This particular link seems new indeed. There have been other links listed on HN in the past. One that came back a few times is on renormalization group theory (actually a semigroup). Currently my new angle of attack is to check what people have to say who come from a representation theory angle. I also liked this paper by Persi Diaconis a lot: http://statweb.stanford.edu/~cgates/PERSI/papers/The%20MCMC%20Revolution.pdf http://statweb.stanford.edu/~cgates/PERSI/papers/The%20MCMC%... I also like that on his wikipedia page (https://www.wikiwand.com/en/Persi_Diaconis https://www.wikiwand.com/en/Persi_Diaconis) it's stated that: According to Martin Gardner, at school, Diaconis supported himself by playing poker on ships between New York and South America. Gardner recalls that Diaconis had "fantastic second deal and bottom deal". :-)
