This is truly the best lecture I've ever taken.... Every time the instructor says the introduction got too long or that they went off on a tangent, it's exactly because of these additional explanations that I can really understand properly.... Please go off on many tangents.... What someone like me who lacks foundational knowledge needs is basic general knowledge.... I couldn't understand because I lacked basic general knowledge, but since you're building up that foundational knowledge too, I'm really understanding properly now. I highly recommend this course.
