When i do mass, people go, oh, you must be good at memorizing. And my answer to that is always, you know, i like mass because i don't have to memorize. If there's a formula and i know where it comes from, i can derive it, i can get it back. When we look at a formula as a story, then it helps us connect rit. The more you can make stories and connections and reasons, the better it allows a student to learn.
