After exploring the interpretation of the experiments, the present paper shows that they were a relevant part of the background to such celebrated contributions to quantum mechanics as Born's statistical interpretation of...

...OLIVAL FREIRE, JR. ABSTRACT In the early 1950s the American physicist David Bohm (1917-1992) produced a new interpretation of quantum mechanics and had to flee from McCarthyism. Rejected at Princeton, he moved to Sãão Paulo. This article focuses on the reception of his early papers on the causal...

A long-term history of the model’s transmission from the 1870s to the 1920s illuminates the ways in which the continuity of knowledge is possible...

...Anja Skaar Jacobsen The Belgian physicist Lééon Rosenfeld (1904––1974) has been called "the clarifier" of Niels Bohr's ideas in quantum mechanics. He had a unique connection to Bohr as his close collaborator from 1930 until Bohr died in 1962. However, although he is considered Bohr's spokesman, he...
