There is (mechanical/optical/*) engineering, experimental and theoretical physics, and then there is maths (focussing on physical problems). I think taking these four abstraction levels could be a model for computer science. Now, theoretical physics is a bit of a troubled child however in recent years. If we map computer science aspects in not the four physics disciplines, we get: Software / hardware engineering Applied computer science Theoretical computer science Mathematics dealing with problems inspired by computer science
