I'm sold. I'm not very good at maths, but modding the image of ∂ₙ by the kernel of ∂ₙ₊₁ is something I "understand" in the Von Neumann sense. That is to say I've become "used to it" and now it seems to me utterly obvious. (I accept Dunning-Kruger objections may apply.) Anyway, where is this Topological Data Analysis that's going to be easy for me?
