# Earth Grids

20 21 In 1978, Professors William Becker and Bethe Hagens extended the Russian model, inspired by Buckminster Fullers geodesic domes, into a grid based on the rhombic triacontahedron shown opposite right, the dual of the icosidodecahedron Archimedean solid see Platonic Archimedean Solids, also in this series. The triacontahedron has 30 diamondshaped faces, and possesses the combined vertices of the icosahedron and the dodehedron. Their new model, which they later titled The Rings of Gaia, revealed 15 great circles, 120 scalene right triangles with no equal sides or equal angles and 62 nodepoints. The great circles divided each rhombic face into four righttriangles. Although having no interest in Earth grids, Fuller had previously noticed these triangles and recorded their internal angles in planar and spherical notations shown below. The model was eventually developed into the Unified Vector Geometry UVG projection, connecting all of the vertices of the five Platonic solids placed inside a sphere, using Fullers great circle sets from Synergetics II. A total of 121 great circles appeared, increasing the number of vertices to 4,862 see opp. page 1. They proposed that the UVG grid could be a new geometrical model for Gaia. puTTinG iT all ToGeTher the unified vector geometry projection cups and rings from Rosshire Above The grid is oriented to the poles and northsouth through Giza.
