Secrets of the cosmos will begin to unravel. I, for one, can't wait.

I considered going into business or becoming a lawyer - not for the money, but for the thrill of problem-solving.

There is real confusion about what it means to be right and wrong - the difference between what spiritual beliefs are and what science is.

When I was in school I liked math because all the problems had answers. Everything else seemed very subjective.

Scientists actively approach the door to knowledge—the boundary of the domain of what we know. We question and explore and we change our views when facts and logic force us to do so. We are confident only in what we can verify through experiments or in what we can deduce from experimentally confirmed hypotheses.

Faith just doesn't have anything to do with what I'm doing as a scientist. It's nice if you can believe in God, because then you see more of a purpose in things. Even if you don't, though, it doesn't mean that there's no purpose. It doesn't mean that there's no goodness. I think that there's a virtue in being good in and of itself. I think that one can work with the world we have.

Science is a combination of theory and experiment and the two together are how you make progress.
