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。
評分本人收獲最大的量子力學讀物
評分一共4個lecture。最後一個知識性強於概念性,就不好看瞭。前三個更好些。
評分很好吃~!
評分根據費曼自己的說法,想搞明白QED,要麼去讀7年的物理學課程,要麼看完這本書
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>
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...
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!
評分光不仅有粒子性,还有波动性,因此我们将之称为光子,光代表着她的波动性,子代表着她的粒子性。因此我们可以称之为奇异物质,奇异物质没有质量,没有体积只有动量及相关量。
