Honeybees communicate the location of food sources through an intricate waggle dance that relies on mathematics. The dance uses the positions of the sun and gravity to indicate direction and distance in a way that allows other bees to efficiently find the food. Hexagonal tiling is the most efficient shape for honeycomb cell construction because hexagons use the least amount of material while providing strength and stability. Mathematical formulas like Euler's help explain relationships in the hexagonal structures bees create.
