The distinguished mathematician John Conway presents quadratic forms in a pictorial way that enables the reader to understand them mathematically without proving theorems in the traditional fashion. One learns to sense their properties. In his customary enthusiastic style, Conway uses his theme to c[...]

An investigation of the geometry of quaternion and octonion algebras, this text is intended for mathematicians who are interested in the symmetries of low-dimensional space. Topics covered include Moufang loops, integral octonions and the octonion projective plane.[...]

Over the past two centuries the lives of American Indians have been romanticised and idealised in everything from Hollywood films to souvenir shops. Fritz Scholder took another approach in his artwork. He blended figurative and Pop Art influences to create compelling and revolutionary images that ch[...]
