We can achieve knowledge either actively or passively. We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.

    We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Conditioned as we are to passive learning, it's not surprising that we depend on it in our everyday communication with friends and co-workers.

    Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay (传闻) and rumor.

    Did you ever play the game Rumor? It begins when one person writes down a message but doesn't show it to anyone. Then the person whispers it, word for word, to another person. Thai person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements arc compared. Typically, the original message has changed.

    That's what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a story, trying to improve on it, stamping it with their own personal style. Yet those who hear it think they know.

    This process is also found among scholars and authors: A statement of opinion by one writer may be restated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.

    The values of artistic works, according to cultural relativism（相对主义）, are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

    History has witnessed the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries. Unique works of this kinds are different from today's popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

    In a 1757 essay, the philosopher David Hume argued that because “the general principles of taste are uniform（不变的）in human nature,” the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

    Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    Generally speaking, people like those who have a good sense of humor.

    Sometimes a touch of humor might well enable us to win. Consider the case of a young friend of mine, who hit a traffic jam on his way to work shortly after receiving an ultimatum (最后通牒) about being late on the job. Although there was a good reason for Brian's being late—serious illness at home—he decided that this by-now-familiar excuse wouldn't work any longer. His boss was probably already pacing up and down preparing a dismissal speech.

    Yes, the boss was, as Brian entered the office at 9:35. The place was as quiet as a locker room (更衣室): everyone was hard at work. Brian's boss came up to him. Suddenly, Brian forced a smile and stretched out his hand. "How do you do!" he said. "I'm Brian. I'm applying for a job, which, I understand, became available just 35 minutes ago. Doesn't the early bird get the worm?"

    The room exploded in laughter. The boss clamped off a smile and walked back to his office. Brian had saved his job, with the only tool that could win—a laugh.

    Humor is a most effective, yet frequently neglected means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying "no", criticizing, getting the other fellow to do what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialog may start a quarrel. For example, many believe that comedians on television are doing more today for racial and religious tolerance (忍受力) than people in any other forum.

    I remember little of the journey which started so early in the morning. I only know that the day seemed extremely long, and that we appeared to travel over hundreds of miles. Calmed by the sound of the coach wheels, I fell asleep. But I had not slept long when the coach stopped, the door was opened, and I saw a servant standing there.

    "Is there a little girl called Jane Eyre here?" she asked. I answered "Yes," and was then lifted out. My trunk handed down, the coach instantly drove away. I looked about me. I could see a house with many windows. There were lights burning in some of them. We went up a wide pebbly path, splashing wet, and were admitted at a door. Then the servant led me through a passage into a room where she left me. I stood and warmed my frozen fingers at the fire and looked around. There was no candle, but the light from the fire showed papered walls, a carpet, curtains and gleaming furniture. Then the door opened, and a tall lady with dark hair, dark eyes entered followed by another who looked younger. "The child is very young to be sent alone," said she, putting her candle down on the table. She looked at me for a minute or two and then added, "She had better go to bed soon; she looks tired."

    Led by the younger lady, Miss Miller, through passage after passage, we came, at last, to a long, wide room filled with the hum of many voices. There were many tables, and seated all round on benches were a large number of girls aged from nine to twenty. Seen in the dim light of the candles, their number appeared above eighty. Each was dressed in a brown old-fashioned dress of cheap material. It was their hour of study.

    Miss Miller signed to me to sit on a bench near the door, then walking up to the top of the long room she cried out "Monitors, collect the lesson-books and put them away!"

    Four tall girls arose and went round, gathered the books and removed them. Miss Miller again ordered, "Monitors, fetch the supper-trays!" The tall girls went out and returned presently, each bearing a tray. Some food and water was in the middle of each tray. The food was handed round and everyone drank from the same mug. When it came to my turn, I drank too, for I was thirsty, but I did not touch the food. From there I was taken to my hard bed where I thankfully fell asleep immediately.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.
