If I'm flying to China, I can sit and think about a problem. Other scientists have to go to the lab. I'm always thinking about maths, even when I'm doing other things. A lot of the time you're going up blind alleys and it's very frustrating, but then you have a sudden rush of ideas. You can live off that for quite some time.

What cracks me up is people who think I don't take baseball seriously. It's the most important thing in my life. They don't know how hard it is for me to get a bad game out of my mind. I still can't, but I'm getting better.
