math isnt about application, it's the beauty behind it.
The beauty behind it? Do you mean the natural world around you? The value of mathematics is that it meets human needs and has given us higher chances of survival with it's applications. The quality of life has improved for the majority of the world because of it. What would the human condition look like without it never being applied throughout history? Not a world that I would ever want to witness, and that's saying something. Physics will do even more for humankind one day.
I think you will regret the choice, I know that I do. But, they may not let you into this course anyway. It's not intended for mathematics or science majors, but serves as an option for other majors to take that could satisfy their general requirements. My university recommended reading material for the course is "Physics for Dummies"- I'm not kidding. This course will probably need to grade on a curve, but if you are as competent as you say in mathematics and do too well then you may be considered by your peers as the 'curve wrecker'.
