I think we have to believe we are here for some purpose, and I know there are many cynics who will deny it, but they don't live as if they deny it.

When I was in high school, I became interested in cytochemistry: chemical analysis under the microscope, and trying to understand the composition of cells.

I wish I had a talent for dropping things as well as taking on new ones. It gets to be quite a clutter after a while.

A Swedish newspaper reporter called and said, You've been awarded the Prize. I was quite sure it was a practical joke.

I believe I am a person with unusual talents. I think I'd be a liar or stupid if I were to deny that.

I'm not easily inhibited by the fact that I don't know something about a subject. It doesn't stop me from dabbling in it.

Everybody has to learn for the first time.
