Time clock solutions are essential for small businesses to efficiently track employee hours and manage payroll. These systems ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

Different clocks measure the frequencies of different types of atoms, each with its own unique frequency. This means the only way to establish a consistent, highly precise standard is to directly ...

The newly developed clock will drastically shorten this measuring time by parallelizing: multiple ions—often of different kinds—will be simultaneously trapped in one trap.

NASA’s 2019 Deep Space Atomic Clock mission demonstrated the best atomic clock in space to date, Safronova said, but different types of clocks — based on much higher frequencies — have been developed ...

A powerful laser generates ultraviolet light as it shines into a jet of gas. For a nuclear clock to work in a new study, scientists used UV light to excite nuclear particles in an atom of thorium-229.

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...
