Hydrogen atom (non relativistic) hydrogen atom was solved for the first time within Feynman's path integral formulation of quantum mechanics. This work greatly extended the range of applicability of Feynman's method. Hydrogen atom A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. In everyday life on Earth, isolated hydrogen atoms (called "atomic hydrogen") are extremely rare. Instead, hydrogen tends to combine with other atoms
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.
