In the future, optical atomic clocks are expected to measure time 40,000 times more accurately than established atomic clocks. As part of the ISABELLA project, a consortium of industry and research ...
Pictures of the components used in making an atomic clock. The ion trap (left image) holds the clock in place. The optical/laser apparatus (right images) measures the clock’s frequency. Fukuoka, Japan ...
"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, ...
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.

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
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 ...
