Professor Regan knows his stuff, and that's an understatement. He clearly has an extraordinary grasp of quantum mechanics and does his best to impart that to students. There's two downsides to this, though. The first is that it makes it hard for him to realize that students may have some difficulty with the concepts. They might be second nature to him, but they're entirely new to us. Yet he assumes that we are as comfortable as he is, and races through topics like the goddamn Road Runner getting away from Wile E. Coyote. The other problem, though (and this is arguably the worse of the two), is that Regan's self-perceived mastery of physics makes him an insufferable asshole. Just absolutely so far up his own ass, he's basically wearing his head as a beret.

With that said, I will reiterate that Regan is very knowledgeable, and he does at least try to share that with his students. Sometimes he goes a bit too far and too fast, but it's clear he is making an effort, which I appreciate. And it works. I do feel like I have learned a good amount in this class, that I may not have if he had not focused on the fundamentals like he did. In addition, his exams are insanely difficult and nearly impossible to finish in the allotted time, but he seems to be fair about grading and curving them, so the end result isn't too bad. Moral of the story then: really smart guy, raging asshole, medium teacher overall.
