Arithmeum

It was founded in 2008 by the director of the institute, Bernhard Korte, who contributed his private collection of calculating machines.

The building's steel-glass facade – located at Lennéstrasse 2 – is meant to represent the "transparency of science".

The permanent exhibit "Calculating in Olden and Modern Times" (German: Rechnen Einst und Heute) shows the progression of mechanical calculating machines through 1,200 pieces.

It holds the very large (4,000 pieces), IJzebrand Schuitema (1929–2013) 400 year collection of slide rules.

[1][2] There are also exhibits on very-large-scale integrated (VLSI) logic chips, historical arithmetic books dating back to Johannes Gutenberg's times, and the relationship between art and science.
