About a month ago, I went off with friends on a mystery weekend, and ended up in Bonn (friends willing to plan mystery weekends, and go along on mystery weekends are the best sort, in my opinion!). We went a gorgeous bike tour of the city, and eventually ended up at the University of Bonn’s Arithmeum. Museum of the history of calculating.
We had a great guide, who explained how complicated it had been to create a working adding machine, that would carry all the digits. It used to be complicated work.
These days we can whip out our phones and calculate what 15% off on those fabulous knitting needles will mean to our budgets.
As luck would have it, the Arithmeum (attached to the University Math Department) also had an art exhibit from their works inspired by discrete mathematics.
Absolutely gorgeous. Speaks to the knitter in me. Very much intarsia or mosaic-knitting…
