As a graduate student, is it important to attend conferences? And I don't mean here playing the role of the speaker. I mean simply attending a conference. If yes, why is it important? I sometimes run across CVs in Physics, some of which include conferences attended. Is this important to list? One last thing, does any of you have an idea about an important conference that will be taking place in Europe during the upcoming year 2014 - or at least what important organizations should I be seeking their conferences. Thank you.
