The Mathematikum is a science museum, located in Gießen, Germany, which offers a huge variety of mathematical hands-on exhibits.

The museum is opened every day of the week, excluding Sunday and Monday.

The purpose of the Mathematikum is to let people of any age, gender and any qualification learn mathematics by personal experience, rather than teaching it using formulae or equations and hardly ever numbers and symbols.

Mathematical experiments include mirrors, a Leonardo bridge, soap films, and puzzles.
