So, I'm majoring in mechanical engineering, mostly because I enjoy math and physics, and was told my focus in physics would get me nowhere, and that I'd have to go after engineering if I really wanted to work. That's what I'm doing. However, I want to go into an area of engineering, or focus, where I can still utilize my interests in physics and cosmology. I've thought about getting in touch with particular aerospace companies as a starting point. Any advice?
