DESCRIPTION:Classical mechanics can be formalized using Euclidean geometry
  (the one we learn at school\, with Pythagorean's theorem\, similar triang
 les\, etc). In such a world light travels along straight lines as these pa
 ths are the one minimizing their travel time. Since the 19th century mathe
 maticians have created and studied new geometrical "worlds" where the axio
 ms of Euclidean geometry no longer hold. These geometries have been a sour
 ce of inspiration for some artists such as M. C. Escher\, who drew remarka
 ble pictures of the hyperbolic space in two dimensions. Using the power of
  modern computers\, one can now simulate what it would be to live an a non
 -Euclidean three-dimensional space. In such a world light rays may bend\, 
 thus changing our large-scale perception of the surrounding space. The tal
 k will be a journey in these non-Euclidean geometries.
