Grad School Open Thread

Today is Grad School Recruitment Day at Caltech, from which I surmise that there must be dozens of readers of this blog who are currently puzzling over where they might want to spend the next years of their lives. And hundreds of readers who went through this puzzling at one point themselves, or will face it in the future. So, since "work" is preventing me from blogging very much, here is a place to share stories and questions; we've previously given advice, but you can never get too much. (Professors, did you know that these students are talking about you behind your back on the internet? A brave new world etc.) My grad school story: I was an astronomy major at Villanova as an undergrad, but knew that I really wanted to do physics. Nobody in my department was really qualified to give advice about grad schools in theoretical high energy physics or cosmology, but there was a big book put out by the AIP that listed programs and the people working in each specialty; not sure if the book still exists, or whether it's been replaced by a website. So I applied to five different places, all top-notch; got into three, waitlisted at one, and rejected at one. (I had a not-completely-unheard-of profile: small undergrad school, great letters, good but not perfect grades and GRE's, vague and untutored desire to unify all of theoretical physics.) I wanted to stay on the East Coast for personal reasons (= "girlfriend"). Sadly, the school that rejected me (Princeton) and wait-listed me (Harvard) were the ones on the East Coast that I had applied to. So I visited Harvard myself to plead my case; to no avail, of course (I wouldn't recommend doing this -- it won't work and can annoy people), but I was told that if I could get an outside fellowship they would accept me. And then I did get an outside fellowship, from the NSF; but Harvard still wouldn't accept me. Apparently that was a bit of a tactic. So I called up the astronomy department and asked if they would let me in. They were a bit surprised that physics wouldn't accept me, given that I was free, but happily took me on. Which explains why I have no degrees in physics, even though all of my subsequent employment has been in physics departments. Did it matter that I went to an astronomy department rather than a physics department where my interests would have been a more natural fit? Absolutely -- I hung out with people who chatted about redshifts in their spare time, not with people who chatted about Feynman diagrams, and that lack of immersion in a crucial subject has undoubtedly been a handicap. But I was generally in a good situation (you can't really complain about being at Harvard), and I made the most of it -- took many physics classes, spent time talking to professors, wrote papers with other students and mathematicians as well as my advisor, went to MIT and ended up collaborating with people there as well. If you go to someplace that is decent enough to offer opportunities, it will be up to you to take the initiative and make your time there a success.
