Prior to World War II, while studying cryptology at Princeton College, Turing constructed an electromechanical binary multiplier, supposedly built upon a wooden breadboard taken from the kitchen of his lodgings. But Turing continued to work towards a mechanical brain, using the burgeoning electronics available. The Turing machine remained theoretical, way ahead of the level of technology available. Such universal computers as the Turing machine are the basis for all smartphones, laptops, and the Internet. “ It is possible to invent a single machine which can be used to compute any computable sequence.” He achieved this by taking the pure mathematics required back to first principles in order to teach his “Turing” machine how to identify whether a specific mathematical theorem was essentially incomputable. In his seminal Computable Numbers paper, first published in 1936, Turing conceived of a mechanical computing device, vastly superior to human capabilities, able to compute the vast numbers of mathematical calculations needed to solve the Entscheidungsproblem-a problem that had been stumping the mathematical world for the previous decade Turing MachineĪ completely original mathematical thinker, fellow of King’s College, Cambridge, and Olympic-class marathon runner, Turing created a theoretical machine that changed the course of history. This can be seen as the start of the search for Artificial Intelligence. He joins a select group including politician Sir Winston Churchill (£5), writer Jane Austin (£10) and painter Joseph Turner (£20), as the faces of these new polymer bank notes – designed for greater security and resilience.Īlan Turing’s lasting legacy is the Turing Test (which he dubbed The Imitation Game – the title of the 2014 film loosely based on his life) from his 1950 paper “Computing Machinery and Intelligence”, where he hypothesised “ A computer would deserve to be called intelligent if it could deceive a human into believing that it was human“.
