When I was creating the original list of places in The Geek Atlas there were a few places that caused my heart to beat a little faster just recalling visits to them. One of those places was Bletchley Park.
Bletchley Park combines cryptography, the Second World War and the out-and-out genius Alan Turing. How could I not include Bletchley Park? It's the place Enigma and Lorenz were broken. Enigma is most famous, but I find Lorenz more fascinating because of its use of binary, pseudorandom numbers and and the XOR operation (but that's another story---told in my book).
And now it's been restored to its wartime glory. Yet it is in severe financial difficulty and has recently been denied further funding by the British government. Some months ago I donated as much money as I could afford to help save Bletchley Park.
So, when O'Reilly (the publisher) of my book suggested that they would donate 50p for every copy of my book sold in the UK in the next 12 months I jumped at the chance to help.
So, if you buy The Geek Atlas in the UK you are getting a fascinating book which describes Bletchley Park (and 127 other great places to visit), the Engima and Lorenz codes and Alan Turing's life and work.
And you are helping save this unique site.
