this makes me want to learn more about bivectors and other types of matrix(?) products. I've bumped into a few years back like the redheffer star product, kronecker delta, tensor products and whatever else. But I always used them as a tool for simulations and didn't really understand where it all comes from beyond intuition. Where do you go to even learn this stuff? Differential geometry?
