Matt Webb runs a marathon, wins a medal and writes about it in a fashion only Webb could. What person causally drops in Turing patterns while explaining what cramp is? Webb does of course and it is all very interesting. His final words on the experience: “And that’s another lesson I can take more generally which is to try more and if I’m going to commit, then commit faster.“
Also you can read the 1952 Turing article, The Chemical Basis of Morphogenesis here. Turing’s only published writing about Chemistry. At the end of this article Turing writes, “It might be possible, however, to treat a few particular cases in detail with the aid of a digital computer.“
I believe Turing was in Manchester at the time, working on the Manchester Mark 1 at the Computing Machine Laboratory.
