"But maybe to emphasize: walking to the conference one morning, in sunny NYC, I actually was thinking this. My colleagues and dear friends are to be found in many places of the world. That's one of the reasons to go to a conference. Even if one is tired and stressed out beforehand. You actually feel better and more energetic afterwards. And, talking with colleagues at university in other subjects, I know this is not self evident. So much of "positioning" and quarrels. Let's take care of the good sprit and open dialogue!"  Eva Georgii-Hemming
