In a decade, your wristwatch will be thousands of times as accurate as it is today
Caltech Photonic Clock Technology
This watch's light-powered drive mechanism vibrates thousands of times as fast as quartz.
This optical clock technology, developed at the California Institute of Tech- nology, could make the most accurate watch available now seem as retrograde as a sundial. A laser pumps photons around the rim of a microscopic glass ring, causing it to swell and contract 80 million times per second.
