  > 我得学多久物理才能彻底看懂这句话里的所有内容？直接去读 David J. Griffiths 的《Introduction to Electrodynamics》（电动力学导论）吧。写得非常棒的教材。唯一的问题可能是，如果你不懂向量微积分，可能就读不懂这本书，所以你还得学点向量微积分。然后开始读导论……

  > How long would I have to study physics to be able to understand everything in this sentence? Just start reading David J. Griffiths: Introduction to Electrodynamics. A very well written textbook. The problem might be, if you don't know vector calculus, you might not be able to read this book, so you need to learn some vector calculus, too. Then start reading Introduction…

  《Introduction to Quantum Mechanics》（量子力学导论）和《Introduction to Electrodynamics》（电动力学导论），都是 David J. Griffiths 写的。他还写了《Introduction to Elementary Particles》（基本粒子导论），不过我没读过那本。这两本书都堪称大师级，把极其复杂的领域拆解得通俗……

  Introduction of Quantum Mechanics and Introduction to Electrodynamics, both by David J. Griffiths. He also wrote Introduction to Elementary Particles, but I have not read that one. Both books masterfully take exceptionally complex fields and break them down into easily…

  ……只要遵守 ARRL 手册级别的经验法则就行了。但要真正理解与辐射和天线相关的电磁理论，你必须硬啃到 Griffiths 的《Introduction to Electrodynamics》最后几章。不过要想对天线建立直观认识、亲手制作天线或者跑建模软件，倒也没必要做到这一步。

  …to stick to the rules of thumb at the level of the ARRL handbooks. To understand the EM theory related to radiation and antennas, you really need to work through to the final chapters of Griffiths, "Introduction to Electrodynamics". But that is not necessary to get an intuitive understanding of antennas, to construct them, or to run the modeling software.

  话是这么说，不过挺好奇如果是研究生级别的电动力学，你会推荐哪本书？注意作者已经推荐本科先学 Griffiths 的《Introduction to Electrodynamics》了（在我看来读那本真是一种享受）。

  Well yes, but curious what book you would recommend instead for graduate electrodynamics? Note that she already recommends first studying Griffith's Introduction to Electrodynamics at the undergraduate level (and that one is a true pleasure to read imho).

  ……高阶牛顿力学——特别是拉格朗日和哈密顿力学。快结尾处还有一章讲混沌动力学。这方面的另一个选择是 Goldstein 的《Classical Mechanics》（经典力学）。8. Griffiths 的《Introduction to Electrodynamics》。比 Purcell 那本更进阶的电磁学。如果你还想更进一步，那随时可以看 Jackson 的《Classical Electrodynamics》（经典电动力学）。9. Shankar 的《Principles of Quantum Mechanics》（量子力学原理）。这本书花更多时间……

  …advanced Newtonian mechanics --- in particular Lagrangian and Hamiltonian dynamics. There is a chapter on chaotic dynamics towards the end, too. Another option here is Classical Mechanics by Goldstein. 8. Introduction to Electrodynamics by Griffiths. More advanced E&M than Purcell. If you want to go further, then there's always Classical Electrodynamics by Jackson. 9. Principles of Quantum Mechanics by Shankar. This spends more time…

  ……我英语课的书评报告选了它，因为我是个彻头彻尾的书呆子，而且觉得这是个挺好玩的项目。其他大部分人都挑了漫画书读，因为漫画居然也算“非虚构类”（真没开玩笑）。写得较好的教材之一是 David J. Griffiths 的《Introduction to Electrodynamics》。那本书一直让我印象深刻。

  …book report for English class, because I was a total nerd and it seemed like a fun project. Most others read a comic book because those passed as "non-fiction" (for real). One of the better textbooks is Introduction to Electrodynamics by David J. Griffiths. That one stands out in my mind.
