1. According to the different research objects, it can be divided into natural science, social science and thinking science, as well as philosophy and mathematics that summarize and run through the three fields.
2. According to the different connections with practice, it can be divided into theoretical science, technical science, applied science, etc.
3. According to the direct degree of human use of natural laws, science can be divided into two categories: natural science and experimental science.
4. According to whether it is suitable for human goals, science can be divided into two categories: broad science and narrow science.
5. Science that has matured and is recognized by society is called"Explicit science"Science that is not yet mature and is still in the budding stage can be called"Latent science"。
Science refers to the study of different disciplines, and then 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 general term for the knowledge system of human exploration, research and understanding of the laws of change in the universe.
Science is a system based on testable explanations and orderly knowledge of the forms, organizations, etc., of objective things. In an old, closely related sense, "science" also refers to the subject of reasonably explainable and reliably applied knowledge itself. Professional practitioners of science are customarily referred to as scientists.
Since classical times, science as a form of knowledge has been closely linked. The scientific method lays the foundation, emphasizing the reproducibility of experimental data and their results.
In the Western world, the words "science" and "natural philosophy" are sometimes used interchangeably. In the Western world until the 17th century, natural philosophy (later becoming the natural sciences) was considered an independent branch of science of philosophy, cognate with materialism.
In modern usage, "science" often refers to the pursuit of knowledge, not only as a way of knowledge itself, but also as a way of studying the phenomena of these branches that seek to explain the material world.
In the 17th and 18th centuries, scientists increasingly sought to develop knowledge of the laws of nature, such as Newton's laws of motion. And over the course of the 19th century, the term "science" became more and more associated with the scientific method itself.
Disciplined methods for the study of the natural world, including physics, chemistry, geology, and biology. It was in the 19th century that the term scientist was also created by naturalists to distinguish between natural knowledge and knowledge.

In 480 BC, the Persian Emperor Xerxes I personally led an army of 100,000 to attack Greece. At this time, Greece was still a city-state (i.e., a city as a kingdom, each with its own king's alliance), and due to lack of preparation, the alliance was loose, and almost most of the Greek city-states surrendered, leaving only the most powerful Athens and Sparta. The Persian envoys came to Sparta to tell the king Leonidas that they only needed "water" and "earth" (meaning to make them surrender), but the messengers were pushed down the abyss, so Xerxes was angry and prepared to personally attack Athens and Sparta. >>>More
1. Moderate price. Always the focus of attention in procurement activities. One of the most concerned about the procurement of enterprise managers is how much procurement money the purchasing department can save, so the purchasing manager should put a lot of time and energy on the "bargaining" with the best businessmen. >>>More
According to the lean dictionary "Lean Lexicon" compiled by the Lean Research Institute of the United States, which is presided over by the lean master Womach, the definition of a single piece flow or continuous flow is: "one (or a small, fixed batch) workpiece is produced and moved at a time, so that the workpiece passes through a series of processing steps as continuously as possible, and each step is just completed when the next step is needed." Continuous flow can be achieved in a variety of ways, from mobile assembly lines to manually transferred production cells. >>>More
