The benefits brought to us by the development of science and technology

The benefits brought by scientific and technological development include:

1. Economic development: China's labor productivity is only one fortieth of that of developed countries. Once science and technology are transformed into productive forces, it will greatly improve production efficiency, thus promoting rapid economic development, and its role greatly exceeds the transformation of the economy by capital and labor.

2. Military combat effectiveness: In today's world, peace and development are the themes of the times. However, the "cold war" mentality still exists, and hegemonism and power politics are still the main sources that threaten world peace and stability. It is the same choice for a powerful country in science and technology to become a modern country.

3. Political influence: The level of modern science and technology has become a bargaining chip in the international political struggle and a symbol of great power status. Deng Xiaoping once pointed out: "If China had no atomic bombs, hydrogen bombs and satellites since the 1960s, China would not have become a big country with more important influence, nor would it have such an international status."

4. Social progress: The productivity of scientific and technological development has created a highly developed material civilization, but the improper use of science and technology has caused extremely serious environmental problems worldwide.

Extended data?

The development of science and technology not only facilitates life, but also harms people's health. The latest article published by MSN Life Network in the United States shows that the development of science and technology, especially the popularization of electronic products, mainly leads to the following diseases:

1, phone separation anxiety. An experiment conducted by psychologists at the University of Essex in the United Kingdom confirmed that the anxiety of mobile phone separation affects more and more young people. Once the mobile phone is not around, they immediately show symptoms of anxiety and distraction, which is very similar to gambling addiction.

2. Computer vision syndrome. Staring at the computer screen for a long time can easily lead to computer vision syndrome. The main symptoms include: eye fatigue, blurred vision and headache. To alleviate this kind of problem, it is best to reduce the time of watching the screen, blink frequently and do eye exercises to give your eyes a full rest.

3, halo screen disease. The phenomenon of dizziness and nausea caused by facing the screen of digital products for a long time is called "screen disease" Some people get dizzy when they browse quickly on their mobile phones. The reason is that the moving content on the screen will make users feel dizzy, sick and headache, just like a bumpy boat on the sea.

4, bulimia. There are more and more mouth-watering food pictures or videos on mobile phones and computers. Studies have found that they can stimulate people's appetite. Many people are not really hungry, but eat a lot of foods they shouldn't eat, consume too many calories, and even overeat, which increases the risk of obesity and related diseases.

5, insomnia. Many studies have found that the blue light generated by mobile phones, computers and other screens will affect sleep time and sleep quality. A study on 20 16 found that the incidence of insomnia was as high as 42% among participants who used mobile phones for a long time; 35% of the participants who used mobile phones for relatively little time also had sleep problems. People who use mobile phones before going to bed have worse sleep quality.
