Grothendieck Topologies
Topology. It’s something that every math student has to become comfortable with. First you get to learn metric topology (usually on ), followed by point set topology. Then in graduate school, pretty much everyone gets an introduction to algebraic topology. However, it all really just studies sets with distinguished collections of subsets. There is, however, a more general version of topology, in fact, a way to put a topology onto a category due to, of course, Grothendieck.
