A "Kirkus Reviews" Best Book of 2012
In this revealing account of how the digital universe exploded in the aftermath of World War II, George Dyson illuminates the nature of digital computers, the lives of those who brought them into existence, and how code took over the world.
In the 1940s and '50s, a small group of men and women--led by John von Neumann--gathered in Princeton, New Jersey, to begin building one of the first computers to realize Alan Turing's vision of a Universal Machine. The codes unleashed within this embryonic, 5-kilobyte universe--less memory than is allocated to displaying a single icon on a computer screen today--broke the distinction between numbers that "mean" things and numbers that "do" things, and our universe would never be the same. "Turing's Cathedral "is the story of how the most constructive and most destructive of twentieth-century inventions--the digital computer and the hydrogen bomb--emerged at the same time.
We based our evaluation of book condition on the following criteria:
* New: Just like it sounds. A brand-new, unused, unread copy in perfect condition.
* Like New: An apparently unread copy in perfect condition. Dust cover is intact; pages are clean and are not marred by notes or folds of any kind.
* Very Good: A copy that has been read, but remains in excellent condition. Pages are intact and are not marred by notes or highlighting, but may contain a neat previous owner name. The spine remains undamaged.
* Good: A copy that has been read, but remains in clean condition. All pages are intact, and the cover is intact. The spine may show signs of wear. Pages can include limited notes and highlighting, and the copy can include "From the library of" labels or previous owner inscriptions.
* Acceptable: A readable copy. All pages are intact, and the cover is intact (the dust cover may be missing). Pages can include considerable notes--in pen or highlighter--but the notes cannot obscure the text.
