Famous Quotes & Sayings

Richard P. Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.

Richard P. Feynman

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

Richard P. Feynman

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

Richard P. Feynman

Scientists are explorers. Philosophers are tourists.

Richard P. Feynman

The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. ... If you will simply admit that maybe [Nature] does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that.

Richard P. Feynman

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

Richard Dawkins

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Richard Whately

To teach one who has no curiosity to learn, is to sow a field without ploughing it.

Robin Williams

If I could light my own farts I could fly to the moon or at least Uranus.

Wayne Smith

Cuba seems to have the same effect on US administrations as the full moon has on werewolves.

Wallace Stevens

After a lustre of the moon, we say We have not the need of any paradise, We have not the need of any seducing hymn.

Sally Ride

The view of earth is spectacular from space. Most people imagine that when astronauts look out the window of the shuttle they see the whole earth like that big blue marble that was made famous by the flights that went to the moon. But the shuttle is much, much closer than those astronauts were. So we don't see the whole planet, the whole ball at once, we just see parts of it.

Rudy Rucker

For me, the best thing about Cyberpunk is that it taught me how to enjoy shopping malls, which used to terrify me. Now I just imagine the whole thing is two miles below the moon’s surface, and that half the people’s right-brains have been eaten by roboticized steel rats. And suddenly it’s interesting again.

Van Jones

Rather than continuing to base our economy on a finite supply of dead things, we can base it on sources that are practically infinite and eternal: the sun, the moon, and the Earth's inner fire.

Roberto Bolano

The moon is fat and the night air is so pure it seems edible.

Sarah Dessen

We sat there, not talking, for a few minutes. He ate the Moon Pie; only skinny people can scarf down junk food like that. Finally, I said, "Norman?" "Yeah?" "Are you ever going to show me the painting?" "Man," he said. "You are, like, so impatient." "I am not," I said. "I've been waiting forever." "Okay, okay." He stood up and went over to the corner, picking up the painting and bringing it over to rest against the bright pink belly of one of the mannequins. Then, he handed me a bandana. "Tie that on.

Whoopi Goldberg

I don't think in terms of failure....I don't feel like anyone outside of me should be setting limitations. People should be encouraged to shoot for the moon.
