An elderly carpenter was ready to retire. He told his employer of his plans to leave the house building business and live a more leisurely life with his wife, enjoying his extended family. He would miss the pay check, but he needed to retire.

    The employer was sorry to see his good worker go and asked if he could build just one more house as a personal favor. The carpenter said yes, but in time it was easy to see that his heart was not in his work. He used shoddy materials to build the house. It was an unfortunate way to end his career.

    When the carpenter finished his work and the employer came to inspect the house, he handed the front-door key to the carpenter. “This is your house,” he said, “my gift to you.”

    What a shock! What a shame! If he had only known he was building his own house, he would have done it all so differently. Now he had to live in a home he hadn't built very well.

    It is the same with us. We build our lives in a distracted way, reacting rather than acting, willing to put up with less than the best. At important points, we don't give the job our best effort. Then with a shock we look at the situation we have created and find that we are now living in the house we have built. If we had realized that, we would have done it differently.

    Think of yourself as the carpenter. Think about your house. Each day you hammer a nail, place a board, or erect a wall, build wisely. It is the only life you ever build. Even if you live it for only one day more, that day deserves to be lived graciously and with dignity. The plague (牌匾) on the wall says, “Life is a do-it-yourself project.”

    Who could say it more clearly? Your life today is the result of your attitudes and choices in the past. Your life tomorrow will be the result of your attitudes and the choices you make today.

    Mary went out at night. She never forgot the night when she met a robber many years ago. That evening, she was invited to a birthday party which lasted until two o'clock in the morning. Without company Mary walked along the quiet street.

    Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. "Good evening, lady," the man said in a low voice, "I don't think you wish to die here."

    "What do you want?" Mary asked.

    "Your earrings（耳环）. Take them off!"Slowly Mary's eyes looked down. She tried to cover her necklace with the collar（领子）of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground.

    "Take them and let me go." She said. The robber looked at her only feeling uncertain. He saw the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, "Give me your necklace."

    "Oh, sir. It's not worth much. Please let me keep it."

    "Stop rubbish. Quick!"

    With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends.

    The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings.

    You've got your fancy new suitcase and you're ready to take it with you on your travels across the globe.

    You get to the airport, quickly moving through the crowds on the uneven pavement, rushing to check in. Then, your heart sinks when you realize your new suitcase has got a serious case of the wobbles (摇晃).

    Why does this happen?

    Scientists from the Universite Paris-Diderot in France investigated this matter and published their findings in the science journal Proceedings of the Royal Society A. They also suggested some solutions to overcome this modern-day problem.

    To learn more about the issue, they put a suitcase on a treadmill (跑步机) and observed what happened.

    It was soon noted that the "wobble" was actually a result of repeated actions that caused the suitcase to sway from side to side. They discovered that if one of the wheels encountered an obstacle such as a small bump, it jumped into the air for just a moment and then banged back down to the ground. That second action caused the opposite wheel to lift off the ground and then to bang back down, causing the first to lift again and so on. This swaying increased as the luggage was pulled along.

    "The suitcase is a fun way to tackle the problem, but the study would be the same for any trolley with two wheels or blades (桨叶)," Sylvain Courrech du Pont, lead author of the study, told BBC News. "So it will be the same for a caravan (大篷车) or maybe also for airplanes."

    Instead of slowing down when we see a rocky part of the path, the scientists recommended doing the exact opposite and speeding up. This is because going faster gives the wheels less time to rise and fall, preventing the case from swaying. They also said that reducing the angle of the suitcase by lowering its handle to the ground would help keep it steady.

    "These findings could help researchers simulate and design better rolling suitcases and other pulled trolleys, such as towed trailers," Courrech du Pont added.

With these masterminds (智者) working on perfecting our suitcase problems, wobbly luggage may soon be a thing of history, leaving us to enjoy our travels.

    Charles Dickens' joy at first arriving in Boston Harbor in 1842 reads like Ebenezer Scrooge's awakening on Christmas morning. Biographer Peter Ackroyd reports that he flew up the steps of the Tremont House Hotel, sprang into the hall and greeted a curious crowd with a bright "Here we are!" He took to the streets that twinkling midnight in his shaggy fur coat, shouting out the names on shop signs, pulling bell-handles of doors as he passed—excited with laughter—and even screamed with (one imagines) astonishment and delight at the sight of the old South Church. He had set at last upon the shores of "the Republic of my imagination."

    Though not quite 30, Dickens was a literary rock star, the most famous writer in the world, who landed like a conquering hero in a country swept up in an extreme "Boz-o-mania". He wrote to his best friend, John Forster, that he didn't know how to describe "the crowds that pour in and out the whole day; of the people that line the streets when I went out; of the cheering when I went to the theatre; letters of congratulations, welcomes of all kinds, balls, dinners, assemblies without end." When Bostonians renamed their city "Boz-town", New Yorkers determined to "outdollar…and outshine them". Their great Boz Ball boasted flags, flowers, a huge portrait of the author with a bald eagle overhead, 22 tableaux (场景) from the great author's works. "If I should live to grow old," Dickens said, "the scenes of this and other evenings will shine as brightly to my dull eyes 50 years hence as now." ①

    The Spirit of the Times wrote of it: "This most extraordinary, fashionable, brilliant, unique, eye-dazzling, heart-delighting, superb, foolish and ridiculous celebration…came off at the Park Theatre, New York, on Monday evening." But, the reporter predicted, "Such were silly-minded Americans, and such the ridiculous respect paid to a foreigner, who will probably return home and write a book abusing the whole nation for the excesses of a few fools." ②

    In fact, Dickens wrote two.

    ③ Apart from the country's great writers, he found Americans ill-mannered and invading his privacy. "I am so surrounded by people that I am exhausted from want of air." Dickens complained to Forster. "I go to church for quiet, and there is a violent rush to the neighborhood of the bench I sit in. I take my seat in a railroad car, and the very conductor won't leave me alone. I can't drink a glass of water without having a hundred people looking down my throat."

    ④ He disliked Americans' table manners and the tobacco spit everywhere he looked—on even the sidewalks of the nation's capital, where he found party politics corrupting everything, its leaders "the lice (虱子) of God's creation," and "despicable (卑鄙的) trickery at elections."

    Even worse, everyone wanted a piece of the action, from Tiffany's selling unauthorized copies of his bust (半身像) , to a barber selling locks of his hair. "I never knew what it was to feel disgust and contempt (蔑视)," Dickens said, "till I traveled in America." When he departed in June, he left behind all notions of an Arcadian realm he now regarded as "a vast counting house" full of nothing but "cheaters and bores." (See: A Christmas Carol.)

    Americans had soured on him, too. Dickens never missed an opportunity to accuse American publishers of openly pirating his novels to sell for mere pennies, with no recompense to the author at all. The press took offense. Within a month of his arrival, Dickens were laughed at for his "foppish" clothing and effeminate hair, described as "no gentleman," "a contemptible Cockney (伦敦佬)."

    Samuel Morse was born in Massachusetts USA. He started off his career as an inventor after being a painter and sculptor (雕塑家). He even earned a gold medal from the famous Adelphi Society of Arts for his first effort in sculpture, the "Dying Hercules". He became the first president of the National Academy of Design, and was made Professor of the Arts of Design in the University of the City of New York.

    Yet, this painter turned to inventing to make his fortune during a sea voyage. On this journey, Samuel Morse heard about many attempts to create usable telegraphs. He was fascinated by this problem and began to study books on physics for two years to gain more scientific knowledge. He realized that pulses (脉冲) of electrical current could carry information over wires.

    Thus the world's first working model of a telegraph was born. His signaling device was quite simple. It consisted of a transmitter (containing a battery and a key), a small buzzer (蜂鸣器) as a receiver and a pair of wires connecting the two. Samuel Morse improved it by adding a switch and a second buzzer to allow transmission (传播) in the opposite direction as well.

    On May 24, 1844 Samuel Morse sent the first electronic message between Baltimore and Washington, "Look what God has enabled us to build, and benefit by."

    Seventeen years later, the two coasts of the United States were linked by telegraph. The telegraph continued to enjoy the position of being the fastest and most reliable means of communication for almost 140 years since its invention.

    Imagine a school where self-awareness is celebrated, students are encouraged to solve maths problems by writing on the walls and applying learned lessons to real life is more important than homework. These are a few of the concepts that makes Space of Mind School unique.

    Located in a home built in 1896 in Florida, US, the program serves students in grades 2 through 12 and will accept kindergarten students next year. It also offers an after-school program for students who attend traditional schools, as well as evening programs for adults and educators and weekend events for families.

    There is a different atmosphere from that of a traditional school building. Tables and brightly colored walls are white boards. In the science room, students are studying climate changes at a weather station, while in the music room, a student is solving an equation (等式) with his academic coach while he connects music theory and maths.

    The daily schedule at the school also stands out. "We don't assign boring or exhausting homework." said Space of Mind founder and CEO Ali Kaufman. "Instead of homework, we ask that they go home and take a video of themselves applying a lesson they learned or cooking a meal for their family that they learned how to make at school."

    For lunch, instead of traditional cafeteria dishes such as pizza, the school offers organic meals made out of products from local gardens and farms. "Our students also run a business at the Delray Beach Green Market on Saturdays so they can understand sustainable living practices and how to run a business," Kafman said.

    " We are also the first school program in Florida to start and end each day with 15 minutes of meditation (冥想)," Kaufman said. "The positive results we have been seeing in the students from meditation are amazing. We are really about infusing social, emotional and creative skills with academic and life skills."
