是的，这也是我最喜欢的费曼讲座之一，我正想提呢，它以文字形式重新收录在了《Six Not-So-Easy Pieces》的对称性章节里。（最初出自他厚重的《费曼物理学讲义》。）他先让你描述人体基本的外观解剖结构——这基本是对称的——然后开始讲内部结构，接着……
Yes, one of my favorite Feynman lectures I was going to comment on, it re-appears in written form in the symmetry chapter in "Six Not-So-Easy Pieces". (Originally from his massive Feynman Lectures on Physics.) He starts from after you've described the basic exterior human anatomy, which is mostly symmetrical, then he starts with the interior and…
……受到启发并进入那种思维状态。《费曼物理学讲义》：费曼在 MIT 给大一新生开的课程。内容非常丰富，够你看上好几年。《Six Easy Pieces》：来自费曼的 6 篇浅显讲座。《Six Not-So-Easy Pieces》：来自费曼的 6 篇没那么轻松的讲座。还有《费曼计算学讲义》。
…inspired and into the mindset. Feynman Lectures on Physics: freshman level course that Feynman taught at MIT. Lots of material, will last you year(s). Six easy pieces: 6 easy lectures from Feynman. Six not so easy pieces: 6 not-so-easy lectures from Feynman. Feynman lectures on computation.
……其实根本没教任何物理。我个人会向外行推荐费曼的书，比如《QED：光和物质的奇妙理论》（QED: The Strange Theory of Light and Matter）、《物理定律的本性》（The Character of Physical Law），或者《Six Easy Pieces》（接着读《Six Not So Easy Pieces》），这些能让人在没有科普营销辞藻干扰的情况下，至少接触一点物理。在我看来，哪怕这些书也有局限性，因为如果你不亲自去算那些数学，就无法真正理解物理，而且……
…actually teach any physics. I personally would recommend Feynman's books for the layman, such as QED: The Strange Theory of Light and Matter or The Character of Physical Law, or Six Easy Pieces (followed by Six Not So Easy Pieces), as ways for people to get at least some exposure to physics without popsci buzzwords. IMO even those books are limited, because you can't really understand physics without actually doing the math and…
楼主，咱俩同病相怜。我也深陷在量子力学的深坑里，刚读完《Six Easy Pieces》、《Six Not-So-Easy Pieces》和《QED》（强烈推荐），并且一直试着啃几本量子物理教科书。让我震惊的是，高质量的可视化内容居然这么少：YouTube 上稀稀拉拉的一些视频……
OP, we're in the same boat. I also am in a deep, deep QM hole, and just finished reading Six Easy Pieces, Six Not-So-Easy Pieces, and QED (HIGHLY recommended), and have been trying to work through several quantum physics textbooks. It's astonishing to me how few high-quality visualizations there are: smatterings of videos on youtube…
……理解它。但我有求知欲。所以对我来说，理解它的最佳途径是一条既能保持这种好奇心、又能不断有所斩获的道路。我可以重读《The Six (Not So ) Easy Pieces》，哪怕一点都看不懂，却依然觉得大有收获。我可以去摆弄阿诺德猫映射（Arnold's cat map），慢慢地，不带任何科学严谨性，仅凭这只裸猿的好奇心，去体会这些概念……
…understand it. But I have intellectual curiosity. So the best path forward for me understanding is a path that can maintain that curiosity while making progress on understanding. I can reread the The Six (Not So ) Easy Pieces and not understand any of it and still find value in it. I can play with Arnold's cat and, slowly, through no scientific rigor other than the curiosity of the naked ape, I can experience these concepts…
……试图让自己看起来比实际更有深度。这很像理查德·费曼的观点：如果你不能把一件事情用大一新生讲座的形式讲清楚，你就没有真正理解它。[1] [1]：费曼，《Six Not-So-Easy-Pieces: Einstein's Relativity, Symmetry, and Space-Time》
…attempting to appear more thoughtful than you are. It's a lot like the Richard Feynman idea that if you can't distill something to a freshman lecture, you don't really understand it.[1] [1]: Feynman, Six Not-So-Easy-Pieces: Einstein's Relativity, Symmetry, and Space-Time
