A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is 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 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
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.
