Democritus was a Greek philosopher, who developed the atomic theory of the universe, which he critiqued after being originally purposed by his teacher Leucippus. He was born into a family where his father was a wealthy nobleman. He believed atoms were always moving, and had characteristics such as position, shape, size and that they move through space. He traveled around the world according to that time period and gave speeches about his findings and would share his views with people who would listen.
