Mayim Bialik often appeared on screen when she was a child. Her role in the Blossom series turned out to be a huge success for her. Afterward, she mostly stayed behind the scenes, giving her voice to cartoon characters. Her real breakthrough was awaiting her in 2010 when she became a part of the crew of The Big Bang Theory. However, Bialik is quite successful beyond the cinema world as well — she has her Ph.D. in Neuroscience.
