WebThe atomic philosophy of the early Greeks Leucippus of Miletus (5th century bce) is thought to have originated the atomic philosophy. His famous disciple, Democritus of Abdera, named the building blocks of matter atomos, meaning literally “indivisible,” about 430 bce. WebHe thought that all matter was made of tiny particles called atoms, which he imagined as tiny spheres that could not be divided. Nearly 100 years later, J J Thomson carried out experiments and...
