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).

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.
