We read these,and we simply had to share them.36 Humorous Methods of ProofAnyone who has ever fought with a proof will love this list. Enjoy! themathlab.com staff |
||

1 | Proof by obviousness | "The proof is so clear that it need not be mentioned." |

2 | Proof by general agreement | "All in favor?..." |

3 | Proof by imagination | "Well, we'll pretend it's true..." |

4 | Proof by convenience | "It would be very nice if it were true, so..." |

5 | Proof by necessity | "It had better be true, or the entire structure of mathematics would crumble to the ground." |

6 | Proof by plausibility | "It sounds good so it must be true." |

7 | Proof by intimidation | "Don't be stupid; of course it's true." |

8 | Proof by lack of sufficient time | "Because of the time constraint, I'll leave the proof to you." |

9 | Proof by postponement | "The proof for this is long and arduous, so it is given in the appendix." |

10 | Proof by accident | "Hey, what have we here?!" |

11 | Proof by insignificance | "Who really cares, anyway?" |

12 | Proof by mumbo-jumbo | |

13 | Proof by profanity | (example omitted) |

14 | Proof by definition | "We define it to be true." |

15 | Proof by tautology | It's true because it's true." |

16 | Proof by plagiarism | "As we see on page 289,..." |

17 | Proof by lost reference | "I know I saw it somewhere..." |

18 | Proof by calculus | "This proof requires calculus, so we'll skip it." |

19 | Proof by terror | When intimidation fails... |

20 | Proof by lack of interest | "Does anyone really want to see this?" |

21 | Proof by illegibility | |

22 | Proof by logic | "If it is on the problem sheet, then it must be true!" |

23 | Proof by majority rule | "Only to be used if general agreement is impossible." |

24 | Proof by clever variable choice | "Let A be the number such that this proof works..." |

25 | Proof by tessellation | "This proof works the same as the last." |

26 | Proof by divine word | "...And the Lord said, 'Let it be true,' and it was true." |

27 | Proof by stubbornness | "I don't care what you say-it is true!" |

28 | Proof by simplification | "This proof reduces to the statement 1+1=2." |

29 | Proof by hasty generalization | "Well, it works for 17, so it works for all real numbers." |

30 | Proof by deception |
"Now everyone turn their backs..." |

31 | Proof by supplication | "Oh please, let it be true." |

32 | Proof by poor analogy | "Well, it's just like..." |

33 | Proof by avoidance | Limit of proof by postponement as it approaches infinity |

34 | Proof by design | If it's not true in today's math, invent a new system in which it is. |

35 | Proof by authority | "Well, Ruth Kraus says it's true, so it must be!" |

36 | Proof by intuition | "I just have this gut feeling..." |
