@johncarlosbaez@mathstodon.xyz @morgaelyn@bolha.us Presumably sundials only work at specific lattitude? The Chinese ones can work anywhere, you just have to tilt it differently https://commons.wikimedia.org/wiki/File:Beijing_sundial.jpg

@liuyao@mathstodon.xyz - I'm not sure how flexible sundial are, but I imagine traditionally people would build sundials near where they were used. @morgaelyn@bolha.us
