Although I am a public figure, I'm still a little shy. I don't think my own personality is important. I prefer to keep some small dosage of privacy.

I'd like to put in a vote for the intrinsic fascination of science.

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.

I did get a very fine education, and not just in science. It took some pressure on the part of my elders to convince me that I really should take an interest in humanities.
