Thomson vs. Democritus

Thomson used the scientific method because he EXPERIMENTED with the atom, unlike Democritus. Democritus just sat there looking like a troll and thinking about atoms. For it to be the legit scientific method, you have to experiment and do other stuff.

J. J. Thomson

Was a cool, sciency-type guy in the late 1800's.  Do you know this muffin-model man?
