Judah Levine received the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society Rabi Award on July 24 during a joint symposium on time and frequency held in Prague, Czech Republic. Participants included the IEEE-International Frequency Control Symposium (IFCS), the IEEE-International Ultrasonics Symposium (IUS), the IEEE-International Symposium on the Applications of Ferroelectric (...

In a rural northern Colorado landscape punctuated by plentiful corn fields, a tree farm, an abandoned feedlot, and a handful of McMansions, only one thing is certain: the exact time. The nation’s backup time scale, consisting of four atomic clocks, two measurement systems, and supporting hardware is tucked away inside radio station WWV's remote transmission station, located 12...

When Albert Einstein said, "the only reason for time is so that everything doesn't happen at once," he didn't know about studies performed by Senior Research Associate Christine Hackman and Fellow Judah Levine. These time-and-frequency experts work quite hard to devise ways of comparing the accuracy and stability of the world's premier atomic clocks - so that things like satellite...

JILA plays an important role in the nation’s timekeeping by coordinating precision time transfer of atomic-clock time as determined by the NIST Time Scale. Located in Boulder, Colorado, the Time Scale uses nine atomic clocks and a complex measurement system to determine the exact time. It is calibrated by a cesium fountain atomic clock, which neither gains nor loses one second in 80 million...
