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>
一共4个lecture。最后一个知识性强于概念性,就不好看了。前三个更好些。
评分#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)
评分费曼就是能把量子电动力学讲到中学生都可以理解的程度。只有真正懂的人能把现代物理理论表达这么清楚简单。手起刀落,不故弄玄虚,太帅了。
评分不是这个版本
评分本人收获最大的量子力学读物
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。
评分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!
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!
评分我一直对相对论里,光速作为一种绝对的存在这个观念很着迷,我认为它指向了宇宙的终极秘密:为何所有的space-time都是相对的,而c却是超越时空的存在? 于是《QED—光和物质的奇妙理论》这书的标题一下子就把我抓住了。 基础的量子力学框架描述的是单个粒子如何运动。但要描述...
