Flat Paper Flight

Since he was a boy, John Collins has been fascinated by paper airplanes. Who isn’t? Most of us have folded the familiar dart-shaped classroom airplane. Good fun. And it’s science.

Big and small aircraft depend on the same four principles: weight (of the craft), drag (wind resistance over the craft), lift (upward force from air passing over the craft’s flight surfaces), and thrust (what pushes the craft). A 747 Jumbo Jet and a paper airplane depend on the same forces.

     Collins wanted to fold this aeroscience into paper. But how to build (fold) complex principles into something so small?

     He found the ancient Japanese art of origami and used its sculptural tricks. He created paper aircraft that do astonishing things. One comes back in a horizontal circle, like a boomerang. Another flies up, turns over and comes back vertically. One actually flaps its wings as it glides slowly. To John, they’re all working science experiments: every flight leads to some knowledge and to new ideas for tweaking the aircraft so it flies better.

     John Collins became “The Paper Airplane Guy.”  He believes that scientific research happens everywhere, every day. He says, “It doesn’t take computers, lab coats, microscopes and the like. It takes a hunger to know. Science is just the structured way we find stuff out. The science you can do with a simple sheet of paper is no less important than what can be done with an electron microscope.”

     On February 26, 2012, John and Joe Ayoob stood in a big, windless aircraft hangar with John’s best-so-far flyer, Suzanne. (He named it after his wife.) Joe was a professional football quarterback who learned to throw Suzanne hard but steady, not like a football but like a delicate piece of origami. Joe threw Suzanne up, up, and it dived down to fly – really fly – 226 feet and 10 inches, the Guinness World Record for distance thrown.

     John wanted paper airplanes to welcome young people into science. He started a National Paper Airplane Contest called the Kickstarter Project with a big prize for anyone who throws Suzanne farther than Joe. Or you could throw your own better, more aeronautically elegant paper airplane. It was a simple, scientific task. Every paper airplane and every flight would be a new experiment, just as important as the Wright Brothers’ Kittyhawk flight. Science isn’t just geeks and labs; we’re all part of it. The project didn’t get support and ended. John would like to direct people to  www.TheNationalPaperAirplaneContest.com. Air and Science museums across the country will be hosting events. The museums get three Fly for Fun Days; STEM education days that teach basic flight concepts and skills for the national contest.

America's Rarest Pine Tree

Dorothy Hinshaw Patent
Nature’s Animal Ambassador

When we think of endangered species, we are likely to think “cheetah” or “grizzly bear” or some other big, familiar, and in-the-news animal. But unfortunately, just about any sort of living thing can enter the list of endangered life. Scientists fear that the continuing elimination of habitat by humans and the changing climate could result in the loss of a million or more species in the foreseeable future.

The Torrey pine, native to the coast of southern California, is on the endangered list. Before the city of San Diego and its suburbs developed, woodlands featuring this species thrived along the nearby rocky coast. The frequent cool afternoon fog helped the trees tolerate a climate where rain is scarce during the summer months.

Now, largely because of human development, this beautiful tree with open, spreading branches is critically endangered. There are just two areas left where these trees grow in the wild. Fewer than 5,000 individual trees live on tiny Santa Rosa Island off the Santa Barbara coast and in the Torrey Pines State Reserve on the San Diego coastline.

In addition to having an ever-shrinking natural habitat, the Torrey Pines have recently struggled to survive an onslaught of the five-spined engraver beetle, which bores through the bark and lays its eggs in the cambium layer of the tree. The beetle attack can result in shutting off the supply of water and nutrients to the tree, killing it. Healthy trees may be able to survive, but drought can weaken a tree, making it vulnerable to attack.

Torrey pines do not replenish themselves easily. They take their time to produce seeds. The male flowers develop in February as clusters of reddish finger-like structures on lower branches. Their pollen fertilizes the female blossoms, which look like tiny red cones. It takes about 3 ½ years for the cones to grow and the seeds to develop fully. Then the cones release seeds, but some may remain until the cone itself drops from the tree as long as ten years after pollination.

The Torrey Pines State Reserve works hard to protect these rare trees, but it may be too late. The increasing heat and dryness brought about by climate change could weaken the remaining wild trees, resulting in beetle damage and early death. Let’s hope these hardy beauties find a way to survive these difficult challenges.

In The Call of the Osprey, Dorothy Hinshaw Patent's engrossing narrative nonfiction and William Muñoz's dramatic photos offer a stunning exploration of the mercury pollution in Montana that causes harm to humans and ospreys alike.
"Patent's lucid prose and Muñoz's clear color photos work together to document the efforts of the Montana Osprey Project... An exciting addition to a stellar series."

“Wrong-Way" Corrigan

“Where am I?”

The smiling young pilot was apparently nonplussed. He had landed at Dublin’s airport without a permit – or even a passport – and was now confronting several frowning custom officers.

“I took off from New York with the intention of flying to Los Angeles,” he explained. “After twenty-six hours coming down through the clouds I was puzzled to see water instead of land. I must have misread my compass and followed the wrong end of the needle.”
The Irish, never averse to a good yarn, looked at his primitive plane and cheered him for his audacity. When word of his remarkable flight reached the United States, the pilot, Douglas Corrigan, became known as “Wrong Way” Corrigan.

The story of Corrigan, an Irish-American mechanic, has been called an Irish fairy tale, an impish yarn spun with a straight face. It unfolded in 1938 but really began when Corrigan, at age twenty, worked on the team that built The Spirit of Saint Louis, the plane that took Charles Lindberg across the Atlantic. Lindberg became Corrigan’s hero. His dream: to make that same flight himself.

But Corrigan was just an ordinary guy struggling to make ends meet. Still, he managed to get a pilot’s license, and began flying in his spare time. In 1931 he bought his own plane. It was a battered old machine, but Corrigan loved it, and radically changed it, so that, one day, he would be able to duplicate his hero’s transatlantic flight. He was set to go – except for one major obstacle: more stringent regulations for trips overseas.

Applying for a government permit, he was turned down because his plane was too old. Then, in 1938, he got a license for flights between Los Angeles and New York. Seeing him him take off for Los Angeles, people wondered why he headed northeast instead of west.
The world laughed - an unlikely hero, a mirthful, courageous individual who thumbed his nose at authority.

Back in New York, Corrigan was treated to a ticker-tape parade on Broadway. A nationwide tour followed. He met with President Roosevelt, received membership in the Liar’s Club in Wisconsin, was hailed as “Chief Wrong Way” by a Native American tribe, showered with compasses, and given a watch that ran backward.

Asked about his flight, his response was always the same: a grin and “Man, I didn’t mean to do this at all.”

The Battle Hymn of the Chicken Pox Troopers

How does a virus cause a disease? A virus is not a complete living thing. It is like a free-floating nucleus of cell. It doesn’t “grow” but under certain conditions it can make a copy of itself or reproduce. It invades the cells of other living things to use the internal structure of the host cells to reproduce. At a certain point, the number of new viruses in a cell is so large that the cell ruptures and dies, spilling out newly made viruses to continue the invasion to other uninfected cells.

One virus we understand very well is chicken pox. Chicken pox is a very contagious disease that enters the body through the air and affects mostly children. When I was young almost every kid got chicken pox but, since 1995, there has been a vaccine, which makes you immune and protects the spread of the disease to others. Is there another way to explain how this virus works? Suppose I imagine a virus could think, which it can’t. But, imagination gives me the freedom to think differently.

So I wrote a poem about an army of chicken pox viruses as they are about to attack a human being, maybe you, my reader. A “battle hymm” is a chant or a song to rally the troups just before an attack.

The Battle Hymn of the Chicken Pox Troopers

Charge forward, fellow viruses!
Invade a cell or two
Then let us join together
And make a chicken pox on you.

Let cells try to fight us
No matter what they do
Red spots of our graffiti
Make a chicken pox on you

We make the top skin separate
And fill the space with goo,
Small, itchy blisters are a stage
Of chicken pox on you.

And when the blisters break, my friend
You think perhaps we’re through
But no. Now there is a scab
For each chicken pox on you

Scratch a scab so it comes off
Baring skin that’s raw and new,
A scar forever marks the spot
Of that chicken pox on you.

The source? Chicken with fowl pox

To the battle, fellow viruses!
We’re more noteworthy than flu
They just make you feel sick
We make our chicken pox on you!

The Architect Who Hated Straight Lines

José Batlló’s house in Barcelona, Spain, was looking a little shabby. So, Batlló turned to Antoni Gaudí, the city’s most inventive architect—and got a house that astonished all Barcelona.

Its walls, studded with glittering blue and green shards, billowed like the sea. Some windows were egg-shaped, others had balconies resembling giant masks. The roof was more fanciful. Eerily iridescent, colors shifted from bluish green to golden orange. With scale-like tiles, it reminded people of a dinosaur’s backbone. Because of the oval windows, people called it the House of Yawns. Others, noticing columns that looked like shinbones, christened it House of Bones.

Born in 1852 into a family of coppersmiths, Gaudí grew up in a small town near Barcelona. As a boy he roamed the countryside making sketches, living in his own world of discovery and fantasy. Becoming an architect was his childhood dream.

He quickly developed a style entirely his own, drawing inspiration from nature rather than anything man-made. He was disdainful of straight lines. “They belong to men,” he used to say. “Curved lines belong to God.”

Near Casa Battló stands another Gaudi creation: Casa Mila, a six-story apartment building which, because of its soft swelling shapes, has been likened to human lips, pastries, and a hornet’s nest. Still, many people love it.

Among Gaudí’s accomplishments is what may be the world’s quirkiest park: Park Güell, a kind of fairy-tale fantasy, with two dancing gazelles flanking the entrance, a giant tile-encrusted lizard, and a roof topped with upturned coffee cups.

Deeply religious, Gaudí spent his last twenty years working on Sagrada Familia, a cathedral unlike any other, with eighteen towers symbolizing the apostles, evangelists, the Virgin Mary, and Christ. It became such an obsession with Gaudí that he set up residence at the worksite. Once something of a dandy, he became increasingly careless with his appearance. This neglect may have contributed to his death.

On a spring evening in 1926, taking one last loving look at a newly completed Sagrada Familia tower, he stepped off the sidewalk and was hit by a streetcar and knocked unconscious. Because of wretched clothing he was taken for a tramp and not immediately brought to a hospital. Gaudí was finally recognized, but was beyond help and died three days later.
