by George Dyson (2012). Long, detailed and meticulously researched (and footnoted) historical account of the origins of computing in World War II and in the race to build Fission and Fusion bombs. Written for historical techno-geeks, the book is centered around John von Neumann and the Institute for Advanced Study in Princeton and includes John Bigelow – the engineer who actually built MANIAC, the IAS machine (built after ENIAC at University of Pennsylvania) – Alan Turing, Edward Teller and others (this account completely leaves out non Anglo-American contributors, such as Konrad Zuse in Germany). At times poetic, the book deeply delves into the origin of programming, Monte Carlo simulations (to keep track of neutrons splitting uranium atoms), and the unreliability of the individual components making up the computer and its memory (a major concern at the time). The five sets of problems studied on MANIAC were nuclear explosions, shock and blast waves, meteorology and biological and stellar evolution. Random-access memory consisted of the two-axis deflection of an electron beam on a 32 by 32 grid of an 5 inch wide cathod-ray tube with a 24 microsec read-out time. . They used 40 such tubes for a total address space of 40x32x32, that is, 40 kilobits!
