A. In the past two days, the greatest achievement was that the method was also a tool and an invisible tool! To understand why a method is a tool and what has in common with tangible tools, such as hammers, you must first understand what tools are and how they are used. Tools are used to achieve a certain goal. Whether or not the tools are good or bad directly affects the completion of the trust service. Some tasks cannot be completed without tools. The quality of the tools is reflected in the efficiency and quality of the tasks.

B. I was wondering, what are the direct benefits of system theory for developing drivers? Generally, what are the benefits of system theory to design? Think about it. If design and work are more of a dynamic process concept, the system and design are not in the same dimension, that is, they are complementary. System Theory helps to understand the world, and design theory helps to transform the world. Understanding the world is a prerequisite for transforming the world.

B. Another question: How does system theory help people understand the world? In what ways does design theory help people transform the world? This reminds me of the tool theory methodology! That is, the system theory is partial mechanization of the process of understanding the world, and the design theory is partial mechanization of the process of transforming the world.

A. descartes believes: "methods, I mean indeed and simple rules. If someone follows them accurately, he will never regard false things as true, he will never spend his mental efforts unpurposefully, but will gradually increase his knowledge, in this way, we can get a real understanding of all things that do not exceed his abilities. The definition of Cartesian "method" is a narrow definition, because the method has a special purpose-to increase knowledge! Therefore, this is a definition of "cognitive methods". Therefore, according to the definition of this "special tool", we can generalize from "cognitive methods" to "methods" to "Tools.

We know that we must use a hammer when installing a nail on the wall, and we have no Essentials or impractical hands. Then, we can imagine that the features of a hammer as a tool are: first, it has a handle that applies to people holding it; second, it has a hammer iron that replaces a hammer hitting a nail. That is to say, there are two ends of the hammer, and each end has different rules and features. Descartes said, "methods, I mean indeed and simply rules. If someone exactly follows them," The structure of the tool is obtained: the tool must have at least two ends, each end has different rules, and the rules at one end must be applicable to people. The rules at the other end are different for specific jobs. Again, "If someone follows them accurately, he will never regard false things as true", that is, the use of tools is reliable, di said, "He will never make his mental efforts to spend without destination", which means that using tools saves some things and costs, such as strength, time and space, compared with not using them; "and will always gradually increase his knowledge" means that the design of the tool stems from a specific purpose, such as obtaining a certain benefit and value.

 

View the "two ends" rule from the process of using the tool

From the tangible tool first, hand a hand to hammer a nail, hand a hammer to wave this action can be done, this is the tool availability first, the hammer to hit a nail this action is linked to the previous action, moreover, nails must be placed on the wall after several such actions, which is the purpose of the tool design and the usefulness of the tool.

What are the situations at both ends of intangible tools, such as methods? What can people do at one end? What about the other end? What is the link between the two ends?

Language is a tool, mathematics is a language, and model is also a language. The production of natural language facilitates people's life and production, and is a daily tool. Mathematics is a refined language, this makes it easy for people to study the number of things and the form of space. mathematical models are special parts of mathematical language. Different mathematical models are created for different problems to facilitate the study of this special problem. Natural language, mathematics, and mathematical models are both intangible tools-Methods of thinking, and they have hierarchies. Language is not completely invisible yet. It uses words as a carrier and strengthens the mechanization of language tools.

A. the two ends of the tool can be listed in the program subroutine. In principle, a subroutine provides a convenient interface to the caller. Isn't this convenient interface a tool?

A. The tools used to produce entity tools are entities. The tools used to produce thinking tools are abstractions, and subprograms are abstractions.
