I’m really not sure I see your point. This is about math and physics, so I would assume anyone who writes about it writes about the same things and has similar diagrams. Also, this is not a scientific paper. As long as words, diagrams or very specific and very novel ideas (nothing of that kind seems to be happening here) are not lifted directly I really fail to see the problem. My math and physics textbooks in school didn’t contain any citations either.
