â Surprisingly, some of these Greek ideas led to similar modern ideas. Democritus (462-370 B.C.): proposed that all matter was made up of tiny, indivisible. particles called atomos (meaning âindivisibleâ) or atoms. Empedocles (490-430 B.C.): suggested all matter was composed of four basic elements: air, water, fire, and earth.
Contribution. Democritus used reasoning instead of science when he came up with his theory. He based his work off of the philosophers Leucippus and Anaxagoras. Democritus was the first person to suggest that materials were made up of smaller things. He called these things 'atomos'. He theorized that every material had its own 'type' of atomos and that no matter how small you cut something up, it would always have the same properties.
