I've been learning (trying to learn) linear algebra by studying Gilbert Strang's "Introduction to Linear Algebra" book. There are some really mind bending sections in which he explicitly treats a concept like linear regression in terms of geometry and then algebra and then calculus and then probability and then ties them all back together.

What's really struck me is when I dive into a Wikipedia rabbit hole of linear algebra, following links for terms I don't know. I start on the Topology page, read the introduction section of 10 articles that start with "x is a generalization of y" and somehow end up back on the Topology page. Shallow exposure to the sheer volume and conceptual depth of stuff like topology and algebra has really made me respect modern math.
