1、 what if we lived without scien _? great changes have taken pla _ in the world with the help of scien _. in the past, life was nasty, brutish and short. it is hard to i _gine how our forefathers could do without so _ny convenien _s that modern scien _ brings about. back then, only a s _ll group of p
2、eople enjoyed the very few forts. but the _jority of people didnt even have sufficient food, let along their privilege to be educated. anyway, it is scien _ that changes the world and _kes peoples life better and better, although it also leads to some bad aspects at the same time. from the discovery
3、 of the gravity to the first step on the moon, we hu _n beings have experien _d a long pro _ss of developing scien _. and now, this pro _ss is still continuing much faster. new organi _s are already being engineered, and new geically modified crops promise benefits from higher yields and less use of
4、 harmful chemicals and so on. a lot of examples are showing this point. in the future, changes are likely to be even much greater as scien _ reaches out to shape life itself. _ybe one day, the possibility that life existed on _rs billions of years ago will be potentially one of the greatest discover
5、ies of our time. it is the for _ of the petition, we hu _n beings inquiring mind and initiative that bring about the non-stopped development of scien _. therefore, it is difficult and impossible to prevent scien _ from changing the world and our life as well. at present, we are in two minds about sc
6、ien _. on the one hand, we are enjoying the sweet life as a result of the evelopment of scien _, and expect it to continue. and we are showing our interests into some scientific expeditions, such as the astronomy, the alien civilization, etc. on the other hand, we are distrustful of it, due to the l
7、ack of understanding of scien _. some people thus far are still very superstitious, and they would even believe in superstitions rather than believe in scien _. stephen hawking, one of the most re _rkable scientists in the world, on _ said, “in a democratic society, the public needs to have a basic
8、understanding of the scien _, so that it can _ke informed decisions and not leave them in the hands of experts.” this has reminded me of professor alan g. _cdiarmid from america, the person who got the nobel prize for chemistry in the year of xx. in his lecture at peking university this year, he put
9、 forward that scien _ is people. he also expounded the importan _ of the basic scien _ for the public. evidently, every one of us does need scien _, or we cant live without it. now that everyone needs scien _, why not take advantage of some means to give the public the right basic scientific knowled
10、ge? so when they fa _ the problems such as acid rain, the greenhouse effect, nuclear weapons, enviro _ent destruction and some other problems, they can also _ke informed decisions on these subjects, just as what hawking said. one aspect relies on what is taught in schools. but scien _ is often taugh
11、t in an uninteresting way and most students just learn it by rote to pass examinations. however, the final goal of learning scien _ is not to pass examinations or to get a higher score; instead, we should try to _ke full use of it to change our world and life. while learning, we should try to ask mo
12、re questions and we should have the courage of suspecting the knowledge in the books, as some of the scientific conclusions are likely to be corrected in the future. who knows. so not only must we change our attitude towards scien _, but also the way of teaching and learning scien _. in addition, sc
13、ien _ is always changing at a fast rate, and who we learn at school isnt that sufficient to last a lifetime. so the _ss media including tv, radio, newspaper, _gazine and publishing pany will play an important role in reporting the latest scien _ in time. moreover, the _ss media can also popularize b
14、asic scien _ to the public, because only in this way will more people realize what on earth scien _ is. “scientists and engineers tend to express their ideas in the form of equations because they need to know the precise values of quantities. but for the rest of us, a qualitative grasp of scientific
15、 con _pts is sufficient, and this can be conveyed by words and diagrams, without the use of equations”, said stephen hawking. i agree with him very much, and, im fond of the wonderful words above, from stephen hawking. for the development of scien _, are you ready? float , is my favorite book.like t
