What do hurricanes and pine cones have in common?
Happy Fibonacci Day! November 23 is Fibonacci Day, because the numbers are in the Fibonacci sequence of 1, 1, 2, 3. So when written in MM/DD format it forms the sequence that can be charted out into a pattern. The Fibonacci sequence appears in many patterns of nature like the branching in trees, leaves on a stem, family trees of honeybees, flower petals, spirals of a sunflower and so on. The sequence is named for Leonardo Fibonacci, a Medieval mathematician who lived in Pisa from around 1170 -1250 ad. x Starting with 1, 1, 2, 3, 5, the Fibonacci sequence is created by adding up the two previous numbers to get the next one. The pattern is made up of numbers that sum the previous two numbers before them — 1, 1, 2, 3, 5, 8, 13 — and so on. The sequence is used in computing, stock trading, and architecture and design. Once we discovered the sequence, it started showing up everywhere. Nature is full of Fibonacci patterns, from DNA to hurricanes, leading some to dub the Fibonacci sequence
