First: qeistkiesel. Thank you for your courteous replies and interest. I am glad you have appreciated the point of the satellite article. It does...
This is cleverly worded, but misleads the reader. There *are* such physicists, including most physics-textbook writers, reviewers, and referees....
You are right. What NASA scientists did was only vaguely related to Centre of Mass. However, interestingly NASA and other scientists currently...
Once again someone has blurred several different concepts together. You have confused the Centre of Mass Theorem (CMT) with the Sphere Theorem (ST)....
Looks like a valid and worthwhile result to me, in the context of proving that Newtonian Gravitation predicts gravity waves, and so the existance of...
How can a scientific discussion be pointless, if a dozen people participated, and there were 300 viewings of its contents? At least a few people...
The thread is about the failure of the Centre of Mass Theorem. It is not at all hypocritical or suspicious to use the Centre of Mass Theorem in...
Could it be that I know too much?
The problems of using Satellites, even with the latest equipment and theoretical advances should be clear to you after reading this:
I am stunned that you seem to have missed that the easiest way to calculate the force from the two halves of the sphere is to simply use the...
I usually answer particle entanglement by inspection, gently collapsing the wave function.
One thing I am willing to say with confidence at this time is that the Gravitational Constant is calculated from careful experiments close to the...
Okay lets go slowly and carefully: (1) The Centre of Mass theorem makes the claim that an object acts as if all its mass is concentrated at the...
Surely a simpler way to sort out the issue is to talk about how you would later compare the clocks. It won't really matter if one clock slows down...
Yes this is quite true: there is a variety of interesting alloys, especially 'steels' that are deliberately made not to interact with magnetic...
Yes, thank you. And this point is both interesting and important if our goal is to understand and model actual physical cases. The effects of...
Case 2: Vertical Barbell - (= Sphere split horizontally on a plane at the x-axis) [IMG] Consider a barbell made of two equal uniform...
Here is the first diagram for this argument: [IMG] ( I'll try to explain the diagram in words...a horizontal barbell lies on the x-axis at...
That's interesting: A real physicist was polite and willing to discuss details of the problem, and ended up agreeing with me on the essential...
Thank you for your interest and courteous responses. It is refreshing not to get flamed by some 19 year old who thinks he knows everything....
