Part One: The Rise of the Third Technological Revolution

1. Start time: 1940s and 1950s.

2. Core: The invention and widespread application of electronic computers.

In 1946, the world's first electronic computer was born in the United States. Since then, it has rapidly expanded to developed countries such as Western Europe and Japan, and gradually extended to developing countries, eventually forming a worldwide technological revolution.

3. condition:

(1) The great achievements of the scientific revolution in the 19th century provided the theoretical foundation for the third scientific and technological revolution.

(2) The two world wars, the Cold War, and fierce international competition under peaceful conditions have become powerful stimuli and huge levers for the third wave of scientific and technological development.

(3) The socialization of science and technology, organized large-scale investment and planned development by governments of various countries, have created conditions for the accelerated development of science and technology.

4． Development areas:

Electronic computers, space science and technology, biotechnology.

Contemporary scientific and technological revolution and social life PPT, part 2: main achievements of the third scientific and technological revolution

1. The arrival of the information age

(1) Development of electronic computers:

After the birth of electronic computers, countries have continued to develop more powerful and efficient computers. Computers are becoming increasingly lighter in size, storage capacity continues to expand, and running speeds are greatly improved.

(2) Development of information technology

① Information technology with computer networks as its core is developing rapidly.

②After the 1990s, with the development of the international Internet and digital communications, the radius of human communication has expanded infinitely through the information highway.

③Today, information highways spread all over the world, and human society has entered the information age.

The Internet is an information transmission network composed of computers and computer networks connected to each other. It is a brand-new communication medium. In the 1990s, British scientist Berners-Lee invented the World Wide Web (abbreviated as "www") and resolutely refused to apply for a patent, making "surfing the Internet" no longer a "privilege" for professionals. As a result, the Internet has become rapidly popularized, and hundreds of millions of ordinary people can easily use network resources.

(3) The impact of information technology development:

The development of information technology has given rise to the emerging information industry, making it the main growth point of economic growth. Take Silicon Valley in the United States as an example. It has gradually developed due to the rapid development of computer technology and has now become synonymous with high-tech industries. Under this influence, more and more countries regard the development of information technology as an important goal to enhance international scientific and technological competitiveness.

2. Development of space technology

(1)Performance:

Since the 1950s, the development of space technology has enabled mankind to realize the dream of flying into space. Artificial earth satellites, manned spacecraft, and space shuttles have all greatly promoted human exploration of space.

(2) Impact:

These explorations not only develop space science and technology, but also drive the development of related science and technology.

3. Biotechnology

It emerged in the 1970s and has become one of the high technologies in the world today. The birth of Dolly the cloned sheep in 1996 marked the advent of a new era of biotechnology.

What makes Dolly unique is that it was not born through sexual reproduction, but the product of cloning technology, and all of its genetic characteristics come from almost the same sheep. The birth of Dolly means that humans can use a tissue cell of an animal to mass-produce identical life forms.

Contemporary scientific and technological revolution and social life PPT, the third part: the impact of the third scientific and technological revolution

1. Overview:

Every major breakthrough in the development of science and technology will lead to social progress. Contemporary social life has seen many new changes and presented new characteristics.

2. Performance:

(1) More and more women are beginning to step out of the family and into society, gaining equal political, economic and other rights with men.

(2) Under the slogan "knowledge is power", people pay more attention to learning, and a learning society is taking shape in which everything must be learned, learning can be done everywhere, and learning can be done at all times.

(3) The improvement of social productivity, the richness of consumer products and the diversity of consumption methods have changed people's consumption concepts and contributed to the formation of a consumer society.

(4) People not only pay more attention to improving the quality of material life, but also pay more and more attention to enriching their spiritual life. Expenditures on non-material consumption such as learning, traveling, and sports are on the rise.

Contemporary scientific and technological revolution and social life PPT, part 4: similarities and differences in the impact of the three scientific and technological revolutions

difference:

①The first industrial revolution: led to the emergence of two directly opposing classes, the bourgeoisie and the proletariat.

②The first industrial revolution: Promoted the transition of capitalism from the free competition stage to the monopoly stage.

③The third technological revolution: Promote the development of state monopoly capitalism (the combination of monopoly and state power).

Same point:

① All have created huge social productivity and promoted rapid economic development.

② They have greatly changed people’s lifestyles.

③All have contributed to changes in the world structure.

Contemporary scientific and technological revolution and social life PPT, part six: extracurricular development

With the development of science and technology, it is no longer a fantasy for chickens to "give birth" to ducks. The team of scientists who developed the world's first cloned sheep, Dolly, announced a new breakthrough: using genetic modification technology, they made a chicken lay duck eggs and successfully hatched them. Scientists plan to use this technology to create chickens that can produce reproductive cells from different birds. This approach has the potential to save endangered birds and even bring back extinct birds.

How to create different kinds of "offspring"?

Scientists need to extract the cells that make sperm and eggs from bird embryos, and then implant them into the reproductive organs of chicken embryos. When the genetically modified chickens grow up, they begin to produce sperm from that species of bird, giving birth to "alien" offspring. The research team hopes to use this method to make chickens give birth to different species of birds.
