jaron's world: shapes in other dimensions

al lifelong obsession leads to the mysterious hedecatope—a seemingly impossible geometric form that, in its own small way, links together the whole universe.
by jaron lanier

as a little boy i would look into the bright, immediate stars of the new mexico night and curse the immensity of space. some of those lights must be suns that warm other living beings, i told myself. if i could only meet that other life, i would have something to compare with the singular, lonely shape of life on earth. then i could know a little more of my place in the universe and be a little less alone. like many other children who had pondered the night sky, i became fascinated with the one meeting of minds we already have with the aliens who may be hiding out there, too far away for our telescopes to resolve: mathematics.

consider the platonic solids. these are shapes, like the cube and the tetrahedron (the regular three-sided pyramid) in which every angle, every facet, and every edge is identical. there are only five such shapes in the three-dimensional world; the other three are the octahedron (eight triangular sides), icosahedron (20 triangles), and dodecahedron (12 pentagons). this was proved in ancient times by euclid, and it is hard to overstate how profoundly amazing this proof must have been—and remains. the identities of the five shapes, and the certainty that there can be no more than five, is absolute and universal. while it is possible that an alien would never think to ask the question, all life everywhere would indisputably agree on the answer. a mathematical proof is something anyone can do, yet it is bigger than the universe.
