Technology Leonardo da Vinci's bridge design is tested by MIT engineers
A hidden da Vinci lurks beneath 'The Virgin of the Rocks'
Researchers at the National Gallery of London have used cutting-edge techniques to reveal a hidden drawing beneath Leonardo da Vinci's The Virgin of the Rocks. It shows that the great artist and his assistants, after laying out the original design, elected to take the biblical-themed painting in a completely different direction, to say the least. First, know that there are two versions of The Virgin of the Rocks, one hanging in the Louvre and one in the National Gallery of London. It's thought that da Vinci first created the Louvre version by himself for a commission, but then sold it privately.
In 1502, Leonardo da Vinci sketched out a design for what would have been the world's longest bridge at the time -- 280 meters (918.6 feet). Although the bridge itself was never built, engineers at the Massachusetts Institute of Technology have tested the design to see if it would work.
The results of their work wereat the International Association for Shell and Spatial Structures conference in Barcelona, Spain, according to a release by the university.
Venice court temporarily blocks da Vinci loan to Louvre

Da Vinci submitted his innovative bridge sketch when Sultan Bayezid II, ruler of the Ottoman Empire from 1481 to 1512, put out a request for bridge designs that could span across the Golden Horn. This natural river estuary separated the cities of Galata and Istanbul.
Da Vinci's proposal was not selected. Now, a cable-stayed bridge is in place. But what would it have been like if da Vinci's design had been constructed?
MIT engineers studied his drawing, as well as the materials he would have had available, and construction conditions at the time. They built a scale model to test its stability and how it might react to different conditions.
At the time of his concept, the bridge would have been a novel design compared to popular semicircular arches. These arches needed piers placed along the bridge's span to support its length. But da Vinci proposed a flattened arch, still reaching a height so that ships could pass beneath it, but using one gigantic arch to help people cross from Istanbul to Galata.
NTSB To Hold Meeting On Cause Of FIU Bridge Collapse

NTSB says the Florida Department of Transportation listed the company Louis Berger Group, Inc. on a website-generated report as prequalified to evaluate the construction of a complex concrete bridge.
"It's incredibly ambitious," said Karly Bast, a recent MIT graduate student. "It was about 10 times longer than typical bridges of that time."
"But it was also quite sophisticated geometrically, with much more curvature and three-dimensionality than typical arch bridges," said John Ochsendorf, MIT professor of architecture and civil and environmental engineering.
In order to stabilize the bridge against lateral sway and earthquakes, da Vinci wanted the bridge's supportive abutments on either end of the arch to spread outward. He knew the area might experience earthquakes, as it had in the past.
At the time, stone would have been the primary material used to build a bridge of such length because wood or brick would not have been practical. The researchers didn't find any details by da Vinci for the construction of the bridge, but believe the stones would have been fitted together without mortar.
Da Vinci bridge design holds up even after 500 years, MIT proves
3D printing lets MIT engineers put the Renaissance man's plans to the test.Recent graduate student Karly Bast shows off the scale model of a bridge designed by Leonardo da Vinci that she and her co-workers used to prove the design's feasibility.
Their model included 126 3D-printed blocks fitted together for a 32-inch long bridge. When a bridge was constructed in this Roman style, scaffolding was used to keep the stones in place. Once the final keystone was in place, the scaffolding could be removed. The researchers did the same thing with their model.
"When we put it in, we had to squeeze it in," Bast said. "That was the critical moment when we first put the bridge together. I had a lot of doubts. When I put the keystone in, I thought, 'This is going to work.' And after that, we took the scaffolding out, and it stood up. It's the power of geometry. This is a strong concept. It was well thought out."
Previous attempts to create the bridge -- such as a pedestrian bridge in Norway -- used modern materials.
Ochsendorf said if the bridge were constructed today, it would likely be made with steel or concrete. But the researchers wanted to know if da Vinci's design would have been viable at the time of its creation.
The engineers also tested the bridge's stability by simulating what might have happened if the soil was weakened by earthquakes. The bridge withstood the simulations.
Remembering Rep. Elijah Cummings, Atatiana Jefferson: 5 things to know Thursday
Rep. Elijah Cummings to lie in state and Dallas pays final respects to Atatiana Jefferson. Here are 5 things to start your Thursday.The funeral for the woman killed at her home by a police officer in Fort Worth, Texas, is scheduled for Thursday after a family dispute that had delayed the services was settled earlier this week. The service for Atatiana Jefferson is planned for 11 a.m. at Concord Church in Dallas. Jefferson, 28, was killed in the early morning of Oct. 12 when a Fort Worth police officer shot her through the window of her house, where she was playing video games with her 8-year-old nephew.
Could the bridge be used today? Bast said lighter, stronger designs for bridges, based on available materials, would win out. But it highlights the brilliance of da Vinci's design.
"What we can learn from Leonardo da Vinci's design is that the form of a structure is very important for its stability," Bast said. "Not only is Leonardo's design structurally stable, but the structure is the architecture. It is important to understand this design because it is an example of how engineering and art are not independent from each other."
Ochsendorf said the team wanted to know if da Vinci's idea "could actually have stood up."
"It would not have been easy to build, in the 16th century or today, but we have now proven that his ideas on bridge design were well ahead of his time," he said. "It is unlikely that it will ever be built for reasons of cost and practicality, but it could inspire future designers to dream big."
Leonardo da Vinci probably had ADHD
The famouspainter probably had an attention deficit disorder.
This is the view of psychiatry professor Marco Catani, who believes that attention deficit and hyperactivity disorder - known as ADHD - explain both Da Vinci's chronic hesitation and his creative drive in art and science.

"Leonardo was very modern and very similar to today's people who are struggling with this modernity, which are connected to technology, the Internet, we are bombarded with news and We need to be able to focus our attention on something, "says Catani.
London's Queen's Gallery is currently hosting an exhibition of more than 200 da Vinci drawings. It is considered the largest exhibition of works by the artist for 65 years.
