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.</p>
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.</p>
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.</p>

读后感
光不仅有粒子性，还有波动性，因此我们将之称为光子，光代表着她的波动性，子代表着她的粒子性。因此我们可以称之为奇异物质，奇异物质没有质量，没有体积只有动量及相关量。

评分 评分QED，量子电动力学，听这名字就装逼到了极致，并且对于大多数人来说，光看这个装逼的名字，肯定就望而却步了！ 只要是接触量子力学有关的书，那肯定免不了接触到QED这个名词，我也是出于好奇，就想买本书看看QED到底是个什么玩意。说到这东西，入门的话，肯定选择...

非常不故弄玄虚的小书，虽然是小书，有种在大学里学电的感觉，下定决心要好好听，只是走神了1分钟，突然就什么都不懂了。还好是书，可以不停地反复看。
评分#物理学家爱人养成术 怎么讲，就是字面上都看懂了然后其实又没看懂（到底它们的意义在哪里）
评分不是这个版本
