Sorry I don't have a reference for you but this is what I remember from school. Yes, if a body is inserted in a field, which is itself a convention designed around particular forces, then that body must obey the laws associated with that field. The effects of these laws may be masked by...

Going to school Gentlemen; Listening to you talk is better than any course I've had at University,(peer to my best course in Quantum ). Thanks

More precisely I didn't mean by "jump to weirdness" simply being non-linear but more strictly the idea of mathematical discontinuity. The old delta epsilon argument: there is no point in time that we can get arbitrarily close to and find all the material of a phase transition in one state...

Refreshing Thank you for your clear headed, honest, not bound by the party line comments.

weirdness I agree with your assessment of how we see things,( judge whether it is weird or not), but the point was "jump" to weirdness. I would like to believe that nature tends to be more continuous rather than not. For example, how evolution worked,(is working), or how a ball travels in...

Whoa ego! No, Wrong. I realize you have to have a least modest of confidence to tackle this mathematics but perhaps you should examine your way of expressing your ideas. Just because you put things in capital, by the way the rules say that is "shouting" and therefore rude, it isn't...

Time for alarm I have no illusions,(not too many). I know that I am a fiesty third-grader in the ring with Mike Tyson but one hopes that he would be too embarrassed to take my head off. But I am mildly alarmed that Physics has turned into a new form of mathematics(extremely wide ranging and...

Testie professionals I am a little surprised how sensitive the physicists are to a little questioning of what they so thoroughly believe in. I don't find Buckeye's questions particularly aggressive. As a matter of fact I think similarly sometimes about how physicist attack and explain...

You forgot the column of air that was originally on top of the scale that is now gone. It weighs something too. Are you saying its too light to register on the scale?

Wait a second. On second thought, I'm not so sure about your assertion about the rock. Granted, as the rock falls to the bottom it is falling through water that has pressure in all directions equal to the column of water over it(Bernoulli) but once the rock is flat on the sea bottom then...

You're right. Thanks for the correction. But since there is no fluid around to push up at that rate can't we now safely say there is no bouyancy?-- no force pushing up? Since in your example the water is still trying to push its way under the rock but if no water is there no upward force can...

Let me repeat. There is no bouyancy force at all unless the density of the object, in this case the pineapple is less than the fluid that is inside of, this case air and then vacuum. Your equation above is subtracting from the weight of the pineapple as if there is a bouyancy force but there is...

If nature becomes as you are suggesting then "all bets are off" and we can forget the idea of science as we know it.

Sorry, I meant to say the density of the fluid is greater than the object being bouyed up. And the object is therefore less dense than the fluid.

To bouy or not to bouy First, I think two of the answer are just about the same thing said a little differently. (b&d) Secondly, the idea of buoyancy assumes the density of the thing that the fluid is pushing up is higher,(or should I say greater than), than the fluid's. In this case, it...
