Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
