Einstein and the Perihelion Motion of Mercury
Michel Janssen, Jürgen Renn
On November 23, 2021, the Einstein-Besso manuscript on the perihelion motion of Mercury will be auctioned at Christie's. Expected to fetch around $3M, it promises to be the most ex…
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…
Kuhn Losses Regained: Van Vleck from Spectra to Susceptibilities
Charles Midwinter, Michel Janssen
We follow the trajectory of John H. Van Vleck from his 1926 Bulletin for the National Research Council (NRC) on the old quantum theory to his 1932 book, The Theory of Electric and…
