M. Minchin Uniplanar Kinematics 260 θ is what we have called the expansion, while ω is the spin-vector at P. 1899 C. J. Joly in W. R. Hamilton Elem. Quaternions (ed. 2) I. iii. ii. 492 This vector γ has been called the spin-vector of the function ϕ. 1948 Physical Rev. 73 415/1 The integral Lorentz transformations are represented by exactly those spin transformations which, together with their inverse, map integral spinvectors into integral spinvectors. 1981 Sci. Amer. Apr. 47/3 A particle with one-half quantum of intrinsic spin can have only two possible orientations; in the simplest case, where the particle is in motion, the spin vector can point either in the same direction the particle is moving or in the opposite direction. < as lemmas |
