Hard work tolerating him, isn't it? 
I did notice how the uses L for inductance, but then draws the letter Z: hmm. Anyway, apart from all that, to me, that was a good example of how to explain something that is relatively simple in an exceedingly complex manner. Each to his own, sure, but a few graph / phasor diagrams and a bit of basic mathematics not only gives a far better explanation of resonance but is also a lot shorter in duration. And, as a bonus, you can then digest that analysis at your own speed - unlike that presentation, where I felt that I was on a Formula One race-track!
