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.

I have a friend who's an artist, and he sometimes takes a view which I don't agree with. He'll hold up a flower and say, "Look how beautiful it is," and I'll agree. But then he'll say, "I, as an artist, can see how beautiful a flower is. But you, as a scientist, take it all apart and it becomes dull." I think he's kind of nutty. [...] There are all kinds of interesting questions that come from a knowledge of science, which only adds to the excitement and mystery and awe of a flower. It only adds. I don't understand how it subtracts.

A very great deal more truth can become known than can be proven.

Outside of their particular area of expertise scientists are just as dumb as the next person.

If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.

If you don't like it, go somewhere else, to another universe where the rules are simpler.

The present situation in physics is as if we know chess, but we don't know one or two rules.
