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… A wonderful introduction to one of the most beautiful connections between mathematics and the natural worldthe Fibonacci sequencethrough a series of stunning. 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… Broccoli and cauliflower do, too, though it’s harder to see. 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: The sequence can be observed in the arrangement of leaves on a stem, the branching of trees, and the spiral patterns of shells and galaxies. 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 significance of the Fibonacci Sequence lies in its prevalence in nature and its applications in various fields, including mathematics, science, art, and finance. The number of petals on a flower, for instance, is usually a Fibonacci number. These numbers, 34 and 21, are numbers in the Fibonacci series, and their ratio 1.6190476 closely approximates Phi, 1.6180339.įollow our Number Sense blog for more math activities, or find a Mathnasium tutor near you for additional help and information.As it turns out, the numbers in the Fibonacci sequence appear in nature very frequently. The DNA molecule measures 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral. DNA moleculesĮven the microscopic realm is not immune to Fibonacci. When a hawk approaches its prey, its sharpest view is at an angle to their direction of flight - an angle that's the same as the spiral's pitch. And as noted, bee physiology also follows along the Golden Curve rather nicely. Following the same pattern, females have 2, 3, 5, 8, 13, and so on. Thus, when it comes to the family tree, males have 2, 3, 5, and 8 grandparents, great-grandparents, gr-gr-grandparents, and gr-gr-gr-grandparents respectively. 1 Extend, create, and generalize growing and shrinking numeric and geometric patterns (including multiplication patterns). Males have one parent (a female), whereas females have two (a female and male). In addition, the family tree of honey bees also follows the familiar pattern. The answer is typically something very close to 1.618. The most profound example is by dividing the number of females in a colony by the number of males (females always outnumber males). Speaking of honey bees, they follow Fibonacci in other interesting ways.
