4 Background Information Stephen William HawkingStephen William Hawking was born on 8 January1942 (300 years after the death of Galileo) in Oxford,England. At eleven Stephen went to St Albans School,and then on to University College, Oxford, his father'sold college. Because mathematics was not availablethere, he had to do Physics instead.4
5 After three years and not very much work he was awarded a first class honors degree in Natural Science.Stephen then went on to Cambridge to do research inCosmology, there being no-one working in that areain Oxford at the time. After gaining his Ph.D. he becamefirst a Research Fellow, and later on a ProfessorialFellow at Gonville and Caius College.After leaving the Institute of Astronomyin 1973 Stephen came to the Departmentof Applied Mathematics and TheoreticalPhysics, and since5
6 ＋－× ÷？ ！1979 has held the post of Lucasian Professor of Mathematics. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for Cambridge. It was first held by Isaac Barrow, and then in 1669 by Isaac Newton.For much of his academic life, Hawking has been among a group of theoretical physicists searching for a "theory of everything" – one unified scientific theory that explains the big cosmological questions like How did the universe begin? Why is the universe the way it is and How will it end?6
7 In the late 1960s, Hawking proved that if general relativity is true and the universe is expanding, a singularity must have occurred at the birth of the universe. In 1974 he first recognized truly remarkable property of black holes, objects from which everything even light was not supposed to be able to escape.Hawking is one of the world's leading theoretical physicists. Many consider him to be the most brilliant since Einstein. He's even had a TV cameo role in Star Trek in which he plays poker with scientific iconsThe background picture: It is a picture of a galaxy in Harbor Astronomical Telescope’s maiden constellation called NGC4261. It displays that dust and air is spinning into a large mass of black hole.7
8 Sir Isaac Newton and Albert Einstein. Yet when asked about comparisons between himself and the two scientists,he calls it all "media hype." Onceasked how he felt about being labeled the world's smartest person, he responded: "It is very embarrassing. It is rubbish, just media hype. They just want a hero, and I fill the role model of a disabled genius. At least I am disabled, but I am no genius.” Hawking has ALS (amyotrophic lateral sclerosis), a disease that progressively weakens muscle control.8
9 As a 21-year-old graduate student in cosmology at Cambridge, doctors predictedan early death for him.Today, he's 62 and married with threechildren. He gets around in a wheelchair,and after completely losing the use of hisvocal chords in an operation to assist his breathing in 1985, he communicates through a computer. A speech synthesizer "speaks" for him after he punches in what he wants to say, selecting words in the computer softwareby pressing a switch with his hand. Unfortunately, it9
10 makes him sound like he has an American accent, he says. He has written the internationalbestseller A Brief History of Time.The book 10spent morethan fouryears on the LondonSunday Times bestsellerlist --the longest run forany book in history andhas been translated into40 languages10
11 and has sold ten million copies and has sold ten million copies. His other famous books include Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell.(The Chinese Version)11
12 Warming-up Activities Form groups to figure out some of the scientific and technological discoveries that have changed the way people live.Some group leaders read out to the whole class their discussion results.Determine in what ways these discoveries change our lives for the better and in what ways for the worse.12
13 We can’t deny the fact that plastics, dynamite, batteries,cars, fridges, TV, cell phones,computers and many other scientific and technological inventions have greatly contributed to the improvement of our society and our living standards. However, we at the same time have to admit that they have also done us damagein one way or another.Take plastics as anexample. It is a goodsubstitute forUpper left: products made of plasticsLower right: white pollution
14 wood and even iron andsteel in industry, and plastic bags make our life more convenient. However, rivers, lakes and banks full of plastic rubbish are never unusual.Take another example. Cars have greatly enhanced the efficiency of man’s work and life, but they are also the first killer of human lives. It seem that the same scientific andtechnological discoverycan bring us good thingsand bad things. It is neithergood or bad in itself, but liesin how we use it.Airplanes, air crashes; delicate cars and car accidents
