The essence of linear algebra series on youtube is great as well. It provides a intuitive guide to what linear algebra is about in 2d and 3d space with "arrow" vectors with great animations. Once an intuition is provided about matrix transformations, determinants, basis changes and eigenvectors, then it explains how abstraction of this theory can allow carry over of these insights and techniques to other domains or other abstract vector spaces. Too often learning starts at the abstracted level so intuition is lost in exchange for memorized techniques. There is a flip side of intuition-first techniques basically dumbing down everything into tweets but this video series is great at not doing that IMO.
