Second
The second (symbol: s) is the base unit of time in the International System of Units (SI), used to measure durations and intervals.
History/Origin
The second was originally defined as 1/86400 of a mean solar day. It was later redefined in 1967 based on atomic properties, specifically as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the cesium-133 atom.
Current Use
The second is universally used in science, technology, and everyday life to quantify time intervals, synchronize clocks, and coordinate activities across various fields.
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.
