Nautical Mile (International)
A nautical mile (international) is a unit of measurement used primarily in maritime and aviation contexts. It is defined as 1,852 meters or 1.852 kilometers, which is approximately 1.1508 statute miles. The nautical mile is based on the Earth's geometry, representing one minute of latitude along any meridian. This makes it particularly useful for navigation, as distances on charts and GPS systems often relate directly to degrees of latitude and longitude. The international nautical mile was officially adopted by the United States in 1954 and is now used worldwide for consistency in global navigation. It is closely linked with the knot, a unit of speed equal to one nautical mile per hour. The standardization of the nautical mile has greatly simplified communication and coordination in international travel, trade, and defense across oceans and airspace. Its use continues to be essential in global navigation systems today.
Classical Electron Radius
The classical electron radius is a theoretical length scale associated with the electron, derived from classical electromagnetism. It represents the size of a hypothetical sphere where the electron’s electrostatic energy equals its rest mass energy.
Its value is approximately 2.818 × 10⁻¹⁵ meters (about 2.8 femtometers).
Calculated using fundamental constants: the electron charge, mass, and the speed of light.
It is not the actual physical size of the electron (which is considered point-like in quantum mechanics), but a useful scale in classical physics.
Used in scattering theory and classical electron models.
Key facts:
Classical electron radius ≈ 2.818 × 10⁻¹⁵ m
Represents an electromagnetic length scale, not a physical size
Important in classical models of electron behavior
This radius helps bridge classical and quantum views of particle physics.
