Second (Sidereal)
A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.
History/Origin
The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.
Current Use
The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
Millisecond
A millisecond (ms) is a unit of time equal to one thousandth of a second.
History/Origin
The millisecond was introduced as a standard unit of time measurement with the development of precise timekeeping and scientific instrumentation in the 20th century, particularly with the advent of electronic clocks and digital technology.
Current Use
Milliseconds are widely used in computing, telecommunications, and scientific measurements to denote very short durations, such as in data processing, network latency, and high-frequency trading.
