At first glance, Lucy-Anne's life may not seem any different from any other young girl. But look closer and you will find that Lucy-Anne's world is a magical place where a blanket on the washing-line turns into a hungry elephant, or where you suddenly find yourself turned into a runner-bean.

<p>This book investigates the geometry of quaternion and octonion algebras. Following a comprehensive historical introduction, the book illuminates the special properties of 3- and 4-dimensional Euclidean spaces using quaternions, leading to enumerations of the corresponding finite groups of symmetries. The second half of the book discusses the less familiar octonion algebra, concentrating on its remarkable "triality symmetry" after an appropriate study of Moufang loops. The authors also describe the arithmetics of the quaternions and octonions. The book concludes with a new theory of octonion factorization. Topics covered include the geometry of complex numbers, quaternions and 3-dimensional groups, quaternions and 4-dimensional groups, Hurwitz integral quaternions, composition algebras, Moufang loops, octonions and 8-dimensional geometry, integral octonions, and the octonion projective plane.</p>

<p>For all who relish tales of the Civil War, this work will provide a glimpse into the lives of the women and men who forever will be associated with Savannah through their wartime deeds. Beginning with secession fever in 1860, the author leads us through stories about Robert E. Lee's sojourn in Savannah, the building of the ironclads, the fall of Fort Pulaski and Fort McAllister, Sherman's march to the sea, and the death of the Confederacy in 1865.</p>
