Module 4: Nuclear Physics
... As we have shown, the nucleus of a single atom could be the source of considerable energy. If the nucleus could be split so as to release this energy it could be used to generate power. Therefore, if the energy from millions of atoms were released it would be a great source of power. This thinking i ...
