# scalar
## English
### Etymology

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

scalar (not comparable)
* (mathematics) Having magnitude but not direction.
* (computer science) Consisting of a single value (e.g. integer or string) rather than multiple values (e.g. array).
* Of, or relating to scale.
** 2003, Rodney O. Fox, Computational Models for Turbulent Reacting Flows: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.
** 2015, Raymond L Bryant, The International Handbook of Political Ecology, page 504:Scalar thickening is useful for understanding the propensity of scales to coalesce in certain times and places, or even how a particular scale provides conditions for other forms of scalar production.
* (music) Of or pertaining to a musical scale.
* (physics) Relating to particles with a spin (quantum angular momentum) of 0 (known as spin 0).
* (linguistics) Pertaining to the dimension on which something is measured.
** 2014, Salvatore Pistoia Reda, Pragmatics, Semantics and the Case of Scalar Implicatures:Spector (2006, 2007) suggests to derive this inference as a scalar implicature.
** 2018, Osamu Sawada, Pragmatic Aspects of Scalar Modifiers, page 26:Also, the scalar meaning in both sentences is not sensitive to context, because the truth value of the sentences does not change depending on context.
** 2019, Penka Stateva, Anne Reboul, Scalar Implicatures, page 8:In Mandarin Chinese, the same sentence containing a numeral-classifier phrase as a negative polarity item can be employed for two types of scalar inferences based on either the numeral or the noun.
