Nerd mode activated, Greg woke Katelyn up early to go see the Museum of Science. Actually, it was pretty cool with all sorts of instruments and telescopes and globes and random stuff used by scientists and ‘mathematicians’ from the tenth century onward. At that time, mathematics was pretty much synonymous with astronomy, so a lot of astrolabes and stuff. Other highlights include mechanical calculators, early electrical devices, and several of Galileo’s gravity-measuring machines (and his middle finger, weirdly on display in a jar).
