But this is still an s-wave interaction, for bosons. Who first thought of the atom?. Democritus. Leucippus. Democritus and Leucippus. ~440 BC. They were the first philosophers that believed that atoms existed.. They thought that you could cut something in half , over and over, until you eventually get to a particle so small that it can no longer be cut In half.. Wave-Particle Duality.
