Last month, a consortium of 69 scientists from across Europe and Japan completed the largest and most coordinated comparison ...

In the final analysis, by showing that 10 heterogenous clocks across three continents could agree with each other to within a ...

So far, the shortest day ever recorded was July 5, 2024, when Earth rotated 1.66 milliseconds faster than usual. This year, ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

In a nutshell Scientists connected 10 ultra-precise atomic clocks across six countries in the largest coordinated timekeeping experiment ever conducted While many clocks agreed to extraordinary ...

Its clock signals will be transmitted back to Earth using two distinct methods, which will then be matched against ground-based atomic clocks to catch even the tiniest drift. The most precise ...

Atomic clocks use this technique to measure the transition frequency of atoms so precisely that they become standards for defining the second.

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

Multi-Ion Optical Atomic Clock Takes A Step Towards Changing The Definition Of A Second The breakthrough has applications from metrology to dealing with the consequences of climate change.

A clock is a model of the change that we’re actually interested in. The atomic clock, which for ever ripped time from its solar embrace, is the ultimate abstraction.
