This book celebrates the 90th anniversary of the birth of Alan Turing by bringing together a large set of essays on topics as diverse and colourful as the work and life of the man himself. Turing's fundamental contributions to computing kick started the modern computing era. However, he also made early and outstanding contributions to artificial intelligence, artificial neural networks, morphogenesis, cryptology and the philosophy of mind. The book touches on all these areas and includes contributions from luminaries such as Martin Davis, Daniel Dennett, Andrew Hodges, Douglas Hofstadter and Ray Kurzweil. The book also contains some essays on contemporary topics related to Turing's work such as the controversial area of so-called hypercomputation. While many of the essays are advanced, the material remains accessible and interesting. Turing had a strikingly original and whimsical imagination - reflecting this, and unlike many books on technical topics, this one includes some of the kind of speculation that is bound to fire the imagination of readers. Will computers outstrip human intelligence, and when might it happen? Will we become more like computers, or will they become more like us? Ninety years on from the birth of Alan Turing such issues are more relevant and pressing than ever, and this book makes an excellent advanced introduction to the breadth of Turing's work.
