buy area within a set amount of time to buy more equipment (some custom maps included neutral "buy zones" that could be used by both teams). Once the round has ended, surviving players retain their equipment for use in the next round; players who were killed begin the next round with the basic default starting equipment. Standard monetary bonuses are awarded for winning a round, losing a round, killing an enemy, being the first to instruct a hostage to follow, rescuing a hostage, planting the bomb (Terrorist) or defusing the bomb (Counter-Terrorist). The scoreboard displays team scores in addition to statistics for each player: name, kills, deaths, and ping (in milliseconds). The scoreboard also indicates whether a player is dead, carrying the bomb (on bomb maps), or is the VIP (on assassination maps), although information on players on the opposing team is hidden from a player until their death, as this information can be important. Killed players become "spectators" for the duration of the round; they cannot change their names before their next spawn, text chat cannot be sent to or received from live players, and voice chat can only be received from live players and not sent to them. Spectators are generally able to watch the rest of the round from multiple selectable views, although some servers disable some of these views to prevent dead players from relaying information about living players to their teammates through alternative media (most notably voice in the case of Internet cafes and Voice over IP programs such as TeamSpeak or Ventrilo). This form of cheating is known as "ghosting." Development Counter-Strike began as a mod of Half-Lifes engine GoldSrc. Minh Le, the mod's co-creator, had started his last semester at university, and wanted to do something in game development to help give him better job prospects. Throughout university, Le had worked on mods with the Quake engine, and on looking for this latest project, wanted to try something new and opted for GoldSrc. At the onset, Valve had not yet released the software development kit (SDK) for GoldSrc but affirmed it would be available in a few months, allowing Le to work on the character models in the interim. Once the GoldSrc SDK was available, Le estimated it took him about a month and a half to complete the programming and integrate his models for "Beta One" of Counter-Strike. To assist, Le had help from Jess Cliffe who managed the game's website and community, and had contacts within level map making community to help build some of the levels for the game. The theme of countering terrorists was inspired by Le's own interest in guns and the military, and from games like Rainbow Six and Spec Ops. Le and Cliffe continued to release Betas on a frequent basis for feedback. The initial few Betas, released starting in June 1999, had limited audiences but by the fifth one, interest in the project dramatically grew. The interest in the game drew numerous players to the website, which helped Le and Cliffe to make revenue from ads hosted on the site. Around 2000 at the time of Beta 5's release, the two were approached by Valve, offering to buy the Counter-Strike intellectual property and offering both jobs to continue its development. Both accepted the offer, and by September 2000,

Hostage rescue: The counter-terrorists must rescue a group of hostages held by the terrorists to win. The terrorists win if the time runs out with no conclusion. Assassination: One of the counter-terrorists is chosen to act as a VIP and the team must escort this player to a designated spot on the map to win the game. The terrorists win if the VIP is killed or if the time runs out with no conclusion. A player can choose to play as one of eight different default character models (four for each side, although Counter-Strike: Condition Zero added two extra models, bringing the total to ten). Players are generally given a few seconds before the round begins (known as "freeze time") to prepare and buy equipment, during which they cannot attack or move.

Both accepted the offer, and by September 2000, Valve released the first non-beta version of the game. While Cliffe stayed with Valve, Le did some additional work towards a Counter-Strike 2.0 based on Valve's upcoming Source engine, but left to start his own studio after Valve opted to shelve the sequel. Counter-Strike itself is a mod, and it has developed its own community of script writers and mod creators. Some mods add bots, while others remove features of the game, and others create different modes of play. Some mods, often called "admin plugins", give server administrators more flexible and efficient control over their servers. There are some mods which affect gameplay heavily, such as Gun Game, where players start with a basic pistol and must score kills to receive better weapons, and Zombie Mod, where one team consists of zombies and must "spread the infection" by killing the other team (using only the knife). There are also Superhero mods which mix the first-person gameplay of Counter-Strike with an experience system, allowing a player to become more powerful as they continue to play. The game is highly customizable on the player's end, allowing the user to install or even create their own custom skins, HUDs, spray graphics, sprites, and

Corot would complete his paintings back in his studio, often revising them according to his preconceptions. Pissarro, however, preferred to finish his paintings outdoors, often at one sitting, which gave his work a more realistic feel. As a result, his art was sometimes criticised as being "vulgar," because he painted what he saw: "rutted and edged hodgepodge of bushes, mounds of earth, and trees in various stages of development." According to one source, such details were equivalent to today's art showing garbage cans or beer bottles on the side of a street. This difference in style created disagreements between Pissarro and Corot. With Monet, Cézanne, and Guillaumin In 1859, while attending the free school, the Académie Suisse, Pissarro became friends with a number of younger artists who likewise chose to paint in the more realistic style. Among them were Claude Monet, Armand Guillaumin and Paul Cézanne. What they shared in common was their dissatisfaction with the dictates of the Salon. Cézanne's work had been mocked at the time by the others in the school, and, writes Rewald, in his later years Cézanne "never forgot the sympathy and understanding with which Pissarro encouraged him." As a part of the group, Pissarro was comforted from knowing he was not alone, and that others similarly struggled with their art. Pissarro agreed with the group about the importance of portraying individuals in natural settings, and expressed his dislike of any artifice or grandeur in his works, despite what the Salon demanded for its exhibits. In 1863 almost all of the group's paintings were rejected by the Salon, and French Emperor Napoleon III instead decided to place their paintings in a separate exhibit hall, the Salon des Refusés. However, only works of Pissarro and Cézanne were included, and the separate exhibit brought a hostile response from both the officials of the Salon and the public. In subsequent Salon exhibits of 1865 and 1866, Pissarro acknowledged his influences from Melbye and Corot, whom he listed as his masters in the catalogue. But in the exhibition of 1868 he no longer credited other artists as an influence, in effect declaring his independence as a painter. This was noted at the time by art critic and author Émile Zola, who offered his opinion: "Camille Pissarro is one of the three or four true painters of this day ... I have rarely encountered a technique that is so sure." Another writer tries to describe elements of Pissarro's style: "The brightness of his palette envelops objects in atmosphere ... He paints the smell of the earth." And though, on orders from the hanging Committee and the Marquis de Chennevières, Pissarro's paintings of Pontoise for example had been skyed, hung near the ceiling, this did not prevent Jules-Antoine Castagnary from noting that the qualities of his paintings had been observed by art lovers. At the age of thirty-eight, Pissarro had begun to win himself a reputation as a landscapist to rival Corot and Daubigny. In the late 1860s or early 1870s, Pissarro became fascinated with Japanese prints, which influenced his desire to experiment in new compositions. He described the art to his son Lucien: "It is marvelous. This is what I see in the art of this astonishing people ... nothing that leaps to the eye, a calm, a grandeur, an extraordinary unity, a rather subdued radiance ..." Marriage and children In 1871 in Croydon, England, he married his mother's maid, Julie Vellay, a vineyard grower's daughter, with whom he had seven children, six of which would become painters: Lucien Pissarro (1863–1944), Georges Henri Manzana Pissarro (1871–1961), Félix Pissarro (1874–1897), (1878–1952), (1881–1948), and Paul-Émile Pissarro (1884–1972). They lived outside Paris in Pontoise and later in Louveciennes, both of which places inspired many of his paintings including scenes of village life, along with rivers, woods, and people at work. He also kept in touch with the other artists of his earlier group, especially Monet, Renoir, Cézanne, and Frédéric Bazille. The London years After the outbreak of the Franco-Prussian War of 1870–71, having only Danish nationality and being unable to join the army, he moved his family to Norwood, then a village on the edge of London. However, his style of painting, which was a forerunner of what was later called "Impressionism", did not do well. He wrote to his friend, Théodore Duret, that "my painting doesn't catch on, not at all ..." Pissarro met the Paris art dealer Paul Durand-Ruel, in London, who became the dealer who helped sell his art for most of his life. Durand-Ruel put him in touch with Monet who was likewise in London during this period. They both viewed the work of British landscape artists John Constable and J. M. W. Turner, which confirmed their belief that their style of open air painting gave the truest depiction of light and atmosphere, an effect that they felt could not be achieved in the studio alone. Pissarro's paintings also began to take on a more spontaneous look, with loosely blended brushstrokes and areas of impasto, giving more depth to the work. Paintings Through the paintings Pissarro completed at this time, he records Sydenham and the Norwoods at a time when they were just recently connected by railways, but prior to the expansion of suburbia. One of the largest of these paintings is a view of St. Bartholomew's Church at Lawrie Park Avenue, commonly known as The Avenue, Sydenham, in the collection of the National Gallery in London. Twelve oil paintings date from his stay in Upper Norwood and are listed and illustrated in the catalogue raisonné prepared jointly by his fifth child Ludovic-Rodolphe Pissarro and Lionello Venturi and published in 1939. These paintings include Norwood Under the Snow, and Lordship Lane Station, views of The Crystal Palace relocated from Hyde Park, Dulwich College, Sydenham Hill, All Saints Church Upper Norwood, and a lost painting of St. Stephen's Church. Returning to France, Pissarro lived in Pontoise from 1872 to 1884. In 1890 he again visited England and painted some ten scenes of central London. He came back again in 1892, painting in Kew Gardens and Kew Green, and also in 1897, when he produced several oils described as being of Bedford Park, Chiswick, but in fact all being of the nearby Stamford Brook area except for one of Bath Road, which runs from Stamford Brook along the south edge of Bedford Park. French Impressionism When Pissarro returned to his home in France after the war, he discovered that of the 1,500 paintings he had done over 20 years, which he was forced to leave behind when he moved to London, only 40 remained. The rest had been damaged or destroyed by the soldiers, who often used them as floor mats outside in the mud to keep their boots clean. It is assumed that many of those lost were done in the Impressionist style he was then developing, thereby "documenting the birth of Impressionism." Armand Silvestre, a critic, went so far as to call Pissarro "basically the inventor of this [Impressionist] painting"; however, Pissarro's role in the Impressionist movement was "less that of the great man of ideas than that of the good counselor and appeaser ..." "Monet ... could be seen as the guiding force." He soon reestablished his friendships with the other Impressionist artists of his earlier group, including Cézanne, Monet, Manet, Renoir, and Degas. Pissarro now expressed his opinion to the group that he wanted an alternative to the Salon so their group could display their own unique styles. To assist in that endeavour, in 1873 he helped establish a separate collective, called the "Société Anonyme des Artistes, Peintres, Sculpteurs et Graveurs," which included fifteen artists. Pissarro created the group's first charter and became the "pivotal" figure in establishing and holding the group together. One writer noted that with his prematurely grey beard, the forty-three-year-old Pissarro was regarded as a "wise elder and father figure" by the group. Yet he was able to work alongside the other artists on equal terms due to his youthful temperament and creativity. Another writer said of him that "he has unchanging spiritual youth and the look of an ancestor who remained a young man". Impressionist exhibitions that shocked the critics The following year, in 1874, the group held their first 'Impressionist' Exhibition, which shocked and "horrified" the critics, who primarily appreciated only scenes portraying religious, historical, or mythological settings. They found fault with the Impressionist paintings on many grounds: The subject matter was considered "vulgar" and "commonplace," with scenes of street people going about their everyday lives. Pissarro's paintings, for instance, showed scenes of muddy, dirty, and unkempt settings; The manner of painting was too sketchy and looked incomplete, especially compared to the traditional styles of the period. The use of visible and expressive brushwork by all the artists was considered an insult to the craft of traditional artists, who often spent weeks on their work. Here, the paintings were often done in one sitting and the paints were applied wet-on-wet; The use of color by the Impressionists relied on new theories they developed, such as having shadows painted with the reflected light of surrounding, and often unseen, objects. A "revolutionary" style Pissarro showed five of his paintings, all landscapes, at the exhibit, and again Émile Zola praised his art and that of the others. In the Impressionist exhibit of 1876, however, art critic Albert Wolff complained in his review, "Try to make M. Pissarro understand that trees are not violet, that sky is not the color of fresh butter ..." Journalist and art critic Octave Mirbeau on the other hand, writes, "Camille Pissarro has been a revolutionary through the revitalized working methods with which he has endowed painting". According to Rewald, Pissarro had taken on an attitude more simple and natural than the other artists. He writes: "Rather than glorifying—consciously or not—the rugged existence of the peasants, he placed them without any 'pose' in their habitual surroundings, thus becoming an objective chronicler of one of the many facets of contemporary life." In later years, Cézanne also recalled this period and referred to Pissarro as "the first Impressionist". In 1906, a few years after Pissarro's death, Cézanne, then 67 and a role model for the new generation of artists, paid Pissarro a debt of gratitude by having himself listed in an exhibition catalogue as "Paul Cézanne, pupil of Pissarro". Pissarro, Degas, and American impressionist Mary Cassatt planned a journal of their original prints in the late 1870s, a project that nevertheless came to nothing when Degas withdrew. Art historian and the artist's great-grandson Joachim Pissarro notes that they "professed a passionate disdain for the Salons and refused to exhibit at them." Together they shared an "almost militant resolution" against the Salon, and through their later correspondences it is clear that their mutual admiration "was based on a kinship of ethical as well as aesthetic concerns". Cassatt had befriended Degas and Pissarro years earlier when she joined Pissarro's newly formed French Impressionist group and gave up opportunities to exhibit in the United States. She and Pissarro were often treated as "two outsiders" by the Salon since neither were French or had become French citizens. However, she was "fired

Together they shared an "almost militant resolution" against the Salon, and through their later correspondences it is clear that their mutual admiration "was based on a kinship of ethical as well as aesthetic concerns". Cassatt had befriended Degas and Pissarro years earlier when she joined Pissarro's newly formed French Impressionist group and gave up opportunities to exhibit in the United States. She and Pissarro were often treated as "two outsiders" by the Salon since neither were French or had become French citizens. However, she was "fired up with the cause" of promoting Impressionism and looked forward to exhibiting "out of solidarity with her new friends". Towards the end of the 1890s she began to distance herself from the Impressionists, avoiding Degas at times as she did not have the strength to defend herself against his "wicked tongue". Instead, she came to prefer the company of "the gentle Camille Pissarro", with whom she could speak frankly about the changing attitudes toward art. She once described him as a teacher "that could have taught the stones to draw correctly." Neo-Impressionist period By the 1880s, Pissarro began to explore new themes and methods of painting to break out of what he felt was an artistic "mire". As a result, Pissarro went back to his earlier themes by painting the life of country people, which he had done in Venezuela in his youth. Degas described Pissarro's subjects as "peasants working to make a living". However, this period also marked the end of the Impressionist period due to Pissarro's leaving the movement. As Joachim Pissarro points out: "Once such a die-hard Impressionist as Pissarro had turned his back on Impressionism, it was apparent that Impressionism had no chance of surviving ..." It was Pissarro's intention during this period to help "educate the public" by painting people at work or at home in realistic settings, without idealising their lives. Pierre-Auguste Renoir, in 1882, referred to Pissarro's work during this period as "revolutionary," in his attempt to portray the "common man." Pissarro himself did not use his art to overtly preach any kind of political message, however, although his preference for painting humble subjects was intended to be seen and purchased by his upper class clientele. He also began painting with a more unified brushwork along with pure strokes of color. Studying with Seurat and Signac In 1885 he met Georges Seurat and Paul Signac, both of whom relied on a more "scientific" theory of painting by using very small patches of pure colours to create the illusion of blended colours and shading when viewed from a distance. Pissarro then spent the years from 1885 to 1888 practising this more time-consuming and laborious technique, referred to as pointillism. The paintings that resulted were distinctly different from his Impressionist works, and were on display in the 1886 Impressionist Exhibition, but under a separate section, along with works by Seurat, Signac, and his son Lucien. All four works were considered an "exception" to the eighth exhibition. Joachim Pissarro notes that virtually every reviewer who commented on Pissarro's work noted "his extraordinary capacity to change his art, revise his position and take on new challenges." One critic writes: "It is difficult to speak of Camille Pissarro ... What we have here is a fighter from way back, a master who continually grows and courageously adapts to new theories." Pissarro explained the new art form as a "phase in the logical march of Impressionism", but he was alone among the other Impressionists with this attitude, however. Joachim Pissarro states that Pissarro thereby became the "only artist who went from Impressionism to Neo-Impressionism". In 1884, art dealer Theo van Gogh asked Pissarro if he would take in his older brother, Vincent, as a boarder in his home. Lucien Pissarro wrote that his father was impressed by Van Gogh's work and had "foreseen the power of this artist", who was 23 years younger. Although Van Gogh never boarded with him, Pissarro did explain to him the various ways of finding and expressing light and color, ideas which he later used in his paintings, notes Lucien.
Bedside History Obtaining a medical history is always the first "test", part of understanding the likelihood of significant disease, as detectable within the current limitations of clinical medicine. Yet heart problems often produce no symptoms until very advanced, and many symptoms, such as palpitations and sensations of extra or missing heart beats correlate poorly with relative heart health vs disease. Hence, a history alone is rarely sufficient to diagnose a heart condition. Auscultation Auscultation employs a stethoscope to more easily hear various normal and abnormal sounds, such as normal heart beat sounds and the usual heart beat sound changes associated with breathing versus heart murmurs. Laboratory Blood tests A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and evidence of existing damage. A great many more physiologic markers related to atherosclerosis and heart function are used and being developed and evaluated in research. (*) due to the high cost, LDL is usually calculated instead of being measured directly source: Beyond Cholesterol, Julius Torelli MD, 2005 Electrophysiology Electrocardiogram Electrocardiography (ECG/EKG in German vernacular. Elektrokardiogram) monitors electrical activity of the heart, primarily as recorded from the skin surface. A 12 lead recording, recording the electrical activity in three planes, anterior, posterior, and lateral is the most commonly used form. The ECG allows observation of the heart electrical activity by visualizing waveform beat origin (typically from the sinoatrial or SA node) following down the bundle of HIS and ultimately stimulating the ventricles to contract forcing blood through the body. Much can be learned by observing the QRS morphology (named for the respective portions of the polarization/repolarization waveform of the wave, P,Q,R,S,T wave). Rhythm abnormalities can also be visualized as in slow heart rate bradycardia, or fast heart rate tachycardia. Holter monitor A Holter monitor records a continuous EKG rhythm pattern (rarely a full EKG) for 24 hours or more. These monitors are used for suspected frequent rhythm abnormalities, especially ones the wearer may not recognize by symptoms.
slow heart rate bradycardia, or fast heart rate tachycardia. Holter monitor A Holter monitor records a continuous EKG rhythm pattern (rarely a full EKG) for 24 hours or more. These monitors are used for suspected frequent rhythm abnormalities, especially ones the wearer may not recognize by symptoms. They are more expensive than event monitors. Event monitor An event monitor records short term EKG rhythm patterns, generally storing the last 2 to 5 minutes, adding in new and discarding old data, for 1 to 2 weeks or more. There are several different types with different capabilities. When the wearer presses a button on the monitor, it quits discarding old and continues recording for a short additional period. The wearer then plays the recording, via a standard phone connection, to a center with compatible receiving and rhythm printing equipment, after which the monitor is ready to record again. These monitors are used for suspected infrequent rhythm abnormalities, especially ones the wearer does recognize by symptoms. They are less expensive than Holter monitors. Cardiac stress testing Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not increase any higher, despite increased exercise. A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age. This linear relation is accurate up to about age 30, after which it mildly underestimates typical maximum attainable heart rates achievable by healthy individuals. Other formulas exist, such as that by Miller (217 - (0.85 × Age)) and others. Achieving a high enough heart rate at
stories (sometimes simply by collating earlier articles), including Macchiette (1880), Occhi e nasi (1881), and Storie allegre (1887). Collodi became disenchanted with Italian politics afterward so he turned to children's literature and his first works involved translating French fairy tales into Italian. In 1875, for instance, he completed Racconti delle fate, a translation of French fairy tales by Charles Perrault. In 1876 Lorenzini wrote Giannettino (inspired by Alessandro Luigi Parravicini's Giannetto), the Minuzzolo, and Il viaggio per l'Italia di Giannettino, a pedagogic series which explored the unification of Italy through the ironic thoughts and actions of the character Giannettino. Lorenzini became fascinated by the idea of using an amiable, rascally character as a means of expressing his own convictions through allegory. In 1880 he began writing Storia di un burattino (Story of a Marionette), also called Le avventure di Pinocchio, which was published weekly in Giornale per i bambini. Pinocchio was adapted into a 1940 film by Disney that is considered to be one of Disney's greatest films. Collodi died suddenly in Florence on 26 October 1890 at the age of 63 and is interred at Cimitero Monumentale Delle Porte Sante in Florence. The National Carlo Collodi Foundation was established to promote education and the works of Carlo Lorenzini, and the Park of Pinocchio attracts many visitors each year.

Lorenzini's first publications were in his periodicals. A debut came in 1856 with the play Gli amici di casa and parodic guidebook Un romanzo in vapore, both in 1856. By 1860, he published his first notable work called Il signor Alberi ha ragione! (Mr. Alberi Is Right!), which outlined his political and cultural vision of Italy. This is the text where Lorenzini started using the Collodi pseudonym, which was taken from his mother's hometown. Collodi had also begun intense activity on other political newspapers such as Il Fanfulla; at the same time he was employed by the Censorship Commission for the Theatre.

produces the principal square root of its argument. Alternatively, the same system of complex numbers may be defined as the complex numbers whose real and imaginary parts are both constructible real numbers. For instance, the complex number has the formulas or , and its real and imaginary parts are the constructible numbers 0 and 1 respectively. These two definitions of the constructible complex numbers are equivalent. In one direction, if is a complex number whose real part and imaginary part are both constructible real numbers, then replacing and by their formulas within the larger formula produces a formula for as a complex number. In the other direction, any formula for an algebraically constructible complex number can be transformed into formulas for its real and imaginary parts, by recursively expanding each operation in the formula into operations on the real and imaginary parts of its arguments, using the expansions , where and . Algebraically constructible points The algebraically constructible points may be defined as the points whose two real Cartesian coordinates are both algebraically constructible real numbers. Alternatively, they may be defined as the points in the complex plane given by algebraically constructible complex numbers. By the equivalence between the two definitions for algebraically constructible complex numbers, these two definitions of algebraically constructible points are also equivalent. Equivalence of algebraic and geometric definitions If and are the non-zero lengths of geometrically constructed segments then elementary compass and straightedge constructions can be used to obtain constructed segments of lengths , , , and . The latter two can be done with a construction based on the intercept theorem. A slightly less elementary construction using these tools is based on the geometric mean theorem and will construct a segment of length from a constructed segment of length . It follows that every algebraically constructible number is geometrically constructible, by using these techniques to translate a formula for the number into a construction for the number. In the other direction, a set of geometric objects may be specified by algebraically constructible real numbers: coordinates for points, slope and -intercept for lines, and center and radius for circles. It is possible (but tedious) to develop formulas in terms of these values, using only arithmetic and square roots, for each additional object that might be added in a single step of a compass-and-straightedge construction. It follows from these formulas that every geometrically constructible number is algebraically constructible. Algebraic properties The definition of algebraically constructible numbers includes the sum, difference, product, and multiplicative inverse of any of these numbers, the same operations that define a field in abstract algebra. Thus, the constructible numbers (defined in any of the above ways) form a field. More specifically, the constructible real numbers form a Euclidean field, an ordered field containing a square root of each of its positive elements. Examining the properties of this field and its subfields leads to necessary conditions on a number to be constructible, that can be used to show that specific numbers arising in classical geometric construction problems are not constructible. It is convenient to consider, in place of the whole field of constructible numbers, the subfield generated by any given constructible number , and to use the algebraic construction of to decompose this field. If is a constructible real number, then the values occurring within a formula constructing it can be used to produce a finite sequence of real numbers such that, for each , is an extension of of degree 2. Using slightly different terminology, a real number is constructible if and only if it lies in a field at the top of a finite tower of real quadratic extensions, starting with the rational field where is in and for all , . It follows from this decomposition that the degree of the field extension is , where counts the number of quadratic extension steps. Analogously to the real case, a complex number is constructible if and only if it lies in a field at the top of a finite tower of complex quadratic extensions. More precisely, is constructible if and only if there exists a tower of fields where is in , and for all , . The difference between this characterization and that of the real constructible numbers is only that the fields in this tower are not restricted to being real. Consequently, if a complex number is constructible, then is a power of two. However, this necessary condition is not sufficient: there exist field extensions whose degree is a power of two that cannot be factored into a sequence of quadratic extensions. The fields that can be generated in this way from towers of quadratic extensions of are called iterated quadratic extensions of . The fields of real and complex constructible numbers are the unions of all real or complex iterated quadratic extensions of . Trigonometric numbers Trigonometric numbers are the cosines or sines of angles that are rational multiples of . These numbers are always algebraic, but they may not be constructible. The cosine or sine of the angle is constructible only for certain special numbers : The powers of two The Fermat primes, prime numbers that are one plus a power of two The products of powers of two and distinct Fermat primes. Thus, for example, is constructible because 15 is the product of two Fermat primes, 3 and 5. Impossible constructions The ancient Greeks thought that certain problems of straightedge and compass construction they could not solve were simply obstinate, not unsolvable. However, the non-constructibility of certain numbers proves that these constructions are logically impossible to perform. (The problems themselves, however, are solvable using methods that go beyond the constraint of working only with straightedge and compass, and the Greeks knew how to solve them in this way.) In particular, the algebraic formulation of constructible numbers leads to a proof of the impossibility of the following construction problems: Doubling the cube The problem of doubling the unit square is solved by the construction of another square on the diagonal of the first one, with side length and area . Analogously, the problem of doubling the cube asks for the construction of the length of the side of a cube with volume . It is not constructible, because the minimal polynomial of this length, , has degree 3 over . As a cubic polynomial whose only real root is irrational, this polynomial must be irreducible, because if it had a quadratic real root then the quadratic conjugate would provide a second real root. Angle trisection In this problem, from a given angle , one should construct an angle . Algebraically, angles can be represented by their trigonometric functions, such as their sines or cosines, which give the Cartesian coordinates of the endpoint of a line segment forming the given angle with the initial segment. Thus, an angle is constructible when is a constructible number, and the problem of trisecting the angle can be formulated as one of constructing . For example, the angle of an equilateral triangle can be constructed by compass and straightedge, with . However, its trisection cannot be constructed, because has minimal polynomial of degree 3 over . Because this specific instance of the trisection problem cannot be solved by compass and straightedge, the general problem also cannot be solved. Squaring the circle A square with area , the same area as a unit circle, would have side length , a transcendental number. Therefore, this square and its side length are not constructible, because it is not algebraic over . Regular polygons If a regular -gon is constructed with its center at the origin, the angles between the segments from the center to consecutive vertices are . The polygon can be constructed only when the cosine of this angle is a trigonometric number. Thus, for instance, a 15-gon is constructible, but the regular heptagon is not constructible, because 7 is prime but not a Fermat prime. For a more direct proof of its non-constructibility, represent the vertices of a regular heptagon as the complex roots of the polynomial . Removing the factor , dividing by , and substituting gives the simpler polynomial , an irreducible cubic with three real roots, each two times the real part of a complex-number vertex. Its roots are not constructible, so the heptagon is also not constructible. Alhazen's problem If two points and a circular mirror are given, where on the circle does one of the given points see the reflected image of the other? Geometrically, the lines from each given point to the point of reflection meet the circle at equal angles and in equal-length chords. However, it is impossible to construct a point of reflection using a compass and straightedge. In particular, for a unit circle with the two points and inside it, the solution has coordinates forming roots of an irreducible degree-four polynomial . Although its degree is a power of two, the splitting field of this polynomial has degree divisible by three, so it does not come from an iterated quadratic extension and Alhazen's problem has no compass and straightedge solution. History The birth of the concept of constructible numbers is inextricably linked with the history
proof of the equivalence between the algebraic and geometric definitions of constructible numbers has the effect of transforming geometric questions about compass and straightedge constructions into algebra, including several famous problems from ancient Greek mathematics. The algebraic formulation of these questions led to proofs that their solutions are not constructible, after the geometric formulation of the same problems previously defied centuries of attack. Geometric definitions Geometrically constructible points Let and be two given distinct points in the Euclidean plane, and define to be the set of points that can be constructed with compass and straightedge starting with and . Then the points of are called constructible points. and are, by definition, elements of . To more precisely describe the remaining elements of , make the following two definitions: a line segment whose endpoints are in is called a constructed segment, and a circle whose center is in and which passes through a point of (alternatively, whose radius is the distance between some pair of distinct points of ) is called a constructed circle. Then, the points of , besides and are: the intersection of two non-parallel constructed segments, or lines through constructed segments, the intersection points of a constructed circle and a constructed segment, or line through a constructed segment, or the intersection points of two distinct constructed circles. As an example, the midpoint of constructed segment is a constructible point. One construction for it is to construct two circles with as radius, and the line through the two crossing points of these two circles. Then the midpoint of segment is the point where this segment is crossed by the constructed line. Geometrically constructible numbers The starting information for the geometric formulation can be used to define a Cartesian coordinate system in which the point is associated to the origin having coordinates and in which the point is associated with the coordinates . The points of may now be used to link the geometry and algebra by defining a constructible number to be a coordinate of a constructible point. Equivalent definitions are that a constructible number is the -coordinate of a constructible point or the length of a constructible line segment. In one direction of this equivalence, if a constructible point has coordinates , then the point can be constructed as its perpendicular projection onto the -axis, and the segment from the origin to this point has length . In the reverse direction, if is the length of a constructible line segment, then intersecting the -axis with a circle centered at with radius gives the point . It follows from this equivalence that every point whose Cartesian coordinates are geometrically constructible numbers is itself a geometrically constructible point. For, when and are geometrically constructible numbers, point can be constructed as the intersection of lines through and , perpendicular to the coordinate axes. Algebraic definitions Algebraically constructible numbers The algebraically constructible real numbers are the subset of the real numbers that can be described by formulas that combine integers using the operations of addition, subtraction, multiplication, multiplicative inverse, and square roots of positive numbers. Even more simply, at the expense of making these formulas longer, the integers in these formulas can be restricted to be only 0 and 1. For instance, the square root of 2 is constructible, because it can be described by the formulas or . Analogously, the algebraically constructible complex numbers are the subset of complex numbers that have formulas of the same type, using a more general version of the square root that is not restricted to positive numbers but can instead take arbitrary complex numbers as its argument, and produces the principal square root of its argument. Alternatively, the same system of complex numbers may be defined as the complex numbers whose real and imaginary parts are both constructible real numbers. For instance, the complex number has the formulas or , and its real and imaginary parts are the constructible numbers 0 and 1 respectively. These two definitions of the constructible complex numbers are equivalent. In one direction, if is a complex number whose real part and imaginary part are both constructible real numbers, then replacing and by their formulas within the larger formula produces a formula for as a complex number. In the other direction, any formula for an algebraically constructible complex number can be transformed into formulas for its real and imaginary parts, by recursively expanding each operation in the formula into operations on the real and imaginary parts of its arguments, using the expansions , where and . Algebraically constructible points The algebraically constructible points may be defined as the points whose two real Cartesian coordinates are both algebraically constructible real numbers. Alternatively, they may be defined as the points in the complex plane given by algebraically constructible complex numbers. By the equivalence between the two definitions for algebraically constructible complex numbers, these two definitions of algebraically constructible points are also equivalent. Equivalence of algebraic and geometric definitions If and are the non-zero lengths of geometrically constructed segments then elementary compass and straightedge constructions can be used to obtain constructed segments of lengths , , , and . The latter two can be done with a construction based on the intercept theorem. A slightly less elementary construction using these tools is based on the geometric mean theorem and will construct a segment of length from a constructed segment of length .

This plan effectively prohibited future high-rise development in the center of downtown. The Ormsby House is the tallest building in downtown Carson City, at a height of . The structure was completed in 1972. Geography Climate Carson City features a cold semi-arid climate (Koppen: BSk) with cold winters and hot summers. The city is in a high desert river valley approximately above sea level. There are four fairly distinct seasons. Winters see typically light to moderate snowfall, with a median of . Most precipitation occurs in winter and spring, with summer and fall being fairly dry, drier than neighboring California. There are 37 days of + highs annually, with + temperatures occurring in some years. The average temperature in Carson City increased by between 1984 and 2014, a greater change than in any other city in the United States.

As of the 2010 census, there were 55,274 people, 20,171 households, and 13,252 families residing in the city. The population density was 366 people per square mile (141/km2). There were 21,283 housing units at an average density of 148/sq mi (57/km2). The racial makeup of the city was 81.1% White, 1.9% Black or African American, 2.4% Native American, 2.1% Asian, 0.2% Pacific Islander, 9.4% from other races, and 2.9% from two or more races. 21% of the population were Hispanic or Latino of any race. As of the 2000 census, there were 20,171 households, out of which 29.8% had children under the age of 18 living with them, 50.0% were married couples living together, 11.0% had a female householder with no husband present, and 34.3% were non-families. 27.8% of all households were made up of individuals, and 11.00% had someone living alone who was 65 years of age or older. The average household size was 2.44 and the average family size was 2.97. The city's age distribution was: 23.4% under the age of 18, 7.9% from 18 to 24, 28.9% from 25 to 44, 24.9% from 45 to 64, and 14.9% who were 65 years of age or older. The median age was 39 years. For every 100 females, there were 106.9 males. For every 100 females age 18 and over, there were 108.2 males. Data from the 2000 census indicates the median income for a household in the city was $41,809, and the median income for a family was $49,570. Males had a median income of $35,296 versus $27,418 for females. The per capita income for the city was $20,943. 10.0% of the population and 6.9% of families were below the poverty line. Out of the total population, 13.7% of those under the age of 18 and 5.8% of those 65 and older were living below the poverty line. Languages As of 2010, 82.3% (42,697) of Carson City residents age 5 and older spoke English at home as a first language, while 14.1% (7,325) spoke Spanish, 0.6% (318) French, and numerous Indo-Aryan languages were spoken as a main language by 0.5% (261) of the population over the age of five. In total, 17.7% (9,174) of Carson City's population age 5 and older spoke a first language other than English. Government and politics Ormsby County consolidated with Carson City in 1969, and the county simultaneously dissolved. The city is now governed by a five-member board of supervisors, consisting of a mayor and four supervisors. All members are elected at-large, but each of the four supervisors must reside in respective wards, numbered 1 through 4. The mayor and supervisors serve four year terms. Elections are staggered so the mayor and the supervisors from Wards 2 and Ward 4 are elected in presidential election years, and the supervisors from Wards 1 and 3 are elected in the even-numbered years in between (i.e., the same year as gubernatorial elections). The city is generally considered a Republican stronghold, often voting for Republicans by wide margins. In 2004, George W. Bush defeated John Kerry 57–40%. In 2008, however, Barack Obama became the first Democrat since 1964 to win Ormsby County/Carson City, defeating John McCain 49–48%, by 204 votes, a margin of under 1%. Carson City, being the state capital, is home to many political protests and demonstrations at any given time. In an attempt to either make a proposed spent nuclear fuel storage
state in 1864 during the American Civil War, Carson City was confirmed as Nevada's permanent capital. Carson City's development was no longer dependent on the mining industry and instead became a thriving commercial center. The Virginia and Truckee Railroad was built between Virginia City and Carson City. A log flume was also built from the Sierra Nevada into Carson City. The current capitol building was constructed from 1870 to 1871. The United States Mint operated the Carson City Mint between the years 1870 and 1893, which struck gold and silver coins. People came from China during that time, many to work on the railroad. Some of them owned businesses and taught school. By 1880, almost a thousand Chinese people, "one for every five Caucasians", lived in Carson City. Carson City's population and transportation traffic decreased when the Central Pacific Railroad built a line through Donner Pass, too far to the north to benefit Carson City. The city was slightly revitalized with the mining booms in Tonopah and Goldfield. The US federal building (now renamed the Paul Laxalt Building) was completed in 1890 as was the Stewart Indian School. Even these developments could not prevent the city's population from dropping to just over 1,500 people by 1930. Carson City resigned itself to small city status, advertising itself as "America's smallest capital". The city slowly grew after World War II; by 1960, it had reached its 1880 boom-time population. 20th-century revitalization and growth As early as the late 1940s, discussions began about merging Ormsby County and Carson City. By this time, the county was little more than Carson City and a few hamlets to the west. However, the effort did not pay off until 1966, when a statewide referendum approved the merger. The required constitutional amendment was passed in 1968. On April 1, 1969, Ormsby County and Carson City officially merged as the Consolidated Municipality of Carson City. With this consolidation, Carson City absorbed former town sites such as Empire City, which had grown up in the 1860s as a milling center along the Carson River and current U.S. Route 50. Carson City could now advertise itself as one of America's largest state capitals with its of city limits. In 1991, the city adopted a downtown master plan, specifying no building within of the capitol would surpass it in height. This plan effectively prohibited future high-rise development in the center of downtown. The Ormsby House is the tallest building in downtown Carson City, at a height of .

As of the 2000 census, there were 20,171 households, out of which 29.8% had children under the age of 18 living with them, 50.0% were married couples living together, 11.0% had a female householder with no husband present, and 34.3% were non-families. 27.8% of all households were made up of individuals, and 11.00% had someone living alone who was 65 years of age or older. The average household size was 2.44 and the average family size was 2.97. The city's age distribution was: 23.4% under the age of 18, 7.9% from 18 to 24, 28.9% from 25 to 44, 24.9% from 45 to 64, and 14.9% who were 65 years of age or older. The median age was 39 years. For every 100 females, there were 106.9 males. For every 100 females age 18 and over, there were 108.2 males. Data from the 2000 census indicates the median income for a household in the city was $41,809, and the median income for a family was $49,570. Males had a median income of $35,296 versus $27,418 for females. The per capita income for the city was $20,943. 10.0% of the population and 6.9% of families were below the poverty line. Out of the total population, 13.7% of those under the age of 18 and 5.8% of those 65 and older were living below the poverty line. Languages As of 2010, 82.3% (42,697) of Carson City residents age 5 and older spoke English at home as a first language, while 14.1% (7,325) spoke Spanish, 0.6% (318) French, and numerous Indo-Aryan languages were spoken as a main language by 0.5% (261) of the population over the age of five. In total, 17.7% (9,174) of Carson City's population age 5 and older spoke a first language other than English. Government and politics Ormsby County consolidated with Carson City in 1969, and the county simultaneously dissolved. The city is now governed by a five-member board of supervisors, consisting of a mayor and four supervisors. All members are elected at-large, but each of the four supervisors must reside in respective wards, numbered 1 through 4. The mayor and supervisors serve four year terms. Elections are staggered so the mayor and the supervisors from Wards 2 and Ward 4 are elected in presidential election years, and the supervisors from Wards 1 and 3 are elected in the even-numbered years in between (i.e., the same year as gubernatorial elections). The city is generally considered a Republican stronghold, often voting for Republicans by wide margins. In 2004, George W. Bush defeated John Kerry 57–40%. In 2008, however, Barack Obama became the first Democrat since 1964 to win Ormsby County/Carson City, defeating John McCain 49–48%, by 204 votes, a margin of under 1%. Carson City, being the state capital, is home to many political protests and demonstrations at any given time. In an attempt to either make a proposed
unique solution. Gorenstein (d.1992), Lyons, and Solomon are gradually publishing a simplified and revised version of the proof. Statement of the classification theorem The classification theorem has applications in many branches of mathematics, as questions about the structure of finite groups (and their action on other mathematical objects) can sometimes be reduced to questions about finite simple groups. Thanks to the classification theorem, such questions can sometimes be answered by checking each family of simple groups and each sporadic group. Daniel Gorenstein announced in 1983 that the finite simple groups had all been classified, but this was premature as he had been misinformed about the proof of the classification of quasithin groups. The completed proof of the classification was announced by after Aschbacher and Smith published a 1221-page proof for the missing quasithin case. Overview of the proof of the classification theorem wrote two volumes outlining the low rank and odd characteristic part of the proof, and wrote a 3rd volume covering the remaining characteristic 2 case. The proof can be broken up into several major pieces as follows: Groups of small 2-rank The simple groups of low 2-rank are mostly groups of Lie type of small rank over fields of odd characteristic, together with five alternating and seven characteristic 2 type and nine sporadic groups. The simple groups of small 2-rank include: Groups of 2-rank 0, in other words groups of odd order, which are all solvable by the Feit–Thompson theorem. Groups of 2-rank 1. The Sylow 2-subgroups are either cyclic, which is easy to handle using the transfer map, or generalized quaternion, which are handled with the Brauer–Suzuki theorem: in particular there are no simple groups of 2-rank 1 except for the cyclic group of order two. Groups of 2-rank 2. Alperin showed that the Sylow subgroup must be dihedral, quasidihedral, wreathed, or a Sylow 2-subgroup of U3(4). The first case was done by the Gorenstein–Walter theorem which showed that the only simple groups are isomorphic to L2(q) for q odd or A7, the second and third cases were done by the Alperin–Brauer–Gorenstein theorem which implies that the only simple groups are isomorphic to L3(q) or U3(q) for q odd or M11, and the last case was done by Lyons who showed that U3(4) is the only simple possibility. Groups of sectional 2-rank at most 4, classified by the Gorenstein–Harada theorem. The classification of groups of small 2-rank, especially ranks at most 2, makes heavy use of ordinary and modular character theory, which is almost never directly used elsewhere in the classification. All groups not of small 2 rank can be split into two major classes: groups of component type and groups of characteristic 2 type. This is because if a group has sectional 2-rank at least 5 then MacWilliams showed that its Sylow 2-subgroups are connected, and the balance theorem implies that any simple group with connected Sylow 2-subgroups is either of component type or characteristic 2 type. (For groups of low 2-rank the proof of this breaks down, because theorems such as the signalizer functor theorem only work for groups with elementary abelian subgroups of rank at least 3.) Groups of component type A group is said to be of component type if for some centralizer C of an involution, C/O(C) has a component (where O(C) is the core of C, the maximal normal subgroup of odd order). These are more or less the groups of Lie type of odd characteristic of large rank, and alternating groups, together with some sporadic groups. A major step in this case is to eliminate the obstruction of the core of an involution. This is accomplished by the B-theorem, which states that every component of C/O(C) is the image of a component of C. The idea is that these groups have a centralizer of an involution with a component that is a smaller quasisimple group, which can be assumed to be already known by induction. So to classify these groups one takes every central extension of every known finite simple group, and finds all simple groups with a centralizer of involution with this as a component. This gives a rather large number of different cases to check: there are not only 26 sporadic groups and 16 families of groups of Lie type and the alternating groups, but also many of the groups of small rank or over small fields behave differently from the general case and have to be treated separately, and the groups of Lie type of even and odd characteristic are also quite different. Groups of characteristic 2 type A group is of characteristic 2 type if the generalized Fitting subgroup F*(Y) of every 2-local subgroup Y is a 2-group. As the name suggests these are roughly the groups of Lie type over fields of characteristic 2, plus a handful of others that are alternating or sporadic or of odd characteristic. Their classification is divided into the small and large rank cases, where the rank is the largest rank of an odd abelian subgroup normalizing a nontrivial 2-subgroup, which is often (but not always) the same as the rank of a Cartan subalgebra when the group is a group of Lie type in characteristic 2. The rank 1 groups are the thin groups, classified by Aschbacher, and the rank 2 ones are the notorious quasithin groups, classified by Aschbacher and Smith. These correspond roughly to groups of Lie type of ranks 1 or 2 over fields of characteristic 2. Groups of rank at least 3 are further subdivided
of others that are alternating or sporadic or of odd characteristic. Their classification is divided into the small and large rank cases, where the rank is the largest rank of an odd abelian subgroup normalizing a nontrivial 2-subgroup, which is often (but not always) the same as the rank of a Cartan subalgebra when the group is a group of Lie type in characteristic 2. The rank 1 groups are the thin groups, classified by Aschbacher, and the rank 2 ones are the notorious quasithin groups, classified by Aschbacher and Smith. These correspond roughly to groups of Lie type of ranks 1 or 2 over fields of characteristic 2. Groups of rank at least 3 are further subdivided into 3 classes by the trichotomy theorem, proved by Aschbacher for rank 3 and by Gorenstein and Lyons for rank at least 4. The three classes are groups of GF(2) type (classified mainly by Timmesfeld), groups of "standard type" for some odd prime (classified by the Gilman–Griess theorem and work by several others), and groups of uniqueness type, where a result of Aschbacher implies that there are no simple groups. The general higher rank case consists mostly of the groups of Lie type over fields of characteristic 2 of rank at least 3 or 4. Existence and uniqueness of the simple groups The main part of the classification produces a characterization of each simple group. It is then necessary to check that there exists a simple group for each characterization and that it is unique. This gives a large number of separate problems; for example, the original proofs of existence and uniqueness of the monster group totaled about 200 pages, and the identification of the Ree groups by Thompson and Bombieri was one of the hardest parts of the classification. Many of the existence proofs and some of the uniqueness proofs for the sporadic groups originally used computer calculations, most of which have since been replaced by shorter hand proofs. History of the proof Gorenstein's program In 1972 announced a program for completing the classification of finite simple groups, consisting of the following 16 steps: Groups of low 2-rank. This was essentially done by Gorenstein and Harada, who classified the groups with sectional 2-rank at most 4. Most of the cases of 2-rank at most 2 had been done by the time Gorenstein announced his program. The semisimplicity of 2-layers. The problem is to prove that the 2-layer of the centralizer of an involution in a simple group is semisimple. Standard form in odd characteristic. If a group has an involution with a 2-component that is a group of Lie type of odd characteristic, the goal is to show that it has a centralizer of involution in "standard form" meaning that a centralizer of involution has a component that is of Lie type in odd characteristic and also has a centralizer of 2-rank 1. Classification of groups of odd type. The problem is to show that if a group has a centralizer of involution in "standard form" then it is a group of Lie type of odd characteristic. This was solved by Aschbacher's classical involution theorem. Quasi-standard form Central involutions Classification of alternating groups. Some sporadic groups Thin groups. The simple thin finite groups, those with 2-local p-rank at most 1 for odd primes p, were classified by Aschbacher in 1978 Groups with a strongly p-embedded subgroup for p odd The signalizer functor method for odd primes. The main problem is to prove a signalizer functor theorem for nonsolvable signalizer functors. This was solved by McBride in 1982. Groups of characteristic p type. This is the problem of groups with a strongly p-embedded 2-local subgroup with p odd, which was handled by Aschbacher. Quasithin groups. A quasithin group is one whose 2-local subgroups have p-rank at most 2 for all odd primes p, and the problem is to classify the simple ones of characteristic 2 type. This was completed by Aschbacher and Smith in 2004. Groups of low 2-local 3-rank. This was essentially solved by Aschbacher's trichotomy theorem for groups with e(G)=3. The main change is that 2-local 3-rank is replaced by 2-local p-rank for odd primes. Centralizers of 3-elements in standard form. This was essentially done by the Trichotomy theorem. Classification of simple groups of characteristic 2 type. This was handled by the Gilman–Griess theorem, with 3-elements replaced by p-elements for odd primes. Timeline of the proof Many of the items in the list below are taken from . The date given is usually the publication date of the complete proof of a result, which is sometimes several years later than the proof or first announcement of the result, so some of the items appear in the "wrong" order. Second-generation classification The proof of the theorem, as it stood around 1985 or so, can be called first generation. Because of the extreme length of the first generation proof, much effort has been devoted to finding a simpler proof, called a second-generation classification proof. This effort, called "revisionism", was originally led by Daniel Gorenstein. , nine volumes of the second generation proof have been published (Gorenstein, Lyons & Solomon 1994, 1996, 1998, 1999, 2002, 2005, 2018a, 2018b, 2021). In 2012 Solomon estimated that the project would need another 5 volumes, but said that progress on them was slow. It is estimated that the new proof will eventually fill approximately 5,000 pages. (This length stems in part from the second generation proof being written in a more relaxed style.) However, with the publication of volume 9 of the GLS series, and including the Aschbacher–Smith contribution, this estimate was already reached, with several more volumes still in preparation (the rest of what was originally intended for volume 9, plus projected volumes 10 and 11). Aschbacher and Smith wrote their two volumes devoted to the quasithin case in such a way that those volumes can be part of the second generation proof. Gorenstein and his collaborators have given several reasons why a simpler proof is possible. The most important thing is that the correct, final statement of the theorem is now known. Simpler techniques can be applied that are known to be adequate for the types of groups we know to be finite simple. In contrast, those who worked on the first generation proof did not know how many sporadic groups there were, and in fact some of the sporadic groups (e.g., the Janko groups) were discovered while proving other cases of the classification theorem. As a result, many of the pieces of the theorem were proved using techniques that were overly general. Because the conclusion was unknown, the first generation proof consists of many stand-alone theorems, dealing with important
the loss of craft specialisation caused by increased use of copper tools. The Tehran Plain findings illustrate the effects of the introduction of copper working technologies on the in-place systems of lithic craft specialists and raw materials. Networks of exchange and specialized processing and production that had evolved during the Neolithic seem to have collapsed by the Middle Chalcolithic ( 4500–3500 BC) and been replaced by the use of local materials by a primarily household-based production of stone tools. Europe An archaeological site in Serbia contains the oldest securely dated evidence of coppermaking from circa 7,500 years ago. The find in June 2010 extends the known record of copper smelting by about 800 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from a single source. In Serbia, a copper axe was found at Prokuplje, which indicates use of metal in Europe circa 7,500 years ago (5500 BC), many years earlier than previously believed. Knowledge of the use of copper was far more widespread than the metal itself. The European Battle Axe culture used stone axes modeled on copper axes, even with moulding carved in the stone. Ötzi the Iceman, who was found in the Ötztal Alps in 1991 and whose remains were dated to about 3300 BC, was found with a Mondsee copper axe. Examples of Chalcolithic cultures in Europe include Vila Nova de São Pedro and Los Millares on the Iberian Peninsula. Pottery of the Beaker people has been found at both sites, dating to several centuries after copper-working began there. The Beaker culture appears to have spread copper and bronze technologies in Europe, along with Indo-European languages. In Britain, copper was used between the 25th and 22nd centuries BC, but some archaeologists do not recognise a British Chalcolithic because production and use was on a small scale. South Asia According to Parpola (2005), ceramic similarities between the Indus Valley Civilisation, southern Turkmenistan, and northern Iran during 4300–3300 BC of the Chalcolithic period suggest considerable mobility and trade. The term "Chalcolithic" has also been used in the context of the South Asian Stone Age. In Bhirrana, the earliest Indus civilization site, copper bangles and arrowheads were found. The inhabitants of Mehrgarh in present-day Pakistan fashioned tools with local copper ore between 7000 and 3300 BC. At the Nausharo site dated to 4500 years ago, a pottery workshop in province of Balochistan, Pakistan, were unearthed 12 blades or blade fragments. These blades are long and and relatively thin. Archaeological experiments show that these blades were made with a copper indenter and functioned as a potter's tool to trim and shape unfired pottery. Petrographic analysis indicates local pottery manufacturing, but also reveals the existence of a few exotic black-slipped pottery items from the Indus Valley. Pre-Columbian Americas There was an independent invention of copper smelting first by Andean civilizations in South America. The term "Chalcolithic" is also applied to American civilizations that already used copper and copper alloys thousands of years before the European migration. Besides cultures in the Andes and Mesoamerica, the Old Copper Complex, centered in the Upper Great Lakes region; present-day Michigan and Wisconsin in the United States—mined and fabricated copper as tools, weapons, and personal ornaments. The evidence of smelting or alloying that has been found in north America is subject to some dispute and a common assumption by archaeologists is that objects were cold-worked into shape. Artifacts from some of these sites have been dated to 4000–1000 BC, making them some of the oldest Chalcolithic sites in the world. Furthermore, some archaeologists find artifactual and structural evidence of casting by Hopewellian and Mississippian peoples to be demonstrated in the archaeological record. East Asia In the 5th millennium BC copper artifacts start to appear in East Asia, such as in the Jiangzhai and Hongshan cultures, but those metal artifacts were not widely used. While copper objects may occasionally appear early on, these finds do not represent a regular practice of copper metallurgy which, in East Asia, begins with the entry of Afanasievo groups into western Mongolia towards the end of 4th millennium and beginning of the third millennium BC. Sub-Saharan Africa In the region
misunderstanding began among those who did not know Italian. The Chalcolithic was seen as a new -lithic age, a part of the Stone Age in which copper was used, which may appear paradoxical. Today, Copper Age, Eneolithic and Chalcolithic are used synonymously to mean Evans's original definition of Copper Age. The literature of European archaeology in general avoids the use of "Chalcolithic" (the term "Copper Age" is preferred), whereas Middle Eastern archaeologists regularly use it. "Chalcolithic" is not generally used by British prehistorians, who disagree as to whether it applies in the British context. Near East The emergence of metallurgy may have occurred first in the Fertile Crescent. The earliest use of lead is documented here from the late Neolithic settlement of Yarim Tepe in Iraq, The earliest lead (Pb) finds in the ancient Near East are a 6th millennium BC bangle from Yarim Tepe in northern Iraq and a slightly later conical lead piece from Halaf period Arpachiyah, near Mosul. As native lead is extremely rare, such artifacts raise the possibility that lead smelting may have begun even before copper smelting. Copper smelting is also documented at this site at about the same time period (soon after 6000 BC), although the use of lead seems to precede copper smelting. Early metallurgy is also documented at the nearby site of Tell Maghzaliyah, which seems to be dated even earlier, and completely lacks pottery. The Timna Valley contains evidence of copper mining in 7000–5000 BC. The process of transition from Neolithic to Chalcolithic in the Middle East is characterized in archaeological stone tool assemblages by a decline in high quality raw material procurement and use. This dramatic shift is seen throughout the region, including the Tehran Plain, Iran. Here, analysis of six archaeological sites determined a marked downward trend in not only material quality, but also in aesthetic variation in the lithic artefacts. Fazeli et al. use these results as evidence of the loss of craft specialisation caused by increased use of copper tools. The Tehran Plain findings illustrate the effects of the introduction of copper working technologies on the in-place systems of lithic craft specialists and raw materials. Networks of exchange and specialized processing and production that had evolved during the Neolithic seem to have collapsed by the Middle Chalcolithic ( 4500–3500 BC) and been replaced by the use of local materials by a primarily household-based production of stone tools.

bodily harm by the state court in Düsseldorf. In September 2007, a Frankfurt am Main appeals court found that the circumcision of an 11-year-old boy without his approval was an unlawful personal injury. The boy, whose parents were divorced, was visiting his Muslim father during a vacation when his father forced him to be ritually circumcised. The boy had planned to sue his father for . In May 2012, the Cologne regional appellate court ruled that religious circumcision of male children amounts to bodily injury, and is a criminal offense in the area under its jurisdiction. The decision based on the article "Criminal Relevance of Circumcising Boys. A Contribution to the Limitation of Consent in Cases of Care for the Person of the Child" published by Holm Putzke, a German law professor at the University of Passau. The court arrived at its judgment by application of the human rights provisions of the Basic Law, a section of the Civil Code, and some sections of the Criminal Code to non-therapeutic circumcision of male children. Some observers said it could set a legal precedent that criminalizes the practice. Jewish and Muslim groups were outraged by the ruling, viewing it as trampling on freedom of religion. The German ambassador to Israel, Andreas Michaelis, told Israeli lawmakers that Germany was working to resolve the issue and that it doesn't apply at a national level, but instead only to the local jurisdiction of the court in Cologne. The Council of the Coordination of Muslims in Germany condemned the ruling, stating that it is "a serious attack on religious freedom". Ali Kizilkaya, a spokesman of the council, stated that, "The ruling does not take everything into account, religious practice concerning circumcision of young Muslims and Jews has been carried out over the millennia on a global level." The Roman Catholic archbishop of Aachen, Heinrich Mussinghoff, said that the ruling was "very surprising", and the contradiction between "basic rights on freedom of religion and the well-being of the child brought up by the judges is not convincing in this very case". Hans Ulrich Anke, the head of the Protestant Church in Germany, said the ruling should be appealed since it didn't "sufficiently" consider the religious significance of the rite. A spokesman, Steffen Seibert, for German Chancellor Angela Merkel stated that Jewish and Muslim communities will be free to practice circumcision responsibly, and the government would find a way around the local ban in Cologne. The spokesman stated "For everyone in the government it is absolutely clear that we want to have Jewish and Muslim religious life in Germany. Circumcision carried out in a responsible manner must be possible in this country without punishment." In July 2012, a group of rabbis, imams, and others said that they view the ruling against circumcision "an affront on our basic religious and human rights". The joint statement was signed by leaders of groups including Germany's Turkish-Islamic Union for Religious Affairs, the Islamic Center Brussels, the Rabbinical Centre of Europe, the European Jewish Parliament and the European Jewish Association, who met with members of European Parliament from Germany, Finland, Belgium, Italy, and Poland. European rabbis, who urged Jews to continue circumcision, planned further talks with Muslim and Christian leaders to determine how they can oppose the ban together. The Jewish Hospital of Berlin suspended the practice of male circumcision. On 19 July 2012, a joint resolution of the CDU/CSU, SPD and FDP factions in the Bundestag requesting the executive branch to draft a law permitting circumcision of boys to be performed without unnecessary pain in accordance with best medical practice carried with a broad majority. The New York Times reported that the German Medical Association "condemned the ruling for potentially putting children at risk by taking the procedure out of the hands of doctors, but it also warned surgeons note to perform circumcisions for religious reasons until legal clarity was established". The ruling was supported by Deutsche Kinderhilfe, a German child rights organization, which asked for a two-year moratorium to discuss the issue and pointed out that religious circumcision may contravene the Convention on the Rights of the Child (Article 24.3: "States Parties shall take all effective and appropriate measures with a view to abolishing traditional practices prejudicial to the health of children."). The German Academy for Pediatric and Adolescent Medicine (Deutsche Akademie für Kinder- und Jugendmedizin e.V., DAKJ), the German Association for Pediatric Surgery (Deutsche Gesellschaft für Kinderchirurgie, DGKCH) and the Professional Association of Pediatric and Adolescent Physicians (Berufsverband der Kinder- und Jugendärzte) took a firm stand against non-medical routine infant circumcision. In July, in Berlin, a criminal complaint was lodged against Rabbi Yitshak Ehrenberg for "causing bodily harm" by performing religious circumcision, and for vocal support of the continuation of the practice. In September, the prosecutors dismissed the complaint, concluding that "there is no proof to establish that the rabbi's conduct met the 'condition of a criminal' violation". In September, Reuters reported "Berlin's senate said doctors could legally circumcise infant boys for religious reasons in its region, given certain conditions." On 12 December 2012, following a series of hearings and consultations, the Bundestag adopted the proposed law explicitly permitting non-therapeutic circumcision to be performed under certain conditions; it is now §1631(d) in the German Civil Code. The vote tally was 434 ayes, 100 noes, and 46 abstentions. Following approval by the Bundesrat and signing by the Bundespräsident, the new law became effective on 28 December 2012 a day after its publication in the Federal Gazette. Iceland In May 2005, Iceland amended its General Penal Code to criminalise female genital mutilation In February 2018, the Progressive Party proposed a bill that would change the words "girl child" to "child" and "her sexual organs" to "[their] sexual organs", thereby making Iceland the first European country to ban male circumcision for non-medical reasons. The bill discussed in the Alþing, the Icelandic parliament, claimed the practice harmed the physical integrity of young boys, was often performed without anaesthesia and in an unhygienic manner by religious leaders instead of medical experts. These facts were deemed incompatible with the United Nations Convention on the Rights of the Child (1990). Critics argued the bill infringed on religious freedom or constituted antisemitism or anti-Muslim bigotry, making it hard for Muslims and Jews to live there. Silja Dögg Gunnarsdóttir, who proposed the ban, retorted that Iceland had already prohibited female circumcision in 2005, and "If we have laws banning circumcision for girls, then we should do so for boys." On 29 April, the bill was sent back to Parliament for revisions. On 25 March 2018, members of Jews Against Circumcision spoke in the Alþing expressing their support for the proposed ban, dismissing claims that it was motivated by antisemitism, anti-Muslim bigotry, xenophobia or anti-immigration sentiment. The law was put on hold in 2018 following pressure from the United States, Israel, and various lobbyist groups. In favour of the proposed ban (March 2018) Progressive Party People's Party Left-Green Movement Pirate Party Jews Against Circumcision Against the proposed ban (March 2018) European Jewish Congress Islamic Cultural Centre of Iceland Catholic Church Anti-Defamation League Ireland In October 2005 a Nigerian man was cleared of a charge of reckless endangerment over the death of a baby from hemorrhage and shock after he had circumcised the child. The judge directed the jury not to "bring what he called their white western values to bear when they were deciding this case" and effectively imposed a not guilty verdict on the jury. After deliberating for an hour and a half they found the defendant not guilty. Israel In Israel, Jewish circumcision is entirely legal. The circumcision rate is very high in Israel, although some limited data suggests the practice is slowly declining. According to an online survey by the parents' portal Mamy in 2006, the rate was 95%, while earlier estimates put it at 98–99%. Ben Shalem, an organisation dedicated to the abolition of circumcision, petitioned the Supreme Court in 1999 on the grounds that circumcision violated human dignity, children's rights and criminal law. The petition was rejected. In 2013, a Rabbinical court in Israel ordered a mother in the midst of divorce proceedings to circumcise her son in accordance with the father's wishes, or pay a fine of 500 Israeli Shekel for every day that the child is not circumcised. She appealed against the Rabbinical court ruling and the High Court ruled in her favour stating, among other considerations, the basic right of freedom from religion. Netherlands The Royal Dutch Medical Association (KNMG) finds non-therapeutic circumcision of male minors to be in conflict with children's right to autonomy and physical integrity, and that there are good reasons for its legal prohibition, as exists for female genital mutilation: In May 2008 a father who had his two sons, aged 3 and 6 circumcised against the will of their mother was found not guilty of abuse as the circumcision was performed by a physician and due to the court's restraint in setting a legal precedent; instead he was given a 6-week suspended jail sentence for taking the boys away from their mother against her will. The parquet of the Supreme Court of the Netherlands made an elaborate statement on the legal status of circumcision on 5 July 2011 in the course of a criminal case. First, the parquet notes that there is no law that specifically prohibits the circumcision of boys, nor that the practice falls under the more general crime of (zware) mishandeling ('(grave) assault'). 'Genital mutilation of girls in any case undoubtedly falls under (zware) mishandeling (Art. 300–303 Dutch Criminal Code). Whereas most forms of genital cutting of girls are generally marked as genital mutilation, a similar communis opinio regarding genital cutting of boys does not yet exist so far.' The Supreme Court acknowledged that society's attitudes on genital cutting of boys had been gradually shifting over the course of years, and that 'the increasing concern [in the medical world] about the harm and the risk of complications during a circumcision is indeed relevant', but that overall there were not enough reasons yet to proceed to criminalisation. Neither could intentional infliction of grave bodily harm (Art. 82 Dutch Criminal Code) be applied to the normal circumstances of a competently and hygienically performed circumcision in a clinic. And because young children are incapable of exercising the right to self-determination, parents ought to do this on their behalf. They can both request a circumcision to be performed, as well as consent to it being performed, on the grounds of their parental authority. However, it is important that both parents consent to the procedure.

In September 2013, the Children's ombudsmen in all Nordic countries issued a statement by which they called for a ban on circumcision of minors for non-medical reasons, stating that such circumcisions violate the rights of children after the Convention on the Rights of the Child to co-determination and protection from harmful traditions. A bill on ritual circumcision of boys was passed (against two votes) in the Norwegian Parliament in June 2014, with the new law going into effect on 1 January 2015. This law explicitly allows Jews to practice brit milah and obligates the Norwegian Health Care regions to offer the Muslim minority a safe and affordable procedure. Local anaesthesia needs to be applied and a licensed physician needs to be present at the circumcision, which hospitals started to perform in March 2015. In May 2017, the right-wing Progress Party proposed to ban circumcision for males under sixteen. In favour of a ban Centre Party (under 18, since 2012) Progress Party (under 16, since 2017) South Africa The Children's Act 2005 makes the circumcision of male children under 16 unlawful except for religious or medical reasons. In the Eastern Cape province the Application of Health Standards in Traditional Circumcision Act, 2001, regulates traditional circumcision, which causes the death or mutilation of many youths by traditional surgeons each year. Among other provisions, the minimum age for circumcision is age 18. In 2004, a 22-year-old Rastafarian convert was forcibly circumcised by a group of Xhosa tribal elders and relatives. When he first fled, two police returned him to those who had circumcised him. In another case, a medically circumcised Xhosa man was forcibly recircumcised by his father and community leaders. He laid a charge of unfair discrimination on the grounds of his religious beliefs, seeking an apology from his father and the Congress of Traditional Leaders of South Africa. According to South African newspapers, the subsequent trial became "a landmark case around forced circumcision". In October 2009, the Eastern Cape High Court at Bhisho (sitting as an Equality Court) clarified that circumcision is unlawful unless done with the full consent of the initiate. Slovenia The Slovenian Human Rights Ombudsman finds that circumcision for non-medical reasons is a violation of children's rights, that ritual circumcision for religious reasons is unacceptable in Slovenia for both legal and ethical reasons, and should not be performed by doctors: Sweden The Swedish Medical Association finds no known medical benefits to circumcision of children, and thus strong reasons to wait until the boy is old and mature enough to give informed consent, aiming at ceasing all non-medically justified circumcision without prior consent: In 2001, the Parliament of Sweden enacted a law allowing only persons certified by the National Board of Health to circumcise infants. It requires a medical doctor or an anesthesia nurse to accompany the circumciser and for anaesthetic to be applied beforehand. After the first two months of life circumcisions can only be performed by a physician. The stated purpose of the law was to increase the safety of the procedure. Swedish Jews and Muslims objected to the law, and in 2001, the World Jewish Congress called it "the first legal restriction on Jewish religious practice in Europe since the Nazi era". The requirement for an anaesthetic to be administered by a medical professional is a major issue, and the low degree of availability of certified professionals willing to conduct circumcision has also been subject to criticism. According to a survey, two out of three paediatric surgeons said they refuse to perform non-therapeutic circumcision, and less than half of all county councils offer it in their hospitals. However, in 2006, the U.S. State Department stated, in a report on Sweden, that most Jewish mohels had been certified under the law and 3000 Muslim and 40–50 Jewish boys were circumcised each year. An estimated 2000 of these are performed by persons who are neither physicians nor have officially recognised certification. The Swedish National Board of Health and Welfare reviewed the law in 2005 and recommended that it be maintained, but found that the law had failed with regard to the intended consequence of increasing the safety of circumcisions. A later report by the Board criticised the low level of availability of legal circumcisions, partly due to reluctance among health professionals. To remedy this, the report suggested a new law obliging all county councils to offer non-therapeutic circumcision in their hospitals, but this was later abandoned in favour of a non-binding recommendation. In 2013, the children's ombudsmen of all Nordic countries – Finland, Iceland, Denmark, Sweden and Norway – released a joint declaration in 2013 proposing a ban on non-medical circumcision of male minors. In October 2018, the right-wing populist Sweden Democrats party submitted a draft motion to parliament calling for a ban. At the annual conference of the Centre Party in September 2019, 314 to 166 commissioners voted in favor of prohibiting boys' circumcision. Several Jewish and Islamic organisations voiced their opposition to a potential ban. The Left Party has also expressed support for a prohibition on circumcising boys before the age of 18; other parties have so far not backed a potential ban, though the Green Party found the practice 'problematic'. In favour of a ban Sweden Democrats Centre Party Left Party Against a ban Christian Democrats Liberals Moderate Party Swedish Social Democratic Party Green Party (does find circumcision 'problematic') Switzerland According to a July 2012 survey by 20 Minuten involving 8,000 participants, 64% of the Swiss population wanted religious circumcision to be banned. 67% of men and 56% of women were in favour. 93% of Muslim respondents and 75% of Jewish respondents opposed a ban. Over 25% of male respondents were themselves circumcised; 96% of Muslim men and 89% of Jewish men in the survey said they were circumcised, while 20% of circumcised men belonged to neither religion. Almost a third of circumcised men favoured a ban, with 12% wishing in hindsight that they had not been circumcised. United Kingdom Male circumcision has traditionally been presumed to be legal under British law, however some authors have argued that there is no solid foundation for this view in English law. While legal, the British Medical Association finds it ethically unacceptable to circumcise a child or young person, either with or without competence, who refuses the procedure, irrespective of the parents' wishes, and that parental preference alone does not constitute sufficient grounds for performing NTMC on a child unable to express his own view: The passage of the Human Rights Act 1998 has led to some speculation that the lawfulness of the circumcision of male children is unclear. One 1999 case, Re "J" (child's religious upbringing and circumcision) said that circumcision in Britain required the consent of all those with parental responsibility (however this comment was not part of the reason for the judgement and therefore is not legally binding), or the permission of the court, acting for the best interests of the child, and issued an order prohibiting the circumcision of a male child of a non-practicing Muslim father and non-practicing Christian mother with custody. The reasoning included evidence that circumcision carried some medical risk; that the operation would be likely to weaken the relationship of the child with his mother, who strongly objected to circumcision without medical necessity; that the child may be subject to ridicule by his peers as the odd one out and that the operation might irreversibly reduce sexual pleasure, by permanently removing some sensory nerves, even though cosmetic foreskin restoration might be possible. The court did not rule out circumcision against the consent of one parent. It cited a hypothetical case of a Jewish mother and an agnostic father with a number of sons, all of whom, by agreement, had been circumcised as infants in accordance with Jewish laws; the parents then have another son who is born after they have separated; the mother wishes him to be circumcised like his brothers; the father for no good reason, refuses his agreement. In such a case, a decision in favor of circumcision was said to be likely. In 2001 the General Medical Council had found a doctor who had botched circumcision operations guilty of abusing his professional position and that he had acted "inappropriately and irresponsibly", and struck him off the register. A doctor who had referred patients to him, and who had pressured a mother into agreeing to the surgery, was also condemned. He was put on an 18-month period of review and retraining, and was allowed to resume unrestricted practice as a doctor in March 2003, after a committee found that he had complied with conditions it placed on him. According to the Northern Echo, he "told the committee he has now changed his approach to circumcision referrals, accepting that most cases can be treated without the need for surgery". Fox and Thomson (2005) argue that consent cannot be given for non-therapeutic circumcision. They say there is "no compelling legal authority for the common view that circumcision is lawful". In 2005 a Muslim man had his son circumcised against the wishes of the child's mother who was the custodial parent. In 2009 it was reported that a 20-year-old man whose father had him ritually circumcised as a baby is preparing to sue the doctor who circumcised him. This is believed to be the first time a person who was circumcised as an infant has made a claim in the UK. The case is expected to be heard in 2010. In a 2015 case regarding female circumcision, a judge concluded that non-therapeutic circumcision of male children is a "significant harm". In 2016, the Family Court in Exeter ruled that a Muslim father could not have his two sons (aged 6 and 4) circumcised after their mother disagreed. Mrs Justice Roberts declared that the boys should first grow old enough "to the point where each of the boys themselves will make their individual choices once they have the maturity and insight to
hospital care. The parents were ordered to pay 1500 euros in damages to their child. In November 2020, the Finnish Parliament passed a new law on female genital mutilation. An earlier version of the draft law could also have criminalised nonmedical infant circumcision, but due to intense lobbying by several Islamic and Jewish organisations including the Central Council of Finnish Jewish Communities, Milah UK, and the European Jewish Congress, the wording was changed and instead, the law passed in Parliament now states that the issue of circumcision of boys should be 'clarified' in the future. In favour of a ban Social Democratic Party of Finland Finns Party Green League Against a ban Christian Democrats Central Council of Finnish Jewish Communities Germany The German Association of Pediatricians (BVKJ) finds no medical reason for non-therapeutic circumcision and that the AAP (2012) recommendation scientifically unsustainable, and that boys should have the same constitutional legal right to physical integrity as girls: In October 2006, a Turkish national who performed ritual circumcisions on seven boys was convicted of causing dangerous bodily harm by the state court in Düsseldorf. In September 2007, a Frankfurt am Main appeals court found that the circumcision of an 11-year-old boy without his approval was an unlawful personal injury. The boy, whose parents were divorced, was visiting his Muslim father during a vacation when his father forced him to be ritually circumcised. The boy had planned to sue his father for . In May 2012, the Cologne regional appellate court ruled that religious circumcision of male children amounts to bodily injury, and is a criminal offense in the area under its jurisdiction. The decision based on the article "Criminal Relevance of Circumcising Boys. A Contribution to the Limitation of Consent in Cases of Care for the Person of the Child" published by Holm Putzke, a German law professor at the University of Passau. The court arrived at its judgment by application of the human rights provisions of the Basic Law, a section of the Civil Code, and some sections of the Criminal Code to non-therapeutic circumcision of male children. Some observers said it could set a legal precedent that criminalizes the practice. Jewish and Muslim groups were outraged by the ruling, viewing it as trampling on freedom of religion. The German ambassador to Israel, Andreas Michaelis, told Israeli lawmakers that Germany was working to resolve the issue and that it doesn't apply at a national level, but instead only to the local jurisdiction of the court in Cologne. The Council of the Coordination of Muslims in Germany condemned the ruling, stating that it is "a serious attack on religious freedom". Ali Kizilkaya, a spokesman of the council, stated that, "The ruling does not take everything into account, religious practice concerning circumcision of young Muslims and Jews has been carried out over the millennia on a global level." The Roman Catholic archbishop of Aachen, Heinrich Mussinghoff, said that the ruling was "very surprising", and the contradiction between "basic rights on freedom of religion and the well-being of the child brought up by the judges is not convincing in this very case". Hans Ulrich Anke, the head of the Protestant Church in Germany, said the ruling should be appealed since it didn't "sufficiently" consider the religious significance of the rite. A spokesman, Steffen Seibert, for German Chancellor Angela Merkel stated that Jewish and Muslim communities will be free to practice circumcision responsibly, and the government would find a way around the local ban in Cologne. The spokesman stated "For everyone in the government it is absolutely clear that we want to have Jewish and Muslim religious life in Germany. Circumcision carried out in a responsible manner must be possible in this country without punishment." In July 2012, a group of rabbis, imams, and others said that they view the ruling against circumcision "an affront on our basic religious and human rights". The joint statement was signed by leaders of groups including Germany's Turkish-Islamic Union for Religious Affairs, the Islamic Center Brussels, the Rabbinical Centre of Europe, the European Jewish Parliament and the European Jewish Association, who met with members of European Parliament from Germany, Finland, Belgium, Italy, and Poland. European rabbis, who urged Jews to continue circumcision, planned further talks with Muslim and Christian leaders to determine how they can oppose the ban together. The Jewish Hospital of Berlin suspended the practice of male circumcision. On 19 July 2012, a joint resolution of the CDU/CSU, SPD and FDP factions in the Bundestag requesting the executive branch to draft a law permitting circumcision of boys to be performed without unnecessary pain in accordance with best medical practice carried with a broad majority. The New York Times reported that the German Medical Association "condemned the ruling for potentially putting children at risk by taking the procedure out of the hands of doctors, but it also warned surgeons note to perform circumcisions for religious reasons until legal clarity was established". The ruling was supported by Deutsche Kinderhilfe, a German child rights organization, which asked for a two-year moratorium to discuss the issue and pointed out that religious circumcision may contravene the Convention on the Rights of the Child (Article 24.3: "States Parties shall take all effective and appropriate measures with a view to abolishing traditional practices prejudicial to the health of children."). The German Academy for Pediatric and Adolescent Medicine (Deutsche Akademie für Kinder- und Jugendmedizin e.V., DAKJ), the German Association for Pediatric Surgery (Deutsche Gesellschaft für Kinderchirurgie, DGKCH) and the Professional Association of Pediatric and Adolescent Physicians (Berufsverband der Kinder- und Jugendärzte) took a firm stand against non-medical routine infant circumcision. In July, in Berlin, a criminal complaint was lodged against Rabbi Yitshak Ehrenberg for "causing bodily harm" by performing religious circumcision, and for vocal support of the continuation of the practice. In September, the prosecutors dismissed the complaint, concluding that "there is no proof to establish that the rabbi's conduct met the 'condition of a criminal' violation". In September, Reuters reported "Berlin's senate said doctors could legally circumcise infant boys for religious reasons in its region, given certain conditions." On 12 December 2012, following a series of hearings and consultations, the Bundestag adopted the proposed law explicitly permitting non-therapeutic circumcision to be performed under certain conditions; it is now §1631(d) in the German Civil Code. The vote tally was 434 ayes, 100 noes, and 46 abstentions. Following approval by the Bundesrat and signing by the Bundespräsident, the new law became effective on 28 December 2012 a day after its publication in the Federal Gazette. Iceland In May 2005, Iceland amended its General Penal Code to criminalise female genital mutilation In February 2018, the Progressive Party proposed a bill that would change the words "girl child" to "child" and "her sexual organs" to "[their] sexual organs", thereby making Iceland the first European country to ban male circumcision for non-medical reasons. The bill discussed in the Alþing, the Icelandic parliament, claimed the practice harmed the physical integrity of young boys, was often performed without anaesthesia and in an unhygienic manner by religious leaders instead of medical experts. These facts were deemed incompatible with the United Nations Convention on the Rights of the Child (1990). Critics argued the bill infringed on religious freedom or constituted antisemitism or anti-Muslim bigotry, making it hard for Muslims and Jews to live there. Silja Dögg Gunnarsdóttir, who proposed the ban, retorted that Iceland had already prohibited female circumcision in 2005, and "If we have laws banning circumcision for girls, then we should do so for boys." On 29 April, the bill was sent back to Parliament for revisions. On 25 March 2018, members of Jews Against Circumcision spoke in the Alþing expressing their support for the proposed ban, dismissing claims that it was motivated by antisemitism, anti-Muslim bigotry, xenophobia or anti-immigration sentiment. The law was put on hold in 2018 following pressure from the United States, Israel, and various lobbyist groups.

The judge directed the jury not to "bring what he called their white western values to bear when they were deciding this case" and effectively imposed a not guilty verdict on the jury. After deliberating for an hour and a half they found the defendant not guilty. Israel In Israel, Jewish circumcision is entirely legal. The circumcision rate is very high in Israel, although some limited data suggests the practice is slowly declining. According to an online survey by the parents' portal Mamy in 2006, the rate was 95%, while earlier estimates put it at 98–99%. Ben Shalem, an organisation dedicated to the abolition of circumcision, petitioned the Supreme Court in 1999 on the grounds that circumcision violated human dignity, children's rights and criminal law. The petition was rejected. In 2013, a Rabbinical court in Israel ordered a mother in the midst of divorce proceedings to circumcise her son in accordance with the father's wishes, or pay a fine of 500 Israeli Shekel for every day that the child is not circumcised. She appealed against the Rabbinical court ruling and the High Court ruled in her favour stating, among other considerations, the basic right of freedom from religion. Netherlands The Royal Dutch Medical Association (KNMG) finds non-therapeutic circumcision of male minors to be in conflict with children's right to autonomy and physical integrity, and that there are good reasons for its legal prohibition, as exists for female genital mutilation: In May 2008 a father who had his two sons, aged 3 and 6 circumcised against the will of their mother was found not guilty of abuse as the circumcision was performed by a physician and due to the court's restraint in setting a legal precedent; instead he was given a 6-week suspended jail sentence for taking the boys away from their mother against her will. The parquet of the Supreme Court of the Netherlands made an elaborate statement on the legal status of circumcision on 5 July 2011 in the course of a criminal case. First, the parquet notes that there is no law that specifically prohibits the circumcision of boys, nor that the practice falls under the more general crime of (zware) mishandeling ('(grave) assault'). 'Genital mutilation of girls in any case undoubtedly falls under (zware) mishandeling (Art. 300–303 Dutch Criminal Code). Whereas most forms of genital cutting of girls are generally marked as genital mutilation, a similar communis opinio regarding genital cutting of boys does not yet exist so far.' The Supreme Court acknowledged that society's attitudes on genital cutting of boys had been gradually shifting over the course of years, and that 'the increasing concern [in the medical world] about the harm and the risk of complications during a circumcision is indeed relevant', but that overall there were not enough reasons yet to proceed to criminalisation. Neither could intentional infliction of grave bodily harm (Art. 82 Dutch Criminal Code) be applied to the normal circumstances of a competently and hygienically performed circumcision in a clinic. And because young children are incapable of exercising the right to self-determination, parents ought to do this on their behalf. They can both request a circumcision to be performed, as well as consent to it being performed, on the grounds of their parental authority. However, it is important that both parents consent to the procedure.

and the Evangelical Lutheran Church in America (ELCA) in the United States, establishing full communion between them. It was ratified by the ELCA in 1999, the ECUSA in 2000, after the narrow failure of a previous agreement. Its principal author on the Episcopal side was theological professor J. Robert Wright. Under the agreement, they recognize the validity of each other's baptisms and ordinations. The agreement provided that the ELCA would accept the historical episcopate and the "threefold ministry" of bishop - priest (or pastor) - deacon with respect to ministers of communicant churches serving ELCA congregations; the installation of the ELCA presiding bishop was performed through the laying on of hands by Luthearn bishops in the historic episcopate. This provision was opposed by some in the ELCA, which after its founding merger in 1988, held a lengthy study of the ministry which was undertaken with divided opinions. In response to concerns about the meaning of the CCM, synod bishops in the ELCA drafted the Tucson resolution which presented the official ELCA position. It made clear that there is no requirement to ordain deacons or accept their ministry. It also provided assurance that the ELCA did not and was not required by CCM to change its own theological stance.

The traditional ELCA doctrine is affirmed by the Tucson resolution. Others objected on the grounds that adopting the Episcopalian / Anglican view on priestly orders and hierarchical structure was contrary to the Evangelical Lutheran concept of the "priesthood of all believers", which holds that all Christians stand on equal footing before God. They argued that the Old Covenant required a priest to mediate between God and humanity, but that New Covenant explicitly abolishes the need for priestly role by making every Christian a

This could be anything like a website or to configure your phone to connect to Wi-Fi. See image. On some user interfaces, context menu items are accompanied by icons for quicker recognition upon navigation. Context menus can also have a top row of icons only for quick access to most frequently used options. Windows mouse click behavior is such that the context menu doesn't open while the mouse button is pressed, but only opens the menu when the button is released, so the user has to click again to select a context menu item. This behavior differs from that of macOS and most free software GUIs. In Microsoft Windows, pressing the Application key or Shift+F10 opens a context menu for the region that has focus. Context menus are sometimes hierarchically organized, allowing navigation through different levels of the menu structure. The implementations differ: Microsoft Word was one of the first applications to only show sub-entries of some menu entries after clicking an arrow icon on the context menu, otherwise executing an action associated with the parent entry. This makes it possible to quickly repeat an action with the parameters of the previous execution, and to better separate options from actions. X Window
state, or context, of the operating system or application to which the menu belongs. Usually the available choices are actions related to the selected object. From a technical point of view, such a context menu is a graphical control element. History Context menus first appeared in the Smalltalk environment on the Xerox Alto computer, where they were called pop-up menus; they were invented by Dan Ingalls in the mid-1970s. Microsoft Office v3.0 introduced the context menu for copy and paste functionality in 1990. Borland demonstrated extensive use of the context menu in 1991 at the Second Paradox Conference in Phoenix Arizona. Lotus 1-2-3/G for OS/2 v1.0 added additional formatting options in 1991. Borland Quattro Pro for Windows v1.0 introduced the Properties context menu option in 1992. Implementation Context menus are opened via various forms of user interaction that target a region of the GUI that supports context menus. The specific form of user interaction and the means by which a region is targeted vary: On a computer running Microsoft Windows, macOS, or Unix running the X Window System, clicking the secondary mouse button (usually the right button) opens a context menu for the region that is under the mouse pointer. For quickness, implementations may additionally support hold-and-release selection, meaning the pointer is held down and dragged, and released at desirable menu entry. On systems that support one-button mice, context menus are typically opened by pressing and holding the primary mouse button (this works on the icons in the Dock on macOS) or by pressing a keyboard/mouse button combination (e.g. Ctrl-mouse click in Classic Mac OS and macOS). A keyboard alternative for macOS is to enable Mouse keys in Universal Access. Then, depending on whether a laptop or compact or extended keyboard type is used,
achieve a high level of spiritually, similar to an angel, although his soul is still fundamentally different in character, but not value, from a Jewish one. Tzemach Tzedek, the third rebbe of Chabad, wrote that the Muslims are naturally good-hearted people. Rabbi Yosef Jacobson, a popular contemporary Chabad lecturer, teaches that in today's world most non-Jews belong to the category of righteous Gentiles, effectively rendering the Tanya's attitude anachronistic. Altruism An anti-Zionist interpretation of Tanya was offered by Abraham Yehudah Khein, a prominent Ukrainian Chabad rabbi, who supported anarchist communism and considered Peter Kropotkin a great Tzaddik. Khein basically read the Tanya backwards; since the souls of idol worshipers are known to be evil, according to the Tanya, while the Jewish souls are known to be good, he concluded that truly altruistic people are really Jewish, in a spiritual sense, while Jewish nationalists and class oppressors are not. By this logic, he claimed that Vladimir Solovyov and Rabindranath Tagore probably have Jewish souls, while Leon Trotsky and other totalitarians do not, and many Zionists, whom he compared to apes, are merely "Jewish by birth certificate". Righteous non-Jews Nachman of Breslov also believed that Jewishness is a level of consciousness, and not an intrinsic inborn quality. He wrote that, according to the Book of Malachi, one can find "potential Jews" among all nations, whose souls are illuminated by the leap of "holy faith", which "activated" the Jewishness in their souls. These people would otherwise convert to Judaism, but prefer not to do so. Instead, they recognize the Divine unity within their pagan religions. Isaac Arama, an influential philosopher and mystic of the 15th century, believed that righteous non-Jews are spiritually identical to the righteous Jews. Rabbi Menachem Meiri, a famous Catalan Talmudic commentator and Maimonidian philosopher, considered all people, who sincerely profess an ethical religion, to be part of a greater "spiritual Israel". He explicitly included Christians and Muslims in this category. Meiri rejected all Talmudic laws that discriminate between the Jews and non-Jews, claiming that they only apply to the ancient idolators, who had no sense of morality. The only exceptions are a few laws related directly or indirectly to intermarriage, which Meiri did recognize. Meiri applied his idea of "spiritual Israel" to the Talmudic statements about unique qualities of the Jewish people. For example, he believed that the famous saying that Israel is above astrological predestination (Ein Mazal le-Israel) also applied to the followers of other ethical faiths. He also considered countries, inhabited by decent moral non-Jews, such as Languedoc, as a spiritual part of the Holy Land. Spinoza One Jewish critic of chosenness was the philosopher Baruch Spinoza. In the third chapter of his Theologico-Political Treatise, Spinoza mounts an argument against a naive interpretation of God's choice of the Jews. Bringing evidence from the Bible itself, he argues that God's choice of Israel was not unique (he had chosen other nations before choosing the Hebrew nation) and that the choice of the Jews is neither inclusive (it does not include all of the Jews, but only the 'pious' ones) nor exclusive (it also includes 'true gentile prophets'). Finally, he argues that God's choice is not unconditional. Recalling the numerous times God threatened the complete destruction of the Hebrew nation, he asserts that this choice is neither absolute, nor eternal, nor necessary. Reconstructionist criticism Reconstructionist Judaism rejects the concept of chosenness. Its founder, Rabbi Mordecai Kaplan, said that the idea that God chose the Jewish people leads to racist beliefs among Jews, and thus must be excised from Jewish theology. This rejection of chosenness is made explicit in the movement's siddurim (prayer books). For example, the original blessing recited before reading from the Torah contains the phrase, "asher bahar banu mikol ha’amim"—"Praised are you Lord our God, ruler of the Universe, who has chosen us from among all peoples by giving us the Torah." The Reconstructionist version is rewritten as "asher kervanu la’avodato", "Praised are you Lord our God, ruler of the Universe, who has drawn us to your service by giving us the Torah." In the mid-1980s, the Reconstructionist movement issued its Platform on Reconstructionism. It states that the idea of chosenness is "morally untenable", because anyone who has such beliefs "implies the superiority of the elect community and the rejection of others." Not all Reconstructionists accept this view. The newest siddur of the movement, Kol Haneshamah, includes the traditional blessings as an option, and some modern Reconstructionist writers have opined that the traditional formulation is not racist, and should be embraced. An original prayer book by Reconstructionist feminist poet Marcia Falk, The Book of Blessings, has been widely accepted by both Reform and Reconstructionist Jews. Falk rejects all concepts relating to hierarchy or distinction; she sees any distinction as leading to the acceptance of other kinds of distinctions, thus leading to prejudice. She writes that as a politically liberal feminist, she must reject distinctions made between men and women, homosexuals and heterosexuals, Jews and non-Jews, and to some extent even distinctions between the Sabbath and the other six days of the week. She thus rejects the idea of chosenness as unethical. She also rejects Jewish theology in general, and instead holds to a form of religious humanism. Falk writes: "The idea of Israel as God's chosen people ... is a key concept in rabbinic Judaism. Yet it is particularly problematic for many Jews today, in that it seems to fly in the face of monotheistic belief that all humanity is created in the divine image—and hence, all humanity is equally loved and valued by God. ... I find it difficult to conceive of a feminist Judaism that would incorporate it in its teaching: the valuing of one people over and above others is all too analogous to the privileging of one sex over another." Reconstructionist author Judith Plaskow also criticises the idea of chosenness, for many of the same reasons as Falk. A politically liberal lesbian, Plaskow rejects most distinctions made between men and women, homosexuals and heterosexuals, and Jews and non-Jews. In contrast to Falk, Plaskow does not reject all concepts of difference as inherently leading to unethical beliefs, and holds to a more classical form of Jewish theism than Falk. A number of responses to these views have been made by Reform and Conservative Jews; they hold that these criticisms are against teachings that do not exist within liberal forms of Judaism, and which are rare in Orthodox Judaism (outside certain Haredi communities, such as Chabad). A separate criticism stems from the very existence of feminist forms of Judaism in all denominations of Judaism, which do not have a problem with the concepts of chosenness. Views of other religions Islam The children of Israel enjoy a special status in the Islamic book, the Quran (2:47 and 2:122). However, Muslim scholars point out that this status did not confer upon Israelites any racial superiority, and was only valid so long as the Israelites maintain their covenant with God. Christianity Some Christians believe that the Jews were God's chosen people, but because of Jewish Rejection of Jesus, the Christians in turn received that special status. This doctrine is known as Supersessionism. Other Christians, such as the Christadelphians, believe that God has not rejected Israel as his chosen people and that the Jews will in fact accept Jesus as their Messiah at his Second Coming, resulting in their salvation. Augustine criticized Jewish chosenness as "carnal." He reasoned that Israel was chosen "according to the flesh." Influence on Judaism's relationship with other religions Avi Beker, an Israeli scholar and former Secretary General of the World Jewish Congress, regarded the idea of the chosen people as Judaism's defining concept and "the central unspoken psychological, historical, and theological problem which is
among the nations "as the lily among thorns", or "as wheat among the chaff." Modern Orthodox views Rabbi Lord Immanuel Jakobovits, former Chief Rabbi of the United Synagogue of Great Britain (Modern Orthodox Judaism), described chosenness in this way: "Yes, I do believe that the chosen people concept as affirmed by Judaism in its holy writ, its prayers, and its millennial tradition. In fact, I believe that every people—and indeed, in a more limited way, every individual—is "chosen" or destined for some distinct purpose in advancing the designs of Providence. Only, some fulfill their mission and others do not. Maybe the Greeks were chosen for their unique contributions to art and philosophy, the Romans for their pioneering services in law and government, the British for bringing parliamentary rule into the world, and the Americans for piloting democracy in a pluralistic society. The Jews were chosen by God to be 'peculiar unto Me' as the pioneers of religion and morality; that was and is their national purpose." Modern Orthodox theologian Michael Wyschogrod wrote: "[T]he initial election of Abraham himself was not earned. ... We are simply told that God commanded Abraham to leave his place of birth and go to a land that God would show him. He is also promised that his descendants will become a numerous people. But nowhere does the Bible tell us why Abraham rather than someone else was chosen. The implication is that God chooses whom He wishes and that He owes no accounting to anyone for His choices." Rabbi Norman Lamm, a leader of Modern Orthodox Judaism, wrote: "The chosenness of Israel relates exclusively to its spiritual vocation embodied in the Torah; the doctrine, indeed, was announced at Sinai. Whenever it is mentioned in our liturgy—such as the blessing immediately preceding the Shema....it is always related to Torah or Mitzvot (commandments). This spiritual vocation consists of two complementary functions, described as "Goy Kadosh", that of a holy nation, and "Mamlekhet Kohanim", that of a kingdom of priests. The first term denotes the development of communal separateness or differences in order to achieve a collective self-transcendence. ... The second term implies the obligation of this brotherhood of the spiritual elite toward the rest of mankind; priesthood is defined by the prophets as fundamentally a teaching vocation." Conservative views Conservative Judaism views the concept of chosenness in this way: "Few beliefs have been subject to as much misunderstanding as the 'Chosen People' doctrine. The Torah and the Prophets clearly stated that this does not imply any innate Jewish superiority. In the words of Amos (3:2) 'You alone have I singled out of all the families of the earth—that is why I will call you to account for your iniquities.' The Torah tells us that we are to be "a kingdom of priests and a holy nation" with obligations and duties which flowed from our willingness to accept this status. Far from being a license for special privilege, it entailed additional responsibilities not only toward God but to our fellow human beings. As expressed in the blessing at the reading of the Torah, our people have always felt it to be a privilege to be selected for such a purpose. For the modern traditional Jew, the doctrine of the election and the covenant of Israel offers a purpose for Jewish existence which transcends its own self interests. It suggests that because of our special history and unique heritage we are in a position to demonstrate that a people that takes seriously the idea of being covenanted with God can not only thrive in the face of oppression, but can be a source of blessing to its children and its neighbors. It obligates us to build a just and compassionate society throughout the world and especially in the land of Israel where we may teach by example what it means to be a 'covenant people, a light unto the nations.'" Rabbi Reuven Hammer comments on the excised sentence in the Aleinu prayer mentioned above: "Originally the text read that God has not made us like the nations who "bow down to nothingness and vanity, and pray to an impotent god", ... In the Middle Ages these words were censored, since the church believed they were an insult to Christianity. Omitting them tends to give the impression that the Aleinu teaches that we are both different and better than others. The actual intent is to say that we are thankful that God has enlightened us so that, unlike the pagans, we worship the true God and not idols. There is no inherent superiority in being Jewish, but we do assert the superiority of monotheistic belief over paganism. Although paganism still exists today, we are no longer the only ones to have a belief in one God." Reform views Reform Judaism views the concept of chosenness as follows: "Throughout the ages it has been Israel's mission to witness to the Divine in the face of every form of paganism and materialism. We regard it as our historic task to cooperate with all men in the establishment of the kingdom of God, of universal brotherhood, Justice, truth and peace on earth. This is our Messianic goal." In 1999 the Reform movement stated, "We affirm that the Jewish people are bound to God by an eternal covenant, as reflected in our varied understandings of Creation, Revelation and Redemption. ... We are Israel, a people aspiring to holiness, singled out through our ancient covenant and our unique history among the nations to be witnesses to God's presence. We are linked by that covenant and that history to all Jews in every age and place." Alternative views Equality of souls Many Kabbalistic sources, notably the Tanya, contain statements to the effect that the Jewish soul is qualitatively different from the non-Jewish soul. A number of known Chabad rabbis offered alternative readings of the Tanya, did not take this teaching literally, and even managed to reconcile it with the leftist ideas of internationalism and class struggle. The original text of the Tanya refers to the "idol worshippers" and does not mention the "nations of the world" at all, although such interpretation was endorsed by Menachem Mendel Schneerson and is popular in contemporary Chabad circles. Hillel of Parich, an early Tanya commentator, wrote that the souls of righteous Gentiles are more similar to the Jewish souls, and are generally good and not egoistic. This teaching was accepted by Schneerson and is considered normative in Chabad. Different in character but not different in value According to the author of the Tanya himself, a righteous non-Jew can achieve a high level of spiritually, similar to an angel, although his soul is still fundamentally different in character, but not value, from a Jewish one. Tzemach Tzedek, the third rebbe of Chabad, wrote that the Muslims are naturally good-hearted people. Rabbi Yosef Jacobson, a popular contemporary Chabad lecturer, teaches that in today's world most non-Jews belong to the category of righteous Gentiles, effectively rendering the Tanya's attitude anachronistic.

by exhausting their energy reserves below-ground. Today, frequent accidental ignitions can convert chaparral from a native shrubland to non-native annual grassland and drastically reduce species diversity, especially under drought brought about by climate change. Wildfire debate There are two older hypotheses relating to California chaparral fire regimes that caused considerable debate within the fields of wildfire ecology and land management. Research over the past two decades have rejected these hypotheses: That older stands of chaparral become "senescent" or "decadent", thus implying that fire is necessary for the plants to remain healthy, That wildfire suppression policies have allowed dead chaparral to accumulate unnaturally, creating ample fuel for large fires. The perspective that older chaparral is unhealthy or unproductive may have originated during the 1940s when studies were conducted measuring the amount of forage available to deer populations in chaparral stands. However, according to recent studies, California chaparral is extraordinarily resilient to very long periods without fire and continues to maintain productive growth throughout pre-fire conditions. Seeds of many chaparral plants actually require 30 years or more worth of accumulated leaf litter before they will successfully germinate (e.g., scrub oak, Quercus berberidifolia; toyon, Heteromeles arbutifolia; and holly-leafed cherry, Prunus ilicifolia''). When intervals between fires drop below 10 to 15 years, many chaparral species are eliminated and the system is typically replaced by non-native, invasive, weedy grassland. The idea that older chaparral is responsible for causing large fires was originally proposed in the 1980s by comparing wildfires in Baja California and southern California. It was suggested that fire suppression activities in southern California allowed more fuel to accumulate, which in turn led to larger fires. This is similar to the observation that fire suppression and other human-caused disturbances in dry, ponderosa pine forests in the Southwest of the United States has unnaturally increased forest density. Historically, mixed-severity fires likely burned through these forests every decade or so, burning understory plants, small trees, and downed logs at low-severity, and patches of trees at high-severity. However, chaparral has a crown-fire regime, meaning that fires consume nearly all the above ground growth whenever they burn, with a historical frequency of 30 to 150 years or more. A detailed analysis of historical fire data concluded that fire suppression activities have been ineffective at excluding fire from southern California chaparral, unlike in ponderosa pine forests. In addition, the number of fires is increasing in step with population growth and exacerbated by human-caused climate change. Chaparral stand age does not have a significant correlation to its tendency to burn. Large, high-intensity wildfires are part of the natural fire regime for California chaparral. Extreme weather conditions (low humidity, high temperature, high winds), drought, and low fuel moisture are the primary factors in determining how large a chaparral fire becomes.

on the coastal side of the mountains, which experiences higher winter rainfall. Naturally, desert chaparral experiences less winter rainfall than cismontane chaparral. Plants in this community are characterized by small, hard (sclerophyllic) evergreen (non-deciduous) leaves. Desert chaparral grows above California's desert cactus scrub plant community and below the pinyon-juniper woodland. It is further distinguished from the deciduous sub-alpine scrub above the pinyon-juniper woodlands on the same side of the Peninsular ranges. Due to the lower annual rainfall (resulting in slower plant growth rates) when compared to cismontane chaparral, desert chaparral is more vulnerable to biodiversity loss and the invasion of non-native weeds and grasses if disturbed by human activity and frequent fire. Transmontane chaparral distribution Transmontane (desert) chaparral typically grows on the lower ( elevation) northern slopes of the southern Transverse Ranges (running east to west in San Bernardino and Los Angeles counties) and on the lower () eastern slopes of the Peninsular Ranges (running south to north from lower Baja California to Riverside and Orange counties and the Transverse Ranges). It can also be found in higher-elevation sky islands in the interior of the deserts, such as in the upper New York Mountains within the Mojave National Preserve in the Mojave Desert. The California transmontane (desert) chaparral is found in the rain shadow deserts of the following: Sierra Nevada creating the Great Basin Desert and northern Mojave Desert Transverse ranges creating the western through eastern Mojave Desert Peninsular ranges creating the Colorado Desert and Yuha Desert. Transmontane chaparral plants Adenostoma fasciculatum, chamise (a low shrub common to most chaparral with clusters of tiny needle like leaves or fascicles; similar in appearance to coastal Eriogonum fasciculatum) Agave deserti, desert agave Arctostaphylos glauca, bigberry manzanita (smooth red bark with large edible berries; glauca means blue-green, the color of its leaves) Ceanothus greggii, desert ceanothus, California lilac (a nitrogen fixer, has hair on both sides of leaves for heat dissipation) Cercocarpus ledifolius, curl leaf mountain mahogany, a nitrogen fixer important food source for desert bighorn sheep Dendromecon rigida, bush poppy (a fire follower with four petaled yellow flowers) Ephedra spp., Mormon teas Fremontodendron californicum, California flannel bush (lobed leaves with fine coating of hair, covered with yellow blossoms in spring) Opuntia acanthocarpa, buckhorn cholla (branches resemble antlers of a deer) Opuntia echinocarpa, silver or golden cholla (depending on color of the spines) Opuntia phaeacantha, desert prickly pear (fruit is important food source for animals) Purshia tridentata, buckbrush, antelope bitterbrush (Rosaceae family) Prunus fremontii, desert apricot Prunus fasciculata, desert almond (commonly infested with tent caterpillars of Malacosoma spp.) Prunus ilicifolia, holly leaved cherry Quercus cornelius-mulleri, desert scrub oak or Muller's oak Rhus ovata, sugar bush Simmondsia chinensis, jojoba Yucca schidigera, Mojave yucca Hesperoyucca whipplei (syn. Yucca whipplei), foothill yucca – our lord's candle. Transmontane chaparral animals There is overlap of animals with those of the adjacent desert and pinyon-juniper communities. Canis latrans, coyote Lynx rufus, bobcat Neotoma sp., desert pack rat Odocoileus hemionus, mule deer Peromyscus truei, pinyon mouse Puma concolor, mountain lion Stagmomantis californica, California mantis Fire Chaparral is a coastal biome with hot, dry summers and mild, rainy winters. The chaparral area receives about of precipitation a year. This makes the chaparral most vulnerable to fire in the late summer and fall. The chaparral ecosystem as a whole is adapted to be able to recover from naturally infrequent fire (fires occurring a minimum of 30 years apart); indeed, chaparral regions are known culturally and historically for their impressive fires. (This does create a conflict with human development adjacent to and expanding into chaparral systems.) Additionally, Native Americans burned chaparral near villages on the coastal plain to promote grasslands for textiles and food. Before a major fire, typical chaparral plant communities are dominated by manzanita, chamise Adenostoma fasciculatum and Ceanothus species, toyon (which can sometimes be interspersed with scrub oaks), and other drought-resistant shrubs with hard (sclerophyllous) leaves; these plants resprout (see resprouter) from underground burls after a fire. Plants that are long-lived in the seed bank or serotinous with induced germination after fire include chamise, Ceanothus, and fiddleneck. Some chaparral plant communities may grow so dense and tall that it becomes difficult for large animals and humans to penetrate, but may be teeming with smaller fauna in the understory. The seeds of many chaparral plant species are stimulated to germinate by some fire cue (heat or the chemicals from smoke or charred wood). During the time shortly after a fire, chaparral communities may contain soft-leaved herbaceous, fire following annual wildflowers and short-lived perennials that dominate the community for the first few years – until the burl resprouts and seedlings of chaparral shrub species create a mature, dense overstory. Seeds of annuals and shrubs lie dormant until the next fire creates the conditions needed for germination. Several shrub species such as Ceanothus fix nitrogen, increasing the availability nitrogen compounds in the soil. Because of the hot, dry conditions that exist in the California summer and fall, chaparral is one of the most fire-prone plant communities in North America. Some fires are caused by lightning, but these are usually during periods of high humidity and low winds and are easily controlled. Nearly all of the very large wildfires are caused by human activity during periods of hot, dry easterly Santa Ana winds. These man-made fires are commonly caused by power line failures, vehicle fires and collisions, sparks from machinery, arson, or campfires. Threatened by high fire frequency Though adapted to infrequent fires, chaparral plant communities can be eliminated by frequent fires. A high frequency of fire (less than ten years) will result in the loss of obligate seeding shrub species such as Manzanita spp. This high frequency disallows seeder plants to reach their reproductive size before the next fire and the community shifts to a sprouter-dominance. If high frequency fires continue over time, obligate resprouting shrub species can also be eliminated by exhausting their energy reserves below-ground. Today, frequent accidental ignitions can convert chaparral from a native shrubland to non-native annual grassland and drastically reduce species diversity, especially under drought brought about by climate change. Wildfire debate There are two older hypotheses relating to California chaparral fire regimes that caused considerable debate within the fields of wildfire ecology and land management. Research over the past two decades have rejected these hypotheses: That older stands of chaparral become "senescent" or "decadent", thus implying that fire is necessary for the plants to remain healthy, That wildfire suppression policies have allowed dead chaparral to accumulate unnaturally, creating ample fuel for large fires. The perspective that older chaparral is unhealthy or unproductive may have originated during the 1940s when studies were conducted measuring the amount of forage available to deer populations in chaparral stands. However, according to recent studies, California chaparral is extraordinarily resilient to very long periods without fire and continues to maintain productive growth throughout pre-fire conditions. Seeds of many chaparral plants actually require 30 years or more worth of accumulated leaf litter before they will successfully germinate (e.g., scrub oak, Quercus berberidifolia; toyon, Heteromeles arbutifolia; and holly-leafed cherry, Prunus ilicifolia''). When intervals between fires drop below 10 to 15 years, many chaparral species are eliminated and the system is typically replaced by non-native, invasive, weedy grassland. The idea that older chaparral is responsible for causing large fires was originally proposed in the 1980s by comparing wildfires in Baja California and southern California. It was suggested that fire suppression activities in southern California allowed more fuel to accumulate, which in turn led to larger fires. This is similar to the observation that fire suppression and other human-caused disturbances in dry, ponderosa pine forests in the Southwest of the United States has unnaturally increased forest density. Historically, mixed-severity fires likely burned through these forests every decade or so, burning understory plants, small trees, and downed logs at low-severity, and patches of trees at high-severity. However, chaparral has a crown-fire regime, meaning that fires consume nearly all the above ground growth whenever they burn, with a historical frequency of 30 to 150 years or more. A detailed analysis of historical fire data concluded that fire suppression activities have been ineffective at excluding fire from southern California chaparral, unlike in ponderosa pine forests.

Marque and Reprisal, when the type—exemplified by Chasseur, launched at Fells Point, Baltimore in 1814—became known for her incredible speed; the deep draft enabled the Baltimore clipper to sail close to the wind. Clippers, running the British blockade of Baltimore, came to be recognized for speed rather than cargo space. The type existed as early as 1780. A 1789 drawing of —purchased by the Royal Navy in 1780 in the West Indies—represents the earliest draught of what became known as the Baltimore Clipper Speed was also required for the opium trade from India to China. The fast-sailing vessels used were called Opium Clippers. Some of these were built specifically for the purposemostly in India and Britain. Some fruit schooners were bought for this trade, as were some Baltimore clippers. Vessels of the Baltimore clipper type continued to be built for the slave trade, being useful for escaping enforcement of the British and American legislation prohibiting the trans-atlantic slave trade. Some of these Baltimore clippers were captured when working as slavers, condemned by the appropriate court, and sold to owners who then used them as opium clippersmoving from one illegal international trade to another. Ann McKim, built in Baltimore in 1833 by the Kennard & Williamson shipyard, is considered by some to be the original clipper ship. (Maritime historians Howard I. Chapelle and David MacGregor decry the concept of the "first" clipper, preferring a more evolutionary, multi-stepped development of the type.) She measured 494 tons OM, and was built on the enlarged lines of a Baltimore clipper, with sharply raked stem, counter stern and square rig. Although Ann McKim was the first large clipper ship ever constructed, it cannot be said that she founded the clipper ship era, or even that she directly influenced shipbuilders, since no other ship was built like her; but she may have suggested the clipper design in vessels of ship rig. She did, however, influence the building of Rainbow in 1845, the first extreme clipper ship. In Aberdeen, Scotland, the shipbuilders Alexander Hall and Sons developed the "Aberdeen" clipper bow in the late 1830s: the first was Scottish Maid launched in 1839. Scottish Maid, 150 tons OM, was the first British clipper ship. "Scottish Maid was intended for the Aberdeen-London trade, where speed was crucial to compete with steamships. The Hall brothers tested various hulls in a water tank and found the clipper design most effective. The design was influenced by tonnage regulations. Tonnage measured a ship's cargo capacity and was used to calculate tax and harbour dues. The new 1836 regulations measured depth and breadth with length measured at half midship depth. Extra length above this level was tax-free and became a feature of clippers. Scottish Maid proved swift and reliable and the design was widely copied." The earliest British clipper ships were built for trade within the British Isles (Scottish Maid was built for the Aberdeen to London trade). Then followed the vast clipper trade of tea, opium, spices and other goods from the Far East to Europe, and the ships became known as "tea clippers". From 1839, larger American clipper ships started to be built beginning with Akbar, 650 tons OM, in 1839, and including the 1844-built Houqua, 581 tons OM. These larger vessels were built predominantly for use in the China tea trade and known as "tea clippers". Smaller clipper vessels also continued to be built predominantly for the China opium trade and known as "opium clippers" such as the 1842-built Ariel, 100 tons OM. Then in 1845 Rainbow, 757 tons OM, the first extreme clipper was launched in New York. These American clippers were larger vessels designed to sacrifice cargo capacity for speed. They had a bow lengthened above the water, a drawing out and sharpening of the forward body, and the greatest breadth further aft. Extreme clippers were built in the period 1845 to 1855. In 1851, shipbuilders in Medford, Massachusetts built the Antelope, often called the Antelope of Boston to distinguish her from other ships of the same name. This vessel is sometimes called one of the first medium clipper ships. A ship-design journalist noted that "the design of her model was to combine large stowage capacity with good sailing qualities." The Antelope was relatively flat-floored and had only an 8-inch dead rise at half-floor. The medium clipper, though still very fast, could carry more cargo. After 1854 extreme clippers were replaced in American shipbuilding yards by medium clippers. The Flying Cloud was a clipper ship that claimed the fastest passage between New York and San Francisco, 89 days 8 hours. (The other contender for this "blue ribbon" title was the medium clipper Andrew Jackson—there is an unresolvable argument over timing these voyages "from pilot to pilot"). Flying Cloud was the most famous of the clippers built by Donald McKay. She was known for her extremely close race with the Hornet in 1853; for having a woman navigator, Eleanor Creesy, wife of Josiah Perkins Creesy, who skippered the Flying Cloud on two record-setting voyages from New York to San Francisco; and for sailing in the Australia and timber trades. Clipper ships largely ceased being built in American shipyards in 1859 when, unlike the earlier boom years, only four clipper ships were built; a few were built in the 1860s. The last American clipper ship was "the Pilgrim" launched in 1873 from the shipyards of Medford, Massachusetts, built by Joshua T. Foster. Among shipowners of the day, "Medford-built" came to mean the best. British clipper ships continued to be built after 1859. From 1859 a new design was developed for British clipper ships that was nothing like the American clippers; these ships continued to be called extreme clippers. The new design had a sleek graceful appearance, less sheer, less freeboard, lower bulwarks, and smaller breadth. They were built for the China tea trade, starting with Falcon in 1859, and continuing until 1870. The earlier ships were made from wood, though some were made from iron, just as some British clippers had been made from iron prior to 1859. In 1863 the first tea clippers of composite construction were brought out, combining the best of both worlds. Composite clippers had the strength of iron spars with wooden hulls, and copper sheathing could be added to prevent the fouling that occurred on iron hulls. After 1869, with the opening of the Suez Canal that greatly advantaged steam vessels (see Decline below), the tea trade collapsed for clippers. From the late 1860s until the early 1870s the clipper trade increasingly focused on the Britain to Australia and New Zealand route, carrying goods and immigrants, services that had begun earlier with the Australian Gold Rush of the 1850s. British-built clipper ships and many American-built British-owned ships were used. Even in the 1880s, sailing ships were still the main carriers of cargoes between Britain, and Australia and New Zealand. This trade eventually became unprofitable, and the ageing clipper fleet became unseaworthy. China clippers and the apogee of sail Among the most notable clippers were the China clippers, also called tea clippers or opium clippers, designed to ply the trade routes between Europe and the East Indies. The last example of these still in reasonable condition is Cutty Sark, preserved in dry dock at Greenwich, United Kingdom. Damaged by fire on 21 May 2007 while undergoing conservation, the ship was permanently elevated three metres above the dry dock floor in 2010 as part of a plan for long-term preservation. Before the early 18th century, the East India Company paid for its tea mainly in silver. When the Chinese Emperor chose to embargo European manufactured commodities and demand payment for all Chinese goods in silver, the price rose, restricting trade. The East India Company began to produce something desired by the Chinese as much as tea was by the British: opium. This had a significant influence on both India and China. Opium was also imported into Britain and was not prohibited because it was thought to be medically beneficial. Laudanum, made from opium, was used as a pain killer, to induce sleep and to suppress anxiety. The famous literary opium addicts Thomas De Quincey, Samuel Taylor Coleridge and Wilkie Collins also took it for its pleasurable effects. The Limehouse area in London was notorious for its opium dens, many of which catered for Chinese sailors as well as English addicts. Clippers were built for seasonal trades such as tea, where an early cargo was more valuable, or for passenger routes. One passenger ship survives, the City of Adelaide designed by William Pile of Sunderland. The fast ships were ideally suited to low-volume, high-profit goods, such as tea, opium, spices, people, and mail. The return could be spectacular. The Challenger returned from Shanghai with "the most valuable cargo of tea and silk ever to be laden in one bottom". Competition among the clippers was public and fierce, with their times recorded in the newspapers. The last China clippers had peak average speeds of over . The Great Tea Race of 1866 showcased their speed. Donald McKay's Sovereign of the Seas reported the highest speed ever achieved by a sailing ship – , made while running her easting down to Australia in 1854. (John Griffiths' first clipper, the Rainbow, had a top speed of 14 knots.) There are eleven other instances of a ship's logging or over. Ten of these were recorded by American clippers. Besides the breath-taking day's run of the Champion of the Seas, there are thirteen other cases of a ship's sailing over in 24 hours. And with few exceptions all the port-to-port sailing records are held by the American clippers. The 24h record of the Champion of the Seas set in 1854, wasn't broken until 1984 (by a multihull), or 2001 (by another monohull). Decline The American clippers sailing from the East Coast to the California goldfields were working in a booming market. Freight rates were high everywhere in the first years of the 1850s. This started to fade in late 1853. The ports of California and Australia reported that they were overstocked with goods that had been shipped earlier in the year. This gave an accelerating fall in freight rates that was halted, however, by the start of the Crimean War in March 1854, as many ships were now being chartered by the French and British governments. The end of the Crimean War in April 1856 released all this capacity back on the world shipping markets - the result being a severe slump. The next year saw the Panic of 1857, which had effects on both sides of the Atlantic. The United States was just starting to recover from this in 1861 when the American Civil War started, causing significant disruption to trade in both Union and Confederate states. As the economic situation deteriorated in 1853, American shipowners either did not order new vessels, or specified an ordinary clipper or a medium clipper instead of an extreme clipper. No extreme clipper was launched in an American shipyard after the end of 1854 and only
of fineness or the prismatic coefficient of various clippers, but measured drawings or accurate half-models may not exist to calculate either of these figures. An alternative measure of sharpness for hulls of a broadly similar shape is the coefficient of under-deck-tonnage, as used by David MacGregor in comparing tea clippers. This could be calculated from the measurements taken to determine the registered tonnage, and so can be applied to more vessels. An "extreme clipper" has a hull of great fineness, as judged either by the prismatic coefficient, the coefficient of under-deck-tonnage or some other technical assessment of hull shape. It is a term that has been misapplied in the past, without reference to hull shape. As commercial vessels, these are totally reliant on speed to generate a profit for their owners, as their sharpness limits their cargo carrying capacity. A "medium clipper" has a cargo-carrying hull that has some sharpness. In the right conditions and with a capable captain, some of these achieved notable quick passages. They were also able to pay their way when the high freight rates often paid to a fast sailer were not available (in a fluctuating market). The term "clipper" applied to vessels between these two categories. They often made passages as fast as extreme clippers, but had less difficulty in making a living when freight rates were lower. History The first ships to which the term "clipper" seems to have been applied were the Baltimore clippers, developed in Chesapeake Bay before the American Revolution, and reaching their zenith between 1795 and 1815. They were small, rarely exceeding 200 tons OM. Their hulls were sharp ended and displayed a lot of deadrise. They were rigged as schooners, brigs or brigantines. In the War of 1812 some were lightly armed, sailing under Letters of Marque and Reprisal, when the type—exemplified by Chasseur, launched at Fells Point, Baltimore in 1814—became known for her incredible speed; the deep draft enabled the Baltimore clipper to sail close to the wind.

it opened in 1979. He made his name as host of the improvised television comedy show Whose Line Is It Anyway?, which ran for 10 series. Anderson hosted his own chat show, Clive Anderson Talks Back (1989–1996), on Channel 4, which ran for 10 series. Anderson moved to the BBC in 1996. After moving to BBC One, the show's name was changed to Clive Anderson All Talk (1996–1999), and it ran for five series. In one incident in 1997, Anderson interviewed the Bee Gees. Throughout the interview, he repeatedly joked about their songs from the Saturday Night Fever era, also referring to their original intended name as 'Les Tosseurs' but his comment, 'you'll always be Les tossers to me' ultimately prompted the band to walk out of the interview. Anderson once had a glass of water poured over his head by a perturbed Richard Branson, to which Anderson remarked "I'm used to that; I've flown Virgin". Alluding to the singer and actress Cher's alleged cosmetic surgery when she was a guest on the show, he asked her "You look like a million dollars - is that how much it cost?" He also said to Jeffrey Archer in response to his derogatory comment about the show, "you're a critic too... there's no beginning to your talents" Archer retorted that "The old ones are always the best," for Anderson to reply "Yes, I've read your books." The last series of Clive Anderson All Talk aired in 2001. He has made ten appearances on Have I Got News for You. He has also frequently appeared on QI. In 2007, he featured as a regular panellist on the ITV comedy show News Knight. One heated exchange on Have I Got News for You occurred when he joked to fellow guest Piers Morgan that the Daily Mirror was now, thanks to Morgan (then its editor), almost as good as The Sun. When asked by Morgan, "What do you know about editing newspapers?" he swiftly replied, "About as much as you do." In 2005, he presented the short-lived quiz Back in the Day for Channel 4. On 25 February 2008, he started to present Brainbox Challenge, a new game show, for BBC Two. Later that year, he presented a talent show-themed reality TV series produced by the BBC entitled Maestro, starring eight celebrities.

He also hosted six series of Clive Anderson's Chat Room on BBC Radio 2 from 2004 to 2009. Anderson has appeared on BBC Radio 4's The Unbelievable Truth hosted by David Mitchell. Anderson also presented the radio show The Guessing Game on BBC Radio Scotland. Anderson has also appeared on BBC Radio 5 Live's Fighting Talk. Comedy and newspaper writing Anderson is a comedy sketch writer who has written for Frankie Howerd, Not the Nine O'Clock News, and Griff Rhys Jones and Mel Smith. One of his early comedy writing projects was Black Cinderella Two Goes East with Rory McGrath for BBC Radio 4 in 1978. As well as writing comedy, Anderson is also a frequent contributor to newspapers and was a regular columnist for The Sunday Correspondent. Personal life Anderson lives in Highbury, North London, with his wife, Jane Anderson, a physician who has spent her career in managing HIV/Aids. He supports Arsenal, Rangers and Albion Rovers football teams. He is President of the Woodland Trust and Vice Patron of the Solicitors' Benevolent Association.

the Bhabha Atomic Research Centre and the Indira Gandhi Centre for Atomic Research. However, there is still skepticism among scientists and, for all practical purposes, research has stalled since the 1990s. A special section in the Indian multidisciplinary journal Current Science published 33 cold fusion papers in 2015 by major cold fusion researchers including several Indian researchers. Reported results A cold fusion experiment usually includes: a metal, such as palladium or nickel, in bulk, thin films or powder; and deuterium, hydrogen, or both, in the form of water, gas or plasma. Electrolysis cells can be either open cell or closed cell. In open cell systems, the electrolysis products, which are gaseous, are allowed to leave the cell. In closed cell experiments, the products are captured, for example by catalytically recombining the products in a separate part of the experimental system. These experiments generally strive for a steady state condition, with the electrolyte being replaced periodically. There are also "heat-after-death" experiments, where the evolution of heat is monitored after the electric current is turned off. The most basic setup of a cold fusion cell consists of two electrodes submerged in a solution containing palladium and heavy water. The electrodes are then connected to a power source to transmit electricity from one electrode to the other through the solution. Even when anomalous heat is reported, it can take weeks for it to begin to appear—this is known as the "loading time," the time required to saturate the palladium electrode with hydrogen (see "Loading ratio" section). The Fleischmann and Pons early findings regarding helium, neutron radiation and tritium were never replicated satisfactorily, and its levels were too low for the claimed heat production and inconsistent with each other. Neutron radiation has been reported in cold fusion experiments at very low levels using different kinds of detectors, but levels were too low, close to background, and found too infrequently to provide useful information about possible nuclear processes. Excess heat and energy production An excess heat observation is based on an energy balance. Various sources of energy input and output are continuously measured. Under normal conditions, the energy input can be matched to the energy output to within experimental error. In experiments such as those run by Fleischmann and Pons, an electrolysis cell operating steadily at one temperature transitions to operating at a higher temperature with no increase in applied current. If the higher temperatures were real, and not an experimental artifact, the energy balance would show an unaccounted term. In the Fleischmann and Pons experiments, the rate of inferred excess heat generation was in the range of 10–20% of total input, though this could not be reliably replicated by most researchers. Researcher Nathan Lewis discovered that the excess heat in Fleischmann and Pons's original paper was not measured, but estimated from measurements that didn't have any excess heat. Unable to produce excess heat or neutrons, and with positive experiments being plagued by errors and giving disparate results, most researchers declared that heat production was not a real effect and ceased working on the experiments. In 1993, after their original report, Fleischmann reported "heat-after-death" experiments—where excess heat was measured after the electric current supplied to the electrolytic cell was turned off. This type of report has also become part of subsequent cold fusion claims. Helium, heavy elements, and neutrons Known instances of nuclear reactions, aside from producing energy, also produce nucleons and particles on readily observable ballistic trajectories. In support of their claim that nuclear reactions took place in their electrolytic cells, Fleischmann and Pons reported a neutron flux of 4,000 neutrons per second, as well as detection of tritium. The classical branching ratio for previously known fusion reactions that produce tritium would predict, with 1 watt of power, the production of 1012 neutrons per second, levels that would have been fatal to the researchers. In 2009, Mosier-Boss et al. reported what they called the first scientific report of highly energetic neutrons, using CR-39 plastic radiation detectors, but the claims cannot be validated without a quantitative analysis of neutrons. Several medium and heavy elements like calcium, titanium, chromium, manganese, iron, cobalt, copper and zinc have been reported as detected by several researchers, like Tadahiko Mizuno or George Miley. The report presented to the United States Department of Energy (DOE) in 2004 indicated that deuterium-loaded foils could be used to detect fusion reaction products and, although the reviewers found the evidence presented to them as inconclusive, they indicated that those experiments did not use state-of-the-art techniques. In response to doubts about the lack of nuclear products, cold fusion researchers have tried to capture and measure nuclear products correlated with excess heat. Considerable attention has been given to measuring 4He production. However, the reported levels are very near to background, so contamination by trace amounts of helium normally present in the air cannot be ruled out. In the report presented to the DOE in 2004, the reviewers' opinion was divided on the evidence for 4He; with the most negative reviews concluding that although the amounts detected were above background levels, they were very close to them and therefore could be caused by contamination from air. One of the main criticisms of cold fusion was that deuteron-deuteron fusion into helium was expected to result in the production of gamma rays—which were not observed and were not observed in subsequent cold fusion experiments. Cold fusion researchers have since claimed to find X-rays, helium, neutrons and nuclear transmutations. Some researchers also claim to have found them using only light water and nickel cathodes. The 2004 DOE panel expressed concerns about the poor quality of the theoretical framework cold fusion proponents presented to account for the lack of gamma rays. Proposed mechanisms Researchers in the field do not agree on a theory for cold fusion. One proposal considers that hydrogen and its isotopes can be absorbed in certain solids, including palladium hydride, at high densities. This creates a high partial pressure, reducing the average separation of hydrogen isotopes. However, the reduction in separation is not enough by a factor of ten to create the fusion rates claimed in the original experiment. It was also proposed that a higher density of hydrogen inside the palladium and a lower potential barrier could raise the possibility of fusion at lower temperatures than expected from a simple application of Coulomb's law. Electron screening of the positive hydrogen nuclei by the negative electrons in the palladium lattice was suggested to the 2004 DOE commission, but the panel found the theoretical explanations not convincing and inconsistent with current physics theories. Criticism Criticism of cold fusion claims generally take one of two forms: either pointing out the theoretical implausibility that fusion reactions have occurred in electrolysis setups or criticizing the excess heat measurements as being spurious, erroneous, or due to poor methodology or controls. There are a couple of reasons why known fusion reactions are an unlikely explanation for the excess heat and associated cold fusion claims. Repulsion forces Because nuclei are all positively charged, they strongly repel one another. Normally, in the absence of a catalyst such as a muon, very high kinetic energies are required to overcome this charged repulsion. Extrapolating from known fusion rates, the rate for uncatalyzed fusion at room-temperature energy would be 50 orders of magnitude lower than needed to account for the reported excess heat. In muon-catalyzed fusion there are more fusions because the presence of the muon causes deuterium nuclei to be 207 times closer than in ordinary deuterium gas. But deuterium nuclei inside a palladium lattice are further apart than in deuterium gas, and there should be fewer fusion reactions, not more. Paneth and Peters in the 1920s already knew that palladium can absorb up to 900 times its own volume of hydrogen gas, storing it at several thousands of times the atmospheric pressure. This led them to believe that they could increase the nuclear fusion rate by simply loading palladium rods with hydrogen gas. Tandberg then tried the same experiment but used electrolysis to make palladium absorb more deuterium and force the deuterium further together inside the rods, thus anticipating the main elements of Fleischmann and Pons' experiment. They all hoped that pairs of hydrogen nuclei would fuse together to form helium, which at the time was needed in Germany to fill zeppelins, but no evidence of helium or of increased fusion rate was ever found. This was also the belief of geologist Palmer, who convinced Steven Jones that the helium-3 occurring naturally in Earth perhaps came from fusion involving hydrogen isotopes inside catalysts like nickel and palladium. This led their team in 1986 to independently make the same experimental setup as Fleischmann and Pons (a palladium cathode submerged in heavy water, absorbing deuterium via electrolysis). Fleischmann and Pons had much the same belief, but they calculated the pressure to be of 1027 atmospheres, when cold fusion experiments achieve a loading ratio of only one to one, which has only between 10,000 and 20,000 atmospheres. John R. Huizenga says they had misinterpreted the Nernst equation, leading them to believe that there was enough pressure to bring deuterons so close to each other that there would be spontaneous fusions. Lack of expected reaction products Conventional deuteron fusion is a two-step process, in which an unstable high-energy intermediary is formed: D + D → 4He * + 24 MeV Experiments have observed only three decay pathways for this excited-state nucleus, with the branching ratio showing the probability that any given intermediate follows a particular pathway. The products formed via these decay pathways are: 4He* → n + 3He + 3.3 MeV (ratio=50%) 4He* → p + 3H + 4.0 MeV (ratio=50%) 4He* → 4He + γ + 24 MeV (ratio=10−6) Only about one in one million of the intermediaries decay along the third pathway, making its products comparatively rare when compared to the other paths. This result is consistent with the predictions of the Bohr model. If one watt (6.242 × 1012 MeV/s) of nuclear power were produced from ~2.2575 × 1011 deuteron fusion individual reactions each second consistent with known branching ratios, the resulting neutron and tritium (3H) production would be easily measured. Some researchers reported detecting 4He but without the expected neutron or tritium production; such a result would require branching ratios strongly favouring the third pathway, with the actual rates of the first two pathways lower by at least five orders of magnitude than observations from other experiments, directly contradicting both theoretically predicted and observed branching probabilities. Those reports of 4He production did not include detection of gamma rays, which would require the third pathway to have been changed somehow so that gamma rays are no longer emitted. The known rate of the decay process together with the inter-atomic spacing in a metallic crystal makes heat transfer of the 24 MeV excess energy into the host metal lattice prior to the intermediary's decay inexplicable in terms of conventional understandings of momentum and energy transfer, and even then there would be measurable levels of radiation. Also, experiments indicate that the ratios of deuterium fusion remain constant at different energies. In general, pressure and chemical environment cause only small changes to fusion ratios. An early explanation invoked the Oppenheimer–Phillips process at low energies, but its magnitude was too small to explain the altered ratios. Setup of experiments Cold fusion setups utilize an input power source (to ostensibly provide activation energy), a platinum group electrode, a deuterium or hydrogen source, a calorimeter, and, at times, detectors to look for byproducts such as helium or neutrons. Critics have variously taken issue with each of these aspects and have asserted that there has not yet been a consistent reproduction of claimed cold fusion results in either energy output or byproducts. Some cold fusion researchers who claim that they can consistently measure an excess heat effect have argued that the apparent lack of reproducibility might be attributable to a lack of quality control in the electrode metal or the amount of hydrogen or deuterium loaded in the system. Critics have further taken issue with what they describe as mistakes or errors of interpretation that cold fusion researchers have made in calorimetry analyses and energy budgets. Reproducibility In 1989, after Fleischmann and Pons had made their claims, many research groups tried to reproduce the Fleischmann-Pons experiment, without success. A few other research groups, however, reported successful reproductions of cold fusion during this time. In July 1989, an Indian group from the Bhabha Atomic Research Centre (P. K. Iyengar and M. Srinivasan) and in October 1989, John Bockris' group from Texas A&M University reported on the creation of tritium. In December 1990, professor Richard Oriani of the University of Minnesota reported excess heat. Groups that did report successes found that some of their cells were producing the effect, while other cells that were built exactly the same and used the same materials were not producing the effect. Researchers that continued to work on the topic have claimed that over the years many successful replications have been made, but still have problems getting reliable replications. Reproducibility is one of the main principles of the scientific method, and its lack led most physicists to believe that the few positive reports could be attributed to experimental error. The DOE 2004 report said among its conclusions and recommendations: Loading ratio Cold fusion researchers (McKubre since 1994, ENEA in 2011) have speculated that a cell that is loaded with a deuterium/palladium ratio lower than 100% (or 1:1) will not produce excess heat. Since most of the negative replications from 1989 to 1990 did not report their ratios, this has been proposed as an explanation for failed reproducibility. This loading ratio is hard to obtain, and some batches of palladium never reach it because the pressure causes cracks in the palladium, allowing the deuterium to escape. Fleischmann and Pons never disclosed the deuterium/palladium ratio achieved in their cells, there are no longer any batches of the palladium used by Fleischmann and Pons (because the supplier now uses a different manufacturing process), and researchers still have problems finding batches of palladium that achieve heat production reliably. Misinterpretation of data Some research groups initially reported that they had replicated the Fleischmann and Pons results but later retracted their reports and offered an alternative explanation for their original positive results. A group at Georgia Tech found problems with their neutron detector, and Texas A&M discovered bad wiring in their thermometers. These retractions, combined with negative results from some famous laboratories, led most scientists to conclude, as early as 1989, that no positive result should be attributed to cold fusion. Calorimetry errors The calculation of excess heat in electrochemical cells involves certain assumptions. Errors in these assumptions have been offered as non-nuclear explanations for excess heat. One assumption made by Fleischmann and Pons is that the efficiency of electrolysis is nearly 100%, meaning nearly all the electricity applied to the cell resulted in electrolysis of water, with negligible resistive heating and substantially all the electrolysis product leaving the cell unchanged. This assumption gives the amount of energy expended converting liquid D2O into gaseous D2 and O2. The efficiency of electrolysis is less than one if hydrogen and oxygen recombine to a significant extent within the calorimeter. Several researchers have described potential mechanisms by which this process could occur and thereby account for excess heat in electrolysis experiments. Another assumption is that heat loss from the calorimeter maintains the same relationship with measured temperature as found when calibrating the calorimeter. This assumption ceases to be accurate if the temperature distribution within the cell becomes significantly altered from the condition under which calibration measurements were made. This can happen, for example, if fluid circulation within the cell becomes significantly altered. Recombination of hydrogen and oxygen within the calorimeter would also alter the heat distribution and invalidate the calibration. Publications The ISI identified cold fusion as the scientific topic with the largest number of published papers in 1989, of all scientific disciplines. The Nobel Laureate Julian Schwinger declared himself a supporter of cold fusion in the fall of 1989, after much of the response to the initial reports had turned negative. He tried to publish his theoretical paper "Cold Fusion: A Hypothesis" in Physical Review Letters, but the peer reviewers rejected it so harshly that he felt deeply insulted, and he resigned from the American Physical Society (publisher of PRL) in protest. The number of papers sharply declined after 1990 because of two simultaneous phenomena: first, scientists abandoned the field; second, journal editors declined to review new papers. Consequently, cold fusion fell off the ISI charts. Researchers who got negative results turned their backs on the field; those who continued to publish were simply ignored. A 1993 paper in Physics Letters A was the last paper published by Fleischmann, and "one of the last reports [by Fleischmann] to be formally challenged on technical grounds by a cold fusion skeptic." The Journal of Fusion Technology (FT) established a permanent feature in 1990 for cold fusion papers, publishing over a dozen
chemical differences between heavy and light water in the presence of lithium. He had not tried to measure any radiation and his research was derided by scientists who saw it later. For the next six weeks, competing claims, counterclaims, and suggested explanations kept what was referred to as "cold fusion" or "fusion confusion" in the news. In April 1989, Fleischmann and Pons published a "preliminary note" in the Journal of Electroanalytical Chemistry. This paper notably showed a gamma peak without its corresponding Compton edge, which indicated they had made a mistake in claiming evidence of fusion byproducts. Fleischmann and Pons replied to this critique, but the only thing left clear was that no gamma ray had been registered and that Fleischmann refused to recognize any mistakes in the data. A much longer paper published a year later went into details of calorimetry but did not include any nuclear measurements. Nevertheless, Fleischmann and Pons and a number of other researchers who found positive results remained convinced of their findings. The University of Utah asked Congress to provide $25 million to pursue the research, and Pons was scheduled to meet with representatives of President Bush in early May. On 30 April 1989 cold fusion was declared dead by The New York Times. The Times called it a circus the same day, and the Boston Herald attacked cold fusion the following day. On 1 May 1989 the American Physical Society held a session on cold fusion in Baltimore, including many reports of experiments that failed to produce evidence of cold fusion. At the end of the session, eight of the nine leading speakers stated that they considered the initial Fleischmann and Pons claim dead, with the ninth, Johann Rafelski, abstaining. Steven E. Koonin of Caltech called the Utah report a result of "the incompetence and delusion of Pons and Fleischmann," which was met with a standing ovation. Douglas R. O. Morrison, a physicist representing CERN, was the first to call the episode an example of pathological science. On 4 May, due to all this new criticism, the meetings with various representatives from Washington were cancelled. From 8 May only the A&M tritium results kept cold fusion afloat. In July and November 1989, Nature published papers critical of cold fusion claims. Negative results were also published in several other scientific journals including Science, Physical Review Letters, and Physical Review C (nuclear physics). In August 1989, in spite of this trend, the state of Utah invested $4.5 million to create the National Cold Fusion Institute. The United States Department of Energy organized a special panel to review cold fusion theory and research. The panel issued its report in November 1989, concluding that results as of that date did not present convincing evidence that useful sources of energy would result from the phenomena attributed to cold fusion. The panel noted the large number of failures to replicate excess heat and the greater inconsistency of reports of nuclear reaction byproducts expected by established conjecture. Nuclear fusion of the type postulated would be inconsistent with current understanding and, if verified, would require established conjecture, perhaps even theory itself, to be extended in an unexpected way. The panel was against special funding for cold fusion research, but supported modest funding of "focused experiments within the general funding system". Cold fusion supporters continued to argue that the evidence for excess heat was strong, and in September 1990 the National Cold Fusion Institute listed 92 groups of researchers from 10 different countries that had reported corroborating evidence of excess heat, but they refused to provide any evidence of their own arguing that it could endanger their patents. However, no further DOE nor NSF funding resulted from the panel's recommendation. By this point, however, academic consensus had moved decidedly toward labeling cold fusion as a kind of "pathological science". In March 1990 Michael H. Salamon, a physicist from the University of Utah, and nine co-authors reported negative results. University faculty were then "stunned" when a lawyer representing Pons and Fleischmann demanded the Salamon paper be retracted under threat of a lawsuit. The lawyer later apologized; Fleischmann defended the threat as a legitimate reaction to alleged bias displayed by cold-fusion critics. In early May 1990 one of the two A&M researchers, Kevin Wolf, acknowledged the possibility of spiking, but said that the most likely explanation was tritium contamination in the palladium electrodes or simply contamination due to sloppy work. In June 1990 an article in Science by science writer Gary Taubes destroyed the public credibility of the A&M tritium results when it accused its group leader John Bockris and one of his graduate students of spiking the cells with tritium. In October 1990 Wolf finally said that the results were explained by tritium contamination in the rods. An A&M cold fusion review panel found that the tritium evidence was not convincing and that, while they couldn't rule out spiking, contamination and measurements problems were more likely explanations, and Bockris never got support from his faculty to resume his research. On 30 June 1991 the National Cold Fusion Institute closed after it ran out of funds; it found no excess heat, and its reports of tritium production were met with indifference. On 1 January 1991 Pons left the University of Utah and went to Europe. In 1992, Pons and Fleischmann resumed research with Toyota Motor Corporation's IMRA lab in France. Fleischmann left for England in 1995, and the contract with Pons was not renewed in 1998 after spending $40 million with no tangible results. The IMRA laboratory stopped cold fusion research in 1998 after spending £12 million. Pons has made no public declarations since, and only Fleischmann continued giving talks and publishing papers. Mostly in the 1990s, several books were published that were critical of cold fusion research methods and the conduct of cold fusion researchers. Over the years, several books have appeared that defended them. Around 1998, the University of Utah had already dropped its research after spending over $1 million, and in the summer of 1997, Japan cut off research and closed its own lab after spending $20 million. Later research A 1991 review by a cold fusion proponent had calculated "about 600 scientists" were still conducting research. After 1991, cold fusion research only continued in relative obscurity, conducted by groups that had increasing difficulty securing public funding and keeping programs open. These small but committed groups of cold fusion researchers have continued to conduct experiments using Fleischmann and Pons electrolysis setups in spite of the rejection by the mainstream community. The Boston Globe estimated in 2004 that there were only 100 to 200 researchers working in the field, most suffering damage to their reputation and career. Since the main controversy over Pons and Fleischmann had ended, cold fusion research has been funded by private and small governmental scientific investment funds in the United States, Italy, Japan, and India. For example, it was reported in Nature, in May, 2019, that Google had spent approximately $10 million on cold fusion research. A group of scientists at well-known research labs (e.g, MIT, Lawrence Berkeley National Lab, and others) worked for several years to establish experimental protocols and measurement techniques in an effort to re-evaluate cold fusion to a high standard of scientific rigor. Their reported conclusion: no cold fusion. In 2021, following Nature's 2019 publication of anomalous findings that might only be explained by some localized fusion, scientists at the Naval Surface Warfare Center, Indian Head Division announced that they had assembled a group of scientists from the Navy, Army and National Institute of Standards and Technology to undertake a new, coordinated study. With few exceptions, researchers have had difficulty publishing in mainstream journals. The remaining researchers often term their field Low Energy Nuclear Reactions (LENR), Chemically Assisted Nuclear Reactions (CANR), Lattice Assisted Nuclear Reactions (LANR), Condensed Matter Nuclear Science (CMNS) or Lattice Enabled Nuclear Reactions; one of the reasons being to avoid the negative connotations associated with "cold fusion". The new names avoid making bold implications, like implying that fusion is actually occurring. The researchers who continue acknowledge that the flaws in the original announcement are the main cause of the subject's marginalization, and they complain of a chronic lack of funding and no possibilities of getting their work published in the highest impact journals. University researchers are often unwilling to investigate cold fusion because they would be ridiculed by their colleagues and their professional careers would be at risk. In 1994, David Goodstein, a professor of physics at Caltech, advocated for increased attention from mainstream researchers and described cold fusion as: United States United States Navy researchers at the Space and Naval Warfare Systems Center (SPAWAR) in San Diego have been studying cold fusion since 1989. In 2002 they released a two-volume report, "Thermal and nuclear aspects of the Pd/D2O system," with a plea for funding. This and other published papers prompted a 2004 Department of Energy (DOE) review. 2004 DOE panel In August 2003, the U.S. Secretary of Energy, Spencer Abraham, ordered the DOE to organize a second review of the field. This was thanks to an April 2003 letter sent by MIT's Peter L. Hagelstein, and the publication of many new papers, including the Italian ENEA and other researchers in the 2003 International Cold Fusion Conference, and a two-volume book by U.S. SPAWAR in 2002. Cold fusion researchers were asked to present a review document of all the evidence since the 1989 review. The report was released in 2004. The reviewers were "split approximately evenly" on whether the experiments had produced energy in the form of heat, but "most reviewers, even those who accepted the evidence for excess power production, 'stated that the effects are not repeatable, the magnitude of the effect has not increased in over a decade of work, and that many of the reported experiments were not well documented.'" In summary, reviewers found that cold fusion evidence was still not convincing 15 years later, and they didn't recommend a federal research program. They only recommended that agencies consider funding individual well-thought studies in specific areas where research "could be helpful in resolving some of the controversies in the field". They summarized its conclusions thus: Cold fusion researchers placed a "rosier spin" on the report, noting that they were finally being treated like normal scientists, and that the report had increased interest in the field and caused "a huge upswing in interest in funding cold fusion research." However, in a 2009 BBC article on an American Chemical Society's meeting on cold fusion, particle physicist Frank Close was quoted stating that the problems that plagued the original cold fusion announcement were still happening: results from studies are still not being independently verified and inexplicable phenomena encountered are being labelled as "cold fusion" even if they are not, in order to attract the attention of journalists. In February 2012, millionaire Sidney Kimmel, convinced that cold fusion was worth investing in by a 19 April 2009 interview with physicist Robert Duncan on the US news show 60 Minutes, made a grant of $5.5 million to the University of Missouri to establish the Sidney Kimmel Institute for Nuclear Renaissance (SKINR). The grant was intended to support research into the interactions of hydrogen with palladium, nickel or platinum under extreme conditions. In March 2013 Graham K. Hubler, a nuclear physicist who worked for the Naval Research Laboratory for 40 years, was named director. One of the SKINR projects is to replicate a 1991 experiment in which a professor associated with the project, Mark Prelas, says bursts of millions of neutrons a second were recorded, which was stopped because "his research account had been frozen". He claims that the new experiment has already seen "neutron emissions at similar levels to the 1991 observation". In May 2016, the United States House Committee on Armed Services, in its report on the 2017 National Defense Authorization Act, directed the Secretary of Defense to "provide a briefing on the military utility of recent U.S. industrial base LENR advancements to the House Committee on Armed Services by September 22, 2016." Italy Since the Fleischmann and Pons announcement, the Italian national agency for new technologies, energy and sustainable economic development (ENEA) has funded Franco Scaramuzzi's research into whether excess heat can be measured from metals loaded with deuterium gas. Such research is distributed across ENEA departments, CNR laboratories, INFN, universities and industrial laboratories in Italy, where the group continues to try to achieve reliable reproducibility (i.e. getting the phenomenon to happen in every cell, and inside a certain frame of time). In 2006–2007, the ENEA started a research program which claimed to have found excess power of up to 500 percent, and in 2009, ENEA hosted the 15th cold fusion conference. Japan Between 1992 and 1997, Japan's Ministry of International Trade and Industry sponsored a "New Hydrogen Energy (NHE)" program of US$20 million to research cold fusion. Announcing the end of the program in 1997, the director and one-time proponent of cold fusion research Hideo Ikegami stated "We couldn't achieve what was first claimed in terms of cold fusion. (...) We can't find any reason to propose more money for the coming year or for the future." In 1999 the Japan C-F Research Society was established to promote the independent research into cold fusion that continued in Japan. The society holds annual meetings. Perhaps the most famous Japanese cold fusion researcher is Yoshiaki Arata, from Osaka University, who
an ointment base such as petrolatum. Construction Coal tar was a component of the first sealed roads. In its original development by Edgar Purnell Hooley, tarmac was tar covered with granite chips. Later the filler used was industrial slag. Today, petroleum derived binders and sealers are more commonly used. These sealers are used to extend the life and reduce maintenance cost associated with asphalt pavements, primarily in asphalt road paving, car parks and walkways. Coal tar is incorporated into some parking-lot sealcoat products used to protect the structural integrity of the underlying pavement. Sealcoat products that are coal-tar based typically contain 20 to 35 percent coal-tar pitch. Research shows it is used throughout the United States of America, however several areas have banned its use in sealcoat products, including the District of Columbia; the city of Austin, Texas; Dane County, Wisconsin; the state of Washington; and several municipalities in Minnesota and others. Industry Being flammable, coal tar is sometimes used for heating or to fire boilers. Like most heavy oils, it must be heated before it will flow easily. A large part of the binder used in the graphite industry for making "green blocks" is coke oven volatiles (COV), a considerable portion of which is coal tar. During the baking process of the green blocks as a part of commercial graphite production, most of the coal tar binders are vaporised and are generally burned in an incinerator to prevent release into the atmosphere, as COV and coal tar can be injurious to health. Coal tar is also used to manufacture paints, synthetic dyes (notably tartrazine/Yellow #5), and photographic materials. In the coal gas era, there were many companies in Britain whose business was to distill coal tar to separate the higher-value fractions, such as naphtha, creosote and pitch. Many industrial chemicals were first isolated from coal tar during this time. These companies included: Bonnington Chemical Works British Tar Products Lancashire Tar Distillers Midland Tar Distillers Newton, Chambers & Company (owners of Izal brand disinfectant) Sadlers Chemicals Safety Side effects of coal tar products include skin irritation, sun sensitivity, allergic reactions, and skin discoloration. It is unclear if use during pregnancy is safe for the baby and use during breastfeeding is not typically recommended. According to the National Psoriasis Foundation, coal tar is a valuable, safe and inexpensive treatment option for millions of people with psoriasis and other scalp or skin conditions. According to the FDA, coal tar concentrations between 0.5% and 5% are considered safe and effective for psoriasis. Cancer Long-term, consistent exposure to coal tar likely increases the risk of non-melanoma skin cancers. Evidence is inconclusive whether medical coal tar, which does not remain on the skin for the long periods seen in occupational exposure, causes cancer, because there is insufficient data to make a judgment. While coal tar consistently causes cancer in cohorts of workers with chronic occupational exposure, animal models, and mechanistic studies, the data on short-term use as medicine in humans has so far failed to show any consistently significant increase in rates of cancer. Coal tar contains many polycyclic aromatic hydrocarbons, and it is believed that their metabolites bind to DNA, damaging it. The PAHs found in coal tar and air pollution induce immunosenescence and cytotoxicity in epidermal cells. It's possible that the skin can repair itself from this damage after short-term exposure to PAHs but

The PAHs found in coal tar and air pollution induce immunosenescence and cytotoxicity in epidermal cells. It's possible that the skin can repair itself from this damage after short-term exposure to PAHs but not after long-term exposure. Long-term skin exposure to these compounds can produce "tar warts", which can progress to squamous cell carcinoma. Coal tar was one of the first chemical substances proven to cause cancer from occupational exposure, during research in 1775 on the cause of chimney sweeps' carcinoma. Modern studies have shown that working with coal tar pitch, such as during the paving of roads or when working on roofs, increases the risk of cancer. The International Agency for Research on Cancer lists coal tars as Group 1 carcinogens, meaning they directly cause cancer. Both the U.S. Department of Health and Human Services and the state of California list coal tars as known human carcinogens. In response to public health concerns regarding the carcinogenicity of PAHs some municipalities, such as the city of Milwaukee, have banned the use of common coal tar-based road and driveway sealants citing concerns of elevated PAH content in groundwater.

city and Lucca away from alliance with the anti-papal league whose force was gaining momentum and strength. She also lent her enthusiasm towards promoting the launch of a new crusade. It was in Pisa in 1375 that, according to Raymond of Capua's biography, she received the stigmata (visible, at Catherine's request, only to herself). Physical travel was not the only way in which Catherine made her views known. From 1375 onwards, she began dictating letters to scribes. These letters were intended to reach men and women of her circle, increasingly widening her audience to include figures in authority as she begged for peace between the republics and principalities of Italy and for the return of the Papacy from Avignon to Rome. She carried on a long correspondence with Pope Gregory XI, asking him to reform the clergy and the administration of the Papal States. Towards the end of 1375, she returned to Siena, to assist a young political prisoner, Niccolò di Tuldo, at his execution. In June 1376 Catherine went to Avignon as ambassador of the Republic of Florence to make peace with the Papal States (on 31 March 1376 Gregory XI had placed Florence under interdict). She was unsuccessful and was disowned by the Florentine leaders, who sent ambassadors to negotiate on their own terms as soon as Catherine's work had paved the way for them. Catherine sent an appropriately scorching letter back to Florence in response. While in Avignon, Catherine also tried to convince Pope Gregory XI, the last Avignon Pope, to return to Rome. Gregory did indeed return his administration to Rome in January 1377; to what extent this was due to Catherine's influence is a topic of much modern debate. Catherine returned to Siena and spent the early months of 1377 founding a women's monastery of strict observance outside the city in the old fortress of Belcaro. She spent the rest of 1377 at Rocca d'Orcia, about twenty miles from Siena, on a local mission of peace-making and preaching. During this period, in autumn 1377, she had the experience which led to the writing of her Dialogue and learned to write, although she still seems to have chiefly relied upon her secretaries for her correspondence. Late in 1377 or early in 1378 Catherine again travelled to Florence, at the order of Gregory XI, to seek peace between Florence and Rome. Following Gregory's death in March 1378 riots, the revolts of the Ciompi, broke out in Florence on 18 June, and in the ensuing violence she was nearly assassinated. Eventually, in July 1378, peace was agreed between Florence and Rome; Catherine returned quietly to Florence. In late November 1378, with the outbreak of the Western Schism, the new Pope, Urban VI, summoned her to Rome. She stayed at Pope Urban VI's court and tried to convince nobles and cardinals of his legitimacy, both meeting with individuals at court and writing letters to persuade others. For many years she had accustomed herself to a rigorous abstinence. She received the Holy Eucharist almost daily. This extreme fasting appeared unhealthy in the eyes of the clergy and her own sisterhood. Her confessor, Raymond, ordered her to eat properly. But Catherine claimed that she was unable to, describing her inability to eat as an infermità (illness). From the beginning of 1380, Catherine could neither eat nor swallow water. On 26 February she lost the use of her legs. Catherine died in Rome, on 29 April 1380, at the age of thirty-three, having eight days earlier suffered a massive stroke which paralyzed her from the waist down. Her last words were, "Father, into Your Hands I commend my soul and my spirit." Sources of her life There is some internal evidence of Catherine's personality, teaching and work in her nearly four hundred letters, her Dialogue, and her prayers. Much detail about her life has also, however, been drawn from the various sources written shortly after her death in order to promote her cult and canonization. Though much of this material is heavily hagiographic, it has been an important source for historians seeking to reconstruct Catherine's life. Various sources are particularly important, especially the works of Raymond of Capua, who was Catherine's spiritual director and close friend from 1374 until her death, and himself became Master General of the Order in 1380. Raymond wrote what is known as the Legenda Major, his Life of Catherine which was completed in 1395, fifteen years after Catherine's death. Another important work written after Catherine's death was Libellus de Supplemento (Little Supplement Book), written between 1412 and 1418 by Tommaso d'Antonio Nacci da Siena (commonly called Thomas of Siena, or Tommaso Caffarini); the work is an expansion of Raymond's Legenda Major making heavy use of the notes of Catherine's first confessor, Tommaso della Fonte (notes that do not survive anywhere else). Caffarini later published a more compact account of Catherine's life, entitled the Legenda Minor. From 1411 onwards, Caffarini also coordinated the compiling of the Processus of Venice, the set of documents submitted as part of the process of canonisation of Catherine, which provides testimony from nearly all of Catherine's disciples. There is also an anonymous piece entitled "Miracoli della Beata Caterina" (Miracle of Blessed Catherine), written by an anonymous Florentine. A few other relevant pieces survive. Works Three genres of work by Catherine survive: Her major treatise is The Dialogue of Divine Providence. This had probably begun in October 1377 and was certainly finished by November 1378. Contemporaries of Catherine are united in asserting that much of the book was dictated while Catherine was in ecstasy, though it also seems possible that Catherine herself may then have re-edited many passages in the book. It is a dialogue between a soul who "rises up" to God and God himself. Catherine's letters are considered one of the great works of early Tuscan literature. Many of these were dictated, although she herself learned to write in 1377; 382 have survived. In her letters to the Pope, she often addressed him affectionately simply as Babbo ("Daddy"), instead of the formal form of address "Your Holiness". Other correspondents include her various confessors, among them Raymond of Capua, the kings of France and Hungary, the infamous mercenary John Hawkwood, the Queen of Naples, members of the Visconti family of Milan, and numerous religious figures. Approximately one third of her letters are to women. Twenty-six prayers of Catherine of Siena also survive, mostly composed in the last eighteen months of her life. The University of Alcalá conserves a unique handwritten Spanish manuscript, while other available texts are printed copies collected by the National Library of France. Theology Catherine's theology can be described as mystical, and was employed towards practical ends for her own spiritual life or those of others. She used the language of medieval scholastic philosophy to elaborate her experiential mysticism. Interested mainly with achieving an incorporeal union with God, Catherine practiced extreme fasting and asceticism, eventually to the extent of living solely off the Eucharist every day. For Catherine, this practice was the means to fully realize her love of Christ in her mystical experience, with a large proportion of her ecstatic visions relating to the consumption or rejection of food during her life. She viewed Christ as a "bridge" between the soul and God and transmitted that idea, along with her other teachings, in her book The Dialogue. The Dialogue is highly systematic and explanatory in its presentation of her mystical ideas; however, these ideas themselves are not so much based on reason or logic as they are based in her ecstatic mystical experience. In one of her letters she sent to her confessor, Raymund of Capua, she recorded this revelation from her conversation with Christ, in which he said: "Do you know what you are to Me, and what I am to you, my daughter? I am He who is, you are she who is not". This mystical concept of God as the wellspring of being is seen in the works and ideas of Aquinas and can be seen as a simplistic rendering of apotheosis and a more rudimentary form of the doctrine of divine simplicity. She describes God in her work, 'the Dialogues, as a "sea, in which we are the fish", the point being that the relationship between God and man should not be seen as man contending against the Divine and vice versa, but as God being the endless being that supports all things. Veneration She was buried in the (Roman) cemetery of Santa Maria sopra Minerva which lies near the Pantheon. After miracles were reported to take place at her grave, Raymond moved her

Veneration She was buried in the (Roman) cemetery of Santa Maria sopra Minerva which lies near the Pantheon. After miracles were reported to take place at her grave, Raymond moved her inside the Basilica of Santa Maria sopra Minerva, where she lies to this day. Her head however, was parted from her body and inserted in a gilt bust of bronze. This bust was later taken to Siena, and carried through that city in a procession to the Dominican church. Behind the bust walked Lapa, Catherine's mother, who lived until she was 89 years old. By then she had seen the end of the wealth and the happiness of her family, and followed most of her children and several of her grandchildren to the grave. She helped Raymond of Capua write his biography of her daughter, and said, "I think God has laid my soul athwart in my body, so that it can't get out." The incorrupt head and thumb were entombed in the Basilica of San Domenico at Siena, where they remain. Pope Pius II, himself from Siena, canonized Catherine on 29 June 1461. On 4 October 1970, Pope Paul VI named Catherine a Doctor of the Church; this title was almost simultaneously given to Teresa of Ávila (27 September 1970), making them the first women to receive this honour. Initially however, her feast day was not included in the General Roman Calendar. When it was added in 1597, it was put on the day of her death, 29 April; however, because this conflicted with the feast of Saint Peter of Verona which also fell on 29 April, Catherine's feast day was moved in 1628 to the new date of 30 April. In the 1969 revision of the calendar, it was decided to leave the celebration of the feast of St Peter of Verona to local calendars, because he was not as well known worldwide, and Catherine's feast was restored to 29 April. Catherine is remembered in the Church of England with a Lesser Festival on 29 April. Patronage In his decree of 13 April 1866, Pope Pius IX declared Catherine of Siena to be a co-patroness of Rome. On 18 June 1939 Pope Pius XII named her a joint patron saint of Italy along with Saint Francis of Assisi. On 1 October 1999, Pope John Paul II made her one of Europe's patron saints, along with Saint Teresa Benedicta of the Cross and Saint Bridget of Sweden. She is also the patroness of the historically Catholic American woman's fraternity, Theta Phi Alpha. Severed head The people of Siena wished to have Catherine's body. A story is told of a miracle whereby they were partially successful: knowing that they could not smuggle her whole body out of Rome, they decided to take only her head which they placed in a bag. When stopped by the Roman guards, they prayed to Catherine to help them, confident that she would rather have her body (or at least part thereof) in Siena. When they opened the bag to show the guards, it appeared no longer to hold her head but to be full of rose petals. Legacy Catherine ranks high among the mystics and spiritual writers of the Church. She remains a greatly respected figure for her spiritual writings, and political boldness to "speak truth to power"—it being exceptional for a woman, in her time period, to have had such influence in politics and on world history. Main sanctuaries The main churches in honor of Catherine of Siena are: Santa Maria sopra Minerva in Rome: place where her body is preserved. Basilica of San Domenico in Siena: in this church the incorrupt head of Catherine of Siena is preserved. in Siena: complex of religious buildings built around the birthplace of Catherine. Images Works Modern editions and English translations''' The Italian critical edition of the Dialogue is Catherine of Siena, Il Dialogo della divina Provvidenza: ovvero Libro della divina dottrina, 2nd ed., ed. Giuliana Cavallini (Siena: Cantagalli, 1995). [1st edn, 1968] [Cavallini demonstrated that the standard division of the Dialogue in into four treatises entitled the 'Treatise on Discretion', 'On Prayer', 'On Providence', and 'On Obedience', was in fact a result of a misreading of the text in the 1579 edition of the Dialogue. Modern editors and translators, including Noffke (1980), have followed Cavallini in rejecting this fourfold division.] The Italian critical
intended the book to act as a suitable field guide for students of geology. The systematic, factual description of geological formations of different ages contained in Principles grew so unwieldy, however, that Lyell split it off as the Elements in 1838. The book went through six editions, eventually growing to two volumes and ceasing to be the inexpensive, portable handbook that Lyell had originally envisioned. Late in his career, therefore, Lyell produced a condensed version titled Student's Elements of Geology that fulfilled the original purpose. Geological Evidences of the Antiquity of Man brought together Lyell's views on three key themes from the geology of the Quaternary Period of earth history: glaciers, evolution, and the age of the human race. First published in 1863, it went through three editions that year, with a fourth and final edition appearing in 1873. The book was widely regarded as a disappointment because of Lyell's equivocal treatment of evolution. Lyell, a highly religious man with a strong belief in the special status of human reason, had great difficulty reconciling his beliefs with natural selection. Scientific contributions Lyell's geological interests ranged from volcanoes and geological dynamics through stratigraphy, palaeontology, and glaciology to topics that would now be classified as prehistoric archaeology and paleoanthropology. He is best known, however, for his role in elaborating the doctrine of uniformitarianism. He played a critical role in advancing the study of loess. Uniformitarianism From 1830 to 1833 his multi-volume Principles of Geology was published. The work's subtitle was "An attempt to explain the former changes of the earth's surface by reference to causes now in operation", and this explains Lyell's impact on science. He drew his explanations from field studies conducted directly before he went to work on the founding geology text. He was, along with the earlier John Playfair, the major advocate of James Hutton's idea of uniformitarianism, that the earth was shaped entirely by slow-moving forces still in operation today, acting over a very long period of time. This was in contrast to catastrophism, an idea of abrupt geological changes, which had been adapted in England to explain landscape features—such as rivers much smaller than their associated valleys—that seemed impossible to explain other than through violent action. Criticizing the reliance of his contemporaries on what he argued were ad hoc explanations, Lyell wrote, Never was there a doctrine more calculated to foster indolence, and to blunt the keen edge of curiosity, than this assumption of the discordance between the former and the existing causes of change... The student was taught to despond from the first. Geology, it was affirmed, could never arise to the rank of an exact science... [With catastrophism] we see the ancient spirit of speculation revived, and a desire manifestly shown to cut, rather than patiently untie, the Gordian Knot.-Sir Charles Lyell, Principles of Geology, 1854 edition, p. 196; quoted by Stephen Jay Gould. Lyell saw himself as "the spiritual saviour of geology, freeing the science from the old dispensation of Moses." The two terms, uniformitarianism and catastrophism, were both coined by William Whewell; in 1866 R. Grove suggested the simpler term continuity for Lyell's view, but the old terms persisted. In various revised editions (12 in all, through 1872), Principles of Geology was the most influential geological work in the middle of the 19th century, and did much to put geology on a modern footing. Geological surveys Lyell noted the "economic advantages" that geological surveys could provide, citing their felicity in mineral-rich countries and provinces. Modern surveys, like the British Geological Survey (founded in 1835), and the US Geological Survey (founded in 1879), map and exhibit the natural resources within their countries. Over time, these surveys have been used extensively by modern extractive industries, such as nuclear, coal and oil. Volcanoes and geological dynamics Before the work of Lyell, phenomena such as earthquakes were understood by the destruction that they brought. One of the contributions that Lyell made in Principles was to explain the cause of earthquakes. Lyell, in contrast focused on recent earthquakes (150 yrs), evidenced by surface irregularities such as faults, fissures, stratigraphic displacements and depressions. Lyell's work on volcanoes focused largely on Vesuvius and Etna, both of which he had earlier studied. His conclusions supported gradual building of volcanoes, so-called "backed up-building", as opposed to the upheaval argument supported by other geologists. Stratigraphy and human history Lyell was a key figure in establishing the classification of more recent geological deposits, long known as the Tertiary period. From May 1828, until February 1829, he travelled with Roderick Impey Murchison (1792–1871) to the south of France (Auvergne volcanic district) and to Italy. In these areas he concluded that the recent strata (rock layers) could be categorised according to the number and proportion of marine shells encased within. Based on this the third volume of his Principles of Geology, published in 1833, proposed dividing the Tertiary period into four parts, which he named the Eocene, Miocene, Pliocene, and Recent. In 1839, Lyell termed the Pleistocene epoch, distinguishing a more recent fossil layer from the Pliocene. The Recent epoch renamed the Holocene by French paleontologist Paul Gervais in 1867 included all deposits from the era subject to human observation. In recent years Lyell's subdivisions have been widely discussed in relation to debates about the Anthropocene. Glaciers In Principles of Geology (first edition, vol. 3, ch. 2, 1833) Lyell proposed that icebergs could be the means of transport for erratics. During periods of global warming, ice breaks off the poles and floats across submerged continents, carrying debris with it, he conjectured. When the iceberg melts, it rains down sediments upon the land. Because this theory could account for the presence of diluvium, the word drift became the preferred term for the loose, unsorted material, today called till. Furthermore, Lyell believed that the accumulation of fine angular particles covering much of the world (today called loess) was a deposit settled from mountain flood water. Today some of Lyell's mechanisms for geological processes have been disproven, though many have stood the test of time. His observational methods and general analytical framework remain in use today as foundational principles in geology. Evolution Lyell initially accepted the conventional view of other men of science, that the fossil record indicated a directional geohistory in which species went extinct. Around 1826, when he was on circuit, he read Lamarck's Zoological Philosophy and on 2 March 1827 wrote to Mantell, expressing admiration, but cautioning that he read it "rather as I hear an advocate on the wrong side, to know what can be made of the case in good hands".: I devoured Lamarck... his theories delighted me... I am glad that he has been courageous enough and logical enough to admit that his argument, if pushed as far as it must go, if worth anything, would prove that men may have come from the Ourang-Outang. But after all, what changes species may really undergo!... That the earth is quite as old as he supposes, has long been my creed... He struggled with the implications for human dignity, and later in 1827 wrote private notes on Lamarck's ideas. Lyell reconciled transmutation of species with natural theology by suggesting that it would be as much a "remarkable manifestation of creative Power" as creating each species separately. He countered Lamarck's views by rejecting continued cooling of the earth in favour of "a fluctuating cycle", a long-term steady-state geohistory as proposed by James Hutton. The fragmentary fossil record already showed "a high class of fishes, close to reptiles" in the Carboniferous period which he called "the first Zoological era", and quadrupeds could also have existed then. In November 1827, after William Broderip found a Middle Jurassic fossil of the early mammal Didelphis, Lyell told his father that "There was everything but man even as far back as the Oolite." Lyell inaccurately portrayed Lamarckism as a response to the fossil record, and said it was falsified by a lack of progress. He said in the second volume of Principles that the occurrence of this one fossil of the higher mammalia "in these ancient strata, is as fatal to the theory of successive development, as if several hundreds had been discovered." In the first edition of Principles, the first volume briefly set out Lyell's concept of a steady state with no real progression of fossils. The sole exception was the advent of humanity, with no great physical distinction from animals, but with absolutely unique intellectual and moral qualities. The second volume dismissed Lamarck's claims of animal forms arising from habits, continuous spontaneous generation of new life, and man having evolved from lower forms. Lyell explicitly rejected Lamarck's concept of transmutation of species, drawing on Cuvier's arguments, and concluded that species had been created with stable attributes. He discussed the geographical distribution of plants and animals, and proposed that every species of plant or animal was descended from a pair or individual, originated in response to differing external conditions. Species would regularly go extinct, in a "struggle for existence" between hybrids, or a "war one with another" due to population pressure. He was vague about how replacement species formed, portraying this as an infrequent occurrence which could rarely be observed. The leading man of science Sir John Herschel wrote from Cape Town on 20 February 1836, thanking Lyell for sending a copy of Principles and praising the book as opening a way for bold speculation on "that mystery of mysteries, the replacement of extinct species by others" – by analogy with other intermediate causes, "the origination of fresh species, could it ever come under our cognizance, would be found to be a natural in contradistinction to a miraculous process". Lyell replied: "In regard to the origination of new species, I am very glad to find that you think it probable that it may be carried on through the intervention of intermediate causes. I left this rather to be inferred, not thinking it worth while to offend a certain class of persons by embodying in words what would only be a speculation." Whewell subsequently questioned this topic, and in

Whewell subsequently questioned this topic, and in March 1837 Lyell told him: If I had stated... the possibility of the introduction or origination of fresh species being a natural, in contradistinction to a miraculous process, I should have raised a host of prejudices against me, which are unfortunately opposed at every step to any philosopher who attempts to address the public on these mysterious subjects... As a result of his letters and, no doubt, personal conversations, Huxley and Haeckel were convinced that, at the time he wrote Principles, he believed new species had arisen by natural methods. Sedgwick wrote worried letters to him about this. By the time Darwin returned from the Beagle survey expedition in 1836, he had begun to doubt Lyell's ideas about the permanence of species. He continued to be a close personal friend, and Lyell was one of the first scientists to support On the Origin of Species, though he did not subscribe to all its contents. Lyell was also a friend of Darwin's closest colleagues, Hooker and Huxley, but unlike them he struggled to square his religious beliefs with evolution. This inner struggle has been much commented on. He had particular difficulty in believing in natural selection as the main motive force in evolution. Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and Alfred Russel Wallace in 1858: each had arrived at the theory independently. Lyell's views on gradual change and the power of a long time scale were important because Darwin thought that populations of an organism changed very slowly. Although Lyell rejected evolution at the time of writing the Principles, after the Darwin–Wallace papers and the Origin Lyell wrote in one of his notebooks on 3 May 1860: Mr. Darwin has written a work which will constitute an era in geology & natural history to show that... the descendants of common parents may become in the course of ages so unlike each other as to be entitled to rank as a distinct species, from each other or from some of their progenitors... Lyell's acceptance of natural selection, Darwin's proposed mechanism for evolution, was equivocal, and came in the tenth edition of Principles. The Antiquity of Man (published in early February 1863, just before Huxley's Man's place in nature) drew these comments from Darwin to Huxley: "I am fearfully disappointed at Lyell's excessive caution" and "The book is a mere 'digest'". Quite strong remarks: no doubt Darwin resented Lyell's repeated suggestion that he owed a lot to Lamarck, whom he (Darwin) had always specifically rejected. Darwin's daughter Henrietta (Etty) wrote to her father: "Is it fair that Lyell always calls your theory a modification of Lamarck's?" In other respects Antiquity was a success. It sold well, and it "shattered the tacit agreement that mankind should be the sole preserve of theologians and historians". But when Lyell wrote that it remained a profound mystery how the huge gulf between man and beast could be bridged, Darwin wrote "Oh!" in the margin of his copy.

in 1948. In 1980, Stamford Bridge hosted the first international floodlit cricket match in the UK, between Essex and the West Indies. It was also the home stadium of the London Monarchs American Football team for the 1997 season. The current club ownership have stated that a larger stadium is necessary in order for Chelsea to stay competitive with rival clubs who have significantly larger stadia, such as Arsenal and Manchester United. Owing to its location next to a main road and two railway lines, fans can only enter Stamford Bridge via the Fulham Road exits, which places constraints on expansion due to health and safety regulations. The club have consistently affirmed their desire to keep Chelsea at their current home, but have nonetheless been linked with a move to various nearby sites, including the Earls Court Exhibition Centre, Battersea Power Station and the Chelsea Barracks. In October 2011, a proposal from the club to buy back the freehold to the land on which Stamford Bridge sits was voted down by Chelsea Pitch Owners shareholders. In May 2012, the club made a formal bid to purchase Battersea Power Station, with a view to developing the site into a new stadium, but lost out to a Malaysian consortium. The club subsequently announced plans to redevelop Stamford Bridge into a 60,000-seater stadium, and in January 2017 these plans were approved by Hammersmith and Fulham council. However, on 31 May 2018, the club released a statement saying that the new stadium project had been put on hold indefinitely, citing "the current unfavourable investment climate." Crest and colours Crest Chelsea have had four main crests, which all underwent minor variations. The first, adopted when the club was founded, was the image of a Chelsea pensioner, the army veterans who reside at the nearby Royal Hospital Chelsea. This contributed to the club's original "pensioner" nickname, and remained for the next half-century, though it never appeared on the shirts. When Ted Drake became Chelsea manager in 1952, he began to modernise the club. Believing the Chelsea pensioner crest to be old-fashioned, he insisted that it be replaced. A stop-gap badge which comprised the initials C.F.C. was adopted for a year. In 1953, the club crest was changed to an upright blue lion looking backwards and holding a staff. It was based on elements in the coat of arms of the Metropolitan Borough of Chelsea with the "lion rampant regardant" taken from the arms of then club president Viscount Chelsea and the staff from the Abbots of Westminster, former Lords of the Manor of Chelsea. It also featured three red roses, to represent England, and two footballs. This was the first Chelsea crest to appear on the shirts, in the early 1960s. In 1975, a heraldic badge was granted by the College of Arms to the English Football League for use by Chelsea. The badge took the form of the familiar lion and staff encircled by a blue ring but without lettering and without the red roses and red footballs (blazoned as "A lion rampant reguardant azure supporting with the forepaws a crozier or all within an annulet azure"). In 1986, with Ken Bates now owner of the club, Chelsea's crest was changed again as part of another attempt to modernise and because the old rampant lion badge could not be trademarked. The new badge featured a more naturalistic non-heraldic lion, in white and not blue, standing over the C.F.C. initials. This lasted for the next 19 years, with some modifications such as the use of different colours, including red from 1987 to 1995, and yellow from 1995 until 1999, before the white returned. With the new ownership of Roman Abramovich, and the club's centenary approaching, combined with demands from fans for the popular 1950s badge to be restored, it was decided that the crest should be changed again in 2005. The new crest was officially adopted for the start of the 2005–06 season and marked a return to the older design, used from 1953 to 1986, featuring a blue heraldic lion holding a staff. For the centenary season this was accompanied by the words '100 YEARS' and 'CENTENARY 2005–2006' on the top and bottom of the crest respectively. Colours Chelsea have always worn blue shirts, although they originally used the paler eton blue, which was taken from the racing colours of then club president, Earl Cadogan, and was worn with white shorts and dark blue or black socks. The light blue shirts were replaced by a royal blue version in around 1912. In the 1960s Chelsea manager Tommy Docherty changed the kit again, switching to blue shorts (which have remained ever since) and white socks, believing it made the club's colours more modern and distinctive, since no other major side used that combination; this kit was first worn during the 1964–65 season. Since then Chelsea have always worn white socks with their home kit apart from a short spell from 1985 to 1992, when blue socks were reintroduced. Chelsea's away colours are usually all yellow or all white with blue trim. More recently, the club have had a number of black or dark blue away kits which alternate every year. As with most teams, they have also had some more unusual ones. At Docherty's behest, in the 1966 FA Cup semi-final they wore blue and black stripes, based on Inter Milan's kit. In the mid-1970s, the away strip was a red, white and green kit inspired by the Hungarian national side of the 1950s. Other away kits include an all jade strip worn from 1986 to 1989, red and white diamonds from 1990 to 1992, graphite and tangerine from 1994 to 1996, and luminous yellow from 2007 to 2008. The graphite and tangerine strip has appeared in lists of the worst football kits ever. Support Chelsea are among the most widely supported football clubs in the world. They have the sixth highest average attendance in the history of English football, and regularly attract over 40,000 fans to Stamford Bridge; they were the seventh best-supported Premier League team in the 2013–14 season, with an average gate of 41,572. Chelsea's traditional fanbase comes from all over the Greater London area including working-class parts such as Hammersmith and Battersea, wealthier areas like Chelsea and Kensington, and from the home counties. There are also numerous official supporters clubs in the United Kingdom and all over the world. Between 2007 and 2012, Chelsea were ranked fourth worldwide in annual replica kit sales, with an average of 910,000. As of 2018, Chelsea had 72.2 million followers on social media, the fourth highest among football clubs. At matches, Chelsea fans sing chants such as "Carefree" (to the tune of "Lord of the Dance", whose lyrics were probably written by supporter Mick Greenaway), "Ten Men Went to Mow", "We All Follow the Chelsea" (to the tune of "Land of Hope and Glory"), "Zigga Zagga", and the celebratory "Celery". The latter is often accompanied by fans throwing celery at each other, although the vegetable was banned inside Stamford Bridge after an incident involving Arsenal midfielder Cesc Fàbregas at the 2007 League Cup Final. During the 1970s and 1980s in particular, Chelsea supporters were associated with football hooliganism. The club's "football firm", originally known as the Chelsea Shed Boys, and subsequently as the Chelsea Headhunters, were nationally notorious for football violence, alongside hooligan firms from other clubs such as West Ham United's Inter City Firm and Millwall's Bushwackers, before, during and after matches. The increase of hooligan incidents in the 1980s led chairman Ken Bates to propose erecting an electric fence to deter them from invading the pitch, a proposal that the Greater London Council rejected. Since the 1990s, there has been a marked decline in crowd trouble at matches, as a result of stricter policing, CCTV in grounds and the advent of all-seater stadia. In 2007, the club launched the Back to the Shed campaign to improve the atmosphere at home matches, with notable success. According to Home Office statistics, 126 Chelsea fans were arrested for football-related offences during the 2009–10 season, the third highest in the division, and 27 banning orders were issued, the fifth-highest in the division. Rivalries Chelsea have long-standing rivalries with North London clubs Arsenal and Tottenham Hotspur. A strong rivalry with Leeds United dates back to several heated and controversial matches in the 1960s and 1970s, particularly the 1970 FA Cup Final. More recently a rivalry with Liverpool has grown following repeated clashes in cup competitions. Chelsea's fellow West London sides Brentford, Fulham and Queens Park Rangers are generally not considered major rivals, as matches have only taken place intermittently due to the clubs often being in separate divisions. A 2004 survey by Planetfootball.com found that Chelsea fans consider their main rivalries to be with (in descending order): Arsenal, Tottenham Hotspur and Manchester United. In the same survey, fans of Arsenal, Fulham, Leeds United, QPR, Tottenham, and West Ham United named Chelsea as one of their three main rivals. In a 2008 poll conducted by the Football Fans Census, Chelsea fans named Liverpool, Arsenal and Manchester United as their most disliked clubs. In the same survey, "Chelsea" was the top answer to the question "Which other English club do you dislike the most?" A 2012 survey, conducted among 1,200 supporters of the top four league divisions across the country, found that many clubs' main rivals had changed since 2003 and reported that Chelsea fans consider Tottenham to be their main rivals, above Arsenal and Manchester United. Additionally, fans of Arsenal, Brentford, Fulham, Liverpool, Manchester United, QPR, Tottenham and West Ham identified Chelsea as one of their top three rivals. Records Chelsea's highest appearance-maker is ex-captain Ron Harris, who played in 795 competitive games for the club between 1961 and 1980. Four other players made more than 500 appearances for the club: Peter Bonetti (729; 1959–79), John Terry (717; 1998–2017), Frank Lampard (648; 2001–2014) and John Hollins (592; 1963–1975 and 1983–1984). With 103 caps (101 while at the club) for England, Lampard is Chelsea's most capped international player. Every starting player in Chelsea's 57 games of the 2013–14 season was a full international – a new club record. Lampard is Chelsea's all-time top goalscorer, having scored 211 goals in 648 games (2001–2014); he passed Bobby Tambling's longstanding record of 202 in May 2013. Eight other players have also scored over 100 goals for Chelsea: George Hilsdon (1906–1912), George Mills (1929–1939), Roy Bentley (1948–1956), Jimmy Greaves (1957–1961), Peter Osgood (1964–1974 and 1978–1979), Kerry Dixon (1983–1992), Didier Drogba (2004–2012 and 2014–2015), and Eden Hazard (2012–2019). Greaves holds the club record for the most goals scored in one season (43 in 1960–61). While a Chelsea player, Greaves also became the youngest ever player to score 100 goals in the English top-flight, at 20 years and 290 days. Chelsea's biggest winning scoreline in a competitive match is 13–0, achieved against Jeunesse Hautcharage in the Cup Winners' Cup in 1971. The club's biggest top-flight win was an 8–0 victory against Wigan Athletic in 2010, which was matched in 2012 against Aston Villa. Chelsea's biggest loss was an 8–1 reverse against Wolverhampton Wanderers in 1953. The club's 21–0 aggregate victory over Jeunesse Hautcharage in the UEFA Cup Winners' Cup in 1971 is also a record in European competition. Officially, Chelsea's highest home attendance is 82,905 for a First Division match against Arsenal on 12 October 1935. However, an estimated crowd of over 100,000 attended a friendly match against Soviet team Dynamo Moscow on 13 November 1945. From 20 March 2004 to 26 October 2008, Chelsea went a record 86 consecutive league matches at home without defeat, beating the previous record of 63 matches unbeaten set by Liverpool between 1978 and 1980. Chelsea hold the English record for the fewest goals conceded during a league season (15), the highest number of clean sheets overall in a Premier League season (25) (both set during the 2004–05 season), and the most consecutive clean sheets from the start of a league season (6, set during the 2005–06 season). Chelsea's streak of eleven consecutive away league wins, set between 5 April 2008 and 6 December 2008, is a record for the English top flight. Chelsea are the only Premier League side to win their opening nine league games of the season, doing so in 2005–06. From 2009 to 2013, Chelsea were unbeaten in a record 29 consecutive FA Cup matches (excluding penalty shoot-outs). On 25 August 1928, Chelsea, along with Arsenal, became the first club to play with shirt numbers, in their match against Swansea Town. They were the first English side to travel by aeroplane to a domestic away match, when they visited Newcastle United on 19 April 1957, and the first First Division side to play a match on a Sunday, when they faced Stoke City on 27 January 1974. On 26 December 1999, Chelsea became the first British side to field an entirely foreign starting line-up (no British or Irish players) in a Premier League match against Southampton. In May 2007, Chelsea were the first team to win the FA Cup at the new Wembley Stadium, having also been the last to win it at the old Wembley. They were the first English club to be ranked No. 1 under UEFA's five-year coefficient system in the 21st century. They were the first Premier League team, and the first team in the English top flight since 1962–63, to score at least 100 goals in a single season, reaching the milestone during the 2009–10 season. Chelsea are the only London club to win the UEFA Champions League. Upon winning the 2012–13 UEFA Europa League, Chelsea became the first English club to win all four UEFA club trophies and the only club to hold the Champions League and the Europa League at the same time. Chelsea have twice broken the record for the highest transfer fee paid by a British club. Their £30.8 million purchase of Andriy Shevchenko from A.C. Milan in June 2006 was a British record until surpassed by the £32.5 million paid by Manchester City for Robinho in September 2008. The club's £50 million purchase of Fernando Torres from Liverpool in January 2011 held the record until Ángel Di María signed for Manchester United in August 2014 for £59.7 million. The club's £71 million purchase of Kepa Arrizabalaga in August 2018 remains a world record fee paid for a goalkeeper. On the 12 February 2022, Chelsea became the first English club from London to win FIFA Club World Cup against Palmeiras with Kai Havertz scoring a late penalty. Ownership and finances Chelsea Football Club were founded by Gus Mears in 1905. After his death in 1912, his descendants continued to own the club until 1982, when Ken Bates bought the club from Mears' great-nephew Brian Mears for £1. Bates bought a controlling stake in the club and floated Chelsea on the AIM stock exchange in March 1996. In the mid-1990s Chelsea fan and businessman Matthew Harding became a director and loaned the club £26 million to build the new North Stand and invest in new players. In July 2003, Roman Abramovich purchased just over 50% of Chelsea Village plc's share capital, including Bates' 29.5% stake, for £30 million and over the following weeks bought out most of the remaining 12,000 shareholders at 35 pence per share, completing a £140 million takeover. Other shareholders at the time of the takeover included the Matthew Harding estate (21%), BSkyB (9.9%) and various anonymous offshore trusts. At the time of the Abramovich takeover, the club also had debts of around £100 million, which included a ten-year £75 million Eurobond taken out in 1997 by the Bates regime to buy the freehold of Stamford Bridge and finance the redevelopment of the stadium. The 9% interest on the loan cost the club around £7 million a year and according to Bruce Buck, Chelsea were struggling to pay an instalment due in July 2003. Abramovich paid off some of this debt immediately, but the outstanding £36 million on the Eurobond was not fully repaid until 2008. Since then, the club have had no external debt. Abramovich changed the ownership name to Chelsea FC plc, whose ultimate parent company is Fordstam Limited, which is controlled by him. Chelsea are additionally funded by Abramovich via interest free soft loans channelled through his holding company Fordstam Limited. The loans stood at £709 million in December 2009, when they were all converted to equity by Abramovich, leaving the club themselves debt free, although the debt remains with Fordstam. Chelsea did not turn a profit in the first nine years of Abramovich's ownership, and made record losses of £140m in June 2005. In November 2012, Chelsea announced a profit of £1.4 million for the year ending 30 June 2012, the first time the club had made a profit under Abramovich's ownership. This was followed by a loss in 2013 and then their highest ever profit of £18.4 million for the year to June 2014. In 2018 Chelsea announced a record after-tax profit of £62 million. Chelsea have been described as a global brand; a 2012 report by Brand Finance ranked Chelsea fifth among football brands and valued the club's brand value at US$398 million – an increase of 27% from the previous year, also valuing them at US$10 million more than the sixth best brand, London rivals Arsenal – and gave the brand a strength rating of AA (very strong). In 2016, Forbes magazine ranked Chelsea the seventh most valuable football club in the world, at £1.15 billion ($1.66 billion). , Chelsea are ranked eighth in the Deloitte Football Money League with an annual commercial revenue of £322.59 million. The club's recent accounting records highlight £26.6m they have lost in compensation to former head coach Antonio Conte for sacking and to pay off his backroom staff and the legal costs that followed. Sponsorship Chelsea's kit has been manufactured by Nike since July 2017. Previously, the kit was manufactured by Adidas, which was originally contracted to supply the club's kit from 2006 to 2018. The partnership was extended in October 2010 in a deal worth £160 million over eight years. This deal was again extended in June 2013 in a deal worth £300 million over another ten years. In May 2016, Adidas announced that by mutual agreement, the kit sponsorship would end six years early on 30 June 2017. Chelsea had to pay £40m in compensation to Adidas. In October 2016, Nike was announced as the new kit sponsor, in a deal worth £900m over 15 years, until 2032. Previously, the kit was manufactured by Umbro (1975–81), Le Coq Sportif (1981–86), The Chelsea Collection (1986–87), Umbro (1987–2006), and Adidas (2006–2017). Chelsea's first shirt sponsor was Gulf Air, agreed during the 1983–84 season. The club were then sponsored by Grange Farms, Bai Lin Tea and Simod before a long-term deal was signed with Commodore International in 1989; Amiga, an offshoot of Commodore, also appeared on the shirts. Chelsea were subsequently sponsored by Coors beer (1994–97), Autoglass (1997–2001), Emirates (2001–05), Samsung Mobile (2005–08), Samsung (2008–15). and Yokohama Tyres (2015–20). Chelsea's current sponsor is Three, starting from July 2020. Following the introduction of sleeve sponsors in the Premier League, Chelsea had Alliance Tyres as their first sleeve sponsor in

Four other players made more than 500 appearances for the club: Peter Bonetti (729; 1959–79), John Terry (717; 1998–2017), Frank Lampard (648; 2001–2014) and John Hollins (592; 1963–1975 and 1983–1984). With 103 caps (101 while at the club) for England, Lampard is Chelsea's most capped international player. Every starting player in Chelsea's 57 games of the 2013–14 season was a full international – a new club record. Lampard is Chelsea's all-time top goalscorer, having scored 211 goals in 648 games (2001–2014); he passed Bobby Tambling's longstanding record of 202 in May 2013. Eight other players have also scored over 100 goals for Chelsea: George Hilsdon (1906–1912), George Mills (1929–1939), Roy Bentley (1948–1956), Jimmy Greaves (1957–1961), Peter Osgood (1964–1974 and 1978–1979), Kerry Dixon (1983–1992), Didier Drogba (2004–2012 and 2014–2015), and Eden Hazard (2012–2019). Greaves holds the club record for the most goals scored in one season (43 in 1960–61). While a Chelsea player, Greaves also became the youngest ever player to score 100 goals in the English top-flight, at 20 years and 290 days. Chelsea's biggest winning scoreline in a competitive match is 13–0, achieved against Jeunesse Hautcharage in the Cup Winners' Cup in 1971. The club's biggest top-flight win was an 8–0 victory against Wigan Athletic in 2010, which was matched in 2012 against Aston Villa. Chelsea's biggest loss was an 8–1 reverse against Wolverhampton Wanderers in 1953. The club's 21–0 aggregate victory over Jeunesse Hautcharage in the UEFA Cup Winners' Cup in 1971 is also a record in European competition. Officially, Chelsea's highest home attendance is 82,905 for a First Division match against Arsenal on 12 October 1935. However, an estimated crowd of over 100,000 attended a friendly match against Soviet team Dynamo Moscow on 13 November 1945. From 20 March 2004 to 26 October 2008, Chelsea went a record 86 consecutive league matches at home without defeat, beating the previous record of 63 matches unbeaten set by Liverpool between 1978 and 1980. Chelsea hold the English record for the fewest goals conceded during a league season (15), the highest number of clean sheets overall in a Premier League season (25) (both set during the 2004–05 season), and the most consecutive clean sheets from the start of a league season (6, set during the 2005–06 season). Chelsea's streak of eleven consecutive away league wins, set between 5 April 2008 and 6 December 2008, is a record for the English top flight. Chelsea are the only Premier League side to win their opening nine league games of the season, doing so in 2005–06. From 2009 to 2013, Chelsea were unbeaten in a record 29 consecutive FA Cup matches (excluding penalty shoot-outs). On 25 August 1928, Chelsea, along with Arsenal, became the first club to play with shirt numbers, in their match against Swansea Town. They were the first English side to travel by aeroplane to a domestic away match, when they visited Newcastle United on 19 April 1957, and the first First Division side to play a match on a Sunday, when they faced Stoke City on 27 January 1974. On 26 December 1999, Chelsea became the first British side to field an entirely foreign starting line-up (no British or Irish players) in a Premier League match against Southampton. In May 2007, Chelsea were the first team to win the FA Cup at the new Wembley Stadium, having also been the last to win it at the old Wembley. They were the first English club to be ranked No. 1 under UEFA's five-year coefficient system in the 21st century. They were the first Premier League team, and the first team in the English top flight since 1962–63, to score at least 100 goals in a single season, reaching the milestone during the 2009–10 season. Chelsea are the only London club to win the UEFA Champions League. Upon winning the 2012–13 UEFA Europa League, Chelsea became the first English club to win all four UEFA club trophies and the only club to hold the Champions League and the Europa League at the same time. Chelsea have twice broken the record for the highest transfer fee paid by a British club. Their £30.8 million purchase of Andriy Shevchenko from A.C. Milan in June 2006 was a British record until surpassed by the £32.5 million paid by Manchester City for Robinho in September 2008. The club's £50 million purchase of Fernando Torres from Liverpool in January 2011 held the record until Ángel Di María signed for Manchester United in August 2014 for £59.7 million. The club's £71 million purchase of Kepa Arrizabalaga in August 2018 remains a world record fee paid for a goalkeeper. On the 12 February 2022, Chelsea became the first English club from London to win FIFA Club World Cup against Palmeiras with Kai Havertz scoring a late penalty. Ownership and finances Chelsea Football Club were founded by Gus Mears in 1905. After his death in 1912, his descendants continued to own the club until 1982, when Ken Bates bought the club from Mears' great-nephew Brian Mears for £1. Bates bought a controlling stake in the club and floated Chelsea on the AIM stock exchange in March 1996. In the mid-1990s Chelsea fan and businessman Matthew Harding became a director and loaned the club £26 million to build the new North Stand and invest in new players. In July 2003, Roman Abramovich purchased just over 50% of Chelsea Village plc's share capital, including Bates' 29.5% stake, for £30 million and over the following weeks bought out most of the remaining 12,000 shareholders at 35 pence per share, completing a £140 million takeover. Other shareholders at the time of the takeover included the Matthew Harding estate (21%), BSkyB (9.9%) and various anonymous offshore trusts. At the time of the Abramovich takeover, the club also had debts of around £100 million, which included a ten-year £75 million Eurobond taken out in 1997 by the Bates regime to buy the freehold of Stamford Bridge and finance the redevelopment of the stadium. The 9% interest on the loan cost the club around £7 million a year and according to Bruce Buck, Chelsea were struggling to pay an instalment due in July 2003. Abramovich paid off some of this debt immediately, but the outstanding £36 million on the Eurobond was not fully repaid until 2008. Since then, the club have had no external debt. Abramovich changed the ownership name to Chelsea FC plc, whose ultimate parent company is Fordstam Limited, which is controlled by him. Chelsea are additionally funded by Abramovich via interest free soft loans channelled through his holding company Fordstam Limited. The loans stood at £709 million in December 2009, when they were all converted to equity by Abramovich, leaving the club themselves debt free, although the debt remains with Fordstam. Chelsea did not turn a profit in the first nine years of Abramovich's ownership, and made record losses of £140m in June 2005. In November 2012, Chelsea announced a profit of £1.4 million for the year ending 30 June 2012, the first time the club had made a profit under Abramovich's ownership. This was followed by a loss in 2013 and then their highest ever profit of £18.4 million for the year to June 2014. In 2018 Chelsea announced a record after-tax profit of £62 million. Chelsea have been described as a global brand; a 2012 report by Brand Finance ranked Chelsea fifth among football brands and valued the club's brand value at US$398 million – an increase of 27% from the previous year, also valuing them at US$10 million more than the sixth best brand, London rivals Arsenal – and gave the brand a strength rating of AA (very strong). In 2016, Forbes magazine ranked Chelsea the seventh most valuable football club in the world, at £1.15 billion ($1.66 billion). , Chelsea are ranked eighth in the Deloitte Football Money League with an annual commercial revenue of £322.59 million. The club's recent accounting records highlight £26.6m they have lost in compensation to former head coach Antonio Conte for sacking and to pay off his backroom staff and the legal costs that followed. Sponsorship Chelsea's kit has been manufactured by Nike since July 2017. Previously, the kit was manufactured by Adidas, which was originally contracted to supply the club's kit from 2006 to 2018. The partnership was extended in October 2010 in a deal worth £160 million over eight years. This deal was again extended in June 2013 in a deal worth £300 million over another ten years. In May 2016, Adidas announced that by mutual agreement, the kit sponsorship would end six years early on 30 June 2017. Chelsea had to pay £40m in compensation to Adidas. In October 2016, Nike was announced as the new kit sponsor, in a deal worth £900m over 15 years, until 2032. Previously, the kit was manufactured by Umbro (1975–81), Le Coq Sportif (1981–86), The Chelsea Collection (1986–87), Umbro (1987–2006), and Adidas (2006–2017). Chelsea's first shirt sponsor was Gulf Air, agreed during the 1983–84 season. The club were then sponsored by Grange Farms, Bai Lin Tea and Simod before a long-term deal was signed with Commodore International in 1989; Amiga, an offshoot of Commodore, also appeared on the shirts. Chelsea were subsequently sponsored by Coors beer (1994–97), Autoglass (1997–2001), Emirates (2001–05), Samsung Mobile (2005–08), Samsung (2008–15). and Yokohama Tyres (2015–20). Chelsea's current sponsor is Three, starting from July 2020. Following the introduction of sleeve sponsors in the Premier League, Chelsea had Alliance Tyres as their first sleeve sponsor in the 2017–18 season. For the 2018–19 season, they have Hyundai Motor Company as the new sleeve sponsor. The club also has a variety of other sponsors and official partners, which include Bangkok Bank, Beats by Dre, Cadbury, Carabao, Delta Air Lines, EA Sports, Ericsson, Fiserv, Gazprom, GO Markets, Grand Royal Whisky, Guangzhou R&F, Hublot, IndusInd Bank, Levy Restaurants, Millennium Hotels, MSC Cruises, Mobinil, Ole777, Parimatch, Rexona, Singha, Sony Music, Trivago, Vitality, William Hill, Wipro, and Zapp. Kit suppliers and shirt sponsors Popular culture In 1930, Chelsea featured in one of the earliest football films, The Great Game. One-time Chelsea centre forward, Jack Cock, who by then was playing for Millwall, was the star of the film and several scenes were shot at Stamford Bridge, including on the pitch, the boardroom, and the dressing rooms. It included guest appearances by then-Chelsea players Andrew Wilson, George Mills, and Sam Millington. Owing to the notoriety of the Chelsea Headhunters, a football firm associated with the club, Chelsea have also featured in films about football hooliganism, including 2004's The Football Factory. Chelsea also appear in the Hindi film Jhoom Barabar Jhoom. In April 2011, Montenegrin comedy series Nijesmo mi od juče made an episode in which Chelsea play against FK Sutjeska Nikšić for qualification of the UEFA Champions League. Up until the 1950s, the club had a long-running association with the music halls; their underachievement often provided material for comedians such as George Robey. It culminated in comedian Norman Long's release of a comic song in 1933, ironically titled "On the Day That Chelsea Went and Won the Cup", the lyrics of which describe a series of bizarre and improbable occurrences on the hypothetical day when Chelsea finally won a trophy. In Alfred Hitchcock's 1935 film The 39 Steps, Mr Memory claims that Chelsea last won the Cup in 63 BC, "in the presence of the Emperor Nero." Scenes in a 1980 episode of Minder were filmed during a real match at Stamford Bridge between Chelsea and Preston North End with Terry McCann (played by Dennis Waterman) standing on the terraces. The song "Blue is the Colour" was released as a single in the build-up to the 1972 League Cup Final, with all members of Chelsea's first team squad singing; it reached number five in the UK Singles Chart. The song has since been adopted as an anthem by a number of other sports teams around the world, including the Vancouver Whitecaps (as "White is the Colour") and the Saskatchewan Roughriders (as "Green is the Colour"). In the build-up to the 1997 FA Cup Final, the song "Blue Day", performed by Suggs and members of the Chelsea squad, reached number 22 in the UK charts. Chelsea Women Chelsea also operate a women's football team, Chelsea Football Club Women, formerly known as Chelsea Ladies. They have been affiliated to the men's team since 2004 and are part of the club's Community Development programme. They play their home games at Kingsmeadow, formerly the home ground of the EFL League One club AFC Wimbledon. The club were promoted to the Premier Division for the first time in 2005 as Southern Division champions and won the Surrey County Cup nine times between 2003 and 2013. In 2010 Chelsea Ladies were one of the eight founder members of the FA Women's Super League. In 2015, Chelsea Ladies won the FA Women's Cup for the first time, beating Notts County Ladies at Wembley Stadium, and a month later clinched their first FA WSL title to complete a league and cup double. In 2018, they won a second league and FA Cup double. Two years later in 2020,
overall price per kWh electricity is comparable. The next-generation Advanced CANDU reactor (ACR) mitigates these disadvantages by having light-water coolant and using a more compact core with less moderator. When first introduced, CANDUs offered much better capacity factor (ratio of power generated to what would be generated by running at full power, 100% of the time) than LWRs of a similar generation. The light-water designs spent, on average, about half the time being refueled or maintained. Since the 1980s, dramatic improvements in LWR outage management have narrowed the gap, with several units achieving capacity factors ~90% and higher, with an overall fleet performance of 92% in 2010. The latest-generation CANDU 6 reactors have an 88–90% CF, but overall performance is dominated by the older Canadian units with CFs on the order of 80%. Refurbished units had historically demonstrated poor performance, on the order of 65%. This has since improved with the return of Bruce units A1 and A2 to operation, which have post-refurbishment capacity factors of 82% and 88%, respectively. Some CANDU plants suffered from cost overruns during construction, often from external factors such as government action. For instance, a number of imposed construction delays led to roughly a doubling of the cost of the Darlington Nuclear Generating Station near Toronto, Ontario. Technical problems and redesigns added about another billion to the resulting $14.4 billion price. In contrast, in 2002 two CANDU 6 reactors at Qinshan in China were completed on-schedule and on-budget, an achievement attributed to tight control over scope and schedule. Nuclear nonproliferation In terms of safeguards against nuclear weapons proliferation, CANDUs meet a similar level of international certification as other reactors. The plutonium for India's first nuclear detonation, Operation Smiling Buddha in 1974, was produced in a CIRUS reactor supplied by Canada and partially paid for by the Canadian government using heavy water supplied by the United States. In addition to its two PHWR reactors, India has some safeguarded pressurised heavy-water reactors (PHWRs) based on the CANDU design, and two safeguarded light-water reactors supplied by the US. Plutonium has been extracted from the spent fuel from all of these reactors; India mainly relies on an Indian designed and built military reactor called Dhruva. The design is believed to be derived from the CIRUS reactor, with the Dhruva being scaled-up for more efficient plutonium production. It is this reactor which is thought to have produced the plutonium for India's more recent (1998) Operation Shakti nuclear tests. Although heavy water is relatively immune to neutron capture, a small amount of the deuterium turns into tritium in this way. This tritium is extracted from some CANDU plants in Canada, mainly to improve safety in case of heavy-water leakage. The gas is stockpiled and used in a variety of commercial products, notably "powerless" lighting systems and medical devices. In 1985 what was then Ontario Hydro sparked controversy in Ontario due to its plans to sell tritium to the United States. The plan, by law, involved sales to non-military applications only, but some speculated that the exports could have freed American tritium for the United States nuclear weapons program. Future demands appear to outstrip production, in particular the demands of future generations of experimental fusion reactors like ITER. Between of tritium were recovered annually at the Darlington separation facility by 2003, of which a minor fraction was sold. The 1998 Operation Shakti test series in India included one bomb of about yield that India has publicly claimed was a hydrogen bomb. An offhand comment in the BARC publication Heavy Water – Properties, Production and Analysis appears to suggest that the tritium was extracted from the heavy water in the CANDU and PHWR reactors in commercial operation. Janes Intelligence Review quotes the Chairman of the Indian Atomic Energy Commission as admitting to the tritium extraction plant, but refusing to comment on its use. India is also capable of creating tritium more efficiently by irradiation of lithium-6 in reactors. Tritium production Tritium, 3H, is a radioactive isotope of hydrogen, with a half-life of 12.3 years. It is produced in small amounts in nature (about 4 kg per year globally) by cosmic ray interactions in the upper atmosphere. Tritium is considered a weak radionuclide because of its low-energy radioactive emissions (beta particle energy up to 18.6 keV). The beta particles travel 6 mm in air and only penetrate skin up to 6 micrometers. The biological half-life of inhaled, ingested, or absorbed tritium is 10–12 days. Tritium is generated in the fuel of all reactors; CANDU reactors generate tritium also in their coolant and moderator, due to neutron capture in heavy hydrogen. Some of this tritium escapes into containment and is generally recovered; a small percentage (about 1%) escapes containment and is considered a routine radioactive emission (also higher than from an LWR of comparable size). Responsible operation of a CANDU plant therefore includes monitoring tritium in the surrounding environment (and publishing the results). In some CANDU reactors the tritium is periodically extracted. Typical emissions from CANDU plants in Canada are less than 1% of the national regulatory limit, which is based on International Commission on Radiological Protection (ICRP) guidelines (for example, the maximal permitted drinking-water concentration for tritium in Canada, 7,000 Bq/L, corresponds to 1/10 of the ICRP's dose limit for members of the public). Tritium emissions from other CANDU plants are similarly low. In general, there is significant public controversy about radioactive emissions from nuclear power plants, and for CANDU plants one of the main concerns is tritium. In 2007 Greenpeace published a critique of tritium emissions from Canadian nuclear power plants by Ian Fairlie. This report was criticized by Richard Osborne. History The CANDU development effort has gone through four major stages over time. The first systems were experimental and prototype machines of limited power. These were replaced by a second generation of machines of 500 to 600 MWe (the CANDU 6), a series of larger machines of 900 MWe, and finally developing into the CANDU 9 and ACR-1000 effort. Early efforts The first heavy-water-moderated design in Canada was the ZEEP, which started operation just after the end of World War II. ZEEP was joined by several other experimental machines, including the NRX in 1947 and NRU in 1957. These efforts led to the first CANDU-type reactor, the Nuclear Power Demonstration (NPD), in Rolphton, Ontario. It was intended as a proof-of-concept and rated for only 22 MWe, a very low power for a commercial power reactor. NPD produced the first nuclear-generated electricity in Canada and ran successfully from 1962 to 1987. The second CANDU was the Douglas Point reactor, a more powerful version rated at roughly 200 MWe and located near Kincardine, Ontario. It went into service in 1968 and ran until 1984. Uniquely among CANDU stations, Douglas Point had an oil-filled window with a view of the east reactor face, even when the reactor was operating. Douglas Point was originally planned to be a two-unit station, but the second unit was cancelled because of the success of the larger 515 MWe units at Pickering. Gentilly-1, in Bécancour, Quebec near Trois-Rivières, Quebec, was also an experimental version of CANDU, using a boiling light-water coolant and vertical pressure tubes, but was not considered successful and closed after seven years of fitful operation. Gentilly-2, a CANDU-6 reactor, began operating in 1983. Following statements from the in-coming Parti Québécois government in September 2012 that Gentilly would close, the operator, Hydro-Québec, decided to cancel a previously announced refurbishment of the plant and announced its shutdown at the end of 2012, citing economic reasons for the decision. The company has started a 50-year decommissioning process estimated to cost $1.8 billion. In parallel with the classic CANDU design, experimental variants were being developed. WR-1, located at the AECL's Whiteshell Laboratories in Pinawa, Manitoba, used vertical pressure tubes and organic oil as the primary coolant. The oil used has a higher boiling point than water, allowing the reactor to operate at higher temperatures and lower pressures than a conventional reactor. WR-1's outlet temperature was about 490 °C compared to the CANDU 6's nominal 310 °C; the higher temperature and thus thermodynamic efficiency offsets to some degree the fact that oils have about half the heat capacity of water. The higher temperatures also result in more efficient conversion to steam, and ultimately, electricity. WR-1 operated successfully for many years and promised a significantly higher efficiency than water-cooled versions. 600 MWe designs The successes at NPD and Douglas Point led to the decision to construct the first multi-unit station in Pickering, Ontario. Pickering A, consisting of Units 1 to 4, went into service in 1971. Pickering B with units 5 to 8 came online in 1983, giving a full-station capacity of 4,120 MWe. The station is very close to the city of Toronto, in order to reduce transmission costs. A series of improvements to the basic Pickering design led to the CANDU 6 design, which first went into operation in the early 1980s. CANDU 6 was essentially a version of the Pickering power plant that was redesigned to be able to be built in single-reactor units. CANDU 6 was used in several installations outside Ontario, including the Gentilly-2 in Quebec, and Point Lepreau Nuclear Generating Station in New Brunswick. CANDU 6 forms the majority of foreign CANDU systems, including the designs exported to Argentina, Romania, China and South Korea. Only India operates a CANDU system that is not based on the CANDU 6 design. 900 MWe designs The economics of nuclear power plants generally scale well with size. This improvement at larger sizes is offset by the sudden appearance of large quantities of power on the grid, which leads to a lowering of electricity prices through supply and demand effects. Predictions in the late 1960s suggested that growth in electricity demand would overwhelm these downward pricing pressures, leading most designers to introduce plants in the 1000 MWe range. Pickering A was quickly followed by such an upscaling effort for the Bruce Nuclear Generating Station, constructed in stages between 1970 and 1987. It is the largest nuclear facility in North America and second largest in the world (after Kashiwazaki-Kariwa in Japan), with eight reactors at around 800 MWe each, in total 6,232 MW (net) and 7,276 MW (gross). Another, smaller, upscaling led to the Darlington Nuclear Generating Station design, similar to the Bruce plant, but delivering about 880 MWe per reactor in a four-reactor station. As was the case for the development of the Pickering design into the CANDU 6, the Bruce design was also developed into the similar CANDU 9. Like the CANDU 6, the CANDU 9 is essentially a repackaging of the Bruce design, so that it can be built as a single-reactor unit. No CANDU 9 reactors have been built. Generation III+ designs Through the 1980s and 1990s the nuclear power market suffered a major crash, with few new plants being constructed in North America or Europe. Design work continued throughout, and new design concepts were introduced that dramatically improved safety, capital costs, economics and overall performance. These generation III+ and generation IV machines became a topic of considerable interest in the early 2000s, as it appeared that a nuclear renaissance was underway and large numbers of new reactors would be built over the next decade. AECL had been working on a design known as the ACR-700, using elements of the latest versions of the CANDU 6 and CANDU 9, with a design power of 700 MWe. During the nuclear renaissance, the upscaling seen in the earlier years re-expressed itself, and the ACR-700 was developed into the 1200 MWe ACR-1000. ACR-1000 is the next-generation (officially, "generation III+") CANDU technology, which makes some significant modifications to the existing CANDU design. The main change, and the most radical among the CANDU generations, is the use of pressurized light water as the coolant. This significantly reduces the cost of implementing the primary cooling loop, which no longer has to be filled with expensive heavy water. The ACR-1000 uses about 1/3rd the heavy water needed in earlier-generation designs. It also eliminates tritium production in the coolant loop, the major source of tritium leaks in operational CANDU designs. The redesign also allows a slightly negative void reactivity, a major design goal of all Gen III+ machines. The design also requires the use of slightly enriched uranium, enriched by about 1 or 2%. The main reason for this is to increase the burn-up ratio, allowing bundles to remain in the reactor longer, so that only a third as much spent fuel is produced. This also has effects on operational costs and timetables, as the refuelling frequency is reduced. As is the case with earlier CANDU designs, the ACR-1000 also offers online refuelling. Outside of the reactor, the ACR-1000 has a number of design changes that are expected to dramatically lower capital and operational costs. Primary among these changes is the design lifetime of 60 years, which dramatically lowers the price of the electricity generated over the lifetime of the plant. The design also has an expected capacity factor of 90%. Higher-pressure steam generators and turbines improve efficiency downstream of the reactor. Many of the operational design changes were also applied to the existing CANDU 6 to produce the Enhanced CANDU 6. Also known as CANDU 6e or EC 6, this was an evolutionary upgrade of the CANDU 6 design with a gross output of 740 MWe per unit. The reactors are designed with a lifetime of over 50 years, with a mid-life program to replace some of the key components e.g. the fuel channels. The projected average annual capacity factor is more than 90%. Improvements to construction techniques (including modular, open-top assembly) decrease construction costs. The CANDU 6e is designed to operate at power settings as low as 50%, allowing them to adjust to load demand much better than the previous designs. Sales efforts in Canada By most measures, the CANDU is "the Ontario reactor". The system was developed almost entirely in Ontario, and only two experimental designs were built in other provinces. Of the 29 commercial CANDU reactors built, 22 are in Ontario. Of these 22, a number of reactors have been removed from service. Two new CANDU reactors have been proposed for Darlington with Canadian government help with financing, but these plans ended in 2009 due to high costs. AECL has heavily marketed CANDU within Canada, but has found a limited reception. To date, only two non-experimental reactors have been built in other provinces, one each in Quebec and New Brunswick, other provinces have concentrated on hydro and coal-fired plants. Several Canadian provinces have developed large amounts of hydro power. Alberta and Saskatchewan do not have extensive hydro resources, and use mainly fossil fuels to generate electric power. Interest has been expressed in Western Canada, where CANDU reactors are being considered as heat and electricity sources for the energy-intensive oil sands extraction process, which currently uses natural gas. Energy Alberta Corporation announced 27 August 2007 that they had applied for a licence to build a new nuclear plant at Lac Cardinal (30 km west of the town of Peace River, Alberta), with two ACR-1000 reactors going online in 2017 producing 2.2 gigawatts (electric). A 2007 parliamentary review suggested placing the development efforts on hold. The company was later purchased by Bruce Power, who proposed expanding the plant to four units of a total 4.4 gigawatts. These plans were upset and Bruce later withdrew its application for the Lac Cardinal, proposing instead a new site about 60 km away. The plans are currently moribund after a wide consultation with the public demonstrated that while about of the population were open to reactors, were opposed. Foreign sales During the 1970s, the international nuclear sales market was extremely competitive, with many national nuclear companies being supported by their governments' foreign embassies. In addition, the pace of construction in the United States had meant that cost overruns and delayed completion was generally over, and subsequent reactors would be cheaper. Canada, a relatively new player on the international market, had numerous disadvantages in these efforts. The CANDU was deliberately designed to reduce the need for very large machined parts, making it suitable for construction by countries without a major industrial base. Sales efforts have had their most success in countries that could not locally build designs from other firms. In the late 1970s, AECL noted that each reactor sale would employ 3,600 Canadians and result in $300 million in balance-of-payments income. These sales efforts were aimed primarily at countries being run by dictatorships or similar, a fact that led to serious concerns in parliament. These efforts also led to a scandal when it was discovered millions of dollars had been given to foreign sales agents, with little or no record of who they were, or what they did to earn the money. This led to a Royal Canadian Mounted Police investigation after questions were raised about sales efforts in Argentina, and new regulations on full disclosure of fees for future sales. CANDU's first success was the sale of early CANDU designs to India. In 1963, an agreement was signed for export of a 200 MWe power reactor based on the Douglas Point reactor. The success of the deal led to the 1966 sale of a second reactor of the same design. The first reactor, then known as RAPP-1 for "Rajasthan Atomic Power Project", began operation in 1972. A serious problem with cracking of the reactor's end shield led to the reactor being shut down for long periods, and the reactor was finally downrated to 100 MW. Construction of the RAPP-2 reactor was still underway when India detonated its first atomic bomb in 1974, leading to Canada ending nuclear dealings with the country. Part of the sales agreement was a technology transfer process. When Canada withdrew from development, India continued construction of CANDU-like plants across the country. By 2010, CANDU-based reactors were operational at the following sites: Kaiga (3), Kakrapar (2), Madras (2), Narora (2), Rajasthan (6), and Tarapur (2). In Pakistan, the Karachi Nuclear Power Plant with a gross capacity of 137 MWe was built between 1966 and 1971. In 1972, AECL submitted a design based on the Pickering plant to Argentina's Comision Nacional de Energia Atomica process, in partnership with the Italian company Italimpianti. High inflation during construction led to massive losses, and efforts to re-negotiate the deal were interrupted by the March 1976 coup led by General Videla. The Embalse Nuclear Power Station began commercial operation in January 1984. There have been ongoing negotiations to open more CANDU 6 reactors in the country, including a 2007 deal between Canada, China and Argentina, but to date no firm plans have been announced. A licensing agreement with Romania was signed in 1977, selling the CANDU 6 design for $5 million per reactor for the first four reactors, and then $2 million each for the next twelve. In addition, Canadian companies would supply a varying amount of equipment for the reactors, about $100 million of the first reactor's $800 million price tag, and then falling over time. In 1980, Nicolae Ceaușescu asked for a modification to provide goods instead of cash, in exchange the amount of Canadian content was increased and a second reactor would be built with Canadian help. Economic troubles in the country worsened throughout the construction phase. The first reactor of the Cernavodă Nuclear Power Plant only came online in April 1996, a decade after its December 1985 predicted startup. Further loans were arranged for completion of the second reactor, which went online in November 2007. In January 1975, a deal was announced for a single CANDU 6 reactor to be built in South Korea, now known as the Wolsong-1 Power Reactor. Construction started in 1977 and commercial operation began in April 1983. In December 1990 a further deal was announced for three additional units at the same site, which began operation in the period 1997–1999. South Korea also negotiated development and technology transfer deals with Westinghouse for their advanced System-80 reactor design, and all future development is based on locally built versions of this reactor. In June 1998, construction started on a CANDU 6 reactor in Qinshan China Qinshan Nuclear Power Plant, as Phase III (units 4 and 5) of the planned 11 unit facility. Commercial operation began in December 2002 and July 2003, respectively. These are the first heavy water reactors in China. Qinshan is the first CANDU-6 project to use open-top reactor building construction, and the first project where commercial operation began earlier than the projected date. CANDU Energy is continuing marketing efforts in China. In addition, China and Argentina have agreed a contract to build a 700 MWe Candu-6 derived reactor. Construction is planned to start in 2018 at Atucha. Economic performance The cost of electricity from any power plant can be calculated by roughly the same selection of factors: capital costs for construction or the payments on loans made to secure that capital, the cost of fuel on a per-watt-hour basis, and fixed and variable maintenance fees. In the case of nuclear power, one normally includes two additional costs, the cost of permanent waste disposal, and the cost of decommissioning the plant when its useful lifetime is over. Generally, the capital costs dominate the price of nuclear power, as the amount of power produced is so large that it overwhelms the cost of fuel and maintenance. The World Nuclear Association calculates that the cost of fuel, including all processing, accounts for less than one cent (US$0.01) per kWh. Information on economic performance on CANDU is somewhat lopsided; the majority of reactors are in Ontario, which is also the "most public" among the major CANDU operators. Although much attention has been focused on the problems with the Darlington plant, every CANDU design in Ontario went over budget by at least 25%, and average over 150% higher than estimated. Darlington was the worst, at 350% over budget, but this project was stopped in-progress
temperature and thus thermodynamic efficiency offsets to some degree the fact that oils have about half the heat capacity of water. The higher temperatures also result in more efficient conversion to steam, and ultimately, electricity. WR-1 operated successfully for many years and promised a significantly higher efficiency than water-cooled versions. 600 MWe designs The successes at NPD and Douglas Point led to the decision to construct the first multi-unit station in Pickering, Ontario. Pickering A, consisting of Units 1 to 4, went into service in 1971. Pickering B with units 5 to 8 came online in 1983, giving a full-station capacity of 4,120 MWe. The station is very close to the city of Toronto, in order to reduce transmission costs. A series of improvements to the basic Pickering design led to the CANDU 6 design, which first went into operation in the early 1980s. CANDU 6 was essentially a version of the Pickering power plant that was redesigned to be able to be built in single-reactor units. CANDU 6 was used in several installations outside Ontario, including the Gentilly-2 in Quebec, and Point Lepreau Nuclear Generating Station in New Brunswick. CANDU 6 forms the majority of foreign CANDU systems, including the designs exported to Argentina, Romania, China and South Korea. Only India operates a CANDU system that is not based on the CANDU 6 design. 900 MWe designs The economics of nuclear power plants generally scale well with size. This improvement at larger sizes is offset by the sudden appearance of large quantities of power on the grid, which leads to a lowering of electricity prices through supply and demand effects. Predictions in the late 1960s suggested that growth in electricity demand would overwhelm these downward pricing pressures, leading most designers to introduce plants in the 1000 MWe range. Pickering A was quickly followed by such an upscaling effort for the Bruce Nuclear Generating Station, constructed in stages between 1970 and 1987. It is the largest nuclear facility in North America and second largest in the world (after Kashiwazaki-Kariwa in Japan), with eight reactors at around 800 MWe each, in total 6,232 MW (net) and 7,276 MW (gross). Another, smaller, upscaling led to the Darlington Nuclear Generating Station design, similar to the Bruce plant, but delivering about 880 MWe per reactor in a four-reactor station. As was the case for the development of the Pickering design into the CANDU 6, the Bruce design was also developed into the similar CANDU 9. Like the CANDU 6, the CANDU 9 is essentially a repackaging of the Bruce design, so that it can be built as a single-reactor unit. No CANDU 9 reactors have been built. Generation III+ designs Through the 1980s and 1990s the nuclear power market suffered a major crash, with few new plants being constructed in North America or Europe. Design work continued throughout, and new design concepts were introduced that dramatically improved safety, capital costs, economics and overall performance. These generation III+ and generation IV machines became a topic of considerable interest in the early 2000s, as it appeared that a nuclear renaissance was underway and large numbers of new reactors would be built over the next decade. AECL had been working on a design known as the ACR-700, using elements of the latest versions of the CANDU 6 and CANDU 9, with a design power of 700 MWe. During the nuclear renaissance, the upscaling seen in the earlier years re-expressed itself, and the ACR-700 was developed into the 1200 MWe ACR-1000. ACR-1000 is the next-generation (officially, "generation III+") CANDU technology, which makes some significant modifications to the existing CANDU design. The main change, and the most radical among the CANDU generations, is the use of pressurized light water as the coolant. This significantly reduces the cost of implementing the primary cooling loop, which no longer has to be filled with expensive heavy water. The ACR-1000 uses about 1/3rd the heavy water needed in earlier-generation designs. It also eliminates tritium production in the coolant loop, the major source of tritium leaks in operational CANDU designs. The redesign also allows a slightly negative void reactivity, a major design goal of all Gen III+ machines. The design also requires the use of slightly enriched uranium, enriched by about 1 or 2%. The main reason for this is to increase the burn-up ratio, allowing bundles to remain in the reactor longer, so that only a third as much spent fuel is produced. This also has effects on operational costs and timetables, as the refuelling frequency is reduced. As is the case with earlier CANDU designs, the ACR-1000 also offers online refuelling. Outside of the reactor, the ACR-1000 has a number of design changes that are expected to dramatically lower capital and operational costs. Primary among these changes is the design lifetime of 60 years, which dramatically lowers the price of the electricity generated over the lifetime of the plant. The design also has an expected capacity factor of 90%. Higher-pressure steam generators and turbines improve efficiency downstream of the reactor. Many of the operational design changes were also applied to the existing CANDU 6 to produce the Enhanced CANDU 6. Also known as CANDU 6e or EC 6, this was an evolutionary upgrade of the CANDU 6 design with a gross output of 740 MWe per unit. The reactors are designed with a lifetime of over 50 years, with a mid-life program to replace some of the key components e.g. the fuel channels. The projected average annual capacity factor is more than 90%. Improvements to construction techniques (including modular, open-top assembly) decrease construction costs. The CANDU 6e is designed to operate at power settings as low as 50%, allowing them to adjust to load demand much better than the previous designs. Sales efforts in Canada By most measures, the CANDU is "the Ontario reactor". The system was developed almost entirely in Ontario, and only two experimental designs were built in other provinces. Of the 29 commercial CANDU reactors built, 22 are in Ontario. Of these 22, a number of reactors have been removed from service. Two new CANDU reactors have been proposed for Darlington with Canadian government help with financing, but these plans ended in 2009 due to high costs. AECL has heavily marketed CANDU within Canada, but has found a limited reception. To date, only two non-experimental reactors have been built in other provinces, one each in Quebec and New Brunswick, other provinces have concentrated on hydro and coal-fired plants. Several Canadian provinces have developed large amounts of hydro power. Alberta and Saskatchewan do not have extensive hydro resources, and use mainly fossil fuels to generate electric power. Interest has been expressed in Western Canada, where CANDU reactors are being considered as heat and electricity sources for the energy-intensive oil sands extraction process, which currently uses natural gas. Energy Alberta Corporation announced 27 August 2007 that they had applied for a licence to build a new nuclear plant at Lac Cardinal (30 km west of the town of Peace River, Alberta), with two ACR-1000 reactors going online in 2017 producing 2.2 gigawatts (electric). A 2007 parliamentary review suggested placing the development efforts on hold. The company was later purchased by Bruce Power, who proposed expanding the plant to four units of a total 4.4 gigawatts. These plans were upset and Bruce later withdrew its application for the Lac Cardinal, proposing instead a new site about 60 km away. The plans are currently moribund after a wide consultation with the public demonstrated that while about of the population were open to reactors, were opposed. Foreign sales During the 1970s, the international nuclear sales market was extremely competitive, with many national nuclear companies being supported by their governments' foreign embassies. In addition, the pace of construction in the United States had meant that cost overruns and delayed completion was generally over, and subsequent reactors would be cheaper. Canada, a relatively new player on the international market, had numerous disadvantages in these efforts. The CANDU was deliberately designed to reduce the need for very large machined parts, making it suitable for construction by countries without a major industrial base. Sales efforts have had their most success in countries that could not locally build designs from other firms. In the late 1970s, AECL noted that each reactor sale would employ 3,600 Canadians and result in $300 million in balance-of-payments income. These sales efforts were aimed primarily at countries being run by dictatorships or similar, a fact that led to serious concerns in parliament. These efforts also led to a scandal when it was discovered millions of dollars had been given to foreign sales agents, with little or no record of who they were, or what they did to earn the money. This led to a Royal Canadian Mounted Police investigation after questions were raised about sales efforts in Argentina, and new regulations on full disclosure of fees for future sales. CANDU's first success was the sale of early CANDU designs to India. In 1963, an agreement was signed for export of a 200 MWe power reactor based on the Douglas Point reactor. The success of the deal led to the 1966 sale of a second reactor of the same design. The first reactor, then known as RAPP-1 for "Rajasthan Atomic Power Project", began operation in 1972. A serious problem with cracking of the reactor's end shield led to the reactor being shut down for long periods, and the reactor was finally downrated to 100 MW. Construction of the RAPP-2 reactor was still underway when India detonated its first atomic bomb in 1974, leading to Canada ending nuclear dealings with the country. Part of the sales agreement was a technology transfer process. When Canada withdrew from development, India continued construction of CANDU-like plants across the country. By 2010, CANDU-based reactors were operational at the following sites: Kaiga (3), Kakrapar (2), Madras (2), Narora (2), Rajasthan (6), and Tarapur (2). In Pakistan, the Karachi Nuclear Power Plant with a gross capacity of 137 MWe was built between 1966 and 1971. In 1972, AECL submitted a design based on the Pickering plant to Argentina's Comision Nacional de Energia Atomica process, in partnership with the Italian company Italimpianti. High inflation during construction led to massive losses, and efforts to re-negotiate the deal were interrupted by the March 1976 coup led by General Videla.

June 30, 1520. Some sources claim he was serving in that role even before Moctezuma's death. Cuitláhuac was ritually married to Moctezuma's eldest daughter, a ten- or eleven-year-old girl, who later was called Isabel Moctezuma. Cuitláhuac ruled just 80 days, perhaps dying from smallpox that had been introduced to the New World by an African suffering from the disease who was part of Pánfilo de Narváez's expedition to capture Cortés. The early sources do not explicitly say from what he succumbed. Immediately after Cuitláhuac's death, Cuauhtémoc was made the next tlatoani. Legacy The modern Mexican municipality of Cuitláhuac, Veracruz and the Mexico City Metro station Metro Cuitláhuac are named in honor of Cuitláhuac.

his experiences in his book The True History of the Conquest of New Spain, the supposed plot was revealed by two men, named Tapia and Juan Velásquez. Díaz portrays the executions as unjust and based on no evidence, and he admits to having liked Cuauhtémoc personally. He also records Cuauhtémoc giving the following speech to Cortés through his interpreter Malinche: Díaz wrote that afterwards, Cortés suffered from insomnia because of guilt and badly injured himself while he was wandering at night. Fernando de Alva Cortés Ixtlilxóchitl, a castizo historian and descendant of Coanacoch, wrote an account of the executions in the 17th century partly based on Texcocan oral tradition. According to Ixtlilxóchitl, the three lords were joking cheerfully with one another because of a rumor that Cortés had decided to return the expedition to Mexico, when Cortés asked a spy to tell him what they were talking about. The spy reported honestly, but Cortés invented the plot himself. Cuauhtémoc, Coanacoch, and Tetlepanquetzal were hanged as well as eight others. However, Cortés cut down Coanacoch, the last to be hanged, after his brother began rallying his warriors. Coanacoch did not have long to enjoy his reprieve, as Ixtlilxóchitl wrote that he died a few days later. Tlacotzin, Cuauhtémoc's cihuacoatl, was appointed his successor as tlatoani. He died the next year before he could return to Tenochtitlan. Bones The modern-day town of Ixcateopan in the state of Guerrero is home to an ossuary purportedly containing Cuauhtémoc's remains. Archeologist Eulalia Guzmán, a "passionate indigenista", excavated the bones in 1949, which were discovered shortly after bones of Cortés, found in Mexico City, had been authenticated by the Instituto Nacional de Antropología e Historia (INAH). Initially, Mexican scholars congratulated Guzmán, but after a similar examination by scholars at INAH, their authenticity as Cuauhtemoc's was rejected, as the bones in the ossuary belonged to several different persons, several of them seemingly women. The finding caused a public uproar. A panel assembled by Guzmán gave support to the initial contention. The Secretariat of Public Education (SEP) had another panel examine the bones, which gave support to INAH's original finding, but did not report on the finding publicly. A scholarly study of the controversy was published in 2011 and argued that the available data suggests that the grave is an elaborate hoax prepared by a local of Ichcateopan as a way of generating publicity, and that subsequently supported by Mexican nationalists such as Guzman who wished to use the find for political purposes. Legacy Cuauhtemoc is the embodiment of indigenist nationalism in Mexico, being the only Aztec emperor who survived the conquest by the Spanish Empire (and their native allies). He is honored by a monument on the Paseo de la Reforma, his face has appeared on Mexican coins, banknotes, and he is celebrated in paintings, music, and popular culture.

In the Aztec campaign of the PC game Age of Empires II: The Conquerors, the player plays as Cuauhtémoc, despite the name Montezuma for the campaign itself, and Cuauhtémoc narrates the openings and closings to each scenario. In the next installment to the series, Age of Empires 3: The War Chiefs, Cuauhtémoc was the leader of Aztecs. In the 1996 Rage Against the Machine single People of the Sun, lyricist Zack De La Rocha rhymes "When the fifth sun sets get back reclaimed, The spirit of Cuauhtémoc alive and untamed". Cuauhtémoc, in the name Guatemoc, is portrayed sympathetically in the adventure novel Montezuma's Daughter, by H. Rider Haggard. First appearing in Chapter XIV, he becomes friends with the protagonist after they save each other's lives. His coronation, torture, and death are described in the novel.

take all possible values when averaging over many scattering events. The differential size of the cross section is the area element in the plane of the impact parameter, i.e. . The differential angular range of the scattered particle at angle is the solid angle element . The differential cross section is the quotient of these quantities, . It is a function of the scattering angle (and therefore also the impact parameter), plus other observables such as the momentum of the incoming particle. The differential cross section is always taken to be positive, even though larger impact parameters generally produce less deflection. In cylindrically symmetric situations (about the beam axis), the azimuthal angle is not changed by the scattering process, and the differential cross section can be written as . In situations where the scattering process is not azimuthally symmetric, such as when the beam or target particles possess magnetic moments oriented perpendicular to the beam axis, the differential cross section must also be expressed as a function of the azimuthal angle. For scattering of particles of incident flux off a stationary target consisting of many particles, the differential cross section at an angle is related to the flux of scattered particle detection in particles per unit time by Here is the finite angular size of the detector (SI unit: sr), is the number density of the target particles (SI units: m−3), and is the thickness of the stationary target (SI units: m). This formula assumes that the target is thin enough that each beam particle will interact with at most one target particle. The total cross section may be recovered by integrating the differential cross section over the full solid angle ( steradians): It is common to omit the “differential” qualifier when the type of cross section can be inferred from context. In this case, may be referred to as the integral cross section or total cross section. The latter term may be confusing in contexts where multiple events are involved, since “total” can also refer to the sum of cross sections over all events. The differential cross section is extremely useful quantity in many fields of physics, as measuring it can reveal a great amount of information about the internal structure of the target particles. For example, the differential cross section of Rutherford scattering provided strong evidence for the existence of the atomic nucleus. Instead of the solid angle, the momentum transfer may be used as the independent variable of differential cross sections. Differential cross sections in inelastic scattering contain resonance peaks that indicate the creation of metastable states and contain information about their energy and lifetime. Quantum scattering In the time-independent formalism of quantum scattering, the initial wave function (before scattering) is taken to be a plane wave with definite momentum : where and are the relative coordinates between the projectile and the target. The arrow indicates that this only describes the asymptotic behavior of the wave function when the projectile and target are too far apart for the interaction to have any effect. After scattering takes place it is expected that the wave function takes on the following asymptotic form: where is some function of the angular coordinates known as the scattering amplitude. This general form is valid for any short-ranged, energy-conserving interaction. It is not true for long-ranged interactions, so there are additional complications when dealing with electromagnetic interactions. The full wave function of the system behaves asymptotically as the sum The differential cross section is related to the scattering amplitude: This has the simple interpretation as the probability density for finding the scattered projectile at a given angle. A cross section is therefore a measure of the effective surface area seen by the impinging particles, and as such is expressed in units of area. The cross section of two particles (i.e. observed when the two particles are colliding with each other) is a measure of the interaction event between the two particles. The cross section is proportional to the probability that an interaction will occur; for example in a simple scattering experiment the number of particles scattered per unit of time (current of scattered particles ) depends only on the number of incident particles per unit of time (current of incident particles ), the characteristics of target (for example the number of particles per unit of surface ), and the type of interaction. For we have Relation to the S-matrix If the reduced masses and momenta of the colliding system are , and , before and after the collision respectively, the differential cross section is given by where the on-shell matrix is defined by in terms of the S-matrix. Here is the Dirac delta function. The computation of the S-matrix is the main goal of the scattering theory. Units Although the SI unit of total cross sections is m2, smaller units are usually used in practice. In nuclear and particle physics, the conventional unit is the barn b, where 1 b = 10−28 m2 = 100 fm2. Smaller prefixed units such as mb and μb are also widely used. Correspondingly, the differential cross section can be measured in units such as mb/sr. When the scattered radiation is visible light, it is conventional to measure the path length in centimetres. To avoid the need for conversion factors, the scattering cross section is expressed in cm2, and the number concentration in cm−3. The measurement of the scattering of visible light is known as nephelometry, and is effective for particles of 2–50 µm in diameter: as such, it is widely used in meteorology and in the measurement of atmospheric pollution. The scattering of X-rays can also be described in terms of scattering cross sections, in which case the square ångström is a convenient unit: 1 Å2 = 10−20 m2 = = 108 b. The sum of the scattering, photoelectric, and pair-production cross-sections (in barns) is charted as the "atomic attenuation coefficient" (narrow-beam), in barns. Scattering of light For light, as in other settings, the scattering cross section for particles is generally different from the geometrical cross section of the particle, and it depends upon the wavelength of light and the permittivity, shape, and size of the particle. The total amount of scattering in a sparse medium is proportional to the product of the scattering cross section and the number of particles present. In the interaction of light with particles, many processes occur, each with their own cross sections, including absorption, scattering, and photoluminescence. The sum of the absorption and scattering cross sections is sometimes referred to as the attenuation or extinction cross section. The total extinction cross section is related to the attenuation of the light intensity through the Beer–Lambert law, which says that attenuation is proportional to particle concentration: where is the attenuation at a given wavelength , is the particle concentration as a number density, and is the path length. The absorbance of the radiation is the logarithm (decadic or, more usually, natural) of the reciprocal of the transmittance : Combining the scattering and absorption cross sections in this manner is often necessitated by the inability to distinguish them experimentally, and much research effort has been put into developing models that allow them to be distinguished, the Kubelka-Munk theory being one of the most important in this area. Cross section and Mie theory Cross sections commonly calculated using Mie theory include efficiency coefficients for extinction , scattering , and Absorption cross sections. Those are normalized by the geometrical cross sections of the particle as The cross section is defined by where is the energy flow through the surrounding surface, and is the intensity of the incident wave. For plane wave the intensity is going to be , where is the
is used, with the target placed at the origin and the axis of this coordinate system aligned with the incident beam. The angle is the scattering angle, measured between the incident beam and the scattered beam, and the is the azimuthal angle. The impact parameter is the perpendicular offset of the trajectory of the incoming particle, and the outgoing particle emerges at an angle . For a given interaction (Coulombic, magnetic, gravitational, contact, etc.), the impact parameter and the scattering angle have a definite one-to-one functional dependence on each other. Generally the impact parameter can neither be controlled nor measured from event to event and is assumed to take all possible values when averaging over many scattering events. The differential size of the cross section is the area element in the plane of the impact parameter, i.e. . The differential angular range of the scattered particle at angle is the solid angle element . The differential cross section is the quotient of these quantities, . It is a function of the scattering angle (and therefore also the impact parameter), plus other observables such as the momentum of the incoming particle. The differential cross section is always taken to be positive, even though larger impact parameters generally produce less deflection. In cylindrically symmetric situations (about the beam axis), the azimuthal angle is not changed by the scattering process, and the differential cross section can be written as . In situations where the scattering process is not azimuthally symmetric, such as when the beam or target particles possess magnetic moments oriented perpendicular to the beam axis, the differential cross section must also be expressed as a function of the azimuthal angle. For scattering of particles of incident flux off a stationary target consisting of many particles, the differential cross section at an angle is related to the flux of scattered particle detection in particles per unit time by Here is the finite angular size of the detector (SI unit: sr), is the number density of the target particles (SI units: m−3), and is the thickness of the stationary target (SI units: m). This formula assumes that the target is thin enough that each beam particle will interact with at most one target particle. The total cross section may be recovered by integrating the differential cross section over the full solid angle ( steradians): It is common to omit the “differential” qualifier when the type of cross section can be inferred from context. In this case, may be referred to as the integral cross section or total cross section. The latter term may be confusing in contexts where multiple events are involved, since “total” can also refer to the sum of cross sections over all events. The differential cross section is extremely useful quantity in many fields of physics, as measuring it can reveal a great amount of information about the internal structure of the target particles. For example, the differential cross section of Rutherford scattering provided strong evidence for the existence of the atomic nucleus. Instead of the solid angle, the momentum transfer may be used as the independent variable of differential cross sections. Differential cross sections in inelastic scattering contain resonance peaks that indicate the creation of metastable states and contain information about their energy and lifetime. Quantum scattering In the time-independent formalism of quantum scattering, the initial wave function (before scattering) is taken to be a plane wave with definite momentum : where and are the relative coordinates between the projectile and the target. The arrow indicates that this only describes the asymptotic behavior of the wave function when the projectile and target are too far apart for the interaction to have any effect. After scattering takes place it is expected that the wave function takes on the following asymptotic form: where is some function of the angular coordinates known as the scattering amplitude. This general form is valid for any short-ranged, energy-conserving interaction. It is not true for long-ranged interactions, so there are additional complications when dealing with electromagnetic interactions. The full wave function of the system behaves asymptotically as the sum The differential cross section is related to the scattering amplitude: This has the simple interpretation as the probability density for finding the scattered projectile at a given angle. A cross section is therefore a measure of the effective surface area seen by the impinging particles, and as such is expressed in units of area. The cross section of two particles (i.e. observed when the two particles are colliding with each other) is a measure of the interaction event between the two particles. The cross section is proportional to the probability that an interaction will occur; for example in a simple scattering experiment the number of particles scattered per unit of time (current of scattered particles ) depends only on the number of incident particles per unit of time (current of incident particles ), the characteristics of target (for example the number of particles per unit of surface ), and the type of interaction. For we have Relation to the S-matrix If the reduced masses and momenta of the colliding system are , and , before and after the collision respectively, the differential cross section is given by where the on-shell matrix is defined by in terms of the S-matrix. Here is the Dirac delta function. The computation of the S-matrix is the main goal of the scattering theory. Units Although the SI unit of total cross sections is m2, smaller units are usually used in practice. In nuclear and particle physics, the conventional unit is the barn b, where 1 b = 10−28 m2 = 100 fm2. Smaller prefixed units such as mb and μb are also widely used. Correspondingly, the differential cross section can be measured in units such as mb/sr. When the scattered radiation is visible light, it is conventional to measure the path length in centimetres. To avoid the need for conversion factors, the scattering cross section is expressed in cm2, and the number concentration in cm−3. The measurement of the scattering of visible light is known as nephelometry, and is effective for particles of 2–50 µm in diameter: as such, it is widely used in meteorology and in the measurement of atmospheric pollution. The scattering of X-rays can also be described in terms of scattering cross sections, in which case the square ångström is a convenient unit: 1 Å2 = 10−20 m2 = = 108 b. The sum of the scattering, photoelectric, and pair-production cross-sections (in barns) is charted as the "atomic attenuation coefficient" (narrow-beam), in barns. Scattering of light For light, as in other settings, the scattering cross section for particles is generally different from the geometrical cross section of the particle, and it depends upon the wavelength of light and the permittivity, shape, and size of the particle. The total amount of scattering in a sparse medium is proportional to the product of the scattering cross section and the number of particles present. In the interaction of light with particles, many processes occur, each with their own cross sections, including absorption, scattering, and photoluminescence. The sum of the absorption and scattering cross sections is sometimes referred to as the attenuation or extinction cross section. The total extinction cross section is related to the attenuation of the light intensity through the Beer–Lambert law, which says that attenuation is proportional to particle concentration: where is the attenuation at a given wavelength , is the particle concentration as a number density, and is the path length. The absorbance of the radiation is the logarithm (decadic or, more usually, natural) of the reciprocal of the transmittance : Combining the scattering and absorption cross sections in this manner is often necessitated by the inability to distinguish them experimentally, and much research effort has been put into developing models that allow them to be distinguished, the Kubelka-Munk theory being one of the most important in this area. Cross section and Mie theory Cross sections commonly calculated using Mie theory include efficiency coefficients for extinction , scattering , and Absorption cross sections. Those are normalized by the geometrical cross sections of the particle as The
his crucifixion, rescuing the righteous souls that had been cut off from heaven due to the taint of original sin. The story of the harrowing was popular during the Middle Ages. An Old English poem called "The Harrowing of Hell" describes Christ breaking into Hell and rescuing the Old Testament patriarchs. (The Harrowing is not the only explanation that Christians have put forth for the fate of the righteous who died before Christ accomplished the atonement) In modern literature, atonement continues to be theme. In the first of C. S. Lewis's Narnia novels, The Lion, the Witch and the Wardrobe, a boy named Edmund is condemned to death by a White Witch, and the magical lion-king Aslan offers to die in Edmund's place, thereby saving him. Aslan's life is sacrificed on an altar, but returns to life again. Aslan's self-sacrifice for Edmund is often interpreted as an allegory for the story of Christ's sacrifice for humanity; although Lewis denied that the novel is a mere allegory. Eschatological myths Christian eschatological myths include stories of the afterlife: the narratives of Jesus Christ rising from the dead and now acting as a saviour of all generations of Christians, and stories of heaven and hell. Eschatological myths would also include the prophesies of end of the world and a new millennium in the Book of Revelation, and the story that Jesus will return to earth some day. The major features of Christian eschatological mythology include afterlife beliefs, the Second Coming, the resurrection of the dead, and the final judgment. Immediate afterlife (heaven and hell) Most Christian denominations hold some belief in an immediate afterlife when people die. Christian scripture gives a few descriptions of an immediate afterlife and a heaven and hell; however, for the most part, both New and Old Testaments focus much more on the myth of a final bodily resurrection than any beliefs about a purely spiritual afterlife away from the body. Much of the Old Testament does not express a belief in a personal afterlife of reward or punishment:"All the dead go down to Sheol, and there they lie in sleep together–whether good or evil, rich or poor, slave or free (Job 3:11-19). It is described as a region "dark and deep," "the Pit," and "the land of forgetfulness," cut off from both God and human life above (Pss. 6:5; 88:3-12). Though in some texts Yahweh's power can reach down to Sheol (Ps. 139:8), the dominant idea is that the dead are abandoned forever. This idea of Sheol is negative in contrast to the world of life and light above, but there is no idea of judgment or of reward and punishment." Later Old Testament writings, particularly the works of the Hebrew prophets, describe a final resurrection of the dead, often accompanied by spiritual rewards and punishments:"Many who sleep in the dust of the earth shall awake. Some shall live forever; others shall be in everlasting contempt. But the wise shall shine brightly like the splendor of the firmament, and those who lead the many to justice shall be like the stars forever" (Daniel 12:2). However, even here, the emphasis is not on an immediate afterlife in heaven or hell, but rather on a future bodily resurrection. The New Testament also devotes little attention to an immediate afterlife. Its primary focus is the resurrection of the dead. Some New Testament passages seem to mention the (non-resurrected) dead experiencing some sort of afterlife (for example, the parable of Lazarus and Dives); yet the New Testament includes only a few myths about heaven and hell. Specifically, heaven is a place of peaceful residence, where Jesus goes to "prepare a home" or room for his disciples (John 14:2). Drawing on scriptural imagery (John 10:7, John 10:11-14), many Christian narratives of heaven include a nice green pasture land and a meeting with a benevolent God. Some of the earliest Christian art depicts heaven as a green pasture where people are sheep led by Jesus as "the good shepherd" as in interpretation of heaven. As the doctrines of heaven and hell and (Catholic) purgatory developed, non-canonical Christian literature began to develop an elaborate mythology about these locations. Dante's three-part Divine Comedy is a prime example of such afterlife mythology, describing Hell (in Inferno), Purgatory (in Purgatorio), and Heaven (in Paradiso). Myths of hell differ quite widely according to the denomination. Second Coming The Second Coming of Christ holds a central place in Christian mythology. The Second Coming is the return of Christ to earth during the period of transformation preceding the end of this world and the establishment of the Kingdom of Heaven on earth. According to Matthew's gospel, when Jesus is on trial before the Roman and Jewish authorities, he claims, "In the future you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven." The legend of the Wandering Jew concerns a Jew who taunted Jesus on the way to the Crucifixion and was then cursed to walk the earth until the Second Coming. Resurrection and final judgment Christian mythology incorporates the Old Testament's prophecies of a future resurrection of the dead. Like the Hebrew prophet Daniel (e.g., Daniel 12:2), the Christian Book of Revelation (among other New Testament scriptures) describes the resurrection: "The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them; and they were judged, every one of them according to their deeds." The righteous and/or faithful enjoy bliss in the earthly Kingdom of Heaven, but the evil and/or non-Christian are "cast into the lake of fire". The Kingdom of Heaven on earth Christian eschatological myths feature a total world renovation after the final judgment. According to the Book of Revelation, God "will wipe every tear from their eyes, and there will be no more death or mourning, wailing or pain, for the old order has passed away". According to Old and New Testament passages, a time of perfect peace and happiness is coming: "They will beat their swords into plowshares and their spears into pruning hooks. One nation will not raise the sword against another; nor will they train for war again." Certain scriptural passages even suggest that God will abolish the current natural laws in favor of immortality and total peace: "Then the wolf will be a guest of the lamb, and the leopard will lie down with the kid. The calf and the young lion will browse together, with a little child to guide them. [...] There will be no harm or ruin on all my holy mountain, for the earth will be filled with knowledge of the Lord as water fills the sea." "On this mountain, [God] will destroy the veil that veils all peoples, the web that is woven over all nations: he will destroy Death forever." "The trumpet will sound, and the dead will be raised imperishable, and we will be changed." "Night will be no more, nor will they need light from lamp or sun, for the Lord God shall give them light, and they shall reign forever and ever." Millennialism and amillennialism When Christianity was a new and persecuted religion, many Christians believed the end times were imminent. Scholars debate whether Jesus was an apocalyptic preacher; however, his early followers, "the group of Jews who accepted him as messiah in the years immediately after his death, understood him in primarily apocalyptic terms". Prevalent in the early church and especially during periods of persecution, this Christian belief in an imminent end is called "millennialism". (It takes its name from the thousand-year ("millennial") reign of Christ that, according to the Book of Revelation, will precede the final world renovation; similar beliefs in a coming paradise are found in other religions, and these phenomena are often also called "millennialism") Millennialism comforted Christians during times of persecution, for it predicted an imminent deliverance from suffering. From the perspective of millennialism, human action has little significance: millennialism is comforting precisely because it predicts that happiness is coming no matter what humans do: "The seeming triumph of Evil made up the apocalyptic syndrome which was to precede Christ's return and the millennium." However, as time went on, millennialism lost its appeal. Christ had not returned immediately, as earlier Christians had predicted. Moreover, many Christians no longer needed the comfort that millennialism provided, for they were no longer persecuted: "With the triumph of the Church, the Kingdom of Heaven was already present on earth, and in a certain sense the old world had already been destroyed." (Millennialism has revived during periods of historical stress, and is currently popular among Evangelical Christians) In the Roman Church's condemnation of millennialism, Eliade sees "the first manifestation of the doctrine of [human] progress" in Christianity. According to the amillennial view, Christ will indeed come again, ushering in a perfect Kingdom of Heaven on earth, but "the Kingdom of God is [already] present in the world today through the presence of the heavenly reign of Christ, the Bible, the Holy Spirit and Christianity". Amillennialists do not feel "the eschatological tension" that persecution inspires; therefore, they interpret their eschatological myths either figuratively or as descriptions of far-off events rather than imminent ones. Thus, after taking the amillennial position, the Church not only waited for God to renovate the world (as millennialists had) but also believed itself to be improving the world through human action. Witches In the early modern period, distinguished Christian theologians developed elaborated witch mythologies which contributed to the intensification of witch hunts. Major works in Christian demonology, such as Malleus Maleficarum, were dedicated to the implementation of Exodus 22:18 of the Old Testament: "You shall not permit a sorceress to live." The concept of witches' sabbath was well articulated by the 17th century. Theologian Martin Delrio was one of the first to provide a vivid description in his influential Disquisitiones magicae: There, on most occasions, once a foul, disgusting fire has been lit, an evil spirit sits on a throne as president of the assembly. His appearance is terrifying, almost always that of a male goat or a dog. The witches come forward to worship him in different ways. Sometimes they supplicate him on bended knee; sometimes they stand with their back turned to him. They offer candles made of pitch or a child's umbilical cord, and kiss him on the anal orifice as a sign of homage. Sometimes they imitate the sacrifice of the Mass (the greatest of all their crimes), as well as purifying with water and similar Catholic ceremonies. After the feast, each evil spirit takes by the hand the disciple of whom he has charge, and so that they may do everything with the most absurd kind of ritual, each person bends over backwards, joins hands in a circle, and tosses his head as frenzied fanatics do. Then they begin to dance. They sing very obscene songs in his [Satan's] honour. They behave ridiculously in every way, and in every way contrary to accepted custom. Then their demon-lovers copulate with them in the most repulsive fashion. Legendary creatures Numerous legendary creatures are attested in Christian mythology. These include the Behemoth, Leviathan, Angels, Demons, Nephilim, Re'em, Ziz and dragons. Attitudes toward time According to Mircea Eliade, many traditional societies have a cyclic sense of time, periodically reenacting mythical events. Through this reenactment, these societies achieve an "eternal return" to the mythical age. According to Eliade, Christianity retains a sense of cyclical time, through the ritual commemoration of Christ's life and the imitation of Christ's actions; Eliade calls this sense of cyclical time a "mythical aspect" of Christianity. However, Judeo-Christian thought also makes an "innovation of the first importance", Eliade says, because it embraces the notion of linear, historical time; in Christianity, "time is no longer [only] the circular Time of the Eternal Return; it has become linear and irreversible Time". Summarizing Eliade's statements on this subject, Eric Rust writes, "A new religious structure became available. In the Judaeo-Christian religions—Judaism, Christianity, Islam—history is taken seriously, and linear time is accepted. [...] The Christian myth gives such time a beginning in creation, a center in the Christ-event, and an end in the final consummation." In contrast, the myths of many traditional cultures present a cyclic or static view of time. In these cultures, all the "[important] history is limited to a few events that took place in the mythical times". In other words, these cultures place events into two categories, the mythical age and the present, between which there is no continuity. Everything in the present is seen as a direct result of the mythical age: "Just as modern man considers himself to be constituted by [all of] History, the man of the archaic societies declares that he is the result of [only] a certain number of mythical events." Because of this view, Eliade argues, members of many traditional societies see their lives as a constant repetition of mythical events, an "eternal return" to the mythical age: "In imitating the exemplary acts of a god or of a mythical hero, or simply by recounting their adventures, the man of an archaic society detaches himself from profane time and magically re-enters the Great Time, the sacred time." According to Eliade, Christianity shares in this cyclic sense of time to an extent. "By the very fact that it is a religion", he argues, Christianity retains at least one "mythical aspect" — the repetition of mythical events through ritual. Eliade gives a typical church service as an example:"Just as a church constitutes a break in plane in the profane space of a modern city, [so] the service celebrated inside [the church] marks a break in profane temporal duration. It is no longer today's historical time that is present—the time that is experienced, for example, in the adjacent streets—but the time in which the historical existence of Jesus Christ occurred, the time sanctified by his preaching, by his passion, death, and resurrection." Heinrich Zimmer also notes Christianity's emphasis on linear time; he attributes this emphasis specifically to the influence of Augustine of Hippo's theory of history. Zimmer does not explicitly describe the cyclical conception of time as itself "mythical" per se, although he notes that this conception "underl[ies] Hindu mythology". Neil Forsyth writes that "what distinguishes both Jewish and Christian religious systems [...] is that they elevate to the sacred status of myth narratives that are situated in historical time". Legacy Concepts of progress According to Carl Mitcham, "the Christian mythology of progress toward transcendent salvation" created the conditions for modern ideas of scientific and technological progress. Hayden White describes "the myth of Progress" as the "secular, Enlightenment counterpart" of "Christian myth". Reinhold Niebuhr described the modern idea of ethical and scientific progress as "really a rationalized version of the Christian myth of salvation". According to Irwin, from the perspective of the Hebrew Bible (Old Testament), "history is a tale of progress". Christianity inherited the Hebrew sense of history through the Old Testament. Thus, although most Christians believe that human nature is inherently "fallen" (see original sin) and cannot become perfected without divine grace, they do believe that the world can and will change for the better, either through human and divine action or through divine action alone. Political and philosophical ideas According to Mircea Eliade, the medieval "Gioacchinian myth [...] of universal renovation in a more or less imminent future" has influenced a number of modern theories of history, such as those of Lessing (who explicitly compares his views to those of medieval "enthusiasts"), Fichte, Hegel, and Schelling; and has also influenced a number of Russian writers. Calling Marxism "a truly messianic Judaeo-Christian ideology", Eliade writes that Marxism "takes up and carries on one of the great eschatological myths of the Middle Eastern and Mediterranean world, namely: the redemptive part to be played by the Just (the 'elect', the 'anointed', the 'innocent', the 'missioners', in our own days the proletariat), whose sufferings are invoked to change the ontological status of the world". In his article "The Christian Mythology of Socialism", Will Herberg argues that socialism inherits the structure of its ideology from the influence of Christian mythology upon western thought. In The Oxford Companion to World Mythology, David Leeming claims that Judeo-Christian messianic ideas have influenced 20th-century totalitarian systems, citing the state ideology of the Soviet Union as an example. According to Hugh S. Pyper, the biblical "founding myths of the Exodus and the exile, read as stories in which a nation is forged by maintaining its ideological and racial purity in the face of an oppressive great power", entered "the rhetoric of nationalism throughout European history", especially in Protestant countries and smaller nations. Christmas stories in popular culture Christmas stories have become prevalent in Western literature and culture. The Bible Old Testament Mythic patterns such as the primordial struggle between good and evil appear in passages throughout the Hebrew Bible, including passages that describe historical events. A distinctive characteristic of the Hebrew Bible is the reinterpretation of myth on the basis of history, as in the Book of Daniel, a record of the experience of the Jews of the Second Temple period under foreign rule, presented as a prophecy of future events and expressed in terms of "mythic structures" with "the Hellenistic kingdom figured as a terrifying monster that cannot but recall [the Near Eastern pagan myth of] the dragon of chaos". Mircea Eliade argues that the imagery used in some parts of the Hebrew Bible reflects a "transfiguration of history into myth". For example, Eliade says, the portrayal of Nebuchadnezzar as a dragon in Jeremiah 51:34 is a case in which the Hebrews "interpreted contemporary events by means of the very ancient cosmogonico-heroic myth" of a battle between a hero and a dragon. According to scholars including Neil Forsyth and John L. McKenzie, the Old Testament incorporates stories, or fragments of stories, from extra-biblical mythology. According to the New American Bible, a Catholic Bible translation produced by the Confraternity of Christian Doctrine, the story of the Nephilim in Genesis 6:1-4 "is apparently a fragment of an old legend that had borrowed much from ancient mythology", and the "sons of God" mentioned in that passage are "celestial beings of mythology". The New American Bible also says that Psalm 93 alludes to "an ancient myth" in which God battles a personified Sea. Some scholars have identified the biblical creature Leviathan as a monster from Canaanite mythology. According to Howard Schwartz, "the myth of the fall of Lucifer" existed in fragmentary form in Isaiah 14:12 and other ancient Jewish literature; Schwartz claims that the myth originated from "the ancient Canaanite myth of Athtar, who attempted to rule the throne of Ba'al, but was forced to descend and rule the underworld instead". Some scholars have argued that the calm, orderly, monotheistic creation story in Genesis 1 can be interpreted as a reaction against the creation myths of other Near Eastern cultures. In connection with this interpretation, David and Margaret Leeming describe Genesis 1 as a "demythologized myth", and John L. McKenzie asserts that the writer of Genesis 1 has "excised the mythical elements" from his creation story. Perhaps the most famous topic in the Bible that could possibly be connected with mythical origins is the topic of Heaven (or the sky) as the place where God (or angels, or the saints) resides, with stories such as the ascension of Elijah (who disappeared in the sky), war of man with an angel, flying angels. Even in the New Testament Paul the Apostle is said to have visited the third heaven, and Jesus was portrayed in several books as
Knights Templar and the Priory of Sion. Medieval Christian stories about angels and guardian angels. Non-canonical elaborations or amendments to Biblical tales, such as the tales of Salomé, the Three Wise Men, or St. Dismas. Connections to other belief systems Jewish mythology Cosmogony The 7-day creation week narrative (Genesis 1-2:3) The Eden narrative (Genesis 2:4-3:24) Origins The Fall of Man: Although the Book of Genesis does not mention original sin, many Christians interpret the Fall as the origin of original sin. Noah's Ark The Tower of Babel: the origin and division of nations and languages The life of Abraham The Exodus of the Hebrews from Egypt The Hebrews' conquest of the Promised Land The period of the Hebrew prophets. One example is the apocryphal part of the Book of Daniel (14:1-30; excluded from the Hebrew and Protestant canon) that tells the story of Bel and the dragon. Zoroastrianism Some scholars believe that many elements of Christian mythology, particularly its linear portrayal of time, originated with the Persian religion of Zoroastrianism. Mary Boyce, an authority on Zoroastrianism, writes: Mircea Eliade believes the Hebrews had a sense of linear time before Zoroastrianism influenced them. However, he argues, "a number of other [Jewish] religious ideas were discovered, revalorized, of systematized in Iran". These ideas include a dualism between good and evil, belief in a future savior and resurrection, and "an optimistic eschatology, proclaiming the final triumph of Good". The Zoroastrian concepts of Ahriman, Amesha Spentas, Yazatas, and Daevas probably gave rise to the Christian understanding of Satan, archangels, angels, and demons. Other connections In Buddhist mythology, the demon Mara tries to distract the historical Buddha, Siddhartha Gautama, before he can reach enlightenment. Huston Smith, a professor of philosophy and a writer on comparative religion, notes the similarity between Mara's temptation of the Buddha before his ministry and Satan's temptation of Christ before his ministry. In the Book of Revelation, the author sees a vision of a pregnant woman in the sky being pursued by a huge red dragon. The dragon tries to devour her child when she gives birth, but the child is "caught up to God and his throne". This appears to be an allegory for the triumph of Christianity: the child presumably represents Christ; the woman may represent God's people of the Old and New Testaments (who produced Christ); and the Dragon symbolizes Satan, who opposes Christ. According to Catholic scholars, the images used in this allegory may have been inspired by pagan mythology: Mythical themes and types Academic studies of mythology often define mythology as deeply valued stories that explain a society's existence and world order: those narratives of a society's creation, the society's origins and foundations, their god(s), their original heroes, mankind's connection to the "divine", and their narratives of eschatology (what happens in the "after-life"). This is a very general outline of some of the basic sacred stories with those themes. Cosmogonic myths The Christian texts use the same creation myth as Jewish mythology as written in the Old Testament. According to the Book of Genesis, the world was created out of a darkness and water in seven days. (Unlike a Jew, a Christian might include the miracle of Jesus' birth as a sort of second cosmogonic event) Canonical Christian scripture incorporates the two Hebrew cosmogonic myths found in Genesis 1-2:2 and Genesis 2: Genesis 1–2:3 In the first text on the creation (Genesis 1-2:3), the Creator is called Elohim (translated "God"). He creates the universe over a six-day period, creating a new feature each day: first he creates day and night; then he creates the firmament to separate the "waters above" from the "waters below"; then he separates the dry land from the water; then he creates plants on the land; then he places the Sun, Moon, and stars in the sky; then he creates swimming and flying animals; then he creates land animals; and finally he creates man and woman together, "in his own image". On the seventh day, God rests, providing the rationale for the custom of resting on Sabbath. Genesis 2:4–3:24 The second creation myth in Genesis differs from the first in a number of important elements. Here the Creator is called Yahweh elohim (commonly translated "Lord God", although Yahweh is in fact the personal name of the God of Israel and does not mean Lord). This myth begins with the words, "When the LORD God made the earth and the heavens, and no shrub of the field was yet in the earth, and no plant of the field had yet sprouted, for the LORD God had not sent rain upon the earth ..." (Genesis 2:4-5 NASB). It then proceeds to describe Yahweh creating a man called Adam out of dust. Yahweh creates the Garden of Eden as a home for Adam, and tells Adam not to eat the fruit of the Tree of Knowledge of Good and Evil in the center of the Garden (next to the Tree of Life). Yahweh also creates animals, and shows them to man, who names them. Yahweh sees that there is no suitable companion for the man among the beasts, and he subsequently puts Adam to sleep and takes out one of Adam's ribs, creating from it a woman whom Adam names Eve. A serpent tempts Eve to eat from the Tree of Knowledge of Good and Evil, and she succumbs, offering the fruit to Adam as well. As a punishment, Yahweh banishes the couple from the Garden and "placed on the east side of the Garden of Eden the cherubim with a fiery revolving sword to guard the way to the Tree of Life". The Lord says he must banish humans from the Garden because they have become like him, knowing good and evil (because of eating the forbidden fruit), and now only immortality (which they could get by eating from the Tree of Life) stands between them and godhood: "The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever" (Genesis 3:22). Although the text of Genesis does not identify the tempting serpent with Satan, Christian tradition equates the two. This tradition has made its way into non-canonical Christian "myths" such as John Milton's Paradise Lost. Ascending the mountain According to Lorena Laura Stookey, many myths feature sacred mountains as "the sites of revelations": "In myth, the ascent of the holy mountain is a spiritual journey, promising purification, insight, wisdom, or knowledge of the sacred". As examples of this theme, Stookey includes the revelation of the Ten Commandments on Mount Sinai, Christ's ascent of a mountain to deliver his Sermon on the Mount, and Christ's ascension into Heaven from the Mount of Olives. Axis mundi Many mythologies involve a "world center", which is often the sacred place of creation; this center often takes the form of a tree, mountain, or other upright object, which serves as an axis mundi or axle of the world. A number of scholars have connected the Christian story of the crucifixion at Golgotha with this theme of a cosmic center. In his Creation Myths of the World, David Leeming argues that, in the Christian story of the crucifixion, the cross serves as "the axis mundi, the center of a new creation". According to a tradition preserved in Eastern Christian folklore, Golgotha was the summit of the cosmic mountain at the center of the world and the location where Adam had been both created and buried. According to this tradition, when Christ is crucified, his blood falls on Adam's skull, buried at the foot of the cross, and redeems him. George Every discusses the connection between the cosmic center and Golgotha in his book Christian Mythology, noting that the image of Adam's skull beneath the cross appears in many medieval representations of the crucifixion. In Creation Myths of the World, Leeming suggests that the Garden of Eden may also be considered a world center. Combat myth Many Near Eastern religions include a story about a battle between a divine being and a dragon or other monster representing chaos—a theme found, for example, in the Enuma Elish. A number of scholars call this story the "combat myth". A number of scholars have argued that the ancient Israelites incorporated the combat myth into their religious imagery, such as the figures of Leviathan and Rahab, the Song of the Sea, Isaiah 51:9-10's description of God's deliverance of his people from Babylon, and the portrayals of enemies such as Pharaoh and Nebuchadnezzar. The idea of Satan as God's opponent may have developed under the influence of the combat myth. Scholars have also suggested that the Book of Revelation uses combat myth imagery in its descriptions of cosmic conflict. Descent to the underworld According to David Leeming, writing in The Oxford Companion to World Mythology, the harrowing of hell is an example of the motif of the hero's descent to the underworld, which is common in many mythologies. According to Christian tradition, Christ descended to hell after his death in order to free the souls there; this event is known as the Harrowing of Hell. This story is narrated in the Gospel of Nicodemus and may be the meaning behind 1 Peter 3:18-22. Dying god Many myths, particularly from the Near East, feature a god who dies and is resurrected; this figure is sometimes called the "dying god". An important study of this figure is James George Frazer's The Golden Bough, which traces the dying god theme through a large number of myths. The dying god is often associated with fertility. A number of scholars, including Frazer, have suggested that the Christ story is an example of the "dying god" theme. In the article "Dying god" in The Oxford Companion to World Mythology, David Leeming notes that Christ can be seen as bringing fertility, though of a spiritual as opposed to physical kind. In his 2006 homily for Corpus Christi, Pope Benedict XVI noted the similarity between the Christian story of the resurrection and pagan myths of dead and resurrected gods: "In these myths, the soul of the human person, in a certain way, reached out toward that God made man, who, humiliated unto death on a cross, in this way opened the door of life to all of us." Flood myths Many cultures have myths about a flood that cleanses the world in preparation for rebirth. Such stories appear on every inhabited continent on earth. An example is the biblical story of Noah. In The Oxford Companion to World Mythology, David Leeming notes that, in the Bible story, as in other flood myths, the flood marks a new beginning and a second chance for creation and humanity. Founding myths According to Sandra Frankiel, the records of "Jesus' life and death, his acts and words" provide the "founding myths" of Christianity. Frankiel claims that these founding myths are "structurally equivalent" to the creation myths in other religions, because they are "the pivot around which the religion turns to and which it returns", establishing the "meaning" of the religion and the "essential Christian practices and attitudes". Tom Cain uses the expression "founding myths" more broadly, to encompass such stories as those of the War in Heaven and the fall of man; according to Cain, "the disastrous consequences of disobedience" is a pervasive theme in Christian founding myths. Christian mythology of their society's founding would start with Jesus and his many teachings, and include the stories of Christian disciples starting the Christian Church and congregations in the 1st century. This might be considered the stories in the four canonical gospels and the Acts of the Apostles. The heroes of the first Christian society would start with Jesus and those chosen by Jesus, the twelve apostles including Peter, John, James, as well as Paul and Mary (mother of Jesus). Hero myths In his influential 1909 work The Myth of the Birth of the Hero, Otto Rank argued that the births of many mythical heroes follow a common pattern. Rank includes the story of Christ's birth as a representative example of this pattern. According to Mircea Eliade, one pervasive mythical theme associates heroes with the slaying of dragons, a theme which Eliade traces back to "the very ancient cosmogonico-heroic myth" of a battle between a divine hero and a dragon. He cites the Christian legend of Saint George as an example of this theme. An example from the Late Middle Ages comes from Dieudonné de Gozon, third Grand Master of the Knights of Rhodes, famous for slaying the dragon of Malpasso. Eliade writes: "Legend, as was natural, bestowed upon him the attributes of St. George, famed for his victorious fight with the monster. [...] In other words, by the simple fact that he was regarded as a hero, de Gozon was identified with a category, an archetype, which [...] equipped him with a mythical biography from which it was impossible to omit combat with a reptilian monster." In the Oxford Companion to World Mythology David Leeming lists Moses, Jesus, and King Arthur as examples of the heroic monomyth, calling the Christ story "a particularly complete example of the heroic monomyth". Leeming regards resurrection as a common part of the heroic monomyth, in which the resurrected heroes often become sources of "material or spiritual food for their people"; in this connection, Leeming notes that Christians regard Jesus as the "bread of life". In terms of values, Leeming contrasts "the myth of Jesus" with the myths of other "Christian heroes such as St. George, Roland, el Cid, and even King Arthur"; the later hero myths, Leeming argues, reflect the survival of pre-Christian heroic values—"values of military dominance and cultural differentiation and hegemony"—more than the values expressed in the Christ story. Paradise Many religious and mythological systems contain myths about a paradise. Many of these myths involve the loss of a paradise that existed at the beginning of the world. Some scholars have seen in the story of the Garden of Eden an instance of this general motif. Sacrifice Sacrifice is an element in many religious traditions and often represented in myths. In The Oxford Companion to World Mythology, David Leeming lists the story of Abraham and Isaac and the story of Christ's death as examples of this theme. Wendy Doniger describes the gospel accounts as a "meta-myth" in which Jesus realizes that he is part of a "new myth [...] of a man who is sacrificed in hate" but "sees the inner myth, the old myth of origins and acceptance, the myth of a god who sacrifices himself in love". Eucharist Related to the doctrine of transsubstantiation, the Christian practice of eating the flesh and blood of Jesus Christ during the Eucharist is an instance of theophagy. Transference of evil The theological concept of Jesus being born to atone for original sin is central to the Christian narrative. According to Christian theology, by Adam disobeying God in the Garden of Eden, humanity acquired an ingrained flaw that keeps humans in a state of moral imperfection, generally called "original sin". According to Paul the Apostle, Adam's sin brought sin and death to all humanity: "Through one man, sin entered the world, and through sin, death" (Romans 5:12). According to the orthodox Christian view, Jesus saved humanity from final death and damnation by dying for them. Most Christians believe that Christ's sacrifice supernaturally reversed death's power over humanity, proved when he was resurrected, and abolished the power of sin on humanity. According to Paul, "if the many died by the trespass of the one man, how much more did God's grace and the gift that came by the grace of the one man, Jesus Christ, overflow to the many" (Romans 5:15). For many Christians, atonement doctrine leads naturally into the eschatological narratives of Christian people rising from the dead and living again, or immediately entering heaven to join Jesus. Atonement in canonical scripture Paul's theological writings lay out the basic framework of the atonement doctrine in the New Testament. However, Paul's letters contain relatively little mythology (narrative). The majority of narratives in the New Testament are in the Gospels and the Book of Revelation. Although the Gospel stories do not lay out the atonement doctrine as fully as does Paul, they do have the story of the Last Supper, crucifixion, death and resurrection. Atonement is also suggested in the parables of Jesus in his final days. According to Matthew's gospel, at the Last Supper, Jesus calls his blood "the blood of the new covenant, which will be poured out for the forgiveness of many" (Matthew 26:28). John's gospel is especially rich in atonement parables and promises: Jesus speaks of himself as "the living bread that came down from heaven"; "and the bread that I shall give is My flesh, which I shall give for the life of the world" (John 6:51); "Truly, truly, I say to you, unless a grain of wheat falls to the ground and dies, it remains alone; but if it dies, it bears much fruit" (John 12:24). Atonement in non-canonical literature The sacrifice and atonement narrative appears explicitly in many non-canonical writings as well. For instance, in Book 3 of Milton's Paradise Lost, the Son of God offers to become a man and die, thereby paying mankind's debt to God the Father. The Harrowing of Hell is a non-canonical myth extrapolated from the atonement doctrine. According to this story, Christ descended into the land of the dead after his crucifixion, rescuing the righteous souls that had been cut off from heaven due to the taint of original sin. The story of the harrowing was popular during the Middle Ages. An Old English poem called "The Harrowing of Hell" describes Christ breaking into Hell and rescuing the Old Testament patriarchs. (The Harrowing is not the only explanation that Christians have put forth for the fate of the righteous who died before Christ accomplished the atonement) In modern literature, atonement continues to be theme. In the first of C. S. Lewis's Narnia novels, The Lion, the Witch and the Wardrobe, a boy named Edmund is condemned to death by a White Witch, and the magical lion-king Aslan offers to die in Edmund's place, thereby saving him. Aslan's life is sacrificed on an altar, but returns to life again. Aslan's self-sacrifice for Edmund is often interpreted as an allegory for the story of Christ's sacrifice for humanity; although Lewis denied that the novel is a mere allegory. Eschatological myths Christian eschatological myths include stories of the afterlife: the narratives of Jesus Christ rising from the dead and now acting as a saviour of all generations of Christians, and stories of heaven and hell. Eschatological myths would also include the prophesies of end of the world and a new millennium in the Book of Revelation, and the story that Jesus will return to earth some day. The major features of Christian eschatological mythology include afterlife beliefs, the Second Coming, the resurrection of the dead, and the final judgment. Immediate afterlife (heaven and hell) Most Christian denominations hold some belief in an immediate afterlife when people die. Christian scripture gives a few descriptions of an immediate afterlife and a heaven and hell; however, for the most part, both New and Old Testaments focus much more on the myth of a final bodily resurrection than any beliefs about a purely spiritual afterlife away from the body. Much of the Old Testament does not express a belief in a personal afterlife of reward or punishment:"All the dead go down to Sheol, and there they lie in sleep together–whether good or evil, rich or poor, slave or free (Job 3:11-19). It is described as a region "dark and deep," "the Pit," and "the land of forgetfulness," cut off from both God and human life above (Pss. 6:5; 88:3-12). Though in some texts Yahweh's power can reach down to Sheol (Ps. 139:8), the dominant idea is that the dead are abandoned forever. This idea of Sheol is negative in contrast to the world of life and light above, but there is no idea of judgment or of reward and punishment." Later Old Testament writings, particularly the works of the Hebrew prophets, describe a final resurrection of the dead, often accompanied by spiritual rewards and punishments:"Many who sleep in the dust of the earth shall awake. Some shall live forever; others shall be in everlasting contempt. But the wise shall shine brightly like the splendor of the firmament, and those who lead the many to justice shall be like the stars forever" (Daniel 12:2). However, even here, the emphasis is not on an immediate afterlife in heaven or hell, but rather on a future bodily resurrection. The New Testament also devotes little attention to an immediate afterlife. Its primary focus is the resurrection of the dead. Some New Testament passages seem to mention the (non-resurrected) dead experiencing some sort of afterlife (for example, the parable of Lazarus and Dives); yet the New Testament includes only a few myths about heaven and hell. Specifically, heaven is a place of peaceful residence, where Jesus goes to "prepare a home" or room for his disciples (John 14:2). Drawing on scriptural imagery (John 10:7, John 10:11-14), many Christian narratives of heaven include a nice green pasture land and a meeting with a benevolent God. Some of the earliest Christian art depicts heaven as a green pasture where people are sheep led by Jesus as "the good shepherd" as in interpretation of heaven. As the doctrines of heaven and hell and (Catholic) purgatory developed, non-canonical Christian literature began to develop an elaborate mythology about these locations. Dante's three-part Divine Comedy is a prime example of such afterlife mythology, describing Hell (in Inferno), Purgatory (in Purgatorio), and Heaven (in Paradiso). Myths of hell differ quite widely according to the denomination. Second Coming The Second Coming of Christ holds a central place in Christian mythology. The Second Coming is the return of Christ to earth during the period of transformation preceding the end of this world and the establishment of the Kingdom of Heaven on earth. According to Matthew's gospel, when Jesus is on trial before the Roman and Jewish authorities, he claims, "In the future you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven." The legend of the Wandering Jew concerns a Jew who taunted Jesus on the way to the Crucifixion and was then cursed to walk the earth until the Second Coming. Resurrection and final judgment Christian mythology incorporates the Old Testament's prophecies of a future resurrection of the dead. Like the Hebrew prophet Daniel (e.g., Daniel 12:2), the Christian Book of Revelation (among other New Testament scriptures) describes the resurrection: "The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them; and they were judged, every one of them according to their deeds." The righteous and/or faithful enjoy bliss in the earthly Kingdom of Heaven, but the evil and/or non-Christian are "cast into the lake of fire". The Kingdom of Heaven on earth Christian eschatological myths feature a total world renovation after the final judgment. According to the Book of Revelation, God

these were all restrictive in design, often with the intention of preventing corporations from gaining too much wealth and power. New Jersey was the first state to adopt an "enabling" corporate law, with the goal of attracting more business to the state, in 1896. In 1899, Delaware followed New Jersey's lead with the enactment of an enabling corporate statute, but Delaware only became the leading corporate state after the enabling provisions of the 1896 New Jersey corporate law were repealed in 1913. The end of the 19th century saw the emergence of holding companies and corporate mergers creating larger corporations with dispersed shareholders. Countries began enacting antitrust laws to prevent anti-competitive practices and corporations were granted more legal rights and protections. The 20th century saw a proliferation of laws allowing for the creation of corporations by registration across the world, which helped to drive economic booms in many countries before and after World War I. Another major post World War I shift was toward the development of conglomerates, in which large corporations purchased smaller corporations to expand their industrial base. Starting in the 1980s, many countries with large state-owned corporations moved toward privatization, the selling of publicly owned (or 'nationalised') services and enterprises to corporations. Deregulation (reducing the regulation of corporate activity) often accompanied privatization as part of a laissez-faire policy. Ownership and control A corporation is, at least in theory, owned and controlled by its members. In a joint-stock company the members are known as shareholders, and each of their shares in the ownership, control, and profits of the corporation is determined by the portion of shares in the company that they own. Thus a person who owns a quarter of the shares of a joint-stock company owns a quarter of the company, is entitled to a quarter of the profit (or at least a quarter of the profit given to shareholders as dividends) and has a quarter of the votes capable of being cast at general meetings. In another kind of corporation, the legal document which established the corporation or which contains its current rules will determine the requirements for membership in the corporation. What these requirements are depends on the kind of corporation involved. In a worker cooperative, the members are people who work for the cooperative. In a credit union, the members are people who have accounts with the credit union. The day-to-day activities of a corporation are typically controlled by individuals appointed by the members. In some cases, this will be a single individual but more commonly corporations are controlled by a committee or by committees. Broadly speaking, there are two kinds of committee structure. A single committee known as a board of directors is the method favored in most common law countries. Under this model, the board of directors is composed of both executive and non-executive directors, the latter being meant to supervise the former's management of the company. A two-tiered committee structure with a supervisory board and a managing board is common in civil law countries. In countries with co-determination (such as Germany and Sweden), workers elect a fixed fraction of the corporation's board. Formation Historically, corporations were created by a charter granted by the government. Today, corporations are usually registered with the state, province, or national government and regulated by the laws enacted by that government. Registration is the main prerequisite to the corporation's assumption of limited liability. The law sometimes requires the corporation to designate its principal address, as well as a registered agent (a person or company designated to receive legal service of process). It may also be required to designate an agent or other legal representatives of the corporation. Generally, a corporation files articles of incorporation with the government, laying out the general nature of the corporation, the amount of stock it is authorized to issue, and the names and addresses of directors. Once the articles are approved, the corporation's directors meet to create bylaws that govern the internal functions of the corporation, such as meeting procedures and officer positions. The law of the jurisdiction in which a corporation operates will regulate most of its internal activities, as well as its finances. If a corporation operates outside its home state, it is often required to register with other governments as a foreign corporation, and is almost always subject to laws of its host state pertaining to employment, crimes, contracts, civil actions, and the like. Naming Corporations generally have a distinct name. Historically, some corporations were named after the members of their boards of directors: for example, the "President and Fellows of Harvard College" is the name of one of the two governing boards of Harvard University, but it is also the exact name under which Harvard was legally incorporated. Nowadays, corporations in most jurisdictions may have a distinct name that does not need to make reference to the members of their boards. In Canada, this possibility is taken to its logical extreme: many smaller Canadian corporations have no names at all, merely numbers based on a registration number (for example, "12345678 Ontario Limited"), which is assigned by the provincial or territorial government where the corporation incorporates. In most countries, corporate names include a term or an abbreviation that denotes the corporate status of the entity (for example, "Incorporated" or "Inc." in the United States) or the limited liability of its members (for example, "Limited" or "Ltd."). These terms vary by jurisdiction and language. In some jurisdictions, they are mandatory, and in others, such as California, they are not. Their use puts everybody on constructive notice that they are dealing with an entity whose liability is limited: one can only collect from whatever assets the entity still controls when one obtains a judgment against it. Some jurisdictions do not allow the use of the word "company" alone to denote corporate status, since the word "company" may refer to a partnership or some other form of collective ownership (in the United States it can be used by a sole proprietorship but this is not generally the case elsewhere). Personhood Despite not being human beings, corporations have been ruled legal persons in a few countries, and have many of the same rights as natural persons do. For example, a corporation can own property, and can sue or be sued for as long as it exists. Corporations can exercise human rights against real individuals and the state, and they can themselves be responsible for human rights violations. Corporations can be "dissolved" either by statutory operation, the order of the court, or voluntary action on the part of shareholders. Insolvency may result in a form of corporate failure, when creditors force the liquidation and dissolution of the corporation under court order, but it most often results in a restructuring of corporate holdings. Corporations can even be convicted of special criminal offenses in the UK, such as fraud and corporate manslaughter. However, corporations are not considered living entities in the way that humans are. Legal scholars and others, such as Joel Bakan, have observed that a business corporation created as a "legal person" has a psychopathic personality because it is required to elevate its own interests above those of others even when this inflicts major risks and grave harms on the public or on other third-parties. Such critics note that the legal mandate of the corporation to focus exclusively on corporate profits and self interest often victimizes employees, customers, the public at large, and/or the natural resources. The political theorist David Runciman notes that corporate personhood forms a fundamental part of the modern history of the idea of the state, and believes the idea of the corporation as legal person can help to clarify the role of citizens as political stakeholders, and to break down the sharp conceptual dichotomy between the state and the people or the individual, a distinction that, on his account, is "increasingly unable to meet the demands placed on the state in the modern world".

had the right to own property and make contracts, to receive gifts and legacies, to sue and be sued, and, in general, to perform legal acts through representatives. Private associations were granted designated privileges and liberties by the emperor. The concept of the corporation was revived in the Middle Ages with the recovery and annotation of Justinian's Corpus Juris Civilis by the glossators and their successors the commentators in the 11th–13th centuries. Particularly important in this respect were the Italian jurists Bartolus de Saxoferrato and Baldus de Ubaldis, the latter of whom connected the corporation to the metaphor of the body politic to describe the state. Entities which carried on business and were the subjects of legal rights were found in ancient Rome, and the Maurya Empire in ancient India. In medieval Europe, churches became incorporated, as did local governments, such as the City of London Corporation. The point was that the incorporation would survive longer than the lives of any particular member, existing in perpetuity. The alleged oldest commercial corporation in the world, the Stora Kopparberg mining community in Falun, Sweden, obtained a charter from King Magnus Eriksson in 1347. In medieval times, traders would do business through common law constructs, such as partnerships. Whenever people acted together with a view to profit, the law deemed that a partnership arose. Early guilds and livery companies were also often involved in the regulation of competition between traders. Mercantilism Dutch and English chartered companies, such as the Dutch East India Company (VOC) and the Hudson's Bay Company, were created to lead the colonial ventures of European nations in the 17th century. Acting under a charter sanctioned by the Dutch government, the Dutch East India Company defeated Portuguese forces and established itself in the Moluccan Islands in order to profit from the European demand for spices. Investors in the VOC were issued paper certificates as proof of share ownership, and were able to trade their shares on the original Amsterdam Stock Exchange. Shareholders were also explicitly granted limited liability in the company's royal charter. In England, the government created corporations under a royal charter or an Act of Parliament with the grant of a monopoly over a specified territory. The best-known example, established in 1600, was the East India Company of London. Queen Elizabeth I granted it the exclusive right to trade with all countries to the east of the Cape of Good Hope. Some corporations at this time would act on the government's behalf, bringing in revenue from its exploits abroad. Subsequently, the company became increasingly integrated with English and later British military and colonial policy, just as most corporations were essentially dependent on the Royal Navy's ability to control trade routes. Labeled by both contemporaries and historians as "the grandest society of merchants in the universe", the English East India Company would come to symbolize the dazzlingly rich potential of the corporation, as well as new methods of business that could be both brutal and exploitative. On 31 December 1600, Queen Elizabeth I granted the company a 15-year monopoly on trade to and from the East Indies and Africa. By 1711, shareholders in the East India Company were earning a return on their investment of almost 150 per cent. Subsequent stock offerings demonstrated just how lucrative the Company had become. Its first stock offering in 1713–1716 raised £418,000, its second in 1717–1722 raised £1.6 million. A similar chartered company, the South Sea Company, was established in 1711 to trade in the Spanish South American colonies, but met with less success. The South Sea Company's monopoly rights were supposedly backed by the Treaty of Utrecht, signed in 1713 as a settlement following the War of the Spanish Succession, which gave Great Britain an asiento to trade in the region for thirty years. In fact, the Spanish remained hostile and let only one ship a year enter. Unaware of the problems, investors in Britain, enticed by extravagant promises of profit from company promoters bought thousands of shares. By 1717, the South Sea Company was so wealthy (still having done no real business) that it assumed the public debt of the British government. This accelerated the inflation of the share price further, as did the Bubble Act 1720, which (possibly with the motive of protecting the South Sea Company from competition) prohibited the establishment of any companies without a Royal Charter. The share price rose so rapidly that people began buying shares merely in order to sell them at a higher price, which in turn led to higher share prices. This was the first speculative bubble the country had seen, but by the end of 1720, the bubble had "burst", and the share price sank from £1000 to under £100. As bankruptcies and recriminations ricocheted through government and high society, the mood against corporations and errant directors was bitter. In the late 18th century, Stewart Kyd, the author of the first treatise on corporate law in English, defined a corporation as: Development of modern company law Due to the late 18th century abandonment of mercantilist economic theory and the rise of classical liberalism and laissez-faire economic theory due to a revolution in economics led by Adam Smith and other economists, corporations transitioned from being government or guild affiliated entities to being public and private economic entities free of governmental directions. Smith wrote in his 1776 work The Wealth of Nations that mass corporate activity could not match private entrepreneurship, because people in charge of others' money would not exercise as much care as they would with their own. Deregulation The British Bubble Act 1720s prohibition on establishing companies remained in force until its repeal in 1825. By this point, the Industrial Revolution had gathered pace, pressing for legal change to facilitate business activity. The repeal was the beginning of a gradual lifting on restrictions, though business ventures (such as those chronicled by Charles Dickens in Martin Chuzzlewit) under primitive companies legislation were often scams. Without cohesive regulation, proverbial operations like the "Anglo-Bengalee Disinterested Loan and Life Assurance Company" were undercapitalized ventures promising no hope of success except for richly paid promoters. The process of incorporation was possible only through a royal charter or a private act and was limited, owing to Parliament's jealous protection of the privileges and advantages thereby granted. As a result, many businesses came to be operated as unincorporated associations with possibly thousands of members. Any consequent litigation had to be carried out in the joint names of all the members and was almost impossibly cumbersome. Though Parliament would sometimes grant a private act to allow an individual to represent the whole in legal proceedings, this was a narrow and necessarily costly expedient, allowed only to established companies. Then, in 1843, William Gladstone became the chairman of a Parliamentary Committee on Joint Stock Companies, which led to the Joint Stock Companies Act 1844, regarded as the first modern piece of company law. The Act created the Registrar of Joint Stock Companies, empowered to register companies by a two-stage process. The first, provisional, stage cost £5 and did not confer corporate status, which arose after completing the second stage for another £5. For the first time in history, it was possible for ordinary people through a simple registration procedure to incorporate. The advantage of establishing a company as a separate legal person was mainly administrative, as a unified entity under which the rights and duties of all investors and managers could be channeled. Limited liability However, there was still no limited liability and company members could still be held responsible for unlimited losses by the company. The next, crucial development, then, was the Limited Liability Act 1855, passed at the behest of the then Vice President of the Board of Trade, Robert Lowe. This allowed investors to limit their liability in the event of business failure to the amount they invested in the company – shareholders were still liable directly to creditors, but just for the unpaid portion of their shares. (The principle that shareholders are liable to the corporation had been introduced in the Joint Stock Companies Act 1844). The 1855 Act allowed limited liability to companies of more than 25 members (shareholders). Insurance companies were excluded from the act, though it was standard practice for insurance contracts to exclude action against individual members. Limited liability for insurance companies was allowed by the Companies Act 1862. This prompted the English periodical The Economist to write in 1855 that "never, perhaps, was a change so vehemently and generally demanded, of which the importance was so much overrated." The major error of this judgment was recognised by the same magazine more than 70 years later, when it claimed that, "[t]he economic historian of the future... may be inclined to assign to the nameless inventor of the principle of limited liability, as applied to trade corporations, a place of honour with Watt and Stephenson, and other pioneers of the Industrial Revolution. " These two features – a simple registration procedure and limited liability – were subsequently codified into the landmark 1856 Joint Stock Companies Act. This was subsequently consolidated with a number of other statutes in the Companies Act 1862, which remained in force for the rest of the century, up to and including the time of the decision in Salomon v A Salomon & Co Ltd. The legislation shortly gave way to a railway boom, and from then, the numbers of companies formed soared. In the later nineteenth century, depression took hold, and just as company numbers had boomed, many began to implode and fall into insolvency. Much strong academic, legislative and judicial opinion was opposed to the notion that businessmen could escape accountability for their role in the failing businesses. Further developments In 1892, Germany introduced the Gesellschaft mit beschränkter Haftung with a separate legal personality and limited liability even if all the shares of the company were held by only one person. This inspired other countries to introduce corporations of this kind. The last significant development in the history of companies was the 1897 decision of the House of Lords in Salomon v. Salomon & Co. where
new games after the debut of the second system before its eventual demise; several of these were developed at Fairchild before they sold it off. The major changes were in design, with the controllers being removable from the base unit instead of being wired directly into it; the controller storage was moved to the rear of the unit, and the sound was now mixed into the RF TV signal so the unit no longer needed a speaker. Electronics were also simplified, with custom logic chips instead of standard logic, resulting in a much smaller circuit board. This version also featured a simpler and more modern-looking case design. Licensed variants A number of licensed versions were released in Europe, including the Luxor Video Entertainment System in Sweden, Adman Grandstand Video Entertainment Computer in the UK, the SABA Videoplay, ITT Telematch Processor and Nordmende Color TelePlay µP from Germany, and the Dumont Videoplay and Barco Challenger from the Barco/Dumont company in Italy and Belgium. Design The F8 was very complex compared to the typical integrated circuits of the day and had more inputs and outputs than other contemporary chips. Because chip packaging was not initially available with enough pins, the F8 used in the original form of the VES/Channel F (replaced by System II) was instead fabricated as a pair of chips that had to be used together to form a complete CPU. However, due to the F8's design, there was a considerable savings in terms of pins that enabled the inclusion of 64 bytes of internal scratchpad RAM. A single-chip variant of the F8 was used by both the System II and the VideoBrain computer system. The Channel F is able to use one plane of graphics and one of four background colors per line, with three plot colors to choose from (red, green, and blue) that turned into white if the background is set to black, at a resolution of 128 × 64, with approximately 102 × 58 pixels visible and help from 64 bytes of system RAM, half the amount of the later Atari 2600. The Maze game (cartridge 10) required 1K of on-cartridge static RAM, adding to the cost to manufacture it. The Chess game contained considerably more on-cartridge RAM than that. The F8 processor at the heart of the console is able to produce enough AI to allow for player versus computer matches, a first in console history. All previous machines required a human opponent. Tic-Tac-Toe on Videocart-1 had this feature, it was only for one player against the machine. The same is true for the chess game, which would have very long turn times for the computer as the game progressed. In the original unit, sound is played through an internal speaker, rather than the TV set. However, the System II passed sound to the television through the RF modulator. The Channel F is also the first video game console to feature a pause function; There is a 'Hold' button on the main unit of the console which allows players to freeze the game and change several game settings in the meantime. Controllers The controllers are a joystick without a base; the main body is a large handgrip with a triangular "cap" on top, the top being the portion that actually moved for eight-way directional control. It could be used as both a joystick and paddle (twist), and not only could it be pushed down to operate as a fire button, it could be pulled up as well. The model 1 unit contained a small compartment for storing the controllers when moving it. The System II featured detachable controllers and had two holders at the back to wind the cable around and to store the controller in. Zircon later offered a special control that featured an action button on the front of the joystick. It was marketed by Zircon as "Channel F Jet-Stick" in a letter sent out to registered owners before Christmas 1982. The functions printed on the console is how they work in the built-in games and also some of the original games: all buttons (except reset) are controlled by the programming and can be used for anything the programmer decides. One feature unique of the console is the 'hold' button, which allows the player to freeze the game, change the time or change the speed of the game. The hold function is not universal (like the hardwired reset). Despite the failure of the Channel F, the joystick's design was so popular—Creative Computing called it "outstanding"— that Zircon also released an Atari joystick port-compatible version, the Video Command Joystick, first released without the extra fire button. Before that, only the downwards plunge motion was connected and acted as the fire button; the pull-up and twist actions were not connected to anything.

directly into it; the controller storage was moved to the rear of the unit, and the sound was now mixed into the RF TV signal so the unit no longer needed a speaker. Electronics were also simplified, with custom logic chips instead of standard logic, resulting in a much smaller circuit board. This version also featured a simpler and more modern-looking case design. Licensed variants A number of licensed versions were released in Europe, including the Luxor Video Entertainment System in Sweden, Adman Grandstand Video Entertainment Computer in the UK, the SABA Videoplay, ITT Telematch Processor and Nordmende Color TelePlay µP from Germany, and the Dumont Videoplay and Barco Challenger from the Barco/Dumont company in Italy and Belgium. Design The F8 was very complex compared to the typical integrated circuits of the day and had more inputs and outputs than other contemporary chips. Because chip packaging was not initially available with enough pins, the F8 used in the original form of the VES/Channel F (replaced by System II) was instead fabricated as a pair of chips that had to be used together to form a complete CPU. However, due to the F8's design, there was a considerable savings in terms of pins that enabled the inclusion of 64 bytes of internal scratchpad RAM. A single-chip variant of the F8 was used by both the System II and the VideoBrain computer system. The Channel F is able to use one plane of graphics and one of four background colors per line, with three plot colors to choose from (red, green, and blue) that turned into white if the background is set to black, at a resolution of 128 × 64, with approximately 102 × 58 pixels visible and help from 64 bytes of system RAM, half the amount of the later Atari 2600. The Maze game (cartridge 10) required 1K of on-cartridge static RAM, adding to the cost to manufacture it. The Chess game contained considerably more on-cartridge RAM than that.

Several of these cartridges were capable of playing more than one game and were typically priced at . The Videocarts were yellow and approximately the size and overall texture of an 8 track cartridge. They usually featured colorful label artwork. The earlier artwork was created by nationally known artist Tom Kamifuji and art directed by Nick Talesfore. The console contained two built-in
of a standard ordering for the letters of the alphabet in question. (The system is not limited to alphabets in the strict technical sense; languages that use a syllabary or abugida, for example Cherokee, can use the same ordering principle provided there is a set ordering for the symbols used.) To decide which of two strings comes first in alphabetical order, initially their first letters are compared. The string whose first letter appears earlier in the alphabet comes first in alphabetical order. If the first letters are the same, then the second letters are compared, and so on, until the order is decided. (If one string runs out of letters to compare, then it is deemed to come first; for example, "cart" comes before "carthorse".) The result of arranging a set of strings in alphabetical order is that words with the same first letter are grouped together, and within such a group words with the same first two letters are grouped together, and so on. Capital letters are typically treated as equivalent to their corresponding lowercase letters. (For alternative treatments in computerized systems, see Automated collation, below.) Certain limitations, complications, and special conventions may apply when alphabetical order is used: When strings contain spaces or other word dividers, the decision must be taken whether to ignore these dividers or to treat them as symbols preceding all other letters of the alphabet. For example, if the first approach is taken then "car park" will come after "carbon" and "carp" (as it would if it were written "carpark"), whereas in the second approach "car park" will come before those two words. The first rule is used in many (but not all) dictionaries, the second in telephone directories (so that Wilson, Jim K appears with other people named Wilson, Jim and not after Wilson, Jimbo). Abbreviations may be treated as if they were spelt out in full. For example, names containing "St." (short for the English word Saint) are often ordered as if they were written out as "Saint". There is also a traditional convention in English that surnames beginning Mc and M are listed as if those prefixes were written Mac. Strings that represent personal names will often be listed by alphabetical order of surname, even if the given name comes first. For example, Juan Hernandes and Brian O'Leary should be sorted as "Hernandes, Juan" and "O'Leary, Brian" even if they are not written this way. Very common initial words, such as The in English, are often ignored for sorting purposes. So The Shining would be sorted as just "Shining" or "Shining, The". When some of the strings contain numerals (or other non-letter characters), various approaches are possible. Sometimes such characters are treated as if they came before or after all the letters of the alphabet. Another method is for numbers to be sorted alphabetically as they would be spelled: for example 1776 would be sorted as if spelled out "seventeen seventy-six", and 24 heures du Mans as if spelled "vingt-quatre..." (French for "twenty-four"). When numerals or other symbols are used as special graphical forms of letters, as in 1337 for leet or Se7en for the movie title Seven, they may be sorted as if they were those letters. Languages have different conventions for treating modified letters and certain letter combinations. For example, in Spanish the letter ñ is treated as a basic letter following n, and the digraphs ch and ll were formerly (until 1994) treated as basic letters following c and l, although they are now alphabetized as two-letter combinations. A list of such conventions for various languages can be found at . In several languages the rules have changed over time, and so older dictionaries may use a different order than modern ones. Furthermore, collation may depend on use. For example, German dictionaries and telephone directories use different approaches. Radical-and-stroke sorting See also Indexing of Chinese characters Another form of collation is radical-and-stroke sorting, used for non-alphabetic writing systems such as the hanzi of Chinese and the kanji of Japanese, whose thousands of symbols defy ordering by convention. In this system, common components of characters are identified; these are called radicals in Chinese and logographic systems derived from Chinese. Characters are then grouped by their primary radical, then ordered by number of pen strokes within radicals. When there is no obvious radical or more than one radical, convention governs which is used for collation. For example, the Chinese character
alterations, the most obvious being case conversion (often to uppercase, for historical reasons) before comparison of ASCII values. In many collation algorithms, the comparison is based not on the numerical codes of the characters, but with reference to the collating sequence''' – a sequence in which the characters are assumed to come for the purpose of collation – as well as other ordering rules appropriate to the given application. This can serve to apply the correct conventions used for alphabetical ordering in the language in question, dealing properly with differently cased letters, modified letters, digraphs, particular abbreviations, and so on, as mentioned above under Alphabetical order, and in detail in the Alphabetical order article. Such algorithms are potentially quite complex, possibly requiring several passes through the text. Problems are nonetheless still common when the algorithm has to encompass more than one language. For example, in German dictionaries the word ökonomisch comes between offenbar and olfaktorisch, while Turkish dictionaries treat o and ö as different letters, placing oyun before öbür. A standard algorithm for collating any collection of strings composed of any standard Unicode symbols is the Unicode Collation Algorithm. This can be adapted to use the appropriate collation sequence for a given language by tailoring its default collation table. Several such tailorings are collected in Common Locale Data Repository. Sort keys In some applications, the strings by which items are collated may differ from the identifiers that are displayed. For example, The Shining might be sorted as Shining, The (see Alphabetical order above), but it may still be desired to display it as The Shining. In this case two sets of strings can be stored, one for display purposes, and another for collation purposes. Strings used for collation in this way are called sort keys''. Issues with numbers Sometimes, it is desired to order text with embedded numbers using proper numerical order. For example, "Figure 7b" goes before "Figure 11a", even though '7' comes after '1' in Unicode. This can be extended to Roman numerals. This behavior is not particularly difficult to produce as long as only integers are to be sorted, although it can slow down sorting significantly. For example, Microsoft Windows does this when sorting file names. Sorting decimals properly is a bit more difficult, because different locales use different symbols for a decimal point, and sometimes the same character used as a decimal point is also used as a separator, for example "Section 3.2.5". There is no universal answer for how to sort such strings; any rules are application dependent. Labeling of ordered items In some contexts, numbers and letters are used not so much as a basis for establishing an ordering, but as a means of labeling items that are already ordered. For example, pages, sections, chapters, and the like, as well as the items of lists, are frequently "numbered" in this way. Labeling series that may be used include ordinary Arabic numerals (1, 2, 3, ...), Roman numerals (I, II, III, ... or i, ii, iii, ...), or letters (A, B, C, ... or a, b, c, ...). (An alternative method for indicating list items, without numbering them, is to use a bulleted list.) When letters of an alphabet are used for this purpose of enumeration, there are certain language-specific conventions as to which letters are used. For example, the Russian letters Ъ and Ь (which in writing are only used for modifying the preceding consonant), and usually also Ы, Й, and Ё, are omitted. Also in many languages that use extended Latin script, the modified letters are often not used in enumeration. See also Alphabetical order Asciibetical order Sorting

are maintained during times of stress. Level 3 - Defined It is characteristic of processes at this level that there are sets of defined and documented standard processes established and subject to some degree of improvement over time. These standard processes are in place. The processes may not have been systematically or repeatedly used - sufficient for the users to become competent or the process to be validated in a range of situations. This could be considered a developmental stage - with use in a wider range of conditions and user competence development the process can develop to next level of maturity. Level 4 - Managed (Capable) It is characteristic of processes at this level that, using process metrics, effective achievement of the process objectives can be evidenced across a range of operational conditions. The suitability of the process in multiple environments has been tested and the process refined and adapted. Process users have experienced the process in multiple and varied conditions, and are able to demonstrate competence. The process maturity enables adaptions to particular projects without measurable losses of quality or deviations from specifications. Process Capability is established from this level. (Example - surgeon performing an operation hundreds of times with levels of negative outcome approaching zero). Level 5 - Optimizing (Efficient)It is a characteristic of processes at this level that the focus is on continually improving process performance through both incremental and innovative technological changes/improvements. At maturity level 5, processes are concerned with addressing statistical common causes of process variation and changing the process (for example, to shift the mean of the process performance) to improve process performance. This would be done at the same time as maintaining the likelihood of achieving the established quantitative process-improvement objectives. Between 2008 and 2019, about 12% of appraisals given were at maturity levels 4 and 5. Critique The model was originally intended to evaluate the ability of government contractors to perform a software project. It has been used for and may be suited to that purpose, but critics pointed out that process maturity according to the CMM was not necessarily mandatory for successful software development. Software process framework The software process framework documented is intended to guide those wishing to assess an organization's or project's consistency with the Key Process Areas. For each maturity level there are five checklist types: {| class="wikitable" |- ! Type ! Description |- | Policy |Describes the policy contents and KPA goals recommended by the Key Process Areas. |- | Standard |Describes the recommended content of select work products described in the Key Process Areas. |- | Process | Describes the process information content recommended by the Key Process Areas. These are refined into checklists for: Roles, entry criteria, inputs, activities, outputs, exit criteria, reviews and audits, work products managed and controlled, measurements, documented procedures, training, and tools |- | Procedure | Describes the recommended content of documented procedures described in the Key Process Areas. |- | Level overview | Provides an overview of an entire maturity level. These are further refined into checklists for: Key Process Areas purposes, goals, policies, and standards; process descriptions; procedures; training; tools; reviews and audits; work products; measurements |} See also Capability Immaturity Model Capability Maturity
organizations mature their processes in stages based on solving process problems in a specific order. Humphrey based his approach on the staged evolution of a system of software development practices within an organization, rather than measuring the maturity of each separate development process independently. The CMM has thus been used by different organizations as a general and powerful tool for understanding and then improving general business process performance. Watts Humphrey's Capability Maturity Model (CMM) was published in 1988 and as a book in 1989, in Managing the Software Process. Organizations were originally assessed using a process maturity questionnaire and a Software Capability Evaluation method devised by Humphrey and his colleagues at the Software Engineering Institute. The full representation of the Capability Maturity Model as a set of defined process areas and practices at each of the five maturity levels was initiated in 1991, with Version 1.1 being completed in January 1993. The CMM was published as a book in 1995 by its primary authors, Mark C. Paulk, Charles V. Weber, Bill Curtis, and Mary Beth Chrissis. United States of America New York, USA. Capability Maturity Model Integration The CMM model's application in software development has sometimes been problematic. Applying multiple models that are not integrated within and across an organization could be costly in training, appraisals, and improvement activities. The Capability Maturity Model Integration (CMMI) project was formed to sort out the problem of using multiple models for software development processes, thus the CMMI model has superseded the CMM model, though the CMM model continues to be a general theoretical process capability model used in the public domain. Adapted to other processes The CMM was originally intended as a tool to evaluate the ability of government contractors to perform a contracted software project. Though it comes from the area of software development, it can be, has been, and continues to be widely applied as a general model of the maturity of process (e.g., IT service management processes) in IS/IT (and other) organizations. Model topics Maturity models A maturity model can be viewed as a set of structured levels that describe how well the behaviors, practices and processes of an organization can reliably and sustainably produce required outcomes. A maturity model can be used as a benchmark for comparison and as an aid to understanding - for example, for comparative assessment of different organizations where there is something in common that can be used as a basis for comparison. In the case of the CMM, for example, the basis for comparison would be the organizations' software development processes. Structure The model involves five aspects: Maturity Levels: a 5-level process maturity continuum - where the uppermost (5th) level is a notional ideal state where processes would be systematically managed by a combination of process optimization and continuous process improvement. Key Process Areas: a Key Process Area identifies a cluster of related activities that, when performed together, achieve a set of goals considered important. Goals: the goals of a key process area summarize the states that must exist for that key process area to have been implemented in an effective and lasting way. The extent to which the goals have been accomplished is an indicator of how much capability the organization has established at that maturity level. The goals signify the scope, boundaries, and intent of each key process area.
method of production had been independently discovered by Ebele in Germany prior to Schiessler and Ross, but that this was not known by the Allies. Urbański provides details of five methods of production, and he refers to this method as the (German) E-method. UK, U.S., and Canadian production and development At the beginning of the 1940s, the major U.S. explosive manufacturers, E. I. du Pont de Nemours & Company and Hercules, had several decades of experience of manufacturing trinitrotoluene (TNT) and had no wish to experiment with new explosives. U.S. Army Ordnance held the same viewpoint and wanted to continue using TNT. RDX had been tested by Picatinny Arsenal in 1929, and it was regarded as too expensive and too sensitive. The Navy proposed to continue using ammonium picrate. In contrast, the National Defense Research Committee (NDRC), who had visited The Royal Arsenal, Woolwich, thought new explosives were necessary. James B. Conant, chairman of Division B, wished to involve academic research into this area. Conant therefore set up an experimental explosives research laboratory at the Bureau of Mines, Bruceton, Pennsylvania, using Office of Scientific Research and Development (OSRD) funding. Woolwich method In 1941, the UK's Tizard Mission visited the U.S. Army and Navy departments and part of the information handed over included details of the "Woolwich" method of manufacture of RDX and its stabilisation by mixing it with beeswax. The UK was asking that the U.S. and Canada, combined, supply (440,000 lb) of RDX per day. A decision was taken by William H. P. Blandy, chief of the Bureau of Ordnance, to adopt RDX for use in mines and torpedoes. Given the immediate need for RDX, the U.S. Army Ordnance, at Blandy's request, built a plant that copied the equipment and process used at Woolwich. The result was the Wabash River Ordnance Works run by E. I. du Pont de Nemours & Company. At that time, this works had the largest nitric acid plant in the world. The Woolwich process was expensive: it needed of strong nitric acid for every pound of RDX. By early 1941, the NDRC was researching new processes. The Woolwich or direct nitration process has at least two serious disadvantages: (1) it used large amounts of nitric acid and (2) at least one-half of the formaldehyde is lost. One mole of hexamethylenetetramine could produce at most one mole of RDX. At least three laboratories with no previous explosive experience were instructed to develop better production methods for RDX; they were based at Cornell, Michigan, and Pennsylvania State universities. Werner Emmanuel Bachmann, from Michigan, successfully developed the "combination process" by combining the Canadian process with direct nitration. The combination process required large quantities of acetic anhydride instead of nitric acid in the old British "Woolwich process". Ideally, the combination process could produce two moles of RDX from each mole of hexamethylenetetramine. The vast production of RDX could not continue to rely on the use of natural beeswax to desensitize the RDX. A substitute stabilizer based on petroleum was developed at the Bruceton Explosives Research Laboratory. Bachmann process The NDRC instructed three companies to develop pilot plants. They were the Western Cartridge Company, E. I. du Pont de Nemours & Company, and Tennessee Eastman Company, part of Eastman Kodak. At the Eastman Chemical Company (TEC), a leading manufacturer of acetic anhydride, Werner Emmanuel Bachmann developed a continuous-flow process for RDX. RDX was crucial to the war effort and the current batch-production process was too slow. In February 1942, TEC began producing small amounts of RDX at its Wexler Bend pilot plant, which led to the U.S. government authorizing TEC to design and build Holston Ordnance Works (H.O.W.) in June 1942. By April 1943, RDX was being manufactured there. At the end of 1944, the Holston plant and the Wabash River Ordnance Works, which used the Woolwich process, were producing (50 million pounds) of Composition B per month. The U.S. Bachmann process for RDX was found to be richer in HMX than the United Kingdom's RDX. This later led to a RDX plant using the Bachmann process being set up at ROF Bridgwater in 1955 to produce both RDX and HMX. Military compositions The United Kingdom's intention in World War II was to use "desensitised" RDX. In the original Woolwich process, RDX was phlegmatized with beeswax, but later paraffin wax was used, based on the work carried out at Bruceton. In the event the UK was unable to obtain sufficient RDX to meet its needs, some of the shortfall was met by substituting amatol, a mixture of ammonium nitrate and TNT. Karl Dönitz was reputed to have claimed that "an aircraft can no more kill a U-boat than a crow can kill a mole". Nonetheless, by May 1942 Wellington bombers began to deploy depth charges containing Torpex, a mixture of RDX, TNT, and aluminium, which had up to 50 percent more destructive power than TNT-filled depth charges. Considerable quantities of the RDX–TNT mixture were produced at the Holston Ordnance Works, with Tennessee Eastman developing an automated mixing and cooling process based around the use of stainless steel conveyor belts. Terrorism A Semtex bomb was used in the Pan Am Flight 103 (known also as the Lockerbie) bombing in 1988. A belt laden with of RDX explosives tucked under the dress of the assassin was used in the assassination of former Indian prime minister Rajiv Gandhi in 1991. The 1993 Bombay bombings used RDX placed into several vehicles as bombs. RDX was the main component used for the 2006 Mumbai train bombings and the Jaipur bombings in 2008. It also is believed to be the explosive used in the 2010 Moscow Metro bombings. Traces of RDX were found on pieces of wreckage from 1999 Russian apartment bombings and 2004 Russian aircraft bombings. Further reports on the bombs used in the 1999 apartment bombings indicated that while RDX was not a part of the main charge, each bomb contained plastic explosive used as a booster charge. Ahmed Ressam, the al-Qaeda Millennium Bomber, used a small quantity of RDX as one of the components in the bomb that he prepared to detonate in Los Angeles International Airport on New Year's Eve 1999-2000; the bomb could have produced a blast forty times greater than that of a devastating

In July 2012, the Kenyan government arrested two Iranian nationals and charged them with illegal possession of of RDX. According to the Kenyan Police, the Iranians planned to use the RDX for "attacks on Israeli, US, UK and Saudi Arabian targets". RDX was used in the assassination of Lebanese Prime Minister Rafic Hariri on February 14, 2005. In the 2019 Pulwama attack in India, 250 kg of high-grade RDX was used by Jaish-e-Mohammed. The attack resulted in the deaths of 44 Central Reserve Police Force (CRPF) personnel as well as the attacker. Stability RDX has a high nitrogen content and a high O:C ratio, both of which indicate its explosive potential for formation of N2 and CO2. RDX undergoes a deflagration to detonation transition (DDT) in confinement and certain circumstances. The velocity of detonation of RDX at a density of 1.76 g/cm3 is 8750 m/s. It starts to decompose at approximately 170 °C and melts at 204 °C. At room temperature, it is very stable. It burns rather than explodes. It detonates only with a detonator, being unaffected even by small arms fire. This property makes it a useful military explosive. It is less sensitive than pentaerythritol tetranitrate (PETN). Under normal conditions, RDX has a Figure of Insensitivity of exactly 80 (RDX defines the reference point). RDX sublimes in vacuum, which restricts or prevents its use in some applications. RDX, when exploded in air, has about 1.5 times the explosive energy of TNT per unit weight and about 2.0 times per unit volume. RDX is insoluble in water, with solubility 0.05975 g/L at temperature of 25 °C. Toxicity The substance's toxicity has been studied for many years. RDX has caused convulsions (seizures) in military field personnel ingesting it, and in munition workers inhaling its dust during manufacture. At least one fatality was attributed to RDX toxicity in a European munitions manufacturing plant. During the Vietnam War, at least 40 American soldiers were hospitalized with composition C-4 (which is 91% RDX) intoxication from December 1968 to December 1969. C-4 was frequently used by soldiers as a fuel to heat food, and the food was generally mixed by the same knife that was used to cut C-4 into small pieces prior to burning. Soldiers were exposed to C-4 either due to inhaling the fumes, or due to ingestion, made possible by many small particles adhering to the knife having been deposited into the cooked food. The symptom complex involved nausea, vomiting, generalized seizures, and prolonged postictal confusion and amnesia; which indicated toxic encephalopathy. Oral toxicity of RDX depends on its physical form; in rats, the LD50

rooted in Second Temple Judaism, but the two religions diverged in the first centuries of the Christian Era. Christianity emphasizes correct belief (or orthodoxy), focusing on the New Covenant as mediated through Jesus Christ, as recorded in the New Testament. Judaism places emphasis on correct conduct (or orthopraxy), focusing on the Mosaic covenant, as recorded in the Torah and Talmud. Christians generally believe in individual salvation from sin through receiving Jesus Christ as their Lord and savior Son of God. Jews believe in individual and collective participation in an eternal dialogue with God through tradition, rituals, prayers and ethical actions. Christianity generally believes in a Triune God, one person of whom became human. Judaism emphasizes the Oneness of God and rejects the Christian concept of God in human form. Jewish self-identification Judaism's purpose is to carry out what it holds to be the covenant between God and the Jewish people. The Torah (lit. "teaching"), both written and oral, tells the story of this covenant, and provides Jews with the terms of the covenant. The Oral Torah is the primary guide for Jews to abide by these terms, as expressed in tractate Gittin 60b, "the Holy One, Blessed be He, did not make His covenant with Israel except by virtue of the Oral Law" to help them learn how to live a holy life, and to bring holiness, peace and love into the world and into every part of life, so that life may be elevated to a high level of kedushah, originally through study and practice of the Torah, and since the destruction of the Second Temple, through prayer as expressed in tractate Sotah 49a "Since the destruction of the Temple, every day is more cursed than the preceding one; and the existence of the world is assured only by the kedusha...and the words spoken after the study of Torah." Since the adoption of the Amidah, the acknowledgement of God through the declaration from Isaiah 6:3 "Kadosh [holy], kadosh, kadosh, is HaShem, Master of Legions; the whole world is filled with His glory". as a replacement for the study of Torah, which is a daily obligation for a Jew, and sanctifies God in itself. This continuous maintenance of relationship between the individual Jew and God through either study, or prayer repeated three times daily, is the confirmation of the original covenant. This allows the Jewish people as a community to strive and fulfill the prophecy "I, the Lord, have called you in righteousness, and will hold your hand and keep you. And I will establish you as a covenant of the people, for a light unto the nations." (i.e., a role model) over the course of history, and a part of the divine intent of bringing about an age of peace and sanctity where ideally a faithful life and good deeds should be ends in themselves, not means. See also Jewish principles of faith. According to Christian theologian Alister McGrath, the Jewish Christians affirmed every aspect of then contemporary Second Temple Judaism with the addition of the belief that Jesus was the messiah, with Isaiah 49:6, "an explicit parallel to 42:6" quoted by Paul the Apostle in Acts 13:47 and reinterpreted by Justin Martyr. According to Christian writers, most notably Paul, the Bible teaches that people are, in their current state, sinful, and the New Testament reveals that Jesus is both the Son of man and the Son of God, united in the hypostatic union, God the Son, God made incarnate; that Jesus' death by crucifixion was a sacrifice to atone for all of humanity's sins, and that acceptance of Jesus as Savior and Lord saves one from Divine Judgment, giving Eternal life. Jesus is the mediator of the New Covenant. His famous Sermon on the Mount is considered by some Christian scholars to be the proclamation of the New Covenant ethics, in contrast to the Mosaic Covenant of Moses from Mount Sinai. Sacred texts The Hebrew Bible is composed of three parts; the Torah (Instruction, the Septuagint translated the Hebrew to nomos or Law), the Nevi'im (Prophets) and the Ketuvim (Writings). Collectively, these are known as the Tanakh. According to Rabbinic Judaism the Torah was revealed by God to Moses; within it, Jews find 613 Mitzvot (commandments). Rabbinic tradition asserts that God revealed two Torahs to Moses, one that was written down, and one that was transmitted orally. Whereas the written Torah has a fixed form, the Oral Torah is a living tradition that includes not only specific supplements to the written Torah (for instance, what is the proper manner of shechita and what is meant by "Frontlets" in the Shema), but also procedures for understanding and talking about the written Torah (thus, the Oral Torah revealed at Sinai includes debates among rabbis who lived long after Moses). The Oral Law elaborations of narratives in the Bible and stories about the rabbis are referred to as aggadah. It also includes elaboration of the 613 commandments in the form of laws referred to as halakha. Elements of the Oral Torah were committed to writing and edited by Judah HaNasi in the Mishnah in 200 CE; much more of the Oral Torah were committed to writing in the Babylonian and Jerusalem Talmuds, which were edited around 600 CE and 450 CE, respectively. The Talmuds are notable for the way they combine law and lore, for their explication of the midrashic method of interpreting texts, and for their accounts of debates among rabbis, which preserve divergent and conflicting interpretations of the Bible and legal rulings. Since the transcription of the Talmud, notable rabbis have compiled law codes that are generally held in high regard: the Mishneh Torah, the Tur, and the Shulchan Aruch. The latter, which was based on earlier codes and supplemented by the commentary by Moshe Isserles that notes other practices and customs practiced by Jews in different communities, especially among Ashkenazim, is generally held to be authoritative by Orthodox Jews. The Zohar, which was written in the 13th century, is generally held as the most important esoteric treatise of the Jews. All contemporary Jewish movements consider the Tanakh, and the Oral Torah in the form of the Mishnah and Talmuds as sacred, although movements are divided as to claims concerning their divine revelation, and also their authority. For Jews, the Torah—written and oral—is the primary guide to the relationship between God and man, a living document that has unfolded and will continue to unfold whole new insights over the generations and millennia. A saying that captures this goes, "Turn it [the Torah's words] over and over again, for everything is in it." Christians accept the Written Torah and other books of the Hebrew Bible (alternatively called Old Testament) as Scripture, although they generally give readings from the Koine Greek Septuagint translation instead of the Biblical Hebrew/Biblical Aramaic Masoretic Text. Two notable examples are: Isaiah 7:14 – "virgin" instead of "young woman" Psalm 22:16 – "they have pierced my hands and feet" instead of "like a lion, (they are at) my hands and feet" Instead of the traditional Jewish order and names for the books, Christians organize and name the books closer to that found in the Septuagint. Some Christian denominations (such as Anglican, Roman Catholic, and Eastern Orthodox), include a number of books that are not in the Hebrew Bible (the biblical apocrypha or deuterocanonical books or Anagignoskomena, see Development of the Old Testament canon) in their biblical canon that are not in today's Jewish canon, although they were included in the Septuagint. Christians reject the Jewish Oral Torah, which was still in oral, and therefore unwritten, form in the time of Jesus. Covenant theology Christians believe that God has established a New Covenant with people through Jesus, as recorded in the Gospels, Acts of the Apostles, Epistles, and other books collectively called the New Testament (the word testament attributed to Tertullian is commonly interchanged with the word covenant). For some Christians, such as Roman Catholics and Orthodox Christians, this New Covenant includes authoritative sacred traditions and canon law. Others, especially Protestants, reject the authority of such traditions and instead hold to the principle of sola scriptura, which accepts only the Bible itself as the final rule of faith and practice. Anglicans do not believe in sola scriptura. For them scripture is the longest leg of a 3-legged stool: scripture, tradition and reason. Scripture cannot stand on its own since it must be interpreted in the light of the Church's patristic teaching and ecumenical creeds. Additionally, some denominations include the "oral teachings of Jesus to the Apostles", which they believe have been handed down to this day by apostolic succession. Christians refer to the biblical books about Jesus as the New Testament, and to the canon of Hebrew books as the Old Testament. Judaism does not accept the retronymic labeling of its sacred texts as the "Old Testament", and some Jews refer to the New Testament as the Christian Testament or Christian Bible. Judaism rejects all claims that the Christian New Covenant supersedes, abrogates, fulfills, or is the unfolding or consummation of the covenant expressed in the Written and Oral Torahs. Therefore, just as Christianity does not accept that Mosaic law has any authority over Christians, Judaism does not accept that the New Testament has any religious authority over Jews. Law Many Jews view Christians as having quite an ambivalent view of the Torah, or Mosaic law: on one hand Christians speak of it as God's absolute word, but on the other, they apply its commandments with a certain selectivity. Some Jews contend that Christians cite commandments from the Old Testament to support one point of view but then ignore other commandments of a similar class and of equal weight. Examples of this are certain commandments that God states explicitly be a "lasting covenant." Some translate the Hebrew as a "perpetual covenant." Christians explain that such selectivity is based on rulings made by early Jewish Christians in the Book of Acts, at the Council of Jerusalem, that, while believing gentiles did not need to fully convert to Judaism, they should follow some aspects of Torah like avoiding idolatry and fornication and blood. This view is also reflected by modern Judaism, in that Righteous gentiles needn't convert to Judaism and need to observe only the Noahide Laws, which also contain prohibitions against idolatry and fornication and blood. Some Christians agree that Jews who accept Jesus should still observe all of Torah, see for example Dual-covenant theology, based on warnings by Jesus to Jews not to use him as an excuse to disregard it, and they support efforts of those such as Messianic Jews (Messianic Judaism is considered by most Christians and Jews to be a form of Christianity) to do that, but some Protestant forms of Christianity oppose all observance to the Mosaic law, even by Jews, which Luther criticised as Antinomianism. A minority view in Christianity, known as Christian Torah-submission, holds that the Mosaic law as it is written is binding on all followers of God under the New Covenant, even for gentiles, because it views God's commands as "everlasting" and "good." Concepts of God Traditionally, both Judaism and Christianity believe in the God of Abraham, Isaac and Jacob, for Jews the God of the Tanakh, for Christians the God of the Old Testament, the creator of the universe. Judaism and major sects of Christianity reject the view that God is entirely immanent (although some see this as the concept of the Holy Ghost) and within the world as a physical presence, (although Christians believe in the incarnation of God). Both religions reject the view that God is entirely transcendent, and thus separate from the world, as the pre-Christian Greek Unknown God. Both religions reject atheism on one hand and polytheism on the other. Both religions agree that God shares both transcendent and immanent qualities. How these religions resolve this issue is where the religions differ. Christianity posits that God exists as a Trinity; in this view God exists as three distinct persons who share a single divine essence, or substance. In those three there is one, and in that one there are three; the one God is indivisible, while the three persons are distinct and unconfused, God the Father, God the Son, and God the Holy Spirit. It teaches that God became especially immanent in physical form through the Incarnation of God the Son who was born as Jesus of Nazareth, who is believed to be at once fully God and fully human. There are denominations self-describing as Christian who question one or more of these doctrines, however, see Nontrinitarianism. By contrast, Judaism sees God as a single entity, and views trinitarianism as both incomprehensible and a violation of the Bible's teaching that God is one. It rejects the notion that Jesus or any other object or living being could be 'God', that God could have a literal 'son' in physical form or is divisible in any way, or that God could be made to be joined to the material world in such fashion. Although Judaism provides Jews with a word to label God's transcendence (Ein Sof, without end) and immanence (Shekhinah, in-dwelling), these are merely human words to describe two ways of experiencing God; God is one and indivisible. Shituf A minority Jewish view, which appears in some codes of Jewish law, is that while Christian worship is polytheistic (due to the multiplicity of the Trinity), it is permissible for them to swear in God's name, since they are referring to the one God. This theology is referred to in Hebrew as Shituf (literally "partnership" or "association"). Although worship of a trinity is considered to be not different from any other form of idolatry for Jews, it may be an acceptable belief for non-Jews (according to the ruling of some Rabbinic authorities). Right action Faith versus good deeds Judaism teaches that the purpose of the Torah is to teach us how to act correctly. God's existence is a given in Judaism, and not something that most authorities see as a matter of required belief. Although some authorities see the Torah as commanding Jews to believe in God, Jews see belief in God as a necessary, but not sufficient, condition for a Jewish life. The quintessential verbal expression of Judaism is the Shema Yisrael, the statement that the God of the Bible is their God, and that this God is unique and one. The quintessential physical expression of Judaism is behaving in accordance with the 613 Mitzvot (the commandments specified in the Torah), and thus live one's life in God's ways. Thus fundamentally in Judaism, one is enjoined to bring holiness into life (with the guidance of God's laws), rather than removing oneself from life to be holy. Much of Christianity also teaches that God wants people to perform good works, but all branches hold that good works alone will not lead to salvation, which is called Legalism, the exception being dual-covenant theology. Some Christian denominations hold that salvation depends upon transformational faith in Jesus, which expresses itself in good works as a testament (or witness) to ones faith for others to see (primarily Eastern Orthodox Christianity and Roman Catholicism), while others (including most Protestants) hold that faith alone is necessary for salvation. Some argue that the difference is not as great as it seems, because it really hinges on the definition of "faith" used. The first group generally uses the term "faith" to mean "intellectual and heartfelt assent and submission". Such a faith will not be salvific until a person has allowed it to effect a life transforming conversion (turning towards God) in their being (see Ontotheology). The Christians that hold to "salvation by faith alone" (also called by its Latin name "sola fide") define faith as being implicitly ontological—mere intellectual assent is not termed "faith" by these groups. Faith, then, is life-transforming by definition. Sin In both religions, offenses against the will of God are called sin. These sins can be thoughts, words, or deeds. Catholicism categorizes sins into various groups. A wounding of the relationship with God is often called venial sin; a complete rupture of the relationship with God is often called mortal sin. Without salvation from sin (see below), a person's separation from God is permanent, causing such a person to enter Hell in the afterlife. Both the Catholic Church and the Orthodox Church define sin more or less as a "macula", a spiritual stain or uncleanliness that constitutes damage to man's image and likeness of God. Hebrew has several words for sin, each with its own specific meaning. The word pesha, or "trespass", means a sin done out of rebelliousness. The word aveira means "transgression". And the word avone, or "iniquity", means a sin done out of moral failing. The word most commonly translated simply as "sin", het, literally means "to go astray". Just as Jewish law, halakha provides the proper "way" (or path) to live, sin involves straying from that path. Judaism teaches that humans are born with free will, and morally neutral, with both a yetzer hatov, (literally, "the good inclination", in some views, a tendency towards goodness, in others, a tendency towards having a productive life and a tendency to be concerned with others) and a yetzer hara, (literally "the evil inclination", in some views, a tendency towards evil, and in others, a tendency towards base or animal behavior and a tendency to be selfish). In Judaism all human beings are believed to have free will and can choose the path in life that they will take. It does not teach that choosing good is impossible—only at times more difficult. There is almost always a "way back" if a person wills it. (Although texts mention certain categories for whom the way back will be exceedingly hard, such as the slanderer, the habitual gossip, and the malicious person) The rabbis recognize a positive value to the yetzer hara: one tradition identifies it with the observation on the last day of creation that God's accomplishment was "very good" (God's work on the preceding days was just described as "good") and explain that without the yetzer ha'ra there would be no marriage, children, commerce or other fruits of human labor; the implication is that yetzer ha'tov and yetzer ha'ra are best understood not as moral categories of good and evil but as selfless versus selfish orientations, either of which used rightly can serve God's will. In contrast to the Jewish view of being morally balanced, Original Sin refers to the idea that the sin of Adam and Eve's disobedience (sin "at the origin") has passed on a spiritual heritage, so to speak. Christians teach that human beings inherit a corrupted or damaged human nature in which the tendency to do bad is greater than it would have been otherwise, so much so that human nature would not be capable now of participating in the afterlife with God. This is not a matter of being "guilty" of anything; each person is only personally guilty of their own actual sins. However, this understanding of original sin is what lies behind the Christian emphasis on the need for spiritual salvation from a spiritual Saviour, who can forgive and set aside sin even though humans are not inherently pure and worthy of such salvation. Paul the Apostle in Romans and I Corinthians placed special emphasis on this doctrine, and stressed that belief in Jesus would allow Christians to overcome death and attain salvation in the hereafter. Roman Catholics, Eastern Orthodox Christians, and some Protestants teach the Sacrament of Baptism is the means by which each person's damaged human nature is healed and Sanctifying Grace (capacity to enjoy and participate in the spiritual life of God) is restored. This is referred to as "being born of water and the Spirit", following the terminology in the Gospel of St. John. Most Protestants believe this salvific grace comes about at the moment of personal decision to follow Jesus, and that baptism is a symbol of the grace already received. Love The Hebrew word for "love", ahavah (אהבה), is used to describe intimate or romantic feelings or relationships, such as the love between parent and child in Genesis 22:2; 25: 28; 37:3; the love between close friends in I Samuel 18:2, 20:17; or the love between a young man and young woman in Song of Songs. Christians will often use the Greek of the Septuagint to make distinctions between the types of love: philia for brotherly, eros for romantic and agape for self-sacrificing love. Like many Jewish scholars and theologians, literary critic Harold Bloom understands Judaism as fundamentally a religion of love. But he argues that one can understand the Hebrew conception of love only by looking at one of the core commandments of Judaism, Leviticus 19:18, "Love your neighbor as yourself", also called the second Great Commandment. Talmudic sages Hillel and Rabbi Akiva commented that this is a major element of the Jewish religion. Also, this commandment is arguably at the center of the Jewish faith. As the third book of the Torah, Leviticus is literally the central book. Historically, Jews have considered it of central importance: traditionally, children began their study of the Torah with Leviticus, and the midrashic literature on Leviticus is among the longest and most detailed of midrashic literature. Bernard Jacob Bamberger considers Leviticus 19, beginning with God's commandment in verse 3—"You shall be holy, for I the Lord your God, am holy"—to be "the climactic chapter of the book, the one most often read and quoted" (1981:889). Leviticus 19:18 is itself the climax of this chapter. Abortion The only statements in the Tanakh about the status of a fetus state that killing an unborn infant does not have the same status as killing a born human being, and mandates a much lesser penalty. (although this interpretation is disputed, the passage could refer to an injury to a woman that causes a premature, live birth). The Talmud states that the fetus is not yet a full human being until it has been born (either the head or the body is mostly outside of the woman), therefore killing a fetus is not murder, and abortion—in restricted circumstances—has always been legal under Jewish law. Rashi, the great 12th century commentator on the Bible and Talmud, states clearly of the fetus lav nefesh hu: "it is not a person." The Talmud contains the expression ubar yerech imo—the fetus is as the thigh of its mother,' i.e., the fetus is deemed to be part and parcel of the pregnant woman's body." The Babylonian Talmud Yevamot 69b states that: "the embryo is considered to be mere water until the fortieth day." Afterwards, it is considered subhuman until it is born. Christians who agree with these views may refer to this idea as abortion before the quickening of the fetus. Judaism unilaterally supports, in fact mandates, abortion if doctors believe that it is necessary to save the life of the woman. Many rabbinic authorities allow abortions on the grounds of gross genetic imperfections of the fetus. They also allow abortion if the woman were suicidal because of such defects. However, Judaism holds that abortion is impermissible
for wrongs done to others, but rather help in obtaining forgiveness from the other person. Sir Jonathan Sacks, Chief Rabbi of the United Hebrew Congregations of the Commonwealth, summarized: "it is not that God forgives, while human beings do not. To the contrary, we believe that just as only God can forgive sins against God, so only human beings can forgive sins against human beings." Judgment Both Christianity and Judaism believe in some form of judgment. Most Christians (the exception is Full Preterism) believe in the future Second Coming of Jesus, which includes the Resurrection of the Dead and the Last Judgment. Those who have accepted Jesus as their personal saviour will be saved and live in God's presence in the Kingdom of Heaven, those who have not accepted Jesus as their saviour, will be cast into the Lake of fire (eternal torment, finite torment, or simply annihilated), see for example The Sheep and the Goats. In Jewish liturgy there is significant prayer and talk of a "book of life" that one is written into, indicating that God judges each person each year even after death. This annual judgment process begins on Rosh Hashanah and ends with Yom Kippur. Additionally, God sits daily in judgment concerning a person's daily activities. Upon the anticipated arrival of the Messiah, God will judge the nations for their persecution of Israel during the exile. Later, God will also judge the Jews over their observance of the Torah. Heaven and Hell There is little Jewish literature on heaven or hell as actual places, and there are few references to the afterlife in the Hebrew Bible. One is the ghostly apparition of Samuel, called up by the Witch of Endor at King Saul's command. Another is a mention by the Prophet Daniel of those who sleep in the earth rising to either everlasting life or everlasting abhorrence. Early Hebrew views were more concerned with the fate of the nation of Israel as a whole, rather than with individual immortality. A stronger belief in an afterlife for each person developed during the Second Temple period but was contested by various Jewish sects. Pharisees believed that in death, people rest in their graves until they are physically resurrected with the coming of the Messiah, and within that resurrected body the soul would exist eternally. Maimonides also included the concept of resurrection in his Thirteen Principles of Faith. Judaism's view is summed up by a biblical observation about the Torah: in the beginning God clothes the naked (Adam), and at the end God buries the dead (Moses). The Children of Israel mourned for 40 days, then got on with their lives. In Judaism, Heaven is sometimes described as a place where God debates Talmudic law with the angels, and where Jews spend eternity studying the Written and Oral Torah. Jews do not believe in "Hell" as a place of eternal torment. Gehenna is a place or condition of purgatory where Jews spend up to twelve months purifying to get into heaven, depending on how sinful they have been, although some suggest that certain types of sinners can never be purified enough to go to heaven and rather than facing eternal torment, simply cease to exist. Therefore, some violations like suicide would be punished by separation from the community, such as not being buried in a Jewish cemetery (in practice, rabbis often rule suicides to be mentally incompetent and thus not responsible for their actions). Judaism also does not have a notion of hell as a place ruled by Satan since God's dominion is total and Satan is only one of God's angels. Catholics also believe in a purgatory for those who are going to heaven, but Christians in general believe that Hell is a fiery place of torment that never ceases, called the Lake of Fire. A small minority believe this is not permanent, and that those who go there will eventually either be saved or cease to exist. Heaven for Christians is depicted in various ways. As the Kingdom of God described in the New Testament and particularly the Book of Revelation, Heaven is a new or restored earth, a World to Come, free of sin and death, with a New Jerusalem led by God, Jesus, and the most righteous of believers starting with 144,000 Israelites from every tribe, and all others who received salvation living peacefully and making pilgrimages to give glory to the city. In Christianity, promises of Heaven and Hell as rewards and punishments are often used to motivate good and bad behavior, as threats of disaster were used by prophets like Jeremiah to motivate the Israelites. Modern Judaism generally rejects this form of motivation, instead teaching to do the right thing because it's the right thing to do. As Maimonides wrote: "A man should not say: I shall carry out the precepts of the Torah and study her wisdom in order to receive all the blessings written therein or in order to merit the life of the World to Come and I shall keep away from the sins forbidden by the Torah in order to be spared the curses mentioned in the Torah or in order not to be cut off from the life of the World to Come. It is not proper to serve God in this fashion. For one who serves thus serves out of fear. Such a way is not that of the prophets and sages. Only the ignorant, and the women and children serve God in this way. These are trained to serve out of fear until they obtain sufficient knowledge to serve out of love. One who serves God out of love studies the Torah and practices the precepts and walks in the way of wisdom for no ulterior motive at all, neither out of fear of evil nor in order to acquire the good, but follows the truth because it is true and the good will follow the merit of attaining to it. It is the stage of Abraham our father whom the Holy One, blessed be God, called "My friend" (Isaiah 41:8 – ohavi = the one who loves me) because he served out of love alone. It is regarding this stage that the Holy One, Blessed be God, commanded us through Moses, as it is said: "You shall love the Lord your God" (Deuteronomy 6:5). When man loves God with a love that is fitting he automatically carries out all the precepts of love. (Maimonides Yad Chapter 10, quoted in Jacobs 1973: 159) The Messiah Jews believe that a descendant of King David will one day appear to restore the Kingdom of Israel and usher in an era of peace, prosperity, and spiritual understanding for Israel and all the nations of the world. Jews refer to this person as Moshiach or "anointed one", translated as messiah in English. The traditional Jewish understanding of the messiah is that he is fully human and born of human parents without any supernatural element. The messiah is expected to have a relationship with God similar to that of the prophets of the Tanakh. In his commentary on the Talmud, Maimonides (Rabbi Moshe ben Maimon) wrote: All of the people Israel will come back to Torah; The people of Israel will be gathered back to the land of Israel; The Temple in Jerusalem will be rebuilt; Israel will live among the nations as an equal, and will be strong enough to defend herself; Eventually, war, hatred and famine will end, and an era of peace and prosperity will come upon the Earth. He adds: "And if a king shall stand up from among the House of David, studying Torah and indulging in commandments like his father David, according to the written and oral Torah, and he will coerce all Israel to follow it and to strengthen its weak points, and will fight The Lord's wars, this one is to be treated as if he were the anointed one. If he succeeded [and won all nations surrounding him. Old prints and mss.] and built a Holy Temple in its proper place and gathered the strayed ones of Israel together, this is indeed the anointed one for certain, and he will mend the entire world to worship the Lord together ... But if he did not succeed until now, or if he was killed, it becomes known that he is not this one of whom the Torah had promised us, and he is indeed like all [other] proper and wholesome kings of the House of David who died." He also clarified the nature of the Messiah: "Do not imagine that the anointed King must perform miracles and signs and create new things in the world or resurrect the dead and so on. The matter is not so: For Rabbi Akiba was a great scholar of the sages of the Mishnah, and he was the assistant-warrior of the king Ben Coziba Simon bar Kokhba... He and all the Sages of his generation deemed him the anointed king, until he was killed by sins; only since he was killed, they knew that he was not. The Sages asked him neither a miracle nor a sign..." The Christian view of Jesus as Messiah goes beyond such claims and is the fulfillment and union of three anointed offices; a prophet like Moses who delivers God's commands and covenant and frees people from bondage, a High Priest in the order of Melchizedek overshadowing the Levite priesthood and a king like King David ruling over Jews, and like God ruling over the whole world and coming from the line of David. For Christians, Jesus is also fully human and fully divine as the Word of God who sacrifices himself so that humans can receive salvation. Jesus sits in Heaven at the Right Hand of God and will judge humanity in the end times when he returns to earth. Christian readings of the Hebrew Bible find many references to Jesus. This can take the form of specific prophesy, and in other cases of foreshadowing by types or forerunners. Traditionally, most Christian readings of the Bible maintained that almost every prophecy was actually about the coming of Jesus, and that the entire Old Testament of the Bible is a prophecy about the coming of Jesus. Catholic views Catholicism teaches Extra Ecclesiam Nulla Salus ("Outside the Church there is no salvation"), which some, like Fr. Leonard Feeney, interpreted as limiting salvation to Catholics only. At the same time, it does not deny the possibility that those not visibly members of the Church may attain salvation as well. In recent times, its teaching has been most notably expressed in the Vatican II council documents Unitatis Redintegratio (1964), Lumen gentium (1964), Nostra aetate (1965), an encyclical issued by Pope John Paul II: Ut unum sint (1995), and in a document issued by the Congregation for the Doctrine of the Faith, Dominus Iesus in 2000. The latter document has been criticised for claiming that non-Christians are in a "gravely deficient situation" as compared to Catholics, but also adds that "for those who are not formally and visibly members of the Church, salvation in Christ is accessible by virtue of a grace which, while having a mysterious relationship to the Church, does not make them formally part of the Church, but enlightens them in a way which is accommodated to their spiritual and material situation." Pope John Paul II on 2 October 2000 emphasized that this document did not say that non-Christians were actively denied salvation: "...this confession does not deny salvation to non-Christians, but points to its ultimate source in Christ, in whom man and God are united". On 6 December the Pope issued a statement to further emphasize that the Church continued to support its traditional stance that salvation was available to believers of other faiths: "The gospel teaches us that those who live in accordance with the Beatitudes—the poor in spirit, the pure of heart, those who bear lovingly the sufferings of life—will enter God's kingdom." He further added, "All who seek God with a sincere heart, including those who do not know Christ and his church, contribute under the influence of Grace to the building of this Kingdom." On 13 August 2002 American Catholic bishops issued a joint statement with leaders of Reform and Conservative Judaism, called "Reflections on Covenant and Mission", which affirmed that Christians should not target Jews for conversion. The document stated: "Jews already dwell in a saving covenant with God" and "Jews are also called by God to prepare the world for God's Kingdom." However, many Christian denominations still believe it is their duty to reach out to "unbelieving" Jews. In December 2015, the Vatican released a 10,000-word document that, among other things, stated that Jews do not need to be converted to find salvation, and that Catholics should work with Jews to fight antisemitism. Eastern Orthodox views Eastern Orthodox Christianity emphasizes a continuing life of repentance or metanoia, which includes an increasing improvement in thought, belief and action. Regarding the salvation of Jews, Muslims, and other non-Christians, the Orthodox have traditionally taught that there is no salvation outside the church. Orthodoxy recognizes that other religions may contain truth, to the extent that they are in agreement with Christianity. God is thought to be good, just, and merciful; it would not seem just to condemn someone because they never heard the Gospel message, or were taught a distorted version of the Gospel by heretics. Therefore, the reasoning goes, they must at some point have an opportunity to make a genuine informed decision. Ultimately, those who persist in rejecting God condemn themselves, by cutting themselves off from the ultimate source of all Life, and from the God who is Love embodied. Jews, Muslims, and members of other faiths, then, are expected to convert to Christianity in the afterlife. Proselytizing Judaism is not a proselytizing religion. Orthodox Judaism deliberately makes it very difficult to convert and become a Jew, and requires a significant and full-time effort in living, study, righteousness, and conduct over several years. The final decision is by no means a foregone conclusion. A person cannot become Jewish by marrying a Jew, or by joining a synagogue, nor by any degree of involvement in the community or religion, but only by explicitly undertaking intense, formal, and supervised work over years aimed towards that goal. Some less strict versions of Judaism have made this process somewhat easier but it is still far from common. In the past, scholars understood Judaism to have an evangelistic drive, but today's scholars are inclined to the view that it was often more akin just to "greater openness to converts" rather than active soliciting of conversions. Since Jews believe that one need not be a Jew to approach God, there is no religious pressure to convert non-Jews to their faith. Indeed, Scholars have revisited the traditional claims about Jewish proselytizing and have brought forward a variety of new insights. McKnight and Goodman have argued persuasively that a distinction ought to be made between the passive reception of converts or interested Pagans, and an active desire or intent to convert the non-Jewish world to Judaism. The Chabad-Lubavitch branch of Hasidic Judaism has been an exception to this non-proselytizing standard, since in recent decades it has been actively promoting Noahide Laws for gentiles as an alternative to Christianity. By contrast, Christianity is an explicitly evangelistic religion. Christians are commanded by Jesus to "Therefore go and make disciples of all nations". Historically, evangelism has on rare occasions led to forced conversion under threat of death or mass expulsion. Mutual views Common Jewish views of Christianity Many Jews view Jesus as one in a long list of failed Jewish claimants to be the Messiah, none of whom fulfilled the tests of a prophet specified in the Law of Moses. Others see Jesus as a teacher who worked with the gentiles and ascribe the messianic claims that Jews find objectionable to his later followers. Because much physical and spiritual violence was done to Jews in the name of Jesus and his followers, and because evangelism is still an active aspect of many church's activities, many Jews are uncomfortable with discussing Jesus and treat him as a non-person. In answering the question "What do Jews think of Jesus", philosopher Milton Steinberg claims, for Jews, Jesus cannot be accepted as anything more than a teacher. "In only a few respects did Jesus deviate from the Tradition," Steinberg concludes, "and in all of them, Jews believe, he blundered." Judaism does not believe that God requires the sacrifice of any human. This is emphasized in Jewish traditions concerning the story of the Akedah, the binding of Isaac. In the Jewish explanation, this is a story in the Torah whereby God wanted to test Abraham's faith and willingness, and Isaac was never going to be actually sacrificed. Thus, Judaism rejects the notion that anyone can or should die for anyone else's sin. Judaism is more focused on the practicalities of understanding how one may live a sacred life in the world according to God's will, rather than a hope of a future one. Judaism does not believe in the Christian concept of hell but does have a punishment stage in the afterlife (i.e. Gehenna, a term that also appears in the New Testament and translated as hell) as well as a Heaven (Gan Eden), but the religion does not intend it as a focus. Judaism views the worship of Jesus as inherently polytheistic, and rejects the Christian attempts to explain the Trinity as a complex monotheism. Christian festivals have no religious significance in Judaism and are not celebrated, but some secular Jews in the West treat Christmas as a secular holiday. Common Christian views of Judaism Christians believe that Christianity is the fulfillment and successor of Judaism, retaining much of its doctrine and many of its practices including monotheism, the belief in a Messiah, and certain forms of worship like prayer and reading from religious texts. Christians believe that Judaism requires blood sacrifice to atone for sins, and believe that Judaism has abandoned this since the destruction of the Second Temple. Most Christians consider the Mosaic Law to have been a necessary intermediate stage, but that once the crucifixion of Jesus occurred, adherence to civil and ceremonial Law was superseded by the New Covenant. Some Christians adhere to New Covenant theology, which states that with the arrival of his New Covenant, Jews have ceased being blessed under his Mosaic covenant. This position has been softened or disputed by other Christians, where Jews are recognized to have a special status under the Abrahamic covenant. New Covenant theology is thus in contrast to Dual-covenant theology. Some Christians who view the Jewish people as close to God seek to understand and incorporate elements of Jewish understanding or perspective into their beliefs as a means to respect their "parent" religion of Judaism, or to more fully seek out and return to their Christian roots.

of the papal armies with a number of Italian mercenaries, supported by 300 cavalry and 4,000 Swiss infantry sent by the King of France. Alexander sent him to capture Imola and Forlì, ruled by Caterina Sforza (mother of the Medici condottiero Giovanni dalle Bande Nere). Despite being deprived of his French troops after the conquest of those two cities, Borgia returned to Rome to celebrate a triumph and to receive the title of Papal Gonfalonier from his father. In 1500 the creation of twelve new cardinals granted Alexander enough money for Cesare to hire the condottieri, Vitellozzo Vitelli, Gian Paolo Baglioni, Giulio and Paolo Orsini, and Oliverotto Euffreducci, who resumed his campaign in Romagna. Giovanni Sforza, first husband of Cesare's sister Lucrezia, was soon ousted from Pesaro; Pandolfo Malatesta lost Rimini; Faenza surrendered, its young lord Astorre III Manfredi being later drowned in the Tiber by Cesare's order. In May 1501 the latter was created duke of Romagna. Hired by Florence, Cesare subsequently added the lordship of Piombino to his new lands. While his condottieri took over the siege of Piombino which ended in 1502, Cesare commanded the French troops in the sieges of Naples and Capua, defended by Prospero and Fabrizio Colonna. On 24 June 1501 his troops stormed the latter, causing the collapse of Aragonese power in southern Italy. In June 1502 he set out for Marche, where he was able to capture Urbino and Camerino by treason. He planned to conquer Bologna next. However, his condottieri, most notably Vitellozzo Vitelli and the Orsini brothers (Giulio, Paolo and Francesco), feared Cesare's cruelty and set up a plot against him. Guidobaldo da Montefeltro and Giovanni Maria da Varano returned to Urbino and Camerino, and Fossombrone revolted. The fact that his subjects had enjoyed his rule thus far meant that his opponents had to work much harder than they would have liked. He eventually recalled his loyal generals to Imola, where he waited for his opponents' loose alliance to collapse. Cesare called for a reconciliation, but imprisoned his condottieri in Senigallia, then called Sinigaglia, a feat described as a "wonderful deceiving" by historian Paolo Giovio, and had them strangled. In 1503 he conquered the Republic of San Marino. Later years and death Although he was an immensely capable general and statesman, Cesare had trouble maintaining his domain without continued Papal patronage. Niccolò Machiavelli cites Cesare's dependence on the good will of the Papacy, under the control of his father, as being the principal disadvantage of his rule. Machiavelli argued that, had Cesare been able to win the favour of the new Pope, he would have been a very successful ruler. The news of his father's death in 1503 arrived when Cesare was planning the conquest of Tuscany. While he was convalescing in Castel Sant'Angelo from an attack of malarial fever (likely contracted on the same occasion when Alexander contracted his fatal illness), his troops controlled the conclave. The new pope, Pope Pius III, supported Cesare Borgia and reconfirmed him as Gonfaloniere, but after a brief pontificate of twenty-six days, he died. Borgia's deadly enemy, Giuliano Della Rovere, then succeeded by dexterous diplomacy in tricking the weakened Cesare Borgia into supporting him by offering him money and continued papal backing for Borgia policies in the Romagna; promises which he disregarded upon his election as Pope Julius II by the near-unanimous vote of the cardinals. Realizing his mistake by then, Cesare tried to correct the situation to his favour, but Pope Julius II made sure of its failure at every turn. Cesare was for example forced by Julius to give up San Marino, after occupying the republic for six months. Cesare Borgia, who was facing the hostility of Ferdinand II of Aragon, was betrayed while in Naples by Gonzalo Fernández de Córdoba, a man he had considered his ally, and imprisoned there, while his lands were retaken by the Papacy. In 1504 he was transferred to Spain and imprisoned first in the Castle of Chinchilla de Montearagón in La Mancha, but after an attempted escape he was moved north to the Castle of La Mota, Medina del Campo, near Segovia. He did manage to escape from the Castle of La Mota with assistance, and after running across Santander, Durango and Gipuzkoa, he arrived in Pamplona on 3 December 1506, and was much welcomed by King John III of Navarre, who was missing an experienced military commander, ahead of the feared Castilian invasion. Borgia recaptured Viana, Navarre, then in the hands of forces loyal to Louis de Beaumont, the count of Lerín and Ferdinand II of Aragon's conspiratorial ally in Navarre, but not the castle, which he then besieged. In the early morning of 11 March 1507, an enemy party of knights fled from the castle during a heavy storm. Outraged at the ineffectiveness of the siege, Borgia chased them, only to find himself on his own. The party of knights, discovering that he was alone, trapped him in an ambush, where he received a fatal injury from a spear. He was then stripped of all his luxurious garments, valuables, and a leather mask covering half his face (disfigured, possibly by syphilis, during his late years). Borgia was left lying naked, with just a red tile covering his genitals. Remains Borgia was originally buried in a marbled mausoleum King John III had ordered built at the altar of the Church of Santa María in Viana in Navarre in northern Spain, set on one of the stops on the Camino de Santiago. In the 16th century the Bishop of Mondoñedo, Antonio de Guevara, published from memory what he had seen written on the tomb when he had paid a visit to the church. This epitaph underwent several changes in wording and meter throughout the years and the version most commonly cited today is that published by the priest and historian Francisco de Alesón in the 18th century. It reads: Borgia was an old enemy
the nominal husband of Vannozza dei Cattanei. More likely, Pope Sixtus IV granted Cesare a release from the necessity of proving his birth in a papal bull of 1 October 1480. Career Church office Cesare was initially groomed for a career in the Church. Following school in Perugia and Pisa, Cesare studied law at the Studium Urbis (nowadays Sapienza University of Rome). He was made Bishop of Pamplona at the age of 15 and archbishop of Valencia at 17. In 1493, he had also been appointed bishop of both Castres and Elne. In 1494, he also received the title of abbot of the abbey of Saint-Michel-de-Cuxa. Along with his father's elevation to Pope, Cesare was made Cardinal at the age of 18. Alexander VI staked the hopes of the Borgia family on Cesare's brother Giovanni, who was made captain general of the military forces of the papacy. Giovanni was assassinated in 1497 under mysterious circumstances. Several contemporaries suggested that Cesare might have been his killer, as Giovanni's disappearance could finally open to him a long-awaited military career and also solve the jealousy over Sancha of Aragon, wife of Cesare's younger brother, Gioffre, and mistress of both Cesare and Giovanni. Cesare's role in the act has never been clear. However, he had no definitive motive, as he was likely to be given a powerful secular position, whether or not his brother lived. It is possible that Giovanni was killed as a result of a sexual liaison. On 17 August 1498, Cesare became the first person in history to resign the cardinalate, which he did in order to pursue a military career. On the same day, Louis XII of France named Cesare Duke of Valentinois. This title, along with his former position as Cardinal of Valencia, explains the nickname "Valentino". Military Cesare's career was founded upon his father's ability to distribute patronage, along with his alliance with France (reinforced by his marriage with Charlotte d'Albret, sister of John III of Navarre), in the course of the Italian Wars. Louis XII invaded Italy in 1499; after Gian Giacomo Trivulzio had ousted its duke Ludovico Sforza, Cesare accompanied the king in his entrance into Milan. At this point, Alexander decided to profit from the favourable situation and carve out for Cesare a state of his own in northern Italy. To this end, he declared that all his vicars in Romagna and Marche were deposed. Though in theory subject directly to the pope, these rulers had been practically independent or dependent on other states for generations. In the view of the citizens, these vicars were cruel and petty. When Cesare eventually took power, he was viewed by the citizens as a great improvement. Cesare was appointed commander of the papal armies with a number of Italian mercenaries, supported by 300 cavalry and 4,000 Swiss infantry sent by the King of France. Alexander sent him to capture Imola and Forlì, ruled by Caterina Sforza (mother of the Medici condottiero Giovanni dalle Bande Nere).

Determining the reliability of particular chronicles is important to historians. Many newspapers and other periodical literature have adopted "chronicle" as part of their name. Various fictional stories have also adopted "chronicle" as part of their title, to give an impression of epic proportion to their stories. Subgroups Scholars categorize the genre of chronicle into two subgroups: live chronicles, and dead chronicles. A dead chronicle is one where the author assembles a list of events up to the time of their writing, but does not record further events as they occur. A live chronicle is where one or more authors add to a chronicle in a regular fashion, recording contemporary events shortly after they occur. Because of the immediacy of the information, historians tend to value live chronicles, such as annals, over dead ones. The term often refers to a book written by a chronicler in the Middle Ages describing historical events in a country, or the lives of a nobleman or a clergyman, although it is also applied to a record of public events. The earliest medieval chronicle to combine both retrospective (dead) and contemporary (live) entries, is the Chronicle of Ireland, which spans the years 431 to 911. Chronicles are the predecessors of modern "time lines" rather than analytical histories. They represent accounts, in prose or verse, of local or distant events over a considerable period of time, both the lifetime of the individual chronicler and often those of several subsequent continuators. If the chronicles deal with events year by year, they are often called annals. Unlike the modern historian, most chroniclers tended to take their information as they found it, and made little attempt to separate fact from legend. The point of view of most chroniclers is highly localised, to the extent that many anonymous chroniclers can be sited in individual abbeys. It is impossible to say how many chronicles exist, as the many ambiguities in the definition of the genre make it impossible to draw clear distinctions of what should or should not be included. However, the Encyclopedia of the Medieval Chronicle lists some 2,500 items written between 300 and 1500 AD. Citation of entries Entries in chronicles are often cited using the abbreviation s.a., meaning sub anno (under the year), according to the year under which they are listed. For example, "ASC MS A, s.a. 855" means the entry for the year 855 in manuscript A of the Anglo-Saxon Chronicle. The same event may be recorded under a different year in another manuscript of the chronicle, and may be cited for example as "ASC MS D, s.a. 857". English chronicles The most important English chronicles are the Anglo-Saxon Chronicle, started under the patronage of King Alfred in the 9th century and continued until the 12th century, and the Chronicles of England, Scotland and Ireland (1577–87) by Raphael Holinshed and other writers; the latter documents were important sources of materials for Elizabethan drama.

by the volume of the mixture : The SI unit is mol/m3. However, more commonly the unit mol/L (= mol/dm3) is used. Number concentration The number concentration is defined as the number of entities of a constituent in a mixture divided by the volume of the mixture : The SI unit is 1/m3. Volume concentration The volume concentration (not to be confused with volume fraction) is defined as the volume of a constituent divided by the volume of the mixture : Being dimensionless, it is expressed as a number, e.g., 0.18 or 18%; its unit is 1. There seems to be no standard notation in the English literature. The letter used here is normative in German literature (see Volumenkonzentration). Related quantities Several other quantities can be used to describe the composition of a mixture. Note that these should not be called concentrations. Normality Normality is defined as the molar concentration divided by an equivalence factor . Since the definition of the equivalence factor depends on context (which reaction is being studied), IUPAC and NIST discourage the use of normality. Molality (Not to be confused with Molarity) The molality of a solution is defined as the amount of a constituent (in moles) divided by the mass of the solvent (not the mass of the solution): The SI unit for molality is mol/kg. Mole fraction The mole fraction is defined as the amount of a constituent (in moles) divided by the total amount of all constituents in a mixture : The SI unit is mol/mol. However, the deprecated parts-per notation is often used to describe small mole fractions. Mole ratio The mole ratio is defined as the amount
at the center”. Qualitative description Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" for solutions of relatively low concentration and "concentrated" for solutions of relatively high concentration. To concentrate a solution, one must add more solute (for example, alcohol), or reduce the amount of solvent (for example, water). By contrast, to dilute a solution, one must add more solvent, or reduce the amount of solute. Unless two substances are miscible, there exists a concentration at which no further solute will dissolve in a solution. At this point, the solution is said to be saturated. If additional solute is added to a saturated solution, it will not dissolve, except in certain circumstances, when supersaturation may occur. Instead, phase separation will occur, leading to coexisting phases, either completely separated or mixed as a suspension. The point of saturation depends on many variables such as ambient temperature and the precise chemical nature of the solvent and solute. Concentrations are often called levels, reflecting the mental schema of levels on the vertical axis of a graph, which can be high or low (for example, "high serum levels of bilirubin" are concentrations of bilirubin in the blood serum that are greater than normal). Quantitative notation There are four quantities that describe concentration: Mass concentration The mass concentration is defined as the mass of a constituent divided by the volume of the mixture : The SI unit is kg/m3 (equal to g/L). Molar concentration The molar concentration is defined as the amount of a constituent (in moles) divided by the volume of the mixture : The SI unit is mol/m3. However, more commonly the unit mol/L (= mol/dm3) is used. Number concentration The number concentration is defined as the number of entities of a constituent in a mixture divided by the volume of the mixture : The SI unit is 1/m3. Volume concentration The volume concentration (not to be confused with volume fraction) is defined as the volume of a constituent divided by the volume of the mixture : Being dimensionless, it is expressed as a number, e.g., 0.18 or 18%;

with military curfews and the 1980 Turkish coup d'état on September 12, 1980. General Kenan Evren took over the government and temporarily banned all the nation's political parties. After the coup, many intellectuals, including writers, artists and journalists, were arrested. A warrant was issued for the arrest of Karaca by the government of Turkey. The state invited Karaca back several times, but Karaca, not knowing what would happen upon his return, decided not to come back. While Karaca was in Germany his father died, but he could not return to attend the funeral. After some time, the Turkish government decided to strip Cem Karaca of his Turkish citizenship, keeping the arrest warrant active. Several years later, in 1987, the prime minister and leader of the Turkish Motherland Party, Turgut Özal, issued an amnesty for Karaca. Shortly afterwards, he returned to Turkey. His return also brought a new album with it, Merhaba Gençler ve Her Zaman Genç Kalanlar ("Hello, The Young and The Young at Heart"), one of his most influential works. His return home was received cheerfully by his fans, but during his absence Karaca had lost the young audience and acquired only a few new listeners. He died of a heart attack on February 8, 2004 and was interred at Karacaahmet Cemetery in the Üsküdar district of Istanbul.

New York (1993) and Getting In (1994), her first substantial speaking part in a film was in Quiz Show, directed by Robert Redford. Flockhart debuted on Broadway in 1994, as Laura in The Glass Menagerie. Actress Julie Harris felt Flockhart should be hired without further auditions, claiming that she seemed ideal for the part. Flockhart received a Clarence Derwent Award for her performance. In 1995, Flockhart became acquainted with actors such as Dianne Wiest and Faye Dunaway when she appeared in the movie Drunks. In 1996, Flockhart appeared as the daughter of Dianne Wiest and Gene Hackman's characters in The Birdcage. Later that year, Flockhart starred in Jane Doe as a drug addict, though it was not released until 1999 over three years after filming. Throughout that year, she continued to work on Broadway, playing the role of Natasha in Anton Chekhov's Three Sisters. Ally McBeal In 1997, Flockhart was asked to audition for the starring role in David E. Kelley's Fox television series Ally McBeal. Kelley, having heard of Flockhart, wanted her to audition for the contract part. Though she initially hesitated due to the necessary commitment to the show in a negotiable contract, she was swayed by the script and traveled to Los Angeles to audition for the part, which she won. She earned a Golden Globe Award for the role in 1998. Flockhart also appeared on the June 29, 1998, cover of Time magazine, placed as the newest iteration in the evolution of feminism, relating to the ongoing debate about the role depicted by her character. Flockhart starred on the show until it was canceled in 2002. Brothers & Sisters Flockhart performed in a starring role as Kitty Walker, opposite Sally Field, Rachel Griffiths and Matthew Rhys, in the ABC critically acclaimed prime time series Brothers & Sisters, which premiered in September 2006 in the time slot after Desperate Housewives. The show was cancelled in May 2011 after running for five years. Flockhart's character was significant throughout the series' first four years, but her appearances were
venue usually is reserved for juniors and seniors, Harold Scott insisted that Flockhart perform there in his production of William Inge's Picnic. Flockhart graduated with a Bachelor of Fine Arts in theater in 1988 from Rutgers University–New Brunswick as one of the few students who successfully completed the acting course. Rutgers inducted her into the Hall of Distinguished Alumni on May 3, 2003. Career Early career In spring 1989, Flockhart made her first television appearance in a minor role in an episode of Guiding Light as a babysitter. Also, she played a teenager battling an eating disorder on a one-hour afternoon special on TV. Flockhart made her professional debut on the New York stage, appearing in Beside Herself alongside Melissa Joan Hart, at the Circle Repertory Theatre. Two years later, Flockhart appeared in the television movie Darrow. Though she later appeared in films Naked in New York (1993) and Getting In (1994), her first substantial speaking part in a film was in Quiz Show, directed by Robert Redford.

1 ≤ p < ∞ is the convolution with a tempered distribution whose Fourier transform is bounded. To wit, they are all given by bounded Fourier multipliers. Convolutions on groups If G is a suitable group endowed with a measure λ, and if f and g are real or complex valued integrable functions on G, then we can define their convolution by It is not commutative in general. In typical cases of interest G is a locally compact Hausdorff topological group and λ is a (left-) Haar measure. In that case, unless G is unimodular, the convolution defined in this way is not the same as . The preference of one over the other is made so that convolution with a fixed function g commutes with left translation in the group: Furthermore, the convention is also required for consistency with the definition of the convolution of measures given below. However, with a right instead of a left Haar measure, the latter integral is preferred over the former. On locally compact abelian groups, a version of the convolution theorem holds: the Fourier transform of a convolution is the pointwise product of the Fourier transforms. The circle group T with the Lebesgue measure is an immediate example. For a fixed g in L1(T), we have the following familiar operator acting on the Hilbert space L2(T): The operator T is compact. A direct calculation shows that its adjoint T* is convolution with By the commutativity property cited above, T is normal: T* T = TT* . Also, T commutes with the translation operators. Consider the family S of operators consisting of all such convolutions and the translation operators. Then S is a commuting family of normal operators. According to spectral theory, there exists an orthonormal basis {hk} that simultaneously diagonalizes S. This characterizes convolutions on the circle. Specifically, we have which are precisely the characters of T. Each convolution is a compact multiplication operator in this basis. This can be viewed as a version of the convolution theorem discussed above. A discrete example is a finite cyclic group of order n. Convolution operators are here represented by circulant matrices, and can be diagonalized by the discrete Fourier transform. A similar result holds for compact groups (not necessarily abelian): the matrix coefficients of finite-dimensional unitary representations form an orthonormal basis in L2 by the Peter–Weyl theorem, and an analog of the convolution theorem continues to hold, along with many other aspects of harmonic analysis that depend on the Fourier transform. Convolution of measures Let G be a (multiplicatively written) topological group. If μ and ν are finite Borel measures on G, then their convolution μ∗ν is defined as the pushforward measure of the group action and can be written as : for each measurable subset E of G. The convolution is also a finite measure, whose total variation satisfies In the case when G is locally compact with (left-)Haar measure λ, and μ and ν are absolutely continuous with respect to a λ, so that each has a density function, then the convolution μ∗ν is also absolutely continuous, and its density function is just the convolution of the two separate density functions. If μ and ν are probability measures on the topological group then the convolution μ∗ν is the probability distribution of the sum X + Y of two independent random variables X and Y whose respective distributions are μ and ν. Bialgebras Let (X, Δ, ∇, ε, η) be a bialgebra with comultiplication Δ, multiplication ∇, unit η, and counit ε. The convolution is a product defined on the endomorphism algebra End(X) as follows. Let φ, ψ ∈ End(X), that is, φ, ψ: X → X are functions that respect all algebraic structure of X, then the convolution φ∗ψ is defined as the composition The convolution appears notably in the definition of Hopf algebras . A bialgebra is a Hopf algebra if and only if it has an antipode: an endomorphism S such that Applications Convolution and related operations are found in many applications in science, engineering and mathematics. In image processing In digital image processing convolutional filtering plays an important role in many important algorithms in edge detection and related processes. In optics, an out-of-focus photograph is a convolution of the sharp image with a lens function. The photographic term for this is bokeh. In image processing applications such as adding blurring. In digital data processing In analytical chemistry, Savitzky–Golay smoothing filters are used for the analysis of spectroscopic data. They can improve signal-to-noise ratio with minimal distortion of the spectra In statistics, a weighted moving average is a convolution. In acoustics, reverberation is the convolution of the original sound with echoes from objects surrounding the sound source. In digital signal processing, convolution is used to map the impulse response of a real room on a digital audio signal. In electronic music convolution is the imposition of a spectral or rhythmic structure on a sound. Often this envelope or structure is taken from another sound. The convolution of two signals is the filtering of one through the other. In electrical engineering, the convolution of one function (the input signal) with a second function (the impulse response) gives the output of a linear time-invariant system (LTI). At any given moment, the output is an accumulated effect of all the prior values of the input function, with the most recent values typically having the most influence (expressed as a multiplicative factor). The impulse response function provides that factor as a function of the elapsed time since each input value occurred. In physics, wherever there is a linear system with a "superposition principle", a convolution operation makes an appearance. For instance, in spectroscopy line broadening due to the Doppler effect on its own gives a Gaussian spectral line shape and collision broadening alone gives a Lorentzian line shape. When both effects are operative, the line shape is a convolution of Gaussian and Lorentzian, a Voigt function. In time-resolved fluorescence spectroscopy, the excitation signal can be treated as a chain of delta pulses, and the measured fluorescence is a sum of exponential decays from each delta pulse. In computational fluid dynamics, the large eddy simulation (LES) turbulence model uses the convolution operation to lower the range of length scales necessary in computation thereby reducing computational cost. In probability theory, the probability distribution of the sum of two independent random variables is the convolution of their individual distributions. In kernel density estimation, a distribution is estimated from sample points by convolution with a kernel, such as an isotropic Gaussian. In radiotherapy treatment planning systems, most part of all modern codes of calculation applies
The existing ones are only modified (amplitude and/or phase). In other words, the output transform is the pointwise product of the input transform with a third transform (known as a transfer function). See Convolution theorem for a derivation of that property of convolution. Conversely, convolution can be derived as the inverse Fourier transform of the pointwise product of two Fourier transforms. Visual explanation Historical developments One of the earliest uses of the convolution integral appeared in D'Alembert's derivation of Taylor's theorem in Recherches sur différents points importants du système du monde, published in 1754. Also, an expression of the type: is used by Sylvestre François Lacroix on page 505 of his book entitled Treatise on differences and series, which is the last of 3 volumes of the encyclopedic series: Traité du calcul différentiel et du calcul intégral, Chez Courcier, Paris, 1797–1800. Soon thereafter, convolution operations appear in the works of Pierre Simon Laplace, Jean-Baptiste Joseph Fourier, Siméon Denis Poisson, and others. The term itself did not come into wide use until the 1950s or 60s. Prior to that it was sometimes known as Faltung (which means folding in German), composition product, superposition integral, and Carson's integral. Yet it appears as early as 1903, though the definition is rather unfamiliar in older uses. The operation: is a particular case of composition products considered by the Italian mathematician Vito Volterra in 1913. Circular convolution When a function is periodic, with period , then for functions, , such that exists, the convolution is also periodic and identical to: where is an arbitrary choice. The summation is called a periodic summation of the function . When is a periodic summation of another function, , then is known as a circular or cyclic convolution of and . And if the periodic summation above is replaced by , the operation is called a periodic convolution of and . Discrete convolution For complex-valued functions defined on the set Z of integers, the discrete convolution of and is given by: or equivalently (see commutativity) by: The convolution of two finite sequences is defined by extending the sequences to finitely supported functions on the set of integers. When the sequences are the coefficients of two polynomials, then the coefficients of the ordinary product of the two polynomials are the convolution of the original two sequences. This is known as the Cauchy product of the coefficients of the sequences. Thus when has finite support in the set (representing, for instance, a finite impulse response), a finite summation may be used: Circular discrete convolution When a function is periodic, with period , then for functions, , such that exists, the convolution is also periodic and identical to: The summation on is called a periodic summation of the function . If is a periodic summation of another function, , then is known as a circular convolution of and . When the non-zero durations of both and are limited to the interval , reduces to these common forms: The notation () for cyclic convolution denotes convolution over the cyclic group of integers modulo . Circular convolution arises most often in the context of fast convolution with a fast Fourier transform (FFT) algorithm. Fast convolution algorithms In many situations, discrete convolutions can be converted to circular convolutions so that fast transforms with a convolution property can be used to implement the computation. For example, convolution of digit sequences is the kernel operation in multiplication of multi-digit numbers, which can therefore be efficiently implemented with transform techniques (; ). requires arithmetic operations per output value and operations for outputs. That can be significantly reduced with any of several fast algorithms. Digital signal processing and other applications typically use fast convolution algorithms to reduce the cost of the convolution to O( log ) complexity. The most common fast convolution algorithms use fast Fourier transform (FFT) algorithms via the circular convolution theorem. Specifically, the circular convolution of two finite-length sequences is found by taking an FFT of each sequence, multiplying pointwise, and then performing an inverse FFT. Convolutions of the type defined above are then efficiently implemented using that technique in conjunction with zero-extension and/or discarding portions of the output. Other fast convolution algorithms, such as the Schönhage–Strassen algorithm or the Mersenne transform, use fast Fourier transforms in other rings. If one sequence is much longer than the other, zero-extension of the shorter sequence and fast circular convolution is not the most computationally efficient method available. Instead, decomposing the longer sequence into blocks and convolving each block allows for faster algorithms such as the overlap–save method and overlap–add method. A hybrid convolution method that combines block and FIR algorithms allows for a zero input-output latency that is useful for real-time convolution computations. Domain of definition The convolution of two complex-valued functions on is itself a complex-valued function on , defined by: and is well-defined only if and decay sufficiently rapidly at infinity in order for the integral to exist. Conditions for the existence of the convolution may be tricky, since a blow-up in at infinity can be easily offset by sufficiently rapid decay in . The question of existence thus may involve different conditions on and : Compactly supported functions If and are compactly supported continuous functions, then their convolution exists, and is also compactly supported and continuous . More generally, if either function (say ) is compactly supported and the other is locally integrable, then the convolution is well-defined and continuous. Convolution of and is also well defined when both functions are locally square integrable on and supported on an interval of the form (or both supported on ). Integrable functions The convolution of and exists if and are both Lebesgue integrable functions in (), and in this case is also integrable . This is a consequence of Tonelli's theorem. This is also true for functions in , under the discrete convolution, or more generally for the convolution on any group. Likewise, if () and () where , then (), and In the particular case , this shows that is a Banach algebra under the convolution (and equality of the two sides holds if and are non-negative almost everywhere). More generally, Young's inequality implies that the convolution is a continuous bilinear map between suitable spaces. Specifically, if satisfy: then so that the convolution is a continuous bilinear mapping from to . The Young inequality for convolution is also true in other contexts (circle group, convolution on ). The preceding inequality is not sharp on the real line: when , there exists a constant such that: The optimal value of was discovered in 1975 and independently in 1976, see Brascamp–Lieb inequality. A stronger estimate is true provided : where is the weak norm. Convolution also defines a bilinear continuous map for , owing to the weak Young inequality: Functions of rapid decay In addition to compactly supported functions and integrable functions, functions that have sufficiently rapid decay at infinity can also be convolved. An important feature of the convolution is that if f and g both decay rapidly, then f∗g also decays rapidly. In particular, if f and g are rapidly decreasing functions, then so is the convolution f∗g. Combined with the fact that convolution commutes with differentiation (see #Properties), it follows that the class of Schwartz functions is closed under convolution . Distributions Under some circumstances, it is possible to define the convolution of a function with a distribution, or of two distributions. If f is a compactly supported function and g is a distribution, then f∗g is a smooth function defined by a distributional formula analogous to More generally, it is possible to extend the definition of the convolution in a unique way so that the associative law remains valid in the case where f is a distribution, and g a compactly supported distribution . Measures The convolution of any two Borel measures μ and ν of bounded variation is the measure defined by In particular, where is a measurable set and is the indicator function of . This agrees with the convolution defined above when μ and ν are regarded as distributions, as well as the convolution of L1 functions when μ and ν are absolutely continuous with respect to the Lebesgue measure. The convolution of measures also satisfies the following version of Young's inequality where the norm is the total variation of a measure. Because the space of measures of bounded variation is a Banach space, convolution of measures can be treated with standard methods of functional analysis that may not apply for the convolution of distributions. Properties Algebraic properties The convolution defines a product on the linear space of integrable functions. This product satisfies the following algebraic properties, which formally mean that the space of integrable functions with the product given by convolution is a commutative associative algebra without identity . Other linear spaces of functions, such as the space of continuous functions of compact support, are closed under the convolution, and so also form commutative associative algebras. Commutativity Proof: By definition: Changing the variable of integration to the result follows. Associativity Proof: This follows from using Fubini's theorem (i.e., double integrals can be evaluated as iterated integrals in either order). Distributivity Proof: This follows from linearity of the integral. Associativity with scalar multiplication for any real (or complex) number . Multiplicative identity No algebra of functions possesses an identity for the convolution. The lack of identity is typically not a major inconvenience, since most collections of functions on which the convolution is performed can be convolved with a delta distribution (a unitary impulse, centered at zero) or, at the very least (as is the case of L1) admit approximations to the identity. The linear space of compactly supported distributions does, however, admit an identity under the convolution. Specifically, where δ is the delta distribution. Inverse element Some distributions S have an inverse element S−1 for the convolution which then must satisfy from which an explicit formula for S−1 may be obtained.The set of invertible distributions forms an abelian group under the convolution. Complex conjugation Relationship with differentiation Proof: Relationship with integration If and then Integration If f and g are integrable functions, then the integral of their convolution on the whole space is simply obtained as the product of their integrals: This follows from Fubini's theorem. The same result holds if f and g are only assumed to be nonnegative measurable functions, by Tonelli's theorem. Differentiation In the one-variable case, where d/dx is the derivative.

as often just written as . Calorimetry through phase change, equation of state shows one jump discontinuity An early calorimeter was that used by Laplace and Lavoisier, as shown in the figure above. It worked at constant temperature, and at atmospheric pressure. The latent heat involved was then not a latent heat with respect to volume or with respect to pressure, as in the above account for calorimetry without phase change. The latent heat involved in this calorimeter was with respect to phase change, naturally occurring at constant temperature. This kind of calorimeter worked by measurement of mass of water produced by the melting of ice, which is a phase change. Cumulation of heating For a time-dependent process of heating of the calorimetric material, defined by a continuous joint progression of and , starting at time and ending at time , there can be calculated an accumulated quantity of heat delivered, . This calculation is done by mathematical integration along the progression with respect to time. This is because increments of heat are 'additive'; but this does not mean that heat is a conservative quantity. The idea that heat was a conservative quantity was invented by Lavoisier, and is called the 'caloric theory'; by the middle of the nineteenth century it was recognized as mistaken. Written with the symbol , the quantity is not at all restricted to be an increment with very small values; this is in contrast with . One can write . This expression uses quantities such as which are defined in the section below headed 'Mathematical aspects of the above rules'. Mathematical aspects of the above rules The use of 'very small' quantities such as is related to the physical requirement for the quantity to be 'rapidly determined' by and ; such 'rapid determination' refers to a physical process. These 'very small' quantities are used in the Leibniz approach to the infinitesimal calculus. The Newton approach uses instead 'fluxions' such as , which makes it more obvious that must be 'rapidly determined'. In terms of fluxions, the above first rule of calculation can be written where denotes the time denotes the time rate of heating of the calorimetric material at time denotes the time rate of change of volume of the calorimetric material at time denotes the time rate of change of temperature of the calorimetric material. The increment and the fluxion are obtained for a particular time that determines the values of the quantities on the righthand sides of the above rules. But this is not a reason to expect that there should exist a mathematical function . For this reason, the increment is said to be an 'imperfect differential' or an 'inexact differential'. Some books indicate this by writing instead of . Also, the notation đQ is used in some books. Carelessness about this can lead to error. The quantity is properly said to be a functional of the continuous joint progression of and , but, in the mathematical definition of a function, is not a function of . Although the fluxion is defined here as a function of time , the symbols and respectively standing alone are not defined here. Physical scope of the above rules of calorimetry The above rules refer only to suitable calorimetric materials. The terms 'rapidly' and 'very small' call for empirical physical checking of the domain of validity of the above rules. The above rules for the calculation of heat belong to pure calorimetry. They make no reference to thermodynamics, and were mostly understood before the advent of thermodynamics. They are the basis of the 'thermo' contribution to thermodynamics. The 'dynamics' contribution is based on the idea of work, which is not used in the above rules of calculation. Experimentally conveniently measured coefficients Empirically, it is convenient to measure properties of calorimetric materials under experimentally controlled conditions. Pressure increase at constant volume For measurements at experimentally controlled volume, one can use the assumption, stated above, that the pressure of the body of calorimetric material is can be expressed as a function of its volume and temperature. For measurement at constant experimentally controlled volume, the isochoric coefficient of pressure rise with temperature, is defined by . Expansion at constant pressure For measurements at experimentally controlled pressure, it is assumed that the volume of the body of calorimetric material can be expressed as a function of its temperature and pressure . This assumption is related to, but is not the same as, the above used assumption that the pressure of the body of calorimetric material is known as a function of its volume and temperature; anomalous behaviour of materials can affect this relation. The quantity that is conveniently measured at constant experimentally controlled pressure, the isobar volume expansion coefficient, is defined by . Compressibility at constant temperature For measurements at experimentally controlled temperature, it is again assumed that the volume of the body of calorimetric material can be expressed as a function of its temperature and pressure , with the same provisos as mentioned just above. The quantity that is conveniently measured at constant experimentally controlled temperature, the isothermal compressibility, is defined by . Relation between classical calorimetric quantities Assuming that the rule is known, one can derive the function of that is used above in the classical heat calculation with respect to pressure. This function can be found experimentally from the coefficients and through the mathematically deducible relation . Connection between calorimetry and thermodynamics Thermodynamics developed gradually over the first half of the nineteenth century, building on the above theory of calorimetry which had been worked out before it, and on other discoveries. According to Gislason and Craig (2005): "Most thermodynamic data come from calorimetry..." According to Kondepudi (2008): "Calorimetry is widely used in present day laboratories." In terms of thermodynamics, the internal energy of the calorimetric material can be considered as the value of a function of , with partial derivatives and . Then it can be shown that one can write a thermodynamic version of the above calorimetric rules: with and . Again, further in terms of thermodynamics, the internal energy of the calorimetric material can sometimes, depending on the calorimetric material, be considered as the value of a function of , with partial derivatives and , and with being expressible as the value of a function of , with partial derivatives and . Then, according to Adkins (1975), it can be shown that one can write a further thermodynamic version of the above calorimetric rules: with and . Beyond the calorimetric fact noted above that the latent heats and are always of opposite sign, it may be shown, using the thermodynamic concept of work, that also Special interest of thermodynamics in calorimetry: the isothermal segments of a Carnot cycle Calorimetry has a special benefit for thermodynamics. It tells about the heat absorbed or emitted in the isothermal segment of a Carnot cycle. A Carnot cycle is a special kind of cyclic process affecting a body composed of material suitable for use in a heat engine. Such a material is of the kind considered in calorimetry, as noted above, that exerts a pressure that is very rapidly determined just by temperature and volume. Such a body is said to change reversibly. A Carnot cycle consists of four successive stages or segments: (1) a change in volume from a volume to a volume at constant temperature so as to incur a flow of heat into the body (known as an isothermal change) (2) a change in volume from to a volume at a variable temperature just such as to incur no flow of heat (known as an adiabatic change) (3) another isothermal change in volume from to a volume at constant temperature such as to incur a flow or heat out of the body and just such as to precisely prepare for the following change (4) another adiabatic change of volume from back to just such as to return the body to its starting temperature . In isothermal segment (1), the heat that flows into the body is given by and in isothermal segment (3) the heat that flows out of the body is given by . Because the segments (2) and (4) are adiabats, no heat flows into or out of the body during them, and consequently the net heat supplied to the body during the cycle is given by . This quantity is used by thermodynamics and is related in a special way to the net work done by the body during the Carnot cycle. The

The net change of the body's internal energy during the Carnot cycle, , is equal to zero, because the material of the working body has the special properties noted above. Special interest of calorimetry in thermodynamics: relations between classical calorimetric quantities Relation of latent heat with respect to volume, and the equation of state The quantity , the latent heat with respect to volume, belongs to classical calorimetry. It accounts for the occurrence of energy transfer by work in a process in which heat is also transferred; the quantity, however, was considered before the relation between heat and work transfers was clarified by the invention of thermodynamics. In the light of thermodynamics, the classical calorimetric quantity is revealed as being tightly linked to the calorimetric material's equation of state . Provided that the temperature is measured in the thermodynamic absolute scale, the relation is expressed in the formula . Difference of specific heats Advanced thermodynamics provides the relation . From this, further mathematical and thermodynamic reasoning leads to another relation between classical calorimetric quantities. The difference of specific heats is given by . Practical constant-volume calorimetry (bomb calorimetry) for thermodynamic studies Constant-volume calorimetry is calorimetry performed at a constant volume. This involves the use of a constant-volume calorimeter. No work is performed in constant-volume calorimetry, so the heat measured equals the change in internal energy of the system. The heat capacity at constant volume is assumed to be independent of temperature. Heat is measured by the principle of calorimetry. where ΔU is change in internal energy, ΔT is change in temperature and CV is the heat capacity at constant volume. In constant-volume calorimetry the pressure is not held constant. If there is a pressure difference between initial and final states, the heat measured needs adjustment to provide the enthalpy change. One then has where ΔH is change in enthalpy and V is the unchanging volume of the sample chamber.

in the firm in 1888, and the firm changed its name to Carter, Hughes & Cravath (it later became known as Hughes Hubbard & Reed). Hughes left the firm and became a professor at Cornell Law School from 1891 to 1893. He returned to Carter, Hughes & Cravath in 1893. He also joined the board of Brown University and served on a special committee that recommended revisions to New York's Code of Civil Procedure. Responding to newspaper stories run by the New York World, Governor Frank W. Higgins appointed a legislative committee to investigate the state's public utilities in 1905. On the recommendation of a former state judge who had been impressed by Hughes's performance in court, the legislative committee appointed Hughes to lead the investigation. Hughes was reluctant to take on the powerful utility companies, but Senator Frederick C. Stevens, the leader of the committee, convinced Hughes to accept the position. Hughes decided to center his investigation on Consolidated Gas, which controlled the production and sale of gas in New York City. Though few expected the committee to have any impact on public corruption, Hughes was able to show that Consolidated Gas had engaged in a pattern of tax evasion and fraudulent bookkeeping. To eliminate or mitigate those abuses, Hughes drafted and convinced the state legislature to pass bills that established a commission to regulate public utilities and lowered gas prices. Hughes's success made him a popular public figure in New York, and he was appointed counsel to the Armstrong Insurance Commission, which investigated the major life insurance companies headquartered in New York. His examination of the insurance industry uncovered payments made to journalists and lobbyists as well as payments and other forms of compensation directed to legislators serving throughout the country. His investigation also showed that many top insurance executives had various conflicts of interest and had received huge raises at the same time that dividends to policyholders had fallen. Seeking to remove Hughes from the investigation, Republican leaders nominated him as the party's candidate for Mayor of New York City, but Hughes refused the nomination. His efforts ultimately resulted in the resignation or firing of the most of the top-ranking officials in the three major life insurance companies in the United States. Following the investigation, Hughes convinced the state legislature to bar insurance companies from owning corporate stock, underwriting securities, or engaging in other banking practices. Governor of New York Seeking a strong candidate to defeat newspaper mogul William Randolph Hearst in the 1906 New York gubernatorial election, President Theodore Roosevelt convinced New York Republican leaders to nominate Hughes for governor. Roosevelt described Hughes as "a sane and sincere reformer, who really has fought against the very evils which Hearst denounces,... [but is] free from any taint of demagogy." In his campaign for governor, Hughes attacked the corruption of specific companies but defended corporations as a necessary part of the economy. He also called for an eight-hour workday on public works projects and favored prohibitions on child labor. Hughes was not a charismatic speaker, but he campaigned vigorously throughout the state and won the endorsements of most newspapers. Ultimately, Hughes defeated Hearst in a close election, taking 52 percent of the vote. Hughes's governorship focused largely on reforming the government and addressing political corruption. He expanded the number of civil service positions, increased the power of the public utility regulatory commissions, and won passage of laws that placed limits on political donations by corporations and required political candidates to track campaign receipts and expenditures. He also signed laws that barred younger workers from several dangerous occupations and established a maximum 48-hour workweek for manufacturing workers under the age of 16. To enforce those laws, Hughes reorganized the New York State Department of Labor. Hughes's labor policies were influenced by economist Richard T. Ely, who sought to improve working conditions for laborers, but rejected the more far-reaching reforms favored by union leaders like Samuel Gompers. Despite his busyness as New York governor, Hughes found time to get involved in religious matters. A lifelong Baptist, he participated in the creation of the Northern Baptist Convention in May 1907. Hughes served the convention as its first president, beginning the task of unifying the thousands of independent Baptist churches across the North into one denomination. Previously, northern Baptists had only connected between local churches through mission societies and benevolent causes. The Northern Baptist Convention went on to become the historically-important American Baptist Churches USA, which made this aspect of Hughes's life during his governorship a key part of his historical influence. However, Hughes's political role was changing. He had previously been close with Roosevelt, but relations between Hughes and the president cooled after a dispute over a minor federal appointment. Roosevelt chose not to seek re-election in 1908, instead endorsing Secretary of War William Howard Taft as his preferred successor. Taft won the Republican presidential nomination and asked Hughes to serve as his running mate, but Hughes declined the offer. Hughes also considered retiring from the governorship, but Taft and Roosevelt convinced him to seek a second term. Despite having little support among some of the more conservative leaders of the state party, Hughes won re-election in the 1908 election. Hughes's second term proved to be less successful than his first, but he increased regulation over telephone and telegraph companies and won passage of the first workers' compensation bill in U.S. history. Associate Justice By early 1910, Hughes was anxious to retire from his position as governor. A vacancy on the Supreme Court arose following the death of Associate Justice David J. Brewer, and Taft offered the position to Hughes. Hughes quickly accepted the offer, and he was unanimously confirmed by the Senate on May 2, 1910. Two months after Hughes's confirmation, but prior to his taking the judicial oath, Chief Justice Melville Fuller died. Taft elevated Associate Justice Edward Douglass White to the position of Chief Justice despite having previously indicated to Hughes that he might select Hughes as Chief Justice. White's candidacy for the position was bolstered by his long experience on the bench and popularity among his fellow justices, as well as Theodore Roosevelt's coolness towards Hughes. Taft nominated Willis Van Devanter to succeed White as associate justice. Hughes, who was sworn into office on October 10, 1910, quickly struck up friendships with other members of the Supreme Court, including Chief Justice White, Associate Justice John Marshall Harlan, and Associate Justice Oliver Wendell Holmes Jr. In the disposition of cases, however, Hughes tended to align with Holmes. He voted to uphold state laws providing for minimum wages, workmen's compensation, and maximum work hours for women and children. He also wrote several opinions upholding the power of Congress to regulate interstate commerce under the Commerce Clause. His majority opinion in Baltimore & Ohio Railroad vs. Interstate Commerce Commission upheld the right of the federal government to regulate the hours of railroad workers. His majority opinion in the 1914 Shreveport Rate Case upheld the Interstate Commerce Commission's decision to void discriminatory railroad rates imposed by the Railroad Commission of Texas. The decision established that the federal government could regulate intrastate commerce when it affected interstate commerce, though Hughes avoided directly overruling the 1895 case of United States v. E. C. Knight Co. He also wrote a series of opinions that upheld civil liberties; in one such case, McCabe v. Atchison, Topeka & Santa Fe Railway Co., Hughes's majority opinion required railroad carriers to give African-Americans "equal treatment." Hughes's majority opinion in Bailey v. Alabama invalidated a state law that had made it a crime for a laborer to fail to complete obligations agreed to in a labor contract. Hughes held that this law violated the Thirteenth Amendment and discriminated against African-American workers. He also joined the majority decision in the 1915 case of Guinn v. United States, which outlawed the use of grandfather clauses to determine voter enfranchisement. Hughes and Holmes were the only dissenters from the court's ruling that affirmed a lower court's decision to withhold a writ of habeas corpus from Leo Frank, a Jewish factory manager convicted of murder in the state of Georgia. Presidential candidate Taft and Roosevelt endured a bitter split during Taft's presidency, and Roosevelt challenged Taft for the 1912 Republican presidential nomination. Taft won re-nomination, but Roosevelt ran on the ticket of a third party, the Progressive Party. With the split in the Republican Party, Democratic Governor Woodrow Wilson defeated Taft and Roosevelt in the 1912 presidential election and enacted his progressive New Freedom agenda. Seeking to bridge the divide in the Republican Party and limit Wilson to a single term, several Republican leaders asked Hughes to consider running in the 1916 presidential election. Hughes at first rebuffed those entreaties, but his potential candidacy became the subject of widespread speculation and polls showed that he was the preferred candidate of many Republican voters. By the time of the June 1916 Republican National Convention, Hughes had won two presidential primaries, and his backers had lined up the support of numerous delegates. Hughes led on the first presidential ballot of the convention and clinched the nomination on the third ballot. Hughes accepted the nomination, becoming the first and only sitting Supreme Court Justice to serve as a major party's presidential nominee, and submitted his resignation to President Wilson. Roosevelt, meanwhile, declined to run again on a third party ticket, leaving Hughes and Wilson as the only major candidates in the race. Because of the Republican Party's dominance in presidential elections held since the election of Abraham Lincoln in 1860, Hughes was widely regarded as the favorite even though Wilson was the incumbent. His candidacy was further boosted by his own reputation for intelligence, personal integrity, and moderation. Hughes also won the public support of both Taft and Roosevelt, though Roosevelt remained uneasy with Hughes, whom he feared would be a "Wilson with whiskers." However, the split in Republican ranks remained a lingering issue, and Hughes damaged his campaign by inadvertently snubbing Hiram Johnson, the Governor of California who had been Roosevelt's running mate in the 1912 election. Because of Hughes's opposition to the Adamson Act and the Sixteenth Amendment, most former Progressive Party leaders endorsed Wilson. By election day, Hughes was still generally considered to be the favorite. He performed strongly in the Northeast and early election returns nearly convinced Wilson to concede the election. However, Wilson swept the Solid South and won several victories in the Midwest, where his candidacy was boosted by a strong pacifist sentiment. Wilson ultimately prevailed after winning the state of California by fewer than 4,000 votes. After the election, Hughes turned down offers from larger organizations and returned to his small law firm, now known as Hughes, Rounds, Schurman & Dwight. In March 1917, Hughes joined with many other Republican leaders in demanding that Wilson declare war on the Central Powers after Germany sank several American merchant ships. The next month, Wilson asked Congress for a declaration of war, and the United States entered World War I. Hughes supported Wilson's military policies, including the imposition of the draft, and he served as chairman of New York City's draft appeals board. He also investigated the aircraft industry on behalf of the Wilson administration, exposing numerous inefficiencies. He once again returned to private practice after the war, serving a wide array of clients, including five Socialists who had been expelled from the New York legislature for their political beliefs. He sought to broker a compromise between President Wilson and Senate Republicans regarding US entrance into Wilson's proposed League of Nations, but the Senate rejected the League and the Treaty of Versailles. With Wilson's popularity declining, many Republican leaders believed that their party would win the 1920 presidential election. Hughes remained popular in the party, and many influential Republicans favored him as the party's candidate in 1920. Hughes was struck by personal disaster when his daughter, Helen, died in 1920 of tuberculosis, and he refused to allow his name to be considered for the presidential nomination at the 1920 Republican National Convention. The party instead nominated a ticket consisting of Senator Warren G. Harding of Ohio and Governor Calvin Coolidge of Massachusetts. The Republican ticket won in a landslide, taking 61 percent of the popular vote. Secretary of State Shortly after Harding's victory in the 1920 election, Hughes accepted the position of Secretary of State. After the death of Chief Justice White in May 1921, Hughes was mentioned as a potential successor. Hughes told Harding he was uninterested in leaving the State Department, and Harding instead appointed former President Taft as the Chief Justice. Harding granted Hughes a great deal of discretion in his leadership of the State Department and US foreign policy. Harding and Hughes frequently communicated, Hughes worked within some broad outlines, and the president remained well-informed. But the president rarely overrode any of Hughes's decisions, with the big and obvious exception of the League of Nations. After taking office, President Harding hardened his stance on the League of Nations, deciding the US would not join even a scaled-down version. Or, another view is that Harding favored joining with reservations when he assumed office on March 4, 1921, but that Senators staunchly opposed (the "Irreconcilables"), per Ron Powaski's 1991 book, "threatened to wreck the new administration." Hughes favored membership in the League. Early in his tenure as Secretary of State, he asked the Senate to vote on the Treaty of Versailles, but he yielded to either Harding's changing views and/or political reality within the Senate. Instead, he convinced Harding of the necessity of a separate treaty with Germany, resulting in the signing and eventual ratification of the U.S.–German Peace Treaty. Hughes also favored US entrance into the Permanent Court of International Justice, but was unable to convince the Senate to provide support. Washington Naval Treaty Hughes's major initiative in office was preventing an arms race among the three great naval powers of Britain, Japan, and the United States. After Senator William Borah led passage of a resolution calling on the Harding administration to negotiate an arms reduction treaty with Japan and Britain, Hughes convinced those countries as well as Italy and France to attend a naval conference in Washington. Hughes selected an American delegation consisting of himself, former Secretary of State Elihu Root, Republican Senator Henry Cabot Lodge, and Democratic Senator Oscar Underwood. Hughes hoped that the selection of Underwood would ensure bipartisan support for any treaty arising from the conference. Prior to the conference, Hughes had carefully considered possible treaty terms since each side would seek terms that would provide their respective navy with subtle advantages. He decided to propose an arms reduction formula based on the immediate halting of all naval construction, with future construction limits based on the ship tonnage of each country. The formula would be based on the ship tonnage ratio of 1920, which stood at roughly 5:5:3 for the United States, Britain, and Japan, respectively. Knowing that US and foreign naval leaders would resist his proposal, he anxiously guarded it from the press, but he won the support of Root, Lodge, and Underwood. The Washington Naval Conference opened

After Senator William Borah led passage of a resolution calling on the Harding administration to negotiate an arms reduction treaty with Japan and Britain, Hughes convinced those countries as well as Italy and France to attend a naval conference in Washington. Hughes selected an American delegation consisting of himself, former Secretary of State Elihu Root, Republican Senator Henry Cabot Lodge, and Democratic Senator Oscar Underwood.

Knowing that US and foreign naval leaders would resist his proposal, he anxiously guarded it from the press, but he won the support of Root, Lodge, and Underwood. The Washington Naval Conference opened in November 1921, attended by five national delegations, and, in the gallery, hundreds of reporters and dignitaries such as Chief Justice Taft and William Jennings Bryan. On the first day of the conference, Hughes unveiled his proposal to limit naval armaments. Hughes's ambitious proposal to scrap all US capital ships under construction stunned the delegates, as did his proposals for the Japanese and British navies. The British delegation, led by Arthur Balfour, supported the proposal, but the Japanese delegation, under the leadership of Katō Tomosaburō, asked for several modifications. Katō asked that the ratio be adjusted to 10:10:7 and refused to destroy the Mutsu, a dreadnought that many Japanese saw as a symbol of national pride. Katō eventually relented on the naval ratios, but Hughes acquiesced to the retention of the Mutsu, leading to protests from British leaders. Hughes clinched an agreement after convincing Balfour to agree to limit the size of the Admiral-class battlecruisers despite objections from the British navy. Hughes also won agreement on the Four-Power Treaty, which called for a peaceful resolution of territorial claims in the Pacific Ocean, as well as the Nine-Power Treaty, which guaranteed the territorial integrity of China. News of the success of the conference was warmly received around the world. Franklin D. Roosevelt later wrote that the conference "brought to the world the first important voluntary agreement for limitation and reduction of armament." Other issues In the aftermath of World War I, the German economy struggled from the strain of postwar rebuilding and war reparations owed to the Entente, while the Entente powers in turn owed large war debts to the United States. Though many economists favored cancellation of all European war debts, French leaders were unwilling to cancel the reparations, and Congress refused to consider forgiving the war debts. Hughes helped organize the creation of an international committee of economists to study the possibility of lowering Germany's reparations, and Hughes selected Charles G. Dawes to lead that committee. The resulting Dawes Plan, which provided for annual payments by Germany, was accepted at a 1924 conference held in London. Hughes favored a closer relationship with the United Kingdom, and sought to coordinate U.S. foreign policy with Great Britain where it concerned matters of Europe and Asia. Hughes sought better relations with the countries of Latin America, and he favored removing US troops when he believed that doing so was practicable. He formulated plans for the withdrawal of US soldiers from the Dominican Republic and Nicaragua but decided that instability in Haiti required the continued presence of U.S. soldiers. He also settled a border dispute between Panama and Costa Rica by threatening to send soldiers into Panama. Hughes was the keynote speaker at the 1919 National Conference on Lynching. Return to private practice Hughes stayed on as Secretary of State in the Coolidge administration after the death of Harding in 1923, but he left office in early 1925. He once again returned to his law firm, becoming one of the highest-earning lawyers in the country. He also served as a special master in a case concerning Chicago's sewage system, was elected president of the American Bar Association, and co-founded the National Conference on Christians and Jews. State party leaders asked him to run against Al Smith in New York's 1926 gubernatorial election, and some national party leaders suggested that he run for president in 1928, but Hughes declined to seek public office. After the 1928 Republican National Convention nominated Herbert Hoover, Hughes gave Hoover his full support and campaigned for him across the United States. Hoover won the election in a landslide and asked Hughes to serve as his Secretary of State, but Hughes declined the offer to keep his commitment to serve as a judge on the Permanent Court of International Justice. Chief Justice Rejoining the Court On February 3, 1930, President Hoover nominated Hughes to succeed Chief Justice Taft, who was gravely ill. Though many had expected Hoover to elevate his close friend, Associate Justice Harlan Stone, Hughes was the top choice of Taft and Attorney General William D. Mitchell. Though Hughes had compiled a progressive record during his tenure as an Associate Justice, by 1930 Taft believed that Hughes would be a consistent conservative on the court. The nomination faced resistance from progressive Republicans such as senators George W. Norris and William E. Borah, who were concerned that Hughes would be overly friendly to big business after working as a corporate lawyer. Many of those progressives, as well some Southern states' rights advocates, were outraged by the Taft Court's tendency to strike down state and federal legislation on the basis of the doctrine of substantive due process and feared that a Hughes Court would emulate the Taft Court. Adherents of the substantive due process doctrine held that economic regulations such as restrictions on child labor and minimum wages violated freedom of contract, which, they argued, could not be abridged by federal and state laws because of the Fifth Amendment and the Fourteenth Amendment. After a brief but bitter confirmation battle, Hughes was confirmed by the Senate in a 52–26 vote, and took his judicial oath of office on February 24, 1930. Hughes's son, Charles Jr., was subsequently forced to resign as Solicitor General after his father took office as Chief Justice. Hughes quickly emerged as a leader of the Court, earning the admiration of his fellow justices for his intelligence, energy, and strong understanding of the law. Shortly after Hughes was confirmed, Hoover nominated federal judge John J. Parker to succeed deceased Associate Justice Edward Terry Sanford. The Senate rejected Parker, whose earlier rulings had alienated labor unions and the NAACP, but confirmed Hoover's second nominee, Owen Roberts. In early 1932, the other justices asked Hughes to request the resignation of Oliver Wendell Holmes, whose health had declined as he entered his nineties. Hughes privately asked his old friend to retire, and Holmes immediately sent a letter of resignation to President Hoover. To replace Holmes, Hoover nominated Benjamin N. Cardozo, who quickly won confirmation. The early Hughes Court was divided between the conservative "Four Horsemen" and the liberal "Three Musketeers". The primary difference between these two blocs was that the Four Horsemen embraced the substantive due process doctrine, but the liberals, including Louis Brandeis, advocated for judicial restraint, or deference to legislative bodies. Hughes and Roberts were the swing justices between the two blocs for much of the 1930s. In one of the first major cases of his tenure, Hughes joined with Roberts and the Three Musketeers to strike down a piece of state legislation in the 1931 landmark case of Near v. Minnesota. In his majority opinion, Hughes held that the First Amendment barred states from violating freedom of the press. Hughes also wrote the majority opinion in Stromberg v. California, which represented the first time the Supreme Court struck down a state law on the basis of the incorporation of the Bill of Rights. In another early case, O'Gorman & Young, Inc. v. Hartford Fire Insurance Co., Hughes and Roberts joined with the liberal bloc in upholding a state regulation that limited commissions for the sale of fire insurance. Roosevelt takes office During Hoover's presidency, the country plunged into the Great Depression. As the country faced an ongoing economic calamity, Franklin D. Roosevelt decisively defeated Hoover in the 1932 presidential election. Responding to the Great Depression, Roosevelt passed a bevy of domestic legislation as part of his New Deal domestic program, and the response to the New Deal became one of the key issues facing the Hughes Court. In the Gold Clause Cases, a series of cases that presented some of the first major tests of New Deal laws, the Hughes Court upheld restrictions on the ownership of gold that were favored by the Roosevelt administration. Roosevelt, who had expected the Supreme Court to rule adversely to his administration's position, was elated by the outcome, writing that "as a lawyer it seems to me that the Supreme Court has at last definitely put human values ahead of the 'pound of flesh' called for by a contract." The Hughes Court also continued to adjudicate major cases concerning the states. In the 1934 case of Home Building & Loan Ass'n v. Blaisdell, Hughes and Roberts joined the Three Musketeers in upholding a Minnesota law that established a moratorium on mortgage payments. Hughes's majority opinion in that case stated that "while an emergency does not create power, an emergency may furnish the occasion for the exercise of power." Beginning with the 1935 case of Railroad Retirement Board v. Alton Railroad Co., Roberts started siding with the Four Horsemen, creating a majority bloc that struck down New Deal laws. The court held that Congress had, in passing an act that provided a mandatory retirement and pension system for railroad industry workers, violated due process and exceeded the regulatory powers granted to it by the Commerce Clause. Hughes strongly criticized Roberts's majority opinion in his dissent, writing that "the power committed to Congress to govern interstate commerce does not require that its government should be wise, much less that it be perfect. The power implies a broad discretion." Nonetheless, in May 1935, the Supreme Court unanimously struck down three New Deal laws. Writing the majority opinion in A.L.A. Schechter Poultry Corp. v. United States, Hughes held that Roosevelt's National Industrial Recovery Act of 1933 was doubly unconstitutional, falling afoul of both the Commerce Clause and the nondelegation doctrine. In the 1936 case of United States v. Butler, Hughes surprised many observers by joining with Roberts and the Four Horsemen in striking down the Agricultural Adjustment Act. In doing so, the court dismantled the Agricultural Adjustment Administration, the major New Deal agricultural program. In another 1936 case, Carter v. Carter Coal Co., the Supreme Court struck down the Guffey Coal Act, which regulated the bituminous coal industry. Hughes wrote a concurring opinion in Carter in which he agreed with the majority's holding that Congress could not use its Commerce Clause powers to "regulate activities and relations within the states which affect interstate commerce only indirectly." In the final case of the 1936 term, Morehead v. New York ex rel. Tipaldo, Roberts joined with the Four Horsemen in striking down New York's minimum wage law. President Roosevelt had held up the New York minimum wage law as a model for other states to follow, and many Republicans as well as Democrats attacked the decision for interfering with the states. In December 1936, the court handed down its near-unanimous opinion in United States v. Curtiss-Wright Export Corp., upholding a law that granted the president the power to place an arms embargo on Bolivia and Paraguay. Justice Sutherland's majority opinion, which Hughes joined,

According to biographer Will Friedwald, Sinatra "sequenced the songs so that the lyrics created a flow from track to track, affording an impression of a narrative, as in musical comedy or opera. ... [He was the] first pop singer to bring a consciously artistic attitude to recording." Singer/pianist Nat "King" Cole (who, along with Sinatra, often collaborated with arranger Nelson Riddle during this era) was also an early pioneer of concept albums, as with his Wild Is Love (1960), a suite of original songs about a man's search for love. 1960s: Rock and country music In the early 1960s, concept albums began featuring highly in American country music, however the fact went largely unacknowledged by rock/pop fans and critics who would only begin noting "concept albums" as a phenomenon later in the decade, when albums became closely aligned with countercultural ideology, resulting in a recognised "album era" and the introduction of the rock concept album. The author Carys Wyn Jones writes that the Beach Boys' Pet Sounds (1966), the Beatles' Revolver (1966) and Sgt. Pepper's Lonely Hearts Club Band (1967), and the Who's Tommy (1969) are variously cited as "the first concept album", usually for their "uniform excellence rather than some lyrical theme or underlying musical motif". Other records have been claimed as "early" or "first" concept albums. The 100 Greatest Bands of All Time (2015) states that the Ventures "pioneered the idea of the rock concept album years before the genre is generally acknowledged to have been born" with their 1964 album The Ventures in Space. Another is the Beach Boys' Little Deuce Coupe (1963). Writing in 101 Albums That Changed Popular Music, Chris Smith commented: "Though albums such as Frank Sinatra's 1955 In the Wee Small Hours and Marty Robbins' 1959 Gunfighter Ballads and Trail Songs had already introduced concept albums, Little Deuce Coupe was the first to comprise almost all original material rather than standard covers." Writing in his Concise Dictionary of Popular Culture, Marcel Danesi identifies the Beatles' Rubber Soul (1965) and the Who's The Who Sell Out (1967) as other examples of early concept albums. Brian Boyd of The Irish Times names the Kinks' Face to Face (1966) as the first concept album: "Written entirely by Ray Davies, the songs were supposed to be linked by pieces of music, so that the album would play without gaps, but the record company baulked at such radicalism. It’s not one of the band’s finest works, but it did have an impact." "Popular consensus" for the first rock concept album, according to AllMusic, favours Sgt. Pepper. According to music critic Tim Riley, "Strictly speaking, the Mothers of Invention's Freak Out! [1966] has claims as the first 'concept album', but Sgt. Pepper was the record that made that idea convincing to most ears." Musicologist Allan Moore says that "Even though previous albums had set a unified mood (notably Sinatra's Songs for Swinging Lovers), it was on the basis of the influence of Sgt. Pepper that the penchant for the concept album was born." Adding to Sgt. Peppers claim, the artwork reinforced its central theme by depicting the four Beatles in uniform as members of the Sgt. Pepper band, while the record omitted the gaps that usually separated album tracks. Music critic and journalist Neil Slaven stated that Frank Zappa's Absolutely Free, released the same day as Sgt. Pepper, was "very much a concept album, but The Beatles effortlessly stole his thunder", and subsequently Sgt. Pepper was hailed as "perhaps the first 'concept album' even though the songs were unrelated" 1960s–70s: Rock operas and progressive rock Author Bill Martin relates the assumed concept albums of the 1960s to progressive rock: Popmatters Sarah Zupko notes that while the Who's Tommy is

Sorrow (The Pretty Things, 1968). Author Jim Cullen states: "The concept album reached its apogee in the 1970s in ambitious records like Pink Floyd's Dark Side of the Moon (1973) and the Eagles' Hotel California (1976)." In 2015, Rolling Stone ranked Dark Side of the Moon at number one among the 50 greatest progressive rock albums of all-time, also noting the LP's stature as the second best-selling album of all time. Pink Floyd's The Wall (1979), a semi-autobiographical story modeled after the band's Roger Waters and Syd Barrett, is one of the most famous concept albums by any artist. In addition to The Wall, Danesi highlights Genesis' The Lamb Lies Down on Broadway (1974) and Frank Zappa's Joe's Garage (1979) as other culturally significant concept albums. According to author Edward Macan, concept albums as a recurrent theme in progressive rock was directly inspired by the counterculture associated with "the proto-progressive bands of the 1960s", observing: "the consistent use of

but mainly flourished in German-speaking lands, Scandinavia, and the Iberian Peninsula in the latter part of this period. It had fallen out of use by 1850. In the late 1890s, Arnold Dolmetsch revived clavichord construction and Violet Gordon-Woodhouse, among others, helped to popularize the instrument. Although most of the instruments built before the 1730s were small (four octaves, four feet long), the latest instruments were built up to seven feet long with a six octave range. Until electronic amplification in the twentieth century, it was impossible to use the quiet clavichord in anything but a small room. However, during the clavichord's heyday, evenings of music-making in the home formed the largest part of people's musical experiences. In the home the clavichord was the ideal instrument for solo keyboard music and instrumental accompaniment. Today clavichords are played primarily by Renaissance, Baroque, and Classical music enthusiasts. They attract many interested buyers, and are manufactured worldwide. There are now numerous clavichord societies around the world, and some 400 recordings of the instrument have been made in the past 70 years. Leading modern exponents of the instrument have included Christopher Hogwood and Thurston Dart. Modern music The clavichord has also gained attention in other genres of music, in the form of the Clavinet, which is a solid body electric clavichord with magnetic pickups that plug into an amp. Stevie Wonder uses a Clavinet in many of his songs, such as "Superstition" and "Higher Ground". A Clavinet played through an instrument amplifier with guitar effect pedals is often associated with funky, disco-infused 1970s rock. Guy Sigsworth has played clavichord in a modern setting with Björk, notably on the studio recording of "All Is Full of Love". Björk also made extensive use of and even played the instrument herself on the song "My Juvenile" of her 2007 album Volta. Tori Amos uses the instrument on "Little Amsterdam" from the album Boys for Pele and on the song "Smokey Joe" from her 2007 album American Doll Posse. Amos also featured her use of the Clavinet on her 2004 recording "Not David Bowie", released as part of her 2006 box set, A Piano: The Collection. In 1976 Oscar Peterson played (with Joe Pass on acoustic guitar) songs from Porgy And Bess on the clavichord. Keith Jarrett also recorded an album entitled Book of Ways (1986) in which he plays a series of clavichord improvisations. The Beatles' "For No One" (1966) features Paul McCartney playing the clavichord. Rick Wakeman plays the Clavinet in the track "The Battle" from the album Journey to the Centre of the Earth. Structure and action In the clavichord, strings run transversely from the hitchpin rail at the left-hand end to tuning pegs on the right. Towards the right end they pass over a curved wooden bridge. The action is simple, with the keys being levers with a small brass tangent, a small piece of metal similar in shape and size to the head of a flat-bladed screwdriver, at the far end. The strings, which are usually of brass, or else a combination of brass and iron, are usually arranged in pairs, like a lute or mandolin. When the key is pressed, the tangent strikes the strings above, causing them to sound in a similar fashion to the hammering technique on a guitar. Unlike in a piano action, the tangent does not rebound from the string; rather, it stays in contact with the string as long as the key is held, acting as both the nut and as the initiator of sound. The volume of the note can be changed by striking harder or softer, and the pitch can also be affected by varying the force of the tangent against the string (known as Bebung). When the key is released, the tangent loses
Because of this intimate contact between the player's hand and the production of sound, the clavichord has been referred to as the most intimate of keyboard instruments. Despite its many (serious) limitations, including extremely low volume, it has considerable expressive power, the player being able to control attack, duration, and volume, and even provide certain subtle effects of swelling of tone and a type of vibrato unique to the clavichord. Fretting Since the string vibrates from the bridge only as far as the tangent, multiple keys with multiple tangents can be assigned to the same string. This is called fretting. Early clavichords frequently had many notes played on each string, even going so far as the keyed monochord—an instrument with only one string—though most clavichords were triple- or double-fretted. Since only one note can be played at a time on each string, the fretting pattern is generally chosen so that notes rarely heard together (such as C and C) share a string pair. The advantages of this system compared with unfretted instruments (see below) include relative ease of tuning (with around half as many strings to keep in tune), greater volume (though still not really enough for use in chamber music), and a clearer, more direct sound. Among the disadvantages: temperament could not be re-set without bending the tangents; and playing required a further refinement of touch, since notes sharing a single string played in quick succession had to be slightly separated to avoid a disagreeable deadening of the sound, potentially disturbing a legato line. Some clavichords have been built with a single pair of strings for each note. The first known reference to one was by Johann Speth in 1693 and the earliest such extant signed and dated clavichord was built in 1716 by Johann Michael Heinitz. Such instruments are referred to as unfretted whereas instruments using the same strings for several notes are called fretted. Among the advantages to unfretted instruments are flexibility in tuning (the temperament can be easily altered) and the ability to play any music exactly as written without concern for "bad" notes. Disadvantages include a smaller volume, even though many or most unfretted instruments tend to be significantly larger than fretted instruments; and many more strings to keep in tune. Unfretted instruments tend to have a sweeter, less incisive tone due to the greater load on the bridge resulting from the greater number of strings, though the large, late (early 19th century) Swedish clavichords tend to be the loudest of any of the historic clavichords. Pedal clavichord While clavichords were typically single manual instruments, they could be stacked, one clavichord on top of another, to provide multiple keyboards. With the addition of a pedal clavichord, which included a pedal keyboard for the lower notes, a clavichord could be used to practice organ repertoire. Most often, the addition of a pedal keyboard only involved connecting the keys of the pedalboard to the lower notes on the manual clavichord using string so the lower notes on the manual instrument could be operated by the feet. In the era of pipe organs, which used man-powered bellows that required several people to operate, and of churches only heated during church services if at all, organists used pedal harpsichords and pedal clavichords as practice instruments (see also: pedal piano). There is speculation that some works written for organ may have been intended for pedal clavichord. An interesting case is made by that Bach's "Eight Little Preludes and Fugues", now thought spurious, may actually be authentic. The keyboard writing seems unsuited to organ, but Speerstra argues that they are idiomatic on the pedal clavichord. As Speerstra and also note, the compass of the keyboard parts of Bach's six trio sonatas for organ (BWV 525–530) rarely go below the
the instantaneous center of curvature. Another example of centripetal force arises in the helix that is traced out when a charged particle moves in a uniform magnetic field in the absence of other external forces. In this case, the magnetic force is the centripetal force that acts towards the helix axis. Analysis of several cases Below are three examples of increasing complexity, with derivations of the formulas governing velocity and acceleration. Uniform circular motion Uniform circular motion refers to the case of constant rate of rotation. Here are two approaches to describing this case. Calculus derivation In two dimensions, the position vector , which has magnitude (length) and directed at an angle above the x-axis, can be expressed in Cartesian coordinates using the unit vectors and : The assumption of uniform circular motion requires three things: The object moves only on a circle. The radius of the circle does not change in time. The object moves with constant angular velocity around the circle. Therefore, where is time. The velocity and acceleration of the motion are the first and second derivatives of position with respect to time: The term in parenthesis is the original expression of in Cartesian coordinates. Consequently, negative shows that the acceleration is pointed towards the center of the circle (opposite the radius), hence it is called "centripetal" (i.e. "center-seeking"). While objects naturally follow a straight path (due to inertia), this centripetal acceleration describes the circular motion path caused by a centripetal force. Derivation using vectors The image at right shows the vector relationships for uniform circular motion. The rotation itself is represented by the angular velocity vector Ω, which is normal to the plane of the orbit (using the right-hand rule) and has magnitude given by: with θ the angular position at time t. In this subsection, dθ/dt is assumed constant, independent of time. The distance traveled dℓ of the particle in time dt along the circular path is which, by properties of the vector cross product, has magnitude rdθ and is in the direction tangent to the circular path. Consequently, In other words, Differentiating with respect to time, Lagrange's formula states: Applying Lagrange's formula with the observation that Ω • r(t) = 0 at all times, In words, the acceleration is pointing directly opposite to the radial displacement r at all times, and has a magnitude: where vertical bars |...| denote the vector magnitude, which in the case of r(t) is simply the radius r of the path. This result agrees with the previous section, though the notation is slightly different. When the rate of rotation is made constant in the analysis of nonuniform circular motion, that analysis agrees with this one. A merit of the vector approach is that it is manifestly independent of any coordinate system. Example: The banked turn The upper panel in the image at right shows a ball in circular motion on a banked curve. The curve is banked at an angle θ from the horizontal, and the surface of the road is considered to be slippery. The objective is to find what angle the bank must have so the ball does not slide off the road. Intuition tells us that, on a flat curve with no banking at all, the ball will simply slide off the road; while with a very steep banking, the ball will slide to the center unless it travels the curve rapidly. Apart from any acceleration that might occur in the direction of the path, the lower panel of the image above indicates the forces on the ball. There are two forces; one is the force of gravity vertically downward through the center of mass of the ball mg, where m is the mass of the ball and g is the gravitational acceleration; the second is the upward normal force exerted by the road at a right angle to the road surface man. The centripetal force demanded by the curved motion is also shown above. This centripetal force is not a third force applied to the ball, but rather must be provided by the net force on the ball resulting from vector addition of the normal force and the force of gravity. The resultant or net force on the ball found by vector addition of the normal force exerted by the road and vertical force due to gravity must equal the centripetal force dictated by the need to travel a circular path. The curved motion is maintained so long as this net force provides the centripetal force requisite to the motion. The horizontal net force on the ball is the horizontal component of the force from the road, which has magnitude |Fh| = m|an|sinθ. The vertical component of the force from the road must counteract the gravitational force: |Fv| = m|an|cosθ = m|g|, which implies |an|=|g| / cosθ. Substituting into the above formula for |Fh| yields a horizontal force to be: On the other hand, at velocity |v| on a circular path of radius r, kinematics says that the force needed to turn the ball continuously into the turn is the radially inward centripetal force Fc of magnitude: Consequently, the ball is in a stable path when the angle of the road is set to satisfy the condition: or, As the angle of bank θ approaches 90°, the tangent function approaches infinity, allowing larger values for |v|2/r. In words, this equation states that for greater speeds (bigger |v|) the road must be banked more steeply (a larger value for θ), and for sharper turns (smaller r) the road also must be banked more steeply, which accords with intuition. When the angle θ does not satisfy the above condition, the horizontal component of force exerted by the road does not provide the correct centripetal force, and an additional frictional force tangential to the road surface is called upon to provide the difference. If friction cannot do this (that is, the coefficient of friction is exceeded), the ball slides to a different radius where the balance can be realized. These ideas apply to air flight as well. See the FAA pilot's manual. Nonuniform circular motion As a generalization of the uniform circular motion case, suppose the angular rate of rotation is not constant. The acceleration now has a tangential component, as shown the image at right. This case is used to demonstrate a derivation strategy based on a polar coordinate system. Let r(t) be a vector that describes the position of a point mass as a function of time. Since we are assuming circular motion, let , where R is a constant (the radius of the circle) and ur is the unit vector pointing from the origin to the point mass. The direction of ur is described by θ, the angle between the x-axis and the unit vector, measured counterclockwise from the x-axis. The other unit vector for polar coordinates, uθ is perpendicular to ur and points in the direction of increasing θ. These polar unit vectors can be expressed in terms of Cartesian unit vectors in the x and y directions, denoted i and j respectively: and One can differentiate to find velocity: where is the angular velocity . This result for the velocity matches expectations that the velocity should be directed tangentially to the circle, and that the magnitude of the velocity should be . Differentiating again, and noting that we find that the acceleration, a is: Thus, the radial and tangential components of the acceleration are: and where is the magnitude of the velocity (the speed). These equations express mathematically that, in the case of an object that moves along a circular path with a changing speed, the acceleration of the body may be decomposed into a perpendicular component that changes the direction of motion (the centripetal acceleration), and a parallel, or tangential component, that changes the speed. General planar motion Polar coordinates The above results can be derived perhaps more simply in polar coordinates, and at the same time extended to general motion within a plane, as shown next. Polar coordinates in the plane employ a radial unit vector uρ and an angular unit vector uθ, as shown above. A particle at position r is described by: where the notation ρ is used to describe the distance of the path from the origin instead of R to emphasize that this distance is not fixed, but varies with time. The unit vector uρ travels with the particle and always points in the same direction as r(t). Unit vector uθ also travels with the particle and stays orthogonal to uρ. Thus, uρ and uθ form a local Cartesian coordinate system attached to the particle, and tied to the path traveled by the particle. By moving the unit vectors so their tails coincide, as seen in the circle at the left of the image above, it is seen that uρ and uθ form a right-angled pair with tips on the unit circle that trace back and forth on the perimeter of this circle with the same angle θ(t) as r(t). When the particle moves, its velocity is To evaluate the velocity, the derivative of the unit vector uρ is needed. Because uρ is a unit vector, its magnitude is fixed, and it can change only in direction, that is, its change duρ has a component only perpendicular to uρ. When the trajectory r(t) rotates an amount dθ, uρ, which points in the same direction as r(t),
orthogonal to uρ while the trajectory r(t) rotates an amount dθ, uθ, which is orthogonal to r(t), also rotates by dθ. See image above. Therefore, the change duθ is orthogonal to uθ and proportional to dθ (see image above): The image above shows the sign to be negative: to maintain orthogonality, if duρ is positive with dθ, then duθ must decrease. Substituting the derivative of uρ into the expression for velocity: To obtain the acceleration, another time differentiation is done: Substituting the derivatives of uρ and uθ, the acceleration of the particle is: As a particular example, if the particle moves in a circle of constant radius R, then dρ/dt = 0, v = vθ, and: where These results agree with those above for nonuniform circular motion. See also the article on non-uniform circular motion. If this acceleration is multiplied by the particle mass, the leading term is the centripetal force and the negative of the second term related to angular acceleration is sometimes called the Euler force. For trajectories other than circular motion, for example, the more general trajectory envisioned in the image above, the instantaneous center of rotation and radius of curvature of the trajectory are related only indirectly to the coordinate system defined by uρ and uθ and to the length |r(t)| = ρ. Consequently, in the general case, it is not straightforward to disentangle the centripetal and Euler terms from the above general acceleration equation. To deal directly with this issue, local coordinates are preferable, as discussed next. Local coordinates Local coordinates mean a set of coordinates that travel with the particle, and have orientation determined by the path of the particle. Unit vectors are formed as shown in the image at right, both tangential and normal to the path. This coordinate system sometimes is referred to as intrinsic or path coordinates or nt-coordinates, for normal-tangential, referring to these unit vectors. These coordinates are a very special example of a more general concept of local coordinates from the theory of differential forms. Distance along the path of the particle is the arc length s, considered to be a known function of time. A center of curvature is defined at each position s located a distance ρ (the radius of curvature) from the curve on a line along the normal un (s). The required distance ρ(s) at arc length s is defined in terms of the rate of rotation of the tangent to the curve, which in turn is determined by the path itself. If the orientation of the tangent relative to some starting position is θ(s), then ρ(s) is defined by the derivative dθ/ds: The radius of curvature usually is taken as positive (that is, as an absolute value), while the curvature κ is a signed quantity. A geometric approach to finding the center of curvature and the radius of curvature uses a limiting process leading to the osculating circle. See image above. Using these coordinates, the motion along the path is viewed as a succession of circular paths of ever-changing center, and at each position s constitutes non-uniform circular motion at that position with radius ρ. The local value of the angular rate of rotation then is given by: with the local speed v given by: As for the other examples above, because unit vectors cannot change magnitude, their rate of change is always perpendicular to their direction (see the left-hand insert in the image above): Consequently, the velocity and acceleration are: and using the chain-rule of differentiation: with the tangential acceleration In this local coordinate system, the acceleration resembles the expression for nonuniform circular motion with the local radius ρ(s), and the centripetal acceleration is identified as the second term. Extending this approach to three dimensional space curves leads to the Frenet–Serret formulas. Alternative approach Looking at the image above, one might wonder whether adequate account has been taken of the difference in curvature between ρ(s) and ρ(s + ds) in computing the arc length as ds = ρ(s)dθ. Reassurance on this point can be found using a more formal approach outlined below. This approach also makes connection with the article on curvature. To introduce the unit vectors of the local coordinate system, one approach is to begin in Cartesian coordinates and describe the local coordinates in terms of these Cartesian coordinates. In terms of arc length s, let the path be described as: Then an incremental displacement along the path ds is described by: where primes are introduced to denote derivatives with respect to s. The magnitude of this displacement is ds, showing that: (Eq. 1) This displacement is necessarily a tangent to the curve at s, showing that the unit vector tangent to the curve is: while the outward unit vector normal to the curve is Orthogonality can be verified by showing that the vector dot product is zero. The unit magnitude of these vectors is a consequence of Eq. 1. Using the tangent vector, the angle θ of the tangent to the curve is given by: and The radius of curvature is introduced completely formally (without need for geometric interpretation) as: The derivative of θ can be found from that for sinθ: Now: in which the denominator is unity. With this formula for the derivative of the sine, the radius of curvature becomes: where the equivalence of the forms stems from differentiation of Eq. 1: With these results, the acceleration can be found: as can be verified by taking the dot product with the unit vectors ut(s) and un(s). This result for acceleration is the same as that for circular motion based on the radius ρ. Using this coordinate system in the inertial frame, it is easy to identify the force normal to the trajectory as the centripetal force and that parallel to the trajectory as the tangential force. From a qualitative standpoint, the path can be approximated by an arc of a circle for a limited time, and for the limited time a particular radius of curvature applies, the centrifugal and Euler forces can be analyzed on the basis of circular motion with that radius. This result for acceleration agrees with that found earlier. However, in this approach, the question of the change in radius of curvature with s is handled completely formally, consistent with a geometric interpretation, but not relying upon it, thereby avoiding any questions the image above might suggest about neglecting the variation in ρ. Example: circular motion To illustrate the above formulas, let x, y be given as: Then: which can be recognized as a circular path around the origin with radius α. The position s = 0 corresponds to [α, 0], or 3 o'clock. To use the above formalism, the derivatives are needed: With these results, one can verify that: The unit vectors can also be found: which serve to show that s = 0 is

of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. The procedure which generates this checksum is called a checksum function or checksum algorithm. Depending on its design goals, a good checksum algorithm usually outputs a significantly different value, even for small changes made to the input. This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted. Checksum functions are related to hash functions, fingerprints, randomization functions, and cryptographic hash functions. However, each of those concepts has different applications and therefore different design goals. For instance, a function returning the start of a string can provide a hash appropriate for some applications but will never be a suitable checksum. Checksums are used as cryptographic primitives in larger authentication algorithms. For cryptographic systems with these two specific design goals, see HMAC. Check digits and parity bits are special cases of checksums, appropriate for small blocks of data (such as Social Security numbers, bank account numbers, computer words, single bytes, etc.). Some error-correcting codes are based on special checksums which not only detect common errors but also allow the original data to be recovered in certain cases. Algorithms Parity byte or parity word The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number of bits, and then computes the exclusive or (XOR) of all those words. The result is appended to the message as an extra word. To check the integrity of a message, the receiver computes the exclusive or of all its words, including the checksum; if the result is not a word consisting of zeros, the receiver knows a transmission error occurred. With this checksum, any transmission error which flips a single bit of the message, or an odd number of bits, will be detected as an incorrect checksum. However, an error that affects two bits will not be detected if those bits lie at the same position in two distinct words. Also swapping of two or more words will not be detected. If the affected bits are independently chosen at random, the probability of a two-bit error being undetected is . Sum complement A variant of the previous algorithm is to add all the "words" as unsigned binary numbers, discarding any overflow bits, and append the two's complement of the total as the checksum.

Following the report, Matthew Goldstein, a mathematician and City College graduate who had led CUNY's Baruch College and briefly, Adelphi University, was appointed chancellor. CUNY ended its policy of open admissions to its four-year colleges, raised its admissions standards at its most selective four-year colleges (Baruch, Brooklyn, City, Hunter and Queens), and required new enrollees who needed remediation, to begin their studies at a CUNY open-admissions community college. 2010 onwards CUNY's enrollment of degree-credit students reached 220,727 in 2005 and 262,321 in 2010 as the university broadened its academic offerings. The university added more than 2,000 full-time faculty positions, opened new schools and programs, and expanded the university's fundraising efforts to help pay for them. Fundraising increased from $35 million in 2000 to more than $200 million in 2012. As of Autumn 2013, all CUNY undergraduates are required to take an administration-dictated common core of courses which have been claimed to meet specific "learning outcomes" or standards. Since the courses are accepted university-wide, the administration claims it will be easier for students to transfer course credits between CUNY colleges. It also reduced the number of core courses some CUNY colleges had required, to a level below national norms, particularly in the sciences. The program is the target of several lawsuits by students and faculty, and was the subject of a "no confidence" vote by the faculty, who rejected it by an overwhelming 92% margin. Chancellor Goldstein retired on July 1, 2013, and was replaced on June 1, 2014, by James Milliken, president of the University of Nebraska, and a graduate of the University of Nebraska and New York University School of Law. Milliken retired at the end of the 2018 academic year and moved on to become the Chancellor for the University of Texas system. In 2018, CUNY opened its 25th campus, the CUNY School of Labor and Urban Studies, named after former president Joseph S. Murphy and combining some forms and functions of the Murphy Institute that were housed at the CUNY School of Professional Studies. On February 13, 2019, the Board of Trustees voted to appoint Queens College President Felix V. Matos Rodriguez as the chancellor of the City University of New York. Matos became both the first Latino and minority educator to head the University. He assumed the post May 1. Enrollment and demographics CUNY is the fourth-largest university system in the United States by enrollment, behind the California State University system, the State University of New York (SUNY) system, and the University of California system. More than 271,000-degree-credit students, continuing, and professional education students are enrolled at campuses located in all five New York City boroughs. The university has one of the most diverse student bodies in the United States, with students hailing from around the world, but mostly from New York City. The black, white and Hispanic undergraduate populations each comprise more than a quarter of the student body, and Asian undergraduates make up 18 percent. Fifty-eight percent are female, and 28 percent are 25 or older. In the 2017–2018 award year, 144,380 CUNY students received the Federal Pell Grant. Academics Component institutions Management structure The forerunner of today's City University of New York was governed by the Board of Education of New York City. Members of the Board of Education, chaired by the President of the board, served as ex officio trustees. For the next four decades, the board members continued to serve as ex officio trustees of the College of the City of New York and the city's other municipal college, the Normal College of the City of New York. In 1900, the New York State Legislature created separate boards of trustees for the College of the City of New York and the Normal College, which became Hunter College in 1914. In 1926, the Legislature established the Board of Higher Education of the City of New York, which assumed supervision of both municipal colleges. In 1961, the New York State Legislature established the City University of New York, uniting what had become seven municipal colleges at the time: the City College of New York, Hunter College, Brooklyn College, Queens College, Staten Island Community College, Bronx Community College and Queensborough Community College. In 1979, the CUNY Financing and Governance Act was adopted by the State and the Board of Higher Education became the City University of New York Board of Trustees. Today, the City University is governed by the Board of Trustees composed of 17 members, ten of whom are appointed by the Governor of New York "with the advice and consent of the senate," and five by the Mayor of New York City "with the advice and consent of the senate." The final two trustees are ex officio members. One is the chair of the university's student senate, and the other is non-voting and is the chair of the university's faculty senate. Both the mayoral and gubernatorial appointments to the CUNY Board are required to include at least one resident of each of New York City's five boroughs. Trustees serve seven-year terms, which are renewable for another seven years. The Chancellor is elected by the Board of Trustees, and is the "chief educational and administrative officer" of the City University. The administrative offices are in Midtown Manhattan.

legislation integrated existing institutions and a new graduate school into a coordinated system of higher education for the city, under the control of the "Board of Higher Education of the City of New York", which had been created by New York State legislation in 1926. By 1979, the Board of Higher Education had become the "Board of Trustees of the CUNY". The institutions that were merged to create CUNY were: The Free Academy – Founded in 1847 by Townsend Harris, it was fashioned as "a Free Academy for the purpose of extending the benefits of education gratuitously to persons who have been pupils in the common schools of the city and county of New York." The Free Academy later became the City College of New York. The Female Normal and High School – Founded in 1870, and later renamed the Normal College. It would be renamed again in 1914 to Hunter College. During the early 20th century, Hunter College expanded into the Bronx, with what became Herbert Lehman College. Brooklyn College – Founded in 1930. Queens College – Founded in 1937. Accessible education CUNY has served a diverse student body, especially those excluded from or unable to afford private universities. Its four-year colleges offered a high quality, tuition-free education to the poor, the working class and the immigrants of New York City who met the grade requirements for matriculated status. During the post-World War I era, when some Ivy League universities, such as Yale University, discriminated against Jews, many Jewish academics and intellectuals studied and taught at CUNY. The City College of New York developed a reputation of being "the Harvard of the proletariat." As New York City's population—and public college enrollment—grew during the early 20th century and the city struggled for resources, the municipal colleges slowly began adopting selective tuition, also known as instructional fees, for a handful of courses and programs. During the Great Depression, with funding for the public colleges severely constrained, limits were imposed on the size of the colleges' free Day Session, and tuition was imposed upon students deemed "competent" but not academically qualified for the day program. Most of these "limited matriculation" students enrolled in the Evening Session, and paid tuition. Additionally, as the population of New York grew, CUNY was not able to accommodate the demand for higher education. Higher and higher requirements for admission were imposed; in 1965, a student seeking admission to CUNY needed an average of 92, or A-. This helped to ensure that the student population of CUNY remained largely white and middle-class. Demand in the United States for higher education rapidly grew after World War II, and during the mid-1940s a movement began to create community colleges to provide accessible education and training. In New York City, however, the community-college movement was constrained by many factors including "financial problems, narrow perceptions of responsibility, organizational weaknesses, adverse political factors, and other competing priorities." Community colleges would have drawn from the same city coffers that were funding the senior colleges, and city higher education officials were of the view that the state should finance them. It was not until 1955, under a shared-funding arrangement with New York State, that New York City established its first community college, on Staten Island. Unlike the day college students attending the city's public baccalaureate colleges for free, the community college students had to pay tuition fees under the state-city funding formula. Community college students paid tuition fees for approximately 10 years. Over time, tuition fees for limited-matriculated students became an important source of system revenues. In fall 1957, for example, nearly 36,000 attended Hunter, Brooklyn, Queens and City Colleges for free, but another 24,000 paid tuition fees of up to $300 a year ($ in current dollar terms). Undergraduate tuition and other student fees in 1957 comprised 17 percent of the colleges' $46.8 million in revenues, about $7.74 million ($ in current dollar terms). Three community colleges had been established by early 1961, when New York City's public colleges were codified by the state as a single university with a chancellor at the helm and an infusion of state funds. But the city's slowness in creating the community colleges as demand for college seats was intensifying and had resulted in mounting frustration, particularly on the part of minorities, that college opportunities were not available to them. In 1964, as New York City's Board of Higher Education moved to take full responsibility for the community colleges, city officials extended the senior colleges' free tuition policy to them, a change that was included by Mayor Robert F. Wagner Jr. in his budget plans and took effect with the 1964–65 academic year. Calls for greater access to public higher education from the Black and Puerto Rican communities in New York, especially in Brooklyn, led to the founding of "Community College Number 7," later Medgar Evers College, in 1966–1967. In 1969, a group of Black and Puerto Rican students occupied City College and demanded the racial integration of CUNY, which at the time had an overwhelmingly white student body. Student protests Students at some campuses became increasingly frustrated with the university's and Board of Higher Education's handling of university administration. At Baruch College in 1967, over a thousand students protested the plan to make the college an upper-division school limited to junior, senior, and graduate students. At Brooklyn College in 1968, students attempted a sit-in to demand the admission of more black and Puerto Rican students and additional black studies curriculum. Students at Hunter College also demanded a Black studies program. Members of the SEEK program, which provided academic support for underprepared and underprivileged students, staged a building takeover at Queens College in 1969 to protest the decisions of the program's director, who would later be replaced by a black professor. Puerto Rican students at Bronx Community College filed a report with the New York State Division of Human Rights in 1970, contending that the intellectual level of the college was inferior and discriminatory. Hunter College was crippled for several days by a protest of 2,000 students who had a list of demands focusing on more student representation in college administration. Across CUNY, students boycotted their campuses in 1970 to protest a rise in student fees and other issues, including the proposed (and later implemented) open admissions plan. Like many college campuses in 1970, CUNY faced a number of protests and demonstrations after the Kent State massacre and Cambodian Campaign. The Administrative Council of the City University of New York sent U.S. President Richard Nixon a telegram in 1970 stating, "No nation can long endure the alienation of the best of its young people." Some colleges, including John Jay College of Criminal Justice, historically the "college for cops," held teach-ins in addition to student and faculty protests. Open admissions Under pressure from community activists and CUNY Chancellor Albert Bowker, the Board of Higher Education (BHE) approved an Open Admissions plan in 1966, but it was not scheduled to be fully implemented until 1975. However, in 1969, students and faculty across CUNY participated in rallies, student strikes, and class boycotts demanding an end to CUNY's restrictive admissions policies. CUNY administrators and Mayor John Lindsay expressed support for these demands, and the BHE voted to implement the plan immediately in the fall of 1970. The doors to CUNY were opened wide to all those demanding entrance, assuring all high school graduates entrance to the university without having to fulfill traditional requirements such as exams or grades. This policy was known as open admissions and nearly doubled the number of students enrolling in the CUNY system to 35,000 (compared to 20,000 the year before). With greater numbers came more diversity: Black and Hispanic student enrollment increased threefold. Remedial education, to supplement the training of under-prepared students, became a significant part of CUNY's offerings. Additionally, ethnic and Black Studies programs and centers were instituted on many CUNY campuses, contributing to the growth of similar programs nationwide. However, retention of students in CUNY during this period was low, with two-thirds of students enrolled in the early 1970s leaving within four years without graduating. Robert Kibbee was Chancellor of the City University of New York, the third-largest university in the United States, from 1971 to 1982. Financial crisis of 1976 In fall 1976, during New York City's fiscal crisis, the free tuition policy was discontinued under pressure from the federal government, the financial community that had a role in rescuing the city from bankruptcy, and New York State, which would take over the funding of CUNY's senior colleges. Tuition, which had been in place in the State University of New York system since 1963, was instituted at all CUNY colleges. Meanwhile, CUNY students were added to the state's need-based Tuition Assistance Program (TAP), which had been created to help private colleges. Full-time students who met the income eligibility criteria were permitted to receive TAP, ensuring for the first time that financial hardship would deprive no CUNY student of a college education. Within a few years, the federal government would create its own need-based program, known as Pell Grants, providing the neediest students with a tuition-free college education. Joseph S. Murphy was Chancellor of the City University of New York from 1982 to 1990, when he resigned. CUNY at the time was the third-largest university in the United States, with over 180,000 students. By 2011, nearly six of ten full- time undergraduates qualified for
polynomial-time solution to Π1 would yield a polynomial-time solution to Π2. Similarly, because all NP problems can be reduced to the set, finding an NP-complete problem that can be solved in polynomial time would mean that P = NP. Important open problems P versus NP problem The complexity class P is often seen as a mathematical abstraction modeling those computational tasks that admit an efficient algorithm. This hypothesis is called the Cobham–Edmonds thesis. The complexity class NP, on the other hand, contains many problems that people would like to solve efficiently, but for which no efficient algorithm is known, such as the Boolean satisfiability problem, the Hamiltonian path problem and the vertex cover problem. Since deterministic Turing machines are special non-deterministic Turing machines, it is easily observed that each problem in P is also member of the class NP. The question of whether P equals NP is one of the most important open questions in theoretical computer science because of the wide implications of a solution. If the answer is yes, many important problems can be shown to have more efficient solutions. These include various types of integer programming problems in operations research, many problems in logistics, protein structure prediction in biology, and the ability to find formal proofs of pure mathematics theorems. The P versus NP problem is one of the Millennium Prize Problems proposed by the Clay Mathematics Institute. There is a US$1,000,000 prize for resolving the problem. Problems in NP not known to be in P or NP-complete It was shown by Ladner that if P ≠ NP then there exist problems in NP that are neither in P nor NP-complete. Such problems are called NP-intermediate problems. The graph isomorphism problem, the discrete logarithm problem and the integer factorization problem are examples of problems believed to be NP-intermediate. They are some of the very few NP problems not known to be in P or to be NP-complete. The graph isomorphism problem is the computational problem of determining whether two finite graphs are isomorphic. An important unsolved problem in complexity theory is whether the graph isomorphism problem is in P, NP-complete, or NP-intermediate. The answer is not known, but it is believed that the problem is at least not NP-complete. If graph isomorphism is NP-complete, the polynomial time hierarchy collapses to its second level. Since it is widely believed that the polynomial hierarchy does not collapse to any finite level, it is believed that graph isomorphism is not NP-complete. The best algorithm for this problem, due to László Babai and Eugene Luks has run time for graphs with n vertices, although some recent work by Babai offers some potentially new perspectives on this. The integer factorization problem is the computational problem of determining the prime factorization of a given integer. Phrased as a decision problem, it is the problem of deciding whether the input has a prime factor less than k. No efficient integer factorization algorithm is known, and this fact forms the basis of several modern cryptographic systems, such as the RSA algorithm. The integer factorization problem is in NP and in co-NP (and even in UP and co-UP). If the problem is NP-complete, the polynomial time hierarchy will collapse to its first level (i.e., NP will equal co-NP). The best known algorithm for integer factorization is the general number field sieve, which takes time to factor an odd integer n. However, the best known quantum algorithm for this problem, Shor's algorithm, does run in polynomial time. Unfortunately, this fact doesn't say much about where the problem lies with respect to non-quantum complexity classes. Separations between other complexity classes Many known complexity classes are suspected to be unequal, but this has not been proved. For instance P ⊆ NP ⊆ PP ⊆ PSPACE, but it is possible that P = PSPACE. If P is not equal to NP, then P is not equal to PSPACE either. Since there are many known complexity classes between P and PSPACE, such as RP, BPP, PP, BQP, MA, PH, etc., it is possible that all these complexity classes collapse to one class. Proving that any of these classes are unequal would be a major breakthrough in complexity theory. Along the same lines, co-NP is the class containing the complement problems (i.e. problems with the yes/no answers reversed) of NP problems. It is believed that NP is not equal to co-NP; however, it has not yet been proven. It is clear that if these two complexity classes are not equal then P is not equal to NP, since P=co-P. Thus if P=NP we would have co-P=co-NP whence NP=P=co-P=co-NP. Similarly, it is not known if L (the set of all problems that can be solved in logarithmic space) is strictly contained in P or equal to P. Again, there are many complexity classes between the two, such as NL and NC, and it is not known if they are distinct or equal classes. It is suspected that P and BPP are equal. However, it is currently open if BPP = NEXP. Intractability A problem that can be solved in theory (e.g. given large but finite resources, especially time), but for which in practice any solution takes too many resources to be useful, is known as an . Conversely, a problem that can be solved in practice is called a , literally "a problem that can be handled". The term infeasible (literally "cannot be done") is sometimes used interchangeably with intractable, though this risks confusion with a feasible solution in mathematical optimization. Tractable problems are frequently identified with problems that have polynomial-time solutions (P, PTIME); this is known as the Cobham–Edmonds thesis. Problems that are known to be intractable in this sense include those that are EXPTIME-hard. If NP is not the same as P, then NP-hard problems are also intractable in this sense. However, this identification is inexact: a polynomial-time solution with large degree or large leading coefficient grows quickly, and may be impractical for practical size problems; conversely, an exponential-time solution that grows slowly may be practical on realistic input, or a solution that takes a long time in the worst case may take a short time in most cases or the average case, and thus still be practical. Saying that a problem is not in P does not imply that all large cases of the problem are hard or even that most of them are. For example, the decision problem in Presburger arithmetic has been shown not to be in P, yet algorithms have been written that solve the problem in reasonable times in most cases. Similarly, algorithms can solve the NP-complete knapsack problem over a wide range of sizes in less than quadratic time and SAT solvers routinely handle large instances of the NP-complete Boolean satisfiability problem. To see why exponential-time algorithms are generally unusable in practice, consider a program that makes 2n operations before halting. For small n, say 100, and assuming for the sake of example that the computer does 1012 operations each second, the program would run for about 4 × 1010 years, which is the same order of magnitude as the age of the universe. Even with a much faster computer, the program would only be useful for very small instances and in that sense the intractability of a problem is somewhat independent of technological progress. However, an exponential-time algorithm that takes 1.0001n operations is practical until n gets relatively large. Similarly, a polynomial time algorithm is not always practical. If its running time is, say, n15, it is unreasonable to consider it efficient and it is still useless except on small instances. Indeed, in practice even n3 or n2 algorithms are often impractical on realistic sizes of problems. Continuous complexity theory Continuous complexity theory can refer to complexity theory of problems that involve continuous functions that are approximated by discretizations, as studied in numerical analysis. One approach to complexity theory of numerical analysis is information based complexity. Continuous complexity theory can also refer to complexity theory of the use of analog computation, which uses continuous dynamical systems and differential equations. Control theory can be considered a form of computation and differential equations are used in the modelling of continuous-time and hybrid discrete-continuous-time systems. History An early example of algorithm complexity analysis is the running time analysis of the Euclidean algorithm done by Gabriel Lamé in 1844. Before the actual research explicitly devoted to the complexity of algorithmic problems started off, numerous foundations were laid out by various researchers. Most influential among these was the definition of Turing machines by Alan Turing in 1936, which turned out to be a very robust and flexible simplification of a computer. The beginning of systematic studies in computational complexity is attributed to the seminal 1965 paper "On the Computational Complexity of Algorithms" by Juris Hartmanis and Richard E. Stearns, which laid out the definitions of time complexity and space complexity, and proved the hierarchy theorems. In addition, in 1965 Edmonds suggested to consider a "good" algorithm to be one with running time bounded by a polynomial of the input size. Earlier papers studying problems solvable by Turing machines with specific bounded resources include John Myhill's definition of linear bounded automata (Myhill 1960), Raymond Smullyan's study of rudimentary sets (1961), as well as Hisao Yamada's paper on real-time computations (1962). Somewhat earlier, Boris Trakhtenbrot (1956), a pioneer in the field from the USSR, studied another specific complexity measure. As he remembers: In 1967, Manuel Blum formulated a set of axioms (now
a strip of tape. Turing machines are not intended as a practical computing technology, but rather as a general model of a computing machine—anything from an advanced supercomputer to a mathematician with a pencil and paper. It is believed that if a problem can be solved by an algorithm, there exists a Turing machine that solves the problem. Indeed, this is the statement of the Church–Turing thesis. Furthermore, it is known that everything that can be computed on other models of computation known to us today, such as a RAM machine, Conway's Game of Life, cellular automata, lambda calculus or any programming language can be computed on a Turing machine. Since Turing machines are easy to analyze mathematically, and are believed to be as powerful as any other model of computation, the Turing machine is the most commonly used model in complexity theory. Many types of Turing machines are used to define complexity classes, such as deterministic Turing machines, probabilistic Turing machines, non-deterministic Turing machines, quantum Turing machines, symmetric Turing machines and alternating Turing machines. They are all equally powerful in principle, but when resources (such as time or space) are bounded, some of these may be more powerful than others. A deterministic Turing machine is the most basic Turing machine, which uses a fixed set of rules to determine its future actions. A probabilistic Turing machine is a deterministic Turing machine with an extra supply of random bits. The ability to make probabilistic decisions often helps algorithms solve problems more efficiently. Algorithms that use random bits are called randomized algorithms. A non-deterministic Turing machine is a deterministic Turing machine with an added feature of non-determinism, which allows a Turing machine to have multiple possible future actions from a given state. One way to view non-determinism is that the Turing machine branches into many possible computational paths at each step, and if it solves the problem in any of these branches, it is said to have solved the problem. Clearly, this model is not meant to be a physically realizable model, it is just a theoretically interesting abstract machine that gives rise to particularly interesting complexity classes. For examples, see non-deterministic algorithm. Other machine models Many machine models different from the standard multi-tape Turing machines have been proposed in the literature, for example random-access machines. Perhaps surprisingly, each of these models can be converted to another without providing any extra computational power. The time and memory consumption of these alternate models may vary. What all these models have in common is that the machines operate deterministically. However, some computational problems are easier to analyze in terms of more unusual resources. For example, a non-deterministic Turing machine is a computational model that is allowed to branch out to check many different possibilities at once. The non-deterministic Turing machine has very little to do with how we physically want to compute algorithms, but its branching exactly captures many of the mathematical models we want to analyze, so that non-deterministic time is a very important resource in analyzing computational problems. Complexity measures For a precise definition of what it means to solve a problem using a given amount of time and space, a computational model such as the deterministic Turing machine is used. The time required by a deterministic Turing machine M on input x is the total number of state transitions, or steps, the machine makes before it halts and outputs the answer ("yes" or "no"). A Turing machine M is said to operate within time f(n) if the time required by M on each input of length n is at most f(n). A decision problem A can be solved in time f(n) if there exists a Turing machine operating in time f(n) that solves the problem. Since complexity theory is interested in classifying problems based on their difficulty, one defines sets of problems based on some criteria. For instance, the set of problems solvable within time f(n) on a deterministic Turing machine is then denoted by DTIME(f(n)). Analogous definitions can be made for space requirements. Although time and space are the most well-known complexity resources, any complexity measure can be viewed as a computational resource. Complexity measures are very generally defined by the Blum complexity axioms. Other complexity measures used in complexity theory include communication complexity, circuit complexity, and decision tree complexity. The complexity of an algorithm is often expressed using big O notation. Best, worst and average case complexity The best, worst and average case complexity refer to three different ways of measuring the time complexity (or any other complexity measure) of different inputs of the same size. Since some inputs of size n may be faster to solve than others, we define the following complexities: Best-case complexity: This is the complexity of solving the problem for the best input of size n. Average-case complexity: This is the complexity of solving the problem on an average. This complexity is only defined with respect to a probability distribution over the inputs. For instance, if all inputs of the same size are assumed to be equally likely to appear, the average case complexity can be defined with respect to the uniform distribution over all inputs of size n. Amortized analysis: Amortized analysis considers both the costly and less costly operations together over the whole series of operations of the algorithm. Worst-case complexity: This is the complexity of solving the problem for the worst input of size n. The order from cheap to costly is: Best, average (of discrete uniform distribution), amortized, worst. For example, consider the deterministic sorting algorithm quicksort. This solves the problem of sorting a list of integers that is given as the input. The worst-case is when the pivot is always the largest or smallest value in the list (so the list is never divided). In this case the algorithm takes time O(n2). If we assume that all possible permutations of the input list are equally likely, the average time taken for sorting is O(n log n). The best case occurs when each pivoting divides the list in half, also needing O(n log n) time. Upper and lower bounds on the complexity of problems To classify the computation time (or similar resources, such as space consumption), it is helpful to demonstrate upper and lower bounds on the maximum amount of time required by the most efficient algorithm to solve a given problem. The complexity of an algorithm is usually taken to be its worst-case complexity unless specified otherwise. Analyzing a particular algorithm falls under the field of analysis of algorithms. To show an upper bound T(n) on the time complexity of a problem, one needs to show only that there is a particular algorithm with running time at most T(n). However, proving lower bounds is much more difficult, since lower bounds make a statement about all possible algorithms that solve a given problem. The phrase "all possible algorithms" includes not just the algorithms known today, but any algorithm that might be discovered in the future. To show a lower bound of T(n) for a problem requires showing that no algorithm can have time complexity lower than T(n). Upper and lower bounds are usually stated using the big O notation, which hides constant factors and smaller terms. This makes the bounds independent of the specific details of the computational model used. For instance, if T(n) = 7n2 + 15n + 40, in big O notation one would write T(n) = O(n2). Complexity classes Defining complexity classes A complexity class is a set of problems of related complexity. Simpler complexity classes are defined by the following factors: The type of computational problem: The most commonly used problems are decision problems. However, complexity classes can be defined based on function problems, counting problems, optimization problems, promise problems, etc. The model of computation: The most common model of computation is the deterministic Turing machine, but many complexity classes are based on non-deterministic Turing machines, Boolean circuits, quantum Turing machines, monotone circuits, etc. The resource (or resources) that is being bounded and the bound: These two properties are usually stated together, such as "polynomial time", "logarithmic space", "constant depth", etc. Some complexity classes have complicated definitions that do not fit into this framework. Thus, a typical complexity class has a definition like the following: The set of decision problems solvable by a deterministic Turing machine within time f(n). (This complexity class is known as DTIME(f(n)).) But bounding the computation time above by some concrete function f(n) often yields complexity classes that depend on the chosen machine model. For instance, the language {xx | x is any binary string} can be solved in linear time on a multi-tape Turing machine, but necessarily requires quadratic time in the model of single-tape Turing machines. If we allow polynomial variations in running time, Cobham-Edmonds thesis states that "the time complexities in any two reasonable and general models of computation are polynomially related" . This forms the basis for the complexity class P, which is the set of decision problems solvable by a deterministic Turing machine within polynomial time. The corresponding set of function problems is FP. Important complexity classes Many important complexity classes can be defined by bounding the time or space used by the algorithm. Some important complexity classes of decision problems defined in this manner are the following: The logarithmic-space classes (necessarily) do not take into account the space needed to represent the problem. It turns out that PSPACE = NPSPACE and EXPSPACE = NEXPSPACE by Savitch's theorem. Other important complexity classes include BPP, ZPP and RP, which are defined using probabilistic Turing machines; AC and NC, which are defined using Boolean circuits; and BQP and QMA, which are defined using quantum Turing machines. #P is an important complexity class of counting problems (not decision problems). Classes like IP and AM are defined using Interactive proof systems. ALL is the class of all decision problems. Hierarchy theorems For the complexity classes defined in this way, it is desirable to prove that relaxing the requirements on (say) computation time indeed defines a bigger set of problems. In particular, although DTIME(n) is contained in DTIME(n2), it would be interesting to know if the inclusion is strict. For time and space requirements, the answer to such questions is given by the time and space hierarchy theorems respectively. They are called hierarchy theorems because they induce a proper hierarchy on the classes defined by constraining the respective resources. Thus there are pairs of complexity classes such that one is properly included in the other. Having deduced such proper set inclusions, we can proceed to make quantitative statements about how much more additional time or space is needed in order to increase the number of problems that can be solved. More precisely, the time hierarchy theorem states that . The space hierarchy theorem states that . The time and space hierarchy theorems form the basis for most separation results of complexity classes. For instance, the time hierarchy theorem tells us that P is strictly contained in EXPTIME, and the space hierarchy theorem tells us that L is strictly contained in PSPACE. Reduction Many complexity classes are defined using the concept of a reduction. A reduction is a transformation of one problem into another problem. It captures the informal notion of a problem being at most as difficult as another problem. For instance, if a problem X can be solved using an algorithm for Y, X is no more difficult than Y, and we say that X reduces to Y. There are many different types of reductions, based on the method of reduction, such as Cook reductions, Karp reductions and Levin reductions, and the bound on the complexity of reductions, such as polynomial-time reductions or log-space reductions. The most commonly used reduction is a polynomial-time reduction. This means that the reduction process takes polynomial time. For example, the problem of squaring an integer can be reduced to the problem of multiplying two integers. This means an algorithm for multiplying two integers can be used to square an integer. Indeed, this can be done by giving the same input to both inputs of the multiplication algorithm. Thus we see that squaring is not more difficult than multiplication, since squaring can be reduced to multiplication. This motivates the concept of a problem being hard for a complexity class. A problem X is hard for a class of problems C if every problem in C can be reduced to X. Thus no problem in C is harder than X, since an algorithm for X allows us to solve any problem in C. The notion of hard problems depends on the type of reduction being used. For complexity classes larger than P, polynomial-time reductions are commonly used. In particular, the set of problems that are hard for NP is the set of NP-hard problems. If a problem X is in C and hard for C, then X is said to be complete for C. This means that X is the hardest problem in C. (Since many problems could be equally hard, one might say that X is one of the hardest problems in C.) Thus the class of NP-complete problems contains the most difficult problems in NP, in the sense that they are the ones most likely not to be in P. Because the problem P = NP is not solved, being able to reduce a known NP-complete problem, Π2, to another problem, Π1, would indicate that there is no known polynomial-time solution for Π1. This is because a polynomial-time solution to Π1 would yield a polynomial-time solution to Π2. Similarly, because all NP problems can be reduced to the set, finding an NP-complete problem that can be solved in polynomial time would mean that P = NP. Important open problems P versus NP problem The complexity class P is often seen as a mathematical abstraction modeling those computational tasks that admit an efficient algorithm. This hypothesis is called the Cobham–Edmonds thesis. The complexity class NP, on the other hand, contains many problems that people would like to solve efficiently, but for which no efficient algorithm is known, such as the Boolean satisfiability problem, the Hamiltonian path problem and the vertex cover problem. Since deterministic Turing machines are special non-deterministic Turing machines, it is easily observed that each problem in P is also member of the class NP. The question of whether P equals NP is one of the most important open questions in theoretical computer science because of the wide implications of a solution. If the answer is yes, many important problems can be shown to have more efficient solutions. These include various types of integer programming problems in operations research, many problems in logistics, protein structure prediction in biology, and the ability to find formal proofs of pure mathematics theorems. The P versus NP problem is one of the Millennium

the Siege Perilous, and where the knights see a vision of the Holy Grail and swear to find it. Jousts are often held in a meadow outside the city. Its imprecise geography serves the romances well, as Camelot becomes less a literal place than a powerful symbol of Arthur's court and universe. There is also a Kamaalot featured as the home of Percival's mother in the romance Perlesvaus. In Palamedes and some other works, including the Post-Vulgate cycle, King Arthur's Camelot is eventually razed to the ground by the treacherous King Mark of Cornwall (who had besieged it earlier) in his invasion of Logres after the Battle of Camlann. In the Tavola Ritonda, Camelot falls to ruin after the death of Arthur. From Geoffrey's grand description of Caerleon, Camelot gains its impressive architecture, its many churches and the chivalry and courtesy of its inhabitants. Geoffrey's description in turn drew on an already established tradition in Welsh oral tradition of the grandeur of Arthur's court. The tale Culhwch and Olwen, associated with the Mabinogion and perhaps first written in the 11th century, draws a dramatic picture of Arthur's hall and his many powerful warriors who go from there on great adventures, placing it in Celliwig, an uncertain locale in Cornwall. Although the court at Celliwig is the most prominent in remaining early Welsh manuscripts, the various versions of the Welsh Triads agree in giving Arthur multiple courts, one in each of the areas inhabited by the Celtic Britons: Cornwall, Wales and the Hen Ogledd. This perhaps reflects the influence of widespread oral traditions common by the 9th century which are recorded in various place names and features such as Arthur's Seat, indicating Arthur was a hero known and associated with many locations across Brittonic areas of Britain as well as Brittany. Even at this stage Arthur could not be tied to one location. Many other places are listed as a location where Arthur holds court in the later romances, Carlisle and London perhaps being the most prominent. In the 15th century, the English writer Thomas Malory created the image of Camelot most familiar today in his Le Morte d'Arthur, a work based mostly on the French romances. He firmly identifies Camelot with Winchester in England, an identification that remained popular over the centuries, though it was rejected by Malory's own editor, William Caxton, who preferred a Welsh location. Identifications Arthurian scholar Norris J. Lacy commented that "Camelot, located no where in particular, can be anywhere." The romancers' versions of Camelot draw on earlier traditions of Arthur's fabulous court. The Celliwig of Culhwch and Olwen appears in the Welsh Triads as well; this early Welsh material places Wales' greatest leader outside its national boundaries. Geoffrey's description of Caerleon is probably based on his personal familiarity with the town and its Roman ruins; it is less clear that Caerleon was associated with Arthur before Geoffrey. Several French romances (Perlesvaus, the Didot Perceval attributed to Robert de Boron, and even the early romances of Chrétien such as Erec and Enide and Yvain, the Knight of the Lion) have Arthur hold court at "Carduel in Wales", a northern city based on the real Carlisle. Malory's identification of Camelot as Winchester was probably partially inspired by the latter city's history: it had been the capital of Wessex under Alfred the Great, and boasted the Winchester Round Table, an artifact constructed in the 13th century but widely believed to be the original by Malory's time. Caxton rejected the association, saying Camelot was in Wales and that its ruins could still be seen; this is a likely reference to the Roman ruins at Caerwent. In 1542, John Leland reported the locals around Cadbury Castle, formerly known as Camalet, in Somerset considered it to be the original Camelot. This theory, which was repeated by later antiquaries, is bolstered, or may have derived from, Cadbury's proximity to the River Cam and the villages of Queen Camel and West Camel, and remained popular enough to help inspire a large-scale archaeological dig in the 20th century. These excavations, led by archaeologist Leslie Alcock from 1966 to 1970, were titled "Cadbury-Camelot" and won much media attention. The dig revealed that the site seems to have been occupied as early as the 4th millennium BC and to have been refortified and occupied by a major Brittonic ruler and his war band from . This early medieval settlement continued until around 580. The works were by far the largest known fortification of the period, double the size of comparative caers and with Mediterranean artifacts representing extensive trade and Saxon ones showing possible conquest. The use of the name Camelot and the support of Geoffrey Ashe helped ensure much publicity for the finds, but Alcock himself later grew embarrassed by the supposed Arthurian connection to the site. Following the arguments of David Dumville, Alcock felt the site was too late and too uncertain to be a tenable Camelot. Modern archaeologists follow him in rejecting the name, calling it instead Cadbury Castle hill fort. Despite this, Cadbury remains widely associated with Camelot. The name of the Romano-British town of Camulodunum (modern Colchester) was derived from the Celtic god Camulus. However, it was located well within territory usually thought to have been conquered early in the 5th century by Saxons, so it is unlikely to have been the location of any "true" Camelot, as Arthur is traditionally dated to the late 5th and early 6th century. The town was definitely known as Colchester as early as the Anglo-Saxon Chronicle in 917. Even Colchester Museum argues strongly regarding the historical Arthur: "It would be impossible and inconceivable to link him to the Colchester area, or to Essex more generally," pointing out that the connection between the name Camulodunum and Colchester was unknown until the 18th century. Arthurian scholar Peter Field has suggested that another Camulodunum, a former Roman fort, is a likely location of King Arthur's Camelot and that "Slack, on the outskirts of Huddersfield in West Yorkshire," is where Arthur would have held court. This is because of the name, and also regarding its strategic location: it is but a few miles from the extreme south-west of Hen Ogledd (also making close to North Wales), and would have been a flagship point in staving off attacks to the Celtic kingdoms from the Angles and others. Other places in Britain with names related to "Camel" have also been suggested, such as Camelford in Cornwall, located down the River Camel from where Geoffrey places Camlann, the scene of Arthur's final battle. The
though more usually its precise location is not revealed. Most scholars regard it as being entirely fictional, its unspecified geography being perfect for chivalric romance writers. Nevertheless, arguments about the location of the "real Camelot" have occurred since the 15th century and continue today in popular works and for tourism purposes. Etymology The name's derivation is uncertain. It has numerous different spellings in medieval French Arthurian romances, including Camaalot, Camalot, Chamalot, Camehelot (sometimes read as Camchilot), Camaaloth, Caamalot, Camahaloth, Camaelot, Kamaalot, Kamaaloth, Kaamalot, Kamahaloth, Kameloth, Kamaelot, Kamelot, Kaamelot, Cameloth, and Gamalaot. Arthurian scholar Ernst Brugger suggested that it was a corruption of the site of Arthur's final battle, the Battle of Camlann, in Welsh tradition. Roger Sherman Loomis believed it was derived from Cavalon, a place name that he suggested was a corruption of Avalon (under the influence of the Breton place name Cavallon). He further suggested that Cavalon became Arthur's capital due to confusion with Arthur's other traditional court at Caerleon (Caer Lleon in Welsh). Others have suggested a derivation from the British Iron Age and Romano-British place name Camulodunum, one of the first capitals of Roman Britain and which would have significance in Romano-British culture. Indeed, John Morris, the English historian who specialized in the study of the institutions of the Roman Empire and the history of Sub-Roman Britain, suggested in his book The Age of Arthur that as the descendants of Romanized Britons looked back to a golden age of peace and prosperity under Rome, the name "Camelot" of Arthurian legend may have referred to the capital of Britannia (Camulodunum) in Roman times. It is unclear, however, where Chrétien de Troyes would have encountered the name Camulodunum, or why he would render it as Camaalot, though Urban T. Holmes argued in 1929 that Chrétien had access to Book 2 of Pliny's Natural History, where it is rendered as Camaloduno. Given Chrétien's known tendency to create new stories and characters, being the first to mention the hero Lancelot's love affair with Queen Guinevere for example, the name might also be entirely invented. Medieval literature Arthur's court at Camelot is mentioned for the first time in Chrétien's poem Lancelot, the Knight of the Cart, dating to the 1170s, though it does not appear in all the manuscripts. In the C manuscript (Paris, Bibliothèque Nationale de France, fonds français 794, folio 27r), which might in fact contain the proper reading of Chretien's original text, instead of the place name we find the Old French phrase con lui plot, meaning "as he pleased". The other manuscripts spell the name variously as Chamalot (MS A, f. f. 196r), Camehelot (MS E, f. 1r), Chamaalot (MS G, f. 34f), and Camalot [MS T, f. 41v]; the name is missing, along with the rest of the passage containing it, in MS V [Vatican, Biblioteca Vaticana, Regina 1725]). In the tale, the court is mentioned only in passing and is not described: Nothing in Chrétien's poem suggests the level of importance Camelot would have in later romances. For Chrétien, Arthur's chief court was in Caerleon in Wales; this was the king's primary base in Geoffrey of Monmouth's Historia Regum Britanniae and subsequent literature. Chrétien depicts Arthur, like a typical medieval monarch, holding court at a number of cities and castles. It is not until the 13th-century French prose romances, including the Vulgate and Post-Vulgate cycles, that Camelot began to supersede Caerleon, and even then, many descriptive details applied to Camelot derive from Geoffrey's earlier grand depiction of the Welsh town. Most Arthurian romances of this period produced in English or Welsh did not follow this trend; Camelot was referred to infrequently, and usually in translations from French. One exception is Sir Gawain and the Green Knight, which locates Arthur's court at "Camelot"; however, in Britain, Arthur's court was generally located at Caerleon, or at Carlisle, which is usually identified with the "Carduel" of the French romances. The Lancelot-Grail cycle and the texts it influenced depict the city of Camelot as standing along a river, downstream from Astolat. It is surrounded by plains and forests, and its magnificent cathedral, St. Stephen's, originally established by Josephus, the son of Joseph of Arimathea, is the religious centre for Arthur's Knights of the Round Table. There, Arthur and Guinevere are married and there are the tombs of many kings and knights. In a mighty castle stands the Round Table, created by Merlin and Uther Pendragon; it is here that Galahad conquers the Siege Perilous, and where the knights see a vision of the Holy Grail and swear to find it. Jousts are often held in a meadow outside the city. Its imprecise geography serves the romances well, as Camelot becomes less a literal place than a powerful symbol of Arthur's court and universe. There is also a Kamaalot featured as the home of Percival's mother in the romance Perlesvaus. In Palamedes and some other works, including the Post-Vulgate cycle, King Arthur's Camelot is eventually razed to the ground by the treacherous King Mark of Cornwall (who had besieged it earlier) in his invasion of Logres after the Battle of Camlann. In the Tavola Ritonda, Camelot falls to ruin after the death of Arthur. From Geoffrey's grand description of Caerleon, Camelot gains its impressive architecture, its many churches and the chivalry and courtesy of its inhabitants.

This perhaps reflects the
of September Legion, the Anti-Sandinista Guerrilla Special Forces, and the National Army of Liberation. Initially however, these groups were small and conducted little active raiding into Nicaragua. Anti-Somozistas who had supported the revolution but felt betrayed by the Sandinista government – e.g. Edgar Chamorro, prominent member of the political directorate of the FDN, or Jose Francisco Cardenal, who had briefly served in the Council of State before leaving Nicaragua out of disagreement with the Sandinista government's policies and founding the Nicaraguan Democratic Union (UDN), an opposition group of Nicaraguan exiles in Miami. Another example are the MILPAS (Milicias Populares Anti-Sandinistas), peasant militias led by disillusioned Sandinista veterans from the northern mountains. Founded by Pedro Joaquín González (known as "Dimas"), the Milpistas were also known as (green corn). Even after his death, other MILPAS bands sprouted during 1980–1981. The Milpistas were composed largely of (peasant) highlanders and rural workers. Nicaraguans who had avoided direct involvement in the revolution but opposed the Sandinistas. Main groups The CIA and Argentine intelligence, seeking to unify the anti-Sandinista cause before initiating large-scale aid, persuaded 15 September Legion, the UDN and several former smaller groups to merge in September 1981 as the Nicaraguan Democratic Force (Fuerza Democrática Nicaragüense, FDN). Although the FDN had its roots in two groups made up of former National Guardsmen (of the Somoza regime), its joint political directorate was led by businessman and former anti-Somoza activist Adolfo Calero Portocarrero. Edgar Chamorro later stated that there was strong opposition within the UDN against working with the Guardsmen and that the merging only took place because of insistence by the CIA. Based in Honduras, Nicaragua's northern neighbor, under the command of former National Guard Colonel Enrique Bermúdez, the new FDN commenced to draw in other smaller insurgent forces in the north. Largely financed, trained, equipped, armed and organized by the U.S., it emerged as the largest and most active contra group. In April 1982, Edén Pastora (Comandante Cero), one of the heroes in the fight against Somoza, organized the Sandinista Revolutionary Front (FRS) – embedded in the Democratic Revolutionary Alliance (ARDE) – and declared war on the Sandinista government. Himself a former Sandinista who had held several high posts in the government, he had resigned abruptly in 1981 and defected, believing that the newly found power had corrupted the Sandinista's original ideas. A popular and charismatic leader, Pastora initially saw his group develop quickly. He confined himself to operate in the southern part of Nicaragua; after a press conference he was holding on 30 May 1984 was bombed, he "voluntarily withdrew" from the contra struggle. A third force, Misurasata, appeared among the Miskito, Sumo and Rama Amerindian peoples of Nicaragua's Atlantic coast, who in December 1981 found themselves in conflict with the authorities following the government's efforts to nationalize indigenous lands. In the course of this conflict, forced removal of at least 10,000 indigenous people to relocation centers in the interior of the country and subsequent burning of some villages took place. The Misurasata movement split in 1983, with the breakaway Misura group of Stedman Fagoth Muller allying itself more closely with the FDN, and the rest accommodating themselves with the Sandinistas: On 8 December 1984 a ceasefire agreement known as the Bogota Accord was signed by Misurasata and the Nicaraguan government. A subsequent autonomy statute in September 1987 largely defused Miskito resistance. Unity efforts U.S. officials were active in attempting to unite the Contra groups. In June 1985 most of the groups reorganized as the United Nicaraguan Opposition (UNO), under the leadership of Adolfo Calero, Arturo Cruz and Alfonso Robelo, all originally supporters of the anti-Somoza revolution. After UNO's dissolution early in 1987, the Nicaraguan Resistance (RN) was organized along similar lines in May.

However, the evidence of a very close relationship between the contras and the United States was considered overwhelming and incontrovertible. The U.S. played a very large role in financing, training, arming, and advising the contras over a long period, and the contras only became capable of carrying out significant military operations as a result of this support. Political background The US government viewed the leftist Sandinistas as a threat to economic interests of American corporations in Nicaragua and to national security. US President Ronald Reagan stated in 1983 that "The defense of [the USA's] southern frontier" was at stake. "In spite of the Sandinista victory being declared fair, the United States continued to oppose the left-wing Nicaraguan government." and opposed its ties to Cuba and the Soviet Union. Ronald Reagan, who had assumed the American presidency in January 1981, accused the Sandinistas of importing Cuban-style socialism and aiding leftist guerrillas in El Salvador. The Reagan administration continued to view the Sandinistas as undemocratic despite the 1984 Nicaraguan elections being generally declared fair by foreign observers. Throughout the 1980s the Sandinista government was regarded as "Partly Free" by Freedom House, an organization financed by the U.S. government. On 4 January 1982, Reagan signed the top secret National Security Decision Directive 17 (NSDD-17), giving the CIA the authority to recruit and support the contras with $19 million in military aid. The effort to support the contras was one component of the Reagan Doctrine, which called for providing military support to movements opposing Soviet-supported, communist governments. By December 1981, however, the United States had already begun to support armed opponents of the Sandinista government. From the beginning, the CIA was in charge. The arming, clothing, feeding and supervision of the contras became the most ambitious paramilitary and political action operation mounted by the agency in nearly a decade. In the fiscal year 1984, the U.S. Congress approved $24 million in contra aid. However, since the contras failed to win widespread popular support or military victories within Nicaragua, opinion polls indicated that a majority of the U.S. public was not supportive of the contras, the Reagan administration lost much of its support regarding its contra policy within Congress after disclosure of CIA mining of Nicaraguan ports, and a report of the Bureau of Intelligence and Research commissioned by the State Department found Reagan's allegations about Soviet influence in Nicaragua "exaggerated", Congress cut off all funds for the contras in 1985 by the third Boland Amendment. The Boland Amendment had first been passed by Congress in December 1982. At this time, it only outlawed U.S. assistance to the contras "for the purpose of overthrowing the Nicaraguan government", while allowing assistance for other purposes. In October 1984, it was amended to forbid action by not only the Defense Department and the Central Intelligence Agency but all U.S. government agencies. Nevertheless, the case for support of the contras continued to be made in Washington, D.C., by both the Reagan administration and the Heritage Foundation, which argued that support for the contras would counter Soviet influence in Nicaragua. On 1 May 1985 President Reagan announced that his administration perceived Nicaragua to be "an unusual and extraordinary threat to the national security and foreign policy of the United States", and declared a "national emergency" and a trade embargo against Nicaragua to "deal with that threat". It "is now a given; it is true", the Washington Post declared in 1986, "the Sandinistas are communists of the Cuban or Soviet school"; that "The Reagan administration is right to take Nicaragua as a serious menace—to civil peace and democracy in Nicaragua and to the stability and security of the region"; that we must "fit Nicaragua back into a Central American mode" and "turn Nicaragua back toward democracy", and with the "Latin American democracies" "demand reasonable conduct by regional standard." Soon after the embargo was established, Managua re-declared "a policy of nonalignment" and sought the aid of Western Europe, who were opposed to U.S. policy, to escape dependency on the Soviet Union. Since 1981 U.S. pressures had curtailed Western credit to and trade with Nicaragua, forcing the government to rely almost totally on the Eastern bloc for credit, other aid, and trade by 1985. The government's program included increased wages, subsidized food prices, and expanded health, welfare, and education services. And though it nationalized Somoza's former properties, it preserved a private sector that accounted for between 50 and 60 percent of GDP. Atrocities The United States began to support Contra activities against the Sandinista government by December 1981, with the CIA at the forefront of operations. The CIA supplied the funds and the equipment, coordinated training programs, and provided intelligence and target lists. While the Contras had little military successes, they did prove adept at carrying out CIA guerrilla warfare strategies from training manuals which advised them to incite mob violence, "neutralize" civilian leaders and government officials and attack "soft targets"—including schools, health clinics and cooperatives. The agency added to the Contras' sabotage efforts by blowing up refineries and pipelines, and mining ports. Finally, according to former Contra leader Edgar Chamorro, CIA trainers also gave Contra soldiers large knives. "A commando knife [was given], and our people, everybody wanted to have a knife like that, to kill people, to cut their throats". In 1985 Newsweek published a series of photos taken by Frank Wohl, a conservative student admirer traveling with the Contras, entitled "Execution in the Jungle": The victim dug his own grave, scooping the dirt out with his hands ... He crossed himself. Then a contra executioner knelt and rammed a k-bar knife into his throat. A second enforcer stabbed at his jugular, then his abdomen. When the corpse was finally still, the contras threw dirt over the shallow grave—and walked away."Nicaraguan Contra Atrocities" West 57th, 1987, Video: 11:20 The CIA officer in charge of the covert war, Duane "Dewey" Clarridge, admitted to the House Intelligence Committee staff in a secret briefing in 1984 that the Contras were routinely murdering "civilians and Sandinista officials in the provinces, as well as heads of cooperatives, nurses, doctors and judges". But he claimed that this did not violate President Reagan's executive order prohibiting assassinations because the agency defined it as just 'killing'. "After all, this is war—a paramilitary operation", Clarridge said in conclusion. Edgar Chamorro explained the rationale behind this to
to the Contras, the Reagan administration sought to arrange funding and military supplies by means of third countries and private sources. Between 1984 and 1986, $34 million from third countries and $2.7 million from private sources were raised this way. The secret contra assistance was run by the National Security Council, with officer Lt. Col. Oliver North in charge. With the third-party funds, North created an organization called The Enterprise, which served as the secret arm of the NSC staff and had its own airplanes, pilots, airfield, ship, operatives, and secret Swiss bank accounts. It also received assistance from personnel from other government agencies, especially from CIA personnel in Central America. This operation functioned, however, without any of the accountability required of U.S. government activities. The Enterprise's efforts culminated in the Iran–Contra Affair of 1986–1987, which facilitated contra funding through the proceeds of arms sales to Iran. According to the London Spectator, U.S. journalists in Central America had long known that the CIA was flying in supplies to the Contras inside Nicaragua before the scandal broke. No journalist paid it any attention until the alleged CIA supply man, Eugene Hasenfus, was shot down and captured by the Nicaraguan army. Similarly, reporters neglected to investigate many leads indicating that Oliver North was running the Contra operation from his office in the National Security Council. According to the National Security Archive, Oliver North had been in contact with Manuel Noriega, the military leader of Panama later convicted on drug charges, whom he personally met. The issue of drug money and its importance in funding the Nicaraguan conflict was the subject of various reports and publications. The contras were funded by drug trafficking, of which the United States was aware. Senator John Kerry's 1988 Committee on Foreign Relations report on Contra drug links concluded that "senior U.S. policy makers were not immune to the idea that drug money was a perfect solution to the Contras' funding problems". The Reagan administration's support for the Contras continued to stir controversy well into the 1990s. In August 1996, San Jose Mercury News reporter Gary Webb published a series titled Dark Alliance, alleging that the contras contributed to the rise of crack cocaine in California. Gary Webb's career as a journalist was subsequently discredited by the leading U.S. papers, The New York Times, the Washington Post, and the Los Angeles Times. An internal CIA report, entitled, "Managing a Nightmare", shows the agency used "a ground base of already productive relations with journalists" to help counter what it called "a genuine public relations crisis." In the 1980s, Douglas Farah worked as a journalist, covering the civil wars in Central America for the Washington Post. According to Farah, while it was common knowledge that the Contras were involved in cocaine trafficking, the editors of the Washington Post refused to take it seriously: If you're talking about our intelligence community tolerating—if not promoting—drugs to pay for black ops, it's rather an uncomfortable thing to do when you're an establishment paper like the Post. If you were going to be directly rubbing up against the government, they wanted it more solid than it could probably ever be done. An investigation by the United States Department of Justice also stated that their "review did not substantiate the main allegations stated and implied in the Mercury News articles." Regarding the specific charges towards the CIA, the DOJ wrote "the implication that the drug trafficking by the individuals discussed in the Mercury News articles was connected to the CIA was also not supported by the facts." The CIA also investigated and rejected the allegations. Propaganda During the time the US Congress blocked funding for the contras, the Reagan government engaged in a campaign to alter public opinion and change the vote in Congress on contra aid. For this purpose, the NSC established an interagency working group, which in turn coordinated the Office of Public Diplomacy for Latin America and the Caribbean (managed by Otto Reich), which conducted the campaign. The S/LPD produced and widely disseminated a variety of pro-contra publications, arranged speeches and press conferences. It also disseminated "white propaganda"—pro-contra newspaper articles by paid consultants who did not disclose their connection to the Reagan administration. On top of that, Oliver North helped Carl Channell's tax-exempt organization, the National Endowment for the Preservation of Liberty, to raise $10 million, by arranging numerous briefings for groups of potential contributors at the premises of the White House and by facilitating private visits and photo sessions with President Reagan for major contributors. Channell in turn, used part of that money to run a series of television advertisements directed at home districts of Congressmen considered swing votes on contra aid. Out of the $10 million raised, more than $1 million was spent on pro-contra publicity. International Court of Justice ruling In 1984 the Sandinista government filed a suit in the International Court of Justice (ICJ) against the United States (Nicaragua v. United States), which resulted in a 1986 judgment against the United States. The ICJ held that the U.S. had violated international law by supporting the contras in their rebellion against the Nicaraguan government and by mining Nicaragua's harbors. Regarding the alleged human rights violations by the contras, however, the ICJ took the view that the United States could be held accountable for them only if it would have been proven that the U.S. had effective control of the contra operations resulting in these alleged violations. Nevertheless, the ICJ found that the U.S. encouraged acts contrary to general principles of humanitarian law by producing the manual Psychological Operations in Guerrilla Warfare (Operaciones sicológicas en guerra de guerrillas) and disseminating it to the contras. The manual, amongst other things, advised on how to rationalize killings of civilians and recommended to hire professional killers for specific selective tasks. The United States, which did not participate in the merits phase of the proceedings, maintained that the ICJ's power did not supersede the Constitution of the United States and argued that the court did not seriously consider the Nicaraguan role in El Salvador, while it accused Nicaragua of actively supporting armed groups there, specifically in the form of supply of arms. The ICJ had found that evidence of a responsibility of the Nicaraguan government in this matter was insufficient. The U.S. argument was affirmed, however, by the dissenting opinion of ICJ member U.S. Judge Schwebel, who concluded that in supporting the contras, the United States acted lawfully in collective self-defence in El Salvador's support. The U.S. blocked enforcement of the ICJ judgment by the United Nations Security Council and thereby prevented Nicaragua from obtaining any actual compensation. The Nicaraguan government finally withdrew the complaint from the court in September 1992 (under the later, post-FSLN, government of Violeta Chamorro), following a repeal of the law requiring the country to seek compensation. Human rights violations Americas Watch, which subsequently became part of Human Rights Watch, accused the Contras of: targeting health care clinics and health care workers for assassination kidnapping civilians torturing civilians executing civilians, including children, who were captured in combat raping women indiscriminately attacking civilians and civilian houses seizing civilian property burning civilian houses in captured towns. Human Rights Watch released a report on the situation in 1989, which stated: "[The] contras were major and systematic violators of the most basic standards of the laws of armed conflict, including by launching indiscriminate attacks on civilians, selectively murdering non-combatants, and mistreating prisoners." In his affidavit to the World Court, former contra Edgar Chamorro testified that "The CIA did not discourage such tactics. To the contrary, the Agency severely criticized me when I admitted to the press that the FDN had regularly kidnapped and executed agrarian reform workers and civilians. We were told that the only way to defeat the Sandinistas was to ...kill, kidnap, rob and torture". Contra leader Adolfo Calero denied that his forces deliberately targeted civilians: "What they call a cooperative is also a troop concentration full of armed people. We are not killing civilians. We are fighting armed people and returning fire when fire is directed at us." Controversy U.S. news media published several articles accusing Americas Watch and other bodies of ideological bias and unreliable reporting. It alleged that Americas Watch gave too much credence to alleged Contra abuses and systematically tried to discredit Nicaraguan human rights groups such as the Permanent Commission on Human Rights, which blamed the major human rights abuses on the Contras. In 1985, The Wall Street Journal reported: Human Rights Watch, the umbrella organization of Americas Watch, replied to these allegations: "Almost invariably, U.S. pronouncements on human rights exaggerated and distorted the real human rights violations of the Sandinista regime, and exculpated those of the U.S.-supported insurgents, known as the contras ... The Bush administration is responsible for these abuses, not only because the contras are, for all practical purposes, a U.S. force, but also because the Bush administration has continued to minimize and deny these violations, and has refused to investigate them seriously." Military successes and election of Violeta Chamorro By 1986 the contras were besieged by charges of corruption, human-rights abuses, and military ineptitude. A much-vaunted early 1986 offensive never materialized, and Contra forces were largely reduced to isolated acts of terrorism. In October 1987, however, the contras staged a successful attack in southern Nicaragua. Then on 21 December 1987, the FDN launched attacks at Bonanza, Siuna, and Rosita in Zelaya province, resulting in heavy fighting. ARDE Frente Sur attacked at El Almendro and along the Rama road. These large-scale raids mainly became possible as the contras were able to use U.S.-provided Redeye missiles against Sandinista Mi-24 helicopter gunships, which had been supplied by the Soviets. Nevertheless, the Contras remained tenuously encamped within Honduras and were not able to hold Nicaraguan territory. There were isolated protests among the population against the draft implemented by the Sandinista government, which even resulted in full-blown street clashes in Masaya in 1988. However, a June 1988 survey in Managua showed the Sandinista government still enjoyed strong support but that support had declined since 1984. Three times as many people identified with the Sandinistas (28%) than with all the opposition
an American biotechnologist and businessman. He is known for leading the first draft sequence of the human genome and assembled the first team to transfect a cell with a synthetic chromosome. Venter founded Celera Genomics, the Institute for Genomic Research (TIGR) and the J. Craig Venter Institute (JCVI), where he currently serves as CEO. He was the co-founder of Human Longevity Inc. and Synthetic Genomics. He was listed on Time magazine's 2007 and 2008 Time 100 list of the most influential people in the world. In 2010, the British magazine New Statesman listed Craig Venter at 14th in the list of "The World's 50 Most Influential Figures 2010". In 2012, Venter was honored with Dan David Prize for his contribution to genome research. He was elected to the American Philosophical Society in 2013. He is a member of the USA Science and Engineering Festival's Advisory Board. Early life and education Venter was born in Salt Lake City, Utah, the son of Elizabeth and John Venter. In his youth, he did not take his education seriously, preferring to spend his time on the water in boats or surfing. According to his biography, A Life Decoded, he was said never to be a terribly engaged student, having Cs and Ds on his eighth-grade report cards. He graduated from Mills High School in Millbrae, California. Although he opposed the Vietnam War, Venter was drafted and enlisted in the United States Navy where he worked as a hospital corpsman in the intensive-care ward of a field hospital. He served from 1967 to 1968 at the Naval Support Activity Danang in Vietnam. While in Vietnam, he attempted suicide by swimming out to sea, but changed his mind more than a mile out. Being confronted with severely injured and dying marines on a daily basis instilled in him a desire to study medicine, although he later switched to biomedical research. Venter began his college education in 1969 at a community college, College of San Mateo in California, and later transferred to the University of California, San Diego, where he studied under biochemist Nathan O. Kaplan. He received a Bachelor of Science in biochemistry in 1972 and a Doctor of Philosophy in physiology and pharmacology in 1975 from UCSD. Career After working as an associate professor, and later as full professor, at the State University of New York at Buffalo, he joined the National Institutes of Health in 1984. EST controversy While an employee of the NIH, Venter learned how to identify mRNA and began to learn more about those expressed in the human brain. The short cDNA sequence fragments he was interested in are called expressed sequence tags, or ESTs. The NIH Office of Technology Transfer and Venter decided to take the ESTs discovered by others in an attempt to patent the genes identified based on studies of mRNA expression in the human brain. When Venter disclosed this strategy during a Congressional hearing, a firestorm of controversy erupted. The NIH later stopped the effort and abandoned the patent applications it had filed, following public outcry. Human Genome Project Venter was passionate about the power of genomics to transform healthcare radically. Venter believed that shotgun sequencing was the fastest and most effective way to get useful human genome data. The method was rejected by the Human Genome Project however, since some geneticists felt it would not be accurate enough for a genome as complicated as that of humans, that it would be logistically more difficult, and that it would cost significantly more. Venter viewed the slow pace of progress in the Human Genome project as an opportunity to continue his interest in patenting genes, so he sought funding from the private sector to start Celera Genomics. The company planned to profit from their work by creating genomic data to which users could subscribe for a fee. The goal consequently put pressure on the public genome program and spurred several groups to redouble their efforts to produce the full sequence. Venter's effort won him renown as he and his team at Celera Corporation shared credit for sequencing the first draft human genome with the publicly funded Human Genome Project. In 2000, Venter and Francis Collins of the National Institutes of Health and U.S. Public Genome Project jointly made the announcement of the mapping of the human genome, a full three years ahead of the expected end of the Public Genome Program. The announcement was made along with U.S. President Bill Clinton, and UK Prime Minister Tony Blair. Venter and Collins thus shared an award for "Biography of the Year" from A&E Network. On 15 February 2001, the Human Genome Project consortium published the first Human Genome in the journal Nature, followed one day later by a Celera publication in Science. Despite some claims that shotgun sequencing was in some ways less accurate than the clone-by-clone method chosen by the Human Genome Project, the technique became widely accepted by the scientific community. Venter was fired by Celera in early 2002. According to his biography, Venter was fired because of a conflict with the main investor, Tony White, specifically barring him from attending the White House ceremony celebrating the achievement of sequencing the human genome. Global Ocean Sampling Expedition The Global Ocean Sampling Expedition (GOS) is an ocean exploration genome project with the goal of assessing the genetic diversity in marine microbial communities and to understand their role in nature's fundamental processes. Begun as a Sargasso Sea pilot sampling project in August 2003, Venter announced the full Expedition on 4 March 2004. The project, which used Venter's personal yacht, Sorcerer II, started in Halifax, Canada, circumnavigated the globe and returned to the U.S. in January 2006. Synthetic Genomics In June 2005, Venter co-founded Synthetic Genomics, a firm dedicated to using modified microorganisms to produce clean fuels and biochemicals. In July 2009, ExxonMobil announced a $600 million collaboration with Synthetic Genomics to research and develop next-generation biofuels. Venter continues to work on the creation of engineered diatomic microalgae for the production of biofuels. Venter is seeking to patent the first partially synthetic species possibly to be named Mycoplasma laboratorium. There is speculation that this line of research could lead to producing bacteria that have been engineered to perform specific reactions, for example, produce fuels, make medicines, combat global warming, and so on. In May 2010, a team of scientists led by Venter became the first to create successfully what was described as "synthetic life". This was done by synthesizing a very long DNA molecule containing an entire bacterium genome, and introducing this into another cell, analogous to the accomplishment of Eckard Wimmer's group, who synthesized and ligated an RNA virus genome and "booted" it in cell lysate. The single-celled organism contains four "watermarks" written into its DNA to identify it as synthetic and to help trace its descendants. The watermarks include Code table for entire alphabet with punctuations Names of 46 contributing scientists Three quotations The secret email address for the cell. On March 25, 2016 Venter reported the creation of Syn 3.0, a synthetic genome having the fewest genes of any freely living organism (473 genes). Their aim was
genome having the fewest genes of any freely living organism (473 genes). Their aim was to strip away all nonessential genes, leaving only the minimal set necessary to support life. This stripped-down, fast reproducing cell is expected to be a valuable tool for researchers in the field. In August 2018, Venter retired as chairman of the board, saying he wanted to focus on his work at the J. Craig Venter Institute. He will remain as a scientific advisor to the board. J. Craig Venter Institute Venter is currently the chief executive officer of the J. Craig Venter Institute, a nonprofit which conducts research in synthetic biology. Venter founded the organization in 2006. It has facilities in La Jolla and in Rockville, Maryland and employs over 200 people. Individual human genome On September 4, 2007, a team led by Sam Levy published one of the first genomes of an individual human—Venter's own DNA sequence. Some of the sequences in Venter's genome are associated with wet earwax, increased risk of antisocial behavior, Alzheimer's and cardiovascular diseases. This publication was especially interesting because it attempted to separate the two haplotypes (the two copies of each chromosome), although it only accomplished this in a limited way. The genome as published only had 3 billion bases, rather than the full 6 billion that would compose a fully diploid sequence. Another 10 years passed before the first haplotype-resolved human genomes began to appear. The Human Reference Genome Browser is a web application for the navigation and analysis of Venter's recently published genome. The HuRef database consists of approximately 32 million DNA reads sequenced using microfluidic Sanger sequencing, assembled into 4,528 scaffolds and 4.1 million DNA variations identified by genome analysis. These variants include single-nucleotide polymorphisms (SNPs), block substitutions, short and large indels, and structural variations like insertions, deletions, inversions and copy number changes. The browser enables scientists to navigate the HuRef genome assembly and sequence variations, and to compare it with the NCBI human build 36 assembly in the context of the NCBI and Ensembl annotations. The browser provides a comparative view between NCBI and HuRef consensus sequences, the sequence multi-alignment of the HuRef assembly, Ensembl and dbSNP annotations, HuRef variants, and the underlying variant evidence and functional analysis. The interface also represents the haplotype blocks from which diploid genome sequence can be inferred and the relation of variants to gene annotations. The display of variants and gene annotations are linked to external public resources including dbSNP, Ensembl, Online Mendelian Inheritance in Man (OMIM) and Gene Ontology (GO). Users can search the HuRef genome using HUGO gene names, Ensembl and dbSNP identifiers, HuRef contig or scaffold locations, or NCBI chromosome locations. Users can then easily and quickly browse any genomic region via the simple and intuitive pan and zoom controls; furthermore, data relevant to specific loci can be exported for further analysis. Human Longevity, Inc. On March 4, 2014 Venter and co-founders Peter Diamandis and Robert Hariri announced the formation of Human Longevity, Inc., a company focused on extending the healthy, "high performance" human lifespan. At the time of the announcement the company had already raised $70 million in venture financing, which was expected to last 18 months. Venter served as the chairman and chief executive officer (CEO) until May 2018, when he retired. The company said that it plans to sequence 40,000 genomes per year, with an initial focus on cancer genomes and the genomes of cancer patients. Human Longevity filed a lawsuit in 2018 against Venter, accusing him of stealing trade secrets. Allegations were made stating that Venter had departed with his company computer that contained valuable information that could be used to start a competing business. The lawsuit was ultimately dismissed by a California judge on the basis that Human Longevity were unable to present a case that met the legal threshold required for a company, or individual, to sue when its trade secrets have been stolen. Human Longevity's mission is to extend healthy human lifespan by the use of high-resolution big data diagnostics from genomics, metabolomics, microbiomics, and proteomics, and the use of stem cell therapy. Published books Venter is the author of two books, the first of which was an autobiography titled A Life Decoded. Venter's second book was titled Life at the Speed of Light in which he announced his theory that this is the generation in which there appears to be a dovetailing of the two previously diverse fields of science represented by computer programming and the genetic programming of life by DNA sequencing. He was applauded for his position on this by futurist Ray Kurzweil. Personal life After a brief marriage to Barbara Rae-Venter, with whom he had a son, Christopher, he married Claire M. Fraser remaining married to her until 2005. In late 2008 he married Heather Kowalski. They live in the La Jolla neighborhood of San Diego, CA. Venter is an atheist. Venter considered that his behavior in his adolescence was indicative of attention deficit hyperactivity disorder (ADHD), and later found ADHD-linked genetic variants in his own DNA. In popular culture Venter has been the subject of articles in several magazines, including Wired, The Economist, Australian science magazine Cosmos, and The Atlantic. Venter appears in the two-hour 2001 NOVA special, "Cracking the code of life". On May 16, 2004, Venter gave the commencement speech at Boston University. On December 4, 2007, Venter gave the Dimbleby lecture for the BBC in London. Venter delivered the 2008 convocation speech for Faculty of Science honours and specialization students at the University of Alberta. In February 2008, he gave a speech about his current work at the TED conference. Venter was featured in Time magazine's "The Top 10 Everything of 2008" article. Number three in 2008's Top 10 Scientific Discoveries was a piece outlining his work stitching together the 582,000 base pairs necessary to invent the genetic information for a whole new bacterium. On May 20, 2010, Venter announced the creation of first self-replicating semi-synthetic bacterial cell. In the June 2011 issue of Men's Journal, Venter was featured as the "Survival Skills" celebrity of the month. He shared various anecdotes and advice, including stories of his time in Vietnam, as well as mentioning a bout with melanoma on his back, which subsequently resulted in his "giving a pound of flesh" to surgery. In May 2011, Venter was the commencement speaker at the 157th commencement of Syracuse University.

days later after a heart attack. Theory Rogers' theory of the self is considered to be humanistic, existential, and phenomenological. His theory is based directly on the "phenomenal field" personality theory of Combs and Snygg (1949). Rogers' elaboration of his own theory is extensive. He wrote 16 books and many more journal articles describing it. Prochaska and Norcross (2003) states Rogers "consistently stood for an empirical evaluation of psychotherapy. He and his followers have demonstrated a humanistic approach to conducting therapy and a scientific approach to evaluating therapy need not be incompatible." Nineteen propositions His theory (as of 1951) was based on 19 propositions: All individuals (organisms) exist in a continually changing world of experience (phenomenal field) of which they are the center. The organism reacts to the field as it is experienced and perceived. This perceptual field is "reality" for the individual. The organism reacts as an organized whole to this phenomenal field. A portion of the total perceptual field gradually becomes differentiated as the self. As a result of interaction with the environment, and particularly as a result of evaluative interaction with others, the structure of the self is formed—an organized, fluid but consistent conceptual pattern of perceptions of characteristics and relationships of the "I" or the "me", together with values attached to these concepts. The organism has one basic tendency and striving—to actualize, maintain and enhance the experiencing organism. The best vantage point for understanding behavior is from the internal frame of reference of the individual. Behavior is basically the goal-directed attempt of the organism to satisfy its needs as experienced, in the field as perceived. Emotion accompanies, and in general facilitates, such goal directed behavior, the kind of emotion being related to the perceived significance of the behavior for the maintenance and enhancement of the organism. The values attached to experiences, and the values that are a part of the self-structure, in some instances, are values experienced directly by the organism, and in some instances are values introjected or taken over from others, but perceived in distorted fashion, as if they had been experienced directly. As experiences occur in the life of the individual, they are either, a) symbolized, perceived and organized into some relation to the self, b) ignored because there is no perceived relationship to the self structure, c) denied symbolization or given distorted symbolization because the experience is inconsistent with the structure of the self. Most of the ways of behaving that are adopted by the organism are those that are consistent with the concept of self. In some instances, behavior may be brought about by organic experiences and needs which have not been symbolized. Such behavior may be inconsistent with the structure of the self but in such instances the behavior is not "owned" by the individual. Psychological adjustment exists when the concept of the self is such that all the sensory and visceral experiences of the organism are, or may be, assimilated on a symbolic level into a consistent relationship with the concept of self. Psychological maladjustment exists when the organism denies awareness of significant sensory and visceral experiences, which consequently are not symbolized and organized into the gestalt of the self structure. When this situation exists, there is a basic or potential psychological tension. Any experience which is inconsistent with the organization of the structure of the self may be perceived as a threat, and the more of these perceptions there are, the more rigidly the self structure is organized to maintain itself. Under certain conditions, involving primarily complete absence of threat to the self structure, experiences which are inconsistent with it may be perceived and examined, and the structure of self revised to assimilate and include such experiences. When the individual perceives and accepts into one consistent and integrated system all his sensory and visceral experiences, then he is necessarily more understanding of others and is more accepting of others as separate individuals. As the individual perceives and accepts into his self structure more of his organic experiences, he finds that he is replacing his present value system—based extensively on introjections which have been distortedly symbolized—with a continuing organismic valuing process. In relation to No. 17, Rogers is known for practicing "unconditional positive regard", which is defined as accepting a person "without negative judgment of .... [a person's] basic worth". Development of the personality With regard to development, Rogers described principles rather than stages. The main issue is the development of a self-concept and the progress from an undifferentiated self to being fully differentiated. In the development of the self-concept, he saw conditional and unconditional positive regard as key. Those raised in an environment of unconditional positive regard have the opportunity to fully actualize themselves. Those raised in an environment of conditional positive regard feel worthy only if they match conditions (what Rogers describes as conditions of worth) that have been laid down for them by others. Fully functioning person Optimal development, as referred to in proposition 14, results in a certain process rather than static state. He describes this as the good life, where the organism continually aims to fulfill its full potential. He listed the characteristics of a fully functioning person (Rogers 1961): A growing openness to experience – they move away from defensiveness and have no need for subception (a perceptual defense that involves unconsciously applying strategies to prevent a troubling stimulus from entering consciousness). An increasingly existential lifestyle – living each moment fully – not distorting the moment to fit personality or self-concept but allowing personality and self-concept to emanate from the experience. This results in excitement, daring, adaptability, tolerance, spontaneity, and a lack of rigidity and suggests a foundation of trust. "To open one's spirit to what is going on now, and discover in that present process whatever structure it appears to have" (Rogers 1961) Increasing organismic trust – they trust their own judgment and their ability to choose behavior that is appropriate for each moment. They do not rely on existing codes and social norms but trust that as they are open to experiences they will be able to trust their own sense of right and wrong. Freedom of choice – not being shackled by the restrictions that influence an incongruent individual, they are able to make a wider range of choices more fluently. They believe that they play a role in determining their own behavior and so feel responsible for their own behavior. Creativity – it follows that they will feel more free to be creative. They will also be more creative in the way they adapt to their own circumstances without feeling a need to conform. Reliability and constructiveness – they can be trusted to act constructively. An individual who is open to all their needs will be able to maintain a balance between them. Even aggressive needs will be matched and balanced by intrinsic goodness in congruent individuals. A rich full life – he describes the life of the fully functioning individual as rich, full and exciting and suggests that they experience joy and pain, love and heartbreak, fear and courage more intensely. Rogers' description of the good life: Incongruence Rogers identified the "real self" as the aspect of a person that is founded in the actualizing tendency, follows organismic values and needs, and receives positive regard from others and self. On the other hand, to the extent that society is out of sync with the actualizing tendency, and people are forced to live with conditions of worth that are out of step with organismic valuing, and receive only conditional positive regard and self-regard, Rogers said that people develop instead an "ideal self". By ideal, Rogers was suggesting something not real, something that is always out of reach, a standard people cannot meet. This gap between the real self and the ideal self, the "I am" and the "I should", Rogers called incongruity. Psychopathology Rogers described the concepts of congruence and incongruence as important ideas in his theory. In proposition #6, he refers to the actualizing tendency. At the same time, he recognized the need for positive regard. In a fully congruent person, realizing their potential is not at the expense of experiencing positive regard. They are able to lead lives that are authentic and genuine. Incongruent individuals, in their pursuit of positive regard, lead lives that include falseness and do not realize their potential. Conditions put on them by those around them make it necessary for them to forgo their genuine, authentic lives to meet with the approval of others. They live lives that are not true to themselves, to who they are on the inside out. Rogers suggested that the incongruent individual, who is always on the defensive and cannot be open to all experiences, is not functioning ideally and may even be malfunctioning. They work hard at maintaining and protecting their self-concept. Because their lives are not authentic this is a difficult task and they are under constant threat. They deploy defense mechanisms to achieve this. He describes two mechanisms: distortion and denial. Distortion occurs when the individual perceives a threat to their self-concept. They distort the perception until it fits their self-concept. This defensive behavior reduces the consciousness of the threat but not the threat itself. And so, as the threats mount, the work of protecting the self-concept becomes more difficult and the individual becomes more defensive and rigid in their self-structure. If the incongruence is immoderate this process may lead the individual to a state that would typically be described as neurotic. Their functioning becomes precarious and psychologically vulnerable. If the situation worsens it is possible that the defenses cease to function altogether and the individual becomes aware of the incongruence of their situation. Their personality becomes disorganised and bizarre; irrational behavior, associated with earlier denied aspects of self, may erupt uncontrollably. Applications Person-centered therapy Rogers originally developed his theory to be the foundation for a system of therapy. He initially called this "non-directive therapy" but later replaced the term "non-directive" with the term "client-centered" and then later used the term "person-centered". Even before the publication of Client-Centered Therapy in 1951, Rogers believed that the principles he was describing could be applied in a variety of contexts and not just in the therapy situation. As a result, he started to use the term person-centered approach later in his life to describe his overall theory. Person-centered therapy is the application of the person-centered approach to the therapy situation. Other applications include a theory of personality, interpersonal relations, education, nursing, cross-cultural relations and other "helping" professions and situations. In 1946 Rogers co-authored "Counseling with Returned Servicemen" with John L. Wallen (the creator of the behavioral model known as The Interpersonal Gap), documenting the application of person-centered approach to counseling military personnel returning from the second world war. The first empirical evidence of the effectiveness of the client-centered approach was published in 1941 at the Ohio State University by Elias Porter, using the recordings of therapeutic sessions between Carl Rogers and his clients. Porter used Rogers' transcripts to devise a system to measure the degree of directiveness or non-directiveness a counselor employed.

They work hard at maintaining and protecting their self-concept. Because their lives are not authentic this is a difficult task and they are under constant threat. They deploy defense mechanisms to achieve this. He describes two mechanisms: distortion and denial. Distortion occurs when the individual perceives a threat to their self-concept. They distort the perception until it fits their self-concept. This defensive behavior reduces the consciousness of the threat but not the threat itself. And so, as the threats mount, the work of protecting the self-concept becomes more difficult and the individual becomes more defensive and rigid in their self-structure. If the incongruence is immoderate this process may lead the individual to a state that would typically be described as neurotic. Their functioning becomes precarious and psychologically vulnerable. If the situation worsens it is possible that the defenses cease to function altogether and the individual becomes aware of the incongruence of their situation. Their personality becomes disorganised and bizarre; irrational behavior, associated with earlier denied aspects of self, may erupt uncontrollably. Applications Person-centered therapy Rogers originally developed his theory to be the foundation for a system of therapy. He initially called this "non-directive therapy" but later replaced the term "non-directive" with the term "client-centered" and then later used the term "person-centered". Even before the publication of Client-Centered Therapy in 1951, Rogers believed that the principles he was describing could be applied in a variety of contexts and not just in the therapy situation. As a result, he started to use the term person-centered approach later in his life to describe his overall theory. Person-centered therapy is the application of the person-centered approach to the therapy situation. Other applications include a theory of personality, interpersonal relations, education, nursing, cross-cultural relations and other "helping" professions and situations. In 1946 Rogers co-authored "Counseling with Returned Servicemen" with John L. Wallen (the creator of the behavioral model known as The Interpersonal Gap), documenting the application of person-centered approach to counseling military personnel returning from the second world war. The first empirical evidence of the effectiveness of the client-centered approach was published in 1941 at the Ohio State University by Elias Porter, using the recordings of therapeutic sessions between Carl Rogers and his clients. Porter used Rogers' transcripts to devise a system to measure the degree of directiveness or non-directiveness a counselor employed. The attitude and orientation of the counselor were demonstrated to be instrumental in the decisions made by the client. Learner-centered teaching The application to education has a large robust research tradition similar to that of therapy with studies having begun in the late 1930s and continuing today (Cornelius-White, 2007). Rogers described the approach to education in Client-Centered Therapy and wrote Freedom to Learn devoted exclusively to the subject in 1969. Freedom to Learn was revised two times. The new Learner-Centered Model is similar in many regards to this classical person-centered approach to education. Rogers and Harold Lyon began a book prior to Rogers death, entitled On Becoming an Effective Teacher—Person-centered Teaching, Psychology, Philosophy, and Dialogues with Carl R. Rogers and Harold Lyon, which was completed by Lyon and Reinhard Tausch and published in 2013 containing Rogers last unpublished writings on person-centered teaching. Rogers had the following five hypotheses regarding learner-centered education: "A person cannot teach another person directly; a person can only facilitate another's learning" (Rogers, 1951). This is a result of his personality theory, which states that everyone exists in a constantly changing world of experience in which he or she is the center. Each person reacts and responds based on perception and experience. The belief is that what the student does is more important than what the teacher does. The focus is on the student (Rogers, 1951). Therefore, the background and experiences of the learner are essential to how and what is learned. Each student will process what he or she learns differently depending on what he or she brings to the classroom. "A person learns significantly only those things that are perceived as being involved in the maintenance of or enhancement of the structure of self" (Rogers, 1951). Therefore, relevancy to the student is essential for learning. The students' experiences become the core of the course. "Experience which, if assimilated, would involve a change in the organization of self, tends to be resisted through denial or distortion of symbolism" (Rogers, 1951). If the content or presentation of a course is inconsistent with preconceived information, the student will learn if he or she is open to varying concepts. Being open to consider concepts that vary from one's own is vital to learning. Therefore, gently encouraging open-mindedness is helpful in engaging the student in learning. Also, it is important, for this reason, that new information be relevant and related to existing experience. "The structure and organization of self appears to become more rigid under threats and to relax its boundaries when completely free from threat" (Rogers, 1951). If students believe that concepts are being forced upon them, they might become uncomfortable and fearful. A barrier is created by a tone of threat in the classroom. Therefore, an open, friendly environment in which trust is developed is essential in the classroom. Fear of retribution for not agreeing with a concept should be eliminated. A classroom tone of support helps to alleviate fears and encourages students to have the courage to explore concepts and beliefs that vary from those they bring to the classroom. Also, new information might threaten the student's concept of him- or herself; therefore, the less vulnerable the student feels, the more likely he or she will be able to open up to the learning process. "The educational situation which most effectively promotes significant learning is one in which (a) threat to the self of the learner is reduced to a minimum and (b) differentiated perception of the field is facilitated" (Rogers, 1951). The instructor should be open to learning from the students and also working to connect the students to the subject matter. Frequent interaction with the students will help achieve this goal. The instructor's acceptance of being a mentor who guides rather than the expert who tells is instrumental to student-centered, nonthreatening, and unforced learning. Rogerian rhetorical approach In 1970, Richard Young, Alton L. Becker, and Kenneth Pike published Rhetoric: Discovery and Change, a widely influential college writing textbook that used a Rogerian approach to communication to revise the traditional Aristotelian framework for rhetoric. The Rogerian method of argument involves each side restating the other's position to the satisfaction of the other, among other principles. In a paper, it can be expressed by carefully acknowledging and understanding the opposition, rather than dismissing them. Cross-cultural relations The application to cross-cultural relations has involved workshops in highly stressful situations and global locations including conflicts and challenges in South Africa, Central America, and Ireland. Along with Alberto Zucconi and Charles Devonshire, he co-founded the Istituto dell'Approccio Centrato sulla Persona (Person-Centered Approach Institute) in Rome, Italy. His international work for peace culminated in the Rust Peace Workshop which took place in November 1985 in Rust, Austria. Leaders from 17 nations convened to discuss the topic "The Central America Challenge". The meeting was notable for several reasons: it brought national figures together as people (not as their positions), it was a private event, and was an
width a are highly constrained so that the energy E of any one mode is widely separated from that of the next. This is not the case in the large region L, where there is a large number (numbering about L/a) of states with energy evenly spaced between E and the next mode in the narrow slot – in other words, all slightly larger than E. Now on shortening a by da (< 0), the mode in the narrow slot shrinks in wavelength and therefore increases in energy proportional to −da/a, whereas all the L/a states that lie in the large region lengthen and correspondingly decrease their energy by an amount proportional to da/L (note the denominator). The two effects nearly cancel, but the net change is slightly negative, because the energy of all the L/a modes in the large region are slightly larger than the single mode in the slot. Thus the force is attractive: it tends to make a slightly smaller, the plates attracting each other across the thin slot. Derivation of Casimir effect assuming zeta-regularization See Wikiversity for an elementary calculation in one dimension. In the original calculation done by Casimir, he considered the space between a pair of conducting metal plates at distance apart. In this case, the standing waves are particularly easy to calculate, because the transverse component of the electric field and the normal component of the magnetic field must vanish on the surface of a conductor. Assuming the plates lie parallel to the xy-plane, the standing waves are where stands for the electric component of the electromagnetic field, and, for brevity, the polarization and the magnetic components are ignored here. Here, and are the wave numbers in directions parallel to the plates, and is the wave-number perpendicular to the plates. Here, n is an integer, resulting from the requirement that ψ vanish on the metal plates. The frequency of this wave is where c is the speed of light. The vacuum energy is then the sum over all possible excitation modes. Since the area of the plates is large, we may sum by integrating over two of the dimensions in k-space. The assumption of periodic boundary conditions yields, where A is the area of the metal plates, and a factor of 2 is introduced for the two possible polarizations of the wave. This expression is clearly infinite, and to proceed with the calculation, it is convenient to introduce a regulator (discussed in greater detail below). The regulator will serve to make the expression finite, and in the end will be removed. The zeta-regulated version of the energy per unit-area of the plate is In the end, the limit is to be taken. Here s is just a complex number, not to be confused with the shape discussed previously. This integral/sum is finite for s real and larger than 3. The sum has a pole at s=3, but may be analytically continued to s=0, where the expression is finite. The above expression simplifies to: where polar coordinates were introduced to turn the double integral into a single integral. The in front is the Jacobian, and the comes from the angular integration. The integral converges if Re[s] > 3, resulting in The sum diverges at s in the neighborhood of zero, but if the damping of large-frequency excitations corresponding to analytic continuation of the Riemann zeta function to s=0 is assumed to make sense physically in some way, then one has But and so one obtains The analytic continuation has evidently lost an additive positive infinity, somehow exactly accounting for the zero-point energy (not included above) outside the slot between the plates, but which changes upon plate movement within a closed system. The Casimir force per unit area for idealized, perfectly conducting plates with vacuum between them is where (hbar, ħ) is the reduced Planck constant, is the speed of light, is the distance between the two plates The force is negative, indicating that the force is attractive: by moving the two plates closer together, the energy is lowered. The presence of shows that the Casimir force per unit area is very small, and that furthermore, the force is inherently of quantum-mechanical origin. By integrating the equation above it is possible to calculate the energy required to separate to infinity the two plates as: where (hbar, ħ) is the reduced Planck constant, is the speed of light, is the area of one of the plates, is the distance between the two plates In Casimir's original derivation, a moveable conductive plate is positioned at a short distance a from one of two widely separated plates (distance L apart). The 0-point energy on both sides of the plate is considered. Instead of the above ad hoc analytic continuation assumption, non-convergent sums and integrals are computed using Euler–Maclaurin summation with a regularizing function (e.g., exponential regularization) not so anomalous as in the above. More recent theory Casimir's analysis of idealized metal plates was generalized to arbitrary dielectric and realistic metal plates by Evgeny Lifshitz and his students. Using this approach, complications of the bounding surfaces, such as the modifications to the Casimir force due to finite conductivity, can be calculated numerically using the tabulated complex dielectric functions of the bounding materials. Lifshitz's theory for two metal plates reduces to Casimir's idealized 1/a4 force law for large separations a much greater than the skin depth of the metal, and conversely reduces to the 1/a3 force law of the London dispersion force (with a coefficient called a Hamaker constant) for small a, with a more complicated dependence on a for intermediate separations determined by the dispersion of the materials. Lifshitz's result was subsequently generalized to arbitrary multilayer planar geometries as well as to anisotropic and magnetic materials, but for several decades the calculation of Casimir forces for non-planar geometries remained limited to a few idealized cases admitting analytical solutions. For example, the force in the experimental sphere–plate geometry was computed with an approximation (due to Derjaguin) that the sphere radius R is much larger than the separation a, in which case the nearby surfaces are nearly parallel and the parallel-plate result can be adapted to obtain an approximate R/a3 force (neglecting both skin-depth and higher-order curvature effects). However, in the 2000s a number of authors developed and demonstrated a variety of numerical techniques, in many cases adapted from classical computational electromagnetics, that are capable of accurately calculating Casimir forces for arbitrary geometries and materials, from simple finite-size effects of finite plates to more complicated phenomena arising for patterned surfaces or objects of various shapes. Measurement One of the first experimental tests was conducted by Marcus Sparnaay at Philips in Eindhoven (Netherlands), in 1958, in a delicate and difficult experiment with parallel plates, obtaining results not in contradiction with the Casimir theory, but with large experimental errors. The Casimir effect was measured more accurately in 1997 by Steve K. Lamoreaux of Los Alamos National Laboratory, and by Umar Mohideen and Anushree Roy of the University of California, Riverside. In practice, rather than using two parallel plates, which would require phenomenally accurate alignment to ensure they were parallel, the experiments use one plate that is flat and another plate that is a part of a sphere with a very large radius. In 2001, a group (Giacomo Bressi, Gianni Carugno, Roberto Onofrio and Giuseppe Ruoso) at the University of Padua (Italy) finally succeeded in measuring the Casimir force between parallel plates using microresonators. In 2013, a conglomerate of scientists from Hong Kong University of Science and Technology, University of Florida, Harvard University, Massachusetts Institute of Technology, and Oak Ridge National Laboratory demonstrated a compact integrated silicon chip that can measure the Casimir force. The integrated chip defined by electron-beam lithography does not need extra alignment, making it an ideal platform for measuring Casimir force between complex geometries. In 2017 and 2021, the same group from Hong Kong University of Science and Technology demonstrated the non-monotonic Casimir force and distance-independent Casimir force, respectively, using this on-chip platform. Regularization In order to be able to perform calculations in the general case, it is convenient to introduce a regulator in the summations. This is an artificial device, used to make the sums finite so that they can be more easily manipulated, followed by the taking of a limit so as to remove the regulator. The heat kernel or exponentially regulated sum is where the limit is taken in the end. The divergence of the sum is typically manifested as for three-dimensional cavities. The infinite part of the sum is associated with the bulk constant C which does not depend on the shape of the cavity. The interesting part of the sum is the finite part, which is shape-dependent. The Gaussian regulator is better suited to numerical calculations because of its superior convergence properties, but is more difficult to use in theoretical calculations. Other, suitably smooth, regulators may be used as well. The zeta function regulator is completely unsuited for numerical calculations, but is quite useful in theoretical calculations. In particular, divergences show up as poles in the complex s plane, with the bulk divergence at s=4. This sum may be analytically continued past this pole, to obtain a finite part at s=0. Not every cavity configuration necessarily leads to a finite part (the lack of a pole at s=0) or shape-independent infinite parts. In this case, it should be understood that additional physics has to be taken into account. In particular, at extremely large frequencies (above the plasma frequency), metals become transparent to photons (such as X-rays), and dielectrics show a frequency-dependent cutoff as well. This frequency dependence acts as a natural regulator. There are a variety of bulk effects in solid state physics, mathematically very similar to the Casimir effect, where the cutoff frequency comes into explicit play to keep expressions finite. (These are discussed in greater detail in Landau and Lifshitz, "Theory of Continuous Media".) Generalities The Casimir effect can also be computed using the mathematical mechanisms of functional integrals of quantum field theory, although such calculations are considerably more abstract, and thus difficult to comprehend. In addition, they can be carried out only for the simplest of geometries. However, the formalism of quantum field theory makes it clear that the vacuum expectation value summations are in a certain sense summations over so-called "virtual particles". More interesting is the understanding that the sums over the energies of standing waves should be formally understood as sums over the eigenvalues of a Hamiltonian. This allows atomic and molecular effects, such as the van der Waals force, to be understood as a variation on the theme of the Casimir effect. Thus one considers the Hamiltonian of a system as a function of the arrangement of objects, such as atoms, in configuration space. The change in the zero-point energy as a function of changes of the configuration can be understood to result in forces acting between the objects. In the chiral bag model of the nucleon, the Casimir energy plays an important role in showing the mass of the nucleon is independent of the bag radius. In addition, the spectral asymmetry is interpreted as a non-zero vacuum expectation value of the baryon number, cancelling the topological winding number of the pion field surrounding the nucleon. A "pseudo-Casimir" effect can be found in liquid crystal systems, where the boundary conditions imposed through anchoring by rigid walls give rise to a long-range force, analogous to the force that arises between conducting plates. Dynamical Casimir effect The dynamical Casimir effect is the production of particles and energy from an accelerated moving mirror. This reaction was predicted by certain numerical solutions to quantum mechanics equations made in the 1970s. In May 2011 an announcement was made by researchers at the Chalmers University of Technology, in Gothenburg, Sweden, of the detection of the dynamical Casimir effect. In their experiment, microwave photons were generated out of the vacuum in a superconducting microwave resonator. These researchers used a modified SQUID to change the effective length of the resonator in time, mimicking a mirror moving at the required relativistic velocity. If confirmed this would be the first experimental verification of the dynamical Casimir effect. In March 2013 an article appeared on the PNAS scientific journal describing an experiment that demonstrated the dynamical Casimir effect in a Josephson metamaterial. In July 2019 an article was published describing an experiment providing evidence

the leading trade powers of the time. It seems Cyrus initially adopted the Lydian coinage as such, and continued to strike Lydia's lion-and-bull coinage. Original coins of the Achaemenid Empire were issued from 520 BCE – 450 BCE to 330 BCE. The Persian Daric was the first truly Achaemenid gold coin which, along with a similar silver coin, the Siglos, represented the bimetallic monetary standard of the Achaemenid Persian Empire. Coinage of Southern Asia under the Achaemenid Empire The Achaemenid Empire already reached the doors of India during the original expansion of Cyrus the Great, and the Achaemenid conquest of the Indus Valley is dated to c. 515 BCE under Darius I. An Achaemenid administration was established in the area. The Kabul hoard, also called the Chaman Hazouri hoard, is a coin hoard discovered in the vicinity of Kabul, Afghanistan, containing numerous Achaemenid coins as well as many Greek coins from the 5th and 4th centuries BCE. The deposit of the hoard is dated to the Achaemenid period, in approximately 380 BCE. The hoard also contained many locally produced silver coins, minted by local authorities under Achaemenid rule. Several of these issues follow the "western designs" of the facing bull heads, a stag, or Persian column capitals on the obverse, and incuse punch on the reverse. According to numismatist Joe Cribb, these finds suggest that the idea of coinage and the use of punch-marked techniques was introduced to India from the Achaemenid Empire during the 4th century BCE. More Achaemenid coins were also found in Pushkalavati and in Bhir Mound. Greek Archaic coinage (until about 480 BCE) According to Aristotle (fr. 611,37, ed. V. Rose) and Pollux (Onamastikon IX.83), the first issuer of Greek coinage was Hermodike of Kyme. A small percentage of early Lydian/Greek coins have a legend. The most ancient inscribed coin known is from nearby Caria. This coin has a Greek legend reading phaenos emi sema interpreted variously as "I am the badge of Phanes", or "I am the sign of light". The Phanes coins are among the earliest of Greek coins; a hemihekte of the issue was found in the foundation deposit of the temple of Artemis at Ephesos (the oldest deposit of electrum coins discovered). One assumption is that Phanes was a mercenary mentioned by Herodotus, another that this coin is associated with the primeval god Phanes or "Phanes" might have been an epithet of the local goddess identified with Artemis. Barclay V. Head found these suggestions unlikely and thought it more probably "the name of some prominent citizen of Ephesus". Another candidate for the site of the earliest coins is Aegina, where Chelone ("turtle") coins were first minted circa 700 BCE. Coins from Athens and Corinth appeared shortly thereafter, known to exist at least since the late 6th century BCE. Antiquity Classical Greek antiquity (480 BCE~) The Classical period saw Greek coinage reach a high level of technical and aesthetic quality. Larger cities now produced a range of fine silver and gold coins, most bearing a portrait of their patron god or goddess or a legendary hero on one side, and a symbol of the city on the other. Some coins employed a visual pun: some coins from Rhodes featured a rose, since the Greek word for rose is rhodon. The use of inscriptions on coins also began, usually the name of the issuing city. The wealthy cities of Sicily produced some especially fine coins. The large silver decadrachm (10-drachm) coin from Syracuse is regarded by many collectors as the finest coin produced in the ancient world, perhaps ever. Syracusan issues were rather standard in their imprints, one side bearing the head of the nymph Arethusa and the other usually a victorious quadriga. The tyrants of Syracuse were fabulously rich, and part of their public relations policy was to fund quadrigas for the Olympic chariot race, a very expensive undertaking. As they were often able to finance more than one quadriga at a time, they were frequent victors in this highly prestigious event. Syracuse was one of the epicenters of numismatic art during the classical period. Led by the engravers Kimon and Euainetos, Syracuse produced some of the finest coin designs of antiquity. Amongst the first centers to produce coins during the Greek colonization of mainland Southern Italy (Magna Graecia) were Paestum, Crotone, Sybaris, Caulonia, Metapontum, and Taranto. These ancient cities started producing coins from 550BCE to 510BCE. Amisano, in a general publication, including the Etruscan coinage, attributing it the beginning to about 560 BCE in Populonia, a chronology that would leave out the contribution of the Greeks of Magna Graecia and attribute to the Etruscans the burden of introducing the coin in Italy. In this work, constant reference is made to classical sources, and credit is given to the origin of the Etruscan Lydia, a source supported by Herodotus, and also to the invention of coin in Lydia. Appearance of dynastic portraiture (5th century BCE) Although many of the first coins illustrated the images of various gods, the first portraiture of actual rulers appears with the coinage of Lycia in the 5th century BCE. No ruler had dared illustrating his own portrait on coinage until that time. The Achaemenids had been the first to illustrate the person of their king or a hero in a stereotypical manner, showing a bust or the full body but never an actual portrait, on their Sigloi and Daric coinage from circa 500 BCE. A slightly earlier candidate for the first portrait-coin is Themistocles the Athenian general, who became a Governor of Magnesia on the Meander circa 465–459 BCE for the Achaemenid Empire, although there is some doubt that his coins may have represented Zeus rather than himself. Themistocles may have been in a unique position in which he could transfer the notion of individual portraiture, already current in the Greek world, and at the same time wield the dynastic power of an Achaemenid dynasty who could issue his own coins and illustrate them as he wished. From the time of Alexander the Great, portraiture of the issuing ruler would then become a standard, generalized, feature of coinage. Indian coins (circa 400 BCE–100 CE) The Karshapana is the earliest punch-marked coin found in India, produced from at least the mid-4th century BCE, and possibly as early as 575 BCE, influenced by similar coins produced in Gandhara under the Achaemenid empire, such as those of the Kabul hoard, or other examples found at Pushkalavati and in Bhir Mound. Chinese round coins (350 BCE~) In China, early round coins appeared in the 4th century BCE and were adopted for all China by Emperor Qin Shi Huang Di at the end of 3rd century BCE. The round coin, the precursor of the familiar cash coin, circulated in both the spade and knife money areas in the Zhou period, from around 350 BCE. Apart from two small and presumably late coins from the State of Qin, coins from the spade money area have a round hole and refer to the jin and liang units. Those from the knife money area have a square hole and are denominated in hua (化). Although for discussion purposes the Zhou coins are divided up into categories of knives, spades, and round coins, it is apparent from archaeological finds that most of the various kinds circulated together. A hoard found in 1981, near Hebi in north Henan province, consisted of: 3,537 Gong spades, 3 Anyi arched foot spades, 8 Liang Dang Lie spades, 18 Liang square foot spades and 1,180 Yuan round coins, all contained in three clay jars. Hellenistic period (320 BCE – 30 CE) The Hellenistic period was characterized by the spread of Greek culture across a large part of the known world. Greek-speaking kingdoms were established in Egypt and Syria, and for a time also in Iran and as far east as what is now Afghanistan and northwestern India. Greek traders spread Greek coins across this vast area, and the new kingdoms soon began to produce their own coins. Because these kingdoms were much larger and wealthier than the Greek city states of the classical period, their coins tended to be more mass-produced, as well as larger, and more frequently in gold. They often lacked the aesthetic delicacy of coins of the earlier period. Still, some of the Greco-Bactrian coins, and those of their successors in India, the Indo-Greeks, are considered the finest examples of Greek numismatic art with "a nice blend of realism and idealization", including the largest coins to be minted in the Hellenistic world: the largest gold coin was minted by Eucratides (reigned 171–145 BCE), the largest silver coin by the Indo-Greek king Amyntas Nikator (reigned c. 95–90 BCE). The portraits "show a degree of individuality never matched by the often bland depictions of their royal contemporaries further West" (Roger Ling, "Greece and the Hellenistic World"). Roman period (290 BCE~) Coinage followed Greek colonization and influence first around the Mediterranean and soon after to North Africa (including Egypt), Syria, Persia, and the Balkans. Coins came late to the Roman Republic compared with the rest of the Mediterranean, especially Greece and Asia Minor where coins were invented in the 7th century BCE. The currency of central Italy was influenced by its natural resources, with bronze being abundant (the Etruscans were famous metal workers in bronze and iron) and silver ore being scarce. The coinage of the Roman Republic started with a few silver coins apparently devised for trade with Celtic in northern Italy and the Greek colonies in Southern Italy, and heavy cast bronze pieces for use in Central Italy. The first Roman coins, which
bearing the name ΦΑΝΕΟΣ (“of Phanes”). The first electrum coins issued by a monarch are those minted by king Alyattes of Lydia (died c. 560 BCE), for which reason this king is sometimes mentioned as the originator of coinage. Croesus: Pure gold and silver coins The successor of Alyattes, king Croesus (r. c. 560–546 BCE), became associated with great wealth in Greek historiography. He is credited with issuing the Croeseid, the first true gold coins with a standardized purity for general circulation. and the world's first bimetallic monetary system c. 550 BCE. Coins spread rapidly in the 6th and 5th centuries BCE, leading to the development of Ancient Greek coinage and Achaemenid coinage, and further to Illyrian coinage. Standardized Roman currency was used throughout the Roman Empire. Important Roman gold and silver coins were continued into the Middle Ages (see Gold dinar, Solidus, Aureus, Denarius). Ancient and early medieval coins in theory had the value of their metal content, although there have been many instances throughout history of governments inflating their currencies by debasing the metal content of their coinage, so that the inferior coins were worth less in metal than their face value. Fiat money first arose in medieval China, with the jiaozi paper money. Early paper money was introduced in Europe in the later Middle Ages, but some coins continued to have the value of the gold or silver they contained throughout the Early Modern period. The penny was minted as a silver coin until the 17th century. Achaemenid coinage (546–330 BCE) When Cyrus the Great (550–530 BC) came to power, coinage was unfamiliar in his realm. Barter and to some extent silver bullion was used instead for trade. The practice of using silver bars for currency also seems to have been current in Central Asia from the 6th century. Cyrus the Great introduced coins to the Persian Empire after 546 BCE, following his conquest of Lydia and the defeat of its king Croesus, who had put in place the first coinage in history. With his conquest of Lydia, Cyrus acquired a region in which coinage was invented, developed through advanced metallurgy, and had already been in circulation for about 50 years, making the Lydian Kingdom one of the leading trade powers of the time. It seems Cyrus initially adopted the Lydian coinage as such, and continued to strike Lydia's lion-and-bull coinage. Original coins of the Achaemenid Empire were issued from 520 BCE – 450 BCE to 330 BCE. The Persian Daric was the first truly Achaemenid gold coin which, along with a similar silver coin, the Siglos, represented the bimetallic monetary standard of the Achaemenid Persian Empire. Coinage of Southern Asia under the Achaemenid Empire The Achaemenid Empire already reached the doors of India during the original expansion of Cyrus the Great, and the Achaemenid conquest of the Indus Valley is dated to c. 515 BCE under Darius I. An Achaemenid administration was established in the area. The Kabul hoard, also called the Chaman Hazouri hoard, is a coin hoard discovered in the vicinity of Kabul, Afghanistan, containing numerous Achaemenid coins as well as many Greek coins from the 5th and 4th centuries BCE. The deposit of the hoard is dated to the Achaemenid period, in approximately 380 BCE. The hoard also contained many locally produced silver coins, minted by local authorities under Achaemenid rule. Several of these issues follow the "western designs" of the facing bull heads, a stag, or Persian column capitals on the obverse, and incuse punch on the reverse. According to numismatist Joe Cribb, these finds suggest that the idea of coinage and the use of punch-marked techniques was introduced to India from the Achaemenid Empire during the 4th century BCE. More Achaemenid coins were also found in Pushkalavati and in Bhir Mound. Greek Archaic coinage (until about 480 BCE) According to Aristotle (fr. 611,37, ed. V. Rose) and Pollux (Onamastikon IX.83), the first issuer of Greek coinage was Hermodike of Kyme. A small percentage of early Lydian/Greek coins have a legend. The most ancient inscribed coin known is from nearby Caria. This coin has a Greek legend reading phaenos emi sema interpreted variously as "I am the badge of Phanes", or "I am the sign of light". The Phanes coins are among the earliest of Greek coins; a hemihekte of the issue was found in the foundation deposit of the temple of Artemis at Ephesos (the oldest deposit of electrum coins discovered). One assumption is that Phanes was a mercenary mentioned by Herodotus, another that this coin is associated with the primeval god Phanes or "Phanes" might have been an epithet of the local goddess identified with Artemis. Barclay V. Head found these suggestions unlikely and thought it more probably "the name of some prominent citizen of Ephesus". Another candidate for the site of the earliest coins is Aegina, where Chelone ("turtle") coins were first minted circa 700 BCE. Coins from Athens and Corinth appeared shortly thereafter, known to exist at least since the late 6th century BCE. Antiquity Classical Greek antiquity (480 BCE~) The Classical period saw Greek coinage reach a high level of technical and aesthetic quality. Larger cities now produced a range of fine silver and gold coins, most bearing a portrait of their patron god or goddess or a legendary hero on one side, and a symbol of the city on the other. Some coins employed a visual pun: some coins from Rhodes featured a rose, since the Greek word for rose is rhodon. The use of inscriptions on coins also began, usually the name of the issuing city. The wealthy cities of Sicily produced some especially fine coins. The large silver decadrachm (10-drachm) coin from Syracuse is regarded by many collectors as the finest coin produced in the ancient world, perhaps ever. Syracusan issues were rather standard in their imprints, one side bearing the head of the nymph Arethusa and the other usually a victorious quadriga. The tyrants of Syracuse were fabulously rich, and part of their public relations policy was to fund quadrigas for the Olympic chariot race, a very expensive undertaking. As they were often able to finance more than one quadriga at a time, they were frequent victors in this highly prestigious event. Syracuse was one of the epicenters of numismatic art during the classical period. Led by the engravers Kimon and Euainetos, Syracuse produced some of the finest coin designs of antiquity. Amongst the first centers to produce coins during the Greek colonization of mainland Southern Italy (Magna Graecia) were Paestum, Crotone, Sybaris, Caulonia, Metapontum, and Taranto. These ancient cities started producing coins from 550BCE to 510BCE. Amisano, in a general publication, including the Etruscan coinage, attributing it the beginning to about 560 BCE in Populonia, a chronology that would leave out the contribution of the Greeks of Magna Graecia and attribute to the Etruscans the burden of introducing the coin in Italy. In this work, constant reference is made to classical sources, and credit is given to the origin of the Etruscan Lydia, a source supported by Herodotus, and also to the invention of coin in Lydia. Appearance of dynastic portraiture (5th century BCE) Although many of the first coins illustrated the images of various gods, the first portraiture of actual rulers appears with the coinage of Lycia in the 5th century BCE. No ruler had dared illustrating his own portrait on coinage until that time. The Achaemenids had been the first to illustrate the person of their king or a hero in a stereotypical manner, showing a bust or the full body but never an actual portrait, on their Sigloi and Daric coinage from circa 500 BCE. A slightly earlier candidate for the first portrait-coin is Themistocles the Athenian general, who became a Governor of Magnesia on the Meander circa 465–459 BCE for the Achaemenid Empire, although there is some doubt that his coins may have represented Zeus rather than himself. Themistocles may have been in a unique position in which he could transfer the notion of individual portraiture, already current in the Greek world, and at the same time wield the dynastic power of an Achaemenid dynasty who could issue his own coins and illustrate them as he wished. From the time of Alexander the Great, portraiture of the issuing ruler would then become a standard, generalized, feature of coinage. Indian coins (circa 400 BCE–100 CE) The Karshapana is the earliest punch-marked coin found in India, produced from at least the mid-4th century BCE, and possibly as early as 575 BCE, influenced by similar coins produced in Gandhara under the Achaemenid empire, such as those of the Kabul hoard, or other examples found at Pushkalavati and in Bhir Mound. Chinese round coins (350 BCE~) In China, early round coins appeared in the 4th century BCE and were adopted for all China by Emperor Qin Shi Huang Di at the end of 3rd century BCE. The round coin, the precursor of the familiar cash coin, circulated in both the spade and knife money areas in the Zhou period, from around 350 BCE. Apart from two small and presumably late coins from the State of Qin, coins from the spade money area have a round hole and refer to the jin and liang units. Those from the knife money area have a square hole and are denominated in hua (化). Although for discussion purposes the Zhou coins are divided up into categories of knives, spades, and round coins, it is apparent from archaeological finds that most of the various kinds circulated together. A hoard found in 1981, near Hebi in north Henan province, consisted of: 3,537 Gong spades, 3 Anyi arched foot spades, 8 Liang Dang Lie spades, 18 Liang square foot spades and 1,180 Yuan round coins, all contained in three clay jars. Hellenistic period (320 BCE – 30 CE) The Hellenistic period was characterized by the spread of Greek culture across a large part of the known world. Greek-speaking kingdoms were established in Egypt and Syria, and for a time also in Iran and as far east as what is now Afghanistan and northwestern India. Greek traders spread Greek coins across this vast area, and the new kingdoms soon began to produce their own coins. Because these kingdoms were much larger and wealthier than the Greek city states of the classical period, their coins tended to be more mass-produced, as well as larger, and more frequently in gold. They often lacked the aesthetic delicacy of coins of the earlier period. Still, some of the Greco-Bactrian coins, and those of their successors in India, the Indo-Greeks, are considered the finest examples of Greek numismatic art with "a nice blend of realism and idealization", including the largest coins to be minted in the Hellenistic world: the largest gold coin was minted by Eucratides (reigned 171–145 BCE), the largest silver coin by the Indo-Greek king Amyntas Nikator (reigned c. 95–90 BCE). The portraits "show a degree of individuality never matched by the often bland depictions of their royal contemporaries further West" (Roger Ling, "Greece and the Hellenistic World"). Roman period (290 BCE~) Coinage followed Greek colonization and influence first around the Mediterranean and soon after to North Africa (including Egypt), Syria, Persia, and the Balkans.

The coinage of the Roman Republic started with a few silver coins apparently devised for trade with Celtic in northern Italy and the Greek colonies in Southern Italy, and heavy cast bronze pieces for use in Central Italy. The first Roman coins, which were crude, heavy cast bronzes, were issued c. 289 BCE. Amisano, in a general publication, including the Etruscan coinage, attributing it the beginning to about 550 BCE in Populonia, a chronology that would leave out the contribution of the Greeks of Magna Graecia and attribute to the Etruscans the burden of introducing the coin in Italy. In this work, constant reference is made to classical sources, and credit is given to the origin of the Etruscan Lydia, a source supported by Herodotus, and also to the invention of coin in Lydia. Middle Ages The first European coin to use Arabic numerals to date the year in which the coin was minted was the St. Gall silver Plappart of 1424. Modern history Value Currency Most coins presently are made of a base metal, and their value comes from their status as fiat money. This means that the value of the coin is decreed by government fiat (law), and thus is determined by the free market only in as much as national currencies are used in domestic trade and also traded internationally on foreign exchange markets. Thus, these coins are monetary tokens, just as paper currency is: they are usually not backed by metal, but rather by some form of government guarantee. Some have suggested that such coins not be considered to be "true coins" (see below). Thus, there is very little economic difference between notes and coins of equivalent face

basic dynamical classes of classical Kuiper-belt bodies: those with relatively unperturbed ('cold') orbits, and those with markedly perturbed ('hot') orbits. Most cubewanos are found between the 2:3 orbital resonance with Neptune (populated by plutinos) and the 1:2 resonance. 50000 Quaoar, for example, has a near-circular orbit close to the ecliptic. Plutinos, on the other hand, have more eccentric orbits bringing some of them closer to the Sun than Neptune. The majority of classical objects, the so-called cold population, have low inclinations (< 5°) and near-circular orbits, lying between 42 and 47 AU. A smaller population (the hot population) is characterised by highly inclined, more eccentric orbits. The terms 'hot' and 'cold' has nothing to do with surface or internal temperatures. Instead, the terms 'hot and 'cold' refer to the orbits of the objects, by analogy to particles in a gas, which increase their relative velocity as they become heated up. The Deep Ecliptic Survey reports the distributions of the two populations; one with the inclination centered at 4.6° (named Core) and another with inclinations extending beyond 30° (Halo). Distribution The vast majority of KBOs (more than two-thirds) have inclinations of less than 5° and eccentricities of less than 0.1 . Their semi-major axes show a preference for the middle of the main belt; arguably, smaller objects close to the limiting resonances have been either captured into resonance or have their orbits modified by Neptune. The 'hot' and 'cold' populations are strikingly different: more than 30% of all cubewanos are in low inclination, near-circular orbits. The parameters of the plutinos’ orbits are more evenly distributed, with a local maximum in moderate eccentricities in 0.15–0.2 range, and low inclinations 5–10°. See also the comparison with scattered disk objects. When the orbital eccentricities of cubewanos and plutinos are compared, it can be seen that the cubewanos form a clear 'belt' outside Neptune's orbit, whereas the plutinos approach, or even cross Neptune's orbit. When orbital inclinations are compared, 'hot' cubewanos can be easily distinguished by their higher inclinations, as the plutinos typically keep orbits below 20°. (No clear explanation currently exists for the inclinations of 'hot' cubewanos.) Cold and hot populations: physical characteristics In addition to the distinct orbital characteristics, the two populations display different physical characteristics. The difference in colour between the red cold population, such as 486958 Arrokoth, and more heterogeneous hot population was observed as early as in 2002. Recent studies, based on a larger data set, indicate the cut-off inclination of 12° (instead of 5°) between the cold and hot populations and confirm the distinction between the homogenous red cold population and the bluish hot population. Another difference between the low-inclination (cold) and high-inclination (hot) classical objects is the observed number of binary objects. Binaries are quite common on low-inclination orbits and are typically similar-brightness systems. Binaries are less common on high-inclination orbits and their components typically differ in brightness. This correlation, together with the differences in colour, support further the suggestion that the currently observed classical objects belong to at least two different overlapping populations, with different physical properties and orbital history. Toward a formal definition There is no official definition of 'cubewano' or 'classical KBO'. However, the terms are normally used to refer to objects free from significant perturbation from Neptune, thereby excluding KBOs in orbital resonance with Neptune (resonant trans-Neptunian objects). The Minor Planet Center (MPC) and the Deep Ecliptic Survey (DES) do not list cubewanos (classical objects) using the same criteria. Many TNOs classified as cubewanos by the MPC are classified as ScatNear (possibly scattered by Neptune) by the DES. Dwarf planet Makemake is such a borderline classical cubewano/scatnear object. may be an inner cubewano near the plutinos. Furthermore, there is evidence that the Kuiper belt has an 'edge', in that an apparent lack of low-inclination objects beyond

of a growing assertiveness by Congress about many aspects of Foreign Policy," Human Rights concerns became a battleground between the Legislative and the Executive branches in the formulation of foreign policy. David Forsythe points to three specific, early examples of Congress interjecting its own thoughts on foreign policy: Subsection (a) of the International Financial Assistance Act of 1977: ensured assistance through international financial institutions would be limited to countries "other than those whose governments engage in a consistent pattern of gross violations of internationally recognized human rights". Section 116 of the Foreign Assistance Act of 1961, as amended in 1984: reads in part, "No assistance may be provided under this part to the government of any country which engages in a consistent pattern of gross violations of internationally recognized human rights." Section 502B of the Foreign Assistance Act of 1961, as amended in 1978: "No security assistance may be provided to any country the government of which engages in a consistent pattern of gross violations of internationally recognized human rights." These measures were repeatedly used by Congress, with varying success, to affect U.S. foreign policy towards the inclusion of Human Rights concerns. Specific examples include El Salvador, Nicaragua, Guatemala and South Africa. The Executive (from Nixon to Reagan) argued that the Cold War required placing regional security in favor of U.S. interests over any behavioral concerns of national allies. Congress argued the opposite, in favor of distancing the United States from oppressive regimes. Nevertheless, according to historian Daniel Goldhagen, during the last two decades of the Cold War, the number of American client states practicing mass murder outnumbered those of the Soviet Union. John Henry Coatsworth, a historian of Latin America and the provost of Columbia University, suggests the number of repression victims in Latin America alone far surpassed that of the USSR and its East European satellites during the period 1960 to 1990. W. John Green contends that the United States was an "essential enabler" of "Latin America's political murder habit, bringing out and allowing to flourish some of the region's worst tendencies". On December 6, 2011, Obama instructed agencies to consider LGBT rights when issuing financial aid to foreign countries. He also criticized Russia's law discriminating against gays, joining other western leaders in the boycott of the 2014 Winter Olympics in Russia. In June 2014, a Chilean court ruled that the United States played a key role in the murders of Charles Horman and Frank Teruggi, both American citizens, shortly after the 1973 Chilean coup d'état. War on Drugs United States foreign policy is influenced by the efforts of the U.S. government to control imports of illicit drugs, including cocaine, heroin, methamphetamine, and cannabis. This is especially true in Latin America, a focus for the U.S. War on Drugs. Those efforts date back to at least 1880, when the U.S. and China completed an agreement that prohibited the shipment of opium between the two countries. Over a century later, the Foreign Relations Authorization Act requires the President to identify the major drug transit or major illicit drug-producing countries. In September 2005, the following countries were identified: Bahamas, Bolivia, Brazil, Burma, Colombia, Dominican Republic, Ecuador, Guatemala, Haiti, India, Jamaica, Laos, Mexico, Nigeria, Pakistan, Panama, Paraguay, Peru and Venezuela. Two of these, Burma and Venezuela are countries that the U.S. considers to have failed to adhere to their obligations under international counternarcotics agreements during the previous 12 months. Notably absent from the 2005 list were Afghanistan, the People's Republic of China and Vietnam; Canada was also omitted in spite of evidence that criminal groups there are increasingly involved in the production of MDMA destined for the United States and that large-scale cross-border trafficking of Canadian-grown cannabis continues. The U.S. believes that the Netherlands are successfully countering the production and flow of MDMA to the U.S. Criticism Critics from the left cite episodes that undercut leftist governments or showed support for Israel. Others cite human rights abuses and violations of international law. Critics have charged that the U.S. presidents have used democracy to justify military intervention abroad. Critics also point to declassified records which indicate that the CIA under Allen Dulles and the FBI under J. Edgar Hoover aggressively recruited more than 1,000 Nazis, including those responsible for war crimes, to use as spies and informants against the Soviet Union in the Cold War. The U.S. has faced criticism for backing right-wing dictators that systematically violated human rights, such as Augusto Pinochet of Chile, Alfredo Stroessner of Paraguay, Efraín Ríos Montt of Guatemala, Jorge Rafael Videla of Argentina, Hissène Habré of Chad Yahya Khan of Pakistan and Suharto of Indonesia. Critics have also accused the United States of facilitating and supporting state terrorism in the Global South during the Cold War, such as Operation Condor, an international campaign of political assassination and state terror organized by right-wing military dictatorships in the Southern Cone of South America. Journalists and human rights organizations have been critical of US-led airstrikes and targeted killings by drones which have in some cases resulted in collateral damage of civilian populations. In early 2017, the U.S. faced criticism from some scholars, activists and media outlets for dropping 26,171 bombs on seven countries throughout 2016: Syria, Iraq, Afghanistan, Libya, Yemen, Somalia and Pakistan. The U.S. has been accused of complicity in war crimes for backing the Saudi Arabian-led intervention into the Yemeni Civil War, which has triggered a humanitarian catastrophe, including a cholera outbreak and millions facing starvation. Studies have been devoted to the historical success rate of the U.S. in exporting democracy abroad. Some studies of American intervention have been pessimistic about the overall effectiveness of U.S. efforts to encourage democracy in foreign nations. Some scholars have generally agreed with international relations professor Abraham Lowenthal that U.S. attempts to export democracy have been "negligible, often counterproductive, and only occasionally positive". Other studies find U.S. intervention has had mixed results, and another by Hermann and Kegley has found that military interventions have improved democracy in other countries. A 2013 global poll in 68 countries with 66,000 respondents by Win/Gallup found that the U.S. is perceived as the biggest threat to world peace. America's history of non-intervention has been criticized as well. In his World Policy Journal review of Bill Kauffman's 1995 book America First! Its History, Culture, and Politics, Benjamin Schwartz described America's history of isolationism as a "tragedy" and being rooted in Puritan thinking. Support Regarding support for certain anti-Communist dictatorships during the Cold War, a response is that they were seen as a necessary evil, with the alternatives even worse Communist or fundamentalist dictatorships. David Schmitz says this policy did not serve U.S. interests. Friendly tyrants resisted necessary reforms and destroyed the political center (though not in South Korea), while the 'realist' policy of coddling dictators brought a backlash among foreign populations with long memories. Many democracies have voluntary military ties with the United States. See NATO, ANZUS, Treaty of Mutual Cooperation and Security between the United States and Japan, Mutual Defense Treaty with South Korea, and Major non-NATO ally. Those nations with military alliances with the U.S. can spend less on the military since they can count on U.S. protection. This may give a false impression that the U.S. is less peaceful than those nations. Research on the democratic peace theory has generally found that democracies, including the United States, have not made war on one another. There have been U.S. support for coups against some democracies, but for example Spencer R. Weart argues that part of the explanation was the perception, correct or not, that these states were turning into Communist dictatorships. Also important was the role of rarely transparent United States government agencies, who sometimes mislead or did not fully implement the decisions of elected civilian leaders. Empirical studies (see democide) have found that democracies, including the United States, have killed much fewer civilians than dictatorships. Media may be biased against the U.S. regarding reporting human rights violations. Studies have found that The New York Times coverage of worldwide human rights violations predominantly focuses on the human rights violations in nations where there is clear U.S. involvement, while having relatively little coverage of the human rights violations in other nations. For example, the bloodiest war in recent time, involving eight nations and killing millions of civilians, was the Second Congo War, which was almost completely ignored by the media. Niall Ferguson argues that the U.S. is incorrectly blamed for all the human rights violations in nations they have supported. He writes that it is generally agreed that Guatemala was the worst of the US-backed regimes during the Cold War. However, the U.S. cannot credibly be blamed for all the 200,000 deaths during the long Guatemalan Civil War. The U.S. Intelligence Oversight Board writes that military aid was cut for long periods because of such violations, that the U.S. helped stop a coup in 1993, and that efforts were made to improve the conduct of the security services. Today the U.S. states that democratic nations best support U.S. national interests. According to the U.S. State Department, "Democracy is the one national interest that helps to secure all the others. Democratically governed nations are more likely to secure the peace, deter aggression, expand open markets, promote economic development, protect American citizens, combat international terrorism and crime, uphold human and worker rights, avoid humanitarian crises and refugee flows, improve the global environment, and protect human health." According to former U.S. President Bill Clinton, "Ultimately, the best strategy to ensure our security and to build a durable peace is to support the advance of democracy elsewhere. Democracies don't attack each other." In one view mentioned by the U.S. State Department, democracy is also good for business. Countries that embrace political reforms are also more likely to pursue economic reforms that improve the productivity of businesses. Accordingly, since the mid-1980s, under President Ronald Reagan, there has been an increase in levels of foreign direct investment going to emerging market democracies relative to countries that have not undertaken political reforms. Leaked cables in 2010 suggested that the "dark shadow of terrorism still dominates the United States' relations with the world". The United States officially maintains that it supports democracy and human rights through several tools Examples of these tools are as follows: A published yearly report by the State Department entitled "Advancing Freedom and Democracy", issued in compliance with ADVANCE Democracy Act of 2007 (earlier the report was known as "Supporting Human Rights and Democracy: The U.S. Record" and was issued in compliance with a 2002 law). A yearly published "Country Reports on Human Rights Practices". In 2006 (under President George W. Bush), the United States created a "Human Rights Defenders Fund" and "Freedom Awards". The "Human Rights and Democracy Achievement Award" recognizes the exceptional achievement of officers of foreign affairs agencies posted abroad. The "Ambassadorial Roundtable Series", created in 2006, are informal discussions between newly confirmed U.S. Ambassadors and human rights and democracy non-governmental organizations. The National Endowment for Democracy, a private non-profit created by Congress in 1983 (and signed into law by President Ronald Reagan), which is mostly funded by the U.S. Government and gives cash grants to strengthen democratic institutions around the world.

addition to the deployment U.S. missile defenses, the DPG's second recommendation has also been proceeding on course. "Washington has pursued policies that have ignored Russian interests (and sometimes international law as well) in order to encircle Moscow with military alliances and trade blocs conducive to U.S. interests." Exporting democracy Studies have been devoted to the historical success rate of the U.S. in exporting democracy abroad. Some studies of American intervention have been pessimistic about the overall effectiveness of U.S. efforts to encourage democracy in foreign nations. Until recently, scholars have generally agreed with international relations professor Abraham Lowenthal that U.S. attempts to export democracy have been "negligible, often counterproductive, and only occasionally positive". Other studies find U.S. intervention has had mixed results, and another by Hermann and Kegley has found that military interventions have improved democracy in other countries. Global opinion International opinion about the US has often changed with different executive administrations. For example, in 2009, the French public favored the United States when President Barack Obama (75% favorable) replaced President George W. Bush (42%). After President Donald Trump took the helm in 2017, French public opinion about the US fell from 63% to 46%. These trends were also seen in other European countries. Covert actions United States foreign policy also includes covert actions to topple foreign governments that have been opposed to the United States. According to J. Dana Stuster, writing in Foreign Policy, there are seven "confirmed cases" where the U.S.—acting principally through the Central Intelligence Agency (CIA), but sometimes with the support of other parts of the U.S. government, including the Navy and State Department—covertly assisted in the overthrow of a foreign government: Iran in 1953, Guatemala in 1954, Congo in 1960, the Dominican Republic in 1961, South Vietnam in 1963, Brazil in 1964, and Chile in 1973. Stuster states that this list excludes "U.S.-supported insurgencies and failed assassination attempts" such as those directed against Cuba's Fidel Castro, as well as instances where U.S. involvement has been alleged but not proven (such as Syria in 1949). In 1953 the CIA, working with the British government, initiated Operation Ajax against the Prime Minister of Iran Mohammad Mossadegh who had attempted to nationalize Iran's oil, threatening the interests of the Anglo-Persian Oil Company. This had the effect of restoring and strengthening the authoritarian monarchical reign of Shah Mohammad Reza Pahlavi. In 1957, the CIA and Israeli Mossad aided the Iranian government in establishing its intelligence service, SAVAK, later blamed for the torture and execution of the regime's opponents. A year later, in Operation PBSuccess, the CIA assisted the local military in toppling the democratically elected left-wing government of Jacobo Árbenz in Guatemala and installing the military dictator Carlos Castillo Armas. The United Fruit Company lobbied for Árbenz overthrow as his land reforms jeopardized their land holdings in Guatemala, and painted these reforms as a communist threat. The coup triggered a decades long civil war which claimed the lives of an estimated 200,000 people (42,275 individual cases have been documented), mostly through 626 massacres against the Maya population perpetrated by the U.S.-backed Guatemalan military. An independent Historical Clarification Commission found that U.S. corporations and government officials "exercised pressure to maintain the country's archaic and unjust socio-economic structure," and that U.S. military assistance had a "significant bearing on human rights violations during the armed confrontation". During the massacre of at least 500,000 alleged communists in 1960s Indonesia, U.S. government officials encouraged and applauded the mass killings while providing covert assistance to the Indonesian military which helped facilitate them. This included the U.S. Embassy in Jakarta supplying Indonesian forces with lists of up to 5,000 names of suspected members of the Communist Party of Indonesia (PKI), who were subsequently killed in the massacres. In 2001, the CIA attempted to prevent the publication of the State Department volume Foreign Relations of the United States, 1964–1968, which documents the U.S. role in providing covert assistance to the Indonesian military for the express purpose of the extirpation of the PKI. In July 2016, an international panel of judges ruled the killings constitute crimes against humanity, and that the US, along with other Western governments, were complicit in these crimes. In 1970, the CIA worked with coup-plotters in Chile in the attempted kidnapping of General René Schneider, who was targeted for refusing to participate in a military coup upon the election of Salvador Allende. Schneider was shot in the botched attempt and died three days later. The CIA later paid the group $35,000 for the failed kidnapping. Influencing foreign elections According to one peer-reviewed study, the U.S. intervened in 81 foreign elections between 1946 and 2000, while the Soviet Union or Russia intervened in 36. Human rights Since the 1970s, issues of human rights have become increasingly important in American foreign policy. Congress took the lead in the 1970s. Following the Vietnam War, the feeling that U.S. foreign policy had grown apart from traditional American values was seized upon by Representative Donald M. Fraser (D, MN), leading the Subcommittee on International Organizations and Movements, in criticizing Republican Foreign Policy under the Nixon administration. In the early 1970s, Congress concluded the Vietnam War and passed the War Powers Act. As "part of a growing assertiveness by Congress about many aspects of Foreign Policy," Human Rights concerns became a battleground between the Legislative and the Executive branches in the formulation of foreign policy. David Forsythe points to three specific, early examples of Congress interjecting its own thoughts on foreign policy: Subsection (a) of the International Financial Assistance Act of 1977: ensured assistance through international financial institutions would be limited to countries "other than those whose governments engage in a consistent pattern of gross violations of internationally recognized human rights". Section 116 of the Foreign Assistance Act of 1961, as amended in 1984: reads in part, "No assistance may be provided under this part to the government of any country which engages in a consistent pattern of gross violations of internationally recognized human rights." Section 502B of the Foreign Assistance Act of 1961, as amended in 1978: "No security assistance may be provided to any country the government of which engages in a consistent pattern of gross violations of internationally recognized human rights." These measures were repeatedly used by Congress, with varying success, to affect U.S. foreign policy towards the inclusion of Human Rights concerns. Specific examples include El Salvador, Nicaragua, Guatemala and South Africa. The Executive (from Nixon to Reagan) argued that the Cold War required placing regional security in favor of U.S. interests over any behavioral concerns of national allies. Congress argued the opposite, in favor of distancing the United States from oppressive regimes. Nevertheless, according to historian Daniel Goldhagen, during the last two decades of the Cold War, the number of American client states practicing mass murder outnumbered those of the Soviet Union. John Henry Coatsworth, a historian of Latin America and the provost of Columbia University, suggests the number of repression victims in Latin America alone far surpassed that of the USSR and its East European satellites during the period 1960 to 1990. W. John Green contends that the United States was an "essential enabler" of "Latin America's political murder habit, bringing out and allowing to flourish some of the region's worst tendencies". On December 6, 2011, Obama instructed agencies to consider LGBT rights when issuing financial aid to foreign countries. He also criticized Russia's law discriminating against gays, joining other western leaders in the boycott of the 2014 Winter Olympics in Russia. In June 2014, a Chilean court ruled that the United States played a key role in the murders of Charles Horman and Frank Teruggi, both American citizens, shortly after the 1973 Chilean coup d'état. War on Drugs United States foreign policy is influenced by the efforts of the U.S. government to control imports of illicit drugs, including cocaine, heroin, methamphetamine, and cannabis. This is especially true in Latin America, a focus for the U.S. War on Drugs. Those efforts date back to at least 1880, when the U.S. and China completed an agreement that prohibited the shipment of opium between the two countries. Over a century later, the Foreign Relations Authorization Act requires the President to identify the major drug transit or major illicit drug-producing countries. In September 2005, the following countries were identified: Bahamas, Bolivia, Brazil, Burma, Colombia, Dominican Republic, Ecuador, Guatemala, Haiti, India, Jamaica, Laos, Mexico, Nigeria, Pakistan, Panama, Paraguay, Peru and Venezuela. Two of these, Burma and Venezuela are countries that the U.S. considers to have failed to adhere to their obligations under international counternarcotics agreements during the previous 12 months. Notably absent from the 2005 list were Afghanistan, the People's Republic of China and Vietnam; Canada was also omitted in spite of evidence that criminal groups there are increasingly involved in the production of MDMA destined for the United States and that large-scale cross-border trafficking of Canadian-grown cannabis continues. The U.S. believes that the Netherlands are successfully countering the production and flow of MDMA to the U.S. Criticism Critics from the left cite episodes that undercut leftist governments or showed support for Israel. Others cite human rights abuses and violations of international law. Critics have charged that the U.S. presidents have used democracy to justify military intervention abroad. Critics also point to declassified records which indicate that the CIA under Allen Dulles and the FBI under J. Edgar Hoover aggressively recruited more than 1,000 Nazis, including those responsible for war crimes, to use as spies and informants against the Soviet Union in the Cold War. The U.S. has faced criticism for backing right-wing dictators that systematically violated human rights, such as Augusto Pinochet of Chile, Alfredo Stroessner of Paraguay, Efraín Ríos Montt of Guatemala, Jorge Rafael Videla of Argentina, Hissène Habré of Chad Yahya Khan of Pakistan and Suharto of Indonesia. Critics have also accused the United States of facilitating and supporting state terrorism in the Global South during the Cold War, such as Operation Condor, an international campaign of political assassination and state terror organized by right-wing military dictatorships in the Southern Cone of South America. Journalists and human rights organizations have been critical of US-led airstrikes and targeted killings by drones which have in some cases resulted in collateral damage of civilian populations. In early 2017, the U.S. faced criticism from some scholars, activists and media outlets for dropping 26,171 bombs on seven countries throughout 2016: Syria, Iraq, Afghanistan, Libya, Yemen, Somalia and Pakistan. The U.S. has been accused of complicity in war crimes for backing the Saudi Arabian-led intervention into the Yemeni Civil War, which has triggered a humanitarian catastrophe, including a cholera outbreak and millions facing starvation. Studies have been devoted to the historical success rate of the U.S. in exporting democracy abroad. Some studies of American intervention have been pessimistic about the overall effectiveness of U.S. efforts to encourage democracy in foreign nations. Some scholars have generally agreed with international relations professor Abraham Lowenthal that U.S. attempts to export democracy have been "negligible, often counterproductive, and only occasionally positive". Other studies find U.S. intervention has had mixed results, and another by Hermann and Kegley has found that military interventions have improved democracy in other countries. A 2013 global poll in 68 countries with 66,000 respondents by Win/Gallup found that the U.S. is perceived as the biggest threat to world peace. America's history of non-intervention has been criticized as well. In his World Policy Journal review of Bill Kauffman's 1995 book America First! Its History, Culture, and Politics, Benjamin Schwartz described America's history of isolationism as a "tragedy" and being rooted in Puritan thinking. Support Regarding support for certain anti-Communist dictatorships during the Cold War, a response is that they were seen as a necessary evil, with the alternatives even worse Communist or fundamentalist dictatorships. David Schmitz says this policy did not serve U.S. interests. Friendly tyrants resisted necessary reforms and destroyed the political center (though not in South Korea), while the 'realist' policy of coddling dictators brought a backlash among foreign populations with long memories. Many democracies have voluntary military ties with the United States. See NATO, ANZUS, Treaty of Mutual Cooperation and Security between the United States and Japan, Mutual Defense Treaty with South Korea, and Major non-NATO ally. Those nations with military alliances with the U.S. can spend less on the military since they can count on U.S. protection. This may give a false impression that the U.S. is less peaceful than those nations. Research on the democratic peace theory has generally found that democracies, including the United States, have not made war on one another. There have been U.S. support for coups against some democracies, but for example Spencer R. Weart argues that part of the explanation was the perception, correct or not, that these states were turning into Communist dictatorships. Also important was the role of rarely transparent United States government agencies, who sometimes mislead or did not fully implement the decisions of elected civilian leaders. Empirical studies (see democide) have found that democracies, including the United States, have killed much fewer civilians than dictatorships. Media may be biased against the U.S. regarding reporting human rights violations. Studies have found that The New York Times coverage of worldwide human rights violations predominantly focuses on the human rights violations in nations where there is clear U.S. involvement, while having relatively little coverage of the human rights violations in other nations. For example, the bloodiest war in recent time, involving eight nations and killing millions of civilians, was the Second Congo War, which was almost completely ignored by the media. Niall Ferguson argues that the U.S. is incorrectly blamed for all the human rights violations in nations they have supported. He writes that it is generally agreed that Guatemala was the worst of the US-backed regimes during the Cold War. However, the U.S. cannot credibly be blamed for all the 200,000 deaths during the long Guatemalan Civil War. The U.S. Intelligence Oversight Board writes that military aid was cut for long periods because of such violations, that the U.S. helped stop a coup in 1993, and that efforts were made to improve the conduct of the security services. Today the U.S. states that democratic nations best support U.S. national interests. According to the U.S. State Department, "Democracy is the one national interest that helps to secure all the others. Democratically governed nations are more likely to secure the peace, deter aggression, expand open markets, promote economic development, protect American citizens, combat international terrorism and crime, uphold human and worker rights, avoid humanitarian crises and refugee flows, improve the global environment, and protect human health."

left at the table for the Lord or, for a lost wanderer who may be in need of food or shelter. The supper begins with the breaking of the Christmas wafer known as "opłatek", a custom observed exclusively in Poland and two other countries. The meals must be vegetarian (with the exception of fish) as a sign of fasting and twelve different dishes are made, thus symbolizing the Twelve Apostles. The celebration ends with the exchange of gifts and a midnight mass in churches. Other aspects of Polish Christmas include nativity plays called "Jasełka" or "Herody", outdoor nativity scenes, the singing of carols, most notably "God Is Born", and Kulig, a horse-pulled sleigh ride. The tradition of crafting and hand-making Christmas szopkas in Kraków was declared UNESCO Intangible Cultural Heritage. Advent Among the special tasks carried out in private homes during Advent (a time of waiting for the celebration of the Nativity of Jesus) is the baking of the Christmas piernik (gingerbread), and the making of Christmas decorations. Pierniks are made in a variety of shapes, including hearts, animals, and St. Nicholas figures. St. Nicholas does not play a major role on Christmas Day, but is celebrated on his Saint feast day of December 6. He visits good children in secret and leaves presents for them. Traditionally, the Christmas trees are decorated with glass baubles, garlands and many homemade ornaments including painted eggshells, shiny red apples, walnuts, wrapped chocolate shapes, candles, etc. They are lit on Christmas Eve before Wigilia. At the top of each tree there is a star or a glittering tree topper. In many homes, sparklers are hung on the branches of the trees for wintery ambiance. Sometimes the trees are left standing until February 2, the feast day of St. Mary of the Candle of Lighting. During Advent and all the way until Epiphany, or the baptism of Jesus (day of January 6), the "gwiazdory", or the star carriers walk through the villages. Some of them sing carols; others recite verses or put on "szopki", or "herody" (nativity scenes). The last two customs are inspired by the traditional manger scenes or "Jasełka" (crib). One tradition unique to Poland is the sharing of the "opłatek", a thin wafer into which a holy picture is pressed. In the old days, people carried these wafers from house to house wishing their neighbors a Merry Christmas. Nowadays, opłatek is mostly shared with members of the family and immediate neighbors before the Christmas Eve supper (Wigilia in the Polish language). As each person shares pieces of the wafer with another, they are supposed to forgive each other any hurts that have occurred over the past year and wish them happiness in the coming year. Wigilia, the Christmas Eve supper In Poland, Christmas Eve is a day first of fasting, then of feasting. The Wigilia feast begins at the appearance of the first star. There is no red meat served but fish, usually carp. The supper, which includes many traditional dishes and desserts can sometimes last for over two hours. It is followed by the exchange of gifts. The next day, the Christmas Day, is often spent visiting friends. In Polish tradition, people combine religion and family closeness at Christmas. Although gift-giving plays a major role in the rituals, the emphasis is placed more on the making of special foods and decorations. On the night of Christmas Eve, so important is the appearance of the first star in remembrance of the Star of Bethlehem, that it has been given an affectionate name of "the little star" or Gwiazdka (the female counterpart of St. Nicholas). On that evening, children watch the sky anxiously hoping to be the first to cry out, "The star has come!" Only after it appears, the family members sit down to a dinner table. According to tradition, bits of hay are spread beneath the tablecloth as a reminder that Christ was born in a manger. Others partake in the practice of placing money under the tablecloth for each guest, in order to wish for prosperity in the coming year. Some practice the superstition that an even number of people must be seated around the table. In many homes an empty place setting is symbolically left at the table for the Baby Jesus or, for a lonely wanderer who may be in need of food, or if a deceased relative

the past, and the original ending was considered too depressing for the musical theatre. After acquiring the rights, the team created a work with lengthy sequences of music and made the ending more hopeful. The musical required considerable modification during out-of-town tryouts, but once it opened on Broadway on April 19, 1945, it was an immediate hit with both critics and audiences. Carousel initially ran for 890 performances and duplicated its success in the West End in 1950. Though it has never achieved as much commercial success as Oklahoma!, the piece has been repeatedly revived, recorded several times and was filmed in 1956. A production by Nicholas Hytner enjoyed success in 1992 in London, in 1994 in New York and on tour. Another Broadway revival opened in 2018. In 1999, Time magazine named Carousel the best musical of the 20th century. Background Liliom Ferenc Molnár's Hungarian-language drama, Liliom, premiered in Budapest in 1909. The audience was puzzled by the work, and it lasted only thirty-odd performances before being withdrawn, the first shadow on Molnár's successful career as a playwright. Liliom was not presented again until after World War I. When it reappeared on the Budapest stage, it was a tremendous hit. Except for the ending, the plots of Liliom and Carousel are very similar. Andreas Zavocky (nicknamed Liliom, the Hungarian word for "lily", a slang term for "tough guy"), a carnival barker, falls in love with Julie Zeller, a servant girl, and they begin living together. With both discharged from their jobs, Liliom is discontented and contemplates leaving Julie, but decides not to do so on learning that she is pregnant. A subplot involves Julie's friend Marie, who has fallen in love with Wolf Biefeld, a hotel porter—after the two marry, he becomes the owner of the hotel. Desperate to make money so that he, Julie and their child can escape to America and a better life, Liliom conspires with lowlife Ficsur to commit a robbery, but it goes badly, and Liliom stabs himself. He dies, and his spirit is taken to heaven's police court. As Ficsur suggested while the two waited to commit the crime, would-be robbers like them do not come before God Himself. Liliom is told by the magistrate that he may go back to Earth for one day to attempt to redeem the wrongs he has done to his family, but must first spend sixteen years in a fiery purgatory. On his return to Earth, Liliom encounters his daughter, Louise, who like her mother is now a factory worker. Saying that he knew her father, he tries to give her a star he stole from the heavens. When Louise refuses to take it, he strikes her. Not realizing who he is, Julie confronts him, but finds herself unable to be angry with him. Liliom is ushered off to his fate, presumably Hell, and Louise asks her mother if it is possible to feel a hard slap as if it was a kiss. Julie reminiscently tells her daughter that it is very possible for that to happen. An English translation of Liliom was credited to Benjamin "Barney" Glazer, though there is a story that the actual translator, uncredited, was Rodgers' first major partner Lorenz Hart. The Theatre Guild presented it in New York City in 1921, with Joseph Schildkraut as Liliom, and the play was a success, running 300 performances. A 1940 revival with Burgess Meredith and Ingrid Bergman was seen by both Hammerstein and Rodgers. Glazer, in introducing the English translation of Liliom, wrote of the play's appeal: And where in modern dramatic literature can such pearls be matched—Julie incoherently confessing to her dead lover the love she had always been ashamed to tell; Liliom crying out to the distant carousel the glad news that he is to be a father; the two thieves gambling for the spoils of their prospective robbery; Marie and Wolf posing for their portrait while the broken-hearted Julie stands looking after the vanishing Liliom, the thieves' song ringing in her ears; the two policemen grousing about pay and pensions while Liliom lies bleeding to death; Liliom furtively proffering his daughter the star he has stolen for her in heaven. ... The temptation to count the whole scintillating string is difficult to resist. Inception In the 1920s and 1930s, Rodgers and Hammerstein both became well known for creating Broadway hits with other partners. Rodgers, with Lorenz Hart, had produced a string of over two dozen musicals, including such popular successes as Babes in Arms (1937), The Boys from Syracuse (1938) and Pal Joey (1940). Some of Rodgers' work with Hart broke new ground in musical theatre: On Your Toes was the first use of ballet to sustain the plot (in the "Slaughter on Tenth Avenue" scene), while Pal Joey flouted Broadway tradition by presenting a knave as its hero. Hammerstein had written or co-written the words for such hits as Rose-Marie (1924), The Desert Song (1926), The New Moon (1927) and Show Boat (1927). Though less productive in the 1930s, he wrote material for musicals and films, sharing an Oscar for his song with Jerome Kern, "The Last Time I Saw Paris", which was included in the 1941 film Lady Be Good. By the early 1940s, Hart had sunk into alcoholism and emotional turmoil, becoming unreliable and prompting Rodgers to approach Hammerstein to ask if he would consider working with him. Hammerstein was eager to do so, and their first collaboration was Oklahoma! (1943). Thomas Hischak states, in his The Rodgers and Hammerstein Encyclopedia, that Oklahoma! is "the single most influential work in the American musical theatre. In fact, the history of the Broadway musical can accurately be divided into what came before Oklahoma! and what came after it." An innovation for its time in integrating song, character, plot and dance, Oklahoma! would serve, according to Hischak, as "the model for Broadway shows for decades", and proved a huge popular and financial success. Once it was well-launched, what to do as an encore was a daunting challenge for the pair. Film producer Samuel Goldwyn saw Oklahoma! and advised Rodgers to shoot himself, which according to Rodgers "was Sam's blunt but funny way of telling me that I'd never create another show as good as Oklahoma!" As they considered new projects, Hammerstein wrote, "We're such fools. No matter what we do, everyone is bound to say, 'This is not another Oklahoma! " Oklahoma! had been a struggle to finance and produce. Hammerstein and Rodgers met weekly in 1943 with Theresa Helburn and Lawrence Langner of the Theatre Guild, producers of the blockbuster musical, who together formed what they termed "the Gloat Club". At one such luncheon, Helburn and Langner proposed to Rodgers and Hammerstein that they turn Molnár's Liliom into a musical. Both men refused—they had no feeling for the Budapest setting and thought that the unhappy ending was unsuitable for musical theatre. In addition, given the unstable wartime political situation, they might need to change the setting from Hungary while in rehearsal. At the next luncheon, Helburn and Langner again proposed Liliom, suggesting that they move the setting to Louisiana and make Liliom a Creole. Rodgers and Hammerstein played with the idea over the next few weeks, but decided that Creole dialect, filled with "zis" and "zose", would sound corny and would make it difficult to write effective lyrics. A breakthrough came when Rodgers, who owned a house in Connecticut, proposed a New England setting. Hammerstein wrote of this suggestion in 1945, I began to see an attractive ensemble—sailors, whalers, girls who worked in the mills up the river, clambakes on near-by islands, an amusement park on the seaboard, things people could do in crowds, people who were strong and alive and lusty, people who had always been depicted on the stage as thin-lipped puritans—a libel I was anxious to refute ... as for the two leading characters, Julie with her courage and inner strength and outward simplicity seemed more indigenous to Maine than to Budapest. Liliom is, of course, an international character, indigenous to nowhere. Rodgers and Hammerstein were also concerned about what they termed "the tunnel" of Molnár's second act—a series of gloomy scenes leading up to Liliom's suicide—followed by a dark ending. They also felt it would be difficult to set Liliom's motivation for the robbery to music. Molnár's opposition to having his works adapted was also an issue; he had famously turned down Giacomo Puccini when the great composer wished to transform Liliom into an opera, stating that he wanted the piece to be remembered as his, not Puccini's. In 1937, Molnár, who had recently emigrated to the United States, had declined another offer from Kurt Weill to adapt the play into a musical. The pair continued to work on the preliminary ideas for a Liliom adaptation while pursuing other projects in late 1943 and early 1944—writing the film musical State Fair and producing I Remember Mama on Broadway. Meanwhile, the Theatre Guild took Molnár to see Oklahoma! Molnár stated that if Rodgers and Hammerstein could adapt Liliom as beautifully as they had modified Green Grow the Lilacs into Oklahoma!, he would be pleased to have them do it. The Guild obtained the rights from Molnár in October 1943. The playwright received one percent of the gross and $2,500 for "personal services". The duo insisted, as part of the contract, that Molnár permit them to make changes in the plot. At first, the playwright refused, but eventually yielded. Hammerstein later stated that if this point had not been won, "we could never have made Carousel." In seeking to establish through song Liliom's motivation for the robbery, Rodgers remembered that he and Hart had a similar problem in Pal Joey. Rodgers and Hart had overcome the problem with a song that Joey sings to himself, "I'm Talking to My Pal". This inspired "Soliloquy". Both partners later told a story that "Soliloquy" was only intended to be a song about Liliom's dreams of a son, but that Rodgers, who had two daughters, insisted that Liliom consider that Julie might have a girl. However, the notes taken at their meeting of December 7, 1943 state: "Mr. Rodgers suggested a fine musical number for the end of the scene where Liliom discovers he is to be a father, in which he sings first with pride of the growth of a boy, and then suddenly realizes it might be a girl and changes completely." Hammerstein and Rodgers returned to the Liliom project in mid-1944. Hammerstein was uneasy as he worked, fearing that no matter what they did, Molnár would disapprove of the results. Green Grow the Lilacs had been a little-known work; Liliom was a theatrical standard. Molnár's text also contained considerable commentary on the Hungarian politics of 1909 and the rigidity of that society. A dismissed carnival barker who hits his wife, attempts a robbery and commits suicide seemed an unlikely central character for a musical comedy. Hammerstein decided to use the words and story to make the audience sympathize with the lovers. He also built up the secondary couple, who are incidental to the plot in Liliom; they became Enoch Snow and Carrie Pipperidge. "This Was a Real Nice Clambake" was repurposed from a song, "A Real Nice Hayride", written for Oklahoma! but not used. Molnár's ending was unsuitable, and after a couple of false starts, Hammerstein conceived the graduation scene that ends the musical. According to Frederick Nolan in his book on the team's works: "From that scene the song "You'll Never Walk Alone" sprang almost naturally." In spite of Hammerstein's simple lyrics for "You'll Never Walk Alone", Rodgers had great difficulty in setting it to music. Rodgers explained his rationale for the changed ending, Liliom was a tragedy about a man who cannot learn to live with other people. The way Molnár wrote it, the man ends up hitting his daughter and then having to go back to purgatory, leaving his daughter helpless and hopeless. We couldn't accept that. The way we ended Carousel it may still be a tragedy but it's a hopeful one because in the final scene it is clear that the child has at last learned how to express herself and communicate with others. When the pair decided to make "This Was a Real Nice Clambake" into an ensemble number, Hammerstein realized he had no idea what a clambake was like, and researched the matter. Based on his initial findings, he wrote the line, "First came codfish chowder". However, further research convinced him the proper term was "codhead chowder", a term unfamiliar to many playgoers. He decided to keep it as "codfish". When the song proceeded to discuss the lobsters consumed at the feast, Hammerstein wrote the line "We slit 'em down the back/And peppered 'em good". He was grieved to hear from a friend that lobsters are always slit down the front. The lyricist sent a researcher to a seafood restaurant and heard back that lobsters are always slit down the back. Hammerstein concluded that there is disagreement about which side of a lobster is the back. One error not caught involved the song "June Is Bustin' Out All Over", in which sheep are depicted as seeking to mate in late spring—they actually do so in the winter. Whenever this was brought to Hammerstein's attention, he told his informant that 1873 was a special year, in which sheep mated in the spring. Rodgers early decided to dispense with an overture, feeling that the music was hard to hear over the banging of seats as latecomers settled themselves. In his autobiography, Rodgers complained that only the brass section can be heard during an overture because there are never enough strings in a musical's small orchestra. He determined to force the audience to concentrate from the beginning by opening with a pantomime scene accompanied by what became known as "The Carousel Waltz". The pantomime paralleled one in the Molnár play, which was also used to introduce the characters and situation to the audience. Author Ethan Mordden described the effectiveness of this opening: Other characters catch our notice—Mr. Bascombe, the pompous mill owner, Mrs. Mullin, the widow who runs the carousel and, apparently, Billy; a dancing bear; an acrobat. But what draws us in is the intensity with which Julie regards Billy—the way she stands frozen, staring at him, while everyone else at the fair is swaying to the rhythm of Billy's spiel. And as Julie and Billy ride together on the swirling carousel, and the stage picture surges with the excitement of the crowd, and the orchestra storms to a climax, and the curtain falls, we realize that R & H have not only skipped the overture and the opening number but the exposition as well. They have plunged into the story, right into the middle of it, in the most intense first scene any musical ever had. Casting and out-of-town tryouts The casting for Carousel began when Oklahoma!s production team, including Rodgers and Hammerstein, was seeking a replacement for the part of Curly (the male lead in Oklahoma!). Lawrence Langner had heard, through a relative, of a California singer named John Raitt, who might be suitable for the part. Langner went to hear Raitt, then urged the others to bring Raitt to New York for an audition. Raitt asked to sing "Largo al factotum", Figaro's aria from The Barber of Seville, to warm up. The warmup was sufficient to convince the producers that not only had they found a Curly, they had found a Liliom (or Billy Bigelow, as the part was renamed). Theresa Helburn made another California discovery, Jan Clayton, a singer/actress who had made a few minor films for MGM. She was brought east and successfully auditioned for the part of Julie. The producers sought to cast unknowns. Though many had played in previous Hammerstein or Rodgers works, only one, Jean Casto (cast as carousel owner Mrs. Mullin, and a veteran of Pal Joey), had ever played on Broadway before. It proved harder to cast the ensemble than the leads, due to the war—Rodgers told his casting director, John Fearnley, that the sole qualification for a dancing boy was that he be alive. Rodgers and Hammerstein reassembled much of the creative team that had made Oklahoma! a success, including director Rouben Mamoulian and choreographer Agnes de Mille. Miles White was the costume designer while Jo Mielziner (who had not worked on Oklahoma!) was the scenic and lighting designer. Even though Oklahoma! orchestrator Russell Bennett had informed Rodgers that he was unavailable to work on Carousel due to a radio contract, Rodgers insisted he do the work in his spare time. He orchestrated "The Carousel Waltz" and "(When I Marry) Mister Snow" before finally being replaced by Don Walker. A new member of the creative team was Trude Rittmann, who arranged the dance music. Rittmann initially felt that Rodgers mistrusted her because she was a woman, and found him difficult to work with, but the two worked together on Rodgers' shows until the 1970s. Rehearsals began in January 1945; either Rodgers or Hammerstein was always present. Raitt was presented with the lyrics for "Soliloquy" on a five-foot long sheet of paper—the piece ran nearly eight minutes. Staging such a long solo number presented problems, and Raitt later stated that he felt that they were never fully addressed. At some point during rehearsals, Molnár came to see what they had done to his play. There are a number of variations on the story.Fordin, pp. 231–32 As Rodgers told it, while watching rehearsals with Hammerstein, the composer spotted Molnár in the rear of the theatre and whispered the news to his partner. Both sweated through an afternoon of rehearsal in which nothing seemed to go right. At the end, the two walked to the back of the theatre, expecting an angry reaction from Molnár. Instead, the playwright said enthusiastically, "What you have done is so beautiful. And you know what I like best? The ending!" Hammerstein wrote that Molnár became a regular attendee at rehearsals after that. Like most of the pair's works, Carousel contains a lengthy ballet, "Billy Makes a Journey", in the second act, as Billy looks down to the Earth from "Up There" and observes his daughter. In the original production the ballet was choreographed by de Mille. It began with Billy looking down from heaven at his wife in labor, with the village women gathered for a "birthing". The ballet involved every character in the play, some of whom spoke lines of dialogue, and contained a number of subplots. The focus was on Louise, played by Bambi Linn, who at first almost soars in her dance, expressing the innocence of childhood. She is teased and mocked by her schoolmates, and Louise becomes attracted to the rough carnival people, who symbolize Billy's world. A youth from the carnival attempts to seduce Louise, as she discovers her own sexuality, but he decides she is more girl than woman, and he leaves her. After Julie comforts her, Louise goes to a children's party, where she is shunned. The carnival people reappear and form a ring around the children's party, with Louise lost between the two groups. At the end, the performers form a huge carousel with their bodies. The play opened for tryouts in New Haven, Connecticut on March 22, 1945. The first act was well-received; the second act was not. Casto recalled that the second act finished about 1:30 a.m. The staff immediately sat down for a two-hour conference. Five scenes, half the ballet, and two songs were cut from the show as the result. John Fearnley commented, "Now I see why these people have hits. I never witnessed anything so brisk and brave in my life." De Mille said of this conference, "not three minutes had been wasted pleading for something cherished. Nor was there any idle joking. ... We cut and cut and cut and then we went to bed." By the time the company left New Haven, de Mille's ballet was down to forty minutes. A major concern with the second act was the effectiveness of the characters He and She (later called by Rodgers "Mr. and Mrs. God"), before whom Billy appeared after his death. Mr. and Mrs. God were depicted as a New England minister and his wife, seen in their parlor.Block (ed.), p. 129. At this time, according to the cast sheet distributed during the Boston run, Dr. Seldon was listed as the "Minister". The couple was still part of the show at the Boston opening. Rodgers said to Hammerstein, "We've got to get God out of that parlor". When Hammerstein inquired where he should put the deity, Rodgers replied, "I don't care where you put Him. Put Him on a ladder for all I care, only get Him out of that parlor!" Hammerstein duly put Mr. God (renamed the Starkeeper) atop a ladder, and Mrs. God was removed from the show. Rodgers biographer Meryle Secrest terms this change a mistake, leading to a more fantastic afterlife, which was later criticized by The New Republic as "a Rotarian atmosphere congenial to audiences who seek not reality but escape from reality, not truth but escape from truth". Hammerstein wrote that Molnár's advice, to combine two scenes into one, was key to pulling together the second act and represented "a more radical departure from the original than any change we had made". A reprise of "If I Loved You" was added in the second act, which Rodgers felt needed more music. Three weeks of tryouts in Boston followed the brief New Haven run, and the audience there gave the musical a warm reception. An even shorter version of the ballet was presented the final two weeks in Boston, but on the final night there, de Mille expanded it back to forty minutes, and it brought the house down, causing both Rodgers and Hammerstein to embrace her. Synopsis Act 1 Two young female millworkers in 1873 Maine visit the town's carousel after work. One of them, Julie Jordan, attracts the attention of the barker, Billy Bigelow ("The Carousel Waltz"). When Julie lets Billy put his arm around her during the ride, Mrs. Mullin, the widowed owner of the carousel, tells Julie never to return. Julie and her friend, Carrie Pipperidge, argue with Mrs. Mullin. Billy arrives and, seeing that Mrs. Mullin is jealous, mocks her; he is fired from his job. Billy, unconcerned, invites Julie to join him for a drink. As he goes to get his belongings, Carrie presses Julie about her feelings toward him, but Julie is evasive ("You're a Queer One, Julie Jordan"). Carrie has a beau too, fisherman Enoch Snow ("(When I Marry)

When Julie lets Billy put his arm around her during the ride, Mrs. Mullin, the widowed owner of the carousel, tells Julie never to return. Julie and her friend, Carrie Pipperidge, argue with Mrs. Mullin. Billy arrives and, seeing that Mrs. Mullin is jealous, mocks her; he is fired from his job. Billy, unconcerned, invites Julie to join him for a drink. As he goes to get his belongings, Carrie presses Julie about her feelings toward him, but Julie is evasive ("You're a Queer One, Julie Jordan"). Carrie has a beau too, fisherman Enoch Snow ("(When I Marry) Mister Snow"), to whom she is newly engaged. Billy returns for Julie as the departing Carrie warns that staying out late means the loss of Julie's job. Mr. Bascombe, owner of the mill, happens by along with a policeman, and offers to escort Julie to her home, but she refuses and is fired. Left alone, she and Billy talk about what life might be like if they were in love, but neither quite confesses to the growing attraction they feel for each other ("If I Loved You"). Over a month passes, and preparations for the summer clambake are under way ("June Is Bustin' Out All Over"). Julie and Billy, now married, live at Julie's cousin Nettie's spa. Julie confides in Carrie that Billy, frustrated over being unemployed, hit her. Carrie has happier news—she is engaged to Enoch, who enters as she discusses him ("(When I Marry) Mister Snow (reprise))". Billy arrives with his ne'er-do-well whaler friend, Jigger. The former barker is openly rude to Enoch and Julie, then leaves with Jigger, followed by a distraught Julie. Enoch tells Carrie that he expects to become rich selling herring and to have a large family, larger perhaps than Carrie is comfortable having ("When the Children Are Asleep"). Jigger and his shipmates, joined by Billy, then sing about life on the sea ("Blow High, Blow Low"). The whaler tries to recruit Billy to help with a robbery, but Billy declines, as the victim—Julie's former boss, Mr. Bascombe—might have to be killed. Mrs. Mullin enters and tries to tempt Billy back to the carousel (and to her). He would have to abandon Julie; a married barker cannot evoke the same sexual tension as one who is single. Billy reluctantly mulls it over as Julie arrives and the others leave. She tells him that she is pregnant, and Billy is overwhelmed with happiness, ending all thoughts of returning to the carousel. Once alone, Billy imagines the fun he will have with Bill Jr.—until he realizes that his child might be a girl, and reflects soberly that "you've got to be a father to a girl" ("Soliloquy"). Determined to provide financially for his future child, whatever the means, Billy decides to be Jigger's accomplice. The whole town leaves for the clambake. Billy, who had earlier refused to go, agrees to join in, to Julie's delight, as he realizes that being seen at the clambake is integral to his and Jigger's alibi ("Act I Finale"). Act 2 Everyone reminisces about the huge meal and much fun ("This Was a Real Nice Clambake"). Jigger tries to seduce Carrie; Enoch walks in at the wrong moment, and declares that he is finished with her ("Geraniums In the Winder"), as Jigger jeers ("There's Nothin' So Bad for a Woman"). The girls try to comfort Carrie, but for Julie all that matters is that "he's your feller and you love him" ("What's the Use of Wond'rin'?"). Julie sees Billy trying to sneak away with Jigger and, trying to stop him, feels the knife hidden in his shirt. She begs him to give it to her, but he refuses and leaves to commit the robbery. As they wait, Jigger and Billy gamble with cards. They stake their shares of the anticipated robbery spoils. Billy loses: his participation is now pointless. Unknown to Billy and Jigger, Mr. Bascombe, the intended victim, has already deposited the mill's money. The robbery fails: Bascombe pulls a gun on Billy while Jigger escapes. Billy stabs himself with his knife; Julie arrives just in time for him to say his last words to her and die. Julie strokes his hair, finally able to tell him that she loved him. Carrie and Enoch, reunited by the crisis, attempt to console Julie; Nettie arrives and gives Julie the resolve to keep going despite her despair ("You'll Never Walk Alone"). Billy's defiant spirit ("The Highest Judge of All") is taken Up There to see the Starkeeper, a heavenly official. The Starkeeper tells Billy that the good he did in life was not enough to get into heaven, but so long as there is a person alive who remembers him, he can return for a day to try to do good to redeem himself. He informs Billy that fifteen years have passed on Earth since his suicide, and suggests that Billy can get himself into heaven if he helps his daughter, Louise. He helps Billy look down from heaven to see her (instrumental ballet: "Billy Makes a Journey"). Louise has grown up to be lonely and bitter. The local children ostracize her because her father was a thief and a wife-beater. In the dance, a young ruffian, much like her father at that age, flirts with her and abandons her as too young. The dance concludes, and Billy is anxious to return to Earth and help his daughter. He steals a star to take with him, as the Starkeeper pretends not to notice. Outside Julie's cottage, Carrie describes her visit to New York with the now-wealthy Enoch. Carrie's husband and their many children enter to fetch her—the family must get ready for the high school graduation later that day. Enoch Jr., the oldest son, remains behind to talk with Louise, as Billy and the Heavenly Friend escorting him enter, invisible to the other characters. Louise confides in Enoch Jr. that she plans to run away from home with an acting troupe. He says that he will stop her by marrying her, but that his father will think her an unsuitable match. Louise is outraged: each insults the other's father, and Louise orders Enoch Jr. to go away. Billy, able to make himself visible at will, reveals himself to the sobbing Louise, pretending to be a friend of her father. He offers her a gift—the star he stole from heaven. She refuses it and, frustrated, he slaps her hand. He makes himself invisible, and Louise tells Julie what happened, stating that the slap miraculously felt like a kiss, not a blow—and Julie understands her perfectly. Louise retreats to the house, as Julie notices the star that Billy dropped; she picks it up and seems to feel Billy's presence ("If I Loved You (Reprise)"). Billy invisibly attends Louise's graduation, hoping for one last chance to help his daughter and redeem himself. The beloved town physician, Dr. Seldon (who resembles the Starkeeper) advises the graduating class not to rely on their parents' success or be held back by their failure (words directed at Louise). Seldon prompts everyone to sing an old song, "You'll Never Walk Alone". Billy, still invisible, whispers to Louise, telling her to believe Seldon's words, and when she tentatively reaches out to another girl, she learns she does not have to be an outcast.

The dress rehearsal the day before had gone badly, and the pair feared the new work would not be well received. One successful last-minute change was to have de Mille choreograph the pantomime. The movement of the carnival crowd in the pantomime had been entrusted to Mamoulian, and his version was not working. Rodgers had injured his back the previous week, and he watched the opening from a stretcher propped in a box behind the curtain. Sedated with morphine, he could see only part of the stage. As he could not hear the audience's applause and laughter, he assumed the show was a failure. It was not until friends congratulated him later that evening that he realized that the curtain had been met by wild applause. Bambi Linn, who played Louise, was so enthusiastically received by the audience during her ballet that she was forced to break character, when she next appeared, and bow. Rodgers' daughter Mary caught sight of her friend, Stephen Sondheim, both teenagers then, across several rows; both had eyes wet with tears. The original production ran for 890 performances, closing on May 24, 1947. The original cast included John Raitt (Billy), Jan Clayton (Julie), Jean Darling (Carrie), Eric Mattson (Enoch Snow), Christine Johnson (Nettie Fowler), Murvyn Vye (Jigger), Bambi Linn (Louise) and Russell Collins (Starkeeper). In December 1945, Clayton left to star in the Broadway revival of Show Boat and was replaced by Iva Withers; Raitt was replaced by Henry Michel in January 1947; Darling was replaced by Margot Moser.Hischak, p. 62 After closing on Broadway, the show went on a national tour for two years. It played for five months in Chicago alone, visited twenty states and two Canadian cities, covered and played to nearly two million people. The touring company had a four-week run at New York City Center in January 1949. Following the City Center run, the show was moved back to the Majestic Theatre in the hopes of filling the theatre until South Pacific opened in early April. However, ticket sales were mediocre, and the show closed almost a month early. The musical premiered in the West End, London, at the Theatre Royal, Drury Lane on June 7, 1950. The production was restaged by Jerome Whyte, with a cast that included Stephen Douglass (Billy), Iva Withers (Julie) and Margot Moser (Carrie). Carousel ran in London for 566 performances, remaining there for over a year and a half. Subsequent productions Carousel was revived in 1954 and 1957 at City Center, presented by the New York City Center Light Opera Company. Both times, the production featured Barbara Cook, though she played Carrie in 1954 and Julie in 1957 (playing alongside Howard Keel as Billy). The production was then taken to Belgium to be performed at the 1958 Brussels World's Fair, with David Atkinson as Billy, Ruth Kobart as Nettie, and Clayton reprising the role of Julie, which she had originated. In August 1965, Rodgers and the Music Theater of Lincoln Center produced Carousel for 47 performances. John Raitt reprised the role of Billy, with Jerry Orbach as Jigger and Reid Shelton as Enoch Snow. The roles of the Starkeeper and Dr. Seldon were played by Edward Everett Horton in his final stage appearance. The following year, New York City Center Light Opera Company brought Carousel back to City Center for 22 performances, with Bruce Yarnell as Billy and Constance Towers as Julie. Nicholas Hytner directed a new production of Carousel in 1992, at London's Royal National Theatre, with choreography by Sir Kenneth MacMillan and designs by Bob Crowley. In this staging, the story begins at the mill, where Julie and Carrie work, with the music slowed down to emphasize the drudgery. After work ends, they move to the shipyards and then to the carnival. As they proceed on a revolving stage, carnival characters appear, and at last the carousel is assembled onstage for the girls to ride.Block, p. 175 Louise is seduced by the ruffian boy during her Act 2 ballet, set around the ruins of a carousel. Michael Hayden played Billy not as a large, gruff man, but as a frustrated smaller one, a time bomb waiting to explode. Hayden, Joanna Riding (Julie) and Janie Dee (Carrie) all won Olivier Awards for their performances. Patricia Routledge played Nettie. Enoch and Carrie were cast as an interracial couple whose eight children, according to the review in The New York Times, looked like "a walking United Colors of Benetton ad". Clive Rowe, as Enoch, was nominated for an Olivier Award. The production's limited run from December 1992 through March 1993 was a sellout. It re-opened at the Shaftesbury Theatre in London in September

Theatrical work Barker's involvement in live theatre began while still in school with productions of Voodoo and Inferno in 1967. He collaborated on six plays with Theatre of the Imagination in 1974 and two more that he was the sole writer of, A Clowns' Sodom and Day of the Dog, for The Mute Pantomime Theatre in 1976 and 1977. He co-founded the avant-garde theatrical troupe The Dog Company in 1978 with former school friends and up and coming actors, many of which would go on to become key collaborators in Barker's film work. Doug Bradley would take on the iconic role of Pinhead in the Hellraiser series while Peter Atkins would write the scripts for the first three Hellraiser sequels. Over the next five years Barker would write nine plays, often serving as director, including some of his most well-known stage productions, The History of The Devil, Frankenstein in Love, and The Secret Life of Cartoons. From 1982 to 1983, he also created three plays, including Crazyface, for the Cockpit Youth Theatre. His theatrical work would come to a close as he shifted focus to writing the Books of Blood. Writing career Barker is an author of horror and fantasy. He began writing horror early in his career, mostly in the form of short stories (collected in Books of Blood 1–6) and the Faustian novel The Damnation Game (1985). Later he moved toward modern-day fantasy and urban fantasy with horror elements in Weaveworld (1987), The Great and Secret Show (1989), the world-spanning Imajica (1991), and Sacrament (1996). When Books of Blood was first published in the United States in paperback, Stephen King was quoted on the book covers: "I have seen the future of horror and his name is Clive Barker." As influences on his writing, Barker lists Herman Melville, Edgar Allan Poe, Ray Bradbury, William S. Burroughs, William Blake, and Jean Cocteau, among others. He is the writer of the best-selling Abarat series. Personal life During his early years as a writer, he would occasionally work as a male prostitute when his writing did not provide sufficient income. In 2003, Barker received the Davidson/Valentini Award at the 15th GLAAD Media Awards. Barker is critical of organized religion, but has said that the Bible influences his work and spirituality. In a 2003 appearance on Politically Incorrect, Barker said that he was a Christian after Ann Coulter implied he was not, although years later, he said he does not identify as a Christian via Facebook. Barker said in a December 2008 online interview (published in March 2009) that he had polyps in his throat which were so severe that a doctor told him he was taking in ten percent of the air he was supposed to have been getting. He has had two surgeries to remove them and believes his resultant voice is an improvement over how it was prior to the surgeries. He said he did not have cancer and has given up cigars. In 2012, Barker went into a coma for several days after having contracted toxic shock syndrome, triggered by a visit to the dentist which unloaded a spillage of poisonous bacteria into his bloodstream, almost claiming his life. Realising he might have just a short time left to live, he decided to put his personal concerns about the world and society into the upcoming novel Deep Hill, which he then thought could be his final book. As of 2015, he is a member of the board of advisers for the Hollywood Horror Museum. Relationships While appearing on the radio call-in show Loveline on 20 August 1996, Barker stated that during his teens he had several relationships with older women, but came to identify himself as homosexual by 18 or 19 years old. His relationship with John Gregson lasted from 1975 until 1986. He later spent 13 years with photographer David Armstrong, described as his husband in the introduction to Coldheart Canyon; they separated in 2009. Film work Barker wrote the screenplays for Underworld (1985) and Rawhead Rex (1986), both directed by George Pavlou. Displeased by how his material was handled, he moved to directing with Hellraiser (1987), based on his novella The Hellbound Heart. After his film Nightbreed (1990) flopped, Barker returned to write and direct Lord of Illusions (1995). The short story "The Forbidden", from Barker's Books of Blood, provided the basis for the 1992 film Candyman and its three sequels. He had been working on a series of film adaptations of his The Abarat Quintet books under The Walt Disney Company's management, but due to creative differences, the project was cancelled. He served as an executive producer for the 1998 film Gods and Monsters, a semi-fictional tale of Frankenstein director James Whale's later years, which won an Academy Award for Best Adapted Screenplay. Barker said of his interest in the project: "Whale was gay, I'm gay; Whale was English, I'm English…Whale made some horror movies, and I've made some
United States as well as within his own books. He has created original characters and series for comic books, and some of his more popular horror stories have been featured in ongoing comics series. Early life Barker was born in Liverpool, the son of Joan Ruby (née Revill), a painter and school welfare officer, and Leonard Barker, a personnel director for an industrial relations firm. He was educated at Dovedale Primary School, Quarry Bank High School and the University of Liverpool, where he studied English and philosophy. When he was three years old, Barker witnessed the French skydiver Léo Valentin plummet to his death during a performance at an air show in Liverpool. Barker would later allude to Valentin in many of his stories. Theatrical work Barker's involvement in live theatre began while still in school with productions of Voodoo and Inferno in 1967.

Humorous fantasies narrated in a "gentleman's club" setting are common; they include John Kendrick Bangs' A Houseboat on the Styx (1895), Lord Dunsany's "Jorkens" stories, and Maurice Richardson's The Exploits of Englebrecht (1950). According to Lin Carter, T. H. White's works exemplify fantasy comedy, L. Sprague de Camp and Fletcher Pratt's Harold Shea stories are early exemplars. The overwhelming bulk of de Camp's fantasy was comic. Pratt and de Camp were among several contributors to Unknown Worlds, a pulp magazine which emphasized fantasy with a comedic element. The work of Fritz Leiber also appeared in Unknown Worlds, including his Fafhrd and the Gray Mouser stories, a jocose take on the sword and sorcery subgenre. In more modern times, Terry Pratchett's Discworld books, Piers Anthony's Xanth books, Robert Asprin's MythAdventures of Skeeve and Aahz books, and Tom Holt's books provide good examples, as do many of the works by Christopher Moore. There are also comic-strips/graphic novels in the humorous fantasy genre, including Chuck Whelon's Pewfell series and the webcomics 8-Bit Theater and The Order of the Stick. Other recent authors in the genre include Toby Frost, Stuart Sharp, Nicholas Andrews, and DC Farmer, and the writing team of John P. Logsdon and Christopher P. Young.

concept of a cluster, CLU's type extension system and the root of the language's name (CLUster). Clusters correspond generally to the concept of a "class" in an OO language. For instance, here is the CLU syntax for a cluster that implements complex numbers: complex_number = cluster is add, subtract, multiply, ... rep = record [ real_part: real, imag_part: real ] add = proc ... end add; subtract = proc ... end subtract; multiply = proc ... end multiply; ... end complex_number; A cluster is a module that encapsulates all of its components except for those explicitly named in the "is" clause. These correspond to the public components of a class in recent OO languages. A cluster also defines a type that can be named outside the cluster (in this case, "complex_number"), but its representation type (rep) is hidden from external clients. Cluster names are global, and no namespace mechanism was provided to group clusters or allow them to be created "locally" inside other clusters. CLU does not perform implicit type conversions. In a cluster, the explicit type conversions up and down change between the abstract type and the representation. There is a universal type any, and a procedure force[] to check that an object is a certain type. Objects may be mutable or immutable, the latter being base types such as integers, booleans, characters and strings. Other features Another key feature of the CLU type system are iterators, which return objects from a collection serially, one after another. Iterators offer an identical application programming interface (API) no matter what data they are being used with. Thus the iterator for a collection of complex_numbers can be used interchangeably with that for an array of integers. A distinctive feature of CLU iterators is that they are implemented as coroutines, with each value being provided to the caller via a yield statement. Iterators like those in CLU are now a common feature of many modern languages, such as C#, Ruby, and Python, though recently they are often referred to as generators. CLU also includes exception handling, based on various attempts in other languages; exceptions are raised using signal and handled with except. Unlike most other languages with exception handling, exceptions are not

CLU also includes exception handling, based on various attempts in other languages; exceptions are raised using signal and handled with except. Unlike most other languages with exception handling, exceptions are not implicitly resignaled up the calling chain. Also unlike most other languages that provide exception handling, exceptions in CLU are considered part of ordinary execution flow and are considered a "normal" and efficient typesafe way to break out of loops or return from functions; this allows for direct assignment of return values "except when" other conditions apply. Exceptions that are neither caught nor resignaled explicitly are immediately converted into a special failure exception that typically terminates the program. CLU is often credited as being the first language with type-safe variant types, called oneofs, before the language ML had them. A final distinctive feature in CLU is parallel assignment (multiple assignment), where more than one variable can appear on the left hand side of an assignment operator. For instance, writing x,y := y,x would exchange values of x and y. In the same way, functions could return several values, like . Parallel assignment (though not multiple return values) predates CLU, appearing in CPL (1963), named simultaneous
20 years his senior. Reagan and Gorbachev met for the first time in Geneva in November. The three weeks preceding the summit meeting were marked by an unprecedented Soviet media campaign against the Strategic Defense Initiative (SDI), taking advantage of opposition at home in the US to the program. When it finally took place, the two superpower leaders established a solid rapport that boded well for the future despite Reagan's refusal to compromise on abandonment of SDI. A joint communique by both parties stated that they were in agreement that nuclear war could not be won by either side and must never be allowed to happen. It was also agreed that Reagan and Gorbachev would carry out two more summit meetings in 1986–87. Jimmy Carter had decisively ended the policy of détente, by financially aiding the Mujahideen movement in neighboring Socialist Afghanistan, which served as a pretext for the Soviet intervention in Afghanistan six months later, with the aims of supporting the Afghan government, controlled by the People's Democratic Party of Afghanistan. Tensions between the superpowers increased during this time, when Carter placed trade embargoes on the Soviet Union and stated that the Soviet invasion of Afghanistan was "the most serious threat to the peace since the Second World War." Economy East-West tensions increased during the first term of US President Ronald Reagan (1981–85), reaching levels not seen since the Cuban Missile Crisis as Reagan increased US military spending to 7% of the GDP. To match the military buildup, the Soviet Union increased its own military spending to 27% of its GDP and froze production of civilian goods at 1980 levels, causing a sharp economic decline in the already failing Soviet economy. The US financed the training for the Mujahideen warlords such as Jalaluddin Haqqani, Gulbudin Hekmatyar and Burhanuddin Rabbani eventually culminated to the fall of the Soviet satellite the Democratic Republic of Afghanistan. While the CIA and MI6 and the People's Liberation Army of China financed the operation along with the Pakistan government against the Soviet Union, eventually the Soviet Union began looking for a withdrawal route and in 1988 the Geneva Accords were signed between Communist-Afghanistan and the Islamic Republic of Pakistan; under the terms Soviet troops were to withdraw. Once the withdrawal was complete the Pakistan ISI continued to support the Mujahideen against the Communist Government and by 1992, the government collapsed. US President Reagan also actively hindered the Soviet Union's ability to sell natural gas to Europe whilst simultaneously actively working to keep gas prices low, which kept the price of Soviet oil low and further starved the Soviet Union of foreign capital. This "long-term strategic offensive," which "contrasts with the essentially reactive and defensive strategy of "containment", accelerated the fall of the Soviet Union by encouraging it to overextend its economic base. The proposition that special operations by the CIA in Saudi Arabia affected the prices of Soviet oil was refuted by Marshall Goldman—one of the leading experts on the economy of the Soviet Union—in his latest book. He pointed out that the Saudis decreased their production of oil in 1985 (it reached a 16-year low), whereas the peak of oil production was reached in 1980. They increased the production of oil in 1986, reduced it in 1987 with a subsequent increase in 1988, but not to the levels of 1980 when production reached its highest level. The real increase happened in 1990, by which time the Cold War was almost over. In his book he asked why, if Saudi Arabia had such an effect on Soviet oil prices, did prices not fall in 1980 when the production of oil by Saudi Arabia reached its highest level—three times as much oil as in the mid-eighties—and why did the Saudis wait till 1990 to increase their production, five years after the CIA's supposed intervention? Why didn't the Soviet Union collapse in 1980 then? By the time Gorbachev ushered in the process that would lead to the dismantling of the Soviet administrative command economy through his programs of uskoreniye (speed-up of economic development) and perestroika (political and economic restructuring) announced in 1986, the Soviet economy suffered from both hidden inflation and pervasive supply shortages aggravated by an increasingly open black market that undermined the official economy. Additionally, the costs of superpower status—the military, space program, subsidies to client states—were out of proportion to the Soviet economy. The new wave of industrialization based upon information technology had left the Soviet Union desperate for Western technology and credits in order to counter its increasing backwardness. Reforms The Law on Cooperatives enacted in May 1988 was perhaps the most radical of the economic reforms during the early part of the Gorbachev era. For the first time since Vladimir Lenin's New Economic Policy, the law permitted private ownership of businesses in the services, manufacturing, and foreign-trade sectors. Under this provision, cooperative restaurants, shops, and manufacturers became part of the Soviet scene. Glasnost resulted in greater freedom of speech and the press becoming far less controlled. Thousands of political prisoners and many dissidents were also released. Soviet social science became free to explore and publish on many subjects that had previously been off limits, including conducting public opinion polls. The All−Union Center for Public Opinion Research (VCIOM)—the most prominent of several polling organizations that were started then— was opened. State archives became more accessible, and some social statistics that had been kept secret became open for research and publication on sensitive subjects such as income disparities, crime, suicide, abortion, and infant mortality. The first center for gender studies was opened within a newly formed Institute for the Socio−Economic Study of Human Population. In January 1987, Gorbachev called for democratization: the infusion of democratic elements such as multi-candidate elections into the Soviet political process. A 1987 conference convened by Soviet economist and Gorbachev adviser Leonid Abalkin, concluded: "Deep transformations in the management of the economy cannot be realized without corresponding changes in the political system." In June 1988, at the CPSU's Nineteenth Party Conference, Gorbachev launched radical reforms meant to reduce party control of the government apparatus. On 1 December 1988, the Supreme Soviet amended the Soviet constitution to allow for the establishment of a Congress of People's Deputies as the Soviet Union's new supreme legislative body. Elections to the new Congress of People's Deputies were held throughout the USSR in March and April 1989. Gorbachev, as General Secretary of the Communist Party, could be forced to resign at any moment if the communist elite became dissatisfied with him. To proceed with reforms opposed by the majority of the communist party, Gorbachev aimed to consolidate power in a new position, President of the Soviet Union, which was independent from the CPSU and the soviets (councils) and whose holder could be impeached only in case of direct violation of the law. On 15 March 1990, Gorbachev was elected as the first executive president. At the same time, Article 6 of the constitution was changed to deprive the CPSU of a monopoly on political power. Unintended consequences Gorbachev's efforts to streamline the Communist system offered promise, but ultimately proved uncontrollable and resulted in a cascade of events that eventually concluded with the dissolution of the Soviet Union. Initially intended as tools to bolster the Soviet economy, the policies of perestroika and glasnost soon led to unintended consequences. Relaxation under glasnost resulted in the Communist Party losing its absolute grip on the media. Before long, and much to the embarrassment of the authorities, the media began to expose severe social and economic problems the Soviet government had long denied and actively concealed. Problems receiving increased attention included poor housing, alcoholism, drug abuse, pollution, outdated Stalin-era factories, and petty to large-scale corruption, all of which the official media had ignored. Media reports also exposed crimes committed by Joseph Stalin and the Soviet regime, such as the gulags, his treaty with Adolf Hitler, and the Great Purges, which had been ignored by the official media. Moreover, the ongoing war in Afghanistan, and the mishandling of the 1986 Chernobyl disaster, further damaged the credibility of the Soviet government at a time when dissatisfaction was increasing. In all, the positive view of Soviet life long presented to the public by the official media was rapidly fading, and the negative aspects of life in the Soviet Union were brought into the spotlight. This undermined the faith of the public in the Soviet system and eroded the Communist Party's social power base, threatening the identity and integrity of the Soviet Union itself. Fraying amongst the members of the Warsaw Pact countries and instability of its western allies, first indicated by Lech Wałęsa's 1980 rise to leadership of the trade union Solidarity, accelerated, leaving the Soviet Union unable to depend upon its Eastern European satellite states for protection as a buffer zone. By 1989, following his doctrine of "new political thinking", Gorbachev had repudiated the Brezhnev Doctrine in favor of non-intervention in the internal affairs of its Warsaw Pact allies ("Sinatra Doctrine"). Gradually, each of the Warsaw Pact countries saw their communist governments fall to popular elections and, in the case of Romania, a violent uprising. By 1990, the governments of Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania, all of which had been imposed after World War II, were brought down as revolutions swept Eastern Europe. The Soviet Union also began experiencing upheaval as the political consequences of glasnost reverberated throughout the country. Despite efforts at containment, the upheaval in Eastern Europe inevitably spread to nationalities within the USSR. In elections to the regional assemblies of the Soviet Union's constituent republics, nationalists as well as radical reformers swept the board. As Gorbachev had weakened the system of internal political repression, the ability of the USSR's central Moscow government to impose its will on the USSR's constituent republics had been largely undermined. Massive peaceful protests in the Baltic republics such as the Baltic Way and the Singing Revolution drew international attention and bolstered independence movements in various other regions. The rise of nationalism under freedom of speech soon re-awakened simmering ethnic tensions in various Soviet republics, further discrediting the ideal of a unified Soviet people. One instance occurred in February 1988, when the government in Nagorno-Karabakh, a predominantly ethnic Armenian region in the Azerbaijan SSR, passed a resolution calling for unification with the Armenian SSR. Violence against local Azerbaijanis was reported on Soviet television, provoking massacres of Armenians in the Azerbaijani city of Sumgait. Emboldened by the liberalized atmosphere of glasnost, public dissatisfaction with economic conditions was much more overt than ever before in the Soviet period. Although perestroika was considered bold in the context of Soviet history, Gorbachev's attempts at economic reform were not radical enough to restart the country's chronically sluggish economy in the late 1980s. The reforms made some inroads in decentralization, but Gorbachev and his team left intact most of the fundamental elements of the Stalinist system, including price controls, inconvertibility of the ruble, exclusion of private property ownership, and the government monopoly over most means of production. The value of all consumer goods manufactured in 1990 in retail prices was about 459 billion rubles ($2.1 trillion). Nevertheless, the Soviet government had lost control over economic conditions. Government spending increased sharply as an increasing number of unprofitable enterprises required state support and consumer price subsidies to continue. Tax revenues declined as republic and local governments withheld tax revenues from the central government under the growing spirit of regional autonomy. The anti−alcohol campaign reduced tax revenues as well, which in 1982 accounted for about 12% of all state revenue. The elimination of central control over production decisions, especially in the consumer goods sector, led to the breakdown in traditional supplier−producer relationships without contributing to the formation of new ones. Thus, instead of streamlining the system, Gorbachev's decentralization caused new production bottlenecks. Dissolution of the USSR The dissolution of the Soviet Union' was a process of systematic disintegration, which occurred in the economy, social structure and political structure. It resulted in the abolition of the Soviet Federal Government ("the Union center") and independence of the USSR's republics on 26 December 1991. The process was caused by a weakening of the Soviet government, which led to disintegration and took place from about 19 January 1990 to 26 December 1991. The process was characterized by many of the republics of the Soviet Union declaring their independence and being recognized as sovereign nation-states. Andrei Grachev, the Deputy Head of the Intelligence Department of the Central Committee, summed up the denouement of the downfall quite cogently: "Gorbachev actually put the sort of final blow to the resistance of the Soviet Union by killing the fear of the people. It was still that this country was governed and kept together, as a structure, as a government structure, by the fear from Stalinist times." Summary The principal elements of the old Soviet political system were Communist Party dominance, the hierarchy of soviets, state socialism, and ethnic federalism. Gorbachev's programs of perestroika (restructuring) and glasnost (openness) produced radical unforeseen effects that brought that system down. As a means of reviving the Soviet state, Gorbachev repeatedly attempted to build a coalition of political leaders supportive of reform and created new arenas and bases of power. He implemented these measures because he wanted to resolve serious economic problems and political inertia that clearly threatened to put the Soviet Union into a state of long-term stagnation. But by using structural reforms to widen opportunities for leaders and popular movements in the union republics to gain influence, Gorbachev also made it possible for nationalist, orthodox communist, and populist forces to oppose his attempts to liberalize and revitalize Soviet communism. Although some of the new movements aspired to replace the Soviet system altogether with a liberal democratic one, others demanded independence for the national republics. Still others insisted on the restoration of the old Soviet ways. Ultimately, Gorbachev could not forge a compromise among these forces and the consequence was the dissolution of the Soviet Union. Post-Soviet restructuring To restructure the Soviet administrative command system and implement a transition to a market economy, Yeltsin's shock program was employed within days of the dissolution of the Soviet Union. The subsidies to money-losing farms and industries were cut, price controls abolished, and the ruble moved towards convertibility. New opportunities for Yeltsin's circle and other entrepreneurs to seize former state property were created, thus restructuring the old state-owned economy within a few months. After obtaining power, the vast majority of "idealistic" reformers gained huge possessions of state property using their positions in the government and became business oligarchs in a manner that appeared antithetical to an emerging democracy. Existing institutions were conspicuously abandoned prior to the establishment of new legal structures of the market economy such as those governing private property, overseeing financial markets, and enforcing taxation. Market economists believed that the dismantling of the administrative command system in Russia would raise GDP and living standards by allocating resources more efficiently. They also thought the collapse would create new production possibilities by eliminating central planning, substituting a decentralized market system, eliminating huge macroeconomic and structural distortions through liberalization, and providing incentives through privatization. Since the USSR's collapse, Russia faced many problems that free market proponents in 1992 did not expect. Among other things, 25% of the population lived below the poverty line, life expectancy had fallen, birthrates were low, and the GDP was halved. There was a sharp increase in economic inequality between 1988/1989 and 1993/1995, with the Gini ratio increasing by an average of 9 points for all former socialist countries. These problems led to a series of crises in the 1990s, which nearly led to the election of Yeltsin's Communist challenger, Gennady Zyuganov, in the 1996 presidential election. After the turn of the century, the economy of Russia has begun to improve greatly, due to major investments and business development and also due to high prices of natural resources. See also
for the position of General Secretary. Gromyko's removal as Foreign Minister was the most unexpected change given his decades of unflinching, faithful service compared to the unknown, inexperienced Shevardnadze. More predictably, the 80-year-old Nikolai Tikhonov, the Chairman of the Council of Ministers, was succeeded by Nikolai Ryzhkov, and Vasili Kuznetsov, the acting Chairman of the Presidium of the Supreme Soviet, was succeeded by Andrei Gromyko, the former Minister of Foreign Affairs. Further down the chain, up to 40% of the first secretaries of the oblasts (provinces) were replaced with younger, better educated, and more competent men. The defense establishment was also given a thorough shakeup with the commanders of all 16 military districts replaced along with all theaters of military operation, as well as the three Soviet fleets. Not since World War II had the Soviet military had such a rapid turnover of officers. Sixty-eight-year-old Marshal Nikolai Ogarkov was fully rehabilitated after having fallen from favor in 1983–84 due to his handling of the KAL 007 shootdown and his ideas about improving Soviet strategic and tactical doctrines were made into an official part of defense policy, although some of his other ambitions such as developing the military into a smaller, tighter force based on advanced technology were not considered feasible for the time being. Many, but not all, of the younger army officers appointed during 1985 were proteges of Ogarkov. Gorbachev got off to an excellent start during his first months in power. He projected an aura of youth and dynamism compared to his aged predecessors and made frequent walks in the streets of the major cities answering questions from ordinary citizens. He became the first leader that spoke with the Soviet people in person. When he made public speeches, he made clear that he was interested in constructive exchanges of ideas instead of merely reciting lengthy platitudes about the excellence of the Soviet system. He also spoke candidly about the slackness and run-down condition of Soviet society in recent years, blaming alcohol abuse, poor workplace discipline, and other factors for these situations. Alcohol was a particular nag of Gorbachev's, especially as he himself did not drink, and he made one of his major policy aims curbing the consumption of it. Foreign policy In terms of foreign policy, the most important one, relations with the United States, remained twitchy through 1985. In October, Gorbachev made his first visit to a non-communist country when he traveled to France and was warmly received. The fashion-conscious French were also captivated by his wife Raisa and political pundits widely believed that the comparatively young Soviet leader would have a PR advantage over President Reagan, who was 20 years his senior. Reagan and Gorbachev met for the first time in Geneva in November. The three weeks preceding the summit meeting were marked by an unprecedented Soviet media campaign against the Strategic Defense Initiative (SDI), taking advantage of opposition at home in the US to the program. When it finally took place, the two superpower leaders established a solid rapport that boded well for the future despite Reagan's refusal to compromise on abandonment of SDI. A joint communique by both parties stated that they were in agreement that nuclear war could not be won by either side and must never be allowed to happen. It was also agreed that Reagan and Gorbachev would carry out two more summit meetings in 1986–87. Jimmy Carter had decisively ended the policy of détente, by financially aiding the Mujahideen movement in neighboring Socialist Afghanistan, which served as a pretext for the Soviet intervention in Afghanistan six months later, with the aims of supporting the Afghan government, controlled by the People's Democratic Party of Afghanistan. Tensions between the superpowers increased during this time, when Carter placed trade embargoes on the Soviet Union and stated that the Soviet invasion of Afghanistan was "the most serious threat to the peace since the Second World War." Economy East-West tensions increased during the first term of US President Ronald Reagan (1981–85), reaching levels not seen since the Cuban Missile Crisis as Reagan increased US military spending to 7% of the GDP. To match the military buildup, the Soviet Union increased its own military spending to 27% of its GDP and froze production of civilian goods at 1980 levels, causing a sharp economic decline in the already failing Soviet economy. The US financed the training for the Mujahideen warlords such as Jalaluddin Haqqani, Gulbudin Hekmatyar and Burhanuddin Rabbani eventually culminated to the fall of the Soviet satellite the Democratic Republic of Afghanistan. While the CIA and MI6 and the People's Liberation Army of China financed the operation along with the Pakistan government against the Soviet Union, eventually the Soviet Union began looking for a withdrawal route and in 1988 the Geneva Accords were signed between Communist-Afghanistan and the Islamic Republic of Pakistan; under the terms Soviet troops were to withdraw. Once the withdrawal was complete the Pakistan ISI continued to support the Mujahideen against the Communist Government and by 1992, the government collapsed. US President Reagan also actively hindered the Soviet Union's ability to sell natural gas to Europe whilst simultaneously actively working to keep gas prices low, which kept the price of Soviet oil low and further starved the Soviet Union of foreign capital. This "long-term strategic offensive," which "contrasts with the essentially reactive and defensive strategy of "containment", accelerated the fall of the Soviet Union by encouraging it to overextend its economic base. The proposition that special operations by the CIA in Saudi Arabia affected the prices of Soviet oil was refuted by Marshall Goldman—one of the leading experts on the economy of the Soviet Union—in his latest book. He pointed out that the Saudis decreased their production of oil in 1985 (it reached a 16-year low), whereas the peak of oil production was reached in 1980. They increased the production of oil in 1986, reduced it in 1987 with a subsequent increase in 1988, but not to the levels of 1980 when production reached its highest level. The real increase happened in 1990, by which time the Cold War was almost over. In his book he asked why, if Saudi Arabia had such an effect on Soviet oil prices, did prices not fall in 1980 when the production of oil by Saudi Arabia reached its highest level—three times as much oil as in the mid-eighties—and why did the Saudis wait till 1990 to increase their production, five years after the CIA's supposed intervention? Why didn't the Soviet Union collapse in 1980 then? By the time Gorbachev ushered in the process that would lead to the dismantling of the Soviet administrative command economy through his programs of uskoreniye (speed-up of economic development) and perestroika (political and economic restructuring) announced in 1986, the Soviet economy suffered from both hidden inflation and pervasive supply shortages aggravated by an increasingly open black market that undermined the official economy. Additionally, the costs of superpower status—the military, space program, subsidies to client states—were out of proportion to the Soviet economy. The new wave of industrialization based upon information technology had left the Soviet Union desperate for Western technology and credits in order to counter its increasing backwardness. Reforms The Law on Cooperatives enacted in May 1988 was perhaps the most radical of the economic reforms during the early part of the Gorbachev era. For the first time since Vladimir Lenin's New Economic Policy, the law permitted private ownership of businesses in the services, manufacturing, and foreign-trade sectors. Under this provision, cooperative restaurants, shops, and manufacturers became part of the Soviet scene. Glasnost resulted in greater freedom of speech and the press becoming far less controlled. Thousands of political prisoners and many dissidents were also released. Soviet social science became free to explore and publish on many subjects that had previously been off limits, including conducting public opinion polls. The All−Union Center for Public Opinion Research (VCIOM)—the most prominent of several polling organizations that were started then— was opened. State archives became more accessible, and some social statistics that had been kept secret became open for research and publication on sensitive subjects such as income disparities, crime, suicide, abortion, and infant mortality. The first center for gender studies was opened within a newly formed Institute for the Socio−Economic Study of Human Population. In January 1987, Gorbachev called for democratization: the infusion of democratic elements such as multi-candidate elections into the Soviet political process. A 1987 conference convened by Soviet economist and Gorbachev adviser Leonid Abalkin, concluded: "Deep transformations in the management of the economy cannot be realized without corresponding changes in the political system." In June 1988, at the CPSU's Nineteenth Party Conference, Gorbachev launched radical reforms meant to reduce party control of the government apparatus. On 1 December 1988, the Supreme Soviet amended the Soviet constitution to allow for the establishment of a Congress of People's Deputies as the Soviet Union's new supreme legislative body. Elections to the new Congress of People's Deputies were held throughout the USSR in March and
a short while before Corsica was ceded by Genoa to France in 1767, the local dialect (called isulanu or maddaleninu) was brought by fishermen and shepherds from Bonifacio over a long period of immigration in the 17th and 18th centuries. Though influenced by Gallurese, it has maintained the original characteristics of Southern Corsican. In the dialect of maddalenino, as it is known in Italian, there are also numerous words of Genoese and Ponzese origin. Although Gallurese and Sassarese both belong to Italo-Dalmatian, which is a group typologically different from Sardinian, it has long been a subject of debate whether the two should be included as dialects either of Corsican or of Sardinian or, in light of their historical development, even considered languages of their own. It has been argued that all these varieties should be placed in a single category, Southern Romance, but such classification has not garnered universal support among linguists. On 14 October 1997, Article 2 Item 4 of Law Number 26 of the Autonomous Region of Sardinia granted "the Sassarese and Gallurese dialects" («al dialetto sassarese e a quello gallurese») equal legal status with the other languages indigenous to Sardinia. Thus, even though they would technically not be covered by the national law pertaining to the historical linguistic minorities, among which is Sardinian, Sassarese and Gallurese are nonetheless recognized by the Sardinian government on a regional level. Examples of the main Corsican varieties compared with standard Italian and Elba's Tuscan dialect Number of speakers The situation of Corsican with regard to French as the country's national language is analogous to that of many other French regions and provinces, which have or used to have a traditional language of their own, even though the islanders' switch from their local idiom to regional French has happened relatively later and the presence of Corsican, albeit declining, is still strongly felt among the population. In 1980, about 70 percent of the island's population "had some command of the Corsican language." In 1990, out of a total population of about 254,000, the percentage had declined to 50 percent, with 10 percent of the island's residents using it as a first language. The language appeared to be in serious decline when the French government reversed its unsupportive stand and initiated some strong measures to save it. The January 2007 estimated population of Corsica was 281,000, whereas the figure for the March 1999 census, when most of the studies—though not the linguistic survey work referenced in this article—were performed, was about 261,000. Only a fraction of the population at either time spoke Corsican with any fluency. According to an official survey run on behalf of the Collectivité territoriale de Corse which took place in April 2013, in Corsica, the Corsican language had a number of speakers between 86,800 and 130,200, out of a total population amounting to 309,693 inhabitants. 28% of the overall population was able to speak Corsican well, whilst an additional 14% had a capacity to speak it "quite well." The percentage of those who had a solid oral understanding of the language varies between a minimum of 25 percent in the 25–34 age group and the maximum of 65 percent in the over-65 age group: almost a quarter of the former age group reported that they were not able to understand Corsican, while only a small minority of the older people did not understand it. While 32 percent of the population of Northern Corsica was reported to speak Corsican quite well, this percentage dropped to 22 percent for Southern Corsica. Moreover, 10 percent of the population of Corsica spoke only French, while 62 percent code-switched between French and at least some Corsican. 8 percent of the Corsicans knew how to write correctly in Corsican, while about 60 percent of the population did not know how to write in Corsican. While 90 percent of the population was in favor of a Corsican-French bilingualism, 3 percent would have liked to have only Corsican as the official language in the island, and 7 percent would have preferred French to have this role. UNESCO classifies Corsican as a "definitely endangered language." The Corsican language is a key vehicle for Corsican culture, which is notably rich in proverbs and in polyphonic song. Governmental support When the French Assembly passed the Deixonne Law in 1951, which made it possible for regional languages to be taught at school, Alsatian, Flemish and Corsican were not included on the ground of being classified as dialectes allogènes of German, Dutch and Italian respectively, i.e. dialects of foreign languages and not languages in themselves. Only in 1974 were they too politically recognized as regional languages for their teaching on a voluntary basis. The 1991 "Joxe Statute", in setting up the Collectivité Territoriale de Corse, also provided for the Corsican Assembly, and charged it with developing a plan for the optional teaching of Corsican. The University of Corsica Pasquale Paoli at Corte, Haute-Corse took a central role in the planning. At the primary school level Corsican is taught up to a fixed number of hours per week (three in the year 2000) and is a voluntary subject at the secondary school level, but is required at the University of Corsica. It is available through adult education. It can be spoken in court or in the conduct of other government business if the officials concerned speak it. The Cultural Council of the Corsican Assembly advocates for its use, for example, on public signs. Literature According to the anthropologist Dumenica Verdoni, writing new literature in modern Corsican, known as the Riacquistu, is an integral part of affirming Corsican identity. Some individuals have returned from careers in continental France to write in Corsican, including Dumenicu Togniotti, director of the Teatru Paisanu, which produced polyphonic musicals, 1973–1982, followed in 1980 by Michel Raffaelli's Teatru di a Testa Mora, and Saveriu Valentini's Teatru Cupabbia in 1984. Modern prose writers include Alanu di Meglio, Ghjacumu Fusina, Lucia Santucci, and Marcu Biancarelli. There were writers working in Corsican in the 1700s and 1800s. Ferdinand Gregorovius, a 19th-century traveller and enthusiast of Corsican culture, reported that the preferred form of the literary tradition of his time was the vocero, a type of polyphonic ballad originating from funeral obsequies. These laments were similar in form to the chorales of Greek drama except that the leader could improvise. Some performers were noted at this, such as the 1700s Mariola della Piazzole and Clorinda Franseschi. However, the trail of written popular literature of known date in Corsican currently goes no further back than the 17th century. An undated corpus of proverbs from communes may well precede it (see under External links below). Corsican has also left a trail of legal documents ending in the late 12th century. At that time the monasteries held considerable land on Corsica and many of the churchmen were notaries. Between 1200 and 1425 the monastery of Gorgona, which belonged to the Order of Saint Benedict for much of that time and was in the territory of Pisa, acquired about 40 legal papers of various sorts related to Corsica. As the church was replacing Pisan prelates with Corsican ones there, the legal language shows a transition from entirely Latin through partially Latin and partially Corsican to entirely Corsican. The first known surviving document containing some Corsican is a bill of sale from Patrimonio dated to 1220. These documents were moved to Pisa before the monastery closed its doors and were published there. Research into earlier evidence of Corsican is ongoing. Alphabet and spelling Corsican is written in the standard Latin script, using 21 of the letters for native words. The letters j, k, w, x, and y are found only in foreign names and French vocabulary. The digraphs and trigraphs chj, ghj, sc and sg are also defined as "letters" of the alphabet in its modern scholarly form (compare the presence of ch or ll in the old Spanish alphabet) and appear respectively after c, g and s. The primary diacritic used is the grave accent, indicating word stress when it is not penultimate. In scholarly contexts, disyllables may be distinguished from diphthongs by use of the diaeresis on the former vowel (as in Italian and distinct from French and English). In older writing, the acute accent is sometimes found on stressed , the circumflex on stressed , indicating respectively () and () phonemes. Corsican has been regarded as a dialect of Italian historically, similar to the Romance lects developed on the Italian peninsula, and in writing, it also resembles Italian (with the generalised substitution of -u for final -o and the articles u and a for il/lo and la respectively; however, both the dialect of Cap Corse and Gallurese retain the original articles lu and la). On the other hand, the phonemes of the modern Corsican dialects have undergone complex and sometimes irregular phenomena depending on phonological context, so the pronunciation of the language for foreigners familiar with other Romance languages is not straightforward. Phonology Vowels As in Italian, the grapheme appears in some digraphs and trigraphs in which it does not represent the phonemic vowel. All vowels are pronounced except in a few well-defined instances. is not pronounced between and : sciarpa ; or initially in some words: istu . Vowels may be nasalized before (which is assimilated to before or ) and the palatal nasal consonant represented by . The nasal vowels are represented by the vowel plus , or . The combination is a digraph or trigraph indicating the nasalized vowel. The consonant is pronounced in weakened form. The same combination of letters might not be the digraph or trigraph but might be just the non-nasal vowel followed by the consonant at full weight. The speaker must know the difference. Example of nasal: is pronounced and not . The Northern and central dialects in the vicinity of the Taravo river adopt the Italian seven-vowel system, whereas all the Southern ones around the so-called "archaic zone" with its centre being the town of Sartène (including the Gallurese dialect spoken in Northern Sardinia) resort to a five-vowel system without length differentiation, like Sardinian. The vowel inventory, or collection of phonemic
an official setting. "Tuscanising" their tongue, or as the Corsican elites would have once said, parlà in crusca ("speaking in crusca", from the name of the Academy dedicated to the standardisation of the Italian language), allowed for a practice not of code-switching, but rather of code-mixing which is quite typical of the Mainland Italian dialects. Italian was perceived as "other" from Corsican, but not more so than the two main isoglosses of Northern and Southern Corsican were between each other by their respective native speakers. When Pasquale Paoli found himself exiled in London, he replied to Samuel Johnson's query on the peculiar existence of a "rustic language" very different from Italian that such a language only existed in Sardinia; in fact, the existence of Corsican as the island's native vernacular did not take anything away from Paoli's claims that Corsica's official language was Italian. Today's Corsican is the result of these historical vicissitudes, which have morphed the language to an idiom that bears a strong resemblance to the medieval Tuscan once spoken at the time of Dante and Boccaccio, and still existing in peripheral Tuscany (Lucca, Garfagnana, Elba, Capraia). The correspondence of modern Corsican to ancient Tuscan concerns any aspect of the language, ranging from the phonetics, morphology, lexicon to the syntax. One of the characteristics of standard Italian is the retention of the -re infinitive ending, as in Latin mittere "send"; such infinitival ending is lost in Tuscan as well as Corsican, resulting in the outcome mette / metta, "to put". Whereas the relative pronoun in Italian for "who" is chi and "what" is che/(che) cosa, it is an uninflected chì in Corsican. Perhaps the biggest difference between standard Italian and Corsican is that the latter uses the u termination, whereas standard Italian has switched to the o ending. For example, the Italian demonstrative pronouns questo "this" and quello "that" become in Corsican questu or quistu and quellu or quiddu: this feature was typical of the early Italian texts during the Middle Ages. Even after the acquisition of Corsica by Louis XV, Italian continued to be the island's language of education, literature, religion and local affairs. The affluent youth, such as the future Emperor of the French, still went to Italy to pursue higher studies (it has been estimated that Corsican presence in Pisa amounted to a fourth of the University's total student body in 1830), and local civil registers would not stop being written in Italian until 1855; it was on May 9, 1859 that Italian was replaced by French as the island's official language, even though the latter would start to take root among the islanders from 1882 onwards, through the Jules Ferry's laws aimed at spreading literacy across the French provinces. Even so, a specifically homegrown Corsican rather than Italian literature in Corsica would not be born but belatedly and, in its earliest phase, would not carry autonomous cultural instances; Corsican writers, such as Salvatore Viale, even prided themselves on their affiliation to the broader Italian sphere, considering Corsican «one of the least impure dialects of Italy». It was the Italian Fascist aggressive claims to the island, followed by their invasion, that provoked a popular backlash estranging the native islanders and, if anything, only accelerated their shifting to the French national language even further. By the Liberation, any previously existing link between the two linguistic varieties and with Italy altogether had been severed; any promotion of Corsican, which had been politicized by the local collaborators with the regime, would be met with popular criticism and even suspicion of potentially harboring irredentist sentiments. From then on, Corsican would grow autonomously from Italian to become later in the 1970s a centerpiece of the Riacquistu ("reacquisition") movement for the rediscovery of Corsican culture. Nationalist calls for Corsican to be put on the same footing as French led the French National Assembly to extend the 1951 Deixonne Law, which initially recognized only a few languages (Breton, Basque, Catalan and Occitan), to including Corsican as well, among others, not as a dialect of Italian, but as one of France's full-fledged regional languages in 1974 (see governmental support). Origins The common relationship between Corsica and central Italy can be traced from as far back as the Etruscans, who asserted their presence on the island in as early as 500 BC. In 40 AD, the natives of Corsica did not reportedly speak Latin. The Roman exile, Seneca the Younger, reports that both coast and interior were occupied by natives whose language he was not able to understand. More specifically, Seneca claimed that the island's population was the result of the stratification of different ethnic groups, such as the Greeks, the Ligures (see the Ligurian hypothesis) and the Iberians, whose language had long since stopped being recognizable among the population due to the intermixing of the other two groups. The occupation of the island by the Vandals around the year 469 marked the end of authoritative influence by Latin speakers (see Medieval Corsica). If the natives of that time spoke Latin, they must have acquired it during the late empire. Modern Corsican has been influenced by the languages of the major powers taking an interest in Corsican affairs; earlier by those of the medieval Italian powers, such as the Papal States (828–1077), the Republic of Pisa (1077–1282) and the Republic of Genoa (1282–1768), and finally by France which, since 1859, has promulgated the official Parisian French. The term "gallicised Corsican" refers to the evolution of Corsican starting from about the year 1950, whereas "distanciated Corsican" refers to an idealized variety of Corsican following linguistic purism, by means of removing any French-derived elements. Dialects Corsica The two most widely spoken forms of the Corsican language are the groups spoken in the Bastia and Corte area (generally throughout the northern half of the island, known as Haute-Corse, Cismonte or Corsica suprana), and the groups spoken around Sartène and Porto-Vecchio (generally throughout the southern half of the island, known as Corse-du-Sud, Pumonti or ). The dialect of Ajaccio has been described as in transition. The dialects spoken at Calvi and Bonifacio are closer to the Genoese dialect, also known as Ligurian. This division along the Girolata-Porto Vecchio line was due to the massive immigration from Tuscany which took place in Corsica during the lower Middle Ages: as a result, the northern Corsican dialects became very close to a central Italian dialect like Tuscan, while the southern Corsican varieties could keep the original characteristics of the language which make it much more similar to Sicilian and, only to some extent, Sardinian. Northern Corsican The Northern Corsican macro variety (Supranacciu, Supranu, Cismuntincu or Cismontano) is the most widespread on the island and standardised as well, and is spoken in North-West Corsica around the districts of Bastia and Corte. The dialects of Bastia and Cap Corse belong to the Western Tuscan dialects; they being, with the exception of Florentine, the closest to standard Italian. All the dialects presenting, in addition to what has already been stated, the conditional formed in (e.g. "she would love") are generally considered Cismontani dialects, situated north of a line uniting the villages of Piana, Vico, Vizzavona, Ghisoni and Ghisonaccia, and also covering the subgroups from the Cap Corse (which, unlike the rest of the island and similarly to Italian, uses lu, li, la, le as definite articles), Bastia (besides i > e and a > e, u > o: , , , ; a > o: , , ), Balagna, Niolo and Corte (which retain the general Corsican traits: , , , , , , , , , , , , , , ). Transitional area Across the Northern and Southern borders of the line separating the Northern dialects from the Southern ones, there is a transitional area picking up linguistic phenomena associated with either of the two groups, with some local peculiarities. Along the Northern line are the dialects around Piana and Calcatoggio, from Cinarca with Vizzavona (which form the conditional tense like in the South), and Fiumorbo through Ghisonaccia and Ghisoni, which have the retroflex sound (written -dd-) for historical ; along the Southern line, the dialects of Ajaccio (retroflex -dd-, realized as -ghj-, feminine plurals ending in i, some Northern words like cane and accattà instead of ghjacaru and cumprà, as well as ellu/ella and not eddu/edda; minor variations: sabbatu > sabbitu, u li dà > ghi lu dà; final syllables often stressed and truncated: marinari > marinà, > panattè, castellu > castè, cuchjari > cuchjà), the Gravona area, Bastelica (which would be classified as Southern, but is also noted for its typical rhotacism: Basterga) and Solenzara, which did not preserve the Latin short vowels: seccu, peru, rossu, croci, pozzu). Southern Corsican The Southern Corsican macro variety (Suttanacciu, Suttanu, Pumontincu or Oltramontano) is the most archaic and conservative group, spoken in the districts of Sartène and Porto-Vecchio. Unlike the Northern varieties and
Germany in Frankfurt stating 'The CD32 was a year late for Commodore. In other words, here, too, it might have been better to focus on the core business than jump on a console and hope to sell 300,000 or more units in a short period of time to avoid bankruptcy. In 1992, all UK servicing and warranty repairs were outsourced to Wang Laboratories, which was replaced by ICL after failing to meet repair demand during the Christmas rush in 1992. By 1994, only the operations in Germany and the United Kingdom were still profitable. Commodore declared bankruptcy on April 29, 1994, and ceased to exist, causing the board of directors to "authorize the transfer of its assets to trustees for the benefit of its creditors", according to an official statement. The company's computer systems, especially the C64 and Amiga series, retains a cult following decades after its demise. Post-Commodore International Ltd. Following its liquidation, Commodore's former assets went their separate ways, with none of the descendant companies repeating Commodore's early success. Both Commodore and Amiga product lines were produced in the 21st century, but separately with Amiga, Inc. being its own company and Commodore computers briefly being produced by Commodore USA, an unrelated Florida-based company that licensed the brand name. Other companies develop operating systems and manufacture computers for both Commodore and Amiga brands as well as software. Commodore UK and Commodore BV (Netherlands) were the subsidiaries that survived the bankruptcy but failed to placed a bid to buy out the rest of the operation, or at least the former parent company. Due to press exposure at the time Commodore UK was considered the front runner in the bid. Commodore UK and Commodore BV (Netherlands) stayed in business by selling old inventory and making computer speakers and some other types of computer peripherals. Commodore BV (Netherlands) dissolved in early 1995, leaving Commodore UK left to make a bid. However, Commodore UK withdrew its bid at the start of the auction process after several larger companies, including Gateway Computers and Dell Inc., became interested, primarily for Commodore's 47 patents relating to the Amiga. The only companies who entered bids were Dell and Escom. the successful bidder was German PC conglomerate Escom, and Commodore UK went into liquidation on August 30, 1995. In 1995 Escom paid US$14 million for the assets of Commodore International. It separated the Commodore and Amiga operations into separate divisions and quickly started using the Commodore brand name on a line of PCs sold in Europe. However, it soon started losing money due to over-expansion, went bankrupt on July 15, 1996, and was liquidated. In September 1997, the Commodore brand name was acquired by Dutch computer maker Tulip Computers. In July 2004, Tulip announced a new series of products using the Commodore name: fPET, a flash memory-based USB Flash drive; mPET, a flash-based MP3 Player and digital recorder; eVIC, a 20 GB music player. Also, it licensed the Commodore trademark and Chicken Lips logo to the producers of the C64 DTV, a single-chip implementation of the Commodore 64 computer with 30 built-in games. In late 2004, Tulip sold the Commodore trademarks to Yeahronimo Media Ventures for €22 million. The sale was completed in March 2005 after months of negotiations. Yeahronimo Media Ventures soon renamed itself to Commodore International Corporation and started an operation intended to relaunch the Commodore brand. The company launched its Gravel line of products: personal multimedia players equipped with Wi-Fi, with the hope the Commodore brand would help them take off. The Gravel was never a success and was discontinued. On June 24, 2009, CIC renamed itself to Reunite Investments. CIC's founder, Ben van Wijhe, bought a Hong Kong-based company called Asiarim. The brand is now owned by C= Holdings (formerly Commodore International B.V.): Reunite became the sole owner of it in 2010, after buying the remaining shares from the bankrupt Nedfield, then sold it to Commodore Licensing BV, a subsidiary of Asiarim, later in 2010. It was sold again on November 7, 2011: this transaction became the basis of a legal dispute between Asiarim (which, even after that date, made commercial use of the Commodore trademark, among others by advertising for sale Commodore-branded computers, and dealing licensing agreements for the trademarks) and the new owners, that was resolved by the United States District Court for the Southern District of New York on December 16, 2013 in favour of the new owners. The Commodore Semiconductor Group (formerly MOS Technology, Inc.) was bought by its former management and in 1995, resumed operations under the name GMT Microelectronics, utilizing a troubled facility in Norristown, Pennsylvania that Commodore had closed in 1992. By 1999 it had $21 million in revenues and 183 employees. However, in 2001 the United States Environmental Protection Agency shut the plant down. GMT ceased operations and was liquidated. Ownership of the remaining assets of Commodore International, including the copyrights and patents, and the Amiga trademarks, passed from Escom to U.S. PC clone maker Gateway 2000 in 1997, who retained the patents and sold the copyrights and trademarks, together with a license to use the patents, to Amiga, Inc., a Washington company founded, among others, by former Gateway subcontractors Bill McEwen and Fleecy Moss in 2000. On March 15, 2004, Amiga, Inc. announced that on April 23, 2003 it had transferred its rights over past and future versions of the Amiga OS (but not yet over other intellectual property) to Itec, LLC, later acquired by KMOS, Inc., a Delaware company. Shortly afterwards, on the basis of some loans and security agreements between Amiga, Inc. and Itec, LLC, the remaining intellectual property assets were also transferred from Amiga, Inc. to KMOS, Inc. On March 16, 2005, KMOS, Inc. announced that it had completed all registrations with the State of Delaware to change its corporate name to Amiga, Inc. The Commodore/Amiga copyrights were later sold to Cloanto. AmigaOS (as well as spin-offs MorphOS and AROS) is still maintained and updated. Several companies produce related hardware and software today. Commodore's former US headquarters in West Chester, Pennsylvania, is currently the headquarters to QVC. In February 2017 an exhibition room for about 200 Commodore products was opened in Braunschweig, commemorating the European production site of Commodore which had up to 2000 employees.

followed by filing lawsuits against four former engineers for theft of trade secrets in late July. This was intended, in effect, to bar Tramiel from releasing his new computer. One of Tramiel's first acts after forming Atari Corp. was to fire most of Atari's remaining staff, and to cancel almost all ongoing projects, in order to review their continued viability. In late July/early August, Tramiel representatives discovered the original Amiga contract from the previous fall. Seeing a chance to gain some leverage, Tramiel immediately used the contract to counter-sue Commodore through its new subsidiary, Amiga, on August 13. The Amiga crew, still suffering serious financial problems, had sought more monetary support from investors that entire spring. At around the same time that Tramiel was in negotiations with Atari, Amiga entered into discussions with Commodore. The discussions ultimately led to Commodore's intentions to purchase Amiga outright, which would (from Commodore's viewpoint) cancel any outstanding contracts including Atari Inc.'s. This "interpretation" is what Tramiel used to counter-sue, and sought damages and an injunction to bar Amiga (and effectively Commodore) from producing any resembling technology. This was an attempt to render Commodore's new acquisition (and the source for its next generation of computers) useless. The resulting court case lasted for several years, with both companies releasing their respective products. In the end, the Amiga computer outlasted the Atari. Throughout the life of the ST and Amiga platforms, a ferocious Atari-Commodore rivalry raged. While this rivalry was in many ways a holdover from the days when the Commodore 64 had first challenged the Atari 800 (among others) in a series of scathing television commercials, the events leading to the launch of the ST and Amiga only served to further alienate fans of each computer, who fought vitriolic holy wars on the question of which platform was superior. This was reflected in sales numbers for the two platforms until the release of the Amiga 500 in 1987, which led the Amiga sales to exceed the ST by about 1.5 to 1, despite reaching the market later. However, the battle was in vain, as neither platform captured a significant share of the world computer market and only the Apple Macintosh would survive the industry-wide shift to Microsoft Windows running on PC clones. Demise Adam Osborne stated in April 1981 that "the microcomputer industry abounds with horror stories describing the way Commodore treats its dealers and its customers." Many in the industry believed rumors in late 1983 that Commodore would discontinue the 64 despite its great success because they disliked the company's business practices, including poor treatment of dealers and introducing new computers incompatible with existing ones. One dealer said "It's too unsettling to be one of their dealers and not know where you stand with them." After Tramiel's departure, another journalist wrote that he "had never been able to establish very good relations with computer dealers ... computer retailers have accused Commodore of treating them as harshly as if they were suppliers or competitors, and as a result, many have become disenchanted with Commodore and dropped the product line". However, upon the 1987 introduction of the Amiga 2000, Commodore retreated from its earlier strategy of selling its computers to discount outlets and toy stores, and now favored authorized dealers. Software developers also disliked the company, with one stating that "Dealing with Commodore was like dealing with Attila the Hun." At the 1987 Comdex, an informal InfoWorld survey found that none of the developers present planned to write for Commodore platforms. Although Comdex was oriented toward business computing, not Commodore's traditional consumer market, such a response did not bode well for Commodore's efforts to establish the Amiga as a business platform. Commodore faced the problem, when marketing the Amiga, of still being seen as the company that made cheap computers like the 64 and VIC. By the late 1980s, the personal computer market had become dominated by the IBM PC and Apple Macintosh platforms and Commodore's marketing efforts for the Amiga were less successful in breaking the new computer into this now-established market than its promotions for the 8-bit line had been in making Commodore the home computer leader. The company put effort into developing and promoting consumer products that would not be in demand for years, such as an Amiga 500-based HTPC called CDTV. As early as 1986, the mainstream press was predicting Commodore's demise, and in 1990 Computer Gaming World wrote of its "abysmal record of customer and technical support in the past". Nevertheless, as profits and the stock price began to slide, The Philadelphia Inquirer's Top 100 Businesses annual continued to list several Commodore executives among the highest-paid in the region and the paper documented the company's questionable hiring practices and large bonuses paid to executives amid shareholder discontent. Commodore failed to update the Amiga to keep pace as the PC platform advanced. CBM continued selling the Amiga 2000 with 7.14 MHz 68000 CPUs, even though the Amiga 3000 with its 25 MHz 68030 was on the market. Apple by this time was using the 68040 and had relegated the 68000 to its lowest end model, the black and white Macintosh Classic. The 68000 was used in the Sega Genesis, one of the leading game consoles of the era, PCs fitted with high-color VGA graphics cards and SoundBlaster (or compatible) sound cards had finally caught up with the Amiga's performance and Commodore began to fade from the consumer market. Although the Amiga was originally conceived as a gaming machine, Commodore had always emphasized the Amiga's potential for professional applications. But the Amiga's high-performance sound and graphics were irrelevant for most of the day's MS-DOS-based routine business word-processing and data-processing requirements, and the machine could not successfully compete with PCs in a business market that was rapidly undergoing commoditization. Commodore introduced a range of PC compatible systems designed by its German division, and while the Commodore name was better known in the US than some of its competition, the systems' price and specs were only average. In 1992, the A600 replaced the A500. It removed the numeric keypad, Zorro expansion slot, and other functionality, but added IDE, PCMCIA and a theoretically cost-reduced design. Designed as the Amiga 300, a nonexpandable model to sell for less than the Amiga 500, the 600 was forced to become a replacement for the 500 due to the unexpected higher cost of manufacture. Productivity developers increasingly moved to PC and Macintosh, while the console wars took over the gaming market. David Pleasance, managing director of Commodore UK, described the A600 as a 'complete and utter screw-up'. In 1992, Commodore released the Amiga 1200 and Amiga 4000 computers, which featured an improved graphics chipset, the AGA. The advent of PC games using 3D graphics such as Doom and Wolfenstein 3D spelled the end of Amiga as a gaming platform, due to mismanagement. In 1993, the 'make or break' system, according to Pleasance, was a 32-bit CD-ROM-based game console called the Amiga CD32, but it was not sufficiently profitable to put Commodore back in the black. This was not a universal opinion at Commodore with hardware expert Rainer Benda who worked for Commodore Germany in Frankfurt stating 'The CD32 was a year late for Commodore. In other words, here, too, it might have been better to focus on the core business than jump on a console and hope to sell 300,000 or more units in a short period of time to avoid bankruptcy. In 1992, all UK servicing and warranty repairs were outsourced to Wang Laboratories, which was replaced by ICL after failing to meet repair demand during the Christmas rush in 1992. By 1994, only the operations in Germany and the United Kingdom were still profitable. Commodore declared bankruptcy on April 29, 1994, and ceased to exist, causing the board of directors to "authorize the transfer of its assets to trustees for the benefit of its creditors", according to an official statement. The company's computer systems, especially the C64 and Amiga series, retains a cult following decades after its demise. Post-Commodore International Ltd. Following its liquidation, Commodore's former assets went their separate ways, with none of the descendant companies repeating Commodore's early success. Both Commodore and Amiga product lines were produced in the 21st century, but separately with Amiga, Inc. being its own company and Commodore computers briefly being produced by Commodore USA, an unrelated Florida-based company that licensed the brand name. Other companies develop operating systems and manufacture computers for both Commodore and Amiga brands as well as software. Commodore UK and Commodore BV (Netherlands) were the subsidiaries that survived the bankruptcy but failed to placed a bid to buy out the rest of the operation, or at least the former parent company. Due to press exposure at the time Commodore UK was considered the front runner in the bid. Commodore UK and Commodore BV (Netherlands) stayed in business by selling old inventory and making computer speakers and some other types of computer peripherals. Commodore BV (Netherlands) dissolved in early 1995, leaving Commodore UK left to make a bid. However, Commodore UK withdrew its bid at the start of the auction process after several larger companies, including Gateway Computers and Dell Inc., became interested, primarily for Commodore's 47 patents relating to the Amiga. The only companies who entered bids were Dell and Escom. the successful bidder was German PC conglomerate Escom, and Commodore UK went into liquidation on August 30, 1995. In 1995 Escom paid US$14 million for the assets of Commodore International. It separated the Commodore and Amiga operations into separate divisions and quickly started using the Commodore brand name on a line of PCs sold in Europe. However, it soon started losing money due to over-expansion, went bankrupt on July 15, 1996, and was liquidated. In September 1997, the Commodore brand name was acquired by Dutch computer maker Tulip Computers. In July 2004, Tulip announced a new series of products using the Commodore name: fPET, a flash memory-based USB Flash drive; mPET, a flash-based MP3 Player and digital recorder; eVIC, a 20 GB music player. Also, it licensed the Commodore trademark and Chicken Lips logo to the producers of the C64 DTV, a single-chip implementation of the Commodore 64 computer with 30 built-in games. In late 2004, Tulip sold the Commodore trademarks to Yeahronimo Media Ventures for €22 million. The sale was completed in March 2005 after months of negotiations. Yeahronimo Media Ventures soon renamed itself to Commodore International Corporation and started an operation intended to relaunch the Commodore brand. The company launched its Gravel line of products: personal multimedia players equipped with Wi-Fi, with the hope the Commodore brand would help them take off. The Gravel was never a success and was discontinued. On June 24, 2009, CIC renamed itself to Reunite Investments. CIC's founder, Ben van Wijhe, bought a Hong Kong-based company called Asiarim.

for an equivalent rank. In the Royal Navy, the position was introduced in the 17th Century to combat the cost of appointing more admirals—a costly business with a fleet as large as the Royal Navy's at that time. The rank of commodore was at first a position created as a temporary title to be bestowed upon captains who commanded squadrons of more than one vessel. In many navies, the rank of commodore was merely viewed as a senior captain position, whereas other naval services bestowed upon the rank of commodore the prestige of flag officer status. United States In 1899, the substantive rank of commodore was discontinued in the United States Navy, but revived during World War II in both the U.S. Navy and U.S. Coast Guard. It was discontinued as a rank in these services during the postwar period, but as an appointment, the title "commodore" was then used to identify senior U.S. Navy captains who commanded squadrons of more than one vessel or functional air wings or air groups that were not part of a carrier air wing or carrier air group. Concurrently, until the early 1980s, U.S. Navy and U.S. Coast Guard captains selected for promotion to the rank of rear admiral (lower half), would wear the same insignia as rear admiral (upper half), i.e., two silver stars for collar insignia or sleeve braid of one wide and one narrow gold stripe, even though they were actually only equivalent to one-star officers and paid at the one-star rate. To correct this inequity, the rank of commodore as a single star flag officer was reinstated by both services in the early 1980s. This immediately caused confusion with those senior U.S. Navy captains commanding destroyer squadrons, submarine squadrons, functional air wings and air groups, and so on, who held the temporary "title" of commodore while in their major command billet. As a result of this confusion, the services soon renamed the new one-star rank as commodore admiral (CADM) within the first six months following the rank's reintroduction. However, this was considered an awkward title and the one-star flag rank was renamed a few months later to its current title of rear admiral (lower half), later abbreviated by the U.S. Navy and U.S. Coast Guard as RDML. The "title" of commodore continues to be used in the U.S. Navy and Coast Guard for those senior captains in command of organizations consisting of groups of ships or submarines organized into squadrons; air wings or air groups of multiple aviation squadrons other than carrier air wings (the latter whose commanders still use the title "CAG"); explosive ordnance disposal (EOD), mine warfare and special warfare (SEAL) groups; Mobile Inshore Underwater Warfare (MIUW) groups; and construction (SeaBee) regiments. Although not flag officers, modern day commodores in the U.S. Navy rate a blue and white command pennant, also known as a broad pennant, that is normally flown at their headquarters facilities ashore or from ships that they are embarked aboard when they are the senior officer present afloat (SOPA). Argentina In the Argentine Navy, the position of commodore was created in the late 1990s, and is usually, but not always, issued to senior captains holding rear-admirals' positions. It is not a rank but a distinction and, as such, can be issued by the chief of staff without congressional approval. Its equivalents are colonel-major in the Army and commodore-major in the Air Force. It is usually—but incorrectly—referred to as "navy commodore", to avoid confusion with the "air force commodore", which is equivalent to the navy's captain and army's colonel. The sleeve lace is identical to that of the Royal Navy, and wears one star on the epaulette. Naval rank The following articles deal with the rank of commodore (or its equivalent) as it is employed OF-6 one-star flag officer rank in various countries. Air force ranks Commodore, in Spanish comodoro, is a rank in the Argentine Air Force. This rank is the equivalent of a colonel in the Argentine Army, and a colonel or group captain in other air forces of the world. The Argentine rank below commodore is the rank of vice-commodore (Spanish vicecomodoro) equivalent to a lieutenant-colonel in the Argentine Army, and a lieutenant-colonel or wing commander in other air forces. Commodore is a rank in the Royal Netherlands Air Force. It is a one-star rank and has essentially the same rank
any officer assigned to command more than one ship, even temporarily, much as "captain" is the traditional title for the commanding officer of a single ship even if the officer's official title in the service is a lower rank. As an official rank, a commodore typically commands a flotilla or squadron of ships as part of a larger task force or naval fleet commanded by an admiral. A commodore's ship is typically designated by the flying of a broad pennant, as compared to an admiral's flag. "Commodore" is typically regarded as a one-star rank with a NATO code of OF-6, known in the U.S. as "rear admiral (lower half)", but whether it is regarded as a flag rank varies among countries. It is sometimes abbreviated as "Cdre" in British Royal Navy, "CDRE" in the US Navy, "Cmdre" in the Royal Canadian Navy, "COMO" in the Spanish Navy and in some navies speaking the Spanish language, or "CMDE" as used in the Indian Navy and in navies of several other countries. Etymology The rank of commodore derives from the French commandeur, which was one of the highest ranks in the orders of knighthood, and in military orders the title of the knight in charge of a commande (a local part of the order's territorial possessions). History The Dutch Navy also used the rank of commandeur from the end of the 16th century for a variety of temporary positions, until it became a conventional permanent rank in 1955. The Royal Netherlands Air Force has adopted the English spelling of "commodore" for an equivalent rank.

the divergence theorem, such a field is necessarily a conservative one, and it is free from sources or sinks, having net flux equal to zero through any open domain without holes. (These two observations combine as real and imaginary parts in Cauchy's integral theorem.) In fluid dynamics, such a vector field is a potential flow. In magnetostatics, such vector fields model static magnetic fields on a region of the plane containing no current. In electrostatics, they model static electric fields in a region of the plane containing no electric charge. This interpretation can equivalently be restated in the language of differential forms. The pair u,v satisfy the Cauchy–Riemann equations if and only if the one-form is both closed and coclosed (a harmonic differential form). Preservation of complex structure Another formulation of the Cauchy–Riemann equations involves the complex structure in the plane, given by This is a complex structure in the sense that the square of J is the negative of the 2×2 identity matrix: . As above, if u(x,y),v(x,y) are two functions in the plane, put The Jacobian matrix of f is the matrix of partial derivatives Then the pair of functions u, v satisfies the Cauchy–Riemann equations if and only if the 2×2 matrix Df commutes with J. This interpretation is useful in symplectic geometry, where it is the starting point for the study of pseudoholomorphic curves. Other representations Other representations of the Cauchy–Riemann equations occasionally arise in other coordinate systems. If (1a) and (1b) hold for a differentiable pair of functions u and v, then so do for any coordinate system such that the pair (∇n, ∇s) is orthonormal and positively oriented. As a consequence, in particular, in the system of coordinates given by the polar representation {{math|1=z = ''r'eiθ}}, the equations then take the form Combining these into one equation for gives The inhomogeneous Cauchy–Riemann equations consist of the two equations for a pair of unknown functions and of two real variables for some given functions and defined in an open subset of R2. These equations are usually combined into a single equation where f = u + iv and 𝜑 = (α + iβ)/2. If 𝜑 is Ck, then the inhomogeneous equation is explicitly solvable in any bounded domain D, provided 𝜑 is continuous on the closure of D. Indeed, by the Cauchy integral formula, for all ζ ∈ D. Generalizations Goursat's theorem and its generalizations Suppose that is a complex-valued function which is differentiable as a function . Then Goursat's theorem asserts that f is analytic in an open complex domain Ω if and only if it satisfies the Cauchy–Riemann equation in the domain. In particular, continuous differentiability of f need not be assumed. The hypotheses of Goursat's theorem can be weakened significantly. If is continuous in an open set Ω and the partial derivatives of f with respect to x and y exist in Ω, and satisfy the Cauchy–Riemann equations throughout Ω, then f is holomorphic (and thus analytic). This result is the Looman–Menchoff theorem. The hypothesis that f obey the Cauchy–Riemann equations throughout the domain Ω is essential. It is possible to construct a continuous function satisfying the Cauchy–Riemann equations at a point, but which is not analytic at the point (e.g., . Similarly, some additional assumption is needed besides the Cauchy–Riemann equations (such as continuity), as the following example illustrates which satisfies the Cauchy–Riemann equations everywhere, but fails to be continuous at z = 0. Nevertheless, if a function satisfies the Cauchy–Riemann equations in an open set in a weak sense, then the function is analytic. More precisely: If f(z) is locally integrable in an open domain Ω ⊂ C, and satisfies the Cauchy–Riemann
be written in complex form In this form, the equations correspond structurally to the condition that the Jacobian matrix is of the form where and . A matrix of this form is the matrix representation of a complex number. Geometrically, such a matrix is always the composition of a rotation with a scaling, and in particular preserves angles. The Jacobian of a function takes infinitesimal line segments at the intersection of two curves in z and rotates them to the corresponding segments in . Consequently, a function satisfying the Cauchy–Riemann equations, with a nonzero derivative, preserves the angle between curves in the plane. That is, the Cauchy–Riemann equations are the conditions for a function to be conformal. Moreover, because the composition of a conformal transformation with another conformal transformation is also conformal, the composition of a solution of the Cauchy–Riemann equations with a conformal map must itself solve the Cauchy–Riemann equations. Thus the Cauchy–Riemann equations are conformally invariant. Complex differentiability Suppose that is a function of a complex number . Then the complex derivative of at a point is defined by provided this limit exists. If this limit exists, then it may be computed by taking the limit as along the real axis or imaginary axis; in either case it should give the same result. Approaching along the real axis, one finds On the other hand, approaching along the imaginary axis, The equality of the derivative of taken along the two axes is which are the Cauchy–Riemann equations (2) at the point . Conversely, if is a function which is differentiable when regarded as a function on , then f is complex differentiable if and only if the Cauchy–Riemann equations hold. In other words, if and are real-differentiable functions of two real variables, obviously is a (complex-valued) real-differentiable function, but is complex-differentiable if and only if the Cauchy–Riemann equations hold. Indeed, following Rudin, suppose f is a complex function defined in an open set . Then, writing for every , one can also regard Ω as an open subset of R2, and f as a function of two real variables x and y, which maps to C. We consider the Cauchy–Riemann equations at . So assume f is differentiable at , as a function of two real variables from Ω to C. This is equivalent to the existence of the following linear approximation where and as . Since and , the above can be re-written as Defining the two Wirtinger derivatives as in the limit the above equality can be written as Now consider the potential values of when the limit is taken at the origin. For z along the real line, so that . Similarly for purely imaginary z we have so that the value of is not well defined at the origin. It's easy to verify that is not well defined at any complex z, hence f is complex differentiable at z0 if and only if at . But this is exactly the Cauchy–Riemann equations, thus f is differentiable at z0 if and only if the Cauchy–Riemann equations hold at z0. Independence of the complex conjugate The above proof suggests another interpretation of the Cauchy–Riemann equations. The complex conjugate of z, denoted , is defined by for real x and y. The Cauchy–Riemann equations can then be written as a single equation by using the Wirtinger derivative with respect to the conjugate variable. In this form, the Cauchy–Riemann equations can be interpreted as the statement that f is independent of the variable . As such, we can view analytic functions as true functions of one complex variable as opposed to complex functions of two real variables. Physical interpretation A standard physical interpretation of the Cauchy–Riemann equations going back to Riemann's work on function theory is that u represents a velocity potential of an incompressible steady fluid flow in the plane, and v is its stream function. Suppose that the pair of (twice continuously differentiable) functions satisfies the Cauchy–Riemann equations. We will take u to be a velocity potential, meaning that we imagine a flow of fluid in the plane such that the velocity vector of the fluid at each point of the plane is equal to the gradient of u, defined by By differentiating the Cauchy–Riemann equations a second time, one shows that u solves Laplace's equation: That is, u is a harmonic function. This means that the divergence of the gradient is zero, and so the fluid is incompressible. The function v also satisfies the Laplace equation, by a similar analysis. Also, the Cauchy–Riemann equations imply that the dot product . This implies that the gradient of u must point along the curves; so these are the streamlines of the flow. The curves are the equipotential curves of the flow. A holomorphic function can therefore be visualized by plotting the two families of level curves and . Near points where the gradient of u (or, equivalently, v) is not zero, these families form an orthogonal family of curves. At the points where , the stationary points of the flow, the equipotential curves of intersect. The streamlines also intersect at the same point, bisecting the angles formed by the equipotential curves. Harmonic vector field Another interpretation of the Cauchy–Riemann equations can be found in Pólya & Szegő. Suppose that u and v satisfy the Cauchy–Riemann equations in an open subset of R2, and consider the vector field regarded as a (real) two-component vector. Then the second Cauchy–Riemann equation () asserts that is irrotational (its curl is 0): The first Cauchy–Riemann equation () asserts that the vector field is solenoidal (or divergence-free): Owing respectively to Green's theorem and the divergence theorem, such a field is necessarily a conservative one, and it is free from sources or sinks, having net flux equal to zero through any open domain without holes. (These two observations combine as real and imaginary parts in Cauchy's integral theorem.) In fluid dynamics, such a
in the early 1930s where he worked as a plasterer; he also served in the Haganah paramilitary organization. His mother, Imrela "Rel" (née Goldman) Topol, was a seamstress. Both of Topol's parents had been involved in the Betar Zionist youth movement before immigrating. His father had Hasidic roots, with a mother coming from a family of Gerrer Hasidim, while his father came from Aleksander Hasidim. Chaim and his two younger sisters grew up in the South Tel Aviv working-class neighborhood of Florentin. As a young child, although he wanted to become a commercial artist, his elementary school teacher, the writer Yemima Avidar-Tchernovitz, saw a theatrical side to him, and encouraged him to act in school plays and read stories to the class. At age 14 he began working as a printer at the Davar newspaper while pursuing his high school studies at night. He graduated high school at age 17 and moved to Kibbutz Geva. A year later, he enlisted in the Israeli army and became a member of the Nahal entertainment troupe, singing and acting in traveling shows. He rose in rank to troupe commander. Twenty-three days after being discharged from military service on October 2, 1956, and two days after marrying Galia Finkelstein, a fellow Nahal troupe member, Topol was called up for reserve duty in the Sinai Campaign. He performed for soldiers stationed in the desert. After the war, he and his wife settled in Kibbutz Mishmar David, where Topol worked as a garage mechanic. Topol assembled a kibbutz theatre company made up of friends from his Nahal troupe; the group toured four days a week, worked on their respective kibbutzim for two days a week, and had one day off. The theatre company was in existence from early 1957 to the mid-1960s. Topol both sang and acted with the group, doing both "loudly". Between 1960 and 1964, Topol performed with the Batzal Yarok ("Green Onion") satirical theatre company, which also toured Israel. Other members of the group included Uri Zohar, Nechama Hendel, Zaharira Harifai, Arik Einstein, and Oded Kotler. In 1960, Topol co-founded the Haifa Municipal Theatre with Yosef Milo, serving as assistant to the director and acting in plays by Shakespeare, Ionesco, and Brecht. In 1965 he performed in the Cameri Theatre in Tel Aviv. Early film career Topol's first film appearance was in the 1961 film I Like Mike, followed by the 1963 Israeli film El Dorado. His breakthrough role came as the lead character in the 1964 film Sallah Shabati. Adapted for the screen by Ephraim Kishon from his original play, the social satire depicts the hardships of a Sephardic immigrant family in the rough conditions of ma'abarot, immigrant absorption camps in Israel in the 1950s, satirizing "just about every pillar of Israeli society: the Ashkenazi establishment, the pedantic bureaucracy, corrupt political parties, rigid kibbutz ideologues and ... the Jewish National Fund's tree-planting program". Topol, who was 29 during the filming, was familiar playing the role of the family patriarch, having performed skits from the play with his Nahal entertainment troupe during his army years. He contributed his own ideas for the part, playing the character as a more universal Mizrahi Jew instead of specifically a Yemenite, Iraqi, or Moroccan Jew, and asking Kishon to change the character's first name from Saadia (a recognizably Yemenite name) to Sallah (a more general Mizrahi name). The film won the Golden Globe Award for Best Foreign Language Film, and Topol won the 1964 Golden Gate Award for Best Actor at the San Francisco International Film Festival and the 1965 Golden Globe for Most Promising Newcomer—Male, alongside Harve Presnell and George Segal. Sallah Shabati was nominated for the Academy Award for Best Foreign Language Film, losing to the Italian-language Yesterday, Today and Tomorrow. In 1966, Topol made his English-language film debut as Abou Ibn Kaqden in the Mickey Marcus biopic Cast a Giant Shadow. Tevye the Dairyman Topol came to greatest prominence in his portrayal of Tevye the Dairyman on stage and screen. He first played the lead role in the Israeli production of the musical Fiddler on the Roof in 1966, replacing Shmuel Rodensky for 10 weeks when Rodensky fell ill.

film portrayal of Tevye, and was nominated for a Tony Award for Best Actor for a 1991 Broadway revival of Fiddler on the Roof. He is a founder of Variety Israel, an organization serving children with special needs, and Jordan River Village, a year-round camp for Arab and Jewish children with life-threatening illnesses, for which he serves as chairman of the board. In 2015 he was awarded the Israel Prize for lifetime achievement. Early life Topol was born on September 9, 1935, in Tel Aviv, in what was then Mandatory Palestine (now Israel). His father, Jacob Topol, was Russian and immigrated to Mandatory Palestine in the early 1930s where he worked as a plasterer; he also served in the Haganah paramilitary organization.

Not yet fluent in English, Topol memorized the score from
following the death of John Thomas in 1871, and helped craft the structures of the Christadelphian body. Initially, the denomination grew in the English-speaking world, particularly in the English Midlands and in parts of North America. In the early days after the death of John Thomas, the group could have moved in a number of directions. Doctrinal issues arose, debates took place, and statements of faith were created and amended as other issues arose. These attempts were felt necessary by many to both settle and define a doctrinal stance for the newly emerging denomination and to keep out error. As a result of these debates, several groups separated from the main body of Christadelphians, most notably the Suffolk Street fellowship (with members believing that the whole of the Bible wasn't inspired) and the Unamended fellowship. 20th century The Christadelphian position on conscientious objection came to the fore with the introduction of conscription during the First World War. Varying degrees of exemption from military service were granted to Christadelphians in the United Kingdom, Canada, Australia, New Zealand, and the United States. In the Second World War, this frequently required the person seeking exemption to undertake civilian work under the direction of the authorities. During the Second World War, the Christadelphians in Britain assisted in the Kindertransport, helping to relocate several hundred Jewish children away from Nazi persecution by founding a hostel, Elpis Lodge, for that purpose. In Germany, the small Christadelphian community founded by Albert Maier went underground from 1940 to 1945, and a leading brother, Albert Merz, was imprisoned as a conscientious objector and later executed. After the Second World War, moves were taken to try to reunite various of the earlier divisions. By the end of the 1950s, most Christadelphians had united into one community, but there are still a number of small groups of Christadelphians who remain separate. Today The post-war and post-reunions periods saw an increase in co-operation and interaction between ecclesias, resulting in the establishment of a number of week-long Bible schools and the formation of national and international organisations such as the Christadelphian Bible Mission (for preaching and pastoral support overseas), the Christadelphian Support Network (for counselling), and the Christadelphian Meal-A-Day Fund (for charity and humanitarian work). The period following the reunions was accompanied by expansion in the developing world, which now accounts for around 40% of Christadelphians. Beliefs Due to the way the Christadelphian body is organised there is no central authority to establish and maintain a standardised set of beliefs and it depends upon what statement of faith is adhered to and how liberal the ecclesia is, but there are core doctrines most Christadelphians would accept. In the formal statements of faith a more complete list is found; for instance the Birmingham Amended Statement of Faith has 30 doctrines to be accepted and 35 to be rejected. The Bible Christadelphians state that their beliefs are based wholly on the Bible, and they do not see other works as inspired by God. They regard the Bible as inspired by God and, therefore, believe that in its original form, it is error-free apart from errors in later copies due to errors of transcription or translation. Based on this, Christadelphians teach what they believe as true Bible teaching. God Christadelphians believe that God, Yahweh, is the creator of all things and the father of true believers, that he is a separate being from his son, Jesus (who is subordinate to him), and that the Holy Spirit is the power of God used in creation and for salvation. They also believe that the phrase Holy Spirit sometimes refers to God's character/mind, depending on the context in which the phrase appears, but reject the view that people need strength, guidance and power from the Holy Spirit to live the Christian life, believing instead that the spirit a believer needs within themselves is the mind/character of God, which is developed in a believer by their reading of the Bible (which, they believe, contains words God gave by his Spirit) and trying to live by what it says during the events of their lives which God uses to help shape their character. Jesus Christadelphians believe that Jesus is the promised Jewish Messiah, in whom the prophecies and promises of the Old Testament find their fulfilment. They believe he is the Son of Man, in that he inherited human nature (with its inclination to sin) from his mother, and the Son of God by virtue of his miraculous conception by the power of God. Christadelphians also reject the doctrine of Christ's pre-existence. They teach that he was part of God's plans from the beginning and was foreshadowed in the Old Testament, but was no independent creature prior to his earthly birth. Although he was tempted, Jesus committed no sin, and was therefore a perfect representative sacrifice to bring salvation to sinful humankind. They believe that God raised Jesus from death and gave him immortality, and he ascended to Heaven, God's dwelling place. Christadelphians believe that he will return to the Earth in person to set up the Kingdom of God in fulfilment of the promises made to Abraham and David. This includes the belief that the coming Kingdom will be the restoration of God's first Kingdom of Israel, which was under David and Solomon. For Christadelphians, this is the focal point of the gospel taught by Jesus and the apostles. Devil Christadelphians believe that the Satan or Devil is not an independent spiritual being or fallen angel. Devil is viewed as the general principle of evil and inclination to sin which resides in humankind. They believe that, dependent on the context, the term HaSatan in Hebrew merely means "opponent" or "adversary" and is frequently applied to human beings. Accordingly, they do not define Hell as a place of eternal torment for sinners, but as a State of Eternal Death; respectively, non-existence due to annihilation of body and mind. Salvation Christadelphians believe that people are separated from God because of their sins but that humankind can be reconciled to him by becoming disciples of Jesus Christ. This is by belief in the gospel, through repentance, and through baptism by total immersion in water. They reject assurance of salvation, believing instead that salvation comes as a result of remaining "in Christ". After death, believers are in a state of non-existence, knowing nothing until the Resurrection at the return of Christ. Following the judgement at that time, the accepted receive the gift of immortality, and live with Christ on a restored Earth, assisting him to establish the Kingdom of God and to rule over the mortal population for a thousand years (the Millennium). Christadelphians believe that the Kingdom will be centred upon Israel, but Jesus Christ will also reign over all the other nations on the Earth. Some unorthodox Christadelphians believe that the Kingdom itself is not worldwide but limited to the land of Israel promised to Abraham and ruled over in the past by David, with a worldwide empire. Life in Christ The Commandments of Christ demonstrates the community's recognition of the importance of biblical teaching on morality. Marriage and family life are important. Christadelphians believe that sexual relationships should be limited to heterosexual marriage, ideally between baptised believers. Organisation General organisation In the absence of centralised organisation, some differences exist amongst Christadelphians on matters of belief and practice. This is because each congregation (commonly styled 'ecclesias') is organised autonomously, typically following common practices which have altered little since the 19th century. Many avoid the word "church" due to its association with mainstream Christianity, and its focus on the building as opposed to the congregation. Most ecclesias have a constitution, which includes a 'Statement of Faith', a list of 'Doctrines to be Rejected' and a formalised list of 'The Commandments of Christ'. With no central authority, individual congregations are responsible for maintaining orthodoxy in belief and practice, and the statement of faith is seen by many as useful to this end. The statement of faith acts as the official standard of most ecclesias to determine fellowship within and between ecclesias, and as the basis for co-operation between ecclesias. Congregational discipline and conflict resolution are applied using various forms of consultation, mediation, and discussion, with disfellowship (similar to excommunication) being the final response to those with unorthodox practices or beliefs. The relative uniformity of organisation and practice is undoubtedly due to the influence of a booklet, written early in Christadelphian history by Robert Roberts, called A Guide to the Formation and Conduct of Christadelphian Ecclesias. It recommends a basically democratic arrangement by which congregational members elect 'brothers' to arranging and serving duties, and includes guidelines for the organisation of committees, as well as conflict resolution between congregational members and between congregations. Christadelphians do not have paid ministers. Male members (and increasingly female in some places) are assessed by the congregation for their eligibility to teach and perform other duties, which are usually assigned on a rotation basis, as opposed to having a permanently appointed preacher. Congregational governance typically follows a democratic model, with an elected arranging committee for each individual ecclesia. This unpaid committee is responsible for the day-to-day running of the ecclesia and is answerable to the rest of the ecclesia's members. Inter-ecclesial organisations co-ordinate the running of, among other things, Christadelphian schools and elderly care homes, the Christadelphian Isolation League (which cares for those prevented by distance or infirmity from attending an ecclesia regularly) and the publication of Christadelphian magazines. Adherents No official membership figures are published, but the Columbia Encyclopaedia gives an estimated figure of 50,000 Christadelphians, spread across approximately 120 countries. Estimates for the main centers of Christadelphian population are as follows: Australia (10,093), Mozambique (10,000), the United Kingdom (8,200), Malawi (7,000), United States (6,500), Canada (3,000), Kenya (2,700), New Zealand (1,785), and India (1,790),. Figures from Christadelphian mission organisations are as follows: Africa (24,100), Asia (4,000), the Caribbean (400), Europe (including Russia) (700), Latin America (275), and the Pacific (200). Fellowships The Christadelphian body consists of a number of fellowships – groups of ecclesias which associate with one another, often to the exclusion of ecclesias outside their group. They are to some degree localised. The Unamended Fellowship, for example, exists only in North America. Christadelphian fellowships have often been named after ecclesias or magazines who took a lead in developing a particular stance. The majority of Christadelphians today belong to what is commonly known as the Central Fellowship. The term "Central" came into use around 1933 to identify ecclesias worldwide who were in fellowship with the Birmingham (Central) Ecclesia. These were previously known as the "Temperance Hall Fellowship". The "Suffolk Street Fellowship" arose in 1885 over disagreements surrounding the inspiration of the Bible. Meanwhile, in Australia, division concerning the nature of Jesus Christ resulted in the formation of the "Shield Fellowship". Discussions in 1957–1958 resulted in a worldwide reunion between the majority Christadelphians of the "Temperance Hall Fellowship" and the minority "Suffolk Street Fellowship", closely followed in Australia by the minority "Shield Fellowship". The Unamended Fellowship, consisting of around 1,850 members, is found in the East Coast and Midwest USA and Ontario, Canada. This group separated in 1898 as a result of differing views on who would be raised to judgement at the return of Christ. The majority of Christadelphians believe that the judgement will include anyone who had sufficient knowledge of the gospel message, and is not limited to baptised believers. The majority in England, Australia and North America amended their statement of faith accordingly. Those who opposed the amendment became known as the "Unamended Fellowship" and allowed the teaching that God either could not or would not raise those who had no covenant relationship with him. Opinions vary as to what the established position was on this subject prior to the controversy. Prominent in the formation of the Unamended Fellowship was Thomas Williams, editor of the Christadelphian Advocate magazine. The majority of the Unamended Fellowship outside North America joined

Male members (and increasingly female in some places) are assessed by the congregation for their eligibility to teach and perform other duties, which are usually assigned on a rotation basis, as opposed to having a permanently appointed preacher. Congregational governance typically follows a democratic model, with an elected arranging committee for each individual ecclesia. This unpaid committee is responsible for the day-to-day running of the ecclesia and is answerable to the rest of the ecclesia's members. Inter-ecclesial organisations co-ordinate the running of, among other things, Christadelphian schools and elderly care homes, the Christadelphian Isolation League (which cares for those prevented by distance or infirmity from attending an ecclesia regularly) and the publication of Christadelphian magazines. Adherents No official membership figures are published, but the Columbia Encyclopaedia gives an estimated figure of 50,000 Christadelphians, spread across approximately 120 countries. Estimates for the main centers of Christadelphian population are as follows: Australia (10,093), Mozambique (10,000), the United Kingdom (8,200), Malawi (7,000), United States (6,500), Canada (3,000), Kenya (2,700), New Zealand (1,785), and India (1,790),. Figures from Christadelphian mission organisations are as follows: Africa (24,100), Asia (4,000), the Caribbean (400), Europe (including Russia) (700), Latin America (275), and the Pacific (200). Fellowships The Christadelphian body consists of a number of fellowships – groups of ecclesias which associate with one another, often to the exclusion of ecclesias outside their group. They are to some degree localised. The Unamended Fellowship, for example, exists only in North America. Christadelphian fellowships have often been named after ecclesias or magazines who took a lead in developing a particular stance. The majority of Christadelphians today belong to what is commonly known as the Central Fellowship. The term "Central" came into use around 1933 to identify ecclesias worldwide who were in fellowship with the Birmingham (Central) Ecclesia. These were previously known as the "Temperance Hall Fellowship". The "Suffolk Street Fellowship" arose in 1885 over disagreements surrounding the inspiration of the Bible. Meanwhile, in Australia, division concerning the nature of Jesus Christ resulted in the formation of the "Shield Fellowship". Discussions in 1957–1958 resulted in a worldwide reunion between the majority Christadelphians of the "Temperance Hall Fellowship" and the minority "Suffolk Street Fellowship", closely followed in Australia by the minority "Shield Fellowship". The Unamended Fellowship, consisting of around 1,850 members, is found in the East Coast and Midwest USA and Ontario, Canada. This group separated in 1898 as a result of differing views on who would be raised to judgement at the return of Christ. The majority of Christadelphians believe that the judgement will include anyone who had sufficient knowledge of the gospel message, and is not limited to baptised believers. The majority in England, Australia and North America amended their statement of faith accordingly. Those who opposed the amendment became known as the "Unamended Fellowship" and allowed the teaching that God either could not or would not raise those who had no covenant relationship with him. Opinions vary as to what the established position was on this subject prior to the controversy. Prominent in the formation of the Unamended Fellowship was Thomas Williams, editor of the Christadelphian Advocate magazine. The majority of the Unamended Fellowship outside North America joined the Suffolk Street fellowship before its eventual incorporation into Central fellowship. There is also some co-operation between the Central (Amended) and Unamended Fellowships in North America – most recently in the Great Lakes region, where numerous Amended and Unamended ecclesias are working together to unify their ecclesias. The "Central Fellowship" in North America is still often referred to today as the Amended Fellowship. The Berean Fellowship was formed in 1923 as a result of varying views on military service in England, and on the atonement in North America. The majority of the North American Bereans re-joined the main body of Christadelphians in 1952. A number continue as a separate community, numbering around 200 in Texas, 100 in Kenya and 30 in Wales. Most of the divisions still in existence within the Christadelphian community today stem from further divisions of the Berean Fellowship. The Dawn Fellowship are the result of an issue which arose in 1942 among the Berean Fellowship regarding divorce and remarriage. The stricter party formed the Dawn Fellowship who, following re-union on the basis of unity of belief with the Lightstand Fellowship in Australia in 2007 increased in number. There are now thought to be around 800 members in England, Australia, Canada, India, Jamaica, Poland, the Philippines, Russia and Kenya. The Old Paths Fellowship was formed in 1957 in response to the reunion of the Temperance Hall (Central) and Suffolk Street fellowships. A minority from the Temperance Hall (Central) fellowship held that the reasons for separation remained and that full unity of belief on all fundamental principles of Bible teaching was necessary; thus reunion was only possible with the full agreement and understanding of all members rather than a decision by majority vote. Ecclesias forming the Old Paths Fellowship arose in England, Australia, New Zealand and Canada numbering around 500 members in total. They now number around 250 members in total. They maintain that they hold to the original Central Fellowship position held prior to the 1957 Reunion. Other fellowships (ranging in numbers from as few as 10 to over 200 members) include the Watchman Fellowship, the Companion Fellowship and the Pioneer Fellowship. According to Bryan Wilson, functionally the definition of a "fellowship" within Christadelphian history has been mutual or unilateral exclusion of groupings of ecclesias from the breaking of bread. This functional definition still holds true in North America, where the Unamended Fellowship and the Church of God of the Abrahamic Faith are not received by most North American Amended ecclesias. But outside North America this functional definition no longer holds. Many articles and books on the doctrine and practice of fellowship now reject the notion itself of separate "fellowships" among those who recognise the same baptism, viewing such separations as schismatic. Many ecclesias in the Central fellowship would not refuse a baptised Christadelphian from a minority fellowship from breaking bread; the exclusion is more usually the other way. They tend to operate organisationally fairly similarly, although there are different emphases. Despite their differences, the Central, Old Paths, Dawn and Berean fellowships generally subscribe to the Birmingham Amended Statement of Faith (BASF), though the latter two have additional clauses or supporting documents to explain their position. Most Unamended ecclesias use the Birmingham Unamended Statement of Faith (BUSF) with one clause being different. Within the Central fellowship individual ecclesias also may have their own statement of faith, whilst still accepting the statement of faith of the larger community. Some ecclesias have statements around their positions, especially on divorce and re-marriage, making clear that offence would be caused by anyone in that position seeking to join them at the 'Breaking of Bread' service. Others tolerate a degree of divergence from commonly held Christadelphian views. While some communities of Christadelphian origin have viewed previous statements of faith as set in stone, others have felt it necessary to revise them in order to meet contemporary issues, update language or add supporting Biblical quotations. For each fellowship, anyone who publicly assents to the doctrines described in the statement and is in good standing in their "home ecclesia" is generally welcome to participate in the activities of any other ecclesia. Related groups There are a number of groups who, while sharing a common heritage and many Christadelphian teachings, have adopted alternative names in order to dissociate themselves from what they believe to be false teachings and/or practice within the main Christadelphian body. Ranging in size from two or three members in size to around 50, each group restricts fellowship to its own members. These include the Nazarene Fellowship, the Ecclesia of Christ, the Remnant of Christ's Ecclesia, the Apostolic Fellowship of Christ and the Apostolic Ecclesia. The Church of God of the Abrahamic Faith (CGAF) also has common origins with Christadelphians and shares Christadelphian beliefs. Numbering around 400 (primarily Ohio and Florida, USA), they are welcomed into fellowship by some "Central" Christadelphians and are currently involved in unity talks. Similarities and differences with other Christians Disagreement with some mainstream doctrines Christadelphians reject a number of doctrines held by many other Christians, notably the immortality of the soul (see also mortalism; conditionalism), trinitarianism, the personal pre-existence of Christ, the baptism of infants, the personhood of the Holy Spirit, the divinity of Jesus and the present-day possession of the Holy Spirit (both "gift of" and "gifts of") (see cessationism). They believe that the word devil is a reference in the scriptures to sin and human nature in opposition to God, while the word satan is merely a reference to an adversary (be it good or bad). According to Christadelphians, these terms are used in reference to specific political systems or individuals in opposition or conflict. Hell (Hebrew: Sheol, Gehenna; Greek: Hades, Tartarus) is understood to refer exclusively to death and the grave, rather than being a place of everlasting torment (see also annihilationism). Christadelphians do not believe that anyone will "go to Heaven" upon death. Instead, they believe that only Jesus Christ went to Heaven, and when he comes back to the Earth there will be a resurrection and God's Kingdom will be established on Earth, starting in the land of Israel. Christadelphians believe the doctrines they reject were introduced into Christendom after the 1st century in large part through exposure to pagan Greek philosophy, and cannot be substantiated from the Biblical texts. Other historical groups and individuals with some shared doctrines One criticism of the Christadelphian movement has been over the claim of John Thomas and Robert Roberts to have "re-discovered" scriptural truth. However one might argue that all Protestant groups make the same claims to some extent. Although both men believed that they had "recovered" the true doctrines for themselves and contemporaries, they also believed there had always existed a group of true believers throughout the ages, albeit marred by the apostasy.

utility lines. Coaxial cable brings the signal to the customer's building through a service drop, an overhead or underground cable. If the subscriber's building does not have a cable service drop, the cable company will install one. The standard cable used in the U.S. is RG-6, which has a 75 ohm impedance, and connects with a type F connector. The cable company's portion of the wiring usually ends at a distribution box on the building exterior, and built-in cable wiring in the walls usually distributes the signal to jacks in different rooms to which televisions are connected. Multiple cables to different rooms are split off the incoming cable with a small device called a splitter. There are two standards for cable television; older analog cable, and newer digital cable which can carry data signals used by digital television receivers such as high-definition television (HDTV) equipment. All cable companies in the United States have switched to or are in the course of switching to digital cable television since it was first introduced in the late 1990s. Most cable companies require a set-top box (cable converter box) or a slot on one's TV set for conditional access module cards to view their cable channels, even on newer televisions with digital cable QAM tuners, because most digital cable channels are now encrypted, or "scrambled", to reduce cable service theft. A cable from the jack in the wall is attached to the input of the box, and an output cable from the box is attached to the television, usually the RF-IN or composite input on older TVs. Since the set-top box only decodes the single channel that is being watched, each television in the house requires a separate box. Some unencrypted channels, usually traditional over-the-air broadcast networks, can be displayed without a receiver box. The cable company will provide set-top boxes based on the level of service a customer purchases, from basic set-top boxes with a standard definition picture connected through the standard coaxial connection on the TV, to high-definition wireless digital video recorder (DVR) receivers connected via HDMI or component. Older analog television sets are "cable ready" and can receive the old analog cable without a set-top box. To receive digital cable channels on an analog television set, even unencrypted ones, requires a different type of box, a digital television adapter supplied by the cable company or purchased by the subscriber. Another new distribution method that takes advantage of the low cost high quality DVB distribution to residential areas, uses TV gateways to convert the DVB-C, DVB-C2 stream to IP for distribution of TV over IP network in the home. Many cable companies offer internet access through DOCSIS. Principle of operation In the most common system, multiple television channels (as many as 500, although this varies depending on the provider's available channel capacity) are distributed to subscriber residences through a coaxial cable, which comes from a trunkline supported on utility poles originating at the cable company's local distribution facility, called the "headend". Many channels can be transmitted through one coaxial cable by a technique called frequency division multiplexing. At the headend, each television channel is translated to a different frequency. By giving each channel a different frequency "slot" on the cable, the separate television signals do not interfere with each other. At an outdoor cable box on the subscriber's residence, the company's service drop cable is connected to cables distributing the signal to different rooms in the building. At each television, the subscriber's television or a set-top box provided by the cable company translates the desired channel back to its original frequency (baseband), and it is displayed onscreen. Due to widespread cable theft in earlier analog systems, the signals are typically encrypted on modern digital cable systems, and the set-top box must be activated by an activation code sent by the cable company before it will function, which is only sent after the subscriber signs up. If the subscriber fails to pay their bill, the cable company can send a signal to deactivate the subscriber's box, preventing reception. There are also usually "upstream" channels on the cable to send data from the customer box to the cable headend, for advanced features such as requesting pay-per-view shows or movies, cable internet access, and cable telephone service. The "downstream" channels occupy a band of frequencies from approximately 50 MHz to 1 GHz, while the "upstream" channels occupy frequencies of 5 to 42 MHz. Subscribers pay with a monthly fee. Subscribers can choose from several levels of service, with "premium" packages including more channels but costing a higher rate. At the local headend, the feed signals from the individual television channels are received by dish antennas from communication satellites. Additional local channels, such as local broadcast television stations, educational channels from local colleges, and community access channels devoted to local governments (PEG channels) are usually included on the cable service. Commercial advertisements for local business are also inserted in the programming at the headend (the individual channels, which are distributed nationally, also have their own nationally oriented commercials). Hybrid fiber-coaxial Modern cable systems are large, with a single network and headend often serving an entire metropolitan area. Most systems use hybrid fiber-coaxial (HFC) distribution; this means the trunklines that carry the signal from the headend to local neighborhoods are optical fiber to provide greater bandwidth and also extra capacity for future expansion. At the headend, the electrical signal is translated into an optical signal and sent through the fiber. The fiber trunkline goes to several distribution hubs, from which multiple fibers fan out to carry the signal to boxes called optical nodes
broadcasters were forced to either install scrambling circuitry or move these signals further out of the range of reception for early cable-ready TVs and VCRs. However, once consumer sets had the ability to receive all 181 FCC allocated channels, premium broadcasters were left with no choice but to scramble. Unfortunately for pay-TV operators, the descrambling circuitry was often published in electronics hobby magazines such as Popular Science and Popular Electronics allowing anybody with anything more than a rudimentary knowledge of broadcast electronics to be able to build their own and receive the programming without cost. Later, the cable operators began to carry FM radio stations, and encouraged subscribers to connect their FM stereo sets to cable. Before stereo and bilingual TV sound became common, Pay-TV channel sound was added to the FM stereo cable line-ups. About this time, operators expanded beyond the 12-channel dial to use the "midband" and "superband" VHF channels adjacent to the "high band" 7–13 of North American television frequencies. Some operators as in Cornwall, Ontario, used a dual distribution network with Channels 2–13 on each of the two cables. During the 1980s, United States regulations not unlike public, educational, and government access (PEG) created the beginning of cable-originated live television programming. As cable penetration increased, numerous cable-only TV stations were launched, many with their own news bureaus that could provide more immediate and more localized content than that provided by the nearest network newscast. Such stations may use similar on-air branding as that used by the nearby broadcast network affiliate, but the fact that these stations do not broadcast over the air and are not regulated by the FCC, their call signs are meaningless. These stations evolved partially into today's over-the-air digital subchannels, where a main broadcast TV station e.g. NBS 37* would – in the case of no local CNB or ABS station being available – rebroadcast the programming from a nearby affiliate but fill in with its own news and other community programming to suit its own locale. Many live local programs with local interests were subsequently created all over the United States in most major television markets in the early 1980s. This evolved into today's many cable-only broadcasts of diverse programming, including cable-only produced television movies and miniseries. Cable specialty channels, starting with channels oriented to show movies and large sporting or performance events, diversified further, and "narrowcasting" became common. By the late 1980s, cable-only signals outnumbered broadcast signals on cable systems, some of which by this time had expanded beyond 35 channels. By the mid-1980s in Canada, cable operators were allowed by the regulators to enter into distribution contracts with cable networks on their own. By the 1990s, tiers became common, with customers able to subscribe to different tiers to obtain different selections of additional channels above the basic selection. By subscribing to additional tiers, customers could get specialty channels, movie channels, and foreign channels. Large cable companies used addressable descramblers to limit access to premium channels for customers not subscribing to higher tiers, however the above magazines often published workarounds for that technology as well. During the 1990s, the pressure to accommodate the growing array of offerings resulted in digital transmission that made more efficient use of the VHF signal capacity; fibre optics was common to carry signals into areas near the home, where coax could carry higher frequencies over the short remaining distance. Although for a time in the 1980s and 1990s, television receivers and VCRs were equipped to receive the mid-band and super-band channels. Due to the fact that the descrambling circuitry was for a time present in these tuners, depriving the cable operator of much of their revenue, such cable-ready tuners are rarely used now – requiring a return to the set-top boxes used from the 1970s onward. The conversion to digital broadcasting has put all signals – broadcast and cable – into digital form, rendering analog cable television service mostly obsolete, functional in an ever-dwindling supply of select markets. Analog television sets are still accommodated, but their tuners are mostly obsolete, oftentimes dependent entirely on the set-top box. Deployments by continent Cable television is mostly available in North America, Europe, Australia, South Asia and East Asia, and less so in South America and the Middle East. Cable television has had little success in Africa, as it is not cost-effective to lay cables in sparsely populated areas. So-called "Wireless Cable" microwave-based systems are used instead. Other cable-based services Coaxial cables are capable of bi-directional carriage of signals as well as the transmission of large amounts of data. Cable television signals use only a portion of the bandwidth available over coaxial lines. This leaves plenty of space available for other digital services such as cable internet, cable telephony and wireless services, using both unlicensed and licensed spectrum. Broadband internet access is achieved over coaxial cable by using cable modems to convert the network data into a type of digital signal that can be transferred over coaxial cable. One problem with some cable systems is the older amplifiers placed along the cable routes are unidirectional thus in order to allow for uploading of data the customer would need to use an analog telephone modem to provide for the upstream connection. This limited the upstream speed to 31.2 Kbp/s and prevented the always-on convenience broadband internet typically provides. Many large cable systems have upgraded or are upgrading their equipment to allow for bi-directional signals, thus allowing for greater upload speed and always-on convenience, though these upgrades are expensive. In North America, Australia and Europe, many cable operators have already introduced cable telephone service, which operates just like existing fixed line operators. This service involves installing a special telephone interface at the customer's premises that converts the analog signals from the customer's in-home wiring into a digital signal, which is then sent on the local loop (replacing the analog last mile, or plain old telephone service (POTS) to the company's switching center, where it is connected to the public switched telephone network (PSTN). The biggest obstacle to cable telephone service is the need for nearly 100% reliable service for emergency calls. One of the standards available for digital cable telephony, PacketCable, seems to be the most promising and able to work with the quality of service (QOS) demands of traditional analog plain old telephone service (POTS) service. The biggest advantage to digital cable telephone service is similar to the advantage of digital cable, namely that data can be compressed, resulting in much less bandwidth used than a dedicated analog circuit-switched service. Other advantages include better voice quality and integration to a Voice over Internet Protocol (VoIP) network providing cheap or unlimited nationwide and international calling. In many cases, digital cable telephone service is separate from cable modem service being offered by many cable companies and does not rely on Internet Protocol (IP) traffic or the Internet. Traditional cable television providers and traditional telecommunication companies increasingly compete in providing voice, video and data services to residences. The combination of television, telephone and Internet access is commonly called "triple play", regardless of whether CATV or telcos offer it.

for the most vulnerable. For prevention to be effective, it is important that cases be reported to national health authorities. Vaccination Spanish physician Jaume Ferran i Clua developed a cholera inoculation in 1885, the first to immunize humans against a bacterial disease. However, his vaccine and inoculation was rather controversial and was rejected by his peers and several investigation commissions. Russian-Jewish bacteriologist Waldemar Haffkine successfully developed the first human cholera vaccine in July 1892. He conducted a massive inoculation program in British India. A number of safe and effective oral vaccines for cholera are available. The World Health Organization (WHO) has three prequalified oral cholera vaccines (OCVs): Dukoral, Sanchol, and Euvichol. Dukoral, an orally administered, inactivated whole cell vaccine, has an overall efficacy of about 52% during the first year after being given and 62% in the second year, with minimal side effects. It is available in over 60 countries. However, it is not currently recommended by the Centers for Disease Control and Prevention (CDC) for most people traveling from the United States to endemic countries. The vaccine that the US Food and Drug Administration (FDA) recommends, Vaxchora, is an oral attenuated live vaccine, that is effective as a single dose. One injectable vaccine was found to be effective for two to three years. The protective efficacy was 28% lower in children less than five years old. However, , it has limited availability. Work is under way to investigate the role of mass vaccination. The WHO recommends immunization of high-risk groups, such as children and people with HIV, in countries where this disease is endemic. If people are immunized broadly, herd immunity results, with a decrease in the amount of contamination in the environment. WHO recommends that oral cholera vaccination be considered in areas where the disease is endemic (with seasonal peaks), as part of the response to outbreaks, or in a humanitarian crisis during which the risk of cholera is high. Oral Cholera Vaccine (OCV) has been recognized as an adjunct tool for prevention and control of cholera. The World Health Organization (WHO) has prequalified three bivalent cholera vaccines—Dukoral (SBL Vaccines), containing a non-toxic B-subunit of cholera toxin and providing protection against V. cholerae O1; and two vaccines developed using the same transfer of technology—ShanChol (Shantha Biotec) and Euvichol (EuBiologics Co.), which have bivalent O1 and O139 oral killed cholera vaccines. Oral cholera vaccination could be deployed in a diverse range of situations from cholera-endemic areas and locations of humanitarian crises, but no clear consensus exists. Sari filtration Developed for use in Bangladesh, the "sari filter" is a simple and cost-effective appropriate technology method for reducing the contamination of drinking water. Used sari cloth is preferable but other types of used cloth can be used with some effect, though the effectiveness will vary significantly. Used cloth is more effective than new cloth, as the repeated washing reduces the space between the fibers. Water collected in this way has a greatly reduced pathogen count—though it will not necessarily be perfectly safe, it is an improvement for poor people with limited options. In Bangladesh this practice was found to decrease rates of cholera by nearly half. It involves folding a sari four to eight times. Between uses the cloth should be rinsed in clean water and dried in the sun to kill any bacteria on it. A nylon cloth appears to work as well but is not as affordable. Treatment Continued eating speeds the recovery of normal intestinal function. The WHO recommends this generally for cases of diarrhea no matter what the underlying cause. A CDC training manual specifically for cholera states: "Continue to breastfeed your baby if the baby has watery diarrhea, even when traveling to get treatment. Adults and older children should continue to eat frequently." Fluids The most common error in caring for patients with cholera is to underestimate the speed and volume of fluids required. In most cases, cholera can be successfully treated with oral rehydration therapy (ORT), which is highly effective, safe, and simple to administer. Rice-based solutions are preferred to glucose-based ones due to greater efficiency. In severe cases with significant dehydration, intravenous rehydration may be necessary. Ringer's lactate is the preferred solution, often with added potassium. Large volumes and continued replacement until diarrhea has subsided may be needed. Ten percent of a person's body weight in fluid may need to be given in the first two to four hours. This method was first tried on a mass scale during the Bangladesh Liberation War, and was found to have much success. Despite widespread beliefs, fruit juices and commercial fizzy drinks like cola are not ideal for rehydration of people with serious infections of the intestines, and their excessive sugar content may even harm water uptake. If commercially produced oral rehydration solutions are too expensive or difficult to obtain, solutions can be made. One such recipe calls for 1 liter of boiled water, 1/2 teaspoon of salt, 6 teaspoons of sugar, and added mashed banana for potassium and to improve taste. Electrolytes As there frequently is initially acidosis, the potassium level may be normal, even though large losses have occurred. As the dehydration is corrected, potassium levels may decrease rapidly, and thus need to be replaced. This may be done by consuming foods high in potassium, like bananas or coconut water. Antibiotics Antibiotic treatments for one to three days shorten the course of the disease and reduce the severity of the symptoms. Use of antibiotics also reduces fluid requirements. People will recover without them, however, if sufficient hydration is maintained. The WHO only recommends antibiotics in those with severe dehydration. Doxycycline is typically used first line, although some strains of V. cholerae have shown resistance. Testing for resistance during an outbreak can help determine appropriate future choices. Other antibiotics proven to be effective include cotrimoxazole, erythromycin, tetracycline, chloramphenicol, and furazolidone. Fluoroquinolones, such as ciprofloxacin, also may be used, but resistance has been reported. Antibiotics improve outcomes in those who are both severely and not severely dehydrated. Azithromycin and tetracycline may work better than doxycycline or ciprofloxacin. Zinc supplementation In Bangladesh zinc supplementation reduced the duration and severity of diarrhea in children with cholera when given with antibiotics and rehydration therapy as needed. It reduced the length of disease by eight hours and the amount of diarrhea stool by 10%. Supplementation appears to be also effective in both treating and preventing infectious diarrhea due to other causes among children in the developing world. Prognosis If people with cholera are treated quickly and properly, the mortality rate is less than 1%; however, with untreated cholera, the mortality rate rises to 50–60%. For certain genetic strains of cholera, such as the one present during the 2010 epidemic in Haiti and the 2004 outbreak in India, death can occur within two hours of becoming ill. Epidemiology Cholera affects an estimated 2.8 million people worldwide, and causes approximately 95,000 deaths a year (uncertainty range: 21,000-143,000) . This occurs mainly in the developing world. In the early 1980s, death rates are believed to have been greater than three million a year. It is difficult to calculate exact numbers of cases, as many go unreported due to concerns that an outbreak may have a negative impact on the tourism of a country. Cholera remains both epidemic and endemic in many areas of the world. In October 2016, an outbreak of cholera began in war-ravaged Yemen. WHO called it "the worst cholera outbreak in the world". Recent major outbreaks are the 2010s Haiti cholera outbreak and the 2016–2021 Yemen cholera outbreak. In 2019, 93% of the reported 923,037 cholera cases were from Yemen (with 1911 deaths reported). Between September 2019 and September 2020, a global total of over 450,000 cases and over 900 deaths was reported; however these numbers suffer from over-reporting from countries that report suspected cases (and not laboratory confirmed cases) as well as under-reporting from countries that do not report official cases (such as Bangladesh, India and Philippines). Although much is known about the mechanisms behind the spread of cholera, this has not led to a full understanding of what makes cholera outbreaks happen in some places and not others. Lack of treatment of human feces and lack of treatment of drinking water greatly facilitate its spread, but bodies of water can serve as a reservoir, and seafood shipped long distances can spread the disease. Cholera was not known in the Americas for most of the 20th century, but it reappeared towards the end of that century. After the end of the 2010s Haiti cholera outbreak, there have not been any cholera cases in the Americas since February 2019. the disease is endemic in Africa and some areas of Asia (Bangladesh, India and Yemen). Cholera is not endemic in Europe, all reported cases had a travel history to endemic areas. History of outbreaks The word cholera is from kholera from χολή kholē "bile". Cholera likely has its origins in the Indian subcontinent as evidenced by its prevalence in the region for centuries. The disease appears in the European literature as early as 1642, from the Dutch physician Jakob de Bondt's description it in his De Medicina Indorum. (The "Indorum" of the title refers to the East Indies. He also gave first European descriptions of other diseases.) Early outbreaks in the Indian subcontinent are believed to have been the result of poor living conditions as well as the presence of pools of still water, both of which provide ideal conditions for cholera to thrive. The disease first spread by trade routes (land and sea) to Russia in 1817, later to the rest of Europe, and from Europe to North America and the rest of the world, (hence the name "Asiatic cholera"). Seven cholera pandemics have occurred in the past 200 years, with the seventh pandemic originating in Indonesia in 1961. The first cholera pandemic occurred in the Bengal region of India, near Calcutta starting in 1817 through 1824. The disease dispersed from India to Southeast Asia, the Middle East, Europe, and Eastern Africa. The movement of British Army and Navy ships and personnel is believed to have contributed to the range of the pandemic, since the ships carried people with the disease to the shores of the Indian Ocean, from Africa to Indonesia, and north to China and Japan. The second pandemic lasted from 1826 to 1837 and particularly affected North America and Europe due to the result of advancements in transportation and global trade, and increased human migration, including soldiers. The third pandemic erupted in 1846, persisted until 1860, extended to North Africa, and reached South America, for the first time specifically affecting Brazil. The fourth pandemic lasted from 1863 to 1875 spread from India to Naples and Spain. The fifth pandemic was from 1881–1896 and started in India and spread to Europe, Asia, and South America. The sixth pandemic started 1899–1923. These epidemics were less fatal due to a greater understanding of the cholera bacteria. Egypt, the Arabian peninsula, Persia, India, and the Philippines were hit hardest during these epidemics, while other areas, like Germany in 1892 (primarily the city of Hamburg where more than 8.600 people died) and Naples from 1910–1911, also experienced severe outbreaks. The seventh pandemic originated in 1961 in Indonesia and is marked by the emergence of a new strain, nicknamed El Tor, which still persists () in developing countries. Cholera became widespread in the 19th century. Since then it has killed tens of millions of people. In Russia alone, between 1847 and 1851, more than one million people perished of the disease. It killed 150,000 Americans during the second pandemic. Between 1900 and 1920, perhaps eight million people died of cholera in India. Cholera became the first reportable disease in the United States due to the significant effects it had on health. John Snow, in England, was the first to identify the importance of contaminated water as its cause in 1854. Cholera is now no longer considered a pressing health threat in Europe and North America due to filtering and chlorination of water supplies, but still heavily affects populations in developing countries. In the past, vessels flew a yellow quarantine flag if any crew members or passengers were suffering from cholera. No one aboard a vessel flying a yellow flag would be allowed ashore for an extended period, typically 30 to 40 days. Historically many different claimed remedies have existed in folklore. Many of the older remedies were based on the miasma theory. Some believed that abdominal chilling made one more susceptible and flannel and cholera belts were routine in army kits. In the 1854–1855 outbreak in Naples homeopathic camphor was used according to Hahnemann. T. J. Ritter's "Mother's Remedies" book lists tomato syrup as a home remedy from northern America. Elecampane was recommended in the United Kingdom according to William Thomas Fernie. The first effective human vaccine was developed in 1885, and the first effective antibiotic was developed in 1948. Cholera cases are much less frequent in developed countries where governments have helped to establish water sanitation practices and effective medical treatments. The United States, for example, used to have a severe cholera problem similar to those in some developing countries. There were three large cholera outbreaks in the 1800s, which can be attributed to Vibrio cholerae'''s spread through interior waterways like the Erie Canal and routes along the Eastern Seaboard. The island of Manhattan in New York City touched the Atlantic Ocean, where cholera collected just off the coast. At this time, New York City did not have as effective a sanitation system as it does today, so cholera was able to spread. Cholera morbus is a historical term that was used to refer to gastroenteritis rather than specifically cholera. Research One of the major contributions to fighting cholera was made by the physician and pioneer medical scientist John Snow (1813–1858), who in 1854 found a link between cholera and contaminated drinking water. Dr. Snow proposed a microbial origin for epidemic cholera in 1849. In his major "state of the art" review of 1855, he proposed a substantially complete and correct model for the cause of the disease. In two pioneering epidemiological field studies, he was able to demonstrate human sewage contamination was the most probable disease vector in two major epidemics in London in 1854. His model was not immediately accepted, but it was seen to be the more plausible, as medical microbiology developed over the next 30 years or so. For his work on cholera, John Snow is often regarded as the "Father of Epidemiology". The bacterium was isolated in 1854 by Italian anatomist Filippo Pacini, but its exact nature and his results were not widely known. In the same year, the Catalan Joaquim Balcells i Pascual discovered the bacterium and in 1856 probably António Augusto da Costa Simões and José Ferreira de Macedo Pinto, two Portuguese men, did the same. Cities in developed nations made massive investment in clean water supply and well-separated sewage treatment infrastructures between the mid-1850s and the 1900s. This eliminated the threat of cholera epidemics from the major developed cities in the world. In 1883, Robert Koch identified V. cholerae with a microscope as the bacillus causing the disease. Hemendra Nath Chatterjee, a Bengali scientist, who first formulated and demonstrated the effectiveness of oral rehydration salt (ORS) for diarrhea. In his 1953 paper, published in The Lancet, he states that promethazine can stop vomiting during cholera and then oral rehydration is possible. The formulation of the fluid replacement solution was 4 g of sodium chloride, 25 g of glucose and 1000 ml of water. Indian medical scientist Sambhu Nath De discovered the cholera toxin, the animal model of cholera, and successfully demonstrate the method of transmission of cholera pathogen Vibrio cholerae. Robert Allan Phillips, working at the US Naval Medical Research Unit Two in Southeast Asia, evaluated the pathophysiology of the disease using modern laboratory chemistry techniques and developed a protocol for rehydration. His research led the Lasker Foundation to award him its prize in 1967. More recently, in 2002, Alam, et al., studied stool samples from patients at the International Centre for Diarrhoeal Disease in Dhaka, Bangladesh. From the various experiments they conducted, the researchers found a correlation between the passage of V. cholerae through the human digestive system and an increased infectivity state. Furthermore, the researchers found the bacterium creates a hyperinfected state where genes that control biosynthesis of amino acids, iron uptake systems, and formation of periplasmic nitrate reductase complexes were induced just before defecation. These induced characteristics allow the cholera vibrios to survive in the "rice water" stools, an environment of limited oxygen and iron, of patients with a cholera infection. Global Strategy In 2017, the WHO launched the "Ending Cholera: a global roadmap to 2030" strategy which aims to reduce cholera deaths by 90% by 2030. The strategy was developed by the Global Task Force on Cholera Control (GTFCC) which develops country-specific plans and monitors progress. The approach to achieve this goal combines surveillance, water sanitation, treatment and oral vaccines. Specifically, the control strategy focusses on three approaches: i) early detection and response to outbreaks to contain outbreaks, ii) stopping cholera transmission through improved sanitation and vaccines in hotspots, and iii) a global framework for cholera control through the GTFCC. The WHO and the GTFCC do not consider global cholera eradication a viable goal. Even though humans are the only host of cholera, the bacterium can persist in the environment without a human host. While global eradication is not possible, elimination of human to human transmission may be possible; and local elimination is possible, most recently during the 2010s Haiti cholera outbreak which aims to achieve certification of elimination by 2022. The GTFCC targets 47 countries, 13 of which have established vaccination campaigns. Society and culture Health policy In many developing countries, cholera still reaches its victims through contaminated water sources, and countries without proper sanitation techniques have greater incidence of the disease. Governments can play a role in this. In 2008, for example, the Zimbabwean cholera outbreak was due partly to the government's role, according to a report from the James Baker Institute. The Haitian government's inability to provide safe drinking water after the 2010 earthquake led to an increase in cholera cases as well. Similarly, South Africa's cholera outbreak was exacerbated by the government's policy of privatizing water programs. The wealthy elite of the country were able to afford safe water while others had to use water from cholera-infected rivers. According to Rita R. Colwell of the James Baker Institute, if cholera does begin to spread, government preparedness is crucial. A government's ability to contain the disease before it extends to other areas can prevent a high death toll and the development of an epidemic or even pandemic. Effective disease surveillance can ensure that cholera outbreaks are recognized as soon as possible and dealt with appropriately. Oftentimes, this will allow public health programs to determine and control the cause of the cases, whether it is unsanitary water or seafood that have accumulated a lot of Vibrio cholerae specimens. Having an effective surveillance program contributes to a government's ability to prevent cholera from spreading. In the year 2000 in the state of Kerala in India, the Kottayam district was determined to be "Cholera-affected"; this pronouncement led to task forces that concentrated on educating citizens with 13,670 information sessions about human health. These task forces promoted the boiling of water to obtain safe water, and provided chlorine and oral rehydration salts. Ultimately, this helped to control the spread of the disease to other areas and minimize deaths. On the other hand, researchers have shown that most of the citizens infected during the 1991 cholera outbreak in Bangladesh lived in rural areas, and were not recognized by the government's surveillance program. This inhibited physicians' abilities to detect cholera cases early. According to Colwell, the quality and inclusiveness of a country's health care system affects the control of cholera, as it did in the Zimbabwean cholera outbreak. While sanitation practices are important, when governments respond quickly and have readily available vaccines, the country will have a lower cholera death toll. Affordability of vaccines can be a problem; if the governments do not provide vaccinations, only the wealthy may be able to afford them and there will be a greater toll on the country's poor. The speed with which government leaders respond to cholera outbreaks is important. Besides contributing to an effective or declining public health care system and water sanitation treatments, government can have indirect effects on cholera control and the effectiveness of a response to cholera. A country's government can impact its ability to prevent disease and control its spread. A speedy government response backed by a fully functioning health care system and financial resources can prevent cholera's spread. This limits cholera's ability to cause death, or at the very least a decline in education, as children are kept out of school to minimize the risk of infection. Notable cases Tchaikovsky's death has traditionally been attributed to cholera, most probably contracted through drinking contaminated water several days earlier. Tchaikovsky's mother died of cholera, and his father became sick with cholera at this time but made a full recovery. Some scholars, however, including English musicologist and Tchaikovsky authority David Brown and biographer Anthony Holden, have theorized that his death was a suicide. 2010s Haiti cholera outbreak. Ten months after the 2010 earthquake, an outbreak swept over Haiti, traced to a United Nations base of peacekeepers from Nepal. This marks the worst cholera outbreak in
is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure. Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked seafood is a common source. Humans are the only known host for the bacteria. Risk factors for the disease include poor sanitation, not enough clean drinking water, and poverty. Cholera can be diagnosed by a stool test. A rapid dipstick test is available but is not as accurate. Prevention methods against cholera include improved sanitation and access to clean water. Cholera vaccines that are given by mouth provide reasonable protection for about six months. They have the added benefit of protecting against another type of diarrhea caused by E. coli. The primary treatment is oral rehydration therapy—the replacement of fluids with slightly sweet and salty solutions. Rice-based solutions are preferred. Zinc supplementation is useful in children. In severe cases, intravenous fluids, such as Ringer's lactate, may be required, and antibiotics may be beneficial. Testing to see which antibiotic the cholera is susceptible to can help guide the choice. Cholera affects an estimated 3–5 million people worldwide and causes 28,800–130,000 deaths a year. Although it is classified as a pandemic , it is rare in high income countries. Children are mostly affected. Cholera occurs as both outbreaks and chronically in certain areas. Areas with an ongoing risk of disease include Africa and Southeast Asia. The risk of death among those affected is usually less than 5% but may be as high as 50%. No access to treatment results in a higher death rate. Descriptions of cholera are found as early as the 5th century BC in Sanskrit. The study of cholera in England by John Snow between 1849 and 1854 led to significant advances in the field of epidemiology. Seven large outbreaks have occurred over the last 200 years with millions of deaths. Signs and symptoms The primary symptoms of cholera are profuse diarrhea and vomiting of clear fluid. These symptoms usually start suddenly, half a day to five days after ingestion of the bacteria. The diarrhea is frequently described as "rice water" in nature and may have a fishy odor. An untreated person with cholera may produce of diarrhea a day. Severe cholera, without treatment, kills about half of affected individuals. If the severe diarrhea is not treated, it can result in life-threatening dehydration and electrolyte imbalances. Estimates of the ratio of asymptomatic to symptomatic infections have ranged from 3 to 100. Cholera has been nicknamed the "blue death" because a person's skin may turn bluish-gray from extreme loss of fluids. Fever is rare and should raise suspicion for secondary infection. Patients can be lethargic and might have sunken eyes, dry mouth, cold clammy skin, or wrinkled hands and feet. Kussmaul breathing, a deep and labored breathing pattern, can occur because of acidosis from stool bicarbonate losses and lactic acidosis associated with poor perfusion. Blood pressure drops due to dehydration, peripheral pulse is rapid and thready, and urine output decreases with time. Muscle cramping and weakness, altered consciousness, seizures, or even coma due to electrolyte imbalances are common, especially in children. Cause Transmission Cholera bacteria have been found in shellfish and plankton. Transmission is usually through the fecal-oral route of contaminated food or water caused by poor sanitation. Most cholera cases in developed countries are a result of transmission by food, while in developing countries it is more often water. Food transmission can occur when people harvest seafood such as oysters in waters infected with sewage, as Vibrio cholerae accumulates in planktonic crustaceans and the oysters eat the zooplankton. People infected with cholera often have diarrhea, and disease transmission may occur if this highly liquid stool, colloquially referred to as "rice-water", contaminates water used by others. A single diarrheal event can cause a one-million fold increase in numbers of V. cholerae in the environment. The source of the contamination is typically other cholera sufferers when their untreated diarrheal discharge is allowed to get into waterways, groundwater or drinking water supplies. Drinking any contaminated water and eating any foods washed in the water, as well as shellfish living in the affected waterway, can cause a person to contract an infection. Cholera is rarely spread directly from person to person. V. cholerae also exists outside the human body in natural water sources, either by itself or through interacting with phytoplankton, zooplankton, or biotic and abiotic detritus. Drinking such water can also result in the disease, even without prior contamination through fecal matter. Selective pressures exist however in the aquatic environment that may reduce the virulence of V. cholerae. Specifically, animal models indicate that the transcriptional profile of the pathogen changes as it prepares to enter an aquatic environment. This transcriptional change results in a loss of ability of V. cholerae to be cultured on standard media, a phenotype referred to as 'viable but non-culturable' (VBNC) or more conservatively 'active but non-culturable' (ABNC). One study indicates that the culturability of V. cholerae drops 90% within 24 hours of entering the water, and furthermore that this loss in culturability is associated with a loss in virulence. Both toxic and non-toxic strains exist. Non-toxic strains can acquire toxicity through a temperate bacteriophage. Susceptibility About 100million bacteria must typically be ingested to cause cholera in a normal healthy adult. This dose, however, is less in those with lowered gastric acidity (for instance those using proton pump inhibitors). Children are also more susceptible, with two- to four-year-olds having the highest rates of infection. Individuals' susceptibility to cholera is also affected by their blood type, with those with type O blood being the most susceptible. Persons with lowered immunity, such as persons with AIDS or malnourished children, are more likely to experience a severe case if they become infected. Any individual, even a healthy adult in middle age, can experience a severe case, and each person's case should be measured by the loss of fluids, preferably in consultation with a professional health care provider. The cystic fibrosis genetic mutation known as delta-F508 in humans has been said to maintain a selective heterozygous advantage: heterozygous carriers of the mutation (who are thus not affected by cystic fibrosis) are more resistant to V. cholerae infections. In this model, the genetic deficiency in the cystic fibrosis transmembrane conductance regulator channel proteins interferes with bacteria binding to the intestinal epithelium, thus reducing the effects of an infection. Mechanism When consumed, most bacteria do not survive the acidic conditions of the human stomach. The few surviving bacteria conserve their energy and stored nutrients during the passage through the stomach by shutting down protein production. When the surviving bacteria exit the stomach and reach the small intestine, they must propel themselves through the thick mucus that lines the small intestine to reach the intestinal walls where they can attach and thrive. Once the cholera bacteria reach the intestinal wall, they no longer need the flagella to move. The bacteria stop producing the protein flagellin to conserve energy and nutrients by changing the mix of proteins that they express in response to the changed chemical surroundings. On reaching the intestinal wall, V. cholerae start producing the toxic proteins that give the infected person a watery diarrhea. This carries the multiplying new generations of V. cholerae bacteria out into the drinking water of the next host if proper sanitation measures are not in place. The cholera toxin (CTX or CT) is an oligomeric complex made up of six protein subunits: a single copy of the A subunit (part A), and five copies of the B subunit (part B), connected by a disulfide bond. The five B subunits form a five-membered ring that binds to GM1 gangliosides on the surface of the intestinal epithelium cells. The A1 portion of the A subunit is an enzyme that ADP-ribosylates G proteins, while the A2 chain fits into the central pore of the B subunit ring. Upon binding, the complex is taken into the cell via receptor-mediated endocytosis. Once inside the cell, the disulfide bond is reduced, and the A1 subunit is freed to bind with a human partner protein called ADP-ribosylation factor 6 (Arf6). Binding exposes its active site, allowing it to permanently ribosylate the Gs alpha subunit of the heterotrimeric G protein. This results in constitutive cAMP production, which in turn leads to the secretion of water, sodium, potassium, and bicarbonate into the lumen of the small intestine and rapid dehydration. The gene encoding the cholera toxin was introduced into V. cholerae by horizontal gene transfer. Virulent strains of V. cholerae carry a variant of a temperate bacteriophage called CTXφ. Microbiologists have studied the genetic mechanisms by which the V. cholerae bacteria turn off the production of some proteins and turn on the production of other proteins as they respond to the series of chemical environments they encounter, passing through the stomach, through the mucous layer of the small intestine, and on to the intestinal wall. Of particular interest have been the genetic mechanisms by which cholera bacteria turn on the protein production of the toxins that interact with host cell mechanisms to pump chloride ions into the small intestine, creating an ionic pressure which prevents sodium ions from entering the cell. The chloride and sodium ions create a salt-water environment in the small intestines, which through osmosis can pull up to six liters of water per day through the intestinal cells, creating the massive amounts of diarrhea. The host can become rapidly dehydrated unless treated properly. By inserting separate, successive sections of V. cholerae DNA into the DNA of other bacteria, such as E. coli that would not naturally produce the protein toxins, researchers have investigated the mechanisms by which V. cholerae responds to the changing chemical environments of the stomach, mucous layers, and intestinal wall. Researchers have discovered a complex cascade of regulatory proteins controls expression of V. cholerae virulence determinants. In responding to the chemical environment at the intestinal wall, the V. cholerae bacteria produce the TcpP/TcpH proteins, which, together with the ToxR/ToxS proteins, activate the expression of the ToxT regulatory protein. ToxT then directly activates expression of virulence genes that produce the toxins, causing diarrhea in the infected person and allowing the bacteria to colonize the intestine. Current research aims at discovering "the signal that makes the cholera bacteria stop swimming and start to colonize (that is, adhere to the cells of) the small intestine." Genetic structure Amplified fragment length polymorphism fingerprinting of the pandemic isolates of V. cholerae has revealed variation in the genetic structure. Two clusters have been identified: Cluster I and Cluster II. For the most part, Cluster I consists of strains from the 1960s and 1970s, while Cluster II largely contains strains from the 1980s and 1990s, based on the change in the clone structure. This grouping of strains is best seen in the strains from the African continent. Antibiotic resistance In many areas of the world, antibiotic resistance is increasing within cholera bacteria. In Bangladesh, for example, most cases are resistant to tetracycline, trimethoprim-sulfamethoxazole, and erythromycin. Rapid diagnostic assay methods are available for the identification of multi-drug resistant cases. New generation antimicrobials have been discovered which are effective against cholera bacteria in in vitro studies. Diagnosis A rapid dipstick test is available to determine the presence of V. cholerae. In those samples that test positive, further testing should be done to determine antibiotic resistance. In epidemic situations, a clinical diagnosis may be made by taking a patient history and doing a brief examination. Treatment is usually started without or before confirmation by laboratory analysis. Stool and swab samples collected in the acute stage of the disease, before antibiotics have been administered, are the most useful specimens for laboratory diagnosis. If an epidemic of cholera is suspected, the most common causative agent is V. cholerae O1. If V. cholerae serogroup O1 is not isolated, the laboratory should test for V. cholerae O139. However, if neither of these organisms is isolated, it is necessary to send stool specimens to a reference laboratory. Infection with
unable to entrain enough air to remain buoyant, and the eruption column collapses into a tephra fountain that falls back to the surface to form pyroclastic flows. Eruptions of this type can spread ash over vast areas, so that ash flow tuffs emplaced by silicic caldera eruptions are the only volcanic product with volumes rivaling those of flood basalts. For example, when Yellowstone Caldera last erupted some 650,000 years ago, it released about 1,000 km3 of material (as measured in dense rock equivalent (DRE)), covering a substantial part of North America in up to two metres of debris. Eruptions forming even larger calderas are known, such as the La Garita Caldera in the San Juan Mountains of Colorado, where the Fish Canyon Tuff was blasted out in eruptions about 27.8 million years ago. The caldera produced by such eruptions is typically filled in with tuff, rhyolite, and other igneous rocks. The caldera is surrounded by an outflow sheet of ash flow tuff (also called an ash flow sheet). If magma continues to be injected into the collapsed magma chamber, the center of the caldera may be uplifted in the form of a resurgent dome such as is seen at the Valles Caldera, Lake Toba, the San Juan volcanic field, Cerro Galán, Yellowstone, and many other calderas. Because a silicic caldera may erupt hundreds or even thousands of cubic kilometers of material in a single event, it can cause catastrophic environmental effects. Even small caldera-forming eruptions, such as Krakatoa in 1883 or Mount Pinatubo in 1991, may result in significant local destruction and a noticeable drop in temperature around the world. Large calderas may have even greater effects. The ecological effects of the eruption of a large caldera can be seen in the record of the Lake Toba eruption in Indonesia. At some points in geological time, rhyolitic calderas have appeared in distinct clusters. The remnants of such clusters may be found in places such as the Eocene Rum Complex of Scotland, the San Juan Mountains of Colorado (formed during the Oligocene, Miocene, and Pliocene epochs) or the Saint Francois Mountain Range of Missouri (erupted during the Proterozoic eon). Valles For their 1968 paper that first introduced the concept of a resurgent caldera to geology, R.L. Smith and R.A. Bailey chose the Valles caldera as their model. Although the Valles caldera is not unusually large, it is relatively young (1.25 million years old) and unusually well preserved, and it remains one of the best studied examples of a resurgent caldera. The ash flow tuffs of the Valles caldera, such as the Bandelier Tuff, were among the first to be thoroughly characterized. Toba About 74,000 years ago, this Indonesian volcano released about dense-rock equivalent of ejecta. This was the largest known eruption during the ongoing Quaternary period (the last 2.6 million years) and the largest known explosive eruption during the last 25 million years. In the late 1990s, anthropologist Stanley Ambrose proposed that a volcanic winter induced by this eruption reduced the human population to about 2,000–20,000 individuals, resulting in a population bottleneck. More recently, Lynn Jorde and Henry Harpending proposed that the human species was reduced to approximately 5,000-10,000 people. There is no direct evidence, however, that either theory is correct, and there is no evidence for any other animal decline or extinction, even in environmentally sensitive species. There is evidence that human habitation continued in India after the eruption. Non-explosive calderas Some volcanoes, such as the large shield volcanoes Kīlauea and Mauna Loa on the island of Hawaii, form calderas in a different fashion. The magma feeding these volcanoes is basalt, which is silica poor. As a result, the magma is much less viscous than the magma of a rhyolitic volcano, and the magma chamber is drained by large lava flows rather than by explosive events. The resulting calderas are also known as subsidence calderas and can form more gradually than explosive calderas. For instance, the caldera atop Fernandina Island collapsed in 1968 when parts of the caldera floor dropped . Extraterrestrial calderas Since the early 1960s, it has been known that volcanism has occurred on other planets and moons in the Solar System. Through the use of crewed and uncrewed spacecraft, volcanism has been discovered on Venus, Mars, the Moon, and Io, a satellite of Jupiter. None of these worlds have plate tectonics, which contributes approximately 60% of the Earth's volcanic activity (the other 40% is attributed to hotspot volcanism). Caldera structure is similar on all of these planetary bodies, though the size varies considerably. The average caldera diameter on Venus is . The average caldera diameter on Io is close to , and the mode is ; Tvashtar Paterae is likely the largest caldera with a diameter of . The average caldera diameter on Mars is , smaller than Venus. Calderas on Earth are the smallest of all planetary bodies and vary from as a maximum. The Moon The Moon has an outer shell of low-density crystalline rock that is a few hundred kilometers thick, which formed due to a rapid creation. The craters of the Moon have been well preserved through time and were once thought to have been the result of extreme volcanic activity, but actually were formed by meteorites, nearly all of which took place in the first few hundred million years after the Moon formed. Around 500 million years afterward, the Moon's mantle was able to be extensively melted due to the decay of radioactive elements. Massive basaltic eruptions took place generally at the base of large impact craters. Also, eruptions may have taken place due to a magma reservoir at the base of the crust. This forms a dome, possibly the same morphology of a shield volcano where calderas universally are known to form. Although caldera-like structures are rare on the Moon, they are not completely absent. The Compton-Belkovich Volcanic Complex on the far side of the Moon is thought to be a caldera, possibly an ash-flow caldera. Mars The volcanic activity of Mars is concentrated in two major provinces: Tharsis and Elysium. Each province contains a series of giant shield volcanoes that are similar to what we see on Earth and likely are the result of mantle hot spots. The surfaces are dominated by lava flows, and all have one or more collapse calderas. Mars has the largest volcano in the Solar System, Olympus Mons, which is more than three times the height of Mount Everest, with a diameter of 520 km (323 miles). The summit of the mountain has six nested calderas. Venus Because there is no plate tectonics on Venus, heat is mainly lost by conduction through the lithosphere. This causes enormous lava flows, accounting for 80% of Venus' surface area. Many of the mountains are large shield volcanoes that range in size from in diameter and high. More than 80 of these large shield volcanoes have summit calderas averaging across. Io Io, unusually, is heated by solid flexing due to the tidal influence of Jupiter and Io's orbital resonance with neighboring large moons Europa and Ganymede, which keep its orbit slightly eccentric. Unlike any of the planets mentioned, Io is continuously volcanically active. For example, the NASA

The writing on it was in Roman script, and it was exported to western countries.<ref>ELKA 100 series (photos) , (photo) , Clockwiser. Retrieved Oct 2013.</ref> Programmable calculators The first desktop programmable calculators were produced in the mid-1960s. They included the Mathatronics Mathatron (1964) and the Olivetti Programma 101 (late 1965) which were solid-state, desktop, printing, floating point, algebraic entry, programmable, stored-program electronic calculators. Both could be programmed by the end user and print out their results. The Programma 101 saw much wider distribution and had the added feature of offline storage of programs via magnetic cards. Another early programmable desktop calculator (and maybe the first Japanese one) was the Casio (AL-1000) produced in 1967. It featured a nixie tubes display and had transistor electronics and ferrite core memory. The Monroe Epic programmable calculator came on the market in 1967. A large, printing, desk-top unit, with an attached floor-standing logic tower, it could be programmed to perform many computer-like functions. However, the only branch instruction was an implied unconditional branch (GOTO) at the end of the operation stack, returning the program to its starting instruction. Thus, it was not possible to include any conditional branch (IF-THEN-ELSE) logic. During this era, the absence of the conditional branch was sometimes used to distinguish a programmable calculator from a computer. The first Soviet programmable desktop calculator ISKRA 123, powered by the power grid, was released at the start of the 1970s. 1970s to mid-1980s The electronic calculators of the mid-1960s were large and heavy desktop machines due to their use of hundreds of transistors on several circuit boards with a large power consumption that required an AC power supply. There were great efforts to put the logic required for a calculator into fewer and fewer integrated circuits (chips) and calculator electronics was one of the leading edges of semiconductor development. U.S. semiconductor manufacturers led the world in large scale integration (LSI) semiconductor development, squeezing more and more functions into individual integrated circuits. This led to alliances between Japanese calculator manufacturers and U.S. semiconductor companies: Canon Inc. with Texas Instruments, Hayakawa Electric (later renamed Sharp Corporation) with North-American Rockwell Microelectronics (later renamed Rockwell International), Busicom with Mostek and Intel, and General Instrument with Sanyo. Pocket calculators By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add, multiply, subtract, and divide, and its output device was a paper tape.Electronic Calculator Invented 40 Years Ago All Things Considered, NPR, 30 September 2007. Audio interview with one of the inventors. As a result of the "Cal-Tech" project, Texas Instruments was granted master patents on portable calculators. The first commercially produced portable calculators appeared in Japan in 1970, and were soon marketed around the world. These included the Sanyo ICC-0081 "Mini Calculator", the Canon Pocketronic, and the Sharp QT-8B "micro Compet". The Canon Pocketronic was a development from the "Cal-Tech" project. It had no traditional display; numerical output was on thermal paper tape. Sharp put in great efforts in size and power reduction and introduced in January 1971 the Sharp EL-8, also marketed as the Facit 1111, which was close to being a pocket calculator. It weighed 1.59 pounds (721 grams), had a vacuum fluorescent display, rechargeable NiCad batteries, and initially sold for US $395. However, integrated circuit development efforts culminated in early 1971 with the introduction of the first "calculator on a chip", the MK6010 by Mostek, followed by Texas Instruments later in the year. Although these early hand-held calculators were very costly, these advances in electronics, together with developments in display technology (such as the vacuum fluorescent display, LED, and LCD), led within a few years to the cheap pocket calculator available to all. In 1971, Pico Electronics and General Instrument also introduced their first collaboration in ICs, a full single chip calculator IC for the Monroe Royal Digital III calculator. Pico was a spinout by five GI design engineers whose vision was to create single chip calculator ICs. Pico and GI went on to have significant success in the burgeoning handheld calculator market. The first truly pocket-sized electronic calculator was the Busicom LE-120A "HANDY", which was marketed early in 1971. Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures . The first European-made pocket-sized calculator, DB 800 was made in May 1971 by Digitron in Buje, Croatia (former Yugoslavia) with four functions and an eight-digit display and special characters for a negative number and a warning that the calculation has too many digits to display. The first American-made pocket-sized calculator, the Bowmar 901B (popularly termed The Bowmar Brain), measuring , came out in the Autumn of 1971, with four functions and an eight-digit red LED display, for $240, while in August 1972 the four-function Sinclair Executive became the first slimline pocket calculator measuring and weighing . It retailed for around £79 ($194 at the time). By the end of the decade, similar calculators were priced less than £5 ($). Following protracted development over the course of two years including a botched partnership with Texas Instruments, Eldorado Electrodata released five pocket calculators in 1972. One called the Touch Magic was "no bigger than a pack of cigarettes" according to Administrative Management. The first Soviet Union made pocket-sized calculator, the Elektronika B3-04 was developed by the end of 1973 and sold at the start of 1974. One of the first low-cost calculators was the Sinclair Cambridge, launched in August 1973. It retailed for £29.95 ($), or £5 ($) less in kit form. The Sinclair calculators were successful because they were far cheaper than the competition; however, their design led to slow and inaccurate computations of transcendental functions. Meanwhile, Hewlett-Packard (HP) had been developing a pocket calculator. Launched in early 1972, it was unlike the other basic four-function pocket calculators then available in that it was the first pocket calculator with scientific functions that could replace a slide rule. The $395 HP-35, along with nearly all later HP engineering calculators, uses reverse Polish notation (RPN), also called postfix notation. A calculation like "8 plus 5" is, using RPN, performed by pressing , , , and ; instead of the algebraic infix notation: , , , . It had 35 buttons and was based on Mostek Mk6020 chip. The first Soviet scientific pocket-sized calculator the "B3-18" was completed by the end of 1975. In 1973, Texas Instruments (TI) introduced the SR-10, (SR signifying slide rule) an algebraic entry pocket calculator using scientific notation for $150. Shortly after the SR-11 featured an added key for entering pi (π). It was followed the next year by the SR-50 which added log and trig functions to compete with the HP-35, and in 1977 the mass-marketed TI-30 line which is still produced. In 1978, a new company, Calculated Industries arose which focused on specialized markets. Their first calculator, the Loan Arranger (1978) was a pocket calculator marketed to the Real Estate industry with preprogrammed functions to simplify the process of calculating payments and future values. In 1985, CI launched a calculator for the construction industry called the Construction Master which came preprogrammed with common construction calculations (such as angles, stairs, roofing math, pitch, rise, run, and feet-inch fraction conversions). This would be the first in a line of construction related calculators. Programmable pocket calculators The first programmable pocket calculator was the HP-65, in 1974; it had a capacity of 100 instructions, and could store and retrieve programs with a built-in magnetic card reader. Two years later the HP-25C introduced continuous memory, i.e., programs and data were retained in CMOS memory during power-off. In 1979, HP released the first alphanumeric, programmable, expandable calculator, the HP-41C. It could be expanded with random-access memory (RAM, for memory) and read-only memory (ROM, for software) modules, and peripherals like bar code readers, microcassette and floppy disk drives, paper-roll thermal printers, and miscellaneous communication interfaces (RS-232, HP-IL, HP-IB). The first Soviet pocket battery-powered programmable calculator, Elektronika B3-21, was developed by the end of 1976 and released at the start of 1977. The successor of B3-21, the Elektronika B3-34 wasn't backward compatible with B3-21, even if it kept the reverse Polish notation (RPN). Thus B3-34 defined a new command set, which later was used in a series of later programmable Soviet calculators. Despite very limited abilities (98 bytes of instruction memory and about 19 stack and addressable registers), people managed to write all kinds of programs for them, including adventure games and libraries of calculus-related functions for engineers. Hundreds, perhaps thousands, of programs were written for these machines, from practical scientific and business software, which were used in real-life offices and labs, to fun games for children. The Elektronika MK-52 calculator (using the extended B3-34 command set, and featuring internal EEPROM memory for storing programs and external interface for EEPROM cards and other periphery) was used in Soviet spacecraft

Hundreds, perhaps thousands, of programs were written for these machines, from practical scientific and business software, which were used in real-life offices and labs, to fun games for children. The Elektronika MK-52 calculator (using the extended B3-34 command set, and featuring internal EEPROM memory for storing programs and external interface for EEPROM cards and other periphery) was used in Soviet spacecraft program (for Soyuz TM-7 flight) as a backup of the board computer. This series of calculators was also noted for a large number of highly counter-intuitive mysterious undocumented features, somewhat similar to "synthetic programming" of the American HP-41, which were exploited by applying normal arithmetic operations to error messages, jumping to nonexistent addresses and other methods. A number of respected monthly publications, including the popular science magazine Nauka i Zhizn (Наука и жизнь, Science and Life), featured special columns, dedicated to optimization methods for calculator programmers and updates on undocumented features for hackers, which grew into a whole esoteric science with many branches, named "yeggogology" ("еггогология"). The error messages on those calculators appear as a Russian word "YEGGOG" ("ЕГГОГ") which, unsurprisingly, is translated to "Error". A similar hacker culture in the USA revolved around the HP-41, which was also noted for a large number of undocumented features and was much more powerful than B3-34. Technical improvements Through the 1970s the hand-held electronic calculator underwent rapid development. The red LED and blue/green vacuum fluorescent displays consumed a lot of power and the calculators either had a short battery life (often measured in hours, so rechargeable nickel-cadmium batteries were common) or were large so that they could take larger, higher capacity batteries. In the early 1970s liquid-crystal displays (LCDs) were in their infancy and there was a great deal of concern that they only had a short operating lifetime. Busicom introduced the Busicom LE-120A "HANDY" calculator, the first pocket-sized calculator and the first with an LED display, and announced the Busicom LC with LCD. However, there were problems with this display and the calculator never went on sale. The first successful calculators with LCDs were manufactured by Rockwell International and sold from 1972 by other companies under such names as: Dataking LC-800, Harden DT/12, Ibico 086, Lloyds 40, Lloyds 100, Prismatic 500 (a.k.a. P500), Rapid Data Rapidman 1208LC. The LCDs were an early form using the Dynamic Scattering Mode DSM with the numbers appearing as bright against a dark background. To present a high-contrast display these models illuminated the LCD using a filament lamp and solid plastic light guide, which negated the low power consumption of the display. These models appear to have been sold only for a year or two. A more successful series of calculators using a reflective DSM-LCD was launched in 1972 by Sharp Inc with the Sharp EL-805, which was a slim pocket calculator. This, and another few similar models, used Sharp's Calculator On Substrate (COS) technology. An extension of one glass plate needed for the liquid crystal display was used as a substrate to mount the needed chips based on a new hybrid technology. The COS technology may have been too costly since it was only used in a few models before Sharp reverted to conventional circuit boards. In the mid-1970s the first calculators appeared with field-effect, twisted nematic (TN) LCDs with dark numerals against a grey background, though the early ones often had a yellow filter over them to cut out damaging ultraviolet rays. The advantage of LCDs is that they are passive light modulators reflecting light, which require much less power than light-emitting displays such as LEDs or VFDs. This led the way to the first credit-card-sized calculators, such as the Casio Mini Card LC-78 of 1978, which could run for months of normal use on button cells. There were also improvements to the electronics inside the calculators. All of the logic functions of a calculator had been squeezed into the first "calculator on a chip" integrated circuits (ICs) in 1971, but this was leading edge technology of the time and yields were low and costs were high. Many calculators continued to use two or more ICs, especially the scientific and the programmable ones, into the late 1970s. The power consumption of the integrated circuits was also reduced, especially with the introduction of CMOS technology. Appearing in the Sharp "EL-801" in 1972, the transistors in the logic cells of CMOS ICs only used any appreciable power when they changed state. The LED and VFD displays often required added driver transistors or ICs, whereas the LCDs were more amenable to being driven directly by the calculator IC itself. With this low power consumption came the possibility of using solar cells as the power source, realised around 1978 by calculators such as the Royal Solar 1, Sharp EL-8026, and Teal Photon. Mass-market phase At the start of the 1970s, hand-held electronic calculators were very costly, at two or three weeks' wages, and so were a luxury item. The high price was due to their construction requiring many mechanical and electronic components which were costly to produce, and production runs that were too small to exploit economies of scale. Many firms saw that there were good profits to be made in the calculator business with the margin on such high prices. However, the cost of calculators fell as components and their production methods improved, and the effect of economies of scale was felt. By 1976, the cost of the cheapest four-function pocket calculator had dropped to a few dollars, about 1/20 of the cost five years before. The results of this were that the pocket calculator was affordable, and that it was now difficult for the manufacturers to make a profit from calculators, leading to many firms dropping out of the business or closing. The firms that survived making calculators tended to be those with high outputs of higher quality calculators, or producing high-specification scientific and programmable calculators. Mid-1980s to present The first calculator capable of symbolic computing was the HP-28C, released in 1987. It could, for example, solve quadratic equations symbolically. The first graphing calculator was the Casio fx-7000G released in 1985. The two leading manufacturers, HP and TI, released increasingly feature-laden calculators during the 1980s and 1990s. At the turn of the millennium, the line between a graphing calculator and a handheld computer was not always clear, as some very advanced calculators such as the TI-89, the Voyage 200 and HP-49G could differentiate and integrate functions, solve differential equations, run word processing and PIM software, and connect by wire or IR to other calculators/computers. The HP 12c financial calculator is still produced. It was introduced in 1981 and is still being made with few changes. The HP 12c featured the reverse Polish notation mode of data entry. In 2003 several new models were released, including an improved version of the HP 12c, the "HP 12c platinum edition" which added more memory, more built-in functions, and the addition of the algebraic mode of data entry. Calculated Industries competed with the HP 12c in the mortgage and real estate markets by differentiating the key labeling; changing the “I”, “PV”, “FV” to easier labeling terms such as "Int", "Term", "Pmt", and not using the reverse Polish notation. However, CI's more successful calculators involved a line of construction calculators, which evolved and expanded in the 1990s to present. According to Mark Bollman, a mathematics and calculator historian and associate professor of mathematics at Albion College, the "Construction Master is the first in a long and profitable line of CI construction calculators" which carried them through the 1980s, 1990s, and to the present. Personal computers often come with a calculator utility program that emulates the appearance and functions of a calculator, using the graphical user interface to portray a calculator. One such example is Windows Calculator. Most personal data assistants (PDAs) and smartphones also
the manual release in favor of a cylinder lock, requiring a key to manually open the drawer. The cylinder lock usually has several positions: locked, unlocked, online (will open if an impulse is given), and release. The release position is an intermittent position with a spring to push the cylinder back to the unlocked position. In the "locked" position, the drawer will remain latched even when an electric impulse is sent to the solenoid. Some cash drawers are designed to store notes upright & facing forward, instead of the traditional flat and front to back position position. This allows more varieties of notes to be stored. Some cash drawers are flip top in design, where they flip open instead of sliding out like an ordinary drawer, resembling a cashbox instead. Management functions An often used non-sale function is the aforementioned "no sale". In case of needing to correct change given to the customer, or to make change from a neighboring register, this function will open the cash drawer of the register. Where non-management staff are given access, management can scrutinize the count of "no sales" in the log to look for suspicious patterns. Generally requiring a management key, besides programming prices into the register, are the report functions. An "X" report will read the current sales figures from memory and produce a paper printout. A "Z" report will act like an "X" report, except that counters will be reset to zero. Manual input Registers will typically feature a numerical pad, QWERTY or custom keyboard, touch screen interface, or a combination of these input methods for the cashier to enter products and fees by hand and access information necessary to complete the sale. For older registers as well as at restaurants and other establishments that do not sell barcoded items, the manual input may be the only method of interacting with the register. While customization was previously limited to larger chains that could afford to have physical keyboards custom-built for their needs, the customization of register inputs is now more widespread with the use of touch screens that can display a variety of point of sale software. Scanner Modern cash registers may be connected to a handheld or stationary barcode reader so that a customer's purchases can be more rapidly scanned than would be possible by keying numbers into the register by hand. The use of scanners should also help prevent errors that result from manually entering the product's barcode or pricing. At grocers, the register's scanner may be combined with a scale for measuring product that is sold by weight. Receipt printer Cashiers are often required to provide a receipt to the customer after a purchase has been made. Registers typically use thermal printers to print receipts, although older dot matrix printers are still in use at some retailers. Alternatively, retailers can forgo issuing paper receipts in some jurisdictions by instead asking the customer for an email to which their receipt can be sent. The receipts of larger retailers tend to include unique barcodes or other information identifying the transaction so that the receipt can be scanned to facilitate returns or other customer services. Security deactivation In stores that use electronic article surveillance, a pad or other surface will be attached to the register that deactivates security devices embedded in or attached to the items being purchased. This will prevent a customer's purchase from setting off security alarms at the store's exit. Self-service cash register Some corporations and supermarkets have introduced self-checkout machines, where the customer is trusted to scan the barcodes (or manually identify uncoded items like fruit), and place the items into a bagging area. The bag is weighed, and the machine halts the checkout when the weight of something in the bag does not match the weight in the inventory database. Normally, an employee is watching over several such checkouts to prevent theft or exploitation of the machines' weaknesses (for example, intentional misidentification of expensive produce or dry goods). Payment on these machines is accepted by debit card/credit card, or cash via coin slot and bank note scanner. Store employees are also needed to authorize "age-restricted" purchases, such as alcohol,
sends an electrical impulse to a solenoid to release the catch and open the drawer. Cash drawers that are integral to a stand-alone register often have a manual release catch underneath to open the drawer in the event of a power failure. More advanced cash drawers have eliminated the manual release in favor of a cylinder lock, requiring a key to manually open the drawer. The cylinder lock usually has several positions: locked, unlocked, online (will open if an impulse is given), and release. The release position is an intermittent position with a spring to push the cylinder back to the unlocked position. In the "locked" position, the drawer will remain latched even when an electric impulse is sent to the solenoid.

cache, multiple CPUs or other components), improving performance and reducing overall system cost. As with most complex electronic designs, the logic verification effort (proving that the design does not have bugs) now dominates the project schedule of a CPU. Key CPU architectural innovations include index register, cache, virtual memory, instruction pipelining, superscalar, CISC, RISC, virtual machine, emulators, microprogram, and stack. Micro-architectural concepts Research topics A variety of new CPU design ideas have been proposed, including reconfigurable logic, clockless CPUs, computational RAM, and optical computing. Performance analysis and benchmarking Benchmarking is a way of testing CPU speed. Examples include SPECint and SPECfp, developed by Standard Performance Evaluation Corporation, and ConsumerMark developed by the Embedded Microprocessor Benchmark Consortium EEMBC. Some of the commonly used metrics include: Instructions per second - Most consumers pick a computer architecture (normally Intel IA32 architecture) to be able to run a large base of pre-existing pre-compiled software. Being relatively uninformed on computer benchmarks, some of them pick a particular CPU based on operating frequency (see Megahertz Myth). FLOPS - The number of floating point operations per second is often important in selecting computers for scientific computations. Performance per watt - System designers building parallel computers, such as Google, pick CPUs based on their speed per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. Some system designers building parallel computers pick CPUs based on the speed per dollar. System designers building real-time computing systems want to guarantee worst-case response. That is easier to do when the CPU has low interrupt latency and when it has deterministic response. (DSP) Computer programmers who program directly in assembly language want a CPU to support a full featured instruction set. Low power - For systems with limited power sources (e.g. solar, batteries, human power). Small size or low weight - for portable embedded systems, systems for spacecraft. Environmental impact - Minimizing environmental impact of computers during manufacturing and recycling as well during use. Reducing waste, reducing hazardous materials. (see Green computing). There may be tradeoffs in optimizing some of these metrics. In particular, many design techniques that make a CPU run faster make the "performance per watt", "performance per dollar", and "deterministic response" much worse, and vice versa. Markets There are several different markets in which CPUs are used. Since each of these markets differ in their requirements for CPUs, the devices designed for one market are in most cases inappropriate for the other markets. General purpose computing The vast majority of revenues generated from CPU sales is for general purpose computing, that is, desktop, laptop, and server computers commonly used in businesses and homes. In this market, the Intel IA-32 and the 64-bit version x86-64 architecture dominate the market, with its rivals PowerPC and SPARC maintaining much smaller customer bases. Yearly, hundreds of millions of IA-32 architecture CPUs are used by this market. A growing percentage of these processors are for mobile implementations such as netbooks and laptops. Since these devices are used to run countless different types of programs, these CPU designs are not specifically targeted at one type of application or one function. The demands of being able to run a wide range of programs efficiently has made these CPU designs among the more advanced technically, along with some disadvantages of being relatively costly, and having high power consumption. High-end processor economics In 1984, most high-performance CPUs required four to five years to develop. Scientific computing Scientific computing is a much smaller niche market (in revenue and units shipped). It is used in government research labs and universities. Before 1990, CPU design was often done for this market, but mass market CPUs organized into large clusters have proven to be more affordable. The main remaining area of active hardware design and research for scientific computing is for high-speed data transmission systems to connect mass market CPUs. Embedded design As measured by units shipped, most CPUs are embedded in other machinery, such as telephones, clocks, appliances, vehicles, and infrastructure. Embedded processors sell in the volume of many billions of units per year, however, mostly at much lower price points than that of the general purpose processors. These single-function devices differ from the more familiar general-purpose CPUs in several ways: Low cost is of high importance. It is important to maintain a low power dissipation as embedded devices often have a limited battery life and it is often impractical to include cooling fans. To give lower system cost, peripherals are integrated with the processor on the same silicon chip. Keeping peripherals on-chip also reduces power consumption as external GPIO ports typically require buffering so that they can source or sink the relatively high current loads that are required to maintain a strong signal outside of the chip. Many embedded applications have a limited amount of physical space for circuitry; keeping peripherals on-chip will reduce the space required for the circuit board. The program and data memories are often integrated on the same chip. When the only allowed program memory is ROM, the device is known as a microcontroller. For many embedded applications, interrupt latency will be more critical than in some general-purpose processors. Embedded processor economics The embedded CPU family with the largest number of total units shipped is the 8051, averaging nearly a billion units per year. The 8051 is widely used because it is very inexpensive. The design time is now roughly zero, because it is widely available as commercial intellectual property. It is now often embedded as a small part of a larger system on a chip. The silicon cost of an 8051 is now as low as US$0.001, because
read/write memory, perform relational tests between data values and to control program flow. Processor designs are often tested and validated on one or several FPGAs before sending the design of the processor to a foundry for semiconductor fabrication. Details Basics CPU design is divided into design of the following components: Datapaths (such as ALUs and pipelines) Control unit: logic which controls the datapaths Memory components such as register files, caches Clock circuitry such as clock drivers, PLLs, clock distribution networks Pad transceiver circuitry Logic gate cell library which is used to implement the logic CPUs designed for high-performance markets might require custom (optimized or application specific (see below)) designs for each of these items to achieve frequency, power-dissipation, and chip-area goals whereas CPUs designed for lower performance markets might lessen the implementation burden by acquiring some of these items by purchasing them as intellectual property. Control logic implementation techniques (logic synthesis using CAD tools) can be used to implement datapaths, register files, and clocks. Common logic styles used in CPU design include unstructured random logic, finite-state machines, microprogramming (common from 1965 to 1985), and Programmable logic arrays (common in the 1980s, no longer common). Implementation logic Device types used to implement the logic include: Transistor-transistor logic Small Scale Integration logic chips - no longer used for CPUs Programmable Array Logic and Programmable logic devices - no longer used for CPUs Emitter-coupled logic (ECL) gate arrays - no longer common CMOS gate arrays - no longer used for CPUs CMOS mass-produced ICs - the vast majority of CPUs by volume CMOS ASICs - only for a minority of special applications due to expense Field-programmable gate arrays (FPGA) - common for soft microprocessors, and more or less required for reconfigurable computing A CPU design project generally has these major tasks: Programmer-visible instruction set architecture, which can be implemented by a variety of microarchitectures Architectural study and performance modeling in ANSI C/C++ or SystemC High-level synthesis (HLS) or register transfer level (RTL, e.g. logic) implementation RTL verification Circuit design of speed critical components (caches, registers, ALUs) Logic synthesis or logic-gate-level design Timing analysis to confirm that all logic and circuits will run at the specified operating frequency Physical design including floorplanning, place and route of logic gates Checking that RTL, gate-level, transistor-level and physical-level representations are equivalent Checks for signal integrity, chip manufacturability Re-designing a CPU core to a smaller die-area helps to shrink everything (a "photomask shrink"), resulting in the same number of transistors on a smaller die. It improves performance (smaller transistors switch faster), reduces power (smaller wires have less parasitic capacitance) and reduces cost (more CPUs fit on the same wafer of silicon). Releasing a CPU on the same size die, but with a smaller CPU core, keeps the cost about the same but allows higher levels of integration within one very-large-scale integration chip (additional cache, multiple CPUs or other components), improving performance and reducing overall system cost. As with most complex electronic designs, the logic verification effort (proving that the design does not have bugs) now dominates the project schedule of a CPU. Key CPU architectural innovations include index register, cache, virtual memory, instruction pipelining, superscalar, CISC, RISC, virtual machine, emulators, microprogram, and stack. Micro-architectural concepts Research topics A variety of new CPU design ideas have been proposed, including reconfigurable logic, clockless CPUs, computational RAM, and optical computing. Performance analysis and benchmarking Benchmarking is a way of testing CPU speed. Examples include SPECint and SPECfp, developed by Standard Performance Evaluation Corporation, and ConsumerMark developed by the Embedded Microprocessor Benchmark Consortium EEMBC. Some of the commonly used metrics include: Instructions per second - Most consumers pick a computer architecture (normally Intel IA32 architecture) to be able to run a large base of pre-existing pre-compiled software. Being relatively uninformed on computer benchmarks, some of them pick a particular CPU based on operating frequency (see Megahertz Myth). FLOPS - The number of floating point operations per second is often important in selecting computers for scientific computations. Performance per watt - System designers building parallel computers, such as Google, pick CPUs based on their speed per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself.

of the sternum). The difficulty with this scheme phylogenetically was that some flightless birds, without strong keels, are descended directly from ordinary flying birds possessing one. Examples include the kakapo, a flightless parrot, and the dodo, a columbiform (the pigeon family). Neither of these birds are a ratite. Thus, this supposedly distinctive feature was easy to use, but had nothing to do with actual phylogenetic relationship. Beginning in the 1980s, Carinatae was given several phylogenetic definitions. The first was as a node-based clade uniting Ichthyornis with modern birds. However, in many analyses,
use, but had nothing to do with actual phylogenetic relationship. Beginning in the 1980s, Carinatae was given several phylogenetic definitions. The first was as a node-based clade uniting Ichthyornis with modern birds. However, in many analyses, this definition would be synonymous with the more widely used name Ornithurae. An alternate definition was provided in 2001, naming Carinatae an apomorphy-based clade defined by the presence of a keeled sternum. The most primitive known bird relative with a keeled breastbone is Confuciusornis. While some specimens of this stem-bird have flat breastbones, some show a
in The Balance and Columbian Repository (Hudson, New York) May 13, 1806; editor Harry Croswell answered the question, "What is a cocktail?": Dale DeGroff hypothesizes that the word evolved from the French coquetier, for an eggcup in which Antoine A. Peychaud, creator of Peychaud's Bitters, allegedly used to serve his guests a mix of cognac with a dash of his bitters. Etymologist Anatoly Liberman endorses as "highly probable" the theory advanced by Låftman (1946), which Liberman summarizes as follows: In his book Imbibe! (2007), cocktail historian David Wondrich also speculates that cocktail is a reference to gingering, a practice for perking up an old horse by means of a ginger suppository so that the animal would "cock its tail up and be frisky." Several authors have theorized that cocktail may be a corruption of cock ale. Development There is a lack of clarity on the origins of cocktails. Traditionally cocktails were a mixture of spirits, sugar, water, and bitters. By the 1860s, however, a cocktail frequently included a liqueur. The first publication of a bartenders' guide which included cocktail recipes was in 1862 – How to Mix Drinks; or, The Bon Vivant's Companion, by "Professor" Jerry Thomas. In addition to recipes for punches, sours, slings, cobblers, shrubs, toddies, flips, and a variety of other mixed drinks were 10 recipes for "cocktails". A key ingredient differentiating cocktails from other drinks in this compendium was the use of bitters. Mixed drinks popular today that conform to this original meaning of "cocktail" include the Old Fashioned whiskey cocktail, the Sazerac cocktail, and the Manhattan cocktail. The ingredients listed (spirits, sugar, water, and bitters) match the ingredients of an Old Fashioned, which originated as a term used by late 19th century bar patrons to distinguish cocktails made the "old-fashioned" way from newer, more complex cocktails. In the 1869 recipe book Cooling Cups and Dainty Drinks, by William Terrington, cocktails are described as: The term highball appears during the 1890s to distinguish a drink composed only of a distilled spirit and a mixer. Published in 1902 by Farrow and Jackson, "Recipes of American and Other Iced Drinks" contains recipes for nearly two dozen cocktails, some still recognizable today. The first "cocktail party" ever thrown was allegedly by Mrs. Julius S. Walsh Jr. of St. Louis, Missouri, in May 1917. Walsh invited 50 guests to her home at noon on a Sunday. The party lasted an hour, until lunch was served at 1 pm. The site of this first cocktail party still stands. In 1924, the Roman Catholic Archdiocese of St. Louis bought the Walsh mansion at 4510 Lindell Boulevard, and it has served as the local archbishop's residence ever since. During Prohibition in the United States (1920–1933), when alcoholic beverages were illegal, cocktails were still consumed illegally in establishments known as speakeasies. The quality of the liquor available during Prohibition was much worse than previously. There was a shift from whiskey to gin, which does not require aging and is therefore easier to produce illicitly. Honey, fruit juices, and other flavorings served to mask the foul taste of the inferior liquors. Sweet cocktails were easier to drink quickly, an important consideration when the establishment might be raided at any moment. With wine and beer less readily available, liquor-based cocktails took their place, even becoming the centerpiece of the new cocktail party. Cocktails became less popular in the late 1960s and through the 1970s, until resurging in the 1980s with vodka often substituting for the original gin in drinks such as the martini. Traditional cocktails began to make a comeback in the 2000s, and by the mid-2000s there was a renaissance of cocktail culture in a style typically referred to as mixology that draws on traditional cocktails for inspiration but utilizes novel ingredients and often complex flavors.

Orthodox Pope, Pope Shenouda III died, leaving many Copts mourning and worrying as tensions rose with Muslims. Pope Shenouda III constantly met with Muslim leaders in order to create peace. Many were worried about Muslims controlling Egypt as the Muslim Brotherhood won 70% of the parliamentary elections. On 4 November 2012, Bishop Tawadros was chosen as the 118th Pope. In a ritual filled with prayer, chants and incense at Abbasiya cathedral in Cairo, the 60-year-old bishop's name was picked by a blindfolded child from a glass bowl in which the names of two other candidates had also been placed. The enthronement was scheduled on 18 November 2012. Fasting, liturgy and canonical hours According to Christian tradition and Canon Law, the Coptic Orthodox Church only ordains men to the priesthood and episcopate, and if they wish to be married, they must be married before they are ordained. In this respect, they follow the same practices as all other Oriental Orthodox Churches, as well as all of the Eastern Orthodox Church. Traditionally, the Coptic language was used in church services, and the scriptures were written in the Coptic alphabet. However, due to the Arabisation of Egypt, service in churches started to witness increased use of Arabic, while preaching is done entirely in Arabic. Local vernacular languages are used, in conjunction with Arabic and/or Coptic, during services outside Egypt. The liturgical calendar of the Coptic Orthodox Church is the Coptic calendar (also called the Alexandrian Calendar). This calendar is based on the Egyptian calendar of Ancient Egypt. Coptic Orthodox Christians celebrate Christmas on 29 Koiak, which corresponds to 7 January in the Gregorian Calendar and 25 December in the Julian Calendar. Coptic Christmas was adopted as an official national holiday in Egypt in 2002. Communicants of the Coptic Orthodox Church use a breviary known as the Agpeya to pray the canonical hours at seven fixed prayer times while facing in the eastward direction, in anticipation of the Second Coming of Jesus; this Christian practice has its roots in Psalm 119:164, in which the prophet David prays to God seven times a day. Church bells enjoin Christians to pray at these hours. Before praying, they wash their hands and face in order to be clean before and present their best to God; shoes are removed in order to acknowledge that one is offering prayer before a holy God. During each of the seven fixed prayer times, Coptic Orthodox Christians pray "prostrating three times in the name of the Trinity; at the end of each Psalm … while saying the 'Alleluia';" and forty-one times for each of the Kyrie eleisons present in a canonical hour. In the Coptic Orthodox Church, it is customary for women to wear a Christian headcovering when praying. All churches of the Coptic Orthodox Church are designed to face the eastward direction of prayer and efforts are made to remodel churches obtained from other Christian denominations that are not built in this fashion. With respect to Eucharistic discipline, Coptic Orthodox Christians fast from midnight onwards before receiving the sacrament of Holy Communion. They fast every Wednesday and Friday of the year (Wednesdays in remembrance of the betrayal of Christ, and on Fridays, in remembrance of His crucifixion and death). In total, the number of fast days in a year for Coptic Orthodox Christians numbers around 240, with the fasts for Advent and Lent being forty-three days and fifty-five days, respectively. In August, before the celebration of the Dormition of the Mother of God, Coptic Christians fast fifteen days; fasting is also done before the feast of Feast of Saints Peter and Paul, starting from the day of Pentecost. Demographics Available Egyptian census figures and other third party survey reports have not reported more than 4 million Coptic Orthodox Christians in Egypt. However media and other agencies, sometimes taking into account the claims of the Church itself, generally approximate the Coptic Orthodox population at 10% of the Egyptian population or 10 million people. The majority of them live in Egypt under the jurisdiction of the Coptic Orthodox Church. Since 2006, Egyptian censuses have not reported on religion and church leaders have alleged that Christians were under-counted in government surveys. In 2017, a government owned newspaper Al Ahram estimated the percentage of Copts at 10 to 15% and the membership claimed by the Coptic Orthodox Church is in the range of 20 to 25 million. There are also significant numbers in the diaspora outside Africa in countries such as the United States, Canada, Australia, France, and Germany. The exact number of Egyptian born Coptic Orthodox Christians in the diaspora is hard to determine and is roughly estimated to be close to 1 million. There are between 150,000 and 200,000 adherents in Sudan. Persecution While Copts have cited instances of persecution throughout their history, Human Rights Watch has noted "growing religious intolerance" and sectarian violence against Coptic Christians in recent years, and a failure by the Egyptian government to effectively investigate properly and prosecute those responsible. Over a hundred Egyptian copts have been killed in sectarian clashes from 2011 to 2017, and many homes and businesses destroyed. In just one province (Minya), 77 cases of sectarian attacks on Copts between 2011 and 2016 have been documented by the Egyptian Initiative for Personal Rights. The abduction and disappearance of Coptic Christian women and girls also remains a serious ongoing problem. Jurisdiction outside Egypt Besides Egypt, the Church of Alexandria has jurisdiction over all of Africa. In addition, the Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church are daughter churches of the Coptic Orthodox Church. Both the Patriarchate of Addis Ababa and all Ethiopia and the Patriarchate of Asmara and all Eritrea acknowledge the supremacy of honor and dignity of the Pope of Alexandria on the basis that both patriarchates were established by the Throne of Alexandria and that they have their roots in the Apostolic Church of Alexandria, and acknowledge that Saint Mark the Apostle is the founder of their churches through the heritage and Apostolic evangelization of the Fathers of Alexandria. Ethiopian Orthodox Tewahedo Church Ethiopia received Christianity next to Jerusalem, through Jesus's own apostle, only a year after Jesus was crucified (Acts 8: 26–39). Christianity became a national religion of Ethiopia, under the dominion of the Church of Alexandria, in the 4th century. The first bishop of Ethiopia, Saint Frumentius, was consecrated as Bishop of Axum by Pope Athanasius of Alexandria in AD 328. From then on, until 1959, the Pope of Alexandria, as Patriarch of All Africa, always named an Egyptian (a Copt) to be the Archbishop of the Ethiopian Church. On 13 July 1948, the Coptic Church of Alexandria and the Ethiopian Orthodox Tewahedo Church reached an agreement concerning the relationship between the two churches. In 1950, the Ethiopian Orthodox Tewahedo Church was granted autocephaly by Pope Joseph II of Alexandria, head of the Coptic Orthodox Church. Five Ethiopian bishops were immediately consecrated by the Pope of Alexandria and Patriarch of All Africa, and were empowered to elect a new Patriarch for their church. This promotion was completed when Joseph II consecrated the first Ethiopian-born Archbishop, Abuna Basilios, as head of the Ethiopian Church on 14 January 1951. In 1959, Pope Cyril VI of Alexandria crowned Abuna Basilios as the first Patriarch of Ethiopia. Patriarch Basilios died in 1971, and was succeeded on the same year by Abuna Theophilos. With the fall of Emperor Haile Selassie I of Ethiopia in 1974, the new Stalinist government arrested Abuna Theophilos and secretly executed him in 1979. The Ethiopian government then ordered the Ethiopian Church to elect Abuna Takla Haymanot as Patriarch of Ethiopia. The Coptic Orthodox Church refused to recognize the election and enthronement of Abuna Takla Haymanot on the grounds that the Synod of the Ethiopian Church had not removed Abuna Theophilos, and that the Ethiopian government had not publicly acknowledged his death, and he was thus still legitimate Patriarch of Ethiopia. Formal relations between the two churches were halted, although they remained in communion with each other. After the death of Abuna Takla Haymanot in 1988, Abune Merkorios who had close ties to the Derg (Communist) government was elected Patriarch of Ethiopia. Following the fall of the Derg regime in 1991, Abune Merkorios abdicated under public and governmental pressure and went to exile in the United States. The newly elected Patriarch, Abune Paulos was officially recognized by the Coptic Orthodox Church in 1992 as the legitimate Patriarch of Ethiopia. Formal relations between the Coptic Church of Alexandria and the Ethiopian Orthodox Tewahedo Church were resumed on 13 July 2007. Abune Paulos died in August 2012. Eritrean Orthodox Tewahedo Church Following the independence of Eritrea from Ethiopia in 1993, the newly independent Eritrean government appealed to Pope Shenouda III of Alexandria for Eritrean Orthodox autocephaly. In 1994, Pope Shenouda ordained Abune Phillipos as first Archbishop of Eritrea. The Eritrean Orthodox Tewahedo Church obtained autocephaly on 7 May 1998, and Abune Phillipos was subsequently consecrated as first Patriarch of Eritrea. The two churches remain in full communion with each other and with the other Oriental Orthodox Churches, although the Coptic Orthodox Church, along with the Ethiopian Orthodox Tewahedo Church does not recognize the deposition of the third Patriarch of Eritrea, Abune Antonios. Around the world The Coptic Orthodox Church has a presence in many countries outside Egypt, including: Africa Asia Australia and Oceania Europe Britain and Ireland France North America United States Canada Mexico South America Official titles of the Patriarch of Alexandria Episcopal titles The leader of the Coptic Orthodox Church is known as Pope of Alexandria and Patriarch of all Africa on the Holy See of St. Mark the Apostle. His full title is Pope, Patriarch and Lord Archbishop of the Great City of Alexandria on the Holy Orthodox and Apostolic Throne of Saint Mark the Evangelist and Holy Apostle that is, in Egypt, Pentapolis, Libya, Nubia, Sudan, Ethiopia, Eritrea and all Africa. The Successor of St. Mark the Evangelist, Holy Apostle and Martyr, on the Holy Apostolic Throne of the Great City of Alexandria. Pope of Alexandria, being the Diocesan Bishop of the Great and Ancient Metropolis of Alexandria, that is in Alexandria and the metropolitan province of Greater Cairo. Elder Metropolitan Archbishop of the Egyptian Province. Primate of Egypt, Pentapolis, Libya, Nubia and Sudan. Father of Fathers. Shepherd of Shepherds. Hierarch of all Hierarchs. Honorary titles The Dean of the Great Catechetical School of Theology of Alexandria. The Ecumenical (Universal) Judge (Arbitrator) of the Holy Apostolic and Catholic (Universal) Church. The 13th among the Holy Apostles. The Pillar and Defender of the Holy, Catholic (Universal), Apostolic Church and of the Orthodox Doctrine. Historical evolution of the ecclesiastical title The title of "pope" has been attributed to the Patriarch of Alexandria since the papacy of Heraclas, the 13th Pope of Alexandria. All the clergy of Alexandria and Lower Egypt honored him with the title papas, which means "father" as the archbishop and metropolitan having authority over all bishops, within the Egyptian province, who are under his jurisdiction. Alexandria, while the ecclesiastical and provincial capital, also had the distinction as being the place where Saint Mark was martyred. The title "Patriarch" originally referred to a clan leader or head of a familial lineage. Ecclesiastically it means a bishop of high rank and was originally used as a title for the bishops of Alexandria, Antioch, Jerusalem, Rome, and Constantinople. For the Coptic Pope, this title was "Pope of Alexandria and all Africa on the Holy Apostolic Throne of Saint Mark the Evangelist," that is "of Egypt". The title of "Patriarch" was first used around the time of the Third Ecumenical Council of Ephesus, convened in AD 431, and ratified at Chalcedon in AD 451. Only the Patriarch of Alexandria has the double title of "Pope" and "Patriarch" among the Eastern Orthodox and Oriental Orthodox ecumenical church heads. Consolidation of Papal control Under the guidance of Pope Shenouda, the church underwent a large transformation that allowed him to hold greater authority than any previous pope. Writing in 2013, the theologian Samuel Tadros stated "Today's Coptic Church as an institution is built solely on his vision". Modern Issues Internal church disputes Pope Shenouda Vs. Father Matta El Meskeen Pope Shenouda III was criticized by the prominent monk Father Matta El Meskeen for the church's strong links with the Egyptian government under the dictator Hosni Mubarak. As the dispute began to grow, Shenouda explicitly denounced Matta's thoughts, labelling some of his writings "heresies". In turn, Matta promoted a radical focus upon personal faith in contrast to institutional religion and ecclesiastical authority. Shenouda, however, was heavily involved in politics and keen to extend the church's influence over the social lives of Copts. Pope Shenouda III, eventually banned Matta's books in Coptic churches- a ban which would be maintained for four-decades. He also restricted Father Matta to the monastery. Despite this Fr. Matta's writings continued to widely influential across the Christian world, most notably among theological giants like the Russian Orthodox Seraphim Rose of Alaska and the Protestant Roger Schultz of Taizé. After Fr Matta's death, Pope Shenouda sought to eliminate the theologian's legacy and break up his following in the Monastery of St. Macarius. The Pope moved some his sympathizes away and brought in monks who were loyal to the papacy. Upon the ascension of Pope Tawadros II, he reversed the decisions of Pope Shenouda. He ended the ban on Fr. Matta's writings and even installed a follower of Matta as the bishop over the monastery. Father Reweis Aziz Khalil child sexual abuse case On 12 July 2020, Sally Zakhari began a series of posts on Facebook and Instagram in which she accused the now defrocked Hegomen Reweis Aziz Khalil of sexual assault when she was between the ages of 11 and 12. Zakhari said that church leaders were aware of several sexual assaults perpetrated by Khalil in his service as a priest across the U.S. for around 22 years, and refused to act on it. The incident sparked other reports of sexual assault and generated debate among church laity, with some in the American Coptic community describing the fallout of the incident as creating a "Coptic #MeToo movement". Administration The Coptic Orthodox Patriarchate of Alexandria is governed by its Holy Synod, which is headed by the Patriarch of Alexandria. Under his authority are the metropolitan archbishops, metropolitan bishops, diocesan bishops, patriarchal exarchs, missionary bishops, auxiliary bishops, suffragan bishops, assistant bishops, chorbishops and the patriarchal vicars for the Church of Alexandria. They are organized as follows: Current Pope is Pope Tawadrous the Second Pope number 118 16 metropolitanates, out of which 12 metropolitanates are in Egypt, one metropolitanate in the Near East, one in Europe, one in the US and one in Africa; served by two metropolitan archbishops and 14 metropolitan bishops; out of the 16 hierarchs, one metropolitan archbishop is in the Near East, one metropolitan archbishop in Egypt, while 11 metropolitan bishops are in Egypt, one metropolitan bishop in Europe, one metropolitan bishop in the US and one metropolitan bishop in Africa. 72 dioceses with 70 diocesan bishops are in Egypt, 15 diocesan bishops are in Europe, 13 diocesan bishops are in North America, two diocesan bishops are in South America, two diocesan bishops are in Sudan, and finally one diocesan bishop and one Abbot of a Monastery are in Australia. one suffragan dioceses, with one suffragan bishop in North America. six auxiliary bishops, with two auxiliary bishops for dioceses in Egypt and four auxiliary bishops in North America. 12 assistant bishops in Egypt for 12 suffragan dioceses within an archdiocese under the Patriarch's jurisdiction; five patriarchal exarchates, with one patriarchal exarch in Africa, one patriarchal exarch in North America and three patriarchal exarchs in Egypt. 13 bishop abbots for 11 patriarchal monasteries in Egypt, one patriarchal monastery in Australia and one patriarchal monastery in Germany two general bishops, patriarchal emissary at large in Egypt and abroad. five general bishops, administrators of patriarchal institutions in Egypt. one hegumen in the capacity of grand economos, patriarchal vicar for Alexandria. one hegumen as administrative patriarchal vicar for Cairo.

natures. Nevertheless, this is the doctrinal perception that makes the apparent difference which separated the Oriental Orthodox from the Eastern Orthodox. The council's findings were rejected by many of the Christians on the fringes of the Byzantine Empire, including Egyptians, Syriacs, Armenians, and others. From that point onward, Alexandria would have two patriarchs: the non-Chalcedonian native Egyptian one, now known as the Coptic Pope of Alexandria and Patriarch of All Africa on the Holy Apostolic See of St. Mark, and the Melkite or Imperial Patriarch, now known as the Greek Orthodox Patriarch of Alexandria. Almost the entire Egyptian population rejected the terms of the Council of Chalcedon and remained faithful to the native Egyptian Church (now known as the Coptic Orthodox Church). Those who supported the Chalcedonian definition remained in communion with the other leading imperial churches of Rome and Constantinople. The non-Chalcedonian party became what is today called the Oriental Orthodox Church. The Coptic Orthodox Church regards itself as having been misunderstood at the Council of Chalcedon. There was an opinion in the Church that viewed that perhaps the Council understood the Church of Alexandria correctly, but wanted to curtail the existing power of the Alexandrine Hierarch, especially after the events that happened several years before at Constantinople from Pope Theophilus of Alexandria towards Patriarch John Chrysostom and the unfortunate turnouts of the Second Council of Ephesus in AD 449, where Eutychus misled Pope Dioscorus and the Council in confessing the Orthodox Faith in writing and then renouncing it after the council, which in turn, had upset Rome, especially that the tome which was sent was not read during the council sessions. To make things even worse, the Tome of Leo of Rome was, according to the Alexandria School of Theology, particularly in regards to the definition of Christology, considered influenced by Nestorian heretical teachings. So, due to the above-mentioned, especially in the consecutive sequences of events, the Hierarchs of Alexandria were considered holding too much of power from one hand, and on the other hand, due to the conflict of the Schools of Theology, there would be an impasse and a scapegoat, i.e. Pope Dioscorus. The Tome of Leo has been widely criticized (surprisingly by Roman Catholic and Eastern Orthodox scholars) in the past 50 years as a much less than perfect orthodox theological doctrine. By anathematizing Pope Leo because of the tone and content of his tome, as per Alexandrine Theology perception, Pope Dioscorus was found guilty of doing so without due process; in other words, the Tome of Leo was not a subject of heresy in the first place, but it was a question of questioning the reasons behind not having it either acknowledged or read at the Second Council of Ephesus in AD 449. Pope Dioscorus of Alexandria was never labeled as heretic by the council's canons. Copts also believe that the Pope of Alexandria was forcibly prevented from attending the third congregation of the council from which he was ousted, apparently the result of a conspiracy tailored by the Roman delegates. Before the current positive era of Eastern and Oriental Orthodox dialogues, Chalcedonians sometimes used to call the non-Chalcedonians "Monophysites", though the Coptic Orthodox Church in reality regards Monophysitism as a heresy. The Chalcedonian doctrine in turn came to be known as "Dyophysite". A term that comes closer to Coptic Orthodoxy is Miaphysite, which refers to a conjoined nature for Christ, both human and divine, united indivisibly in the Incarnate Logos. The Coptic Orthodox Church believes that Christ is perfect in his divinity, and he is perfect in his humanity, but his divinity and his humanity were united in one nature called "the nature of the incarnate word", which was reiterated by Saint Cyril of Alexandria. Copts, thus, believe in two natures "human" and "divine" that are united in one hypostasis "without mingling, without confusion, and without alteration". These two natures "did not separate for a moment or the twinkling of an eye" (Coptic Liturgy of Saint Basil of Caesarea). From Chalcedon to the Arab conquest of Egypt Prior to Chalcedon, the Imperial Church's main division stemmed from Nestorianism, eventually leading the Church of the East to declare its independence in AD 424. After the Council of Chalcedon in AD 451, the Coptic Church and its hierarchy felt suspicious of what they believed were Nestorian elements within the Chalcedonian Church. As a result, the anti-Chalcedon partisan, Timotheos Aelurus, consigned himself to depose the Chalcedonian Pope of Alexandria, Proterius of Alexandria, and to set himself up as the Pope of Alexandria in opposition to the Chalcedonian Church. Copts suffered under the rule of the Byzantine Empire. The Melkite patriarchs, appointed by the emperors as both spiritual leaders and civil governors, massacred those Egyptians they considered heretics. Many were tortured and martyred in attempts to force their acceptance of the Chalcedonian terms, but the Egyptians remained loyal to the Cyrillian Miaphysitism. One of the most renowned Egyptian saints of the period is Saint Samuel the Confessor. Muslim conquest of Egypt The Muslim invasion of Egypt took place in AD 639. Relying on eyewitness testimony, Bishop John of Nikiu in his Chronicle provides a graphic account of the invasion from a Coptic perspective. Although the Chronicle has only been preserved in an Ethiopic (Ge'ez) text, some scholars believe that it was originally written in Coptic. John's account is critical of the invaders who he says "despoiled the Egyptians of their possessions and dealt cruelly with them", and he vividly details the atrocities committed by the Muslims against the native population during the conquest:And when with great toil and exertion they had cast down the walls of the city, they forthwith made themselves masters of it, and put to the sword thousands of its inhabitants and of the soldiers, and they gained an enormous booty, and took the women and children captive and divided them amongst themselves, and they made that city a desolation. Though critical of the Muslim commander (Amr ibn al-As), who, during the campaign, he says "had no mercy on the Egyptians, and did not observe the covenant they had made with him, for he was of a barbaric race", he does note that following the completion of the conquest, Amr "took none of the property of the Churches, and he committed no act of spoilation or plunder, and he preserved them throughout all his days." Despite the political upheaval, the Egyptian population remained mainly Christian. However, gradual conversions to Islam over the centuries had changed Egypt from a Christian to a largely Muslim country by the end of the 12th century. Another scholar writes that a combination of "repression of Coptic revolts", Arab-Muslim immigration, and Coptic conversion to Islam resulted in the demographic decline of the Copts. Egypt's Umayyad rulers taxed Christians at a higher rate than Muslims, driving merchants towards Islam and undermining the economic base of the Coptic Church. Although the Coptic Church did not disappear, the Umayyad tax policies made it difficult for the church to retain the Egyptian elites. Under Islamic rule (640–1800) In 969, Egypt entered the Fatimid dynasty (in Egypt from 969 to 1171), who adopted a largely favorable attitude toward the Christians. The major exception to this was the persecution led by Caliph al-Hakim between 1004 and 1013, which included clothing regulations, prohibition of publicly celebrating Christian festivals, and dismissal of Christian and Jewish functionaries. However, at the end of his reign al-Hakim rescinded these measures, allowing the Coptics to regain privileged positions within the administration. The Coptic patriarchal residence moved from Alexandria to Cairo during the patriarchate of Cyril II (1078–92). This move was at the demand of the grand vizier Badr al-Jamali, who insisted that the pope establish himself in the capital. When Saladin entered Egypt in 1163, this ushered in an government focused on defending Sunni Islam. Christians were again discriminated against, and meant to show modesty in their religious ceremonies and buildings. In 1798, the French invaded Egypt unsuccessfully and the British helped the Turks to regain power over Egypt under the Muhammad Ali dynasty. From the 19th century to the 1952 revolution The position of Copts began to improve early in the 19th century under the stability and tolerance of the Muhammad Ali Dynasty. The Coptic community ceased to be regarded by the state as an administrative unit. In 1855 the jizya tax was abolished by Sa'id Pasha. Shortly thereafter, the Copts started to serve in the Egyptian army. Towards the end of the 19th century, the Coptic Church underwent phases of new development. In 1853, Pope Cyril IV established the first modern Coptic schools, including the first Egyptian school for girls. He also founded a printing press, which was only the second national press in the country. The Pope established very friendly relations with other denominations, to the extent that when the Greek Patriarch in Egypt had to absent himself from the country for a long period of time, he left his Church under the guidance of the Coptic Patriarch. The Theological College of the School of Alexandria was reestablished in 1893. It began its new history with five students, one of whom was later to become its dean. Today it has campuses in Alexandria and Cairo, and in various dioceses throughout Egypt, as well as outside Egypt. It has campuses in New Jersey, Los Angeles, Sydney, Melbourne, and London, where potential clergymen and other qualified men and women study many subjects, including theology, church history, missionary studies, and the Coptic language. Present day In 1959, the Ethiopian Orthodox Tewahedo Church was granted its first own Patriarch by Pope Cyril VI. Furthermore, the Eritrean Orthodox Tewahedo Church similarly became independent of the Ethiopian Orthodox Tewahedo Church in 1994, when four bishops were consecrated by Pope Shenouda III of Alexandria to form the basis of a local Holy Synod of the Eritrean Church. In 1998, the Eritrean Orthodox Tewahedo Church gained its autocephaly from the Coptic Orthodox Church when its first Patriarch was enthroned by Pope Shenouda III. These three churches remain in full communion with each other and with the other Oriental Orthodox churches. The Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church do acknowledge the Honorary Supremacy of the Coptic Orthodox Patriarch of Alexandria, since the Church of Alexandria is technically their Mother Church. Upon their selection, both Patriarchs (Ethiopian & Eritrean) must receive the approval and communion from the Holy Synod of the Apostolic See of Alexandria before their enthronement. Since the 1980s theologians from the Oriental (non-Chalcedonian) Orthodox and Eastern (Chalcedonian) Orthodox churches have been meeting in a bid to resolve theological differences, and have concluded that many of the differences are caused by the two groups using different terminology to describe the same thing. In the summer of 2001, the Coptic Orthodox and Greek Orthodox Patriarchates of Alexandria agreed to mutually recognize baptisms performed in each other's churches, making re-baptisms unnecessary, and to recognize the sacrament of marriage as celebrated by the other. Previously, if a Coptic Orthodox and Greek Orthodox wanted to get married, the marriage had to be performed twice, once in each church, for it to be recognized by both. Now it can be done in only one church and be recognized by both. In Tahrir Square, Cairo, on Wednesday 2 February 2011, Coptic Christians joined hands to provide a protective cordon around their Muslim neighbors during salat (prayers) in the midst of the 2011 Egyptian Revolution. On 17 March 2012, the Coptic Orthodox Pope, Pope Shenouda III died, leaving many Copts mourning and worrying as tensions rose with Muslims. Pope Shenouda III constantly met with Muslim leaders in order to create peace. Many were worried about Muslims controlling Egypt as the Muslim Brotherhood won 70% of the parliamentary elections. On 4 November 2012, Bishop Tawadros was chosen as the 118th Pope. In a ritual filled with prayer, chants and incense at Abbasiya cathedral in Cairo, the 60-year-old bishop's name was picked by a blindfolded child from a glass bowl in which the names of two other candidates had also been placed. The enthronement was scheduled on 18 November 2012. Fasting, liturgy and canonical hours According to Christian tradition and Canon Law, the Coptic Orthodox Church only ordains men to the priesthood and episcopate, and if they wish to be married, they must be married before they are ordained. In this respect, they follow the same practices as all other Oriental Orthodox Churches, as well as all of the Eastern Orthodox Church. Traditionally, the Coptic language was used in church services, and the scriptures were written in the Coptic alphabet. However, due to the Arabisation of Egypt, service in churches started to witness increased use of Arabic, while preaching is done entirely in Arabic. Local vernacular languages are used, in conjunction with Arabic and/or Coptic, during services outside Egypt. The liturgical calendar of the Coptic Orthodox Church is the Coptic calendar (also called the Alexandrian Calendar). This calendar is based on the Egyptian calendar of Ancient Egypt. Coptic Orthodox Christians celebrate Christmas on 29 Koiak, which corresponds to 7 January in the Gregorian Calendar and 25 December in the Julian Calendar. Coptic Christmas was adopted as an official national holiday in Egypt in 2002. Communicants of the Coptic Orthodox Church use a breviary known as the Agpeya to pray the canonical hours at seven fixed prayer times while facing in the eastward direction, in anticipation of the Second Coming of Jesus; this Christian practice has its roots in Psalm 119:164, in which the prophet David prays to God seven times a day. Church bells enjoin Christians to pray at these hours. Before praying, they wash their hands and face in order to be clean before and present their best to God; shoes are removed in order to acknowledge that one is offering prayer before a holy God. During each of the seven fixed prayer times, Coptic Orthodox Christians pray "prostrating three times in the name of the Trinity; at the end of each Psalm … while saying the 'Alleluia';" and forty-one times for each of the Kyrie eleisons present in a canonical hour. In the Coptic Orthodox Church, it is customary for women to wear a Christian headcovering when praying. All churches of the Coptic Orthodox Church are designed to face the eastward direction of prayer and efforts are made to remodel churches obtained from other Christian denominations that are not built in this fashion. With respect to Eucharistic discipline, Coptic Orthodox Christians fast from midnight onwards before receiving the sacrament of Holy Communion. They fast every Wednesday and Friday of the year (Wednesdays in remembrance of the betrayal of Christ, and on Fridays, in remembrance of His crucifixion and death). In total, the number of fast days in a year for Coptic Orthodox Christians numbers around 240, with the fasts for Advent and Lent being forty-three days and fifty-five days, respectively. In August, before the celebration of the Dormition of the Mother of God, Coptic Christians fast fifteen days; fasting is also done before the feast of Feast of Saints Peter and Paul, starting from the day of Pentecost. Demographics Available Egyptian census figures and other third party survey reports have not reported more than 4 million Coptic Orthodox Christians in Egypt. However media and other agencies, sometimes taking into account the claims of the Church itself, generally approximate the Coptic Orthodox population at 10% of the Egyptian population or 10 million people. The majority of them live in Egypt under the jurisdiction of the Coptic Orthodox Church. Since 2006, Egyptian censuses have not reported on religion and church leaders have alleged that Christians were under-counted in government surveys. In 2017, a government owned newspaper Al Ahram estimated the percentage of Copts at 10 to 15% and the membership claimed by the Coptic Orthodox Church is in the range of 20 to 25 million. There are also significant numbers in the diaspora outside Africa in countries such as the United States, Canada, Australia, France, and Germany. The exact number of Egyptian born Coptic Orthodox Christians in the diaspora is hard to determine and is roughly estimated to be close to 1 million. There are between 150,000 and 200,000 adherents in Sudan. Persecution While Copts have cited instances of persecution throughout their history, Human Rights Watch has noted "growing religious intolerance" and sectarian violence against Coptic Christians in recent years, and a failure by the Egyptian government to effectively investigate properly and prosecute those responsible. Over a hundred Egyptian copts have been killed in sectarian clashes from 2011 to 2017, and many homes and businesses destroyed. In just one province (Minya), 77 cases of sectarian attacks on Copts between 2011 and 2016 have been documented by the Egyptian Initiative for Personal Rights. The abduction and disappearance of Coptic Christian women and girls also remains a serious ongoing problem. Jurisdiction outside Egypt Besides Egypt, the Church of Alexandria has jurisdiction over all of Africa. In addition, the Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church are daughter churches of the Coptic Orthodox Church. Both the Patriarchate of Addis Ababa and all Ethiopia and the Patriarchate of Asmara and all Eritrea acknowledge the supremacy of honor and dignity of the Pope of Alexandria on the basis that both patriarchates were established by the Throne of Alexandria and that they have their roots in the Apostolic Church of Alexandria, and acknowledge that Saint Mark the Apostle is the founder of their churches through the heritage and Apostolic evangelization of the Fathers of Alexandria. Ethiopian Orthodox Tewahedo Church Ethiopia received Christianity next to Jerusalem, through Jesus's own apostle, only a year after Jesus was crucified (Acts 8: 26–39). Christianity became a national religion of Ethiopia, under the dominion of the Church of Alexandria, in the 4th century. The first bishop of Ethiopia, Saint Frumentius, was consecrated as Bishop of Axum by Pope Athanasius of Alexandria in AD 328. From then on, until 1959, the Pope of Alexandria, as Patriarch of All Africa, always named an Egyptian (a Copt) to be the Archbishop of the Ethiopian Church. On 13 July 1948, the Coptic Church of Alexandria and the Ethiopian Orthodox Tewahedo Church reached an agreement concerning the relationship between the two churches. In 1950, the Ethiopian Orthodox Tewahedo Church was granted autocephaly by Pope Joseph II of Alexandria, head of the Coptic Orthodox Church. Five Ethiopian bishops were immediately consecrated by the Pope of Alexandria and Patriarch of All Africa, and were empowered to elect a new Patriarch for their church. This promotion was completed when Joseph II consecrated the first Ethiopian-born Archbishop, Abuna Basilios, as head of the Ethiopian Church on 14 January 1951. In 1959, Pope Cyril VI of Alexandria crowned Abuna Basilios as the first Patriarch of Ethiopia. Patriarch Basilios died in 1971, and was succeeded on the same year by Abuna Theophilos. With the fall of Emperor Haile Selassie I of Ethiopia in 1974, the new Stalinist government arrested Abuna Theophilos and secretly executed him in 1979. The Ethiopian government then ordered the Ethiopian Church to elect Abuna Takla Haymanot as Patriarch of Ethiopia. The Coptic Orthodox Church refused to recognize the election and enthronement of Abuna Takla Haymanot on the grounds that the Synod of the Ethiopian Church had not removed Abuna Theophilos, and that the Ethiopian government had not publicly acknowledged his death, and he was thus still legitimate Patriarch of Ethiopia. Formal relations between the two churches were halted, although they remained in communion with each other. After the death of Abuna Takla Haymanot in 1988, Abune Merkorios who had close ties to the Derg (Communist) government was elected Patriarch of Ethiopia. Following the fall of the Derg regime in 1991, Abune Merkorios abdicated under public and governmental pressure and went to exile in the United States. The newly elected Patriarch, Abune Paulos was officially recognized by the Coptic Orthodox Church in 1992 as the legitimate Patriarch of Ethiopia. Formal relations between the Coptic Church of Alexandria and the Ethiopian Orthodox Tewahedo Church were resumed on 13 July 2007. Abune Paulos died in August 2012. Eritrean Orthodox Tewahedo Church Following the
with Jesus. TFI describes its "Loving Jesus" teaching as a radical form of bridal theology. They believe the church of followers is Christ's bride, called to love and serve him with wifely fervor; however, this bridal theology is taken further, encouraging members to imagine Jesus is joining them during sexual intercourse and masturbation. Male members are cautioned to visualize themselves as women, in order to avoid a homosexual relationship with Jesus. Many TFI publications, and spirit messages claimed to be from Jesus himself, elaborate this intimate, sexual relation they believe Jesus desires and needs. TFI imagines itself as his special "bride" in graphic poetry, guided visualizations, artwork, and songs. Some TFI literature is not brought into conservative countries for fear it may be classified at customs as pornography. The literature outlining this view of Jesus and his desire for a sexual relationship with believers was edited for younger teens, then further edited for children. Controversy Second-generation adults (known as "SGAs") are adults born or reared in TFI. Anti-TFI sentiment has been publicly expressed by some who have left the group; examples include sisters Celeste Jones, Kristina Jones, and Juliana Buhring, who wrote a book on their lives in TFI. TFI members are expected to respect legal and civil authorities where they live. Members have typically cooperated with appointed authorities, even during the police and social-service raids of their communities in the early 1990s. Criticism The Family has been criticized by the press and the anti-cult movement. Ex-members have accused the Family's leadership of following "a policy of lying to outsiders," being "steeped in a history of sexual deviance" and even meddling "in Third World politics". The Family replies that it is a victim of "persecution." In 1971, an organization called FREECOG was founded by concerned parents and others, including deprogrammer Ted Patrick to "free" members of the COG from their involvement in the group. Academics categorize TFI as a "new religious movement" and a cult. At least one individual growing up in the family (Verity Carter) during the Children of God era described being sexually abused "from the age of four by members of the... cult, including her own father". She blames the philosophy of David Berg, who told members that "God was love and love was sex", so that sex should not be limited by age or relationship. Carter also complains of being "repeatedly beaten and whipped for the smallest of transgressions", being denied "music or television or culture," or other "contact with the outside world," so that she had "no idea how the world worked" other than how to manipulate the "systemites" (outsiders), like social workers. Author Don Lattin interviewed numerous members of the Family for his book Jesus Freaks. In a review of his book, Paul Burgarino describes Berg as "drawing from the remnants of hippie life—people with nothing to lose, nowhere to go, and no Christian background" to alert them to deviations in Berg's preaching. One ex-Children of God member, Jerry Golland, describes himself at the time of joining the group as penniless and so depressed that the Children of God scraped him "off the street". Members would "learn to spot, you know... a vulnerable person. We called them sheep", Golland told the Canadian Broadcasting Corporation. Pressure to raise money could also be intense. Ex-member Golland says that members who were good at raising money and distributing the pamphlets were called "Shiners". Those with poor sales were called "Shamers". "If you missed your quota you could not come home for dinner", he said. Notable members (past and present) Joined in adulthood Jeremy Spencer, blues slide guitarist and a founding member of Fleetwood Mac, which he left in 1971 when he joined TFI.

men. Spirit Helpers "Spirit Helpers" include angels, other religious and mythical figures, and departed humans, including celebrities; for example the goddess Aphrodite, the Snowman, Merlin, the Sphinx, Elvis, Marilyn Monroe, Audrey Hepburn, Richard Nixon, and Winston Churchill. The Keys of the Kingdom TFI believes that the Biblical passage "I will give you the keys of the kingdom of heaven, and whatsoever you bind on earth will be bound in heaven, and whatsoever you loose on earth will be loosed in heaven", () refers to an increasing amount of spiritual authority that was given to Peter and the early disciples. According to TFI beliefs, this passage refers to keys that were hidden and unused in the centuries that followed, but were again revealed through Karen Zerby as more power to pray and obtain miracles. TFI members call on the various Keys of the Kingdom for extra effect during prayer. The Keys, like most TFI beliefs, were published in magazines that looked like comic-books in order to make them teachable to children. These beliefs are still generally held and practiced, even after the "reboot" documents of 2010.

One ex-Children of God member, Jerry Golland, describes himself at the time of joining the group as penniless and so depressed that the Children of God scraped him "off the street". Members would "learn to spot, you know... a vulnerable person. We called them sheep", Golland told the Canadian Broadcasting Corporation. Pressure to raise money could also be intense. Ex-member Golland says that members who were good at raising money and distributing the pamphlets were called "Shiners". Those with poor sales were called "Shamers". "If you missed your quota you could not come home for dinner", he said.

Berlin. Background Hammurabi Hammurabi (or Hammurapi), the sixth king of the Amorite First Dynasty of Babylon, ruled from 1792 to 1750 BC (middle chronology). He secured Babylonian dominance over the Mesopotamian plain through military prowess, diplomacy, and treachery. When Hammurabi inherited his father Sin-Muballit's throne, Babylon held little local sway; the local hegemon was Rim-Sin of Larsa. Hammurabi waited until Rim-Sin grew old, then conquered his territory in one swift campaign, leaving his organisation intact. Later, Hammurabi betrayed allies in Eshnunna, Elam, and Mari to gain their territories. Hammurabi had an aggressive foreign policy, but his letters suggest he was concerned with the welfare of his many subjects and was interested in law and justice. He commissioned extensive construction works, and in his letters, he frequently presents himself as his people's shepherd. Justice is also a theme of the prologue to the Code, and "the word translated 'justice' []... is one whose root runs through both prologue and epilogue". Earlier law collections Although Hammurabi's Code was the first Mesopotamian law collection discovered, it was not the first written; several earlier collections survive. These collections were written in Sumerian and Akkadian. They also purport to have been written by rulers. There were almost certainly more such collections, as statements of other rulers suggest the custom was widespread. The similarities between these law collections make it tempting to assume a consistent underlying legal system. As with the Code of Hammurabi, however, it is difficult to interpret the purpose and underlying legal systems of these earlier collections, prompting numerous scholars to question whether this should be attempted. Extant collections include: The Code of Ur-Nammu of Ur. The Code of Lipit-Ishtar of Isin. The Laws of Eshnunna (written by Bilalama or by Dadusha). Another collection, which Martha Roth calls the "Laws of X", but which may simply be the end of the Code of Ur-Nammu. There are additionally thousands of documents from the practice of law, from before and during the Old Babylonian period. These documents include contracts, judicial rulings, letters on legal cases, and reform documents such as that of Urukagina, king of Lagash in the mid-3rd millennium BC, whose reforms combatted corruption. Mesopotamia has the most comprehensive surviving legal corpus from before the Digest of Justinian, even compared to those from ancient Greece and Rome. Copies Louvre stele The first copy of the text found, and still the most complete, is on a stele. The stele is now displayed on the ground floor of the Louvre, in Room 227 of the Richelieu wing. Scholars are divided as to the material of the stele. Some, including the Louvre and Martha Roth, have stated that it is basalt. However, others, including Marc Van De Mieroop and Father Jean-Vincent Scheil—the French Dominican and Assyriologist who wrote the Code's —have stated that it is diorite. At the top is an image of Hammurabi with Shamash, the Babylonian sun god and god of justice. Below the image are about 4,130 lines of cuneiform text: One fifth contain a prologue and epilogue, while the remaining four fifths contain what are generally called the laws. Near the bottom, seven columns of the laws, each with more than eighty lines, were polished and erased in antiquity. The stele was found in three large fragments and reconstructed. It is high, with a circumference is at the summit and at the base. Hammurabi's image is high and wide. The Louvre stele was found at the site of the ancient Elamite city of Susa. Susa is in modern-day Khuzestan Province, Iran (Persia at the time of excavation). The stele was excavated by the French Archaeological Mission under the direction of Jacques de Morgan. Father Jean-Vincent Scheil published the initial report in the fourth volume of the Reports of the Delegation to Persia (). According to Scheil, the stele's fragments were found on the tell of the Susa acropolis (), between December 1901 and January 1902. The few, large fragments made assembly easy. Scheil hypothesised that the stele had been taken to Susa by the Elamite king Shutruk-Nakhunte and that he had commissioned the erasure of several columns of laws to write his legend there. Roth suggests the stele was taken as plunder from Sippar, where Hammurabi lived towards the end of his reign. Other copies Fragments of a second and possibly third stele recording the Code were found along with the Louvre stele at Susa. Over fifty manuscripts containing the laws are known. They were found not only in Susa but also in Babylon, Nineveh, Assur, Borsippa, Nippur, Sippar, Ur, Larsa, and more. Copies were created during Hammurabi's reign, and also after it, since the text became a part of the scribal curriculum. Copies have been found dating from one thousand years after the stele's creation, and a catalogue from the library of Neo-Assyrian king Ashurbanipal (685–631 BC) lists a copy of the "judgments of Hammurabi". The additional copies fill in most of the stele's original text, including much of the erased section. Early scholarship The of the Code was published by Father Jean-Vincent Scheil in 1902, in the fourth volume of the Reports of the Delegation to Persia (). After a brief introduction with details of the excavation, Scheil gave a transliteration and a free translation into French, as well as a selection of images. Editions in other languages soon followed: in German by Hugo Winckler in 1902, in English by C. H. W. Johns in 1903, and in Italian by Pietro Bonfante, also in 1903. The Code was thought to be the earliest Mesopotamian law collection when it was discovered in 1902—for example, C. H. W. Johns' 1903 book was titled The Oldest Code of Laws in the World. The English writer H. G. Wells included Hammurabi in the first volume of The Outline of History, and to Wells too the Code was "the earliest known code of law". However, three earlier collections were discovered afterwards: the Code of Lipit-Ishtar in 1947, the Laws of Eshnunna in 1948, and the Code of Ur-Nammu in 1952. Early commentators dated Hammurabi and the stele to the 23rd century BC. However, this is an earlier estimate than even the "ultra-long chronology" would support. The Code was compiled near the end of Hammurabi's reign. This was deduced partly from the list of his achievements in the prologue. Scheil enthused about the stele's importance and perceived fairness, calling it "a moral and political masterpiece". C. H. W. Johns called it "one of the most important monuments in the history of the human race". He remarked that "there are many humanitarian clauses and much protection is given the weak and the helpless", and even lauded a "wonderful modernity of spirit". John Dyneley Prince called the Code's discovery "the most important event which has taken place in the development of Assyriological science since the days of Rawlinson and Layard". Charles Francis Horne commended the "wise law-giver" and his "celebrated code". James Henry Breasted noted the Code's "justice to the widow, the orphan, and the poor", but remarked that it "also allows many of the old and naïve ideas of justice to stand". Commentators praised the advanced society they believed the Code evinced. Several singled out perceived secularism: Owen Jenkins, for example, but even Charles Souvay for the Catholic Encyclopedia, who opined that unlike the Mosaic Law the Code was "founded upon the dictates of reason". The question of the Code's influence on the Mosaic Law received much early attention. Scholars also identified Hammurabi with the Biblical figure Amraphel, but this proposal has since been abandoned. "Frame" Relief The relief appears to show Hammurabi standing before a seated Shamash. Shamash wears the horned crown of divinity and has a solar attribute, flames, spouting from his shoulders. Contrastingly, Scheil, in his , identified the seated figure as Hammurabi and the standing figure as Shamash. Scheil also held that the scene showed Shamash dictating to Hammurabi while Hammurabi held a scribe's stylus, gazing attentively at the god. Martha Roth lists other interpretations: "that the king is offering the laws to the god; that the king is accepting or offering the emblems of sovereignty of the rod and ring; or—most probably—that these emblems are the measuring tools of the rod-measure and rope-measure used in temple-building". Hammurabi may even be imitating Shamash. It is certain, though, that the draughtsman showed Hammurabi's close links to the divine realm, using composition and iconography. Prologue The prologue and epilogue together occupy one-fifth of the text. Out of around 4,130 lines, the prologue occupies 300 lines and the epilogue occupies 500. They are in ring composition around the laws, though there is no visual break distinguishing them from the laws. Both are written in poetic style, and, as William W. Davies wrote, "contain much... which sounds very like braggadocio". The 300-line prologue begins with an etiology of Hammurabi's royal authority (1–49). Anum, the Babylonian sky god and king of the gods, granted rulership over humanity to Marduk. Marduk chose the centre of his earthly power to be Babylon, which in the real world worshipped him as its tutelary god. Marduk established the office of kingship within Babylon. Finally, Anum, along with the Babylonian wind god Enlil, chose Hammurabi to be Babylon's king. Hammurabi was to rule "to prevent the strong from oppressing the weak" (37–39: ). He was to rise like Shamash over the Mesopotamians (the , literally the "black-headed people") and illuminate the land (40–44). Hammurabi then lists his achievements and virtues (50–291). These are expressed in noun form, in the Akkadian first person singular nominal sentence construction "[noun]... " ("I am [noun]"). The first nominal sentence (50–53) is short: "I am Hammurabi, the shepherd, selected by the god Enlil" (). Then Hammurabi continues for over 200 lines in a single nominal sentence with the delayed to the very end (291). Hammurabi repeatedly calls himself , "pious" (lines 61, 149, 241, and 272). The metaphor of Hammurabi as his people's shepherd also recurs. It was a common metaphor for ancient Near Eastern kings, but is perhaps justified by Hammurabi's interest in his subjects' affairs. His affinities with many different gods are stressed throughout. He is portrayed as dutiful in restoring and maintaining temples and peerless on the battlefield. The list of his accomplishments has helped establish that the text was written late in Hammurabi's reign. After the list, Hammurabi explains that he fulfilled Marduk's request to establish "truth and justice" () for the people (292–302), although the prologue never directly references the laws. The prologue ends "at that time:" (303: ) and the laws begin. Epilogue Unlike the prologue, the 500-line epilogue is explicitly related to the laws. The epilogue begins (3144'–3151'): "these are the just decisions which Hammurabi... has established" (). He exalts his laws and his magnanimity (3152'–3239'). He then expresses a hope that "any wronged man who has a lawsuit" () may have the laws of the stele read aloud to him and know his rights (3240'–3256'). This would bring Hammurabi praise (3257'–3275') and divine favour (3276'–3295'). Hammurabi wishes for good fortune for any ruler who heeds his pronouncements and respects his stele (3296'–3359'). However, he invokes the wrath of the gods on any man who disobeys or erases his pronouncements (3360'–3641', the end of the text). The epilogue contains much legal imagery, and the phrase "to prevent the strong from oppressing the weak" (3202'–3203': ) is reused from the prologue. However, the king's main concern appears to be ensuring that his achievements are not forgotten and his name not sullied. The list of curses heaped upon any future defacer is 281 lines long and extremely forceful. Some of the curses are very vivid: "may the god Sin... decree for him a life that is no better than death" (3486'–3508': ); "may he [the future defacer] conclude every day, month, and year of his reign with groaning and mourning" (3497'–3501': ); may he experience "the spilling of his life force like water" (3435'–3436': ). Hammurabi implores a variety of gods individually to turn their particular attributes against the defacer. For example: "may the [storm] god Adad... deprive him of the benefits of rain from heaven and flood from the springs" (3509'–3515': ); "may the god [of wisdom] Ea... deprive him of all understanding and wisdom, and may he lead him into confusion" (3440'–3451': ). Gods and goddesses are invoked in this order: Anum (3387'–3394') Enlil (3395'–3422') Ninlil (3423'–3439') Ea (3440'–3458') Shamash (3459'–3485') Sin (3486'–3508') Adad (3509'–3525') Zababa (3526'–3536') Ishtar (3537'–3573') Nergal (3574'–3589') Nintu (3590'–3599') Ninkarrak (3600'–3619') All the gods (3620'–3635') Enlil, a second time (3636'–3641') Laws The Code of Hammurabi is the longest and best-organised legal text from the ancient Near East, as well as the best-preserved. The classification below (columns 1–3) is Driver & Miles', with several amendments, and Roth's translation is used. Laws represented by letters are those reconstructed primarily from documents other than the Louvre stele. Theories of purpose The purpose and legal authority of the Code have been disputed since the mid-20th century. Theories fall into three main categories: that it is legislation, whether a code of law or a body of statutes; that it is a sort of law report, containing records of past cases and judgments; and that it is an abstract work of jurisprudence. The jurisprudence theory has gained much support within Assyriology. Legislation The term "code" presupposes that the document was intended to be enforced as legislation. It was used by Scheil in his , and widely adopted afterwards. C. H. W. Johns, one of the most prolific early commentators on the document, proclaimed that "the Code well deserves its name". Recent Assyriologists have used the term without comment, as well as scholars outside Assyriology. However, only if the text was intended as enforced legislation can it truly be called a code of law and its provisions laws. The document, on first inspection, resembles a highly organised code similar to
the Code does bear striking similarities to other works of Mesopotamian scholarship. Key points of similarity are the list format and the order of the items, which Ann Guinan describes as a complex "serial logic". Marc Van De Mieroop explains that, in common with other works of Mesopotamian scholarship such as omen lists, king lists, and god lists, the entries of the Code of Hammurabi are arranged according to two principles. These are "opposition"—whereby a variable in one entry is altered to make another entry—and "pointillism"—whereby new conditions are added to an entry, or paradigmatic series pursued, to generate a sequence. Van De Mieroop provides the following examples: Laws 215 and 218 illustrate the principle of opposition: one variable of the first law, the outcome of the operations, is altered to create the second. Here, following the principle of pointillism, circumstances are added to the first entry to create more entries. Pointillism also lets list entries be generated by following paradigmatic series common to multiple branches of scholarship. It can thus explain the implausible entries. For example, in the case of the goat used for threshing (law 270), the previous laws concern other animals that were used for threshing. The established series of domesticated beasts dictated that a goat come next. Wolfram von Soden, who decades earlier called this way of thinking ("list science"), often denigrated it. However, more recent writers, such as Marc Van De Mieroop, Jean Bottéro, and Ann Guinan, have either avoided value judgments or expressed admiration. Lists were central to Mesopotamian science and logic, and their distinctive structural principles let entries be generated infinitely. Linking the Code to the scribal tradition within which "list science" emerged also explains why trainee scribes copied and studied it for over a millennium. The Code appears in a late Babylonian (7th–6th century BC) list of literary and scholarly texts. No other law collection became so entrenched in the curriculum. Rather than a code of laws, then, it may be a scholarly treatise. Much has been written on what the Code suggests about Old Babylonian society and its legal system. For example, whether it demonstrates that there were no professional advocates, or that there were professional judges. Scholars who approach the Code as a self-contained document renounce such claims. Underlying principles One principle widely accepted to underlie the Code is , or "eye for an eye". Laws 196 and 200 respectively prescribe an eye for an eye and a tooth for a tooth when one man destroys another's. Punishments determined by could be transferred to the sons of the wrongdoer. For example, law 229 states that the death of a homeowner in a house collapse necessitates the death of the house's builder. The following law 230 states that if the homeowner's son died, the builder's son must die also. Persons were not equal before the law; not just age and profession but also class and gender dictated the punishment or remedy they received. Three main kinds of person, , , and (male)/ (female), are mentioned throughout the Code. A / was a male/female slave. As for and , though contentious, it seems likely that the difference was one of social class, with meaning something like "gentleman" and something like "commoner". The penalties were not necessarily stricter for a than an : a 's life may have been cheaper, but so were some of his fines. There was also inequality within these classes: laws 200 and 202, for example, show that one could be of higher rank than another. Martha Roth has shown that ideas of shame and honour motivated certain laws. Most readers will also be struck by the violence of many of the punishments. This prompted Driver and Miles to remark that "the Babylonians believed in corporal punishments... and did not highly value human life". The above principles are distant in spirit from modern systems of common and civil law, but some may be more familiar. One such principle is the presumption of innocence; the first two laws of the stele prescribe punishments, determined by , for unsubstantiated accusations. Written evidence was valued highly, especially in matters of contract. One crime was given only one punishment. The laws also recognized the importance of the intentions of a defendant. Lastly, the Code's establishment on public stelae was supposedly intended to increase access to justice. Whether or not this was true, suggesting that a wronged man have the stele read aloud to him (lines 3240'–3254') is a concrete measure in this direction, given the inaccessibility of scribal education in the Old Babylonian period. One last question is what source the Code claims for its legitimacy. The prologue asserts that Hammurabi was chosen by the gods. Raymond Westbrook observed that in ancient Near Eastern law, "the king was the primary source of legislation". However, they could delegate their god-given legal authority to judges. However, as Owen B. Jenkins observed, the prescriptions themselves bear "an astonishing absence... of all theological or even ceremonial law". Language The laws are written in the Old Babylonian dialect of Akkadian. Their style is regular and repetitive, and today they are a standard set text for introductory Akkadian classes. However, as A. Leo Oppenheim summarises, the cuneiform signs themselves are "vertically arranged... within boxes placed in bands side by side from right to left", an arrangement already antiquated by Hammurabi's time. Since Akkadian learners today tend to begin by studying later phases of cuneiform, where the signs have been rotated ninety degrees, they have to turn their head on one side to read the Louvre stele. The laws are expressed in casuistic format: they are conditional sentences with the case detailed in the protasis ("if" clause) and the remedy given in the apodosis ("then" clause). The protasis begins , "if", except when it adds to circumstances already specified in a previous law (e.g. laws 36, 38, and 40). The preterite is used for simple past verbs in the protasis, or possibly for a simple conditional. The perfect often appears at the end of the protasis after one or more preterites to convey sequence of action, or possibly a hypothetical conditional. The durative, sometimes called the "present" in Assyriology, may express intention in the laws. For ease of English reading, some translations give preterite and perfect verbs in the protasis a present sense. In the apodosis, the verbs are in the durative, though the sense varies between permissive—"it is permitted that x happen"—and instructive—"x must/will happen". In both protasis and apodosis, sequence of action is conveyed by suffixing verbs with , "and". can also have the sense "but". The Code is relatively well-understood, but some items of its vocabulary are controversial. As mentioned, the terms and have proved difficult to translate. They probably denote respectively a male member of a higher and lower social class. Wolfram von Soden, in his Akkadisches Handwörterbuch, proposed that was derived from , "to bow down/supplicate". As a word for a man of low social standing, it has endured, possibly from a Sumerian root, into Arabic (), Italian (), Spanish (), and French (). However, some earlier translators, also seeking to explain the 's special treatment, translated it as "leper" and even "noble". Some translators have supplied stilted readings for , such as "seignior", "elite man", and "member of the aristocracy"; others have left it untranslated. Certain legal terms have also proved difficult to translate. For example, and can denote the law in general as well as individual laws, verdicts, divine pronouncements and other phenomena. can likewise denote the law in general as well as a kind of royal decree. Relation to other law collections Other Mesopotamian The Code of Hammurabi bears strong similarities to earlier Mesopotamian law collections. Many purport to have been written by rulers, and this tradition was probably widespread. Earlier law collections express their god-given legitimacy similarly. Like the Code of Hammurabi, they feature prologues and epilogues: the Code of Ur-Nammu has a prologue, the Code of Lipit-Ishtar a prologue and an epilogue, and the Laws of Eshnunna an epilogue. Also, like the Code of Hammurabi, they uphold the "one crime, one punishment" principle. The cases covered and language used are, overall, strikingly similar. Scribes were still copying e.g. the Code of Ur-Nammu when Hammurabi produced his own Code. This suggests that earlier collections may have not only resembled the Code but influenced it. Raymond Westbrook maintained that there was a fairly consistent tradition of "ancient Near Eastern law" which included the Code of Hammurabi, and that this was largely customary law. Nonetheless, there are differences: for example, Stephen Bertman has suggested that where earlier collections are concerned with compensating victims, the Code is concerned with physically punishing offenders. Additionally, the above conclusions of similarity and influence apply only to the law collections themselves. The actual legal practices from the context of each code are mysterious. The Code of Hammurabi also bears strong similarities to later Mesopotamian law collections: to the casuistic Middle Assyrian Laws and to the Neo-Babylonian Laws, whose format is largely relative ("a man who..."). It is easier to posit direct influence for these later collections, given the Code's survival through the scribal curriculum. Lastly, although influence is more difficult to trace, there is evidence that the Hittite laws may have been part of the same tradition of legal writing outside Mesopotamia proper. Mosaic, Graeco-Roman, and modern The relationship of the Code of Hammurabi to the Mosaic Law, specifically the Covenant Code of Exodus 20:22–23:19, has been a subject of discussion since its discovery. Friedrich Delitzsch argued the case for strong influence in a 1902 lecture, in one episode of the "" ("Babel and Bible", or "Panbabylonism") debate on the influence of ancient Mesopotamian cultures on ancient Israel. However, he was met with strong resistance. There was cultural contact between Mesopotamia and the Levant, and Middle Bronze Age tablets of casuistic cuneiform law have been found at Hazor. There are also similarities between the Code of Hamurabi and the Covenant Code: in the casuistic format, in principles such as ("eye for an eye"), and in the content of the provisions. Some similarities are striking, such as in the provisions concerning a man-goring ox (Code of Hammurabi laws 250–252, Exodus 21:28–32). Certain writers have posited direct influence: David P. Wright, for example, asserts that the Covenant Code is "directly, primarily, and throughout dependent upon the Laws of Hammurabi", "a creative rewriting of Mesopotamian sources... to be viewed as an academic abstraction rather than a digest of laws". Others posit indirect influence, such as via Aramaic or Phoenician intermediaries. The consensus, however, is that the similarities are a result of inheriting common traditions. In 1916, George A. Barton cited "a similarity of antecedents and of general intellectual outlook". More recently, David Winton Thomas has stated: "There is no ground for assuming any direct borrowing by the Hebrew from the Babylonian. Even where the two sets of laws differ little in the letter, they differ much in the spirit". The influence of the Code of Hammurabi on later law collections is difficult to establish. Marc Van De Mieroop suggests that it may have influenced the Greek Gortyn Code and the Roman Twelve Tables. However, even Van De Mieroop acknowledges that most Roman law is not similar to the Code, or likely to have been influenced by it. Knowing the Code's influence on modern law requires knowing its influence on Mosaic and Graeco-Roman law. Since this is contentious, commentators have restricted themselves to observing similarities and differences between the Code and, e.g., United States law and medieval law. Some have remarked that the punishments found in the Code are no more severe, and, in some cases, less so. Law 238 stipulates that a sea captain, ship-manager, or ship charterer that saved a ship from total loss was only required to pay one-half the value of the ship to the ship-owner. In the Digesta seu Pandectae (533), the second volume of the codification of laws ordered by Justinian I (527–565) of the Eastern Roman Empire, a legal opinion written by the Roman jurist Paulus at the beginning of the Crisis of the Third Century in 235 AD was included about the Lex Rhodia ("Rhodian law") that articulates the general average principle of marine insurance established on the island of Rhodes in approximately 1000 to 800 BC as a member of the Doric Hexapolis, plausibly by the Phoenicians during the proposed Dorian invasion and emergence of the purported Sea Peoples during the Greek Dark Ages (c. 1100 – c. 750) that led to the proliferation of the Doric Greek dialect. The law of general average constitutes the fundamental principle that underlies all insurance. Reception outside Assyriology The Code is often referred to in legal scholarship, where its provisions are assumed to be laws, and the document is assumed to be a true code of laws. This is also true outside academia. Some writers incorrectly state that the Code of Hammurabi is the oldest code of laws. All stress its importance and positive attributes: the Louvre, for example, calls it "the emblem of the Mesopotamian civilization". Iraq's Hammurabi Human Rights Organization was named after the Code. Hammurabi leads Babylon in five of the six Civilization video games, and in Civilization VI his leader ability is "Ninu Ilu Sirum". This is an early reading of the Code's incipit, ("when the august god Anu[m]..."). The soundtrack to the South Korean television series Ms. Hammurabi, which is about a judge, features the track "Code of Hammurabi". The thrash metal band Testament's 2020 album Titans of Creation also features a track called "Code of Hammurabi". There is a relief portrait of Hammurabi over the doors to the House Chamber of the U.S. Capitol, along with portraits of 22 others "noted for their work in establishing the principles that underlie American law". There are replicas of the Louvre stele in institutions around the world, including: the Headquarters of the United Nations in New York City, the Peace Palace in The Hague (seat of the International Court of Justice), the National Museum of Iran in Tehran, the Pergamon Museum in Berlin, the University of Chicago Oriental Institute, the University of Pennsylvania Museum of Archaeology and Anthropology, the University of Kansas Clendening History of Medicine Library, and the Prewitt–Allen Archaeological Museum of Corban University.

embargo against Cuba which prohibited the importation of Cuban products, while Cuba likewise banned the importation of American products. With Cuban-made rum unavailable in the U.S. and Coca-Cola largely unavailable in Cuba, it became difficult to make a rum and Coke with its traditional ingredients in either country. Popularity and reception The rum and Coke is very popular; Bacardi says that it is the world's second-most-popular alcoholic drink. Its popularity derives from the ubiquity and low cost of the main ingredients, and the fact that it is very easy to make. As it can be made with any quantity or style of rum, it is simple to prepare and difficult to ruin. Drink critics often have a low opinion of the cocktail. Writer Wayne Curtis called it "a drink of inspired blandness", while Jason Wilson of The Washington Post called it "a lazy person's drink". Troy Patterson of Slate called it "the classic mediocre Caribbean-American highball", which "became a classic despite not being especially good". Charles A. Coulombe considers the Cuba libre a historically important drink, writing that it is "a potent symbol of a changing world order – the marriage of rum, lubricant of the old colonial empires, and Coca-Cola, icon of modern American global capitalism". Additionally, both rum and Coca-Cola are made from Caribbean ingredients and became global commodities through European and American commerce. According to Coulombe, the drink "seems to reflect perfectly the historical elements of the modern world". Recipe and variations Recipes vary somewhat in measures and additional ingredients, but the main ingredients are always rum and cola. The International Bartenders Association recipe calls for 5 centiliters of light rum, 12 cl of cola, and 1 cl of fresh lime juice on ice. However, any amount and proportion of rum and cola may be used. Additionally, while light rum is traditional, dark rums and other varieties are also common. Coca-Cola is the conventional cola in the drink, to the point that customers rarely order anything else. This dates back to the origin of the drink in Cuba and was solidified in the 1920s when Coca-Cola emerged as the primary cola brand following the bankruptcy of Pepsi and Chero-Cola, and therefore the preferred cola mixer in alcoholic drinks. Pepsi's later attempts to enter the cocktail market were unsuccessful, especially after the song "Rum and Coca-Cola" solidified the association in the public
well as new opportunities for exporting alcohol. Light rums such as Bacardi became favored for cocktails as they were considered to mix well. Coca-Cola had been a common mixer in the United States ever since it was first bottled in 1886, and it became a ubiquitous drink in many countries after it was first exported in 1900. Rum and Coke quickly spread from Cuba to the United States. In the early 20th century the cocktail, like Coca-Cola itself, was most popular in the Southern United States. During the Prohibition era from 1922 to 1933, Coca-Cola became a favored mixer for disguising the taste of low-quality rums, as well as other liquors. In 1921 H. L. Mencken jokingly wrote of a South Carolina variant called the "jump stiddy", which consisted of Coca-Cola mixed with denatured alcohol drained from automobile radiators. After Prohibition, rum and Coke became prevalent in the northern and western U.S. as well, and in both high-brow and low-brow circles. Rum and Coke achieved a new level of popularity during World War II. Starting in 1940, the United States established a series of outposts in the British West Indies to defend against the German Navy. The American presence created cross-cultural demand, with American servicemen and the locals developing tastes for each other's products. In particular, American military personnel took to Caribbean rum due to its inexpensiveness, while Coca-Cola became especially prevalent in the islands thanks to the company shipping it out with the military. Within the United States, imported rum became increasingly popular, as government quotas for industrial alcohol reduced the output of American distillers of domestic liquors. In 1943, Lord Invader's Calypso song "Rum and Coca-Cola" drew further attention to the drink in Trinidad. The song was an adaptation of Lionel Belasco's 1904 composition "L'Année Passée" with new lyrics about American soldiers in Trinidad cavorting with local girls and drinking rum and Coke. Comedian Morey Amsterdam plagiarized "Rum and Coca-Cola" and licensed it to the Andrews Sisters as his own work. The Andrews Sisters' version was a major hit in 1945 and further boosted the popularity of rum and Coke, especially in the military. Lord Invader and the owners of Belasco's composition successfully sued Amsterdam for the song's rights. During the Cuban Revolution in 1959, Bacardi fled to Puerto Rico. The following year, the U.S. placed an embargo against Cuba which prohibited the importation of Cuban products, while Cuba likewise banned the importation of American products. With Cuban-made rum unavailable in the U.S. and Coca-Cola largely unavailable in Cuba, it became difficult to make a rum and Coke with its traditional ingredients in either country.

collagen triple helix has 3.3 residues per turn. Each of the three chains is stabilized by the steric repulsion due to the pyrrolidine rings of proline and hydroxyproline residues. The pyrrolidine rings keep out of each other's way when the polypeptide chain assumes this extended helical form, which is much more open than the tightly coiled form of the alpha helix. The three chains are hydrogen bonded to each other. The hydrogen bond donors are the peptide NH groups of glycine residues. The hydrogen bond acceptors are the CO groups of residues on the other chains. The OH group of hydroxyproline does not participate in hydrogen bonding but stabilises the trans isomer of proline by stereoelectronic effects, therefore stabilizing the entire triple helix. The rise of the collagen helix (superhelix) is 2.9 Å (0.29 nm) per residue. The center of the collagen triple helix is very small and hydrophobic, and every third residue of the helix must have contact
Due to the high abundance of glycine and proline contents, collagen fails to form a regular α-helix and β-sheet structure. Three left-handed helical strands twist to form a right-handed triple helix.

equator (as defined by rotation). This potential looks like: where is the coordinate radius, and are the test-particle's conserved energy and angular momentum respectively (constructed from the Killing vectors). To preserve cosmic censorship, the black hole is restricted to the case of . For there to exist an event horizon around the singularity, the requirement must be satisfied. This amounts to the angular momentum of the black hole being constrained to below a critical value, outside of which the horizon would disappear. The following thought experiment is reproduced from Hartle's Gravity: Problems with the concept There are a number of difficulties in formalizing the hypothesis: There are technical difficulties with properly formalizing the notion of a singularity. It is not difficult to construct spacetimes which have naked singularities, but which are not "physically reasonable"; the canonical example of such a spacetime is perhaps the "superextremal" Reissner–Nordström solution, which contains a singularity at that is not surrounded by a horizon. A formal statement needs some set of hypotheses which exclude these situations. Caustics may occur in simple models of gravitational collapse, and can appear to lead to singularities. These have more to do with the simplified models of bulk matter used, and in any case have nothing to do with general relativity, and need to be excluded. Computer models of gravitational collapse have shown that naked singularities can arise, but these models rely on very special circumstances (such as spherical symmetry). These special circumstances need to be excluded by some hypotheses. In 1991, John Preskill and Kip Thorne bet against Stephen Hawking that the hypothesis
future of a singularity. Cosmic censorship is not merely a problem of formal interest; some form of it is assumed whenever black hole event horizons are mentioned. The hypothesis was first formulated by Roger Penrose in 1969, and it is not stated in a completely formal way. In a sense it is more of a research program proposal: part of the research is to find a proper formal statement that is physically reasonable, falsifiable, and that is sufficiently general to be interesting. Because the statement is not a strictly formal one, there is sufficient latitude for (at least) two independent formulations, a weak form, and a strong form. Weak and strong cosmic censorship hypothesis The weak and the strong cosmic censorship hypotheses are two conjectures concerned with the global geometry of spacetimes. The weak cosmic censorship hypothesis asserts there can be no singularity visible from future null infinity. In other words, singularities need to be hidden from an observer at infinity by the event horizon of a black hole. Mathematically, the conjecture states that, for generic initial data, the maximal Cauchy development possesses a complete future null infinity. The strong cosmic censorship hypothesis asserts that, generically, general relativity is a deterministic theory, in the same sense that classical mechanics is a deterministic theory. In other words, the classical fate of all observers should be predictable from the initial data. Mathematically, the conjecture states that the maximal Cauchy development of generic compact or asymptotically flat initial data is locally inextendible as a regular Lorentzian manifold. This version was disproven in 2018 by Mihalis Dafermos and Jonathan Luk for the Cauchy horizon of a charged, rotating black hole. The two conjectures are mathematically independent, as there exist spacetimes for which weak cosmic censorship is valid but strong cosmic censorship is violated and, conversely, there exist spacetimes for which weak cosmic censorship is violated but strong cosmic censorship is valid. Example The Kerr metric, corresponding to a black hole of mass and angular momentum , can be used to derive the effective potential for particle orbits restricted to the equator (as defined by rotation). This potential looks like: where is the coordinate radius, and are the test-particle's conserved energy and angular momentum respectively (constructed from the Killing vectors). To preserve cosmic censorship, the black hole is restricted to the case of . For there to exist an event horizon around the singularity, the requirement must be satisfied. This amounts to the angular momentum of the black hole being constrained to below a critical value, outside of which the horizon would disappear.
