Point
A point is a unit of typographical measurement. In the context of printing, it is approximately 1/72 of an inch.
History/Origin
The point system of typography was developed in the 18th century. It provides a standardized way to measure font sizes and leading.
Current Use
The point is the standard unit for measuring font sizes in both print and digital media.
Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
