Little Boy, the bomb dropped on Hiroshima, Japan, on August 6, 1945, had a yield of 15 kilotons. It yielded an explosion equivalent to 20,000 tons of TNT, or 20 kilotons. In an attempt to get scientists to stop openly talking about bomb production, the first atomic bomb was named “Gadget.” It was tested at Trinity on July 16, 1945. It’s a fission bomb that forms the centerpiece of Oppenheimer. In this process, a mass of radioactive isotopes, like Uranium-235 or Plutonium 239, is compressed at high speed, breaking apart the atomic bonds in the isotopes and sending neutrons outwards with tremendous force. The bombs of today are much more powerfulĪt the heart of an atomic bomb of any kind is a fission reaction. Here are three details of nuclear weapons and their development not captured in the film. Los Alamos National Laboratory, where Oppenheimer oversaw the bomb’s development, was founded as part of the atomic bomb effort and today remains an important center of American nuclear weapons research.Īny fuller story of the bomb needs to venture beyond the boundaries of laboratory grounds and test ranges. Sherwin, which offers a thorough portrait. The film draws directly from American Prometheus, a 2005 biography of Oppenheimer by Kai Bird and Martin J. ![]() The film depicts a fairly mainstream understanding of the scientist’s life, triumph, and foibles.īecause Nolan’s camera is kept narrowly focused on Cillian Murphy as Oppenheimer, much of the bomb’s impact and early history is kept largely off screen.
