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 use of the term “scalar” in mathematics was introduced by William Rowan Hamilton when he introduced the quaternion product.
