Origin and History of the Golden Ratio
The golden ratio's origins can be traced to ancient Greece, where it was known as "the divine proportion." The mathematician Euclid is credited with the first recorded definition of the golden ratio in his work "Elements." Euclid described it as the division of a line into two unequal parts, where the ratio of the whole line to the longer part is equal to the ratio of the longer part to the shorter part. This simple yet profound concept laid the foundation for centuries of mathematical exploration.
Throughout history, the golden ratio has appeared in various cultures and contexts. The ancient Egyptians are believed to have used the golden ratio in the design of the Pyramids of Giza, while the ancient Greeks incorporated it into their sculptures and architecture.

Today, the golden ratio continues to influence art, design, and architecture, serving as a testament to its timeless appeal.
One of the most well-known historical references to the golden ratio is the Fibonacci sequence, named after the Italian mathematician Leonardo of Pisa, also known as Fibonacci. In the 13th century, Fibonacci introduced the sequence to the Western world through his book "Liber Abaci." The Fibonacci sequence, where each number is the sum of the two preceding numbers, is closely related to the golden ratio. As the sequence progresses, the ratio of consecutive Fibonacci numbers approaches the golden ratio, highlighting its significance in mathematical patterns.
Mathematical Definition and Properties
The golden ratio is an irrational number, meaning it cannot be expressed as a simple fraction. Its decimal representation is non-repeating and infinite, approximately equal to 1.6180339887. Mathematically, the golden ratio is defined as follows: if a line segment is divided into two parts, a and b, where a is the longer part and b is the shorter part, the golden ratio is achieved when (a+b)/a = a/b = φ.
One of the remarkable properties of the golden ratio is its self-similarity. When a golden rectangle (a rectangle whose sides are in the proportion of the golden ratio) is divided into a square and a smaller rectangle, the smaller rectangle is also a golden rectangle. This infinite recursive pattern is visually represented in the golden spiral, a logarithmic spiral that grows outward by a factor of the golden ratio for every quarter turn.
The golden ratio also exhibits fascinating mathematical relationships with other numbers and geometric shapes. It is connected to the Fibonacci sequence, where the ratio of successive Fibonacci numbers converges to the golden ratio as the sequence progresses. Additionally, the golden ratio appears in the geometry of regular pentagons and pentagrams, where the ratio of the diagonal to the side length is the golden ratio.
