Calculus is unfortunate because I knew it had “practical uses” I just didn’t think those practical uses were for me and couldn’t describe what they were outside of vague references to “engineering”. Fast forwards during Covid, I was doing a lot of work on the side with retro telecom projects and for the first time in my life I wished I had paid much attention to calculus or at the very least anything before it.
