In science the meaning of the word “explain” suffers with civilization’s every step in search of reality. Science cannot really explain electricity magnetism, and gravitation; their effects can be measured and predicted （预测）, but of their nature no more is known to the modern scientist than to Thales who first speculated on the electrification of amber(琥珀). Most present physicists reject the notion that man can ever discover what these mysterious forces “really” are. Electricity, Bertrand Russell says, “is not a thing, it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances 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. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, so one can deduce that objects fall to the ground because that’s where they belong, and smoke goes up because that’s where it belongs. The goal of Aristotelian science was to explain why thins happen. Modern science was born when Galileo began trying to explain how things happen and thus originated (使成起源 )the method of controlled experiment which now forms the basis of scientific investigation.
