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.
Attosecond
An attosecond is a unit of time equal to 10^-18 seconds, used to measure extremely short durations, particularly in atomic and subatomic processes.
History/Origin
The attosecond was introduced in the early 21st century as scientists developed ultrafast laser techniques to observe electron dynamics, marking a significant advancement in time measurement at atomic scales.
Current Use
Attoseconds are primarily used in physics and chemistry to study ultrafast phenomena such as electron movements, chemical reactions, and quantum dynamics, often through attosecond laser pulses and spectroscopy.
