Science is a branch of knowledge system that reflects the objective laws of nature, society and thinking. Science refers to the application of universal truths or theorems that have been discovered, accumulated and recognized, as well as systematic and formulaic knowledge.

There are many different interpretations of the definition of science:

Cihai (1999 edition): "Science: a knowledge system that uses categories, theorems, laws and other thinking forms to reflect the essential laws of various phenomena in the real world.

French Encyclopedia: "Science is different from common sense at first, and science seeks order in things through classification. In addition, science tries to explain things by revealing the laws that govern things. "

Encyclopedia of the former Soviet Union: "Science is the category of human activities, and its function is to summarize and systematize the knowledge about the objective world. The concept of' science' itself includes not only the activities of acquiring new knowledge, but also the results of such activities. "

Introduction to modern science and technology: "It can be simply said that science is systematic knowledge that truthfully reflects the internal laws of objective things."

Classification of science: according to different research objects, it can be divided into natural science, social science and thinking science, as well as philosophy and mathematics that generalize and run through the three fields; According to the different connection with practice, it can be divided into theoretical science, technical science and applied science. According to the direct degree of human utilization of natural laws, science can be divided into natural science and experimental science; According to whether it is suitable for human goals, science can be divided into broad science and narrow science. Each classification can be divided into many branches. For example, the branches of natural science include space science, earth science, environmental science, life science, life science and physics. The branches of social science are anthropology, economics, psychology and geography.

I often read the magazine "We Love Science", which not only makes me understand a lot of scientific knowledge, but also enriches my life and makes me happier. I summed up the characteristics of this magazine: "the most unexpected", "the most adventurous", "the most intelligent" and "the most interesting". I especially like it.

We love science because of its great function. Science and technology are the primary productive forces. Science can promote the development of social productive forces. The transformation of science into social productive forces requires certain conditions, that is, making full use of science to serve social practice. To fully apply science, we need to know science, deeply understand science and constantly improve the level of science and technology.

We love science because it is so profound and mysterious. Such as: exploring the mysteries of nature; Explore the mysteries of the biological world; Explore the mysteries of space, and so on.

We love science because it can change and improve our work, production and life.

We love science, because science education can revitalize the country and the nation.
