observed that four-ness, in fact, occurs throughout NATURE • as [IT
] naturally would in the very context of Leonardo da Vinci’s in-depth understanding that ALL [IS] in NATURE and that WE ARE a CIRCUMSTANCE of NATURE
• because NATURE always employs only the exact amount of resources and energy necessary for ANY TASK, the majority of natural construction [IS] predicated upon the tetrahedron and its minimal FOUR ITEMS or POINTS. To better understand why four [IS] so significant, Fuller considered another geometrical phenomenon, the most efficient , stable configuration in which four identical balls can be closely packed. Three balls on a flat surface come together naturally in a triangular formation with each ball touching the other two at a single point. To completely stabilise that configuration the fourth ball nests in the indentation provided by the other three as seen in my collage below.
This modest structure provides another demonstration that Fuller employed to illuminate a metaphysical phenomenon using a physical artefact. By connecting the the centres of this most efficient means of packing a fundamental component of UNIVERSE (i.e., the sphere), the essential regular tetrahedron is fabricated. The fact of which Leonardo da Vinci undoubtedly understood.
