具体描述
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
虽然作者是大大鼎鼎的费曼，但是不用数学还是苦了这位大师，对于我这样学了复数运算的人来说，这样做反而更难理解了。 如果你只是想被科普一下QED，可以看看。如果你是要上大学的，还是等到课堂上让老师用数学来讲述吧，费曼在这本书里并没有讲更多的东西。 真想体验费曼的伟...
评分 评分我一直对相对论里，光速作为一种绝对的存在这个观念很着迷，我认为它指向了宇宙的终极秘密：为何所有的space-time都是相对的，而c却是超越时空的存在？ 于是《QED—光和物质的奇妙理论》这书的标题一下子就把我抓住了。 基础的量子力学框架描述的是单个粒子如何运动。但要描述...

simple and elegant
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）
评分费曼就是能把量子电动力学讲到中学生都可以理解的程度。只有真正懂的人能把现代物理理论表达这么清楚简单。手起刀落，不故弄玄虚，太帅了。
评分一共4个lecture。最后一个知识性强于概念性，就不好看了。前三个更好些。
评分幽默的、智商过剩的物理学家。
