29 янв 400 г. до нашей эры - Democritus and Leucippus

Описание:

The Greek philosophers Democritus and Leucippus proposed the first model of the atom:
1. Matter is composed of atoms separated by empty space through which the atoms move.

2. Atoms are solid, homogeneous, indivisible, and unchangeable.

3. All apparent changes in matter result from changes in the groupings of atoms.

4. There are different kinds of atoms that differ in size and shape.

5. The properties of matter reflect the properties of the atoms the matter contains.

It gained little traction, with more non-believers than believers
