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
Captain Atom which returns Captain Atom to his usual self (if somewhat confused). In 2005/2006, Captain Atom appears in a nine-part limited series entitled "Captain Atom: Armageddon" under DC's Wildstorm imprint. Captain Atom's sacrifice in "Superman/Batman" sends him to the WildStorm universe for the duration of the series. In this title, he wears a yellow/red outfit that was first seen in the 1996 "Kingdom Come" limited series. At the moment of his apparent death, Captain Atom experiences a time-shift coinciding with his 2005 appearance in "Superman/Batman", resulting in his arrival in the Wildstorm Universe. He quickly gets into a fight with an
