Mathematics and physics in junior high school and senior high school are basic subjects. The so-called foundation is that what you learn can't meet your scientific research. If you go to college, you will find that everything in science chemistry contains physics, and physical chemistry cannot be separated from mathematics. Therefore, if you want to engage in scientific research, you must first pass the college entrance examination. Mathematical physics in junior and senior high schools can't be said to be completely useful, but it can't be said to be completely useless, because the content of the university is the tacit understanding of many knowledge points in junior and senior high schools.
