Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

The cold-atom clock exceeds them all in accuracy, according to Liu. Scientists attribute its accuracy to the microgravity environment in space, as well as the coldness of the atoms it uses.

The most accurate clock in the universe. By Yang Chunxue and Yu Fei | China Daily | Updated: 2016-11-07 08:04.

Physicists have built the most accurate clock ever: one that gains or loses only one second every 40 billion years 1. Alexander Aeppli at the research institute JILA in Boulder, Colorado, and his ...

Accuracy may come at a cost. Entropy — or disorder — is created every time a clock ticks. Now scientists working with a tiny clock have proven a simple relationship: The more accurate a clock ...

Clocks release disorder, or entropy, as they tick. A new experiment shows that, for one tiny clock, the more accurate the clock, the more disorder it generates.

An Even More Accurate Atomic Clock Scientists have unveiled an atomic clock that sets new records in timekeeping — it could run 5 billion years without gaining or losing a second. That sort of ...

Most accurate space clock to launch – and count down to destruction. A network of Earth's best clocks will be synchronised with the most accurate one ever sent into space.

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only ...

Here’s what you’ll learn when you read this story: Timekeeping has evolved greatly during humanity’s short time on Earth, and that legacy of metrological innovation is far from over. A new study from ...

Enslaving a clock to another more accurate standard does not make the clock itself more accurate. And as long as that clock is enslaved, it won’t drift a second, not even in “158 million years ...
