Symmetry is encountered often in nature, whether that’s in the patterns of a beautiful flower, the structure of a crystal or the arrangement of cells in a honeycomb.

In fact, you might argue that science is essentially about detecting, describing and explaining the patterns and symmetries found in nature, beginning with sequences like the rising and setting of the sun and moon and the rotation of seasons, and developing into what modern science can tell us about the world today.
