We had a really good time with you all in our Berlin talk. We thank Katja, Jan, Markus, Louise and their team for the dedicated organization and for creating a warm and inviting atmosphere for us all to be in! We also thank the LCB Foundation for its kind support. Last but not the least, we want to thank all old and new friends who made the way to our talk and engaged yourself by raising many interesting questions and comments. The evening will for sure stay unforgettable for many of us for a very long while!
