Quantization Conditions, 1900-1927
Anthony Duncan, Michel Janssen
We trace the evolution of quantization conditions from Planck's introduction of a new fundamental constant (h) in his treatment of blackbody radiation in 1900 to Heisenberg's inter…
Introduction to Volume 15 of The Collected Papers of Albert Einstein. The Berlin Years: Writings and Correspondence June 1925 - May 1927
Diana Kormos Buchwald, József Illy, A. J. Kox +12
This volume covers one of the most thrilling two-year periods in twentieth-century physics, as matrix mechanics - developed chiefly by W. Heisenberg, M. Born, and P. Jordan - and w…
The Stark effect in the Bohr-Sommerfeld theory and in Schrödinger's wave mechanics
Anthony Duncan, Michel Janssen
The explanation of the first-order Stark effect in hydrogen by Epstein and Schwarzschild in 1916 was seen as a great success for the old quantum theory. Yet, it also revealed some…
The trouble with orbits: the Stark effect in the old and the new quantum theory
Anthony Duncan, Michel Janssen
The old quantum theory and Schrödinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line splittings in the first-order Stark effect in hydr…
(Never) Mind your p's and q's: Von Neumann versus Jordan on the Foundations of Quantum Theory
Anthony Duncan, Michel Janssen
In two papers entitled "On a new foundation [Neue Begründung] of quantum mechanics," Pascual Jordan (1927b,g) presented his version of what came to be known as the Dirac-Jordan sta…
Pascual Jordan's resolution of the conundrum of the wave-particle duality of light
Anthony Duncan, Michel Janssen
In 1909, Einstein derived a formula for the mean square energy fluctuation in black-body radiation. This formula is the sum of a wave term and a particle term. In a key contributio…
