Every year on 11/23, we celebrate one of the most famous patterns in mathematics — the Fibonacci sequence. What is the Fibonacci sequence? It’s a list of numbers where each number is the sum of the two before it: 1, 1, 2, 3, 5, 8, 13, 21… This simple rule creates a pattern that grows in a beautifully balanced way. The Golden Rectangle & Golden Spiral When squares with Fibonacci side lengths are arranged together, they form a golden rectangle — a shape whose proportions stay the same as it grows. If you draw a smooth curve through the corners of these squares, you get the golden spiral, a shape that expands outward while keeping the same proportions. This spiral models growth found in many natural forms. Where do we see it in nature? The Fibonacci sequence is everywhere! • Sunflower seeds grow in spirals that match Fibonacci numbers. • Pinecones have spiral patterns that follow the sequence. • Nautilus shells show growth close to the golden spiral. • Hurricanes and galaxies swirl in...
