From the reviews:
"This is a wonderful book, which does deliver what it promises; and that is no small feat. … One of the things that I like in the book is its sense of fun. … It is beautifully written and contains a very nice survey of an area that deserves to be better known to mathematicians. … Finally, the book is beautifully produced, abundantly illustrated … . I recommend it to everyone interested in any aspect of Turing’s legacy … ." (S.C. Coutinho, The Mathematical Gazette, Vol. 89 (516), 2005)
"This remarkable volume is the serendipitous result of Christof Teuscher realizing in September 2001 that Turing would have celebrated his 90th birthday on June 23, 2002. … This book is the definitive collection of commemorative essays, and the distinguished contributors have expertise in such diverse fields as artificial intelligence, natural computing, mathematics, physics, cryptography, cognitive studies, philosophy and anthropology. The volume spans the entire rich spectrum of Turing’s life, research work and legacy." (Cryptologia, Vol. 29 (1), 2005)
"It is difficult to find the superlatives to describe the wonderful job the contributors to this book have done. Every chapter is written in an expository fashion, demanding very little in the way of background knowledge from any scientifically minded reader. The range of topics is also impressive … . I unreservedly recommend this book to anyone even slightly interested in the continuing role of Turing’s work in the development of computer science in particular, and ideas in general." (John L. Casti, nature, Issue 428, 2004)
Alan Turing's fundamental contributions to computing led to the development of modern computing technology, and his work continues to inspire researchers in computing science and beyond. This book is the definitive collection of commemorative essays, and the distinguished contributors have expertise in such diverse fields as artificial intelligence, natural computing, mathematics, physics, cryptology, cognitive studies, philosophy and anthropology.
The volume spans the entire rich spectrum of Turing's life, research work and legacy. New light is shed on the future of computing science by visionary Ray Kurzweil. Notable contributions come from the philosopher Daniel Dennett, the Turing biographer Andrew Hodges, and the distinguished logician Martin Davis, who provides a first critical essay on an emerging and controversial field termed hypercomputation. A special feature of the book is the play by Valeria Patera which tackles the scandal surrounding the last apple, and presents as an enigma the life, death and destiny of the man who did so much to decipher the Enigma code during the Second World War.
Other chapters are modern reappraisals of Turing's work on computability, and deal with the major philosophical questions raised by the Turing Test, while the book also contains essays addressing his less well-known ideas on Fibonacci phyllotaxis and connectionism.
