The role of CERN in science diplomacy and in international research cooperation

CERN has put open science into practice for more than 70 years while advancing scientifc exploration on the global scale. CERN was imagined in post-war Europe and built on the principle of science for peace. The success of CERN, its complex scientific facilities for fundamental physics, and its strong support for international collaborations both large and small are a tribute to its original convention which states: "The Organization shall have no concern with work for military requirements and the results of its experimental and theoretical work shall be published or otherwise made generally available." Today CERN has 25 Member States and hosts a community of more than 17 thousand people from nearly 100 countries from around the world. In the world of today, these same principles of open science and science for peace enable CERN scientist to make connections and build trust that can lead to improved relations between nations.
