The focus, as the title suggests, is quantum electrodynamics (QED), the part of the quantum theory of fields that describes the interactions of the quanta of the electromagnetic field-light, X rays, gamma rays--with matter and those of charged particles with one another. By extending the formalism developed by Dirac in 1933, which related quantum and classical descriptions of the motion of particles, Feynman revolutionized the quantum mechanical understanding of the nature of particles and waves. And, by incorporating his own readily visualizable formulation of quantum mechanics, Feynman created a diagrammatic version of QED that made calculations much simpler and also provided visual insights into the mechanisms of quantum electrodynamic processes.
In this book, using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman successfully provides a definitive introduction to QED for a lay readership without any distortion of the basic science. Characterized by Feynman's famously original clarity and humor, this popular book on QED has not been equaled since its publication. less

Marcus Chown When Feynman was at Cal Tech, this wealthy couple who’d grown up in the same New York neighbourhood as he had said, Look, you’ve won this Nobel Prize, now explain to ordinary people what for. And Feynman said, No, it’s too complicated. But eventually he did this series of public lectures, and that was the book. It’s a tiny book and in it he describes the whole of quantum electrodynamics without a single equation. (Source)
