Several years ago, I rode the world’s fastest elevator to the top of one of the world’s tallest buildings—Taipei 101. Shaped like an elegant stalk of bamboo, Taipei 101 soars 1670 feet above the island nation of Taiwan. However, the engineers who designed the building faced two monumental challenges. The first is that dozens of earthquakes shake Taiwan each year. The second is that in an average year, Taiwan gets hammered by three or four hurricanes, or typhoons.
How, engineers wondered, could they keep people comfortable inside Taipei 101 when it swayed back and forth? More important, how could they keep the building from getting damaged or collapsing in a massive earthquake or 100 mile-per-hour winds?
One solution: a damper ball.
Damping devices are weighty objects that can reduce the motion of a bridge, building, or other structure. In the case of Taipei 101, engineers placed the damper ball near the top of the building—the part that sways the most. The ball is hung from thick cables inside the building and rests on giant springs or “dampers.”
One of Isaac Newton’s basic laws of physics is that an object at rest tends to stay at rest—and the damper ball proves it. Every time Taipei 101 starts swaying, the damper ball wants to stay where it is and “pulls back” on the building, reducing how far the building moves. When the building sways in the opposite direction, the process repeats itself—but in the reverse direction. Of course the building also pulls on the damper ball, but the ball’s movements are restricted by the dampers it presses against.
Does the system work? You bet. The damper ball inside of Taipei 101 reduces the building’s movement by 30 to 40 percent!
Of course not just any damping device could protect an enormous building like Taipei 101. Taipei’s damper ball weighs 1.5 million pounds—as much as two fully-loaded jumbo jets. It is composed of 41 circular steel plates that stand taller than a one-story house. In 2008, when a giant earthquake hit mainland China, the people of Taiwan could feel it hundreds of miles away. The damper ball did its job, resisting Taipei 101’s movement, keeping the building safe. During Typhoon Soudelor in 2015, the damper again worked like a charm, protecting the building against 100- to 145-mile-per-hour winds.
Besides protecting Taipei 101, the damper ball has become a major tourist attraction. Each year, thousands of visitors ride to the 89th floor. They take selfies next to the damper ball. They even take “Damper Baby” souvenirs home with them. If you’re ever lucky enough to visit Taiwan, check it out!
The damper ball is visible between the 89th and 91st floor of Taipei 101 and has become an attraction for tourists.

Celebrating the History of Science
and the Science behind History
During the Renaissance, French kings and queens built many palaces, in an area known as the Loire Valley. The royal family would travel from palace to palace to get away from Paris, the way you might head to a lake house. The Loire Valley is not very close to Paris. It’s about 110 miles from Paris to the palace of Chambord, for instance. I wondered how long it took sixteenth century travelers to make this journey—and why there were so many palaces.
First, the distance. Under the best of conditions (good roads, decent weather, level ground), humans can walk four miles per hour over long distances. Horses can’t do much better–maybe five mph—but a lot less if they’re pulling something or if roads are in awful condition. A horse can canter at 20 mph, but it can only do that for six to eight miles at a time, after which it will slow down and walk, or stop completely. So it would have taken a long time to get from place to place. Under the best conditions, a journey from Paris to Chambord would have taken three weeks.
But in fact, it took a lot longer than that. Because in the sixteenth century, the royal court didn’t just hop on a horse and head to their country home. They took everything and everyone with them, loading all the stuff onto the backs of horses and mules.
When Catherine de Medici was queen of France, she traveled with her ladies and gentlemen, foreign ambassadors, pet bears, servants, retainers, attendants, apothecaries, astrologists, tutors, musicians, cooking pots, food, clothing, portable triumphal arches, wall hangings, and furniture.
And the reason there were so many palaces is simply that the court in Renaissance times –thousands of people–had to move around from estate to estate so as to find new hunting grounds. Once they’d exhausted the food supply in the area, they moved on to the next estate. Also, the sanitation was dreadful. After thousands of people had taken up residence in and around a great estate for a few weeks, filth piled up, and with it, stench and disease.
The royal procession could be miles long. When Catherine de Medici’s court packed up and left for a new palace, the beginning of the royal caravan sometimes entered a town before those traveling at the back of it had left the last one.

Who would build the world’s tallest building – the powerful Bank of Manhattan Trust Company down on Wall Street or Walter P. Chrysler, the automobile tycoon up on 42nd Street? It was early 1929, and a race for the sky raged in New York City. In late summer, the newspapers reported that the bank soared to 973 feet, just two feet higher than planned for the Chrysler Building. To the king of cars this was intolerable, so he turned to his architect, William Van Alen, who decided to outfox the competition.
Five months later, people in New York were treated to an extraordinary sight. In 90 minutes, a splendid tower, topped by a silvery spire, with triangular windows, emerged from the building’s open roof. Secretly assembled in the fire shaft, it rose to a height of 1,046 feet, making the Chrysler Building the world’s tallest building.
Van Alen had given Chrysler a structure that not only scraped the sky, he also, most imaginatively, used details of cars as decorations. Near the top of the building perched eight eagle-headed gargoyles, based on the hood ornament of a 1929 Chrysler Plymouth. Thirty-six stories above the street, there’s a wrap-around frieze of stylized cars featuring real metal hubcaps and four giant radiator caps.
For a few months, until the Empire State Building took over as the world’s tallest building, Chrysler relished his number one status. His lavish apartment was near the top, and he boasted to friends and foes alike that he had the highest toilet in the city. So there he sat, on his porcelain throne, delighting in his elevated position.
Chrysler and Van Alen expected rave reviews when the building was completed, but that didn’t happen. “The height of commercial swank,” sneered The New York Times. “Stunt design, with no serious significance,” sniffed The New Yorker, and another newspaper accused the spire of having the “appearance of an uplifted swordfish.”
But things change. Now some 75 years later, the Chrysler Building is many people’s favorite skyscraper, and recognized as an outstanding example of Art Deco, the style of the twenties and thirties. Above all, there’s that incomparable swordfish-nose spire.
It was Van Alen’s aim to have the triangular windows lit up at night. And now, long after his death, they do, launching the Chrysler Building into the Manhattan sky with all the fantasy and glitter of the Jazz Age.

St. Paul's Cathedral during the blitz of World War II.
When I interview people in my work as a writer, I soak up the stories they share about their lives. This is what brings history alive. I’ve always wished for a way to interview historic buildings, because they could tell stories from such a different perspective, having seen it all and heard it all. My dream interview would be St. Paul’s Cathedral in London, a place rich with history—and therefore, with stories.
I have learned that those with the most to say can be wary of interviewers. Sometimes employing a little charm can help them warm up. So I would begin by complimenting St. Paul’s on how wonderful it looks for a building that opened in 1708. I would reference its great architect, Christopher Wren, who was also an astronomer and mathematician, as is evidenced in many of its design elements. I’d mention its magnificent dome and its massive booming bells that can be heard for miles.
“You’re the prize jewel in a city rich in architectural beauty,” I’d say. “No wonder so many notables have been baptized, married, and had their funerals here.”
Flattered but still reserved, St. Paul’s might ask me what I like best about it. “I have two favorites,” I would reply earnestly, mentioning first the Crypt, where many of England’s war heroes are buried, along with famous painters and poets. (Writers and composers are at nearby Westminster Abbey). Other notables, like Florence Nightingale and Lawrence of Arabia, are here, too. It’s altogether quite a congenial place.
Starting to thaw a bit, St. Paul’s might wonder aloud about my second favorite, and I would single out the American Memorial Chapel, located behind the High Altar and dedicated to the memory of the 28,000 Americans who died defending England in World War II.
“And speaking of that war,” I would tell St. Paul’s, “I am awed by Londoners’ resolve that you, their national treasure, would not be destroyed during the Blitz when so much of the city burned. Volunteer firefighters, both men and women, were stationed at all times on your roof. When bombs exploded, starting fires, they were right there to put them out, a number of them sacrificing their lives.”
St. Paul’s would nod, remembering.
“The British love you very much,” I would say.
St. Paul’s would pause, clear its throat, and then reply, “Let me tell you some of my stories.”

“What is this country bumpkin up to? Is this some kind of a joke?” Laughter rippled through the conference room in Richmond as Lemuel Chenoweth unloaded his saddlebags and took out a bunch of oak sticks wrapped in newspapers.
He was the last builder to show his plans for the great competition in 1850 to build a bridge across the Tygart River in western Virginia (now West Virginia). Only a ferry connected the bustling north-south throughway at Philippi, causing traffic jams and the slowing of our young nation’s relentless commerce and travel.
Engineers had come from all over the east to show their plans … blueprints of cable suspension bridges, fancy cantilevered structures, an arched bridge. It had to be durable, and support wagonloads of heavy goods and herds of livestock. ridge across the Tygart River in western Virginia (now West Virginia). Only a ferry connected the bustling north-south throughway at Philippi, causing traffic jams and the slowing of our young nation’s relentless commerce and travel.
Quietly Lemuel assembled a miniature bridge, using no hammer or nails. Compared to the fancy bridge models shown, his was plain. Then, he pulled out two chairs, placed his construction across them, and spoke.
“Since I have no blueprints,” he said, “you may allow me a demonstration.”
Suddenly he stepped up onto the top of the model, and walked across it--from one end to the other. A gasp went up. No way could it hold! They knew their mathematics. Had this been the actual bridge it would have been as if a six-hundred-foot man stood on it. But the model held, and in the hushed silence that followed, Lemuel turned to the other contestants and asked, “Can you stand on your models?”
No one dared. They all knew theirs would be crushed.
And that's how Lemuel Chenoweth, a shy western Virginian with a third-grade education, won the competition for the famous Tygart River Bridge.
The double-barreled bridge has survived fires, the Civil War, floods, and 18-wheeler trucks. It is the only covered bridge left in the US serving a federal highway. It has its own museum, and in 1983 Governor Jay Rockefeller declared June 15 Lemuel Chenoweth Day.
Lemuel started out making furniture, wagons, and coffins, and later built houses, a church, and many bridges. He married Nancy Hart, the great-granddaughter of John Hart, signer of the Declaration of Independence. They had 13 children.
So how do we know about this story?
Because Lemuel Chenoweth was my great-great- granddaddy, and throughout my childhood I heard the story of Lemuel, the model bridge, and the two chairs.
