## The Golden Ratio

The golden ratio is a common ratio found in nature that can be used to create natural looking compositions in design. It is also called the Greek letter phi after the 21^{st} letter of the Greek alphabet. Since the Renaissance, the golden ratio has been used for artworks and architectures. Many artists have been studying the golden ratio because it is believed to be aesthetically pleasing. It gives the feel of proportion. The Parthenon is known as one of the oldest examples of using the golden ratio in architecture. Almost every element of the Parthenon is structured by the golden ratio. It determined the pleasing dimensional relationships between the width of the building and its height, the size of the portico and the position of the columns supporting the structure. The modern examples of the golden ratio can be found everywhere. Many companies use the golden ratio in their logo. For example, the logo of Pepsi is followed by the golden ratio by intersecting circles with a set proportion to each other.
