Mimeographed notes. From Gemini AI: "Quantum Electrodynamics and Meson Theories" ​ was, in fact, an intensive lecture course that Feynman taught between February 6 and March 2, 1950. ​Location: The California Institute of Technology (Caltech). ​The Context: Caltech was desperately trying to recruit him. To "seduce" him into leaving Cornell, they invited him to be a visiting professor. Feynman accepted the invitation to escape the harsh New York winter (Ithaca) and to see what life in California would be like. ​The Lecture Notes: What we know today under this title are the mimeographed notes prepared by students Carl W. Helstrom and Malvin A. Ruderman, who attended the classes. These notes are extremely rare and valuable because they show Feynman applying his newly created "Feynman Diagrams" not only to electrodynamics (QED) but also to the physics of mesons (nuclear particles), which was the frontier of physics at the time. ​Why was this important? ​The Permanent Move: It was during this February 1950 visit that Feynman fell in love with Caltech and the atmosphere of Pasadena. Shortly thereafter, he accepted the offer to become the Richard Chace Tolman Professor of Theoretical Physics there, a position he held for the rest of his life. ​Pedagogy of Diagrams: It was one of the first times he formally taught his diagrammatic methods to graduate students outside of his "bubble" at Cornell. ​Career Transition: These classes marked the end of his phase focused exclusively on QED and the beginning of his interest in high-energy physics and complex subatomic particles. ​Therefore, in February 1950, he was soaking up the California sun and convincing Caltech that he was the most brilliant physicist of his generation.…

First editions of three scarce mimeographed lecture series documenting Feynman's teaching more than a decade before the Lectures on Physics. Compiled from graduate students' classroom notes and preserved with extensive contemporary annotations, they provide unusually early evidence of his developing work in quantum electrodynamics, his turn toward particle physics, and the emergence of Feynman diagrams. The set comes from the library of Charles Hewitt Dix (1905-1984), Caltech professor of geophysics from 1948 to 1973, who evidently attended the courses. Housed in two contemporary spring binders, the lectures are accompanied by Dix's meticulous handwritten notes and problem sets, offering a rare view of how Feynman's methods were received by colleagues and advanced students. A leading exploration geophysicist, Dix joined Caltech after senior industry roles, remained on the faculty for 25 years, served as a Fulbright Fellow in Tokyo, lectured internationally for the US State Department, and authored influential works including Seismic Prospecting for Oil (1952); his archive is now in Caltech's special collections. Feynman arrived at Caltech after an unsettled period at Cornell and, invited by Robert Bacher, delivered "Quantum Electrodynamics and Meson Theories" in February-March 1950 before accepting a permanent chair and returning in 1951 with "High Energy Phenomena and Meson Theories". Aimed at graduate students and faculty, these lectures already deploy Feynman diagrams - then new and not yet widely accepted beyond the quantum electrodynamics community - as they began to enter high-energy physics. The student compilers included Carl W. Helstrom, later a pioneer of quantum information theory; Malvin A. Ruderman of Columbia; and William Karzas, later associated with Murray Gell-Mann at RAND. Produced in very small numbers for local circulation and often discarded, surviving copies are rare; only one earlier Feynman lecture series is known, the untraced Cornell "Quantum Electrodynamics" notes of autumn 1949. The first binder contains the mimeographed notes for the 1950 and 1951 lecture series, both with negligible institutional representation and scant auction history. The second holds the 1953 "Quantum Electrodynamics" notes from Feynman's three-semester quantum mechanics course, compiled by Albert Roach Hibbs and later forming the basis of his 1961 "Quantum Electrodynamics"; these too are untraced institutionally or commercially. Dix's extensive holograph annotations - outlining course aims, citing lectures, and adding summaries such as "Q.M. explains everything except Nuclear & Mesons / Gravity / Superconductivity / Superfluidity / Evaluation of Universe" - enrich the volume, alongside his wry note that Feynman was "now going to talk about 'real' things!"

Three mimeographed lectures and 83 leaves of holograph notes in the hand of Charles Hewitt Dix, bound together in two vols, quarto. With figures and diagrams in the text.

First edition. FEYNMAN'S UNPUBLISHED LECTURES ON MESON THEORY. First and only edition, extremely rare, of the mimeographed notes of Feynman's lecture course on meson theory, delivered as a visiting lecturer at Caltech (to which he moved permanently in the following year). Feynman had developed his distinctive diagrammatic approach while attempting to solve the problem of divergences in quantum electrodynamics (QED), the quantum theory of the interactions between electrically charged particles and the electromagnetic field (between electrons and photons, for example). "What captured most theorists' attention soon after the war was not electron physics, but rather the embarrassment of riches suddenly pouring forth from the new accelerators. A flood of new particles, similar to but in many ways distinct from the familiar electrons and photons, surprised physicists when they began to probe high-energy interactions with the aid of accelerators, rather than relying only upon cosmic rays. As quickly became clear, the new particles - dubbed 'mesotrons' or 'mesons', since the masses of many of them were intermediate between electrons and protons - interacted with each other differently than electrons and photons did" (Kaiser, p. 57). Feynman became interested in meson theory while he was still perfecting his understanding of QED, but his ideas in this area remain unpublished (see below) - these notes are thus a key historical record of Feynman's work on meson theory. Appearing 13 years before his famous three-volume Lectures on Physics, these particular notes were never published again, either separately or as part of his Selected Papers. They were probably produced in very small numbers for the graduate students and fellow faculty members who attended this advanced course. Widely regarded as the most brilliant, influential, and iconoclastic figure in theoretical physics in the post-World War II era, Feynman shared the Nobel Prize in Physics 1965 with Sin-Itiro Tomonaga and Julian Schwinger "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles." "Mark Kac, the eminent Polish-American mathematician, wrote: 'In science, as well as in other fields of human endeavor, there are two kinds of geniuses: the 'ordinary' and the 'magicians'. An ordinary genius is a fellow that you and I would be just as good as, if we were only many times better. There is no mystery as to how his mind works. Once we understand what he has done, we feel certain that we, too, could have done it. It is different with magicians . the working of their minds is for all intents and purposes incomprehensible . Richard Feynman [was] a magician of the highest caliber'" (Biographical Memoirs of Fellows of the Royal Society of London 48 (2002), p. 99). Not on OCLC. We are not aware of any other copy having appeared in commerce. Provenance: Kenneth Hedberg (signature on title). Hedberg (1920-2019) graduated from Oregon State College (BS, 1943) and the California Institute of Technology (Ph. D., 1948), having studied chemistry at both institutions. While at Caltech, Hedberg studied under Verner Schomaker and interacted frequently with Linus Pauling. In 1956 Hedberg returned to Oregon State College where he joined the faculty of the chemistry department. Hedberg was elected a fellow of the American Physical Society and the American Association for the Advancement of Science. He was also elected to membership of the Norwegian Academy of Science and Letters. At the end of the 1940s, physics was undergoing an extraordinary period of turmoil. "Newly discovered elementary particles, mesons and the like, were proliferating madly in the newly built particle accelerators. The elementary particle physics zoo was becoming embarrassingly crowded, so crowded in fact that it wasn't clear which of the new blips on chart recorders and new tracks in bubble chambers might really represent new elementary particles and which were simply rearrangements of existing ones" (Krauss, p. 169). The most important of these new particles were the mesons, and it was actually in the study of a problem in meson theory that Feynman became convinced that his own methods were correct and represented a real advance. The story is related by Schweber (pp. 454-6). At the January 1949 meeting of the American Physical Society in New York, Murray Slotnick, a student of Heitler and Bethe, gave a talk in which he described his calculation, in a so-called pseudoscalar meson theory, of the interaction between a neutron and the electrostatic field of an electron. Oppenheimer, who was in the audience, claimed that Slotnick's results must be wrong, as they contradicted a theorem of Case, a postdoc at the Institute for Advanced Study. "When Feynman arrived in New York that evening, he was told what had happened at the session. He received a report on the calculations of Slotnick, the 'numbers' he had obtained after long and laborious computations and Oppenheimer's slashing criticism. He was then asked to comment on the validity of Slotnick's results in the light of 'Case's theorem'. Feynman had not heard of this theorem. In fact, up to that point he had not interested himself in meson-theoretic calculations at all. However, between the results of a person who had calculated 'numbers' and those of a formalist, the choice was clear. To corroborate his hunch that Slotnick was right, he got someone to explain to him what was meant by pure charged and symmetric meson theory, by pseudoscalar and pseudovector coupling, and he readily translated this information into the rules to compute the relevant matrix elements using his methods. He spent a few hours that evening calculating the difference between the proton and neutron electric form factor in various meson theories with both pseudoscalar and pseudovector couplings. The next morning he got a hold of Slotnick in order to compare his results with those that Slotnick had obtained, 'be.…

Lancaster, American Physical Society, 1949. Royal8vo. In contemporary full red cloth with gilt lettering to spine. In "The Physical Review", Second Series, Volume 76, Number 6, No. 76. Entire issue offered. From the library of Dean E. Wooldridge. His name in gilt lettering to lower part of spine. Very fine and clean. Pp. 749-760" 769-789. First appearance of Feyman's landmark Quantum Electrodynamics (QED) illustrated but his famous Feynman-Diagrams which "revolutionized nearly every aspect of theoretical physics" (Kaiser, Physics and Feynman's Diagrams). The whole field of quantum electrodynamics advanced greatly because of this graphical formalism, which allowed researchers to communicate in an effective manner. Feynman, Schwinger and Tomonago shared the 1965 Nobel Prize in Physics "for their fundamental work in quantum electrodynamics, with deep ploughing consequences for the physics of elementary particles"."At Cornell, Feynman perfected his approach to quantum theory, melding several of his prewar insights with the more pragmatic, numbers-driven approach he had honed during the war. One of his first tasks was to publish a long article, based on his dissertation, that presented a brand-new approach to quantum mechanics. Published in 1948 under the title, 'Space-Time Approach to Non-relativistic Quantum Mechanics'" in the journal Reviews of Modern Physics, his lengthy article focused on the 'Lagrangian' function for a particle, a particular combination of kinetic and potential energy familiar from classical mechanics. The probability that a quantum object would travel from one location, x1, at a time t1, to some other location, x2, at a later time t2, Feynman showed, could be calculated by summing over-that is, integrating-all of the possible paths through space and time that connected these two end points. The contribution of each path to the total would be weighted by its classical Lagrangian function evaluated along that path" hence, the technique became known as path integrals. The main difference from the standard formalism lay not in outcomes, but in conceptual approach. Werner Heisenberg and Niels Bohr had argued vehemently during the 1920s that quantum mechanics spelled the end for any type of visualization of the atomic domain. Feynman countered with an intuitive approach, built around picturing the paths of particles through space and time. His greatest success [with his Feynman-diagrams] came on the heels of this path-integral approach" (DSB)."Feynman's two papers on QED [the two present papers] were completed in April and May 1949. In the first one, 'The Theory of Positrons,' he carefully explains the meaning of his diagrams beginning with their application to the Schrödinger equation. Application to the Dirac equation yields an interpretation of the positron in which Dirac's original hole theory is no longer needed. The second paper, 'Space-Time Approach to Quantum Electrodynamics,' contains the Feynman rules and explains their usage. By these rules, computations for specific problems are simplified so much that Schwinger, much later, said: "Like the silicon chip of more recent years, the Feynman diagram was bringing computation to the masses" (Brandt, Harvest of a Century).Dean Everett Wooldridge (1913 - 2006) was a prominent engineer in the aerospace industry. …

Feynman, Richard (1918-88) (1) The development of the space-time view of quantum electrodynamics. Offprint from Physics Today 19 (1966). [11]pp. Light creasing. (2) Typed letter to Eliane Jobredeaux on California Institute of Technology letterhead, signed "R. P. Feynman" in a secretarial hand, with envelope. 1 sheet. Pasadena, CA, 12 February 1981. 270 x 218 mm. Light creasing, faint rust-mark from paperclip. Together 2 items. Very good. The rare offprint of Feyman's Nobel lecture presented by Feynman 15 years after he received the Nobel Prize. This is the first instance that we can recall in which an offprint by Feynman is accompanied by his original presentation letter. Also, we learn from this letter than Feynman used a secretary to send and sign letters like this which presumably he dictated. Another detail evident from this letter is that Feynman retained copies of this offprint as many as 15 years after it was published. His letter reads, "The enclosed reprint describes the development of my experiment. Sincerely, R. P. Feynman." Feynman enclosed a reprint of his entertaining Nobel lecture, which departed from usual practice in presenting an informal anecdotal account of his discovery, rather than a rigorously scientific presentation which he feared might bore his listeners.
