__How an atomic bomb works__

code Nuclear weapons are devices that use the energy contained within the Nuclei of atoms to create massive explosions. This energy may be released by the fission or the fusion of atoms. "There is at least one defense against the atomic bomb. That defense lies in our mastering this science of human relationships all over the world. It is the defense of tolerance and of understanding, of intelligence and thoughtfulness" As Harry S. Truman said. code code The huge power of an atomic bomb comes from the forces holding each individual atom of a substance together. These forces act over tiny distances deep within the atom itself. Every atom of every substance that exists is held together by them. code code A bomb cannot be made simply by putting a piece of uranium larger than critical mass into a casing. The simplest possible atomic bomb is one of the types dropped on Hiroshima. It is known as a gun-type bomb since it actually contains a type of gun. code code Nuclear fusion cannot occur spontaneously. Normally two Nuclei repel each other because they both carry a positive electric charge, so if they are to fuse, they must be forced together. code code code code
