NIST Unveils Chip-scale Atomic Clock

Posted by CmdrTaco on from the and-it-fits-in-the-oh-never-mind dept.

grumling writes "The heart of a minuscule atomic clock, believed to be 100 times smaller than any other atomic clock has been demonstrated by scientists at the Commerce Department's National Institute of Standards and Technology (NIST), opening the door to atomically precise timekeeping in portable, battery-powered devices for secure wireless communications, more precise navigation and other applications.

    There will ALWAYS be a need for an outside reference time source.

    Whilst the device will keep track of time with an accuracy of 1 second in 300 years, what it can't do is keep time without power.

    The effect means a video recorder still shows 00:00, just a lot more accurately than before.
