Stuart Brown has a nice personality, but his teaching styles are a bit deficient. He is an experimentalist, so he is much more knowledgeable about experimental psychics than theoretical physics. He taught the class with his own handouts, instead of using the book, and there were habitual inconsistencies in the formulation of his formulas in these handouts. Sometimes it seems he would change some notation throughout the prepared paper.

I would really recommend physics students to take the 140B class from a theoretical physicist instead of an experimentalist.
