Leucippus

-Leucippus's discovery of the atom came about as a response to Zeno of Elea who theorized that nothing that truely is (such as mountains) can change or move. Leucippus did not believe this was true, instead he speculated that all things in existence have to have motion and that everything is made up of an infinite amount of atoms and that the "dissolution of these particles leads to the destruction or death of that object".

__**Leucippus' Bio**__ Leucippus was born around 480 BC in possibly Miletus, Asia Minor and died around 420 BC. Although very little is known of Leuciuppus' life and his very existance was called into question by Epicurus, one of Democritus' pupils, Leucippus is suspected to have founded a school on the coast of Thrace at the mouth of the Nestos River now a present day town in Greece named Avdhira. The school was called the School at Abdera, Abdera was a prosperous political member of the Delian league.

-Democritus reasoned that all matter was made of small particles, which he called atoms, floating in a void or vacuum. This was later discovered to be true.

__**Democritus' Bio**__ Democrituswas an Ancient Greek philosopher born in Abdera, Thrace, Greece. He formulated an atomic theory for the cosmos. His exact contributions are difficult to disentangle from his mentor Leucippus, as they are often mentioned together in texts. Their hypothesis on atoms is remarkably similar to modern science's understanding of atomic structure, and avoided many of the errors of their contemporaries. Largely ignored in Athens, Democritus was nevertheless well-known to his fellow northern-born philosopher Aristotle. Plato is said to have disliked him and to have envied him. Many consider Democritus to be the "father of modern science".

__**Aristotle's Bio**____ He was born and raised in Stagira in the north of Greece in 367 BC. At the age of 17 he studied at Plato's Academy. He then stood there for 20 years in which he not only studied but also was a teacher. In 335 BC he returned to Athens where he founded his school the Lyceum. Aristotle moved to Chalcis after the death of Alexander the Great because he felt it was too dangerous. He died at the age of 62.
