What made you decide to visit Brown for the Year of China? Professor (of Physics) Chung-I Tan wrote to me and mentioned this event. Basically, he was interested in talking about the whole issue of China and India and the relations between India and China, and that’s what I’ve been working on for a very long time now. So it seemed to me it was a very good fit, and I’ve always enjoyed coming to Brown. It seemed like an interesting thing to do.
