The seed head of the common dandelion is anything but common. Within the shape and patterns of its seeds are lessons in geometry and physics. Close observations will reveal geometric patterns that can lead a curious mind to identify spiraling patterns known as the Fibonacci sequence. Looking closely and learning how the Fibonacci sequence and Golden Ratio are closely tied can spotlight a mathematical foundation found throughout nature. Learn the sequence and see where you can find it in other places, including pinecones, the shell of a snail, sunflowers, and of course, dandelion flowers and seed heads.
