MessageLet's imagine that the Earth is an ideal Sphere of unit Radius. Points A , B and C are some Cities on it: Moscow(A), New York(B) and Tokyo(C) for example. When you travel by the shortest way from Moscow to New York (AB) and then from New York to Tokyo(BC) also by the shortest way, the resulting geodesical arc on the Earth from Moscow to Tokyo (AC)being the shortest way from Moscow to Tokyo(AC)which IS BUT MULTIPLICATION product of Quaternions (AB) & (BC):
(AC)=(AB)@(BC),
with all needed requirements for multiplication @ being satisfied.
Every geodesical arc (AB)on the Unit Sphere correspondes to a Quaternion. If A=B then quaternion (ABB) is equal to 1. If A is diametrally opposite to B, then (AB) is equal to -1.The i j k quaternions being arcs along equator, Grinvich ang 90 degree after Grenvich meridians with longitude 90 degrees. Twisely taken i or j or k quternion gives rise to -1. etc.
