Temporary exhibition

Multidisciplinary exhibition presenting selected works by CERN researcher Michael Hoch, as well as the foundations of particle physics explained and related by CERN researcher Hans Peter Beck, from the Universities of Bern and Fribourg. 


The exhibition provides a historical overview and adds a local touch on the discovering of cosmic rays, where the physicist Albert Gockel from Fribourg established first hints in the balloon flights he undertook over a century ago. 

Experiments carried out at high altitudes, in balloons, airplanes and in high mountain stations, such as the Jungfraujoch and Gornergrat research stations, allowed researchers to detect radioactivity in the atmosphere and to conclude on the existence of cosmic radiation.

Contents of the exhibition :

  • Michael Hoch ’s works, artist and physicist

  • Scientific informations on the subject of cosmic rays and particle physics

  • A guide entitled ‘ Young Scientist Program ’ for visitors and school groups
