GEO900/GALLERY
GEO900 is accurately based on Geodesic principles. The term derives from two Greek words; ‘Geo’ meaning earth and ‘Desic’ meaning measurement. Geodesic literally means ‘to measure the earth’. Using trigonometry the ancient Greeks used triangles to measure spheres, and Eratosthenes was able to measure the Earth to within 200 miles of its actual circumference using this method. The 900 comes from it’s weight (900g) and it’s diameter (900mm). The lengths of the struts for GEO900 are not the same. A 3V (three frequency) dome like this uses three different strut lengths to accuratly make up a sphere from triangles (making hexagons and pentagons).
