The elements of geometry are points, lines and planes, together with Space and Nothing. In Euclidian geometry, we observe these as if we are point-centered beings concerned with extensive measurement.
In non-Euclidian (projective) geometry, we are “planar” beings observing spatial relationships, free of measurement, as dynamic and transformational. This polar opposite vision of intensive space reveals remarkable secrets.
In this fascinating and useful book, expert Lawrence Edwards invites the reader to discover these secrets through practical exercises in creative geometry.
Topics include: the elements of geometry, duality, collineation, cross ratio, the circling and step measure, conics, and the nature of a curve.
