FICHA Nacionalidad: Reino Unido bristol 8-8-1902 - 1984 Cursó estudios de ingeniería eléctrica en Bristol y más tarde ingresó en Cambridge, donde se licenció en Matemáticas. Al concluir sus estudios, fijó su residencia en América, donde se dedicó a impartir clases. Tras realizar lejanos viajes y llegar hasta Japón y Siberia, regresa a Cambridge. Allí ganó la cátedra lucasiana de matemáticas. Tras permanecer casi cuarenta años en este puesto se trasladó a la Universidad del Estado de Florida para impartir clases de Física. El resultado de sus trabajos fue fundamental para el desarrollo de la mecánica cuántica . Describió las propiedades del electrón y formuló la existencia de una partícula como el electrón, pero con carga positiva. Esta teoría fue confirmada por Carl Anderson, que en 1932 descubrió el positrón. En 1933 fue galardonado con el Premio Nobel de Física, mención que compartió con Erwin Schrödinger. Es autor de obras como "Principios de mecánica cuántica" (1930).

He studied electrical engineering at the University of Bristol before doing research in mathematics at St John's College Cambridge. His first major contribution to quantum theory was a paper written in 1925. He published The principles of Quantum Mechanics in 1930 and for this work he was awarded the Nobel Prize for Physics in 1933. Dirac was appointed Lucasian professor of mathematics at the University of Cambridge in 1932, a post he held for 37 years. He was made a fellow of the Royal Society in 1930, was awarded the Royal Society's Royal Medal in 1939 and the Society awarded him the Copley Medal in 1952.

Origin P. A. M. Dirac "Of course the most famous geniuses of theoretical physics in the twentieth century were Niels Bohr, Albert Einstein, and P. A. M. Dirac. They went far beyond conceiving models or explaining some experimental facts. Einstein revolutionized our concepts of space, time and gravity. Bohr created the most important concepts necessary for dealing with atomic reality. Dirac succeeded in unifying relativity theory with quantum mechanics, leading both to the concept of antimatter and to quantum field theory, a consistent way of dealing with the interaction of matter with electromagnetic and other fields." Victor Weisskopf "Physical Laws should have mathematical beauty." This statement was Dirac's response to the question of his philosophy of physics, posed to him in Moscow in 1955. He wrote it on a blackboard that is still preserved today. [1] Paul Adrien Maurice Dirac (1902-1984), known as P. A. M. Dirac, was the fifteenth Lucasian Professor of Mathematics at Cambridge. He shared the Nobel Prize for Physics in 1933 with Erwin Schrodinger. [2] He is considered to be the founder of quantum mechanics, providing the transition from quantum theory. The Cambridge Philosophical Society awarded him the Hopkins Medal in 1930. He was awarded the Royal Medal by the Royal Society of London in 1939 and the James Scott Prize from the Royal Society of Edinburgh. In 1952 the Max Plank Medal came from the Association of German Physical Societies, as well as the Copley Medal from the Royal Society. The Akademie der Wissenschaften in the German Democratic Republic presented him with the Helmholtz Medal in 1964. In 1969 he received the Oppenheimer Prize from the University of Miami. Lastly in 1973, he received the Order of Merit. [3]

Dirac, Paul Adrien Maurice Anglický fyzik, jeden z hlavních tvùrcù kvantové teorie 20. století. Položil základy kvantové elektrodynamiky a kvantové teorie pole. V roce 1928 odvodil slavnou Diracovu rovnici - relativistickou rovnici pro elektron. Stavy se zápornými energiemi správnì interpretoval jako antièástice a pøedpovìdìl existenci pozitronu (antielektronu). Pozitron byl nezávisle objeven Carlem Andersonem v roce 1932. Za jeho práci na antièásticích a kvantové teorii pole byl v roce 1933 odmìnìn Nobelovou cenou za fyziku. V pozdìjších letech se zabýval dùsledky, které by plynuly z hypotetické promìnnosti základních konstant (gravitaèní, rychlost svìtla a Planckova konstanta). Po celý život byl zastáncem principu jednoduchosti fyzikálních rovnic. Jako jeden z prvních si uvìdomil, že symetrie v pøírodì jsou primárním principem pøi sestavování správných fyzikálních rovnic. P. A. M. Dirac se narodil 8.8.1902 v Anglii v Bristolu. (matka Anglièanka, otec Švýcar). Zaèal studovat Vysokou školu technickou v Bristolu.

Paul Adrien Maurice Dirac Nacido el 08 de agosto de 1902 , en Monk Road in Bishopston, Bristol, Gloucestershire, Inglaterra. Fallecido el 20 de octubre de 1984 , en Tallahassee, Florida, USA. Paul Adrien Maurice Dirac , fue uno de los físicos más influyentes del siglo XX. Muchas de sus contribuciones fueron cruciales para el desarrollo de la mecánica cuántica, la teoría que describe la naturaleza a escalas muy pequeñas. Compartió el premio Nobel de física de 1933 Nobel por sus aportes a la teoría atómica. Dirac nació el 8 de agosto de 1902, en Monk Road en Bishopston, Bristol, Inglaterra. Su padre era suizo y enseñaba francés en la universidad técnica mercantil Venturers en Bristol. Su madre era de Cornwall. Cursó sus estudios primarios en la escuela Bishop Road y los secundarios, primero, en la Merchant Venturers y, más tarde, en Cotham Grammar School. En 1918, entró a la universidad de Bristol, donde se graduó, en 1921, de ingeniero eléctrico con honores de primera clase. Atraído por las teorías de la relatividad de Einstein, pero impedido de tomar una beca en la universidad de Cambridge por razones financieras, permaneció en Bristol y se graduó en matemáticas, otra vez con honores de primera clase, en 1923. Obtenido ese último grado académico, Dirac se fue al St John's College, Cambridge, para realizar investigaciones sobre física teórica bajo supervisión de Ralph (RH) Fowler del laboratorio Cavendish. Después de algunos años de intensa labor investigativa en ese establecimiento, Dirac finalizó el trabajo que le permitió obtener el premio Nobel. En 1932, lo designaron profesor de la cátedra de matemáticas Lucasian en Cambridge, puesto que fue ocupado en su época por Isaac Newton y hoy por Stephen Hawking.

Our greatest endeavour in basic science over the past century has, undoubtedly, been the study of the electromagnetic, strong and weak forces. Although the general theory of relativity was formulated more than 80 years ago, gravitational forces are only now entering the arena of basic scientific research. This is happening because the greatest synthesis of all time, which describes the basic interactions of all the known elementary particles, has finally been achieved in the form of the Standard Model of particle physics. This synthesis is the result of the work of physicists the world over, who have dedicated themselves to the study of what happens when the stable building-blocks of matter (protons, electrons and nuclei) are made to interact at higher and higher energies. The laboratories where physicists have experimentally tested the Standard Model are found around the world, and include famous European names such as CERN in Geneva, the DESY lab near Hamburg, and the Gran Sasso and Frascati labs in Italy. Physicists at Fermilab, Brookhaven and Stanford in the US have also made huge contributions, as have scientists at labs in China, the former Soviet Union and Japan.

The Dirac equation, derived in those papers, is one of the most important equations in physics. Genius at work Each day, I walk past the road where Paul Adrien Maurice Dirac lived as a child. It is pleasant to have even this tenuous association with one of the greatest intellects of the 20th century. Paul Dirac was born at 15 Monk Road in Bishopston, Bristol, on 8 August 1902, and educated at the nearby Bishop Road Primary School. The family later moved to Cotham Road, near the University of Bristol, and in 1914 the young Dirac joined Cotham Grammar School, formerly the Merchant Venturers. Dirac was a student at Bristol University between 1918 and 1923, first in electrical engineering and then in applied mathematics. Much later, he said: "I owe a lot to my engineering training because it [taught] me to tolerate approximations. Previously to that I thought...one should just concentrate on exact equations all the time. Then I got the idea that in the actual world all our equations are only approximate. We must just tend to greater and greater accuracy. In spite of the equations being approximate, they can be beautiful."

Centenário do nascimento de Paul Adrien Maurice Dirac Nascido a 8 de Agosto de 1902 em Bristol, Gloucestershire, Inglaterra Falecido am 20 Outubro de 1984 em Tallahassee, Florida, USA 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, 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.

Centenário do nascimento de Paul Adrien Maurice Dirac Nascido a 8 de Agosto de 1902 em Bristol, Gloucestershire, Inglaterra Falecido am 20 Outubro de 1984 em Tallahassee, Florida, USA Paul Dirac teve dois irmãos, sendo Paul o do meio. O ambiente familiar era bastante estricto devido à severidade de seu pai, Charles Adrien Ladislas Dirac. A primeira escola que frequentou, foi a Escola Primária de Bishop onde começou a demonstrar a sua grande aptidão para a matemática. Aos 12 anos, entrou para a escola secundária onde seu pai lecionava, e que fazia parte do Merchant Venturers Technical College. Por esta altura começou a 1ª Guerra Mundial, que veio trazer algumas "vantagens" para Dirac. Uma vez que os rapazes mais velhos tinham que se alistar no exército, os laboratórios e outras instalações passaram a estar mais disponíveis. O próprio Dirac, aos treze anos, escreveu: "The Merchant Venturers was an excellent school for science and modern languages. There was no Latin or Greek, something of which I was rather glad, because I did not appreciate the value of old cultures. I consider myself very lucky in having been able to attend the school. ... I was rushed through the lower forms, and was introduced at an especially early age to the basis of mathematics, physics and chemistry in the higher forms. In mathematics I was studying from books which mostly were ahead of the rest of the class. This rapid advancement was a great help to me in my latter career."

Paul Adrian Maurice Dirac The following interview with Paul Dirac was conducted by David Peat ( DP ) and Paul Buckley ( PB ) in the early 1970's for broadcast as part of a CBC radio documentary series entitled Physics and Beyond . The interview was later published in Glimpsing Reality: Ideas in Physics and the Link to Biology , a collection of interviews with leading scientists of the Twentieth Century. The book is available for purchase through Amazon.com To take a one week course with David Peat In one of C.P. Snow's early novels a character in the scientific life of Cambridge is described as the successor of Newton. It can only be Paul Dirac (1902-). Like Newton before him Dirac has made contributions that are respected by his colleagues not only for their depth of insight and clarity but for the power and economy with which mathematics is brought to bear upon the problems of nature. Dirac`s scientific papers have the polished and balanced appearance of a sculpture by Brancusi. While Heisenberg was discovering the principles of quantum mechanics in his Helgoland retreat, Erwin Schrödinger followed a different path to derive his wave mechanics of the atom. Dirac was able to show that the two theories were equivalent, and in the process provided quantum theory with a sound mathematical footing. His contributions in physics also include the quantum theory of matter and radiation, the prediction of the spin of the electron, and the existence of the positron as well as an attempt to form a marriage between quantum theory and the theory of relativity. He was awarded the Nobel Prize in 1933.
