The Feynman Lectures on Gravitation 源自理查德·费曼在 1962–1963 学年于加州理工学院讲授引力物理学课程时所整理的讲义。在开设这些课程之前的数年间，费曼曾对引力物理学的基础问题进行过深入而长久的思考，但他发表的成果却极少。这些讲义不仅是一份极具价值的记录，展现了他当时的观点以及他对引力及其在宇宙学、超巨星、虫洞和引力波中应用的深刻洞见。讲义中还包含了诸多引人入胜的枝节

Weinberg：《Gravitation and Cosmology》——权威参考书；Padmanabhan：《Gravitation: Foundations and Frontiers》——现代视角；Feynman：《Lectures on Gravitation》（费曼引力学讲义）——费曼独到的见解堪称稀世珍宝；Mukhanov：《Introduction to Quantum Effects in Gravity》——量子引力（以及量子场论）的最佳入门书
Weinberg: Gravitation and Cosmology - The definite reference Padmanabhan: Gravitation: Foundations and Frontiers - A modern point of view Feynman: Lectures on Gravitation - Feynmans unique insights are a rare gem Mukhanov: Introduction to Quantum Effects in Gravity - The best introduction to quantum gravity (and also quantum field theory)
“正如诺奖得主 Steven Weinberg 在 1964 年指出的那样，自旋-2 粒子的存在必然导致广义相对论” 啊哈？！自旋-2 粒子导出 GR 正是 1962 年费曼引力学讲义（Feynman lectures on Gravitation）的核心精髓好吗！
"As the Nobel Prize winner Steven Weinberg showed in 1964, the existence of a spin-2 particle leads inevitably to general relativity" Huh?!? spin-2 particle leading to GR was the prime essence of Feynman lectures on Gravitation, 1962
我之前就这么想过，尤其是关于鬼魅般的超距作用。《费曼引力学讲义》（Feynman Lectures on Gravitation）里有段看起来挺有意思的内容，他大致论证了如何从自旋-2 粒子的数学推导出爱因斯坦式的时空，虽然这对我来说还是有点超纲了。我甚至一度想尝试写……
I've thought that before now, with respect to spooky action. There's an interesting seeming bit in the Feynman Lectures on Gravitation where he kind of demonstrates you can get Einstein type spacetime from the maths of a spin-2 particle though it's remained a bit beyond me to understand it. I even thought at one point I'd try to write…

……之后如果你感兴趣，不妨看看《费曼物理学讲义》卷三第 5 章，他在那里讲了自旋。他为了保持简单故意没把自旋放进 QED 里。另外要是好奇的话，还有《费曼引力学讲义》（Feynman lectures on Gravitation），他在里面尝试搞懂量子引力，结果跟其他人一样铩羽而归。我喜欢费曼的一点是他的演讲都是基于实验的——如果你把电子射向双缝，就会发生这种情况（QED）……
…after if you are keen it can be good to look at the Feynman Lectures vol III, Chapter 5 where he talks about spin. He deliberately leaves spin out of QED to keep things simple. Also if curious there's the Feynman lectures on Gravitation where he tries to figure out quantum gravity and fails like everyone else. One thing I like about Feynman is his talks are based on experiments - if you fire electrons at two slits this happens (QED)…
