Planck Time
Planck time is the theoretical minimum meaningful unit of time, approximately 5.39 × 10^-44 seconds, representing the time it takes for light to travel one Planck length in a vacuum.
History/Origin
Introduced by physicist Max Planck in 1899 as part of his system of natural units, it arises from fundamental constants and marks the scale at which classical ideas about gravity and space-time cease to be valid, requiring a quantum theory of gravity.
Current Use
Primarily used in theoretical physics and cosmology to describe phenomena at the Planck scale, and as a fundamental unit in models of quantum gravity; it is not used in everyday measurements.
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.
