The Ehrenfest Adiabatic Hypothesis and the Old Quantum Theory, Before Bohr

In 1918, Bohr published the first two parts of On the quantum theory of line spectra. In this extensive contribution, he offered a quantum theory much more elaborated than the one contained in his seminal works of 1913. Besides innovations of his own More The Ehrenfest Adiabatic Hypothesis and the Old Quantum Theory, Before Bohr

“The” Correspondence Principle

Both the textbook tradition and vast segment of the secondary historical literature speaks as though there is such a thing em The Correspondence Principle, which (i) was first articulated explicitly by Bohr (1917) in Part I. of “On the Quantum Theory of Line Spectra,” (QTLS) (ii) More “The” Correspondence Principle

Probing Concepts, Old and New: Einstein's Interpretation of Superconductivity

In 1920, Einstein was appointed visiting professor at the University of Leiden. A major motivation for this appointment was his perception as a leading quantum theorist and the expectation that he would provide theoretical More Probing Concepts, Old and New: Einstein's Interpretation of Superconductivity
