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 ...

coupled an atomic nucleus to an atomic clock to compare differences in their timekeeping frequencies.… The breakthrough promises to ease the development of the next generation of ultra-precise ...

Size: 5 x 6.45 inches; Time zones: 7; 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 ...

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 ...

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 ...

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 ...

If physicists can build them, nuclear clocks would be a brand-new type of clock, one that would keep time based on the physics of atoms’ hearts. Today’s most precise clocks, called atomic ...

Images and Video Ultraprecise Atomic Clock Network on the Hunt for Dark Matter Arabsat-6A in Photos: SpaceX's Amazing Falcon Heavy Triple Rocket Landing Michael Wall is a Senior Space Writer with ...

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 ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.
