Soon the most challenging physics competition of the year will be held again: PION (Project Interuniversitary Olympiad for Physics)! This year it will be organised by Marie Curie in Nijmegen. You can win tickets to the international olympiad PLANCKS when you do exceptionally good. If you think you are up to the task, or just want a nice day with other physicists, do not hesitate to register your team (four people maximum) now and astonish us with your skills on Februari 24th 2017!
