It’s been long since I have visited Cambridge before, probably it was already 4 years ago. I lived in Cambridge for half a year, as a visiting researcher then at DAMTP (Department of Applied Math and Theoretical Physics), universtiy of Cambridge. I have good memories on my days at Cambridge.
Last time when I was here at Cambridge, I couldn’t imagine that I would be working on nuclear physics. The talk I gave here 4 years ago was on ADHM construction of instantons and its D-brane realization, and the motivation was purely mathematical physics. But this time, again in my talk I told about ADHM construction, but now applied to nucleon nucleon interaction realized and computed in string theory. It is interesting that, although the mathematical tools are quite similar to each other (and almost the same), the motivations were totally different.
Discussions with my friends at DAMTP were joyful, and are always insightful. And, one more thing — winter in Cambridge, it is beautiful.
