Scientists in Germany have unveiled that the world’s most precise mobile atomic clock is so accurate that it will be off by ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

Most of the atomic clocks in the world - fewer than 500 in total - are housed at standards institutes and used to keep time ...

MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks. The periodic table, first ...
