It is interesting to note that some 35 years before the Brain Port was invented, a science fiction writer, Don J. Fretland, dreamed up the very same device and wrote about it in his novel, The Persimmon Sequence. It would be safe to assume that Isaiah was not less wise nor less prescient than Mr. Fretland.

Kuipers introduces quaternions for scientists and engineers who have not encountered them before and shows how they can be used in a variety of practical situations. The book is primarily an exposition of the quaternion, a 4-tuple, and its primary application in a rotation operator. But Kuipers also presents the more conventional and familiar 3 x 3 (9-element) matrix rotation operator. These parallel presentations allow the reader to judge which approaches are preferable for specific applications. The volume is divided into three main parts.
