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
The History and Adventures of an Atom The History and Adventures of an Atom The History and Adventures of an Atom, by Tobias Smollett, is a novel that savagely satirises English politics during the Seven Years' War. It appears under the guise of a tale from ancient Japan. Pitt the Elder appears as "Taycho", and other politicians, monarchs and nations under a light disguise of made-up names. It includes some comments on Britain's growing problems with its American colonies. The 'atom' is the supposed narrator, a witness to the events and somehow able to communicate them to modern listeners. Smollett is referring back to the ancient Greek
