Turing (A Novel about Computation)


Our hero is Turing, an interactive tutoring program and namesake (or virtual emanation?) of Alan Turing, World War II code breaker and father of computer science. In this unusual novel, Turing's idiosyncratic version of intellectual history from a computational point of view unfolds in tandem with the story of a love affair involving Ethel, a successful computer executive, Alexandros, a melancholy archaeologist, and Ian, a charismatic hacker. After Ethel (who shares her first name with Alan Turing's mother) abandons Alexandros following a sundrenched idyll on Corfu, Turing appears on Alexandros's computer screen to unfurl a tutorial on the history of ideas. He begins with the philosopher-mathematicians of ancient Greece—"discourse, dialogue, argument, proof...can only thrive in an egalitarian society"—and the Arab scholar in ninth-century Baghdad who invented algorithms; he moves on to many other topics, including cryptography and artificial intelligence, even economics and developmental biology. (These lessons are later critiqued amusingly and developed further in postings by a fictional newsgroup in the book's afterword.) As Turing's lectures progress, the lives of Alexandros, Ethel, and Ian converge in dramatic fashion, and the story takes us from Corfu to Hong Kong, from Athens to San Francisco—and of course to the Internet, the disruptive technological and social force that emerges as the main locale and protagonist of the novel.

Alternately pedagogical and romantic, Turing (A Novel about Computation) should appeal both to students and professionals who want a clear and entertaining account of the development of computation and to the general reader who enjoys novels of ideas.

About the Author

Christos H. Papadimitriou is C. Lester Hogan Professor of Computer Science at the University of California, Berkeley and a member of the National Academy of Engineering and the American Academy of Arts and Sciences. He is the author of many books on computational theory.


“...inventively interwoven with a romance and intellectual mystery.”—Sally Abbott , San Francisco Chronicle
“What's most delightful about Turing is the charmed glow that Papadimitriou's prose sheds all around.”—George Scialabba, Boston Sunday Globe


“Combining storytelling and brilliant exposition in the Enlightenment tradition, Christos Papadimitriou's Turing is at once a moving postmodern love story and one of the best introductions to theoretical computer science available, an enchanting offer to the intelligent reader.”
Apostolos Doxiadis, author of Uncle Petros and Goldbach's Conjecture
“This is a delightful book in which science and fiction meet literature and politics. It makes you feel and understand what creativitiy means and how it relates to the culture of society. And it is great fun!”
Manuel Castells, Wallis Annenberg Professor of Communication Technology & Society, University of Southern California, Author of The Internet Galaxy
Turing sets new standards for the popular exposition of computer science. It is also a very funny book.”
Donald E. Knuth, Professor Emeritus of the Art of Computer Programming, Stanford University
