About Archimedean Solids

The Archimedean solids are semi-regular polyhedra with uniform vertices but different regular polygons as faces:

  • Architecture - Geodesic structures
  • Crystallography - Complex crystal forms
  • Chemistry - Fullerenes and molecules
  • Game Design - Special dice
  • Sports - Soccer ball form
  • Art - Sculptures and design
Properties of Archimedean Solids
Semi-Regularity
All vertices are identical
Different regular face types
Construction
By truncation of Platonic solids
Or by cantellation
Chirality
Snub forms exist in two mirror forms
Left- and right-handed versions
Completeness
Exactly 13 Archimedean solids
Plus 2 prismatic families
Special Feature: The truncated icosahedron is the geometric form of a soccer ball with 12 black pentagons and 20 white hexagons.

Historical Context

Archimedes (287-212 BC): Discovered these semi-regular polyhedra as a complement to the Platonic solids.

Johannes Kepler (1619): Systematically described the Archimedean solids in "Harmonices Mundi".

Buckminster Fuller (20th century): Revolutionized architecture with geodesic domes.
