Because computers include many subjects, if you want to learn programming and so on, you must not be bad at math, that's for sure!
Physics is rarely used in some fields of computer. Knowledge is a step-by-step process, and all knowledge must grow together.
Optics can't do it, and I will encounter bottlenecks and can't break through myself! Of course, if you just want to study general computer science, you don't want to make greater progress in this field, and you don't need to study so many other courses. It is necessary to study if you want to have excellent skills in this industry. The more knowledge you learn, the more you feel!
