3 gershonites:1 kohathites:1 merarites:1 aaronids:2 peake:1 commentary:1 eponymous:1 ancestor:1 portray:1 brother:2 gershon:1 kohath:1 merari:1 narrative:1 birth:1 early:1 elohist:2 mention:1 parent:1 without:2 identify:1 name:3 suspect:1 account:1 offer:1 matrilinial:1 patrilinial:1 descent:1 order:1 magnify:1 religious:1 credential:1 family:3 tree:3 would:2 follow:2 rabbinical:1 literature:2 apocryphal:2 testament:3 bear:1 grandson:1 year:1 old:1 patriarch:1 rabbah:2 argue:3 pharaoh:1 instruct:1 midwife:1 throw:1 male:1 child:2 nile:1 divorce:3 three:3 month:1 pregnant:1 time:1 justification:1 israelite:1 men:2 kill:1 however:1 go:2 daughter:1 chide:1 lack:1 care:1 wife:1 feeling:1 persuade:1 recant:1 talmud:2 promulgate:1 law:1 amongst:1 jew:1 egypt:3 extreme:1 longevity:1 use:1 ensure:1 doctrine:1 preserve:1 several:1 jewish:1 encyclopedia:1 despite:1 legend:1 remarriage:1 hold:2 entirely:1 sinless:1 throughout:1 life:1 reward:1 corpse:1 remain:1 sign:1 decay:1 baba:1 batra:1 death:1 jubilee:2 recover:1 bone:1 son:1 grandfather:1 great:2 uncle:1 exclude:1 joseph:1 already:1 bring:1 canaan:2 could:1 reburied:1 cave:1 machpelah:1 recovery:1 opportunistically:1 perform:1 war:1 break:1 ibid:1 one:2 dead:1 sea:1 scroll:1 b:1 point:1 view:1 hence:1 dub:1 century:1 bc:1 form:1 vision:3 briefly:1 discus:1 dualism:1 watcher:5 saw:2 dream:1 two:1 fight:1 contest:1 ask:1 thus:1 empower:4 answer:3 rule:2 mankind:1 say:2 u:1 choose:1 raise:1 eye:1 look:2 terrify:1 appearance:2 like:2 serpent:1 cloak:1 many:1 colored:1 yet:1 dark:1 visage:1 viper:2 reply:1 belial:1 prince:2 darkness:2 king:2 evil:1 lord:1 dominion:1 light:2 michael:1 righteousness:1 translation:1 prof:1 robert:1 eisenman:1 reference:1 |@bigram masoretic_text:2 elliott_friedman:1 divorce_remarriage:1 |
7,770 | Limited-stop | Limited-stop bus, tram or train services omit calls at certain stops in order to offer a faster trip between the places served. The term is normally used on routes with a mixture of fast and slow services. Additionally there may be a "semi-fast" service with more stops than a "fast" service, but fewer than a "slow" service. On railways, the layout of the tracks and number/length of platforms at stations will normally limit the extent to which a blend of fast/semi-fast/slow services can be operated. In a typical metropolitan area limited-stop services are most likely to be scheduled at times when more people are travelling, not limited to the Rush Hour. Leisure and shopping trips tend to be more localised and geographically varied, thus requiring and responding to slower services calling at most stops along the route. In heavily congested traffic conditions a bus scheduled as fast or semi-fast may not always achieve an appreciably faster journey than a stopping service along the same route, unless there are special bus lanes. Sometimes a higher (premium) fare may be required for the faster journey, especially for some international trains in western Europe. In Australia, particularly in Brisbane and Sydney, limited stop services are formed by commuter trains which run as limited stops or express services from the city centre to the edge of the suburban area and then as all stops in the interurban area. Same is done in Helsinki, Finland by VR commuter rail.

7,771 | Nucleon | In physics, a nucleon is a collective name for two baryons: the neutron and the proton. They are constituents of the atomic nucleus and until the 1960s were thought to be elementary particles. In those days their interactions (now called internucleon interactions) defined strong interactions. Now they are known to be composite particles, made of quarks. Understanding the nucleons' properties is one of the major goals of quantum chromodynamics, the modern theory of strong interactions. The proton is the lightest baryon and its stability is a measure of baryon number conservation. The proton's lifetime thus puts strong constraints on speculative theories which try to extend the Standard Model of particle physics. The neutron decays into a proton through the weak interaction. The two are members of an isospin doublet (). The proton With spin and positive parity (often shortened to ), a charge of +1 e, and rest mass of , the proton is the nucleus of the hydrogen-1 atom (1H). It has a magnetic moment, denoted μp, of . The predicted electric dipole moment is zero, consistent with the experimentally found upper bound value which is less than , for example, from NMR measurements. A proton is made up of three quarks (two up quarks and one down quark), held together by the strong force, which is mediated by gluons. In some speculative grand unified theories it may decay with a half-life equal to that of the Universe. The half-life for this decay has been thus limited to be greater than . The charge radius is measured mainly through elastic electron-proton scattering and is . For specific decay modes, into leptons or antileptons and a meson, the bound state is predicted to be longer lived than 1032 years. The proton is therefore taken to be a stable particle, and the baryon number is thus assumed to be conserved. The neutron The neutron has no net electrical charge; it does however have a (dipolar) magnetic moment μn , spin, parity of +, and a rest mass of . Like the proton, a neutron is made up of three fractional-charge quarks (in this case one up quark of charge + e and two down quarks of charge − e, whose total charge is zero), that are being held together by the strong nuclear force. It decays weakly through the process → + + The most precise measurements of its decay lifetime are mainly from traps of various kinds and in beams. The lifetime of a free neutron outside the nucleus is (about 15 minutes). Its magnetic moment is . Both time reversal and parity invariance of the strong interactions implies that the neutron's electric dipole moment must be zero; the current observational bound is that it is less than . The mean-square charge radius, related to the scattering length, measured in low energy electron-neutron scattering for the neutron is . Violation of the conservation of baryon number (B) may give rise to oscillations between the neutron and antineutron, through processes which change B by two units. Using free neutrons from nuclear reactors, as well as neutrons bound inside nuclei, the mean time for these transitions is found to be greater than . The much poorer bound, as compared to protons, is related to the difficulty of the observations. A limit on electric charge non-conservation comes from the observed lack of the decay The observations which limit the branching fraction of the neutron in this decay channel to less than are all done looking for appropriate decays of nuclei ( and ). Antinucleons CPT-symmetry puts strong constraints on the relative properties of particles and antiparticles and, therefore, is open to stringent tests. For example, the absolute value of the proton and antiproton charges have to be equal. This equality has been tested to one part in 108. The equality of their masses is also tested to 10−8. By holding antiprotons in a Penning trap, the equality of the charge to mass ratio of the proton has been tested to . The magnetic moment of the antiproton is found to be equal and opposite to that of the proton. For the neutron-antineutron system, the masses are equal to within a factor of . Quark model classification In the quark model with SU(2) flavour, the two nucleons are part of the ground state doublet. The proton has quark content of uud, and the neutron, udd. In SU(3) flavour, they are part of the ground state octet (8) of spin baryons, known as the Eightfold way. The other members of this octet are the hyperons strange isotriplet , , , the and the strange isodoublet , . One can extend this multiplet in SU(4) flavour (with the inclusion of the charm quark) to the ground state 20-plet, or to SU(6) flavour (with the inclusion of the top and bottom quarks) to the ground state 56-plet. The article on isospin provides an explicit expression for the nucleon wave functions in terms of the quark flavour eigenstates. Models of the nucleon Although it is known that the nucleon is made from three quarks, , it is not known how to solve the equations of motion for quantum chromodynamics. Thus, the study of the low-energy properties of the nucleon are performed by means of models. The only first-principles approach available is to attempt to solve the equations of QCD numerically, using lattice QCD. This requires complicated algorithms and very powerful supercomputers. However, several analytic models also exist: The Skyrmion models the nucleon as a topological soliton in a non-linear SU(2) pion field. The topological stability of the Skyrmion is interpreted as the conservation of baryon number, that is, the non-decay of the nucleon. The local topological winding number density is identified with the local baryon number density of the nucleon. With the pion isospin vector field oriented in the shape of a hedgehog, the model is readily solvable, and is thus sometimes called the hedgehog model. The hedgehog model is able to predict low-energy parameters, such as the nucleon mass, radius and axial coupling constant, to approximately 30% of experimental values. The MIT bag model confines three non-interacting quarks to a spherical cavity, with the boundary condition that the quark vector current vanish on the boundary. The non-interacting treatment of the quarks is justified by appealing to the idea of asymptotic freedom, whereas the hard boundary condition is justified by quark confinement. Mathematically, the model vaguely resembles that of a radar cavity, with solutions to the Dirac equation standing in for solutions to the Maxwell equations and the vanishing vector current boundary condition standing for the conducting metal walls of the radar cavity. If the radius of the bag is set to the radius of the nucleon, the bag model predicts a nucleon mass that is within 30% of the actual mass. An important failure of the basic bag model is its failure to provide a pion-mediated interaction. The chiral bag model merges the MIT bag model and the Skyrmion model. In this model, a hole is punched out of the middle of the Skyrmion, and replaced with a bag model. The boundary condition is provided by the requirement of continuity of the axial vector current across the bag boundary. Very curiously, the missing part of the topological winding number (the baryon number) of the hole punched into the Skyrmion is exactly made up by the non-zero vacuum expectation value (or spectral asymmetry) of the quark fields inside the bag. , this remarkable trade-off between topology and the spectrum of an operator does not have any grounding or explanation in the mathematical theory of Hilbert spaces and their relationship to geometry. Several other properties of the chiral bag are notable: it provides a better fit to the low energy nucleon properties, to within 5–10%, and these are almost completely independent of the chiral bag radius (as long as the radius is less than the nucleon radius). This independence of radius is referred to as the Cheshire Cat principle, after the fading to a smile of Lewis Carroll's Cheshire Cat. It is expected that a first-principles solution of the equations of QCD will demonstrate a similar duality of quark-pion descriptions.

7,772 | James_Blish | James Benjamin Blish (East Orange, New Jersey, May 23, 1921 – Henley-on-Thames, July 30, 1975) was an American author of fantasy and science fiction. Blish also wrote literary criticism of science fiction using the pen-name William Atheling Jr. Biography In the late 1930s to the early 1940s, Blish was a member of the Futurians. Blish trained as a biologist at Rutgers and Columbia University, and spent 1942–1944 as a medical technician in the U.S. Army. After the war he became the science editor for the Pfizer pharmaceutical company. His first published story appeared in 1940, and his writing career progressed until he gave up his job to become a professional writer. He is credited with coining the term gas giant, in the story "Solar Plexus" as it appeared in the anthology Beyond Human Ken, edited by Judith Merril. (The story was originally published in 1941, but that version did not contain the term; Blish apparently added it in a rewrite done for the anthology, which was first published in 1952.) Blish was married to the literary agent Virginia Kidd from 1947 to 1963. From 1962 to 1968, he worked for the Tobacco Institute http://www.blish.org/gens/1380I.html James Benjamin Blish, B.Sc., Ed. genealogy page . Between 1967 and his death from lung cancer in 1975, Blish became the first author to write short story collections based upon the classic TV series Star Trek. In total, Blish wrote 11 volumes of short stories adapted from episodes of the 1960s TV series, as well as an original novel, Spock Must Die! in 1970 — the first original novel for adult readers based upon the series (since then hundreds more have been published). He died midway through writing Star Trek 12; his wife, J. A. Lawrence, completed the book, and later completed the adaptations in the volume Mudd's Angels. Blish lived in Milford, Pennsylvania at Arrowhead until the mid-1960s. In 1968, Blish emigrated to England, and lived in Oxford until his death in 1975. He is buried in Holywell Cemetery, Oxford, near the grave of Kenneth Grahame. Works Cities in Flight Perhaps Blish's most famous works were the "Okies" stories, known collectively as Cities in Flight, published in the science-fiction digest magazine Astounding Science Fiction. The framework for these was set in the first of four novels, They Shall Have Stars, which introduces two essential features of the series. The first is the invention of the anti-aging drug ascomycin; Blish's employer Pfizer makes a thinly disguised appearance as Pfitzner in a section showing the screening of biological samples for interesting activity. (Pfizer also appears in disguise as one of the sponsors of the polar expedition in a subsequent book, Fallen Star). The second is the development of an antigravity device known as the "spindizzy". Since the device becomes more efficient when used to propel larger objects, entire cities leave an Earth in decline and rove the stars, looking for work among less-industrialized systems. The long life provided by ascomycin is necessary because the journeys between stars are time-consuming. They Shall Have Stars is dystopian science fiction of a type common in the era of McCarthyism. The second, A Life For The Stars, is a coming of age story set amid flying cities. The third, Earthman, Come Home, is a series of loosely connected short stories detailing the adventures of a flying New York City; it was selected as one of the best novellas prior to 1965 by the Science Fiction Writers of America and as such, was reprinted in The Science Fiction Hall of Fame, Volume Two. For his fourth and final installment, The Triumph of Time (UK title: A Clash of Cymbals), Blish set the end of his literature's universe in 4004 AD. Choosing 4004 AD is a satirical reference to the year "4004 BC", inferred by Bishop James Ussher to be the year of the creation of the universe, based on his study of the Book of Genesis. (The chronology in early editions of They Shall Have Stars differed somewhat from the later reprints, indicating that Blish, or his editors, may not have planned this at the beginning of the series.) A film version of Cities in Flight was in pre-production by Spacefilms in 1979, but never materialized. After Such Knowledge Blish declared that another group of novels was a trilogy, each dealing with an aspect of the price of knowledge, and given the overall name of "After Such Knowledge" (the title taken from a T. S. Eliot quote). The first published, A Case of Conscience (a winner of the 1959 Hugo Award as well as 2004/1953 Retrospective Hugo Award for Best Novella), showed a Jesuit priest confronted with an alien intelligent race, apparently unfallen, which he eventually concludes must be a Satanic fabrication. The second, Doctor Mirabilis, is a historical novel about the medieval proto-scientist Roger Bacon. The third, actually two very short novels, Black Easter and The Day after Judgement, was written using the assumption that the ritual magic for summoning demons as described in grimoires actually worked. The Seedling Stars (Pantropy) Blish's most famous short stories are the "Pantropy" tales, collected in the book The Seedling Stars. In these stories, humans are modified to live in various alien environments, this being easier and vastly cheaper than terraforming. Book One (Seeding Program) is about the inception of Pantropy, when the Pantropy program appears to have deteriorated into hideous genetic experimenting and has been outlawed. It describes Sweeney, a modified ("adapted") human whose metabolism is based on liquid ammonia and sulphur bonds and whose bones are made from ice IV, who is inserted into a colony on Ganymede by the Terran Port Authority (a para-military organization) to capture a renegade scientist and end his plans to seed modified humans on distant worlds. However, the government really only tries to derail pantropy because it will cut their profits from terraforming attempts. Sweeney is surprised to find a well established, functioning community on Ganymede and eventually realizes that he was just used as an expendable agent and that he has been fed false hopes about the possibility of being changed into a normal human being who could live on earth. Having found a real home, he switches sides and with his help the Ganymede colony manages to launch their seed ships to secret destinations, beyond the reach of the corrupt government. Book Two (The Thing in the Attic) depicts a very successful seeding project. It tells the story of a small group of intellectuals from a primitive culture of modified monkey-like humans living in the trees of their jungle world. Having openly voiced the opinion that the godly giants do not literally exist as put down in the book of laws, they are banished from the treetops for heresy. In their exile on the ground they have to adapt to vastly different circumstances, fight monsters resembling dinosaurs, and finally happen upon the godly giants - who turn out to be human scientists who have just arrived on the world to monitor the progress of the local adapted humans. The protagonists are told by the scientists that their whole race must eventually leave the treetops to conquer their world and that they have become pioneers of some sort for accomplishing survival. Book Three (Surface Tension) gives another example of a culture of adapted humans: A pantropy starship crashes on an ocean world, Hydrot, which is on orbit around Tau Ceti. With no hope for rescue, the few survivors modify their own genetic material to seed tiny aquatic "humans" into the lakes and puddles of the world and leave them a message engraved in tiny metal plates. The story then tells how over many seasons, the adapted human newcomers explore their aquatic environment, make alliances, invent tools, fight wars with hostile beings and finally gain dominance over the sentient beings of their world. They develop new technologies and manage to decipher some of the message on the metal plates. Finally they build a wooden "space ship" (which turns out to be two inches long) to overcome the surface tension and travel to "other worlds" - the next puddle - in search of their ancestry, as they have come to realize that they are not native to their world. Book Four (Watershed) takes a look at the more distant future. A very long time after the beginning of the Pantropy program, a starship crewed by "standard" humans is enroute to some unimportant backwater planet to deliver a pantropy team who are "adapted" humans resembling seals more than humans. Due to racial prejudices, tension mounts between the crew and the passengers onboard. When the captain decides to restrict the passengers to their cabins to prevent the situation from escalating, the leader of the adapted humans informs him that the planet ahead is Earth, where the "normal" human form once developed. He challenges the "normal" humans to follow him onto the surface of their ancestral home planet and prove that they are superior to the "adapted" seal people who will now be seeded there - or admit that they were beaten on their own grounds. The story concludes as the captain and his lieutenant silently ponder the possibility that they, being "standard" humans, are just a minority, and an obsolete species. (The German title of the anthology is Auch sie sind Menschen..., literally "They, too, are humans". The stories' titles are Aussaatplan, Himmel und Hölle, Oberflächenspannung and Rückkehr respectively, which would literally translate back into English as "Seeding plan", "Heaven and Hell", "Surface tension" and "Return" or "Homecoming". However, except for Surface Tension the original English titles seem to be different.) Other Blish collaborated with Norman L. Knight on a series of stories set in a world with a population a thousand times that of today, and followed the efforts of those keeping the system running, collected in one volume as A Torrent of Faces. Included in this collection is Blish's Nebula-nominated novella 'The Shipwrecked Hotel' - a story about a semi-submerged hotel with approximately a million guests which experiences a massive computer failure (a result of escaped silverfish) and begins to sink. Running parallel to all the side-plots is the inevitable catastrophe of the mile-wide asteroid 'Flavia' striking near the east coast of the USA. The stories are also notable for including a form of pantropy that has been used to modify humans into a sea-dwelling form known as 'Tritons'. James Blish's grave marker.

7,773 | Folie_à_deux | Folie à deux (translated, "a madness shared by two") is a rare psychiatric syndrome in which a symptom of psychosis (particularly a paranoid or delusional belief) is transmitted from one individual to another. The same syndrome shared by more than two people may be called folie à trois, folie à quatre, folie à famille or even folie à plusieurs ("madness of many"). Recent psychiatric classifications refer to the syndrome as shared psychotic disorder (DSM-IV) (297.3) and induced delusional disorder (folie à deux) (F.24) in the ICD-10, although the research literature largely uses the original name. Presentation This case study is taken from Enoch and Ball's 'Uncommon Psychiatric Syndromes' (2001, p181): Margaret and her husband Michael, both aged 34 years, were discovered to be suffering from folie à deux when they were both found to be sharing similar persecutory delusions. They believed that certain persons were entering their house, spreading dust and fluff and "wearing down their shoes". Both had, in addition, other symptoms supporting a diagnosis of paranoid psychosis, which could be made independently in either case. This syndrome is most commonly diagnosed when the two or more individuals concerned live in proximity and may be socially or physically isolated and have little interaction with other people. Various sub-classifications of folie à deux have been proposed to describe how the delusional belief comes to be held by more than one person. Folie imposée is where a dominant person (known as the 'primary', 'inducer' or 'principal') initially forms a delusional belief during a psychotic episode and imposes it on another person or persons (known as the 'secondary', 'acceptor' or 'associate') with the assumption that the secondary person might not have become deluded if left to their own devices. If the parties are admitted to hospital separately then the delusions in the person with the induced beliefs usually resolve without the need of medication. Folie simultanée describes the situation where two people, considered to independently suffer from psychosis, influence the content of each other's delusions so they become identical or strikingly similar. Folie à deux and its more populous cousins are in many ways a psychiatric curiosity. The current Diagnostic and Statistical Manual of Mental Disorders states that a person cannot be diagnosed as being delusional if the belief in question is one "ordinarily accepted by other members of the person's culture or subculture" (see entry for delusion). It is not clear at what point a belief considered to be delusional escapes from the folie à... diagnostic category and becomes legitimate because of the number of people holding it. When a large number of people may come to believe obviously false and potentially distressing things based purely on hearsay, these beliefs are not considered to be clinical delusions by the psychiatric profession and are labelled instead as mass hysteria. Being defined as a rare pathological manifestation, folie à deux is rarely found in general psychology or social psychology text books, and is relatively unknown outside abnormal psychology, psychiatry, and psychopathology. Related phenomena There have been reports that a similar phenomenon to folie à deux had been induced by the military incapacitating agent BZ in the late 60s, and most recently again by anthropologists in the South American rainforest consuming the hallucinogen ayahuasca (Metzner, 1999) See also Delusion Delusional disorder Psychosis Further reading Halgin, R. & Whitbourne, S.

7,774 | Economy_of_Guinea | Guinea is richly endowed with minerals, possessing an estimated one-third of the world's proven reserves of bauxite, more than 1.8 billion metric tons of high-grade iron ore, significant diamond and gold deposits, and undetermined quantities of uranium. Guinea also has considerable potential for growth in the agricultural and fishing sectors. Land, water, and climatic conditions provide opportunities for large-scale irrigated farming and agroindustry.Remittances from Guineans living and working abroad and coffee exports account for the rest of Guinea's foreign exchange. Current GDP per capita of Guinea shrank by 16% in the Nineties. History Since 1985, the Guinean Government has adopted policies to return commercial activity to the private sector, promote investment, reduce the role of the state in the economy, and improve the administrative and judicial framework. The government has eliminated restrictions on agricultural enterprise and foreign trade, liquidated many parastatals, increased spending on education, and vastly downsized the civil service. The government also has made major strides in restructuring the public finances. Guinea's exports in 2006 The IMF and the World Bank are heavily involved in the development of Guinea's economy, as are many bilateral donor nations, including the United States. Guinea's economic reforms have had recent notable success, improving the rate of economic to 5% and reducing the rate of inflation to about 2%, as well as increasing government revenues while restraining official expenditures. Although Guinea's external debt burden remains high, the country is now current on external debt payments. The government revised the private investment code in 1998 to stimulate economic activity in the spirit of a free enterprise. The code does not discriminate between foreigners and nationals and provides for repatriation of profits. Foreign investments outside Conakry are entitled to especially favorable conditions. A national investment commission has been formed to review all investment proposals. The United States and Guinea have signed an investment guarantee agreement that offers political risk insurance to American investors through OPIC. Guinea plans to inaugurate an arbitration court system to allow for the quick resolution of commercial disputes. Average wages in 2007 hover around $2-3 per day. Mining Bauxite mining and alumina production provide about 80% of Guinea's foreign exchange. Several U.S. companies are active in this sector. Diamonds and gold also are mined and exported on a large scale, providing additional foreign exchange. Concession agreements have been signed for future exploitation of Guinea's extensive iron ore deposits. Guinea is richly endowed with minerals, possessing an estimated one-third of the world's proven reserves of bauxite, more than 1.8 billion metric tons (MT) of high-grade iron ore, significant diamond and gold deposits, and undetermined quantities of uranium. Lately, with the increase of alumina demand thanks to booming China, there is a renew interest in Guinea riches. The consortium Alcan and Alcoa, partner with the Guinean government in the CBG mining in north western Guinea, have announced the feasibility study for the construction of a 1 million TPa alumina smelter. This come with a similar project from Canadian start-up Global Alumina trying to come with 2 billions dollars alumina plant in the same region. As of April 2005, the National Assembly of Guinea has not ratified Global's project. Agriculture Guinea also has considerable potential for growth in the agricultural and fishing sectors. Land, water, and climatic conditions provide opportunities for large-scale irrigated farming and agroindustry. Possibilities for investment and commercial activities exist in all these areas, but Guinea's poorly developed infrastructure continues to present obstacles to investment projects.

7,775 | Ken_Kesey | Kenneth Elton Kesey (; September 17, 1935 – November 10, 2001) was an American author, best known for his novel One Flew Over the Cuckoo's Nest (1962), OBITUARY: Ken Kesey | Independent, The (London) | Find Articles at BNET.com and as a counter-cultural figure who considered himself a sort-of link between the Beat Generation of the 1950s and the hippies of the 1960s. "I was too young to be a beatnik, and too old to be a hippie," Kesey said in a 1999 interview with Robert K. Elder. Early life Ken Kesey was born in La Junta, Colorado to dairy farmers Frederick A. Kesey and Geneva Smith. Lehmann-Haupt, Christopher. "Ken Kesey, Author of 'Cuckoo's Nest,' Who Defined the Psychedelic Era, Dies at 66". The New York Times (November 11, 2001). Retrieved on February 21, 2008. In 1946, the family moved to Springfield, Oregon. A champion wrestler in both high school and college, he graduated from Springfield High School in 1953. In 1956, while attending college at the University of Oregon in neighboring Eugene, Kesey eloped with his high-school sweetheart, Norma "Faye" Haxby, whom he had met in seventh grade. They had three children, Jed, Zane, and Shannon; Kesey had another child, Sunshine, in 1966 with fellow Merry Prankster Carolyn Adams. Kesey attended the University of Oregon's School of Journalism, where he received a degree in speech and communication in 1957, where he was also a brother of Beta Theta Pi. He was awarded a Woodrow Wilson National Fellowship in 1958 to enroll in the creative writing program at Stanford University, which he did the following year. While at Stanford, he studied under Wallace Stegner and began the manuscript that would become One Flew Over the Cuckoo's Nest. Experimentation with psychoactive drugs At Stanford in 1959, Kesey volunteered to take part in a CIA-financed study named Project MKULTRA at the Menlo Park Veterans Hospital. The project studied the effects of psychoactive drugs, particularly LSD, psilocybin, mescaline, cocaine, AMT, and DMT on people. Kesey wrote many detailed accounts of his experiences with these drugs, both during the Project MKULTRA study and in the years of private experimentation that followed. Kesey's role as a medical guinea pig inspired him to write One Flew Over the Cuckoo's Nest in 1962. The success of this book, as well as the sale of his residence at Stanford, allowed him to move to La Honda, California, in the mountains south of San Francisco. He frequently entertained friends and many others with parties he called "Acid Tests" involving music (such as Kesey's favorite band, The Warlocks, later known as the Grateful Dead), black lights, fluorescent paint, strobes and other "psychedelic" effects, and, of course, LSD. These parties were noted in some of Allen Ginsberg's poems and are also described in Tom Wolfe's The Electric Kool-Aid Acid Test, as well as Hell's Angels: The Strange and Terrible Saga of the Outlaw Motorcycle Gangs by Hunter S. Thompson and Freewheelin Frank, Secretary of the Hell's Angels by Frank Reynolds. Ken Kesey was also said to have experimented with LSD with Ringo Starr in 1965 and in fact influenced the set up for their future performances in the UK. One Flew Over the Cuckoo's Nest In 1959, Kesey wrote Zoo, a novel about the beatniks living in the North Beach community of San Francisco, but it was never published. In 1960, he wrote End of Autumn, about a young man who leaves his working class family after he gets a scholarship to an Ivy League school, also unpublished. The inspiration for One Flew Over the Cuckoo's Nest came while working on the night shift (with Gordon Lish) at the Menlo Park Veterans' Hospital. There, Kesey often spent time talking to the patients, sometimes under the influence of the hallucinogenic drugs with which he had volunteered to experiment. Kesey did not believe that these patients were insane, rather that society had pushed them out because they did not fit the conventional ideas of how people were supposed to act and behave. Published in 1962, it was an immediate success; in 1963, it was adapted into a successful stage play by Dale Wasserman; in 1975, Miloš Forman directed a screen adaptation, which won the "Big Five" Academy Awards: Best Picture, Best Actor (Jack Nicholson), Best Actress (Louise Fletcher), Best Director (Forman) and Writing Adapted Screenplay (Lawrence Hauben, Bo Goldman). Kesey was originally involved in creating the film, but left two weeks into production. He claimed never to have seen the movie because of a dispute over the $20,000 he was initially paid for the film rights. Kesey loathed the fact that, unlike the book, the film was not narrated by the Chief Bromden character, and he disagreed with Jack Nicholson being cast as Randle McMurphy (he wanted Gene Hackman). Despite this, Faye Kesey has stated that Ken was generally supportive of the film and pleased that it was made. Merry Pranksters When the publication of his second novel, Sometimes a Great Notion in 1964 required his presence in New York, Kesey, Neal Cassady, and others in a group of friends they called the "Merry Pranksters" took a cross-country trip in a school bus nicknamed "Furthur." NMAH | Signboard, Pass the Acid Test This trip, described in Tom Wolfe's The Electric Kool-Aid Acid Test (and later in Kesey's own screenplay "The Further Inquiry") was the group's attempt to create art out of everyday life. In New York, Cassady introduced Kesey to Jack Kerouac and Allen Ginsberg, who in turn introduced them to Timothy Leary. Sometimes a Great Notion was made into a 1971 film starring Paul Newman; it was nominated for two Academy Awards, and in 1972 was the first film shown by the new television network HBO, in Wilkes-Barre, Pennsylvania. Legal trouble Kesey was arrested for possession of marijuana in 1965. In an attempt to mislead police, he faked suicide by having friends leave his truck on a cliffside road near Eureka, along with a suicide note that read, "Ocean, Ocean I'll beat you in the end." Kesey fled to Mexico in the back of a friend's car. When he returned to the United States eight months later, Kesey was arrested and sent to the San Mateo County jail in Redwood City, California, for five months. On his release, he moved back to the family farm in Pleasant Hill, Oregon, in the Willamette Valley, where he spent the rest of his life. He wrote many articles, books (mostly collections of his articles), and short stories during that time. Twister In 1994 he toured with members of the Merry Pranksters performing a musical play he wrote about the millennium called Twister: A Ritual Reality. Many old and new friends and family showed up to support the Pranksters on this tour that took them from Seattle's Bumbershoot, all along the West Coast including a sold out two-night run at The Fillmore in San Francisco to Boulder, Colorado, where they coaxed (or pranked) the Beat Generation poet Allen Ginsberg into performing with them. Kesey, always a friend to musicians since his days of the Acid Test, enlisted the band Jambay, one of the original bands of the jam band genre, to be his "pit orchestra." Jambay played an acoustic set before each Twister performance and an electric set after each show. Final years Statue of Ken Kesey in Eugene, Oregon. Kesey mainly kept to his home life in Pleasant Hill, preferring to make artistic contributions on the Internet, or holding ritualistic revivals in the spirit of the Acid Test. He occasionally made appearances at rock concerts and festivals, bringing the second bus "Furthur2" and various Pranksters with him. In the official Grateful Dead DVD release The Closing of Winterland (2003), which documents the monumental New Year's '78 concert, Kesey is featured in a between-set interview. More notably, he appeared at the Hog Farm Family Pig-Nic Festival (organized by Woodstock MC Wavy Gravy, in Laytonville, California), where they mock-canonized a very ill but still quite aware Dr. Timothy Leary atop "Furthur2". He also performed on stage with Jambay at the Pig-Nic, playing a few songs from Twister with members of the original cast. In 1984, Kesey's son Jed, a wrestler for the University of Oregon, was killed on the way to a wrestling tournament when the team's bald-tired van crashed. This deeply affected Kesey, who later said Jed was a victim of conservative, anti-government policy that starved the team of proper funding. There is a memorial dedicated to Jed on the top of Mount Pisgah, which is near the Keseys' home in Pleasant Hill. In a Grateful Dead Halloween concert just days after Bill Graham died in a helicopter crash, Kesey appeared on stage in a tuxedo to deliver a eulogy, mentioning that Graham had paid for Jed's mountain-top memorial. In June 2001, Kesey was invited and accepted as the keynote speaker at the annual commencement of The Evergreen State College. His last major work was an essay for Rolling Stone magazine calling for peace in the aftermath of the September 11, 2001 attacks. In 1997, health problems began to take their toll on Kesey, starting with a stroke that year. After developing diabetes, he then needed surgery on his liver to remove a tumor on October 25, 2001. Ken Kesey never recovered from the operation and died on November 10, 2001, at the age of 66. Works Some of Kesey's better-known works include: One Flew Over the Cuckoo's Nest (1962, novel) Genesis West: Volume Five (1963, magazine article) Sometimes a Great Notion (1964, novel) Kesey's Garage Sale (1973, collection of essays) Demon Box (1986, collection of short stories) Caverns (1989, novel) The Further Inquiry (1990, play) Sailor Song (1992, novel) Last Go Round (1994, novel, written with Ken Babbs) Twister (1994, play) Kesey's Jail Journal (2003, collection of essays) Portrayals of Ken Kesey Neal Cassady, starring Tate Donovan as Cassady, and Chris Bauer as Kesey.

7,776 | Bernoulli_number | In mathematics, the Bernoulli numbers are a sequence of rational numbers with deep connections to number theory. They are closely related to the values of the Riemann zeta function at negative integers. In Europe, they were first studied by Jakob Bernoulli, after whom they were named by Abraham de Moivre. In Japan, perhaps earlier, they were independently discovered by Seki Kōwa. They appear in the Taylor series expansions of the tangent and hyperbolic tangent functions, in the Euler–Maclaurin formula, and in expressions for certain values of the Riemann zeta function. In note G of Ada Lovelace's notes on the Analytical Engine from 1842, Lovelace describes an algorithm for generating Bernoulli numbers with Babbage's machine Note G in the Menabrea reference . As a result, the Bernoulli numbers have the distinction of being the subject of the first computer program. Introduction The Bernoulli numbers Bn, sometimes denoted bn. were first discovered in connection with the closed forms of the sums for various fixed values of n. The closed forms are always polynomials in m of degree n + 1. The coefficients of these polynomials are closely related to the Bernoulli numbers, in connection with Faulhaber's formula: For example, taking n to be 1, Generating functions The Bernoulli numbers may also be defined using generating functions. Their exponential generating function is x/(ex − 1), so that: for all values of x of absolute value less than 2π (the radius of convergence of this power series). These definitions can be shown to be equivalent using mathematical induction. The initial condition is immediate from L'Hôpital's rule. To obtain the recurrence, multiply both sides of the equation by . Then, using the Taylor series for the exponential function, By expanding this as a Cauchy product and rearranging slightly, one obtains It is clear from this last equality that the coefficients in this power series satisfy the same recurrence as the Bernoulli numbers. Other forms and conventions One may also write where Bn + 1(m) is the (n + 1)th-degree Bernoulli polynomial. Bernoulli numbers may be calculated by using the following recursive formula: for m > 0, and B0 = 1. An alternative convention for the Bernoulli numbers is to set B1 = 1/2 rather than −1/2. If this convention is used, then all the Bernoulli numbers may be calculated by a different recursive formula without further qualification: Dividing both sides by m + 1 then gives a form suggestive of the connection with the Riemann zeta function if the j=0 case is understood as a limit to deal with the pole at ζ(1): The terms of this sum are the coefficients given by Faulhaber's formula for the closed form of and so this recursive definition is merely reflecting the fact that these sums evaluate to 1 when n=1 for any m. In the alternative convention, the generating function is Values of the Bernoulli numbers Bn = 0 for all odd n other than 1. B1 = 1/2 or −1/2 depending on the convention adopted (see below). The first few non-zero Bernoulli numbers (sequences and in OEIS) and some larger ones are listed below. n N D Bn = N / D 0 1 1 +1.00000000000 1 -1 2 -0.50000000000 2 1 6 +0.16666666667 4 -1 30 -0.03333333333 6 1 42 +0.02380952381 8 -1 30 -0.03333333333 10 5 66 +0.07575757576 12 -691 2730 -0.25311355311 14 7 6 +1.16666666667 16 -3617 510 -7.09215686275 18 43867 798 +54.9711779448 Efficient computation of Bernoulli numbers In some applications it is useful to be able to compute the Bernoulli numbers B0 through Bp − 3 modulo p, where p is a prime; for example to test whether Vandiver's conjecture holds for p, or even just to determine whether p is an irregular prime. It is not feasible to carry out such a computation using the above recursive formulae, since at least (a constant multiple of) p2 arithmetic operations would be required. Fortunately, faster methods have been developed which require only O(p (log p)2) operations (see big-O notation). David Harvey describes an algorithm for computing Bernoulli numbers by computing Bn modulo p for many small primes p, and then reconstructing Bn via the Chinese Remainder Theorem. Harvey writes that the asymptotic time complexity of this algorithm is O(n2 log(n)2+eps) and claims that this implementation is significantly faster than implementations based on other methods. Harvey's implementation is included in Sage since version 3.1. Using this implementation Harvey computed Bn for n = 108, which is a new record (October 2008). Prior to that Bernd Kellner computed Bn to full precision for n = 106 on December 2002 and Oleksandr Pavlyk for n = 107 with 'Mathematica' on April 2008. Computer Year n Digits J.

In 2009, a sixteen year-old Iraqi immigrant living in Sweden submitted a proof to Uppsala University, correctly simplifying the computation of Bernoulli numbers. Mathematicians claim this proof has been discovered before and is well known in the field.

The main formula can be seen in the second half of the facsimile given above. The constant coefficients denoted A, B, C and D by Bernoulli are mapped to the notation which is now prevalent as A = B2, B = B4, C = B6, D = B8. In the expression c·c−1·c−2·c−3 the small dots are used as grouping symbols, not as signs for multiplication. Using today's terminology these expressions are falling factorial powers . The factorial notation k! as a shortcut for 1×2×...×k was not introduced until 100 years later. The integral symbol on the left hand side goes back to Gottfried Wilhelm Leibniz in 1675 who used it as a long letter S for "summa" (sum). (The Mathematics Genealogy Project Mathematics Genealogy Project shows Leibniz as the doctoral adviser of Jakob Bernoulli. See also the Earliest Uses of Symbols of Calculus Earliest Uses of Symbols of Calculus .) The letter n on the left hand side is not an index of summation but gives the upper limit of the range of summation which is to be understood as 1,2,...,n. Putting things together, for positive c, today a mathematician is likely to write Bernoulli's formula as In fact this formula imperatively suggests to set B1 = 1/2 when switching from the so called 'archaic' enumeration which uses only the even indices 2,4,.. to the modern form (more on different conventions in the next paragraph). Most striking in this context is the fact that the falling factorial has for k = 0 the value 1/(c + 1). (See the explanation in Concrete Mathematics, (2.51) .) Thus Bernoulli's formula can and has to be written if B1 stands for the value Bernoulli himself has given to the coefficient at that position. Different viewpoints and conventions The Bernoulli numbers can be regarded from four main viewpoints: as standalone arithmetical objects, as combinatorial objects, as values of a sequence of certain polynomials, as values of the Riemann zeta function. Each of these viewpoints leads to a set of more or less different conventions. Bernoulli numbers as standalone arithmetical objects. Associated sequence: 1/6, −1/30, 1/42, −1/30,... This is the viewpoint of Jakob Bernoulli. (See the cutout from his Ars Conjectandi, first edition, 1713). The Bernoulli numbers are understood as numbers, recursive in nature, invented to solve a certain arithmetical problem, the summation of powers, which is the paradigmatic application of the Bernoulli numbers. It is misleading to call this viewpoint 'archaic'. For example Jean-Pierre Serre uses it in his highly acclaimed book A Course in Arithmetic which is a standard textbook used at many universities today. Bernoulli numbers as combinatorial objects. Associated sequence: 1, +1/2, 1/6, 0,.... This view focuses on the connection between Stirling numbers and Bernoulli numbers and arises naturally in the calculus of finite differences. In its most general and compact form this connection is summarized by the definition of the Stirling polynomials σn(x), formula (6.52) in Concrete Mathematics by Graham, Knuth and Patashnik. In consequence Bn = n! σn(1) for n ≥ 0. Bernoulli numbers as values of a sequence of certain polynomials. Assuming the Bernoulli polynomials as already introduced the Bernoulli numbers can be defined in two different ways: Bn = Bn(0). Associated sequence: 1, −1/2, 1/6, 0,.... Bn = Bn(1). Associated sequence: 1, +1/2, 1/6, 0,.... The two definitions differ only in the sign of B1. The choice Bn = Bn(0) is the convention used in the Handbook of Mathematical Functions. Bernoulli numbers as values of the Riemann zeta function. Associated sequence: 1, +1/2, 1/6, 0,.... The Bernoulli numbers as given by the Riemann zeta function. This convention agrees with the convention Bn = Bn(1) (for example J. Neukirch and M. Kaneko). The sign '+' for B1 matches the representation of the Bernoulli numbers by the Riemann zeta function. In fact the identity nζ(1−n) = (−1)n+1Bn valid for all n > 0 is then replaced by the simpler nζ(1−n) = -Bn. (See the paper of S. C. Woon.) (Note that in the foregoing equation for n = 0 and n = 1 the expression −nζ(1 − n) is to be understood as limx → n −xζ(1 − x).) Application of the Bernoulli number Arguably the most important application of the Bernoulli number in mathematics is their use in the Euler-MacLaurin formula. Assuming that f is a sufficiently often differentiable function the Euler-MacLaurin formula can be written as Concrete Mathematics, (9.67). This formulation assumes the convention B1 = -1/2. However, if one sets B1 = 1/2 then this formula can also be written as Here f(0) = f which is a commonly used notation identifying the zero-th derivative of f with f. Moreover, let f(-1) denote an antiderivative of f. By the fundamental theorem of calculus . Thus the last formula can be further simplified to the following succinct form of the Euler-Maclaurin formula This form is for example the source for the important Euler-MacLaurin expansion of the zeta function Here denotes the rising factorial power. Concrete Mathematics, (2.44) and (2.52) Combinatorial definitions The connection of the Bernoulli number to various kinds of combinatorial numbers is based on the classical theory of finite differences and on the combinatorial interpretation of the Bernoulli numbers as an instance of a fundamental combinatorial principle, the inclusion-exclusion principle. Connection with the Worpitzky number The definition to proceed with was developed by Julius Worpitzky in 1883. Besides elementary arithmetic only the factorial function n! and the power function km is employed. The signless Worpitzky numbers are defined as They can also be expressed through the Stirling set number A Bernoulli number is then introduced as an inclusion-exclusion sum of Worpitzky numbers weighted by the sequence 1, 1/2, 1/3,... This representation has B1 = 1/2. Worpitzky's representation of the Bernoulli number B0 = 1/1 B1 = 1/1 − 1/2 B2 = 1/1 − 3/2 + 2/3 B3 = 1/1 − 7/2 + 12/3 − 6/4 B4 = 1/1 − 15/2 + 50/3 − 60/4 + 24/5 B5 = 1/1 − 31/2 + 180/3 − 390/4 + 360/5 − 120/6 B6 = 1/1 − 63/2 + 602/3 − 2100/4 + 3360/5 − 2520/6 + 720/7 Connection with the Stirling set number A similar combinatorial representation derives from Here the Bernoulli numbers are an inclusion-exclusion over the set of length-n words, where the sum is taken over all words of length n with k distinct letters, and normalized by k + 1. The combinatorics of this representation can be seen from: Connection with the Stirling cycle number Let denote the signless Stirling cycle number. The two main formulas relating these number to the Bernoulli number (B1 = 1/2) are and the inversion of this sum (for n ≥ 0, m ≥ 0) Here the number An,m are the rational Akiyama-Tanigawa number, the first few of which are displayed in the following table. Akiyama-Tanigawa number n \ m 0 1 2 3 40 11/21/31/41/51 1/21/31/41/5...2 1/61/63/20......3 01/30.........4 -1/30............ These relations lead to a simple algorithm to compute the Bernoulli number. The input is the first row, A0,m = 1/(m + 1) and the output are the Bernoulli number in the first column An,0 = Bn . This transformation is shown in pseudo-code below. Akiyama-Tanigawa algorithm for Bn Enter integer n. For m from 0 by 1 to n do A[m] ← 1/(m + 1) For j from m by −1 to 1 do A[j − 1] ← j × (A[j − 1] − A[j]) Return A[0] (which is Bn).</center> Connection with the Eulerian number The Eulerian number are the number of permutations of {1,2,...,n} with m ascents. They were introduced by Leonhard Euler in 1755 and in the notation of D. E. Knuth Concrete Mathematics, Table 254 Euler's triangle. written as The two main formulas connecting the Eulerian number to the Bernoulli number are: Both formulas are valid for n ≥ 0 if B1 is set to 1/2. If B1 is set to −1/2 they are valid only for n ≥ 1 and n ≥ 2 respectively. Asymptotic approximation Leonhard Euler expressed the Bernoulli numbers in terms of the Riemann zeta function as It then follows from the Stirling formula that, as n goes to infinity, Integral representation and continuation The integral has as special values b(2n) = B2n for n > 0. The integral might be considered as a continuation of the Bernoulli numbers to the complex plane and this was indeed suggested by Peter Luschny in 2004. For example b(3) = (3/2)ζ(3)Π−3Ι and b(5) = −(15/2) ζ(5) Π −5Ι. Here ζ(n) denotes the Riemann zeta function and Ι the imaginary unit. It is remarkable that already Leonhard Euler (Opera Omnia, Ser. 1, Vol. 10, p. 351) considered these numbers and calculated Euler's values are unsigned and real, but obviously his aim was to find a meaningful way to define the Bernoulli numbers at the odd integers n > 1. The relation to the Euler numbers and π The Euler numbers are a sequence of integers intimately connected with the Bernoulli numbers. Comparing the asymptotic expansions of the Bernoulli and the Euler numbers shows that the Euler numbers E2n are in magnitude approximately (2/π)(42n − 22n) times larger than the Bernoulli numbers B2n. In consequence: This asymptotic equation reveals that π lies in the common root of both the Bernoulli and the Euler numbers. In fact π could be computed from these rational approximations. Bernoulli numbers can be expressed through the Euler numbers and vice versa. Since for n odd Bn = En = 0 (with the exception B1), it suffices to regard the case when n is even. These conversion formulas express an inverse relation between the Bernoulli and the Euler numbers. But more important, there is a deep arithmetic root common to both kinds of numbers, which can be expressed through a more fundamental sequence of numbers, also closely tied to π. These numbers are defined for n > 1 as and S1 = 1 by convention. The magic of these numbers lies in the fact that they turn out to be rational numbers. This was first proved by Leonhard Euler 1734 in a landmark paper `De summis serierum reciprocarum' (On the sums of series of reciprocals) and fascinated mathematicians ever since. The first few of these numbers are The Bernoulli numbers and Euler numbers are best understood as special views of these numbers, selected from the sequence Sn and scaled for use in special applications. The expression [n even] has the value 1 if n is even and 0 otherwise (Iverson bracket). These identities show that the quotient of Bernoulli and Euler numbers at the beginning of this section is just the special case of Rn = 2 Sn / Sn+1 when n is even. The Rn are rational approximations to π and two successive terms always enclose the true value of π. Beginning with n = 1 the sequence starts These rational numbers also appear in the last paragraph of Euler's paper cited above. But it was only in September 2007 that this classical sequence found its way into the Encyclopedia of Integer Sequences (A132049). An algorithmic view: the Seidel triangle The sequence Sn has another unexpected yet important property: The denominators of Sn divide the factorial (n − 1)!. In other words: the numbers Tn = Sn(n − 1)! are integers. Thus the above representations of the Bernoulli and Euler numbers can be rewritten in terms of this sequence as These identities make it easy to compute the Bernoulli and Euler numbers: the Euler numbers En are given immediately by T2n + 1 and the Bernoulli numbers B2n are obtained from T2n by some easy shifting, avoiding rational arithmetic. What remains is to find a convenient way to compute the numbers Tn. However, already in 1877 Philipp Ludwig von Seidel published an ingenious algorithm which makes it extremely simple to calculate Tn. Seidel's algorithm for TnImage:SeidelAlgorithmForTn.png [begin] Start by putting 1 in row 0 and let k denote the number of the row currently being filled. If k is odd, then put the number on the left end of the row k − 1 in the first position of the row k, and fill the row from the left to the right, with every entry being the sum of the number to the left and the number to the upper. At the end of the row duplicate the last number. If k is even, proceed similar in the other direction. [end] Seidel's algorithm is in fact much more general (see the exposition of Dominique Dumont (1981)) and was rediscovered several times thereafter. Similar to Seidel's approach D. E. Knuth and T. J. Buckholtz (1967) gave a recurrence equation for the numbers T2n and recommended this method for computing B2n and E2n ‘on electronic computers using only simple operations on integers’. V. I. Arnold rediscovered Seidel's algorithm in 1991 and later Millar, Sloane and Young popularized Seidel's algorithm under the name boustrophedon transform. A combinatorial view: alternating permutations Around 1880, three years after the publication of Seidel's algorithm, Désiré André proved a now classic result of combinatorial analysis. Looking at the first terms of the Taylor expansion of the trigonometric functions tan x and sec x André made a startling discovery. The coefficients are the Euler numbers of odd and even index, respectively. In consequence the ordinary expansion of tan x + sec x has as coefficients the rational numbers Sn. André then succeeded by means of a recurrence argument to show that the alternating permutations of odd size are enumerated by the Euler numbers of odd index (also called tangent numbers) and the alternating permutations of even size by the Euler numbers of even index (also called secant numbers). Generalizations by polynomials The Bernoulli polynomials can be regarded as generalizations of the Bernoulli numbers the same as the Euler polynomials are generalizations of the Euler numbers. Arithmetical properties of the Bernoulli numbers The Bernoulli numbers can be expressed in terms of the Riemann zeta function as Bn = − nζ(1 − n) for integers n ≥ 0 provided for n = 0 and n = 1 the expression − nζ(1 − n) is understood as the limiting value and the convention B1 = 1/2 is used. This intimately relates them to the values of the zeta function at negative integers. As such, they could be expected to have and do have deep arithmetical properties, a fact discovered by Kummer in his work on Fermat's last theorem. Divisibility properties of the Bernoulli numbers are related to the ideal class groups of cyclotomic fields by a theorem of Kummer and its strengthening in the Herbrand-Ribet theorem, and to class numbers of real quadratic fields by Ankeny-Artin-Chowla. We also have a relationship to algebraic K-theory; if cn is the numerator of Bn/2n, then the order of is −c2n if n is even, and 2c2n if n is odd. The Agoh-Giuga conjecture postulates that p is a prime number if and only if pBp−1 is congruent to −1 mod p. Von Staudt–Clausen theorem The von Staudt–Clausen theorem was given by Karl Georg Christian von Staudt and Thomas Clausen independently in 1840. It describes the arithmetical structure of the Bernoulli numbers. The von Staudt–Clausen theorem has two parts. The first one describes how the denominators of the Bernoulli numbers can be computed. Paraphrasing the words of Clausen it can be stated as: “The denominator of the 2nth Bernoulli number can be found as follows: Add to all divisors of 2n, 1, 2, a, a', ..., 2n the unity, which gives the sequence 2, 3, a + 1, a' + 1, ..., 2n + 1. Select from this sequence only the prime numbers 2, 3, p, p', etc. and build their product.” Clausen's algorithm translates almost verbatim to a modern computer algebra program, which looks similar to the pseudocode on the left hand site of the following table. On the right hand side the computation is traced for the input n = 88. It shows that the denominator of B88 is 61410. Clausen's algorithm for the denominator of Bn Clausen: function(integer n) | n = 88 S = divisors(n); | {1, 2, 4, 8, 11, 22, 44, 88} S = map(k → k + 1, S); | {2, 3, 5, 9, 12, 23, 45, 89} S = select(isprime, S); | {2, 3, 5, 23, 89} return product(S); | 61410 The second part of the von Staudt–Clausen theorem is a very remarkable representation of the Bernoulli numbers. This representation is given for the first few nonzero Bernoulli numbers in the next table. Von Staudt–Clausen representation of Bn B0 = 1 B1 = 1 − 1/2 B2 = 1 − 1/2 − 1/3 B4 = 1 − 1/2 − 1/3 − 1/5 B6 = 1 − 1/2 − 1/3 − 1/7 B8 = 1 − 1/2 − 1/3 − 1/5 B10 = 1 − 1/2 − 1/3 − 1/11 The theorem affirms the existence of an integer In such that The sum is over the primes p for which p − 1 divides n. These are the same primes which are employed in the Clausen algorithm. The proposition holds true for all n ≥ 0, not only for even n. I1 = 2 and for odd n > 1, In = 1. Consequences of the von Staudt–Clausen theorem are: the denominators of the Bernoulli numbers are square-free and for n ≥ 2 divisible by 6. Why do the odd Bernoulli numbers vanish? The sum can be evaluated for negative values of the index n. Doing so will show that it is an odd function for even values of k, which implies that the sum has only terms of odd index. This and the formula for the Bernoulli sum imply that B2k+1−m is 0 for m odd and greater than 1; and that the term for B1 is cancelled by the subtraction. The von Staudt-Clausen theorem combined with Worpitzky's representation also gives a combinatorial answer to this question (valid for n > 1). From the von Staudt-Clausen theorem it is known that for odd n > 1 the number 2Bn is an integer. This seems trivial if one knows beforehand that in this case Bn = 0. However, by applying Worpitzky's representation one gets as a sum of integers, which is not trivial. Here a combinatorial fact comes to surface which explains the vanishing of the Bernoulli numbers at odd index. Let Sn,m be the number of surjective maps from {1, 2, ..., n} to {1, 2, ..., m}, then . The last equation can only hold if This equation can be proved by induction. The first two examples of this equation are n = 4 : 2 + 8 = 7 + 3, n = 6: 2 + 120 + 144 = 31 + 195 + 40. Thus the Bernoulli numbers vanish at odd index because some non-obvious combinatorial identities are embodied in the Bernoulli numbers. p-adic continuity An especially important congruence property of the Bernoulli numbers can be characterized as a p-adic continuity property. If b, m and n are positive integers such that m and n are not divisible by p − 1 and , then Since , this can also be written where u = 1 − m and v = 1 − n, so that u and v are nonpositive and not congruent to 1 mod p − 1. This tells us that the Riemann zeta function, with 1 − p−s taken out of the Euler product formula, is continuous in the p-adic numbers on odd negative integers congruent mod p − 1 to a particular , and so can be extended to a continuous function for all p-adic integers the p-adic Zeta function. Bernoulli numbers and the Riemann hypothesis The connection between the Bernoulli numbers and the Riemann zeta function is strong enough to provide an alternate formulation of the Riemann hypothesis (RH) which uses only the Bernoulli number. In fact in 1916 M. Riesz proved that the RH is equivalent to the following assertion: For every ε > 1/4 there exists a constant Cε > 0 (depending on ε) such that |R(x)| < Cε xε as x → ∞. Here R(x) is the Riesz function denotes the rising factorial power in the notation of D. E. Knuth. The number βn = Bn/n occur frequently in the study of the zeta function and are significant because βn is a p-integer for primes p where p − 1 does not divide n. The βn are called divided Bernoulli number. Ramanujan's congruences The following relations, due to Ramanujan, provide a more efficient method for calculating Bernoulli numbers: Use of Bernoulli numbers in topology The Kervaire-Milnor formula for the order of the cyclic group of diffeomorphism classes of exotic (4n − 1)-spheres which bound parallelizable manifolds for involves Bernoulli numbers; if B(n) is the numerator of B4n/n, then is the number of such exotic spheres. (The formula in the topological literature differs because topologists use a different convention for naming Bernoulli numbers; this article uses the number theorists' convention.) Assorted identities <ul> Let n be non-negative and even The nth cumulant of the uniform probability distribution on the interval [−1, 0] is Bn/n. <li> Let n¡ = 1/n! and n ≥ 1. Then Bn is n! times the determinant of the following matrix. <table> <tr> Bn = 1 ───n¡ <td> <table style="text-align: center; border-left: 2px solid #000000; border-right: 2px solid #000000" cellspacing="4" cellpadding="4"> 2¡ 1¡ 0 0 0 ... 0 3¡ 2¡ 1¡ 0 0 ... 0 4¡ 3¡ 2¡ 1¡ 0 ... 0 ... ... ... ... ... ... ...

Let n ≥ 1. Then Let n ≥ 1 and m ≥ 1. Then Let n ≥ 4 and the harmonic number. Then Let n ≥ 4. Yuri Matiyasevich found (1997) Let n ≥ 1 This is an identity by Faber-Pandharipande-Zagier-Gessel. Choose x = 0 or x = 1 to get a Bernoulli number identity according to your favourite convention. The next formula is true for n ≥ 0 if B1 = B1(1) = 1/2, but only for n ≥ 1 if B1 = B1(0) = -1/2. Let n ≥ 0 and [b] = 1 if b is true, 0 otherwise. and </ul> See also poly-Bernoulli number q-Bernoulli number Bernoulli polynomials Riemann zeta function Hurwitz zeta function Euler number Euler summation References . . . . . . {{citation|last1=Buhler|first1=J.|last2=Crandall|first2=R.|last3=Ernvall|first3=R.|last4=Metsankyla|first4=T.|last5=Shokrollahi|first5=M.|title=Irregular Primes and Cyclotomic Invariants to 12 Million|journal=Journal of Symbolic Computation|volume=31|issue=1–2|year=2001|pages=89–96|doi=10.1006/jsco.1999.1011}}. . . . . . . ; On the sums of series of reciprocals, arXiv:math/0506415v2 (math.HO). arXiv:math/0702300v2 (math.NT) . arXiv:0807.1347v2 math.NT . . . .

Physical geography Central America and the Caribbean Plate. Physiographically, Central America is the tapering isthmus of southern North America, and the mainland of Middle America in turn, extending from the Isthmus of Tehuantepec in southern Mexico southeastward to the Isthmus of Panama where it connects to the Colombian Pacific Lowlands in northwestern South America. Alternatively, the Trans-Mexican Volcanic Belt delimits the region on the north. Central America has an area of some 592,000 square kilometres. The Pacific Ocean lies to the southwest, the Caribbean Sea lies to the northeast, and the Gulf of Mexico lies to the north. Most of Central America rests atop the Caribbean Plate. The region is geologically active, with volcanic eruptions and earthquakes occurring from time to time. Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, and three earthquakes devastated El Salvador, one in 1986 and two in 2001. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in the agriculturally productive highland areas. Human geography Geopolitically, Central America has traditionally consisted of the following countries: Name of territory,with flag Area(km²) Areas and population estimates taken from the 2008 CIA World Factbook, whose population estimates are as of July 2007. Population(July 2007 est.) Population density(per km²) Capital Officiallanguage Belmopan English San José Spanish San Salvador Spanish Guatemala City Spanish Tegucigalpa Spanish Managua Spanish Panama City Spanish Total Many modern definitions of Central America include Belize, and Panama, which did not exist upon the formation of the Federal Republic of Central America, a short-lived union created after most of the region gained independence from Spain in the 19th century. The territory now occupied by Belize was originally contested by the United Kingdom and the Spanish Empire and, later, Guatemala (which has considered it, wholly or partially, an eastern department); it became a British colony (British Honduras) in 1871 and gained independence in 1981. Panama, situated on the Isthmus of Panama, is sometimes regarded as a transcontinental territory. Because of the Panama Canal, it is considered part of both North America and South America. For much of its post-Columbian history, Panama has been connected to South America. Panama was a possession of the Viceroyalty of New Granada, and then, following independence, became a part of la Gran Colombia (Greater Colombia). Only after independence from Colombia in 1903 did some begin to regard Panama as a North or Central American entity. History Political Evolution of Central America and the Caribbean from 1700 to present In pre-Columbian times, the north-western areas of modern Central America were part of the Mesoamerican civilization. The Native American societies of Mesoamerica occupied the land ranging from central Mexico in the north to Costa Rica in the south. Most notable among these were the Maya, who had built numerous cities throughout the region, and the Aztecs, who created a vast empire. The pre-Columbian cultures of Panama traded with both Mesoamerica and South America, and can be considered transitional between those two cultural areas. Map of the Republic of Central America Following Christopher Columbus's discovery of the Americas for Spain, the Spanish sent numerous expeditions to the region, and they began their conquest of Maya lands in the 1520s. In 1540, Spain established the Captaincy General of Guatemala, which extended from southern Mexico to Costa Rica, and thus encompassed most of what is currently known as Central America, with the exception of British Honduras (present-day Belize). This lasted nearly three centuries, until a rebellion (which followed closely on the heels of the Mexican War of Independence) in 1821. After the dissolution of Spanish authority, the former Captaincy General remained intact as part of the short-lived First Mexican Empire, then turned into the Federal Republic of Central America, which was a representative democracy with its capital at Guatemala City. This union consisted of the present day nations of Guatemala (which included the former state of Los Altos), Honduras, El Salvador, Nicaragua, Costa Rica (which included a region which is now part of Panama, and the Guanacaste Province which was once part of Nicaragua), and Soconusco, a portion of the modern Mexican state of Chiapas. The Republic lasted from 1823 to 1838, when it began to disintegrate due to civil wars. Central American integration Sistema de Integración Centroamericana Central American Integration System Motto: «Peace, Development, Liberty and Democracy» Anthem: La Granadera Area 560,988 km² Population 41,753,000 hab. Countries Countries part of the SICA Central America is going through a process of political, economic and cultural transformation that started in 1907 with the creation of the Central American Court of Justice. In 1951 the integration process continued with the signature of the San Salvador Treaty that created the ODECA, the Organization of Central American States. Unfortunately, the ODECA was not completely successful due to internal conflicts between several states of the region. It was until 1991 that the integration agenda was completed with the creation of the SICA, Sistema para la Integración Centroamericana or System for the Central American Integration. The SICA provided a clear legal base to avoid discrepancies between the member states. The SICA membership includes the 7 nations of Central America plus the Dominican Republic, a state that is part of the Caribbean. On December 6, 2008 SICA announced an agreement to pursue a common currency and common passport for the member nations. No timeline for implementation was discussed. Central America already has several supranational institutions such as the Central American Parliament, the Central American Bank for Economic Integration and the Central American Common Market. Foreign relations Until recently, all Central American countries have maintained diplomatic relations with the Republic of China (Taiwan) instead of the People's Republic of China. Ministry of Foreign Affairs, Republic of China President Oscar Arias of Costa Rica, however, established diplomatic relations with the People's Republic of China in 2007, severing formal diplomatic ties with the Republic of China (Taiwan). Usage "Central America" may mean different things to different people in the world according to the context: In English, Central America is considered a region of the North American continent. "Central America." Merriam-Webster's Collegiate Dictionary. Geopolitically, it usually comprises seven countries – Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama.

Fowler's Modern English Usage (ISBN 0-19-861021-1) New York: Oxford University Press, p. 48. Some geographers include the five states of Campeche, Chiapas, Tabasco, Quintana Roo, and Yucatán, together representing 12.1% of the country's total area. In Latin America, Iberia, and some other parts of Europe, the Americas are considered to be a single continent, and Central America is considered a region of this continent. In Ibero-America, the region is defined as seven nations – Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama – and may occasionally include Mexico's southernmost region. Centroamérica (Mexican version)"/Centroamérica (Spaniard version). Encarta Online Encyclopedia. Geopolitically, Mexico is considered part of North America. Norteamérica Occasionally, the term Central America is used synonymously with Middle America. Among some German geographers, Mittelamerika may be used to refer to the territories on the Central American isthmus. The UN geoscheme defines the region as all states of mainland North America south of the United States; conversely, the European Union excludes Belize and Mexico from its definition of the region.

In linear algebra, a basis is a set of vectors that, in a linear combination, can represent every vector in a given vector space or free module, and such that no element of the set can be represented as a linear combination of the others. In other words, a basis is a linearly independent spanning set. Definition This picture illustrates the standard basis in R2. The red and blue vectors are the elements of the basis; the green vector can be given in terms of the basis vectors. A basis B of a vector space V is a linearly independent subset of V that spans (or generates) V. In more detail, suppose that B = { v1, …, vn } is a finite subset of a vector space V over a field F (such as the real or complex numbers R or C). Then B is a basis if it satisfies the following conditions: the linear independence property, for all a1, …, an ∈ F, if a1v1 + … + anvn = 0, then necessarily a1 = … = an = 0; and the spanning property, for every x in V it is possible to choose a1, …, an ∈ F such that x = a1v1 + … + anvn. The numbers ai are called the coordinates of the vector x with respect to the basis B, and by the first property they are uniquely determined. A vector space that has a finite basis is called finite-dimensional. To deal with infinite-dimensional spaces, we must generalize the above definition to include infinite basis sets. We therefore say that a set (finite or infinite) B ⊂ V is a basis, if every finite subset B0 ⊆ B obeys the independence property shown above; and for every x in V it is possible to choose a1, …, an ∈ F and v1, …, vn ∈ B such that x = a1v1 + … + anvn. The sums in the above definition are all finite because without additional structure the axioms of a vector space do not permit us to meaningfully speak about an infinite sum of vectors. Settings that permit infinite linear combinations allow alternative definitions of the basis concept: see Related notions below. It is often convenient to list the basis vectors in a specific order, for example, when considering the transformation matrix of a linear map with respect to a basis. We then speak of an ordered basis, which we define to be a sequence (rather than a set) of linearly independent vectors that span V: see Ordered bases and coordinates below. Properties Again, B denotes a subset of a vector space V. Then, B is a basis if and only if any of the following equivalent conditions are met: B is a minimal generating set of V, i.e., it is a generating set but no proper subset of B is. B is a maximal set of linearly independent vectors, i.e., it is a linearly independent set but no other linearly independent set contains it as a proper subset. Every vector in V can be expressed as a linear combination of vectors in B in a unique way. If the basis is ordered (see Ordered bases and coordinates below) then the coefficients in this linear combination provide coordinates of the vector relative to the basis. Every vector space has a basis. The proof of this requires the axiom of choice. All bases of a vector space have the same cardinality (number of elements), called the dimension of the vector space. This result is known as the dimension theorem, and requires the ultrafilter lemma, a strictly weaker form of the axiom of choice. Also many vector sets can be attributed a standard basis which comprises both spanning and linearly independent vectors. Standard bases for example: In Rn {E1,...,En} where En is the n-th column of the identity matrix which consists of all ones in the main diagonal and zeros everywhere else. This is because the columns of the identity matrix are linerly independent can always span a vector set by expressing it as a linear combination. In P2 where P2 is the set of all polynomials of degree at most 2 {1,x,x2} is the standard basis. In M22 {M1,1,M1,2,M2,1,M2,2} where M22 is the set of all 2x2 matrices. and Mm,n is the 2x2 matrix with a 1 in the m,n position and zeros everywhere else. This again is a standard basis since it is linearly independent and spanning. Examples Consider R2, the vector space of all coordinates (a, b) where both a and b are real numbers. Then a very natural and simple basis is simply the vectors e1 = (1,0) and e2 = (0,1): suppose that v = (a, b) is a vector in R2, then v = a (1,0) + b (0,1). But any two linearly independent vectors, like (1,1) and (−1,2), will also form a basis of R2 (see the section Proving that a finite spanning set is a basis further down). More generally, the vectors e1, e2, ..., en are linearly independent and generate Rn. Therefore, they form a basis for Rn and the dimension of Rn is n. This basis is called the standard basis. Let V be the real vector space generated by the functions et and e2t. These two functions are linearly independent, so they form a basis for V. Let R[x] denote the vector space of real polynomials; then (1, x, x2, ...) is a basis of R[x]. The dimension of R[x] is therefore equal to aleph-0. Basis extension Between any linearly independent set and any generating set there is a basis. More formally: if L is a linearly independent set in the vector space V and G is a generating set of V containing L, then there exists a basis of V that contains L and is contained in G. In particular (taking G = V), any linearly independent set L can be "extended" to form a basis of V. These extensions are not unique. Proving that a finite spanning set is a basis To prove that a finite spanning set B is a basis for a finite-dimensional vector space V, it is sufficient to show that the number of elements in B equals the dimension of V, and one of the following: B is linearly independent, or span(B) = V. This does not work for infinite-dimensional vector spaces. Example of alternative proofs Often, a mathematical result can be proven in more than one way. Here, using three different proofs, we show that the vectors (1,1) and (-1,2) form a basis for R2. From the definition of basis We have to prove that these two vectors are linearly independent and that they generate R2. Part I: To prove that they are linearly independent, suppose that there are numbers a,b such that: Then: and and Subtracting the first equation from the second, we obtain: so And from the first equation then: Part II: To prove that these two vectors generate R2, we have to let (a,b) be an arbitrary element of R2, and show that there exist numbers x,y such that: Then we have to solve the equations: Subtracting the first equation from the second, we get: and then and finally By the dimension theorem Since (-1,2) is clearly not a multiple of (1,1) and since (1,1) is not the zero vector, these two vectors are linearly independent. Since the dimension of R2 is 2, the two vectors already form a basis of R2 without needing any extension. By the invertible matrix theorem Simply compute the determinant Since the above matrix has a nonzero determinant, its columns form a basis of R2. See: invertible matrix. Ordered bases and coordinates A basis is just a set of vectors with no given ordering. For many purposes it is convenient to work with an ordered basis. For example, when working with a coordinate representation of a vector it is customary to speak of the "first" or "second" coordinate, which makes sense only if an ordering is specified for the basis. For finite-dimensional vector spaces one typically indexes a basis {vi} by the first n integers. An ordered basis is also called a frame. Suppose V is an n-dimensional vector space over a field F. A choice of an ordered basis for V is equivalent to a choice of a linear isomorphism φ from the coordinate space Fn to V.Proof. The proof makes use of the fact that the standard basis of Fn is an ordered basis. Suppose first thatφ : Fn → Vis a linear isomorphism. Define an ordered basis {vi} for V by vi = φ(ei) for 1 ≤ i ≤ nwhere {ei} is the standard basis for Fn. Conversely, given an ordered basis, consider the map defined by φ(x) = x1v1 + x2v2 + ... + xnvn, where x = x1e1 + x2e2 + ... + xnen is an element of Fn. It is not hard to check that φ is a linear isomorphism. These two constructions are clearly inverse to each other. Thus ordered bases for V are in 1-1 correspondence with linear isomorphisms Fn → V. The inverse of the linear isomorphism φ determined by an ordered basis {vi} equips V with coordinates: if, for a vector v ∈ V, φ-1(v) = (a1, a2,...,an) ∈ Fn, then the components aj = aj(v) are the coordinates of v in the sense that v = a1(v) v1 + a2(v) v2 + ... + an(v) vn. The maps sending a vector v to the components aj(v) are linear maps from V to F, because of φ-1 is linear. Hence they are linear functionals. They form a basis for the dual space of V, called the dual basis. Related notions In the context of infinite dimensional vector spaces over real or complex numbers, the notion Hamel basis (named after Georg Hamel) or algebraic basis is used to refer to a basis as defined in this article. This is because there exist different notions of bases better suited to the infinite dimensional setting. The most important alternatives are orthogonal bases on Hilbert spaces, Schauder bases and Markushevich bases on normed linear spaces. The common feature of the other notions is that they permit for taking infinite linear combinations of the basic vectors in order to generate the space. This, of course, requires that infinite sums are meaningfully defined on these spaces, as is the case for topological vector spaces - a large class of vector spaces including e.g. Hilbert spaces, Banach spaces or Fréchet spaces. The preference of other types of bases for infinite dimensional spaces is justified by the fact that the Hamel basis becomes "too big" in Banach spaces: If X is an infinite dimensional normed vector space which is complete (i.e. X is a Banach space), then any Hamel basis of X is necessarily uncountable. This is an easy consequence of Baire category theorem. The completeness as well as infinite dimension are crucial assumptions in the previous claim. Indeed, finite dimensional spaces have by definition finite basis and there are infinite dimensional (non-complete) normed spaces which have countable Hamel basis. Consider , the space of the sequences of real numbers which have only finitely many non-zero coordinates, with the norm The standard basis is its countable Hamel basis. Example In the study of Fourier series, one learns that the functions {1} ∪ { sin(nx), cos(nx) : n = 1, 2, 3, ... } are an "orthogonal basis" of the (real or complex) vector space of all (real or complex valued) functions on the interval [0, 2π] that are square-integrable on this interval, i.e., functions f satisfying The functions {1} ∪ { sin(nx), cos(nx) : n = 1, 2, 3, ... } are linearly independent, and every function f that is square-integrable on [0, 2π] is an "infinite linear combination" of them, in the sense that for suitable (real or complex) coefficients ak, bk. But most square-integrable functions cannot be represented as finite linear combinations of these basis functions, which therefore do not'' comprise a Hamel basis. Every Hamel basis of this space is much bigger than this merely countably infinite set of functions. Hamel bases of spaces of this kind are of little (if any) interest, whereas orthonormal bases of these spaces are essential in Fourier analysis.

7,779 | Transport_in_Belgium | This article is about transportation in Belgium. Railways Main article: Rail transport in Belgium There is a total of 3,536 kilometres, (2,563 km double track (1998)), of which 2,950 km are electrified, mainly at 3,000 volts DC but with 351 km at 25 kV 50 Hz AC (2004) and all on standard gauge of 1.435 m. In 2004 the NMBS/SNCB, the National Railway Company of Belgium, carried 178.4 million passengers a total of 8,676 million passenger-kilometres. Due to the high population density, operations are relatively profitable, so tickets are cheap and the frequency of services is high. The NMBS/SNCB is permanently updating its rolling stock. The network currently includes two high speed lines suitable for 300 km/h traffic: HSL 1 runs from just south of Brussels to the French border, where it continues to Paris and Lille (and London beyond that). HSL 2 runs from Leuven to Liège, and HSL 3 will continue this route from Liège to the German border near Aachen. HSL 4 runs from Antwerpen to Rotterdam (in the Netherlands). HSL 3 and 4 were originally scheduled for completion in 2007 and although the track is laid the rolling stock is delayed. Both lines are equipped with ERTMS (ETCS level 2 + GSM-R, access and fall-back in level 1). Electrification is at 3 kV DC, with the exception of the new high-speed lines, and of two recently electrified lines in the south of the country which are at 25 kV AC. Trains, contrary to tram and road traffic, run on the left. Rail links with adjacent countries All adjacent countries use the same gauge. Netherlands - different voltage 3 kV DC/1500 V DC. The change of voltage occurs at the border; 3 kV Belgian trains can proceed under reduced power to the first station past the border (Roosendaal or Maastricht). Border crossings are at: Essen, Visé (Wezet) Meer (high speed line) Hamont, Lanaken and Zelzate (freight only) Eisden (planned, opening scheduled between 2012 and 2017) Achel (closed, reopening scheduled between 2012 and 2017) Sint-Gillis-Waas (closed), Turnhout (closed) Germany - different voltage 3 kV DC/15 kV AC. The change of voltage occurs in Aachen station where there is a switchable track so that 3kV monovoltage trains can reach Aachen. Border crossings are at: Welkenraedt Kelmis-Hergenrath (includes high speed traffic on the upgraded line) Losheimergraben, Raeren, Gemmenich (freight only). Steinebrück (closed), Luxembourg - different voltage 3 kV DC/25 kV AC. The change of voltage occurs in Luxembourg station; the section from the border to Luxembourg is at 3 kV DC. Border crossings are at: Arlon-Sterpenich, Gouvy Lengeler, Benonchamps, Lommersweiler (closed) France - different voltage 3 kV DC/25 kV AC. The change of voltage occurs at the border, except for the high-speed line which is 25 kV throughout. Border crossings are at: Mouscron (Moeskroen), Tournai-Blandain, Quiévrain, Aulnois, Erquelinnes, Athus, Froyennes high speed line at Esplechain De Panne and Momignies only irregular freight traffic Heer-Agimont (only touristic trains) Menen, Comines-Warneton, Leupegem, Antoing, Tournai, Péruwelz, Dour, Doische (closed) Metros and Light Rail In Belgium an extensive system of tram-like local railways called vicinal or buurtspoor lines crossed the country in the first half of the 20th century, and had a greater route length than the main-line railway system. The only survivors of the vicinal/buurtspoor system are the Kusttram and some sections of the Charleroi metro. Urban tram networks exist in Antwerp, Ghent and Brussels, and are gradually being extended. Metro systems in cities: Brussels, operated by MIVB/STIB. Tram/light rail systems in cities: Brussels, operated by MIVB/STIB, Antwerp, operated by De Lijn, Charleroi, operated by TEC, Ghent, operated by De Lijn. Other lines: Kusttram, covering almost the entire coast from France to the Netherlands - the longest tram line in the world. Operated by De Lijn. Some heavy metro infrastructures were built in Brussels, Antwerp and the Charleroi area, but these are currently used by light rail vehicles, and their conversion to full metro is not envisaged at present due to lack of funds. Roads total: 149,018 km (2002) highways: 1,729 km regional roads: 12,610 km others: 134,679 km Highways The highways in Belgium are marked with a letter A and a number. Most often however the European numbering system for the international E-road network is used. There is however not always a one-on-one relationship between the two numbering systems along the whole length of the highways.

The names start with a R then a first digit indicating the (old) province, and sometimes a second digit to further differentiate in between different ringways. Some major examples are: R0 is the outer ringway around Brussels. The R20 and R22 are (parts of) inner ringways around Brussels. R1 is the southern half ringway and R2 is the northern half ringway around Antwerp. R3 is the outer ringway and R9 is the inner ringway around Charleroi. The inner ring is counterclockwise-only. R4 is the outer ringway and R40 is the inner ringway around Ghent. R6 is the outer ringway and R12 is the inner ringway around Mechelen. R8 is the outer ringway and R36 is the inner ringway around Kortrijk. R23 is the ringway around Leuven. R30 is the inner ringway around Bruges. National roads The national roads are marked with a letter N and a number. The principal national roads fan out from Brussels, numbered in clockwise order: N1: Brussels - Mechelen - Antwerp N2: Brussels - Leuven - Diest - Hasselt - Maastricht N3: Brussels - Leuven - Tienen - Sint-Truiden - Liège - Aachen N4: Brussels - Wavre - Namur - Marche-en-Famenne - Bastogne - Arlon N5: Brussels - Charleroi - Philippeville N6: Brussels - Halle - Soignies - Mons N7: Halle - Ath - Tournai N8: Brussels - Ninove - Oudenaarde - Kortrijk - Ypres - Veurne - Koksijde N9: Brussels - Aalst - Ghent - Eeklo - Bruges - Ostend Secondary national roads intersect these.

7,780 | Persistence_of_vision | In the lilac chaser illusion, the omitted space is filled with a green circle due to persistence of vision. Persistence of vision is the phenomenon of the eye by which even nanoseconds of exposure to an image result in milliseconds of reaction (sight) from the retina to the optic nerves. This is because persistence of vision depends on chemical transmission of nerve responses, and this biochemical hysteresis is much slower than the light transmission. The myth of persistence of vision refers to the mistaken belief that human perception of motion (brain centered) is the result of persistence of vision (eye centered). The myth was debunked in 1912 by Wertheimer Wertheimer, 1912. Experimentelle Studien über das Sehen von Bewegung. Zeitschrift für Psychologie 61, pp. 161–265 but persists in many citations in modern texts. Motion perception has been shown to be the result of the Beta Phenomenon. A visual form of memory known as iconic memory has been described as the cause of this phenomenon Coltheart M. "The persistences of vision." Philos Trans R Soc Lond B Biol Sci. 1980 Jul 8;290(1038):57-69. PMID 6106242. . Although psychologists and physiologists have rejected the relevance of this theory to film viewership, film academics and theorists generally have not. Some scientists nowadays consider the entire theory a myth. Persistence of vision should be compared with the related phenomena of beta movement and phi movement. A critical part of understanding these visual perception phenomena is that the eye is not a camera: there is no "frame rate" or "scan rate" in the eye; instead, the eye/brain system has a combination of motion detectors, detail detectors and pattern detectors, of which each output is combined to create the visual experience. Persistence of vision was discovered by the Roman poet Lucretius. Film systems Through experience in the early days of film innovation, it was determined that a frame rate of less than 16 frames per second (frame/s) caused the mind to see flashing images. Audiences still interpret motion at rates as low as ten frames per second or slower (as in a flipbook), but the flicker caused by the shutter of a film projector is distracting below the 16-frame threshold. Modern theatrical film runs at 24 frames a second. This is the case for both physical film and digital cinema systems. It is important to distinguish between the frame rate and the flicker rate, which are not necessarily the same. In physical film systems, it is necessary to pull down the film frame, and this pulling-down needs to be obscured by a shutter to avoid the appearance of blurring; therefore, there needs to be at least one flicker per frame in film. To reduce the appearance of flicker, virtually all modern projector shutters are designed to add additional flicker periods, typically doubling the flicker rate to 48 Hz (single-bladed shutters make two rotations per frame - double-bladed shutters make one rotation per frame), which is less visible. (Some three-bladed projector shutters even triple it to 72 Hz.) In digital film systems, the scan rate may be decoupled from the image update rate. In some systems, such as the Digital Light Processing (DLP) system, there is no flying spot or raster scan at all, so there is no flicker other than that generated by the temporal aliasing of the film image capture. The new film system MaxiVision 48 films at 48 frames per second, which, according to film critic Roger Ebert, offers even a strobeless tracking shot past picket fences. The lack of strobe (as opposed to flicker) is due to the higher sampling rate of the camera relative to the speed of movement of the image across the film plane. This ultra-smooth imaging is called High motion. It is critical for sports and motion simulation, but unpopular for drama. Video systems [[Image:Pac-man flicker.gif|thumbnail|right|200px|The Atari 2600 Pac-Man'''s flickering ghosts were widely criticised. Each of the game's four enemies only appears in one out of every four frames, but because of persistence of vision, this presents the illusion of having four flickering enemies on the screen at once.]] Video records at 50 (Eurasia) or 60 Actually 60 images per 1001ms, commonly rounded to 59.94 or 60 for discussion. (US & Japan) images per second (ips) depending on the national system used; The flicker or refresh rate on a television screen is fixed to one or the other nationally chosen standards. A technique called interlace uses persistence of vision to combine two consecutive images (or fields) to create one frame with higher detail in non-moving areas. Because the fields are exposed and displayed separately, a single TV "frame" can potentially contain motion or even two distinct images. With ordinary video from video cameras, the flicker rate and the image rate are the same. However, when footage shot on 24 Hz film is shown on 60 Hz TV, each film frame is repeated for 2.5 consecutive fields to produce 60 fields per second. (see 3:2 pulldown) In countries using 50 Hz TV, 24 frame/s film is sped up by 4% to produce 25 frames (50 fields) per second. Many modern video systems also decouple display rate from image update, for example, systems using LCD or plasma panels with continuous light output, or intermediate frame buffers that increase the display rate to 100 or 120 fields per second. Such implementations can occur on low-flicker purpose-built CRT TVs, but decoupling can happen inadvertently on any display connected to a HTPC. Computer monitors Aside from a few configurations used in the early 1990s, computer monitors do not use interlacing. They may sometimes be seen to flicker, often in a brightly lit room, and at close viewing distances. The latter effect is due to the greater likelihood that part of the screen will occupy the viewer's peripheral vision, where sensitivity to flickering is greater. Generally, a refresh rate of 85 Hz or above (as found in most modern monitors) is sufficient to minimize flicker at close viewing distances, and all recent computer monitors are capable of at least that rate. Flat-panel Liquid Crystal Display (LCD) monitors do not suffer from flicker even if their refresh rate is 60 Hz or even lower. This is because LCD pixels open to allow a continuous stream of light to pass through until instructed by the video signal to produce a darker color (see also ghosting). CRTs by comparison create a momentary burst of light each time the electron beam strikes a particular point on the CRT. Contemporary LCD Monitor Parameters: Objective and Subjective Analysis (page 3) Cartoon animation This animated cartoon of a galloping horse is displayed at 12 drawings per second, and the fast motion is on the edge of being objectionably jerky. In drawn animation, moving characters are often shot "on twos", that is to say, one drawing is shown for every two frames of film (which usually runs at 24 frames per second), meaning there are only 12 drawings per second. Even though the image update rate is low, the fluidity is satisfactory for most subjects. However, when a character is required to perform a quick movement, it is usually necessary to revert to animating "on ones", as "twos" are too slow to convey the motion adequately. A blend of the two techniques keeps the eye fooled without unnecessary production cost. Animation for most "Saturday morning cartoons" is produced as cheaply as possible, and is most often shot on "threes", or even "fours", i.e. three or four frames per drawing. This translates to only 8 or 6 drawings per second, respectively. Printed media Flip books use this principle. If the book is flipped at a fast enough speed, the illusion of motion is created.

7,781 | MV_Blue_Marlin | MV Blue Marlin carrying USS Cole. Blue Marlin transporting the U.S. Navy minesweepers USS Raven (MHC-61) and USS Cardinal (MHC-60) Sea-Based X-Band Radar enters Pearl Harbor on January 9 2006 on its way to Adak Island, Alaska, transported by MV Blue Marlin. MV Blue Marlin and her sister ship Black Marlin comprise the Marlin class of semi-submersible heavy-lift ship. They were owned by Offshore Heavy Transport of Oslo, Norway from their construction, in April 2000 and November 1999 respectively, until July 6, 2001, when they were purchased by Dockwise Shipping of the Netherlands. They were designed to transport very large semi-submersible drilling rigs, which can weigh 30,000 tons and have a center of gravity around 30 meters (100 ft) above the transport ship's deck. The Marlins are equipped with 38 cabins to accommodate 60 people, a workout room, sauna, and swimming facilities. History The U.S. Navy hired the Blue Marlin from Offshore Heavy Transport to move the destroyer USS Cole (DDG-67) back to the United States after the warship was crippled in Aden, Yemen, by suicide bombers. During the latter part of 2003, work done on the Blue Marlin boosted its capacity and added two retractable propulsors to improve maneuverability. The ship re-entered service in January 2004. Following these improvements, the Blue Marlin delivered the oil platform Thunder Horse, weighing 60,000 tons, to Corpus Christi, Texas for completion. In July 2005 Blue Marlin moved the gas refinery Snøhvit from its construction site in Cádiz to Hammerfest, an 11 day trip. This transport was filmed for the TV show Extreme Engineering on the Discovery Channel, and also the TV show Mega Movers on the History Channel. In November 2005, Blue Marlin left Corpus Christi, Texas, to move the massive Sea-based X-band Radar to Adak, Alaska, via the southern tip of South America and Pearl Harbor, Hawaii. It arrived at Pearl Harbor on January 9, 2006, having traveled 15,000 miles. In January 2007, the Blue Marlin was employed to move two jack-up rigs, the Rowan Gorilla VI and the GlobalSantaFe Galaxy II, from Halifax Harbour to the North Sea.

7,782 | Catenary | Catenaries for different values of the parameter 'a' In physics and geometry, the catenary is the theoretical shape a hanging chain or cable will assume when supported at its ends and acted on only by its own weight. The curve is a hyperbolic cosine which has a U-like shape, similar in appearance to a parabola. History The word catenary is derived from the Latin word catena, which means "chain". The curve is also called the "alysoid", "funicular", and "chainette". Galileo claimed that the curve of a chain hanging under gravity would be a parabola, but this was disproved by Joachim Jungius (1587-1657) and published posthumously in 1669. Swetz, Faauvel, Bekken, "Learn from the Masters", 1997, MAA ISBN 0883857030, pp.128-9 In 1691, Leibniz, Christiaan Huygens, and Johann Bernoulli derived the equation in response to a challenge by Jakob Bernoulli. Huygens first used the term 'catenaria' in a letter to Leibniz in 1690, and David Gregory wrote a treatise on the catenary in 1690. However Thomas Jefferson is usually credited with the English word 'catenary' "Catenary" at Math Words . The application of the catenary to the construction of arches is ancient, as described below; the modern rediscovery and statement is due to Robert Hooke, who discovered it in the context of the rebuilding of St Paul's Cathedral http://links.jstor.org/sici?sici=0035-9149(200105)55%3A2%3C289%3AMAMSTO%3E2.0.CO%3B2-X , possibly having seen Huygens' work on the catenary. In 1671, Hooke announced to the Royal Society that he had solved the problem of the optimal shape of an arch, and in 1675 published an encrypted solution as a Latin anagram cf. the anagram for Hooke's law, which appeared in the next paragraph. in an appendix to his Description of Helioscopes, Arch Design where he wrote that he had found "a true mathematical and mechanical form of all manner of Arches for Building". He did not publish the solution of this anagram The original anagram was "abcccddeeeeeefggiiiiiiiiillmmmmnnnnnooprrsssttttttuuuuuuuux": the letters of the Latin phrase, alphabetized. in his lifetime, but in 1705 his executor provided it as: meaning Euler proved in 1744 that the catenary is the curve which, when rotated about the x-axis, gives the surface of minimum surface area (the catenoid) for the given bounding circle. http://mathworld.wolfram.com/Catenary.html Mathematical description Equation The equation (up to translation and rotation) of a catenary in Cartesian coordinates has the form , where is the hyperbolic cosine function. The scaling factor can be interpreted as the ratio between the horizontal component of the tension on the chain (a constant) and the weight of the chain per unit of length. The Whewell equation for the catenary is . From this the Cesàro equation can be derived by differentiation: . Derivation Let be the external force per unit length acting on a small segment of a chain, and let be the force of tension as a function of , the distance along the chain from some fixed point on it. The forces acting on the segment of the chain between and are the force of tension at one end of the segment, the nearly opposite force at the other end, and the external force acting on the segment which is approximately . The chain is assumed to be in static equilibrium so these forces must balance, therefore . Divide by and take the limit as to obtain . The flexibility of the chain implies that is parallel to the curve of the chain, so we may assume where is the unit tangent vector pointed in positive direction, and is a scalar function of with positive value. We assume the chain has constant mass per unit length and the only external force acting on the chain is that of a uniform gravitational field , so and . Integrating, , where and are constants. By changing the point from which s is measured, we may take , so . From here, we can continue the derivation in two ways. Continue alternative 1 If is the tangential angle of the curve then is parallel to so . Write to combine constants and obtain the Whewell equation for the curve, . The derivation of the curve for an optimal arch is similar except that the forces of tension become forces of compression and everything is inverted. In general, parametric equations can be obtained from a Whewell equation by integrating: To find these integrals, make the substitution (or where is the Gudermannian function). Then and . We can eliminate u to obtain where and are constants to be determined, along with , by the boundary conditions of the problem. Usually these conditions include two points from which the chain is being suspended and the length of the chain. Continue alternative 2 In this alternative method, the use of trigonometric functions is left out of the derivation for as long as possible, for simplicity reasons. Let be the position vector of the chain as functions of . It then follows that is a tangent to the plane, which is automatically parallel to , so Besides, since is the distance along the chain, we have We also have and we have (now without absolute signs) Choose , which will give us a much nicer expression: Splitting up the vectors on both sides gives us two equations: By integration, these irrational functions give us that where , and and is two constants of integration. We can now isolate : where Note that we cannot just move over to the other side of the equation, since is dependent of . We continue: Insert this into the expression for : Other properties A parabola rolled along a straight line traces out a catenary (see roulette) with its focus . Square wheels can roll perfectly smoothly if the road has evenly spaced bumps in the shape of a series of inverted catenary curves. The wheels can be any regular polygon save for a triangle, but one must use the correct catenary, corresponding correctly to the shape and dimensions of the wheels "Roulette: A Comfortable Ride on an n-gon Bicycle" by Borut Levart, Wolfram Demonstrations Project, 2007. . A charge in a uniform electric field moves along a catenary (which tends to a parabola if the charge velocity is much less than the speed of light c). Suspension bridges Hercilio Luz Bridge, Florianópolis, Brazil. Suspension bridges follow a parabolic, not catenary, curve. Free-hanging chains follow the curve of the hyperbolic function above, but suspension bridge chains or cables, which are tied to the bridge deck at uniform intervals, instead follow a parabolic curve, much as Galileo originally claimed. The difference comes from the fact that force exerted is uniform with respect to for the parabola, instead of for the catenary. When suspension bridges are constructed, the suspension cables initially sag as the catenaric function, before being tied to the deck below, and then gradually assume a parabolic curve as additional connecting cables are tied to connect the main suspension cables with the bridge deck below. The inverted catenary arch The catenary is the ideal curve for an arch which supports only its own weight. When the centerline of an arch is made to follow the curve of an up-side-down (ie. inverted) catenary, the arch endures almost pure compression, in which no significant bending moment occurs inside the material. If the arch is made of individual elements (eg., stones) whose contacting surfaces are perpendicular to the curve of the arch, no significant shear forces are present at these contacting surfaces. (Shear stress is still present inside each stone, as it resists the compressive force along the shear sliding plane.) The thrust (including the weight) of the arch at its two ends is tangent to its centerline. The throne room of the Taq-i Kisra in 1824. In antiquity, the curvature of the inverted catenary was intuitively discovered and found to lead to stable arches and vaults. A spectacular example remains in the Taq-i Kisra in Ctesiphon, which was once a great city of Mesopotamia. In ancient Greek and Roman cultures, the less efficient curvature of the circle was more commonly used in arches and vaults. The efficient curvature of inverted catenary was perhaps forgotten in Europe from the fall of Rome to the Middle-Ages and the Renaissance, where it was almost never used, although the pointed arch was perhaps a fortuitous approximation of it. Catenary arches under the roof of Gaudí's Casa Milà, Barcelona, Spain The Catalan architect Antoni Gaudí made extensive use of catenary shapes in most of his work. In order to find the best curvature for the arches and ribs that he desired to use in the crypt of the Church of Colònia Güell, Gaudí constructed inverted scale models made of numerous threads under tension to represent stones under compression. This technique worked well to solve angled columns, arches, and single-curvature vaults, but could not be used to solve the more complex, double-curvature vaults that he intended to use in the nave of the church of the Sagrada Familia. The idea that Gaudi used thread models to solve the nave of the Sagrada Familia is a common misconception, although it could have been used in the solution of the bell towers. The Gateway Arch (looking East). The Gateway Arch in Saint Louis, Missouri, United States follows the form of an inverted catenary. It is 630 feet wide at the base and 630 feet tall. The exact formula is displayed inside the arch. In structural engineering a catenary shell is a structural form, usually made of concrete, that follows a catenary curve. The profile for the shell is obtained by using flexible material subjected to gravity, converting it into a rigid formwork for pouring the concrete and then using it as required, usually in an inverted manner. Catenary arch kiln under construction over temporary form A kiln, a kind of oven for firing pottery, may be made from firebricks with a body in the shape of a catenary arch, usually nearly as wide as it is high, with the ends closed off with a permanent wall in the back and a temporary wall in the front. The bricks (mortared with fireclay) are stacked upon a temporary form in the shape of an inverted catenary, which is removed upon completion. The form is designed with a simple length of light chain, whose shape is traced onto an end panel of the form, which is inverted for assembly. A particular advantage of this shape is that it does not tend to dismantle itself over repeated heating and cooling cycles — most other forms such as the vertical cylinder must be held together with steel bands. Anchoring of marine vessels The catenary form given by gravity is made advantage of in its presence in heavy anchor rodes. An anchor rode (or anchor line) usually consists mostly of chain or cable. Anchor rodes are used by ships, oilrigs, docks, and other marine assets which must be anchored to the seabed. Particularly with larger vessels, the catenary curve given by the weight of the rode presents a lower angle of pull on the anchor or mooring device. This assists the performance of the anchor and raises the level of force it will resist before dragging. With smaller vessels and in shallow water it is less effective Chain, Rope, and Catenary - Anchor Systems For Small Boats . The catenary curve in this context is only fully present in the anchoring system when the rode has been lifted clear of the seabed by the vessel's pull, as the seabed obviously affects its shape while it supports the chain or cable. There is also typically a section of rode above the water and thus unaffected by buoyancy, creating a slightly more complicated curve. Towed cables A truss arch bridge designed by Gustav Eiffel employing an inverted catenary arch When a cable is subject to wind or water flows, the drag forces lead to more general shapes, since the forces are not distributed in the same way as the weight. A cable having radius and specific gravity , and towed at speed in a medium (e.g., air or water) with density , will have an position described by the following equations A.P. Dowling, "The dynamics of towed flexible cylinders. Part 2. Negatively buoyant elements" (1988). Journal of Fluid Mechanics, 187, 533-571. : Here is the tension, is the incident angle, , and is the cable scope. There are three drag coefficients: the normal drag coefficient ( for a smooth cylindrical cable); the tangential drag coefficient (), and (). The system of equations has four equations and four unknowns: , , and , and is typically solved numerically. Critical angle tow Critical angle tow occurs when the incident angle does not change. In practice, critical angle tow is common, and occurs far from significant point forces. Setting leads to an equation for the critical angle: If , the formula for the critical angle becomes or or leading to the rule-of-thumb formula The drag coefficients of a faired cable are more complicated, involving loading functions that account for drag variation as a function of incidence angle. Other uses of the term In railway engineering, a catenary structure consists of overhead lines used to deliver electricity to a railway locomotive, multiple unit, railcar, tram or trolleybus through a pantograph or a trolleypole. These structures consist of an upper structural wire in the form of a shallow catenary, short suspender wires, which may or may not contain insulators, and a lower conductive contact wire. By adjusting the tension in various elements the conductive wire is kept parallel to the centerline of the track, reducing the tendency of the pantograph or trolley to bounce or sway, which could cause a disengagement at high speed. In nonrigid and semi-rigid airships, a catenary curtain is a fabric and cable internal structure used to distribute the weight of the gondola across a large area of the ship's envelope. In conveyor systems, the catenary is the portion of the chain or belt underneath the conveyor that is traveling back to the start. It is the weight of the catenary that keeps tension in the chain or belt. For backpacking tents, a catenary curve along the ridgeline reduces the amount of flap and sag in the material http://www.backpacking.net/makegear/cat-tarp/index.html . this is mainly used on tarpaulins and other ultralight tents.

7,783 | Epic_poetry | Tablet containing a fragment of the Epic of Gilgamesh An epic (from Greek: έπος or επικό "word, story, poem" http://www.etymonline.com/index.php?term=epic ) is a lengthy narrative poem, ordinarily concerning a serious subject containing details of heroic deeds and events significant to a culture or nation. Michael Meyer, The Bedford Introduction to Literature, Bedford/St. Martin's, 2005, p2128. ISBN 0-312-41242-8 Oral poetry may qualify as an epic, and Albert Lord and Milman Parry have argued that classical epics were fundamentally an oral poetic form. Nonetheless, epics have been written down at least since Homer, and the works of Vyasa, Virgil, Dante Alighieri and John Milton would be unlikely to have survived without being written down. The first epics are known as primary, or original, epics. Epics that attempt to imitate these like Virgil's The Aeneid and John Milton's Paradise Lost are known as literary, or secondary, epics. One such epic is the Anglo-Saxon story Beowulf. Another type of epic poetry is epyllion (plural: epyllia) which is a brief narrative poem with a romantic or mythological theme. The term, which means 'little epic', came in use in the Nineteenth century. It refers primarily to the type of erotic and mythological long elegy of which Ovid remains the master; to a lesser degree, the term includes some poems of the English Renaissance, particularly those influenced by Ovid. One suggested example of classical epyllion may be seen in the story of Nisus and Euryalus in Book IX of The Aeneid. Oral epics or world folk epics The first epics were products of preliterate societies and oral poetic traditions. In these traditions, poetry is transmitted to the audience and from performer to performer by purely oral means. Early twentieth-century study of living oral epic traditions in the Balkans by Milman Parry and Albert Lord demonstrated the paratactic model used for composing these poems. What they demonstrated was that oral epics tend to be constructed in short episodes, each of equal status, interest and importance. This facilitates memorization, as the poet is recalling each episode in turn and using the completed episodes to recreate the entire epic as he performs it. Parry and Lord also showed that the most likely source for written texts of the epics of Homer was dictation from an oral performance. Epic: a long narrative poem in elevated stature presenting characters of high position in adventures forming an organic whole through their relation to a central heroic figure and through their development of episodes important to the history of a nation or race. Epics have nine main characteristics: opens in media res. The setting is vast, covering many nations, the world or the universe. begins with an invocation to a muse. starts with a statement of the theme. the use of epithets. includes long lists. features long and formal speeches. shows divine intervention on human affairs. "Star" heroes that embody the values of the civilization. The hero generally participates in a cyclical journey or quest, faces adversaries that try to defeat him in his journey and returns home significantly transformed by his journey. The epic hero illustrates traits, performs deeds, and exemplifies certain morals that are valued by the society from which the epic originates. Many epic heroes are recurring characters in the legends of their native culture. Conventions of epics: Praepositio: Opens by stating the theme or cause of the epic. This may take the form of a purpose (as in Milton, who proposed "to justify the ways of God to men"); of a question (as in the Iliad, where Homer asks the Muse which god it was who caused the war); or of a situation (as in the Song of Roland, with Charlemagne in Spain). Invocation: Writer invokes a Muse, one of the nine daughters of Zeus. The poet prays to the Muses to provide him with divine inspiration to tell the story of a great hero. (This convention is obviously restricted to cultures which were influenced by European Classical culture: the Epic of Gilgamesh, for example, or the Bhagavata Purana would obviously not contain this element) In medias res: narrative opens "in the middle of things", with the hero at his lowest point. Usually flashbacks show earlier portions of the story. Enumeratio: Catalogues and genealogies are given. These long lists of objects, places, and people place the finite action of the epic within a broader, universal context. Often, the poet is also paying homage to the ancestors of audience members. Epithet: Heavy use of repetition or stock phrases: e.g., Homer's "rosy-fingered dawn" and "wine-dark sea." Literate societies have often copied the epic format; the earliest European examples of which the text survives are the Argonautica of Apollonius of Rhodes and Virgil's Aeneid, which follow both the style and subject matter of Homer. Other obvious examples are Nonnus' Dionysiaca, Tulsidas' Sri Ramacharit Manas. Notable epic poems The first page of the Beowulf manuscript This list can be compared with two others, national epic and list of world folk-epics. According to that article, world folk epics are those which are not just literary masterpieces but also an integral part of the world view of a people, originally oral, later written down by one or several authors.

7,785 | False_Claims_Act | The False Claims Act (, also called the "Lincoln Law") is an American federal law which allows people who are not affiliated with the government to file actions against federal contractors claiming fraud against the government. The act of filing such actions is informally called "whistleblowing." Persons filing under the Act stand to receive a portion (usually about 15-25 percent) of any recovered damages. The Act provides a legal tool to counteract fraudulent billings turned in to the Federal Government. Claims under the law have been filed by persons with insider knowledge of false claims which have typically involved health care, military, or other government spending programs. History The American Civil War (1861–1865) was marked by fraud on all levels in the Union north and the Confederate south. Some say the False Claims Act came about because of bad mules. During the Civil War, unscrupulous early day defense contractors sold the Union Army decrepit horses and mules in ill health, faulty rifles and ammunition, and rancid rations and provisions among other unscrupulous actions. Oklahoma Bar Association The False Claims Act, passed by Congress on March 2, 1863, was an effort by the USA to respond to entrenched fraud where the official Justice Department was reticent to prosecute fraud cases. Importantly, a reward was offered in what is called the "qui tam" provision, which permits citizens to sue on behalf of the government and be paid a percentage of the recovery. Qui tam is short for the Latin phrase, "qui tam pro domino rege quam pro se ipso in hac parte sequitur," which means, "he who brings a case on behalf of our lord the King, as well as for himself." In a qui tam action, the citizen filing suit is called a "relator." In a 2008 case, Allison Engine Co. v. United States ex rel. Sanders, the United States Supreme Court considered whether a false claim had to be presented directly to the Federal government, or if it merely needed to be paid with government money, such as a false claim by a subcontractor to a prime contractor. The Court found that the claim need not be presented directly to the government, but that the false statement must be made with the intention that it will be relied upon by the government in paying, or approving payment of, a claim. Opinion of the Court, Allison Engine Co. v. United States ex rel. Sanders, 553 U. S. __ (2008), part II(C). The Fraud Enforcement and Recovery Act of 2009 reversed the Court's decision and made the types of fraud to which the False Claims Act applies more explicit. Provisions The Act establishes liability when any person or entity improperly receives from or avoids payment to the Federal government—tax fraud excepted. In summary, the Act prohibits: Knowingly presenting, or causing to be presented to the Government a false claim for payment; Knowingly making, using, or causing to be made or used, a false record or statement to get a false claim paid or approved by the government; Conspiring to defraud the Government by getting a false claim allowed or paid; Falsely certifying the type or amount of property to be used by the Government; Certifying receipt of property on a document without completely knowing that the information is true; Knowingly buying Government property from an unauthorized officer of the Government, and; Knowingly making, using, or causing to be made or used a false record to avoid, or decrease an obligation to pay or transmit property to the Government. The most commonly used of these provisions are the first and second, prohibiting the presentation of false claims to the government and making false records to get a false claim paid. By far the most frequent cases involve situations in which a defendant—usually a corporation but on occasion an individual—overcharges the federal government for goods or services. Other typical cases entail failure to test a product as required by the rigorous government specifications or selling defective products. The False Claims Act was amended in 1943 to, most notably, reduce the relator's share of the recovered proceeds.* The law was again amended in 1986. By that time, there was great concern that the national deficit had risen dangerously and President Ronald Reagan had declared that a vast amount of government spending was being misused through waste and fraud. After the 1986 amendments strengthening the Act were passed (see below), the Act was used primarily against defense contractors. By the late 1990s, however, the focus had shifted to health care fraud, which now accounts for the majority of cases filed by whistleblowers and by the government. Under the False Claims Act, the Department of Justice is authorized to pay rewards to those who report fraud against the federal government in an amount of between 15 and 30 percent of what it recovers based upon the whistleblower's report. Certain claims are not actionable, including: certain actions against armed forces members, members of Congress, members of the judiciary, or senior executive branch officials ; claims, records, or statements made under the Internal Revenue Code of 1986 which would include tax fraud ; There are unique procedural requirements in False Claims Act cases. For example: a complaint under the False Claims Act must be filed under seal; the complaint must be served on the government but must not be served on the defendant; the complaint must be buttressed by a comprehensive memorandum, not filed in court, but served on the government detailing the factual underpinnings of the complaint. 1986 changes (False Claims Act Amendments of 1986 () The elimination of the "government possession of information" bar against qui tam lawsuits; The establishment of defendant liability for "deliberate ignorance" and "reckless disregard" of the truth; Restoration of the "preponderance of the evidence" standard for all elements of the claim including damages; Imposition of treble damages and civil fines of $5,000 to $10,000 per false claim; Increased rewards for qui tam plaintiffs of between 15-30 percent of the funds recovered from the defendant; Defendant payment of the successful plaintiff's expenses and attorney's fees, and; Employment protection for whistleblowers including reinstatement with seniority status, special damages, and double back pay. Practical application of the law The False Claims Act has a detailed process for making a claim under the Act. Mere complaints to the government agency is insufficient to bring claims under the Act. A complaint (lawsuit) must be filed in U.S. District Court (federal court) in camera (under seal). After an investigation by the Department of Justice within 60 days, or frequently several months after an extension is granted, the Department of Justice decides whether it will pursue the case. If the case is pursued, the amount of the reward is less than if the Department of Justice decides not to pursue the case and the plaintiff/relator continues the lawsuit himself. However, the success rate is higher in cases that the Department of Justice decides to pursue. Technically, the government has several options in handing cases. These include: 1) intervene in one or more counts of the pending qui tam action. This intervention expresses the Government’s intention to participate as a plaintiff in prosecuting that count of the complaint. Fewer than 25% of filed qui tam actions result in an intervention on any count by the Department of Justice. 2) decline to intervene in one or all counts of the pending qui tam action. If the United States declines to intervene, the relator may prosecute the action on behalf of the United States, but the United States is not a party to the proceedings apart from its right to any recovery. This option is frequently used by relators and their attorneys. 3) move to dismiss the relator’s complaint, either because there is no case, or the case conflicts with significant statutory or policy interests of the United States. In practice, there are two other options for the Department of Justice: 4) settle the pending qui tam action with the defendant prior to the intervention decision. This usually, but not always, results in a simultaneous intervention and settlement with the Department of Justice (and is included in the 25% intervention rate). 5) advise the relator that the Department of Justice intends to decline intervention. This usually, but not always, results in dismissal of the qui tam action. False Claims Act Cases: Government intervention in Quitam (whistleblower) suits - Memo There is case law where claims may be prejudiced if disclosure of the alleged unlawful act has been reported in the press, if complaints were filed to an agency instead of filing a lawsuit, or if the person filing a claim under the act is not the first person to do so. Individual states in the U.S. have different laws regarding whistleblowing involving state governments. State False Claims Acts Several states have also created False Claims Act statutes to protect their state against fraud by including qui tam provisions, enabling them to recover money at the state level. Many of these laws mirror the federal False Claims Act and simply apply it to the state's jurisdiction. Michigan and Tennessee have specifically limited their False Claims Acts to merely protect their Medicaid systems The California False Claims Act was enacted in 1987, but lay relatively dormant until the early 1990s, when public entities, frustrated by what they viewed as a barrage of unjustified and unmeritorious claims, began to employ the False Claims Act as a defensive measure. Recent developments in the California False Claims Act reduce the defenses contractors have to false claim prosecutions, by stripping away immunities that were believed to apply to certain classes of statements and claims. As a result, contractors can expect to see their payment claims answered by false claims accusations with increasing frequency. See also Medicare Fraud War profiteering Fr.

7,786 | Franconia | The Franconian coat of arms Franconia () is a region of Germany comprising the northern parts of the modern state of Bavaria, a part of southern Thuringia, and a much smaller region in northeastern Baden-Württemberg called Heilbronn-Franken. The Bavarian part is made up of the administrative regions of Lower Franconia (Unterfranken), Middle Franconia (Mittelfranken), and Upper Franconia (Oberfranken). Franconia (just like France) is named after the Germanic tribe of the Franks. This tribe played a major role after the breakdown of the Roman Empire and colonised large parts of medieval Europe. Modern day Franconia comprises only a very tiny and rather remote part of the settlement area of the ancient Franks. In German, Franken is used for both modern day Franconians and the historic Franks, which leads to some confusion. The historic Frankish Empire, Francia, is actually the common precursor of France and Germany. In 843 the Treaty of Verdun led to the partition of Francia into West Francia (modern day France) and East Francia (modern day Germany). Frankreich, the German word for "France", literally means "the Frankish Empire". Stem Duchy of Franconia The Holy Roman Empire at the beginning of the Salic dynasty. East Francia was made up of four stem duchies, one of them was the Duchy of Franconia. The historic duchy of Franconia extended further west to Speyer, Mainz, and Worms (west of the Rhine) than modern day Franconia and even included Frankfurt (ford of the Franks). Sometime around 906, Conrad of the Conradine dynasty succeeded in establishing his ducal hegemony over Franconia. At the failure of the direct Carolingian male line in 911, Conrad was acclaimed King of the Germans, largely because of his weak position in his own duchy. Franconia, like Alamannia, was not as united as Saxony or Bavaria and the position of duke was often disputed between the chief families. Conrad had granted Franconia to his brother Eberhard on his succession; but when Eberhard rebelled against Otto I in 938, he was deposed from his duchy, and, rather than appoint a new duke from his own circle, Otto divided the threatening power of the duchy among the great ecclesiastics with and through whom he ruled, who had remained faithful to his cause: the Bishop of Würzburg and the Abbot of Fulda (939). They were later joined (1008) by a new bishopric erected on former ducal territory: Bamberg. Thenceforth the great abbeys and episcopal seats that Saint Boniface and his successors had established in southwestern Germany had a monopoly on temporal office in Franconia, on a par with the counts of lands further west. They had another virtue in the Ottonian scheme: as celibates they were less likely to establish hereditary lineages. By contrast, Otto's son-in-law, Conrad the Red, whom he had installed as Duke of Lorraine in 944, extended his power base in Franconia. Divided Franconia In the High Middle Ages, Franconia came to be divided into two distinct regions, though these regions were not coherent territories with distinct governments. Rather, they were culturally different regions which came to be dominated by different political and religious forces and thus came under the de facto "rule" of different bodies. Rhenish Franconia Rhenish Franconia (Rheinfranken) was the western half of Franconia, immediately east of the Rhine. It was the heartland of the Salian dynasty, which provided four emperors in the 11th and 12th centuries: Conrad II, Henry III, Henry IV, and Henry V. Rhenish Franconia contained the ancient cities of Mainz, Speyer, and Worms, the latter two being countships within the hands of the descendants of Conrad the Red (the Salians). These counts were sometimes referred to informally, on account of the great power in the region, as dukes of Franconia. Rhenish Franconia was actually governed, however, as a constellation of small states, like the free cities (Frankfurt and Worms), the bishoprics (Mainz, Speyer, and Worms), and the Landgraviate of Hesse. Alongside these powerful entities there were many smaller, petty states. In 1093, the Salian Franconian territories were granted as a fief to the Count Palatine of Aachen, a territory that would evolve into the important German principality of the Rhenish Palatinate. In this way, Rhenish Franconia was divided and extinguished. Successor States of Western Franconia The following are the most important of the states that had formed on the territory of Western (or Rhenish) Franconia by the 13th century: Archbishopric of Mainz Bishopric of Speyer Abbacy of Hersfeld Margraviate of Baden County Palatine of the Rhine County of Calw County of Hesse County of Katzenelnbogen County of Leiningen County of Nassau County of Nidda Rau and Rhine County County of Solms County of Sponheim County of Waldeck County of Weissenburg County of Wied Wild County County of Wittgenstein County of Ziegenhain County of Zweibrücken Eastern Franconia In 1115, Henry V awarded the territory of Eastern Franconia (Ostfranken) to his nephew Conrad of Hohenstaufen, who used the title "Duke of Franconia." Franconia remained a Hohenstaufen power base until 1168, when the Bishop of Würzburg was formally ceded the ducal rights in Eastern Franconia. The name "Franconia" fell out of usage, but in 1500 the Franconian Circle was created. Also the bishop of Würzburg had revived it in his own favour in 1442 and held it until the reforms of Napoleon Bonaparte abolished it. It should be noted that the Bishop of Würzburg was more properly the Duke in Franconia (Herzog in Franken) rather than the Duke of Franconia (Herzog von Franken) during this time although both titles were used. Successor States of Eastern Franconia As of the 13th century, the following states, among others, had formed in the territory of the former Duchy: Bishopric of Würzburg Abbacy of Fulda County of Abenberg County of Henneberg County of Hohenlohe County of Lauffen County of Löwenstein County of Rieneck County of Truhendingen County of Vaihingen County of Wertheim County of Wiltberg Modern Franconia Map of modern Franconia map of the Franconia (wine region) Most of modern day Franconia became Bavarian in 1803 thanks to Bavaria's alliance with Napoleon. Culturally it is in many ways different from Bavaria proper ("Altbayern", Old Bavaria), however. The ancient name was resurrected in 1837 by Ludwig I of Bavaria. During the Nazi period, Bavaria was broken up into several different Gaue, including Franconia and Main-Franconia. While Old Bavaria is overwhelmingly Roman Catholic, Franconia is a mixed area. Lower Franconia and the western half of Upper Franconia (Bamberg, Lichtenfels, Kronach) is predominantly Catholic, while most of Middle and the eastern half of Upper Franconia (Bayreuth, Hof, Kulmbach) are predominantly Protestant (Evangelical Church in Germany). The city of Fürth in Middle Franconia historically (before 1933–1938) had a large Jewish population; Henry Kissinger was born there. East Franconian German is very different from the Austro-Bavarian language. Most Franconians do not call themselves Bavarians, but their insistence on this point is generally a lighthearted matter in modern times. In fact, Franconians will most likely take umbrage at insults directed at Bavaria. Even if there is no Franconian state, red and white are regarded as state colours (Landesfarben) of Franconia. The existence of the region of Heilbronn-Franken in Baden-Württemberg is largely ignored outside this state.

7,787 | Cryogenics | In physics, cryogenics is the study of the production of very low temperature (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures. Rather than the familiar temperature scales of Fahrenheit and Celsius, cryogenicists use the Kelvin (and formerly Rankine) scales. A person who studies elements under extremely cold temperature is called a cryogenicist. Definitions and distinctions The terms cryogenics, cryobiology and cryonics are frequently confused. Other new terms with the prefix cryo- have also been introduced. Cryogenics The branches of physics and engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures. Cryobiology The branch of biology involving the study of the effects of low temperatures on organisms (most often for the purpose of achieving cryopreservation). Cryonics The emerging medical technology of cryopreserving humans and animals with the intention of future revival. Researchers in the field seek to apply the results of many sciences, including cryobiology, cryogenics, rheology, emergency medicine, etc. Cryoelectronics The field of research regarding superconductivity at low temperatures. Cryotronics The practical application of cryoelectronics. Etymology The word cryogenics means "the production of freezing cold"; however the term is used today as a synonym for the low-temperature state. It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins. The workers at the National Institute of Standards and Technology at Boulder, Colorado have chosen to consider the field of cryogenics as that involving temperatures below –180 °C (93.15 K). This is a logical dividing line, since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below -180 °C while the Freon refrigerants, hydrogen sulfide, and other common refrigerants have boiling points above -180 °C. Industrial application Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. Liquid nitrogen is the most commonly used element in cryogenics and is legally purchasable around the world. Liquid helium is also commonly used and allows for the lowest attainable temperatures to be reached. These liquids are held in either special containers known as Dewar flasks, which are generally about six feet tall (1.8 m) and three feet (91.5 cm) in diameter, or giant tanks in larger commercial operations. Dewar flasks are named after their inventor, James Dewar, the man who first liquefied hydrogen. Museums typically display smaller vacuum flasks fitted in a protective casing. Cryogenic transfer pumps are the pumps used on LNG piers to transfer Liquefied Natural Gas from LNG Carriers to LNG storage tanks. Cryogenic processing The field of cryogenics advanced during World War II when scientists found that metals frozen to low temperatures showed more resistance to wear. Based on this theory of cryogenic hardening, the commercial cryogenic processing industry was founded in 1966 by Ed Busch. With a background in the heat treating industry, Busch founded a company in Detroit called CryoTech in 1966. Though CryoTech later merged with 300 Below to create the largest and oldest commercial cryogenics company in the world, they originally experimented with the possibility of increasing the life of metal tools to anywhere between 200%-400% of the original life expectancy using cryogenic tempering instead of heat treating. This evolved in the late 1990s into the treatment of other parts (that did more than just increase the life of a product) such as amplifier valves (improved sound quality), baseball bats (greater sweet spot), golf clubs (greater sweet spot), racing engines (greater performance under stress), firearms (less warping after continuous shooting), knives, razor blades, brake rotors and even pantyhose. The theory was based on how heat-treating metal works (the temperatures are lowered to room temperature from a high degree causing certain strength increases in the molecular structure to occur) and supposed that continuing the descent would allow for further strength increases. Using liquid nitrogen, CryoTech formulated the first early version of the cryogenic processor. Unfortunately for the newly-born industry, the results were unstable, as components sometimes experienced thermal shock when they were cooled too quickly. Some components in early tests even shattered because of the ultra-low temperatures. In the late twentieth century, the field improved significantly with the rise of applied research, which coupled microprocessor based industrial controls to the cryogenic processor in order to create more stable results. Cryogens, like liquid nitrogen, are further used for specialty chilling and freezing applications. Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately -100 °C. Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment. The freezing of foods and biotechnology products, like vaccines, requires nitrogen in blast freezing or immersion freezing systems. Certain soft or elastic materials become hard and brittle at very low temperatures, which makes cryogenic milling (grinding) an option for some materials that cannot easily be milled at higher temperatures. Fuels Another use of cryogenics is cryogenic fuels. Cryogenic fuels, mainly liquid hydrogen, have been used as rocket fuels. (Oxygen is used as an oxidizer of hydrogen, but oxygen is not, strictly speaking, a fuel.) For example, NASA's workhorse space shuttle uses cryogenic hydrogen fuel as its primary means of getting into orbit, as did all of the rockets built for the Soviet space program by Sergei Korolev. (This was a bone of contention between him and rival engine designer Valentin Glushko, who felt that cryogenic fuels were impractical for large-scale rockets such as the ill-fated N-1 rocket spacecraft.) Russian aircraft manufacturer Tupolev is currently researching a version of its popular design Tu-154 with a cryogenic fuel system, known as the Tu-155. The plane uses a fuel referred to as liquefied natural gas or LNG, and made its first flight in 1989. Production Cryogenic cooling of devices and material is usually achieved via the use of liquid nitrogen, liquid helium, or a cryocompressor (which uses high pressure helium lines). Detectors Cryogenic temperatures, usually well below 77 K (−196 °C) are required to operate cryogenic detectors. Further reading Haselden, G. G.

7,788 | Five-spice_powder | Five-spice powder is a mixture of five spices http://www.theepicentre.com/Spices/chinesefivespice.html http://www.schwartz.co.uk/productdetail.cfm?id=5198 used in Chinese cuisine. One common recipe includes tunghing or "Chinese cinnamon" (also known as rougui, the ground bark of the cassia tree, a close relative of true cinnamon), powdered cassia buds, powdered star anise and anise seed, ginger root, and ground cloves. Another recipe for the powder consists of huajiao (Sichuan pepper), bajiao (star anise), rougui (cassia), cloves, and fennel seeds. It is used in most recipes for Cantonese roasted duck, as well as beef stew. It is also used as a marinade for Vietnamese broiled chicken. The five-spice powder mixture has followed the Chinese diaspora and has been incorporated into other national cuisines throughout Asia. The formulae are based on the Chinese philosophy of balancing the yin and yang in food. Although this spice is used in restaurant cooking, many Chinese households do not use it in day-to-day cooking. In Hawaii, some restaurants have it on the table. A versatile seasoned salt can be easily made by stir-frying common salt with Five-spice powder under low heat in a dry pan until the spice and salt are well mixed.

7,789 | L_cut | An L cut, also known as a split edit, is an edit transition from one shot to another in film or video, where the picture transition does not occur coincidentally with the audio transition. This is often done to enhance the aesthetics or flow of the film (for example--a conversation between two people can feel like a tennis match without L cuts. L cuts allow the audience to see the reactionary impulse to speak, or the aftermath of speaking rather than simply the act of speaking.) L cuts are also used to hide transitions between scenes. They can be very effective in editing dialog scenes shot with a single camera using multiple takes. The ability to cut the picture/video separately from the sound/audio allows the sound from the various takes to flow smoothly, even though the picture cuts are at different places. In longer shots, this allows the editor to use the picture from one take with the sound from another take if the dialog reading is better. A prominent example of an L cut occurs in the film The Silence of the Lambs when Clarice is leaving her first interview with Dr. Lecter. She has just been humiliated and remembers her father arriving home from work one day when she was a child; after he picks her up and spins her around, the camera pans over to a passing truck and tilts up to the sky. Then we hear Clarice's sobs and cut back to her outside the mental institution, leaning on her car and crying. The name of the cut refers to the shape of the cut pieces of the film Cassidy, Kyle, "Basic Training: Tricks for J and L Cuts" Videomaker vol. 22, no. 12 (June 2008): 56-58. - the audio track is cut somewhat after (or before) the last frame of video, resulting in roughly L-shaped film ends, as the video and audio parts of film are in tracks, one below, one above, on the film itself.

7,790 | Amalric_of_Bena | Amalric of Bena ( Amaury de Bène or Amaury de Chartres; Almaricus, Amalricus, Amauricus; died c. 1204-1207) was a French theologian, after whom the Amalricians are named. Biography He was born in the latter part of the 12th century at Bennes, a village between Ollé and Chauffours in the diocese of Chartres. He taught philosophy and theology at the University of Paris and enjoyed a great reputation as a subtle dialectician; his lectures developing the philosophy of Aristotle attracted a large circle of hearers. In 1204 his doctrines were condemned by the university, and, on a personal appeal to Pope Innocent III, the sentence was ratified, Amalric being ordered to return to Paris and recant his errors. His death was caused, it is said, by grief at the humiliation to which he had been subjected. In 1209 ten of his followers were burnt before the gates of Paris, and Amalric's own body was exhumed and burnt and the ashes given to the winds. The doctrines of his followers, known as the Amalricians, were formally condemned by the fourth Lateran Council in 1215. Propositions Amalric appears to have derived his philosophical system from Eriugena, whose principles he developed in a one-sided and strongly pantheistic form. Three propositions only can with certainty be attributed to him: that God is all (omnia sunt deus) and thus all things are one because whatever is, is God (omnia unum, quia quidquid est, est Deus); that every Christian is bound to believe that he is a member of the body of Christ, and that this belief is necessary for salvation; that he who remains in love of God can commit no sin. Because of the first proposition, God himself is thought as invisible and only recognizable in his creation. These three propositions were further developed by his followers, who maintained that God revealed Himself in a threefold revelation, the first in the Biblical patriarch Abraham, marking the epoch of the Father; the second in Jesus Christ, who began the epoch of the Son; and the third in Amalric and his disciples, who inaugurated the era of the Holy Ghost. Amalricians taught: Hell is ignorance, therefore Hell is within all men, "like a bad tooth in a mouth"; God is identical with all that is, even evil belongs to God and proves God's omnipotence; A man who knows that God works through everything cannot sin, because every human act is then the act of God; A man who recognizes the truth that that God works through everything is already in Heaven and this is the only resurrection. There is no other life; man's fulfilment is in this life alone. Due to persecutions, this sect does not appear to have long survived the death of its founder. Not long after the burning of ten of their members (1210), the sect itself lost its importance, while some of the surviving Amalricians became Brethren of the Free Spirit http://www.pinselpark.org/geschichte/einzel/p0375_mittelalter/r_haeresie.html (German) . Amalric was a believer in Apocatastasis, the belief that all people would eventually be saved. "Apocatastasis". Catholic Encyclopedia. 1913.

7,791 | Demographics_of_the_Central_African_Republic | This article is about the demographic features of the population of the Central African Republic, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. Demographics of Central African Republic, Data of FAO, year 2005 ; Number of inhabitants in thousands. There are more than 80 ethnic groups in the Central African Republic (CAR), each with its own language. About 50% are Baya-Mandjia, 40% Banda (largely located in the northern and central parts of the country), and 7% are M'Baka (southwestern corner of the CAR). Sangho, the language of a small group along the Oubangui River, is the national language spoken by the majority of Central Africans. Only a small part of the population has more than an elemental knowledge of French, the official language. More than 55% of the population of the CAR lives in rural areas. The chief agricultural areas are around the Bossangoa and Bambari. Bangui, Berberati, Bangassou, and Bossangoa are the most densely populated urban centers.

7,792 | Hoosier_Hysteria | Hoosier Hysteria is the state of excitement surrounding the Indiana high school basketball tournament. In part, the excitement stemmed from the inclusion of all Indiana high schools in the same tournament, where a small town's David might knock off a large city's Goliath. The most famous example occurred in 1954, when Milan (enrollment 161) defeated Muncie Central (enrollment over 1,600) to win the State title. The plot of the now famous movie, Hoosiers, was based on the story of the 1954 Milan team and seems to typify the hysteria related to basketball in the state of Indiana. Indiana's passion for basketball was observed and written about by basketball's inventor, James Naismith. In 1925, Naismith visited an Indiana basketball state finals game along with 15,000 screaming fans and later wrote, that while it was invented in Massachusetts, "basketball really had its origin in Indiana, which remains the center of the sport." Hoosiers have a traditional love for basketball similar to the love for football in Texas, and Minnesotans' love for hockey. It truly is one of the State's most cherished traditions. High School Hysteria One-Class Tradition Historically, each of the several hundred small towns of Indiana had its own small school system. Before consolidation of many of these rural school districts in the last half of the twentieth century, Indiana high schools had fewer students than those of most other states; basketball was a natural game for these schools since it only required five starters and a few reserves. Even one or two great basketball players could make a high school team a powerhouse, and nearly every Indiana town dreamt of such glory. The Franklin Wonder Five was the first team to win the state championship in three consecutive years, from 1920-1922. This accomplishment would not be matched for over six decades. The team was led by Fuzzy Vandivier. After Milan's Miracle in the 1950s, no school with an enrollment of less than 500 won another boys' State title under the all-comers format. As school consolidation became more common and as more rural residents migrated to cities making large high schools grow even larger, smaller high schools had only a mismatch to look forward to come tournament time, as success concentrated in Indiana's large urban and suburban schools. Starting with the 1997-1998 season, Indiana established a controversial four-class system for its basketball championship, although many other sports remain single-class. The state's move to this new system has, to some extent, diminished the phenomenon and public opinion is widely split on the merits of "class basketball." Aside from the "Milan Miracle," the story of Crispus Attucks High School ranks as one of the greatest in Indiana high school basketball tradition. In 1955, the year after Attucks had lost in the semistate final (state quarterfinals) to Milan's championship team, Attucks gained fame by winning the Indiana state championship, becoming the first all-black school in the nation to win a state title. Crispus Attucks repeated as champions in 1956, becoming the first Indiana high school team to complete a season undefeated. The Attucks teams of 1954 through 1956 were led by Oscar Robertson. Both stories, Milan and Crispus Attucks, are memorialized for their accomplishments and tradition at the Indiana State Museum as well as at the Indiana Basketball Hall of Fame in New Castle, Indiana. A highlight of the single-class tournament was the 1990 State Championship game, in which the paid attendance was over 40,000 fans. This phenomenal turnout of fans who witnessed Damon Bailey's Bedford-North Lawrence Stars win the State Championship stands as the largest crowd ever to witness a high school basketball game. After the 1997 season (when Bloomington North won the final single-class State Championship), the IHSAA controversially did away with the single-class system, effectively ending the run of single-class champions in Indiana. There are many in Indiana who lament this loss, and who feel that Hoosier Hysteria has been significantly lessened thereby. High school gymnasiums Perhaps one of the more telling signs of the passion and commitment to basketball at the high school level is the number and size of large basketball gymnasiums in the state. With considerable cost and effort, Indiana boasts nine of the ten largest high school gyms in the country, and a purported eighteen of the top twenty. Seventeen venues in Indiana today boast a capacity of over 6,000. College Hysteria Hoosier Hysteria may have its roots firmly planted in the high school game, but the college tradition brings its own depth to Indiana's passion. In NCAA Division I basketball, Indiana's colleges and universities have a storied past. Big Ten rivals Indiana University and Purdue University are the most notable, with national and conference championships to boast. Yet, even the more football-oriented University of Notre Dame and smaller schools such as Ball State University, Butler University, the University of Evansville, Indiana State University, and Valparaiso University add to the mix. Vincennes University boasts an outstanding national tradition in the junior college ranks. In recent years, even the largely-commuter campus of IUPUI and the Division II University of Indianapolis and University of Southern Indiana have added their own successes to the legend of Indiana basketball. Wabash College won the Men's Division III NCAA Championship in 1982; DePauw and Manchester were Div III National Finalists. It is safe to say that the terms "Final Four" and "March Madness" have grown out of the tradition of Hoosier Hysteria. Ball State Cardinals The Ball State Cardinals have won several conference championships and earned a number of NCAA Tournament berths over the years, including: Seven Mid-American Conference Season Championships Seven Mid-American Conference (MAC) Tournament Championships (and subsequent NCAA Tournament appearances) Bonzi Wells, a Muncie, Indiana native, was a four-year letterwinner at Ball State, finishing his career as the Mid-American Conference's all-time leading scorer, and leading the NCAA in steals. Ball State's highest finish in the NCAA Tournament came in 1990, when they defeated Gary Payton's Oregon State Beavers and Coach Denny Crum's Louisville Cardinals before falling to eventual champion UNLV by 2, 69-67. Butler Bulldogs Home to the legendary Hinkle Fieldhouse, where Indiana High School Athletic Association Championships were held for many years (including Milan's 1954 championship), Butler University also is notable for its men's and women's basketball teams. The Bulldogs advanced to the Sweet 16 of the NCAA Tournament in the 2003 and 2007 seasons. In 2006, the Bulldogs won the 2006 Preseason NIT, beating most notably Indiana and Notre Dame to reach the semifinals in New York City. Behind a strong performance from guard A.J. Graves, the Bulldogs defeated Tennessee and Gonzaga at Madison Square Garden. Evansville Purple Aces The Evansville Aces have won five national championships in the NCAA College Division (now known as Division II): 1959, 1960, 1964, 1965 (29-0 record), and 1971. This ranks second all-time. After joining the NCAA's Division I in 1977, Evansville was a charter member of the Midwest Collegiate Conference, now known as the Horizon League. The Aces won or shared the MCC regular season title in 1982, 1987, 1989, 1992, and 1993. They also won the conference tournament title in 1982, 1992, and 1993. The Aces are now a member of the Missouri Valley Conference, and won the 1999 regular season title. Legendary Aces coach Arad McCutchan was the first NCAA College Division coach selected to the Naismith Basketball Hall of Fame. Indiana Hoosiers Indiana's collegiate basketball squad, the Indiana Hoosiers men's basketball team has several championships to their credit: Five NCAA National Championships (1940, 1953, 1976, 1981, 1987), placing them in a tie for third most all-time Twenty Big Ten Championships (including four-in-a-row, from 1973 to 1976), currently the second most all-time Also, Indiana completed the most recent undefeated season in Division I men's college basketball, going 32-0 in the 1975-76 season under Hall of Fame coach Bob Knight. The Hoosiers' five NCAA Championships are the third-most in history, tied with UNC trailing UCLA (11) and Kentucky (7). Their eight trips to the Final Four ranks seventh on the all-time list. The Hoosiers have made 32 appearances in the NCAA Men's Division I Basketball Tournament (fifth-most in NCAA history). In those 32 appearances, Indiana has posted 52 victories, the sixth-most in NCAA history. Indiana State Sycamores Led by the legendary French Lick standout Larry Bird, Indiana State was the runner-up in the 1979 NCAA Tournament. They lost to Magic Johnson's Michigan State Spartans. Indiana State, led by All-American Jerry Newsom, was the runner-up in the 1968 NCAA College Division championship game. Indiana State won the 1950 NAIA championship game. Seven team players played for Head Coach John Longfellow as the United States' Gold Medal Basketball team at the 1951 Pan-American Games. Indiana State was the runner-up in the 1946 and 1948 NAIA championship games. The 1948 team was coached by the legendary John Wooden; it is the only Championship game loss in Coach Wooden's career. In 1947, Wooden's basketball team won the conference title and received an invitation to the NAIA National Tournament in Kansas City. Wooden refused the invitation citing the NAIA's policy banning African American players. A member on the Indiana State Sycamores' team was Clarence Walker, an African-American athlete from East Chicago, Indiana. In 1948 the NAIA changed this policy and Wooden guided his team to the NAIA final, losing to Louisville. That year, Walker became the first African-American to play in ANY post-season intercollegiate basketball tournament. Indiana State finished third in 1953 and fourth in the 1949 NAIA tourney. Two MVC Regular Season Championships and two MVC Tournament Championships Eight Indiana Collegiate Conference (ICC) Regular Season Championships Notre Dame Fighting Irish Like Purdue, the 1936 Men's Irish Basketball team won the Helms Foundation National Championship. The Irish women won the National Championship in 2001. Purdue Boilermakers With their only National Championship coming in the days before the NCAA Tournament, the Purdue Boilermakers have a strong basketball history: National Championship in 1932 (sponsored by the Helms Athletic Foundation, seven years before the NCAA sponsored a basketball championship) One NIT Championship (1974); the first for the Big Ten Conference and two Runner-up finishes (1979, 1982) and a third place finish (1981) Twenty-One (21) Big Ten Championships (including a "Three-Pete" - a play on their mascot - from 1994 to 1996 and from 1934-1936.) The most all-time. Currently second all-time in Big Ten Conference victories with 848. The reigning Big Ten Tournaments Champions. The women Boilermakers have one National Championship (1999), one National Runner-up (2001), seven Big Ten Championships, and have won six of the thirteen women's Big Ten Tournaments. USI Screaming Eagles The USI Screaming Eagles, led by Bruce Pearl, won the 1995 Division II National Championship and were runners-up in 1994 and 2004. Valparaiso Crusaders Nine Summit League regular season championships. Eight Summit League tournament championships. Memorable run in the 1998 NCAA Tournament following The Shot by Bryce Drew. Vincennes Trailblazers The Vincennes program began in 1903, however, no teams were formed from 1910-1912 and 1931-1950. The Vincennes University men's basketball program is the 4th winningest junior college program in the country, with 1,470 victories. The Trailblazers trail Southeastern Iowa Community College (1,519), Moberly, Mo., (1,505) and Hutchinson, Kan., with 1,490. The Trailblazers' 3 National Titles place them 3rd in titles behind Moberly Area Community College and San Jacinto College - Central, which each have four titles. 3 NJCAA National Championships; 1965, 1970, 1972 National Finalist in 1986 National Semi-Finalist in 1974, 1983, 1992, 1993 National Tournament Top 10 finishes: 1967, 1968, 1969, 1973, 1975, 1977, 1988, 1989, 1995, 1997, 1998 and 2000 30 appearances in the NJCAA National Tournament 28 appearances in the NJCAA finals. 34 NJCAA Region 12 championships. 9 NJCAA District 12 championships. 7 Inter-region playoffs Professional Hysteria Indiana Pacers The Indiana Pacers are a professional basketball team that plays in the National Basketball Association (NBA).

The team is the sister team of the NBA's Indiana Pacers. Founded in 2000 Home-Conseco Fieldhouse Tamika Catchings Mascot-Freddy Fever National Hysteria Big Ten Tournament At the conclusion of the regular Big Ten season, a tournament is held to determine the conference winner, who receives the conference's automatic bid to the NCAA tournament. Indianapolis has played host for the men's tournament on three occasions to date. Indianapolis has hosted all but one of the women's tournaments since its inception in 1995. Beginning in 2008, the Big Ten Conference Men's Basketball Tournament will be held exclusively at Indianapolis' Conseco Fieldhouse. Final Four Indianapolis, Indiana, often referred to as the "Amateur Sports Capital of the World" has hosted a number of collegiate basketball events. Aside from the multitude of regional games held during the NCAA tournament, Indianapolis has hosted five men's NCAA Final Fours (1980, 1991, 1997, 2000, 2006) and one women's (2005). Indianapolis is scheduled to host the men's 2010 and 2015 Final Fours as well as the women's in 2011. Previous events were held in the Market Square Arena or the RCA Dome, but given the new stadium being built for the Indianapolis Colts, Lucas Oil Stadium will host future events. When the NCAA Headquarters relocated to Indianapolis, it was stated that Indianapolis would then host the men's Final Four once every five years. The leading factor in the NCAA's decision to move to Indianapolis was the overwhelming amount of local athletic infrastructure, all of it world-class. World Championships In 2002, Indianapolis hosted the FIBA World Championship, an event that takes place on even years opposite the Olympic Games. Since inaugural event in 1950, Indianapolis is the only city in the United States to have hosted the event.

7,793 | Icon_(programming_language) | Icon is a very high-level programming language featuring goal directed execution and many facilities for managing strings and textual patterns. It is related to SNOBOL, a string processing language. Icon is not object-oriented, but an object-oriented extension called Idol was developed in 1996 which eventually became Unicon. Basic syntax The Icon language is derived from the ALGOL-class of structured programming languages, and thus has syntax similar to C or Pascal. Icon is most similar to Pascal, using := syntax for assignments, the procedure keyword and similar syntax. On the other hand, Icon uses C-style brackets for structuring execution groups, and programs start by running a procedure called "main". In many ways Icon also shares features with most scripting programming languages (as well as Snobol from which they were taken): variables do not have to be declared, types are cast automatically, and numbers can be converted to strings and back automatically. Another feature common to many scripting languages, but not all, is the lack of a line-ending character; in Icon, lines not ended by a semicolon get ended by an implied semicolon if it makes sense. Procedures are the basic building blocks of Icon programs, and although they use Pascal naming they work more like C functions and can return values; there is no function keyword in Icon. procedure doSomething(aString) write(aString) end Goal-directed execution One of Icon's key concepts is that control structures are based on the "success" or "failure" of expressions, rather than on boolean logic, as in most other programming languages. Under this model, simple comparisons like if a < b do not mean "if the operations to the right evaluate to true" as they would under most languages; instead it means something more like "if the operations to the right succeed". In this case the < operator succeeds if the comparison is true, so the end result is the same. In addition, the < operator returns its second argument if it succeeds, allowing things like if a < b < c, a common type of comparison that cannot be directly stated in most languages. The utility of this concept becomes much clearer when you consider real-world examples. Since Icon uses success or failure for all flow control, this simple code: if a := read() then write(a) Will copy one line of the standard input to standard output. What's interesting about this example is that the code will work even if the read() causes an error, for instance, if the file does not exist. In that case the statement a := read() will fail, and write will simply not be called. Success and failure are passed "up" through functions, meaning that a failure inside a nested function will cause the functions calling it to fail as well. For instance, we can write a program to copy an entire input file to output in a single line: while write(read()) When the read() command fails, at the end of file for instance, the failure will be passed up the chain and write() will fail as well. The while, being a control structure, stops on failure, meaning it stops when the file is empty. For comparison, consider a similar example written in Java-based pseudocode: try { while ((a = read()) != EOF) { write(a); } } catch (Exception e) { // do nothing, exit the loop } In this case there are two comparisons needed, one for end of file (EOF) and another for all other errors. Since Java does not allow errors to be compared as logic elements, as under Icon, the lengthy try/catch syntax must be used instead. Try blocks also impose a performance penalty for simply using them, even if no error occurs, a distributed cost that Icon avoids. Icon refers to this concept as goal-directed execution, referring to the way that execution continues until some goal is reached. In the example above the goal is to read the entire file; the read command continues to succeed while there is more information to be read, and fails when there isn't. The goal is thus coded directly in the language, instead of using statements checking return codes or similar constructs. Generators Expressions in Icon often return a single value, for instance, x < 5 will evaluate and succeed with the value 5 or fail. However several of the examples below rely on the fact that many expressions do not immediately return success or failure, returning values in the meantime. This drives the examples with every and to; every causes to to continue to return values until it fails. This is a key concept in Icon, known as generators. Generators drive much of the loop functionality in the language, but do so more directly; the programmer does not write a loop and then pull out and compare values, Icon will do all of this for you. Within the parlance of Icon, the evaluation of an expression or function results in a result sequence. A result sequence contains all the possible values that can be generated by the expression or function. When the result sequence is exhausted (e.g. there are no more values within the result sequence), the expression or function fails. Iteration over the result sequence is achieved either explicitly via Icon's goal directed evaluation or explicitly via the every clause. Icon includes several generator-builders. The alternator syntax allows a series of items to be generated in sequence until one fails: 1 | "hello" | x < 5 can generate "1", "hello", and "5" if x is less than 5. Alternators can be read as "or" in many cases, for instance: if y < (x | 5) then write("y=", y) will write out the value of y if it is smaller than x or 5. Internally Icon checks every value from left to right until one succeeds or the list empties and it returns a failure. Remember that functions will not be called unless the calls within do not fail, so this example can be shortened to: write("y=", (x | 5) > y) Another simple generator is the to, which generates lists of integers; every write(1 to 10) will do exactly what it seems to. The bang syntax generates every item of a list; every write(!aString) will output each character of aString on a new line. To demonstrate the power of this concept, consider string operations. Most languages include a function known as find or indexOf that returns the location of a string within another. Consider: s = "All the world's a stage. And all the men and women merely players"; i = indexOf("the", s) This code will return 4, the position of the first occurrence of the word "the". To get the next instance of "the" an alternate form must be used, i = indexOf("the", s, 5) the 5 at the end saying it should look from position 5 on. In order to extract all the occurrences of "the", a loop must be used... s = "All the world's a stage. And all the men and women merely players"; i = indexOf("the", s) while i != -1 { write(i); i = indexOf("the", s, i+1); } Under Icon the find function is a generator, and will return the next instance of the string each time it is resumed before finally failing after it passes the end of the string. The same code under Icon can be written: s := "All the world's a stage. And all the men and women merely players" every write(find("the",s)) find will return the index of the next instance of "the" each time it is resumed by every, eventually passing the end of the string and failing. As in the prior example, this will cause write to fail, and the (one-line) every loop to exit. Of course there are times where you deliberately want to find a string after some point in input, for instance, you might be scanning a text file containing data in multiple columns. Goal-directed execution works here as well, and can be used this way: write(5 < find("the", s)) The position will only be returned if "the" appears after position 5, the comparison will fail otherwise, passing that failure to write() as before. There is one small "trick" to this code that needs to be considered: comparisons return the right hand result, so it is important to put the find on the right hand side of the comparison. If the 5 were placed on the right, 5 would be written. Icon adds several control structures for looping through generators. The every operator is similar to while, looping through every item returned by a generator and exiting on failure: every k := i to j do write(someFunction(k)) Why use every instead of a while loop in this case? Because while re-evaluates the first result, but every produces all results. The every syntax actually injects values into the function in a fashion similar to blocks under Smalltalk. For instance, the above loop can be re-written this way: every write(someFunction(i to j)) Users can build new generators easily using the suspend keyword: procedure findOnlyOdd(pattern, theString) every i := find(pattern, theString) do if i % 2 = 1 then suspend i end This example loops over theString using find to look for pattern. When one is found, and the position is even, the location is returned from the function with suspend. Unlike return, suspend writes down where it is in the internal generators as well, allowing it to pick up where it left off on the next iteration. Strings In keeping with its script-like functionality, Icon adds a number of features to make working with strings easier. Most notable among these is the scanning system, which repeatedly calls functions on a string: s ? write(find("the")) is a short form of the examples shown earlier. In this case the subject of the find function is placed outside the parameters in front of the question-mark. Icon functions are deliberately (as opposed to automatically) written to identify the subject in parameter lists and allow them to be pulled out in this fashion. Substrings can be extracted from a string by using a range specification within brackets. A range specification can return a point to a single character, or a slice of the string. Strings can be indexed from either the right or the left. It is important to note that positions within a string are between the characters 1A2B3C4 and can be specified from the right -3A-2B-1C0 For example "Wikipedia"[1] ==> "W" "Wikipedia"[3] ==> "k" "Wikipedia"[0] ==> "a" "Wikipedia"[1:3] ==> "Wi" "Wikipedia"[-2:0] ==> "ia" "Wikipedia"[2+:3] ==> "iki" Where the last example shows using a length instead of an ending position The subscripting specification can be used as a Lvalue within an expression. This can be used to insert strings into another string or delete parts of a string. For example, s := "abc" s[2] := "123" s now has a value of "a123c" s := "abcdefg" s[3:5] := "ABCD" s now has a value of "abABCDefg" s := "abcdefg" s[3:5] := "" s now has a value of "abefg" Other structures Icon also allows the user to easily construct their own lists (or arrays): aCat := ["muffins", "tabby", 2002, 8] The items within a list can be of any sort, including other structures. To quickly build larger lists, Icon includes the list generator; i := list(10, "word") generates a list containing 10 copies of "word". Like arrays in other languages, Icon allows items to be looked up by position, e.g., weight := aCat[4]. The bang-syntax, e.g., every write(!aCat), will print out four lines, each with one element. Icon includes stack-like functions, push and pop to allow them to form the basis of stacks and queues. Icon also includes functionality for sets and tables (known as hashes, associative arrays, dictionaries, etc.): symbols := table(0) symbols["there"] := 1 symbols["here"] := 2 This code creates a table that will use zero as the default value of any unknown key. It then adds two items into it, with the keys "there" and "here", and values 1 and 2. String scanning One of the powerful features of Icon is string scanning. The scan string operator, ? saves the current string scanning environment and creates a new string scanning environment. The string scanning environment consists of two keyword variables, &subject and &pos. Where &subject is the string being scanned, and &pos is the cursor or current position within the subject string. For example s := "this is a string" s ? write("subject=[",&subject,"] pos=[",&pos,"]") would produce subject=[this is a string] pos=[1] Built-in and user defined functions can be used to move around within the string being scanned. Many of the built in functions will default to &subject and &pos (for example the find function). The following, for example, will write all blank delimited "words" in a string. s := "this is a string" s ? { # Establish string scanning environment while not pos(0) do { # Test for end of string tab(many(' ')) # Skip past any blanks word := tab(upto(' ') | 0) # the next word is up to the next blank -or- the end of the line write(word) # write the word } } A more complicated example demonstrates the integration of generators and string scanning within the language. procedure main() s := "Mon Dec 8" s ? write(Mdate() | "not a valid date") end # Define a matching function that returns # a string that matches a day month dayofmonth procedure Mdate() # Define some initial values static dates static days initial { days := ["Mon","Tue","Wed","Thr","Fri","Sat","Sun"] dates := ["Jan","Feb","Mar","Apr","May","Jun", "Jul","Aug","Sep","Oct","Nov","Dec"] } every suspend (retval <- tab(match(!days)) || # Match a day =" " || # Followed by a blank tab(match(!dates)) || # Followed by the month =" " || # Followed by a blank matchdigits(2) # Followed by at least 2 digits ) & (=" " | pos(0) ) & # Either a blank or the end of the string retval # And finally return the string end # Matching function that returns a string of n digits procedure matchdigits(n) suspend (v := tab(many(&digits)) & *v <= n) & v end The idiom of expr1 & expr2 & expr3 returns the value of the last expression References The definitive work is The Icon Programming Language (third edition) by Griswold and Griswold, ISBN 1-57398-001-3.

7,794 | Miranda_Richardson | Miranda Jane Richardson (born 3 March 1958) is an Academy Award-nominated and Golden Globe-winning English stage, film and television actress. Early life Richardson was born and raised in Southport, (then part of Lancashire now in Merseyside), England to Marian Georgina (née Townsend), a housewife, and William Alan Richardson, a marketing executive. Miranda Richardson Biography (1958-) The second daughter in a middle-class family, she revealed a talent for acting from an early age. She had originally intended to study veterinary medicine, but her squeamishness made this impractical. Career Theatre Richardson enrolled at the Bristol Old Vic Theatre School http://www.oldvic.ac.uk/past_graduates.html Bristol Old Vic Theatre School, Past Graduates , where she studied alongside Daniel Day-Lewis. In 1981, she made her stage debut in Moving at the Queen's Theatre in London. Before making a name for herself as a screen star, she enjoyed a hugely successful and extensive theatre career. Starting out with juvenile performances in Cinderella (the title role) and Lord Arthur Saville's Crime (as Sybil Merton) at the Southport Dramatic Club, the young thespian enrolled at the Bristol Old Vic Theatre School, making her stage debut in Moving at the Queen's Theatre, London. Soon afterwards, she appeared in repertory theatre, until she found recognition in the West End for a series of highly praised stage performances, ultimately receiving an Olivier Award nomination for her performance in A Lie of the Mind The Society of London Theatre, Olivier Winners 1987 , and in 1996 being cited as 'the greatest actress of our time in any medium' by one critic after she appeared in Orlando at the Edinburgh Festival. Richardson will return to the London stage for the first time in ten years, to play the lead in Wallace Shawn's new play, Grasses of a Thousand Colours at the Royal Court Theatre in May 2009. Royal Court Theatre website Film and television In 1985, Richardson made her film debut as platinum blonde nightclub hostess Ruth Ellis, the last woman to be hanged in the United Kingdom in Mike Newell's critically acclaimed biographical drama, Dance With A Stranger. Her performance won her much praise, and within a year she had been cast by Steven Spielberg to appear in his World War II drama, Empire of the Sun (1987). Richardson is well-known for her role as an infantile Queen Elizabeth I, aka Queenie, in the British television comedy Blackadder II (1986). She returned to that role for a Christmas special (Blackadder's Christmas Carol 1988) and a special edition for the millennium (Blackadder: Back and Forth, 2000). Her portrayal of a troubled theatre-goer in Secret Friends (BBC 2 TV, 1990) was described as "a miniature tour de force... Miranda Richardson's finest hour, all in ten minutes" (The Sunday Times). Other television roles include the bitchy Pamela Flitton in A Dance to the Music of Time (1997), Miss Gilchrist in St. Ives (1998), Bettina the obsessive-compulsive interior decorator in Absolutely Fabulous, the sadistic Queen Elspeth in Hallmark's Snow White: The Fairest Of Them All (2001), and the emotionally repressed Queen Mary in The Lost Prince (2003). Richardson has appeared in a number of high-profile supporting roles in the cinema, including Vanessa Bell in The Hours, Lady Van Tassel in Sleepy Hollow and Patsy Carpenter in The Evening Star. She also won acclaim for [her performances in The Crying Game and Enchanted April, for which she won a Golden Globe, beating a quartet of Hollywood heavyweights: Geena Davis, Whoopi Goldberg, Shirley MacLaine and Meryl Streep. She received Academy Award nominations for her performances in Damage and Tom & Viv. Her extensive film credits include stints in a number of critically acclaimed independent features, among them Robert Altman's Kansas City (1996), Robert Duvall's The Apostle (1997) and Richard E. Grant's Wah-Wah (2005). In 2002, she performed a triple-role stint alongside Ralph Fiennes in David Cronenberg's acclaimed thriller Spider, a film that won her several international critics awards. Richardson also appeared as Queen Rosalind of Denmark in the Julia Stiles vehicle The Prince and Me and as the ballet mistress Madame Giry in the long-awaited film version of The Phantom Of The Opera, starring Gerard Butler and Emmy Rossum. In 2005 she appeared in the high-profile role of Rita Skeeter, the toxic Daily Prophet journalist in Harry Potter And The Goblet Of Fire and has since appeared in a number of critically acclaimed but low-profile feature films. In 2006 she appeared alongside Bill Nighy in Stephen Poliakoff's multi-Golden Globe winning BBC drama, Gideon's Daughter. She played the role of Mrs. Claus in the film Fred Claus (2007), co-starring Vince Vaughn and Paul Giamatti. Richardson teamed up alongside Absolutely Fabulous star Jennifer Saunders in the BBC sitcom, The Life and Times of Vivienne Vyle. She appeared as a guest on Nigel Slater's A Taste of my Life in which she cooked dishes including lamb tagine and huevos rancheros. It was announced in December 2008 that Richardson was cast in a leading role in original AMC pilot, Rubicon. She will reportedly play a New York socialite who finds herself drawn into the central intrigue of a think tank, after the death of her husband. Hollywood Reporter article Additionally, the actress will play notorious Labour politician Barbara Castle in the upcoming British film We Want Sex. Personal life Currently, Richardson lives in West London with her two cats, Otis and Waldo, and her dog, Liv.

7,795 | Aegean_civilizations | Aegean civilization is a general term for the Bronze Age civilizations of Greece and the Aegean. There are in fact three distinct but communicating and interacting geographic regions covered by this term: Crete, the Cyclades and the Greek mainland. Crete is associated with the Minoan civilization from the Early Bronze Age, while the Cyclades and the mainland have distinct cultures. The Cyclades converge with the mainland during the Early Helladic ("Minyan") period and with Crete in the Middle Minoan period. From ca. 1450 (Late Helladic, Late Minoan), the Greek Mycenaean civilization spreads to Crete. Periodization Mainland Early Helladic EH 2800-2100 BCE Middle Helladic MH 2100-1500 BCE Late Helladic LH 1500-1100 BCE Crete Early Minoan EM 3650-2160 BCE Middle Minoan MM 2160-1600 BCE Late Minoan LM 1600-1170 BCE Cyclades Early Cycladic 3300-2000 BCE Kastri = EH II-EH III (ca. 2500-2100) BCE Convergence with MM from ca. 2000 BCE Commerce Commerce was practised to some extent in very early times, as is proved by the distribution of Melian obsidian over all the Aegean area. We find Cretan vessels exported to Melos, Egypt and the Greek mainland. Melian vases came in their turn to Crete. After 1600 B.C. there is very close commerce with Egypt, and Aegean things find their way to all coasts of the Mediterranean. No traces of currency have come to light, unless certain axeheads, too slight for practical use, had that character. Standard weights have been found, as well as representations of ingots. The Aegean written documents have not yet proved (by being found outside the area) to be epistolary (letter writing) correspondence with other countries. Representations of ships are not common, but several have been observed on Aegean gems, gem-sealings, frying pans and vases. They are vessels of low free-board, with masts and oars. Familiarity with the sea is proved by the free use of marine motifs in decoration. The most detailed illustrations are to be found on the 'ship fresco' at Akrotiri on the island of Thera (Santorini) preserved by the ash fall from the volcanic eruption which destroyed the town there. Discoveries, later in the twentieth century, of sunken trading vessels such as those at Uluburun and Cape Gelidonya off the south coast of Turkey have brought forth an enormous amount of new information about that culture. Evidence For details of monumental evidence the articles on Crete, Mycenae, Tiryns, Troad, Cyprus, etc., must be consulted. The most representative site explored up to now is Knossos (see Crete) which has yielded not only the most various but the most continuous evidence from the Neolithic age to the twilight of classical civilization. Next in importance come Hissarlik, Mycenae, Phaestus, Hagia Triada, Tiryns, Phylakope, Palaikastro and Gournia. Internal evidence Structures; Ruins of palaces, palatial villas, houses, built dome- or cist-graves and fortifications (Aegean islands, Greek mainland and northwestern Anatolia), but not distinct temples; small shrines, however, and temene (religious enclosures, remains of one of which were probably found at Petsofa near Palaikastro by J. L. Myres in 1904) are represented on intaglios and frescoes. From the sources and from inlay-work we have also representations of palaces and houses. Structural Decoration; Architectural features, such as columns, friezes and various mouldings; mural decoration, such as fresco-paintings, coloured reliefs and mosaic inlay. Roof tiles were also occasionally employed, as at early Helladic Lerna and Akovitika, Joseph W. Shaw, The Early Helladic II Corridor House: Development and Form, American Journal of Archaeology, Vol. 91, No. 1. (Jan., 1987), pp. 59-79 (72). and later in the Mycenaean towns of Gla and Midea. Ione Mylonas Shear, “Excavations on the Acropolis of Midea: Results of the Greek-Swedish Excavations under the Direction of Katie Demakopoulou and Paul åström”, American Journal of Archaeology, Vol. 104, No. 1. (Jan., 2000), pp. 133-134. Furniture; (a) Domestic furniture, such as vessels of all sorts and in many materials, from huge store jars down to tiny unguent pots; culinary and other implements; thrones, seats, tables, etc., these all in stone or plastered terracotta. (b) Sacred furniture, such as models or actual examples of ritual objects; of these we have also numerous pictorial representations. (c) Funerary furniture, e.g. coffins in painted terracotta. Art products; E.g. plastic objects, carved in stone or ivory, cast or beaten in metals (gold, silver, copper and bronze), or modelled in clay, faience, paste, etc. Very little trace has yet been found of large free-standing sculpture, but many examples exist of sculptors' smaller work. Vases of all kinds, carved in marble or other stones, cast or beaten in metals or fashioned in clay, the latter in enormous number and variety, richly ornamented with coloured schemes, and sometimes bearing moulded decoration. Examples of painting on stone, opaque and transparent. Engraved objects in great number e.g. ring-bezels and gems; and an immense quantity of clay impressions, taken from these. Weapons, tools and implements; In stone, clay and bronze, and at the last iron, sometimes richly ornamented or inlaid. Numerous representations also of the same. No actual body-armour, except such as was ceremonial and buried with the dead, like the gold breastplates in the circle-graves at Mycenae or the full length body armour from Dendra. Articles of personal use; E.g. brooches (fibulae), pins, razors, tweezers, etc., often found as dedications to a deity, e.g. in the Dictaean Cavern of Crete. No textiles have survived other than impressions in clay. Written documents; E.g. clay tablets and discs (so far in Crete only), but nothing of more perishable nature, such as skin, papyrus, etc.; engraved gems and gem impressions; legends written with pigment on pottery (rare); characters incised on stone or pottery. These show a number of systems of script employing either ideograms or syllabograms (see Linear B). Excavated tombs; Of either the pit, chamber or the tholos kind, in which the dead were laid, together with various objects of use and luxury, without cremation, and in either coffins or loculi or simple wrappings. Public works; Such as paved and stepped roadways, bridges, systems of drainage, etc. External evidence Monuments and records of other contemporary civilizations; E.g. representations of alien peoples in Egyptian frescoes; imitation of Aegean fabrics and style in non-Aegean lands; allusions to Mediterranean peoples in Egyptian, Semitic or Babylonian records. Literary traditions of subsequent civilizations; Especially the Hellenic; such as, e.g., those embodied in the Homeric poems, the legends concerning Crete, Mycenae, etc.; statements as to the origin of gods, cults and so forth, transmitted to us by Hellenic antiquarians such as Strabo, Pausanias, Diodorus Siculus, etc. Traces of customs, creeds, rituals, etc; In the Aegean area at a later time, discordant with the civilization in which they were practised and indicating survival from earlier systems. There are also possible linguistic and even physical survivals to be considered. Mycenae and Tiryns are the two principal sites on which evidence of a prehistoric civilization was remarked long ago by the classical Greeks. Discovery The curtain-wall and towers of the Mycenaean citadel, its gate with heraldic lions, and the great "Treasury of Atreus" had borne silent witness for ages before Heinrich Schliemann's time; but they were supposed only to speak to the Homeric, or, at farthest, a rude Heroic beginning of purely Hellenic civilization. It was not until Schliemann exposed the contents of the graves which lay just inside the gate, that scholars recognized the advanced stage of art which prehistoric dwellers in the Mycenaean citadel had attained. There had been, however, a good deal of other evidence available before 1876, which, had it been collated and seriously studied, might have discounted the sensation that the discovery of the citadel graves eventually made. Although it was recognized that certain tributaries, represented e.g. in the XVIIIth Dynasty tomb of Rekhmara at Egyptian Thebes as bearing vases of peculiar forms, were of some Mediterranean race, neither their precise habitat nor the degree of their civilization could be determined while so few actual prehistoric remains were known in the Mediterranean lands. Nor did the Aegean objects which were lying obscurely in museums in 1870, or thereabouts, provide a sufficient test of the real basis underlying the Hellenic myths of the Argolid, the Troad and Crete, to cause these to be taken seriously. Aegean vases have been exhibited both at Sèvres and Neuchatel since about 1840, the provenience (i.e. source or origin) being in the one case Phylakope in Melos, in the other Cephalonia. Ludwig Ross, the German archaeologist appointed Curator of the Antiquities of Athens at the time of the establishment of the Kingdom of Greece, by his explorations in the Greek islands from 1835 onwards, called attention to certain early intaglios, since known as Inselsteine; but it was not until 1878 that C. T. Newton demonstrated these to be no strayed Phoenician products. In 1866 primitive structures were discovered on the island of Therasia by quarrymen extracting pozzolana, a siliceous volcanic ash, for the Suez Canal works. When this discovery was followed up in 1870, on the neighbouring Santorin (Thera), by representatives of the French School at Athens, much pottery of a class now known immediately to precede the typical late Aegean ware, and many stone and metal objects, were found. These were dated by the geologist Ferdinand A. Fouqué, somewhat arbitrarily, to 2000 B.C., by consideration of the superincumbent eruptive stratum. Meanwhile, in 1868, tombs at Ialysus in Rhodes had yielded to Alfred Biliotti many fine painted vases of styles which were called later the third and fourth "Mycenaean"; but these, bought by John Ruskin, and presented to the British Museum, excited less attention than they deserved, being supposed to be of some local Asiatic fabric of uncertain date. Nor was a connection immediately detected between them and the objects found four years later in a tomb at Menidi in Attica and a rock-cut "bee-hive" grave near the Argive Heraeum. Even Schliemann's first excavations at Hissarlik in the Troad did not excite surprise. But the "Burnt City" of his second stratum, revealed in 1873, with its fortifications and vases, and a hoard of gold, silver and bronze objects, which the discoverer connected with it, began to arouse a curiosity which was destined presently to spread far outside the narrow circle of scholars. As soon as Schliemann came on the Mycenae graves three years later, light poured from all sides on the prehistoric period of Greece. It was recognized that the character of both the fabric and the decoration of the Mycenaean objects was not that of any well-known art. A wide range in space was proved by the identification of the Inselsteine and the Ialysus vases with the new style, and a wide range in time by collation of the earlier Theraean and Hissarlik discoveries. A relationship between objects of art described by Homer and the Mycenaean treasure was generally allowed, and a correct opinion prevailed that, while certainly posterior, the civilization of the Iliad was reminiscent of the Mycenaean. Schliemann got to work again at Hissarlik in 1878, and greatly increased our knowledge of the lower strata, but did not recognize the Aegean remains in his "Lydian" city of the sixth stratum. These were not to be fully revealed until Dr. Wilhelm Dorpfeld, who had become Schliemann's assistant in 1879, resumed the work at Hissarlik in 1892 after the first explorer's death. But by laying bare in 1884 the upper stratum of remains on the rock of Tiryns, Schliemann made a contribution to our knowledge of prehistoric domestic life which was amplified two years later by Christos Tsountas's discovery of the palace at Mycenae. Schliemann's work at Tiryns was not resumed till 1905, when it was proved, as had long been suspected, that an earlier palace underlies the one he had exposed. From 1886 dates the finding of Mycenaean sepulchres outside the Argolid, from which, and from the continuation of Tsountas's exploration of the buildings and lesser graves at Mycenae, a large treasure, independent of Schliemann's princely gift, has been gathered into the National Museum at Athens. In that year tholos-tombs, most already pillaged but retaining some of their furniture, were excavated at Arkina and Eleusis in Attica, at Dimini near Volos in Thessaly, at Kampos on the west of Mount Taygetus, and at Maskarata in Cephalonia. The richest grave of all was explored at Vaphio in Laconia in 1889, and yielded, besides many gems and miscellaneous goldsmiths' work, two golden goblets chased with scenes of bull-hunting, and certain broken vases painted in a large bold style which remained an enigma until the excavation of Cnossus. In 1890 and 1893, Staes cleared out certain less rich tholos-tombs at Thoricus in Attica; and other graves, either rock-cut "bee-hives" or chambers, were found at Spata and Aphidna in Attica, in Aegina and Salamis, at the Argive Heraeum and Nauplia in the Argolid, near Thebes and Delphi, and not far from the Thessalian Larissa. During the Acropolis excavations in Athens, which terminated in 1888, many potsherds of the Mycenaean style were found; but Olympia had yielded either none, or such as had not been recognized before being thrown away, and the temple site at Delphi produced nothing distinctively Aegean (in dating). The American explorations of the Argive Heraeum, concluded in 1895, also failed to prove that site to have been important in the prehistoric time, though, as was to be expected from its neighbourhood to Mycenae itself, there were traces of occupation in the later Aegean periods. Prehistoric research had now begun to extend beyond the Greek mainland. Certain central Aegean islands, Antiparos, Ios, Amorgos, Syros and Siphnos, were all found to be singularly rich in evidence of the Middle-Aegean period. The series of Syran-built graves, containing crouching corpses, is the best and most representative that is known in the Aegean. Melos, long marked as a source of early objects but not systematically excavated until taken in hand by the British School at Athens in 1896, yielded at Phylakope remains of all the Aegean periods, except the Neolithic. A map of Cyprus in the later Bronze Age (such as is given by J. L. Myres and M. O. Richter in Catalogue of the Cyprus Museum) shows more than twenty-five settlements in and about the Mesaorea district alone, of which one, that at Enkomi, near the site of Salamis, has yielded the richest Aegean treasure in precious metal found outside Mycenae. E. Chantre in 1894 picked up lustreless ware, like that of Hissariik, in central Phtygia and at Pteria, and the English archaeological expeditions, sent subsequently into north-western Anatolia, have never failed to bring back ceramic specimens of Aegean appearance from the valleys of the Rhyndncus, Sangarius and Halys. In Egypt in 1887, W. M. F. Petrie found painted sherds of Cretan style at Kahun in the Fayum, and farther up the Nile, at Tell el-Amarna, chanced on bits of no fewer than 800 Aegean vases in 1889. There have now been recognized in the collections at Cairo, Florence, London, Paris and Bologna several Egyptian imitations of the Aegean style which can be set off against the many debts which the centres of Aegean culture owed to Egypt. Two Aegean vases were found at Sidon in 1885, and many fragments of Aegean and especially Cypriote pottery have been turned up during recent excavations of sites in Philistia by the Palestine Fund. Sicily, ever since P. Orsi excavated the Sicel cemetery near Lentini in 1877, has proved a mine of early remains, among which appear in regular succession Aegean fabrics and motives of decoration from the period of the second stratum at Hissarlik. Sardinia has Aegean sites, e.g. at Abini near Teti; and Spain has yielded objects recognized as Aegean from tombs near Cadiz and from Saragossa. One land, however, has eclipsed all others in the Aegean by the wealth of its remains of all the prehistoric ages— Crete; and so much so that, for the present, we must regard it as the fountainhead of Aegean civilization, and probably for long its political and social centre. The island first attracted the notice of archaeologists by the remarkable archaic Greek bronzes found in a cave on Mount Ida in 1885, as well as by epigraphic monuments such as the famous law of Gortyna. But the first undoubted Aegean remains reported from it were a few objects extracted from Cnossus by Minos Kalokhairinos of Candia in 1878. These were followed by certain discoveries made in the S. plain Messara by F. Halbherr. Unsuccessful attempts at Cnossus were made by both W. J. Stillman and H. Schliemann, and A. J. Evans, coming on the scene in 1893, travelled in succeeding years about the island picking up trifles of unconsidered evidence, which gradually convinced him that greater things would eventually be found. He obtained enough to enable him to forecast the discovery of written characters, till then not suspected in Aegean civilization. The revolution of 1897-98 opened the door to wider knowledge, and much exploration has ensued, for which see Crete. Thus the "Aegean Area" has now come to mean the Archipelago with Crete and Cyprus, the Hellenic peninsula with the Ionian islands, and Western Anatolia. Evidence is still wanting for the Macedonian and Thracian coasts. Offshoots are found in the western Mediterranean area, in Sicily, Italy, Sardinia and Spain, and in the eastern Mediterranean area in Syria and Egypt. Regarding the Cyrenaica, we are still insufficiently informed. References See also Minoan civilization Mycenaean Greece Aegean Sea Prehistoric Balkans External links Jeremy B.

7,796 | Creaky_voice | In linguistics, creaky voice (sometimes called laryngealisation, pulse phonation or, vocal fry or glottal fry), is a special kind of phonation Titze, I. R. (2008). The human instrument. Sci.Am. 298 (1):94-101. PM 18225701 Titze, I.R. (1994). Principles of Voice Production, Prentice Hall, ISBN 978-0137178933. in which the arytenoid cartilages in the larynx are drawn together; as a result, the vocal folds are compressed rather tightly, becoming relatively slack and compact. They vibrate irregularly at 20–50 pulses per second, about two octaves below the frequency of normal voicing, and the airflow through the glottis is very slow. However, although creaky voice may occur with very low pitch, as at the end of a long intonation unit, it can occur with any pitch. A slight degree of laryngealisation, occurring e.g. in some Korean consonants is called "stiff voice". The Danish prosodic feature stød is an example of a form of laryngealisation that has a phonemic function. Creaky voice manifests itself in the idiolects of some American English speakers, particularly at the beginnings of sentences that the speaker wishes to "soft-pedal" . Although this phenomenon is in general more prominent among female American English speakers than among male speakers, it is frequently adopted by older males in leadership positions in business and politics . It can also occur accidentally when the speaker's throat is tired, or if the speaker is sick, and tries to reach very high notes.

7,797 | Max_August_Zorn | Max August Zorn (June 6, 1906 in Krefeld, Germany – March 9, 1993 in Bloomington, Indiana, United States) was a German-born American mathematician. He was an algebraist, group theorist, and numerical analyst. He is famous for Zorn's lemma, a powerful tool in set theory that is applicable to a wide range of mathematical constructs such as vector spaces, ordered sets, etc. Zorn's lemma was first discovered by K. Kuratowski in 1922, and then independently by Zorn in 1935. He was a professor at Indiana University from 1946 until his death. According to Indiana University math professor Kent Orr, a traffic light was installed near the math building on account of Zorn nearly being killed by a car as an elderly professor emeritus. Zorn was also an avid guitar player; there is a picture of him playing guitar hanging in Rawles Hall, where Bloomington's math faculty resides. Max Zorn married Alice Schlottau and they had one son, Jens, and one daughter, Liz. Zorn's grandson Eric Zorn is a columnist for the Chicago Tribune.

7,798 | Cyanide | The cyanide ion, CN−. From the top: 1. Valence-bond structure 2. Space-filling model 3. Electrostatic potential surface 4. 'Carbon lone pair' HOMO A cyanide is any chemical compound that contains the cyano group (C≡N), which consists of a carbon atom triple-bonded to a nitrogen atom. Inorganic cyanides are hydrogen cyanide salts in which cyanide is generally the anion CN-. Organic compounds that have a -C≡N functional group bonded to an alkyl residue are called nitriles in IUPAC nomenclature. The cyanide radical CN is commonly produced in reactions and has been identified in interstellar space. Of the many kinds of cyanide compounds, some are gases; others are solids or liquids. Those that can release the cyanide ion CN- are highly toxic. An example of a nitrile is CH3CN, acetonitrile or ethanenitrile per IUPAC, also known as methyl cyanide. Nitriles do not release cyanide ions. A functional group with a hydroxyl and cyanide on the same carbon is called cyanohydrin, and it is hydrolyzed into hydrogen cyanide and a carbonyl compound (ketone or aldehyde). Etymology The word "cyanide" was extracted from "ferrocyanide", which proved to be a compound of iron and what is now known as the cyanide ion. Ferrocyanides and ferricyanides were first discovered as Prussian blue, and were so named because Prussian blue contains iron and is blue; kyaneos is Greek for "(dark) blue". Appearance and odor Hydrogen cyanide (HCN) is a colorless gas with a faint bitter-almond-like odor. Most people can smell hydrogen cyanide; however, due to an apparent genetic trait, some individuals cannot. Online Mendelian Inheritance in Man, Cyanide, inability to smell Sodium cyanide and potassium cyanide are both white powders with a bitter-almond-like odor in damp air, due to the presence of hydrogen cyanide formed by hydrolysis: NaCN + H2O → HCN + NaOH KCN + H2O → HCN + KOH Occurrence Cyanides are produced by certain bacteria, fungi, and algae and are found in a number of foods and plants. Cyanides are found, although in small amounts, in apple seeds, mango stones, peach stones and bitter almonds. In plants, cyanides are usually bound to sugar molecules in the form of cyanogenic glycosides and defend the plant against herbivores. Cassava roots (also called manioc), an important potato-like food grown in tropical countries (and the base from which tapioca is made), also contain cyanogenic glycosides. The Fe-only and [NiFe]-hydrogenase enzymes contain cyanide ligands at their active sites. The biosynthesis of cyanide in the [NiFe]-hydrogenases proceeds from carbamoylphosphate, which converts to cysteinyl thiocyanate, the CN- donor. Hydrogen cyanide is a product of certain kinds of pyrolysis and consequently it occurs in the exhaust of internal combustion engines, tobacco smoke, and certain plastics, especially those derived from acrylonitrile. Coordination chemistry The cyanide anion is considered, in a broad sense, to be the most potent ligand for many transition metals. The very high affinities of metals for this anion can be attributed to its negative charge, compactness, and ability to engage in π-bonding. Well known complexes include: hexacyanides [M(CN)6]3− (M = Ti, V, Cr, Mn, Fe, Co), which are octahedral in shape; the tetracyanides, [M(CN)4]2− (M = Ni, Pd, Pt), which are square planar in their geometry; the dicyanides [M(CN)2]− (M = Cu, Ag, Au), which are linear in geometry. The deep blue pigment Prussian blue, used in the making of blueprints, is derived from iron cyanide complexes (hence the name cyanide, from cyan, a shade of blue). Prussian blue can produce hydrogen cyanide when exposed to acids. Organic derivatives Because of the cyanide anion's high nucleophilicity, a cyano group is readily introduced into organic molecules by displacement of a halide group (i.e. the chloride on methyl chloride). Organic cyanides are generally called nitriles. Thus, CH3CN can be methyl cyanide but more commonly is referred to as acetonitrile. In organic synthesis, cyanide is used as a C-1 synthon. I.e., it can be used to lengthen a carbon chain by one, while retaining the ability to be functionalized. RX + CN− → RCN + X− (Nucleophilic Substitution) followed by RCN + 2 H2O → RCOOH + NH3 (Hydrolysis under reflux with mineral acid catalyst), or RCN + 0.5 LiAlH4 + (second step) 2 H2O → RCH2NH2 + 0.5 LiAl(OH)4 (under reflux in dry ether, followed by addition of H2O) An alternative method for introducing a cyano group is via the process of hydrocyanation, whereby hydrogen cyanide and alkenes combine: RCH=CH2 + HCN → RCH(CN)CH3 Metal catalysts are required for such reactions. Applications Potassium ferrocyanide is used to achieve a blue color on cast bronze sculptures during the final finishing stage of the sculpture. On its own, it will produce a very dark shade of blue and is often mixed with other chemicals to achieve the desired tint and hue. It is applied using a torch and paint brush while wearing the standard safety equipment used for any patina application: rubber gloves, safety glasses, and a respirator. The actual amount of cyanide in the mixture varies according to the recipes used by each foundry. Medical uses The cyanide compound sodium nitroprusside is occasionally used in emergency medical situations to produce a rapid decrease in blood pressure in humans; it is also used as a vasodilator in vascular research. The cobalt in artificial Vitamin B12 contains a cyanide ligand as an artifact of the purification process. During World War I, a copper cyanide compound was briefly used by Japanese physicians for the treatment of tuberculosis and leprosy. Mining Gold and silver cyanides are among the very few soluble forms of these metals, and cyanides are thus used in mining as well as electroplating, metallurgy, jewelry, and photography. In the so-called cyanide process, finely ground high-grade ore is mixed with the cyanide (concentration of about two kilogram NaCN per tonne); low-grade ores are stacked into heaps and sprayed with a cyanide solution (concentration of about one kilogram NaCN per ton). The precious-metal cations are complexed by the cyanide anions to form soluble derivatives, e.g. [Au(CN)2]− and [Ag(CN)2]−. 2 Au + 4 KCN + ½ O2 + H2O → 2 K[Au(CN)2] + 2 KOH 2 Ag + 4 KCN + ½ O2 + H2O → 2 K[Ag(CN)2] + 2 KOH Silver is less "noble" than gold and often occurs as the sulfide, in which case redox is not invoked (no O2 is required), instead a displacement reaction occurs: Ag2S + 4 KCN → 2 K[Ag(CN)2] + K2S The "pregnant liquor" containing these ions is separated from the solids, which are discarded to a tailing pond or spent heap, the recoverable gold having been removed. The metal is recovered from the "pregnant solution" by reduction with zinc dust or by adsorption onto activated carbon. This process can result in environmental and health problems. Aqueous cyanide is hydrolyzed rapidly, especially in sunlight. It can mobilize some heavy metals such as mercury if present. Gold can also be associated with arsenopyrite (FeAsS), which is similar to iron pyrite (fool's gold), wherein half of the sulfur atoms are replaced by arsenic. Gold-containing arsenopyrite ores are similarly reactive toward inorganic cyanide. Fishing Cyanides are illegally used to capture live fish near coral reefs for the aquarium and seafood markets. This fishing occurs mainly in the Philippines, Indonesia and the Caribbean to supply the 2 million marine aquarium owners in the world. In this method, a diver uses a large, needleless syringe to squirt a cyanide solution into areas where the fish are hiding, stunning them so that they can be easily gathered. Many fish caught in this fashion die immediately, or in shipping. Those that survive to find their way into pet stores often die from shock, or from massive digestive damage. The high concentrations of cyanide on reefs on which this has occurred has resulted in cases of cyanide poisoning among local fishermen and their families, as well as irreversible damage to the coral reefs themselves and other marine life in the area. Environmental organizations are critical of the practice, as are some aquarists and aquarium dealers. To prevent the trade of illegally-caught aquarium fish, the Marine Aquarium Council (Headquarters: Honolulu, Hawaii) has created a certification in which the tropical fish are caught legally with nets only. To ensure authenticity, MAC-Certified marine organisms bear the "MAC-Certified" label on the tanks and boxes in which they are kept and shipped. See MAC-certification label. . Magnesium cyanide is also used in some countries illegally to stun and harvest nektonic fish. Fumigation Cyanides are used as insecticides for the fumigating of ships. Cyanide salts are used for killing ants, and have in some places been used as rat poison (the less toxic poison arsenic is more common). Chemical tests for cyanide Prussian blue The formation of Prussian blue can be used as a test for inorganic cyanide, for instance in the sodium fusion test. Typically, iron(II) sulfate is added to a solution suspected of containing cyanide, such as the filtrate from the sodium fusion test. The resulting mixture is acidified with mineral acid. The formation of Prussian blue is a positive result for cyanide. para-Benzoquinone in DMSO A solution of para-benzoquinone in DMSO reacts with inorganic cyanide to form a cyanophenol, which is fluorescent. Illumination with a UV light gives a green/blue glow if the test is positive. Copper and an aromatic amine As used by fumigators to detect hydrogen cyanide, copper(II) salt and an aromatic amine such as benzidine is added to the sample; as an alternative to benzidine an alternative amine di-(4,4-bis-dimethylaminophenyl) methane can be used. A positive test gives a blue color. Copper(I) cyanide is poorly soluble. By sequestering the copper(I) the copper(II) is rendered a stronger oxidant. The copper, in a cyanide facilitated oxidation, converts the amine into a colored compound. The Nernst equation explains this process. Another good example of such chemistry is the way in which the saturated calomel reference electrode (SCE) works. The copper, in a cyanide facilitated oxidation converts the amine into a colored compound. Pyridine-barbituric acid colorimetry A sample containing inorganic cyanide is purged with air from a boiling acid solution into a basic absorber solution. The cyanide salt absorbed in the basic solution is buffered at pH 4.5 and then reacted with chlorine to form cyanogen chloride. The cyanogen chloride formed couples pyridine with barbituric acid to form a strongly colored red dye that is proportional to the cyanide concentration. This colorimetric method following distillation is the basis for most regulatory methods (for instance EPA 335.4) used to analyze cyanide in water, wastewater, and contaminated soils. Distillation followed by colorimetric methods, however, have been found to be prone to interferences from thiocyanate, nitrate, thiosulfate, sulfite, and sulfide that can result in both positive and negative bias. It has been recommended by the USEPA (MUR March 12, 2007) that samples containing these compounds be analyzed by Gas-Diffusion Flow Injection Analysis — Amperometry. Gas diffusion flow injection analysis — amperometry Instead of distilling, the sample is injected into an acidic stream where the HCN formed is passed under a hydrophobic gas diffusion membrane that selectively allows only HCN to pass through. The HCN that passes through the membrane is absorbed into a basic carrier solution that transports the CN to an amperometric detector that accurately measures cyanide concentration with high sensitivity. Sample pretreatment determined by acid reagents, ligands, or preliminary UV irradiation allow cyanide speciation of free cyanide, available cyanide, and total cyanide respectively. These relative simplicity of these flow injection analysis methods limit the interference experienced by the high heat of distillation and also prove to be cost effective since time consuming distillations are not required. Toxicity Many cyanide-containing compounds are highly toxic, but some are not. Prussian blue, with an approximate formula Fe7(CN)18 is the blue of blue prints and is administered orally as an antidote to poisoning by thallium and radioactive caesium-137. The most dangerous cyanides are hydrogen cyanide (HCN) and salts derived from it, such as potassium cyanide (KCN) and sodium cyanide (NaCN), among others. Also some compounds readily release HCN or the cyanide ion, such as trimethylsilyl cyanide (CH3)3SiCN upon contact with water and cyanoacrylates upon pyrolysis. The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa3) in the fourth complex of the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). It attaches to the iron within this protein. The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy. Tissues that mainly depend on aerobic respiration, such as the central nervous system and the heart, are particularly affected. Antidotes to cyanide poisoning include hydroxocobalamin and sodium nitrite which release the cyanide from the cytochrome system, and rhodanase, which is an enzyme occurring naturally in mammals that combines serum cyanide with thiosulfate, producing comparatively harmless thiocyanate. Cyanides have been used as poison many times throughout history. Its most infamous application was the use of hydrogen cyanide by the Nazi regime in Germany for mass murder in some gas chambers during the Holocaust. Cyanides have been used for murder, as in the case of Grigori Rasputin, and have also been used for suicide. Some notable cases of suicide by cyanides are Erwin Rommel, Eva Braun, Wallace Carothers, Hermann Göring, Heinrich Himmler, Alan Turing, Odilo Globocnik, Adolf Hitler (in combination with a gunshot), the residents of Jonestown and the Liberation Tigers of Tamil Eelam.

7,799 | Edmund_Burke | Edmund Burke (12 January 1729 The exact year of his birth is the subject of a great deal of controversy; 1728, 1729 and 1730 have been proposed. His date of birth is also subject to question, a problem compounded by the Julian-Gregorian changeover in 1752, during his lifetime. For a fuller treatment of the question, see Lock, pp. 16-17. Conor Cruise O'Brien (op. cit., p. 14) questions Burke's birthplace as having been in Dublin, arguing in favour of Shanballymore, Co. Cork (in the house of his uncle, James Nagle). 9 July 1797) was an Irish statesman, author, orator, political theorist, and philosopher who, after relocating to England, served for many years in the House of Commons of the United Kingdom as a member of the Whig party. He is mainly remembered for his opposition to the French Revolution. It led to his becoming the leading figure within the conservative faction of the Whig party, which he dubbed the "Old Whigs", in opposition to the pro-French-Revolution "New Whigs" led by Charles James Fox. He is generally viewed as the philosophical founder of modern conservatism. Andrew Heywood, Political Ideologies: An Introduction. Third Edition (Palgrave Macmillan, 2003), p. 74. Early life Burke was born in Dublin to a prosperous solicitor father (Richard; d. 1761) who was a member of the Protestant Church of Ireland. It is unclear if this is the same Richard Burke who converted from Catholicism. J. C. D. Clark (ed.), Reflections on the Revolution in France. A Critical Edition (Stanford University Press, 2001), p. 26, n. 13. Hereafter cited as "Clark". Paul Langford, ‘Burke, Edmund (1729/30–1797)’, Oxford Dictionary of National Biography, Oxford University Press, Sept 2004; online edn, Jan 2008, accessed 18 Oct 2008. His mother Mary (c. 1702–1770), whose maiden name was Nagle, belonged to the Roman Catholic Church and came from an impoverished but genteel County Cork family. (The name Burke is the Gaelic version of the Norman name Burgh or de Burgh, who settled in Ireland following the Norman invasion of Ireland by Henry II of England in 1172. James Prior, Life of the Right Honourable Edmund Burke. Fifth Edition (London: Henry G. Bohn, 1854), p. 1. ) Burke was raised in his father's faith and remained throughout his life a practising Anglican, unlike his sister Juliana who was brought up as and remained a Roman Catholic. His political enemies would later repeatedly accuse him of being educated at the Jesuit seminary of St. Omer's and of harbouring secret Catholic sympathies at a time when membership of the Catholic Church would have disqualified him from public office (see Penal Laws in Ireland). As Burke told Mrs. Crewe: Mr. Burke's Enemies often endeavoured to convince the World that he had been bred up in the Catholic Faith, & that his Family were of it, & that he himself had been educated at St. Omer—but this was false, as his father was a regular practitioner of the Law at Dublin, which he could not be unless of the Established Church: & it so happened that though Mr. B— was twice at Paris, he never happened to go through the Town of St. Omer. 'Extracts from Mr. Burke's Table-talk, at Crewe Hall. Written down by Mrs. Crewe, pp. 62.', Miscellanies of the Philobiblon Society. Volume VII (London: Whittingham and Wilkins, 1862-3), pp. 52-3. Once an MP, Burke was required to take the oath of allegiance and abjuration, the oath of supremacy, and declare against transubstantiation. No Catholic is known to have done so in the eighteenth century. Clark, p. 26. Although never denying his Irishness, Burke often described himself as "an Englishman". This was in an age "before 'Celtic nationalism' sought to make Irishness and Englishness incompatible". Clark, p. 25. As a child he sometimes spent time away from the unhealthy air of Dublin with his mother's family baking and eating delicious pies in the Blackwater Valley. He received his early education at a Quaker school in Ballitore, some from Dublin, and remained in correspondence with his schoolmate Mary Leadbeater, the daughter of the school's owner, throughout his life. In 1744 he proceeded to Trinity College, Dublin. In 1747, he set up a Debating Club, known as Edmund Burke's Club, which in 1770 merged with the Historical Club to form the College Historical Society, now the oldest undergraduate society in the world. The minutes of the meetings of Burke's club remain in the collection of the Historical Society. He graduated in 1748. Burke's father wished him to study for the law, and with this object he went to London in 1750 and entered the Middle Temple, but soon thereafter he gave up his legal studies in order to travel in Continental Europe. After giving up law, he attempted to earn his livelihood through writing. "The writers against religion, whilst they oppose every system, are wisely careful never to set up any of their own." A Vindication of Natural Society Burke's first published work, A Vindication of Natural Society: A View of the Miseries and Evils Arising to Mankind, appeared in Spring 1756. Burke imitated Lord Bolingbroke's style and ideas in a reductio ad absurdum of his arguments for atheistic rationalism, demonstrating their absurdity. Prior, p. 45. Jim McCue, Edmund Burke and Our Present Discontents (The Claridge Press, 1997), p. 14. Burke claimed that Bolingbroke's arguments against revealed religion could apply to all social and civil institutions. Lord Chesterfield and Bishop Warburton (and others) initially thought that the work was genuinely by Bolingbroke rather than a satire. Prior, p. 45. McCue, p. 145. In 1757 Burke published a treatise on aesthetics, A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful, which attracted the attention of prominent Continental thinkers such as Denis Diderot and Immanuel Kant. It was his only purely philosophical work, and when asked by Sir Joshua Reynolds and Dr. Laurence to expand it thirty years later, Burke replied that he was no longer fit for abstract speculation (Burke had written it before he was 19). Prior, p. 47. The following year, with Robert Dodsley, he created the influential Annual Register, a publication in which various authors evaluated the international political events of the previous year. Prior, pp. 52-3. The extent to which Burke personally contributed to the Annual Register is contested. Thomas Wellsted Copeland, 'Edmund Burke and the Book Reviews in Dodsley's Annual Register', Publications of the Modern Language Association, Vol. 57, No. 2. (Jun., 1942), pp. 446-468. Robert Murray in his biography of Burke quotes the Register as evidence of Burke's opinions yet Philip Magnus in his biography does not directly cite it as a reference. Copeland, p. 446. Burke remained its chief editor until at least 1789 and there is no evidence that any other writer contributed to it before 1766. Copeland, p. 446. In London, Burke knew many of the leading intellectuals and artists, including Samuel Johnson, David Garrick, Oliver Goldsmith, and Joshua Reynolds. Edward Gibbon described him as, 'the most eloquent and rational madman that I ever knew.' Private Letters of Edward Gibbon, II (1896) Prothero, P. (ed.). p.251 cited in The Decline and Fall of the British Empire: 1781 - 1998 (2007) Brendon, Piers. Jonathan Cape, London. p.10 ISBN 978-0-224-06222-0 On 12 March 1757 he married Jane Mary Nugent (1734–1812), daughter of a Catholic physician who had treated him at Bath. His son Richard was born on 9 February 1758. Another son, Christopher, died in infancy. At about this same time, Burke was introduced to William Gerard Hamilton (known as "Single-speech Hamilton"). When Hamilton was appointed Chief Secretary for Ireland, Burke accompanied him to Dublin as his private secretary, a position he maintained for three years. In 1765 Burke became private secretary to liberal Whig statesman Charles Watson-Wentworth, the Marquess of Rockingham, at the time Prime Minister of Great Britain, who remained Burke's close friend and associate until his premature death in 1782. Member of Parliament In December 1765 Burke entered the British Parliament as a member of the House of Commons for Wendover, a pocket borough in the control of Lord Fermanagh, later 2nd Earl Verney, a close political ally of Rockingham. After Burke's maiden speech, William Pitt the Elder said Burke had "spoken in such a manner as to stop the mouths of all Europe" and that the Commons should congratulate itself on acquiring such a member. McCue, p. 16. In 1769 Burke published, in reply to George Grenville, his pamphlet on The Present State of the Nation. In the same year he purchased the small estate of Gregories near Beaconsfield. The estate was purchased with mostly borrowed money, and though it contained an art collection that included works by Titian, Gregories nevertheless would prove to be a heavy financial burden on the MP in the following decades. Burke was never able to fully pay for the estate. His speeches and writings had now made him famous, and among other effects had brought about the suggestion that he was the author of the Letters of Junius. Burke took a leading role in the debate over the constitutional limits to the executive authority of the King. He argued strongly against unrestrained royal power and for the role of political parties in maintaining a principled opposition capable of preventing abuses by the monarch or by specific factions within the government. His most important publication in this regard was his Thoughts on the Cause of the Present Discontents of May 1770. In this work, Burke opposed the influence of the Court and defended party connections. Prior, pp. 124-5. During 1771 Burke wrote a Bill which would, if passed, have given juries the right to determine what was libel. Burke spoke in favour of the Bill but it was opposed by some, including Charles James Fox, and was not passed. Fox, when introducing his own Bill in 1791, repeated almost verbatim the text of Burke's Bill without acknowledgment. Prior, p. 127 + pp. 340-2. Burke was also prominent in securing the right to publish debates held in Parliament. Prior, p. 127. In the Annual Register for 1772 (published in July 1773) Burke condemned the Partition of Poland. He saw it as "the first very great breach in the modern political system of Europe" and upsetting the balance of power in Europe. Brendan Simms, Three Victories and a Defeat. The Rise and Fall of the First British Empire, 1714–1783 (Allen Lane, 2007), pp. 569-71. In 1774 he was elected member for Bristol, at the time "England's second city" and a large constituency with a genuine electoral contest. His Speech to the Electors at Bristol at the Conclusion of the Poll was noted for its defence of the principles of representative democracy against the notion that elected officials should be delegates: ...it ought to be the happiness and glory of a representative to live in the strictest union, the closest correspondence, and the most unreserved communication with his constituents. Their wishes ought to have great weight with him; their opinion, high respect; their business, unremitted attention. It is his duty to sacrifice his repose, his pleasures, his satisfactions, to theirs; and above all, ever, and in all cases, to prefer their interest to his own. But his unbiassed opinion, his mature judgment, his enlightened conscience, he ought not to sacrifice to you, to any man, or to any set of men living. These he does not derive from your pleasure; no, nor from the law and the constitution. They are a trust from Providence, for the abuse of which he is deeply answerable. Your representative owes you, not his industry only, but his judgment; and he betrays, instead of serving you, if he sacrifices it to your opinion. The Works of the Right Honourable Edmund Burke. Volume I (London: Henry G. Bohn, 1854), pp. 446-8. In May 1778 Burke supported a motion in Parliament to revise the restrictions on Irish trade. However his constituents in Bristol, a great trading city, urged Burke to oppose free trade with Ireland. Burke resisted these demands and said: "If, from this conduct, I shall forfeit their suffrages at an ensuing election, it will stand on record an example to future representatives of the Commons of England, that one man at least had dared to resist the desires of his constituents when his judgment assured him they were wrong". Prior, p. 175. Burke published Two Letters to Gentlemen of Bristol on the Bills relative to the Trade of Ireland in which he espoused "some of the chief principles of commerce; such as the advantage of free intercourse between all parts of the same kingdom...the evils attending restriction and monopoly...and that the gain of others is not necessarily our loss, but on the contrary an advantage by causing a greater demand for such wares as we have for sale". Prior, pp. 175-6. Burke also supported Sir George Savile's attempts to repeal some of the penal laws against Catholics. Prior, p. 176. This support for unpopular causes, notably free trade with Ireland and Catholic emancipation, led to Burke losing his seat in 1780. He also called capital punishment "the Butchery which we call justice" in 1776 and in 1780 Burke condemned the use of the pillory for two men convicted for attempting to practice sodomy. Langford. For the remainder of his parliamentary career, Burke sat for Malton, another pocket borough controlled by Rockingham. American Revolution Burke expressed his support for the grievances of the American colonies under the government of King George III and his appointed representatives. On 19 April 1774 Burke made a speech (published in January 1775) on a motion to repeal the tea duty: Again and again, revert to your old principles—seek peace and ensue it; leave America, if she has taxable matter in her, to tax herself. I am not here going into the distinctions of rights, nor attempting to mark their boundaries. I do not enter into these metaphysical distinctions; I hate the very sound of them. Leave the Americans as they anciently stood, and these distinctions, born of our unhappy contest, will die along with it...Be content to bind America by laws of trade; you have always done it...Do not burthen them with taxes...But if intemperately, unwisely, fatally, you sophisticate and poison the very source of government by urging subtle deductions, and consequences odious to those you govern, from the unlimited and illimitable nature of supreme sovereignty, you will teach them by these means to call that sovereignty itself in question...If that sovereignty and their freedom cannot be reconciled, which will they take? They will cast your sovereignty in your face. No body of men will be argued into slavery. Sir, let the gentlemen on the other side...tell me, what one character of liberty the Americans have, and what one brand of slavery they are free from, if they are bound in their property and industry by all the restraints you can imagine on commerce, and at the same time are made pack-horses of every tax you choose to impose, without the least share in granting them. When they bear the burthens of unlimited monopoly, will you bring them to bear the burthens of unlimited revenue too? The Englishman in America will feel that this is slavery; that it is legal slavery, will be no compensation either to his feelings or to his understandings. Prior, pp. 142-3. On 22 March 1775 Burke gave a speech (published in May 1775) on conciliation with America: ...the people of the colonies are descendants of Englishmen...They are therefore not only devoted to liberty, but to liberty according to English ideas and on English principles. The people are Protestants...a persuasion not only favourable to liberty, but built upon it...My hold of the colonies is in the close affection which grows from common names, from kindred blood, from similar privileges, and equal protection. These are ties which, though light as air, are as strong as links of iron. Let the colonies always keep the idea of their civil rights associated with your government,—they will cling and grapple to you, and no force under heaven will be of power to tear them from their allegiance. But let it be once understood that your government may be one thing and their privileges another, that these two things may exist without any mutual relation,—the cement is gone, the cohesion is loosened, and everything hastens to decay and dissolution. As long as you have the wisdom to keep the sovereign authority of this country as the sanctuary of liberty, the sacred temple consecrated to our common faith, wherever the chosen race and sons of England worship freedom, they will turn their faces towards you. The more they multiply, the more friends you will have; the more ardently they love liberty, the more perfect will be their obedience. Slavery they can have anywhere. It is a weed that grows in every soil. They may have it from Spain, they may have it from Prussia. But, until you become lost to all feeling of your true interest and your natural dignity, freedom they can have from none but you. Speech on Moving Resolutions for Conciliation with America, March 22, 1775 The Tory administration of Lord North (1770-1782) tried to defeat the colonists' rebellion by military force. British and American forces clashed in 1775 and in 1776 came the American Declaration of Independence. Burke was appalled by celebrations in Britain of the defeat of the Americans at New York and Pennsylvania. He claimed the English national character was being changed by this authoritarianism. Langford. In Burke's view the British government was fighting "the American English" ("our English Brethren in the Colonies"), with a German-descended King employing "the hireling sword of German boors and vassals" to destroy the colonists' English liberties. Langford. Paymaster of the Forces In Cincinnatus in Retirement (1782), James Gillray caricatured Burke's support of rights for Catholics. The fall of North led to Rockingham being recalled to power in March 1782. Burke became Paymaster of the Forces and a Privy Councillor, but without a seat in the Cabinet. Rockingham's unexpected death in July of 1782 and his replacement as Prime Minister by Shelburne put an end to his administration after only a few months. However Burke did manage to pass two Acts. The Paymaster General Act 1782 ended the post as a lucrative sinecure. Previously, Paymasters had been able to draw on money from the Treasury at their discretion. Now they were to put the money they had requested to withdraw from the Treasury into the Bank of England, from where it was to be withdrawn for specific purposes. The Treasury would receive monthly statements of the Paymaster's balance at the Bank. This Act was repealed by Shelburne's administration but the Act which replaced it repeated verbatim almost the whole text of Burke's Act. F. P. Lock, Edmund Burke. Volume I: 1730–1784 (Clarendon Press, 1999), p. 511 + n. 65. The Civil List and Secret Service Money Act 1782 was a watered down version of Burke's original intentions as outlined in his famous Speech on Economical Reform of 11 February 1780. However he managed to abolish 134 offices in the royal household and civil administration. McCue, p. 21. The third Secretary of State and the Board of Trade were abolished and pensions were limited and regulated. The Act was projected to save £72,368 a year. Lock, pp. 511-2. In February 1783 Burke resumed the post of Paymaster of the Forces when Shelburne's government fell and was replaced by a coalition headed by North and including Charles James Fox. The coalition fell in 1783, and was succeeded by the long Tory administration of William Pitt the Younger, which lasted until 1801. Burke was accordingly in opposition for the remainder of his political life. India and the Impeachment of Warren Hastings Burke’s interaction with the British dominion of India began well before the Hastings Trial. Previous to the impeachment, Parliament dealt with the Indian issue for two decades, this trial was the pinnacle of years of unrest and deliberation. Siraj Ahmed, “The Theater of the Civilized Self: Edmund Burke and the East India Trials.” Representations 78 (2002): 30. In 1781 Burke was first able to delve into the issues surrounding the East India Company when he was appointed Chairman of the Commons’ Select Committee on East Indian Affair – from that point until the end of the trial; India was Burke’s primary concern. Ibid., 30. This committee was charged “to investigate alleged injustices in Bengal, the war with Hyder Ali, and other Indian difficulties.” Russell Kirk, Edmund Burke: A Genius Reconsidered (Peru, IL: Sherwood, Sugden and Company, 1988), 2. While Burke and the committee focused their attention on these matters, a second ‘secret’ committee was formed to assess the same issues. Kirk, Edmund Burke, 108. Both committee reports were written by Burke and lead to the reassurance to the Indian princes that Britain would not wage war on them and the demand for the EIC to recall Hastings. Ibid., 108. This is Burke’s first call for real, significant change of the imperial practices. When addressing the whole House of Commons in regards to the committee’s report, Burke would describe the Indian issue as one that “began ‘in commerce’ but ‘ended in empire.’” Elizabeth D. Samet, “A Prosecutor and a Gentleman: Edmund Burke’s Idiom of Impeachment,” ELH 68, no. 2 (2001): 402. On February 28, 1785 he made his great speech on The Nabob of Arcot's Debts, where he condemned the damage he believed the East India Company had done to India. In the province of the Carnatic the Indians had constructed a system of reservoirs to make the soil fertile in a naturally dry region, and centred their society on the husbandry of water: These are the monuments of real kings, who were the fathers of their people; testators to a posterity which they embraced as their own. These are the grand sepulchres built by ambition; but by the ambition of an insatiable benevolence, which, not contented with reigning in the dispensation of happiness during the contracted term of human life, had strained, with all the reachings and graspings of a vivacious mind, to extend the dominion of their bounty beyond the limits of nature, and to perpetuate themselves through generations of generations, the guardians, the protectors, the nourishers of mankind. McCue, p. 155. Burke held that the advent of British dominion, and in particular the conduct of the East India Company had destroyed much that was good in these traditions and that, as a consequence of this, and the lack of new customs to replace them, the Indians were suffering. He set about establishing a set of British expectations, whose moral foundation would, in his opinion, warrant the empire. McCue, p. 156. On April 4, 1786, twenty-one years after the establishment of the East India Company, Burke presented the Commons with the Article of Charge of High Crimes and Misdemeanors against Warren Hastings, the former Governor General of Bengal. The trial, which did not begin until February 14, 1788, would be the “first major public discursive event of its kind in England,” Mithi Mukherjee, “Justice, War, and the Imperium: India and Britain in Edmund Burke’s Prosecutorial Speeches,” Law and History Review 23, no. 3 (2005): 589. bringing the morality and duty of imperialism to the forefront of the public’s perception. Burke was already known for his eloquent rhetorical skills and his involvement in the trial only engrossed its popularity and significance. Mukherjee, “Justice, War, and the Imperium,” 590. For the members of London’s fashionable society, the trial was a spectacle , and was not centered around Hastings’ alleged misconduct and crimes as had been Burke’s intent. Elizabeth D. Samet, “A Prosecutor and a Gentleman: Edmund Burke’s Idiom of Impeachment,” ELH 68, no. 2 (2001): 406-407. Burke's indictment, fuelled by emotional indignation, called Hastings the 'captain-general of iniquity'; who never dined without 'creating a famine'; his heart was 'gangrened to the core' and he resembled both a 'spider of Hell' and a 'ravenous vulture devouring the carcases of the dead'. Piers Brendon, The Decline and Fall of the British Empire: 1781 - 1998 (London: Jonathan Cape, 2007), p. 35. ISBN 978-0-224-06222-0 The indictment was such a philippic that, whereas it had previously seemed that Hastings would be found guilty, it actually provoked public sympathy; however, although Hastings was acquitted, the trial served to establish the principle that the Empire was a moral undertaking rather than a wholesale looting by either the East India Company or its servants. French Revolution: 1688 versus 1789 Smelling out a Rat;—or—The Atheistical-Revolutionist disturbed in his Midnight "Calculations" (1790) by Gillray, depicting a caricature of Burke with a long nose and spectacles, holding a crown and a cross. The seated man is Dr. Richard Price, who is writing "On the Benefits of Anarchy Regicide Atheism" beneath a picture of the execution of Charles I of England. Burke did not initially condemn the French Revolution. In a letter of 9 August 1789, Burke wrote: "England gazing with astonishment at a French struggle for Liberty and not knowing whether to blame or to applaud! The thing indeed, though I thought I saw something like it in progress for several years, has still something in it paradoxical and Mysterious. The spirit it is impossible not to admire; but the old Parisian ferocity has broken out in a shocking manner". Clark, p. 61. The events of 5-6 October 1789, in which a mob of Parisian women marched on Versailles to compel King Louis XVI to return to Paris, turned Burke against it. In a letter to his son Richard on 10 October he said: "This day I heard from Laurence who has sent me papers confirming the portentous state of France—where the Elements which compose Human Society seem all to be dissolved, and a world of Monsters to be produced in the place of it—where Mirabeau presides as the Grand Anarch; and the late Grand Monarch makes a figure as ridiculous as pitiable". Clark, pp. 61-2. On 4 November Charles-Jean-François Depont wrote to Burke, requesting that he endorse the Revolution. Burke replied that any critical language of it by him should be taken "as no more than the expression of doubt" but added: "You may have subverted Monarchy, but not recover'd freedom". Clark, p. 62. In the same month he described France as "a country undone". Burke's first public condemnation of the Revolution occurred on the debate in Parliament on the Army Estimates on 9 February 1790, provoked by praise of the Revolution by Pitt and Fox: Reflections on the Revolution in France, And on the Proceedings in Certain Societies in London Relative to that Event. In a Letter Intended to Have Been Sent to a Gentleman in Paris. By the Right Honourable Edmund Burke. Since the House had been prorogued in the summer much work was done in France. The French had shewn themselves the ablest architects of ruin that had hitherto existed in the world. In that very short space of time they had completely pulled down to the ground, their monarchy; their church; their nobility; their law; their revenue; their army; their navy; their commerce; their arts; and their manufactures...[there was a danger of] an imitation of the excesses of an irrational, unprincipled, proscribing, confiscating, plundering, ferocious, bloody and tyrannical democracy...[in religion] the danger of their example is no longer from intolerance, but from Atheism; a foul, unnatural vice, foe to all the dignity and consolation of mankind; which seems in France, for a long time, to have been embodied into a faction, accredited, and almost avowed. Clark, pp. 66-7. In January 1790 Burke read Dr. Richard Price's sermon of 4 November 1789 to the Revolution Society, called A Discourse On the Love of our Country. A Discourse On the Love of our Country The Revolution Society was founded to commemorate the Glorious Revolution of 1688. In this sermon Price espoused the philosophy of universal "rights of men". Price argued that love of our country "does not imply any conviction of the superior value of it to other countries, or any particular preference of its laws and constitution of government". Clark, p. 63. Instead, Englishmen should see themselves "more as citizens of the world than as members of any particular community". The debate between Price and Burke was "the classic moment at which two fundamentally different conceptions of national identity were presented to the English public". J. C. D. Clark, English Society, 1660–1832 (Cambridge University Press, 2008), p. 233. Price claimed that the principles of the Glorious Revolution included "the right to choose our own governors, to cashier them for misconduct, and to frame a government for ourselves". Immediately after reading Price's sermon, Burke wrote a draft of what would eventually become the Reflections on the Revolution in France. On 13 February 1790 there appeared a notice in the press that Burke would shortly publish a pamphlet on the Revolution and its British supporters, however he spent the year revising and expanding it. On 1 November he finally published the Reflections and it was an immediate best-seller. Clark, p. 68. Prior, p. 311. Priced at five shillings, it was more expensive than most political pamphlets but by the end of 1790 it had gone through ten printings and sold approximately 17,500 copies. A French translation appeared on 29 November and on 30 November the translator, Pierre-Gaëton Dupont, wrote to Burke saying 2,500 copies had already been sold. The French translation ran to ten printings by June 1791. F. P. Lock, Burke's Reflections on the Revolution in France (London: George Allen & Unwin, 1985), p. 132. What the Glorious Revolution had meant was important to Burke and his contemporaries, as it had been for the last one hundred years in British politics. Clark, p. 39. In the Reflections, Burke argued against Price's interpretation of the Glorious Revolution and instead gave a classic Whig defence of it. Clark, pp. 24-5, p. 34, p. 43. Burke argued against the idea of abstract, metaphysical rights of men and instead advocated national tradition: The Revolution was made to preserve our antient indisputable laws and liberties, and that antient constitution of government which is our only security for law and liberty. ... The very idea of the fabrication of a new government, is enough to fill us with disgust and horror. We wished at the period of the Revolution, and do now wish, to derive all we possess as an inheritance from our forefathers. Upon that body and stock of inheritance we have taken care not to inoculate any cyon alien to the nature of the original plant. ... Our oldest reformation is that of Magna Charta. You will see that Sir Edward Coke, that great oracle of our law, and indeed all the great men who follow him, to Blackstone, are industrious to prove the pedigree of our liberties. They endeavour to prove that the ancient charter...were nothing more than a re-affirmance of the still more ancient standing law of the kingdom. ... In the famous law...called the Petition of Right, the parliament says to the king, “Your subjects have inherited this freedom,” claiming their franchises not on abstract principles “as the rights of men,” but as the rights of Englishmen, and as a patrimony derived from their forefathers. Clark, pp. 181-3. Burke put forward that "We fear God, we look up with awe to kings; with affection to parliaments; with duty to magistrates; with reverence to priests; and with respect to nobility. Why? Because when such ideas are brought before our minds, it is natural to be so affected". Clark, pp. 250-1. Burke defended prejudice on the grounds that it is "the general bank and capital of nations, and of ages" and superior to individual reason, which is small in comparison. "Prejudice", Burke claimed, "is of ready application in the emergency; it previously engages the mind in a steady course of wisdom and virtue, and does not leave the man hesitating in the moment of decision, skeptical, puzzled, and unresolved. Prejudice renders a man's virtue his habit". Clark, pp. 251-2. Burke criticised social contract theory by claiming that society is indeed a contract, but "a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born". Clark, p. 261. Louis XVI translated the Reflections "from end to end" into French. Prior, pp. 313-4. Fellow Whig MPs Richard Sheridan and Charles James Fox disagreed with Burke and split with him. Fox thought the Reflections to be "in very bad taste" and "favouring Tory principles". L. G. Mitchell, Charles James Fox (Penguin, 1997), p. 113. Other Whigs such as the Duke of Portland and Earl Fitzwilliam privately agreed with Burke but did not wish for a public breach with their Whig colleagues. Lock, p. 134. Burke's Reflections sparked a pamphlet war. Thomas Paine penned The Rights of Man in 1791 as a response to Burke; Mary Wollstonecraft published A Vindication of the Rights of Men and James Mackintosh wrote Vindiciae Gallicae. Mackintosh was the first to see the Reflections as "the manifesto of a Counter Revolution". Mackintosh would later come to agree with Burke's views, remarking in December 1796 after meeting him, that Burke was "minutely and accurately informed, to a wonderful exactness, with respect to every fact relating to the French Revolution". Clark, p. 49. Mackintosh later said: "Burke was one of the first thinkers as well as one of the greatest orators of his time. He is without parallel in any age, excepting perhaps Lord Bacon and Cicero; and his works contain an ampler store of political and moral wisdom than can be found in any other writer whatever". Prior, p. 491. In February 1791 Burke published A Letter to a Member of the National Assembly in which he claimed the excesses of the Revolution were not accidents but designed from the beginning. He also denounced Jean-Jacques Rousseau, the philosophical influence of the Revolution, recalling his visit to Britain in 1766: "I had good opportunities of knowing his proceedings almost from day to day and he left no doubt in my mind that he entertained no principle either to influence his heart or to guide his understanding, but vanity". Prior, pp. 326-7. These events, and the disagreements which arose regarding them within the Whig party, led to its breakup and to the rupture of Burke's friendship with Fox. In debate in Parliament on Britain's relations with Russia, Fox praised the principles of the Revolution, though Burke was not able to reply at this time as he was "overpowered by continued cries of question from his own side of the House". Prior, p. 327. When Parliament was debating the Quebec Bill for a constitution for Canada, Fox praised the Revolution and criticised some of Burke's arguments, such as hereditary power. On 6 May 1791, during another debate in Parliament on the Quebec Bill, Burke used the opportunity to answer Fox and condemn the new French Constitution and "the horrible consequences flowing from the French idea of the rights of man". McCue, p. 23. Burke was interrupted, and Fox intervened to say that Burke should be allowed to carry on with his speech. However a vote of censure was moved against Burke for noticing the affairs of France, which was moved by Lord Sheffield and seconded by Fox. Prior, p. 328. Pitt made a speech praising Burke, and Fox made a speech both rebuking and complimenting Burke. He questioned the sincerity of Burke, who seemed to have forgotten the lessons he had taught him, quoting from Burke's speeches of fourteen and fifteen years before. Burke replied: Charles James Fox. It certainly was indiscreet at any period, but especially at his time of life, to parade enemies, or give his friends occasion to desert him; yet if his firm and steady adherence to the British constitution placed him in such a dilemma, he would risk all, and, as public duty and public experience taught him, with his last words exclaim, "Fly from the French Constitution". McCue, p. 23. At this point Fox whispered that there was "no loss of friendship". "I regret to say there is", Burke said, "I have indeed made a great sacrifice; I have done my duty though I have lost my friend. There is something in the detested French constitution that envenoms every thing it touches". Prior, p. 329. This provoked a reply from Fox, yet he was unable to give his speech for some time since he was overcome with tears and emotion, he appealed to Burke to remember their inalienable friendship but also repeated his criticisms of Burke and uttered "unusually bitter sarcasms". Prior, p. 329. This only aggravated the rupture between the two men. Burke was dismayed that some Whigs, instead of reaffirming the principles of the Whig party he laid out in the Reflections, had rejected them in favour of "French principles" and criticised Burke for abandoning Whig principles. Burke, wanting to demonstrate his fidelity to Whig principles and fearing that acquiescence to Fox and his followers would allow the Whig party to become a vehicle for Jacobinism, wrote that he wanted to represent the whole Whig party "as tolerating, and by a toleration, countenancing those proceedings" so that he could "stimulate them to a public declaration of what every one of their acquaintance privately knows to be...their sentiments". Frank 'O'Gorman, The Whig Party and the French Revolution (Macmillan, 1967), p. 74. Therefore on 3 August 1791 Burke published his Appeal from the New to the Old Whigs, in which he renewed his criticism of the radical revolutionary programmes inspired by the French Revolution and attacked the Whigs who supported them as holding principles contrary to those traditionally held by the Whig party. Burke owned two copies of what has been called "that practical compendium of Whig political theory", The Tryal of Dr. Henry Sacheverell (1710). Clark, p. 40. Burke wrote of the trial: "It rarely happens to a party to have the opportunity of a clear, authentic, recorded, declaration of their political tenets upon the subject of a great constitutional event like that of the [Glorious] Revolution". Clark, p. 40. Writing in the third person, Burke asserted in his Appeal: ...that the foundations laid down by the Commons, on the trial of Doctor Sacheverel, for justifying the revolution of 1688, are the very same laid down in Mr. Burke's Reflections; that is to say,—a breach of the original contract, implied and expressed in the constitution of this country, as a scheme of government fundamentally and inviolably fixed in King, Lords and Commons.—That the fundamental subversion of this antient constitution, by one of its parts, having been attempted, and in effect accomplished, justified the Revolution. That it was justified only upon the necessity of the case; as the only means left for the recovery of that antient constitution, formed by the original contract of the British state; as well as for the future preservation of the same government. These are the points to be proved. Clark, p. 40. Although Whig grandees like Portland and Fitzwilliam privately agreed with Burke's Appeal, they wished he had used more moderate language. Burke wrote of the its reception: "Not one word from one of our party. They are secretly galled. They agree with me to a title; but they dare not speak out for fear of hurting Fox. ... They leave me to myself; they see that I can do myself justice". O'Gorman, p. 75. Eventually most of the Whigs sided with Burke and voted their support for the conservative government of Pitt, which, in response to France's declaration of war against Britain, declared war on the revolutionary government of France in 1793. Burke, as a Whig, did not wish to see an absolute monarchy again in France after the extirpation of Jacobinism. Writing to an émigré in 1791, Burke expressed his views against a restoration of the ancient régime: When such a complete convulsion has shaken the State, and hardly left any thing whatsoever, either in civil arrangements, or in the Characters and disposition of mens minds, exactly where it was, whatever shall be settled although in the former persons and upon old forms, will be in some measure a new thing and will labour under something of the weakness as well as other inconveniences of a Change. My poor opinion is that you mean to establish what you call ‘L'ancien Regime,’ If any one means that system of Court Intrigue miscalled a Government as it stood, at Versailles before the present confusions as the thing to be established, that I believe will be found absolutely impossible; and if you consider the Nature, as well of persons, as of affairs, I flatter myself you must be of my opinion. That was tho' not so violent a State of Anarchy as well as the present. If it were even possible to lay things down exactly as they stood, before the series of experimental politicks began, I am quite sure that they could not long continue in that situation. In one Sense of L'Ancien Regime I am clear that nothing else can reasonably be done. Clark, pp. 104-5. On 20 June 1794 Burke received a vote of thanks from the Commons for his services in the Hastings trial and immediately resigned his seat, being replaced by his son Richard. However a terrible blow fell upon Burke in the loss of Richard in August 1794, to whom he was tenderly attached, and in whom he saw signs of promise. Langford. The King, whose favour he had gained by his attitude on the French Revolution, wished to make him Lord Beaconsfield, but the death of his son had deprived such an honour of all its attractions, and the only reward he would accept was a pension of £2,500. This pension was attacked by the Duke of Bedford and the Earl of Lauderdale, to whom Burke replied in the Letter to a Noble Lord (1796). Prior, pp. 425-6. Burke spent his final years in strong support of the war against France. His last publications were the Letters on a Regicide Peace (October 1796), called forth by the Pitt government's negotiations for peace with France. Burke regarded this as appeasement, injurious to national dignity and honour. Prior, pp. 439-40. Burke regarded the war with France as ideological, against an "armed doctrine". He wished that France would not be partitioned due to the effect this would have on the balance of power in Europe, and that the war was not against France but against the revolutionaries governing her. Prior, pp. 443-4. Burke said: "It is not France extending a foreign empire over other nations: it is a sect aiming at universal empire, and beginning with the conquest of France". Langford. Later life In November 1795 there was a debate in Parliament on the high price of corn and Burke wrote a memorandum to Pitt on the subject. In December Samuel Whitbread MP introduced a bill giving magistrates the power to fix minimum wages and Fox said he would vote for it. This debate probably led Burke to editing his memorandum as there appeared a notice that Burke would soon publish a letter on the subject to the Secretary of the Board of Agriculture (Arthur Young), but he failed to complete it. These fragments were inserted into the memorandum after his death and published posthumously in 1800 as Thoughts and Details on Scarcity. Robert Eccleshall, English Conservatism since the Restoration (London: Unwin Hyman, 1990), p. 75. In it, Burke expounded "some of the doctrines of political economists bearing upon agriculture as a trade". Prior, p. 419. Burke criticised policies such as maximum prices and state regulation of wages, and set out what the limits of government should be: That the State ought to confine itself to what regards the State, or the creatures of the State, namely, the exterior establishment of its religion; its magistracy; its revenue; its military force by sea and land; the corporations that owe their existence to its fiat; in a word, to every thing that is truly and properly public, to the public peace, to the public safety, to the public order, to the public prosperity. Eccleshall, p. 77. The economist Adam Smith remarked that Burke was "the only man I ever knew who thinks on economic subjects exactly as I do, without any previous communications having passed between us". E. G. West, Adam Smith (New York: Arlington House, 1969), p. 201. For more than a year before his death Burke knew that his stomach was "irrecoverably ruined". Langford. After hearing that Burke was nearing death, Fox wrote to Mrs. Burke enquiring after him. Fox received the reply the next day: Mrs. Burke presents her compliments to Mr. Fox, and thanks him for his obliging inquiries. Mrs. Burke communicated his letter to Mr. Burke, and by his desire has to inform Mr. Fox that it has cost Mr. Burke the most heart-felt pain to obey the stern voice of his duty in rending asunder a long friendship, but that he deemed this sacrifice necessary; that his principles continue the same; and that in whatever of life may yet remain to him, he conceives that he must live for others and not for himself. Mr. Burke is convinced that the principles which he has endeavoured to maintain are necessary to the welfare and dignity of his country, and that these principles can be enforced only by the general persuasion of his sincerity. Prior, p. 456 Burke died in Beaconsfield, Buckinghamshire on 9 July 1797. He was buried in Beaconsfield alongside his son and brother. His wife survived him by nearly fifteen years. Legacy Burke's Reflections on the Revolution in France was controversial at the time of its publication. But after his death, it was to become his best-known and most influential work. It is understood to be the manifesto in Conservative thought. In the English-speaking world, Burke is regarded by most political experts as the father of modern anglo-conservatism. His 'liberal' conservatism, which opposed governing based on abstract ideas, and preferred 'organic' reform, can be contrasted with the autocratic conservatism of Continental figures such as Joseph de Maistre. Burke's ideas placing property at the base of human development and the development of society were radical and new at the time. Burke believed that property was essential to human life. Because of his conviction that people desire to be ruled and controlled, the division of property formed the basis for social structure, helping develop control within a property-based hierarchy. He viewed the social changes brought on by property as the natural order of events that should be taking place as the human race progressed. With the division of property and the class system, he also believed that it kept the monarch in check to the needs of the classes beneath the monarch. Since property largely aligned or defined divisions of social class, class too to was seen as natural - part of a social agreement that the setting of persons into different classes is the mutual benefit of all subjects. His support for Irish Catholics and Indians often led him to be criticised by Tories. J. J. Sack, From Jacobite to Conservative. Reaction and orthodoxy in Britain, c. 1760–1832 (Cambridge University Press, 2004), p. 90. His opposition to British imperialism in Ireland and India and his opposition to French imperialism and radicalism in Europe, made it difficult for Whig or Tory to wholly accept Burke as their own. Sack, p. 95. In the nineteenth century Burke was praised by both liberals and conservatives. The Conservative Prime Minister Benjamin Disraeli "was deeply penetrated with the spirit and sentiment of Burke's later writings". William Flavelle Monypenny and George Earle Buckle, The Life of Benjamin Disraeli. Earl of Beaconsfield. Volume I. 1804–1859 (London: John Murray, 1929), p. 310. The Liberal Prime Minister William Gladstone considered Burke "a magazine of wisdom on Ireland and America" and in his diary recorded: "Made many extracts from Burke—sometimes almost divine". John Morley, The Life of William Ewart Gladstone. Volume III (1880–1898) (London: Macmillan, 1903), p. 280. The Radical MP and anti-Corn Law activist Richard Cobden often praised Burke's Thoughts and Details on Scarcity. John Morley, The Life of Richard Cobden (London: T. Fisher Unwin, 1905), p. 167. The Liberal historian Lord Acton considered Burke one of the three greatest liberals, along with William Gladstone and Thomas Babington Macaulay. Herbert Paul (ed.), Letters of Lord Acton to Mary Gladstone (Macmillan, 1914), p. 44. Macaulay recorded in his diary: "I have now finished reading again most of Burke's works. Admirable! The greatest man since Milton". Sir George Trevelyan, The Life and Letters of Lord Macaulay. Volume II (London: Longmans, 1876), p. 377. The Gladstonian Liberal MP John Morley published two books on Burke (including a biography) and was influenced by Burke, including his views on prejudice. D. A. Hamer, John Morley. Liberal Intellectual in Politics (Oxford: Clarendon Press, 1968), p. 65. The Cobdenite Radical Francis Hirst thought Burke deserved "a place among English libertarians, even though of all lovers of liberty and of all reformers he was the most conservative, the least abstract, always anxious to preserve and renovate rather than to innovate. In politics he resembled the modern architect who would restore an old house instead of pulling it down to construct a new one on the site". F. W. Hirst, Liberty and Tyranny (London: Duckworth, 1935), pp. 105-6. Two contrasting assessments of Burke were offered long after his death by Karl Marx and Winston Churchill. In Das Kapital Marx wrote: The sycophant—who in the pay of the English oligarchy played the romantic laudator temporis acti against the French Revolution just as, in the pay of the North American colonies at the beginning of the American troubles, he had played the liberal against the English oligarchy—was an out-and-out vulgar bourgeois. and Winston Churchill in "Consistency in Politics" wrote: On the one hand [Burke] is revealed as a foremost apostle of Liberty, on the other as the redoubtable champion of Authority. But a charge of political inconsistency applied to this life appears a mean and petty thing. History easily discerns the reasons and forces which actuated him, and the immense changes in the problems he was facing which evoked from the same profound mind and sincere spirit these entirely contrary manifestations. His soul revolted against tyranny, whether it appeared in the aspect of a domineering Monarch and a corrupt Court and Parliamentary system, or whether, mouthing the watch-words of a non-existent liberty, it towered up against him in the dictation of a brutal mob and wicked sect. No one can read the Burke of Liberty and the Burke of Authority without feeling that here was the same man pursuing the same ends, seeking the same ideals of society and Government, and defending them from assaults, now from one extreme, now from the other. The historian Piers Brendon asserts that Burke laid the moral foundations for the British Empire, epitomised in the trial of Warren Hastings, that was ultimately to be its undoing: when Burke stated that "The British Empire must be governed on a plan of freedom, for it will be governed by no other", K. Brittlebank, Tipu Sultan's Search for Legitimacy (Delhi, 1997), p. 27. this was "an ideological bacillus that would prove fatal. This was Edmund Burke's paternalistic doctrine that colonial government was a trust. It was to be so exercised for the benefit of subject people that they would eventually attain their birthright—freedom". Brendon, p. xviii. As a consequence of this opinion, Burke objected to the opium trade, which he called a "smuggling adventure" and condemned "the great Disgrace of the British character in India". F. G. Whelan, Edmund Burke and India (Pittsburgh, 1996), p. 96. The quotation "The only thing necessary for the triumph of evil, is for good men to do nothing" although often attributed to Burke does not occur in his works or recorded speeches. It first appeared in the 14th edition of Bartlett's Familiar Quotations (1968), which incorrectly sourced it to a letter that did not in fact contain the quote.
