This goes out as a question mostly to mathwonk, b/c he is a mathematician. Quick into, to help with my question, and b/c I'm totally new to this forum. I'm x-navy. I was an electronic technician from 96 to 02. I am a math major in his 5th year (I took 1 year to off to explore EE, and learned, I had already learned most of it). Currently I'm enrolled in Diff-geom (Do Carmo), Multidimensional Analysis (Spivak), Complex (Church), and Fourier Analysis (Korner). The () indicate the author. B/c my wife, a fellow math major, requires another year to graduate, I have, waited on doing all my requirements to graduate so that I can wait a year. To that end, I have a deal, sorta, with my dept. that I will take all the first yr courses of math grad school as an undergrad. Which isn't impressive, b/c it's my 6th yr. Ok. Now finally the question. Oh, wait, one more intro fact. I have always wanted to be mathematician AND a physicist. And I know all too well the differences. I have only taken the freshman calc. physics. But talking to physics majors, my electronics is ahead of theirs. Now. What I would like to do, is be a double PH.d, but I don't know if it's necessary. Mostly, I am interested in learning theoretical physics. But in 20 yrs or so, I'd probably like to do an experiment or 2. But mostly the theory. To that end, is it possible to catch up my physics, and do a second PH.d while I am doing my math PH.d? If not that, is a masters a reasonable idea? Or should I scratch the idea of another degree entirely, and simply take all the physics classes? and then just publish? The problem is, I'd really truly, enjoy being on the cutting edge of both. And I don't want to settle for something lesser. A question directly to mathwonk. I understand, publish or perish, is the path to tenure, and I am certain I wish to be a professor. But is it possible to be excepted as someone who publishes both pure math, and theoretical physics? Or is it suicide to consider physics before tenure? Also, what areas of pure math would you say, are in the category of mathematical physics? I think I understand PDE's are, and I am considering them as a path. But I am curious about Lie Algebras too. Mostly, I'd like to know, if any modern, (say last 20 yrs or less) mathematician, has managed to be a full pure mathematician and a full theoretical physicist. Thanks for taking time to read about my little problem!
