Mathematics poll

[ciphergoth]

Inspired by a similar poll in palmer1984's journal.

About the "proof" question below: examples of the kind of proof I mean would be a proof that there are infinitely many primes, or that the square root of two is irrational, or of Pythagoras's Theorem. A proof in computer science counts too. By "know a proof off by heart" I mean that you'd be able to convince someone of it at a party, if they had the background to follow the proof.

If you know lots of proofs, feel free to choose one you particularly like in the last question...

I suggest that the proof I've nominated is the only one worth taking to parties if you want to talk maths to non-mathmos, thus getting your maths fix in but also avoiding getting stuck in the corner all night discussing group theory or diagonal proofs. :o)
