Where it comes from
Borrowed from Latin scālāris, adjectival form from scāla (“a flight of steps, stairs, staircase, ladder, scale”), for *scadla, from scandere (“to climb”); compare scale. The mathematics sense was coined by Irish mathematician and astronomer William Rowan Hamilton in 1846.
adjective
- Having magnitude but not direction.
- Consisting of a single value (e.g. integer or string) rather than multiple values (e.g. array).
- Of, or relating to scale. However, it can be expected that 'scale-similarity' models of this form will be inadequate for describing non-equilibrium scalar fields resulting, for example, from non-equilibrium inlet flow conditions.
- Of or pertaining to a musical scale.
- Relating to particles with a spin (quantum angular momentum) of 0 (known as spin 0).
- Pertaining to the dimension on which something is measured. Spector (2006, 2007) suggests to derive this inference as a scalar implicature.
noun scalars
- A quantity that has magnitude but not direction.
- An amplifier whose output is a constant multiple of its input.
