[单项选择]In science the meaning of the word "explain" suffers with civilization’s every step in search of reality. Science can not really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modem scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul’s Cathedral; it is a way in which things behave."
When we have told how things behave when they are electrified, we have told all there is to tell. Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of ’reality by reasoning from self-evident principles.

Science and Scientist

The word science is heard so often in modern times that almost everybody has some notion of its meaning. On the other hand, its definition is difficult for many people. The meaning of the term is confusing, but everyone should understand its meaning and objectives. Just to make the explanation as simple as possible, suppose science is defined as classified knowledge (facts).
Even in the true sciences distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses (假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited (使不相信). The exact status of any explanation should be clearly labeled to avoid confus
A. the study of unrelated subjects
B. an attempt to explain natural phenomena
C. the study of unrelated fields
D. classified knowledge
