March 16th The Riddle will meet their Think Tank. This day project leader Karina van Dalen-Oskam and the three PhD candidates Andreas van Cranenburgh, Corina Koolen and Kim Jautze will present their latest results and the progress they made over the last four years. We are looking forward to meeting the Think Tank members and are sure we will benefit from their remarks in order to come as close as we can to solve the riddle.
