Science and Technology
There is a difference between science and technology. (46)__________ Science has to dowith discovering the facts and relationships between observable phenomena in nature and withestablishing theories that serve to organize these facts and relationships; technology has to dowith tools, techniques, and procedures for applying the findings of science. (47)__________
Progress in science excludes the human factor. Scientists, who seek to understand the universe and know the truth within the highest degree of accuracy and certainty, cannot payattention to their own or other people's likes or dislikes or to popular ideas about the fitness of things. (48)__________. But even an unpleasant truth is more than likely to be useful; besides wehave the choice of refusing to believe it ! But hardly so with technology; we do not have thechoice of refusing to hear the sound produced by a supersonic (超音速的) aircraft flyingoverhead ; we cannot refuse to breathe polluted air. (49)__________The purpose of technology is toserve people -- people in general, not merely some people; and future generations, not merelythose who presently wish to gain advantage for themselves.
(50) __________Many people blame technology itself for widespread pollution, resourcedepletion (枯竭) and even social decay in general -- so much so that the promise oftechnology is " obscured ". That promise is a cleaner and healthier world. If wise applicationsof science and technology do not lead to a better world, what else will?
