It seems in different countries (and universities) Computer Science mean different things. In my country, Computer Science is exclusively theoretical study of some areas of mathematics. You don't go into CS to run experiments, just like in mathematics. You go to study theorems and complexity theory. Anything related to the act of developing software is called Software Engineering/Informatic Engineering. Totally different things: as different as a mathematician and a bridge builder. In the real world there's an evident intersection between CS and SE, but in academia (in my country), CS _is_ math.
