1. Turing developed the concept of the Turing Test as a criterion of intelligence, suggesting that if a machine can engage in conversation indistinguishable from a human, it could be considered intelligent.
2. His work on breaking the Enigma code during World War II is credited with saving countless lives and shortening the war in Europe.
3. Turing's 1936 paper introduced the notion of computable numbers and formalized the idea of algorithms, influencing how we understand computation today.
4. He was prosecuted for homosexuality in 1952, leading to his tragic death in 1954, an event that has since sparked discussions about ethics in science and society.
5. Turing's legacy includes not only contributions to mathematics and computing but also the establishment of the field of artificial intelligence, influencing future generations of scientists and engineers.

Review Questions

• How did Alan Turing's concept of the Turing machine contribute to the understanding of computation and algorithms?
