Physics, rather than mathematics, is the focus in this classic graduate lecture note volume on statistical mechanics and the physics of condensed matter. This book provides a concise introduction to basic concepts and a clear presentation of difficult topics, while challenging the student to reflect upon as yet unanswered questions.

This text material constitutes notes on the third of a three-semester course in quantum mechanics given at the California Institute of Technology in 1953, presenting the main results and calculational procedures of quantum electrodynamics.

In these classic lectures, Feynman analyses the theoretical questions related to electron and photon interactions at high energies. These lectures are based on a special topics course taught by Feynman at Caltech in 1971 and 1972. The material is dealt with on an advanced level and includes discussions of vector meson dominance and deep inelastic scattering. The possible consequences of the parton model are also analyzed.

When, in 1984?86, Richard P. Feynman gave his famous course on computation at the California Institute of Technology, he asked Tony Hey to adapt his lecture notes into a book. Although led by Feynman, the course also featured, as occasional guest speakers, some of the most brilliant men in science at that time, including Marvin Minsky, Charles Bennett, and John Hopfield. Although the lectures are now thirteen years old, most of the material is timeless and presents a ?Feynmanesque? overview of many standard and some not-so-standard topics in computer science such as reversible logic gates and quantum computers.

Like the "funny, brilliant, bawdy" (The New Yorker) "Surely You're Joking, Mr. Feynman!" this book's many stories-some funny, others intensely moving-display Richard P. Feynman's unquenchable thirst for adventure and unparalleled ability to recount important moments from his life. Here we meet Feynman's first wife, Arlene, who taught him of love's irreducible mystery as she lay dying in a hospital bed while he worked on the atomic bomb at nearby Los Alamos. We listen to the fascinating narrative of the investigation into the space shuttle Challenger's explosion in 1986 and relive the moment when Feynman revealed the disaster's cause through an elegant experiment: dropping a ring of rubber into a glass of cold water and pulling it out, misshapen. In "What Do You Care What Other People Think?" one of the greatest physicists of the twentieth century lets us see the man behind the genius.

"Some people say, 'How can you live without knowing?' I do not know what they mean. I always live without knowing. That is easy. How you get to know is what I want to know."--Richard P. Feynman Nobel Prize-winning physicist Richard P. Feynman (1918-88) was that rarest of creatures--a towering scientific genius who could make himself understood by anyone and who became as famous for the wit and wisdom of his popular lectures and writings as for his fundamental contributions to science. The Quotable Feynman is a treasure-trove of this revered and beloved scientist's most profound, provocative, humorous, and memorable quotations on a wide range of subjects. Carefully selected by Richard Feynman's daughter, Michelle Feynman, from his spoken and written legacy, including interviews, lectures, letters, articles, and books, the quotations are arranged under two dozen topics--from art, childhood, discovery, family, imagination, and humor to mathematics, politics, science, religion, and uncertainty. These brief passages--about 500 in all--vividly demonstrate Feynman's astonishing yet playful intelligence, and his almost constitutional inability to be anything other than unconventional, engaging, and inspiring. The result is a unique, illuminating, and enjoyable portrait of Feynman's life and thought that will be cherished by his fans at the same time that it provides an ideal introduction to Feynman for readers new to this intriguing and important thinker. The book features a foreword in which physicist Brian Cox pays tribute to Feynman and describes how his words reveal his particular genius, a piece in which cellist Yo-Yo Ma shares his memories of Feynman and reflects on his enduring appeal, and a personal preface by Michelle Feynman. It also includes some previously unpublished quotations, a chronology of Richard Feynman's life, some twenty photos of Feynman, and a section of memorable quotations about Feynman from other notable figures. Features: * Approximately 500 quotations, some of them previously unpublished, arranged by topic* A foreword by Brian Cox, reflections by Yo-Yo Ma, and a preface by Michelle Feynman* A chronology of Feynman's life* Some twenty photos of Feynman* A section of quotations about Feynman from other notable figures Some notable quotations of Richard P. Feynman: *"The thing that doesn't fit is the most interesting."*"Thinking is nothing but talking to yourself inside."*"It is wonderful if you can find something you love to do in your youth which is big enough to sustain your interest through all your adult life. Because, whatever it is, if you do it well enough (and you will, if you truly love it), people will pay you to do what you want to do anyway."*"I'd hate to die twice. It's so boring."

WITH A NEW INTRODUCTION BY BILL GATES In this warm, insightful portrait of the Winner of the Nobel Prize for Physics in 1965, we see the wisdom, humour and curiosity of Richard Feynman through a series of conversations with his friend Ralph Leighton. Winner of the Nobel Prize for Physics in 1965, Richard Feynman was one of the world's greatest theoretical physicists, but he was also a man who fell, often jumped, into adventure. An artist, safecracker, practical joker and storyteller, Feynman's life was a series of combustible combinations made possible by his unique mixture of high intelligence, unquenchable curiosity and eternal scepticism. Over a period of years, Feynman's conversations with his friend Ralph Leighton were first taped and then set down as they appear here, little changed from their spoken form, giving a wise, funny, passionate and totally honest self-portrait of one of the greatest men of our age.

Richard P. Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. In this lively work that "can shatter the stereotype of the stuffy scientist" (Detroit Free Press), Feynman recounts his experiences trading ideas on atomic physics with Einstein and cracking the uncrackable safes guarding the most deeply held nuclear secrets-and much more of an eyebrow-raising nature. In his stories, Feynman's life shines through in all its eccentric glory-a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.

From astrophysics to condensed matter theory, nearly all of modern physics employs the path integral technique. In this presentation, the developer of path integrals and one of the best-known scientists of all time, Nobel Prize-winning physicist Richard P. Feynman, presents unique insights into this method and its applications. Avoiding dense, complicated descriptions, Feynman articulates his celebrated theory in a clear, concise manner, maintaining a perfect balance between mathematics and physics.
This emended edition of the original 1965 publication corrects hundreds of typographical errors and recasts many equations for clearer comprehension. It retains the original's verve and spirit, and it is approved and endorsed by the Feynman family. The opening chapters explore the fundamental concepts of quantum mechanics and introduce path integrals. Subsequent chapters cover more advanced topics, including the perturbation method, quantum electrodynamics, and the relation of path integrals to statistical mechanics. In addition to its merit as a text for graduate courses in physics, this volume serves as an excellent resource for professionals.

What Do You Care What Other People Think? Further Adventures of a Curious Character is a captivating collection of reminiscences from freewheeling scientific genius Richard P. Feynman. Richard Feynman - Nobel Laureate, teacher and iconic intellect - possessed an unquenchable thirst for an adventure and an unparalleled gift for telling the extraordinary stories of his life. In this collection of short pieces Feynman describes everything from his love of beauty to college pranks to how his father taught him to think. He takes us behind the scenes of the space shuttle Challenger investigation, where he dramatically revealed the cause of the disaster with a simple experiment. And he tells us of how he met his beloved first wife Arlene, and their brief time together before her death. Sometimes intensely moving, sometimes funny, these writings are infused with Feynman's curiosity and passion for life. 'Feynman's voice echoes raw and direct through these pages' The New York Times 'Outrageously gifted, iconoclastic, irrepressible ... Richard Feynman still has the capacity to suprise' Observer 'One of the greatest minds of the twentieth century ... he was also stubborn, irreverent, playful, intensely curious and highly original in practically everything he did' New York Review of Books 'If more scientists were like Feynman, the world really would be a better, and better understood, place' Independent on Sunday Richard P. Feynman (1918-1988) was one of this century's most brilliant theoretical physicists and original thinkers. Feynman's other books, also available in Penguin, include QED, Six Easy Pieces, Six Not-so-Easy Pieces, Don't You Have Time to Think, The Pleasure of Finding Things Out, What Do You Care What Other People Think? and The Meaning of it All.

Winner of the Nobel Prize for Physics in 1965, Richard Feynman was also a man who fell, often jumped, into adventure - as artist, safe-cracker, practical joker and storyteller. This self-portrait has been compiled from taped conversations with his friend Ralph Leighton.

Quantum electrodynamics - or QED for short - is the 'strange theory' that explains how light and electrons interact. Thanks to Richard Feynman, it is also one of the rare parts of physics that is known for sure. In this lucid set of lectures, Feynman provides the definitive introduction to QED.

In these classic lectures, Feynman analyses the theoretical questions related to electron and photon interactions at high energies. These lectures are based on a special topics course taught by Feynman at Caltech in 1971 and 1972. The material is dealt with on an advanced level and includes discussions of vector meson dominance and deep inelastic scattering. The possible consequences of the parton model are also analyzed.

This classic work presents the main results and calculational procedures of quantum electrodynamics in a simple and straightforward way. Designed for the student of experimental physics who does not intend to take more advanced graduate courses in theoretical physics, the material consists of notes on the third of a three-semester course given at the California Institute of Technology.

Developing a theory that seamlessly combines relativity and quantum mechanics, the most important conceptual breakthroughs in twentieth century physics, has proved to be a difficult and ongoing challenge. This book details how two distinguished physicists and Nobel laureates have explored this theme in two lectures given in Cambridge, England, in 1986 to commemorate the famous British physicist Paul Dirac. Given for nonspecialists and undergraduates, the talks transcribed in Elementary Particles and the Laws of Physics focus on the fundamental problems of physics and the present state of our knowledge. Professor Feynman examines the nature of antiparticles, and in particular the relationship between quantum spin and statistics. Professor Weinberg speculates on how Einstein's theory of gravitation might be reconciled with quantum theory in the final law of physics. Highly accessible, deeply thought provoking, this book will appeal to all those interested in the development of modern physics.

Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely, quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's introduction places Feynman's book and his seminal contribution to QED in historical context and further highlights Feynman's uniquely appealing and illuminating style.

A series of classic lectures, delivered in 1960 and recorded for the BBC. This is Feynman's unique take on the problems and puzzles that lie at the heart of physical theory - with Newton's Law of Gravitation; on whether time can ever go backwards; on maths as the supreme language of nature.

This collection demonstrates Feynman's knack of finding the right everyday illustration to bring out the essence of a complicated principle - for example, the brilliant analogy between the law of conservation energy and the problem of drying yourself with wet towels.

Don't You Have Time to Think? collects the witty, eccentric and moving letters letters of Nobel Prize-winning physicist Richard P. Feynman. Richard Feynman was no ordinary genius. Brilliant, free-spirited and irreverent, he upset those in authority, gave captivating lectures, wrote equations on napkins in strip joints and touched countless lives everywhere. He also wrote hundreds of letters to friends, family, critics, colleagues and devoted fans around the world. Now these letters have been brought together for the first time. From down-to-earth advice to eager students to discussions of time travel and the atom bomb, and from blunt rebuttals to journalists to poignant exchanges with his first wife as she lay dying, they will introduce you to a unique person whose wisdom and lust for life inspired all those who came into his orbit. 'Nobel-winning physicist, expert bongo-player, safe-cracker and all-round genius, Feynman was, as this wonderful and inspiring collection records, also a champion letter-writer ... Witty, deadpan, warm ... some are unbearably poignant' Guardian 'Plain-speaking ... touching' Daily Telegraph 'He sparked excitement not just about science but also about the power of creativity, passion, curiosity' The New York Times Richard P. Feynman (1918-1988) was one of this century's most brilliant theoretical physicists and original thinkers. Feynman's other books, also available in Penguin, include QED, Six Easy Pieces, Six Not-so-Easy Pieces, Don't You Have Time to Think, The Pleasure of Finding Things Out, What Do You Care What Other People Think? and The Meaning of it All.

With a unique combination of dazzling intellect and touching simplicity, Feynman had a passion for physics that was merely the Nobel Prize-winning part of an immense love of life and everything it could offer. He was hugely irreverent and always completely honest with himself, with his colleagues, and with nature. No Ordinary Genius traces Feynman's remarkable adventures inside and outside science, in words and more than one-hundred photographs, many of them supplied by his family and close friends. The words are often his own and those of family, friends, and colleagues such as his sister, Joan Feynman; his children, Carl and Michelle; Freeman Dyson; Hans Bethe; Daniel Hillis; Marvin Minsky; and John Archibald Wheeler. The book gives vivid insight into the mind of a great creative scientist at work and at play, and it challenges the popular myth of the scientist as a cold reductionist dedicated to stripping romance and mystery from the natural world. Feynman's wonderfully infectious enthusiasm shines through in his photographs and in his tales."
