Ecyclopedia Home Paul Dirac Common Misspellings for Paul Dirac Paul Adrien Maurice Dirac August 8 October 20 ) was a British theoretical physicist and a founder of the field of quantum physics Biography 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). Dirac studied electrical engineering at the University of Bristol , completing his degree in 1921. After working briefly as an engineer, Dirac decided that his true calling lay in the mathematical sciences. He completed a degree in

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.

But, a new exhibition by Britain's Royal Society points out, it's because of him that we've got electronics. So who was he? The mathematician Mark Kac divided geniuses into two classes. Ordinary ones whose achievements others will emulate, and magicians whose inventions are so astounding that it is hard to see how any human could have imagined them. Paul Dirac was one of these magicians. When he went to Cambridge in 1923, at the age of 21, the world of physics was in turmoil. Experiments had shown that classical physicists could not explain the behaviour of atoms. The old principles of Isaac Newton didn't seem to apply to the microscopic world. The Dirac equation Dirac soon developed his own widely-acclaimed theory of quantum mechanics. His theory included wave mechanics, the version of quantum mechanics developed by Erwin Schrodinger, and matrix mechanics, the theory put forward by Werner Heisenberg.

Acceleration : the process which consists of giving energy to a particle beam. This is achieved by the radio-frequency (RF) cavities Antiproton The antimatter equivalent of the proton, with the same mass but opposite charge. Atomic energy levels The possible energy of electronic orbitals in an atom are restricted to well-defined and discrete values. They are called the "energy levels of the atom". Their value is measured relative to the energy required to remove an electron, which is called the ionization potential of the atom Beam : a collection of particles traveling in an accelerator, storage ring, or transfer line. Bubble Chamber A detector filled with a liquid close to its boiling point, where the ionizing particles' trajectories materialize in the form of tracks made of bubbles. Cloud Chamber A detector filled with a gas close to its condensation point, where the ionizing particles' trajectories materialize in the form of tracks made of droplets. Cooling By analogy with the kinetic theory of gases where heat is equivalent to disorder, the term "cooling" designates the reduction of the beam's transverse dimensions and energy spread. Different techniques can be used to this effect.

Dirac, Paul Adrien Maurice (1902-1984) Físico teórico británico, premiado con el Nobel , y célebre por su predicción de la existencia del positrón , o electrón positivo, y por sus investigaciones en teoría cuántica Dirac nació en Bristol y estudió en las universidades de Bristol y Cambridge. Su teoría cuántica del movimiento del electrón le llevó en 1928 a formular la existencia de una partícula idéntica al electrón en todos los aspectos excepto en la carga: el electrón con una carga negativa y esta hipotética partícula con una carga positiva. La teoría de Dirac se confirmó en 1932, cuando el físico estadounidense Carl Anderson descubrió el positrón . En 1933 Dirac compartió el Premio Nobel de Física con el austriaco Erwin Schrödinger , y en 1939 fue nombrado miembro de la Sociedad Real. Fue profesor de matemáticas en Cambridge desde 1932 a 1968, profesor de física en la Universidad del estado de Florida desde 1971 hasta su muerte, y miembro del Instituto de Estudios Avanzados, entre 1934 y 1959.

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.

One consequence of his theory was the prediction of negative energy states for the electron, implying the existence of an antiparticle to the electron; this antiparticle, the positron, was discovered in 1932 by C. D. Anderson. Dirac's equation for the motion of a particle is a relativistic modification of the SchrOdinger wave equation, the basic equation of quantum mechanics. For their work Dirac and Erwin SchrOdinger shared the 1933 Nobel Prize in Physics. Dirac also received the Copley Medal of the Royal Society in 1952 for this and other contributions to the quantum theory, including his formulation (with Enrico Fermi) of the Fermi-Dirac statistics and his work on the quantum theory of electromagnetic radiation. He wrote The Principles of Quantum Mechanics (1930, 4th ed. 1958).

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.

Read This! The MAA Online book review column Paul Dirac: the man and his work edited by Peter Goddard Reviewed by Fernando Q. Gouvêa Mathematics and Physics have always had a close relationship, though the level of friendliness between the two disciplines has, of course, varied from time to time. This little book focuses on a physicist who was trained as a mathematician and who brought a very mathematical turn of mind to bear on physical problems in a very fruitful way. As Peter Goddard says in his introduction, "Dirac cited mathematical beauty as the ultimate criterion for selecting the way forward in theoretical physics." This method was sometimes enormously successful, as when Dirac predicted the existence of the positron simply because his mathematics required such particles to exist. This is a feat on the order of the prediction of the existence of Uranus and Neptune on the basis of the gravitational anomalies in the solar system. In both cases, a mathematical theory led physicists to postulate, and then verify, the existence of some objective entity; they both demonstrate the real power of mathematics as a tool to understand the universe. The story isn't all positive, though, as Abraham Pais makes clear in his survey of Dirac's life and work. After his initial successes in the 1930s, Dirac seems to have been far less fortunate in his research. Though he remained an interesting and powerful voice, he seemed seriously distressed by the mathematical difficulties in quantum theory, most particularly in quantum electrodynamics, of which he said "the resulting theory is an ugly and incomplete one." The "renormalization" procedure which is used to deal with the divergent expansions in the theory did not satisfy him at all, and he spent great energy in trying to find the "right" theory. Pais quotes a letter that expresses his final attitude on this subject:
