    I’ve considered it before, but maybe I should look into it a bit more concertedly! Every time I’ve gone into a doctor for a long term condition, they inevitably tell me to take B12 for 2 months and come back, and by that time I’ve usually lost my motivation for doing something about it. 😆













  • We think sand clocks have only been in use since the middle ages, and the reason they were invented is pretty interesting. (At least in Europe; I’ve looked into this before and couldn’t find any other sources, but I may just not have looked hard enough).

    For reasonably accurate time keeping, people had been using water clocks since at least the 16th century BCE. Basically the same idea as a sand clock, but water, which was slightly easier to feed into a reservoir. We don’t think sand clocks really saw any use until the 13th or 14th century CE. Mostly, people needed to keep more accurate time on ships as oceanic voyages became more common, but the movement of the vessel messed up a water clock too badly to be useful, and pendulums had the same problem. So, enter a sand clock! Basically the same idea as a water clock, but way less prone to errors from the ship’s movement.

    (edit: some spelling)

    Oh, definitely. It’s also worth noting that he definitely wasn’t a geologist, despite having an interest in it. I was mostly just mentioning it because there were theories trying to explain the similarities across landmasses before plate tectonics. We may not always be right about why, but we’re really good at noticing stuff like that (even when it doesn’t mean anything).

    FWIW, seconded. These look basically identical the grape hyacinth bulbs in my yard.

    You can check by making a tea out of them. I don’t recommend drinking it (it’s mostly just “green” flavor), but it works as a pH indicator. If you add a bit of lemon juice, it should turn pink!
