Fibonacci Spiral

The Fibonacci spiral is a pattern that emerges from the Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. This series (0, 1, 1, 2, 3, 5, 8, 13,...) can be visualized using squares whose sides are the Fibonacci numbers. When quarter-circles are drawn within these squares, they create a spiral shape. This spiral appears in nature, such as in the arrangement of leaves, flower petals, and shells, illustrating a connection between mathematics and the natural world.
