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.

I acquired an admiration for Japanese culture, art, and architecture, and learned of the existence of the game of GO, which I still play.

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

Feynman's cryptic remark, "no one is that much smarter ...," to me, implies something Feynman kept emphasizing: that the key to his achievements was not anything "magical" but the right attitude, the focus on nature's reality, the focus on asking the right questions, the willingness to try (and to discard) unconventional answers, the sensitive ear for phoniness, self-deception, bombast, and conventional but unproven assumptions.

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 ability to reduce everything to simple fundamental laws does not imply the ability to start from those laws and reconstruct the universe.

The prize seemed to change my professional life very little.
