400 years of mechanical calculating
22 September, on the Groenenborger campus of the University of Antwerp, at 16:00 in auditorium G.T.105
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.
The opening symposium will take place on 22 September, on the Groenenborger campus of the University of Antwerp, at 16:00 in auditorium G.T.105.
You are cordially invited, and register via: https://forms.office.com/e/tvypJvkLxz
