  1. The Nielsen-Thurston Classification, discovered by Jakob Nielsen, is a classification of all people named Thurston. Nielsen proved that all Thurstons are isotopic to one of three kinds of Thurstons:

    a) William
    b) Dylan
    c) Not a hyperbolic geometer

    Note that not all geometer Thurstons are actually William or Dylan: most of them are just isotopic to William or Dylan.
