U.S. physicists have made a clock so accurate it will neither gain nor lose even a second in more than 200 million years, a finding sure to please even the most punctually minded. The clock, described ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Stochastic watch: The clock in the experiment consists of a pair of quantum dots coupled by a thin tunnelling barrier. The clock “ticks” whenever an electron tunnels from one side of the system to the ...

Heralding a new age of terrific timekeeping, physicists have unveiled an experimental strontium atomic clock that has set new world records for both precision and stability -- key metrics for the ...

Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out ...

The ability to accurately measure a second in time is at the heart of many essential technologies; the most recognizable may be the Global Positioning System (GPS). In a paper accepted for publication ...
