There are more examples of Fibonacci numbers in nature that we haven’t covered here. … we see that each bump has bumps that form spirals, and each of those little bumps has bumps that form spirals! Hm, sounds like a fractal… The mathematical equation that describes it looks like this: Xn+2 Xn+1 + Xn Basically, each integer is the sum of the preceding two numbers. There’s a vegetable called the romanesco, closely related to broccoli, that has some pretty stunning spirals.Īnd there’s more! Not only do the bumps form spirals, but if we look closely… The first Fibonacci numbers go as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 and on to infinity. The Fibonacci Sequence is often used to arrange the petals of flowers. However, to understand the concept of the Fibonacci sequence better, here are some examples where Fibonacci sequences are used or visible in nature. Broccoli and cauliflower do, too, though it’s harder to see. As kids and students, we have all indulged in some sequencing activities. You can find more examples around your kitchen! Pineapples and artichokes also exhibit this spiral pattern. ![]() Fibonacci can also be found in pinecones. This spiraling pattern isn’t just for flowers, either. If you’re feeling intrepid, count the spirals on that one and see what you get! Check out the seed head of this sunflower: See if you can find the spirals in this one!įibonacci spirals aren’t just for flower petals. (One of each is highlighted below.) Try counting how many of each spiral are in the flower – if you’re careful, you’ll find that there are 8 in one direction and 13 in the other. No, don’t start counting all the petals on that one! What we’re looking at here is a deeper Fibonacci pattern: spirals. Here’s a different kind of Fibonacci flower: ![]() For example, there’s the classic five-petal flower:īut that’s just the tip of the iceberg! Try counting the petals on each of these! The number of petals on a flower, for instance, is usually a Fibonacci number. As can be seen from the Fibonacci sequence, each Fibonacci number is obtained by adding the two previous Fibonacci numbers together. The Great Pyramid of Giza follows the golden ratio in its. As it turns out, the numbers in the Fibonacci sequence appear in nature very frequently. What are examples of Fibonacci numbers in Architecture Many architectural structures, like the Great Pyramid, Notre Dame, Taj Mahal, Chartres Cathedral, United Nations Building, Eiffel Tower, and others, are examples that the Fibonacci numbers and the Golden ratio are applied.
