For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...

Atomic clocks, which are used to measure standard time and calculate GPS, boast extremely high accuracy, with an error of just one second per several hundred thousand ...

– Simultaneous and high availability operation of "a redefinition candidate" and "a current definition" of the second that contribute to international atomic time is key – Currently, the second is ...

The National Metrology Institute of Japan (NMIJ) at National Institute of Advanced Industrial Science and Technology (AIST) has successfully developed an “atomic fountain primary frequency standard ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

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 ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

The project shows a nixie clock that is accurate to a few nanoseconds a day while being synchronized with a cesium atomic clock. The project shows a nixie clock that is accurate to a few nanoseconds a ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

General theory of relativity shows that the flow of time changes when there are heavy objects around. The fact that the farther away from the heavy object of the earth, the faster the time advances, ...
