Gizmag Comment Feed: World's most precise clock keeps time to 1 second in 3.7 billion years http://www.gizmag.com Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that would neither gain nor lose one second in about 3.7 billion years. That makes it the world’s most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom.en gizmag.com Comment on 'World's most precise clock keeps time to 1 second in 3.7 billion years' by Anumakonda Jagadeesh http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-19285 http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-19285 Wed, 07 Apr 2010 02:07:51 -0500 Comment on 'World's most precise clock keeps time to 1 second in 3.7 billion years' by Gruph Norgle http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-14686 http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-14686 Sun, 07 Feb 2010 13:37:07 -0600 Comment on 'World's most precise clock keeps time to 1 second in 3.7 billion years' by Rolf Hawkins http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-14614 http://www.gizmag.com/worlds-most-precise-clock/14088/#comment-14614 Fri, 05 Feb 2010 11:45:48 -0600
