Desperately need some advice PF, thanks so much for any input! Background: I am going to change my major from physics/astronomy to applied maths, for two reasons: 1. I seems to have more of a natural ability in math and programming than physics style problem solving. 2. I will be able to finish more quickly. I can already sense the reply from someone telling me that finishing more quickly is irrelevant but right now it is very relevent to me for various reasons I will enumerate if asked. Inquiry for PF I would like to get involved eventually in either solving physics/astronomy problems in applied math or doing something like mathematical physics. What are my graduate school options in this regard? I've only taken Intro Physics and Astronomy so far and plan to study more on my own and perhaps take classes eventually if I was gearing up for admission to grad school. ps. There is a very slight nagging sensation in my head that I should stick out physics and astro and take longer, but you must understand this is balanced again various other things going on in my life. Can an applied mathematician go to physics or astronomy grad school? Or, at least as an applied mathematician can he find a rewarding career dealing with physics or astronomy problems in a academic or lab type setting?
