As an undergraduate, how do you know when your adviser actually intends for you to get work done and do something that might be publishable? I'm in a liberal arts college with low emphasis on research, so sometimes I have this paranoid feeling that my adviser doesn't actually care whether I even know what our project is about. When I simply ask for more to learn or read about relevant to our project, he does not give an answer. I've taken multiple upper-level and graduate physics courses at this point, so I feel like I should be able to contribute something at least. Should I think about switching to a different adviser? Is this a normal problem for undergraduates?
