(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 ...
and Dirac. The institute became the center of a vibrant scientific community that worked on the most pressing problems in physics during the first half of the 20th century. Niels Bohr’s Nobel ...
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 ...
