ACES will gather ultra-precise data across at least ten observation windows, each lasting about 25 days during the ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

He called the slowing of time due to motion time dilation. Imagine you're standing ... the 1970s provided some pretty strong evidence: Atomic clocks are extremely accurate clocks that can measure ...

for an extra time dilation comparison. We’ve featured innumerable clocks over the years here at Hackaday, but among them have been a few based upon atomic standards. More than one has been used ...

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation corresponding to ...
