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." We are not aware of any other copy of this preliminary version of Feynman's lectures having appeared on the market, and we have located no institutional holdings other than Caltech. Richard Feynman a magician of the highest caliber'" (Biographical Memoirs of Fellows of the Royal Society of London 48 (2002), p. the working of their minds is for all intents and purposes incomprehensible. Once we understand what he has done, we feel certain that we, too, could have done it. There is no mystery as to how his mind works. An ordinary genius is a fellow that you and I would be just as good as, if we were only many times better.

"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'. Perhaps no other set of physics books has had such wide impact, for so long" (Kip Thorne). They have been studied worldwide by novices and mature physicists alike they have been translated into at least a dozen languages with more than 1.5 millions copies printed in the English language alone. "Feynman's lectures are as powerful today as when first published, thanks to Feynman's unique physics insights and pedagogy. Throughout the process we benefitted from the continual help and advice of Professor Feynman" (Sands). Sometimes we felt we should add some new material to improve the clarity or balance of the presentation. For others of the lectures a major reworking and rearrangement of the material was required. For some of the lectures this could be done by making only minor adjustments of the wording in the original transcript. "We hoped to make the written version as clear an exposition as possible of the ideas on which the original lectures were based. The printed lectures were not a verbatim transcript of what Feynman said, but were edited by Leighton and Sands. This section of the Feynman Lectures is a record of part of the second year's lectures, which were given to the sophomore class during the 1962-1963 academic year (all Caltech sophomores were required to take the class, regardless of their majors). No more than 300 copies of this pre-publication edition were printed. It is copyrighted 1963, one year before the first published edition of the Feynman lectures, produced by Addison-Wesley. According to the curators of Caltech's Feynman Lectures website (), this preliminary edition was produced by Caltech's graphics department between the end of the 1962-1963 academic year and the beginning of the 1963-64 academic year. Extremely rare pre-publication issue of a section of Feynman's legendary lectures on physics, namely that devoted to electromagnetism, from Maxwell's equations to the optical and magnetic properties of materials, and concluding with four lectures on elasticity and fluid flow.
