Computer science has a lot in common with physics. Both are about how the world works at a rather fundamental level. The difference is that while in physics you’re supposed to figure out how the world is made up, in computer science you create the world. In mathematics, as in programming, anything goes as long as it’s self-consistent. You can have a set of equations in which three plus three equals two. You can do anything you want.
