Caesium atomic-fountain clocks are used to set national time standards at NIST, at the Paris Observatory and elsewhere. The caesium fountain clock has an accuracy of about three parts in 10 ...

An atomic clock that keeps time with the help of iodine molecules is sturdy enough to withstand a sea voyage. Credit: Will Lunden. Atomic clocks are usually either ultra-precise or sturdy, but not ...

New clock just dropped, but it’ll only drop a second every 30 billion years while in operation. That’s right: It’s the most precise, accurate clock yet built.

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

In humankind's ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by ...

Researchers have built an atomic clock that is more precise and accurate than any previous clock. For the first time, the clock can detect the effects of gravity predicted by the theory of general ...

World’s First Ultra-Precise Nuclear Clock Is Within Reach After Major Breakthrough, Researchers Say The technology, enabled by thorium atoms, could keep time more accurately than atomic clocks ...

Chinese scientists have built an ultra-precise clock that they hope will redefine the second Credit: Science Photo Library. This brings humans closer to redefining the second as a basic unit of time.

An incredibly precise timekeeping device that experts say could revolutionise British intelligence is being developed at a top secret lab in the UK. The Quantum Clock is expected to be rolled out ...

A laser clock developed by DLR has achieved a record level of accuracy for optical clocks, with a deviation of just one second every 30 million years. Laser clocks are set to improve satellite ...
