This system would come to be known as quantum mechanics. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons. This new generation of quantum theorists was not content with the old quantum theory, developed by the likes of Einstein, Bohr and de Broglie. Credit: Emilio Segre Visual Archives/AIP/SPL After 1925 Einstein’s contributed mainly to the foundations of Quantum Mechanics. In 1930, Einstein argued that quantum mechanics as a whole was inadequate as a final theory of the cosmos. But an inner voice tells me that this is not yet the right track. They were intent on building a more comprehensive and more mathematically robust system. The EPR paper is the best-known expression of Einstein's argument against the completeness of quantum theory. The logic of the paper is a little more tangled than the sketch just given. Einstein’s Unfinished Revolution: The Search for What Lies Beyond the Quantum Lee Smolin Penguin Press (2019). Quantum mechanics is perhaps the most successful theory ever formulated. The theory says a lot, but does not really bring us any closer to the secret of the 'old one'. Not only did Einstein understand quantum mechanics before anybody else, but eminent physicists and science historians such as Leonard Susskind, Douglas Stone, Abraham Pais, T.S. I, at … A biographical history of quantum theory By Howard Jones This is a biographical history of the development of quantum mechanics. But an inner voice tells me that it is not yet the real thing. There is clear evidence that Einstein felt the tangles unnecessary, attributing them to his co-author. “Einstein said that if quantum mechanics were correct then the world would be crazy. B. This system would come to be known as quantum mechanics. Einstein Statistics and his prediction of Bose-Einstein condensation of a boson gas. Particle physics: The first fifty years Let us leave aside the photon for a while and ask how physicists reacted to the experimental discovery or the theoretical prediction (whichever came first) of other new particles. Einstein played a pivotal role in the discovery of Quantum mechanics and this is briefly mentioned. Quantum: Einstein, Bohr and the great debate about the nature of reality, by Manjit Kumar, Icon Books, 2008, 478 ff. After 1925 Einstein’s contributed mainly to the foundations of Quantum Mechanics. Einstein was right - the world is crazy.” ― Daniel M. Greenberger This new generation of quantum theorists was not content with the old quantum theory, developed by the likes of Einstein, Bohr and de Broglie. Einstein is considered the third founder of Quantum Theory because he described light as quanta in his theory of the Photoelectric Effect, for which he won the 1921 Nobel Prize. Discover Albert Einstein quotes about quantum mechanics. In 1926, when quantum mechanics was just a year old, Einstein wrote to his friend Max Born, > Quantum mechanics is very worthy of regard. Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. Niels Bohr (left) with Albert Einstein in the late 1920s, when quantum mechanics was in its infancy. Whereas he was once regarded as too radical in his quantum theories, he now appeared to be too conservative in his defense of classical Newtonian ideas. Letter from A.Einstein to Karl Schwarzschild - Berlin, 9 January 1916 "Quantum mechanics is certainly imposing. All the personalities involved are here it seems. Share with friends.
