The MiMa, museum for minerals and mathematics in Oberwolfach, invites you to take a look at the wonderful world of minerals and mathematics in a way you have perhaps never done before. The MiMa museum does not only host the one-of-a-kind minerals of the Black Forest region or provides insights into mathematical theories, it especially presents the connection between minerals and mathematics: interactive installations let you understand symmetry and crystallography in a playful way.
