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

Laser made from single atom The simplest possible laser -- a single atom -- has been on the drawing board for decades. Researchers have finally achieved the extremely precise control needed to make a laser from just one atom.
