Turing failed to pass, though, and would have to spend another year at Sherborne. Despite that fact, Turing would later say that those few winter days at Cambridge in 1929 were the best in his life. Death of a Friend However, this special time in two young lives would not last. During the Christmas and New Year’s break of 1929–30, Turing and Morcom worked on various projects and exchanged letters, reporting results and comparing academic plans. At the end of the break, the new term began smoothly enough, but as Hodges recounts, on February 6, 1930, after they had gone 12 AlAn Turing to a concert together, and Turing had returned to his room, during the night he awoke suddenly.

Finally, in the 1970s handheld calculators replaced them, especially as the microchip-driven pocket calculator became more and more sophisticated. Mechanical Calculators Mechanical digital calculators also advanced in the 17th century. The German scholar and inventor Wilhelm Schickard (1592–1635) built the first successful cogs-and-wheels calculating machine. He described it in a letter to the famous astronomer Johannes Kepler (1571–1630): What you have done by calculation I have just tried to do by way of mechanics.

O. Hoppe/CORBIS) United States. Many of them stopped by Cambridge to give lectures and courses before traveling on, and some of them chose to stay. This wave of flight from the rising tide of totalitarianism brought the mathematics issues of the day right to Turing’s doorstep. The graceful towers of one of Britain’s two greatest universities (the other being Oxford) gave shelter, and in turn, the students in Turing’s class inherited a giant intellectual legacy—from the best of the best of European universities.
