🕵️ The Spy Who Counted Everything
A codebreaker's obsession with counting gave us modern computing.
Alan Turing, the British mathematician who cracked the Enigma code during WWII, was fascinated by an apparently simple question: what does it mean for a number to be computable? In 1936 he imagined an abstract machine with an infinite paper tape, a read-write head, and a set of rules. That thought experiment, the Turing machine, became the foundation of computer science.
Turing later turned to biology, publishing a 1952 paper on morphogenesis explaining how patterns like stripes and spots arise from chemical reactions. He proposed a reaction-diffusion model, now called a Turing pattern, that still guides research into animal markings and coral growth.
💡 One curious question about counting led to the machine your phone runs on.
