Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems ...

An international team of researchers has, for the first time, coupled an atomic nucleus to an atomic clock to compare differences in their timekeeping frequencies.… The breakthrough promises to ...

This large atomic alarm clock can either be set on a tabletop or hung on your wall with the included mount. This battery-powered alarm clock requires three AAA batteries (which are not included ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall ...

This ability to compare distant optical atomic clocks is a step toward clock networks that could be used to make precise measurements such as characterizing Earth’s gravity and testing ...

Vector Atomic has launched a rack-mounted atomic clock. The company this week announced the launch of Evergreen-30, which it said is the world’s first fully integrated commercial optical atomic ...

At the heart of an atomic clock are, as the name suggests, atoms of a specific type. Now, physicists at the National University of Singapore (NUS) have found that lutetium atoms could make for ...

The atomic clock is a standardized unit of measurement that has been used since the 1950s to tell time and measure the Earth’s rotation, said Dennis McCarthy, retired director of time at the US ...

The actual device that measures that frequency is called the ‘comb,’ and it’s typically one of the largest components in a modern atomic clock. The Sussex researchers have developed a way to ...
