It does? That doesn't match the way I think about linear algebra at all.
Interesting… did you read the jadagul post? “The entire subject is, like, four actual facts, each of which is repeated twenty times in slightly different language.”
It's really true, I heard this freshman year, studied linear algebra over the summer and tested out of it. So glad I didn't waste a semester on it.
I suffered all the way through it, but did manage to figure out the key near the end of the course.
Only problem with this is that everyone comes out thinking it's a slightly different couple of ideas (the list in that post is great at explaining why)
Isn’t that the reason it would be good to say this up front? “These dozen things are all the same thing, so learn one of them thoroughly first, then understand how the others are it in disguise, and when to use each.”
Have you checked @3Blue1Brown's gorgeous series Essence of linear algebra? https://www.youtube.com/watch?v=kjBOesZCoqc&list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab …
I guess you'll find this video of him interesting, on what does it feel like to invent/discover/enunciate math:https://www.youtube.com/watch?v=XFDM1ip5HdU&t=5s …
Or perhaps it would be more difficult! Some learners thrive on mystery and novelty. “Here are the ideas we’ll do reps on for the next 15 weeks” = discouraging
Personally I found the math classes that posed mysteries & promised a revelation more compelling. Notable one: “why are there 5 platonic solids?” (many weeks of group theory later) “here’s a proof”
