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 ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

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 ...

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The ongoing race to create the next generation of hyperaccurate ...

Craig has worked in automotive media for nearly 20 years, producing content for publications ranging from Autoline and AutoGuide to Roadshow by CNET and EV Pulse. Aside from writing, he’s also ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

(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 ...

In the early 19th century, as the sun moved across Britain from east to west, people set their clocks to local mean time, so that noon in Greenwich would occur about 16½ minutes before noon in ...
