Advancements in nuclear clocks using thorium-229 promise to redefine precision timekeeping, revolutionising technology.

The most precise clocks in the world will lose only one second every 300 billion years—and someday they might fit in your pocket.

Back in April, the White House issued a challenge to scientists to develop a lunar time standard to support future moon bases and increase traffic between ...

The Doomsday Clock is a global warning of how close we are to the apocalypse. This is what you need to know before it reaches ...

Time is vital to the functioning of our everyday lives: from the watches on our wrists to the GPS systems in our phones.

The method merges state-of-the-art atomic clocks with quantum computers. "Our goal is to get to the ultimate precision ...

The most expensive item in the world could one day be found in our mobile phones. Scientists at the University of Oxford ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

“Tiqker is a quantum-based atomic frequency reference clock designed to meet national security and commercial demands for precise timing in environments where satellite-based time standards are ...

The simple reason is that it takes much more energy to excite a nucleus into a higher energy state than it does an atom. Atomic clocks typically excite cesium atoms with photons of energy 4 x 10-5 ...

Off-the-shelf quartz watches are accurate to within less than a second a day. A good cesium atomic clock may shift by a second over 100 million years. Since 1967, the “second” has been defined ...
