Abstract
We analyze the collaboration between Bohr and Ehrenfest on the quantum theory in the
early 1920s (1920–1923). We focus on their reflections and developments around the
adiabatic principle and the correspondence principle, the two pillars of Bohr’s quantum
theory of 1922–23. We argue that the evolution of Bohr’s ideas after 1918 brought the two
principles closer, subordinating the former to the latter. The examination of the weight
Bohr attributed to each principle along the years illustrates very clearly the
vicissitudes of Bohr’s theory before the emergence of quantum mechanics, especially with
regards to its rejection/inclusion of mechanics.
期刊介绍：
The purpose of this journal is to catalyse, foster, and disseminate an awareness and understanding of the historical development of ideas in contemporary physics, and more generally, ideas about how Nature works.
The scope explicitly includes:
- Contributions addressing the history of physics and of physical ideas and concepts, the interplay of physics and mathematics as well as the natural sciences, and the history and philosophy of sciences, together with discussions of experimental ideas and designs - inasmuch as they clearly relate, and preferably add, to the understanding of modern physics.
- Annotated and/or contextual translations of relevant foreign-language texts.
- Careful characterisations of old and/or abandoned ideas including past mistakes and false leads, thereby helping working physicists to assess how compelling contemporary ideas may turn out to be in future, i.e. with hindsight.
