Hiukan hiukkasfysiikkan oppituntia vlta. 1946. Näin yöllä tosin, mutta sotaahan ei käydä Nukkumatin hiekkalaatikolla.

Eli tapaus Louis Slotin sääteli kriittistä massaa ja kämmäsi ruuvimeisselin kanssa, ollen vainaa 9 päivän kuluttua.
"While lowering the top reflector, Slotin's screwdriver slipped a fraction of an inch, allowing the top reflector to fall into place around the core. Instantly there was a flash of blue light and a wave of heat across Slotin's skin; the core had become supercritical, releasing a massive burst of neutron radiation. He quickly knocked the two halves apart, stopping the chain reaction and likely saving the lives of the seven other men in the laboratory. Slotin's body positioning over the apparatus also shielded the others from much of the neutron radiation. He received a massively lethal dose in under a second and died 9 days later from acute radiation poisoning. The nearest physicist to Slotin, Alan Graves, was watching over Slotin's shoulder and was thus partially shielded by him, receiving a high but non-lethal radiation dose. He was hospitalized for several weeks with severe radiation poisoning, developed chronic neurological and vision problems as a result of the exposure, and suffered a significant shortening of his lifespan, dying of radiation-induced leukemia less than a decade later. The others in the room were far enough away from the assembly to suffer no permanent injuries from the accident."
Atomiaika jyrää. Tuommoisen samaisen 6 kilon plutonium pallon kun imploudaa, niin explosion on sitten historiaa.
