OOOO actually, I don't think these kind of genius can teach me(us) well. We are some elementary/not professional learners, we haven't look through the textbook before we listen to the teacher's talking, then I think I would better choose professor 涂涛.
unless, I can understand quantum physics without experimental data, just by following the textbook. Also, I should have time to study quantum, that is the next winter vacation, but I think I would rather live a good life during then.
