Why would you want to take another professor? This guy knows his stuff, he teaches it in an awesome way (though he tends to overlap too often so we don't get to enough of the material), and he sounds like a bad guy from a James Bond movie. Seriously though, go to office hours if you get him because there is no doubt he will hate your class for being idiots (because everyone will be too intimidated to answer his questions for fear of answering incorrectly) and you will succeed. He's a great one-on-one teacher, and he also has some interesting ideas about quantum mechanics.

you must be out of your mind to take anyone other than vvv for quantum mechanics.

Get away from this guy.
