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.
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.
