Year (Julian)
A year (Julian) is the period of time approximately 365.25 days, based on the Julian calendar, used to measure the length of a complete cycle of seasons and calendar years.
History/Origin
The Julian year was introduced by Julius Caesar in 45 BC as part of the Julian calendar reform, replacing the Roman calendar. It standardized the year length to 365 days with a leap year every four years to account for the extra quarter day.
Current Use
The Julian year is primarily used in astronomical calculations and historical contexts. It is also the basis for the Julian date system used in astronomy and other sciences to record continuous days.
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.
