Examples of common false beliefs in mathematics
Correcting that misunderstanding is crucial to prove that an accumulation point of a net is always the limit of some subnet, which does not hold for sequences. |

What are your favorite puzzles/toys for introducing new mathematical concepts to students?
There is also projective set, a version designed by a graduate student at Waterloo, which requires recognizing lines in five-dimensional projective space over the field with 2 elements. |

The 15 puzzle is a good way of introducing groupoids. |

What are your experiences of handouts in mathematics lectures?
Victor, I agree. What I actually mean is that I want my one hour lecture plus $n-1$ hours reading the book/notes to be more useful for the student than $n$ hours reading the book/notes. |

Do Lie algebroids pull back (along submersions)?
In particular, since in Theo's case $Y \to X$ was a vector bundle, then $phi^{**} A \to Y$ is the ``total space'' of a VB-algebroid $(\phi^{**}A, Y, A, X)$. See section 6.1 on arXiv:0810.0066. Not sure whether this is relevant, but since you mention "in trivialized case comes in pieces", it may. |

That is what <a href="youtube.com/watch?v=WwslBPj8GgI">Eric Mazour</a> does in physics (but it is equally applicable in mathematics). |

If this had been anybody but Ole Hald, I would be very skeptical. |

Why does undergraduate discrete math require calculus?
To back up Noah's claim, I have taught topology and abstract algebra at Mathcamp without calculus as a prerequisite with no problem. |

Examples of undergraduate mathematics separation from what mathematicians should know
I agree with Mike Skirvin about the Jordan/rational canonical forms: they do appear in problems in many areas. Even if they did not appear, I still consider them important just for illustrating the more general concept of "canonical form" (i.e., the choice of a particular representative of each equivalence class in an equivalence relation). |

Examples of common false beliefs in mathematics
That there are two different notions that are called "locally compact" does not help. |
