New Strides Toward Better Clocks, Accurate To One Second In 32 Billion Years

12:00AM May 16, 2011 | Rebecca Boyle - Pop Sci

The slightest whisper of warmth induces miscalculations in the world’s most precise atomic clock, researchers say. Accounting for this effect can make future clocks even more precise, eventually leading to atomic clocks that lose only one second every 32 billion years – about two and a half times the age of the universe itself.

Quantum Clock Is 100,000 Times More Accurate Than Atomic Clock

5:15AM February 7, 2010 | Kyle VanHemert

As Make put it, the atomic clock is old and busted. And the quantum-logic clock from National Institute of Standards and Technology, keeping time 100,000 times more accurately than its predecessor, is definitely the new hotness. More »

Atomic Clocks to Go Portable

12:50AM March 17, 2009 | Mark Wilson

Right now, an atomic clock works by sending atoms through a vacuum, microwaving them and measuring how many waves it takes to maximise atom florescence (that’s 9,192,631,770 microwaves or one second).
