Surprisingly you offer to neither show, nor tell what happens... which leaves us with your statement: I can just imagine attempting logical measurements ... Luckily, those who practice the trade have skipped the part of imagining and just accomplish it instead. This gives a "glimpse" of what I mean, the above was vague ... http://www.newton.dep.anl.gov/askasc...9/phy99194.htm Given the reference (a painfully pretentious website with as much armchair theory offered as in this thread), you must have misspelled vogue. The forced argument (a strawman at that) of motion ceasing went out with fringe topped surries. Now THAT (motion? what motion?) is vague in the extreme given there are a considerable number of dynamics that occur at the 0°K atomic scale. Are we suppose that electrons in their orbits at 1°µK will collapse into the nucleus (permenantly frozen into inaction) with the final chilling tweak? What a larf! These akademik arguments only need the added stipulation that you have to exhibit an absolute zero beer cooler that will hold the temperature throughout the Super Bowl. 73's Richard Clark, KB7QHC |

From: http://www.calphysics.org/zpe.html "Zero-point energy is the energy that remains when all other energy is removed from a system. This behaviour is demonstrated by, for example, liquid helium. As the temperature is lowered to absolute zero, helium remains a liquid, rather than freezing to a solid, owing to the irremovable zero-point energy of its atomic motions." -- 73, Cecil http://www.w5dxp.com |

On the contrary, we have every reason to believe it acted differently before the first super nova.

un-misexpurgated: Things that don't exist generally act differently from things that do exist. The solution to the missing Weapons of Mass Destruction that failed making it into another Texan's speech this week. I suppose it got transliterated into a proposal: The dead need a better health care system. |

quoting Brett: Name me one instance where anyone has achieved taking a cesium atom to absolute zero ... Two Nobel prizes were won for doing this with Rubidium. Some may recall that I already cited that as the other frequency standard element (although rarely used as it is inferior to Cesium). 73's Richard Clark, KB7QHC |

Why is it always some weird, out of the way atom they play with
instead of a main-line, every day used sort of critter? Krypton. . . Cesium . . . What ever. Why not Oxygen? Carbon? Even good ol Iron?? Another thing, as it was explained to me, first the electrons are ghosts to begin with which pop in and out of existence at a whim. Second, if I had the nucleus of an atom in my hand, and it was the size of a medium orange, the closest electron would be some where around 38 miles away. . . `Lots of "Nothing" in between. So, when you get down to 0 Kelvin, that's where all the shaking around stops, well, it slows down enough to stop the harmonic vibration, but it also seems to me that the electrons quit popping in and out of existence then too. Hence the lack of unbalanced vibration of the missing, counter balancing electrons. (Much like missing a tire weight at 70 mph on the freeway or so I would believe.) SO if everything settles down at 0 "K" and starts working properly, why is it so damn hard to achieve? It seems to me that everything would try to achieve the balancing point, . . Equilibrium; Being that matter abhors a vacuum to begin with. There has GOT to be an antagonist stirring the pot somewhere from behind the scenes!! . . . Gravity?

Another thing, as it was explained to me, first the electrons are ghosts to begin with which pop in and out of existence at a whim. That was some explanation. It raises one of two questions. Did you understand it? Or did the explainer? it also seems to me that the electrons quit popping in and out of existence then too. This would seem to pin a no to each question above. SO if everything settles down at 0 "K" and starts working properly, why is it so damn hard to achieve? Does a 2 year-old ever settle down? Short of their already being asleep, why is that so hard to get them to bed? It seems to me that everything would try to achieve the balancing point, . . Equilibrium; Being that matter abhors a vacuum to begin with. There has GOT to be an antagonist stirring the pot somewhere from behind the scenes!! . . . Gravity? People do a fairly good job of gumming up the works. Heisenberg introduced us to the notion that when we bother to look, everything changes. A pyramid balanced on its point is in an equilibrium, but that is not the same as it being in its lowest energy state, also an equilibrium. Not all equals are equal (credit George Orwell). 73's Richard Clark, KB7QHC |
