Worlds most accurate atomic clock developed
Washington: Physicists have developed a new atomic clock that surpasses previous records for accuracy of current US time standard, making it the world's most accurate atomic clock. Developed by physicists at JILA, a joint institute of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder, the new clock is based on thousands of strontium atoms trapped in grids of laser light.
