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

The single biggest threat to man's continued dominance on the planet is the virus.

I have many shortcomings. I feel very lucky to have been able to have what I've had.

To have the recognition of your colleagues is great. The public attention is a mixed blessing.

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.

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'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.
