(6) Beauty of the Golden RatioDec 1, 2012
The Golden Ratio, 1.61803, is the ratio a /b which is such that a/b = (a+ b)/a. The Golden Ratio is supposed to be the most pleasing shape to the human eye and is found in many things such as the ancient Pyramids, the Parthenon, the Venus of Melos, and the art works like Mona Lisa and Japanese woodblock prints. The ratio of the slant height of King Khufu's pyramid to half the base is said to be 1.61846. The error is 0.03%, comparing with the Golden Ratio. It is surprising that the ancient Egyptians adopted the highly accurate Golden Ratio about 4500 years ago. In addition, the Golden Ratio is frequently found in the natural world. Some examples are: the ratio of the total body height to the navel height, the ratio of the length of the face to the width of the face, and the ratio that is found in snails or plants. If you can find beauty in nature or painting, the Golden Ratio is hidden in them somewhere. Why don't you try to find an example of the Golden Ratio?
