How Does the Man of Steel Shave? Let's Ask Mayim Bialik


Mayim Bialik plays a neuroscientist on TV, which isn't a stretch. She earned a PhD in neuroscience in real life. (Her thesis: "Hypothalamic Regulation in Relation to Maladaptive, Obsessive-Compulsive, Affiliative, and Satiety Behaviors in Prader-Willi Syndrome." So, yeah.)

Mayim puts all that knowledge to good use pondering one of the comic world's most enduring questions: "How does the Man of Steel shave?" Gillette has gathered some opinions on the matter including Mayim's, that bring in some pretty complex concepts about enzymes and proteins (don't worry - there are some handy motion graphics to bring it all to life). Check out for more explanations from geeky celebs.
