Transcript of The Golden Ratio

The Italians Luca Pacioli The Ancient Greeks The Parthenon What is it? Music Contemporary Art Salvador Dali Twitter Christina Cooper The Golden Ratio Value Explaination The ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one Markosky "None of these authors is bothered by the fact that parts of the Parthenon are outside the golden rectangle." -Markosky (1992) Leonardo Da Vinci De Divina Proportione Illustrated book for Pacioli
First to call it golden ratio Da Vinci's St. Jerome in the Wilderness Date St. Jerome Painted:
1480 Date Da Vinci learned about Pacioli's thoughts on golden ratio:
1493 Haydn's Quartet Op. 1 No. 3, in D Major First movement
Total bars: 88
Theoretical ratios: 88/55/34/21/14/8 Mozart's Symphony in G Minor Highest note: measure 62
Lowest note: measure 38
Measures between highest and lowest: 24 "The cassocks of the priests...form a repeated series of pentagons, and the overall dimensions of the canvas are those of a golden section rectangle. Dominating the upper part of the work...is a giant three-dimensional version of one of Leonardo's drawings for Pacioli." (Dave) Dodecahedrons Nature "The nautilus shell is definitely not in the shape of a golden ratio. Anyone with access to such a shell can see immediately that the ratio is somewhere between 4:3." (Falbo, 2005) "One of the luxuries of the artist is that art is validated by the work itself and does not require subservience to the rigors of mathematics or logical proof." (Evans, 1992, p. 304) Nautilus Shells
