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>
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。
評分一本很薄的書,慕名費曼買瞭電子版,真的是…一頁一塊錢…也很值…
評分幾年後重讀。營養豐富的甜點。不僅是QED的圖景和概念,還是物理的範式和文化 - 哪裏需要問為什麼,哪裏不需要,怎麼問,問什麼。重新理解費曼。
評分simple and elegant
評分很好吃~!
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。
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...
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...
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!
