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

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

What is not surrounded by uncertainty cannot be the truth.

We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation.

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.

I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.
