Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State ...

Physicists in Germany have built the world's most accurate atomic clock. A team from the Physikalisch-Technische Bundesanstalt created a clock that works by measuring the vibration of ytterbium ions ...

An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a “fountain” of cesium atoms, according to a paper by ...

Here’s what you’ll learn when you read this story: Timekeeping has evolved greatly during humanity’s short time on Earth, and that legacy of metrological innovation is far from over. A new study from ...

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

Improvements in clocks are setting the stage for a redefinition of the second. This is an Inside Science story. (Inside Science) -- Earlier this year, in a nondescript lab at the National Institute of ...

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...

Travellers have relied on accurate timekeeping for navigation since the development of the marine chronometer in the eighteenth century. Galileo, Europe’s twenty-first century navigation system, also ...

(Bloomberg) — If time is money, precision in nanoseconds can be measured in millions of dollars. Shimadzu Corp, a Kyoto, Japan-based precision equipment maker, has started selling a clock which is ...
