Geodesic Dome -- from Wolfram MathWorld
A geodesic dome is a triangulation of a Platonic solid or other polyhedron to produce a close approximation to a sphere (or hemisphere ). The th order geodesation operation replaces each polygon of the polyhedron by the projection onto the circumsphere of the order- regular tessellation of that polygon. The above figure shows base solids (top row) and geodesations of orders 1 to 3 (from top to bottom) of the cube , dodecahedron , icosahedron , octahedron , and tetrahedron (from left to right), computed using Geodesate [ poly , n ] in the Mathematica package PolyhedronOperations` . The first geodesic dome was built in Jena, Germany in 1922 on top of the Zeiss optics company as a projection surface for their planetarium projector. R.
Geodesic Dome
In 1922 Dr. Walther Bauersfeld developed a geodesic dome for Carl Zeiss in Jena Germany, he may be considered as the "inventor" of the geodesic dome.
A geodesic dome is a spherical or partial-spherical shell structure or lattice shell based on a network of great circles ( geodesics ) on the surface of a sphere . The geodesics intersect to form triangular elements that have local triangular rigidity and also distribute the stress across the structure. When completed to form a complete sphere, it is a geodesic sphere .

Mathematical Circles are for students of high school age or younger who want to increase their abilities to reason about mathematical problems. Students who study in circles learn to do mathematical olympiad-style problems (essay or proofs, not quick answer). For more lesson plans and for information on Teachers' Circles which are like math circles but aimed at teachers, go to the Math Teachers' Circle Network . I have been volunteering time at three local circles (in Berkeley, San Jose, and Palo Alto, California) for the past nine years, and have prepared handouts for some of those sessions.

Passive solar energy: Rotate your house away from the sun in summer to cool down and towards the sun in winter to warm up (on demand or automated rotation system). Its aerodynamic form has proven resists without any damage to a wind up to 240km/hour (Taiwan Domespace resisted Cyclone Tim in 1994 and some others without deterioration) . Anti-seismic The seismic ray that would make a 10 story building collapse turns around the ring gear of fixation without finding any perpendicularity.

Ekološko hišo je oblikoval priznani španski oblikovalec Luis de Garrido, ki je ustvaril ekskluzivno domovanje s petindvajsetimi sobami. Zgradba stoji na turškem otoku Sedir, ki je znan tudi kot Kleopatrin otok. Zaradi neobičajnega dizajna objekta in zemljišča, ki je povsem v skladu z imenom, pa je iz zraka videti kot oko egipčanskega boga Horusa.
