Personally I consider any "random" abberations to be symptoms of the hairy dog theorom: you cant comb all the hair to lie flat, somewhere on the spherical dog, you're going to get a cowlick, it is unavoidable
in the meantime, chirality is simply mirror symmetry : curious part to me, is how mirror symmetry works out as one half being the "inside out" version of the other, turn a left handed glove inside out and it will fit the right hand. Maybe points to 4th dimensional stuffs, I never could grok how to turn a sphere inside out without pinching

- ykonstant 5y agoHere are two classic youtube videos on the topic of sphere eversion; they mostly overlap, but I am posting both for double the hilarity in the comment sections :) (the full 21 minute one) https://www.youtube.com/watch?v=wO61D9x6lNY https://www.youtube.com/watch?v=wO61D9x6lNY (the first 10 minutes) https://www.youtube.com/watch?v=sKqt6e7EcCs https://www.youtube.com/watch?v=sKqt6e7EcCs If I remember correctly, I think the 10 minute one has the more hilarious comment section.
