I spent a few years as a physics demonstrator, providing setups and equipment for the professors. The various demonstrations done by Professor Miller were all familiar to me and it was fun watching him do them. Sometimes they wouldn't work and he'd admit that, in the business of physics you learn from your mistakes.
His delivery was fast-paced and unless you knew what was going on you might get a little lost. It was great material to show in conjunction with various chapters in a course when you couldn't do the demonstrations in class.
Most of all I got a sense that he _loved_ doing physics and showing all the viewers how things worked. This is something I'd really like to have on DVD.
