Fathom
A fathom is a unit of length equal to 6 feet, used especially for measuring the depth of water.
History/Origin
The term "fathom" comes from the Old English word "fæthm," meaning "outstretched arms," as the distance was originally the span of a man's outstretched arms.
Current Use
The fathom is still used in nautical applications, especially in the United States, to measure water depth. It is also used in commercial fishing to measure the length of lines.
Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
