Events Calendar
400 years of mechanical calculating
22 September 2023 to 6 September 2024, on the Groenenborger campus of the University of Antwerp, Hall T.
To mark the 400th anniversary of Wilhelm Schickard's first calculator, a number of colleagues from the Faculty of Applied Engineering joined forces to put together an exhibition on "400 years of mechanical arithmetic". This small but fine exhibition includes replicas of the Schickard and Leibniz machines, and numerous other highlights from the history of mechanical arithmetic.
We will again have a stand at the International Collectors Fair in Utrecht, Netherlands. This is the largest fair of its kind in Europe and caters to design, antiques, curios, in short anything collectable.
