My dad suggested I take commerce too but I'm too much of a dork for that stuff, heh. The history aspect of physics will get me jack squat unless I go on to graduate school with it and teach it. It's really just a hobby that I can pass off as education and thus, have my parents pick up tuition. As for applied nuclear physics there are all kinds of jobs.
For instance, in the 50s nuclear fusion was discovered and led to the hyderogen bomb. Fusion bombs are easy to make as all you do is fuse hydrogen nuclei together to make a heavier element, Helium. This has yet to be a controllable reaction and thus all that has been done with it has been weapons manufacturing. If we can figure out how to control nuclear fusion we can create a lot more energy from the most plentiful element, Hydrogen, which makes up about 75% of the Universe. Nuclear fission, which is what is going on in your average power plant requires rare isotopes of certain rare elements to be harvested and sometimes created like plutonium.
The atom is the ultimate power source and if we can harness and extract its energy combined with miniturization we may one day find our bikes being powered by little fusion generators (With a big-bore internal combustion engine sound of course). Forget overpriced fossil fuels, just pick up a 1 kilogram stick of solid hydrogen (you'll be able to make your own) and you'll be able to run that beast for well over a century.
I've made quite a mess but this stuff is as intoxicating as riding, sorry. It all comes down to this: When and if I leave University I want to harness some energy source and somehow apply it our bikes so they run faster and cheaper
