I think the videos serve as an introduction to some basic concepts intended to bring some clarity for further in-depth study. The video is much like the &quot;front matter&quot; to a chapter in a book.<p>Of course, the _REAL_ learning work starts when the student suffers through countless problems and proofs. This is no replacement for that. One doesn&#x27;t learn math by passively watching videos or listening to lectures. That&#x27;s the way it is and that is the way it will always be. This just provides a clear 30,000 foot view of the topic, a little motivation and background and, yes, some eye candy (and that&#x27;s OK too).
