Expo 67, United States Pavilion, general view
Such a dome is a modification of steel frame construction using the principle of the triangular truss to form tetrahedrons (solids with four triangular faces). It was invented by Buckminster Fuller (1895-1983,US), who insisted that it was stronger than cubes or squares. The frame is usually of aluminum or other light materials, covered with a skin of plastic or plexiglass. The frame distributes the stress equally among all its parts. Fuller drew the design of the geodesic dome from late 19th century discoveries that tetrahedrons are the basic structure of organic material.
