Extractions: Main Page '''Paul Adrien Maurice Dirac''', ( August 8 October 20 ) was a British theoretical physicist and a founder of the field of quantum physics Paul Dirac was born in the English city of Bristol . His father, Charles Dirac, was an immigrant from the Valais Canton in Switzerland who taught French for a living. His mother was originally from Cornwall and the daughter of a mariner. Paul had an elder brother and an younger sister. His early family life appears to have been unhappy on account of his father's unusually strict and authoritarian nature, but he never publicly expressed his feelings on the subject. He was educated first at Bishop Primary School and later at Merchant Venturers Technical College. The latter was an institution, attached to the University of Bristol , that emphasized scientific subjects and modern languages (an unusual arrangement at a time when secondary education in Britain was still dedicated largely to the classics , and something for which Dirac would later express gratitude).

When one looks back over the development of physics, one sees that it can be pictured as a rather steady development with many small steps and superposed on that a number of big jumps. These big jumps usually consist in overcoming a prejudice...And then a physicist has to replace this prejudice by something more precise, and leading to some entirely new conception of nature. (Paul Dirac, Quantum Theory) This statistical interpretation is now universally accepted as the best possible interpretation for quantum mechanics / quantum theory, even though many people are unhappy with it. People had got used to the determinism of the last century, where the present determines the future completely, and they now have to get used to a different situation in which the present only gives one information of a statistical nature about the future. A good many people find this unpleasant; Einstein has always objected to it. The way he expressed it was: "The good God does not play with dice". Schroedinger also did not like the statistical interpretation and tried for many years to find an interpretation involving determinism for his waves.

He was educated at the Merchant Venturer's Secondary School, Bristol, then went on to Bristol University. Here, he studied electrical engineering, obtaining the B.Sc. (Engineering) degree in 1921. He then studied mathematics for two years at Bristol University, later going on to St.John's College, Cambridge, as a research student in mathematics. He received his Ph.D. degree in 1926. The following year he became a Fellow of St.John's College and, in 1932, Lucasian Professor of Mathematics at Cambridge. Dirac's work has been concerned with the mathematical and theoretical aspects of quantum mechanics. He began work on the new quantum mechanics as soon as it was introduced by Heisenberg in 1928 - independently producing a mathematical equivalent which consisted essentially of a noncommutative algebra for calculating atomic properties - and wrote a series of papers on the subject, published mainly in the Proceedings of the Royal Society, leading up to his relativistic theory of the electron (1928) and the theory of holes (1930). This latter theory required the existence of a positive particle having the same mass and charge as the known (negative) electron. This, the positron was discovered experimentally at a later date (1932) by

Extractions: Version for printing Paul Dirac 's father was Charles Adrien Ladislas Dirac and his mother was Florence Hannah Holten. Charles Dirac was a Swiss citizen born in Monthey, in the Valais Canton of Switzerland, while his mother came from Cornwall in England. Charles had been educated at the University of Geneva, then came to England in around 1888 and taught French in Bristol. There he met Florence, whose father had moved to Bristol as Master Mariner on a Bristol ship, when she was working in the library there. Charles and Florence married in 1899 and they moved into a house in Bishopston, Bristol, which they named Monthey after the town of Charles's birth. By this time Charles was teaching French at the secondary school attached to the Merchant Venturers Technical College in Bristol. Paul was one of three children, his older brother being Reginald Charles Felix Dirac and his younger sister being Beatrice Isabelle Marguerite Walla Dirac. Paul had a very strict family upbringing. His father insisted that only French be spoken at the dinner table and, as a result, Paul was the only one to eat with his father in the dining room. Paul's father was so strict with his sons that both were alienated and Paul was brought up in a somewhat unhappy home.

Extractions: Diracs "Coincidences" Sixty Years On Robert A. J. Matthews Abstract : Sixty years ago, the existence of "coincidences" between dimensionless ratios of sub-atomic and cosmological quantities prompted Dirac to develop a cosmological model based on a suspected connection between physics at the quantum and cosmic levels. While his original proposal has not stood the test of time, recent developments linking cosmology to quantum vacuum processes may yet breathe new life into Diracs intriguing hypothesis. This year marks the 60th anniversary of Paul Diracs paper A new basis for cosmology , outlining a new cosmological model based on the existence of a set of extraordinary "coincidences" in cosmic and atomic physics (Dirac 1938). In his paper, Dirac noted that, for some unexplained reason, the ratio of the electrostatic to gravitational force between an electron and a proton is roughly equal to the age of the universe divided by an elementary time constant, implying that hc/Gm p m e ~ m p c where h is Plancks constant, c the speed of light, G the Newtonian gravitational constant, m e and m p the masses of the electron and proton respectively, and H is the cosmic Hubble parameter. On rearrangement (1) leads to the intriguing implication that the expansion rate of the universe, as measured by H, is linked to sub-atomic quantities via a relationship of the form

Extractions: Paul A. M. Dirac One of the founders of quantum mechanics, known as a man of few words. He contributed greatly to constructing relativistic quantum electrodynamics, combining both Einstein's relativity and quantum mechanics. In this process, he stumbled over the problem of negative energy of an electron which can be derived from his "spin 1/2 Dirac equation". Eventually, this difficulty led him to predict the existence of "positron", the anti-particle of electron (and, every particle has its own anti-particle, and matter and anti-matter form a pair, although we mostly encounter matter in this world). This prediction was experimentally confirmed later (1932). Dirac shared the Nobel physics prize with Schroedinger in 1933. The preceding discovery changed the concept of "vacuum" in physics. It is not a state of emptiness, but a state of quantum fluctuation-an electron may materialize together with a positron out of nothing, and soon annihilate into nothingness again; the inherent probabilistic character of quantum mechanics allows this.
