圖書描述

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>

非常不故弄玄虛的小書，雖然是小書，有種在大學裏學電的感覺，下定決心要好好聽，隻是走神瞭1分鍾，突然就什麼都不懂瞭。還好是書，可以不停地反復看。

評分☆☆☆☆☆

費曼就是能把量子電動力學講到中學生都可以理解的程度。隻有真正懂的人能把現代物理理論錶達這麼清楚簡單。手起刀落，不故弄玄虛，太帥瞭。

#物理學傢愛人養成術怎麼講，就是字麵上都看懂瞭然後其實又沒看懂（到底它們的意義在哪裏）

強推！本書雖是為瞭給毫無物理基礎的人科普艱深卻成熟的量子電動力學理論，但卻意外地使作為物理專業高年級學生的我受益匪淺！與現今泛濫的一味隻求泛泛談論物理理論有多麼“神奇”科普影視作品相比，本書不僅涵蓋瞭齣版前五十年來的前沿的理論，而且也對推導過程娓娓道來。也就是說，這種好的科普，不是讓受眾認為一個艱深的理論有多麼“玄妙”，相反是為瞭讓人體驗到其平實之處。本書從概率幅及態矢量的引入（比作停錶），到路徑積分的介紹，再到對反射及摺射現象的量子電動力學的解釋，直到最後將QED與QCD等理論進行對比，說明優秀的物理理論內在的相似性，都足以令人震懾！尤其值得說的，本書插入的大量費曼圖，這給省去數學推導、提供直觀物理視野提供瞭無與倫比的幫助。費曼一貫的幽默感，也是亮點所在！
