# The matter of proofs

Is this list a joke? Is this what mathematicians call humor: a casual mockery of religion, philosophy and medicine? Is this their idea of

funny?One despairs thinking this may be the case.

Or is this

how things really work?

An important new addition to the stuffy ol' methods of proof and number --- faith-based mathematics, as inspired by the heroic efforts of theologians and friends of complementary and alternative methods (CAMs) all over the ages!

So, suppose you wanted to prove that pi, that tricky mathematical constant, was equal to three; or suppose you wanted to prove all functions are continuous. (You know, have no jumps in them. Not that this is going to help you much if it needed to be told.)

- Proof by faith: We have no proof. That is the proof. If you question our proof, you're an insensitive prick.
- Proof by a test of faith: There's a counterexample. We will hope it goes away.
- Proof by a miracle: A three-line proof; the second line is "Then a miracle happens."
- Proof by prayer: Whine upwards until the problem goes away. (Works for grad students. Professors, eh, not so much.)
- Proof by devil: "What? You have a counterexample? The devil must have tricked you. Out, devil! Out!"
- Proof by a sign from God: "I saw three gaunt letters of smoke in my dream, yea, and the letters were 'Q' and 'E' and 'D'... And this is what they mean: It is
*proven!*" - Proof by a vision: "Can you see it? The proof! It's coming in through the walls!"
- Proof by peer pressure: "Of course you know all functions are continuous. You wouldn't want to be
*sad and alone*, right?" - Proof by odium: "Hitler didn't believe all functions are continuous. What, you want to agree with Hitler?"
- Proof by the life of Jesus: "Jesus was a nice guy. Everyone likes Jesus. I think this verse means Jesus said all functions are continuous."
- Proof by witnessing: "I have seen the proof!" "Me too, brother!" "Praise the proof!"
- Proof by separate magisteria: The proof exists in a
*different world*. Since you can't go and see it, you must believe me when I say it is as I say. - Proof by morality: "Discontinuous functions would be evil, ugly, troublesome and unspeakably horrid. If there was a discontinuous function, I'd probably go insane and rape your granny or something. Is that what you want me to do? Huh?"
- Proof by an appeal to optimism: "It would be terrible if this function wasn't continuous. Therefore it is."
- Proof by Hell: "If you don't believe all functions are continuous, you could become a grad student of Professor Mumblescream. Do you want that?"
- Proof by teleology: "Things would get pretty damn unspeakably complicated if all functions weren't continuous. Since considering such a bummer would be grant-destroyingly hopeless, all functions are continuous."
- Proof by ontology: "Mathematics is idealism. Can you conceive of anything more ideal than all functions being continuous?"
- Proof by an anthropic argument: "I say this function is continuous. Am I not wonderful? Hence the function is continuous."
- Proof by a transcendental argument: "This exercise would be meaningless if the function wasn't continuous. Hence Q.E.D."
- Proof by a transcendental argument (alternative): "Let us assume a discontinuous function.
*The whole structure of mathematics crumbles to the ground!*" - Proof by lack of imagination: "What do you mean, discontinuous function? The professor never said nothing about discontinuous functions..."
- Proof by theology: "No, seriously! No-one believes all functions are continuous anymore! It's just that this function is continuous because we need it to be..."

- Proof by herbal remedies (student version): "Oh, man, pi is so totally three. And it's coming through the walls!"
- Proof by a cultural variation: "Herr Doktor, here in Prussia we don't need proofs; we believe when we're told!"
- Proof by another cultural variation: "What do you mean pi ain't three? I saw it on TV!"
- Pi is three. Pi is three. Pi is three. Subliminal proof.

- Proof by emotion: "Look at this child! This poor child! Can you even guess the pain and sadness of her lost childhood if she has to spend her summer toiling with make-up exams!"

*what?*" - Proof by crop circles: "It's a little lopsided, but its circumference divided by diameter is three!"
