   The depth and breadth of topics and examples is amazing. Well done! My only nitpick would be the formatting of some of the equations. Instead of $$ E = hf $$ $$ E = (6.626 \times 10^{-34})(10^{9}) $$ $$ E = 6.626 \times 10^{-2

   Completely unrelated to the video speedup hacks, but also in the vein of getting a lot of information across faster, one thing you can do for your courses would be to create Concept Maps. The CmapTools software is very good for this: https

    That's certainly a big factor for primary school, but using the same "education as daycare" model for high school students feels very wrong.

    I came to say the same thing. Very interesting design indeed. The titles appear onmousover for the "bookmarks" -- although I don't think the are bookmarks but stacks of punchcards.
