## Idea

Algebraic topology is generally the study of functors from nice categories of spaces to algebraic categories. This is in hindsight, in fact, category theory originally developed out of algebraic topology, where it was used first simply to describe what was going on and then to axiomatise Eilenberg-Steenrod cohomology theories.
