Long Cubit
A long cubit is an ancient unit of length, slightly longer than the common cubit. Its length varied but was often around 20.6 inches.
History/Origin
The long cubit, or royal cubit, was used in ancient Egypt for monumental construction.
Current Use
The long cubit is an obsolete unit of measurement.
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.
