Scientific definition
Science is an orderly knowledge system based on test -available interpretations and predicting the form of objective things and organizations. It is a systematic and formulating knowledge.The object is objective phenomenon, the content is formal scientific theory, and the form is language, including natural language and mathematical language.
Scientific classification
Modern science is usually divided into three main branches, natural sciences (such as: biology, chemistry and physics, etc.), studying the social sciences of individuals and society (such as economics, psychology, and sociology), as well as the form of studying abstract conceptsScience (such as logic, mathematics, computer science).But whether formal science really constitutes a science is different because they do not rely on empirical evidence.In addition, disciplines that use existing scientific knowledge in actual purposes such as engineering and medicine are called applied science.
Scientific scope
In ancient and modern Chinese and foreign, all scientific success is scope. That is to say, the verification of a scientific research result is based on certain conditions. When conditions change, the scientific conclusion will change with it.In the eighteenth century, the scientific community proposed the law of conservation of quality, that is, in any material system (isolated system) isolated from the surrounding, no matter what changes or processes occurred, the total quality remains unchanged.For example, after the water is frozen, it becomes ice, which is a physical change. In the end, the quality of water and ice is the same. The iron is iron into iron water, and the quality will not change.Chemical changes in hydrogen and oxygen will become water. The quality of hydrogen and oxygen is the same as the quality of water.However, at the beginning of the 20th century, scientists found that the quality of high -speed sports objects changed with its movement speed, and found that the physical and field could be transformed into each other. Therefore, the quality of the field should be considered according to the quality of quality.The development of quality concept has made the principle of conservation of quality also develop new. The laws of quality conservation and energy conservation are merged into a conservation law through quality energy relationships, that is, the law of conservation of quality energy.
Scientific thinking and scientific achievements
Science is a form, a way of thinking, a process from observation, inference, assumptions, to verification, and to repeatedly verify the process.Many people equate science and scientific achievements. In fact, the two are different concepts.Scientific thinking is rigorous, objective, and rational, and the scientific results are conditional. It is verified based on the conditional condition of the existing cognition. It is limited and gradually improves as the cognitive improvement.
