Exotic atom to weak, electromagnetic and gravitational forces, muonic atoms are governed to very high precision by the electromagnetic interaction. Since a muon is more massive than an electron, the Bohr orbits are closer to the nucleus in a muonic atom than in an ordinary atom, and corrections due to quantum electrodynamics are more important. Study of muonic atoms' energy levels as well as transition rates from excited states to the ground state therefore provide experimental tests of quantum electrodynamics. Muon-catalyzed fusion is a technical application of muonic atoms. A "hadronic atom" is an atom in which one or more of the
Empire of the Atom is kept alive because one of the atom priests wants to conduct an experiment to see what will happen if the boy, unlike other mutant children, is given the full education of an atom priest. In his teens the mutant boy Clane helps his father win a war with Mars. He also continues his studies while his grandfather, who is Lord Leader, and his tutors protect him from the Machiavellian intrigues swirling around him, especially those of his grandmother Lydia. Reaching his majority, Clane turns his estate into a laboratory where he can test new inventions and machines that he
