- If you want to get an academic job (which is mighty hard these days) you
- should realize that it's most likely going to be in EITHER a physics or
- a math department and they will usually want you to have: 1) a PhD in that
- subject, and 2) lots of papers published in journals of that subject.
- It would be a lot of work building up your career in such a way that
- your formal qualifications in both math and physics are equal, and the
- point is that this work wouldn't stop after you got your PhD. A much
- more typical thing to do is to pick ONE area to be your primary one and
- wait until you become famous before you start also claiming to be an
- expert in the other area. All this has to do with the practical issue
- of getting jobs, and doesn't have much to do with what you're actually
- interested in. It's a crummy system in many ways, the division of
- academia into narrow specialities, but if one is going to succeed in an
- academic career one must be aware of this system and have a strategy for
- dealing with it.

- For example...
-
- I'm a mathematical physicist. As an undergrad I found that I did a bit
- better in math than in physics courses, and I disliked laboratory work.
- So I majored in math. I then got a PhD in math. But I've liked physics
- all along and almost all of my papers are about physics AND math. For
- the most part, though, I've published in math journals (or mathematical
- physics journals), which means I usually publish proofs of theorems. As
- a result math departments were reasonably sure I wasn't just a physicist
- pretending to be a mathematician, and were willing to hire me and give
- me tenure. Now that I'm slightly more established I am more willing to
- play the physicist as well... but when cornered I will always admit that
- I am a mathematician, professionally speaking.
-
- Doing a PhD *simultaneously* in math and physics sounds almost
- impossible to me. Maybe there are some places where it can be done, or
- maybe you have twice as much energy and time than other grad
- students. But I suggest that you get a PhD in one or the other, which
- needn't prevent you from taking courses in BOTH subjects, as I did.
-
- Get a physicist to explain what physics general exams are like. I'm
- glad I never had to do those.
