Pure maths and analysis don't really bother me. So ignoring it, espically analysis. Saying that in a month I might start reading up on complex analysis and stuff like proof of intermiediate theorem e.t.c.
But, on that. I've been trying to learn PDEs and QM. Both are sort of gay. Like a book on PDEs that is recommend text first chapter goes on about naive stroke equations, its like if the prize money is a million pounds to solve it, am I meant to understand it or something?
Also, the QM book is even worse. Its like they pull out a random equations and say here. Its like can you show me how you derived it, which is gay because they use pictures instead of arguments. A picture isn't a mathematical proof.
Like one of the question is this
Assume that an electron is located somewhere within a region of atomic size. Estimate the minimum uncertainty in its momentum. By assuming that this uncertainty is comparable with its average momentum, estimate the average kinetic energy of the electron.
Yeah, don't even really know where to start with this. Well, I do i.e. looking in the back of the book for anwsers.
