Numbers also play a significant role in nature. This is evident in the case of crystals, the only naturally occurring Platonic bodies. The appearance of sunflowers, pine cones or cauliflowers is determined by a mathematical sequence known as the Fibonacci sequence. It forms the basis of the “golden section”, which not only determines the construction of ancient buildings, but also the nautilus shell. But numbers are also significant in the case of other animals, and we’re not just talking about honeycombs and the compound eyes of insects here.
