Julian Seymour Schwinger (February 12, 1918 – July 16, 1994) was an American theoretical physicist. He is best known for his work on the theory of quantum electrodynamics, in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.

Schwinger is recognized as one of the greatest physicists of the twentieth century, responsible for much of modern quantum field theory, including a variational approach, and the equations of motion for quantum fields. He developed the first electroweak model, and the first example of confinement in 1+1 dimensions. He is responsible for the theory of multiple neutrinos, Schwinger terms, and the theory of the spin 3/2 field.

Biography

Schwinger was born in New York City where he attended Townsend Harris High School and then the City College of New York as an undergraduate before transferring to Columbia University, where he received his B.A. in 1936 and his Ph.D. (overseen by I.I. Rabi) in 1939 at the age of 21. He worked at the University of California, Berkeley (under J. Robert Oppenheimer) and was later appointed to a position at Purdue University.

Career

After having worked with Oppenheimer, Schwinger chose to work at the Radiation Laboratory at MIT instead of at the Los Alamos National Laboratory during World War II. He provided theoretical support for the development of radar. After the war, Schwinger left Purdue for Harvard University, where he taught from 1945 to 1974.

Schwinger developed an affinity for Green's functions from his radar work, and he used these methods to formulate quantum field theory in terms of local Green's functions in a relativistically invariant way. This allowed him to calculate unambiguously the first corrections to the electron magnetic moment in quantum electrodynamics. Earlier non-covariant work had arrived at infinite answers, but the extra symmetry in his methods allowed Schwinger to isolate the correct finite corrections. Schwinger developed renormalization, formulating quantum electrodynamics unambiguously to one-loop order.

In the same era, he introduced non-perturbative methods into quantum field theory, by calculating the rate at which electron-positron pairs are created by tunneling in an electric field, a process now known as the "Schwinger effect". This effect could not be seen in any finite order in perturbation theory.

Schwinger's foundational work on quantum field theory constructed the modern framework of field correlation functions and their equations of motion. His approach started with a quantum action and allowed bosons and fermions to be treated equally for the first time, using a differential form of Grassman integration. He gave elegant proofs for the spin-statistics theorem and the CPT theorem, and noted that the field algebra led to anomalous Schwinger terms in various classical identities, because of short distance singularities. These were foundational results in field theory, instrumental for the proper understanding of anomalies.

In other notable early work, Rarita and Schwinger formulated the abstract Pauli and Fierz theory of the spin 3/2 field in a concrete form, as a vector of Dirac spinors. In order for the spin-3/2 field to interact consistently, some form of supersymmetry is required, and Schwinger later regretted that he had not followed up on this work far enough to discover supersymmetry.

Schwinger discovered that neutrinos come in multiple varieties, one for the electron and one for the muon. Nowadays there are known to be three light neutrinos; the third is the partner of the tau lepton.

In the 1960s, Schwinger formulated and analyzed what is now known as the Schwinger model, quantum electrodynamics in one space and one time dimension, the first example of a confining theory. He was also the first to suggest an electroweak gauge theory, an SU(2) gauge group spontaneously broken to electromagnetic U(1) at long distances. This was extended by his student Sheldon Glashow into the accepted pattern of electroweak unification. He attempted to formulate a theory of quantum electrodynamics with point magnetic monopoles, a program which met with limited success because monopoles are strongly interacting when the quantum of charge is small.

Having supervised more than seventy doctoral dissertations, Schwinger is known as one of the most prolific graduate advisors in physics. Four of his students won Nobel prizes: Roy Glauber, Benjamin Roy Mottelson, Sheldon Glashow and Walter Kohn (in chemistry).

Schwinger had a mixed relationship with his colleagues, largely because of his source theory. Schwinger considered source theory as a substitute for field theory, although it is only a different point of view, a version of effective field theory. It treats quantum fields as long-distance phenomena, and does not require a well defined continuum limit. Source theory was considered overly formal and lacking in distinctness from quantum field theory, and the criticisms by his Harvard colleagues led Schwinger to leave the faculty in 1972 for UCLA. It is a story widely told that Steven Weinberg, who inherited Schwinger's paneled office in Lyman Laboratory, there found a pair of old shoes, with the implied message, "think you can fill these?". At UCLA, and for the rest of his career, Schwinger continued to develop source theory reformulations of quantum field theoretic results.

After 1989 Schwinger took a keen interest in the non-mainstream research of low-energy nuclear fusion reactions (AKA cold fusion). He wrote eight theory papers about it. He resigned from the American Physical Society after their refusal to publish his papers. He felt that cold fusion research was being suppressed and academic freedom violated. He wrote: "The pressure for conformity is enormous. I have experienced it in editors’ rejection of submitted papers, based on venomous criticism of anonymous referees. The replacement of impartial reviewing by censorship will be the death of science."

In his last publications, Schwinger proposed a theory of sonoluminescence as a long distance quantum radiative phenomenon associated not with atoms, but with fast-moving surfaces in the collapsing bubble, where there are discontinuities in the dielectric constant. Standard explanations, now supported by experiments, focus on superheated gas atoms inside the bubble as the source of the light , but Schwinger's methods tie back to his old quantum electrodynamic papers.

Schwinger was jointly awarded the Nobel Prize in Physics in 1965 for his work on quantum electrodynamics (QED), along with Richard Feynman and Shinichiro Tomonaga. Schwinger's awards and honors were numerous even before his Nobel win. They include the first Albert Einstein Award (1951), the U.S. National Medal of Science (1964), honorary D.Sc. degrees from Purdue University (1961) and Harvard University (1962), and the Nature of Light Award of the U.S. National Academy of Sciences (1949).

Schwinger and Feynman

As a famous physicist, Schwinger was often compared to another legendary physicist of his generation, Richard Feynman. Schwinger was more formally inclined and favored symbolic manipulations in quantum field theory. He worked with local field operators, and found relations between them, and he felt that physicists should understand the algebra of local fields, no matter how paradoxical.

By contrast, Feynman was more intuitive, believing that the physics could be extracted entirely from the Feynman diagrams, which gave a particle picture. Schwinger commented on Feynman diagrams in the following way,

Schwinger disliked Feynman diagrams because he felt that they made the student focus on the particles and forget about local fields, which in his view inhibited understanding. He went so far as to ban them altogether from his class, although he understood them perfectly well and was observed to use them in private.

Despite sharing the Nobel Prize, Schwinger and Feynman had a different approach to quantum electrodynamics and to quantum field theory in general. Feynman used a regulator, while Schwinger was able to formally renormalize to one loop without an explicit regulator. Schwinger believed in the formalism of local fields, while Feynman had faith in the particle paths. They followed each other's work closely, and each respected the other. On Feynman's death, Schwinger described him as

Murray Gell-Mann (; born September 15, 1929) is an American physicist who received the 1969 Nobel Prize in physics for his work on the theory of elementary particles. He is the Robert Andrews Millikan Professor of Theoretical Physics Emeritus at Caltech, a Distinguished Fellow and co-founder of the Santa Fe Institute, Professor in the Physics and Astronomy Department of the University of New Mexico, and the Presidential Professor of Physics and Medicine at the University of Southern California.

He formulated the quark model of hadronic resonances, and identified the SU(3) flavor symmetry of the light quarks, extending isospin to include strangeness, which he also discovered. He developed the V-A theory of the weak interaction in collaboration with Richard Feynman. He created current algebra in the 1960s as a way of extracting predictions from quark models when the fundamental theory was still murky, which led to model-independent sum rules confirmed by experiment.

Gell-Mann, along with Maurice Lévy, developed the sigma model of pions, which describes low energy pion interactions. Modifying the integer-charged quark model of Han and Nambu, Fritzsch and Gell-Mann were the first to write down the modern accepted theory of quantum chromodynamics, although they did not anticipate asymptotic freedom. In 1969 he received the Nobel Prize in physics for his contributions and discoveries concerning the classification of elementary particles and their interactions.

Gell-Mann is responsible for the see-saw theory of neutrino masses, that produces masses at the inverse-GUT scale in any theory with a right-handed neutrino, like the SO(10) model. He is also known to have played a large role in keeping string theory alive through the 1970s and early 1980s, supporting that line of research at a time when it was unpopular.

Biography

Gell-Mann was born in lower Manhattan into a family of Jewish immigrants from the Austro-Hungarian Empire, Gell-Mann quickly revealed himself as a child prodigy. Propelled by an intense boyhood curiosity and love for nature and mathematics, he graduated valedictorian from the Columbia Grammar & Preparatory School and subsequently entered Yale at the age of 15 as a member of Jonathan Edwards College.

Gell-Mann's work in the 1950s involved recently discovered cosmic ray particles that came to be called kaons and hyperons. Classifying these particles led him to propose that a quantum number called strangeness would be conserved by the strong and the elementary interactions, but not by the weak interactions. Another of Gell-Mann's ideas is the Gell-Mann-Okubo formula, which was, initially, a formula based on empirical results, but was later explained by the quark model. Gell-Mann and Abraham Pais were involved in explaining many puzzling aspects of the physics of these particles.

In 1961, this led him (and Kazuhiko Nishijima) to introduce a classification scheme for hadrons, elementary particles that participate in the strong interaction. (This scheme was independently proposed by Yuval Ne'eman.) This scheme is now explained by the quark model. Gell-Mann referred to the scheme as the ''Eightfold Way'', because of the ''octets'' of particles in the classification. The term is a reference to the eightfold way of Buddhism.

Gell-Mann, and, independently, George Zweig, went on, in 1964, to postulate the existence of quarks, particles of which hadrons are composed. The name was coined by Gell-Mann and is a reference to the novel ''Finnegans Wake'', by James Joyce ("Three quarks for Muster Mark!" book 2, episode 4). Zweig had referred to the particles as "aces", but Gell-Mann's name caught on. Quarks, antiquarks, and gluons were soon accepted as the underlying elementary objects in the study of the structure of hadrons. In 1972 he introduced with Harald Fritzsch the perfectly conserved quantum number 'color', and later with Heinrich Leutwyler quantum chromodynamics (QCD) as the gauge theory of the strong interaction (cf. references). The quark model is a part of QCD and has been robust enough to survive the discovery of new "flavours" of quarks.

Gell-Mann and Richard Feynman, publishing together, and an independent group of George Sudarshan and Robert Marshak, were the first to discover the vector and axial vector structure of the weak interaction in physics. This work followed the discovery of parity violation by Chien-Shiung Wu, as suggested by Chen Ning Yang and Tsung-Dao Lee.

In the 1990s Gell-Mann's interest turned to the emerging study of complexity. He played a central role in the founding of the Santa Fe Institute, where he continues to work as a Distinguished Professor. He wrote a popular science book about these matters, ''The Quark and the Jaguar: Adventures in the Simple and the Complex''. The title of the book is taken from a line of an Arthur Sze poem: "The world of the quark has everything to do with a jaguar circling in the night." Gell-Mann also is an avid birdwatcher, a collector of antiquities, and a keen linguist. He notably assisted S.A. Starostin in his reconstruction of the Proto-Human language.

George Johnson wrote a biography of Gell-Mann, which is entitled ''Strange Beauty: Murray Gell-Mann and the Revolution in 20th-Century Physics'', which he has criticized as inaccurate.

Timeline

Gell-Mann earned a bachelor's degree in physics from Yale University in 1948, and a PhD in physics from MIT in 1951. He was a postdoctoral fellow at the Institute for Advanced Study in 1951, and a visiting research professor at the University of Illinois at Urbana–Champaign from 1952 to 1953. He was a visiting associate professor at Columbia University and an associate professor at the University of Chicago in 1954-55 before moving to the California Institute of Technology, where he taught from 1955 until he retired in 1993. He was awarded a Nobel Prize in physics in 1969 for his contributions and discoveries concerning the classification of elementary particles and their interactions.

He is currently the Robert Andrews Millikan Professor of Theoretical Physics Emeritus at Caltech as well as a University Professor in the Physics and Astronomy Department of the University of New Mexico in Albuquerque, New Mexico and the Presidential Professor of Physics and Medicine at the University of Southern California. He is a member of the editorial board of the ''Encyclopædia Britannica''. In 1984 Gell-Mann co-founded the Santa Fe Institute—a non-profit theoretical research institute in Santa Fe, New Mexico—to study complex systems and disseminate the notion of a separate interdisciplinary study of complexity theory.

Personal life

Gell-Mann married Marcia Southwick in 1992, after the death of his first wife, J. Margaret Dow (d. 1981), whom he married in 1955. His children are Elizabeth Sarah Gell-Mann (b. 1956) and Nicholas Webster Gell-Mann (b. 1963); and he has a stepson, Nicholas Southwick Levis (b. 1978).

Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world.

He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster. In addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology. He held the Richard Chace Tolman professorship in theoretical physics at the California Institute of Technology.

Feynman was a keen popularizer of physics through both books and lectures, notably a 1959 talk on top-down nanotechnology called ''There's Plenty of Room at the Bottom'' and ''The Feynman Lectures on Physics''. Feynman also became known through his semi-autobiographical books (''Surely You're Joking, Mr. Feynman!'' and ''What Do You Care What Other People Think?'') and books written about him, such as ''Tuva or Bust!''

Feynman also had a deep interest in biology, and was a friend of the geneticist and microbiologist Esther Lederberg, who developed replica plating and discovered bacteriophage lambda. They had several mutual physicist friends who, after beginning their careers in nuclear research, moved for moral reasons into genetics, among them Max Delbruck, Leó Szilárd, Guido Pontecorvo, and Aaron Novick.

Biography

Early life

Richard Phillips Feynman was born on May 11, 1918, in Far Rockaway, Queens, New York. His family originated from Russia and Poland; both of his parents were Jewish. They were not religious and by his youth Feynman described himself as an "avowed atheist". Feynman (in common with the famous physicist Edward Teller) was a late talker; by his third birthday he had yet to utter a single word. The young Feynman was heavily influenced by his father, Melville, who encouraged him to ask questions to challenge orthodox thinking. From his mother, Lucille, he gained the sense of humor that he had throughout his life. As a child, he delighted in repairing radios and had a talent for engineering. His younger sister Joan also became a professional physicist.

Education

In high school, his IQ was determined to be 125—high, but "merely respectable" according to biographer James Gleick. Feynman later scoffed at psychometric testing. By 15, he had learned differential and integral calculus. Before entering college, he was experimenting with and re-creating mathematical topics, such as the half-derivative, utilizing his own notation. In high school, he was developing the mathematical intuition behind his Taylor series of mathematical operators. A member of the Arista Honor Society, in his last year in high school, Feynman won the New York University Math Championship; the large difference between his score and those of his closest competitors shocked the judges.

He applied to Columbia University, but was not accepted. Instead he attended the Massachusetts Institute of Technology, where he received a bachelor's degree in 1939, and in the same year was named a Putnam Fellow. While there, Feynman took every physics course offered, including a graduate course on theoretical physics while only in his second year.

He obtained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physics—an unprecedented feat—but did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a Ph.D. from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the Wheeler–Feynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was entitled "The Principle of Least Action in Quantum Mechanics".

The Manhattan Project

At Princeton, the physicist Robert R. Wilson encouraged Feynman to participate in the Manhattan Project—the wartime U.S. Army project at Los Alamos developing the atomic bomb. Feynman said he was persuaded to join this effort to build it before Nazi Germany developed their own bomb.

He was assigned to Hans Bethe's theoretical division, and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber.

He immersed himself in work on the project, and was present at the Trinity bomb test. Feynman claimed to be the only person to see the explosion without the very dark glasses or welder's lenses provided, reasoning that it was safe to look through a truck windshield, as it would screen out the harmful ultraviolet radiation.

As a junior physicist, he was not central to the project. The greater part of his work was administering the computation group of human computers in the Theoretical division (one of his students there, John G. Kemeny, later went on to co-write the computer language BASIC). Later, with Nicholas Metropolis, he assisted in establishing the system for using IBM punched cards for computation. Feynman succeeded in solving one of the equations for the project that were posted on the blackboards. However, they did not "do the physics right" and Feynman's solution was not used.

Feynman's other work at Los Alamos included calculating neutron equations for the Los Alamos "Water Boiler", a small nuclear reactor, to measure how close an assembly of fissile material was to criticality. On completing this work he was transferred to the Oak Ridge facility, where he aided engineers in devising safety procedures for material storage so that criticality accidents (for example, due to sub-critical amounts of fissile material inadvertently stored in proximity on opposite sides of a wall) could be avoided. He also did theoretical work and calculations on the proposed uranium hydride bomb, which later proved not to be feasible.

Feynman was sought out by physicist Niels Bohr for one-on-one discussions. He later discovered the reason: most physicists were too in awe of Bohr to argue with him. Feynman had no such inhibitions, vigorously pointing out anything he considered to be flawed in Bohr's thinking. Feynman said he felt as much respect for Bohr as anyone else, but once anyone got him talking about physics, he would become so focused he forgot about social niceties.

Due to the top secret nature of the work, Los Alamos was isolated. In Feynman's own words, "There wasn't anything to ''do'' there". Bored, he indulged his curiosity by learning to pick the combination locks on cabinets and desks used to secure papers. Feynman played many jokes on colleagues. In one case he found the combination to a locked filing cabinet by trying the numbers a physicist would use (it proved to be 27–18–28 after the base of natural logarithms, ''e'' = 2.71828...), and found that the three filing cabinets where a colleague kept a set of atomic bomb research notes all had the same combination. He left a series of notes as a prank, which initially spooked his colleague, Frederic de Hoffman, into thinking a spy or saboteur had gained access to atomic bomb secrets. On several occasions, Feynman drove to Albuquerque to see his ailing wife in a car borrowed from Klaus Fuchs, who was later discovered to be a real spy for the Soviets, transporting nuclear secrets in his car to Santa Fe.

On occasion, Feynman would find an isolated section of the mesa to drum in the style of American natives; "and maybe I would dance and chant, a little". These antics did not go unnoticed, and rumors spread about a mysterious Indian drummer called "Injun Joe". He also became a friend of laboratory head J. Robert Oppenheimer, who unsuccessfully tried to court him away from his other commitments after the war to work at the University of California, Berkeley.

Feynman alludes to his thoughts on the justification for getting involved in the Manhattan project in ''The Pleasure of Finding Things Out''. As mentioned earlier, he felt the possibility of Nazi Germany developing the bomb before the Allies was a compelling reason to help with its development for the US. However, he goes on to say that it was an error on his part not to reconsider the situation when Germany was defeated. In the same publication, Feynman also talks about his worries in the atomic bomb age, feeling for some considerable time that there was a high risk that the bomb would be used again soon so that it was pointless to build for the future. Later he describes this period as a "depression."

Early academic career

Following the completion of his Ph.D. in 1942, Feynman held an appointment at the University of Wisconsin–Madison as an assistant professor of physics. The appointment was spent on leave for his involvement in the Manhattan project. In 1945, he received a letter from Dean Mark Ingraham of the College of Letters and Science requesting his return to UW to teach in the coming academic year. His appointment was not extended when he did not commit to return. In a talk given several years later at UW, Feynman quipped, "It's great to be back at the only university that ever had the good sense to fire me".

After the war, Feynman declined an offer from the Institute for Advanced Study in Princeton, New Jersey, despite the presence there of such distinguished faculty members as Albert Einstein, Kurt Gödel, and John von Neumann. Feynman followed Hans Bethe, instead, to Cornell University, where Feynman taught theoretical physics from 1945 to 1950. During a temporary depression following the destruction of Hiroshima by the bomb produced by the Manhattan Project, he focused on complex physics problems, not for utility, but for self-satisfaction. One of these was analyzing the physics of a twirling, nutating dish as it is moving through the air. His work during this period, which used equations of rotation to express various spinning speeds, soon proved important to his Nobel Prize-winning work. Yet because he felt burned out, and had turned his attention to less immediately practical but more entertaining problems, he felt surprised by the offers of professorships from renowned universities. He gained a reputation for taking great care when giving explanations to his students and for making it a moral duty to make the topic accessible. His guiding principle was that if a topic could not be explained in a freshman lecture, it was not yet fully understood. Feynman gained great pleasure from coming up with such a "freshman-level" explanation, for example, of the connection between spin and statistics. What he said was that groups of particles with spin 1/2 "repel", whereas groups with integer spin "clump." This was a brilliantly simplified way of demonstrating how Fermi–Dirac statistics and Bose–Einstein statistics evolved as a consequence of studying how fermions and bosons behave under a rotation of 360°. This was also a question he pondered in his more advanced lectures and to which he demonstrated the solution in the 1986 Dirac memorial lecture. In the same lecture, he further explained that antiparticles must exist, for if particles only had positive energies, they would not be restricted to a so-called "light cone."

He opposed rote learning or unthinking memorization and other teaching methods that emphasized form over function. He put these opinions into action whenever he could, from a conference on education in Brazil to a State Commission on school textbook selection. ''Clear thinking'' and ''clear presentation'' were fundamental prerequisites for his attention. It could be perilous even to approach him when unprepared, and he did not forget the fools or pretenders.

During one sabbatical year, he returned to Newton's ''Principia Mathematica'' to study it anew; what he learned from Newton, he passed along to his students, such as Newton's attempted explanation of diffraction.

Caltech years

Feynman did significant work while at Caltech, including research in:

Quantum electrodynamics. The theory for which Feynman won his Nobel Prize is known for its accurate predictions. This theory was begun in the earlier years during Feynman's work at Princeton as a graduate student and continued while he was at Cornell. This work consisted of two distinct formulations, and it is a common error to confuse them or to merge them into one. The first is his path integral formulation, and the second is his Feynman diagrams. Both formulations contained his sum over histories method in which every possible path from one state to the next is considered, the final path being a ''sum'' over the possibilities (also referred to as sum-over-paths.) For a number of years he lectured to students at Caltech on his path integral formulation of quantum theory. The lecture notes have recently and very lovingly been reedited by Daniel F. Styer and published as a Dover paperback. Not only did Styer correct several hundred typographical and other minor errors, but he included many footnotes explaining, for example, several places where the author used heuristic or plausible reasoning. The second formulation of quantum electrodynamics (using Feynman diagrams) was specifically mentioned by the Nobel committee. The logical connection with the path integral formulation is interesting. Feynman did not prove that the rules for his diagrams followed mathematically from the path integral formulation. Some special cases were later proved by other people, but only in the real case, so the proofs don't work when spin is involved. The second formulation should be thought of as starting anew, but guided by the intuitive insight provided by the first formulation. Freeman Dyson published a paper in 1949 which, among many other things, added new rules to Feynman's which told how to actually implement Renormalization. Students everywhere learned and used the powerful new tool that Feynman had created. Eventually computer programs were written to compute Feynman diagrams, providing a tool of unprecedented power. It is possible to write such programs because the Feynman diagrams constitute a Formal language with a grammar.

Physics of the superfluidity of supercooled liquid helium, where helium seems to display a complete lack of viscosity when flowing. Applying the Schrödinger equation to the question showed that the superfluid was displaying quantum mechanical behavior observable on a macroscopic scale. This helped with the problem of superconductivity; however, the solution eluded Feynman. It was solved with the BCS theory of superconductivity, proposed by John Bardeen, Leon Neil Cooper, and John Robert Schrieffer.

A model of weak decay, which showed that the current coupling in the process is a combination of vector and axial currents (an example of weak decay is the decay of a neutron into an electron, a proton, and an anti-neutrino). Although E. C. George Sudarshan and Robert Marshak developed the theory nearly simultaneously, Feynman's collaboration with Murray Gell-Mann was seen as seminal because the weak interaction was neatly described by the vector and axial currents. It thus combined the 1933 beta decay theory of Enrico Fermi with an explanation of parity violation.

He also developed Feynman diagrams, a bookkeeping device which helps in conceptualizing and calculating interactions between particles in spacetime, notably the interactions between electrons and their antimatter counterparts, positrons. This device allowed him, and later others, to approach time reversibility and other fundamental processes. Feynman's mental picture for these diagrams started with the ''hard sphere'' approximation, and the interactions could be thought of as ''collisions'' at first. It was not until decades later that physicists thought of analyzing the nodes of the Feynman diagrams more closely. Feynman famously painted Feynman diagrams on the exterior of his van.

From his diagrams of a small number of particles interacting in spacetime, Feynman could then model all of physics in terms of those particles' spins and the range of coupling of the fundamental forces. Feynman attempted an explanation of the strong interactions governing nucleons scattering called the parton model. The parton model emerged as a complement to the quark model developed by his Caltech colleague Murray Gell-Mann. The relationship between the two models was murky; Gell-Mann referred to Feynman's partons derisively as "put-ons". In the mid 1960s, physicists believed that quarks were just a bookkeeping device for symmetry numbers, not real particles, as the statistics of the Omega-minus particle, if it were interpreted as three identical strange quarks bound together, seemed impossible if quarks were real. The Stanford linear accelerator deep inelastic scattering experiments of the late 1960s showed, analogously to Ernest Rutherford's experiment of scattering alpha particles on gold nuclei in 1911, that nucleons (protons and neutrons) contained point-like particles which scattered electrons. It was natural to identify these with quarks, but Feynman's parton model attempted to interpret the experimental data in a way which did not introduce additional hypotheses. For example, the data showed that some 45% of the energy momentum was carried by electrically neutral particles in the nucleon. These electrically neutral particles are now seen to be the gluons which carry the forces between the quarks and carry also the three-valued color quantum number which solves the Omega-minus problem. Feynman did not dispute the quark model; for example, when the fifth quark was discovered in 1977, Feynman immediately pointed out to his students that the discovery implied the existence of a sixth quark, which was duly discovered in the decade after his death.

After the success of quantum electrodynamics, Feynman turned to quantum gravity. By analogy with the photon, which has spin 1, he investigated the consequences of a free massless spin 2 field, and was able to derive the Einstein field equation of general relativity, but little more. However, the computational device that Feynman discovered then for gravity, "ghosts", which are "particles" in the interior of his diagrams which have the "wrong" connection between spin and statistics, have proved invaluable in explaining the quantum particle behavior of the Yang–Mills theories, for example QCD and the electro-weak theory.

In 1965, Feynman was appointed a foreign member of the Royal Society. At this time in the early 1960s, Feynman exhausted himself by working on multiple major projects at the same time, including a request, while at Caltech, to "spruce up" the teaching of undergraduates. After three years devoted to the task, he produced a series of lectures that eventually became the ''Feynman Lectures on Physics'', one reason that Feynman is still regarded as one of the greatest teachers of physics. He wanted a picture of a drumhead sprinkled with powder to show the modes of vibration at the beginning of the book. Outraged by many rock and roll and drug connections that could be made from the image, the publishers changed the cover to plain red, though they included a picture of him playing drums in the foreword. Feynman later won the Oersted Medal for teaching, of which he seemed especially proud.

His students competed keenly for his attention; he was once awakened when a student solved a problem and dropped it in his mailbox; glimpsing the student sneaking across his lawn, he could not go back to sleep, and he read the student's solution. The next morning his breakfast was interrupted by another triumphant student, but Feynman informed him that he was too late.

Partly as a way to bring publicity to progress in physics, Feynman offered $1000 prizes for two of his challenges in nanotechnology, claimed by William McLellan and Tom Newman, respectively. He was also one of the first scientists to conceive the possibility of quantum computers.

Many of his lectures and other miscellaneous talks were turned into books, including ''The Character of Physical Law'' and ''QED: The Strange Theory of Light and Matter''. He gave lectures which his students annotated into books, such as ''Statistical Mechanics'' and ''Lectures on Gravity''. ''The Feynman Lectures on Physics'' occupied two physicists, Robert B. Leighton and Matthew Sands as part-time co-authors for several years. Even though they were not adopted by most universities as textbooks, the books continue to be bestsellers because they provide a deep understanding of physics. As of 2005, ''The Feynman Lectures on Physics'' has sold over 1.5 million copies in English, an estimated 1 million copies in Russian, and an estimated half million copies in other languages.

In 1974, Feynman delivered the Caltech commencement address on the topic of cargo cult science, which has the semblance of science but is only pseudoscience due to a lack of "a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty" on the part of the scientist. He instructed the graduating class that "The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that."

In 1984–86, he developed a variational method for the approximate calculation of path integrals which has led to a powerful method of converting divergent perturbation expansions into convergent strong-coupling expansions (variational perturbation theory) and, as a consequence, to the most accurate determination of critical exponents measured in satellite experiments.

In the late 1980s, according to "Richard Feynman and the Connection Machine", Feynman played a crucial role in developing the first massively parallel computer, and in finding innovative uses for it in numerical computations, in building neural networks, as well as physical simulations using cellular automata (such as turbulent fluid flow), working with Stephen Wolfram at Caltech. His son Carl also played a role in the development of the original Connection Machine engineering; Feynman influencing the interconnects while his son worked on the software.

Feynman diagrams are now fundamental for string theory and M-theory, and have even been extended topologically. The ''world-lines'' of the diagrams have developed to become ''tubes'' to allow better modeling of more complicated objects such as ''strings'' and ''membranes''. However, shortly before his death, Feynman criticized string theory in an interview: "I don't like that they're not calculating anything," he said. "I don't like that they don't check their ideas. I don't like that for anything that disagrees with an experiment, they cook up an explanation—a fix-up to say, 'Well, it still might be true. These words have since been much-quoted by opponents of the string-theoretic direction for particle physics.

Challenger disaster

Feynman played an important role on the Presidential Rogers Commission, which investigated the ''Challenger'' disaster. Feynman devoted the latter half of his book ''What Do You Care What Other People Think?'' to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. He concluded that the NASA management's space shuttle reliability estimate was fantastically unrealistic. He warned in his appendix to the commission's report, "For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled." He also rebuked some mathematicians for their exclusivity, saying "I have great suspicion that [mathematicians] don't know, that this stuff is wrong, and that they're intimidating people."

Personal life

While researching for his Ph.D., Feynman married his first wife, Arline Greenbaum (often spelled ''Arlene''). She was diagnosed with tuberculosis, but she and Feynman were careful, and he never contracted it. She succumbed to the disease in 1945. This portion of Feynman's life was portrayed in the 1996 film ''Infinity'', which featured Feynman's daughter Michelle in a cameo role.

He was married a second time in June 1952, to Mary Louise Bell of Neodesha, Kansas; this marriage was brief and unsuccessful: He later married Gweneth Howarth from Ripponden, Yorkshire, who shared his enthusiasm for life and spirited adventure. Besides their home in Altadena, California, they had a beach house in Baja California, purchased with the prize money from Feynman's Nobel Prize, his one third share of $55,000. They remained married until Feynman's death. They had a son, Carl, in 1962, and adopted a daughter, Michelle, in 1968. Mathematics was a common interest for father and son; they both entered the computer field as consultants and were involved in advancing a new method of using multiple computers to solve complex problems—later known as parallel computing. The Jet Propulsion Laboratory retained Feynman as a computational consultant during critical missions. One co-worker characterized Feynman as akin to Don Quixote at his desk, rather than at a computer workstation, ready to do battle with the windmills.

Feynman traveled a great deal, notably to Brazil, where he gave courses at the CBPF (Brazilian Center for Physics Research) and near the end of his life schemed to visit the Russian land of Tuva, a dream that, because of Cold War bureaucratic problems, never became reality. The day after he died, a letter arrived for him from the Soviet government giving him authorization to travel to Tuva. Out of his enthusiastic interest in reaching Tuva came the phrase "Tuva or Bust" (also the title of a book about his efforts to get there), which was tossed about frequently amongst his circle of friends in hope that they, one day, could see it firsthand. The documentary movie ''Genghis Blues'' mentions some of his attempts to communicate with Tuva, and chronicles the successful journey there by his friends.

Responding to Hubert Humphrey's congratulation for his Nobel Prize, Feynman admitted to a long admiration for the then vice president. In a letter to an MIT professor dated December 6, 1966, Feynman expressed interest in running for the governor of California.

Feynman took up drawing at one time and enjoyed some success under the pseudonym "Ofey", culminating in an exhibition dedicated to his work. He learned to play a metal percussion instrument (''frigideira'') in a samba style in Brazil, and participated in a samba school.

In addition, he had some degree of synesthesia for equations, explaining that the letters in certain mathematical functions appeared in color for him, even though invariably printed in standard black-and-white.

According to ''Genius'', the James Gleick–authored biography, Feynman tried LSD during his professorship at Caltech. Somewhat embarrassed by his actions, Feynman largely sidestepped the issue when dictating his anecdotes; he mentions it in passing in the "O Americano, Outra Vez" section, while the "Altered States" chapter in ''Surely You're Joking, Mr. Feynman!'' describes only marijuana and ketamine experiences at John Lilly's famed sensory deprivation tanks, as a way of studying consciousness.

Death

Feynman developed two rare forms of cancer, Liposarcoma and Waldenström's macroglobulinemia, dying shortly after a final attempt at surgery for the former on February 15, 1988, aged 69. His last recorded words are noted as "I'd hate to die twice. It's so boring."

Popular legacy

On May 4, 2005, the United States Postal Service issued the ''American Scientists'' commemorative set of four 37-cent self-adhesive stamps in several configurations. The scientists depicted were Richard Feynman, John von Neumann, Barbara McClintock and Josiah Willard Gibbs. Feynman's stamp, sepia-toned, features a photograph of a 30-something Feynman and eight small Feynman diagrams. The stamps were designed by artist Victor Stabin under the direction of U.S. Postal Service art director Carl T. Herrman.

The main building for the Computing Division at Fermilab is named the "Feynman Computing Center" in his honor.

The principal character in Thomas A. McMahon's well-regarded 1970 novel, ''Principles of American Nuclear Chemistry: A Novel'', is modeled on Feynman.

Real Time Opera premiered its opera ''Feynman'' at the Norfolk (CT) Chamber Music Festival in June 2005.

On the 20th anniversary of Feynman's death, composer Edward Manukyan dedicated a piece for solo clarinet to his memory. It was premiered by Doug Storey, the principal clarinetist of the Amarillo Symphony.

In 2009 and 2010, respectively, clips of an interview with Feynman were used by composer John Boswell as part of the Symphony of Science project in the second and fifth installment of his science educational videos, "We Are All Connected" and "The Poetry of Reality".

In 1998, a photo of Richard Feynman giving a lecture was part of the poster series commissioned by Apple Computer for their "Think Different" advertising campaign.

Bibliography

Selected scientific works

Textbooks and lecture notes

''The Feynman Lectures on Physics'' is perhaps his most accessible work for anyone with an interest in physics, compiled from lectures to Caltech undergraduates in 1961–64. As news of the lectures' lucidity grew, a number of professional physicists and graduate students began to drop in to listen. Co-authors Robert B. Leighton and Matthew Sands, colleagues of Feynman, edited and illustrated them into book form. The work has endured, and is useful to this day. They were edited and supplemented in 2005 with "Feynman's Tips on Physics: A Problem-Solving Supplement to the Feynman Lectures on Physics" by Michael Gottlieb and Ralph Leighton (Robert Leighton's son), with support from Kip Thorne and other physicists.

Includes ''Feynman's Tips on Physics'' (with Michael Gottlieb and Ralph Leighton), which includes four previously unreleased lectures on problem solving, exercises by Robert Leighton and Rochus Vogt, and a historical essay by Matthew Sands.

James Randi (born Randall James Hamilton Zwinge; August 7, 1928) is a Canadian-American stage magician and scientific skeptic best known as a challenger of paranormal claims and pseudoscience. Randi is the founder of the James Randi Educational Foundation. Randi began his career as a magician named The Amazing Randi, but after retiring at age 60, he began investigating paranormal, occult, and supernatural claims, which he collectively calls "woo-woo."

Although often referred to as a "debunker," Randi rejects that title owing to its perceived bias, instead describing himself as an "investigator." He has written about the paranormal, skepticism, and the history of magic. He was a frequent guest on ''The Tonight Show Starring Johnny Carson'' and was occasionally featured on the television program ''Penn & Teller: Bullshit!''. The JREF sponsors The One Million Dollar Paranormal Challenge offering a prize of US$1,000,000 to eligible applicants who can demonstrate evidence of any paranormal, supernatural or occult power or event under test conditions agreed to by both parties.

Early life

Randi was born in Toronto, Ontario, Canada, and has a younger brother and sister. He took up magic after reading magic books while spending 13 months in a body cast following a bicycle accident. He confounded doctors who expected he would never walk again. Although a brilliant student, Randi often skipped school, and he dropped out of high school at 17 to perform as a conjurer in a carnival roadshow. In his twenties, Randi posed as a psychic to establish that they were actually doing simple tricks and briefly wrote an astrological column in the Canadian tabloid ''Midnight'' under the name "Zo-ran," by simply shuffling up items from newspaper astrology columns and pasting them randomly into a column. In his thirties, Randi worked in Philippine night clubs and all across Japan. He witnessed many tricks that were presented as being supernatural. One of his earliest reported experiences is that of seeing an evangelist using the "one-ahead" routine to convince churchgoers of his divine powers.

Randi worked as a professional stage magician, or "conjurer" as he prefers to be called, and escapologist beginning in 1946, initially under his birth name, Randall Zwinge, and then as The Amazing Randi. Early in his career, Randi was part of numerous stunts involving his escape from jail cells and safes. On February 7, 1956, he appeared live on ''The Today Show'', remaining in a sealed metal coffin submerged in a hotel swimming pool for 104 minutes, breaking what was said to be Houdini's record of 93 minutes.

Randi was the host of ''The Amazing Randi Show'' on New York radio station WOR in the mid 1960s. This radio show, which filled Long John Nebel's old slot with similar content after Nebel went to WNBC in 1962, had frequent pro-paranormal guests, including Randi's then-friend James Moseley. Randi, in turn, spoke at Moseley's 1967 Fourth Congress of Scientific Ufologists in New York City, stating, "Let's not fool ourselves. There are some garden variety liars involved in all this. But in among all the trash and nonsense perpetrated in the name of Ufology, I think there is a small grain of truth."

Randi also hosted numerous television specials and went on several world tours. Then Randi appeared as "The Amazing Randi" on a television show titled ''Wonderama'' from 1967 to 1972, and as host of a failed revival of the 1950s children's show ''The Magic Clown'' in 1970. In the February 2, 1974, issue of ''Abracadabra'' (a British conjuring magazine), Randi defined the magic community, saying, "I know of no calling which depends so much upon mutual trust and faith as does ours." In the December 2003 issue of ''The Linking Ring'', the monthly publication of The International Brotherhood of Magicians, ''Points to Ponder: Another Matter of Ethics,'' p. 97, it is stated, "Perhaps Randi's ethics are what make him Amazing" and "The Amazing Randi not only talks the talk, he walks the walk."

During Alice Cooper's 1973–1974 tour, Randi performed as the dentist and executioner on stage, and designed and built several of the stage props, including the guillotine. Shortly after that, in February 1975, Randi escaped from a straitjacket while suspended upside-down over Niagara Falls in the winter on the Canadian TV program ''World of Wizards''.

Randi was once accused of actually using "psychic powers" to perform acts such as spoon bending. James Alcock relates this incident, which occurred at a meeting where Randi was duplicating the performances of Uri Geller: A professor from the University at Buffalo shouted out that Randi was a fraud. Randi said, "Yes, indeed, I'm a trickster, I'm a cheat, I'm a charlatan, that's what I do for a living. Everything I've done here was by trickery." The professor shouted back: "That's not what I mean. You're a fraud because you're pretending to do these things through trickery, but you're actually using psychic powers and misleading us by not admitting it." The famous author and believer in spiritualism Arthur Conan Doyle had years earlier made a similar accusation against the magician Harry Houdini. A similar event involved Senator Claiborne Pell. Pell believed in psychic phenomena. When Randi demonstrated viewing a hidden drawing by using trickery, Pell refused to believe that it was a trick, saying, "I think Randi may be a psychic and doesn't realize it."

Author

Randi is author of ''Conjuring'' (1992), a biographical history of noted magicians. The book is subtitled: ''Being a Definitive History of the Venerable Arts of Sorcery, Prestidigitation, Wizardry, Deception, & Chicanery and of the Mountebanks & Scoundrels Who have Perpetrated these Subterfuges on a Bewildered Public, in short, MAGIC!''. The book selects the most influential magicians and explains their history in the context of strange deaths and careers on the road. This work expanded on the 1976 book ''Houdini, His Life and Art'', co-authored with Bert Randolph Sugar, which focused on Houdini and his cohorts. Randi also wrote a children's book in 1989 titled ''The Magic World of the Amazing Randi'', which introduced children to magic tricks. In addition to his magic books, he has written several educational works about the paranormal and pseudoscientific. These include biographies of Uri Geller and Nostradamus as well as reference material on other major paranormal figures. He is currently working on ''A Magician in the Laboratory'', which recounts his application of skepticism to science, though in January 2011, he expressed doubts as to whether it would be finished. He is a member of the all-male literary banqueting club the Trap Door Spiders, which served as the basis of Isaac Asimov's fictional group of mystery solvers the Black Widowers.

Skeptic

Randi entered the international spotlight in 1972 when he publicly challenged the claims of Uri Geller. Randi accused Geller of being nothing more than a charlatan and a fraud who used standard magic tricks to accomplish his allegedly paranormal feats, and he supported his claims in the book ''The Truth About Uri Geller''. Geller unsuccessfully sued Randi for $15 million in 1991. Geller's suit against the Committee for Scientific Investigation of Claims of the Paranormal (CSICOP) was thrown out in 1995, and he was ordered to pay $120,000 for filing a frivolous lawsuit.

Randi was a founding fellow and prominent member of CSICOP. During the period when Geller was filing numerous civil suits against him, CSICOP's leadership, wanting to avoid becoming a target of Geller's litigation, requested that Randi refrain from commenting on Geller. Randi refused and resigned. However, he still maintains a respectful relationship with the group and frequently writes articles for its magazine.

Randi has gone on to write several books criticizing beliefs and claims regarding the paranormal. He has also demonstrated flaws in studies suggesting the existence of paranormal phenomena; in his Project Alpha hoax, Randi revealed that he had been able to orchestrate a three-year-long compromise of a privately funded psychic research experiment. The hoax became a scandal and demonstrated the shortcomings of many paranormal research projects at the university level.

Randi has appeared on numerous TV shows, sometimes to directly debunk the claimed abilities of fellow guests. In a 1981 appearance on ''That's My Line'', Randi appeared opposite psychic James Hydrick, who claimed that he could move things with his mind and demonstrated this ability on live television by apparently turning a page in a telephone book without touching it. Randi, having determined that Hydrick was surreptitiously blowing on the book, arranged packaging peanuts (polystyrene foam shapes) on the table in front of the telephone book for the demonstration, preventing Hydrick from demonstrating his abilities, which would have been exposed when the blowing moved the packaging. Many years later, Hydrick admitted his fraud.

Randi was awarded a MacArthur Foundation Genius award in 1986. The money was used for Randi's comprehensive exposé of faith healers, including Peter Popoff, W.V. Grant and Ernest Angley. When Popoff was exposed, he was forced to declare bankruptcy within the year.

In 1988, Randi tested the gullibility of the media by perpetrating a fraud of his own. By teaming up with Australia's ''60 Minutes'' program and by releasing a fake press package, he built up publicity for a spirit channeler named Carlos who was actually artist Jose Alvarez, a friend of Randi's. Randi would tell him what to say through sophisticated radio equipment. The media and the public were taken in, as no reporter bothered to check Carlos's credentials and history, which were all fabricated. The hoax was exposed on ''60 Minutes''; Carlos and Randi explained how they pulled it off.

In the book ''The Faith Healers'', Randi explains his anger and relentlessness as arising out of compassion for the helpless victims of frauds. Randi has also been critical of João de Deus (John of God), a self-proclaimed psychic surgeon who has received international attention. Randi observed, referring to psychic surgery, "To any experienced conjurer, the methods by which these seeming miracles are produced are very obvious."

In 1982, Randi verified the abilities of Arthur Lintgen, a Philadelphia physician who is able to determine the classical music recorded on a vinyl LP solely by examining the groove on the record. However, Lintgen does not claim to have any paranormal ability, merely knowledge of the way that the groove forms patterns on particular recordings.

James Randi stated that Daniel Dunglas Home, who allegedly could play an accordion that was locked in a cage, without touching it, was caught cheating on a few occasions, but the episodes were never made public, and that the accordion in question was a one-octave mouth organ that Home concealed under his large moustache. James Randi writes that one-octave mouth organs were found in Home's belongings after his death. According to Randi 'around 1960' William Lindsay Gresham told Randi he had seen these mouth organs in the Home collection at the Society for Psychical Research. Eric Dingwall, who catalogued Home's collection on its arrival at the SPR does not record the presence of the mouth organs. According to Peter Lamont, the author of an extensive Home biography, "It is unlikely Dingwall would have missed these or did not make them public."

James Randi Educational Foundation (JREF)

In 1996, Randi established the James Randi Educational Foundation (JREF). Randi and his colleagues update JREF's blog, Swift. Topics have included the mathematics of the one-seventh area triangle. Randi also contributes a regular column, titled "'Twas Brillig," to The Skeptics Society's Skeptic Magazine. In his weekly commentary, Randi often gives examples of what he considers the nonsense that he deals with every day.

He has regularly featured on many podcasts that can be found online, including The Skeptics Society's official podcast Skepticality and the Center for Inquiry's official podcast Point of Inquiry. From September 2006 onwards, he has occasionally contributed to The Skeptics' Guide to the Universe podcast with a column titled "Randi Speaks." In addition, "The Amazing Show" is a podcast in which Randi shares various anecdotes in an interview format.

Views on religion

In his essay "Why I Deny Religion, How Silly and Fantastic It Is, and Why I'm a Dedicated and Vociferous Bright", Randi, who identifies himself as an atheist, has stated that many accounts in religious texts, including the virgin birth, the miracles of Jesus Christ, and the parting of the Red Sea by Moses, are not believable. For example, Randi refers to the Virgin Mary as being "impregnated by a ghost of some sort, and as a result produced a son who could walk on water, raise the dead, turn water into wine, and multiply loaves of bread and fishes" and questions how Adam and Eve "could have two sons, one of whom killed the other, and yet managed to populate the earth without committing incest." He writes that, compared to the Bible, "''The Wizard of Oz'' is more believable. And more fun." In ''An Encyclopedia of Claims, Frauds, and Hoaxes of the Occult and Supernatural'', he looks at a variety of spiritual practices skeptically. Of the meditation techniques of Guru Maharaj Ji (Prem Rawat) he writes: "Only the very naive were convinced that they had been let in on some sort of celestial secret."

The One Million Dollar Paranormal Challenge

The James Randi Educational Foundation (JREF) currently offers a prize of one million U.S. dollars to eligible applicants who can demonstrate a supernatural ability under agreed-upon scientific testing criteria. Similar to the paranormal challenges of John Nevil Maskelyne and Houdini, in 1964, Randi put up $1,000 of his own money payable to anyone who could provide objective proof of the paranormal. Since then, the prize money has grown to the current $1,000,000, and has formal published rules. No one has progressed past the preliminary test, which is set up with parameters agreed to by both Randi and the applicant. He refuses to accept any challengers who might suffer serious injury or death as a result of the testing.

On ''Larry King Live'', March 6, 2001, Larry King asked Sylvia Browne if she would take the challenge and she agreed. Then Randi appeared with Browne on ''Larry King Live'' on September 3, 2001, and she again accepted the challenge. However, she has refused to be tested and Randi keeps a clock on his website recording the number of weeks that have passed since Browne accepted the challenge without following through. During ''Larry King Live'' on June 5, 2001, Randi challenged Rosemary Altea to undergo testing for the million dollars. However, Altea would not even address the question. Instead Altea, in part, replied "I agree with what he says, that there are many, many people who claim to be spiritual mediums, they claim to talk to the dead. There are many people, we all know this. There are cheats and charlatans everywhere." Then on January 26, 2007, Altea and Randi again appeared on ''Larry King Live''. Once again, she refused to answer whether or not she would take the One Million Dollar Paranormal Challenge.

Starting on April 1, 2007, only those with an already existing media profile and the backing of a reputable academic were allowed to apply for the challenge. The resources freed up by not having to test obscure and possibly mentally ill claimants will then be used to more aggressively challenge notorious high-profile alleged psychics and mediums such as Sylvia Browne, Allison DuBois and John Edward with a campaign in the media.

JREF maintains a public log of past participants in the Million Dollar Challenge.

Legal disputes

Randi has been involved in a variety of legal disputes but claims that he has "never paid even one dollar or even one cent to anyone who ever sued me." However, he says, he has paid out large sums to personally defend himself in these suits.

Eldon Byrd

A Baltimore District Court found Randi guilty of defaming Byrd for calling him a "convicted child molester" because although Byrd had been found guilty of child pornography offences and admitted to molestation, the admission was part of a plea bargain so he was not actually convicted. No damages were awarded to Byrd.

Uri Geller

According to Randi, Geller tried to sue Randi a number of times, but never won, save for a ruling in a Japanese court that ordered Randi to pay Geller one third of one percent of what Geller had demanded, but this ruling was canceled, and the matter dropped when Geller decided to concentrate on another legal matter. Randi later stated that the phrase "shot himself in the head" was a metaphor that had been lost in translation. He had made a similar statement in English three years earlier in a Toronto newspaper: "The scientist shot himself after I showed him how the key bending trick was done." In 1991, Randi commented that Uri Geller's public performances were of the same quality as those found on the backs of cereal boxes. Geller sued both Randi and CSICOP. CSICOP argued that the organization was not responsible for Randi's statements. The court agreed that including CSICOP was frivolous and dropped them from the action, leaving Randi to face the action alone. Geller was ordered to pay substantial damages to CSICOP. Randi and Geller subsequently settled their dispute out of court, the details of which have been kept confidential. The settlement also included an agreement that Geller would not pursue Randi for the award in the Japanese case or other outstanding cases.

Other

Allison DuBois, on whose life the television series ''Medium'' was based, threatened Randi with legal action for using a photo of her from her website in his December 17, 2004, commentary without her permission. Randi removed the photo, and now uses a caricature of DuBois when mentioning her on his site, beginning with his December 23, 2005, commentary.

Late in 1996, Randi launched a libel suit against a Toronto-area psychic named Earl Gordon Curley. Curley had made multiple objectionable comments about Randi on Usenet. Despite prodding Randi via Usenet to sue (Curley's comments had implied that if Randi did not sue, then his allegations must be true), Curley seemed entirely surprised when Randi actually retained Toronto's largest law firm and initiated legal proceedings. The suit was eventually dropped in 1998 when Earl Curley died at the age of 51.

Sniffex, producer of a dowsing bomb detection device, unsuccessfully sued Randi and the JREF in 2007. Sniffex sued Randi for his comments regarding a government test in which the Sniffex device failed. The company was later investigated and charged with fraud.

Personal life

In 1987, Randi became a naturalized citizen of the United States. Randi has said that one reason he became an American citizen was an incident while on tour with Alice Cooper where the Royal Canadian Mounted Police searched the band's lockers during a performance. Nothing was found, yet the RCMP destroyed the room.

In February 2006, Randi underwent coronary artery bypass surgery. In early February 2006, he was declared to be in stable condition and "receiving excellent care" with his recovery proceeding well. The weekly commentary updates to his website were made by guests while he was hospitalized. Randi recovered after his surgery and was able to help organize and attend the 2007 Amazing Meeting in Las Vegas, Nevada (an annual convention of scientists, magicians, skeptics, atheists and freethinkers).

Randi was diagnosed with intestinal cancer in June 2009. He had a ping pong ball-sized tumor removed from his intestines during laparoscopic surgery. He announced this a week later at the July 2009 The Amazing Meeting as well as the fact that he was scheduled to begin chemotherapy in the following weeks. He also said at the conference: "One day, I'm gonna die. That's all there is to it. Hey, it's too bad, but I've got to make room. I'm using a lot of oxygen and such—I think it's good use of oxygen myself, but of course, I'm a little prejudiced on the matter." Randi also said that after he is gone he does not want his fans to bother with a museum of magic named after him or burying him in a fancy tomb. Instead, he said, "I want to be cremated, and I want my ashes blown in Uri Geller's eyes." Randi underwent his final chemotherapy session on December 31, 2009, as he explained in a January 12, 2010 video in which he related that his chemotherapy experience was not as unpleasant as he had imagined. In a video posted April 12, 2010, Randi stated that he has been given a clean bill of health.

In a March 21, 2010 blog entry, Randi came out as gay, a move he explained was inspired by seeing the 2008 biographical drama film ''Milk'', in which Sean Penn portrayed Harvey Milk, the first openly gay man to be elected to public office in California.
