My son and I had a maths day yesterday, and I’d intended today to be in the ‘history/language’ category, but I managed to spot some maths nonetheless at the Gutenberg museum in Mainz with these fab eclipse pictures, a guide to using your sundial, and some interesting-looking geometric diagrams.

Also there’s definitely something going on with these stained glass windows in Mainz cathedral. What do you notice? What do you wonder?
