The conducts a remarkable amount of excellent interdisciplinary research within eight groups and collaborating internal and external research institutions.

2 The conducts a remarkable amount of excellent interdisciplinary research within eight groups and collaborating internal and external research institutions. With this calendar, we invite you once more to enjoy some of the fascinating images arising from the broad spectrum of theoretical, numerical and experimental research efforts conducted at the CSI over the past year. Thanks to all those who have contributed their images and we wish you all a successful and prosperous 2013.
