With these tools, you can learn:
Theoretical mechanics (I recommend the first and second volumes of Mechanics by Liang. If you have a good foundation, you can read the second volume directly, as well as the complete solution of Ju Guoxing's theoretical mechanics exercises. These two books are very conscientious.
Thermodynamics and Statistical Physics (an English book named "The Concept of Thermophysics" is recommended, but Wang Zhicheng's thermodynamics and statistical physics used in many schools are not recommended).
Later, in order to learn deeper content, we must learn a new mathematical tool, that is, mathematical physics method (recommended Liang's "Mathematical Physics Method", clear and clear)
Then there is:
Electrodynamics (I have never met a suitable textbook. . . As simple as Griffith, it's much more difficult, because I didn't find a suitable textbook when I was studying, and it was basically a teacher's courseware)
Quantum Mechanics (Quantum Mechanics by Zeng Jinyan is recommended by China's textbook, but I always think that there are only two textbooks for the first echelon of quantum mechanics. One is Dirac's original work: Principles of Quantum Mechanics, which is the originator of quantum mechanics. Because there are many translation errors, it is recommended to read the original; The other book is Modern Quantum Mechanics by Japanese j.j.sakurai, which is highly recommended, especially the first 30 pages of Dirac's original work, and explains the logic of quantum mechanics very thoroughly. )
Solid state physics (Juan's solid state physics is recommended, and China's solid state physics master Huang Kun's solid state physics is also recommended).
Principles of optics (no suitable textbook)
After that, math tools were not enough, so I had to learn.
Group theory (S.Sternberg's Group Theory and Physics, others don't know)
After learning group theory, you can learn some tall ones.
General Theory of Relativity (textbooks are random, domestic textbooks are not recommended)
Quantum field theory (textbooks follow fate, domestic textbooks are not recommended)
At this point, the mature physical theory system of human beings has been won.
