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.
Femtosecond
A femtosecond (fs) is a unit of time equal to 10^-15 seconds, or one quadrillionth of a second.
History/Origin
The femtosecond was introduced in the 20th century with advancements in ultrafast laser technology, enabling measurement and manipulation of phenomena occurring on extremely short timescales.
Current Use
Femtoseconds are used in fields such as physics, chemistry, and biology to study ultrafast processes like chemical reactions, electron dynamics, and laser pulse durations.
