Another example is fractals, which are never-ending patterns that repeat at different scales.
Take a look at a snowflake, a broccoli’s Romanesque head, or the coastline of a country—
these all have fractal-like qualities. The idea of self-similarity (where smaller parts of the
object resemble the whole) is a direct application of math in real life.
And then there’s symmetry, which is fundamental to both math and nature. Symmetry is
what makes a butterfly’s wings look so balanced and identical, or how a starfish has five
arms that radiate from a central point. In mathematics, symmetry is often explored through
shapes and equations, but in nature, it's an expression of optimal design. Evolution seems to
favor symmetrical patterns because they can often be more efficient.
