By Eric Smalley - Atomic clocks keep extremely accurate time by measuring the vibration of atoms. They have been around for 50-odd years, but they aren't in widespread commercial use because they tend to be large and draw a lot of power.
Researchers from the National Institute of Standards and Technology (NIST) have devised the principal component of an extremely tiny atomic clock that will draw very little power.
The physics package, or atomic works, of the clock is 9.5 cubic millimeters, or about the size of a grain of rice, and keeps time accurately enough that...
