Great lectures and works well with TA to make sure sections are helpful also. Office hours are more than worth the student's while. Very friendly, very straightforward, very good teacher overall. His homework prepares you for his exams, both were challenging but manageable.
Really friendly!
Hands down the best professor at UCSB. He makes class fun, it was the first time I looked forward to going to class because of the professor (and physics of all classes). He's so helpful and has a genuine interest in the subject and really wants all students to do well. His tests are straightforward and he's really helpful and funny.
