Hello, I am a physics-maths double major and a rising sophomore at a US university. I currently have a "research" position with a professor, but its more like I asked nicely and the prof did me a favor by giving me the position. I don't do more than a few hours of work a week. So, I need a summer job to cover some expenses. My question is, is there any field of work that will look at least tangentially related to physics/maths and is still accessible to a college undergrad over the summer? I want to make money, but then again I don't want grad schools to think I "wasted" the summer, so are there any interesting suggestions for jobs I could apply for that are related to physics or mathematics? Besides tutoring, that is (I am trying to get a tutoring position as well, but am well aware of that opportunity and am curious about others).
