Mayim Bialik
Mayim Bialik isn't just a neuroscientist on The Big Bang Theory, she's also one in real life! One red carpet interviewer asked her "Being on The Big Bang Theory, how many people, not that you aren’t a genius, think that you can solve calculus at the drop of a hat?" Mayim replied, "I was trained in calculus for several years. I’m a neuroscientist...you may not have known that?"
