Geodesic domes use triangular elements because triangles are the only truly rigid polygon

The term “geodesic” was coined by Walther Bauersfeld

A 3‑frequency (3v) dome has each original triangle subdivided into nine smaller triangles

Buckminster Fuller received his US patent for the geodesic dome in 1954

An icosahedron has 12 faces

Higher‑frequency domes approximate a sphere more closely than lower‑frequency ones

The “Biosphere” in Montreal was built for Expo 67

Struts in a geodesic dome must all be different lengths

Hubs are connectors that join struts at nodes and must accommodate varied angles.

PVC is never used for geodesic dome struts because it cannot bear any load.

The space‑frame principle means loads are transferred in two dimensions only

A geodesic dome’s aerodynamic shape reduces wind resistance

Complex hub fabrication is a common disadvantage of geodesic domes

Fenestration (windows/doors) installation is simpler in a geodesic dome than in a rectangular building

The Eden Project biodomes use ETFE cladding panels

The Matrimandir in Auroville is sheathed in golden discs

A dome’s foundation must always be massive and heavy due to concentrated loads

Assemblies of low‑frequency domes typically have fewer unique strut lengths than high‑frequency ones

Spaceship Earth at EPCOT is a perfect hemisphere

Geodesic domes distribute stress evenly across their surfaces

Person who coined the term “geodesic” in the context of domes

Year “The Wonder of Jena” opened (full scale)

US Patent number granted to Buckminster Fuller for the dome

Base Platonic solid most commonly used in geodesic dome design

Component name for the linear elements forming triangle edges

Connector name for the joint nodes in a dome

Cladding material used in the Eden Project for its external panels

Expo-year and city for the Montreal Biosphere

Diameter (approx.) of Spaceship Earth at EPCOT

Material often chosen for sustainable, localized dome struts in developing regions

Type of foundation made possible by uniform load distribution of a dome
