These photos of symmetry and order are appealing to humans and animals alike. Both in society and in the wild, organisms that are “more symmetrical” have a better chance at finding a mate than those who don't. Some speculate that this is one way of identifying a healthy partner.
The appeal of symmetry in art or inanimate objects is harder to explain. Harvard mathematician George Birkhoff developed the formula M = O/C to evaluate the aesthetic qualities of art, and even wrote a book on the topic titled Aesthetic Measure in 1933. He believed that the more ordered and the less complex something was, the more beautiful it would seem.
