The Germans are smokin' -- more timekeeping news
From
Physics World:
Germany sends optical-clock signal over nearly 1000 km
Physicists in Germany have sent a burst of light over a distance of 920 km down an optical fibre � with its frequency remaining stable to the 19th decimal place. As well as supporting the development of highly accurate "optical clocks", the breakthrough could also be used in a range of commercial and scientific applications including precision spectroscopy, geodesy and very-long-baseline astronomy.
Much more at the site.
This is very big -- astronomy just got a huge boost in resolution.
Set up a network of these puppies and you have a gravitational wave detector.
