The European Space Agency (ESA) is getting ready for the launch of an atomic clock system that aims to validate elements of Einstein’s theory of general relativity but could have implications ...

ESA's Atomic Clock Ensemble in Space (ACES) has arrived at NASA's Kennedy Space Center in Florida, United States. This cutting-edge European experiment will test fundamental physics from the ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

【Upgraded Big Screen Display】- Experience the luxury of a 5.5" High Resolution Digital Alarm Clock that spells out the time, date, and temperature clearly. The illuminated LED digits ensure ...

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 ...

Will you mail me a print copy of the Bulletin of the Atomic Scientists? Expand No, the Bulletin of the Atomic Scientists magazine is digital-only and has been since 2008. We do not print physical ...

Normally, these spins quickly lose coherence when they interact with other particles or absorb certain types of light, which limits their usefulness in technologies like quantum sensors or atomic ...
