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>
具體描述
讀後感
想要了解什么是路径积分？害怕数学？那么这本书就绝对 是你的唯一选择了。 这是大师的一个科普讲座的演讲稿。由于其对象是对物理了解不多的人，所以没有使用数学，但是物理概念及其清晰。强力推荐！
評分开篇的某些内容会让人觉得：本来挺简单的，干嘛用这么复杂的方法阐述。但看到后来就会发现这种方法是贯穿始终的，越往后，问题越复杂，你会发现，用这种方法反而有助于理解，这就是“费曼式”的！
評分 評分高中數學物理水平就能讀懂的漂亮科普。 而且作者本人的風格也極具魅力。 太棒了，所以沒法說的更多。
評分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...

幽默的、智商過剩的物理學傢。
评分本人收獲最大的量子力學讀物
评分費曼講量子力學，很搞笑哈
评分本人收獲最大的量子力學讀物
评分神作。大師小書。給純外行的量子電動力學科普。精彩萬分地描述瞭一個拋開數學之後的量子電動力學究竟在乾什麼的故事。精妙絕倫，受益匪淺。
