They concluded that the performance of their OFD system is sufficient to support an atomic reference with stability better than the commercially available cesium clock that has frequency ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

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 ...

The atomic clock provides initial accuracy of ±0.5 parts per billion (ppb), low frequency-drift performance under 0.9 ppb/month, and maximum temperature-induced errors below ±0.3 ppb.

The Onvis outdoor motion sensor, built with Thread technology and an IP66 rating, is made to work great in both areas. If you want to trigger HomeKit devices based on motion outside, read on to ...

Microchip Technology has introduced its second-generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), model SA65-LN. It features a lower profile height and operates in a wider temperature range, ...

The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight - the theoretical point of annihilation. That is one second closer than it was set last year. The Chicago-based ...

Over the last several years, researchers have shown that it is possible to design clocks 1,000 times more precise than the atomic clocks that the original definition of the second is based on ...

Winchester 21 Sharp Cartridge Review—Expert Tested Fortune favors the bold, they say, and Winchester's latest cartridge introduction is about as bold as it gets in the rifle-ammo world.

Graduate students Chuankun Zhang and Jack Doyle in the lab at JILA, a research institute at the University of Colorado at Boulder, where they and others are working toward a nuclear clock.

More While their nuclear clock is still a work in progress, once realized it could transform not only timekeeping but also the study of physics, even affecting how scientists investigate the ...
