The Russian edition of this book appeared in 1976 on the hundred-and-fiftieth anniversary of the historic day of February 23, 1826, when LobaeevskiI delivered his famous lecture on his discovery of non-Euclidean geometry. The importance of the discovery of non-Euclidean geometry goes far beyond the limits of geometry itself. It is safe to say that it was a turning point in the history of all mathematics.

This is a reissue of Professor Coxeter's classic text on non-Euclidean geometry. It begins with a historical introductory chapter, and then devotes three chapters to surveying real projective geometry, and three to elliptic geometry.

Galilean geometry is the study of the x-t plane under the motions that correspond to changes in time origin and change of uniform motion coordinate system. Although we introduce this geometry on physical grounds, we quickly move on to study this geometry in its own right without any physical motivation.

The look at Non Euclidean Geometry is part of the History of Mathematics and profiles some of the main figures involved including Carl Friedrich Gauss & Wolfgan & Yanosh Bolyai. The programme also examines the different Geometries that they explored. The short about Paul Banchoffs attempts to visualise the unseeable 4th Dimension is intriguing and includes a nice animation of a hypercube (or tesseract).
