  Kepler Believed the universe was ruled by the relationship between 5 perfect bodies. Are you ready to begin your cosmic domination?  This set is arguably the Rosetta stone of Zometool. It demonstrates how the cubic worlds intersect with icosahedral symmetry. And it's all thanks to John Conway and his discovery of the most tightly packed nesting of the five platonic solids -- using the Zometool! While searching for a system behind the relationships of the distances between the planets and the sun, the German mathematician and astronomer Johannes Kepler (1571-1630) hoped to discover a "construction plan of the world". Kepler spent his life searching for the music of the spheres, HOPING to prove that God determined the orbits of the planets by nesting the five "perfect" Platonic solids. But when he analyzed the data, he proved himself wrong. And being a good scientist, Johannes Kepler admitted it... and founded modern astrogeophysics!        Specs:   Struts 120 Nodes 38 Total Parts 158   Parts Chart   Name 0 Short 1 Medium 2 Long B Blue 30     Y Yellow       R Red 12     G Green         Nodes Color Qty 38   Nonstandard Parts   Name Length Description Qty B Blue 1 B1 in Red 30 B Blue 2 B2 in Yellow 12 HG Half-Green 0 HG0 in Teal 12 HG Half-Green 1 HG1 in Teal 12 HG Half-Green 2 HG2 in Green 12 Instructions Download Recommended ages 6+ Parts included 158 Dimensions 5.25" x 5.25" x 5.25" Weight 0.8 lbs UPC 709743200226 SKU 0B-KPK-KIT
