……化学。Softley 的《Atomic Spectra》和 Keeler 的《Why Chemical Reactions Happen》也是极佳的入门书，不过涵盖的范围比前面提到的两本要小一点。前面提到的那位 Atkins 还写了《Molecular Quantum Mechanics》，同样是一本很扎实的好书

PW Atkins 和 RS Friedman 写的《Molecular Quantum Mechanics》。算是一个挺小众的领域，但这本真的很出彩。预备知识是需要相当扎实的线性代数和微积分基础。它……

……在入门级量子力学教材里常常给出的那些非黑即白的案例中并没有得到探讨。我现在想不起什么必读的参考资料，但如果你对这类东西感兴趣，我知道有两本关于分子量子力学的书；一本是 McWeeney 写的（分子量子力学方法），另一本是 Atkins 写的（分子量子力学），后面这本我自己没读过，但我听说很不错。我不知道有什么免费的在线资源可以……

……拼凑一些事后诸葛亮的论据和简单化的叙事，我觉得这只会让本科生更难受。也许“科学史”应该单独成为一门学科？有些教科书（比如 Atkins & Friedman 的《Molecular Quantum Mechanics》）视角就更细致入微一些。他们把经典计算在绝对零度附近固体热容上的失败，与黑体辐射并列呈现：> “爱因斯坦认识到……

……这就把我们带入了数值解、群论对称性论证等等的领域。如果你觉得这个话题很有趣，我建议你搞一本 PW Atkins / RS Friedman 的《Molecular Quantum Mechanics》，可能还可以读读 PCW Davies 那本有点半科普性质、但公式实在太多了的（1979 年）《The Forces of Nature》。（虽然没讲分子，但在背景知识方面非常棒）https://www.amazon.com/Forces-Nature-P-C-Davies/dp/052131392...…
