Proof is the idol before whom the pure mathematician tortures himself.
Arthur Eddington
Reductio ad absurdum, which Euclid loved so much, is one of a mathematicians finest weapons. It is a far finer gambit than any chess play: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game.
Godfrey H. Hardy
Beware of testing too many hypotheses; the more you torture the data, the more likely they are to confess, but confession obtained under duress may not be admissible in the court of scientific opinion.
Stephen Stigler
What if this world was free, would there be world peace?
The Spudmonsters
Wake up. I’ve been watching you. Come closer. Closer. 28 days. 6 hours. 42 minutes. 12 seconds. That is when the world will end.
