On Eccentric And Centric Force: A New Theory Of Projection (1862)

By Henry Pratt

Book Overview

On Eccentric and Centric Force: A New Theory of Projection is a book written by Henry F. A. Pratt in 1862. The book is a theoretical treatise on the principles of projection, which is the process of creating a two-dimensional image of a three-dimensional object. Pratt's theory proposes that there are two types of force at work in the projection process: eccentric force and centric force. Eccentric force is the force that acts upon the object being projected, while centric force is the force that acts upon the projection surface. Pratt argues that these two forces must be balanced in order to achieve an accurate and precise projection. The book includes detailed mathematical formulas and diagrams to support Pratt's theory. Overall, On Eccentric and Centric Force is an important work in the history of projection theory and a valuable resource for anyone interested in the principles of perspective drawing.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
