A real nice guy and not a tough grader on midterms/finals. He really works with you on these and will give you very close to full credit if you just put down your procedure for the problem rather than actually solving it. Do NOT, I say, DO NOT try to follow the textbook over the class notes. You will pay for it if you do (not very much, thankfully he doesn't grade homework too harshly either). I pretty much followed the textbook the entire time in trying to do the homework, as I do in most classes, and, while studying for the final, it quickly became apparent that the methods outlined in the class notes were usually more effective and less confusing than those in the text. Not to say that the textbook leads you astray but you'll probably have an easier time of it if you just follow his procedure (especially for generalized forcing functions). All in all, to have not had a terrible experience in a 4-6pm class on vibrations is amazing enough for me to consider this guy a good teacher.
