dinosaurspen: Mathematician and pioneering software developer Phyllis Cady Johnson (right) and two unknown women working on an IBM calculating machine, date unknown. Johnson specialized in nuclear mathematics, first working at Lawrence Livermore Laboratory and later Oak Ridge National Laboratory, where she worked on the Manhattan Project and later went on to a career developing scientific software for the Atomic Energy Commission.
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.
In 1943, the top scientists from the United States and other nations gathered in Los Alamos, NM for the Manhattan Project. Among them was physicist Hugh Bradner. With informal permission from the U.S. Army, he shot a collection of home movies of life in a place that officially didn't exist, and of people working on a project that ultimately changed history. His footage represents the only look at life in the Los Alamos area during that time. LA-UR 11-4449.
