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.
Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
