Golden Ratio Reliability
Problem/Question
How common is the Golden Ratio in famous art?
Hypothesis/Conjecture
Most famous paintings will show the Golden Ratio, with Van Gogh having more instances of the Golden Ratio than Monet or Picasso. I think that Van Gogh will have the most because his paintings are popular with a lot of people.
What is the Golden Ratio?
The Golden Ratio is said to result in the most pleasing shape, and is found by using the formula a/b = a+b/a. The formula is equal to about 1.618, also known as Phi (𝛗). Like Pi, it never repeats or terminates, making it an irrational number. It is not a shape, but a comparison to the length and width. Phi is connected with the Fibonacci Sequence, which is also found in nature.
Materials
Dimensions of most famous paintings according to websites (Starry Night, Cafe Terrace at Night, Painter of Sunflowers, Impression, Sunrise, Woman With a Parsol - Madame Monet and Her Son, The Artist’s Garden At Giverny, The Weeping Woman, The Old Guitarist, Girl Before a Mirror)
Calculator
Scissors
Paper to cut and to record data
Yellow-Van Gogh
Blue-Monet
Green-Picasso
Procedure
Black square width ÷ blue rectangle width
Data Table
Starry Night | No Golden Ratio, but the star/swirls have (or are based off) the Golden Spiral (the spiral on the background on page 4 that can be made by making more golden rectangles in a already golden rectangle) |
Cafe Terrace at Night | No Golden Ratio |
Painter of Sunflowers | No Golden Ratio |
Impression, Sunrise | No Golden Ratio |
Woman With a Parasol-Madame Monet and Her Son | No, but the people in the painting reside in a Golden Section (an area of the painting that is golden, but the whole painting is not golden) |
The Artist’s Garden at Giverny | No Golden Ratio |
The Weeping Woman | No Golden Ratio |
The Old Guitarist | No Golden Ratio |
Girl Before a Mirror | No Golden Ratio |
Van Gogh=Orange
Monet=Blue
Picasso=Green
Conclusion and Proofs
My hypothesis was rejected.
Phi showed up 0 out of 9 times that I calculated, but Monet and Van Gogh had paintings with the Golden Ratio, however it was not in the dimensions of the painting.
Real World Connection
This project relates to the real world because we see the golden ratio everyday and you are not completely aware of it. Your brain subconsciously notices it and thinks, hmmm, this looks nice, and you then enjoy looking at it, but you never consciously know. A lot of visually pleasing things follow the Golden Ratio.*
*Hurricanes follow the Golden Ratio,
we hear a lot about them! So do
tornadoes, whirlpools, and tsunamis.
