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.
Year (Leap)
A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.
History/Origin
The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.
Current Use
Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.
