Bathys Hawaii, a US-based watch company, has created the Cesium 133, a prototype wrist watch that has its own atomic clock. The fact that the clock is self-contained, integrated into the wristwatch, is the distinguishing ...
(Phys.org) —Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago.

Atomic clocks based on the oscillations of a cesium atom keep amazingly steady time and also define the precise length of a second. But cesium clocks are no longer the most accurate. That title has been transferred to an ...
