问答题Understanding this transition requires a look at the two-sided connection between energy and human well-being. Energy contributes positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. But the costs of energy--including not only the money and other resources devoted to obtaining and exploiting it, but also environmental and sociopolitical impacts-- detract from well-being. For most of human history, the dominant concerns about energy have centered on the benefit side of the energy-well-being equation. Inadequacy of energy resources or more often of the technologies and organizations for harvesting, converting, and distributing those resources has meant insufficient energy benefits and hence inconvenience, deprivation and constraints on growth. The 1970"s, then, represented a turning point. After decades of constancy or decline in monetary costs--and of relegation of environmental and sociopolitical costs to secondary status--energy was seen to be getting costlier in all respects. It began to be probable that excessive energy costs could pose threats on insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits.

问答题In the past year, a lot has changed in the field of human spaceflight. (46) In January, President George Bush brushed aside the fact that America's entire space-shuttle fleet was grounded when he announced grandiose plans to put people back on the moon, and then to launch a manned mission to Mars. (47) In June, Burt Rutan, an American aeronautical engineer, showed that human spaceflight was no longer the preserve of governments by sending a man to the edge of space in Space Ship One, a privately financed vehicle that cost about the same to build as a luxury yacht. That was followed in September by Sir Richard Branson, the British entrepreneur behind the Virgin brand, announcing that he had signed a deal with Mr Rutan to work on plans for a fleet of five suborbital vehicles developed from Space Ship One. (48) Now, in the dying days of the year, America's Congress has passed a bill that unravels a tangle about who would be responsible for regulating the fledgling industry, and under what terms. (49) The hill also allows passengers to fly on the understanding that this new generation of vehicles may not be as safe as taking a commercial flight between, say, New York and London. The official line from Virgin Galactica, as Sir Richard's latest venture is modestly named, is that this coming change in the law makes no practical difference to the firm's plans, since they do not intend to fly unless they can make their spacecraft as safe as a private jet. But it must surely come as some sort of relief. In any case, Will Whitehorn, director of corporate affairs at Virgin's headquarters in London, and soon to become the president of Virgin Galactica, says that work is under way on a mock up of the inter[or of a new spacecraft that will hold five passengers. (50) Virgin has already committed ＄20m towards licensing the SpaceShipOne technology from Mr Rutan and his financial backer Paul Allen, a software billionaire.

问答题On Leadership What is leadership? Its qualities are difficult to define. But they are not so difficult to identify. Leaders don't force other people to go along with them. They bring them along. Leaders get commitment from others by giving it themselves, by building an environment that encourages creativity, and by operating with honesty and fairness. Good leaders aren't "lone rangers." They recognize that an organization's strategies for success require the combined talents and efforts of many people. Leadership is the catalyst for transforming those talents into results. Leaders know that when there are two opinions on an issue, one is not bound to be wrong. They recognize that hustle and rush are the allies of superficiality. They are open to new ideas, but they explore their ramifications thoroughly. Successful leaders are emotionally and intellectually oriented to the future—not wedded to the past. They have a hunger to take responsibility, to innovate, and to initiate. They are not content with merely taking care of what's already there. They want to move forward to create something new. Leaders provide answers as well as direction, offer strength as well as dedication, and speak from experience as well as understanding of the problems they face and the people they work with. Leaders are flexible rather than dogmatic. They believe in unity rather than conformity. And they strive to achieve agreements out of conflict. Leadership is all about getting people consistently to give their best, helping them to grow to their fullest potential, and motivating them to work toward a common goal. Leaders make the right things happen when they're supposed to. A good leader, an effective leader, is one who has respect. Respect is something you have to have in order to get. A leader who has respect for other people at all levels of an organization, for the work they do, and for their abilities, aspirations and needs, will find that respect is returned. And all concerned will be motivated to work together.

问答题Technology trends may push Silicon Valley back to the future. Carver Mead, a pioneer in integrated circuits and a professor of computer science at the California Institute of Technology, notes there are now work stations that enable engineers to design, test and produce chips right on their desks, much the way as editor creates a newsletter on a Macintosh. As the time and cost of making a chip drop to a few days and a few hundred dollars, engineers may soon be free to let their imagination soar without being penalized by expensive failures. Mead predicts that inventors will be able to perfect powerful customized chips over a weekend at the office — spawning a new generation of garage starts-ups and giving the US a jump on its foreign rivals in getting new products to market fast. "We've got more garages with smart people. " Mead observes, "We really thrive on anarchy. "
