QED: The Strange Theory of Light and Matter
Famous the world over for the creative brilliance of his insights into the physical world, Nobel Prize-winning physicist Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the nonscientist. QED--the edited version of four lectures on quantum electrodynamics that Feynman gave to the general public at UCLA as part of the Alix G. Mautn ...more

I love this area of physics and I think it’s wonderful: it is called quantum electrodynamics, or QED for short.
I love this book and I think it’s wonderful: it is called QED: The Strange Theory of Light and Matter, or QED for short.
I feel as though I’ve been searching for this book for a long time, and now I’ve finally found it. In scarcely 150 pages, Feynman takes you inside the logic of this famously obscure subject. What was before unintelligible is breezy in Feynman’s hands. What had befor ...more
(Any excuse for a Breaking Bad reference.)
Seriously, though, this is one of the best pop science books I’ve yet encountered. I read Surely You're Joking, Mr. Feynman!: Adventures of a Curious Character last year, and was thoroughly impressed by Feynman’s animated personality and his passion for physics. Now I find myself even more impressed by his exceptional teaching ability. QED: The Strange Theory of Light and Matter is a collection of 4 lectures he gave t ...more
I took this photo when I was about half way through the book. It shows a picture of a CD [click to enlarge]. It's been illuminated by an ordinary office lamp and the flashlight from my camera. I knew about this "rainbow" effect for a long time, but I didn't know exactly how it is created. This book gives some answers.
To write a successful book like QED (short for Quantum Electro-Dynamics) two prerequisites are required: 1) The author must know a great deal about the subject matter, and 2) He mu ...more
The theory of QED is fascinating, both in its explanatory power and its elegance. Using only a handful of ...more
Ce livre propose de vulgariser la théorie scientifique la plus exacte dont nous disposons avec laquelle il est possible de modéliser la lumière, la matière et leurs interactions réciproques, à savoir la mécanique quantique. Développée au cours du siècle précédent, elle se fonde sur des principes qui brusquent le sens commun, comme la dualité onde-corpuscule ou le principe de superposition, car il n'est plus possible de s'aider d'analogies à partir de notre expérience pour en rendre compte sans p ...more
He uses arrows to represent complex numbers in complex plane,with its modules and phases and uses sums and products of histories in the propagation of the photon ...more
Feynman uses light’s refraction to illustrate the relationship between electrons and photons. To under ...more
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. Este libro surge de una serie de cuatro conferencias que dio Feynman en UCLA (que en inglés no se dice ucla sino u-c-l-a, iusielei, dato CPI para viajeros por tierras californianas).
Feynman is confident and flamboyant in his style, which is easy and enjoyable to read. He also seems exceptionally able to put himself into the mind of a non-expert and explain things appropriately.
The book is based on 4 lectures explaining some ...more
Feynman explains quantum electrodynamics very clearly with a humorous twist. The book is logical and very well written altogether. The last chapter is the only somewhat hard part, since in that one Feyn ...more
I feel like I really understood something... maybe that's because I'm a physicist and I know some of these things, but nevertheless I think Feynman explained everything so clearly that a layman could ...more
I had encountered with quantum physics several times in previous books and every writer talking about how hard it is, and it turned out that they are absolutely right. I know that because I read the book very slowly and later on I even skipped some parts of the book.
Nature is simple and very perplexing at the same time; And as Feynman said "You see my physics students don't understand it... Tha ...more
Alas, that's the nature of science popularization. If you omit math, the heart is gone, and you have to make do with the leftover shell. Feynman does the best job of leaving behind some substance that I've ever seen in such a book.
Excellent pedagogy, and some great q ...more
