Personal Quote:

We have Nobel Prize winners asking if they can guest-star on the show. The image of the scientist in the last 10 to 15 years has changed dramatically. It used to be the pasty guy in the basement with beakers, and now it's Steve Jobs. They're almost the rock stars of our age. See more »

Trivia:

His father was of Polish descent. His mother is of Irish and Italian ancestry. See more »
