FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a ...

Physicists are one step closer to developing a clock based on energy shifts in atomic nuclei.

Currently, most terrestrial atomic clocks are the size of a refrigerator. Enter the Deep Space Atomic Clock, which NASA engineers have been tinkering with for almost 20 years.

Scientists have a set a new record in accurate timekeeping, creating an atomic clock that won’t lose or gain a second in 15 billion years — a time span greater than the estimated age of the ...

A Cold War icon, the clock conveys scientists’ views on humankind’s risk of destroying itself. Its current setting: just 100 seconds to midnight.

Atomic clocks work by using a laser to bounce the electrons in an atom at a given frequency, while nuclear clocks would theoretically do the same for atomic nuclei, and we are a step closer to ...

Exciting development It’s about time. The most precise atomic clock ever made has been created by arranging strontium atoms in a grid-like pattern and then stacking those grids like pancakes ...

Clearly that’s not good enough for a clock at CERN, the European Laboratory for Nuclear Research, where [Daniel] works as an RF engineer.
