Human mind or machine, which is smarter? That is a question has been discussed for many years. Basically, I believe that human intelligence is prior for it is human that designs machines to help solve problems. However, no one can deny that machines are more useful under some scientific circumstances.   Human minds are superior than machines for humans know how to use these tools. People have the desire to free themselves from heavy work and to do their work more efficient so that they intend to use machines to replace them to do some simple and repeated work. When scientists do research, they know how to use some kinds of machines to reduce their workload. Geologists use computer to analyze the massive data they collect from rock samples to picture the climate fluctuation in the past million years. Archaeologists, instead of looking through all the ancient documents, use carbon dating to determine the actual age of a ancient site. It is obvious that without using these tools, people may slow down their pace of knowing the past or cannot achieve success in scientific fields.   Also, human minds are smarter because they can do analysis that the machines cannot complete. In fact, machines can be seen as a simple-mind worker: it can do something by following instructions but it cannot find out what to do except the requirments. When it comes to the study of literature, machines seems to be less able to help solve problems. Study of literature mainly relies on human minds because it is not about a specific formula or a general principle. It needs reconstruction of the work's background .It needs analysis about other works in that period. It needs to link the work to the writer’s life. All of these, however, are beyond a machine's ability.   However, exceptions do exist. For one thing, we rely on calculators to help us solve basic mathematic problems. Sometimes we have no confidence about our ability of calculating. For another, it seems that we cannot master the machines designed by ourselves, like the out-of –control nuclear plants. But there is one thing to remember: we invent the calculating machine, and behind the screen showing the results is our intelligence. We can avoid the threats of nuclear power by improving the design of the reaction.   In conclusion, I agree that our human minds are intelligent than the machines we make, although machines are more useful in some aspects than our minds. After all, machines embodies only part of our intelligence.
