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.
Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
