Hand
A hand is a unit of length equal to 4 inches.
History/Origin
The hand was originally the width of a man's hand, including the thumb. It was standardized to 4 inches for measuring the height of horses.
Current Use
The hand is still used today to measure the height of horses.
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.
