Set theory is how you prove arithmetic works. Prove 2+3=5.

I didn't say that set theory is not *important*. I said it is not
*interesting*. Certainly not to me, anyway. The obvious stuff is
obvious, and the non-obvious stuff is all tedious riddle-like splitting
of hairs rather than interesting insights.
Also, several sources state that set theory is the fundamental basis of
all of modern mathematics, but not one single one makes any attempt to
explain this sweeping statement. Your assertion that set theory somehow
has something vaguely to do with arithmetic is typical of this type of
statement. If there *is* some kind of connection between set theory and
arithmetic, it is highly non-obvious.

It's interesting if you want to know whether arithmetic is complete and
consistent, for example. Godel's theorem certainly is an interesting insight.

And *that* is what makes it interesting! Set theory is like the lambda
calculus - it's tiny and trivial, but you can prove anything with it.

I've never read them (nor did I see any of the movies). I too heard tell
that the books were rather bad, but my father insists that while the
German translation sucks, the English original is actually quite good
(he's a retired English teacher, and none too easily impressed by any
"hype", so he may be a comparatively credible witness after all).

It's an interesting picture of an establishment. You get accepted as an
expert by agreeing with the experts.

... despite there existing proof that this desire is insatisifiable
(which I find an interesting thing to know, too) - and not only in this
world, but also in any imaginable one (another interesting thing) except
for pretty boring worlds.

Hehe - when I was a teenager, I wrote a raytracer, too - without even
knowing POV-Ray; all I had was a few printed b/w chrome spheres on
checkered planes, the desire to do the same, Snell's law, and a
classmate who took over the task of developing UI components for the
interface (we didn't have a library for that either) :-P
Needless to say that the thing was awfully simple, and did not even work
properly - it got the normals of non-uniformly scaled spheres wrong -
but hey, you can't do everything right all the time, can you ;-)

You don't need unshakable solid proof for conjectures, so maybe you
should stick to those. In my eyes that's mathematical enough.
I guess more often than not, proving a good conjecture boils down to the
mere applying of rules again. Sure, there are famous conjectures out
there that seem to defy any attempt to prove them, but you don't hear
about the conjectures that are easy to prove. And after all, /every/
proof starts off as a conjecture.

suppose you have a set of 2 things and a set of 3 things. How many things you
have in total? Is that not how you even learn basic arithmetic?
functions? a formula mapping things from a set to things from another set?
yeah, set theory is fucking huge.
