Anaximander ( ;  Anaximandros; ) was a pre-Socratic Greek philosopher who lived in Miletus, a city of Ionia (in modern-day Turkey). He belonged to the Milesian school and learned the teachings of his master Thales. He succeeded Thales and became the second master of that school where he counted Anaximenes and, arguably, Pythagoras amongst his pupils.

Little of his life and work is known today. According to available historical documents, he is the first philosopher known to have written down his studies, although only one fragment of his work remains. Fragmentary testimonies found in documents after his death provide a portrait of the man.

Anaximander was an early proponent of science and tried to observe and explain different aspects of the universe, with a particular interest in its origins, claiming that nature is ruled by laws, just like human societies, and anything that disturbs the balance of nature does not last long. Like many thinkers of his time, Anaximander's philosophy included contributions to many disciplines. In astronomy, he attempted to describe the mechanics of celestial bodies in relation to the Earth. In physics, his postulation that the indefinite (or apeiron) was the source of all things led Greek philosophy to a new level of conceptual abstraction. His knowledge of geometry allowed him to introduce the gnomon in Greece. He created a map of the world that contributed greatly to the advancement of geography. He was also involved in the politics of Miletus and was sent as a leader to one of its colonies.

Biography

Anaximander, son of Praxiades, was born in the third year of the 42nd Olympiad (610 BC). According to Apollodorus of Athens, Greek grammarian of the 2nd century BC, he was sixty-four years old during the second year of the 58th Olympiad (547–546 BC), and died shortly afterwards.

Establishing a timeline of his work is now impossible, since no document provides chronological references. Themistius, a 4th-century Byzantine rhetorician, mentions that he was the "first of the known Greeks to publish a written document on nature." Therefore, his texts would be amongst the earliest written in prose, at least in the Western world. By the time of Plato, his philosophy was almost forgotten, and Aristotle, his successor Theophrastus and a few doxographers provide us with the little information that remains. However, we know from Aristotle that Thales, also from Miletus, precedes Anaximander. It is debatable whether Thales actually was the teacher of Anaximander, but there is no doubt that Anaximander was influenced by Thales' theory that everything is derived from water. One thing that is not debatable is that even the ancient Greeks considered Anaximander to be from the Monist school which began in Miletus, with Thales followed by Anaximander and which ended with Anaximenes. 3rd-century Roman rhetorician Aelian depicts Anaximander as leader of the Milesian colony to Apollonia on the Black Sea coast, and hence some have inferred that he was a prominent citizen. Indeed, Various History (III, 17) explains that philosophers sometimes also dealt with political matters. It is very likely that leaders of Miletus sent him there as a legislator to create a constitution or simply to maintain the colony's allegiance.

Anaximander lived the final few years of his life as a subject of the Persian Achaemenid Empire.

Theories

Anaximander's theories were influenced by the Greek mythical tradition, and by some ideas of Thales – the father of Western philosophy – as well as by observations made by older civilizations in the Near East, especially Babylon. All these were developed rationally. In his desire to find some universal principle, he assumed, like traditional religion, the existence of a cosmic order; and his ideas on this used the old language of myths which ascribed divine control to various spheres of reality. This was a common practice for the Greek philosophers in a society which saw gods everywhere, and therefore could fit their ideas into a tolerably elastic system.

Some scholars see a gap between the existing mythical and the new rational way of thought which is the main characteristic of the archaic period (8th to 6th century BC) in the Greek city-states. This has given rise to the phrase "Greek miracle". But there may not have been such an abrupt break as initially appears. The basic elements of nature (water, air, fire, earth) which the first Greek philosophers believed made up the universe in fact represent the primordial forces imagined in earlier ways of thinking. Their collision produced what the mythical tradition had called cosmic harmony. In the old cosmogonies – Hesiod (8th – 7th century BC) and Pherecydes (6th century BC) – Zeus establishes his order in the world by destroying the powers which were threatening this harmony (the Titans). Anaximander claimed that the cosmic order is not monarchic but geometric, and that this causes the equilibrium of the earth, which is lying in the centre of the universe. This is the projection on nature of a new political order and a new space organized around a centre which is the static point of the system in the society as in nature. In this space there is isonomy (equal rights) and all the forces are symmetrical and transferable. The decisions are now taken by the assembly of demos in the agora which is lying in the middle of the city.

The same rational way of thought led him to introduce the abstract apeiron (indefinite, infinite, boundless, unlimited) as an origin of the universe, a concept that is probably influenced by the original Chaos (gaping void, abyss, formless state) from which everything else appeared in the mythical Greek cosmogony. It also takes notice of the mutual changes between the four elements. Origin, then, must be something else unlimited in its source, that could create without experiencing decay, so that genesis would never stop.

Apeiron

The Refutation attributed to Hippolytus of Rome (I, 5), and the later 6th century Byzantine philosopher Simplicius of Cilicia, attribute to Anaximander the earliest use of the word apeiron ( "infinite" or "limitless") to designate the original principle. He was the first philosopher to employ, in a philosophical context, the term archē (), which until then had meant beginning or origin.

"That Anaximander called this something by the name of  is the natural interpretation of what Theophrastos says; the current statement that the term  was introduced by him appears to be due to a misunderstanding."

And "Hippolytos, however, is not an independent authority, and the only question is what Theophrastos wrote."

For him, it became no longer a mere point in time, but a source that could perpetually give birth to whatever will be. The indefiniteness is spatial in early usages as in Homer (indefinite sea) and as in Xenophanes (6th century BC) who said that the earth went down indefinitely (to apeiron) i.e. beyond the imagination or concept of men.

Burnet (1930) in Early Greek Philosophy says:

"Nearly all we know of Anaximander's system is derived in the last resort from Theophrastos, who certainly knew his book. He seems once at least to have quoted Anaximander's own words, and he criticised his style. Here are the remains of what he said of him in the First Book:

"Anaximander of Miletos, son of Praxiades, a fellow-citizen and associate of Thales, said that the material cause and first element of things was the Infinite, he being the first to introduce this name of the material cause. He says it is neither water nor any other of the so-called elements, but a substance different from them which is infinite" [apeiron, or ] "from which arise all the heavens and the worlds within them.—Phys, Op. fr. 2 (Dox. p. 476; R. P. 16)."

Burnet's quote from the "First Book" is his translation of Theophrastos' Physic Opinion fragment 2 as it appears in p. 476 of Historia Philosophiae Graecae (1898) by Ritter and Preller and section 16 of Doxographi Graeci (1879) by Diels.

By ascribing the "Infinite" with a "material cause", Theophrastos is following the Aristotelian tradition of "nearly always discussing the facts from the point of view of his own system".

Aristotle writes (Metaphysics, I.III 3–4) that the Pre-Socratics were searching for the element that constitutes all things. While each pre-Socratic philosopher gave a different answer as to the identity of this element (water for Thales and air for Anaximenes), Anaximander understood the beginning or first principle to be an endless, unlimited primordial mass (apeiron), subject to neither old age nor decay, that perpetually yielded fresh materials from which everything we perceive is derived. He proposed the theory of the apeiron in direct response to the earlier theory of his teacher, Thales, who had claimed that the primary substance was water. The notion of temporal infinity was familiar to the Greek mind from remote antiquity in the religious concept of immortality, and Anaximander's description was in terms appropriate to this conception. This archē is called "eternal and ageless". (Hippolytus (?), Refutation, I,6,I;DK B2)

"Aristotle puts things in his own way regardless of historical considerations, and it is difficult to see that it is more of an anachronism to call the Boundless " intermediate between the elements " than to say that it is " distinct from the elements." Indeed, if once we introduce the elements at all, the former description is the more adequate of the two. At any rate, if we refuse to understand these passages as referring to Anaximander, we shall have to say that Aristotle paid a great deal of attention to some one whose very name has been lost, and who not only agreed with some of Anaximander's views, but also used some of his most characteristic expressions. We may add that in one or two places Aristotle certainly seems to identify the " intermediate " with the something " distinct from " the elements."

"It is certain that he [Anaximander] cannot have said anything about elements, which no one thought of before Empedokles, and no one could think of before Parmenides. The question has only been mentioned because it has given rise to a lengthy controversy, and because it throws light on the historical value of Aristotle's statements. From the point of view of his own system, these may be justified; but we shall have to remember in other cases that, when he seems to attribute an idea to some earlier thinker, we are not bound to take what he says in an historical sense."

For Anaximander, the principle of things, the constituent of all substances, is nothing determined and not an element such as water in Thales' view. Neither is it something halfway between air and water, or between air and fire, thicker than air and fire, or more subtle than water and earth. Anaximander argues that water cannot embrace all of the opposites found in nature — for example, water can only be wet, never dry — and therefore cannot be the one primary substance; nor could any of the other candidates. He postulated the apeiron as a substance that, although not directly perceptible to us, could explain the opposites he saw around him.

"If Thales had been right in saying that water was the fundamental reality, it would not be easy to see how anything else could ever have existed. One side of the opposition, the cold and moist, would have had its way unchecked, and the warm and dry would have been driven from the field long ago. We must, then, have something not itself one of the warring opposites, something more primitive, out of which they arise, and into which they once more pass away."

Anaximander explains how the four elements of ancient physics (air, earth, water and fire) are formed, and how Earth and terrestrial beings are formed through their interactions. Unlike other Pre-Socratics, he never defines this principle precisely, and it has generally been understood (e.g., by Aristotle and by Saint Augustine) as a sort of primal chaos. According to him, the Universe originates in the separation of opposites in the primordial matter. It embraces the opposites of hot and cold, wet and dry, and directs the movement of things; an entire host of shapes and differences then grow that are found in "all the worlds" (for he believed there were many).

"Anaximander taught, then, that there was an eternal. The indestructible something out of which everything arises, and into which everything returns; a boundless stock from which the waste of existence is continually made good, "elements.". That is only the natural development of the thought we have ascribed to Thales, and there can be no doubt that Anaximander at least formulated it distinctly. Indeed, we can still follow to some extent the reasoning which led him to do so. Thales had regarded water as the most likely thing to be that of which all others are forms; Anaximander appears to have asked how the primary substance could be one of these particular things. His argument seems to be preserved by Aristotle, who has the following passage in his discussion of the Infinite: "Further, there cannot be a single, simple body which is infinite, either, as some hold, one distinct from the elements, which they then derive from it, or without this qualification. For there are some who make this. (i.e. a body distinct from the elements). the infinite, and not air or water, in order that the other things may not be destroyed by their infinity. They are in opposition one to another. air is cold, water moist, and fire hot. and therefore, if any one of them were infinite, the rest would have ceased to be by this time. Accordingly they say that what is infinite is something other than the elements, and from it the elements arise.'—Aristotle Physics. F, 5 204 b 22 (Ritter and Preller (1898) Historia Philosophiae Graecae, section 16 b)."

Anaximander maintains that all dying things are returning to the element from which they came (apeiron). The one surviving fragment of Anaximander's writing deals with this matter. Simplicius transmitted it as a quotation, which describes the balanced and mutual changes of the elements:

Whence things have their origin,
Thence also their destruction happens,
According to necessity;
For they give to each other justice and recompense
For their injustice
In conformity with the ordinance of Time.

Simplicius mentions that Anaximander said all these "in poetic terms", meaning that he used the old mythical language. The goddess Justice (Dike) keeps the cosmic order. This concept of returning to the element of origin was often revisited afterwards, notably by Aristotle, and by the Greek tragedian Euripides: "what comes from earth must return to earth." Friedrich Nietzsche, in his Philosophy in the Tragic Age of the Greeks, stated that Anaximander viewed "... all coming-to-be as though it were an illegitimate emancipation from eternal being, a wrong for which destruction is the only penance." Physicist Max Born, in commenting upon Werner Heisenberg's arriving at the idea that the elementary particles of quantum mechanics are to be seen as different manifestations, different quantum states, of one and the same "primordial substance,"' proposed that this primordial substance be called apeiron.

A free-floating Earth

Anaximander was the first to conceive a mechanical model of the world. In his model, the Earth floats very still in the centre of the infinite, not supported by anything. It remains "in the same place because of its indifference", a point of view that Aristotle considered ingenious, in On the Heavens. Its curious shape is that of a cylinder with a height one-third of its diameter. The flat top forms the inhabited world, which is surrounded by a circular oceanic mass.

Carlo Rovelli suggests that Anaximander took the idea of the Earth's shape as a floating disk from Thales, who had imagined the Earth floating in water, the "immense ocean from which everything is born and upon which the Earth floats." Anaximander was then able to envisage the Earth at the centre of an infinite space, in which case it required no support as there was nowhere "down" to fall. In Rovelli's view, the shape – a cylinder or a sphere – is unimportant compared to the appreciation of a "finite body that floats free in space."

Anaximander's realization that the Earth floats free without falling and does not need to be resting on something has been indicated by many as the first cosmological revolution and the starting point of scientific thinking. Karl Popper calls this idea "one of the boldest, most revolutionary, and most portentous ideas in the whole history of human thinking." Such a model allowed the concept that celestial bodies could pass under the Earth, opening the way to Greek astronomy. Rovelli suggests that seeing the stars circling the Pole star, and both vanishing below the horizon on one side and reappearing above it on the other, would suggest to the astronomer that there was a void both above and below the Earth.

Cosmology

Anaximander's bold use of non-mythological explanatory hypotheses considerably distinguishes him from previous cosmology writers such as Hesiod. It indicates a pre-Socratic effort to demystify physical processes. His major contribution to history was writing the oldest prose document about the Universe and the origins of life; for this he is often called the "Father of Cosmology" and founder of astronomy. However, pseudo-Plutarch states that he still viewed celestial bodies as deities. He placed the celestial bodies in the wrong order. He thought that the stars were nearest to the earth, then the moon, and the sun farthest away. His scheme is compatible with the Indo-Iranian philosophical traditions contained in the Iranian Avesta och the Indian Upanishads.

At the origin, after the separation of hot and cold, a ball of flame appeared that surrounded Earth like bark on a tree. This ball broke apart to form the rest of the Universe. It resembled a system of hollow concentric wheels, filled with fire, with the rims pierced by holes like those of a flute. Consequently, the Sun was the fire that one could see through a hole the same size as the Earth on the farthest wheel, and an eclipse corresponded with the occlusion of that hole. The diameter of the solar wheel was twenty-seven times that of the Earth (or twenty-eight, depending on the sources) and the lunar wheel, whose fire was less intense, eighteen (or nineteen) times. Its hole could change shape, thus explaining lunar phases. The stars and the planets, located closer, followed the same model.

Anaximander was the first astronomer to consider the Sun as a huge mass, and consequently, to realize how far from Earth it might be, and the first to present a system where the celestial bodies turned at different distances. Furthermore, according to Diogenes Laertius (II, 2), he built a celestial sphere. This invention undoubtedly made him the first to realize the obliquity of the Zodiac as the Roman philosopher Pliny the Elder reports in Natural History (II, 8). It is a little early to use the term ecliptic, but his knowledge and work on astronomy confirm that he must have observed the inclination of the celestial sphere in relation to the plane of the Earth to explain the seasons. The doxographer and theologian Aetius attributes to Pythagoras the exact measurement of the obliquity.

Multiple worlds

According to Simplicius, Anaximander already speculated on the plurality of worlds, similar to atomists Leucippus and Democritus, and later philosopher Epicurus. These thinkers supposed that worlds appeared and disappeared for a while, and that some were born when others perished. They claimed that this movement was eternal, "for without movement, there can be no generation, no destruction".

In addition to Simplicius, Hippolytus reports Anaximander's claim that from the infinite comes the principle of beings, which themselves come from the heavens and the worlds (several doxographers use the plural when this philosopher is referring to the worlds within, which are often infinite in quantity). Cicero writes that he attributes different gods to the countless worlds.

This theory places Anaximander close to the Atomists and the Epicureans who, more than a century later, also claimed that an infinity of worlds appeared and disappeared. In the timeline of the Greek history of thought, some thinkers conceptualized a single world (Plato, Aristotle, Anaxagoras and Archelaus), while others instead speculated on the existence of a series of worlds, continuous or non-continuous (Anaximenes, Heraclitus, Empedocles and Diogenes).

Meteorological phenomena

Anaximander attributed some phenomena, such as thunder and lightning, to the intervention of elements, rather than to divine causes. In his system, thunder results from the shock of clouds hitting each other; the loudness of the sound is proportionate with that of the shock. Thunder without lightning is the result of the wind being too weak to emit any flame, but strong enough to produce a sound. A flash of lightning without thunder is a jolt of the air that disperses and falls, allowing a less active fire to break free. Thunderbolts are the result of a thicker and more violent air flow.

He saw the sea as a remnant of the mass of humidity that once surrounded Earth. A part of that mass evaporated under the sun's action, thus causing the winds and even the rotation of the celestial bodies, which he believed were attracted to places where water is more abundant. He explained rain as a product of the humidity pumped up from Earth by the sun. For him, the Earth was slowly drying up and water only remained in the deepest regions, which someday would go dry as well. According to Aristotle's Meteorology (II, 3), Democritus also shared this opinion.

Origin of mankind

Anaximander speculated about the beginnings and origin of animal life, and that humans came from other animals in waters. According to his evolutionary theory, animals sprang out of the sea long ago, born trapped in a spiny bark, but as they got older, the bark would dry up and animals would be able to break it. As the early humidity evaporated, dry land emerged and, in time, humankind had to adapt. The 3rd century Roman writer Censorinus reports:

Anaximander put forward the idea that humans had to spend part of this transition inside the mouths of big fish to protect themselves from the Earth's climate until they could come out in open air and lose their scales. He thought that, considering humans' extended infancy, we could not have survived in the primeval world in the same manner we do presently.

Other accomplishments

Cartography

Both Strabo and Agathemerus (later Greek geographers) claim that, according to the geographer Eratosthenes, Anaximander was the first to publish a map of the world. The map probably inspired the Greek historian Hecataeus of Miletus to draw a more accurate version. Strabo viewed both as the first geographers after Homer.

Maps were produced in ancient times, also notably in Egypt, Lydia, the Middle East, and Babylon. Only some small examples survived until today. The unique example of a world map comes from the late Babylonian Map of the World later than 9th century BC but is based probably on a much older map. These maps indicated directions, roads, towns, borders, and geological features. Anaximander's innovation was to represent the entire inhabited land known to the ancient Greeks.

Such an accomplishment is more significant than it at first appears. Anaximander most likely drew this map for three reasons. First, it could be used to improve navigation and trade between Miletus's colonies and other colonies around the Mediterranean Sea and Black Sea. Second, Thales would probably have found it easier to convince the Ionian city-states to join in a federation in order to push the Median threat away if he possessed such a tool. Finally, the philosophical idea of a global representation of the world simply for the sake of knowledge was reason enough to design one.

Surely aware of the sea's convexity, he may have designed his map on a slightly rounded metal surface. The centre or "navel" of the world ( omphalós gẽs) could have been Delphi, but is more likely in Anaximander's time to have been located near Miletus. The Aegean Sea was near the map's centre and enclosed by three continents, themselves located in the middle of the ocean and isolated like islands by sea and rivers. Europe was bordered on the south by the Mediterranean Sea and was separated from Asia by the Black Sea, the Lake Maeotis, and, further east, either by the Phasis River (now called the Rioni in Georgia) or the Tanais. The Nile flowed south into the ocean, separating Libya (which was the name for the part of the then-known African continent) from Asia.

Gnomon

The Suda relates that Anaximander explained some basic notions of geometry. It also mentions his interest in the measurement of time and associates him with the introduction in Greece of the gnomon. In Lacedaemon, he participated in the construction, or at least in the adjustment, of sundials to indicate solstices and equinoxes. Indeed, a gnomon required adjustments from a place to another because of the difference in latitude.

In his time, the gnomon was simply a vertical pillar or rod mounted on a horizontal plane. The position of its shadow on the plane indicated the time of day. As it moves through its apparent course, the Sun draws a curve with the tip of the projected shadow, which is shortest at noon, when pointing due south. The variation in the tip's position at noon indicates the solar time and the seasons; the shadow is longest on the winter solstice and shortest on the summer solstice.

The invention of the gnomon itself cannot be attributed to Anaximander because its use, as well as the division of days into twelve parts, came from the Babylonians. It is they, according to Herodotus' Histories (II, 109), who gave the Greeks the art of time measurement. It is likely that he was not the first to determine the solstices, because no calculation is necessary. On the other hand, equinoxes do not correspond to the middle point between the positions during solstices, as the Babylonians thought. As the Suda seems to suggest, it is very likely that with his knowledge of geometry, he became the first Greek to determine accurately the equinoxes.

Prediction of an earthquake

In his philosophical work De Divinatione (I, 50, 112), Cicero states that Anaximander convinced the inhabitants of Lacedaemon to abandon their city and spend the night in the country with their weapons because an earthquake was near. The city collapsed when the top of the Taygetus split like the stern of a ship. Pliny the Elder also mentions this anecdote (II, 81), suggesting that it came from an "admirable inspiration", as opposed to Cicero, who did not associate the prediction with divination.

Scientific method

Rovelli credits Anaximander with pioneering the "first great scientific revolution in history" by introducing the naturalistic approach to understanding the universe, according to which the universe operates by inviolable laws, without recourse to supernatural explanations. According to Rovelli, Anaximander not only paved the way for modern science, but revolutionized the process for how we form our worldview, by constantly questioning and rejecting certainty. Rovelli further states that Anaximander has not been given his due credit, largely because his naturalistic approach was strongly opposed in antiquity (among others by Aristotle) and had yet to yield the tangible benefits it has today.

Legacy

In the 2017 essay collection Anaximander in Context: New Studies on the Origins of Greek Philosophy, Dirk Couprie, Robert Hahn and Gerald Naddaf describe Anaximander as "one of the greatest minds in history", but one that has not been given his due. Couprie goes to state that he considers him on par with Newton.

Bertrand Russell in the History of Western Philosophy interprets Anaximander's theories as  an assertion of the necessity of an appropriate balance between earth, fire, and water, all of which may be independently seeking to aggrandize their proportions relative to the others. Anaximander seems to express his belief that a natural order ensures balance among these elements, that where there was fire, ashes (earth) now exist. His Greek peers echoed this sentiment with their belief in natural boundaries beyond which not even the gods could operate.

Friedrich Nietzsche, in Philosophy in the Tragic Age of the Greeks, claimed that Anaximander was a pessimist who asserted that the primal being of the world was a state of indefiniteness. In accordance with this, anything definite has to eventually pass back into indefiniteness. In other words, Anaximander viewed "...all coming-to-be as though it were an illegitimate emancipation from eternal being, a wrong for which destruction is the only penance". (Ibid., § 4) The world of individual objects, in this way of thinking, has no worth and should perish.

Martin Heidegger lectured extensively on Anaximander, and delivered a lecture entitled "Anaximander's Saying" which was subsequently included in Off the Beaten Track. The lecture examines the ontological difference and the oblivion of Being or Dasein in the context of the Anaximander fragment. Heidegger's lecture is, in turn, an important influence on the French philosopher Jacques Derrida.

The Anaximander (31st) High School of Thessaloniki, Greece is named after Anaximander.

Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids.
A recent study conducted in the Cosmics Leaving Outdoor Droplets large cloud chamber at CERN, has identified sesquiterpenes — gaseous hydrocarbons that are released by plants — as potentially playing a major role in cloud formation in relatively pristine regions of the atmosphere.

Biosynthesis and examples
The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene.

Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can lead to macrocyclic rings such as humulene.

The cadinenes contain two fused six-membered rings. Caryophyllene, a component of many essential oils such as clove oil, contains a nine-membered ring fused to a cyclobutane ring. Rishitin is another example of a cadinene, which is found in potatoes and tomatoes.

Vetivazulene and guaiazulene are aromatic bicyclic sesquiterpenoids.

With the addition of a third ring, the possible structures become increasingly varied. Examples include longifolene, copaene and the alcohol patchoulol.

Sesquiterpenoids
The FPP backbone can be rearranged in several different ways and further decorated with different functional groups, hence the large variety of sesquiterpenoids. Geosmin, the volatile compound that gives an earthy taste and musty odor in drinking water and the characteristic odor on a rainy day, is a sesquiterpenoid, produced by bacteria, especially cyanobacteria, that are present in the soils and water supplies. Oxidation of farnesene then provides the sesquiterpenoid farnesol.

Sesquiterpene lactones are a common class of sesquiterpenoids that contain a lactone ring, hence the name. They are found in many plants and can cause allergic reactions and toxicity if consumed excessively, particularly in grazing livestock.

The term merosesquiterpenoids was coined in 1968 to describe molecules of this class that have a mixed biosynthetic origin, meaning isoprenoid precursors like isopentenyl pyrophosphate are derived from both the mevalonate and non-mevalonate pathways.

Gandon answered an advertisement in a paper and finally obtained the right to design "Femme indigène", his first postage stamp series issued 1941 in the French colony of Dahomey.

The same year was issued his first stamp for France : the coat of arms of Reims.

In 1941, during the Second World War, with Luigi Corbellini, Gérard Cochet, and others Gandon was one of the painters and sculptors who received the higher rate of 10,000 Francs from the City of Paris to compensate artists and intellectuals for loss of income.

Four times he received the Grand Prix de l'Art philatélique during his career that including:

 « Haute couture parisienne» (Paris high sewing), drawn by Gandon, engraved by Jules Piel, France, 1953.

 « La jeune fille de Bora Bora » (The Girl of Bora Bora), Drawn and Engraved by Gandon, French Polynesia, 1955.

 « Les joueurs de cartes » (Card Players), painting by Paul Cézanne, France, 1961. This stamp was part of the first series of paintings that the French Post issued.

 « La Dame à la licorne » (The Lady and the Unicorn), medieval tapestry, France, 1964.

Among the most famous stamps designed and engraved by Gandon are two series of female allegories in common use of the 1940s, 1970s and 1980s:

three French definitive stamps series :

 Marianne de Gandon series issued at the end of the Second World War,
 Sabine de Gandon series inspired by Jacques-Louis David's The Intervention of the Sabine Women, issued during the 1970s,
 and Liberté de Gandon series inspired by Eugène Delacroix's Liberty Leading the People. He was 82 years old when he engraved this stamp.

His last stamp was issued for the Journée du timbre 1983.

In total, Pierre Gandon designed and/or engraved over 350 stamps for France  and over double that number for the French Colonies. He designed the first stamps issued by the Central African Republic in December 1959.

Dubbing, mixing or re-recording, is a post-production process used in filmmaking and video production. This is in which more recordings are lip-synced and "mixed" with original production sound to create the finished soundtrack. It is mainly used to translate works in other languages.

These are often used to translate movies, television shows and video games into different languages using different voice actors.

AIM (AOL Instant Messenger) was an instant messaging and presence computer program created by AOL, which used the proprietary OSCAR instant messaging protocol and the TOC protocol to allow registered users to communicate in real time.

AIM was popular by the late 1990s, in United States and other countries, and was the leading instant messaging application in that region into the following decade. Teens and college students were known to use the messenger's away message feature to keep in touch with friends, often frequently changing their away message throughout a day or leaving a message up with one's computer left on to inform buddies of their ongoings, location, parties, thoughts, or jokes. AIM's popularity declined as AOL subscribers started decreasing and steeply towards the 2010s, as Gmail's Google Talk, SMS, and Internet social networks, like Facebook gained popularity. Its fall has often been compared with other once-popular Internet services, such as Myspace.

In June 2015, AOL was acquired by Verizon Communications. In June 2017, Verizon combined AOL and Yahoo into its subsidiary Oath Inc. (now called Yahoo). The company discontinued AIM as a service on December 15, 2017.

History
In May 1997, AIM was released unceremoniously as a stand-alone download for Microsoft Windows. AIM was an outgrowth of "online messages" in the original platform written in PL/1 on a Stratus computer by Dave Brown. At one time, the software had the largest share of the instant messaging market in North America, especially in the United States (with 52% of the total reported ). This does not include other instant messaging software related to or developed by AOL, such as ICQ and iChat.

During its heyday, its main competitors were ICQ (which AOL acquired in 1998), Yahoo! Messenger and MSN Messenger. AOL particularly had a rivalry or "chat war" with PowWow and Microsoft, starting in 1999. There were several attempts from Microsoft to simultaneously log into their own and AIM's protocol servers. AOL was unhappy about this and started blocking MSN Messenger from being able to access AIM. This led to efforts by many companies to challenge the AOL and Time Warner merger on the grounds of antitrust behaviour, leading to the formation of the OpenNet Coalition.

Official mobile versions of AIM appeared as early as 2001 on Palm OS through the AOL application. Third-party applications allowed it to be used in 2002 for the Sidekick. A version for Symbian OS was announced in 2003 as were others for BlackBerry and Windows Mobile

After 2012, stand-alone official AIM client software included advertisements and was available for Microsoft Windows, Windows Mobile, Classic Mac OS, macOS, Android, iOS, and BlackBerry OS.

Usage decline and product sunset
Around 2011, AIM started to lose popularity rapidly, partly due to the quick rise of Gmail and its built-in real-time Google Chat instant messenger integration in 2011 and because many people migrated to SMS or iMessages text messaging and later, social networking websites and apps for instant messaging, in particular, Facebook Messenger, which was released as a standalone application the same year. AOL made a partnership to integrate AIM messaging in Google Talk, and had a feature for AIM users to send SMS messages directly from AIM to any number, as well as for SMS users to send an IM to any AIM user.

As of June 2011, one source reported AOL Instant Messenger market share had collapsed to 0.73%. However, this number only reflected installed IM applications, and not active users. The engineers responsible for AIM claimed that they were unable to convince AOL management that free was the future.

On March 3, 2012, AOL ended employment of AIM's development staff while leaving it active and with help support still provided. On October 6, 2017, it was announced that the AIM service would be discontinued on December 15; however, a non-profit development team known as Wildman Productions started up a server for older versions of AOL Instant Messenger, known as AIM Phoenix.

The "AIM Man"

The AIM mascot was designed by JoRoan Lazaro and was implemented in the first release in 1997. This was a yellow stickman-like figure, often called the "Running Man". The mascot appeared on all AIM logos and most wordmarks, and always appeared at the top of the buddy list. AIM's popularity in the late 1990s and the 2000s led to the "Running Man" becoming a familiar brand on the Internet. After over 14 years, the iconic logo disappeared as part of the AIM rebranding in 2011. However, in August 2013, the "Running Man" returned. It was used for other AOL services like AOL Top Speed.

In 2014, a Complex editor called it a "symbol of America". In April 2015, the Running Man was officially featured in the Virgin London Marathon, dressed by a person for the AOL-partnered Free The Children charity.

Protocol
The standard protocol that AIM clients used to communicate is called Open System for CommunicAtion in Realtime (OSCAR). Most AOL-produced versions of AIM and popular third party AIM clients use this protocol. However, AOL also created a simpler protocol called TOC that lacks many of OSCAR's features, but was sometimes used for clients that only require basic chat functionality. The TOC/TOC2 protocol specifications were made available by AOL, while OSCAR is a closed protocol that third parties had to reverse-engineer.

In January 2008, AOL introduced experimental Extensible Messaging and Presence Protocol (XMPP) support for AIM, allowing AIM users to communicate using the standardized, open-source XMPP. However, in March 2008, this service was discontinued. In May 2011, AOL started offering limited XMPP support. On March 1, 2017, AOL announced (via XMPP-login-time messages) that the AOL XMPP gateway would be desupported, effective March 28, 2017.

Privacy
For privacy regulations, AIM had strict age restrictions. AIM accounts are available only for people over the age of 13; children younger than that were not permitted access to AIM.

Under the AIM Privacy Policy, AOL had no rights to read or monitor any private communications between users. The profile of the user had no privacy.

In November 2002, AOL targeted the corporate industry with Enterprise AIM Services (EAS), a higher security version of AIM.

If public content was accessed, it could be used for online, print or broadcast advertising, etc. This was outlined in the policy and terms of service: "... you grant AOL, its parent, affiliates, subsidiaries, assigns, agents and licensees the irrevocable, perpetual, worldwide right to reproduce, display, perform, distribute, adapt and promote this Content in any medium". This allowed anything users posted to be used without a separate request for permission.

AIM's security was called into question. AOL stated that it had taken great pains to ensure that personal information will not be accessed by unauthorized members, but that it cannot guarantee that it will not happen.

AIM was different from other clients, such as Yahoo! Messenger, in that it did not require approval from users to be added to other users' buddy lists. As a result, it was possible for users to keep other unsuspecting users on their buddy list to see when they were online, read their status and away messages, and read their profiles. There was also a Web API to display one's status and away message as a widget on one's webpage. Though one could block a user from communicating with them and seeing their status, this did not prevent that user from creating a new account that would not automatically be blocked and therefore able to track their status. A more conservative privacy option was to select a menu feature that only allowed communication with users on one's buddy list; however, this option also created the side-effect of blocking all users who were not on one's buddy list. Users could also choose to be invisible to all.

Chat robots
AOL and various other companies supplied robots (bots) on AIM that could receive messages and send a response based on the bot's purpose. For example, bots could help with studying, like StudyBuddy. Some were made to relate to children and teenagers, like Spleak.

Others gave advice. The more useful chat bots had features like the ability to play games, get sport scores, weather forecasts or financial stock information. Users were able to talk to automated chat bots that could respond to natural human language. They were primarily put into place as a marketing strategy and for unique advertising options. It was used by advertisers to market products or build better consumer relations.

Before the inclusions of such bots, the other bots DoorManBot and AIMOffline provided features that were provided by AOL for those who needed it. ZolaOnAOL and ZoeOnAOL were short-lived bots that ultimately retired their features in favor of SmarterChild.

URI scheme
AOL Instant Messenger's installation process automatically installed an extra URI scheme ("protocol") handler into some Web browsers, so URIs beginning "aim:" could open a new AIM window with specified parameters. This was similar in function to the mailto: URI scheme, which created a new e-mail message using the system's default mail program. For instance, a webpage might have included a link like the following in its HTML source to open a window for sending a message to the AIM user notarealuser:
 Send Message

To specify a message body, the message parameter was used, so the link location would have looked like this:
 aim:goim?screenname=notarealuser&message=This+is+my+message

To specify an away message, the message parameter was used, so the link location would have looked like this:
 aim:goaway?message=Hello,+my+name+is+Bill
When placing this inside a URL link, an AIM user could click on the URL link and the away message "Hello, my name is Bill" would instantly become their away message.

To add a buddy, the addbuddy message was used, with the "screenname" parameter
 aim:addbuddy?screenname=notarealuser
This type of link was commonly found on forum profiles to easily add contacts.

Vulnerabilities
AIM had security weaknesses that have enabled exploits to be created that used third-party software to perform malicious acts on users' computers. Although most were relatively harmless, such as being kicked off the AIM service, others performed potentially dangerous actions, such as sending viruses. Some of these exploits relied on social engineering to spread by automatically sending instant messages that contained a Uniform Resource Locator (URL) accompanied by text suggesting the receiving user click on it, an action which leads to infection, i.e., a trojan horse. These messages could easily be mistaken as coming from a friend and contain a link to a Web address that installed software on the user's computer to restart the cycle.

Users also have reported sudden additions of toolbars and advertisements from third parties in the newer version of AIM. Multiple complaints about the lack of control of third party involvement have caused many users to stop using the service.

Extra features

iPhone application
On March 6, 2008, during Apple Inc.'s iPhone SDK event, AOL announced that they would be releasing an AIM application for iPhone and iPod Touch users. The application was available for free from the App Store, but the company also provides a paid version, which displays no advertisements. Both were available from the App Store. The AIM client for iPhone and iPod Touch supported standard AIM accounts, as well as MobileMe accounts. There was also an express version of AIM accessible through the Safari browser on the iPhone and iPod Touch.

In 2011, AOL launched an overhaul of their Instant Messaging service. Included in the update was a brand new iOS application for iPhone and iPod Touch that incorporated all the latest features. A brand new icon was used for the application, featuring the new cursive logo for AIM. The user-interface was entirely redone for the features including: a new buddy list, group messaging, in-line photos and videos, as well as improved file-sharing.

Version 5.0.5, updated in March 2012, it supported more social stream features, much like Facebook and Twitter, as well as the ability to send voice messages up to 60 seconds long.

iPad application
On April 3, 2010, Apple released the first generation iPad. Along with this newly released device AOL released the AIM application for iPad. It was built entirely from scratch for the new version iOS with a specialized user-interface for the device. It supports geo location, Facebook status updates and chat, Myspace, Twitter, YouTube, Foursquare and many social networking platforms.

AIM Express
AIM Express ran in a pop-up browser window. It was intended for use by people who are unwilling or unable to install a standalone application or those at computers that lack the AIM application. AIM Express supported many of the standard features included in the stand-alone client, but did not provide advanced features like file transfer, audio chat, video conferencing, or buddy info. It was implemented in Adobe Flash. It was an upgrade to the prior AOL Quick Buddy, which was later available for older systems that cannot handle Express before being discontinued. Express and Quick Buddy were similar to MSN Web Messenger and Yahoo! Web Messenger. This web version evolved into AIM.com's web-based messenger.

AIM Pages
AIM Pages was a free website released in May 2006 by AOL in replacement of AIMSpace. Anyone who had an AIM user name and was at least 16 years of age could create their own web page (to display an online, dynamic profile) and share it with buddies from their AIM Buddy list.

Layout
AIM Pages included links to the email and Instant Message of the owner, along with a section listing the owners "buddies", which included AIM user names. It was possible to create modules in a Module T microformat. Video hosting sites like Netflix and YouTube could be added to ones AIM Page, as well as other sites like Amazon.com. It was also possible to insert HTML code.

The main focus of AIM Pages was the integration of external modules, like those listed above, into the AOL Instant Messenger experience.

Discontinuation
By late 2007, AIM Pages had been discontinued. After AIM Pages shutdown, links to AIM Pages were redirected to AOL Lifestream, AOL's new site aimed at collecting external modules in one place, independent of AIM buddies. AOL Lifestream was shut down February 24, 2017.

AIM for Mac
AOL released an all-new AIM for the Mac on September 29, 2008, and the final build on December 15, 2008. The redesigned AIM for Mac is a full universal binary Cocoa API application that supports both Tiger and Leopard — Mac OS X 10.4.8 (and above) or Mac OS X 10.5.3 (and above). On October 1, 2009, AOL released AIM 2.0 for Mac.

AIM real-time IM
This feature is available for AIM 7 and allows for a user to see what the other is typing as it is being done. It was developed and built with assistance from Trace Research and Development Centre at University of Wisconsin–Madison and Gallaudet University. The application provides visually impaired users the ability to convert messages from text (words) to speech. For the application to work users must have AIM 6.8 or higher, as it is not compatible with older versions of AIM software, AIM for Mac or iChat.

AIM to mobile (messaging to phone numbers)
This feature allows text messaging to a phone number (text messaging is less functional than instant messaging).

Discontinued features

AIM Phoneline
AIM Phoneline was a Voice over IP PC-PC, PC-Phone and Phone-to-PC service provided via the AIM application. It was also known to work with Apple's iChat Client. The service was officially closed to its customers on January 13, 2009. The closing of the free service caused the number associated with the service to be disabled and not transferable for a different service. AIM Phoneline website was recommending users switch to a new service named AIM Call Out, also discontinued now.

Launched on May 16, 2006, AIM Phoneline provided users the ability to have several local numbers, allowing AIM users to receive free incoming calls. The service allowed users to make calls to landlines and mobile devices through the use of a computer. The service, however, was only free for receiving and AOL charged users $14.95 a month for an unlimited calling plan. In order to use AIM Phoneline users had to install the latest free version of AIM Triton software and needed a good set of headphones with a boom microphone. It could take several days after a user signed up before it started working.

AIM Call Out
AIM Call Out is a discontinued Voice over IP PC-PC, PC-Phone and Phone-to-PC service provided by AOL via its AIM application that replaced the defunct AIM Phoneline service in November 2007. It did not depend on the AIM client and could be used with only an AIM screenname via the WebConnect feature or a dedicated SIP device. The AIM Call Out service was shut down on March 25, 2009.

Security
On November 4, 2014, AIM scored one out of seven points on the Electronic Frontier Foundation's secure messaging scorecard. AIM received a point for encryption during transit, but lost points because communications are not encrypted with a key to which the provider has no access, i.e., the communications are not end-to-end encrypted, users can't verify contacts' identities, past messages are not secure if the encryption keys are stolen, (i.e., the service does not provide forward secrecy), the code is not open to independent review, i.e., the code is not open-source), the security design is not properly documented, and there has not been a recent independent security audit. BlackBerry Messenger, Ebuddy XMS, Hushmail, Kik Messenger, Skype, Viber, and Yahoo! Messenger also scored one out of seven points.

Samuel Joseph Marata (born June 28, 1991) is a Filipino former professional basketball player. He last played for the Pilipinas MX3 Kings of the ASEAN Basketball League. He was selected 25th overall in the 2013 PBA draft by the Petron Blaze Boosters.

College / amateur career
Marata initially attended at Reedley International School, but later on, he transferred to University of the Philippines Integrated School (UPIS), where he became a standout and was awarded as the UAAP Season 70 Juniors MVP. After his high school career ended, he was recruited by DLSU but had to sit out for a year owing to UAAP's residency rules for student-athlete transferring from one UAAP member school to another. After serving his one-year residency, he made the Green Archers' line up for UAAP Season 72. He had his most fruitful outing as a Green Archer during his sophomore year, he averaged 7.3 points, 1.4 assists, and 25% shooting percentage from the three-point area in 16 minutes of play, while establishing himself as a reliable outside shooter. His numbers, however, saw a dip the following year. In UAAP Season 74, he averaged just five points and a 15% outside shooting clip in 17 minutes of play. He failed to make the team's line up for Season 75, citing academic problems. He decided to leave La Salle and returned to his high school alma mater at UP. After fulfilling his residency requirements, he made it to the Fighting Maroons' lineup for Season 76.

While in college, he played for the Blackwater Sports in the PBA Developmental League.

Professional career
