Pattern of Nature
This two pattern really caught my eyes. One smooth with lines and another teeth rough fern. Notice the plastic looking ferns and a tiny dried one too. The contrast does not only lies in the picture, but also the subject itself.
A recurring theme found in the biology of nature is the golden ratio, approximately 1.6180339887. Two numbers a and b keep the golden ratio when (a+b)/a = a/b, in this case a/b equals the golden ratio. It has a direct relationship to the Fibonacci numbers. This pattern was exploited by Leonardo da Vinci in his art. The Fibonacci pattern has a closed-form expression. These patterns can be seen in nature, from the spirals of flowers to the symmetry of the human body (as expressed in Da Vinci's Vitruvian Man, one of the most referenced and reproduced works of art today.
