New Atomic Clock Could Redefine the Second

bmahersciwriter writes "The new type of clock, called an optical lattice clock could replace the cesium fountain clocks used as the standard for time keeping. Indeed, it could redefine the second. The cesium fountain is predicted to keep time within one second over 100 million years. While other atomic clocks are better than that, researchers suspect the optical lattice is better still and could one day replace the standard."
