"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. In this quirky, fascinating book, he explains to laymen the quantum theory of light."" ― New Yorker
"Praise for Princeton's original edition:"[A]nother tour de force by the acknowledged master of clear explanation in physics.""---John Roche, Times Literary Supplement

"Praise for Princeton's original edition: "In four conversational and breezy chapters. . . . 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

Feynman explains how to do all the phase and related calculations using geometry (little arrows). I can’t say if that is enough if you don’t have some clue what is really happening. If you have a math/engineering background, it’s pretty easy to see this is just complex addition and multiplication on objects of the form exp(it) where i is the square root of -1. The way he explains this is itself as fascinating as the actual content.
If you are impressed with Feyman’s approach, you might like Lakoff’s book “Where Mathematics Comes From”. He makes an amazing argument that essentially all math is just a clever series of imagination tricks using our ability to count, measure, and imagine rotating things in our heads.
BTW, I personally don't have any great difficulty with a probabilistic view of quantum particles. I'm a little mystified why this idea of reality as probabilistic is objectionable to many physicists (including apparently Einstein). Perhaps this reflects my own ignorance, but for now, I don't find it objectionable. On the contrary, it seems wonderful to me that quantum particles are probabilistic. I would be troubled if the probabilities cannot be calculated or predicted, but (as far as I understand it) this is not the case. In fact, it's amazing that physicists can calculate the probabilities with such precision.
That being said, it spends a lot of time talking about HOW calculations are made and not really the physics behind them.
I liked the book. But. I think I’ll try and watch the lectures on YouTube as well.
Hearing him speak, and draw the diagrams in real-time will probably make it easier to consume.
Top reviews from other countries
I am now drawn by the chemistry that QED and I have sparked, asking how many protons, neutrons, and electrons does it take to tango with a quark? Mr. Feynman, I have received one of the many Photons you've emitted, and the insertion of thoughts at the speed of light, charges my electrons to emit delight.
This book will give you even more insights, if you know mathematics good enough to know what complex numbers are. But that's definitely not required.
