Qed

"Physics Nobelist Feynman simply cannot help being original. In this quirky, fascinating book, he explains to laymen the quantum theory of light, a theory to which he made decisive contributions."--The New Yorker "Feynman's lectures must have been marvelous and they have been turned into an equally entrancing book, a vivid introduction to QED which is leavened and enlivened by his wit. Anyone with a curiosity about physics today should buy it, not only to get to grips with the deepest meaning of quantum theory but to possess a slice of history."--Pedro Waloschek, Nature Praise for Princeton's original edition: "Feynman simply cannot help being original.

Feynman, who himself gave the theory its most useful and powerful form, undertakes without one equation to explain QED to the generality of readers."--Philip Morrison, Scientific American "Using clear language, many visuals, and his own Feynman diagrams, the author presents a clear introduction to the quantum theory of the inter-action of light with matter, without mathematics but with humor."--Physics Teacher
