For many years, scientists all around the world have been working towards this goal, now suddenly things are happening very fast: it was only in April that a team led by Prof Thorsten Schumm (TU Wien, ...

Each year for the past 78 years, the Bulletin of the Atomic Scientists has published a new Doomsday Clock, suggesting just how close – or far – humanity is to destroying itself. The next edition of ...

Wall clocks! Are they very accurate? Well, sometimes they are, and sometimes they lose minutes a day. If you’ve got one that needs calibrating, you might like this device from [Lauri Pirttiaho]. Most ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

The SKY63104/5/6 family of jitter attenuating clocks and SKY62101 clock generators are the industry’s first clock devices that can simultaneously generate Ethernet and PCI Express® (PCIe) spread ...

In a nod to history, the digital clock’s seconds indicator incorporates the British railway system’s renowned double arrow logo. By Susanne Fowler Reporting from London Train stations are known for ...

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...

The timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks. Reading time 2 minutes Meet the “nuclear” clock: a device that marks the ...
