This is fascinating to me because the calculus (and, indeed, the linear algebra) I was taught was so much drudgery and remembering rules, and it took other means to build a better intuitive feel for what was actually happening.

Found this article thanks to a Reddit comment. Every day or so there's someone asking in math reddits what "dy/dx" means or why there's a "dx" in the integral notation, and then an army of people come out of the woodwork to push the orthodoxy of limits like some stockholm syndrome prisoners... And a small number of people point out that nonstandard analysis is actually a real thing and works... Anyway, back before I was born Sullivan did an actual experiment on teaching
