  • lol unprecedented? The entire country of LA would not exist without the early-LA government buying up water rights in the eastern sierras to pipe to LA, and then telling the local farmers there they were shit outta luck the first time drought hit.

    If anyone is interested in Western US water rights - Cadillac Desert by Marc Reisner is a great book. I usually recommend at least the first quarter of it, as it gets pretty dry and repetitive in the second half. But the first couple chapters talk about the first expedition down the Colorado River and early water rights, which was super interesting. Second half of the book mostly goes over large water projects like dams and aquaducts.



  • Earth’s natural satellite can serve as a valuable research partner in measuring the sun’s oblateness. This is due to a phenomenon known as “Baily’s beads,” which are the tiny flashes of light during an eclipse that occur as solar light passes over the moon’s rugged terrain of craters, hills, and valleys. Since satellite imagery has helped produce extremely detailed mappings of lunar topography, experts can match Baily’s beads to the moon’s features as it passes in front of the sun.

    The way I’m guessing this works is: Baily’s beads will be detectable on shitty cameras since they will be distinct flashes of light, and since we have very detailed information of the moon’s topography they can determine information on the sun based on your phone’s location and the timing of the flashes of light.

    And if that is how it works, that is fuckin rad. A+ science.
