Badiou and Mathematics
I see no reason to close. Mathematics is used (and abused) in many ways/areas outside mathematics. It is certainly of interest to mathematicians. About blog discussions: it is true that mathoverflow far from ideal for discussion but it does provide many opportunities for discussions and blogs often cannot compete. I tried to transport a discussion about planar graphs from MO to my blog with little success. There are only few blogs with genuine mathematical discussions. Discussions in MO is like sex in cars; it is a terrible platform, but often it provides the only available opportunity. |

Generalizations of Planar Graphs
I meant algebraiv variety of reak dimension 2k, we can even insist it is a smooth variety. |

Generalizations of Planar Graphs
Dear Konrad, this is indeed an important generalization of planar graphs. (I am not so sure lambda<=3 gives planarity rather than the very related "not having a K_5-minor".) |

What are good non-English languages for mathematicians to know?
Hungarian, of course |

Generalizations of Planar Graphs
Actually, It can be conjectured that k-dimensional startified spaces that can be embedded into Witt 2k-dimensional spaces with vanishing middle homology are already appropriate analogs for planarity. On the other hand in analogy with the fact that every graph can be embedded into some surface I wonder if every k-dimensional stratified space (or simplicial complex) can be embedded into some 2k-dimensional algebraic variety. |

most general way to generate pairwise independent random variables?
There is a large body of literature on constructions of k-wise independent random variables. I suggest to look at Alon and Spencer's book on the probabilistic method. |
