On Finding Out About Atoms

Astrophysicist Paul Sutter from Ohio State University gives us here a little bit of a history of how we were able to figure out atoms exist.

From Dalton's multiple proportions to JJ Thomson's cathode ray experiment, with various contributions from Ernest Rutherford and Albert Einstein among others, this gives us a bit of insight into the discovery of the atom.
