Geneticist claims key breakthrough in 'real Da Vinci Code'
A geneticist believes he has cracked the real Da Vinci Code in connection with one of the master painter's artworks that has stumped experts for 500 years.
Five centuries ago, Rennaissance artist Leonardo da Vinci scribbled down his vision of what the perfectly proportioned male body would look like. Known as the Vitruvian Man, the simple sketch is considered one of the most important anatomical drawings in the world.
But its references to art, maths and the human body have remained a mystery to scientists for years. London-based dentist and trained geneticist Dr Rory Mac Sweeney believes he has the answer to how the Italian master placed the male in perfect proportions inside both a square and a circle.
He said the key to unlocking the geometric code is the triangle that sits between the man's legs, which da Vinci explained himself in manuscripts that came with the sketch.
Rather than a random shape, it corresponds to Bonwill's triangle - which is also used in dental anatomy to measure the optimal performance of the human jaw.
But having been drawn hundreds of years before the birth of modern science, it seems incredible to suggest he understood the ideal design of the human body back then, according to Dr Sweeney.
The triangle used to construct the Vitruvian produces a specific ratio between the size of the other shapes, 1.634. This ratio is incredibly close to the "special blueprint number", which appears in nature and is said to be used to construct the most-efficient structures, like the human jaw, human skull, or the atomic structure of crystals.
"We've all been looking for a complicated answer, but the key was in Leonardo's own words," Dr Sweeney, a graduated of the School of Dental Science at Trinity College in Dublin.
"He was pointing to this triangle all along. What's truly amazing is that this one drawing encapsulates a universal rule of design.
"It shows that the same "blueprint" nature uses for efficient design is at work in the ideal human body.
"Leonardo knew, or sensed, that our bodies are built with the same mathematical elegance as the universe around us."
He considers the artowkr a piece of "scientific genius that was centuries ahead of its time".

Dentist cracks mystery of world famous Da Vinci drawing after 500 years
It is one of the most famous – and mystifying – drawings in human history. Leonardo da Vinci's Vitruvian Man was the attempt by the famous Italian artist to construct the perfectly proportioned male body 500 years ago. But mathematicians have spent years trying to crack the question of how he was able to place the human figure inside a circle and a square. Now, a London-based dentist has uncovered a hidden detail in Da Vinci's masterpiece, which he says reveals the answer. Dr Rory Mac Sweeney points to an equilateral triangle 'hidden in plain sight' in the Italian's notes, which lays the foundation of the drawing's perfect proportionality. The triangle, found between the man's legs, 'isn't just a random shape', Dr Sweeney says, but corresponds to a little-known concept called Bonwill's triangle. Bonwill's triangle is a concept in dental anatomy which is used to understand how human jaws work. The imaginary triangle connects the left and right jaw joints with the spot between your two bottom front teeth – each side is four inches long. The fact that da Vinci was using this shape in a drawing sketched in 1490 drawing reveals his genius understanding of the human body centuries before modern science came along, Dr Sweeney argues. Here is where it gets a little mathsy. When you use one of these triangles in the Vitruvian Man, you can calculate a ratio between the size of the square and the circle in the famous drawing. That ratio is 1.64, which is almost identical to a very important number – 1.6333. That number is called the 'special blueprint number', which you can find everywhere in the most efficient structures in nature. That number pops up everywhere – even stacking oranges – because it governs the tightest way to pack spheres, among other things. Dr Sweeney, who graduated from the School of Dental Science at Trinity College in Dublin, said: 'We've all been looking for a complicated answer, but the key was in Leonardo's own words. 'He was pointing to this triangle all along. What's truly amazing is that this one drawing encapsulates a universal rule of design. 'It shows that the same 'blueprint' nature uses for efficient design is at work in the ideal human body. 'Leonardo knew, or sensed, that our bodies are built with the same mathematical elegance as the universe around us.' The dentist argues his discovery shows the Vitruvian Man is not a beautiful drawing, but a work of 'scientific genius that was centuries ahead of its time'. Sweeney believes he has solved the riddle first set by Roman architect Marcus Vitruvius Pollio hundreds of years ago. He said the human body has harmonious proportions, and theorised it could fit perfectly inside a circle and a square, but never outlined how that could be done. Da Vinci then came long and drew exactly that, but never explained how. Sweeney believes his theory puts to bed centuries of speculation as to what measurements the Italian polymath used. The study, published in the Journal of Mathematics and the Arts, reads: 'For over 500 years, Leonardo da Vinci's geometric system for establishing the precise relationship between the circle and square in his Vitruvian Man drawing has remained a mystery. 'This paper demonstrates that Leonardo's explicit textual reference to 'an equilateral triangle' between the figure's legs provides his construction method and reveals the anatomical foundation for his proportional choices. 'The analysis shows that Leonardo's equilateral triangle corresponds to Bonwill's triangle in dental anatomy – the foundational geometric relationship governing optimal human jaw function.' Not long after the Vitruvian Man came into being, Da Vinci painted one of the most important religious paintings ever – The Last Supper. More Trending The depiction of Jesus and his disciples was then followed by the most famous artwork of them all, the Mona Lisa, in the early 1500s. The painting attracts millions of visitors annually at the Louvre Museum in Paris alone. Other than his artwork, Da Vinci is known for his vast array of talents. He was also a sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer.

Geneticist claims key breakthrough in 'real Da Vinci Code'
The Vitruvian Man - a famous drawing by Rennaissance artist Leonardo da Vinci in 1490 - depicts a nude male figure with his arms and legs spread inside both a circle and a square A geneticist believes he has cracked the real Da Vinci Code in connection with one of the master painter's artworks that has stumped experts for 500 years.

The real Da Vinci Code is SOLVED after 500 years: Dentist cracks geometric secret hidden in Vitruvian Man
Some 500 years ago, Leonardo da Vinci sketched what he believed was the perfectly proportioned male body. The drawing, called the Vitruvian Man, is one of the most famous anatomical drawings in the world. The complex interplay of art, mathematics and human anatomy has puzzled scientists for hundreds of years. But now, a London-based dentist claims to have worked out the secret to how da Vinci perfectly placed the human figure inside a circle and a square. Dr Rory Mac Sweeney, a qualified dentist with a degree in genetics, says the key to unlocking the drawing's geometric code lies in the use of an 'equilateral triangle' between the man's legs, mentioned in manuscript notes that accompany the drawing. The researcher discovered this isn't just a random shape – and in fact reflects the same design blueprint frequently found in nature. Analysis reveals this shape corresponds to Bonwill's triangle, an imaginary equilateral triangle in dental anatomy that governs the optimal performance of the human jaw. This suggests da Vinci understood the ideal design of the human body centuries before modern science, Dr Sweeney said. Dr Sweeney said the key to unlocking the drawing's geometric code lies in the specific mention of an 'equilateral triangle' drawn between the man's legs (left) which corresponds to a design blueprint found in nature - including the human jaw (right) When this triangle is used to construct the drawing it produces a specific ratio between the size of the square and the circle. Dr Sweeney has discovered that this ratio – 1.64 – is almost identical to a 'special blueprint number' – 1.6333 – that appears over and over again in nature for building the strongest, most efficient structures. This same number is found in the geometry of a perfectly functioning human jaw, the unique proportions of the human skull, the atomic structure of super-strong crystals and the tightest way to pack spheres. 'We've all been looking for a complicated answer, but the key was in Leonardo's own words,' Dr Sweeney, who graduated from the School of Dental Science at Trinity College in Dublin, said. 'He was pointing to this triangle all along. What's truly amazing is that this one drawing encapsulates a universal rule of design. 'It shows that the same "blueprint" nature uses for efficient design is at work in the ideal human body. 'Leonardo knew, or sensed, that our bodies are built with the same mathematical elegance as the universe around us.' According to the dentist, the discovery is significant because it shows that Vitruvian Man is far more than just a beautiful piece of art. Leonardo da Vinci is also known for his magnificent artworks such as the Mona Lisa, which hangs at the Louvre Museum in Paris (pictured) Who was Leonardo da Vinci? Leonardo di ser Piero da Vinci, more commonly Leonardo da Vinci, is one of the greatest minds of the last millennium. The polymath was a driving force behind the Renaissance and dabbled in invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. He has been attributed with the development of the parachute, helicopter and tank. He was born in Italy in 1452 and died at the age of 67 in France. After being born out of wedlock, the visionary worked in Milan, Rome, Bologna and Venice. His most recognisable works include the Mona Lisa, the Last Supper, Vitruvian Man. Another piece of artwork, dubbed the Salvator Mund, sold for a world record $450.3 million (£343 million) at a Christie's auction in New York in 2017. Instead, it is the work of 'scientific genius that was centuries ahead of its time', he said. The pen-and-ink drawing of the nude male in two different poses, with arms and legs enclosed within a circle and square, was created by the Renaissance polymath around 1490. It was partly influenced by the writings of Roman architect Marcus Vitruvius Pollio, who believed the human body has harmonious proportions. He proposed that a human figure could fit perfectly inside a circle and a square but provided no mathematical framework for achieving this geometric relationship. Da Vinci, who solved the puzzle, never explicitly explained how. For the last 500 years scientists have come up with numerous theories and ideas but none have matched the actual measurements. The study, published in the Journal of Mathematics and the Arts, reads: 'For over 500 years, Leonardo da Vinci's geometric system for establishing the precise relationship between the circle and square in his Vitruvian Man drawing has remained a mystery. 'This paper demonstrates that Leonardo's explicit textual reference to 'an equilateral triangle' between the figure's legs provides his construction method and reveals the anatomical foundation for his proportional choices. 'The analysis shows that Leonardo's equilateral triangle corresponds to Bonwill's triangle in dental anatomy—the foundational geometric relationship governing optimal human jaw function.' It concludes: 'The findings position Vitruvian Man as both artistic masterpiece and prescient scientific hypothesis about the mathematical relationships governing ideal human proportional design.' Scientists have previously compared the Vitruvian Man with nearly 64,000 physically fit men and women and discovered da Vinci was to anatomical measurements of the modern-day human. The team found the groin height, shoulder width and thigh length of today's measurements were 10 percent within those of the Vitruvian Man. However, the head height, arm span, chest and knee height are slightly more than da Vinci's estimates. THE MANY ACCOMPLISHMENTS OF LEONARDO DA VINCI Leonardo da Vinci is best known for his stunning artwork but the Italian Renaissance painter had many talents. He was also a sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer. The Mona Lisa is his most famous and most parodied portrait while his painting of The Last Supper is the most reproduced religious painting of all time. Leonardo's drawing of the Vitruvian Man is also regarded as a cultural icon - being reproduced on items as varied as the euro coin, textbooks, and T-shirts. Only around fifteen of his paintings survive because of his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination. Leonardo is also revered for his technological ingenuity. He conceptualised a helicopter, a tank, concentrated solar power, a calculator, and the double hull, also outlining a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime, but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded. He made important discoveries in anatomy, civil engineering, optics, and hydrodynamics, but he did not publish his findings and they had no direct influence on later science.
