Strangely enough I read that just the other week - we went to a museum that used to be a prisoner of war camp, and one of the exhibits was about the competition the government ran to try and create a 'death ray', and they discovered radar by accident.
I was VERY impressed with the place, we could have done longer there, I initially thought a couple of hours would be more than enough, but we only left when it got too dark.
