jan 1, 442 BC - Democritus' Atomic Theory

Description:

Democritus' theory was discovered in 442 BC. Through observations, he concluded that if you keep dividing matter in half, you will finally result with an "atomos." Atomos means that the particle can't be broken down any farther. Below is a picture of an atom being divided into smaller atoms.
