The WOL organises the Department Day of Mathematics, May 8th 16:00 - 18:00 in KBG Pangea. Here, we will introduce the new WOL. There will also be alumni to tell about the posibilities after your study. We will also see Michiel Schuijer, about the math behind music theory. After these talks, we invite you to drinks! The Department Day counts as a Caleidoscooplezing once (so not if you went last year and handed in a summary).
