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
Mister Atom Mister Atom Mister Atom is a fictional comic book supervillain, a radioactive robot who is regularly seen as an enemy of Captain Marvel. Mister Atom first appeared in "Captain Marvel Adventures" #78 and was created by Otto Binder and C. C. Beck. Mister Atom was created by Dr. Charles Langley in a story in "Captain Marvel Adventures" #78. His body was constructed first, and then Langley charged the robot with radioactive energy. The spark that gave the robot life also ended the life of his creator. Super-charged with a nuclear reactor and armed with a deadly mind, Mister Atom went
