I haven’t read the whole thread, but should jump in to correct the record and offer an opinion
Re #220:
Appreciate the correction, but this isn’t true. The relationship between what’s listed in a registrar’s course list and what is actually taught is not always straightforward. At my shop, for instance, I have taught four different courses over the last six years with the same number and title. This is not unusual – in a small department like mine (I’m at a top-tier liberal arts college, a peer of Swarthmore), we often teach advanced topics courses as “whatever I’m thinking about these days” and have the flexibility to vary topics according to student interest and goals. I wouldn’t be surprised if it’s like that in some other fields as well.
Mathematics is somewhat different, though, in that any faculty member (with doctoral training) knows enough to teach a course on most any subject in the usual curriculum at an advanced undergraduate level. So our course offerings are driven more by our general intellectual interests (and those of our students) than by our research areas.
On another note, I should mention that in math, choosing one’s undergraduate institution based on faculty representation in one narrow subfield of initial interest is not really a good idea. I recommend that any student who is serious about studying mathematics at a high level aim first for broad exposure to the subject, with a view toward developing general mathematical maturity/sophistication and (more importantly) intellectual independence. The vast majority of the math I have learned has not been in any course, but has come about because I wanted to learn something and was prepared to sit down and teach it to myself. I always advise students to approach their education with the knowledge that some day they will “run out of courses.”
All that said, I do have some specific college recommendations for a student who is interested in intermingling math and politics (something I happen to know a bit about):
LAC: Union college in NY (perhaps the best choice), Carleton College, Harvey Mudd.
Universities: Tufts University, UC Irvine.
Not sure how many of those were mentioned, but I do know faculty at all of them who are good teachers and study this subject.
EDIT: Please forgive the long-windedness! I didn’t have time to compose a shorter post
