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.
Long Reed
The long reed is a unit of length mentioned in ancient texts, such as the Bible, and is thought to be about 10.5 feet.
History/Origin
The exact length of the long reed is uncertain and is subject to historical and scholarly debate.
Current Use
The long reed is an obsolete unit of measurement.
