Celebrated for his brilliantly quirky insights into the physical world, Nobel la
ureate Richard Feynman also possessed an extraordinary talent for explaining dif
ficult concepts to the general public. Here Feynman provides a classic and defin
itive introduction to QED (namely, quantum electrodynamics), that part of quantu
m field theory describing the interactions of light with charged particles. Usin
g everyday language, spatial concepts, visualizations, and his renowned "Feynman
diagrams" instead of advanced mathematics, Feynman clearly and humorously commu
nicates both the substance and spirit of QED to the layperson. A. Zee's introduc
tion places Feynman's book and his seminal contribution to QED in historical con
text and further highlights Feynman's uniquely appealing and illuminating style.
