Stephen Hawking is one of the most famous scientists in the world. He was born in 1942. He's a famous scientist and expert on space and time. Stephen is trying to find the answers to some very big questions, such as: how did the universe begin? How will it end? These questions are very hard for us to understand. But they are very important and can tell us many things about the universe.

Stephen studied Maths and science when he was a student at university. Then, at the age of twenty-one, he became sick. He was so young, but the doctors said to his family, “He has only two more years to live.” As a matter of fact, the doctors were wrong — he didn't die. He can't walk now but he uses a wheelchair. He can't feed himself and get in or out of bed himself. But he refuses to give in. He talks with the help of a computer. After Oxford, Stephen went to Cambridge University. Three years later, in 1965, he became a Doctor of Philosophy.

Because of his serious health problem, it was difficult for him to draw diagrams (图表) or write. So he started to think in pictures. With this new way of thinking, he became one of the most famous scientists in the world. In 1981, he met the Pope (教皇) in Rome. They talked about his ideas. Then in 1988, he wrote his first important book, A Brief History of Time. It was sold more than 5.5 million copies in 33 different languages. He was once invited to China. He impressed us with his self-confidence and humorous conversation.
