Democritus (/ d ɪ ˈ m ɒ k r ɪ t ə s /, dim-OCK-rit-əs; Greek: Δημόκριτος, Dēmókritos, meaning "chosen of the people"; c. 460 – c. 370 BC) was an Ancient Greek pre-Socratic philosopher from Abdera, primarily remembered today for his formulation of an atomic theory of the universe. [2] Democritus wrote extensively on a wide ...
The work of Democritus survives only in secondhand reports, some of which are unreliable or conflicting. Much of the best evidence of Democritus' theory of atomism is reported by Aristotle (384–322 BCE) in his discussions of Democritus' and Plato's contrasting views on the types of indivisibles composing the natural world.

Aristotle's 4th-century BCE record of Leucippus and Democritus's philosophy is the oldest surviving source on the subject, [65] though he did not distinguish who developed which atomist ideas. [28] [29] Aetius also wrote about Leucippus, but it was well after Leucippus's own time and derivative of previous writings on the subject. [66]
Epicurus studied in Athens with Nausiphanes, who was a follower of Democritus and a student of Pyrrho of Elis. [73] He accepted Democritus' theory of atomism, with improvements made in response to criticisms by Aristotle and others. [74] His ethics were based on "the pursuit of pleasure and the avoidance of pain". [75]
His experiments suggested not only that cathode rays were over 1,000 times lighter than the hydrogen atom, but also that their mass was the same in whichever type of atom they came from. He concluded that the rays were composed of very light, negatively charged particles which were a universal building block of atoms.
The thesis is a comparative study on atomism of Democritus and Epicurus on contingency and dedicated to Marx's friend, mentor, and future father-in-law, Ludwig von Westphalen. Francis Wheen describes it as "a daring and original piece of work in which Marx set out to show that theology must yield to the superior wisdom of philosophy". [ 1 ]
No, the “Great Experiment” did not happen in real life. Although based on actual monarchs, Queen Charlotte reimagines the events of Georgian-era London.
Epicurus applies his method of inference (the use of observations as signs, Asmis' summary, p. 333: the method of using the phenomena as signs (σημεῖα) of what is unobserved) [24]: pp.175–196 immediately to the atomic theory of Democritus. In Aristotle's Prior Analytics, Aristotle himself employs the use of signs.
