A huge breakthrough decades in the making was made just a few months ago, and already scientists are realizing its potential: A measurement of the gap between the quantum energy states of a thorium ...

Now, physicists at the US National Institute of Standards and Technology (NIST) and the University of Delaware have developed the most accurate and precise atomic clock yet, using a 'web' of light to ...

Strontium atomic clocks have important applications, ranging from tests of general relativity to searches for possible variations in fundamental constants. But the precision of these clocks has been ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Atomic clocks have served as the world’s most precise means of ...

NIST/JILA Fellow Jun Ye works on JILA's strontium clock. Ye has been instrumental in making the clock 50 percent more accurate than it was a year ago. Physicists have measured and controlled seemingly ...

An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which ...

(Phys.org) —A small team of physicists from the U.S. and Denmark has published a paper in the journal Nature Physics outlining the idea of a collection of atomic clocks located around the world—all ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
