As an expert in the field of mathematics and history, I can provide you with a detailed account of the discovery of the golden mean, a concept that has fascinated thinkers for centuries due to its aesthetic and mathematical properties.
The golden mean, often referred to as the golden ratio, is a mathematical constant that is approximately equal to 1.61803 39887 49894 84820. This constant is denoted by the Greek letter φ (phi) and is found in various natural phenomena, art, architecture, and even in the proportions of the human body.
The concept of the golden ratio has been known to humanity for a very long time, but the question of who discovered it is not straightforward. The golden ratio has been observed and used in various cultures throughout history, and it was not the product of a single discovery by an individual. However, the formal recognition and study of the golden ratio as we understand it today can be attributed to the ancient Greeks.
In ancient Greece, the golden ratio was known as the divine proportion and was considered to represent beauty and harmony. The Greeks believed that this ratio was the key to creating aesthetically pleasing designs and structures. This belief was based on the observation that rectangles with proportions close to the golden ratio were the most pleasing to the eye.
The Greek sculptor Phidias, who lived around the 5th century BCE, is sometimes associated with the golden ratio because of his work on the statue of Zeus at Olympia, which is believed to have incorporated the divine proportion. However, it is important to note that while Phidias may have used the golden ratio in his work, he was not the one who discovered it.
The formal mathematical study of the golden ratio began with the Greek mathematicians of the classical period.
Euclid of Alexandria, in his work "Elements," written around 300 BCE, provided a mathematical description of the golden ratio. Euclid's work laid the foundation for the mathematical understanding of the golden ratio and its properties.
In "Elements," Euclid discussed a special type of rectangle, now known as the golden rectangle. A golden rectangle is a rectangle whose sides are in the golden ratio to each other. Euclid showed that if you start with a square and inscribe a larger square within it, the remaining rectangle is a golden rectangle. This construction leads to the definition of the golden ratio as the positive solution to the quadratic equation \( x^2 - x - 1 = 0 \), which simplifies to \( x = \frac{1 + \sqrt{5}}{2} \) or \( x = \phi \).
The golden ratio has also been associated with the Fibonacci sequence, a series of numbers in which each number is the sum of the two preceding ones, starting from 0 and 1. As the numbers in the Fibonacci sequence get larger, the ratio of consecutive Fibonacci numbers approaches the golden ratio. This connection was first made by the Italian mathematician Leonardo Fibonacci in the 13th century, but the sequence itself was known earlier in Indian mathematics.
Throughout history, the golden ratio has been celebrated for its aesthetic qualities and has been used in various fields, from architecture to art to design. It has been associated with the works of great artists such as Leonardo da Vinci, who is said to have used the golden ratio in his paintings, most notably in the composition of the "Mona Lisa."
In conclusion, while the golden ratio has been observed and used by various cultures throughout history, its formal mathematical study and recognition as a concept distinct from other proportions can be attributed to the ancient Greeks, particularly Euclid. The golden ratio, with its unique mathematical properties and its presence in nature and human creations, continues to captivate and inspire mathematicians, artists, and designers to this day.

Throughout history, the ratio for length to width of rectangles of 1.61803 39887 49894 84820 has been considered the most pleasing to the eye. This ratio was named the golden ratio by the Greeks. In the world of mathematics, the numeric value is called "phi", named for the Greek sculptor Phidias.
