Computionally efficient vertex enumeration for (convex) polytopes
How is the polytope defined? Is it given as an intersection of half-planes? If so, can this problem be transformed to the dual problem of enumerating all the facets of the convex hull if the vertices are given? |

Mathematical habits of thought and action which would be of use to non-mathematicians
So as a mathematician, I should be paid more if I get fatter? See the recent Dilbert strips: dilbert.com/series/63 |

Too old for advanced mathematics?
You may consider asking this question on Mathematics Educators SE (which is a new site that didn't exist yet when you posted this), as matheducators.stackexchange.com/help/on-topic indicates questions about learning mathematics are on-topic there. |

Time for Langton's ant to cover a “square” torus
In the pictures showing how often the ant appears on a square, could you give a legend for what color means what frequency? |

Correlation between two continuous-time stochastic processes
This question seems to general. Could you be more specific, like, give the particular processes you're interested in. |

Schoenberg's Rational Polygon Problem
@AaronMeyerowitz: yes, it is open, mathoverflow.net/a/100449/5340 gives a reference to a paper. |

Do good math jokes exist?
Downvoting because this joke is already in an earlier answer mathoverflow.net/a/3441/5340 |

Oh come on! mathoverflow.net/a/2254/5340 already has the Cauchy joke. |
