Alan Turing: His Work and Impact

Number of Pages: 

Although he only lived 41 years, Alan Turing had a significant effect on the world. Through his work in decoding the German military message in World War II, he arguably did more to keep Great Britain from losing the war in the dark time after the withdrawal at Dunkirk than anyone other than Winston Churchill. His concept of the simple Turing Machine not only solved one of the famous Hilbert problems, it put forward a theoretical model for computers that can still be used to study the power of the fastest supercomputers.

This thick volume is a collection of Turing’s most significant papers along with commentary by people that appreciated and furthered his ideas. What will astound even the people that know the work of Turing is the breadth of his interests and depth of his competence. The list of contributors for the commentaries is impressive, including Turing biographer Andrew Hodges, logicians from Martin Davis to Gregory Chaitin, number theorists such as Andrew Odlyzko, computer scientists from Lenore Blum to Stephen Wolfram, philosophers and biologists whose name I probably should recognize as well. Included here are some of the classic works on machine game playing, computational biology, and artificial intelligence. What’s more, they can still be used to educate, especially with the added commentary.

As early as the late 1940s Turing was putting forward serious ideas about the future of computing, even though at the time computers were relatively incapable hulks. Although the Turing test for artificial intelligence is no longer considered proof positive of machine intelligence, there is no question that any intelligent machine would have to be able to pass it.

In some ways a person that thought decades ahead of his time, Alan Turing died much too young. Whenever the topic is the social cost of prejudice, there is no stronger argument against it than citing the case of Turing, a man that was most likely hounded to suicide for his being gay at a time when it was a criminal offense. If you doubt the size of our loss, simply scan the subject lines in the table of contents of this book. 

Charles Ashbacher splits his time between consulting with industry in projects involving math and computers, teaching college classes and co-editing The Journal of Recreational Mathematics. In his spare time, he reads about these things and helps his daughter in her lawn care business.
