Max Vernon Mathews has been called the father of computer music. He created electronic tools so that people could use computers as musical instruments. He had a huge influence on the development of electronic music and how it is written, recorded and played.

    In 1957, Max Mathews wrote the first computer program that enabled a computer to create sound and play it back. At the time, he was working as an engineer at Bell Laboratories in New Jersey. His computer program was called Music. It enabled a large IBM computer to play a seventeen-second piece of music that he had written.

    The computer was so slow that it would have taken an hour to play the piece of music in seventeen seconds. For that reason, Mathews moved the work to a tape player, which could be sped up to play the music at a normal speed. He later said that the sound quality of the music notes was not great, but the technical importance of the music was huge.

    The science fiction writer Arthur C. Clarke visited Bell Laboratories in the 1960s. He heard a computer “sing” the song "Daisy Bell" on devices and programs developed by Max Mathews andother engineers. Clarke noted this technology in his book “2001: A Space Odyssey,” which was later made into a movie.

    Mathews continued creating other versions of the Music program. He became interested in how computers could help musicians outside recording studios.

    Max Mathews had a long and productive career. He worked with composers like John Cage and Edgard Varese. He helped create a center for research in computer music in Paris. And he taught at the Center for Computer Research in Music and Acoustics in Stanford University in California.

    Mathews believed modern musicians were not making full use of the power of computer music. He said a violin always sounds like a violin, but with a computer, the way a violin sounds is unlimited. He said he did not want computer sounds to replace live music. But he said he hoped laptop computers would one day be considered serious instruments

    Why can some people sleep through noises like a honking car or flushing toilet, while others are awakened by the lightest sound?

    To find the answer, sleep researchers at Massachusetts General Hospital conducted an unusual study of 12 self-described deep sleepers. After tests confirmed that the healthy volunteers were solid sleepers, they took part in a three-night study in the university's sleep laboratory. The participants spent the night in a big and comfortable room. But the room also included four speakers positioned near the top of the bed.

    During the night, the deep sleepers were subjected to 14 different recorded sounds, like street traffic, toilets flushing, and an airplane flying overhead. Next door, the researchers monitored their sleep patterns and brain waves.

    As expected, all of the participants slept relatively well, but there were differences in how they responded to the noisy interruptions. Some of the sleepers didn't wake up even when a sound was blasted at 70 decibels（分贝）; others were awakened by sounds at 40 or 50 decibels.

    The researchers discovered that the difference in a sleeper's reaction to noise could be predicted by the level of brain activity called "sleep spindles（纺锤体）". A sleep spindle is a burst of high-frequency brain activity coming from deep inside the brain during sleep. The source of the spindles is the thalamus（丘脑）, a part of the brain that sends sensory information to the rest of the cortex（皮层）.

    Before the study, the Massachusetts researchers theorized that the spindles are the brain's way of preventing sensory information from passing through the thalamus and waking the rest of the brain during sleep. They found that sleepers who experienced the most sleep spindles during the night were also the soundest sleepers and were least likely to be awakened by noise.

    Scientists already know that most people become lighter sleepers with age, most likely because older people experience less "slow wave sleep", which is the deepest stage of sleep. People also produce fewer sleep spindles as they age. But even when controlling for the stage of sleep a person was in, the number of sleep spindles still predicted their risk for awakening because of noise.

    More research is needed, but the findings suggest that a better understanding of sleep spindles could lead to new behavioral or drug therapies for people with sleep disorders. For example, future studies may try to determine whether diet, exercise or other behaviors may influence the number of sleep spindles a person produces during the night.

    Do you love Beats headphones, True Religion jeans, and UGG shoes? These are some of the most popular brands(品牌) around. They are also expensive. But some experts say they are not much better than cheaper brands.

    For example, Jim Wilcox works for Consumer Reports. He tested all kinds of headphones. He says that $80 Koss Pro headphones provide basically the same quality and comfort as Beats. So why do people pay twice or even 10 times as much for the hottest brands?

    Experts say because it's fashionable, and expensive brands send a message. Brands say "I belong" or "I can afford it."

    Some people think that expensive brand names are worth the price. They say that some designer clothes are really of top quality and that they last longer than cheaper brands. Some teenagers choose to wear popular brands because these brands make them feel good about themselves.

    Alexandra Allam, 17, likes to buy brand-name products. "I'd rather spend the extra money getting something I know I'll be satisfied with." she says. Her friend Emmy Swan agrees, saying "As long as you can afford it, it seems reasonable to buy what you want." But not all teenagers agree. "Spending hundreds of dollars for designer is stupid and unreasonable," says Daniel Steinbrecher, 16. "It's fake（假的）happiness."

    People who are against wearing expensive brand names say that many designer brands aren't any better. "It's wasteful to buy things just because they are popular." says Edmund Williams, 15. "You'll feel better if you buy things because you like them. If you have extra money to spend, it would be better to give it to people in need."

    You must have heard of Mr. No Ears. This earless, one-eyed cat from Albufeira, Portugal, is a Facebook phenomenon and has his own book: Saudades Mr. No Ears. But for those of you who don't know him, here is his story.

    Often referred to as the “Lion King of Albufeira”, this adorable cat was the head of a eat colony in the region. Viewed from a distance, he appeared to be a king, sitting on a wall. On most days, this was usually where you would find Mr. No Ears, with the members of his colony scattered around on the walkway. At other times, he was jumping cliffs and running on the beach. No one knew on which day he was born, so his caretakers decided to celebrate his birthday on World Animal Day on October 4th.

    Although there were no ears, his hearing functioned well. One of his eyes was open and purulent (有脓的), with no sign of an eyeball…...Despite all of his problems, he was a strong-minded and happy cat. Some hotel owners found him annoying, ordering his caretakers to send him away so he wouldn't “upset tourists.” But there were just as many people who loved him to pieces, and once he got his own Facebook page, the entire world was at his paws.

    On the evening of 11 September 2015, Mr. No Ears was taken away against his will. Less than an hour later a request was made via a Facebook page asking for money, making false claims that he was “in pain” and “had bone cancer.” It was said that in an attempt to prove cancer which he did not have, Mr. No Ears suffered a heart attack. He then suffered organ damage, including his kidneys and liver. The taking-away of this much-loved cat from his home and family and the circumstances of his death were very emotive subjects, causing shockwaves throughout the animal-loving world.

    Thanks to Mr. No Ears, the Albufeirafs Peneco beach Colony became a household name and a “must see” on cat lovers, holiday choices. You will recognize Mr. No Ears' favorite seat under a palm tree because Mr. No Ears' love-lock is attached to it.

    In a career that lasted more than half a century, Tom Wolfe wrote fiction and nonfiction best-sellers including The Electric Kool-Aid Acid Test and The Bonfire of the Vanities. Along the way, he created a new type of journalism and coined phrases that became part of the American vocabulary.

    Wolfe began working as a newspaper reporter, first for The Washington Post, then the New York Herald Tribune. He developed a literary style in nonfiction that became known as the "New Journalism." "I've always agreed on a theoretical level that the techniques for fiction and nonfiction are interchangeable," he said. "The things that work in nonfiction would work in fiction, and vice versa."

    "When Tom Wolfe's voice broke into the world of nonfiction, it was a time when a lot of writers, and a lot of artists in general, were turning inwards," says Lev Grossman, book critic for Time magazine. "Wolfe didn't do that. Wolfe turned outwards. He was a guy who was interested in other people." Wolfe was interested in how they thought, how they did things and how the things they did affected the world around them.

    In 1979, Wolfe published The Right Stuff, an account of the military test pilots who became America's first astronauts. Four years later, the book was adapted as a feature film. "The Right Stuff was the book for me," says Grossman. "It reminded me, in case I'd forgotten, that the world is an incredible place."

    In The Right Stuff, Wolfe popularized the phrase "pushing the envelope." In a New York magazine article, Wolfe described the 1970s as "The 'Me' Decade." Grossman says these phrases became part of the American idiom because they were accurate.

    "He was an enormously forceful observer, and he was not afraid of making strong claims about what was happening in reality," Grossman says. "He did it well and people heard him. And they repeated what he said because he was right." All those words started a revolution in nonfiction that is still going on.

In Hollywood, few actors have experienced a career as diverse and prolific as Harrison Ford. From the fearless Indiana Jones to the charming Han Sol o and the world-weary Rick Deckard, Ford's portrayal（饰演） of iconic characters has left a permanent mark on cinema and pop culture. Yet, the irony lies in how many of his career-defining roles fell into this "late bloomer's" lap by chance.

Born in Chicago, Harrison was discouraged from pursuing a career on the silver screen early on, having failed to land any significant parts. Instead, he turned to professional carpentry（木工） as a means to keep his family fed.

But fate had other plans. While working as a carpenter in Hollywood, Ford crossed paths with numerous celebrity clients such as Joan Didion and, most notably, director George Lucas, who hired him to build cabinets for his office. Little did Ford know that this chance encounter would lead to his breakthrough role as the charming Han Solo in Star Wars. Lucas was impressed by Ford's presence and offered him the iconic role. In time, Ford rose to a star.

Ford's next lucky moment came when he tried out for the role of Indiana Jones in a massive project by Lucas and Steven Spielberg, Raiders of the Lost Ark. Spielberg initially wanted Ford for the role, but Lucas was hesitant as he had already worked with Ford on Star War and 1973'sAmerican Graffiti. Then the production team tried many other possibilities but without luck. Eventually, the role went to Ford, strengthening his status as a Hollywood legend.

The film series became a worldwide sensation, stimulating people's imagination and inspiring a generation of future archaeologists. Over 40 years and four films later, Ford found himself completing the series with the fifth and final installment. Eighty-one-year-old Harrison received a five-minute standing ovation（鼓掌） at the Cannes Film Festival Premiere and picked up an honorary Palmed' Or for his achievements.

Ford's commitment to his career is evident as he said, "I love the work! My luck has been to work with incredibly talented people, to find my way into this crowd of geniuses." Despite his legendary status in Hollywood, Ford's humility shines through.
