Year (Sidereal)
A sidereal year is the time it takes for the Earth to complete one orbit around the Sun relative to the fixed stars, approximately 365.25636 days.
History/Origin
The concept of the sidereal year has been used since ancient astronomy to measure Earth's orbital period relative to distant stars, predating the Gregorian calendar system.
Current Use
Sidereal years are used in astronomy to track Earth's position in its orbit relative to fixed stars, aiding in celestial coordinate calculations and star cataloging.
Femtosecond
A femtosecond (fs) is a unit of time equal to 10^-15 seconds, or one quadrillionth of a second.
History/Origin
The femtosecond was introduced in the 20th century with advancements in ultrafast laser technology, enabling measurement and manipulation of phenomena occurring on extremely short timescales.
Current Use
Femtoseconds are used in fields such as physics, chemistry, and biology to study ultrafast processes like chemical reactions, electron dynamics, and laser pulse durations.
