Richard Feynman Quotes

You keep on learning and learning, and pretty soon you learn something no one has learned before.

Things on a very small scale behave like nothing that you have any direct experience about.

There are thousands of years in the past, and there is an unknown amount of time in the future. There are all kinds of opportunities, and there are all kinds of dangers.

I have to keep going to find out ultimately what is the matter with it in the end.

i have a friend who’s an artist and he’s sometimes taken a view which i don’t agree with very well. he’ll hold up a flower and say, “look how beautiful it is,” and i’ll agree, i think. and he says - “you see, i as an artist can see how beautiful this is, but you as a scientist, oh, take this all apart and it becomes a dull thing.” and i think that he’s kind of nutty. first of all, the beauty that he sees is available to other people and to me, too, i believe, although i might not be quite as refined aesthetically as he is; but i can appreciate the beauty of a flower. at the same time i see much more about the flower than he sees. i can imagine the cells in there, the complicated actions inside which also have a beauty. i mean it’s not just beauty at this dimension of one centimeter, there is also beauty at a smaller dimension, the inner structure. also the processes, the fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting - it means that insects can see the color. it adds a question: does this aesthetic sense also exist in the lower forms? why is it aesthetic? all kinds of interesting questions which shows that a science knowledge only adds to the excitement and mystery and the awe of a flower. it only adds; i don’t understand how it subtracts..

I believe that we must attack these things in which we do not believe. Not attack by the method of cutting off the heads of the people, but attack in the sense of discuss. I believe that we should demand that people try in their own minds to obtain for themselves a more consistent picture of their own world; that they not permit themselves the luxury of having their brain cut in four pieces or two pieces even, and on one side they believe this and on the other side they believe that, but never try to compare the two points of view. Because we have learned that, by trying to put the points of view that we have in our head together and comparing one to the other, we make some progress in understanding and in appreciating where we are and what we are. And I believe that science has remained irrelevant because we wait until somebody asks us questions or until we are invited to give a speech on Einstein’s theory to people who don’t understand Newtonian mechanics, but we never are invited to give an attack on faith healing, or on astrology — on what is the scientific view of astrology today.

the whole problem of discovering what was the matter, and figuring out what you have to do to fix it–that was interesting to me, like a puzzle

I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously… The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big.

Western civilization, it seems to me, stands by two great heritages. One is the scientific spirit of adventure — the adventure into the unknown, an unknown that must be recognized as unknown in order to be explored, the demand that the unanswerable mysteries of the universe remain unanswered, the attitude that all is uncertain. To summarize it: humility of the intellect.

"Once in Hawaii I was taken to see a Buddhist temple. In the temple a man said, "I am going to tell you something that you will never forget." And then he said, "To every man is given the key to the gates of heaven. The same key opens the gates of hell.

I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, ‘But how can it be like that?’ because you will get ‘down the drain’, into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.

If a law does not work even in one place where it ought to, it is just wrong.

For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

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.

"A philosopher once said, "It is necessary for the very existence of science that the same conditions always produce the same results." Well, they don't!"
