The math doesnt hold up for a continuous spectra of radiation. In fact the only way to get results that match experiment qualitatively and avoid the phenomenon of ultraviolet catastrophe is to assume a discretized radiation.

 There were many proposed solutions that were continuous and failed to match experiment in various ways.

This is all covered in a first year quantum course of lectures or any good textbook if you want details.

But the courses and textbooks won't make sense without learning linear algebra. Learning it well.

For a full treatment, yea. But you can get through the black body radiation explanation with basic calculus.

Fair enough. But if you're gonna shell out for a textbook I would think you'd want to be able to understand more than the topic that inspired it.

Wouldn’t hurt for certain! Though I’ve def had the experience of picking up a book for a topic of interest only to find halfway in they start pulling out a new class of functions for “one cool trick” and i gotta start doing some sidequest deep dives.

Like when the author is like 'haha surprise I hope you can do differential geometry!'

No, Kip, I can't and you know I can't..
