Symplectic manifolds and big stones

February 15, 2017

Before I stepped away from mathematics, I was heading to the study of differential geometry. Which since has become quite popular, and even contentious. Mohamed Abouzad explains the lack of a complete proof for one of its major conjectures thusly:

There are two conceptions of mathematics. There’s mathematics as: The currency of mathematics is ideas. And there’s mathematics as: The currency of mathematics is proofs.

I think I agree more with Dusa McDuff.
