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.

Pablo Picasso was born in Spain in 1881. His father was a painter and art teacher who gave his son the first lesson in drawing. He won a prize — “Science and Charity” for his first important painting when he was only fifteen. He studied in several cities in Spain. But there was no one to teach him all that he wanted to know. When he was nineteen, he visited Paris.

Paris was then the center of the world for artists. Everything that was new and exciting in the world of paintings seemed to happen there. When he was twenty-three, Picasso moved there to live and lived in France for the rest of his life.

    When he was over ninety, this great painter still lived his life like a young man. He was still looking for new ideas and new ways to use his artistic materials.

    When he died in 1973, he was ninety-one years old.

    Last Sunday evening, my parents went out for a walk with my sister. But I studied alone at home because l would have an English test. Suddenly, I saw bright light in my neighbor's kitchen. I thought he was cooking, so I went on studying.  

Soon, there was a terrible smell in the air and I thought something was wrong. I went out and saw fire coming out of my neighbor's kitchen. So I shouted “Fire, Fire!” But no one heard or came out.

    I ran quickly to my house to call 119, and then I rang my neighbor's doorbell, knocked at the door, but there was no response. I got into the house through the window and found my neighbor sleeping in his bedroom. I woke him up and we rushed out of the house together.

    We tried our best to pour water through the kitchen window, but the fire was too heavy. Luckily, the firemen came and put out the fire quickly. When my parents came back, they found I was dirty and tired. After my neighbor told them the whole story, they were happy and said I was a brave boy.

Blue Lightning

    Sally loved cars more than anything else. This spring she thought of building a go-kart to enter for the Go-Go Race. So she asked her dad for help.

    "Well," he said. "How about this: you do some research first and then come back to me with a design."

    A week later, Sally brought her notes and drawings to Dad. She named her go-kart "Blue Lightning". Dad looked over her work, thinking. "Well, that's interesting," he said. "Have a try. Just build Blue Lightning as you've designed."

    Over three weekends of hard work, Sally turned her design into a real, working go-kart and painted it light blue. Dad asked her to take it for a test drive. Sally agreed.

    After she did that, Sally drove back to Dad. "Well," she said. "Now I know why you wanted me to have a test drive."

    "Oh, do you?" he said. "Please share."

    "When I drove fast, there was a lot of pushback," she said. "I think it's because of the lightning bolt (闪电) shape."

    "Very good!" Dad said.

    "So, why didn't you tell me about that problem in the first place?" Sally asked.

    Dad laughed. "Where's the fun in that? If you give a man a fish, he'll eat for a day. But if you teach a man to fish, he'll eat for a lifetime."

    Sally said, "I see. Anyway, designing is half the fun!"

    Dad smiled. "Good. Sometimes, learning happens during the process. We learn how to do something right by doing it a few times first and making mistakes along the way."

    That encouraged Sally and she worked even harder. When she showed Dad her new go-kart, he nodded with pride.

    Finally came the race. Sally wasn't worried about whether she would win—in her mind, she had already won, by building something better than ever before.
