Physicists Unveil World’s Most Precise Clocks
May 30th, 2013Via: MIT Technology Review:
Today, Andrew Ludlow at the National Institute of Standards and Technology in Boulder and a few buddies unveil the two most accurate clocks ever built. They say their new clocks can keep time with an unprecedented precision of one part in 10-18.
Ludlow and co put this in perspective: “A measurement at the 1018 fractional level is equivalent to specifying the age of the known universe to a precision of less than one second or Earth’s diameter to less than the width of an atom.”
