The watch on your wrist might seem pretty accurate on a day-to-day basis but it’s got nothing when compared to atomic clocks. Scientists use atomic clocks for a variety of purposes, and the more ...

On this week’s “More To The Story,” Daniel Holz from the Bulletin of the Atomic Scientists discusses why the hands of the ...

The data is in for an atomic clock sent to space in 2019 and a JPL scientist explains what the Deep Space Atomic Clock means for the future of GPS and space travel.

Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

The Doomsday Clock was moved forward on Tuesday to 90 seconds to midnight due in part to worries over Russian's veiled threats of nuclear warfare.

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only ...

Atomic clocks use these frequencies — specifically, absorbing and emitting photons at regular intervals to keep time. They are the most accurate clock we have to measure time in seconds.

I was surprised to hear that the Doomsday Clock isn't just a storytelling device Alan Moore made up for Watchmen. The real-life Doomsday Clock is a representation of how close humanity is to ...

The resulting atomic clocks that set official international times today are astonishingly robust, losing only about one second every 100 million years.

A radio-controlled clock has a radio inside, which receives a signal that comes from a place where an atomic clock is located, so they are always accurate, according to the National Institute of ...

The First Nuclear Clock Will Test if Fundamental Constants Change An ultra-precise measurement of a transition in the hearts of thorium atoms gives physicists a tool to probe the forces that bind the ...

London watchmaker Hoptroff has produced the world's first watch with true atomic-clock accuracy. Several manufacturers already offer affordable watches that synchronise to the radio signals ...
