		Paul Adrien Maurice Dirac, (August 8, 1902 – October 20, 1984) was a British theoretical physicist and a founder of the field of quantum physics.
		Paul Dirac shared the Nobel Prize for physics in 1933 with Erwin Schrödinger "for the discovery of new productive forms of atomic theory." Dirac was Lucasian professor of mathematics at Cambridge from 1932 to 1969.
		He called the equation for the time-evolution of a quantum-mechanical operator, which Dirac was in fact the first to write down, the 'Heisenberg equation of motion.' Most physicists speak of Fermi-Dirac statistics for half-integer spin particles and Bose-Einstein statistics for integer spin particles.

		In his first publication, in November 1925, Dirac elaborated a method for deriving the equation of motion from quantum mechanics, and a few months later he clearly defined a number of concepts that were to play a major role in the field.
		Dirac's fame stems from his formulation in 1928 of a mathematical description of elementary particles that accords with both quantum mechanics and the theory of relativity.
		Dirac was Lucasian Professor of Mathematics at Cambridge from 1932 to 1969 and professor of physics at Florida State University, from 1971 until his death.

	Featured Physicists - Paul Dirac 1902-1984
		Paul Adrien Maurice Dirac was born in Bristol, England, in 1902.
		Dirac's first degree, obtained at the Merchant Venturer's Technical College, was in electrical engineering, but he had no real interest in the subject and after graduating spent two years studying mathematics at the University of Bristol.
		During this period Dirac worked on a variety of topics including magnetic monopoles (hypothetical magnetic charges) and the speculation that the fundamental constants of physics might be gradually changing in a co-ordinated way.

	Paul Dirac: the purest soul in physics (February 1998) - Physics World - PhysicsWeb
		Paul Dirac was born at 15 Monk Road in Bishopston, Bristol, on 8 August 1902, and educated at the nearby Bishop Road Primary School.
		In Dirac's equation, spin did not have to be imported: it emerged - along with the magnetism of the electron - as an inevitable property of an electron that was both a quantum particle and a relativistic one.
		Dirac also showed how quantum waves for many electrons had to be constructed, incorporating the philosophically intriguing fact that any two of these particles are absolutely identical and so cannot be distinguished in any way.

	CERN Courier - Paul Dirac: a genius in the - IOP Publishing - article
		Paul Dirac died, aged 82, on 20 October 1984 as a Nobel Prize winner (1933) and a member of the British Order of Merit (1973).
		With it, he was able to develop his transformation theory, which showed explicitly (see P Dirac 1927 in Further reading) how it was possible to relate a range of different formulations of quantum mechanics, all of them equivalent in their physical consequences, such as Schrödinger's wave equation and Heisenberg's matrix mechanics.
		In 1927 Dirac sought to develop a theory of the electron that satisfied this requirement and he published his relativistically invariant equation for the electron early in 1928 (see P Dirac 1928 in Further reading).

	Paul Adrien Maurice Dirac
		Dirac's study of theoretical physics began only after he had received a degree in electrical engineering, had failed to find work in this field, and, aided by a grant, had entered St. John's College, Cambridge.
		Dirac's version of quantum mechanics was distinguished, however, by its generality and logical simplicity.
		In a later paper, however, Dirac suggested that a deficiency of an electron in one of these states would be equivalent to a short-lived positively charged particle.

		Paul was one of three children, his older brother being Reginald Charles Felix Dirac and his younger sister being Beatrice Isabelle Marguerite Walla Dirac.
		Dirac had been hoping to have his research supervised by Ebenezer Cunningham, for by this time Dirac had become fascinated in the general theory of relativity and wanted to undertake research on this topic.
		Dirac was appointed Lucasian professor of mathematics at the University of Cambridge in 1932, a post he held for 37 years.

		With the object of formulating atomic laws in the most elegant mathematical language, Dirac applied to quantum mechanics the ideas of Einstein's special theory of relativity.
		In his book The Principles of Quantum Mechanics (4th ed., 1958), Dirac developed the so-called transformation theory of quantum mechanics that furnished a machinery for calculating the statistical distribution of certain variables when others are specified.
		Dirac taught at Cambridge after receiving his doctorate there, and in 1932 he was appointed Lucasian Professor of Mathematics, the chair once held by Isaac Newton.

	Dirac, Paul Adrien Maurice (1902-1984)
		Dirac's electron equation also made the remarkable prediction that there exists a previously unseen type of matter — a particle like the electron, but with opposite charge.
		This was remarkable at the time because only two subatomic particles, the electron and the proton, were known, and there was no suspicion that others might be waiting in the wings.
		When a journalist once asked him to explain the concept of mathematical beauty, Dirac asked the journalist "Do you know mathematics?," and when the journalist replied "No," Dirac said, "Then you can't understand the concept of mathematical beauty." A shy, retiring person, Dirac is not as famous as his achievements warrant.

		Dirac was born and educated in Bristol and from 1923 at Cambridge, where he was professor of mathematics 1932-69.
		The model was able to describe many quantitative aspects of the electron, including such properties as the half-quantum spin and magnetic moment, and introduced the first antiparticle.
		Dirac noticed that those particles with half-integral spins obeyed statistical rules different from the other particles.
