The Alliance of Science Organisations is celebrating the constitutional law, which has been protecting the freedom of science for 70 years with a nationwide campaign. With contributions to debates, discussion events, lectures, a mini podcast and a series of interviews on the topic of freedom of science, the campaign aims to support free research and critically examine freedom of science: How do scientists deal with this freedom? Where does science have to explain itself more? Where is freedom endangered and where does it reach ethical limits? All information about the campaign and the events can be found at wissenschaftsfreiheit.de (only in German).
