However, topology is one place to get good examples with which to
build intuition for category theory, so it's possibly worth looking
into from that perspective. There are lots of nice examples like the
Seifert-van Kampen theorem, which can be eloquently summarised by
saying that the fundamental groupoid functor preserves pushouts.
