Time dilation, a captivating concept embedded in Einstein’s theory of relativity, has been experimentally validated on Earth.

Researchers at Delft University of Technology in the Netherlands have observed the magnetic nucleus of an atom flipping ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time.

On Sept. 2, 1752, the British switched from the Julian calendar to the Gregorian calendar. To make this work, Wednesday, Sept ...

Atomic Clock: A device that utilises the natural oscillations of atoms to maintain time with exceptional accuracy. Frequency Standard: A reference device or signal used to calibrate and measure ...

BRAUNSCHWEIG, Germany — Time measurement is entering a new era. The next generation of atomic clocks uses laser light instead of microwaves to track time, oscillating about 100,000 times faster ...

An atomic clock that could pave the way for autonomous deep space travel was successfully activated last week and is ready to begin its year-long tech demo, the mission team confirmed on Friday ...

Scientists at Delft University of Technology have managed to watch a single atomic nucleus flip its magnetic state in real time. Using a scanning tunneling microscope, they indirectly read the nucleus ...

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.
