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>
By the way, what I have just outlined is what I call a "physicist's history of physics," which is never correct. What I am telling you is a sort of conventionalized myth-story that the physicists tell to their students, and those students tell to their students, and is not necessarily related to the actual historical development, which I do not really know!

#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）

一本很薄的书，慕名费曼买了电子版，真的是…一页一块钱…也很值…

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。

本人收获最大的量子力学读物

几年后重读。营养丰富的甜点。不仅是QED的图景和概念，还是物理的范式和文化 - 哪里需要问为什么，哪里不需要，怎么问，问什么。重新理解费曼。

6h科普讲座的文字版，浅出但不深入。读来可初步培养关于Feynman图和路径积分的物理直觉，但对理解QFT的无论是数学上还是物理上的技术难题都无甚益处。另外读下来给人的感觉好像quantum就是引入复数，对于如何理解观测的非交换性这点也语焉不详。总得来说还是差强人意，要是能穿越回去提问就好了。

费老师的课果然不会叫人失望🤣

强推！本书虽是为了给毫无物理基础的人科普艰深却成熟的量子电动力学理论，但却意外地使作为物理专业高年级学生的我受益匪浅！与现今泛滥的一味只求泛泛谈论物理理论有多么“神奇”科普影视作品相比，本书不仅涵盖了出版前五十年来的前沿的理论，而且也对推导过程娓娓道来。也就是说，这种好的科普，不是让受众认为一个艰深的理论有多么“玄妙”，相反是为了让人体验到其平实之处。本书从概率幅及态矢量的引入（比作停表），到路径... 强推！本书虽是为了给毫无物理基础的人科普艰深却成熟的量子电动力学理论，但却意外地使作为物理专业高年级学生的我受益匪浅！与现今泛滥的一味只求泛泛谈论物理理论有多么“神奇”科普影视作品相比，本书不仅涵盖了出版前五十年来的前沿的理论，而且也对推导过程娓娓道来。也就是说，这种好的科普，不是让受众认为一个艰深的理论有多么“玄妙”，相反是为了让人体验到其平实之处。本书从概率幅及态矢量的引入（比作停表），到路径积分的介绍，再到对反射及折射现象的量子电动力学的解释，直到最后将QED与QCD等理论进行对比，说明优秀的物理理论内在的相似性，都足以令人震慑！尤其值得说的，本书插入的大量费曼图，这给省去数学推导、提供直观物理视野提供了无与伦比的帮助。费曼一贯的幽默感，也是亮点所在！ (展开)
