Background

By 1960,
Richard Feynman Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American theoretical physicist. He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of t ...

was concerned about the quality of the introductory courses for undergraduate students. It was thought the courses were burdened by an old-fashioned syllabus and the exciting discoveries of recent years, many of which had occurred at Caltech, were not being taught to the students. Thus, it was decided to reconfigure the first physics course offered to students at Caltech, with the goal being to generate more excitement in the students. Feynman readily agreed to give the course, though only once. Aware of the fact that this would be a historic event, Caltech recorded each lecture and took photographs of each drawing made on the blackboard by Feynman. Based on the lectures and the tape recordings, a team of physicists and graduate students put together a manuscript that would become ''The Feynman Lectures on Physics''. Although Feynman's most valuable technical contribution to the field of physics may have been in the field of quantum electrodynamics, the Feynman Lectures were destined to become his most widely-read work. ''The Feynman Lectures'' are considered to be one of the most sophisticated and comprehensive college-level introductions to physics. Feynman himself stated in his original preface that he was “pessimistic” with regard to his success in reaching all of his students. The Feynman lectures were written “to maintain the interest of very enthusiastic and rather smart students coming out of high schools and into Caltech”. Feynman was targeting the lectures to students who, “at the end of two years of our previous course,

very discouraged because there were really very few grand, new, modern ideas presented to them”. As a result, some physics students find the lectures more valuable after they have obtained a good grasp of physics by studying more traditional texts, and the books are sometimes seen as more helpful for teachers than for students. While the two-year course (1961–1963) was still underway, rumors of it spread throughout the physics research and teaching community. In a special preface to the 1989 edition,

Goodstein and Neugebauer also stated that, “it was eynman’speers — scientists, physicists, and professors — who would be the main beneficiaries of his magnificent achievement, which was nothing less than to see physics through the fresh and dynamic perspective of Richard Feynman”, and that his "gift was that he was an extraordinary teacher of teachers".

Abbreviated editions

Six readily-accessible chapters were later compiled into a book entitled ''Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher''. Six more chapters are in the book ''Six Not So Easy Pieces: Einstein's Relativity, Symmetry and Space-Time''. “''Six Easy Pieces'' grew out of the need to bring to as wide an audience as possible, a substantial yet nontechnical physics primer based on the science of Richard Feynman... General readers are fortunate that Feynman chose to present certain key topics in largely qualitative terms without formal mathematics…”Extract of page vii
