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: Version for printing 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.

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.

Extractions: Atom Democritus of Abdera , philosopher (~460 B.C. - ~360 B.C.), he argued that it is impossible for matter to be divisible ad infinitum , and that matter at the fundamental level consists of indivisible, impenetrable and homogeneous pieces he called atoms atomon meaning indivisible). He was thus able to explain the changes in the world that surrounded him as due to variations in the motion of atoms and in their arrangement. According to Democritus, the whole Universe is composed of atoms of different 'sizes, weights, and shapes' and Void, which is empty space between atoms.

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

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 (and maybe Philolaus ). Democritus and Leucippus are mentioned together as having discovered the atoms but we know very little about Leucippus. Some (Epicurus) saids that Leucippus 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
