Couldn't you also say that its impossible to condense calculus into 10 minute chunks because you have to understand Algebra first? All learning requires context, but that doesn't have anything to do with whether can break it up into courses, books, chapters, lectures, or 10 minute chunks.
Absolutely. But you can't teach calculus in 10 minutes. Pretending you can teach 40 years of 20th century history in 10 minutes is just silly, even if you are just giving an overview. At some point, the overview becomes meaningless and information free.
