Hi all! I often hear that the most important part of conferences is getting to know people personally, and all that. But how do you actually do that? Is it common for an average grad student to pull some professor by his sleeve and say "hey, I'm working on something remotely connected to your research, please hear me out" ? And when are you supposed to do that - after the lecture ends, or during the coffee time? Or does your advisor have to introduce you to somebody? Or am I completely wrong about all this? (Just haven't been to international conferences yet) What do you think?
