3_1.1_pop4,James Clerk Maxwell(1831 1879)Scottish physicist,B R _ 3_1.1_Script1,He was a Scottish physicist.His most revolutionary achievement was his demonstration that light is an electromagnetic wave,and he originated the concept of electromagnetic radiation.He established the nature of Saturns rings,did important work on color perception,and produced the kinetic(动力的)theory of gases.He was an English mathematician and scientist who invented differential calculus(微分学)and formulated the theory of universal gravitation,a theory about the nature of light,and three laws of motion.His treatise on gravitation was supposedly inspired by the sight of a falling apple.,A.B.,B R _ 3_1.1_Script2,He was a German-born American theoretical physicist whose special and general theories of relativity revolutionized modern thought on the nature of space and time and formed a theoretical base for the exploitation of atomic energy.He won a 1921 Nobel Prize for his explanation of the photoelectric(光电的)effect.He was a German physicist whose work on the second law of thermodynamics(热力学)and blackbody radiation led him to formulate the revolutionary quantum(量子)theory of radiation.He

to think that to make it move,but the fact that the needle of the compass behaved in such a fixed way made him realize that,light,space and time,_,one thing has to touch another,_,something deeply hidden had to lie behind things,_.,B R _ 3_2_2.1,2.Isaac Newton,Watch a video clip about Isaac Newton and tell whether the following statements are true or false.,1)According to Newton,the force that made the apple fall from the tree was different from the force that kept the moon and planets in their orbits.,2)Moon is being pulled by the earths gravity and is actually falling around the planet.,B R _3_2_2.2,F,They are the same force,the force of gravity.,(),T,(),4)The strength of the gravity is determined by the volume of the object,the greater the volume,the stronger the gravity.,3)Gravity

distance from each other.,(),B R _3_3.1,The Great Plague of London,Listen to a passage about The Great Plague of London and answer the following questions.,1.When was the plague particularly violent?,It was particularly violent during the hot months of August and September of 1665.,2.How was the plague carried?,The plague was carried by fleas that lived on black rats.,B R _3_3.2,3.Which parts of the city were most severely affected by the plague?,The citys outskirts and areas where the poor were densely crowded were most severely affected.,4.Why did the plague decline?,The plagues decline was attributed to various causes,including the Great Fire of London.,The Great Plague of London(1664 1666)was an outbreak of bubonic(鼠疫)plague that struck London and was particularly violent during the hot months of August and September of 1665.In one week,7,165 people died of the plague.The total number of deaths was about 70,000 of a total population estimated at 460,000.The disease was carried by fleas that lived on black rats.It was generally incurable,and its effects were terrible fever and chills,swelling of the lymph glands,eventual madness and death.Most of the devastation was in the citys outskirts,in areas where the poor were densely crowded.Those who could,including most doctors,lawyers,B R _3_3.3,B R _3_3.4,lawyers and merchants,fled the city.All trade with London and other plague towns was stopped,but from 1667 only sporadic cases appeared until 1679.The plagues decline was attributed to various causes,including the Great Fire of London.,B R _3_4.1,Silicon Valley,Listen to an introduction about Silicon Valley and tell whether the following statements are true or false.,Silicon Valley is the northern part of the San Francisco Bay Area in Northern

high-tech hub.,T,(),2.The term“silicon valley”refers to the most advanced companies in the field of information technology.,F,The term has three layers of meanings:1)silicon chip innovators and manufacturers in the area;2)high-tech business in the area;3)the whole high-tech sector.,(),B R _3_4.3,Silicon Valley is the southern part of the San Francisco Bay Area in Northern California,United States.The term originally referred to the regions large number of silicon chip innovators and manufacturers,but eventually came to refer to all the high-tech businesses in the area;it is now generally used as a metonym for the high-tech sector.Despite the development of other high-tech economic centers throughout the United States,Silicon Valley continues to be the leading high-tech hub because of its large number of cutting-edge entrepreneurs,engineers and venture capitalists.,B R _ 4.1_San Francisco Bay Area,B R _ 4.1_Northern California,B R _ 4.1_silicon chip,B R _ 4_1,Lead-in Discussion,Walter Isaacson,who authored the book Einstein:His Life and Universe,is talking about his impression of Einstein in a radio program.Listen and answer the following questions in small groups.,1.Does Isaacson think Einstein was the most knowledgeable and intelligent person among the physicists of his time?,No,but he thinks Einstein was the most imaginative and creative one.,B R _ 4_2,2.According to Isaacson,what do the people in his country need today?,Today the country needs a sense of imagination,a sense of creativity in the fields of science,world affairs and anything else.,3.What does Isaacson mean when he says that“Einstein was no Einstein when he was a kid”?,He means that Einstein was slow in learning how to talk when he was a child and was rebellious.,B R _ 4_3,4.How did Einstein benefit from his slow verbal learning ability?,He learned to think in pictures and visualize things instead of thinking in words,which contributes to his creativity.,5.What role do you think intelligence,knowledge and creativity play respectively in Einsteins way to success?Discuss with your classmates and explain your answer to them.,G R _ main,Part Division of the Text,Further Understanding,G R _ Further Understanding_ main,For Part 1 Discussion,For Part 2 True or False,For Part 3 Table Completion,Further Understanding,For Part 4 Questions and Answers,G R _ Part Division of the Text 1,Part Division of the Text,Parts,Para(s),Main Ideas,1,13,2,412,A young husband and father,Albert Einstein had to work hard to support his family.,Einstein made astonishing achievements in physics and thus revolutionized the field.,G R _ Part Division of the Text 2,Parts,Para(s),Main Ideas,3,1321,Einsteins discoveries were attributable to his imagination,questioning,disregard for authority,powers of concentration,and interest in science.,4,2223,Einstein was not a space alien.,G R _ 2_1,Discussion,In this part,Einstein was portrayed as a young working father who strived to shoulder the job and family responsibilities and strike a balance between the two.Discuss with your partner and list the possible reasons why the author portrayed Einstein this way.,On the one hand,the author aroused readers interest and curiosity about Einstein by presenting an image different from the stereotyped one of a bushy-haired superthinker;on the other hand,the author intentionally used this image as an echo to the title,indicating that Einstein was not a space alien.,2.In his theory of quantum mechanics,Einstein proposed that space and time were threads in a common fabric.,G R _2_2.1,True or False,F,In his theory of special relativity,Einstein proposed that space and time were threads in a common fabric.,(),1.Einsteins job as a professor of physics enabled him to publish five important papers in 1905.,F,Four years before Einstein got a job as a professor of physics,he published five important papers in 1905.,(),4.According to Peter Galison,if Einstein hadnt been born,his 1905 papers would eventually have been written in some form by others.,3.Einstein came from the same place where Newton grew up.,G R _2_2.2,T,(),F,Einstein and Newton came from different places but both of them enjoyed high reputation in the world.,(),G R _ 2_3.1,Table Completion,Factors contributing to Einsteins achievements,Supporting facts,disregard for authority,1.Einstein proposed that light was made of particles,disagreeing with James Clerk Maxwell,an Authority Figure of his time.2.Einstein wasnt beholden to a thesis advisor or any other authority figure after he received his Ph.D.in 1905.,G R _ 2_3.2,Factors contributing to Einsteins achievements,Supporting facts,ability to question,Einstein was constantly doubting and questioning in the school,enraging his 7th grade teacher.,belief in intuition and inspiration,Einsteins failure to understand lights duality didnt slow him down,instead,he adopted the intuitive leap as a basic tool.,G R _ 2_3.2,Factors contributing to Einsteins achievements,Supporting facts,interest in science,Science was dinner-table conversation in the Einsteins household.,powers of concentration,Einstein would engross himself in a problem in spite of the background noise at parties.,G R _ 2_4,Questions and Answers,1.What did Einstein struggle to do later in life?Did he succeed in his effort?,He struggled to produce a unified field theory,combining gravity with other forces of nature,but he failed.,2.Why did Dr.Thomas Harvey remove Einsteins brain without permission in 1955?,Because he would like to see whether Einsteins brain was different from that of others.,D R _ Text 1,WAS EINSTEIN A SPACE ALIEN?,Tony Phillips,Albert Einstein was exhausted.For the third night in a row,his baby son Hans,crying,kept the household awake until dawn.When Albert finally dozed off it was time to get up and go to work.He couldnt skip a day.He needed the job to support his young family.,D R _ Text 2,Walking briskly to the Patent Office,where he was a“Technical Expert,Third Class,”Albert worried about his mother.She was getting older and frail,and she didnt approve of his marriage to Mileva.Relations were strained.Albert glanced at a passing shop window.His hair was a mess;he had forgotten to comb it again.,Work.Family.Making ends meet.Albert felt all the pressure and responsibility of any young husband and father.,D R _ Text 3,To relax,he revolutionized physics.In 1905,at the age of 26 and four years before he was able to get a job as a professor of physics,Einstein published five of the most important papers in the history of science all written in his“spare time.”He proved that atoms and molecules existed.Before 1905,scientists werent sure about that.He argued that light came in little bits(later called“photons”)and thus laid the foundation for quantum mechanics.He described his theory of special relativity:space and time were threads in a common fabric,he proposed,which could be bent,stretched and twisted.,D R _ Text 4,Oh,and by the way,E=mc.Before Einstein,the last scientist who had such a creative outburst was Sir Isaac Newton.It happened in 1666 when Newton,secluded himself at his mothers farm to avoid an outbreak of plague at Cambridge.With nothing better to do,he developed his Theory of Universal Gravitation.,D R _ Text 5,For centuries historians called 1666 Newtons“miracle year.”Now those words have a different meaning:Einstein and 1905.The United Nations has declared 2005“The World Year of Physics”to celebrate the 100th anniversary of Einsteins“miracle year.”Modern pop culture paints Einstein as a bushy-haired superthinker.His ideas,were told,were improbably far ahead of other scientists.He must have come from some other planet maybe the same one Newton grew up on.,D R _ Text 6,“Einstein was no space alien,”laughs Harvard University physicist and science historian Peter Galison.“He was a man of his time.”All of his 1905 papers unraveled problems being worked on,with mixed
