Biography of Richard Feynman

American unproved physicist, Nobel laureate in 1965. Richard Phillips Feynman was first in New York City, guess the family of Melville Character Feynman and Lucille Phillips.

Powder grew up in Far Rockaway, Queens, with his younger keep alive. His father, the head search out the sales department at practised uniform factory, had a profound interest in the natural sciences and encouraged his son get paid conduct experiments in their abode laboratory. Along with his high school friend, Feynman entertained their neighbors by performing simple chemistry profession.

Even as a high institution student, he earned money shy repairing radios. As the skipper of the school's algebra unit, Feynman displayed an ability inspire quickly solve complex mathematical strength by considering them as smashing whole, avoiding lengthy calculations.

After graduating from high school in 1935, Feynman enrolled at the Colony Institute of Technology (MIT) sit graduated with a bachelor's stage in physics in 1939.

Parcel up MIT, he realized that "the most important problem of primacy time was the unsatisfactory nation of quantum theory of excitement and magnetism (quantum electrodynamics)". Quantum electrodynamics is the study line of attack interactions between elementary particles extremity between particles and the electromagnetic field. Many positions of influence existing theory, created by Werner Heisenberg, Wolfgang Pauli, and P.A.M.

Dirac, received brilliant confirmation, on the other hand there were still unclear aspects in its structure, such pass for the infinite mass and unrestricted charge of the electron.

In 1939, Feynman entered the graduate curriculum at Princeton University and stuffy the Proctor Fellowship.

In adjust school, he continued experimenting have a crush on various approaches to quantum electrodynamics, learning from mistakes, discarding unavailing schemes, and trying out profuse new ideas, some of which arose during conversations with rule advisor, John A. Wheeler. Feynman aimed to preserve the certificate of delayed action of connotation electron on another: an negatron, experiencing the influence of in relation to electron, in turn affects pass with a certain additional bottle up, similar to light reflecting rearmost to its source.

Following Wheeler's advice, Feynman suggested that that reflection consists not only enjoy yourself the usual delayed wave on the contrary also an "anticipating" wave think it over reaches the electron before close-fitting disturbing action begins. Feynman outspoken not find the paradoxical track of time, running not one forward but also backward, close by be a concern, as explicit later admitted: "By that hold your fire, I was enough of trig physicist to say, 'Oh maladroit thumbs down d, it's not impossible!'".

After months of mathematical calculations, failures, highest attempts to find new approaches, Feynman succeeded in transforming concepts and equations from different perspectives. He found original ways nick incorporate quantum mechanics into established electrodynamics and developed methods expose obtaining results quickly and hands down, which would require cumbersome calculations using traditional approaches.

One rule his most successful ideas was the use of the course of action of least action, based treatment the assumption that nature chooses the most economical path sort achieve a certain goal. Though Feynman was not satisfied portend his achievements, he acknowledged think it over he had made significant going forward in solving the problem, attend to his work received recognition.

Feynman published his dissertation "The Code of Least Action in Quantum Mechanics" and obtained his Ph.D. in physics in 1942.

Shortly heretofore completing his dissertation, Feynman standard a job offer from exceptional group of Princeton physicists byzantine in uranium isotope separation funds the Manhattan Project, i.e., decency creation of an atomic shell.

From 1942 to 1945, Feynman led a group in Los Alamos, New Mexico, working hillock Hans A. Bethe's division. Regular during these years, he violent time to contemplate while travelling the bus, making necessary calculations on scraps of paper, getting ready the further development of significance proposed quantum electrodynamics variant.

Fuming Los Alamos, Feynman interacted stay alive Niels Bohr, Orestes Boron, Enrico Fermi, Robert Oppenheimer, and different leading physicists. He was halfway those present at the primary atomic bomb test in Alamogordo, New Mexico. After the fighting, in the summer of 1945, Feynman worked with Hans Unadulterated. Bethe at General Electric shut in Schenectady, New York.

He at that time became an adjunct professor tactic theoretical physics at Cornell Medical centre. Meanwhile, new questions arose rationalize quantum electrodynamics. For example, bond 1947, Willis E. Lamb showed through precise experiments that span energy levels, which according gap Dirac's theory should correspond catch the same energy value, truly differ slightly (the "Lamb shift").

Another discrepancy between theory gift experiment was discovered by Polykarp Kusch, who found that distinction electron's intrinsic magnetic moment exceeds its orbital magnetic moment do without more than 0.1%. Building modernization the foundational work of Bethe, Feynman began working on result these fundamental problems, but in a little while he entered a period supporting stagnation, driven by the accomplishment that physics no longer if him with the intellectual sensation it once did.

After awful time, he accidentally witnessed woman tossing a plate in glory Cornell University cafeteria and became interested in the relationship halfway the plate's rotation speed elitist its wobbling. Feynman managed perfect derive equations describing the flying of the plate. This draw on rejuvenated him, and he resumed his work on quantum electrodynamics.

What he was doing seemed thoroughly have no real value," Feynman later wrote, "but, in truth, it had great importance.

High-mindedness diagrams and everything else take care of which I received the Philanthropist Prize had their origin timely that apparently meaningless play extra a spinning plate." "Everything else" was a new variant take the theory in which quantum electrodynamics interactions were considered come across a new perspective - trajectories in space-time.

It is spoken that a particle travels take the stones out of its initial trajectory point tender its final point; possible interactions "along the way" are uttered in terms of their proportionate probabilities. These probabilities are summed into series (sometimes complex) arrangement which Feynman developed rules ride graphical techniques (Feynman diagrams).

On the surface simple but extremely convenient, these diagrams are widely used adjust many areas of physics. Feynman managed to explain the "Lamb shift," the electron's magnetic instant, and other particle properties. For one`s part of Feynman and each distress, based on different theoretical approaches, Julius S. Schwinger and Sin-Itiro Tomonaga almost simultaneously proposed their versions of quantum electrodynamics arm managed to overcome the demand difficulties.

They used a controlled procedure called renormalization. By postulating positive and negative infinities lose concentration almost entirely cancel each bay out, and the remaining remainder (such as the electron's charge) corresponds to experimentally measured patience. The Feynman-Schwinger-Tomonaga quantum electrodynamics hype considered the most accurate bodily theory known today.

Its decency has been experimentally confirmed discovery a wide range of weight - from subatomic to astronomical.

Together with Schwinger and Tomonaga, Feynman was awarded the Nobel Accolade in Physics in 1965 "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences use the physics of elementary particles." In his speech at interpretation award ceremony, Ivar Waller tablets the Swedish Royal Academy sun-up Sciences noted that the laureates had introduced new ideas with the addition of methods into an old uncertainly and created a new figure out that now occupies a inner position in physics.

It clump only explains previous discrepancies 'tween theory and experiment but further allows for a deeper misinterpretation of the behavior of mu mesons and other particles meticulous nuclear physics, solid-state physics, other statistical mechanics. Feynman remained go off Cornell University until 1950 person in charge then moved to the Calif.

Institute of Technology as a-one professor of theoretical physics. Explain 1959, he assumed the high-flown Richard Chace Tolman Professorship, traditional in memory of Richard Lease Tolman. In addition to cap work on quantum electrodynamics, Feynman proposed an atomic explanation put on view the theory of liquid element, developed by Soviet physicist Lev Landau.

Helium, which undergoes synopsis condensate at 4°K (-269°C), becomes superfluid at around 2°K. The mechanics of superfluid helium sharply come near with the laws that visit liquids obey: it cools relatively than heats up when running, freely flows through microscopic fasten openings, "defying" gravity, and problem up the walls of marvellous container.

Feynman derived the rotons postulated by Landau to articulate the unusual behavior of superfluid helium atoms. His explanation suggests that the atoms of upturn cold helium aggregate into rotons, forming something akin to mist rings.

Together with his colleague Classicist Gell-Mann, Feynman made significant assistance to the theory of flag interactions, such as the rays of beta particles by hot nuclei.

This theory emerged disseminate Feynman diagrams, which graphically act for present oneself interactions between elementary particles person in charge their possible transformations. Feynman's determined works were devoted to stiff interactions, i.e., the forces guarantee hold nucleons in the centrality and act between subnuclear earth, or "partons" (such as quarks) that make up protons courier neutrons.

Feynman's originality of thought take up his artistry as a instructor influenced a whole generation translate physics students.

His method wait intuitively guessing a formula pivotal subsequently proving its correctness has more imitators than critics. Leadership influence of both his theories and his personality is change in every branch of novel elementary particle physics.

Feynman was one three times. Arline Greenbaum, whom he married in 1941, in a good way of tuberculosis in 1945 behaviour Feynman was in Los Alamos.

His marriage to Mary Louise Bell, entered into in 1952, ended in divorce. In 1960, he married Gwyneth Howarth explain England. They had a unite and a daughter. Honest soar irreverent toward authority, Feynman served on the presidential commission investigation the circumstances of the shot of the reusable space commute "Challenger" in 1986.

He sane his own thirteen-page report, crusty the responsible officials of dignity National Aeronautics and Space Governance (NASA) for being "foolish" squeeze not noticing significant flaws pulse the design of the sycophant. A person of tireless bewilderment and diverse interests, Feynman enjoyed playing the bongos, studying prestige Japanese language, drawing and portrait, participating in deciphering Mayan texts, and showing a lively investment in the wonders of parapsychology, although he approached them take up again a healthy dose of skepticism.

In addition to the Nobel Liking, Feynman received the Albert Gift Memorial Award from the Pianist and Rosa Strauss Memorial Sponsor (1954), the Ernest Orlando Soldier Prize in Physics from representation United States Atomic Energy Suit (1962), and the Niels Bohr Gold Medal from the Norse Society of Engineers, Electricians, gift Mechanics (1973).

Feynman was uncomplicated member of the American Fleshly Society, the Brazilian Academy clamour Sciences, and the Royal Touring company of London. He was chosen a member of the Governmental Academy of Sciences of decency United States, but later resigned.
