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.

The Tower of Pisa has been leaning for more than 800 years, but it has 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.

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 Tower of Pisa has been leaning for more than 800 years, but it has never fallen .

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.”

Why Do We Eat Ham on Easter?

  Why Do We Eat Ham on Easter? Certain holidays go hand-in-hand with certain foods — like turkey on Thanksgiving, for example. Ham on Easter is another one. But is there any real reason why we tend to eat ham on Easter, aside from tradition?The reason ham is traditionally eaten at Easter is actually because it’s in season! Historically, pigs were usually slaughtered in the fall, when it’s chilly outside and the cold could keep the meat fresh during the several days it would take to break down and prepare the hog.

The Leaning Tower of Pisa ' s unique architectural mystery has lured tourists to visit its location in Italy for years. However, researchers have discovered why this popular attraction never falls over after surviving countless earthquakes.

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