We are in the midst of a Renaissance in mathematics education. Descartes' dream is unfolding in the form of dynamic visualization software such as Geometer's Sketchpad, Fathom and Cabri3D. An illumination is quietly spreading across the globe as students all over are starting to enjoy, explore, discover and co-create mathematics as has never happened before in history. Our very notion of mathematical understanding is changing radically. Soon the time will be right for a new generation to walk new landscapes of mathematical thought armed with clearer vision of the marvelous task at hand and a clearer sense of their endless capabilities. How lucky are we to be born to such an era where visions of antiquity are finally ripening!
