Synopsis:
  • General class of geometries, that comprises the classical Euclidean geometry as a special case
  • the geometry of the surface of a sphere in which all straight lines are great circles (no parallel lines at all, unless space is flat)
  • Spaces with any number of dimensions
  • Space can be curved instead of flat
  • The curvature of space is measured by a "curvature tensor"
