I've read some other threads and some other information on this, but I'm still not entirely clear on the answer. I've been accepted into UT Austin into the school of natural sciences as a physics major, but of course I have the option to change majors later. The problem is is that I'm just not sure what I'm most interested in yet. I love theoretical physics, and I love the idea of research, but I also like engineering. I also love the idea of working with studying nuclear fusion, and working in nuclear engineering and/or research. I'm hoping what exactly I want to do will become more clear in the mean time. So my first and simplest question is: Does it become easier to tell what you're most interested in as you begin and progress in your studies? Also my next question is, by the time I can tell what I'm most interested in and want to do, will it be too late? From what I've read majoring in physics seems to give you quite a few options, perhaps in moving on to a graduate program to do something more engineering based, or research based whatever I'm interested in come graduation time. Is this accurate? If I'm this unsure about what I want to do would a physics major be my best option? Any advice is greatly appreciated, thank you!
