This Is the Surprising Reason Why Airports Are Carpeted

  This Is the Surprising Reason Why Airports Are Carpeted This Is the Surprising Reason Why Airports Are CarpetedWhile common sense might call for terminals to be designed with tile floors — both for the benefit of passengers wheeling luggage and to make it easier for the staff to clean — most airports are carpeted, instead. Why? Turns out, those carpets have been strategically chosen to influence your mood and behavior.

Have You Ever Wondered Is the leaning Tower of Pisa falling ? This made the foundation stronger over time and is the main reason the tower never fell over.

The Reason the Leaning Tower of Pisa Leans Is the Same Reason It ’ s Never Fallen . For more than 20 years, researchers have been trying to figure out what makes the Leaning of Tower of Pisa such a unique landmark.

For more than 20 years, researchers have been trying to figure out what makes the Leaning of Tower of Pisa such a unique landmark. And, in a twist that seems like a moral from Aesop’s fables, engineers and soil scientists have concluded that the very reason the tower leans is the same reason it has never collapsed.

In 1173, construction began on the Pisa cathedral’s new bell tower. By the second year of construction, it was already starting to tilt. It took almost 200 years to complete, with engineers and architects constantly trying — and failing — to stop the lean.

Why Does the Leaning Tower of Pisa Lean?

  Why Does the Leaning Tower of Pisa Lean? Soft soil is only the beginning of the story.The next year, construction on the tower began and almost immediately there were problems. The tower site sat on soft ground composed mostly of clay, fine sand, and shells (the city sits between the Arno and the Serchio rivers). By the time the builders finished the second floor in 1178, the tower was beginning to lean.

Engineers and scientists have been fascinated by the unusual structure for half a millennium. Earthquakes, Mussolini, two hundred years of construction misadventures— the Leaning Tower of Pisa has kept standing through it all.

Upon completion in 1370, the tower was leaning at about two degrees. In the 20th century, it was estimated that the tower was shifting about 0.05 inches per year. By 1990, the tower was tilted at a 5.5-degree angle (about 15 feet). Between 1999 and 2001, work was done on the tower to reduce its tilt by 0.5 degrees.

But despite all of this precarious leaning and correction, the tower has never fallen — despite being impacted by at least four very strong earthquakes.

The new study, led by a professor from Roma Tre University, has attributed this to something called dynamic soil-structure interaction.

Basically, because the tower is so rigid and high (191 feet) and the ground beneath it so soft, every time an earthquake hits, the “vibrational characteristics of the structure” are changed to make it so “the tower does not resonate with earthquake ground motion.”

The Eiffel Tower Could Be Repainted Its Original Vibrant Color

  The Eiffel Tower Could Be Repainted Its Original Vibrant Color Many Parisians hated the Eiffel Tower when it was first erected in 1889. In its 129 year history, the Eiffel Tower has had 19 different paint jobs. And when the monument undergoes its 20th painting later this year, the Ministry of Culture and the City of Paris will decide if its current subdued metal color will remain — or if something else will take its place.

The so-called Leaning Tower of Pisa is one of the most famous buildings in the world, although maybe not for the reasons its original architects would have wanted. In 1173, construction began on a white marble bell tower for the cathedral complex in Pisa

The Leaning Tower of Pisa is just another lesson why we should all embrace flaws. It may wobble, but it never falls down.

'And much of the time, the stains are basically just dabbed with cleaner until they can’t be seen anymore.” She recommends laying a towel or sheet down before taking a seat.
