Fractals are geometric forms that repeat similar patterns at different scales. When zooming in on a fractal, the same pattern appears as when viewing it as a whole. Fractals can be found throughout nature in structures like trees, ferns, lightning, clouds, coastlines, and cauliflower. Using fractal geometry allows for more precise measurements of natural phenomena like coastline length and cloud movement that were previously difficult to quantify. Fractals have applications in diverse fields including wireless communication, movies, medicine, and biology.
