SurvivingHurricane Sandy(飓风桑迪)

Natalie Doan, 14, hasalways felt lucky to live in Rockaway, New York. Living just a few blocks fromthe beach, Natalie can see the ocean and hear the wave from her house. “It'sthe ocean that makes Rockaway so special,” she says.

On October 29, 2012,that ocean turned fierce. That night, Hurricane Sandy attacked the East Coast,and Rockaway was hit especially hard. Fortunately, Natalie's family escaped toBrooklyn shortly before the city's bridge closed.

When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, peoplewere suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.

      In the following few days, the men and women helping Rock away recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping othersrebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings.

“ My mom tells me that I can't control what happens to me,” Natalie says. “butI can always choose how I deal with it.”

Natalie's choice was to help.

      She created a website page matching survivors in need with donors who wanted to help. Natalie posted introduction about a boy named Patrick, who lost his baseball card collecting when his house burned down. Within days, Patrick's collection was replaced.

      In the coming months,her website page helped lots of kids: Christopher, who received a new basketball; Charlie, who got a new keyboard. Natalie also worked with other organizations to bring much-need supplies to Rock away. Herefforts made her a famous person. Last April, she was invited to the WhiteHouse and honored as a Hurricane Sandy Champion of Change.

Today, the scars(创痕)of destruction are still seen in Rockaway, but hope is in the air. The streets are clear, and many homes have been rebuilt. “I can'timagine living anywhere but Rockaway,” Natalie declares. “My neighborhood willbe back, even stronger than before.”

    When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never yelled at us for playing in his yard, but was always very kind.

    When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle “No pain, no gain”. He hardly watered his new trees, which flew in the face of conventional(传统的) wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

    Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some twenty five years ago. They were all tall and strong.

    I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity(逆境) seemed to benefit Doctor Gibb's trees in ways comfort and ease never could.

    Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to meet with hardship. There's always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won't be torn apart.

    Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, "Take the extra minute to do it right." I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp comers of a glass coffee table.

    I don't only avoid those "if only" moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say "I love you" or "I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    The last time I visited my eighty­three­year­old mother­in­law, I asked how she was feeling. It's a valid question. She has, after all, had two knee replacements and a liver transplant. She moves slowly to avoid another fall.

    But she hasn't stopped moving. She and my father­in­law attended their first Jimmy Buffet concert this summer. Here's the thing about my in­laws: They never say no to an invitation or a new adventure. If they can make it work, they're willing to try just about anything. When we need them to come to stay with the kids, we have to get on their calendars far in advance.

When asked how she was feeling, my motherinlaw responded, "Well, everything hurts every day. But you know what I've discovered? It doesn't hurt to smile. So that's what I've decided to do... smile at everyone I see. I may not be able to do all the things I used to do, but I can at least brighten someone's day."

    It is such simple wisdom. Moving the focus from what we don't have and from what we've lost to what we can offer others is the difference between living in the dark and radiating light. They inspire us daily.

    The key to a life worth living, I think, is to change our views. You don't have to make great changes. Sometimes change looks similar to everyday kindness. Sometimes change begins with holding the door for a mother with an armful of groceries.

    In theory, the butterfly effect says that the smallest breeze(微风) from a butterfly's wing can change the path of a hurricane halfway. Imagine, then, the possibilities that exist within a single smile.

    Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.

    A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.

    According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.

    The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans.

    "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."

    An online supermarket company—Ocado in the UK, has recently displayed a robotic hand that can pick fruits and vegetables!

    When an embryo (胚胎) is in the womb, the very first sense it develops is touch. The sense of touch is also the one that lasts the longest—as we get older and our vision and hearing begins to weaken, touch still remains. Humans use their touch to protect themselves, to create emotional relationships with other people, and to experience pleasure. Can you imagine life without it?

    The sense of touch comes from a network of nerve endings and special touch receptors on the surface of the skin. While there are different kinds of touch receptors (感受器), they help us judge pressure, texture and vibrations (震动). They are located in our fingertips, palms, soles of our feet, face, lips and tongue.

    When we touch something, the mechano-receptors perceive the touch and through a network of nerves, send signals to the brain. This informs the brain about the location of the touch, the amount of force used, and the speed at which it was used.

    Several different techniques have been tried in the past to create such a robotic hand—using three fingers. But this latest design by SoMa copies the human hand. The gripper (夹具) is made up of flexible materials which grasp onto the thing based on its size and shape. Then air pressure is used to control the movement of the robotic fingers to pick objects safely and without causing damage.

    The next step would be for the robot to judge how ripe the fruits and vegetables are, and apply pressure accordingly. Members of the research team are currently working on adding computerized vision to the robots, so that they can see what they are gripping.

    Does all this mean robots can replace people? According to Ocado, it helps improve productivity by removing some of the repetitive tasks done by humans.
