''QED: The Strange Theory of Light and Matter'' is an adaptation for the general reader of four lectures on quantum electrodynamics (QED) by Richard Feynman (1918-1988). ''QED'' was designed to be a popular science book, written in a witty style, and containing just enough quantum-mechanical mathematics to allow the solving of very basic problems in quantum electrodynamics by an educated lay audience. It is unusual for a popular science book in the level of mathematical detail it goes into, actually allowing the reader to solve simple optics problems, as might be found in an actual textbook. But unlike in a typical textbook, the mathematics is taught in very simple terms, with no attempt to solve problems efficiently, use standard terminology, or facilitate further advancement in the field. The focus instead is on nurturing a basic conceptual understanding of what is really going on in such calculations. Complex numbers are taught, for instance, by asking the reader to imagine that there are tiny clocks attached to subatomic particles. The book was first published in 1985 by the Princeton University Press. ==The book== In an acknowledgement Feynman wrote:〔R. Feynman (1985, 2006) ''QED'', page xxv, Princeton University Press ISBN 978-0-691-12717-0 〕 :This book purports to be a record of the lectures on quantum electrodynamics I gave at UCLA, transcribed and edited by my good friend Ralph Leighton. Actually, the manuscript has undergone considerable modification. Mr. Leighton's experience in teaching and in writing was of considerable value in this attempt at presenting this central part of physics to a wider audience. Much of Feynman's discussion springs from an everyday phenomenon: the way any transparent sheet of glass partly reflects any light shining on it. Feynman also pays homage to Isaac Newton's struggles to come to terms with the nature of light. Feynman's lectures were originally given as the Sir Douglas Robb lectures at the University of Auckland, New Zealand in 1979. Videotapes of these lectures were made publicly available on a not-for-profit basis in 1996 and more recently have been placed online by the (Vega Science Trust ). The book is based on Feynman's delivery of the first Alix G. Mautner Memorial Lecture series for the general public at the University of California, Los Angeles (UCLA) in 1983. The differences between the book and the original Auckland lectures were discussed in June 1996 in the ''American Journal of Physics''. In 2006, Princeton University Press published a new edition with a new introduction by Anthony Zee. He introduces Feynman's peculiar take at explaining physics, and cites: "According to Feynman, to learn QED you have two choices: you can go through seven years of physics education or read this book". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「QED: The Strange Theory of Light and Matter」の詳細全文を読む スポンサード リンク
