1. Democritus Of Abdera
An short introduction to this ancient atomistic thinker.
http://www.geocities.com/lucretius5978/biography/democritus.html

Extractions: Democritus was born in the city of Abdera which is located in the region of Greece known as Ionia. He and his teacher Leucippus ( LeukippoV ) are believed to have developed the atomic theory which turned out to be strikingly accurate in a sense. In his theory, he postulated the existance of particles called " Atomos " or Atomos which is a Greek word meaning "indivisible". While the particles which are now named after this word, atoms, are certainly not indivisible, energy can be emitted or absorbed only in discrete units called quanta. The field of physics that describes this quantification of energy is appropriately named quantum mechanics. Since the energy never exists at a state in between these quanta, these energy quanta are like the atoms of Democritus in that they are indivisible. He wrote extensively on many subjects, but few of his works remain. He also made many contributions to mathematics which, had they not been lost, may have led to the development of calculus more than a millenium earlier than the time of Sir Isaac Newton. Some of these are on the subjects of numbers, geometry, mappings, irrational numbers, and perhaps most importantly, tangencies. It was the problem in mathematics known as the tangent line problem which led to the development of the most fundamental ideas in calculus. With calculus you can find the slope of a curved line at any point (being curved, it is different at every point) with a process called differentiation. This is done by finding the slope of the tangent line to the curve at that point (A tangent line is a line that meets that curve at exactly one point without crossing it.) using secant lines (crossing the curve at two points) to successively approximate the tangent line.

Extractions: Democritus of Abdera is best known for his atomic theory but he was also an excellent geometer. Very little is known of his life but we know that Leucippus was his teacher. Democritus certainly visited Athens when he was a young man, principally to visit Anaxagoras , but Democritus complained how little he was known there. He said, according to Diogenes Laertius writing in the second century AD [5]:- I came to Athens and no one knew me. Democritus was disappointed by his trip to Athens because Anaxagoras , then an old man, had refused to see him. As Brumbaugh points out in [3]:- How different he would find the trip today, where the main approach to the city from the northeast runs past the impressive "Democritus Nuclear Research Laboratory". Certainly Democritus made many journeys other than the one to Athens. Russell in [9] writes:- He travelled widely in southern and eastern lands in search of knowledge, he perhaps spent a considerable time in Egypt, and he certainly visited Persia. He then returned to Abdera, where he remained.

democritus of abdera (ca. 470ca. 380 BC), Greek philosopher who wasa pupil of Leucippus and extended his mentor s atomic theory.
http://scienceworld.wolfram.com/biography/Democritus.html

Extractions: Greek philosopher who was a pupil of Leucippus and extended his mentor's atomic theory. He tried to account for the observable properties of matters in terms of the shapes of their constituent atoms, which he believed to be eternal, indestructible, and unchanging. He also pursued studies in physics, astronomy, zoology, botany, and medicine. In another example of amazing insight, he maintained that the Milky Way galaxy was a conglomeration of stars. Leucippus

Conclusion Introduction Leucippus, born ca. 500 BCE, and his pupil, Democritus, born ca. 460 BCE, are credited with postulating the theory of Atoms and Void. Democritus expanded upon Leucippus' original theory and theorized on many of its detailed applications like perception. Leucippus is credited with writing only a few works, including The Great World System , in which he postulates his theory on atoms and void. Democritus was a much more prolific writer and is credited with writing fifty-two works, although some were quite short. These included his expansion on Leucippus' work in The

http://www.geocities.com/joek_bm/images/matematica/biografias/democritus.htm

Extractions: Even though he was an outstanding geometer, he is best known for his atomic theory of matter, which consisted of an elaborate and systematic perspective of the physical world. With his theory, he could explain all changes that occur in the world as changes in motion of atoms or in the way the atoms were arranged. Also, he was one of the greatest philosophers of physical science among the ancient Greeks, believing that nature behaves like a machinea highly complex mechanism. As for his mathematical contributions, little is known other than the titles of some unsurviving texts: On numbers On geometry On tangencies On mappings , and On irrationals . It is also known that he did contribute to applied mathematical problemsdealing with the volume of solids. He was also interested in physics, ethics, and law.

Democritus, Epicurus and Aristotle on atoms. Democritus. Leucippusand Democritus. Democritus is said to have discovered the atoms
http://www.mlahanas.de/Greeks/Atoms.htm

Extractions: Democritus Leucippus and Democritus. Democritus is said to have discovered the atoms, (a-tomos which is a Greek word for not divisible ), around 430 BC. He was a student of Leucippus. Democritus and Leucippus are mentioned together as having discovered the atoms but we know very little about Leucippus. Some say that Leucippus even did not exist and that this name was used by Democritus as a pseudonym. However this is very probably not true. The work The Great World System is considered to be a work of Leucippus in which the atoms and void are postulated. Although Democritus wrote many books almost nothing than a few Fragments survived and what we know are comments from Aristotle and others. How can Democritus and Leucippus discover atoms without being able to see atoms? Even at the times of Ludwig Boltzmann scientists did not believe that atoms exist. Boyle and Boltzmann and others believed this but there was no direct proof.

democritus of abdera. The Presocratic Philosophers by GS Kirk and JE Raven. IntroductionDemocritus was born at Abdera, Thrace, sometime around 458 BCE.
http://evans-experientialism.freewebspace.com/democritus.htm

Extractions: Democritus was born at Abdera, Thrace, sometime around 458 BCE. He was described as well traveled, probably visiting Babylon, Egypt, and Ethiopia, and perhaps India. He appears to have spent all of his time on scientific and philosophical studies, teaching, and writing some 60 works have been listed. Of his voluminous writings, only a few fragments of his ethical theory remain. But these fragments and the descriptions by other writers of his atomic theory put him among the foremost thinkers of his time. Aristoxenus wrote that Plato wanted to burn all the works of Democritus, but could not do so because the books were already in wide circulation. Failing this, he avoided any mention of Democritus in his own writings. Certainly, Socrates brand of argument might not have fared well against Democritus, who was described by Timon as "the guardian of discourse, a keen witted disputant". Democrituss theory of the atomic nature of the physical world, developed from that of Leucippus, is known only through the works of critics of the theory such as Aristotle and Theophrastus. It resolved the question of how a world evidently in a state of flux could nevertheless have an underlying nature that was eternal and unchanging. By positing infinitely small things that remained the same but formed different combinations with each other, Leucippus initially, and Democritus in greater detail, managed to answer the question in a way that has been subject to increasingly successful elaboration ever since. One can trace the physical theory of atoms through Epicurus, Lucretius, and Galileo to modern times.

Extractions: Athenian statesman, from the famous family of Alcmaeonids. Late in the tyranny of Hippias Cleisthenes was banished from Athens. He was said to have bribed the priestess at Delphi into guaranteeing that the oracle would advise all Spartans to overthrow the tyranny in Athens. (See Pisistratus .) Delphi, in return, got Cleisthenes' promise to help bankroll the renovation of the temple. The priestess took the bribe, the Spartans took the advice, Hippias was overthrown and Cleisthenes returned to Athens (511/10 B.C.E. to head one of two aristocratic factions. When the rival faction, headed by Isagoras, got the upperhand, the ever resourceful Cleisthenes appealed to the people and succeeded in passing a sweeping set of democratic reforms that included redefinition of the tribes of Athens (a sort of ancient gerrymandering), granting of sweeping powers to the Council of 500 ( BOULE ,) empowering of the Assembly of all citizens ( EKKLESIA ,) and instituting ostracism , the curious Athenian law by which the citizens could vote to excile for ten years, with or without cause, one of their fellow citizens.
