Hour
An hour is a unit of time equal to 60 minutes or 3,600 seconds.
History/Origin
The hour has origins in ancient civilizations, notably the Babylonians, who divided the day into 24 hours. The modern 24-hour system was standardized in the 14th century and became widely adopted with the advent of mechanical clocks.
Current Use
Hours are used globally to measure and schedule time in daily life, work, transportation, and various scientific and technical applications.
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.
