Where I work we have several cesium clocks to measure time dialation and distortion (Mainly. They are used for loads of other things as well). They are used to measure incredibly small discrepancies between two synced clocks.

These clocks have to accurate. Infact, nearly damned perfect or you'll get an incorrect, or worse yet, wrong result.

This is great news as our most accurate (and expensive!) cesium clocks will no longer be good enough for the job in about 10 years.]]>Jul 17th 2006 7:17AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 7:28AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 7:43AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 8:10AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/
Sorry, incorrect should of course be inaccurate. But I didn't need to tell you that though, did I?]]>Jul 17th 2006 8:24AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 8:29AMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/
Measurements in laser technology require the use of femtoseconds (10 to the negative 15th power), which are a millionth of a ns.

And if you are a photon researcher you need to make measure in attoseconds (10 to the negative 18th power), which are a quintillionth of a second.]]>Jul 17th 2006 1:03PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 1:10PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 1:21PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Jul 17th 2006 2:15PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://blogs.zdnet.com/emergingtech/?p=293 )]]>Jul 17th 2006 9:09PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/Actually they have GPS technology that is accurate to within 1 cm. They use a technique called RKP, Relative Kinematic Positioning, to correct GPS error to within 1-10 cm. I don't know of, and would highly doubt it's availiblity to the public....yet.]]>Jul 18th 2006 1:07PMhttp://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/http://www.engadget.com/2006/07/17/nists-new-even-more-precise-atomic-clock/
Also, take into account that any experimental evidence of physical theories, be it quantum mechanics, relativity, or M-theory (OK, potential evidence too, especially at the quantum level, is only proven by certain margin of error, which happens to be the most accurate margin of error in any scientific theory, for quantum mechanics, due to quantum uncertainty. This minute, almost non-existent margin of error could get even smaller with these advances.]]>Jul 20th 2006 8:48AM
