Born in 1918 in New York City, Richard P. Feynman received his Ph.D.
from Princeton in 1942. Despite his youth, he played an important part in the
Manhattan Project at Los Alamos during World War II. Subsequently, he taught
at Cornell and at the California Institute of Technology. In 1965 he received the
Nobel Prize in Physics, along with Sin-ltiro Tomonaga and Julian Schwinger, Íor
his work in quantum electrodynamics.
Dr. Feynman won his Nobel Prize for successfully resolving problems with the
theory oŸ quantum electrodynamics. He also created a mathematical theory that
accounts for the phenomenon of superfuidity ín liquid helium. Thereafter, with
Murray Gell-Mamn, he did fundamental work in the area of weak interactions such
as beta decay. In later years Feynman played a key role in the development of
quark theory by putting forward his parton model of high energy proton collision
DTOC©SSGS.
Beyond these achievements, Dr. Feynman introduced basic new computa-
tional techniques and notations into physics—above all, the ubiquitous Eeynman
diagrams that, perhaps more than any other formalism in recent scientifc history,
have changed the way in which basic physical processes are conceptualized and
calculated.
teynman was a remarkably efective educator. Of all his numerous awards,
he was especially proud of the Oersted Medal for Teaching, which he won In
1972. The Fewwman Lectures on Phụsics, originally published in 1963, were
described by a reviewer in Scientific American as “tough, but nourishing and full
of favor. After 25 years it is fhe guide for teachers and for the best of beginning
students.” In order to increase the understanding of physics among the lay public,
Dr. Feynman wrote The Character oƒ Phụsical[ Lau and QED: The Strange
Theor oƒ Light and Matter. He also authored a number of advanced publications
that have become classic references and textbooks for researchers and students.
Richard Feynman was a constructive publie man. His work on the Challenger
commission is well known, especially his famous demonstration of the susceptibility
of the O-rings to cold, an elegant experiment which required nothing more than
a glass of ice water and a C-clamp. Less well known were Dr. Feynman's eforts
on the California State Curriculum Committee in the 1960s, where he protested
the mediocrity of textbooks.

A recital of Richard Feynman's myriad scientific and educational accomplish-
ments cannot adequately capture the essence of the man. Âs any reader of
even his most technical publications knows, Feynman's lively and multi-sided
personality shines through all his work. Besides being a physicist, he was at
various times a repairer of radios, a picker of locks, an artist, a dancer, a bongo
player, and even a decipherer of Mayan Hieroglyphics. Perpetually curious about
his world, he was an exemplary empiricist.
Richard Feynman died on February 15, 1988, in Los Angeles.

Nearly fifty years have passed since Richard Eeynman taught the introductory
physics course at Caltech that gave rise to these three volumes, 7 he Fewman
Lectures on Phụsics. In those fñẨty years our understanding of the physical
world has changed greatly, but The Feynman Lectures on Phạs¿cs has endured.
teynman”s lectures are as powerful today as when frst published, thanks to
teynman”s unique physics insights and pedagogy. “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 prinwed in the
linglish language alone. Perhaps no other set of physics books has had such wide
Impact, for so long.
This Neu Miienmium Edition ushers in a new era for The Feunman Lectures
ơn Phụsics (FLP): the twenty-flrst century era of electronic publishing. LP
has been converted to eFP, with the text and equations expressed in the IATEX
electronic typesetting language, and all ñgures redone using modern drawing
SOftware.
The consequences for the przn# version of this edition are øœø‡ startling; it
looks almost the same as the original red books that physics students have known
and loved for decades. The main differences are an expanded and improved index,
the correction of 885 errata found by readers over the fve years since the frst
printing of the previous edition, and the ease of correcting errata that future
readers may fñnd. To this I shall return below.
The eBook Version of this edition, and the Enhanced blectronic Version are
electronic innovations. By contrast with most eBook versions of 20th century tech-
