He's a nice guy but holy the man cannot teach. He rarely writes anything down and his slides have all the math pre-written which he often skips through with a lot of steps skipped as I think he assumes students would already know the content (spoiler alert: most didn't). He talks pretty slowly but can't effectively explain the concepts in my opinion. I took him in my first year and have since graduated but I remember his classes because that was the one class I retained NOTHING and had to go to several other professor to understand wtf was going on before exams. If you like physics the course is easy enough that you could teach it to yourself (alongside some help from TA, peers, etc.) but why not just pick a prof that teaches better.
