How Room Designs Affect Our Work and Feelings

    Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical(经验的，实证的) basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.

    Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.

    In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.

    Using nature to improve focus of attention ought to pay off academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.

    Recent study on room lighting design suggests than dim(暗淡的) light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.

    So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw(吸管)," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."

    One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the art works.

    A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided the wife was doing all the talking. I admired his patience for putting up with her continuous talk. Distracted by their noise, I moved on.

    I met with them several times as I moved through the different rooms of art. Each time I heard her constant burst of words, I moved away quickly.

    I was standing at the counter of the museum gift shop making a purchase when the couple came near to the exit. Before they left, the man reached into his pocket and pulled out a white object. He extended it into a long stick and then tapped his way into the coatroom to get his wife's jacket.

    "He's a brave man.," the clerk at the counter said, "Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise that his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show."

    "But what does he get out of the art?" I asked. "He can't see."

    "Can't see? You're wrong. He sees a lot. More than you or I do," the clerk said. "His wife describes each painting so he can see it in his head."

    I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life. And I saw the love shared by two people as I watched this couple walk away.

The Trip to Alishan in Taiwan

    It was the fourth day of our trip to Taiwan, bright but cold. After a good breakfast we put on our jackets and gloves, pulled on our hats and got into a car. We travelled for about two hours, up, and up, and up the mountain road.

    We finally arrived at the top of the mountain. It was Christmas Day. So imagine my joy to see icicles(冰柱)hanging form branches and the whiteness of the scenery. Indeed, it was my first Christmas in the northern hemisphere(半球)and, guess what? It even started snowing too. How amazingly exciting for me to have Christmas in my grandmother's hometown, and to experience icicles and snow. Alishan is really beautiful, especially seen form this dizzy height. After Sun parked the car, we got out and looked down through the trees. It hadn't snowed hard enough so there was no snow on the ground, just loads of pine needles. There was a most wonderful smell of pine sap(松液)drifting up to us form the ground. It was very quiet, except for the twittering of birds, and the odd car passing along the road. Quietness in Taiwan is something to treasure.

    Over the road was a small stall so we went over to it. They were selling some drink steaming hot in paper cups, too hot to hold immediately. We jumped around to get warm. There was a cool wind blowing up the side of the mountain, and the clouds above us were moving along quickly. I could imagine there was quite a strong wind blowing up there, so I was glad we were down on the ground! The drink cooled down fairly rapidly. I picked up my share and, wow, what a lovely smell was coming from it. It was the smell of ginger(姜).I took a sip. How delicious, and so this was ginger tea, which I had never tried before. It warmed my body so quickly that I could feel the heat travel right down to my fingers and to my toes. This was very good stuff. And then it was time to leave as we were going down to Hualian to attend a Buddha bi-bi, eat hot pot, and drink some Shaoxing rice wine.

    Three men have had a big influence on modern sound and communication technologies. We started with the beginnings of computer-generated music.

Max Vernon Mathews

    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 wrote the first: computer program, Music, to enable a computer to create sound and play it back. 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.

    Mathews continued creating other versions of the Music program. He became interested in how computers could help musicians outside recording studios. The Groove program he developed was the first computer program made for live performances.

Norio Ohga

    Sony Corporation official Norio Ohga helped to develop, the compact disc in the late 1970s.

    He pushed for CDs to be larger, and with a longer playing time. He wanted them to hold seventy-five minutes so that they could store all of Bcethoven's Ninth Symphony on one disc. This way, listeners could enjoy the musical work without any break. The compact disc changed the electronics industry and the way people listened to music.

Hubert Joseph Schlafly

    Hubert Joseph Schlafly was an electrical engineer who helped change the way actors, politicians and other people speak on television. In 1950, he and two other men developed the teleprompter. One co-worker, Fred Barton, was an actor. He had an idea for a tool that would help television actors read their lines without having to memorize them. The first teleprompter involved a person who turned a long piece of paper printed with tall letters. As the actor read the lines, another person would, move the paper ahead on the device. Later versions used television screens to show the words that were to be read.

    Many studies have hinted(暗示) that alcohol, in moderation, can do a heart good. But new research suggests that moderate drinkers are no more likely than non­drinkers to have clear arteries(动脉).

    The scientists looked at almost 2,000 patients who underwent CT test. Overall, there was no association between people's drinking habits and their heart diseases. Researchers said an advantage of the new study is that it used objective measurements.

    “No prior studies have assessed the relationship between alcohol consumption and the presence of heart disease,” said lead researcher Dr Julia Karady. "We could not find any relation between the presence of heart disease and alcohol consumption," Karady said. At the same time, she added, there was no evidence that heavier drinking raised the risk of heart disease.

    However, groups like the American Heart Association(AHA) warn against excessive drinking, because it can raise blood pressure and contribute to heart failure and other problems.

    In general, "moderate" is defined as no more than one glass of alcohol a day for women, and no more than two a day for men. But those studies do not prove that alcohol, itself, protects the heart—in large part because alcohol also carries risks.
