…IQ", "violent" to your search query.) If instead you like reading actual source documents and the testimony of people who knew Alan Turing first hand, the preface to The Collected Works of A.M. Turing: Morphogenesis (P. T. Saunders, Editor) was written by P. N. Furbank, his close friend and legal executor, and explicitly endorses Hodge's book in a good light: "Indeed, with the aid of Andrew Hodges's excellent biography, A.M.…

Makes one feel as though we've taken a step backwards from Alan Turing's "The Chemical Basis of Morphogenesis". Consider the "morphogenetic puzzle" of a bi-valved seashell that shuts with perfect water-tight seal. There is a constraint to this design: survival! https://twitter.com/AlainGoriely/status/1207210428344029184

He used lots of heavy math that came so naturally to him, to model plant growth as a reaction-diffusion…

Essentially, one of the first things Turing did when he had regular access to a real computer (and not some lashup being used to break German ciphers) was to use it to simulate how life might arise…

Someone, somewhere, is due to be awarded the Grand Prize Turing Award, for solving Turing's unfinished Morphogenesis problem, and then implementing Turing's original machine on the resulting artificially intelligent 'organism'.

This is an important example, because there is a classic theory of biological pattern formation, or morphogenesis, first formulated by Turing in the 1950s, which lends itself very easily to modeling in CAs, and with a little fine-tuning produces things which look like animal coats, butterfly wings, etc., etc. The…
