btw your last remark made me think, do anyone of you guys and gals know someone that has done two phd theses for two different uncorrelated subjects?
I had a professor who had two Ph.D.'s, probably both in science (two chemistry I think). I know someone who is doing a second in physics, but in a quite different subject than his first. And I believe a famous French author (Albert Jaquard) has 3, which I believe are anthropology, genetics and sociology or something like that. I'm also aware of people with M.D. and Ph.D. (in physics), (and even someone who is both a dentist and a doctor).
Oh, and one of the characters in the film Armaggedon (Bruce Willis, Ben Affleck etc.) has "a double-Ph.D. in geology and chemistry from MIT". In the context of the movie, I think he works has a researcher for a petroleum company.
As for combining psychology and physics :
- Neural networks, artificial intelligence (creating artificial decision making systems and simulating thought and "minds")
- Imaging: MRI, Nuclear medicine (finding out where chemicals, hormones etc. go inside the brain as a function of feelings, mood etc.)
- Education : researching what are the best ways to teach various areas of physics to various groups of people
- Modelling societies : Applying statistics, calculus, chaos theory, or any mathematical methods to model how population groups (human or animal) behave, feed, move, reproduce, consume etc. Although, this is not so individualized as a psychologist might like (unless you call it "mass psychology").
