CartesianSeminar

The Potsdam Cartesian Seminar is an open topic weekly seminar that was started in 2000 by Rupert Klein and Cezar Ionescu at the Potsdam Institute for Climate Impact Research and is located at the Institute of Computer Science of the University of Potsdam since 2014. Guided by the rules René Descartes formulated in his “Discours de la méthode” we aim for a thorough understanding of the texts we read.
