I don’t actually know much about topology, apart from the background level, and the edge-case of graph theory <{filename}graph_theory.rst>`_. Often the very coarse topology of networks is of interest, or the more metaphorical knowledge topology, or actual continuous fields or knots or whatever. Sometimes I care about the induced topology of a metric convergence, but this is hardly fancy stuff.

Apparently grown-up topology has uses too though?
