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>

讀後感
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...
評分QED的科普读物，并且由QED发明人之一；物理学家中的帅哥Feynman撰写，不可不读，曾经这是唯一一本专门讲QED科普书，现在我不知道还有没有其它的这类书，如果没有，这本书仍然是这个领域的唯一一本。 BTW。网上到处流传其英文版电子书，qiji也有中文版的。 据我所知，Feynman仅...

聽名字就會嚇一跳，有勇氣翻開的人就會覺得，哎吆，不錯喔！費曼花瞭四節課的時間介紹瞭量子電動力學中的一個計算模型，因為忽略掉具體計算技巧，可讀性較強。正因為如此，有好多精妙的地方就不是能夠很透徹的理解。

评分simple and elegant
评分一本很薄的書，慕名費曼買瞭電子版，真的是…一頁一塊錢…也很值…
