Physicists at the Joint Institute for Laboratory Astrophysics have developed a new atomic clock that is so accurate, it will not lose a second of time in more than 200 million years. That makes the ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

The timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks. Reading time 2 minutes Meet the “nuclear” clock: a device that marks the ...

Ekkehard Peik is a clock-maker. But instead of spending his days looking at tiny cogs and springs through a magnifying glass, the tools of his trade are powerful lasers, wires and, occasionally, ...

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 ...
