Read QED: The Strange Theory of Light and Matter Online Free - 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. Mautner Memorial Lecture series--is perhaps the best example of his ability to communicate both the substance and the spirit of science to the layperson.
The focus, as the title suggests, is quantum electrodynamics (QED), the part of the quantum theory of fields that describes the interactions of the quanta of the electromagnetic field-light, X rays, gamma rays--with matter and those of charged particles with one another. By extending the formalism developed by Dirac in 1933, which related quantum and classical descriptions of the motion of particles, Feynman revolutionized the quantum mechanical understanding of the nature of particles and waves. And, by incorporating his own readily visualizable formulation of quantum mechanics, Feynman created a diagrammatic version of QED that made calculations much simpler and also provided visual insights into the mechanisms of quantum electrodynamic processes.
In this book, using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman successfully provides a definitive introduction to QED for a lay readership without any distortion of the basic science. Characterized by Feynman's famously original clarity and humor, this popular book on QED has not been equaled since its publication.

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...

I love this area of physics and I think it’s wonderful: it is called quantum electrodynamics, or QED for short.

My reaction upon finishing this book:
(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 anima...

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 b...

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. This book i...

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 whi...

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...

Wonderful,Feynman is a genius of popularization,without a mathematical expression has achieved the goal of give the rigurous quantum electrodinamics fundaments of geometric and physical optics,is to say,refraction,refraction index,reflexion, difraction ,converging lenses,classic Fermats principle...

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 intelligib...

The particle view of physics and how Richard Feynman was able to explain all of the weird ways that light behaves was a thoroughly engrossing read. The intellectual feat that was performed by this man in creating a workable mathematics for the physics behind the way that light travels, and reflec...
