From your post, it is obvious that you are not someone who would give up on your personal theatre studies and research. So i would say focus on your degree and keep reading up. This will keep you sharp enough. You do you!
You should check out this textbook that i go to every time i need a basic understanding of physical stuff. But of course i am only responsible for school plays and not sure if it can solve your question. Hope the above videos have helped. I am going through them too, for educating myself.
