In the book, Hawking explains both what it means to be a scientist and how science works. He tells readers how discoveries are made and how they change the world . Science, according to Hawking, is often misundertood: people often think that science is about "ture " facts that never change. Scientists, on the hand , Hawking writes, know that their job is never finished and that even the best thory can out to bewrong.
Ascientific theory is the result of the scientific method. scientists look at the world and try to describe and explain what they see . First, they carefully observe what they are interested in. To explain what they have seen , they build a theoty about the way in which things happen and the causes and effects. Finally, the scientists test the theory to see if it matches what they have seen and if it can predict future events. If what they are observing can be tested in a practical way , scientists will use experiments. But if , like Hawking , they are studying something that is too large or too difficult to observe directly , they will use a model to test the theory.
People who listen to Hawkong's lectures sometimes find it diffcult to understand him , because his thoughts and ideas often seem as large as the universe he is trying to describe . The speech computer is not the problem . In fact , people who hear it often say it sounds just like a human voice . Hawking is happy with it ,too . " The only trouble , " says Hawking , who is British , "is that it gives me an American accent ."
