We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...
Atomic clocks exploit the properties of atoms to create incredibly precise 'ticks.' Nate Phillips, NIST Most clocks, from ...
Chinese breakthrough in ultraviolet crystals could lead to navigation systems resistant to jamming ...
Physicists have suggested the possibility of experimentally confirming the phenomenon of time's flow existing in multiple ...
For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...
Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...
Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using ...
To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.
