I spent the better part of four years in graduate school teaching various flavors of introductory physics. It was even enjoyable, after the first year, since then I had some idea of what I was doing. It was especially enjoyable if the students were bright and well-prepared, since that meant I could be lazier and duller. Some day I'd like to have a free hand to really do it right, but that'd mean not only becoming an academic for life (probably my fate anyway), but getting tenure, by which point, what little I remember will all be wrong.We dress like students
(I was also the grader for PANZ 619, Biology of Mind one semester, which was instructive, but not an experience I'd care to repeat, at least not at that salary.)
I was quite proud to be a union member; in fact, I was one of the physics department stewards.
On the off chance you end up taking a class from me, I warn you to read my student evaluations.
