The core was made up of two hemispheres that had to be kept separate, as allowing them to touch would form a critical mass. In a display of bravado, physicist Louis Slotin decided to use a thin screwdriver blade to wiggle them around. As you can imagine, it didn’t go well.
Haroutune Krikor Daghlian, Jr. (May 4, 1921 – September 15, 1945) was an American physicist with the Manhattan Project who accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site facility at Los Alamos National Laboratory in New Mexico, resulting in his death 25 days later.
I think we can all agree that the physicists, engineers, and chemists who worked on the Manhattan Project -- which ultimately ended World War II -- were consummate geniuses and paragons of professionalism. Except they weren't. The demon core of plutonium claimed numerous lives at Los Alamos due to sloppy science.
