Hey guys, i just started my undergrad studies, and by the end of year one i will need to select my "Major" (this is a danish school so it's not quite the same system as USA, but i think major is about the same). Basicly i can choose from Bio/astro/geo physics, as well as just pure physics and meteorology (sp?). I'm kinda torn in what to select, astro is what kind of interests me the most, but i don't see it being very applicable in the workmarket apart from a teaching job. While pure physics is also fun, it's a LOT of elective courses. Geophysics and meteorology don't really interest me that much (although the school is aparently very advanced in the whole glacier drilling thing). Biophysics DOES interest me to a point, it does seem interesting, and also it seems like a field where a lot of interesting research is left to be done (and i'm thinking a biophysicist would have more marketable skills then an astrophysicist). Couple this with that i'm not really too sure in what field i want to be in and i'm pretty much at a loss :) the most fun to me would seem to be going into the astrophysics, but i'm unsure how much that limits my choices after my BS degree. Is it easy to switch directions to some other field of physics after my BS if i find something else more interesting? Or am i confined by my undergraduate studie direction ? Also, in regards to the biophysics. It does interest me to an extent, but i've never really had a big interest/knowledge in biology. Are biophysics very similar to biology or is it more "physics" oriented (not sure really how to put to words what i'm thinking about).
