Geodesic Dome. The concept of the geodesic dome originated with Buckminster Fuller. He patented his design in 1954. A geodesic dome is a spherical or partial-spherical shell structure based on a network of great circles (geodesics) lying on the surface of a sphere.

A geodesic dome is a spherical or partial-spherical shell structure based on a network of great circles (geodesics) lying on the surface of a sphere.
Buckminster Fuller was the scientist who developed the intrinsic mathematics of the dome, thereby allowing popularization of the idea — for which he received a U.S. patent.
A triangle is the only polygon (many-sided) that holds its shape with force acted upon it.
Geodesic domes are an extremely efficient form of architecture
Its decreased surface area requires less building materials.
Exposure to cold in the winter and heat in the summer is decreased because, being spherical, there is the least surface area per unity of volume per structure.
The concave interior creates a natural airflow that allows the hot or cool air to flow evenly throughout the dome with the help of return air ducts.
Extreme wind turbulence is lessened because the winds that contribute to heat loss flow smoothly around the dome.
It acts like a type of giant down-pointing headlight reflector and reflects and concentrates interior heat. This helps prevent radiant heat loss.
The icosahedron's potential for creating new dome designs is infinite. It is a geometric shape made of triangles and is most frequently used to design geodesic domes. It is a 20-sided polyhedron.
Eaves and soffits are great for shedding water, but the wind grabs them and won't let go. Domes don't have any overhangs ~ one reason domes are nearly impervious to strong winds
35 "long" and 30 "short”
Cut off both ends to get correct length
Long = 71 cm
Short = 66 cm
Tape 10 longs together to make the base of the dome
7. Tape a long and a short to each joint. Arrange them so that there are two longs next to each other, followed by two shorts, and so on.
Chord - straight line segment joining two points on a curve
"chord" of the "geodesic sphere" corresponds
to the structural "strut" of the physical "geodesic dome"
triangulation of a Platonic Solid
Fuller hoped that the geodesic dome would help address the post World War II housing crisis.
*Did not catch on because of complexity and consequent greater construction costs.
The frequency of a dome relates to the number of smaller triangles into which it is subdivided.
A high frequency dome has more triangular components and is more smoothly curved and sphere-like
