The eternal paradox of math textbooks: they either show you incomprehensible abstract geometry that looks like it was drawn by someone having a seizure with a ruler, or they throw in completely random pop culture references as if Shrek will somehow make partial derivatives click in your brain. Nothing says "I understand vector fields now" like seeing an ogre explain curl and divergence. Next semester they'll use SpongeBob to demonstrate Fourier transforms. The textbook publishers are just trolling us at this point.
