The groundfloor of the Science Museum is full of technical and scientific objects which change our world in the last centuries and we find some mathematical objects (of course!). For example, we can see some slide rules: Fuller’s slide rule from 1890 (nr.25), Boucher circular rule from c.1885 (nr.26), a celluloid slide rule for triangle-mesh-reinforced concrete slabs from c.1912 (nr.27) and an engineer’s combination rule from c.1870 (nr.28).

We also find the calculating machines which became popular after 1850 among bookkeepers, astronomers and engineer like this Trinks Brunsviga (c.1908-1914):
