Point
A point is a unit of typographical measurement. In the context of printing, it is approximately 1/72 of an inch.
History/Origin
The point system of typography was developed in the 18th century. It provides a standardized way to measure font sizes and leading.
Current Use
The point is the standard unit for measuring font sizes in both print and digital media.
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.
