1, the meaning of science Science: the use of categories, theorems, laws and other forms of thinking to reflect the nature of the real world of various phenomena of the rule of knowledge system. Families,Science refers to the knowledge that has been systematized and formulated by the discovery, accumulation and acceptance of universal truths or the application of universal theorems. The definition of science: "Science is to sort out facts, to find laws from them, and to draw conclusions." The connotation of science is facts and laws.
2. "Science" cannot be defined precisely in short words. Generally speaking, science covers three meanings: observation: the effort to reveal the truth about nature, and the action of nature by adequate observation or study (including thought experiments), usually that which can be carried out by necessary means or by the scientific method, a set of procedures for evaluating empirical knowledgeYes. Assumption: The systematicness of organizational system knowledge is assumed through such a process.
3, science, refers to the division and learning, and then refers to the various knowledge through detailed classification (such as mathematics, physics, chemistry, etc.) research, the formation of a gradually complete knowledge system. It is a knowledge about discovery, invention and creation practice, and a general term for the knowledge system of human exploration, research and perception of the changing laws of everything in the universe. Science is a system of ordered knowledge based on testable explanations and predictions about the form, organization, etc., of objective things.
4, science is the method of testing by practice and infinite access to truth. implyIt refers to the study of various knowledge through detailed classification (such as mathematics, physics, chemistry, etc.) to form a gradually complete knowledge system. It is a knowledge about discovery, invention and creation practice, and a general term for the knowledge system of human exploration, research and perception of the changing laws of everything in the universe.
5, the meaning of science Science is a systematic method of knowledge and research, aimed at exploring the objective laws of nature, society, the universe and other phenomena, and through practice to verify and continuously improve these understandings. Science is not only the accumulation of knowledge, but also a way of thinking about exploring and solving problems. Here's a breakdown of what the science meansThe accumulation and inheritance of knowledge.
Question 1: What does the word science mean? The word science refers to the discovery, accumulation, and acceptance of the application of universal truths or universal theorems, this knowledge has been systematized and formulated. Science is the process of summarizing, concluding and verifying the known world by means of data calculation, text interpretation, language explanation and image display. Although science is one of the broad ways to understand the world, it is fair.
