According to Jan Tschichold : "Page proportion Kepler said of these: Geometry has two great treasures: one is the Theorem of Pythagoras, and the other the division of a line into extreme and mean ratio; the first we may compare to a measure of gold, the second we may name a precious jewel. Though it is often said that Pacioli advocated the golden ratio's application to yield pleasing, harmonious proportions, Livio points out that the interpretation has been traced to an error in , and that Pacioli actually advocated the Vitruvian system of rational proportions. The dimensions of the canvas are a golden rectangle. His most notable contribution to mathematics was a work known as Liber Abaci, which became a pivotal influence in adoption by the Europeans of the Arabic decimal system of counting over Roman numerals. He saw this system as a continuation of the long tradition of Vitruvius , Leonardo da Vinci's " Vitruvian Man ", the work of Leon Battista Alberti , and others who used the proportions of the human body to improve the appearance and function of architecture. Readers will find a detailed analysis of the role of DEMR in the Elements and of its historical implications. He also linked this number to the construction of a pentagram. Margin proportions

Numerous figures help clarify the discussions, a helpful guide explains abbreviations and symbols, and a detailed appendix defines terminology for DEMR through the ages.

This is followed by a discussion of other mathematical topics and of proposals by modern commentators concerning the relationship of these concepts to DEMR.

The study concluded that the average ratio of the two sides of the paintings studied is 1. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics.

### Golden ratio examples

Phidias BC — BC , a Greek sculptor and mathematician, studied phi and applied it to the design of sculptures for the Parthenon. Le Corbusier's faith in the mathematical order of the universe was closely bound to the golden ratio and the Fibonacci series, which he described as "rhythms apparent to the eye and clear in their relations with one another. The author then presents his own controversial views on the genesis, early development and chronology of DEMR. Kepler said of these: Geometry has two great treasures: one is the Theorem of Pythagoras, and the other the division of a line into extreme and mean ratio; the first we may compare to a measure of gold, the second we may name a precious jewel. But the suggestion that his Mona Lisa , for example, employs golden ratio proportions, is not supported by Leonardo's own writings. This work will be of interest not only to mathematicians but also to classicists, archaeologists, historians of science and anyone interested in the transmission of mathematical ideas. The dimensions of the canvas are a golden rectangle. He took suggestion of the golden ratio in human proportions to an extreme: he sectioned his model human body's height at the navel with the two sections in golden ratio, then subdivided those sections in golden ratio at the knees and throat; he used these golden ratio proportions in the Modulor system. Readers will find a detailed analysis of the role of DEMR in the Elements and of its historical implications. The company claims that this arrangement improves bass response and has applied for a patent on this innovation. This is followed by a discussion of other mathematical topics and of proposals by modern commentators concerning the relationship of these concepts to DEMR.

The coherent but rigorous presentation places mathematicians' work within the context of their time and dearly explains the historical transmission of their results. A Guide for Readers. They resound in man by an organic inevitability, the same fine inevitability which causes the tracing out of the Golden Section by children, old men, savages and the learned.
