On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

STATEN ISLAND, N.Y. — It’s almost time to push our clocks ahead and bring on the sunnier evenings of spring. Even though today most smartphones, laptops and smartwatches rely on GPS satellites and ...

Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...

From sundials to atomic clocks, our understanding of time has become a lot more accurate as technological developments allowed us to measure it more precisely. Much more than helping us arrive on time ...

In a perspective article recurrently published in the National Science Review, Dr Xin Tong (Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences) and his ...
