atomic clock

Researchers have developed the most accurate atomic clock ever built, according to a report carried by Phys.org. The advance pushes precision timekeeping to a new record, a field that underpins GPS navigation, telecommunications and tests of fundamental physics. Details of the team, the method used and how much the accuracy improved over previous clocks were not provided in the headline coverage.

The world's most accurate atomic clock has passed a crucial test, confirming the precision and reliability of the timekeeping technology. Atomic clocks underpin GPS, telecommunications and fundamental physics research, so any advance in accuracy is closely watched by scientists. The result is being reported as a milestone in precision measurement, though details of the test and the team behind it are not specified.
