The experiment that provided strong evidence for the existence of atoms is the Brownian Motion experiment. Conducted by Albert Einstein in 1905, he explained the erratic motion of tiny pollen grains in water as the result of collisions with water molecules. This molecular theory of heat supported the atomic theory, providing tangible proof that atoms and molecules existed even though they were too small to be seen directly.
