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 ...

Today’s state-of-the-art optical clocks offer accuracy to 18 decimal places, which is roughly equivalent to measuring the ...

Atoms are the world’s most precise timekeepers – so much so that the second is defined as exactly 9 192 631 770 ticks of a caesium-based atomic clock. Commercially-available versions of these ...

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

A group of physicists has announced one of the highest performance atomic clocks ever made. The instrument is said to measure time so precisely that it will only lose one second every 300 billion ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...

Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...
