Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

The world’s most accurate clock now belongs to researchers at the National Institute of Standards and Technology (NIST). Its new optical atomic clock, built around a single trapped aluminum ion, can ...

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...

The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In A Nutshell The world’s most precise clocks are changing how we understand ...

Tokyo, Japan - Resembling a squat, wide fridge, the world's most accurate clock just went on sale for $3.3 million in Japan on Wednesday. No, that's not a soda machine... it's a clock! And not just ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

Time dilation, a captivating concept embedded in Einstein’s theory of relativity, has been experimentally validated on Earth. With the use of ultra-precise clocks, scientists have been able to ...

The low-cost MCP7940M real-time clock/calendar IC includes a digital-trimming circuit that can compensate up to ±127 ppm for crystal error. The device is available ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
