Hey all, I've been accepted to an awesome internship at a national lab this summer. The funding is excellent, the location is close, and my mentor seems excited for me to get started. He recently sent me a lot of documentation detailing the project and the instruments I'll be working with. Not only do I have virtually no experience with experimental physics, though, but I can't seem to make heads or tails out of the documents. He said that he is more than happy to answer any questions I may have, however I can't even make out enough of the documentation (papers on the subject, technical specifications of instruments, etc.) in order to ask intelligible questions. Although my professors who helped me apply to the program wrote outstanding recommendations, I'm beginning to wonder if maybe they were a little bit too outstanding and that I'm way out of my league here. I realize that this is an internship for undergraduates and that it will definitely be a learning experience, and that they knew that when they took me on. However, I can't help but feel as though I will slow them down tremendously and be completely useless in the meantime. I am very excited to take this position, but I honestly can't help but feel like there might be someone more well-suited for the job. Thoughts?
