As the rain eased we headed out and cut through an indoor market. Lots of lovely sights and smells there so we resolved to come back for lunch. A little street weaving and we were at the History of Science museum. It’s fair to say there a number of exhibits that were things I hadn’t heard of and didn’t understand but the range was very wide and there was plenty to keep me entertained plus new exhibits still planned. It was a small museum but a pretty wide collection of instruments and exhibits (typhoid vaccination needles, a wax model of facial nerves, cameras, orreries, sextants, clocks, telescopes, slide rules). The popular choice for a scientific instrument seems to have been brass for several hundred years.
