I'm a mathematician currently working in informatics, and at the same time a grad student researching graph theory.

Awfully sophisticated proof for simple facts
@MichaelBlackmon: Do you have a reference for that claim? This would give me a proof of the corollary that I'm an algebraist. |

Demonstrating that rigour is important
I guess this was in the 20th century. These days you can check quickly with a computer that the sum of the first five million primes is already over pi. |

@BlueRaja: yes, but the calculator will be dead long before that point happens. |

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. |
