Relevant scientific and technological knowledge

Society is used to linking science and technology together, collectively referred to as "science and technology". In fact, there are both close ties and important differences between them. Science solves theoretical problems and technology solves practical problems.

The problem to be solved by science is to discover the relationship between facts and phenomena in nature and establish a theory linking facts and phenomena; The task of technology is to apply scientific achievements to practical problems.

Science mainly deals with unknown fields, and its progress, especially major breakthroughs, is unpredictable; Technology works in a relatively mature field and can make more accurate planning.

The essence of science and technology:

Discover or invent the connection between things, through which various substances form a specific system to achieve specific functions.

1. Traditionally, science is a system of knowledge about nature, society and thinking accumulated by human beings.

2. What we call "science" refers to the natural science that studies natural phenomena and their laws; Technology generally refers to various tools, equipment, technologies and process systems combined for a practical purpose according to the production practice experience of natural science principles, but does not include the technical content corresponding to social science.

3. Science and technology are dialectical unity. Technology puts forward the topic and completes it scientifically. Science is the discovery of technology and theoretical guidance. Technology is an invention and a practical application of science.

The significance of science:

Science and technology are the primary productive forces.

Throughout the ages, every progress of human society is accompanied by the progress of science and technology. In particular, the rapid development of modern science and technology has opened up a broader space for the development of social productive forces and human politeness, which has effectively promoted economic and social development.

The rapid growth of high-tech enterprises such as computer, communication, biomedicine and new materials in China has greatly improved the industrial technology level of China, promoted the labor productivity of industry and agriculture, and effectively promoted the development of the whole national economy. Practice has proved that high-tech and its industries have become the leading industries in contemporary economic development.

Technology is a sign of human politeness. The progress and popularization of science and technology provide mankind with new means to spread ideas and culture, such as radio, television, movies, videos and the Internet, which provides a new carrier for the construction of spiritual politeness. At the same time, it is of great significance to enrich people's spiritual life, update people's ideas and get rid of superstitions.

Small knowledge of science and technology

1. Why do the stars twinkle?

We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere. The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency will change according to its density. So when we look at the stars through it on the ground, we will see what the stars seem to be flashing.

2. Why can snakes walk without feet?

Snakes have many scales, which are the outermost armor on their bodies. Scales are used not only to protect the body, but also to protect the feet. When a snake crawls forward, its body will be S-shaped. Every scale outside the S-shape will tilt upward to help the snake catch the uneven road when it moves forward. These scales cooperate with the snake's muscles and can push the body forward, so the snake can walk without feet!

3. Why do sunflowers always bloom towards the sun?

Sunflower discs contain a substance called auxin in the lower part of the head and stem. This substance has the function of accelerating replication, but it is anti-optical, and it will run to the backlight side whenever it encounters light. So when the sun rises, the stem of the sunflower immediately hides to the side of the backlight, as if the whole plant is bent in the direction of the sun.
