I will be starting a Master's program in the Fall for Physics. I would like to START the search for a master's thesis, but have no idea where to begin. Here is the reason: When I start researching a topic I think may be interesting the physics is so over my head I have no idea what's going on. Here's my question: How are you supposed to understand the "big picture" of a research topic if you have no idea what they are talking about ever? Any advice?
