Anything related to engineering.

Its heresy but its hella useful.

partial differential equations.

all pure mathematicians working on memetopy type theory or the like know that PDE is the most important and rich subjectt but know that they cannot handle it because they lack the raw problem solving ability and they would just be flailing and scratching around in the darkness like weak babies so they cower from the rich and important central subject of PDEs and instead make up nicely categorisable, autism-friendly , niche, meme fields in algebra.

Modern algebraic geometry. I don't think anyone knows what the fuck they're talking about anymore.

who would win in a fight, differential geometry or algebraic geometry?

>>8642116
String theory. Literally pseudo-science.

>>8642116
ZFC Set Theory.

>It is impossible to create a finite first order theory for field theory
>It is possible to define all of field theory within the finite first order theory of ZFC Set Theory

Literally how?

Algebraic geometry, but the algebraic geometers wouldn't understand the concrete concept of conflict, so they wouldn't even understand that they won. In a sense the differential geometers would also win, because facing the dark arts of the algebraic geometers would leave them with new ideas to advance their field.
