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.
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.
