By Andrew Hodges (auth.), Christof Teuscher (eds.)
Alan Turing's primary contributions to computing resulted in the improvement of contemporary computing expertise, and his paintings keeps to motivate researchers in computing technology and past. This ebook is the definitive number of commemorative essays, and the celebrated members have services in such diversified fields as synthetic intelligence, normal computing, arithmetic, physics, cryptology, cognitive reports, philosophy and anthropology.
The quantity spans the full wealthy spectrum of Turing's lifestyles, learn paintings and legacy. New gentle is shed at the way forward for computing technology via visionary Ray Kurzweil. outstanding contributions come from the thinker Daniel Dennett, the Turing biographer Andrew Hodges, and the prestigious truth seeker Martin Davis, who offers a primary severe essay on an rising and debatable box termed hypercomputation. a distinct function of the ebook is the play through Valeria Patera which tackles the scandal surrounding the final apple, and provides as an enigma the lifestyles, loss of life and future of the guy who did rather a lot to decipher the Enigma code in the course of the moment global battle.
Other chapters are smooth reappraisals of Turing's paintings on computability, and take care of the foremost philosophical questions raised via the Turing attempt, whereas the publication additionally comprises essays addressing his much less famous rules on Fibonacci phyllotaxis and connectionism.
