Democritus
built 633 days ago
Democritus was born at Abdera, about 460 BCE, although according to some 490. His father was from a noble family and of great wealth, and contributed largely towards the entertainment of the army of Xerxes on his return to Asia. As a reward for this service the Persian monarch gave and other Abderites presents and left among them several Magi. Democritus, according to Diogenes Laertius, was instructed by these Magi in astronomy and theology. After the death of his father he travel in search of wisdom, and devoted is inheritance to this purpose, amounting to one hundred talents. He is said to have visited Egypt, Ethiopia, Persia, and India.

For Democritus, the Void was a vacuum, an infinite space containing the infinite number of atoms making up the physical world. These atoms, according to Democritus, are eternal, indivisible, incompressible, and composed of homogeneous matter that entirely fills the space they occupy.

Diogenes Laertius lists a large number of works by Democritus on many fields, including ethics, physics, mathematics, music and cosmology. Two works, the Great World System and the Little World System, are sometimes ascribed to Democritus, although Theophrastus reports that the former is by Leucippus (DK 68A33). There is more uncertainty concerning the authenticity of the reports of Democritus' ethical sayings. Two collections of sayings are recorded in the fifth-century anthology of Stobaeus, one ascribed to Democritus and another ascribed to an otherwise unknown philosopher ‘Democrates’. DK accepts both as relating to Democritus, but the authenticity of sayings in both collections is a matter of scholarly discussion, as is the relationship between Democritus' atomism and his ethics.

It is a great pity that Democritus was not more explicit about the role of virtue, especially in the light of the interesting fragments about shame. ‘Feel no more shame before other people than before yourself. Don’t do a wrong thing any more if nobody will know than if every single person will know. Most of all feel shame before yourself, and set this up as a law for your soul, so as to do nothing inappropriate’ (

Democritus was the name for a Remote Scanning Outpost in the Solar System. Democritus was in orbrit around Pluto, the ninth planetary body in the system. This station was undetected by the Covenant as long as November, 3, 2552, during The Second Battle of Earth. It was ... still functional. It monitored Slipspace activity and picked up a message sent from Cortana using Forerunner technology and another signal piggybacked on it by Dr. Catherine Halsey.[1]

Democritus is a spin-off of Celeste (http://code.google.com/p/celeste). Celeste is 3D and electromagnetic and fully implicit. Democritus is 2D electrostatic (but allows for a prescribed B field) and it is both implicit or explicit. Its strength is the ability to handle complex geometries within Cartesian or Cylindrical metrics. Furthermore it employs the immersed boundary method to handle complex plasma/wall interaction. The code has several utilities to treat dusty plasmas.
