I just finished calculus 3 and ending on stokes and divergence theorem really hyped me up and now that I'm done with it, I have all this energy and excitement from it and I have the itch solve problems or learn more but I'm not sure what. I'm thinking something like mechanics, or electrodynamics textbooks? Or, are there more integral 3d geometry type theorem stuff to sink me teeth into?

I'd really appreciate some direction to put this energy into. Thanks!
