Why Bees Beat Engineers

Bees build hexagonal honeycombs because the hexagon is the optimal shape for enclosing area with the least wall material. They solved this instinctively, through natural selection, ages before anyone could write the theorem down.

The same shape now shows up wherever efficiency matters: carbon nanotubes, soap-bubble foams, graphene sheets, and aerospace panels. The math of area-per-perimeter efficiency explains why hexagons dominate any system trying to pack regions tightly without waste.
