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.
Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
