#物理学家爱人养成术 怎么讲,就是字面上都看懂了然后其实又没看懂(到底它们的意义在哪里)
评分本人收获最大的量子力学读物

评分几年后重读。营养丰富的甜点。不仅是QED的图景和概念,还是物理的范式和文化 - 哪里需要问为什么,哪里不需要,怎么问,问什么。重新理解费曼。

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,即量子电动力学,是用量子论来解释电动力学的成熟理论。如此艰深的物理理论,天才的费曼在这本书中却能讲得人人都能看得懂。全书171页,共四个部分,每部分平均40多页。书中有大量的图解,是看懂这本书的重要组成部分。这本书同样是费曼的一个讲座的整理稿,因此读起来毫...

评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!
评分QED,讲述了光子的运动、电子的运动与光子 电子的相互作用。此外,最后一章讲述了QCD。 一开篇以部分反射为例,讲述了光子的运动特性。光以粒子的特性运动,运动规律不再遵循经典力学中,某一时刻位于某一位置的规律;而是以波函数表示的。费曼采用的小箭头运算的方法明晰表达...
