Nine sentences for engineers

Nine sentences for engineers 1. What is engineering?

Engineering is the concrete practical activity that people use scientific theories and technical means to transform the objective world, and the actual results achieved.

Engineering is not a purely theoretical work. When carrying out practical activities, engineering needs to use scientific theories and technical means.

Scientific theory includes both natural science and social science.

Engineering is a comprehensive work in the whole science and technology engineering system. The comprehensive use of natural science, social science and technical means is the basis for the project itself to be carried out.

2. What is the relationship between science, technology and engineering?

Science, technology and engineering are three different things and three different categories.

Science is the result of people's exploration of nature, human society and all. Exploring nature is natural science, exploring society is social science, exploring process is scientific activity, and exploring result is theoretical system. Science basically belongs to the category of understanding the world, including the natural world and human society.

Technology is the means used by human beings in the process of transforming the world.

There is a close relationship between science and technology. It can be said that science cannot move without technical means.

The specific practical activity that people use scientific theories and technical means to transform the objective world is engineering. Therefore, the relationship between engineering and science and technology is also very close. There are two words for engineering, one is scientific engineering and the other is engineering science.

Scientific engineering itself is an engineering, but it serves science. For example, nuclear physics research requires an accelerator, which is a huge scientific project.

Engineering science is the scientific basis needed by the project itself. Science includes both pure science and applied science. Engineering science is a part of applied science.

3. What is the role of the project?

The role of the project is mainly reflected in the following aspects:

First, the project can promote economic growth.

Economic growth is nothing more than two ways, one is extension, the other is connotation. The extension is to carry out new projects, and the connotation is to transform old enterprises. Even in the tertiary industry, there are also a large number of engineering technology applications, such as bank payment.

Second, the project can promote social progress.

Engineering can promote social progress, such as the popularization of computer technology.

Third, engineering is the concrete embodiment of the first productivity.

The theoretical basis of engineering as the embodiment of the first productive force is that science itself can only be a theory. To have practical effects, it must be realized through engineering.

Finally, engineering is a very important way to cultivate talents.

The student trained by the school is not a mature engineer. He (she) can only be trained through engineering practice.

4. What are the main characteristics of the project

First, it is scientific. Contemporary engineering must be based on science. Without science, engineering cannot be carried out;

Second, the project has a great social nature. Modern projects need to be carried out by a group, not by one or two people. Engineering is different from pure science. Pure science can be carried out independently by one or two scientists;

Third, the practicality of the project. Engineering itself is a practical activity, so it is not an imagination, which is very different from science.

Science advocates whimsical thinking. You can think whatever you want and let your mind fly freely. Those who engage in science will not achieve anything if they can't put their thoughts aside.

However, the project is not allowed to daydream, and those who engage in the project cannot say that it cannot be achieved;

Fourth, the innovation of the project. Innovation is not the same thing as invention. An invention can be patented, but whether it has been put into practice is not the key. Technological innovation or economic innovation is more economic than pure technological concept;

Fifth, the project is very complex. First, there are many uncertain factors in the project; Secondly, many problems of the project are restricted by objective conditions; Third, many projects are not a single solution. They have various solutions.

5. What is the definition of engineer?

An engineer is a professional person who can master the engineering technology within a certain range and lead relevant personnel to engage in specific practical activities to achieve results.

6. What qualities should a qualified engineer have?

A qualified engineer should have the following qualities:

1) Analytical ability

Engineers should have the ability to analyze the structure, process, function, material and other aspects of their work (including design, production, service, etc.);

2) Practical ability

Due to the complexity of technology, many problems have not been formed in theory or have no ready-made theory to guide them. Engineers can only judge by experience and are good at summarizing the regularity of things from practice;

3) Observation ability

Engineers should have keen observation, that is, the ability to find problems. Engineers should be good at finding defects, deficiencies and irrationality in things that people are accustomed to, so as to improve them;

4) Creativity

Engineers should have discovery, invention and creation in practice, and be able to solve engineering problems that have not been solved by predecessors through comprehensive analysis with interdisciplinary knowledge and theories mastered;

5) Learning ability

Engineers should have a good grasp of the basic knowledge required for their work. Be good at learning from practice, books and absorbing new knowledge.

An excellent engineer is also a person who loves science. Both the common sense and the spirit of science will permeate his life.

There are high requirements for engineers' physics and mathematics foundation. The physics and mathematics mentioned here refer to the most basic knowledge rather than the superficial words and formulas.

6) Communication ability

Engineers should have good communication skills. Must be good at communicating with relevant personnel in writing or orally;

7) Management ability

Engineers shall scientifically manage the documents, data and information formed by their technical and development work;

8) Rigorous style

Engineers must work in accordance with standards, be meticulous, rigorous, conscientious and responsible, meticulous and keep improving;

9) Excellent character

Engineers should be good at working with others, especially those with different opinions and personalities;

10) Professionalism

Engineers should love the work they are engaged in, be loyal to their duties and fulfill their duties. Take pride in work and take pleasure in work.

7. What are the requirements for the education of engineers?

Because engineering is a specific practical activity for people to comprehensively use scientific theories and technical means to transform the objective world, engineering education should be undertaken by engineering colleges, that is, engineers must have the background of studying in engineering colleges.

What people are trained in engineering colleges? Some people say it is to train engineers, and others say it is to train engineers. I agree with the latter. Rough parts may become finished products or waste products. Therefore, students who graduate from the college cannot become engineers directly. Even good students can become qualified engineers after a period of training.

8. What is the relationship between engineering and engineers?

The relationship between engineering and engineers is very close.

It has been defined earlier that engineering is the specific practical activity and the actual results that people use scientific theories and technical means to transform the objective world. There is no doubt that people here refer to engineers.

9. How to understand the knowledge structure that engineers should have?

In order to better understand the knowledge structure that excellent engineers should have, I propose a knowledge structure axis that engineers should have (Figure 1).

We can regard the knowledge structure that engineers should have as a three-axis space. There is a three axis, the horizontal axis, which deals with the material field; The longitudinal axis is about the work of human beings; The space axis is about the natural field.

1) Logistics axis

The logistics axis is the first resource. There are three major resources in resources, one is material, one is energy or energy, and one is information.

Materials are the material basis of our society. In the history of mankind, the ages are divided to a large extent on the basis of materials, including the Stone Age (including the Paleolithic Age and the Neolithic Age), the Bronze Age and the Iron Age. The second classification of materials is divided into structural materials and functional materials in terms of function, and the third classification is divided into metallic materials and non-metallic materials.

The issue of energy is very important. Lenin once said that communism is the Soviet plus electrification. Energy is a carrier of energy generation. There are five main forms of energy carriers: coal, oil, natural gas, water and nuclear power.

Information. Information system has a problem of information itself, information media and carrier. Information media is the form of information. Information carrier is the physical body on which information exists.

Information is different from material and energy. Material is consumed when it is consumed, and energy change is nothing more than this energy changing into another energy, but this energy is still consumed. The biggest feature of information is that it can be copied indefinitely.

2) Working axis

The work axis includes research, development, design, manufacturing, operation, etc.

Research. The research we are talking about here, where there is an intersection between engineering and science, is more applied research.

development. Development and research are different. The research is to see whether the principle is feasible or not. The development is to make a thing based on this principle and make the principle concrete.

Design. It can be said that design is the weakest link in our country. At present, there is no product design institute in China. There is a certain intersection between design and development. Design should form commodities, and the object of design is commodities. If you want to become a commodity, you must pay attention to one direction, that is, the result of design can be produced. At the same time, mass production should be fully considered in the design stage.

manufacture. At present, manufacturing in China is generally not a problem, but manufacturing engineering is a blank. There is no production engineer or workshop engineer or manufacturing engineer. There is a big problem in manufacturing, that is, product quality. The poor quality of products has a lot to do with our lack of production technicians.

3) Spatial axis

The space axis includes land, sea and sky, which is the physical space of our project.

We must carry out any engineering activities in a certain physical space. So, we need to understand the spatial axis. For example, we should consider the local natural environmental conditions for the construction of pressure vessels, such as environmental temperature, earthquake, wind load, snow load, etc.
