Richard Feynman

"The test of all knowledge is experiment."

"Shut up and calculate."

"I would like not to underestimate the value of idle time."

"You are not responsible for the world, but you are responsible for your integrity."

"In the age of computers, it is very important to know how to compute."

"The Feynman Technique: Study it, teach it, fill in the gaps."

"It doesn't matter how beautiful your theory is, if it doesn't agree with experiment, it's wrong."

"I think it's much more interesting to live not knowing than to have answers that might be wrong."

"Find something that you like to do so much that you would do it for no pay."

"Fall in love with the subject you're studying, and the prizes and honors will come."

"The universe is a fix waiting to happen."

"Nature uses only the longest threads to weave her patterns."

"If you can't explain it simply, you don't understand it well enough."

"Study hard what interests you the most in the most undisciplined, irreverent, and original manner possible."

"I would hate to die and have people think all I ever did was work."

"Pleasure of finding things out is the most important aspect of a life."

"The truth is far more interesting and beautiful than any fiction."

"To develop a system of values, you must think hard about what you really care about."

"The more you know, the more you realize how much you don't know."

"All of science is built on mistakes."

"When you get to the level of detail you realize there isn't much difference between things."

"The first thing I want to emphasize is a kind of scientific attitude."

"I think nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical."

"The real problem is that the way we think about the world is wrong."

"It is impossible to truly educate a person from outside."

"In physics, you don't have to go around making trouble for yourself."

"Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric."

"The way to win is to not lose."

"Our responsibility is to do what we can, with what we have, in the time we have."

"One of the ways of stopping science would be only do experiments in the region where you know the law."
