How long did it take since the first theories about the atom were documented until it was actually proven?
In the 5th cent. B.C. the Greek philosophers Democritus and Leucippus proposed that matter was made up of tiny, indivisible particles they called atom, or in Greek "a-tomos".
By the 19th century, technology had advanced greatly and many elements had been discovered to work with. Using the available elements scientist such as John Dalton and Amedeo Avogadro forced them to interact with one another. From these interactions they were able to prove the existence of the atom.
Too bad we'll all be dead. Hope someone tells your ghost when it happens.
