F A Wilczek in this interview

He is good-natured, funny and thought to be among the smartest men in physics: Frank A. Wilczek, 58, a professor at the Massachusetts Institute of Technology who was one of three winners of the 2004 Nobel Prize in Physics.

Here is an edited version of two conversations with Dr. Wilczek, in October and this month.
