Pakistani youth activist Malala Yousafzai was awarded the 2014 Nobel Peace Prize on Friday, October 10th. She is the youngest Nobel winner in history. Malala shares the prize with Kailash Satyarthi, a 60-year-old man from India who has helped lead a movement to end child slavery around the world.

    Malala Yousafzai was born on July 12, 1997 in Mingora, the SwatDistrict of northwest Pakistan to a Sunni Muslim family. When she was just 11 years old, she started blogging about the Taliban take over of her hometown. Taliban members believe young girls should not go to school. Classroom sthrough out the Swat district were closed for several months. Malala spoke publicly about her desire to go back to school. “All I want is an education,”she told one television broad caster.

    When the Pakistani government regained control, Malala was able to return to class. She continued to blog and speak out about girls' right to education. But on October 9, 2012, the Taliban tried to silence her. Agunman boarded her school bus and shot her on the left side of her forehead. Malala survived, and showed great courage and optimism during her long recovery. Then she became a symbol of the struggle for girls' rights all over the world.

    Malala's mission for peace is unstoppable. Nine months after shewas shot, she gave a now-famous speech at the United Nations. “They thought that the bullets would silence us. But they failed,” she said. “And then, outof that silence came thousands of voice. Weakness, fear and hopelessness died. Strength, power and courage were born.”

    I was born in Thailand, where I feel at home. I am used to jumping on to a song taow (red taxi), and squeezing (挤过) in between two strangers. I am used to bargaining at the market to get a shirt that I like. I love telling bilingual (双语的) jokes and I am used to the surprised looks I get from the Thais when I can speak their language fluently.

    Every two years my family goes to America for the summer, and every two years my world is turned upside down. The prices of everything are three times what they were in Thailand, but there is the sweet drink Dr. Pepper! And Bluebell Ice-cream! And everything you could imagine! I am amazed at it all, but the biggest change for me is the people. There are white people everywhere. I am not tall but average (中等的), my yellow hair is no longer out of place, and speaking English no longer draws looks. I should feel comfortable. I'm not out of place anymore, and nobody is looking at me, but I feel like they are. Now I feel out of place and different. I'm not used to giving people handshakes and hugs when I meet them for the first time. I get looks when I have trouble figuring out how much money to pay. I know different music, different places, and different fashion. I can't understand these people who have never left their town or city.

    Still, there are quite a few perks about living overseas. I get to meet people from all over the world, and I know how to adjust to (适应) different cultures and places. I have been to places most people see only in geography books. Still, being so different makes it hard to know who you are. I'm not Thai, but I am not American either. I am a mix of both cultures, a third culture kid.

    We've considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing line-cutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service).

    Markets and queues—paying and waiting—are two different ways of allocating things, and each is appropriate to different activities. The morals of the queue, “First come, first served, have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.

    The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it's the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.

    Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank: “Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It's as if the company is trying to ease our impatience with fairness.

    But don't take the recorded message too seriously. Today, some people's calls are answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.

    Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other non-market ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queue-jumping schemes we've considered—at airports and amusement parks, in call centers, doctors' offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.

    Technology is always trying to meet our needs and demands. There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "recreate forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability (可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurant than homes and high-end restaurants.

    I decided to ski to the North Pole. It was after I saw an advertisement in a newspaper looking for people to join a team to ski 350 miles to the North Pole. Back in 1996, there had never been a woman from the UK who had accomplished this challenge. I wondered what it would be like to survive in temperatures cold enough to freeze your flesh in seconds, so I sent off for the application form.

    The application form full of pictures of male explores arrived. The words "Are you man enough for the ultimate（极限的）challenge?" made me angry and even more determined to get on the team.

    Over 500 individuals applied for a place in the team, and the selection process included physical and psychological tests designed to pick the best group. In one test, there was a huge rope ladder we had to climb, and I froze at the top because I have a fear of heights. I thought my hopes were fading as most other applicants sailed past, leaving me behind. But two others helped me over, and later I found out that the organizers were not looking for amazing individuals, but great team players, and this moment had shown them who would take care of others in the team.

    I had revealed（显示）my weakness, and in a place like the Arctic, you have to be yourself, as there is nowhere to hide. These personalities of asking for help and showing weakness are necessary for women to master.

    I realized that by being myself, I could succeed. I was selected for the team. I realized that I could achieve more than I ever imagined — more importantly, by sharing my story with others, I could inspire them to take a step into the new world and reveal more of their abilities.

    When my family moved to the United States from Colombia, I was 9 years old and knew little about English. As time passed, teachers finally knew all of their students and slowly everyone began to head inside, except for me. No one called out my name, and no one seemed to know I existed. I spent the next month in my new classroom quietly. I felt a wave of fear, loneliness and sadness came over me.

    It turned out the school administration never cared that I didn't speak English, but something else was teaching me English. Every morning when my aunt drove me to school and picked me up, she always had 106.7 Light FM on. It was this station that introduced my young ears to the English sounds of R&B, soul, jazz and much more.

Because of Sabrina the Teenage Witch, I learned the difference between "witch" and "which". While watching the TV show South Park, I was attracted by the funny characters. I related "You bastards!” to anger and saved it in my mental word bank. In fact, thanks to pop culture, the world of English became not so hard to me while it was being turned down at school.

    I also learned how to express my emotions thanks to pop culture. One day at school, we were taking a math quiz and the whole class was quiet. Suddenly, the tip of my pencil broke and I yelled, “You bastards!" Everyone held their breath in surprise and I laughed to myself because something at that moment told me I had just learned my first bad word in English.

    Four months passed before the school placed me into an ESL program. By this time, I was speaking broken English and making myself understood. Finally, I learned how to speak and write English at a more advanced level, and I owe it all to pop culture.
