The golden ratio, also known as the golden section or the divine proportion, is a mathematical concept that has captivated the minds of artists, architects, and mathematicians for centuries. The ratio, denoted by the Greek letter phi (Ï†), is approximately equal to 1.618 and is found in many natural and man-made objects.

The golden ratio can be described as the ratio of the smaller part of a whole to the larger part, or the ratio of the larger part to the whole. In mathematical terms, this can be expressed as a+b is to a as a is to b, or a/b = (a+b)/a.

One of the earliest known references to the golden ratio can be found in the writings of the ancient Greeks. The mathematician Euclid described the golden ratio as "the most beautiful of all proportions" in his work "Elements." The golden ratio also appears in the work of the ancient Greek sculptor Phidias, who used it to create aesthetically pleasing works of art.

The golden ratio has been used throughout history in a variety of contexts. In art, the golden ratio has been used to create compositions that are aesthetically pleasing to the eye. Architects have used the golden ratio to design buildings that are harmonious and pleasing to look at. The golden ratio has also been used in the design of websites and other digital media, as it is thought to be aesthetically pleasing to the human eye.

One of the most famous examples of the use of the golden ratio can be found in the design of the Parthenon in Athens. The Parthenon is considered to be a prime example of classical architecture, and its design incorporates the golden ratio in many ways. The length and width of the temple, as well as the height of the columns, all follow the golden ratio.

The golden ratio has also been found to occur in nature. The spiral patterns found in seashells and pinecones, for example, are believed to be based on the golden ratio. The human body also exhibits the golden ratio, with the ratio of the length of the hand to the length of the arm being approximately equal to the golden ratio.

Despite its widespread use and recognition, the golden ratio has also been the subject of some controversy. Some have argued that the golden ratio is overrated and that its importance has been exaggerated. Others have claimed that the golden ratio is not as common in nature as some believe.

In conclusion, the golden ratio is a mathematical concept that has fascinated people for centuries. It has been used in art, architecture, and design to create aesthetically pleasing compositions and has been found in a variety of natural objects. While it has been the subject of some controversy, the golden ratio remains an important and widely recognized concept.

In other words, no matter how hard we search, we cannot find some common measure that is contained, let's say, 31 times in AC and 19 times in CB. We subject the unlooked for and unimagined, to the mathematical formulae of the schools. Indeed, some authoritative books on the history of mathematics, like Frankois Lasserre's The Birth of Mathematics in the Age of Plato, and Carl B. It tells the human story of numerous phi-fixated individuals, including the followers of Pythagoras who believed that this proportion revealed the hand of God; astronomer Johannes Kepler, who saw phi as the greatest treasure of geometry; such Renaissance thinkers as mathematician Leonardo Fibonacci of Pisa; and such masters of the modern world as Goethe, Cezanne, Bartok, and physicist Roger Penrose. It's hard not to feel inspired and even unsettled by the hidden order Livio reveals.
