A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
In August 2004, NIST scientists demonstrated a chip-scale atomic clock that was 100 times smaller than an ordinary atomic clock and had a much smaller power consumption of 125 mW. [ 33 ] [ 34 ] The atomic clock was about the size of a grain of rice with a frequency of about 9 GHz.
The clock is meant as a metaphor for how close humanity is to self-annihilation, according to the Bulletin of the Atomic Scientists, which has maintained it since 1947. The group was founded two ...
Its atomic timepieces use chip scale atomic clock technology, [14] where a small vessel of Caesium 133 is exposed to 130 °C. [15] A laser is used to excite the atoms and a microwave resonator which causes the hyperfine transition frequency of the atoms. The resultant watch after this process has a higher accuracy of 1.5 seconds every thousand ...
