Theoretical physicist Frank Wilczek is Herman Feshbach Professor of Physics at Massachusetts Institute of Technology and Origins Project Distinguished Professor at Arizona State University. He received the Nobel Prize in 2004 for his work on asymptotic freedom in the theory of strong interaction. From the Origins Web Site.
The lecture was actually rather enjoyable. I was afraid it would be over my head but Professor Wilczek has a way of putting things that are not only comprehensible but funny in a geeky sort of way.
He posed the plausibility of parallel 2 dimensional worlds that left one thinking.
The dialogue following the lecture was the typical physicist banter and subtle competition fueled a little disagreement here and there. It was a good evening.
And I got my 10th and final book signed. Professor Krauss was gracious as always.
