A geodesic dome is an almost spherical structure based on a network of great circles (geodesics) lying approximately on the surface of a sphere. The geodesics intersect to form triangular elements that have local triangular rigidity and yet also distribute the stress across the entire structure. It is the only manmade structure that becomes proportionally stronger as it increases in size. When completed to form a full sphere, it is known as a geodesic sphere. Of all known structures made from linear elements, a geodesic dome has the highest ratio of enclosed volume to weight. Geodesic domes are far stronger as complete units than the individual struts would suggest. It is common for a new dome to reach a critical mass during construction, shift slightly, and lift any attached scaffolding from the ground. It is the strongest unsupported structure in the world.
