Stop reading bullshit internet and do experiments. The fact that they cannot tell the shape of earth with a pendulum just means that they do not know physics and just copy paste the same low level stuff without understanding a word. I am a 55 years old engineer. I know a bit more than Wikipedia man.
Discussion
Are pendulums primarily used to demonstrate motion or shape?
What does even means primarily used. They are primarily used as a time references in clocks.
The procession effect has more to do with the gyroscopic effect than the time of oscillation of the pendulum.
I mean was the experiment devised to determine motion or shape? It's not a difficult question.
Man in 1850 they didn't have the means to speak to someone on Internet on the other side of the planet and set an experiment of comparison of speed of motion and direction of rotation.
Do you understand how the pendulum set at different latitudes gives proof of shape or should we in 2025 still reference to and experiment of 200 years ago without the ability of using it for a bit more? We have planes now they had horses.
On a sphere the pendulum rotation is related to the position on the sphere. We now can and did test it and earth is a sphere unless the aliens generate hidden forces to steer the experiment results and make us believe. Why should they do that?
It's incredible how you can't answer a simple question.
I completely understand how shape is INFERRED from the presuppositions of the experiment, but that was never ever the point of the experiment.
Who cares we are engineers not philosophers or scientists. Stuff that works works. If it is elegant, nice or bad we do not care.
Okay, so you won't answer, presumably because you think I'm trying to gotcha you rather than have a discussion. Just to be clear, I haven't proposed anything obscure by claiming the experiment was devised to test motion.
What are your thoughts on the Allais effect?
Why are the results with these pendulums so inconsistent?
