I was looking for some trivia to write for today since it is Pi Day. Like for example, how to calculate the n-th digit of Pi (in base16). Or how to locate your birthdate in a π sequence. Here is an example for Georgios Papanikolaou and one for Albert Einstein. I found a book on category theory. Or how from searching how to calculate π digits you end up through random clicking to the PSLQ Algorithm (I do not even remember how now). Interesting stuff one rarely gets the chance to get exposed to. Or why tau trumps pi. But I really lack the energy for a proper post today. So it is just links and a piece of art:
