Richard P. Feynman Mathematics Quotations

This is not very important what I'm doing. I'm just proving something.

We decided that 'trivial' means 'proved'. So we joked with the mathematicians: We have a new theorem- that mathematicians can prove only trivial theorems, because every theorem that's proved is trivial.

Some things that satisfy the rules of algebra can be interesting to mathematicians even though they don't always represent a real situation.

Everybody who reasons carefully about anything is making a contribution ... and if you abstract it away and send it to the Department of Mathematics they put it in books.

Mathematics is not just a language. Mathematics is a language plus reasoning.

The correct statement of the laws of physics involves some very unfamiliar ideas which require advanced mathematics for their description. Therefore, one needs a considerable amount of preparatory training even to learn what the words mean.
