Unit 3 discussion: chapter 5, the golden ratio and the fibonacci

The Golden Ratio is often denoted by the Greek letter phi:  φ.  Its exact value is 1+52 which is approximately equal to 1.618.

In this chapter, we saw how successive quotients of the Fibonacci Numbers get closer and closer to the Golden Ratio:

11=1, 21=2, 32=1.5, 53=1.67, 85=1.6, 138=1.625, 2113=1.615, …

Many people believe that the Golden Ratio, Golden Rectangles, and the Fibonacci Numbers “appear” in the real world in places such as:

Please research at least one example of such an “appearance” in art, architecture, nature, or someplace else in the real world and post your findings.
