These are illustrations of the “Spaceship Earth” Epcot building in Florida. This directly reflects complex geometrical properties, for this is a unusually prodigious geodesic dome. The geosphere is 165 feet in diameter, 180 feet high (it stands 15 feet off the ground), encompasses 2,200,000 cubic feet of space, weighs 15.5 million pounds, has an outside surface of 150,000 square feet, and is covered by 11,324-silvered facets on 954 triangular panels. The exterior tiles are made of Alucobond® material, a composite of ethylene …showed first 75 words of 391 total…
