This will be the last two-week session of Chemikum Marburg at its old place. In winter, the Chemikum Marburg will move to very central premises in "Bahnhofstraße" near to Marburg Central Station to open daily from 2012. Lectures and experiments are in German language (English translation for the new Chemikum in "Bahnhofstraße" is in close examination). Further information is given on the homepage: http://www.uni-marburg.de/fb15/chemikum. Please register exclusively via telephone call.
