The field of quantum valence fluctuations was another older interest which became much more active during this period, partly as a consequence of my own efforts.

I have also testified repeatedly and published some articles in favor of Small Science.

The first months at Harvard were more than challenging, as I came to the realization that the humanities could be genuinely interesting, and, in fact, given the weaknesses of my background, very difficult.

The Nobel Prize gives one the opportunity to take public stands.

A souvenir of those years is a small cottage on the cliffs of Cornwall, where Joyce and I spend a spring month every year, hiking and seeing friends.

My belief is based on the fact that string theory is the first science in hundreds of years to be pursued in pre-Baconian fashion, without any adequate experimental guidance.

The prize seemed to change my professional life very little.
