The Elements of Non Euclidean Geometry (1909)

The Elements of Non-Euclidean Geometry is a book written by Julian Lowell Coolidge and published in 1909. The book is a comprehensive introduction to the field of non-Euclidean geometry, which is a branch of geometry that explores the properties of geometric figures and spaces that are not consistent with Euclid's axioms. The book begins with an overview of the history of non-Euclidean geometry, including the work of mathematicians such as Lobachevsky and Bolyai. The author then delves into the basic concepts of non-Euclidean geometry, including hyperbolic and elliptic geometry, and provides a detailed explanation of the differences between these two types of geometry. The book also covers a variety of topics related to non-Euclidean geometry, including the geometry of the sphere, the geometry of the hyperbolic plane, and the geometry of n-dimensional spaces. The author provides numerous examples and illustrations throughout the book to help readers understand the concepts being discussed.Overall, The Elements of Non-Euclidean Geometry is a valuable resource for anyone interested in the field of geometry, including students, teachers, and mathematicians. The book is written in a clear and concise style, making it accessible to readers with a range of mathematical backgrounds.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
