""A Primer of Quaternions"" is a book written by Arthur Stafford Hathaway and published in 1896. The book is a comprehensive introduction to the mathematical concept of quaternions, which are a type of hypercomplex number system that extends the idea of complex numbers to four dimensions. The book begins with an overview of the history of the development of quaternions, including the contributions of mathematicians such as William Rowan Hamilton. Hathaway then explains the basic properties of quaternions, including their algebraic structure, geometric interpretation, and applications in physics and engineering. Throughout the book, Hathaway provides numerous examples and exercises to help readers understand the concepts presented. He also includes a detailed appendix that covers advanced topics such as the calculus of quaternions and their use in the theory of relativity. Overall, ""A Primer of Quaternions"" is a valuable resource for anyone interested in learning about this fascinating mathematical topic. Its clear explanations and practical examples make it accessible to both students and professionals in fields such as physics, engineering, and computer graphics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
