 * __ Leuippus __


 * There is nothing known about Leuippus's life. When and where his birth was is even in the air. Leuippus was the teacher of Democritus and this is why people know him. Leuippus basically came up with the word atom and idea. He knew that atoms made up everything and he also thought that they were always in motion. Leuippus also said that an atom is unchanging and stays the same throughout time.**

(520 B.C. - 450 B.C.) He is from a Greek city in southern Italy and he is another Greek philosopher. Like the other philosophers of this time he founded a school and he was a teacher there. He dealt a lot with "The Way of Truth" and "The Way of Opinion" and this had to do with the way the world looked, felt, and appeared to everybody living on it. This study was very deep and in the study he started to look at the atom. He said the atom was that he denied that there was any movement with the atoms. The moving of the atoms was an illusion and Democritus believed everything he said except when he talked about the illusion.**
 * __Parmenides__

(460 B.C. - 370 B.C.) ​ Democritus is a Greek Philosopher from northern Greece and he was the first to propose a atomic theory. Little is known about his life because of how long ago he lived. But he was part of a noble, wealthy family. He gained most of his knowledge from traveling, he traveled to Asia and all over Greece trying to gain more knowledge. The person who started to teach Democritus about atoms was Leuippus. But Democritus went into much more detail with his atomic theory. In Democritus's atomic hypothesis he really tried to define the atom. He came up that atoms are in everything and make up everything. He said there is in infinite amount adn vary in size and in shape. In Democritus's theory the atoms have no charge and are just floating around in all objects. He also did not do any experiments while coming up with this theory.**

taught the great likes of Alexander the Great. That is impressive because of the significance of Alexander the Great in Europe. He was also head of a school and taught future kings. Aristotle had about the same views as Democritus that the atom was indivisible. The reason that Aristotle got more notice was because he had a higher rank in society people liked him more so they listened to what he said as opposed to Democritus. Aristotle said that there was only four pieces of matter in the world and they were air, fire, water, and earth. The atoms were made up of these four elements.**
