Explorations into chemistry were done in our basement, sometimes with friends, and my parents must have had quite a bit of confidence in my abilities when they allowed me to experiment with explosive mixtures.

I think both running and science reflect certain character traits. I have endurance, patience, and ambition. I'm willing to work hard toward a goal, to push myself and overcome limits. Running and science both let me express these traits.

When I run, I think about everything: physics, family problems, plans for the weekend. I haven't made any big discoveries on a run, but it does give me time to think through problems. Some solutions are obvious, but they are only obvious when you are relaxed enough to find them.

Bose and Einstein had triggered low-temperature experiments that have led to the discovery of new matter. I owe my work and my Nobel to them.
