@Ho Chung Siu, do you happen to have a copy of that paper anywhere accessible? |

What is the high-concept explanation on why real numbers are useful in number theory?
This is totally tangential but I just want to say I strongly disagree with the sentiment of the first sentence. If statements and proofs were typically "in the same world", math would be so dull. Dystopia. |

Motivation behind Tutte's 1-factor theorem
I changed the question's title to better correspond to its content. You don't appear to be interested in the historical development of the theorem, but rather the motivation behind this characterization. Perhaps a better way to phrase the question would be to ask, is there any algorithmic or theoretical advantage to this (rather daunting) condition. |

Is “second-countable implies separable” equivalent to the Axiom of countable Choice?
Surely this requires only the axiom of countable choice? |

How many finite simple groups of order $p+1$?
n!/2-1 is prime for n=5, 6, 9, 31, 41, 373 ... (sequence A082671 on the OEIS). Is it known if this sequence is finite? |

Ingenuity in mathematics
To complete the triviality of the situation, after your audience proposes a bunch of complex strategies, propose an alternative game whereby after "STOP" it's the last card in the deck that gets turned over. Everyone sees that this game is strategy-indifferent, and then you deliver the coup de grace... I've used this several times in math circles. Gets them every time. |
