I don't believe anybody can really grasp everything that's even in one textbook.

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.

As soon as you go into any biological process in any real detail, you discover it's open-ended in terms of what needs to be found out about it.

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.
