Domain time and calendars
  • ülitäpne kell, mis kasutab aja mõõtmiseks kvantsüsteemides toimuvaid püsiva sagedusega elektromagnetvõnkumisi
  • clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element
    Good to know
    • Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS.
