Hi everyone, If you haven't already, you might want to check out the first part of the documentary "Precision: the measure of all things". It's about the measurement of time and length, featuring the topic of sundials. There's an interesting theory about how the day got split into 12 hours because this number is highly divisible (but why not 60?). I just watched it on Da Vinci Learning.
