Sometimes, it's too late, but that makes you do it better. You probably imagine that this book is a physics text. Well, it is, but that that's not what it really is. Really, it's a love letter to a dead woman. Feynman says in his introduction that his friend Alix Mautner had always wanted him to explain quantum electrodynamics to her so that she could understand it, and he'd never gotten around to doing that. Now it was too late. But, somehow, you can see that that only made him want to do it, n..more

Richard Feynman's friend Alix had asked him to explain Quantum Electrodynamics (the titular QED) to her in a way a layman could understand many times. Heartbreakingly, it wasn't until her death that he actually found the time to write a series of four lectures that would do just that.

QED: The Strange Theory of Light and Matter is an outstanding book on a subject that is often overlooked or glossed-over in many popular physics books. Feynman does a deep dive on Quantum Electrodynamics: a theory that deals not only with the various interactions between light and matter, but which can be applied to every area of physics with the exception of gravitation and nuclear physics.
The theory of QED is fascinating, both in its explanatory power and its elegance. Using only a handful of..more

I've never seen something like this before! It explains the way quantum electrodynamics actually works (not just analogies), but without assuming any physics or math background. I would have been skeptical if the author were anyone other than Richard Feynman, but it's super well done. With my limited physics background, I found the explanations super clear, at least in the beginning.

Throughout the years of reading both popular and less-popular science, I’ve kind of steered clear of Richard Feynman. The main reason is that what others describe as a “larger than life persona” I tend to describe as really bloody annoying, what with his bongos and womanizing and oh-so-clever quips where he always gets the upper hand with the old and rusty physics establishment. Having now fought my way through QED, I can see that this may have been a mistake. My annoyance with his autobiographi..more

It's all arrows, man. All about arrows. Physics is not a subject I have a terribly good grasp on mainly because my eyes glaze over at the sight of advanced mathematical equations, however Feynman is a pretty great at making the complex subjects of particle physics and quantum mechanics intelligible to the layest of laypersons. Fortunately I also read this with able-minded people who translated the math into clearer ideas which of course opened things up to broader philosophical speculation--some..more

The intellectual feat that was performed by this man in creating a workable mathematics for the physics behind the way that light travels, and reflects is truly amazing.

I remember reading this book as a physics undergrad and not quite getting it. I get more of it and have a better understanding of why parts of it are hard to get. Feynman does a great job with his deceptively simple book on something that defies our common sense.

In this series of short lectures, Feynman reduces (except for gravity and radioactivity) the whole of the universe to quantum electrodynamics or QED.* QED involves the relationship between photons (light) and electrons (matter), or quantum phenomena, the interaction of which (electrons emit/give up and absorb/get photons/particles of light) creates all of the atoms and elements in the universe.

I think this is my favorite science book. This was in large part due to having Feynman's real voice in my head, as I've heard him often in recorded lectures and documentaries.
The book is transcription of a few lectures Feynman gave on Quantum Electrodynamics (QED), a branch of quantum theory he and Dirac developed. Feynman introduces a few simple rules on how electrons and photons behave (which appear to be easy-to-digest analogs for vector calculus) and then off he goes, explaining the theory a..more

Esta es una de las muchas incursiones que hizo el gran Feynman en el terreno de la divulgación científica. En realidad él no escribió ninguno de sus libros de divulgación científica, sino que se adaptaron de sus ciclos de conferencias de divulgación, que, ahí sí, Feynman preparaba a conciencia.

“What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school.. It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it.. That is because I don't understand it. Nobody does.”
“There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to 0.08542455. (My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the 'hand of God' wrote that number, and 'we don't know how He pushed his pencil.' We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!” More quotes…
