It is an irrational number often symbolized by the Greek letter “phi” ( Φ, φ ) and can be expressed by this formula: The value of the golden ratio is 0.618 or 1.618. The “golden ratio” (sometimes called the “golden mean” or “golden section”) is a fundamental geometric ratio that appears in a circumscribed equilateral triangle.
However, the statistical probability of the golden ratio’s unrelenting prevalence to such high accuracy is practically zero. Upon learning of a golden ratio related fact, most scientists will often treat it as a coincidence. He titled his work the Golden Section which is simply another name for ratio, meaning it is cut into sections of golden proportion.Emergence theory predicts a fundamental, natural phenomenon that is so strange yet so prevalent that, with no physics theory having ever explained it, has been largely ignored by the scientific establishment and often seen as the stuff of amateur scientists and hobbyists. This phenomenon is the ubiquity of the golden ratio in nature from the micro (including the Planck scale) to the macro scale. Red oak, bubinga, wenge, and maple veneer lathe-turnedĪbove is an example of a modern day artist who is interested in the golden ratio. He did an entire exploration of the human body and the ratios of the lengths of various body parts. Are the measurements in a golden proportion? You can further explore this by subdividing the rectangle formed by using her eyes as a horizontal divider. Leonardo Da Vinci called it the "divine proportion" and featured it in many of his paintings. Many artists who lived after Phidias have used this proportion. The website about the pyramid gives very extensive details on this. Its dimensions are also based on the Golden Ratio. This first example of the Great Pyramid of Giza is believed to be 4,600 years old, which was long before the Greeks. How many examples of golden rectangles can you find in the below floorplan of the Parthenon? You may want to print the diagram and measure the distances using a ruler.įollowing are more examples of art and architecture which have employed the golden rectangle. The exterior dimensions of the Parthenon in Athens, built in about 440BC, form a perfect golden rectangle. Phidias widely used the golden ratio in his works of sculpture. You can take a slide show visit to the Parthenon which is pictured above. He sculpted many things including the bands of sculpture that run above the columns of the Parthenon. There are golden rectangles throughout this structure which is found in Athens, Greece. The space between the collumns form golden rectangles. In the world of mathematics, the numeric value is called "phi", named for the Greek sculptor Phidias. This ratio was named the golden ratio by the Greeks. 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.
