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. Feynman's bestselling introduction to the mind-blowing physics of QED—presented with humor, not mathematicsCelebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the public. In this extraordinary book, Feynman provides a lively and accessible introduction to QED, or quantum electrodynamics, an area of quantum field theory that describes 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 the substance and spirit of QED to the nonscientist.With an incisive introduction by A. Zee that places Feynman's contribution to QED in historical context and highlights Feynman's uniquely appealing and illuminating style, this Princeton Science Library edition of QED makes Feynman's legendary talks on quantum electrodynamics available to a new generation of readers. Provides An Introduction To Qed (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, The Author Communicates Both The Substance And Spirit Of Qed To The Layperson.
