Euclid's window : the story of geometry from parallel lines to hyperspace

This text leads us on a journey through five revolutions in geometry, from the Greek concept of parallel lines, to contemporary notions of hyperspace.The narrative takes the form of biographical stories, each about the key figures in the development of geometry, from Euclid who laid the logical foundations, to Albert Einstein, who united space and time in a single non-Eudlidean geometry.It offers an alternative history of mathematics, revealing how simple questions anyone might ask about space - in the living room or in some other galaxy - have been the hidden engines of the highest achievements in science and technology.
