Throughout the history of the arts, thenature of creativity has remained constant to artists．Nomatter what objects they select, artists are to bring forth new forces andforms that cause change—to find poetry where no one has ever seen orexperienced it before．

Landscape (风景) isanother unchanging element of art．It can be found from ancient timesthrough the17th-century Dutch painters to the 19th-century romanticists andimpressionists．Inthe 1970s Alfred Leslie, one of the new American realists, continued thispractice．Lesliesought out the same place where ThomasCole, a romanticist, had producedpaintings of the same scene a century and a half before．UnlikeCole who insists on a feeling of loneliness and the idea of finding peace innature, Leslie paints what he actually sees．In his paintings, there is no particularchange in emotion, and he includes ordinary things like the highway in thebackground．Healso takes advantage of the latest developments of color photography to helpboth the eye and the memory when he improves his painting back in his workroom．

Besides, all art begs the age-oldquestion: What is real? Each generation of artists has shown theirunderstanding of reality in one form or another．The impressionists saw reality in briefemotional effects, the realists in everyday subjects and in forest scenes, andthe Cro-Magnon cave people in their naturalistic drawings of the animals in theancient forests．Tosum up, understanding reality is a necessary struggle for artists of allperiods．

Over thousands of years the function ofthe arts has remained relatively constant．Past or present, Eastern or Western, thearts are a basic part of our immediate experience．Many and different are the faces ofart,and together they express the basic need and hope of human beings．

    Man has been to the moon. It has been the first step towards future exploration in space. When compared with the distances between Earth and the other planets, the distance between the Moon and Earth is very short indeed. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next step. Such travels will be more challenging than the trip to the moon and certainly more exciting and dangerous. Recently, two American spaceships, Viking 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither been confirmed nor ruled out (排除). Russians have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the Earth's atmosphere. Scientists believe man may find planets which have the same conditions as those we have on Earth, but man should realize Earth will be his only home for a long time and begin to love and care for it.

    Spring is coming, and it is time for those about to graduate to look for jobs. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing, our family and friends may accept us, but the workplace may not.

    A high school newspaper editor said it is unfair for companies to discourage visible tattoos (纹身)，nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do "cover" themselves in order to convey certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.

    Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees, because those people represent the companies to their customers.

    As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can't expect all our customers are.

    There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.

WISH YOU WERE MORE CREATIVE?

    I want to ask you a favor. I have a pair of pants. Tell me: How many different ways can I put a pair of pants to use? Now imagine you're an architect. Same question. Now imagine you're Bill Gates. A scuba diver. A medieval knight. You still have the pants. What alternative uses come to mind?

    What you just practiced--the conscious act of "wearing" another self-is an exercise that, according to psychiatrist SriniPillay, MD, is essential to being creative.

    One great irony (讽刺) about our collective addiction to creativity is that we tend to frame it in uncreative ways. That is to say, most of us marry creativity to our concept of self: Either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a discouraged student might say in art class, while another might blame her talent at painting for her difficulties in math, making a comment "I'm very right-brained."

    Dr.Pillay, an assistant professor at Harvard University, has spent years overturning these ideas. He believes that the key to unlocking your creative potential is to challenge the stereotyped (陈词滥调的) advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.

    He points to a study showing the impact of stereotype on one's behavior. The authors, psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into two groups, instructing one group to think of themselves as "eccentric poets" and the other to imagine they were "rigid librarians". The researchers then presented them all with ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. The former group came up with the widest range of ideas, whereas the latter had the fewest.

    These results suggest that creativity is not an individual characteristic but a "product of context and perspective". Everyone can be creative, as long as he or she feels like a creative person.

    Dr. Pillay's work takes this a step further: He argues that simply identifying yourself as creative is less powerful than taking the brave, creative step of imagining you are somebody else. This exercise, which he calls psychological Halloweenism, refers to the conscious action of "wearing" another self. An actor may employ this technique to get into character, but anyone can use it. According to Dr. Pillay, it works because it is an act of conscious unfocus, a collection of brain regions that spring into action when you're not focused on a specific task or thought. Most people spend nearly half of their days in a state of "unfocus." This doesn't make us lazy; it makes us human.

    Imagining yourself in a new situation, or an entirely new identity, never felt so productive. You're making yourself more creative, and you're giving yourself permission to do something you'd otherwise feel guilty about.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically, it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."
