…扎实的知识对他们有多大帮助。先从简单的书开始，循序渐进。Goldstein 和 Landau 是极好的中阶选择。对于初学者，我觉得 Jakob Schwichtenberg 的《No Nonsense Classical Mechanics》或者 Leonard Susskind 的《Theoretical Minimum Classical Mechanics》都不错。我个人非常喜欢 Jakob 那本。卡壳的时候，你得有个朋友或者线上学习小组帮帮你。经典…
…much a thorough knowledge will help them. Start with an easy book and work your way up. Goldstein and Laundau are excellent intermediate level choices. For a beginner I think Jakob Schwichtenbergs "No Nonsense Classical Mechanics" could work or Leonard Susskind's "Theoretical Minimum Classical Mechanics" . Personally, I really liked Jakob's book.

Self-learning via books. I've bought a bunch. Am currently going through Susskind's Theoretical Minimum Classical Mechanics [1], also looking through No Nonsense Classical Mechanics [2]. AI chatbots sometimes come to rescue when I am stuck. Not with mathematics though. [1] https://www.amazon.com/Classical-Mechanics-Theoretical-Georg...

我见过对勒让德变换（Legendre transform）最好的解释，就在 Schwichtenberg 写的《No-Nonsense Classical Mechanics》附录 B 里。
The best explanation of the Legendre transform that I have seen can be found in No-Nonsense Classical Mechanics by Schwichtenberg, Appendix B.

靠看书自学。我买了一大堆。目前正在啃 Susskind 的《Theoretical Minimum Classical Mechanics》[1]，同时也在翻《No Nonsense Classical Mechanics》[2]。卡壳时 AI chatbot 有时候能救个急，不过数学部分就不太行了。[1] https://www.amazon.com/Classical-Mechanics-Theoretical-Georg... [2] https://www.amazon.com/No-Nonsense-Classical-Mechanics-Stude...
