Scientist Working on a Chip-Scale Atomic Clock

Researchers are working on tiny, wristwatch-size atomic clocks that stay as accurate as larger clocks, yet consumes little power and costs less to build. These smaller atomic clocks could back up the atomic clocks in GPS satellites. One day they could be part of every GPS receiver or provide timing for communications of all sorts.
