- 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 ...

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 ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

I have written several times here about circadian rhythms and the downsides of changing the clock ahead and back twice a year—including deadly reasons why Daylight Savings is bad for you, why many ...
