Call it a clock’s clock. Researchers say they have developed the world’s most precise and accurate clock – besting the World’s current timekeeping record holder — the National Institute of Standards ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This unit is all that remains of a ...

Plans for a global network of atomic clocks that are synchronized using quantum entanglement have been unveiled by physicists in the US. The resulting universal time standard would be more accurate ...

An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a "fountain" of cesium atoms, according to a paper by ...

- NICT is the first in the world to generate national standard time by reference to an optical clock. - By adding an optical lattice clock to the time system, time is kept within five billionth of a ...

More than a century of scientific research has established the Big Bang model, often referred to as the standard model of cosmology, as the evolutionary theory of the observable universe. It describes ...

(NEXSTAR) — We’re just a couple of weeks away from the end of daylight saving time, the back half of a twice-a-year practice the U.S. has observed for decades. Whether the U.S. should observe ...
