Richard Feynman

"I have no responsibility to live up to what others expect of me. That's their mistake, not my failing."

"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."

"We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress."

"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."

"Physics isn't the most important thing. Love is."

"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."

"The first principle is that you must not fool yourself and you are the easiest person to fool."

"You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts."

"If you thought that science was certain - well, that is just an error on your part."

"Science is what we have learned about how to keep from fooling ourselves."

"Physics is like sex: sure, it may give some practical results, but that's not why we do it."

"Science is what we have learned about how to keep from fooling ourselves."

"Physics isn't the most important thing. Love is."

"Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it."

"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."

"Philosophy of science is about as useful to scientists as ornithology is to birds."

"Religion is a culture of faith; science is a culture of doubt."

"I believe that a scientist looking at nonscientific problems is just as dumb as the next guy."

"You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts."

"For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."
