ˈpseudovector, n. and a. Math. and Physics.
[f. pseudo- + vector.]
A. n. A vector whose sign is unchanged when the signs of all its components are changed.
1923A. S. Eddington Math. Theory of Relativity vi. 179 Rµ is the pseudo-vector representing the displacement from the charge (ξ, η, ζ, τ) to the point (x, y, z, t) where xµ is reckoned... We call it a pseudo-vector because it behaves as a vector for Galilean coordinates and Lorentz transformations. 1938[see pseudoscalar n.]. 1966McGraw-Hill Encycl. Sci. & Technol. II. 413/1 In general, vectors associated with rotations belong to the category of pseudovectors. In particular, the angular velocity vector associated with the motion of a rigid body is a pseudovector. 1972Jrnl. Physics B. V. 992 It is convenient to express in the standard way the (real) antisymmetric tensor A{pp}(t) in terms of the pseudovector V(t) which it uniquely defines.
B. adj. Involving or being a pseudovector.
1947Rev. Mod. Physics XIX. 2/2 We are left with mesons of spin 0..or possibly spin 1 (vector or pseudovector fields). Ibid. 3/1 Little attention has been shown to the pseudovector theory. 1964Cambr. Rev. 24 Oct. 51/1 The assumed conservation of the pseudovector current. |
