Barleycorn
A barleycorn is an old English unit of length, equal to one-third of an inch.
History/Origin
The barleycorn was a unit of measurement in medieval England, and was originally based on the length of a grain of barley. It was a fundamental unit from which other units were derived.
Current Use
The barleycorn is an obsolete unit of measurement, but it is still the basis for shoe sizes in English-speaking countries.
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.
