1. Paul A. M. Dirac - Biography Paul Dirac 1902 a 1984 kvantová elektrodynamika Úvod http://www.nobel.se/physics/laureates/1933/dirac-bio.html

Paul Adrien Maurice Dirac was born on 8th August, 1902, at Bristol, England, his father being Swiss and his mother English. 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

Charles Dirac was a Swiss citizen born in Monthey, Valais 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.

Paul Adrien Maurice Dirac August 8 October 20 ) was a physicist and a founder of the field of quantum physics He was born in Bristol Gloucestershire England In 1926 he developed a version of quantum mechanics, which included “Matrix Mechanics” and “Wave Mechanics” as special cases. In 1928, building on Pauli's work on nonrelativistic spin systems, he derived the Dirac equation , a relativistic equation describing the electron. This allowed Dirac to predict the existence of the positron , the electron's anti-particle; the positron was subsequently observed by Anderson in 1932. Dirac explained the origin of quantum spin as a relativistic phenomenon.

Paul Dirac The English physicist who predicted the existence of the "anti-particle" Paul Dirac (1902-1984), an English physicist, produced useful equations to explain the mysterious magnetic and "spin" qualities of the electron. Dirac's contribution to physics was honored with a Nobel Prize in 1933. Dirac rose to world fame with his prediction that the positron existed Dirac studied electrical engineering and mathematics at Bristol University, then moved to Cambridge University in 1923 to study projective geometry, which took him to such hallowed halls in the field of theoretical physics as the Copenhagen Research Laboratory and Gettingen University. There he met such renowned quantum physicist as Niels Bohr and Werner Heisenberg. Dirac became at teacher at Cambridge in 1927. While there, he produced an equation that combined the theories of quantum mechanics and special relativity and allowed him to successfully forecast the existence of the positron, or an electron that contains a positive charge. Dirac produced numerous equations that helped in the development of quantum mechanics By 1933, the existence of the positron had been confirmed and Dirac was awarded a Nobel Prize in Physics. In 1939 he was awarded with a Royal Medal. He was also presented with the Oppenheimer Award in 1969. Two years later, he moved to Florida State University in the United States. Dirac contributed numerous, vital equations to the field of quantum mechanics. His studies in special relativity, quantum mechanics and wave mechanics and combinations of various theories make him one of the most prominent physicists of the 20th Century.

Paul Dirac The English physicist Paul Adrien Maurice Dirac, b. Aug. 8, 1902, d. Oct. 22, 1984, made significant contributions to the development of quantum mechanics. In September 1925 he read an account of a lecture on quantum mechanics by the German physicist Werner Heisenberg, and quickly devised a number of new mathematical formulations of quantum mechanics that have since proved to be of great importance. 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 was Lucasian Professor of Mathematics at Cambridge from 1932 to 1969 and professor of physics at Florida State University, from 1971 until his death. In 1933 he was awarded the Nobel Prize for physics with Erwin Schrodinger.

Paul A. M. Dirac Professor Dirac's pioneer work in the quantum mechanics of the atom won him the Nobel prize in 1933 at the age of 31. A giant in his field, Dirac has continued to make major contributions in many areas of modern theoretical physics. He is best known for the famous "Dirac equation," with which he reconciled Schroedinger's earlier quantum theory and Einstein's theory of relativity. With his quantum theory of the electron, Dirac replaced Schroedinger's wave equation with more general equations. As the equations are solved, various properties of the electron, such as its spin and magnetic moment, appear. The properties of the solutions to the equations mystified scientists for some time, until Dirac suggested that negative energy states might correspond to the existence of a positive electron or "anti-electron." The subsequent discovery of such anti-electrons and other anti-particles has led to current speculations that there may exist whole worlds of anti- matter in our universe yet to be discovered. Thus Dirac's work is one of the essential foundations of later developments in particle physics. A native of Bristol, England, Dirac received his Ph.D. at Cambridge in 1926. At the age of 30 he was appointed to Cambridge's most prestigious chair, the Lucasian Professorship, which was formerly held by Sir Isaac Newton. He has received countless honors from nations throughout the world. To name a few, he is a Fellow of the Royal Society and was awarded the Society's Royal Medal in 1939. He won the Copley Medal in 1952, was elected to the Pontifical Academy of Sciences in 1961 and in 1973 the Queen of England bestowed upon him the Order of Merit, a special distinction for eminent men and women. He is also a member of the national academies in the U.S., U.S.S.R., and Hungary.

Födelseland: England Födelseår: 1902 Död år: 1984 Paul Adrien Maurice Dirac föddes den 8 augusti år 1902 i England av en schweizisk far och en engelsk mor och skulle komma att bli en av 1900-talets största teoretiska fysiker . Han var mycket blyg och enligt Subrahmanyan Chandrasekhar var han den näst intill perfekta människan; endast hans ovetskap om detta gjorde honom operfekt. Dirac studerade elektroteknik vid universitetet i Bristol och matematik i Cambridge . Snart upptäcktes hans enastående talanger som teoretisk fysiker. År 1926 kombinerade han Max Borns , Pascal Jordans och Werner Heisenbergs matrismekanik med Erwin Schrödingers vågmekanik till en enda kvantmekanisk teori . År 1928 tog han fram den relativistiska formen av teorin (en viktig bekräftelse av den speciella relativitetsteorin) genom att beskriva elektronens egenskaper och kunde därmed förklara begreppet elektronspinn, något som Schrödingers vågmekanik hade misslyckats med (Uhlenbeck och Gouldsmit hade upptäckt elektronspinnet år 1925). Ur den relativistiska teorin så slog han år 1930 fast att lösningar existerar där elektronen har negativ energi existerar. Denna partikel kallade han för positronen och antimaterien var upptäckt (Carl Anderson bekräftade positronens existens experimentellt år 1932). I och med publicerandet av det numera klassiska verket

Paul Adrien Maurice Dirac (8. srpna 1902 – 20. øíjna 1984) Nobelovu cenu získal v roce 1933 spoleènì s E. Schrödingerem za zavedení vlnových rovnic v kvantové mechanice. Anglický fyzik Paul Adrien Maurice Dirac se narodil roku 1902. Studoval elektrotechniku na univerzitì v Bristolu a od roku 1923 matematiku na univerzitì v Cambridgi, kde v roce 1926 získal doktorát. Pøednášel na rùzných svìtových univerzitách. Dirac byl jedním z tvùrcù kvantové mechaniky, kvantové elektrodynamiky a kvantové teorie pole. Po roce 1925, kdy Heisenberg pøišel se svou kvantovou mechanikou, publikoval Dirac celou øadu èlánkù a studií, které se týkaly aplikace Heisenbergovy teorie. Vypracoval základy kvantové teorie záøení a metodu druhého kvantování, která pomohla rozvoji kvantové elektrodynamiky. Dirac vybudoval zákony nové kvantové statistiky, které popisují chování volných elektronù v kovech a které pomohly vysvìtlit fakt, že volné elektrony nepøispívají k mìrnému teplu kovu. Roku 1928 Dirac sjednotil relativistickou teorii pohybu elektronu a kvantovou mechaniku, èímž vytvoøil základy nové teorie o elektronech, a jeho matematické závìry se staly základem pøedstav o magnetickém momentu a spinu elektronu. Nejvìtší Diracùv objev byl vypracován ryze teoretickou cestou a Dirac v nìm pøedpovìdìl existenci nové èástice s hmotností elektronu, ale s kladným nábojem (její existenci experimentálnì potvrdil Anderson v roce 1932 objevem pozitronu v kosmickém záøení).
