"Great Development of Science and Technology" Science, Culture and Social Life in the 20th Century PPT Courseware 2

Problem Leadership (The Third Scientific and Technological Revolution)

1. What are the new technological inventions in the third technological revolution?

2. What are the characteristics and impacts of the third technological revolution?

3. What impact will the third technological revolution have?

4. Review the past and learn the new

How many technological revolutions has human history experienced?

A list summarizing the similarities and differences between the three technological revolutions

electronic calculator

A. The first tube computer

B. The first transistor computer in 1956

C. The first integrated circuit computer in 1964

D. The first PC

Talk about it

Can you tell the development direction of electronic computers after entering the fourth generation based on the prompts in the picture?

The calculation speed is fast, with a calculation speed of more than 100 million times per second.

Significance: The emergence of electronic computers is a milestone in the liberation of human intelligence

Internet Age

Since the 1990s, computers have entered the network age.

The communication network connects the computing center and computers distributed in various places to form a computer network, which expands the application scope of computers.

Utilization of Atomic Energy

At the end of 1942, the United States built the world's first atomic reactor

Impact: Humanity has since entered the atomic energy age.

Three atomic bombs were made in 1945 and used in World War II, dropped on Hiroshima and Nagasaki in Japan.

The Soviet Union also developed the atomic bomb in 1949

In 1954, the Soviet Union built its first nuclear power plant, which was the beginning of mankind's peaceful use of atomic energy.

Characteristics of the Third Scientific and Technological Revolution

Material 1: The steam engine took 84 years from invention to application, the electric motor took 65 years, and the radio took 35 years. Most of the technologies in the third technological revolution took less than 10 years, such as the utilization of atomic energy in 6 years and the electronic computer in 5 years. , 4 years for transistors, and only 1 year for lasers.

The transformation of science and technology into productivity is accelerating;

Material 2: For example, bioengineering technology can be applied to medicine, and electronic computers can be used in industry and agriculture, scientific research, education, national defense construction, etc.

The various fields of science and technology interpenetrate each other;

Material 3: The scale and speed of the development of "technology-intensive" enterprises greatly exceeds that of "labour-intensive" enterprises. At the beginning of the 20th century, the proportion of science and technology in the gross national product was 5%-10%. In the 1970s, increased to 60% and reached 80% in the 1980s

Technology has become the most active factor in productivity and promotes economic growth

The impact of the third scientific and technological revolution

Material 1: The development of modern science and technology has also changed the internal structure of productivity, from labor-intensive and resource-intensive to knowledge-intensive and technology-intensive; from high-material and high-energy-consuming to material-saving and energy-saving; from primary technology-based Transform into high-tech. Transform from physical labor to mental labor. Ushering in the era of knowledge economy!

Promote the unprecedented development of social productivity.

Material 2: High and new technologies have become the commanding heights that drive a country’s economic development. Countries around the world are competing fiercely in the high-tech field. In addition to Europe's "Eureka" plan, there are also the United States' "Star Wars" plan, the "Information Superhighway" plan, Japan's "Technology Nation" strategy and China's " "863 Plan" and so on, the world economic structure is moving towards multi-polarization.

Cause changes in the world economic structure and international economic pattern.

Promote the multi-polarization of the world economic structure.

Technology is a double-edged sword:

positive influence:

(1) Promote productivity and economic development,

(2) Improve our lives; enrich people’s material and cultural life, improve people’s quality of life; change people’s lifestyles and ways of thinking;

(3) Improve people’s work efficiency;

(4) It facilitates people’s travel and strengthens connections between people.

negative impacts:

(1) War issues: aircraft, airships, tanks, poison gas bombs, long-range artillery, etc. in World War I; atomic bombs in World War II

(2) Environmental issues: large amounts of domestic garbage, waste gas, space waste, nuclear waste, etc.

(3) High-tech crimes: Internet “hackers”, methamphetamine, etc.

(4) Other problems: teenagers are addicted to online games, etc.

Practice questions for high school entrance examination

Which of the following combinations of achievements and impacts of the three scientific and technological revolutions is completely correct ( )

A. Watt’s improved steam engine—the development of large factories

B. The "Voyager" test run was successful - water transportation developed rapidly

C. The invention of the electric motor - the car became a popular means of transportation

D. Bioengineering-promoted the invention of electronic computers

Read the pictures and answer the following questions based on the knowledge you have learned:

(1) Figure 1 is the most representative achievement of which technological revolution? What trends does Figure 2 reflect in today’s world economic development?

(2) What are the trends in the development of today’s world political landscape?

(3) What impact does the technological revolution represented in Figure 1 have on the two trends of today’s world economy and politics?

(1) The third scientific and technological revolution (1 point) (Economic) Globalization (1 point)

(2) (Political landscape) Multipolarity (1 point)

(3) The scientific and technological revolution has accelerated the process of economic globalization; (1 point)

Science and technology promote economic development, promote the process of economic globalization, and thereby promote a multi-polar world structure. (1 point)
