Second
The second is a unit of time representing the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.
History/Origin
The second was originally defined in 1956 based on Earth's rotation but was later redefined in 1967 based on the vibrations of the cesium-133 atom, making it a precise atomic time standard.
Current Use
The second is used universally in science, technology, and daily life to measure time intervals, coordinate universal time (UTC), and in various applications requiring precise timekeeping.
Revolution
A revolution is a complete turn or rotation around a central point, typically measuring 360 degrees in angular terms.
History/Origin
The concept of a revolution as a full rotation has origins in ancient geometry and astronomy, with the term 'revolution' historically used to describe celestial orbits and rotations in various cultures.
Current Use
In modern contexts, the unit 'revolution' (symbol: r) is used to quantify angular displacement, especially in mechanical and engineering applications, where one revolution equals 360 degrees or 2Ο radians.
