I'm a lecturer of mathematics at the University of the South Pacific. My research interests are in algebraic topology and metric geometry.

Finite intersection of open sets @BrianM.Scott how true! everything was perfect up to the unnecessary bracketed remark. Good spotting! |

Finite intersection of open sets yes, this proof is perfectly fine. |

Analysis and categories @ZhenLin I'm not sure these notions relate to what OP wanted. The "continuous" in "continuous functor" has nothing to do with any metric or topological notion. Categories enriched in/internal to Top are more relevant to homotopy theory. But please, I'll interested to hear your opinion about how else the question can be interpreted, perhaps by adding your own answer. |

Analysis and categories I suggest you start then by reading Lawvere's paper "Metric spaces, generalized logic, and closed categories" available in the reprints section of TAC. At the same time you can look at Grandis' papers on the fundamental category of a directed topological space. Quantaloid enriched categories (e.g., Stubbe's work) is also relevant). |

Is the square root of 2 really an irrational number? we can only draw approximations of such perfect shapes, so there is indeed nothing to explain. |
