单选题It has always been difficult for the philosopher or scientist to fit time into his view of the universe. Prior to Einsteinian physics, there was no truly adequate formulation of the relationship of time to the other forces in the universe, even though some empirical equations included time quantities. However, even the Einsteinian formulation is not perhaps totally adequate to the job of fitting time into the proper relationship with the other dimensions, as they are called, of space. The primary problem arises in relation to things which might be going faster than the speed of light, or have other strange properties. Examination of the Lorentz-Fitzgerald formulas yields the interesting speculation that if something did actually exceed the speed of light it would have its mass expressed as an imaginary number and would seem to be going backwards in time. The barrier to exceeding the speed of light is the apparent need to have an infinite quantity of mass moved at exactly the speed of light. If this situation could be leaped over in a large quantum jump—which seems highly unlikely for masses that are large in normal circumstances—then the other side may be achievable. The idea of going backwards in time is derived from the existence of a time vector that is negative , although just what this might mean to our senses in the unlikely circumstance of our experiencing this state cannot be conjectured. There have been, in fact, some observations of particle chambers which have led some scientists to speculate that a particle called the tachyon may exist with the trans-light properties we have just discussed. The difficulties of imagining and coping with these potential implications of our mathematical models points out the importance of studying alternative methods of notation for advanced physics. Professor Zuckerkandl, in his book Sound and Symbol, hypothesizes that it might be better to express the relationships found in quantum mechanics through the use of a notation derived from musical notations. To oversimplify greatly, he argues that music has always given time a special relationship to other factors or parameters or dimensions. Therefore, it might be a more useful language in which to express the relationships in physics where time again has a special role to play, and cannot be treated as just another dimension. The point of this, or any other alternative to the current methods of describing basic physical processes, is that time does not appear—either by common experience or sophisticated scientific understanding—to be the same sort of dimension or parameter as physical dimensions, and is deserving of completely special treatment, in a system of notation designed to accomplish that goal. One approach would be to consider time to be a field effect governed by the application of energy to mass—that is to say, by the interaction of different forms of energy, if you wish to keep in mind the equivalence of mass and energy. The movement of any normal sort of mass is bound to produce a field effect that we call positive time. An imaginary mass would produce a negative time field effect. This is not at variance with Einstein"s theories, since the "faster" a given mass moves the more energy was applied to it and the greater would be the field effect. The time effects predicted by Einstein and confirmed by experience are, it seems, consonant with this concept.

单选题Few of us take the pains to study our cherished convictions; indeed, we almost have a natural ______ doing so.

单选题In the early 1950's, historians who studied preindustrial Europe (which we may define here as Europe in the period from roughly 1300 to 1800) began, for the first time in large numbers, to investigate more of the preindustrial European population than the 2 or 3 percent who comprised the political and social elite: the kings, generals, judges, nobles, bishops, and local magnates who had hitherto usually filled history books. One difficulty, however, was that few of the remaining 97 percent recorded their thoughts or had them chronicled by contemporaries. Faced with this situation, many historians based their investigations on the only records that seemed to exist: birth, marriage, and death records. As a result, much of the early work on the nonelite was aridly statistical in nature; reducing the vast majority of the population to a set of numbers was hardly more enlightening than ignoring them altogether. Historians still did not know what these people thought or felt. One way out of this dilemma was to turn to the records of legal courts, for here the voices of the nonelite can most often be heard, as witnesses, plaintiffs, and defendants. These documents have acted as "a point of entry into the mental world of the poor." Historians such as Le Roy Ladurie have used the documents to extract case histories, which have illuminated the attitudes of different social groups (these attitudes include, but are not confined to, attitudes toward crime and the law) and have revealed how the authorities administered justice. It has been societies that have had a developed police system and practiced Roman law, with its written depositions, whose court records have yielded the most data to historians. In Anglo-Saxon countries hardly any of these benefits obtain, but it has still been possible to glean information from the study of legal documents. The extraction of case histories is not, however, the only use to which court records may be put. Historians who study preindustrial Europe have used the records to establish a series of categories of crime and to quantify indictments that were issued over a given number of years. This use of the records does yield some information about the nonelite, but this information gives us little insight into the mental lives of the nonelite. We also know that the number of indictments in preindustrial Europe bears little relation to the number of actual criminal acts, and we strongly suspect that the relationship has varied widely over time. In addition, aggregate population estimates are very shaky, which makes it difficult for historians to compare rates of crime per thousand in one decade of the preindustrial period with rates in another decade. Given these inadequacies, it is clear why the case history use of court records is to be preferred.
