Report Two different teachers, which one should I choose? in The Fingerboard Posted July 31, 2005 Well put, Hanxiao. When I was a Ph. D. student in literature, I sat in on a Physics class taught by a Nobel laureate. An extremely nice guy he was, but there was not much in my head after the class except for his jokes. Then his co-teaching professor came in summarized the material etc., and all of the sudden, I realized how much I should have learned. :-( I am sure the Nobel laureate is much better established in the area of Physics than his colleague. But it was the non-laureate professor who really hammered the material onto my head. Just for the curious, why a Ph. D. student in literature would audit a Physics class? Well, one day I woke up feeling like being a physician and so I need to take some science courses to fulfill pre-req for medical school. Physics was one of the pre-reqs.
