  2. Atmos clock - Wikipedia

    en.wikipedia.org/wiki/Atmos_clock

    The first clock powered by changes in atmospheric pressure and temperature was invented by Cornelis Drebbel in the early 17th century. Drebbel built as many as 18 of these, the two most notable being for King James VI & I of Britain, and Rudolf II of Bohemia. The King James clock was known as the Eltham Perpetuum, and was famous throughout Europe.

  3. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    The development of atomic clocks has led to many scientific and technological advances such as precise global and regional navigation satellite systems, and applications in the Internet, which depend critically on frequency and time standards. Atomic clocks are installed at sites of time signal radio transmitters. [103]

    List of UTC timing centers is a list of over 70 recognized maintainers of atomic clocks around the world from which UTC is calculated. [1] Below are links to some of the more notable time centers which contribute to the calculation of UTC.

  6. International Atomic Time - Wikipedia

    en.wikipedia.org/wiki/International_Atomic_Time

    International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]

  7. Hafele–Keating experiment - Wikipedia

    en.wikipedia.org/wiki/Hafele–Keating_experiment

    Three atomic clocks were brought to an altitude of 10 km above Chesapeake Bay in Maryland, and three other atomic clocks were at the ground. A turboprop plane was used, flying at only 500 km/h, in order to minimize the velocity effect. The plane was steadily observed using radar, and its position and velocity were measured every second.
