1, 1, 2, 3, 5, 8, 13, 21, 34 … this is the beginning of the Fibonacci sequence, an infinite string of numbers named after, but not invented by, the 13th century Italian mathematician Fibonacci. It may seem like a piece of mathematical arcania, but the Fibonacci sequence is found to appear, time and time again, among the structures of the natural world and even in the products of human culture. From the Parthenon to pine cones, from the petals on a sunflower to the paintings of Leonardo da Vinci, the Fibonacci sequence seems to be written into the world around us.
