10、was an eminent scientist,inventor,engineer and innovator who is credited with inventing the first practical telephone.(right:Bell at the opening of the long-distance line from New York to Chicago in 1892.)Thomas Alva Edison(1847 1931)Edison was a famous inventor.His workshops located in Menlo Park(r

11、ight),NJ,brought forth the system of motion picture,the phonograph and a long-lasting,practical electric light bulb.He developed many devices that greatly influenced life around the world.He was one of the first inventors to apply the principles of mass production and large-scale teamwork to the pro

12、cess of invention,and he credited with the creation of the first industrial research laboratory.II.The Early and Mid-Twentieth Century Frederick Winslow Taylor:developing the science of management based on his time-motion studies;Henry Ford:an American industrialist,and sponsor of the development of

13、 the assembly line technique of mass production The growth of the broadcast radio business in America;The developing household technologies:the refrigerator,home oil furnaces,washing machines,vacuum cleaners,electric dishwashers,etc.Frederick Winslow Taylor(1856 1915)Frederick Winslow Taylor was a m

14、echanical engineer who sought to improve industrial efficiency.He is regarded as the father of scientific management and one of the intellectual leaders of the Efficiency Movement.His theory known as Taylorism was highly influential in the Progressive Era.Henry Ford(1863-1947)Henry Ford was the foun

15、der of the Ford Motor Company and sponsor of the development of the assembly line technique of mass production.He developed and manufactured the first automobile that many middle class Americans could afford.His Model T automobile (right)revolutionized transportation and American industry.The Growth

16、 of the Broadcast Radio BusinessAt first,radio was used only for the transmission of messages from one point to another.Only amateurs experimented with the system of broadcasting widely to many potential listeners.David Sarnoff,an employee of Marconis company,had plans for profitable radio broadcast

17、ing in 1916.So,in 1920 the first commercial broadcasting station,KDKA,began broadcasting from Pittsburgh,PA to a small group of listeners.After World War I,the growing broadcast radio business served many functions.It provided entertainment,news,information,and advertisements to feed a growing consu

18、merism in America.The Growth of the Broadcast Radio Business During the economic depression of the 1930s,President Franklin D.Roosevelt held Fireside Chats in an effort to restore confidence in the economy and in the government.The Developing Household Technologies Household technologies include inv

19、entions such as the refrigerator,home oil furnaces instead of coal burning ones,automatic laundry machines,vacuum cleaners,electric dishwashers.These inventions as well as the newer ones such as the microwave oven,the electric blender,the food processor,and so on,should have freed housewives from te

20、dious work and made much more time available to them.Careful study shows however that women today spend more time on household chores than in the past.III.The Late Twentieth Century and Today Television and the Age of Visual Information;Militarily useful inventions;US Space Race with the U.S.S.R;Nuc

21、lear development;Computers;The Internet;Renewable energy technologiesTelevision and the Age of Visual InformationTelevision developed fast After WWII.The pioneers of television believed that the primary use of this new device would be educational.But experience showed that sports activities,quiz sho

22、ws,and theatrical shows were more popular.At the end of the century,it was apparent that American schoolchildren were spending less time studying,and less time playing sports,and more time sitting passively in front of a TV set.Adults too were addicted to TV.With the wide spread of TV,the Age of Vis

23、ual Information had arrived.Militarily Useful Inventions As World War II approached,the U.S.military began to sponsor research into militarily useful inventions leading to significant technical developments useful for military purposes.Yet in peacetime many of these military developments found a use

24、 in the wider society:radar for traffic control,microwave cooking(using the radar microwave generator for heating),nuclear energy,peaceful uses of computers.US Space Race with the U.S.S.R On 4 October 1957,the Soviet Union successfully launched Sputnik 1 into space,the first artificial satellite to

25、orbit the Earth,making the USSR the first space power.Four months after the launch of Sputnik 1,the United States successfully launched its first satellite,Explorer 1,becoming the second space power and entering the Space Race with the USSR.The Space Race became an important part of the cultural,tec

26、hnological,and ideological rivalry between the United States and the Soviet Union during the Cold War.US Space Race with the U.S.S.R In 1961,the then President John F.Kennedy announced that America would land a man on the moon by the end of the decade.His goal was fulfilled by the Apollo 11 mission

27、when the mission commander Neil Armstrong became the first human to set foot on the lunar surface on 20 July 1969.Nuclear DevelopmentBy August 1945,the Allied Manhattan Project had successfully detonated an atomic device and subsequently produced atomic weapons based on two alternate designs.In Augu

28、st 1945,during the final stage of the Second World War,the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki.Nuclear Development After WWII,nuclear reactors were developed to generate electricity.Nuclear developments in the USA suffered a major setback after the 197

29、9 Three Mile Island accident.Nevertheless,by 1990 over 100 commercial power reactors had been commissioned.Now there are more than 110 nuclear power reactors in 31 states,generating almost 20%of total electricity produced in this country in 2008.The USA is the worlds largest producer of nuclear powe

30、r,accounting for more than 30%of worldwide nuclear generation of electricity.Computer ScienceElectronic computers originally were developed to assist artillery to predict the path of fired shells,and also to break enemy cryptographic messages.These machines were enormous in size,using miles of wires

31、 and thousands of vacuum tubes.They consumed great quantities of electricity.Peacetime applications seemed limited.(right:early computers)Computer Science It was up to two young visionary tinkerers,in the American tradition of amateur inventors,to devise a smaller,personal computer(PC).Young Steve J

32、obs,working in his garage with his friend Steve Wozniak,was finally able to package a small desktop computer that could process symbols.Another young man,Bill Gates devised a set of instructions,a Disc Operating System,or DOS.Computer ScienceSteve Jobs(1955-2011)was an American entrepreneur,marketer

33、,and inventor who was the co-founder,chairman,and CEO of Apple Inc.Through Apple,he is widely recognized as a charismatic and design-driven pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields,transforming“one industry after anoth

34、er,from computers and smart phones to music and movies.”Jobs oversaw the development of the iMac,iTunes,iPod,iPhone,and iPad.The success of these products propelled Apple to become the worlds most valuable publicly traded company in 2011.Computer ScienceBill Gates (1955-)is an American business magn

35、ate,philanthropist,inventor,computer programmer,and inventor.Gates is the former chief executive and chairman of Microsoft,the worlds largest personal-computer software company,which he co-founded with Paul Allen.He is consistently ranked in the Forbes list of the worlds wealthiest people and was th

36、e wealthiest overall from 1995 to 2009excluding 2008,According to the Bloomberg Billionaires List,Gates became the worlds richest person again in May 2013.In the later stages of his career,Gates has pursued a number of philanthropic endeavors,donating large amounts of money to various charitable org

37、anizations and scientific research programs through the Bill&Melinda Gates Foundation,established in 2000.Bill GatesThe InternetThe potentials of computerized technologies can never be exaggerated.Perhaps the most powerful one is the Internet.It emerged in the Unites States in 1968 during the period

38、 of the Cold War,the original idea being to connect computers housed at military strategic locations throughout the US for the purpose of saving the information in the event of a nuclear attack.Later four universities in the American West were connected to the system.Over the years after 1969 more a

39、nd more computers were joined to the system and increasing information was added to its database.Many educational,private and commercial networks joined in.Useful tools were invented such as the e-mail and www(the World Wide Web).Renewable Energy TechnologiesToday,climate change concerns,coupled wit

40、h high oil prices,are propelling the fast growth of renewable energy technologies.Renewable energy is generated from natural resources such as sunlight,wind,rain,tides,and geothermal heat.It has low or zero carbon emissions.America is engaged in developing such green energy technologies.Clean renewa

41、ble energy technologies have an increasingly large market and a bright future.Questions for DiscussionA.What role does technology play in our lives?Does it only provide new conveniences or does it sometimes change our life style?Give examples from the text to illustrate your ideas.B.Who are some of the greatest inventors in the US?C.What do you think is the greatest invention so far?WhyD.What do you know about Bill Gates and Steve Jobs?E.Discuss what role the Internet plays in your life.
