Science is international
"The generation of scientific insights is contingent upon discourse that is forthright, unfettered and international. It hinges on the interdisciplinary personal exchange between academic dis- ciplines, nations and cultures. The executive order signed by the President of the United States this past Friday is a sweeping discrimination of human beings based on their ethnicity and con- sequently also an act of aggression against the fundamental values of science. Hence, German Scientific Organizations are extremely concerned about the President’s executive order. It is not a justified tool to use in the necessary fight against terrorism and will gravely impair the international exchange that is of such critical importance for scientific collaboration."
