How much a person knows about a subject depends on his "back" or his understanding level. I believe many people think that science is memorizing formulas. So I suggest you discuss with your peers whether your structural mechanics is "too liberal" before asking about the liberal arts components of other professional courses. If it is a matter of your own understanding ability, then you are probably not much better at studying quantum mechanics. You need to remember a few rules and formulas, and you can do almost all the problems, which is nothing like liberal arts. Structural geometric composition analysis is the most basic thing in structural mechanics, and those laws are only a few words, just like Newton's three laws of Newtonian mechanics. If you think that scientific things do not need to remember some necessary concepts and experiences, it is all wet. Besides, experience comes from doing problems. You usually don't study or do problems, and the exam is not ideal. You think you have a good IQ just because you can't remember how to go to school. I can only learn science. Memory is also a part of IQ. If you can't learn for other reasons, don't say you don't like it, because the liberal arts attribute of structural mechanics is too high. Otherwise, many pure science courses have many concepts, theorems, inferences, axioms and formulas, which are difficult to learn. Of course, if you can learn quantum mechanics and pass the exam, it is still very good. If your English is good, you can try The Secret of Quantum Mechanics. This textbook is very useful for understanding quantum mechanics, and then you suddenly give a formula without explanation. This book lets you start from scratch. In addition, if you are interested in quantum physics by reading popular science, be prepared to change it later.
