Natural shapes are developed through specific processes that follow mathematical principles. Hidden mathematical laws and secret numbers are found at the common border of dynamics, geometry, and arithmetic. The combination of the words "mathematics" and "beauty" may surprise us. Most people imagine mathematics as endless pages with complex "equations" - not a beautiful image, I understand. However, the beauty of mathematics does not lie in symbolism, but in its ideas. Mathematics is a systematic - conscious - technique that we invented in order to exploit our sharp eye whenever we seek shapes. Therefore, there is no contradiction; the bond between mathematics and beauty is very strong. This wonderful book offers us an enlightening and warm image of how the seemingly cold laws of mathematics find expression in the beauty of nature.
