**__Ancient Times __ ** **Leucippus is a Greek philosopher who originated the theory of atomism. It says that matter is homogeneous but that it consists of many small indivisible particles. These atoms are always in motion and form diverse compounds through their collisions and regroupings. A cosmos is produced by the collision of atoms that gather together into a “whirl” and the drum-shaped Earth is sited in the centre of man’s cosmos. Leucippus was the first philosopher who proved the existence of space. His atomic theory of indivisibles was further developed by Democritus later on. **

Democritus __**

- Date of Death: 370 B.C. - Country of Origin: Abdera, Greece Democritus lived a full life to be at least 90. Throughout his life, he had a main goal, which was to live his life cheerfully. This meant having peace of mind and being undisturbed; yet this did not happen, all his life he was a very active man who was always involved in the politics and the government of Greece. He was a very revolutionary man, he was the first person to deny that every human has a soul that lives after the body has died. In his life he had many different interests and he often wrote books about them. His books were not always preserved though because the topic and arguements did not always please Plato. Plato was the person who chose which books were good enough to be preserved. Out of all of the books that Democritus wrote, the one that made him most famous was his atomic theory which he presented in 404 BC when he was round 50 years old. The atomic theory that Democritus developed stated that there is an infinite number of atoms and they are so small that they cannot be seen. These atoms got together and formed objects that were big enough to see and feel, yet when the atoms separated the object was destroyed. This was the base of his atomic theory which he derived from Leuccipus' atomic theory. Democritus did some changes to this atomic theory and added same observations from his own discoveries. Some of the facts that Democritus contributed to the atomic theory included that the atom was the smallest particle of matter and that it could not be broken down. "The physical universe had 2 basic ingredients: impenetrable atoms and penetrable space." Space was infinte and the atoms were infinte in number. He also said in his theory that the atoms were moved by an inner force that never stopped and not by an outside force. He thought that the atoms could not be destoryed nor could they multiply. This thought was the base for the theory presented many years later called the law of conservation of matter. An intersting view that Democritus presented in his atomic theory was that time did not exist. He thought that the whole universe was "temporarily everlasting and spatially boundless".

- Date of Birth: lived during the 600 BC - Date of Death: lived during the 600 BC - Country of Origin: India Kanda founded a school named Vaisesikautra in which science, philosophy and religion were taught. The center of all Kanada's studies was his atomic theory. It was said that his atomic theory was more advances than the Greek's philosophies. Kanada's atomic theory stated that matter was made of a limited amount of paramanus (atoms) which could not be divided, created or destroyed. Each atom is different from the other and whey they join they form the 4 elements: earth, water, air, and fire. He believed that the force for the atom's to join was caused by the will of Isvara (Hindu God). **
