拓扑学就是硬射函数是连续函数， continuous transformation function。
但你不管是怎样的硬射函数，看起来多么 definable，你最终要走到两个实数集之间的
硬射，也就是定义域实数集和值域实数集之间的硬射。
而两个实数集之间的硬射，归根到底就是 axiom of choice 。 而实数集之间的 axiom
of choice ，是没有 definable 的（图灵机刹得住车的）choice function。这就带
来了到底是硬射美胸系花，还是硬射美腿系花，这样的硬射选择困难，因为 choice
function is non-definable（图灵机刹不住车，硬而不射），而最终让数学成为哲学
，或者说，美学。
哥们侃问题要侃本质 。。。
