What did Paul Dirac discover and why is he important?
Paul Dirac formulated the Dirac equation in 1928, which unified special relativity and quantum mechanics and predicted the existence of antimatter. He also laid the foundations for quantum field theory and quantum electrodynamics, coined those terms, and wrote The Principles of Quantum Mechanics (1930), a landmark textbook still used today. Abdus Salam declared in 1987 that no physicist except Einstein had such a decisive influence on physics in so short a time.
What Nobel Prize did Paul Dirac win and for what work?
Dirac shared the 1933 Nobel Prize in Physics with Erwin Schrodinger, awarded by the Royal Swedish Academy of Sciences "for the discovery of new productive forms of atomic theory." The prize recognised his contributions to quantum mechanics, including the Dirac equation and his development of the mathematical formalism that underlies the field.
What is the Dirac equation and what did it predict?
The Dirac equation, proposed in 1928, is a relativistic equation of motion for the wave function of the electron. Its solutions implied that every fermion must have an antiparticle of equal mass and opposite charge; for the electron, that antiparticle is the positron. Carl Anderson observed the positron experimentally in 1932, confirming the prediction.
Where did Paul Dirac work and teach during his career?
Dirac was Lucasian Professor of Mathematics at the University of Cambridge from 1932 to 1969. After mandatory retirement at age sixty-seven, he joined the University of Miami's Center for Theoretical Studies, then accepted a visiting professorship at Florida State University in September 1970, becoming a full professor there in 1972 and remaining until his death in 1984.
What was Paul Dirac's philosophy of physics?
Dirac believed that physical laws should have mathematical beauty, a principle he wrote on a blackboard at Moscow State University in 1956 that has never been erased. He treated mathematical beauty as both a quality of nature and a practical guide for choosing between competing theories, arguing in a 1939 lecture that the elegance of general relativity was itself a reason to accept it.
Who were Paul Dirac's notable students?
Dirac's students included Homi J. Bhabha, Fred Hoyle, John Polkinghorne, and Freeman Dyson. Subrahmanyan Chandrasekhar attended Dirac's course on quantum mechanics four times in 1930, describing the lectures as "just like a piece of music you want to hear over and over again."
