- WoahNoun 4y agoHa! True enough. It's long joked that much pure math research is resolving really hard problems down to a calculus or linear algebra computation. When I first learned differential geometry, I was enamored with all the stuff we could do without coordinates. Then I learned Riemannian geometry and felt like I had been duped.
