All maths relates to physics, they go hand in hand. You can't really study science without knowing maths. And you can't exactly separate maths into what's useful and what isn't. Even the most basic formulas build up to the kind of equations needed for psychics and there's no way you can just jump to that high of a level without a -- well, cheat code.

You'd be shocked how many people fear maths. Either by lack of doing it or by knowing how powerful it truly can be. Not to say it's fun or anything, just always useful.
