Only professional mathematicians learn anything from proofs. Other people learn from explanations.

— Ralph P. Boas, Jr

A mathematical proof is beautiful, but when you're finished, it's really only about one thing. A story can be about many things.

— Bonnie Jo Campbell

Any good theorem should have several proofs, the more the better.
