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.

Nautical Mile (UK)

The nautical mile (UK) is a unit of distance used primarily in maritime and aviation navigation in the United Kingdom. Traditionally, it was defined as 6,080 feet (about 1,853 meters), which is slightly longer than the modern international nautical mile of 1,852 meters. This UK definition was used before international standardization in 1929. Today, the international nautical mile is widely adopted, but the UK nautical mile historically played an important role in navigation and mapping.
