单选题Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place? Why didn't they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets. How many men would have considered the possibility of an apple falling up into the tree? Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don't have unpredictable things, you don't have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it. In talking to some scientists, particularly younger ones, you might gather the impression that they find the "scientific method" — a substitute for imaginative thought. I've attended research conferences where a scientist has been asked what he thinks about the advisability of continuing a certain experiment. The scientist has frowned, looked at the graphs, and said "the data are still inconclusive." "We know that," the men from the budget office have said, "but what do you think? Is it worthwhile going on? What do you think we might expect?" The scientist has been shocked at having even been asked to speculate. What this amounts to, of course, is that the scientist has become the victim of his own writings. He has put forward unquestioned claims so consistently that he not only believes them himself, but has convinced industrial and business management that they are true. If experiments are planned and carried out according to plan as faithfully as the reports in the science journals indicate, then it is perfectly logical for management to expect research to produce results measurable in dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they are going and how they will get there should not be distracted by the necessity of keeping one eye on the cash register while the other eye is on the microscope. Nor, if regularity and conformity to a standard pattern are as desirable to the scientist as the writing of his papers would appear to reflect, is management to be blamed for discriminating against the "odd balls" among researchers in favor of more conventional thinkers who "work well with the team".

单选题 Most critical plot points in Harry Potter and the Sorcerer's Stone came from J. K.Rowling's imagination, but Flamel and his powerful pebble were legendary long before Harry went to Hogwarts. The 14th century alchemist created the philosoper's stone(called "sorcerer's " in U.S. editions of Potter ), with which he turned mercury to gold and gained eternal life. But Flamel's tale—like his stone and his science was no more real than a magic. The philosopher's stone was the key to alchemy, the medieval predecessor to chemistry that aimed to cure all illnesses, make the elixir of life, and transmute base metals into gold. The last made perfect sense at the time. The Aristotelian theory of elements stated that all things consisted of fire, air, water, and earth. So a little shift in one metal's composition could create gold. Flamel was renowned as an alchemical success. In 1382 , after 25 years of studying an ancient book by "Abraham the Jew", he is said to have produced the philosopher's stone.His texts, notably a deconstruction of the "Abraham" work, were standard reading for as-piring scientists like Isaac Newton. Many alchemists believed Flamel faked his 1418 death and that of his wife. Rumored sightings in the 18th century placed them at the Paris Opera. As late as 1816 there were reports of people searching Flamel's former house for secrets of the stone. Contemporary historians say a Nicolas Flamel did live in Paris in the 1300s and endowed many churches and hospitals with his wealth! But he was not alchemist. "He go this money in pedestrian ways—his wife's earlier marriages, real-estate speculation", says Lawrence Principe, author of The Aspiring Adept. Anachronisms, style of language, and the lack of earlier copies indicate that none of "his " writings originated prior to the 1500s. "This sort of thing happens in alchemy", says Bill Newman, author of alchemical history Gehennical Five. When an alchemist couldn't back up his ideas, he might publish them in the guise of a "lost" work. Flamel's wealth made a good candidate for alchemical identity theft. Flamel's writings and sightings faded with alchemy's prestige. And the closest anyone's come to the philosopher's stone is Rowling. In her hands, it has yielded not just gold but eternal (shelf) life as well.

单选题The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihoods of success, making a decision, and only then taking action to implement the decision. Rather, in their day-by-day tactical maneuvers, these senior executives rely on what is vaguely termed "intuition" to manage a network of interrelated problems that require them to deal with ambiguity, inconsistency, novelty, and surprise; and to integrate action into the process of thinking. Generations of writers on management have recognized that some practicing managers rely heavily on intuition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse for capriciousness. Isenberg's recent research on the cognitive processes of senior managers reveals that managers' intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform well-learned behavior patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and hands-on experience that build skills. A third function of intuition is to synthesize isolated bits of data and practice into an integrated picture, often in an "Aha!" experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally leery of solutions suggested by these methods which run counter to(违反, 背道而驰)their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to engender a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes familiar patterns. One of the implications of the intuitive style of executive management is that " thinking" is inseparable from acting. Since managers often "know" what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is inextricably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert. Given the great uncertainty of many of the management issues that they face, senior managers often instigate a course of action simply to learn more about an issue. They then use the results of the action to develop a more complete understanding of the issue. One implication of thinking/ acting cycles is that action is often part of defining the problem, not just of implementing the solution.
