1. History of the atom- Democritus

Democritus lived in c.460-c.370 B.C. He was a Greek philosopher of Abdera. He was the pupil Leucippus. He held that all things were composed of particles, known as atoms.He said that they were underived, indivisible, and and indestructable.Democritus postulated the constant motion of atoms and, on this basis, explained the creation of worlds. He held that the whirling motion caused by the falling of atoms resulted in aggregations( a group or mass of distinct or varied things, persons) —the heavier atoms forming the earth and the lighter ones theheavenly bodies. He taught that what the senses perceive as quality is merely the result of a specific quantitative distribution of atoms. Ancient Greek philosophers did not do experiments but in other ways their approach was a bit like modern science.
