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.
