Jochen was a brilliant and visionary scientist who inspired me and so many others. His creativity blew my mind more than once and his generous advice early on in my career was extremely useful. How lucky I feel to have met him.
With deep sadness, we share that Prof. Jochen Guck, Director at the Max Planck Institute for the Science of Light passed away on October 3. His visionary work bridged physics and medicine. We have lost a brilliant scientist and dear friend.

Slowly and tediously, even the rich and powerful can be taken down in functional democracies. This is the third conviction for Sarkozy (and his acolytes). This should encourage other democracies in difficult situations to keep hoping for justice to prevail.
