关于科学家的英语作文


Here is a difference between science and technology.Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools,techniques, and procedures for implementing the findings of science.
Another distinction between science and technology has to do with the progress in each. Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth with the highest degree of accuracy and certainty, cannot pay heed to their own or other peoples likes or dislikes, or to popular ideas about the fitness of things. What scientists discover may shock or anger people--as did Darwins theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we h**e the option of refusing to believe it! But hardly so with technology;we do not h**e the option of refusing to hear the sonic boom produced by a supersonic aircraft-flying overhead; we do not h**e the option of refusing to breathe polluted air. Unlike science, progress in technology must be our sl**e and not the reverse. The legitimate purpose of technology is to serve peopie--people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves.
We are all familiar with the abuses of technology. Many people blame technology itself for widespread pollution, resource depletion and even social decay in general--so much so that the promise of technology is obscured. That promise is a cleaner and healthier world. If wise applications of science and technology do not lead to a better world, what else will?
