"Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough."
"We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on."
"If you thought you were trying to find out more about it because you're gonna get an answer to some deep philosophical question...you may be wrong!

"Science is what we have learned about how to keep from fooling ourselves."
"I believe that a scientist looking at nonscientific problems is just as dumb as the next guy."
