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.

In spring 1665 a college student named Isaac Newton studied natural philosophy, what we call “science.” Back then, a good student could learn everything to know about the natural world. But plague, the Black Death, came to England. Cambridge University closed. Isaac went home to Woolsthorpe.
For two years Isaac thought about his studies during four years at university. He’d always been thoughtful—not the best at games, making friends, or minding sheep. But everybody knew Isaac Newton liked to think. Folks told time by the sundial he’d drawn on a wall.
Home at Woolsthorpe, Isaac’s learning about science and math bubbled up in his head like yeast rising in a loaf of bread.
So... Newton unplugged. His mind roamed like that of an artist or composer. He was driven by the need to create—not paintings or symphonies, but questions.
“Why do things always fall down?”
“Why does the earth move around the sun?
“Why doesn’t the moon fall onto the earth?”
“Does everything ‘up there” work like things work ‘down here?’”
Isaac Newton answered his questions with three science rules, Newton’s Laws of Motion.
At Woolsthorpe, Newton grappled with the concept of moving objects. He worked out the math to find the area under curves. He called this math fluxions. Today we call this calculus, useful for launching rockets or tracking TV signals.
Once back at Cambridge, Newton said nothing until he read someone else’s paper on fluxions. Newton published a better paper. Soon he was Cambridge’s top math professor.
Isaac Newton wondered another twenty years. He played with prisms in a dark room and theorized that white light comprises the visible spectrum of red, orange, yellow, green, blue, indigo, and violet. He practiced alchemy and chemistry, looking for the legendary philosopher’s stone to turn base metals to gold. In 1687, Newton published our most important science book, the Principia.
In the Principia, Newton showed how laws of gravity and motion work the same at great distances—far off in space, or in your classroom. We accept these ideas, but in 1687 many still had medieval beliefs that sun, moon, planets, and stars all traveled in their own crystal spheres.
Yes, Newton wondered about A LOT:

The amazing, engaging, math exponent
Imagine Earth as a button. I don’t mean you’re going to sew it onto your shirt. But imagine the planet Earth shrunk to the size of a button. (Of course Earth is not flat like a button but we’re giving our shrunken Earth the same diameter as a shirt button.)
Go ahead and draw a circle around a shirt button. Call it “Earth.” Suppose you wanted to draw Jupiter, the largest planet, at the same scale as this micro-Earth. That means you’re going to shrink it to the same fraction of its original size as our button-Earth. What size would little Jupiter be?
One way to find out would be to calculate how many times bigger the real Jupiter is than the real Earth. Earth’s diameter is about 8,000 miles (13,000 kilometers). Jupiter’s is about 88,000 miles (143,000 km). Divide the size of Jupiter by the size of Earth to see that Jupiter is about 11 times bigger.
So, since Jupiter’s diameter is 11 times that of Earth’s, put 11 buttons in a line to show the diameter of Jupiter. Then draw the circle that represents Jupiter. If you don’t have 11 buttons, just look at the picture. Did you think the Earth was a big place? Look at it compared with Jupiter!
But what about the sun? The sun’s diameter is about 865,000 miles (1,400,000 km). That means it’s almost 10 times bigger than Jupiter. Can you find a way to draw a circle 10 times the size of our Jupiter? We’ve drawn part of it for you, on the same scale as our button-sized Earth. On the picture, it’s labeled “our arc.” (An arc is part of a circle.) Looking at the arc, you can imagine the rest of the circle and compare the sun to Jupiter and Earth. A minute ago, you thought Jupiter was big. Now it looks shrimpy compared to the sun!
But is the sun really gigantic? Do some research to find out the size of a red giant star like the strangely named Betelguese (pronounced “beetle-juice.”) Figure out what it looks like compared to our sun, which is a medium-sized star. You may be amazed at the difference. And you thought the sun was big!
Is anything truly big? Is anything truly small? Or does that depend on what it’s being compared to?

Henry Ford is famous for founding the Ford Motor Company in 1903. He built the Model T and changed America from a horse-and-buggy country to a nation of paved roads and honking cars. Yet most people don’t realize that Henry also transformed American agriculture with his work with soybeans.
During the Great Depression of the 1930s many farmers lost their farms or left crops to rot because they cost too much to harvest. Henry thought this was a waste, so he began to look for ways that common crops could be used in industry. He built a laboratory at Greenfield Village, and studied the chemical makeup of every fruit, grain and vegetable. After two years, Henry found the: the soybean! It was the perfect crop to use in his factories because it was packed with oil and protein.
The oil made a paint that was glossier, less expensive, and dried to a harder finish than other coatings. By 1934, every new Ford boasted a coat of soybean paint. The soy protein, mixed with a chemical resin, created a sturdy plastic. Soon cars had soybean plastic gearshift knobs, light switches and horn buttons. Ford claimed that every car contained a bushel of soybeans.
But Henry wanted a car that was all soybeans. To do this he had to make large plastic panels, which took longer to perfect. The first panels cracked. But eventually Henry had a plastic trunk lid attached to his car so he could show people how sturdy it was. He even hit it with an ax and didn’t make a dent.
Henry affixed fourteen plastic panels to a steel frame, and showed off his new car on August 13, 1941. Unfortunately the car was never manufactured. Four months later America entered World War II. The soybean plastic car rolled into storage, its steel frame recycled in the war effort. Henry died shortly after the war, and no one continued his work on the plastic car.
But his soybean research did spark a movement to use soy in manufacturing, which made soybeans the second largest crop grown in America. Furniture, flooring, candy, crayons, and all kinds of food contain soy. And even though we don’t drive soybean plastic cars yet, there are still plenty of beans in every Ford. All their seats are stuffed with soybean plastic foam.

Henry Ford (July 30, 1863 – April 7, 1947) was an American captain of industry and a business magnate, the founder of the Ford Motor Company, and the sponsor of the development of the assembly line technique of mass production.

The world's first car made of what was called agricultral plastic is shown in February 1942. The plastic was a strong material combining soy beans, wheat and corn. Although the car never caught on, it was lighter and therefore more fuel efficient than the standard metal body. Wikimedia Commons
Despite the practical benefits of a car made out of food products (fuel efficiency and the conservation of steel that was scarce during World War II), the idea was the source of a lot of good-natured humor. From the Collections of The Henry Ford

Teaching the Power of Wonder
When I was a kid fifty years ago, President Theodore Roosevelt had a bad rap. We learned that way back in the 1900s, he banned Christmas trees from the White House. What a lousy father, I thought.
Down through the years, the story went something like this: Across America in the early 1900s, huge forests were in danger of destruction from a lumbering practice called “clear-cutting.” Lots of newspapers and public leaders asked Americans to stop going to the woods to cut Christmas trees. Now when the Roosevelts and their six kids lived in the White House, they didn’t have a tree. Stockings and presents, but not a tree. So folks assumed that Roosevelt had outlawed Christmas trees, because he was a huge outdoorsman and conservationist.
But, according to people who’ve done their history homework, that’s not the whole truth. It’s possible that First Lady Edith Roosevelt had six kids to think of and didn’t want the extra fuss of a Christmas tree. Christmas trees had become very popular ever since the old German tradition was picked up in the United States, but not everyone chose to have one.
As it turned out, the Roosevelts did have at least one tree, courtesy of their eight-year-old son Archie. On Christmas morning 1902, Archie surprised his family. The president wrote about it in a letter that told of Christmas morning:
A magazine ran the story of Archie’s tree the next year. From then on, it picked up all sorts of embellishments, sort of like playing telephone at a birthday party.
Today, the best explanation of the old story appears on a blog run by the Forest History Society. Visit their website.
And for more cool facts about Christmas trees, check out the website of the folks who know, the College of Agriculture at the University of Illinois.
Theodore Roosevelt for Kids brings to life this fascinating man, an American giant whose flaws were there for all the world to see. Twenty-one hands-on activities offer a useful glimpse at Roosevelt’s work and times. Readers will create a Native American toy, explore the effects of erosion, go on a modern big game hunt with a camera, and make felted teddy bears. The text includes a time line, online resources, and reading list for further study. And through it all, readers will appreciate how one man lived a “Bully!” life and made the word his very own.
