LARGE DISPLAY: Easy to read 4″ high display SELF-SETTING/ADJUSTING: Using radio frequencies broadcast from NIST’s Colorado Atomic Clock. (Atomic feature only ...

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 ...

the protons and neutrons in atomic nuclei can also occupy an excited state. This nuclear isomer (metastable) state is a big part of radioactive decay chains, but can also be induced externally.

we too often encounter ones that were installed and set to operate at their maximum water temperature and the outdoor sensor was never installed. The building owners were led to believe they were ...

A new ultra-precise atomic clock outperforms existing microwave clocks in time-keeping and sturdiness under real-world conditions. The clock, made by a team of researchers from the California, ...

Researchers at Vector Atomic have developed a revolutionary new atomic clock that boasts both exceptional precision and remarkable portability. Unlike its bulky lab-bound predecessors, this ...

Each sharp plasma-etched feature seen here is smaller than 10 micrometers—a hundredth of a millimeter—across. Highly accurate ...

This method gives scientists an ultraprecise measurement of the laser's frequency, from which they can extract the "tick" of the atomic clock. However, atomic clocks are far from perfect.

Atomic clocks are usually either ultra-precise or sturdy, but not both. Now, scientists have created a precise clock that, when put through its paces aboard a naval ship, wavered by only 300 ...

Opinions expressed by Forbes Contributors are their own. I write about physics, science, academia, and pop culture. To start with, our current definition of time is based on cesium atomic clocks ...
