Doc, and Friends, You are scholar/s and gentlemen! There is now one slightly less ignorant :approve:person walking/floating this earth. I am grateful for the fine explanations and your amazing quantity of your patience with me. It would take me months to go through all the books necessary to...

Doc, You say that the: I assume you say this because water is incompressible, thus the pressure on one selected volume of water is the same as is on all the rest. How do you then explain the pressure difference due to the weight of the water at different depths. Surely the pressure of...

With all due respect, But if gravity hasn't changed, and buoyancy hasn't changed and if mass and volume of the object hasn't changed then according to the math acceleration will also be constant. But there WILL BE ACCELERATION nevertheless. What I do not understand is: How is it possible for...

Gentlemen, forgive my stupidity, but I really want to understand this correctly. If the two objects have the same volume and mass - and one is wide and flat (like the surface dwelling fish) and the other is long and thin and vertical: according to r*g*(delta h) the long thin vertical one would...

Thank you Bill & Doc, So if I understand this correctly, the sphere can theoretically contain vacuum and still rise simply based on its m/v ratio with respect to water? It should rise even faster since gas has some added weight? With regards to r*g*(delta h): Does this mean that if I had a...

May I suggest that before we attempt to store & retrieve data, possibly we should try to store energy in a crystal. Technically that has already been accomplished in devices such as Ruby lasers. Ruby is a crystal, and if the two end-mirrors were not polished to be semi-permeable (so as to let...

Dear Friends, I have a problem that has been driving me nuts for months now, and I am hoping you guys can help. I need to understand whether: 1. The Force with which a hollow, buoyant Steel Sphere is propelled upwards from under water at significant depth changes as the sphere ascends to...
