It won't spin on its own for 24 hours...
Uh... we all understand that Charles. The pendulum only swings for around two hours regardless of its length, or whether or not it has a motor attached. But in that two hours, the earth's rotation is clearly indicated by the fact that the plane of the pendulum's swing arc will have rotated (or appeared to) by 360º/12 and which is clearly visible. The only reason that museums use a motor to give it a "nudge" every couple of hours is so that some bloke doesn't have to stand by to do it with some complicated apparatus in order to keep the tourists happy. And most importantly, this motor is designed so as to not apply any rotational torque to the pendulum's suspension point.
You can see why wankers like this guy swallow the crap...
So insulting someone who's attempting to illustrate a simple scientific principal using only a relatively primitive apparatus is a "wanker" according to you?
Ad hominem attacks appear to be one of your favoured tools of debate
Charles. Which is what some people do when they're backed into a corner. It's a feeble argument.
He cant remember which way the earth is suppose to spin.
I have to agree with you, and it surprised and disappointed me too. Even grade school kids know this simple fact. The problem for him is that it opens the floodgates for people to claim that he really doesn't know what he's talking about, and even worse, that the rest of his claims could also be riddled with a similar lack of scientific knowledge.
Still, his explanation of the Foucault pendulum
is correct, despite his apparent lapse of knowledge of basic geophysics.
