- Although many pseudo-symmetric twins are transformable into the simpler form, yet, in some cases, a true polymorph results, the change being indicated, as before, by alterations in
**scalar**(as well as vector) properties. - If we put qo= Sq' - Vq', then qo is called the conjugate of q', and the
**scalar**q'qo = qoq' is called the norm of q' and written Nq'. - This has a reciprocal Q -1= p-r = qq-1 - wp1 rq1, and a conjugate KQ (such that K[QQ'] = KQ'KQ, K[KQ] = Q) given by KQ = Kq-}-rlKp+wKr; the product QQ' of Q and Q' is app'+nqq'+w(pr'+rq'); the quasi-vector RI - K) Q is Combebiac's linear element and may be regarded as a point on a line; the quasi-
**scalar**(in a different sense from the rest of this article) 2(1+K)Q is Combebiac's**scalar**(Sp+Sq)+Combebiac's plane. - The fundamental character of energy in material systems here comes into view; if there were any other independent
**scalar**entity, besides mass and energy, that pervaded them with relations of equivalence, we should expect the existence of yet another set of qualities analogous to those connected with temperature. - The plane is of vector magnitude ZVq, its equation is ZSpq=Sr, and its expression is the bi-quaternion nVq+wSr; the point is of
**scalar**magnitude 4Sq, and its position vector is [3, where 1Vf3q=Vr (or what is the same, fi = [Vr+q.
