The secret of the man of Vitruvius of Vinci pierced by a dentist?

The secret key of Vitruvian man Would she have just been discovered by a dentist? Moreover, For more than 500 years. However, The geometric system used by Leonardo da Vinci (1452–1519) To establish the precise relationship between the circle and the square in this famous pen drawing, ink and wash on paper made around 1490, is remained a mystery. Moreover, Until the publication on June 26. Similarly, in the academic journal Journal of Mathematics and the Arts (resumed on July 18 by Sciencealert), of a Interesting hypothesis formulated by a London dentistRory Mac Sweeney…

The famous drawing represents the Ideal proportions of the human bodyperfectly inscribed in a circle, the center of which corresponds to its navel, and in a square, in the center of which its genitals are located. Consequently, Kept at the Gallerie Dell’accademia in Venice. Moreover, it is become secret man vitruvius vinci pierced the emblem of Renaissance humanismwhich places man at the center of the universe, as “measure of everything”, and seeks to study the world from all its seams to understand how it works.

To realize it. Moreover, Leonardo da Vinci looked at the treaty The architecturewritten in i^is century BC by a Roman architect, Marcus Vitruvius Pollio dit Vitruve, who said that a human being with perfect proportions could Register to the nearest millimeterand simultaneously, in a circle and in a square. Nevertheless, What the Italian artist and inventor of the Renaissance managed to draw. Therefore, But what mathematical system did he use to get there?

A triangle question

Many theories have been put forward over the years. The most popular being that Léonard would have relied on the name d’Ornicknamed « la divine proportion »present in nature. consisting of a proportion between two lengths, equal to 1.618 – proportion that is obtained secret man vitruvius vinci pierced when the two lengths in question. A and B, can form the following equation: (a + b) / a = a / b. Except that this measure does not apply exactly to Vitruvian man : we observe on the drawing a deviation. of more than 2 % compared to this figureincompatible with Léonard’s usual precision!

What if the solution had been explained to us from the start by the scientist himself? It is by reading Leonard’s annotations associated with the drawing that Dentist Rory Mac Sweeney Has the click: “If you open your legs enough. raise your hands enough for your extensive fingers touching the line from the top of your head, the space between the legs will be a equilateral triangle “Written from Vinci.

The researcher then drawn an equilateral triangle connecting the navel. both feet of Vitruvian manthen reproduced this form six times Around the navel To form a hexagon F perfect in the circle. He then found that the relationship between both sides of this equilateral triangle was approximately 1.64 – either the same measured relationship between the side of the square and the radius of the circle.

Anticipation by vinci of future anatomical discoveries

“It reveals that Vitruvian man De Léonard contains geometric principles that anticipate modern understanding of optimal biological architecture. »»

But that’s not all: Rory Mac Sweeney realizes that this equilateral triangle correspond au triangle de Bonwilldiscovered. documented in 1864, drawn between the middle of the incisors and the joints of the mandibles, which shows the Ideal jaw positioning. Because the relationship between the two sides of this triangle is to 1. 633or a measure practically equal to that present in Vitruvian man.

Rory Mac Sweeney adds that this report also appears “in the optimal stack of spheres. the structures to tensegrity, and the Vector Equilibrium by Buckminster Fuller”. Also says «Cubozzere»the latter is the only geometric structure whose interior. exterior lengths are equalwhich gives it a perfect vector balance. Finally, this 1.64 report is also found in several modern anatomical measurements exclusively present in the human body. and in particular in the architecture of the skull.

“It reveals that Vitruvian man de Léonard contains geometric principles which anticipate modern understanding of optimal biological architecture […]and that there are constant mathematical relationships encoded in biological forms. ”concludes the dentist; Before adding that this work “testifies to the insight of Leonardo, who had understood, centuries before modern science could validate them, of fundamental truths on the mathematical nature of the worldthat human proportions are a reflection of mathematical principles which register the secret man vitruvius vinci pierced optimal spatial organization throughout the universe ”. A attractive theorywelcomed with interest by the scientific press since its unveiling.
