Alan Turing

Definition

Alan Turing was a British mathematician, logician, and computer scientist who is considered one of the founding figures of computer science and artificial intelligence. He is best known for his role in breaking the Enigma code during World War II, as well as for formulating concepts that laid the groundwork for modern computing, such as the Turing machine, which is a theoretical model that defines computation and algorithms.

5 Must Know Facts For Your Next Test

1. Alan Turing developed the Turing Test, a criterion for determining whether a machine exhibits human-like intelligence based on its ability to engage in conversation indistinguishable from a human.
2. His work during World War II at Bletchley Park not only shortened the war but also established him as a pioneer in cryptanalysis.
3. Turing's 1936 paper 'On Computable Numbers' introduced the concept of a universal machine, which led to the development of modern computers.
4. Despite his groundbreaking contributions, Turing faced severe discrimination due to his homosexuality, which led to his tragic death at a young age.
5. In 2013, Turing was posthumously pardoned by the British government for his conviction of 'gross indecency,' acknowledging the injustice he faced.
