Flat Earth Debate / Re: Absolute Proof the Earth Rotates
« on: March 23, 2014, 10:43:59 PM »
The pendulum swings in a straight plane, and we know there is no force available to make the pendulum rotate (no magnets, remember!), then it must be the earth that spins underneath it.
Firstly, it's interesting (well, not really LOL) that some flat earthers think that somehow, a magnetic force acting in the plane of the swing arc can induce any force perpendicular to that swing arc. It shows a surprising lack of understanding of both the principles and purpose (in this scenario) of magnetism, and the principles of force and motion.
Secondly, a few flat earthers can't seem to comprehend that it's the building rotating under the pendulum, and not the pendulum "rotating" above the floor of the building. Mental block?
And I'm just as guilty as others here, but how on earth(!) did we spend so much time talking about magnets—when in fact they have nothing to do with the principle of the Foucault pendulum?
Yea it's unbelievable. I, like you no doubt, have moments where I think this forum is one giant piss-take, because surely people can't be this ignorant/thick-headed.
Absolutely right about the affect of magnets, or complete lack thereof, on the pendulums rotation. I can see perhaps the quote from me was poorly worded, as I seem to suggest that magnets could affect the pendulum in the way FE's suggest. I should have said there is no longer any possible excuse for its rotation now that magnets are out of the question.
So far, this just about sums up the FE's argument about the Foucault pendulum: It's not rotating because it goes against my (flat) world view.
FE's love circular logic- seemingly, it's the only logic they adhere to in the first place.
