Nidottu - Petzold, Charles - Programming Legend Charles Petzold unlocks the secrets of the extraordinary and prescient 1936 paper by Alan M. Turing Mathematician Alan Turing invented an imaginary computer known as the Turing Machine; in an age before computers, he explored the concept of what it meant to be computable , creating the field of computability theory in the process, a foundation of present-day computer programming. The book expands Turings original 36-page paper with additional background chapters and extensive annotations; the author elaborates on and clarifies many of Turings statements, making the original difficult-to-read document accessible to present day programmers, computer science majors, math geeks, and others. Interwoven into the narrative are the highlights of Turings own life: his years at Cambridge and Princeton, his secret work in cryptanalysis during World War II, his involvement in seminal computer projects, his speculations about artificial intellig
