Knowledge Q&A

1. What is the core of the third technological revolution?

widespread use of electronic computers

2. The time when the third scientific and technological revolution emerged: the 1940s and 1950s

3. In which fields has the third scientific and technological revolution achieved major breakthroughs?

Atomic energy, computers, aerospace technology, bioengineering, etc.

Characteristics of the third technological revolution:

Fast speed - the speed at which technology is converted into productivity has been greatly accelerated, shortening the process of turning knowledge into material wealth.

Wide scope - various fields of science and technology penetrate each other, and the development of one technology causes revolutions in several technologies.

Big impact - new technologies have become the most active factor in social productivity. Among the various factors that promote economic growth, the proportion of scientific and technological progress continues to rise.

For example, what negative effects will the rapid development of technology bring?

1. Vehicle exhaust emissions cause air pollution

2. The use of pesticides causes harm to the human body

3. Long-term use of mobile phones will cause slight microwave radiation to the human brain, and the working frequency of mobile phones is similar to the navigation radar of the aircraft. Passengers using mobile phones during the takeoff and landing of the aircraft may cause interference and cause the aircraft to deviate from the course or even crash.

4. Due to the continuous leakage of the refrigerant Freon in refrigerators and air conditioners, the ozone layer in the atmosphere has been seriously damaged, resulting in an increase in the intensity of ultraviolet radiation on the ground, and an increase in the number of people suffering from skin diseases.

In the face of the positive and negative effects of the third technological revolution, what concepts should we have?

In the development of science and technology, we must pay special attention to the improvement of the quality of the living environment, focus on sustainable development, and avoid advantages and disadvantages.
