An Elementary Treatise On Descriptive Geometry: With A Theory Of Shadows And Of Perspective is a book written by Gaspard Monge and originally published in 1851. The book is a comprehensive guide to the principles of descriptive geometry, which is the branch of mathematics that deals with the representation of three-dimensional objects in two dimensions. Monge's book provides a detailed explanation of the concepts and techniques used in descriptive geometry, including the use of geometric constructions, projections, and sections. The book also includes a theory of shadows and perspective, which explores the way in which light and shadow interact with objects and how they are perceived by the human eye. Throughout the book, Monge uses a clear and concise writing style and includes numerous diagrams and illustrations to help readers understand the concepts presented. The book is designed for students and professionals in the fields of mathematics, engineering, architecture, and art who are interested in learning about the principles of descriptive geometry and how they can be applied in practice. Overall, An Elementary Treatise On Descriptive Geometry: With A Theory Of Shadows And Of Perspective is a valuable resource for anyone seeking to deepen their understanding of this important branch of mathematics and its practical applications.This Is A New Release Of The Original 1851 Edition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
