I still remember my first day at school in London and I was half-excited and half-frightened. On my way to school I wondered what sort of questions the other boys would ask me and practiced all the answers: “I am nine years old. I was born here but I haven't lived here since I was two. I was living in Farley. It's about thirty miles away. I came back to London two months ago.” I also wondered if it was the custom for boys to fight strangers like me, but I was tall for my age. I hoped they would decide not to risk it.

    No one took any notice of me before school. I stood in the center of the playground, expecting someone to say “hello”, but no one spoke to me. When a teacher called my name and told me where my classroom was, one or two boys looked at me but that was all.

    My teacher was called Mr. Jones. There were 42 boys in the class, so I didn't stand out there, either, until the first lesson of the afternoon. Mr. Jones was very fond of Charles Dickens and he had decided to read aloud to us from David Copperfield, but first he asked several boys if they knew Dickens' birthplace, but no one guessed right. A boy called Brian, the biggest in the class, said: “Timbuktu”, and Mr. Jones went red in the face. Then he asked me. I said: “Portsmouth”, and everyone stared at me because Mr. Jones said I was right. This didn't make me very popular, of course.

    “He thinks he's clever,” I heard Brian say.

    After that, we went out to the playground to play football. I was in Brian's team, and he obviously had Dickens in mind because he told me to go in goal. No one ever wanted to be the goalkeeper.

    “He's big enough and useless enough.” Brian said when someone asked him why he had chosen me.

    I suppose Mr. Jones, who served as the judge, remembered Dickens, too, because when the game was nearly over, Brian pushed one of the players on the other team, and he gave them a penalty (惩罚). As the boy kicked the ball to my right, I threw myself down instinctively (本能地) and saved it. All my team crowded round me. My bare knees were injured and bleeding. Brian took out a handkerchief and offered it to me.

    “Do you want to join my gang (帮派)?” he said. At the end of the day, I was no longer a stranger.

    Are you so sure your mistakes are just mistakes? Or could they be building blocks to a success beyond any you imagined?

    When my friend Dorothy goes home to visit her family each Thanksgiving, her mother serves the traditional “mistake salad”. The dish was born many years ago. Dorothy explains, when mother was using a cookbook to make a salad. In the process, mother accidentally included half the salad ingredients(原料)from a recipe(食谱)on the left side of the open cookbook, and half the ingredients from a different salad recipe on the opposite page. Everyone enjoyed the salad so much that she continue to serve it every year. So it was really not a mistake at all.

    Then there was the fellow named Alfred, who invented dynamite(炸药). When Alfred's brother died, the city newspaper confused the two and printed an abituary(讣告)saying that the dead's most notable act was the creation of bombs. Surprised to consider that his name would forever be connected with destruction, Alfred sought to leave a more positive fame to humanity. So he set a prize for people who contributed to world peace. Now the Nobel Prize, established by Alfred Nobel, is the most respected award in the world.

    Everything is part of something bigger, and mistakes are no exception. In his brilliant book Illusions, Richard Bach explains that every problem comes to you with a gift. If you focus only on what went wrong, you miss the gift. If you are willing to look deeper and ask for the bright, the problem will disappear. You are left only with the learning, and you go forward on your path.

    I remember meeting him one evening with his pushcart. I had managed to sell all my papers and was coming home in the snow. It was that strange hour in downtown New York when the workers were pouring homeward in the twilight. I marched among thousands of tired men and women whom the factory whistles had unyoked. They flowed in rivers through the clothing factory districts, then down along the avenues to the East Side.

    I met my father near Cooper Union. I recognized him, a hunched, frozen figure in an old overcoat standing by a banana cart. He looked so lonely, the tears came to my eyes. Then he saw me, and his face lit with his sad, beautiful smile-Charlie Chaplin's smile.

    "Arch, it's Mikey," he said. "So you have sold your papers! Come and eat a banana."

    He offered me one. I refused it. I felt it crucial that my father sell his bananas, not give them away. He thought I was shy, and coaxed and joked with me, and made me eat the banana. It smelled of wet straw and snow.

    "You haven't sold many bananas today, pop, "I said anxiously.

    He shrugged his shoulders.

    "What can I do No one seems to want them."

    It was true. The work crowds pushed home morosely（愁眉苦脸的）over the pavements. The rusty sky darkened over New York buildings, the tall street lamps were lit, innumerable trucks, street cars and elevated trains clattered by. Nobody and nothing in the great city stopped for my father's bananas.

    "I ought to yell," said my father dolefully. "I ought to make a big noise like other peddlers, but it makes my throat sore. Anyway, I'm ashamed of yelling, it makes me feel like a fool. "

    I had eaten one of his bananas. My sick conscience told me that I ought to pay for it somehow. I must remain here and help my father.

    "I'll yell for you, pop," I volunteered.

    "Arch, no," he said," go home; you have worked enough today. Just tell momma I'll be late. "

    But I yelled and yelled. My father, standing by, spoke occasional words of praise, and said I was a wonderful yeller. Nobody else paid attention. The workers drifted past us wearily, endlessly; a defeated army wrapped in dreams of home. Elevated trains crashed; the Cooper Union clock burned above us; the sky grew black, the wind poured, the slush burned through our shoes. There were thousands of strange, silent figures pouring over the sidewalks in snow. None of them stopped to buy bananas. I yelled and yelled, nobody listened.

    My father tried to stop me at last." Nu," he said smiling to console me," that was wonderful yelling, Mikey. But it's plain we are unlucky today! Let's go home."

    I was frantic, and almost in tears. I insisted on keeping up my desperate yells. But at last my father persuaded me to leave with him.

    Why do you go to the library? For books, yes--but you like books because they tell stories. You hope to get lost in a story or be transported into someone else's life. At one type of library, you can do just that--even though there's not a single book.

    At a Human Library, instead of books, you can "borrow" people. Individuals volunteer as human "books" and participants in the event can "read" the book--meaning they would have a one-on-one conversation with the volunteer and share in a dialogue about that individual's experience. "Books" are volunteers from all walks of life who have experienced discrimination (歧视) based on race, religion, class, gender identity, age, lifestyle choices, disability and other aspects of their life

For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating and as attractive as any you can find in a book. Many of the stories have to do with some kind of stereotype. You can speak with a refugee (难民), a soldier suffering from PTSD, a homeless person or a woman living with HIV. The Human Library encourages people to challenge their own long-held beliefs-to truly get to know, and learn from someone they might otherwise make a quick judgment about.

    According to its website, the Human Library is "a place where difficult questions are expected, appreciated and answered." It provides the opportunity for the community to share and understand the experiences of others in their community.

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Ronni Abergel, his brother Dany, and some colleagues hosted a four-day during a major Northern European festival, hoping to raise awareness about violence among youth. After the success of this event, Abergel founded the Human Library Organization, which has been growing ever since.

    Though there are a few permanent human libraries, most aren't places at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio.

The stories these "books" tell range from fascinating to heartbreaking and everything in between. And that's the very point of the organization--to prove that no person can be summed up in just one word. It seeks to show people that you truly can't judge a book by its cover—or by its title or label.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
