Petameter
A petameter is a unit of length in the metric system equal to 10^15 meters.
History/Origin
The prefix "peta-" for 10^15 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The petameter is used for measuring distances on a galactic scale, such as the size of the Milky Way galaxy.
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.
