单选题Science is a dominant theme in our culture. Since it touches almost facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain of one knows something about the things that excite and frustrate the scientist. This book is written for the intelligent student of lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who has been presented with science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or independently of any course—simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture. We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populated it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not a unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far from being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human equally. We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn"t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime than as a grim and dreary way to earn a living.

单选题The Solar Decathlon is under way, and teams of students from 14 colleges and universities are building solar-powered homes on the National Mall in Washington, D. C. in an effort to promote this alternative energy source. This week judges in this Department of Energy (DOE) sponsored event will evaluate these homes and declare one the winner. Unfortunately, for the participants, it rained on the Sept 26th opening ceremonies, and the skies over the Washington have remained mostly overcast since. However, the conditions may have made for a more revealing demonstration of solar energy than was originally planned. Although the Solar Decathlon"s purpose is to advertise the benefits of electricity-generating solar panels and other residential solar gadgets, the bad weather has made it hard to ignore the limitations. As fate so amply demonstrated, not every day is a sunny day, and indeed DOE"s "Solar Village on the National Mall" has received very little of what it needs to run. Since solar is not an always available energy source, even a community consisting entirely of solar homes and businesses would still need to be connected to a constantly-running power plant (most likely natural gas or coal fired) to provide reliable electricity. For this reason, the fossil fuel savings and environmental benefits of solar are considerably smaller than many proponents suggest. Washington, D. C. gets its share of sunny days as well, but even so, solar equipment provides only a modest amount of energy in relation to its cost. In fact, a $ 5, 000 rooftop photovoltaic system typically generates no more than $100 of electricity per year, providing a rate of return comparable to a passbook savings account. Nor do the costs end when the system is installed, lake anything exposed to the elements, solar equipment is subject to wear and storm damage, and may need ongoing maintenance and repairs. In addition, the materials that turn sunlight into electricity degrade over time. Thus, solar panels will eventually need to be replaced, most likely before the investment has fully paid itself off in the form of reduced utility bills. Solar energy has always had its share of true believers willing to pay extra to feel good about their homes and themselves. But for homeowners who view it as an investment, it is not a good one. The economic realities are rarely acknowledged by the government officials and solar equipment manufacturers involved in the Solar Decathlon and similarly one-sided promotions. By failing to be objective, the pro-solar crowd does consumers a real disservice.

单选题(Despite) much research

单选题Potentially offering a powerful new tool against terrorism, researchers have found a novel way to detect deception: in the liar"s blushing face. The technique, described in the journal, Nature, uses a thermal camera to detect sudden, involuntary shifts of blood flow in the face. The system performed as accurately as a traditional polygraph, the scientists report. Yet the camera can provide answers instantly, and does not require a highly trained specialist to operate it or interpret its results. This makes it far better suited than the polygraph for a new, high-tech approach to security that is already raising the hackles of civil libertarians: the screening of large numbers of citizens, at airports and other sensitive areas, who have done nothing wrong. "The next decade is going to see the development of truly accurate lie detectors," said Stephen M. Kosslyn, an expert on detecting lies and a professor of psychology at Harvard University. The prototype, built by researchers at the Mayo Clinic and Honeywell Laboratories in Minnesota, is at least 2 years from being ready for general use. But other scientists said the discovery of previously unknown physiological changes in the face was itself an important step forward. "This is potentially very important work, which may open a new window on the mind," said Kosslyn. Pushed by technological advances, and with fresh interest, since Sept. 11, the discovery is part of a boom in the scientific study of deceit and its detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new approaches that might replace the polygraph, from brain scans, to subtle changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding, though, is remarkable for its simplicity. When a person tells a lie, the team found, there is a sudden rush of blood to the area around the eyes, according to the Mayo Clinic"s Dr. James A. Levine. Although the change is not: ordinarily visible, the blood warms the skin, causing hands of color to appear through a camera sensitive to heat. The team devised a computer program that can identify the telltale changes based on the camera images. In testing at the US Department of Defense Polygraph Institute, which trains federal polygraph examiners, the device performed better than polygraphs, with 85 percent accuracy compared with 70 percent for the polygraph.
