Title of paper: “Using a MEMS gyroscope to measure the Earth’s rotation for gyrocompassing applications”
Even better, Foucault invented a modern version of the gyroscope (and gave it the name) to demonstrate the Earth’s rotation in a simpler manner than the pendulum.
ETA:
The gyroscope doesn’t have to be particularly sensitive. But it does have to be good enough, i.e. relatively low friction, not to stop spinning before the rotation of the earth can be demonstrated.
Thanks. That’s what I thought. I just wanted some confirmation.
There are standard surveying instruments sold that determine north this way.
There is a video by a flat-earther wherein he can’t understand how a gyroscope deflects 15 degrees per hour.
That shouldn’t be a problem for them. A flat earth could still rotate once a day.
The real test is whether the tilt of the rotational axis is different at different latitudes.
