Manhattan Project: Scientists
built 113 days ago
The origins of the Manhattan Project can be traced to the scientific laboratories of Britain and Europe in the early 1900s. At that time, the basic unit of matter, the atom, was viewed as solid and impossible to divide. The startling discoveries of radium, the X ray, the electron, proton, and neutron, and alpha, beta, and gamma rays... alerted scientists to the existence of a “subatomic” world. As British physicist Ernest Rutherford and Danish physicist Niels Bohr suggested, instead of being solid, the atom resembled a “miniature solar system.” Within the atom negatively charged electrons orbited positively charged protons and electrically neutral neutrons in the atom’s nucleus.

Not all the scientists working on the Manhattan Project agreed with this. Szilard, James Franck, and a majority of the scientists at the Chicago laboratory asserted that military use against a Japanese city was unnecessary and immoral and would start a postwar nuclear arms race. In response to their petition for a test demonstration and warning for Japan, a special scientific advisory committee—composed of Fermi, Lawrence, Oppenheimer, and Arthur Compton—met on 16 June but rejected the idea of a noncombat demonstration (the bomb might not explode, and even if it did, its lethality would not be adequately demonstrated).

This essay entails the work that was done in the Manhattan Project. It mainly focuses on the preparations and the work of the diverse group of scientists who came up with the idea.
