(The leftmost number is the principal quantum number, much like the discrete but increasing circular orbits of the Bohr atom.) Conventional quantum mechanics didn't have such transitions, and Dirac's ...

In 1913, Neils Bohr proposed that electrons in an atom orbit ... In the same year, Paul Dirac extended Schrödinger’s work by introducing Dirac notation. He also introduced the Dirac equation ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is ...

These ideas of Einstein and Bohr flatly contradicted basic principles ... (In 1925, Heisenberg was 24, Paul Dirac was 23, while “old man” Erwin Schrödinger was 38. Heisenberg got the physics ...

Cette équation décrit le comportement de particules élémentaires de spins demi-entiers, comme les électrons. Dirac cherchait à transformer l'équation de Schrödinger afin de la rendre invariante par ...
