In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology researchers, the latest modification of a record-setting strontium atomic clock has ...

Unfortunately, strontium atoms, of all things, react relatively strongly to changes in the ambient temperature; their atomic levels are then shifted energetically, which causes the clock to become ...

It’s the creation of Alexander Aeppli, a graduate student researcher at the University of Colorado Boulder. For years, Aeppli has been tweaking to perfection an atomic clock that relies on ...

Strontium atomic clocks have important applications, ranging from tests of general relativity to searches for possible variations in fundamental constants. But the precision of these clocks has been ...

An atomic clock that sets the time by the teensy oscillations of strontium atoms has gotten so precise and stable that it will neither gain nor lose a second for the next 15 billion years.
