"World In The Balance: The Historic Quest for an Absolute System of Measurement"
Robert Crease
Very well-written, this was a mostly (I got a little lost in the final third) interesting book on the birth and history of the metric system. There's so much about measurements that we take for granted, that I never even thought had origins or stories--but do. Enjoyable.
I'm also doing an experiment this week of thinking in terms of the metric system, inspired by this book. It's a lot more exciting to go 108 kph than 65 mph. #whatIreadin2017
