文摘

We analyze the collaboration between Bohr and Ehrenfest on the quantum theory in theearly 1920s (1920–1923). We focus on their reflections and developments around theadiabatic principle and the correspondence principle, the two pillars of Bohr’s quantumtheory of 1922–23. We argue that the evolution of Bohr’s ideas after 1918 brought the twoprinciples closer, subordinating the former to the latter. The examination of the weightBohr attributed to each principle along the years illustrates very clearly thevicissitudes of Bohr’s theory before the emergence of quantum mechanics, especially withregards to its rejection/inclusion of mechanics.
