3 days ago · Portrait of Paul Dirac by Clara Ewald (1939) Paul Adrien Maurice Dirac OM FRS (/ d ɪ ˈ r æ k /; 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. He is credited with laying the foundations of quantum ...
4 days ago · The delta function was introduced by physicist Paul Dirac, and has since been applied routinely in physics and engineering to model point masses and instantaneous impulses.
2 hours ago · Across the Channel, the young Cambridge University researcher Paul Adrien Maurice Dirac (Bristol, 1902–Tallahassee, 1984) had developed an independent formalization of quantum mechanics based on the non-commutative algebra of operators, sending his own paper Footnote 1 The Fundamental Equations of Quantum Mechanics to the Proceedings of The Royal Society nine days before the work of the ...
1 day ago · Paul Dirac, 1933 Building on the work of Heisenberg and others, Paul Dirac 's theory of emission and absorption (1927) [54] was the first application of the quantum theory of radiation. Dirac's work was seen as crucially important to the emerging field of quantum mechanics; it dealt directly with the process in which "particles" are actually created: spontaneous emission . [55]
3 days ago · Paul Dirac, in 1945, enshrined the name of Bose by coining the phrase “Boson” to refer to a particle of integer spin, just as he coined “Fermion” after Enrico Fermi to refer to a particle of half-integer spin.
4 days ago · This very fundamental theory caused a true revolution at the beginning of the twentieth century and would represent a fundamental breakthrough for the understanding of materials. However, its application to molecules and materials took a long time due to the enormous complexity of the problem. Paul Dirac put it as follows in 1929:
