https://nextcloud.projectftm.com/index.php/s/gravitycompare https://nextcloud.projectftm.com/index.php/s/gravitycompare that is really impressive, the 100 year old data compared to recent data. i'm still amused there's no real explanation of how it works. Like, can i do this with three X 9-DOF sensors in a box? you don't need light or film, you can use a TCO for accuracy in timing... I don't know why it keeps saying 3 pendulums, but a pair, but a "virtual third pendulum". but what this is, is an analog computer, right?
