    Look at the map of Spain and point at the center. You've located the country's capital and one of Europe's most beautiful cities: Madrid. This popular destination is considered a city of contrasts with its abundant historic sites, resting in the shadows of modern skyscrapers.

    History

    This city of over 3 million people is proud of Western Europe's largest royal palace, and some consider it to be Madrid's most beautiful building.

    Inside the Royal Palace 2,800 rooms are decorated in glory with museum-quality furniture and artworks. Tourists can tour 50 of these large and splendid rooms.

    Art

    The Internationally respected Prado Museum is the largest and most impressive art gallery in Spain. Opened in 1819, it is filled with works of art that feature the world's most comprehensive collection of Spanish paintings.

    Shopping

    Madrid has some of Europe's best shopping, and potential buyers love to look through the stores looking for bargains. But for 500 years, shoppers have gathered to an extremely large outdoor flea market known as the Rastro where they find everything from antiques to CDs.

    Entertainment

    No trip to Madrid is complete without seeing a performance of Spain's famous art form, flamenco. Every day, flamenco performers sing, dance or play the guitar in small cafes and grand theaters alike.

    Food

    Madrid has a wide variety of restaurants, but because the Spanish typically eat late at about 9 or 10 p.m., it's difficult to find good dinner food earlier. If you get hungry before then, the best solution is to try a tapas bar where light snacks are served. Be sure to try the jamon, a kind of dry-cured ham: Spain is famous for it.

    This is my son Matthew's last night at home before college. I know that this is good news. I feel proud that Matthew will go to a great school. I know that this is finest hour. But looking at the suitcases on his bed sends me out of the room to a hidden corner where I can't stop crying.

    Through the sorrow, I feel a rising embarrassment. "Pull yourself together!" I tell myself. There are parents sending their kids off to battle zones. How dare I feel so shocked and upset?

    One of the great gifts of my life has been having my boys, Matthew and Johnowen. Through them, I have explored the mysterious, complicated bond between fathers and sons. As my wife and I raised them, I have discovered the love and loss between my father and me. After my parents' divorce，I spent weekends with my dad in Ohio. By the time Sunday came around, I was unable to enjoy the day's activities because I was already afraid of the goodbye of the evening.

    Now，standing among Matthew's accumulation of possessions, I realize it's me who has become a boy again. All my sadness and longing to hold on to things are back, sweeping over me as they did when I was a child.

    His bed is tidy and spare. It already has the feel of a guest bed. In my mind I replay wrapping him in his favorite blanket. That was our nightly routine until one evening he said," Daddy, I don't think I need a blanket tonight." I think of all the times we lay among the covers reading. I look at the bed and think of all the recent times I was annoyed at how late he was sleeping. I'll never have to worry about that again, I realize.

    For his part, Matthew has been a rock. He is treating his leaving as just another day at the office. And I'm glad. After all, someone's got to be strong. I'm proud that he is charging into the first chapter of his adult life with such confidence.

    Samuel Osmond is a 19-year-old law student from Cornwall, England. He never studied the piano. However, he can play very difficult musical pieces by musicians such as Chopin and Beethoven just a few minutes after he hears them. He learns a piece of music by listening to it in parts. Then he thinks about the notes(音符) in his head. Two years ago, he played his first piece Moonlight Sonata（奏鸣曲）by Beethoven. He surprised everyone around him.

    Amazed that he remembered this long and difficult piece of music and played it perfectly, his teachers say Samuel is unbelievable. They say his ability is very rare, but Samuel doesn't even realize that what he can do is special. Samuel wanted to become a lawyer as it was the wish of his parents, but music teachers told him he should study music instead. Now, he studies law and music.

Samuel can't understand why everyone is so surprised. "I grew up with music. My mother played the piano and my father played the guitar. About two years ago, I suddenly decided to start playing the piano, without being able to read music and without having any lessons. It comes easily to me —I hear the notes and can bear them in mind—each and every note," says Samuel.

Recently, Samuel performed a piece during a special event at his college. The piece had more than a thousand notes. The audience was impressed by his amazing performance. He is now learning a piece that is so difficult that many professional(专业的) pianists can't play it. Samuel says confidently, "It's all about super memory—I guess I have that gift."

    However, Samuel's ability to remember things doesn't stop with music. His family says that even when he was a young boy, Samuel heard someone read a story, and then he could retell the story word for word.

    Samuel is still only a teenager. He doesn't know what he wants to do in the future. For now, he is just happy to play beautiful music and continue his studies.

    Ten years ago, I set out to examine luck. I wanted to know why some people were always in the right place at the right time, while others consistently experienced ill fortune. I placed advertisements in national newspapers asking for people who felt consistently lucky or unlucky. Hundreds of extraordinary men and women volunteered for my research. Over the years I have interviewed them, monitored their lives and had them take part in various experiments.

    In one of the experiments, I gave both lucky and unlucky people a newspaper, asking them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper, saying, "Tell the experimenter you have seen this and you will win $50." This message took up half of the page and was written in type that was more than two inches high. It was staring everyone in the face, but the unlucky people tended to miss it and the lucky people tended to spot it.

    Unlucky people are generally more nervous than lucky people, and this anxiety affects their ability to notice the unexpected. As a result, they miss opportunities because they are too focused on looking for something else. They go to gatherings concentrating on finding their perfect partners and miss opportunities to make good friends. They look through newspapers determined to find certain types of job advertisements and miss other types of jobs.

    Lucky people are more relaxed and open, and therefore see what is there rather than just what they are looking for. My research eventually showed that lucky people are skilled at noticing opportunities, make lucky decisions by listening to their intuition (直觉), are open to new experiences, and adopt a never-say-die attitude that transforms bad luck into good luck.

    History is full of tales of great ideas taking shape in sleeping minds; Paul McCartney said that he awoke with the tune of Yesterday in his head, and Robert Louis Stevenson said that the idea for The Strange Case of Dr Jekyll and Mr Hyde came to him in a dream.

    Scientists believe that the mind at night puts together bits of information in creative ways. Throughout the day your brain rarely gets a chance to stop and think. It constantly responds to a stream of challenges, from writing a report for a work deadline to remembering where you left your car keys and figuring out what to buy for dinner.

    "Think of your brain like a web," says Russell Foster, Professor of Neuroscience at Oxford University. "During the day the web is very tight, so you can only put information in a certain number of places. During sleep the web expands, and with the luxury of time, those bits of information can be put into lots of different places and make new associations."

    He adds that this process may help to foster the formation of new ideas. "This bringing together of seemingly unrelated bits of information is vital to helping the brain think itself out of problems," says Russell Foster.

    "Sleep seems to allow your mind to make non-obvious connections. It puts all the information from the day into a big biological theatre and forces the mind to speak to people at the back of the theatre, who you may not think you have any connection with. This is the basis of creativity connecting ideas, events and memories that wouldn't normally fit together.

    By placing volunteers into brain scanners and sending them to sleep, scientists have seen that the areas associated with emotion go into overdrive, especially while dreaming, while the areas that are responsible for logic (逻辑)are switched off. This not only explains why dreams are unbelievably random-you can be talking to a colleague one minute and the next minute sitting in your old school classroom dressed in your nightclothes­but also explains how the brain can put together different information.
