In the fossilized feathers, researchers studied microscopic structures called melanosomes that give feathers their color. Based on the shapes of its melanosomes, they say this penguin wore reddish-brown and gray feathers instead of black and white. Even in the bird world, fashions can change from one epoch to the next. The biggest annoyance to astronauts on spacewalks isn’t echoing helmets or sweaty suits—it’s their painful gloves. Sometimes, astronauts complain, their gloves even make their fingernails fall off. When outside their spaceships, astronauts wear gloves that are pressurized to match Earth’s atmosphere. This makes the gloves stiff and difficult to move. Researchers guessed that astronauts with the longest fingers might have it the worst, bumping their fingertips into the hard ends of their gloves over and over. But, looking at data from 232 astronauts, they found that the biggest risk factor was hand width. Astronauts with the biggest paws had almost a 20 percent chance of fingernail injury because the gloves cut off their circulation.

In real life, for example, you almost never have to react to a heavily armed alien jumping out at you. But scientists say playing shoot-’em-up video games can improve your real-life ability to make quick decisions. Researchers looked at two groups of men around 19 or 20 years old. One group played “action” video games at least five times a week, and the other group never played them. In a test that involved making quick decisions about moving dots on a computer screen, the action-game players did better than the others. They also did better on a similar sound-based test. Though fast-paced video games may help you make quick decisions, they won’t help with decisions such as, “Should I pass this next level or do my homework?” Facebook for Real Most modern penguins look like miniature orchestra conductors in tuxedo jackets, thanks to their white and black feathers. But this wasn’t always the case, says researcher Julia Clarke. In Peru, Clarke and her team discovered a fossilized giant penguin 36 million years old. As if person-sized penguins weren’t exciting Students at Queen Victoria Junior High in Manitoba, Canada, were excited when their principal announced “Facebook for Real.” For one day, students and teachers would simulate everything they did on Facebook—from friending to Farmville—in real life. The social experiment started out enjoyably enough. Teachers Art from Katie Brown/University of Texas, Austin the head and torso a lot while dancing was a positive factor. So was “speed of movements of the right knee.” Keep that in mind at your next school dance. Hey, You with the Claws. Don’t I Know You? To us, all lobsters might look the same. But research from the University of Florence in Italy suggests that lobsters can recognize each other by sight. When two male lobsters meet, they size each other up and make threatening gestures. Then they usually fight. Researchers paired off 98 male American lobsters in tanks, first with a clear or opaque wall between them, and then with no walls. They found that lobsters that had already “met” through a clear wall went straight to fighting once the wall was gone. Lobsters that were strangers, though, spent more time threatening each other first. Scientist Puts Socks over Shoes, Wins Prize Scientifically Proven Dance Moves What makes a guy a “good” or a “bad” dancer? To find out, a team of British researchers recruited 19 men and recorded them with cameras while they danced. T hen they transformed each recording into a computerized avatar and had a group of women rate the digital dancers. (They used avatars so women wouldn’t be biased by how attractive or unattractive the real men were.) Which dances got the highest ratings? Moving Not everyone can win a Nobel Prize. For scientists whose research is on the sillier side, there are the Ig Nobels. T he 2010 Ig Nobel Prize in Physics went to New Zealand researcher Lianne Parkin, who showed that wearing socks outside your shoes can keep you from slipping on winter ice. At the University of Otago, Parkin’s group recruited students and others who were on their way down a steep and icy hill. They gave half the recruits acrylic-blend socks to put over their shoes, then sent them on their way. At the bottom of the hill, participants rated the slipperiness of their trip. Those with socks over their shoes did, in fact, find the hill less slippery. (Observers confirmed that the sock-wearing group was less likely to cling to fence posts on the way down.) The only downside to this technique, Parkin observed, was “short periods of indignity.” The false story is “Facebook for Real.” Photo from Northumbria University passed out thumbs-up stickers, representing Facebook’s “Like” button, which students could give to classmates who shared good ideas in class. And a local farm lent the school three goats and a pig for the day so students could play “Farmville” on the practice field. But manure from the animals accumulated rapidly, since students refused to clean it up. “Like” stickers became a straightforward popularity contest, hurting many students’ feelings. And poking battles broke out in some classrooms. Did the experiment have any lasting effect? Eighth-grader Marcia Zimmerman says Facebook “doesn’t seem as cool anymore.” School administrators won’t say whether that was the whole point. I n the fall of 2008, the John G. Shedd Aquarium in Chicago began renovating its Oceanarium, a big indoor pool that houses seven beluga whales and four Pacific white-sided dolphins. When humans renovate their own homes, they might stay in a hotel or with relatives to avoid all the hammering and paint fumes. Large marine mammals, though, are a little trickier to relocate. With a lot of teamwork and just a few forklifts, the Shedd staff managed to FedEx their animals across the country and back. If you ever need to plan a vacation for any of your own dolphins or whales, their story will certainly be of help to you. Step 1: Plan Ahead. Moving 11 dolphins and whales is, as you might guess, not easy. Ken Ramirez, the aquarium’s senior vice president of animal collections and training, says it took more than five years for aquarium staff to plan the renovation and marine mammal “vacation.” Their biggest task wasn’t figuring out how to mail a whale, though, but where to mail one. In their search for an institution that could take good care of all their whales and dolphins, they thought they’d have to split up the group between three different temporary homes. But finally, they discovered that the Mystic Aquarium and Institute for Exploration, in Connecticut, would be happy to take all 11 animals. Once they’d chosen their destination, the Shedd staff worked with FedEx to plan the move. To carry all their animals almost 1,000 miles (1,600 kilometers) to Connecticut would take two separate planes. The team had experience with transporting these animals, though they’d never organized such a large move before. Ramirez says the animals weren’t rookies, either: “Many of our whales are experienced travelers, and our younger whales [were] prepared for the transport through practice sessions prior to leaving.” 24 text ©muse 2010 by Carus Publishing Company Photos by Brenna Hernandez//© John G. Shedd Aquarium, Chicago Step 2: Lift from Your Knees. Being practiced travelers, the whales and dolphins helped their transport team by swimming into the hammocks that would carry them. Once in their hammocks, the smaller dolphins (the smallest weighs about 200 pounds, or 90 kilograms) could be lifted and carried by staff members. The larger animals (the largest beluga weighs 2,000 pounds, or about 900 kilograms) and their hammocks had to be hoisted with special carts, forklifts, and cranes. (One can only imagine what goes through the head of a one-ton whale that suddenly finds itself airborne.) The whole group of animals was moved in two batches, over the course of two weeks. It was a team effort, Ramirez says: “Between the staff at Shedd Aquarium, the truckers who assisted us in moving from Shedd to O’Hare Airport, the airport staff, the FedEx staff, the airport staff in Connecticut, trucking staff on that end, and the staff at Mystic Aquarium, we required over 200 people for each move.” Step 3: Find a Really Big Box. The whales and dolphins skipped the security line and boarded the airplanes in specially designed “cradles.” From the outside, these looked like giant boxes with no tops. Inside, each cradle held two feet of water. The animals’ hammocks rested inside so that the water supported their weight and kept them cool, but they could also breathe comfortably. (Remember, even though whales and dolphins live in the water, they breathe air just like any other mammal.) Though these whales and dolphins normally live in salt water, their cradles were filled with fresh water—salt water, which can leave behind a corrosive buildup, would have been dangerous to the airplane’s wires and electronics. Filled with water and whale, the largest cradle weighed 18,000 pounds (about 800 kilograms). Good thing they didn’t take it to the post office—that would have been a lot of stamps for someone to lick. muse 25 Step 4: Make Sure Contents Are Packed Securely. Each animal was accompanied by a trainer who knew it well. Although they knew the animals would be safe, the trainers sat inside their cradles to keep them company. Ramirez says that having a familiar adult nearby keeps the animals calm and comfortable, making traveling with a whale “very much like traveling with children.” Except the whales and dolphins don’t bicker with each other in the back seat. Step 5: Go Sightseeing. Twelve Shedd staff members moved to Mystic to stay with the animals for their eight-month visit. Ramirez says that for the animals, life at Mystic was a lot like life in Chicago: “We continued to play with and interact with them every day, as we always did at Shedd. We fed them the same type of fish, we brought their favorite toys.” And obviously a whale can’t really get out and see the sights. Still, the animals were used to their indoor habitat in Chicago, so the outdoor pool at Mystic brought many new experiences. Ramirez says they “had to learn about seagulls, rain, snow, wind, and bright sunshine.” But with their trainers keeping them company, the animals easily adjusted to all these changes. Step 6: Welcome Your Whales Home. After eight months of vacation at Mystic, the whales and dolphins (and their trainers) made a return journey to Chicago. “The homecoming was wonderful!” Ramirez says. Although the Oceanarium had been renovated, its basic layout remained the same. Ramirez says, “There was no question that they knew they were back. We could tell by their swimming patterns and familiarity with everything that they were very pleased to be home.” The staff could also tell that the animals noticed the changes that had been made while they were away. Staff members who had stayed behind were thrilled to be reunited with the travelers. And visitors to the aquarium, of course, were happy to have everyone home again. Virginia Edwards is a writer living in Chicago. Her favorite animal at Shedd Aquarium is the sawfish, which has a head shaped like a guitar. She wouldn’t necessarily want to accompany it on a cross-country flight, though. by Robert J. Coontz and Rebecca Lasley art by Slug Signorino Q: Why does watching a 3D movie with glasses make your eyes hurt after a while? A: Q: Do crocodiles have tear ducts? What are “crocodile tears”? text © 2010 by Robert J. Coontz and Rebecca Lasley art © 2010 by Slug Signorino A: —Tzipporah K. The popular meaning of “crocodile tears”—a fake display of sadness—dates back at least to the Middle Ages, when people believed crocodiles cried over their victims. “If the crocodile findeth a man by the brim of the water, or by the cliff, he slayeth him if he may, and then he weepeth upon him, and swalloweth him at the last,” Bartholomew Anglicus wrote in his 13th-century forerunner to the encyclopedia. No one seems to have thought the crocodile might weep out of genuine remorse! Some people also believed that crocodiles cried to lure victims to their doom. Shakespeare imagined how “the mournful crocodile with sorrow snares relenting passengers.” Crocodiles do cry, and their tears, like ours, spill out through tear ducts. Crocodiles don’t cry out of sadness, though—genuine or phony. They tear up as a purely practical matter, to keep their eyes moist. “Tears are normally only noticeable if the crocodile has been out of the water for a long time and the eyes begin to dry out,” says zoologist Adam Britton. Crocodiles have three sets of eyelids, and they need the moisture to keep everything working smoothly. —Rebecca —Courtenay, age 12 Some scientists think it’s the movies’ fault. Nick Holliman, head of the Innovative Computing Group at Durham University in England, researches ways to make them easier to watch. When you look at the real world, he tells me, each of your eyes sees a slightly different picture. Your brain uses those to calculate depth, the third dimension in “3D.” A 3D movie fools your brain by artificially making two images and sending one to each eye. (That’s what the special glasses are for.) Those images, Holliman says, are calculated for an average viewer with eyes an average distance apart. If you’re not average, they can make you uncomfortable. Showing a movie on the wrong-sized screen can also exaggerate the 3D effects enough to cause pain. Even when a movie “fits” your eyes, it still makes them do strange things. Martin Banks, a professor of vision science at the University of California, Berkeley, has studied some of them. To watch an object in real life, he explains, your eyes have to do two things at once: stay pointed at it, and stay focused on it. Normally, the pointing and focusing distances are the same. At a 3D movie, though, they’re different: Your eyes point at whatever you think you’re seeing in the movie, but they have to focus on the screen. Your eye muscles aren’t used to doing that trick, and it makes them tired. Result: eye aches. —Robert Have any questions you want answered? Send them to MUSE Q&A, 70 E.

But his mom was a regular, mortal woman. nce there was a very, O very strong Greek guy named Hercules. “This is my only appearance in the story!” “Actually, it’s Heracles.” Hera, the queen of the gods and Zeus’s wife, was not thrilled with Zeus’s fooling around. OK, it’s Heracles, but the Romans changed it to Hercules, so we’re going with that. Hera even tried to kill off baby Hercules by sending some snakes after him. Despite Hera’s efforts, Hercules survived to adulthood, married a woman named Megara, and had a bunch of kids. “We’re going to have a long and happy life together! Don’t count on it, honey. text © 2009 by Carus Publishing Company; art © 2009 by Kali Ciesemier ”” Hera hatched a new plot to ruin Hercules’s life. She made him lose his mind . . .

First, Hercules had to kill the Nemean lion, whose hide was so sturdy it couldn’t be penetrated with arrows or swords. I am your slave. Woohoo!” “Woohoo!!” What have I done?” As punishment for killing his family, Hercules was sentenced to serve a king named Eurystheus for 12 years. Eurystheus was pretty scared of his extremely strong, family-murdering slave, so he preferred to address Hercules from inside a big jar. No problem.” The hydra was a nasty, swamp-dwelling monster with nine heads. Or 10,000 heads, depending who you ask. Yo, I killed that big cat and made a handy impenetrable cloak out of its skin. You mean you still haven’t killed the hydra?” Hercules defeated the hydra by burning its head stumps before they could grow back. At the same time, he killed a big assassin crab sent by—guess who?—Hera. Oh, and whenever Hercules cut off one of the hydra’s heads, two new heads grew in its place. Next, our hero had to capture a one-of-a-kind deer with golden horns and bronze hooves. This was a little tricky because the golden deer belonged to the goddess Artemis. Hey!” muse 11 The Erymanthean boar, a giant wild pig that enjoyed goring people with its tusks, didn’t give Hercules much trouble. King Augeas had thousands of cattle, sheep, and horses in his stables. Unfortunately for the animals, he was too lazy to clean up after them. “Well, don’t give him to me! Go clean out the Augean stables!” Hercules didn’t want to spend the next 10 years shoveling poop, so he moved a couple rivers to do the dirty work for him. “I’m strong AND clever!” Hercules killed some birds that were terrorizing the town of Stymphalos . . . “Birds? Really?” They EAT PEOPLE!!” Eurystheus still had plenty of tasks left for Hercules. . . . and stole some horses from a king named Diomedes. “Horses? . . . Really??” . . . captured a crazy bull that was bullying Crete . . . Stealing a fancy belt that belonged to Hippolyte, the queen of the Amazons,* gave him a little more trouble. Get ’’im, ladies!” They EAT PEOPLE!!” *The Amazons were warrior women who had nothing to do with the Amazon River. Geryon had three heads and six legs. Eurystheus must have been running out of ideas at this point: for his tenth labor, he told Hercules to steal even more cattle. These ones were giant and red, and belonged to the monster Geryon. “Let’s go.” ! ρκ βά . . . And a two-headed dog!” In the home stretch, things got more complicated. Hercules needed to acquire some golden apples. Unfortunately, the apples belonged to Hercules’s old enemy, Hera. Hercules enlisted help from Atlas, a guy whose job was to hold up the earth. “I’ll take that off your hands for a minute if you’ll go grab a few golden apples for me.” Atlas got the golden apples, and then proved not to be very smart. “Say, it feels pretty nice not to be holding up the earth anymore. How ’bout you stay there forever?” “Sure, no problem. Can you just take this for two seconds while I, um, scratch an itch?” For his final task, Hercules simply had to borrow a dog named Cerberus. Of course, Cerberus’s owner was Pluto, the god of the underworld. So Hercules had to take a little trip. Don’t worry, he returned the dog later. All right, Hercules, it’s been 12 years, so I guess you’re free. “Woohoo!” What do you people feed your dogs?? He EATS PEOPLE!!” Once Hercules had completed his 12 labors in 12 years, he was free to live out his life. In the end, what killed the brave hero was not a fearsome, multiheaded creature, but a simple cloak that had been poisoned with— No! No. That story’s too embarrassing. The end. The end!” . . . Fine. THE END. A Mathematical by Cynthia Graber The Makings of a Mathematician When Annalisa Crannell was a young girl, her family’s dinner conversation focused on math and science. Her dad was a nuclear physicist who studied the size of protons (one of the parts of an atom). Her mom was a solar astrophysicist who worked at the Goddard Space Flight Center near Washington, D.C. “She really was a rocket scientist!” Crannell says. Crannell couldn’t help picking up the language her scientist parents used and their casual way of bringing math into their everyday lives. One time, walking home from school with a friend, she said, “If we go to your house instead of mine, we’ll get more work done per unit time.” She laughs at this memory: “I realized other kids didn’t say ‘per unit time.’” Math wasn’t always easy for her, though. When she took algebra, she felt overwhelmed by word problems and the need to think through the steps to solve them. Her dad intervened and helped her out. He said, she recalls, “You hate word problems? I love word problems. If you just keep going, you can get them done.” He wouldn’t let her give up, and he Even though it’s math, Annalisa Crannell’s class is not all serious. (Except for the noses. Those are serious.) text © 2011 by Cynthia Graber S tare through a window at the buildings and trees outside. How would you draw these so that they look realistic? It may surprise you to learn that mathematics can help. To Annalisa Crannell, a professor of math at Franklin and Marshall University in Lancaster, Pennsylvania, math and art make a perfect couple. Math can help explain why great art looks so realistic, and understanding math can help artists learn how to draw buildings and plants. Crannell’s own research focuses on chaos theory, which is the idea that one very small change in a system can have a big, unexpected impact. But she has also become famous for joining mathematics and art through classes she teaches at the university. In fact, she worked with a colleague to write a textbook about perspective and geometry in art, which will be published this year. Math, she says, can help explain how to draw and paint images from the real world, transforming what we see in the three-dimensional scenes around us onto the two-dimensional surface of a piece of paper or an artist’s canvas. Perspective wouldn’t let her say that she hated math. He helped her gain confidence to face difficult problems and figure out the answers. When Crannell started attending Bryn Mawr College, near Philadelphia, she didn’t immediately gravitate toward math. Instead, she thought she wanted to study foreign languages and become a tour guide in her hometown of Washington, D.C. But her father convinced her to at least try one math class, because she had been good at math in high school. Luckily, she had a great professor named Mario Martelli. She did so well in his class her freshman year of college that Martelli took her aside after the semester was over and suggested she take another class with him that same year. But that class was primarily geared toward seniors, who were three years ahead of her in school. Her professor had such confidence in her abilities that she dove in, and she strove to live up to his expectations. She thrived in the class and continued on with math, eventually earning her PhD. Crannell is still in touch with Martelli, her first college math teacher, and they’ve even published math research papers together. “He was a huge influence on my life,” she says. “I’m lucky I got into his class.” Making Math Visible Annalisa Crannell was originally inspired to teach a class on math and art as a way to make math less, well, scary. She knew that some students, particularly girls, believe that math is beyond their abilities. But when students can see how math connects to their own interests and experiences, the subject becomes significantly less intimidating. She thought she could make math tangible, and visible, by showing her students the geometry in the world around them—in neighborhood buildings, for example, or in plants. A piece of paper, she says, is like a window onto the world. Turning the three-dimensional world of buildings, streets, and trees into a two-dimensional picture, or window, involves the field of geometry. For instance, the sides of a street in real life are parallel. But if you stare at them out a window, they might look as if they’re coming to a point in the distance. That’s called the “vanishing point.” Another way to picture this is to think of drawing a box. The front of the box is a normal square. But to make the box a cube—in three dimensions—the sides of the box need to look longer as they stretch toward the back, or toward the vanishing point. So instead of drawing squares on the sides of the box, you have to draw trapezoids. Another important part of perspective is the horizon line, the place where the ground meets the sky. What’s interesting about both the vanishing point and the horizon line, Crannell explains, is that they are determined by the location of the artist. For instance, if you’re the artist drawing a box, and you’re above the box, you’ll draw the vanishing point above the box. If you’re below the box, the vanishing point goes below. The vanishing point tells you where the artist stood. to teach her students to have a greater appreciation of works of art they might see hanging in homes or museums. Teaching art has also helped Crannell see the world through a different lens. “I walk down a hallway, and I see the vanishing point at the end of the hallway where I never saw it before. I can see how a door recedes away from me,” she describes. She likes to doodle in a sketchbook, drawing the shadows of buildings as the sun moves across the sky and figuring out what mathematical equations could predict where those shadows will fall. Crannell says, “Really beautiful mathematics allows you to make a really beautiful picture.” Cynthia Graber is a journalist living in Massachusetts. Her greatest artistic achievement was painting a dolphin and a polka-dot jellyfish on her old car. Perspective helps people draw structures with straight lines, like streets and buildings. A fractal, on the other hand, is a geometric pattern in which a tiny piece of the object looks the same as the whole thing. Fractals describe many objects in the natural world: trees, clouds, and broccoli, for example, all tend to be fractals. A small floret of broccoli looks remarkably like the entire broccoli head. A Different Lens Understanding math helps Crannell’s students become better artists. It also helps them understand how artists created their paintings. To get a perfect sense of proportion in a painting, a viewer should be standing right where the artist was when he or she painted it. Crannell points out that some museums in Italy actually mark a point on the floor in front of a painting where you should stand to get the best sense of perspective. (Though it might not work if the artist was six feet tall and you’re only four feet: even if you stand in the same place, you won’t have the exact same view!) She uses math St. Jerome in His Study, a 1514 engraving by German artist Albrecht Dürer, has strong perspective lines (which we’ve highlighted in color). It also has a lion. From Stick People to Star Artist Before. After. Carra Kramer, a junior in college, signed up for Annalisa Crannell’s math and art class in her first year at Franklin and Marshall University. “I was really into math, and I also really liked art when I was in high school. I thought combining the two could be interesting,” says Carra. But it wasn’t easy! The first drawings she turned in, as she describes them, looked like stick figures. (You can see her first drawing to the left, above.) Every week, she and her classmates drew and learned about math. They focused on perspective and how to measure it, and how to draw objects so they look realistic. They also learned to look at art to understand how the artist used perspective in the drawing or painting. Carra says she learned how complicated it was to draw—complicated, but not impossible. As the class progressed, Carra was able to use math to replicate real-life objects in her drawings. Understanding perspective helped her figure out how lines should be angled. Learning about fractals helped her draw patterns in plants. In fact, she and her classmates started seeing math everywhere they looked. “It got to the point that I’d walk outside and look at a tree, and all I could see were fractals! Instead of appreciating the tree, I was appreciating the math in the tree!” she says, laughing. She worried that the class might end up ruining her experience of trees, but that never happened. It certainly did help improve her artwork, though. At the end of the class, Carra used the geometry of vantage points and the horizon line to draw her dorm building and the buildings nearby. You can see that final result to the left, below.

All of a sudden I am pulled from my happy place by a voice: “OK, you guys can start putting your sacks on!” I let out a dramatic sigh and snap back into reality: I am squished sitting three-to-a-seat on a school bus on a rainy and hot (and thus very humid) July day wearing a long-sleeved shirt, long jeans, and high-top work boots at 5:40 in the morning, ready to take part in an Iowa tradition for teenagers. I groan as the people on both sides of me begin attempting to put on their variously sized garbage bags. I wiggle my arms out and put on my own 55-gallon trash bag like a rain poncho.

There are machines that do this, but they miss some tassels due to the varying heights of the plants. Detasselers are there to pick up the slack. We do this because years ago, farmers got the idea to breed together two different types of corn to make a hybrid “super-corn.” They grow one row of “male” corn (corn that keeps its tassel) for every six rows of “female” corn (corn that is detasseled). You walk in groups of six down a panel (that’s the six female rows) and pull off all of the tassels. You come back a few days later to check the field and get any tassels you might have missed. After all of the tassels from the “female” plants have been pulled, the corn grows and the “male” corn’s tassels open up and release pollen to fertilize the “female” corn. Shazam!

Up at 4:30, at the bus stop by 5:25; the crowd on the bus getting progressively smaller as many decided this was not the work for them; baking two batches of cookies to bring on my brother’s birthday; freezing corn plants in the morning, blazing sun by day; sunburn on the back of my neck and on my wrists between the gloves and shirt, the only exposed parts of my body. Last day. I smiled. I was delighted when we arrived at a very small field, meaning a very short day. Everyone had a panel to themselves. I started singing as I walked quickly down the panel. I had gotten much faster and could identify a tassel in a single glance. After completing the last panel, I was overjoyed. I’m done! The bus ride back was the best one ever. I could hardly wait until the next morning, when I would sleep as long as I desired. Getting off the bus, my brother and I headed to our car. I gave one of my new friends a quick goodbye hug. “Are you coming back next year?” she asked. “Oh yeah!” I said without thinking. Looking back, I’m sure I will. It may not have been the most fun, but it’s an Iowa tradition. After all, we are the Corn State. text © 2010 by Carus Publishing Company The bus quieted as our supervisor stepped on to make morning announcements. He then started reading off names. Hearing mine, I worked my way to the front of the bus through the mass of sleep-deprived teenagers. I was given a neon orange hat with a face net, bright yellow safety glasses, and a pair of work gloves. This, plus the garbage bag, is the complete set of safety equipment for detasselers. The garbage bag may not be fashionable, but it keeps us somewhat dry from the ever-falling rain or morning dew. My group assembled and headed toward the cornfield. We were assigned our panels and lined up. Our checker (a more experienced detasseler who walks behind us and picks the tassels we miss) told us to go, and with a deep breath I plunged into the leafy green abyss. Although it was only 6:00 in the morning, I was wide awake now as the icy-cold leaves drenched my sleeves, already damp from the rain. I moved slowly at first. Each time I pulled a tassel, I heard a satisfying squeak or pop. Hey, this is actually kind of fun! The day dragged on without the rain letting up. $7.75 an hour . . . $7.75 an hour . . . We did row after row, and the rain began to soak up our legs and down our arms. Finally, wet and miserable, we all piled on the bus to head home. More than 45 rain- and dew-soaked teenagers were squished together, most telling themselves they would certainly not be returning the next day. This was going to be a long few weeks. MUSE muse 19 muse 25 What’s Wordle? in a by Elizabeth Preston L et’s say you just read a really fascinating magazine article and you want to tell your friend about it. You could compose a few sentences that efficiently summarize the story. You could perform the story in interpretive dance. Or—if your feet are tired and your summarizing skills are shaky— you could turn the article into a cloud of words. A computer program called Wordle, which you can try out for yourself at www.wordle.net, lets you do just that. The program simply asks you to “paste in a text © 2011 by Carus Publishing Company bunch of text,” though you can type something instead. Wordle then combs through your text and counts how many times each word appears. The more frequently a word is used, the larger it will appear in the resulting cloud. The world cloud below was made from the article “From Six Degrees to Facebook” on page 6 of this issue. Creator Jonathan Feinberg says he designed Wordle more for fun than for function—the point isn’t to get a lot of information across. But the image can certainly give you a feel for the text. In this cloud, the article’s most important themes (people, friends, degrees of influence) jump to the forefront. The details of the article (Facebook, Friendster, links, sites, students) hover in the background. You can adjust the colors, font, and layout of your Wordle to your heart’s content. You may notice something missing, though. The program removes “stop words,” the short, ordinary words such as prepositions and conjunctions that glue together the more interesting words. A cloud that displayed the, and, and of as its biggest words wouldn’t be very fun or functional. Savvy readers may be able to guess where the Wordle above came from: it uses every Muse Mail letter published so far in 2011. (Talk about a “bunch of text.”) It’s no surprise to see words such as Dear, Muse, and magazine featured prominently. Kokopelli is the most-mentioned Muse—a piece of news that will surely go to his head. A few of readers’ favorite subjects—pie, hot-pink bunnies, science, animals—lurk in smaller type. Among the Muses, poor Bo is somewhat neglected. Among states, a lot of readers seem to come from California. Why age? It’s a part of every letter’s signature. You might deduce from this Wordle that Muse readers always have one more thing to say. Also appears in both its capitalized and lowercased form, since the program counts them separately. If the two Make your own at www.wordle.net. forms were counted together, also would be an even bigger word in the cloud. (Also! Don’t forget P.S.) Jonathan Feinberg was inspired to create Wordle in 2004 by looking at so-called tag clouds online. A “tag” is a label such as sports or humor added to a blog post or other online article. Tag clouds display all of a site’s possible tags at once in a straightforward blob shape. Feinberg wanted to create a new kind of cloud that would be attractive as well as informative. Since then, people have found all kinds of creative uses for the program. “My wife has made some beautiful [art] prints from Wordles,” Feinberg says. “I’ve been happy to see Wordles used very artfully in newspapers, magazines, and blog posts. I’ve also seen Wordles used by some people to express thoughts or feelings that they’d otherwise find too painful or embarrassing to share directly.” He thinks the “easy creativity” of Wordle is what draws people in—anyone can be an artist, and any piece of text can become art. Plenty of people have been drawn in, and they’ve saved more than three million Wordles to an online gallery. Feinberg says that these days, he doesn’t create very many Wordles himself, though he did use Wordle to create an illustration for a book chapter he wrote. “When I do want it, I’m very glad it’s there,” he says. MINDING OUR BEESWAX To see more photos and learn more about Rooftop Honey, visit www.musemagkids.com/explorations. 1st printing Worldcolor Midland, Michigan July 2010 text and photos © 2010 by Carus Publishing Company T o see them hurrying through the downtown streets with their briefcases and iced lattes, you might think the businesspeople are the busiest workers in Chicago. But hidden high above their heads, another workforce is buzzing away: hundreds of thousands of honeybees, hard at work making Chicago Rooftop Honey. The rooftop workers live in eight hives on top of three downtown buildings, including City Hall. The hives are maintained by a group called the Chicago Honey Co-op, which also runs a bee farm and community garden on the city’s west side. Here, you can see co-op director Michael Thompson checking on a hive in the spring. As the weather warms, the hives will quickly fill with bees—a queen can lay as many as 2,000 eggs a day! Thompson will gradually stack more compartments on the hives to encourage the bees to store extra honey. In July and August, co-op workers will haul away the “ripe” honeycombs that bees have capped with wax. Then they’ll remove the wax, spin the combs to drain out the honey, and sell it downtown. Proceeds from Rooftop Honey benefit the city’s cultural programs, such as theater and concerts. Mayor Richard Daley started the program in 2003. All three of his beehive buildings also have “green roofs,” rooftop gardens planted over a waterproof layer. Chicago has more than 400 of these roofs, which save energy by keeping buildings warmer in the winter and cooler in the summer. The plants also remove carbon dioxide and pollution from the air, and provide an urban oasis for birds and butterflies. Why urban bees? “Raising honeybees can be more successful in cities than in rural areas because of the variety and density of flora in urban areas,” Thompson says. “It connects people to nature. And it teaches all of us that it’s safe to have dangerous insects downtown, where there are millions of people.” (He admits, though, that he’s been stung a few times.)
