The best timepieces tend to be fragile, but a device based on iodine threads the needle between precision and practicality.

"State-of-the-art atomic clocks are now so precise they are sensitive to gravity," Bohr said. "There are proposals that if we have atomic clocks that are portable and precise enough, we can place them ...

Even your Macbook or smartphone displays time which is synchronized to the NIST-F1 clock, a cesium fountain atomic clock (aka the ‘Atomic Clock’) that is part of a global consortium of atomic ...

A team of physicists and engineers at Vector Atomic, Inc., a maker of navigation and communications equipment, has developed ...

Atomic clocks, the paragon of precision time measurement, might soon become even more accurate thanks to a quantum process ...

Why Trust Us? 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 ...

Moreover, atomic clocks use radio waves to constantly synchronize various devices, including computers, phones, and ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into ... frequency of the laser’s light. To home in on that frequency, scientists ...

Solid-state ticker: thorium-229 could form the basis of a chip-based nuclear clock. (Courtesy: iStock/Tadamichi) A nuclear clock based on thorium-229 is one step closer now that researchers in Germany ...

though “atomic clock” is to some degree a misonomer. The “tick” of the clock is the oscillation of light waves— one second is by definition 9,192,631,770 oscillations of the microwaves ...
