Product Description
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 new introduction places both Feynman's book and his seminal contribution to QED in historical context and further highlights Feynman's uniquely appealing and illuminating style.

 College Physics came racing back to me full-speed. Fascinating read! October 12, 2008
I didn't know exactly what to expect, but bought this based on suggestions from a blog. It is actually a transcript of a series of lectures from Feynman and not specifically a book, per se.
That may be a good thing though, as a lecture is probably a little lighter reading and this is heady stuff.
Quite a bit of the beginning of the book is introductions and anecdotal stories about the various pop-physicists. Once you get into the actual lectures, you jump right into light as a wave vs a particle and it goes straight into the building blocks of the universe and what understand (and don't understand) about them.
The nice thing is that this is intended for the educated reader, but not for the PhD-in-Atomic-Physics reader. So if you have a basic grasp of physics, you will likely be able to follow this book.
If you hated science, this won't magically open the world of particle physics to you.
My only real complaint about the book is the location of the diagrams. Often the text will be talking about something that is two pages away in the diagrams and I found myself looking at the wrong diagram and being confused, or having to flip back and forth between a couple of pages to find the correct diagram once I figured out what was going on. This is distracting and un-necessary.
Overall, highly recommended as a challenging read for anyone who has an interest in physics and the building blocks of our universe and a desire to stretch their brain-muscles a little bit once again.
 A Fantastic Theory September 10, 2008

Even though these lectures are more than 20 years old, Feynman did an incredible job of explaining a fundamental concept in Physics. I can see now why he received the Nobel prize for his work in this area. I would call him the Carl Sagan of Physics, except that Mr. Sagan's popularity came later in time. QED is so bizarre and incredible, yet so accurate and powerful a theory that it boggles the mind! Mr. Feynman's explanation is so complete and articulate that anyone can understand it. This theory explains the physical underpinnings of most of our daily experience, the interactions of photons with matter, yet it is a complete surprise!
Highly comprehensible July 20, 2008

This book covers four lectures that explains QED in terms of the path integral method, which was developed by the author. Needless to say, this is authoritative on this approach, but it also remarkably clear and comprehensible. Notwithstanding that, I would recommend slow and careful reading, as you may find a small sequence of statements that seem perhaps a little unjustified. Later, Feynman fronts up to some of these, and explains why he oversimplified to get things going. If you see them first, and this is not unreasonable, I believe you will get more from the text. The first lecture is a general introduction that shows how the path of the photon as a particle can be followed in terms of time-of-flight from all possible paths. The assertion is, the photon is a particle, not a wave, however there is no explanation for why there is a term that I would call the phase. The second lecture is a tour-de force and explains in terms of this particle treatment, why light reflects and diffracts, and is particularly interesting in why light behaves as if it is reflected only from the front and back of glass, whereas it is actually scattered by electrons throughout the glass. The third lecture covers electron-photon interactions, and covers Feynman diagrams and shows why QED is the most accurate theory ever proposed. The fourth lecture may seem a bit of a disappointment. The author tries to cover a very wide range of phenomena, which he terms "loose ends", and in some ways this chapter has been overtaken somewhat, nevertheless it also gives a look into Feynman's mind, and that also is well worth the price of the book. It is also here that the issue of renormalization is discussed - if you could call Feynman admitting it is "a dippy procedure" a discussion.
Why buy the book? I suspect this is probably the best chance a non-specialist has of understanding the basis of QED. The biggest disappointment? Feynman dismisses wave theory, which everybody else uses, and replaces it with a monumental raft of integrals. My initial thoughts were that waves are effectively an analogue way of solving those integrals, perhaps a gift from nature, and it is a pity I can't ask Feynman why that option was dismissed.
Clearest intro to QED June 16, 2008
I have given this book to several very talented HS students. It can be understood even without higher math.
a little tough to read, but pretty good January 9, 2008

It takes some slogging, but this is pretty good. If you don't have a lot of physics background, you'll need patience, but your patience will be rewarded.
