coupled an atomic nucleus to an atomic clock to compare differences in their timekeeping frequencies.… The breakthrough promises to ease the development of the next generation of ultra-precise ...

The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say.

The theory was developed by Neils Bohr's great-grandson. The use of a special type of atom could make even the most advanced atomic clocks more precise, scientists believe. If confirmed ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

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 ...

It is effectively an atomic trap, which keeps tens of thousands of atoms in place and measures time through the reliable movement of electrons around the atom. The clock is described in a not-yet ...

The simple reason is that it takes much more energy to excite a nucleus into a higher energy state than it does an atom. Atomic clocks typically excite cesium atoms with photons of energy 4 x 10-5 ...

Scientists from the University of Colorado Boulder have created an atomic clock using lasers and strontium atoms that’s incredibly accurate—only losing one second every 40 billion years.

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.
