For me it's algebraic geometry and category theory. This shit is just too divorced from any reasonable intuition.

Wtf is Z[Z] or Q[Q]? Polynomial rings with countably infinite variables? If so why "Q[Q]" instead of "Q[Z]"?

if i had to guess without knowing, it might be because Q is dense

From all that crap what is actually useful for applied math / engineering?
Serious question.

Group algebras are noncommutative rings that I like.
