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
BASIC Atom little area on a board, at the expense of greater height. BASIC Atom "Basic Atom" refers to a line of self-contained microcontrollers from Basic Micro. Like the Basic stamp, the Basic Atom line is based upon various microchips pre-programmed with an interpreter, making it easy to change "programs", as they are only "data" being interpreted. A compiler converts a high level language into the interpretive "code" which is then loaded in as data, and run. Basic Atom chips may be added to other projects via the familiar Dual in-line package style, or the higher density TQFP. One small Basic Atom
