The origins of the digital universe

Just finished Turing’s Cathedral – a fine and stimulating book about the origins of the computer, the interlinked history of the first computers and nuclear bombs, the role of John von Neumann in all that, the Institute of Advanced Studies (IAS) in Princeton, and much more. It is a very thoroughly researched volume based on archival materials, interviews, etc. Actually, if I have one complaint it is that it is too scrupulous in presenting the background of all primary, secondary and tertiary characters in the story of the computer and in documenting the development of the various buildings at the IAS. For that reason I found the first part of the book a bit tedious. But the later chapters in which the author allows his own ideas about the digital universe to roam more freely are truly inspired and inspiring. It was also quite fascinating to learn that one of the first uses of the digital computer, apart from calculating nuclear fusion processes and trying to predict the weather, has been to run what would now be called agent-based modeling (by Nils Baricelli). Here is my favorite passage from the book: ‘Books are strings of code. But they have mysterious properties – like strings of DNA. Somehow the author captures a fragment of the universe, unravels it into a one-dimensional sequence, squeezes it through a keyhole, and hopes that a three-dimensional  vision emerges in the reader’s mind. The translation is never exact.’ (p.312)
