F4, the latest cesium fountain clock that now stands as one of the most accurate timekeepers in the entire world.

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.

NIST-F4 measures an unchanging frequency in the heart of cesium atoms, the internationally agreed-upon basis for defining the second since 1967. The clock is based on a "fountain" design that ...
