Where do particle physicists work?
My impression is that Black-Scholes is becoming somewhat of a joke because of the simplifications it makes. There are always new models that are bigger and better than the last one, and the only people that really understand them are the math & physics people. Quantitative finance is still alive & running. There are a limited number of jobs in it, but computational chemistry has a huge market. Its dominated by a handful of companies and is incredibly competitive (read some of the complaints about GAUSSIAN to see just how competitive from the business end), but if you can land a job there you’d probably do well. In my (limited) experience statisticians get a little bit hivey about math & physics people encroaching on their domain. Aerospace engineering companies have head mathematicians (and I’m guessing uses for anyone with the math necessary for PhD physics work).
