Why is There Peace? — violence is declining, over history, at least in relative terms, though not, one suspects, absolute ones.

This morning, my Dad opened an exhibition in the museum in my home town, of ninety photos taken by my great-grandfather, found (on glass plates) when Dad retired, and recently restored by him via digital photography. Here’s an article on the BBC, including an audio interview with Dad, in which (I think) he sounds fab. Rich voice, Terrence!

Notes: Tony Sale on WW2 codebreaking and Colossus rebuild

Earlier this evening I went to a great lecture by Tony Sale, on “Code Breaking in World War 2″.

He discussed Enigma, and how it was broken, then the Lorenz cipher/machine, and how that was broken, and then the Colossus, leading to the Colossus rebuild project. He should know about this stuff: he started the project.

I took some notes if anyone is interested [PDF, 76Kb] (naturally, these are rough notes, may contain errors, are my own, etc.). You might also want to check out codesandciphers.org.uk which includes a virtual Colossus.
