Sextant
A sextant is a unit of angular measurement used primarily in navigation and astronomy, equal to 60 arcminutes or one degree.
History/Origin
The sextant was developed in the 18th century as a navigational instrument to measure the angle between celestial objects and the horizon, greatly improving maritime navigation accuracy.
Current Use
Today, the sextant is mainly used for educational purposes, historical demonstrations, and by navigators as a backup tool in celestial navigation.
Radian
A radian is the standard unit of angular measure in mathematics, defined as the angle subtended at the center of a circle by an arc equal in length to the circle's radius.
History/Origin
The radian was introduced in the 19th century as a natural unit of angular measurement based on the properties of circles, providing a more mathematically convenient measure than degrees.
Current Use
Radians are widely used in mathematics, physics, and engineering for calculations involving angles, trigonometry, and periodic functions, serving as the standard angular unit in many scientific contexts.
