Scientists Found an Entirely New Way to Measure Time

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

Optical atomic clocks poised to redefine how the world measures seconds

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

Innovative optical atomic clock could combine single-ion accuracy with multi-ion stability

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 ...
