    Or saying that the only global maps we should accept are ones projected onto spheres. Same thing for partial global maps above a certain size threshold (projected onto partial spheres).

    I’m curious what that threshold is. Like how long do North/South roads need to be before there’s a non-trivial divergence towards the equator? How far do parallel East/West roads need to be before one is noticeably longer if measured from the same longitudes?

  Looks like I just failed the “responsible adult” test for more than half my life!

  People know about what non-Euclidean means? Wow, do they also know about manifolds?

  the secret is that all spaces are actually euclidean, due to the whitney embedding theorem.

  (not really though. i just wanted to take my turn at improperly stating famous math results on the internet.)
