very heavy workload with (about 10-15 hrs homework per week to expect) but the professor is very helpful who add extra office hours(3 hrs per week and he stay late until you asked all your problems too). He knows a lot intersting facts about physics career too internationally. and also he's a very funny professor who can always make hard lecture funny and make you more interested in the subject. TA constantly come to lecture to hack what's the process of the course so that the discussion is a perfect reinforcement of the lecture.
the homework is challenging (usually 9 problems per week, 3 is DIY by professor) but also intriguing which really help you understand the material.
The exam is too much though. I can't finish all my problems during the midterm.
But in general, If you are here to persue knowledge (or plan to go to graduate school) take with him. the extra knowledge he provide will for sure benifit you for your further career. and the patentness of him are for sure will help you catch up with what you haven't learned but all the others knows. -- as long as you are willing to spend time on the subject.
on the other hand, if you are looking for a easy A, then take with others, the course is fulfulling but definitly can not be described as easy.

He is cute, funny, but also knowledgeable and engaging. Homework and exams are not at all easy, but the grading scheme counters that, and you really learn a lot through his assignments. Though sometimes he will be a little bit jumping back and forth (probably because he's TOO smart), the overall lecture is clear in logic, detailed in explanation, and filled with funny cold jokes 8*). One of the best physics professors for a physics lover!
