How much do you know about Albert Einstein?

Albert Einstein, born on March 14, 1879 in Germany, was a great scientist in the world. He was strange because he hated haircuts and new clothes. He believed in peace. All his life, he hated war. However, his most famous idea, E = mc², helped create the world's most dangerous weapon (武器). Many people think he was the smartest person in the world. But Einstein said that he thought like a child with many questions and unusual ideas.

What did he like?

Einstein liked learning sailing(帆船运动). He sailed in small boats all his life.  Heonce joked, "Sailing is the sport that takes the least energy!”

When Einstein was a child, his mother made him take violin lessons. At first, he didn't like the violin. But then he learned to love music and became a good violinist.

Later, he said, “Love is the best teacher.”

Why is the sky blue?

In 1910, Einstein asked a question which many children often ask, “Why is the sky blue?”After his careful research, he answered the question like this: “It's because light is made up of many colors including blue. When light travels to Earth, gas particles(气体微粒) spread the blue light all over the sky.”His answer is true in physics.

    Twenty years ago, I drove a taxi for a living. Once at midnight, an old lady in her 80s took my taxi. She gave me an address, and then asked, "Could you drive through downtown?"

    "It's not the shortest way," I answered quickly.

    "Oh, I don't mind," she said. "I'm in no hurry. I'm on my way to a hospice (临终关怀医院）. I don't have any family left. The doctor says I don't have very long time."

    I quietly shut off the meter. "What route would you like me to take?" I asked.

    For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she and her husband had lived, the place where she danced as a girl. As the sun was rising, she asked me to go to the address she had given me.

    "How much do I owe you?" she asked, reaching into her purse.

    "Nothing," I said.

    "You have to make a living," she answered.

    "There are other passengers."

    "You gave an old woman a little moment of joy," she said. "Thank you."

    I drove into the fine morning light. Behind me, a door shut. It was the sound of the closing of a life. I drove aimlessly（漫无目的地），lost in thought. For the rest of that day, I could hardly talk. What if that woman had gotten an angry driver, or one who was impatient to end his shift? What if I had refused to take the run?

    Helen Keller lived in the U.S.A. She was a great woman.

    When Helen was a baby, she got very sick. After many weeks, the doctor said, “She is better, but now she can't see or can't hear.” Her mother and father were very sad.

    After a few years, things got worse. There was no way for Helen to speak with other people. She heard nothing. She saw nothing. She didn't understand anything.

    Then one day a teacher came to live with Helen and her family. The teacher helped Helen learn about words. Helen was a very bright child and soon she learned to spell her first word. When she was older, she went to college(大学).

Helen was very famous. She helped many blind(盲) and deaf(聋) people. She traveled around the world and helped many people.

    Helen was a very old woman when she died. The world remembers her today as a brave and wonderful person. She was blind and deaf, but she found a way to see and hear.

I have a sister and her name is Gina. She is 11 years old. I look like (长得像)my mother and Gina looks like my father. All my family are in the same school. My parents are teachers.

    Angelo Casimiro made something new at the age of fifteen.

    Casimiro made a device(装置）. It can charge（给……充电）your cellphone as you walk! When you run, jump or walk, a pair of discs(唱片）inside the shoes can produce electricity. It can be used to charge your phone or any other devices with a USB port!

    People have to move a lot if they use the device to charge. Those who like travelling in the wild will love it. It takes about eight hours' jogging to charge a lithium-ion（锂离子）battery and two hours' playing basketball will only give the cellphone about 10 minutes' charge.

    A device called SolePower is a kind of insole（鞋垫）that can produce electricity. SolePower is like Casimiro's device, but it can fully charge a cellphone after over a four-kilometre walk. So there's a lot for Casimiro to do to make his invention（发明）better.

    Anyway, Casimiro's device is quite good. After all, his invention started something new, right?

    When I was 17, I read a magazine article about a museum called the McNay, once the home of a watercolorist named Marian McNay. She has requested the community to turn it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, "Do you have the address?'", but I'll recognize it, there was a picture in the magazine."

    "Oh, stop. There it is!"

    The museum was free. We entered, excited. A group of people sitting in the hall stopping talking and stared at us.

    "May I help you?" a man asked. "No," I said. "We're fine." Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? sally had gone upstairs. The people in the hall seemed very nosy (爱窥探的) ,keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. "Where do you think you are?" he asked. I turned sharply. "The McNay Art Museum!" he smiled, shaking his head. "Sorry, the McNay is on New Braunfels Street." "What's this place?" I asked, still confused. "Well, it's our home." My heart jolted (震颤) .I raced to the staircase and called out." Sally! Come down immediately!"

    There's some really good stuff (艺术作品) up there." She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, "Sorry, please forgive us, you have a really nice place "Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.

    The real McNay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.

    Thirty years later, a woman approached me in a public place. "Excuse me, did you ever enter a residence, long ago, thinking it was the McNay Museum?"

    "Yes. But how do you know? We never told anyone."

    "That was my home. I was a teenager sitting in the hall Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you."
