...reactor was beautifully simple. It was called a "pile," and it was literally that-a 500-ton pile of carefully machined bricks made of pure graphite. Imbedded in some of the bricks, in a precisely calculated pattern, were little cubes of uranium or uranium oxide. Long control rods, plated with the metallic element cadmium, were so set up that they could be withdrawn from, or inserted into, deep holes in the graphite...
That is all there was to it. The operation of the pile depended on natural properties of 1) uranium, which normally emits neutrons at a steady rate, 2) graphite, which slows neutrons down but does not absorb them, and 3) cadmium, which absorbs neutrons very effectively. As the control rods were withdrawn-so the experimenters figured-fewer of the neutrons from the uranium would be absorbed, and therefore more fission would occur. At some point of withdrawal, fission would be producing new batches of neutrons faster than the cadmium would be absorbing them. Result: a chain reaction...
...world like a Red Cross Evacuation Center," sneered one of the leaflets. "The whole idea of 'decorating' the dance with 'relaxing' mattresses and bedding is so ludicrous that we have to laugh...As a matter of fact, I can't think of anything more 'decorative' than a pile of grubby, Harvard-issue mattresses...

...nearly 70 now-a dark, brooding, badger-faced man living in near-total oblivion in the enormous stone pile that is Spandau prison. But in May 1941, when Rudolf Hess suddenly landed in a cow pasture in Scotland and asked to see the Duke of Hamilton, the Deputy Führer of the Third Reich was full of high hope...
