Step Closer to an Atomic Clock That is Now Three Times More Precise

A clock that is so precise that it loses only a second every 300 million years - this is the result of new research in ultra cold atoms. The international collaboration is comprised of researchers from the University of Colorado, USA and the Niels Bohr Institute at the University of Copenhagen and the results have just been published in the prestigious scientific journal, Science.
