The Manhattan Project was a top-secret research and development project that was conducted by the United States during World War II. The project was led by Major General Leslie Groves and involved the collaboration of some of the world's top scientists, including J. Robert Oppenheimer, Enrico Fermi, and Richard Feynman.
The goal of the Manhattan Project was to develop and produce an atomic bomb before Nazi Germany could do so. The project was successful, and the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945. These bombings resulted in the surrender of Japan and the end of World War II.
The Manhattan Project was a massive undertaking that involved the mobilization of thousands of scientists, engineers, and technicians. The project also required the construction of several secret research and production facilities, including the Los Alamos National Laboratory in New Mexico and the Oak Ridge National Laboratory in Tennessee.
The Manhattan Project was a success, but it also came at a great cost. The project cost billions of dollars and resulted in the deaths of thousands of workers. The project also raised serious ethical concerns about the use of atomic weapons.
