Vor 3 Tagen · These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect ) in convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism.
Vor 2 Tagen · In 1912 Einstein praised Paul Ehrenfest as “one of the few theorists who has not been robbed of his natural mind by the mathematical epidemic!” And when Max Abraham made an early attempt at developing a relativistic theory of gravity, Einstein immediately pounced on the idea that Abraham had allowed himself to be bamboozled by mathematical elegance. In a letter to Michele Besso he writes
Vor 2 Tagen · In the autumn of 1928, Oppenheimer visited Paul Ehrenfest's institute at the University of Leiden, the Netherlands, where he impressed by giving lectures in Dutch, despite having little experience with the language.
Vor 6 Tagen · Then I learned from a friend that there was a field called mathematical economics, and that Jan Tinbergen, a former student of Paul Ehrenfest, had left physics to devote himself to economics. Tinbergen received me cordially and guided me into the field in his own inimitable way. I moved to Amsterdam, which had a faculty of economics. The transition was not easy. I found that I benefited more ...
Vor 3 Tagen · Special relativity. Paul Adrien Maurice Dirac OM FRS [6] ( / dɪˈræk /; 8 August 1902 – 20 October 1984) was an English mathematical and theoretical physicist who is considered to be one of the founders of quantum mechanics and quantum electrodynamics. [7] [8] He is credited with laying the foundations of quantum field theory.
Vor 5 Tagen · In a 1926 letter to Paul Ehrenfest, Albert Einstein wrote of Dirac, "This balancing on the dizzying path between genius and madness is awful." Dirac openly criticized the political purpose of religion. He said: "I cannot understand why we idle discussing religion. If we are honest---and scientists have to be---we must admit that ...
