“Nature has a great simplicity and therefore a great beauty”

“Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.”

“I was terrible in English. I couldn't stand the subject. It seemed to me ridiculous to worry about whether you spelled something wrong or not, because English spelling is just a human convention--it has nothing to do with anything real, anything from nature. Any word can be spelled just as well a different way.”

“Why nature is mathematical is, again, a mystery.”

“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..”

“It doesn't make a difference how beautiful your guess is. It doesn't make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it's wrong.”

“It is surprising that people do not believe that there is imagination in science. It is a very interesting kind of imagination, unlike that of the artist. The great difficulty is in trying to imagine something that you have never seen, that is consistent in every detail with what has already been seen, and that is different from what has been thought of; furthermore, it must be definite and not a vague proposition. That is indeed difficult.”
