Study Notes
The Golden Ratio
- The Golden Ratio (φ) is approximately 1.618.
- It is considered a proportion that represents beauty and perfection in mathematics, art, and nature.
Defining the Golden Ratio
- The Golden Ratio is an irrational number.
- It is achieved in a line segment when dividing the segment such that the ratio of the whole segment to the longer segment is equal to the ratio of the longer segment to the shorter segment.
Applications of the Golden Ratio
- It can be found throughout nature.
- Examples include the distribution of sunflower seeds, the cochlea of the inner ear, and galaxies.
- It is used in art as both a modern photography technique and in the works of master artists like Da Vinci and Michelangelo.
- It appears in architecture, for example in the Parthenon and the Great Pyramids.
Deriving the Golden Ratio
- Using the line segment representation and the quadratic formula, φ is about 1.618.
Historical Significance
- The Great Pyramid of Giza is one of the oldest and most prominent examples of the Golden Ratio in architecture.
- Calculations on the pyramid show a proportion matching the Golden Ratio to five decimal places.
The Parthenon
- The Golden Ratio is also seen in the Parthenon in Athens, Greece.
- The Greek sculptor Phidias, who oversaw its construction, used it in his designs.
- The Golden Ratio can be observed in the spacing of the columns as well as the overall height and width.
- Architectural studies show the structure adheres to this ratio, which the ancient Greeks found visually pleasing and an important standard for beauty.
Connection with the Fibonacci Sequence
- The Fibonacci sequence is named after Italian mathematician Leonardo Fibonacci.
- In this sequence each term is defined based on the previous terms (e.g., 0, 1, 1, 2, 3, 5, 8, 13, 21).
- When each term in the Fibonacci sequence is divided by the previous term, the resulting sequence approaches the Golden Ratio (φ).
- This connection is important for the further study of the ratio, especially as an artistic technique.
Islamic Ornamental Art
- During the Middle Ages, Islamic art featured complex geometric patterns in mosques and palaces.
- Principles of symmetry and rotational symmetry, inspired by mathematical theories, were used in Islamic ornamental designs.
- The concept of fractals was implicitly used in Islamic arts by repeating geometric patterns in different sizes.
Renaissance Perspective
- During the Renaissance, artists rediscovered linear perspective -- a mathematically based concept -- to create realistic depth in painting.
- Italian artist Leon Battista Alberti laid the foundations for mathematical perspective in painting in his book Della Pittura in 1435.
- Leonardo da Vinci used the Golden Ratio in paintings like The Last Supper and the Mona Lisa.
- Albrecht Dürer, a German artist and mathematician, created artworks based on geometric shapes and precise calculations.
Modern Art and Mathematics
- In the 20th century, artists used mathematical principles more abstractly.
- Dutch artist Mondrian used straight lines and orthogonal geometric shapes based on symmetry and balance.
- Artist Maurice Escher used geometric transformations and fractals, combining art and mathematics via symmetry and rotation.
