Since we are good at finding patterns, it may be the case that we are forcing the golden ratio on these architectures, and the original designers did not intend it. However, it should be remembered that We cannot achieve the perfect golden ratio as it is an irrational number. Some other examples are the Taj Mahal and Notre Damn etc. Similarly, it is argued that the pyramids of Giza also contain the golden ratio as the basis of their design. It is also argued that the golden ratio has appeared many times over the centuries in the design of famous buildings and art masterpieces.įor example, We can find the golden ratio many times in the famous Parthenon columns. Many people believe that the golden ratio is aesthetically pleasing, and artistic designs should follow the golden ratio. We leave this matter to the personal preference of the reader. How much of the golden ratio is actually present in nature and how much we force in on nature is subjective and controversial. These structures are indeed similar to the golden spiral mentioned above however, they do not strictly follow the mathematics of the golden spiral. However, again we must remember that many ratios between 1 and 2 can be found in the human body, and if we enumerate them all, some are bound to be close to the golden ratio while others would be quite off.įinally, the spiraling structure of the arms of the galaxy and the nautilus shell is also quoted as examples of the golden ratio in nature. In the human body, the ratio of the height of the naval to the total height is also close to the golden ratio. Also, all types of ratios can be found in any given human face. But, again, this is highly subjective, and there is no uniform consensus on what constitutes an ideal human face. It is also claimed that the ideal or perfect human face follows the golden ratio. Hence, any claim that the golden ratio is some fundamental building block of nature is not exactly valid. However, we must remember that many plants and flowers do not follow this pattern. We can see this pattern in Elm, Cherry almond, etc. For instance, in many cases, the leaves on the stem of a plant grow in a spiraling, helical pattern, and if we count the number of turns and number of leaves, we usually get a Fibonacci number. Most readily observable is the spiraling structure and Fibonacci sequence found in various trees and flowers. There are many natural phenomena where the golden ratio appears rather unexpectedly. Such a triangle is called the Kelper triangle, and we show it below: Two quantities $a$ and $b$ with $a > b$ are said to be in golden ratio if $\dfrac$ and perpendicular equal to 1, it will be a right-angled triangle. Moreover, it is an interesting concept mathematically and from an aesthetic and sometimes metaphysical point of view. This method using a continued fraction, which is one of those terrifying constructions illustrated in Figure 2.The golden ratio is an intriguing mathematical relation between two quantities. And remember, some systems require that you link in the math library ( m) for the sqrt() function to behave properly.Ī second way exists to calculate the golden ratio. This expression matches the one used to determine the value of φ, as shown earlier. The math.h header file is required for the sqrt() function, used in the equation at Line 8. If your code demands it, you must perform some math, as shown in the following example: 2020_11_14-Lesson.c Unlike π, e, √2, and other values, the golden ratio doesn’t exist as a defined constant in the math.h header file. Mathematicians using brains far more massive than my own have determined, by using the quadratic formula and other scary words, that this equation works out like this: The expression to describe the relationship between lengths a and b is written like this: An animation showing the relationship between ‘a’ and ‘b’ relative to each other.
