Using language, one, read the texts and decide if the statements are true or false. The father of china's arrow space, perhaps no other scientists, has had a greater impact on china's airspace science. Then tin n, described by the authors of the story of chin sue son as a man with great scientific thought and scientific spirit, who was patriotic and served his homework with effort, achievement and devotion, was an extremely well respected man. Born in shanghai in nineteen eleven, chen attended schools in beijing and then entered shanghai jiang university to study railway mechanical engineering. However, after the song who battle broke out in nineteen thirty two, chen made the decision to switch his major to aviation because he realized that needed its own powerful air force to protect and defend the country. Chen went to the united states in one hundred and thirty five to pursue his graduate studies. Over the course of the nineteen thirties and nineteen forties, chen became a pioneer in american jet and rocket technology as a graduate assistant at the california institute of technology. During the nineteen thirties, chen helped conduct important research into rocket propulsion, and in the sixties, he, in several other people, founded the jet proportion laboratory, now one of nurses leading space exploration centers. After overcoming some difficulties during his final few years in the U. S, kenn returned to china. In one nine hundred fifty five. He received a hero's welcome from his homeland and and was put in charge of not only developing china's rocket science, but also its space in mission program. At that time, china was poor and its rocket science was undeveloped. No institute or university in china offered rocket science as a major, and there were no talents or experts in this field in china. Nevertheless, chen did not let that discourage him from taking on the chAllenge. When he was asked, can we chinese possibly make missile? His reply was a determined, why not we chinese are able to make the same things that other people make. Under chins leadership, china developed the dong fung missiles es, followed by the first generation of long march rockets. In nineteen seventy, china successfully launched its first man made satellite, dong fang hong one from a long march rocket, because much of the technology behind the sandro spacecraft can also be traced back to chen's research, chen earned the name of the father of china's era space chian read a lot and was extremely knowledgeable, especially in the area of frontier science research. However, what might have made him such an outstanding and creative scientist was probably his strong interest in other things, such as music and drawing. His deep appreciation for art often gave him inspiration in his scientific research. On october thirty first two thousand nine, the whole country was saddened by chen's death, and people honored and remembered him in different ways. A world of pure thought, Stephen hawking was one of the most famous and gifted scientists in physics. Most people are familiar with images of him in his wheelchair, unable to move on using a computer to talk, since he came down with a disease which caused him to lose the use of most of his muscles, his world became one of abstract thought. Hawking first achieved fame when he was still healthy enough to walk as a graduate student in physics at cambridge, a university in one hundred and sixty four. In general, there were two main theories on the origin of the universe. The first was the steady state theory, which holds that the universe has no beginning or end. The other was the big bang theory, which holds that the universe began at a single point in time and space. The biggest champion of the steady state concept was fred hole, a professor at cambridge. During the question and answer period after one of hal's lectures, hawking stood up and pointed out that hole had made a mistake in his maths. Once the maths was corrected, IT showed that the big bang theory, and not the steady state theory, was true. Hooking zone work on the big bang theory was soon proven by astronomers with telescopes. A star was born. So what made Stephen hawking a genius? Besides, it's being brilliant. He was brave, though sometimes careless, in what he said, or did. He was willing to say what others were afraid to say and to dream of what others were afraid to dream about. Furthermore, he was quite determined this had helped him as a scientist and had helped him even more in his fight against his disease. Above all, hawking was willing to admit his fault. This thought combination of characteristics had made him one of the greatest thinkers of the twenty eighth and twenty first centuries.
