10 Celebrities Who Light Up the World With Their Intelligence

6. Mayim Bialik is a brilliant mind on and off camera.

The actress plays Amy Farrah Fowler in the comedy show The Big Bang Theory, a scientist who specializes in Neurology, so this is one of those times in which art imitates real life. Despite having been in front of the camera since she was a child (in the show Blossom), Bialik graduated from UCLA with a Ph.D. in Neuroscience and also did some research in Jewish and Hebrew studies.
