BOULDER — A 2007 National Medal of Science has been awarded to David J. Wineland, a physicist at the Boulder campus of the National Institute of Standards and Technology.
Wineland developed a technique of using lasers to cool ions to near absolute zero, the coldest possible temperature, NIST said in a news release.
Wineland’s work led to the development of laser-cooled atomic clocks, the current state of the art in time-and-frequency standards.
