Could the first people on Mars need their own time system? Here's what a NASA researcher says
Without a standard time system, clocks around Mars would all run on slightly different times.
A trapped cloud of ultracold atoms, colder than almost anything found in nature, has become the setting for a deceptively ...
In recent years, many physicists worldwide have introduced atomic clocks, systems to measure the passing of time that are based on quantum states of atoms. These clocks can have numerous valuable ...
Optical atomic clocks operate by tuning the frequency of a laser (optical local oscillator, OLO) into resonance with a narrowband electronic transition in an atomic system 4,5. By so doing, the ...
