The Yoda of Silicon Valley

For half a century, the Stanford computer scientist Donald Knuth, who bears a slight resemblance to Yoda -- albeit standing 6-foot-4 and wearing glasses -- has reigned as the spirit-guide of the algorithmic realm. He is the author of "The Art of Computer Programming," a continuing four-volume opus that is his life's work. The first volume debuted in 1968, and the collected volumes (sold as a boxed set for about $250) were included by American Scientist in 2013 on its list of books that shaped the last century of science -- alongside a special edition of "The Autobiography of Charles Darwin," Tom Wolfe's "The Right Stuff," Rachel Carson's "Silent Spring" and monographs by Albert Einstein, John von Neumann and Richard Feynman. With more than one million copies in print, "The Art of Computer Programming" is the Bible of its field. "Like an actual bible, it is long and comprehensive; no other book is as comprehensive," said Peter Norvig, a director of research at Google.
