Scientists propose a new atomic clock experiment that could reveal whether time itself follows the strange rules of quantum ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could ...

Atomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

In advance of hurricane force winds moving into Colorado earlier this week, Xcel Energy preemptively shut off power to protect areas of the state from extreme fire danger. But due to the outage, time ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...

"How accurate does one second need to be?" Korean researchers are officially joining an international project to directly ...
