Graduate school

When I was a freshman, Freeman Dyson visited my college. He taught a class for non-majors and gave a couple of lectures for the physics students. One that I attended had a number of us, including Dyson, leave the lecture hall to go to the theater and watch the Matrix. One thing he said at the time stuck with me, at least the concept (since the words didn’t). That was that physics was something you do and not what you study, that you needed to get involved in research and not just take classes.

I didn’t truly understand this idea and internalize it until I almost dropped out of my third year of graduate school. It has become one of my guiding philosophies as a physicist and physics professor. 

I have observed that online graduate degrees are popular (universities withstood moocs but risk being outwitted by opms). I don’t see the point of them. Even a non-lab undergraduate degree loses out on a lot of value being online only and graduate degrees lose out on most of their value. I think that a good undergraduate degree should be 70-80% course work, a masters degree should be 30-50% coursework and a PhD should be around 10% coursework. The non-coursework component can be done with industrial mentors instead of academic mentors, but the good mentors will generally be at the same location as the good academic mentors. Who is going to do the legwork, and how is that legwork going to be valid, for industrial mentors in a location without the academic mentors?

I think the real signal with these online graduate degrees provide is that new things have been learned. But that isn’t the purpose of a graduate degree.

Since I graduated with my PhD, I have continually learned new things and worked in new fields. I have never taken a course, just reading papers (and books sometimes) to understand where the field is or to find a good technique. I think that instead of doing this that many people are taking a Masters (and spending money on it). They do get a certificate that others can see, but they don’t get the deep knowledge that traditionally comes from a Masters (or PhD).
