Prove, in what sense?

It's interesting what you consider to be "worth reading." I'm not particularly well versed in functional analysis (which that second paper is about), but I know for a fact that the theory of isometries between Hilbert spaces has been indispensable for quantum mechanics.
Is your approach to math "if it's beyond my level of understanding, it can't be useful?"

Yes, in math, you prove everything.

Ok, what I do is basically applied maths, although it's not what people who applied maths/theoretical physics would call applied maths.
When I read about theoretical physics they don't use rigorous mathematics at all to do anything. i.e. Definition: A particle is... Definition: An electron is... Theorem: When electrons do...this happens always. Proof: If you do that way you really get proper rigorous mathematical results, not this kind of hand waving, easy to pick apart, unproven tripe. That's why I hated physics when I was an undergraduate. They don't do anything or go anywhere, just write a load of equations down and say "see we proved that". Go to my website, and read some of my papers www.combinatorialgametheory.com, that is what applied mathematics should be like.

Sorry, you're just wrong here. MerriamWebster says that "maths" is just fine:
http://www.merriamwebster.com/dictionary/maths The BBC uses "maths" http://www.bbc.co.uk/programmes/p00t6kkg (See paragraph 3) The Cambridge math department also uses "maths": http://www.maths.cam.ac.uk/. (See upper right, and the web address) Why don't you write the Cambridge math department and tell them that they're using the wrong abbreviation for their subject? I bet they'll be impressed by your assertiveness.
