The tape recorder is one of the most welcome and popular electronic devices ever invented. It is not only esteemed by teachers, research workers,Air Shox NZ Men Shoes ID:61671
administrators but also by many students. They like their recorders as much as or more than their TV sets and radios and some regard them as good companions. This device is useful in many ways. It can be used in learning,teaching, sporting, and entertaining. For example, it is an essential instrument for students to learn foreign languages, for English teachers to make their classes lively and interesting and for people to enjoy their music. Besides, it can also be used in mass media. With it, Air Shox NZ Men Shoes ID:61669
journalists can record what government officials,spokesmen or interviewees say. However,it can also become a nuisance if we use it improperly. Too loud music played by the recorder causes noise pollution, thus affecting other people's rest and too loud music from walkman damages people's hearing. Air Shox NZ Men Shoes ID:61677
So we must make good use of the tape recorder. Even the most complicated computer man has yet built can't compare in intricacy with the brain. Computer switches and comportents number in the thousands rather than in the billions.What's more, the computer switch is just an on-off device,whereas the brain cell is itself possessed of a tremendously complex inner structure.
Can a computer think?Air Shox NZ Men Shoes ID:61672
That depends on what you mean by"think". If solving a mathematical problem is"thinking',then a computer can"think'and do so much faster than a man. Of course, most mathematical problems can be solved quite mechanically by repeating certain straightforward processes over and over again. Even the simple computers of today can be geared for that. Surely, though, if a computer can be made complex enough,Air Shox NZ Men Shoes ID:61668
it can be as creative as we are. If it could be made as complex as a human brain, it could be the equivalent of a human brain and do whatever a human brain can do. But how long will it take to build a computer complex enough to duplicate the human brain? Perhaps not as long as some think. Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself. Air Shox NZ Men Shoes ID:61670
This more complex computer could design one still more complex and so on and so on and so on. In other words, once we pass a certain critical point, the computers take over and there is a"complexity explosion". In a very short time thereafter, computers may exist that not only duplicate the human brain--but far surpass it. Leaders don ' t force other people to go along with them. They bring them along. Leaders get commitment from others by giving it themselves, Air Shox NZ Men Shoes ID:61673
by building an environment that encourages creativity, and by operating with honesty and fairness.
