Atomic clock to sync handhelds Its physics package, or atomic works, is about the size of a grain of rice, making it potentially easy to mass produce and integrate with hand-helds and other electronics. It is accurate within 25 microseconds per day, or about a second per 126 years. mark for My Articles similar articles

Light clock promises finer time Researchers have made a prototype atomic clock that divides time on optical radiation, rather than microwave radiation. Such clocks could eventually improve global positioning systems, make space exploration more accurate, and more accurately test the laws of physics. mark for My Articles similar articles

Quantum timepiece ticks the right boxes In a remarkable feat of quantum horology, scientists in the US have created a clock that derives its timing mechanism from nothing more complicated than the mass of an atom. The new clock could prove to be a new way to make highly accurate measurements of atomic mass. mark for My Articles similar articles
