Now, I do constantly worry about my understanding of such things; and, if they are in error will seek to "update" them. But, the example you just gave me is about the weakest and most worrisome I have seen ... What example? Are you saying you don't believe that is the definition of the second since 1967 or that you don't understand the definition?

In 1994, the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin). In 2003, researchers at MIT eclipsed this with a new record of 450 pK (0.45 nK)." I don't suppose it ever occured to you that a practical hardware implementation would correct for the actual temperature? snip nonsense Since you seem to like wikipedia: http://en.wikipedia.org/wiki/Second Hmmm, looks like they got their definition for the second the same place I did. -- Jim Pennino Remove .spam.sux to reply. |

I thought that would have been clear from the way our "discussion" was going. Non sequitur.

Aliens watching first runs of 50s soap operas ("The Secret Storm" in this case) would undoubtedly have naming problems. This is not a technical problem; it is a cultural one. 73's Richard Clark, KB7QHC Again, I may have misunderstood "Old Al" along then! If that cesium atom no longer obeys your "10,214,000,000,000,000 oscillations"--"LAW", then perhaps 1,111,100 cps no longer obeys the "cps law" either. And, indeed, 1.1111 Mhz is no longer what we see at all!!! Of course, the above must be wrong. ET did manage to call home and apparently there were able to agree on the same freq. (sure would have liked to have taken a look at "Ole ETs'" watch ...) Warmest regards, JS I think that astronomers have made sufficient spectroscopic observations and measurements to firmly establish that physical phenomina are constant across the universe. Other dimensions may have different measurements but they are constant in this one. Dave N |

Now, perhaps we hit the real crux of this matter. You say "practical hardware implementation", I say "guess!" Warmest regards, JS The "SECOND" is an arbitrary measurement of duration. It has been defined with reference to specific measurements of a particular isotope of CESIUM under specific conditions. That those specific conditions may or may not be obtainable utilizing present technology is of no moment. Adjustments to the best obtainable results are made all the time in other areas. For instance the GRAM, the METER and the DEGREE. All these units are defined and approximated in real life. The only place where you can obtain absolutes is in conversion factors: 1 inch equals 2.54 centimeters, 1 degree Celsius (and it's derivatives: centigrade and kelvin) equal 1.8 degrees Fahrenheit. The degree Fahrenheit is determined by measuring the lowest temperature liquid water can reach and the boiling point of the same water. The upshot of all this is that everything in modern science is based on these and many other values. They all seem to work. At least until you get into quantum mechanics, which is another thread.

Seconds may be a different length in that far-far-away place. After all, the length of a second is relative to velocity so cycles/second are also relative, i.e. there is more than one way to accomplish a red shift. 1. changing cycles divided by fixed seconds. 2. Fixed cycles divided by changing cycles. 3. changing cycles divided by changing seconds. Now, like that told Virgina O'Hanlon about Santa Claus--if the NEW YORK TIMES said it, it must be true--or, perhaps the editor was mistaken?; I must admit--if Einstein said it, it must be true! half-smirk Einstein also said, "God doesn't roll dice." One of the quantum physicists responded, "Not only does God roll dice, but he rolls them in the dark." :-) -- 73, Cecil http://www.w5dxp.com |

What you just stated, the bible does indeed state, on a few different references (and NO, I DON'T know the bible scripture and verse--I am Catholic grin I drink AND smoke.) One such reference goes to making the point that all the names of the people to be "saved" are already listed in the book of life ... I think of this, like this, our universe is nothing more than a "burnt cd", and we are just a translation of the data existing on that cd. Much like watching a movie on cd ... who knows, maybe God enjoys this movie ... just no accounting for taste. Now I don't put a lot of probability in such--but hey, maybe you are right ...

Not to worry. Any relativistic motion on our part will only effect the clocks in the other reference frames.

I can prove that seconds are getting shorter. It takes me many more seconds to run 100 yards than it once did. I'm pretty sure that first second after the Big Bang wasn't anywhere near the length of a second now. -- 73, Cecil http://www.w5dxp.com |
