I'm just starting my sophomore year as an undergrad and am thinking about my major. I'm planning on getting a doctorate in Aerospace Engineering and was wondering which minor would be most useful/appropriate. For my actual job, I plan on doing research and development for some Astronautical company. For minors, I was thinking about these: Mathematics, Physics, Astronomy, Computer Science, Computer Engineering. These are the ones I was thinking of which means I don't know of all the possibilities. If you have a suggestion please do tell. My favorite is Math. I love math with a passion and am always dying to know more. From what I hear, math is more important for physics majors than engineers. I am of course talking about the HIGHER math classes. I think Math would be useful for completely understanding the world of Physics so I can possibly apply it to research. Of course I can also minor in Physics and get the required math for that. Still, I don't know which is more useful. PS: What's the program called where different university accept students from other colleges for research opportunities. I think it's on a government site but I'm not sure. I'm planning on doing one of those in the summer.
