“I realized a long time ago not to worry about whodunnit; the more answers you find, the more questions they'll keep raising.”

“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! It may be that you can't get an answer to that particular question by finding out more about the character of nature. But my interest in science is to simply find out about the world.”

“It’s true what they say about answers only leading to more questions. There will always be more to find out, more to learn, more to do.”

“In answer to a question you asked me not a long ago, a question I didn’t answer at the time…it is worth it. Love is a perilous dance too, you see. And if we stop dancing, we’ll die.Don’t ever stop dancing.”

“Worry about the things you can control; the rest will either work themselves out, or they'll kill you. Either way, no more worries.”

“There are works which wait, and which one does not understand for a long time; the reason is that they bring answers to questions which have not yet been raised; for the question often arrives a terribly long time after the answer.”
