That's because he's so passionate about the subject matter. I gave up studying physics in secondary school because my teacher was a disaster. Instead of trying to impart a deeper understanding of the subject matter in question, he would focus on getting student to learn off scientific definitions word for word (i.e. having all the "ands", "ats", "is'", "the's" in the correct place). So you would have a textbook answer memorized for the test (perhaps), but sweet fuck all actual knowledge of physics. To see this kind of passion is refreshing, and the way things should be. (If you've ever seen 'The Wire', seasons 4 & 5 have 'Mr. Prezbo' teaching maths. He struggles to connect with his student until he teaches them how to apply probability theory to dice games, allowing them to gamble more effectively. Unfortunately for him, he also has to 'teach to the test' so that the school can say standardised test scores are going up).
