__Golden Ratio in Human Body__

In this video, I learned many interesting facts. If you divide a number by the number before it, you attain numbers very close to one another. After the thirteenth number, the number is fixed and known as the Golden Ratio which is 1.618. Leonardo da Vinci used the Golden Ratio in his designs. Also, architect Le Corbusier used the number for his designs. There are many features that you must measure to see how beautiful a person is overall, even the total width over the front teeth over the health equal to the Golden Ratio. The Golden Ratio is even found in the structure of the lung and in our DNA. The Golden Ratio is found in animals, paintings, buildings, and so much more.

__The Golden Ratio and Beauty in Architecture__

The Golden Ratio was used in ancient times. One of the Seven World Wonders, the Great Pyramid in Giza, Egypt, was formed using the Golden Ratio. Therefore, the Ancient Egyptians and Greeks had knowledge about the Golden Ratio. Renaissance artists used the Golden Ratio as well, in example of Notre Dame. The Parthenon has exterior dimensions that equal to the Golden Ratio. The United Nation building has the Golden Ratio in the width of the building compared with the height of every ten floors.

__The Golden Ratio Revisited__

The Golden Ratio is a mathematical formula made from Eucid, who is also known as the "Father of Geometry". It is an universal way of defining beauty. That is why some objects are aesthetical pleasing while other are not. The ratio is evident in the painting, "Vitruvian Man", by Leonardo da Vinci. It is also evident in Mona Lisa. It is present in book design, music, and Mother Nature. Adolf Zeising discovered the Golden Ratio in the branches along the stems of plants and veins in leave. A flower or a pineapple is appealing because of the Golden Ratio. It is present in almost everything.

__Nature by Numbers__

Fibonacci wanted to know how many rabbits would be produced in a year. He assumed that starting with January, each new month the rabbits would give birth to a new pair. He noticed a pattern that the rabbits were increasing in a sequence each month. This resulted in the Fibonacci numbers. The structure of flowers are based off the Fibonacci number. Sunflower have 33, 55, or 89 petals, which is a Golden Ratio. Organic growth is stimulated by the Fibonacci number. The Greeks believed that the rectangle had a mathematical beauty.

__Response and Reflection__

Overall, the information I learned was very interesting. I think it is amazing how these numbers determine how appealing something could be to the eye, such as things found in Mother Nature. In all honesty, I believe that Fibonacci's numbers do play a role in beauty. However, I believe it doesn't play a major role. For something to be appealing to one's eye, color and such plays a role. It is not just about size. Also, everyone has a different preference when it comes to determining what is beautiful. The "Golden Ratio" is very interesting and valid, but only in a small role of beauty.
