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 ATOM Project The ATOM Project The ATOM Project (est. August 2012) is an international campaign by the Nazarbayev Center of Kazakhstan. The primary goal of the campaign is to build international support for the abolishment of nuclear testing. ATOM stands for "Abolish Testing. Our Mission." The goal is to achieve in force the Comprehensive Nuclear Test Ban Treaty through online petitions and other methods. The campaign is an initiative of the Nazarbayev Center whose mission includes the "promotion of nuclear responsibility, nuclear disarmament, and nuclear nonproliferation according to the vision of President Nursultan Nazarbayev (Kazakhstan)." Kazakhstan has historically been concerned about nuclear
