Brief introduction of the new Beijing Science and Technology Museum

The exhibition projects of China Science Popularization Museum are world-class, and the design materials of the exhibits can be downloaded for free; Visitors who contribute and openly innovate designs and prototypes, and achieve originality through expert evaluation, and have novel and distinctive educational effects, can refund the ticket fees and give rewards at the same time. This is the great achievement of reform and opening up and Scientific Outlook on Development, and it is a pioneering, innovative and unique practice leading the world.

The following measures can fundamentally and rapidly improve the quality of the whole people, establish a rigorous scientific attitude, train and exercise manual skills, strengthen the industrial base, and cost little. Without confrontation, the breeding ground of academic swindlers, pseudo-science, rampant academic corruption and economic corruption fraudsters will be completely cleared, their lofty and dazzling camouflage will be stripped, false masks and scams will be uncovered, and gorgeous fig leaf will be punctured, which will be invisible and wasteful.

this is a strategic measure to put an end to the waste of manpower, material resources and financial resources, to block the channels for soliciting and accepting bribes, and to build socialism quickly, economically and efficiently.

serious and important topic:

Lei Feng! Look at me! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

Check the quantitative indicators of the Science and Technology Museum and test the rigid indicators of contemporary Lei Feng!

It is necessary to make it universal, routine, standardized and institutionalized throughout the country, establish a long-term mechanism for youth science and technology education and implement the means of sustainable development.

this is the touchstone, and this is the magic mirror! It is a yardstick to measure the principle of China's Party spirit, an examination question to consider and test Scientific Outlook on Development's ability to practice, and a rigid revolutionary task of scientific socialism.

Now, there are strict requirements for recruiting science and technology museum personnel and selecting exhibits. We should be able to design and manufacture world-class and internationally leading innovative exhibits by ourselves, and we should write excellent documents to simplify the design, procurement, manufacturing, assembly, technological process, fixture, measuring tool, theoretical calculation and analysis process, adjustment, correction, setting, calibration, maintenance, testing, future development and how to simplify it into international. The public welfare nature with historical breakthrough and different repercussions.

can you reach this hard target?

welcome to show us, and we look forward to your arrival!

This is a revolutionary and thoroughly remoulding change, which is a landmark change in Scientific Outlook on Development.

The following requirements are put forward for the construction of domestic science popularization exhibition halls, and the same requirements are put forward for the compilation of teaching materials, teaching experiments, graduation thesis, teachers' thesis and vocational training in colleges and universities, which should be strictly promoted and implemented as a national policy and strategy, and serve as a rigid index for quantitative assessment of Scientific Outlook on Development, sustainable development and full utilization of social resources:

The key is that the exhibition items should be innovative and the technical information of the exhibition items should be fully disclosed.

To make a contribution that can stand the test of history, it must be of historical significance, serve the public, have courage and courage, and make full and efficient use of social resources, especially for institutions funded by the state financial allocation, especially for scientific research projects funded by the state financial allocation.

It is not a good thing that there are a large number of people in the science popularization exhibition (reflecting the people's thirst for science and technology, but also highlighting the lack of education and core meaning), and many enterprises with the same principle and design repeatedly produce products at a low level.

The existing exhibits have definite defects in design and manufacture, and the damage rate is high, so the demonstration and interaction can't profoundly reveal their engineering and scientific essence; There is no electronic document system for visitors to download for free or at a low price for each exhibition. In particular, it is necessary to fully and publicly introduce the purchasing place and price of materials and components, the processing process and debugging process of non-standard parts, and the constraints imposed on design and manufacturing. I hope visitors will go back to simplify, improve and develop in the future, that is, to achieve the goal that visitors can manufacture commercial products for sale; The manufacturers of existing exhibits all come for money and keep the design information confidential, which leads to high maintenance cost and long maintenance cycle (some of them have to be shipped back for maintenance), which obviously affects the exhibition effect; We are going to provide more than 1 innovative exhibitions for free, which will be made by students from nearby universities, and only need to provide public transportation expenses. This is the national strategy, the foundation of the country; In particular, it should be pointed out that the experimental courses, graduation theses and innovative research of undergraduate and graduate students at present all lack the support of engineering technology, which turns the country's precious resources into garbage, so it is difficult to find employment, and the products can't go up in the international market, which has no high-end deterrent to developed countries.

through this measure, the replicability, verifiability, repeatability and portability of science and technology and engineering technology can be fully reflected, and the replicas or unit parts of the exhibited projects can be lent or leased free of charge.

In this way, the ticket price is not a problem, but can be increased. Not only students who are studying, but also people who are unemployed in society and technical backbones in enterprises will come, that is, to improve the quality of the people through free innovative education and rapid education of basic skills. I have introduced many innovative technologies that have not yet appeared in the international market to Europe, America and Japan in English as a visitor in the exhibition hall of * * and Shenzhen Hi-Tech Fair. * * * You can also generate income by authorizing your peers at home and abroad to sell a full set of innovative exhibits.

with the existing operation mode, the operation cost is of course high.

I already have complete information of an exhibition and the prototype has been delivered to * * * *. Anyone in the world is welcome to copy and improve it for free. This robot power supply method is an engineering structure proposed from the results of mathematical analysis, which is complete in engineering application; The disadvantage is that only the probability solution can be achieved at present, and the audience is invited to make an analytical solution of pure mathematics in the future, which can not be solved by ordinary mathematics research institutes and ordinary mathematics doctors at present; Two exhibitions will be submitted to the relevant departments for review to see if they are within the confidentiality restrictions, because they have innovative military applications.

Now, when a college student finishes an experimental class, you block him at the entrance of the laboratory, borrow experimental teaching materials from him, and ask questions about the content of this tutorial. As long as the questions are accurate and detailed, they can't guarantee that they can't answer them. He was just puzzled, and he was dumbfounded when he asked the teacher. If you want him to make experimental equipment, it's bageyalu, and there's nothing you can do about it. Nowadays, school teaching instruments are all purchased from the society. The manuscript of the experimental handout is provided by the teaching instrument supplier, and the rest can be imagined. The graduate students are imported software systems, hardware platforms, modules purchased in the market, system integration of application-specific integrated circuits and components, science and technology fast food and modern technology platter under the guidance of original foreign scientific and technological documents and databases.

The prototype that has been provided to * * * for free now is that the robot gets power from the plane, curved surface and steps with its feet or wheels, so it is not necessary to carry the power battery on its back like Honda robot in Japan. The robot manufactured by the doctor of robotics who graduated from Tsinghua University after working in Beijing Jiaotong University and exhibited at Shenzhen Hi-Tech Fair is also towing the power supply cable, which is environmentally friendly and innovative, and also puts forward a new method of four-wheel drive competition. * * * * is the exhibition of patriotism, national defense and military affairs, and science popularization education; As for the basic information of the equipment that can generate controllable * * * beyond the foreign flight simulation training cabin, it has been notified to * * *, and the nearby enterprises can manufacture it. With my ignorance, I have not seen similar devices. You can also guide students to write application documents for invention patents (intellectual property courses in universities and patent attorneys don't teach you! ), all these are the last word to increase the ticket price to attract the audience.

At present, the metalworking practice and electronic component assembly practice of science and engineering students are all about assembling the same basic parts and circuit boards. After completion, please ask the teacher to grade them and throw them away as waste. Graduation thesis, innovative projects and so on are ugly and unsightly, allowing students to download online materials for primary imitation; * * * In * *, we should provide practical topics for the next generation of the motherland and make full use of students' experimental and teaching funds. I am willing to voluntarily guide them to create various innovative exhibitions and guide them to cross the threshold of book content and market contact and participate in social competition.

If you have any maintenance problems, you can email me, or call, and I will give you an answer as soon as possible, because industrial, equipment and instrument problems usually need to be disassembled, measured, observed and analyzed on site.

The industrial devices and instruments made in China are basically imitated from the existing products in developed countries, but there are some problems in simplifying the original design, such as redesign defects and insufficient materials. Therefore, to completely solve the faults of your exhibits, it is often necessary to redesign more perfect parts and re-manufacture parts. The original manufacturing department has a lot of confidentiality, so it cannot be equated with the maintenance of imported equipment. For example, the aircraft maintenance company at the airport has a complete maintenance manual of Boeing, and there are very detailed written regulations on the analysis and handling of various faults. I saw their maintenance manuals with a thickness of 5 cm prepared in rows.

I have been working hard to improve my working environment for a long time, and it will take about one year to two years to come to an end. Before that, I won't work with you for the time being unless you agree to make my own independently designed exhibits. As for any difficult problems you have, I can come at the call, fight when I come, win when I fight, and go away when I linger. There is no guarantee that I can solve the problem, and I will arrive as soon as possible. If the problem is solved, I will leave a complete electronic document explaining the purchasing place of materials and parts and the future countermeasures. I also hope that you can reimburse the transportation expenses to and from the company.

prepare to provide innovative exhibits. Please refer to the CD-ROM (delivered to * * *) for some basic materials, which will cover a wide range and field.

I agree with the way that knowledge and know-how were completely disclosed free of charge during the Cultural Revolution, and think that it is the most effective way to promote the industrial base and scientific and technological level of China, and the highest utilization rate of social resources, which is urgently needed by China's national conditions.

In some developed countries, some related materials are made public for research projects funded by national scientific research funds. For example, the basic information obtained from space exploration is made public, which provides an introduction for anyone in the world to analyze and study. Academicians of China Academy of Sciences have also collectively signed to disclose scientific research materials as much as possible.

the exhibits provided by me will fully disclose all design and manufacturing materials, all drawings, purchasing places and prices of accessories, processing methods, debugging and modification processes and computer programs. You can provide the audience with CDs and allow them to download these materials. It is up to you to decide whether to charge, whether to allow them to be published online, whether to allow others to copy the exhibits and then sell or display them, whether to apply for invention patents, and whether to license the domestic and foreign science popularization exhibition departments to produce and display them with compensation. The audience is welcome to put forward suggestions for revision. If it is meaningful to make progress after testing, you can improve the original exhibits by yourself.

For young and low-educated audiences, they can't understand the contents of the CD at present. With the growth of age, experience, education and experience, they will gradually deepen their understanding after entering a higher school and working. In any case, it is better than the effect of the current tour. The further development is to use electronic documents to answer the audience's special questions, create exhibition items for the audience's special requirements, provide applied technical services for enterprises, solve technical problems, and continue to implement the principle of completely open answers. It can also provide the audience with a practical environment for personally manufacturing exhibition projects.

For the control part, analog computers and discrete components are used as much as possible, followed by electronic circuits composed of general integrated circuits.

For the mechanical part, the cost budget should be made in advance, and the appearance and performance of the CNC machining center are good, and the price is bound to be high; Hand-machining with electric tools is bound to pay for the machining cost, and the working hours are long and irregular, which is suitable for limiting the purchase price. At the same time, it is pointed out that at home and abroad, the market value of devices mainly manufactured by hand-machining is higher than that of devices mainly manufactured by machine tools and mass production.

I am generous enough to allow anyone to use the basic design materials independently proposed by me to make exhibits without prior economic requirements. Moreover, for the exhibits with manufacturing cost higher than 5 yuan, I will not do it without the accumulated funds for selling the exhibits, and you are free to choose the manufacturing units and individuals.

The background of putting forward this method

Because I clearly know that students in various schools today have low analog circuit design ability, that is, some students can compile general computer programs. From analog circuit to high frequency circuit, you can imitate it without giving the circuit; Taking medical electronic instruments as an example, imported instruments mainly use discrete components for the front part of signal processing, and the performance can not reach the original level according to the original circuit in China, which is the embodiment of not deeply understanding the basic electronic circuit.

As long as the undergraduate students can't debug it, so can the graduate students. The solution is to adopt application-specific integrated circuits, adopt imported complete machines and integrate the systems.

Based on my personal observation at the site of * * during the Cultural Revolution, * * * * Factory made its own mechanical feeding device for punching machine controlled by jet logic, its own lathe and planer, its own semi-automatic lathe, and its own wire cutting machine, all of which actually played a role in production. The technical support was that the drawings at that time were completely exchanged in China for free, and the design drawings were copied between industries for free. At that time, unified design, great cooperation, collective research, great cooperation and a game of chess were fashionable throughout the country.

nowadays, under the national scientific research system, we block each other and beggar our neighbors. We are all enemies, intrigue and intrigue, and all work units are hostile, confidential and blocked. As far as China's industrial base is concerned, under the market competition, from daily necessities to industrial equipment, spare parts are not universal and interchangeable; The strict confidentiality of design drawings has brought great difficulties to maintenance; As a result, the production molds of the same functional products in various enterprises are repeated in large quantities, and the spare parts warehouses in the production, logistics, sales and maintenance industries have a large storage capacity; The result is that daily necessities and equipment are scrapped quickly and social resources are wasted greatly.

The state has invested huge funds in education and scientific research in scientific research institutes and institutions of higher learning, but the phenomenon of low-level repeated research is common, and the innovative designs of students in school are basically useless. Students will know the download route on the Internet, science and technology books can't directly guide the basic design, and teachers themselves are at a loss. Individual enterprises with strong production and design capabilities aim at market share, do not disclose technical know-how, and do not pose a technical threat to advanced foreign products.

Therefore, it is very necessary to make the technical key of combining basic education with production practice public to the society free of charge. As long as it is not related to the frontier in this field and directly related to military technology, it is necessary to improve the scientific quality of the whole people. This is a strategic vision and decision.

the ancients said: if you take the method, you will only get the middle. It is too difficult for domestic engineers and technicians to lead the world trend of science and technology. They are still at a loss to catch up with the world's advanced water.
