You know I’d actually pay the crazy fees if only I could find a place that’d reteach me advanced maths “in context”. I find often that adding context means subtracting the “advanced” part :)
Study Physics. I'd take the math prerequisites and not understand what this is useful for, and then the first week of physics class we'd review the math and suddenly it would become quite practical.
Solid advise. I think finance massively recruits maths aptitude from physics for precisely this ability to connect hard core maths to models of the world.
I wouldn’t expect a pure mathematician to be good at this nor to care about it either.
Did you ever read “How to Solve it?” Polya says he became a mathematician because he was too clever to be a philosopher and not clever enough to be a physicist :)
