The world’s network of atomic clocks is already mind-bogglingly accurate. They also underpin a slew of modern necessities, from GPS to internet communication. Atomic clocks work by tuning a laser to ...

What you'll discover in this article ・The first thorium-229 nuclear clock has been achieved. ・It is not as precise as regular atomic clocks, but it could be a revolutionary tool in probing fundamental ...

Physicists have used radioactive lutetium to create what they say is the most accurate atomic clock ever, keeping time perfectly up to 19 decimal places.

(Patcharin Saenlakon/iStockphoto/Getty Images) The time-keeping offered by your watch or phone may be good enough for day-to-day life, but scientists are much more ambitious in terms of precision, and ...

Scientists in Vienna have achieved a major breakthrough in timekeeping by creating the world’s first self-stabilizing nuclear clock, a technology that could eventually surpass even the most precise ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...

For a clock that keeps time with laser light, even a slight shift in the laser’s frequency changes its rhythm. Researchers in ...

By measuring the squishing and unsquishing of thorium-229 nuclei, two teams created a new type of clock that could someday beat the precision of atomic clocks.

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

Time, like money, only seems important when it’s running out. But to physicists, time is always a big deal. Relativity tells us that the flow of time depends on the circumstances you’re measuring it ...

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...
