Aristotle was born in 384 BC and lived until 322 BC. He was a Greek philosopher and scientist, who shares with Plato being considered the most famous of ancient philosophers. He was born at Stagira, in Macedonia, the son of a physician to the royal court. When he was 17, he went to Athens to study at Plato"s Academy. He stayed for about 20 years, as a student and then as a teacher. When Plato died in 347 BC, Aristotle moved to Assos, a city in Asia Minor, where a friend of his named Hermias was the ruler. He counseled...
circular motion". The heavens, according to, must be made of a fifth, and different element, which he called "aither." The strongest element, aither can"t change other than change of place in a circle movement. Aristotle"s theory that linear motion always takes place through a resisting medium is actually true for all planets that we can see motions.

Honestly, to me it seems like Aristotle was crazy. Many of his theories were completely false, and I don"t really understand why he is so famous. If I started saying the things he says now, I"d be thrown into a mental hospital.
