New near-zero-temperature atomic clock aims to redefine how precisely we measure time
Today’s state-of-the-art optical clocks offer accuracy to 18 decimal places, which is roughly equivalent to measuring the ...
A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of ...
We present the frequency steering of two continuously-running hydrogen masers using NPL's state-of-the-art optical atomic clocks. The resulting optically steered time scales are aligned with UTC(NPL) ...
(CNN) — No, I did not prepare for the end of Daylight Saving Time this past weekend, when most US states set clocks back an hour. Sunrise and sunset now come an hour earlier, despite my protestations.
Skies will remain partly cloudy overnight, with seasonably chilly temps around 40. The water war Trump hasn’t blown up Florida murder suspect gets short sentence after attorney general intervenes ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...
