This video reminds me of when I first went to Japan decades ago. I switched on the TV in my hotel room early in the morning about 6ish or so to be greeted with a very enthusiastic and entertaining teacher with Einstein-like hair teaching calculus in front of a blackboard. I then thought about what kids would be watching back home at that hour of the morning and I was ashamed to think of the opportunity that we in the West had lost. Incidentally, whilst there I never missed watching the program. I couldn't understand what he was saying but I sure understood what he was writing on the blackboard.
