2. Let me talk about the advantages and disadvantages of each item. 1. CNC machine operation is simple, basically not people can start in half a month. Although there is also programming, but the programming of NC lathe and machining center is not at the same level. 2. Tired driver. Why are you tired? Because the processing time of a single process is less than 15 minutes, which is equivalent to that you have been changing parts all day. CNC lathe wins by quantity. If the machining center is a proct, the single process time will not be too long, but it depends on the long view. If you are proficient in the operation of the machining center, you can not only operate the proct processing, but also operate the mold processing. Mold processing time can be long. If the knife is good, it takes more than 4, 5 or even 10 hours to complete a process. In this way, we can see who is more tired. The Turner is standing all day. You can go to bed in the machining center Of course, it's not allowed to make procts.) 3. Consider the future. Turner, the one with the highest salary can program. But it won't be very high either. If the machining center can program, the longer the time, the higher the salary. You said the machining center that place programming is not very hard to learn, don't worry, watch every day, for a long time, I also know how. 4. As for what you said about market demand, off-season and peak season, this is not your consideration. If you are lucky, a small factory is better paid than a big one because of its good business. As for the real situation, no one can predict.
3. First of all, according to their ecation level: in this work, the minimum is to graate from junior high school, because it needs a lot of knowledge about algebra and geometry, otherwise it is very difficult to learn. If you graated from mechanical technical school, it would be better. In addition, this work is very practical. No matter in the South or in the north, you will know how long you need to learn and how much you are worth after a year's practice.
4. Yesterday we came to Beijing Science and Technology Museum for a visit. The teacher gave us two hours to visit. So I visited with my classmates
when you enter the museum, you will see a bright hall with colorful ribbons on the top, which is very beautiful. The robot, who is as tall as an alt, is playing on the piano. Although the sound is not very loud, it is very nice. There are time and space tunnel, space travel, simulated world, space shopping...
the name of "time and space tunnel" is very interesting. Time and space tunnel is a circular tube. Yao Mengtian and I passed through this terrible tunnel hand in hand. There are red, green and yellow dots all around it, which made me dizzy. People walked in it, As if to fall, the body seems to be involuntarily rotating with the surrounding walls. How interesting! Although it was only a few seconds, it made me remember deeply
then we have the sound wave to see. Yao Mengtian and I swing the rope and twist the button. I saw the rope swinging in a wavy line. Oh, that's the invisible ultrasonic wave. This time, I'm an eye opener. Later, we played a lot of projects. Seeing is better than hearing. If you have time, you'd better visit it in person
today's visit to Beijing Science and Technology Museum has made me gain a lot of knowledge.

5. Introction: Beijing Science Center is a public welfare social science popularization ecation base for young people, and a platform for the display and interaction of "green Beijing, science and Technology Beijing, and humanistic Beijing". Beijing Science Center focuses on the "present" and "future" of science and technology development, and highlights Beijing characteristics in content
registered capital: RMB 2 million
registered capital: RMB 2 million
6. The exhibition projects of China Science Popularization museum are world-class, and the design materials of the exhibits can be downloaded free of charge; If tourists dedicate and open their innovative designs and prototypes, achieve originality through expert evaluation, and have novel and distinctive ecational effects, they can return the ticket fee and give rewards at the same time. This is the great achievement of reform and opening up and the scientific outlook on development, and it should be a major practice leading the world in pioneering, innovative and unique
the following measures can fundamentally and rapidly improve the quality of the whole people, establish a rigorous scientific attitude, train manual skills, and enhance the instrial foundation. With low cost, they can completely remove the breeding soil of academic swindlers, fake science, rampant academic corruption, and economic corruption swindlers without confrontation, and strip them of their lofty and dazzling disguise, Uncover the mask of hypocrisy and deception, pierce the gorgeous fig leaf, and virtually wipe out the long-standing and meaningless traditional popular science propaganda, which wastes resources and precious youth time of teenagers. Please implement it locally
this is a strategic measure to put an end to the waste of human, material and financial resources, block the channels for demanding and accepting bribes, and build socialism more quickly, better and economically<
serious and important topic:
Lei Feng! Keep up with me
evaluate the quantitative index of science and Technology Museum, and test the rigid index of contemporary Lei Feng
it is necessary to establish a long-term mechanism of Youth Science and technology ecation and implement the means of sustainable development
this is the touchstone, this is the mirror! It is a yardstick to measure the party spirit of the Communist Party of China, an examination question to consider and test the ability to practice the scientific outlook on development, and a rigid revolutionary task of scientific socialism
now the requirements for recruiting personnel and selecting exhibits in science and technology museums are strict. We should be able to design and manufacture world-class and international leading innovative exhibitions by ourselves, and write excellent documents, including design, procurement, manufacturing, assembly, technological process, fixture, measuring tool, theoretical calculation and analysis process, adjustment, correction, setting, calibration, maintenance, testing, etc The future development, how to simplify it into a clear document of internationally competitive procts, how to do image publicity and so on, and make it public to the whole society free of charge, so as to promote the scientific quality of the people of the whole country and promote the competitiveness of the country. The public welfare nature with historical breakthrough and different repercussions
can you reach this hard target
welcome to show, we are looking forward to your coming
this is a revolutionary transformation and a milestone in the scientific outlook on development
the following requirements are put forward for the construction of the domestic science popularization exhibition hall, and the same requirements are put forward for the compilation of teaching materials, teaching experiments, graation thesis, teachers' thesis and vocational training in Colleges and universities. It should be strictly promoted and implemented as a national policy and strategy, and as a scientific outlook on development, sustainable development, and sustainable development The key is to innovate the exhibition items and make the technical data of the exhibition items completely public
to make contributions that can stand the test of history, we should have historical significance, serve the public, have courage and courage, and make full and efficient use of social resources, especially for the institutions funded by the state finance, especially for the scientific research projects funded by the state finance
Science Popularization exhibition has a large number of people (reflecting the people's thirst for science and technology, but also highlighting the lack of ecation and the lack of core significance). It is not a good thing that many enterprises proce procts of the same principle and design at a low level
the existing exhibition items have clear defects in design and manufacturing, and the damage rate is high. The demonstration and interaction can not deeply reveal the engineering and scientific essence; There is no electronic document system for visitors to download for free or at a low price for each exhibition item. It is necessary to explain in detail, especially the purchasing location and price of materials and components, the processing and debugging process of non-standard components, and the constraints in design and manufacturing. It is hoped that visitors can go back to make specific suggestions for simplification, improvement and development in the future, It is to achieve that visitors can manufacture commercial procts for sale; The manufacturers of the existing exhibits come for money and keep the design information secret, which makes the maintenance cost high and the maintenance cycle long (some of them have to be transported back for maintenance), and obviously affects the exhibition effect; We are going to provide more than 100 innovation exhibitions free of charge, which will be made by students in nearby universities. We only need to provide public transportation expenses. This is the foundation of national strategy; In particular, it should be pointed out that the experimental courses, graation theses and innovative research of undergraates and postgraates are lack of engineering and technical support, which turns the country's precious resources into garbage. Therefore, it is difficult to obtain employment, and the procts are not up to the level in the international market, which has no high-end deterrent power to developed countries
through this initiative, the replicability, verifiability, repeatability and portability of science and technology and engineering technology can be fully reflected, and the copies or unit parts of the exhibition project can be lent or leased free of charge
therefore, the ticket price is not a problem, it can also be raised. Not only the students who are studying, but also the unemployed people in the society and the technical backbones in the enterprises will come. That is to improve the quality of the people through free innovation ecation and rapid ecation of basic skills. In the exhibition hall of * * and Shenzhen high tech fair, I have introced many innovative technologies that have not yet appeared in the international market to Europe, America and Japan free of charge through various prototypes in English as a visitor*** By authorizing domestic and foreign counterparts to sell a full set of innovative exhibition items, we can still generate revenue
with the existing operation mode, the operation cost of course remains high
I have a complete information and prototype of an exhibition item delivered to * *. Anyone in the world is welcome to and improve it for free. This robot power supply mode is an engineering structure proposed from the results of mathematical analysis, which is complete in engineering application; The disadvantage is that at present, only the probability solution can be achieved, and the audience will be asked to make the pure mathematical analytical solution in the future. At present, the general mathematics research institute and the ordinary doctor of mathematics can not solve it; Two exhibitions will be submitted to the relevant departments for approval to see if they are within the confidentiality limit because they have innovative military uses
now, when college students finish the experiment class, you stop him at the door of the laboratory, borrow the experimental teaching materials from him, and ask questions about the contents of this course. As long as the questions are accurate and detailed, they can't answer them. He was still in a daze just now, and it's amazing to ask the teacher; If you want him to make experimental equipment, it's bagaru, dead dead dead. Today's school teaching instruments are purchased from the society. The original manuscript of the experimental handout is provided by the teaching instrument supplier. You can imagine the rest. To graate students, it is under the guidance of foreign original scientific and technological literature and database, the imported software system, hardware platform, moles purchased in the market, system integration of ASIC and components, science and technology fast food, and modern technology platter
the prototype that has been provided to * * free of charge is that the robot gets power from the plane, curved surface and steps with feet or wheels, so it doesn't have to carry the power battery on the back like the Japanese Honda robot; After working in Beijing Jiaotong University, a doctor majoring in robotics graated from Tsinghua University made and exhibited the robot at Shenzhen high tech fair. It also towed power cables, which was environmentally friendly and innovative. It also proposed a new method of 4WD competition**** It is the exhibition of patriotism, national defense and military, science and universal ecation; As for the basic information of the equipment that can surpass the foreign flight simulation training mole and proce controllable equipment, I have been informed that the equipment can be manufactured in the nearby enterprises. I have no knowledge of the similar equipment. It can also guide students to write invention patent application documents (University Intellectual Property courses and patent attorneys don't teach you!), All these are the hard reasons for increasing ticket prices to attract the audience
now, the students of science and engineering are all assembling the same basic parts and circuit boards in their metalworking practice and electronic component assembly practice, and they will ask the teacher to grade them and then throw them away as waste procts; Graation thesis, innovation project and so on are ugly, allowing students to download online materials for primary imitation*** I am willing to volunteer to 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 problems in maintenance, you can email me: or call me: I will reply as soon as possible, because problems in instry, equipment and instruments usually need to be disassembled, measured, observed and analyzed on site
the instrial devices and instruments made in China are basically imitated from the existing procts of developed countries, and there are some problems in simplifying the original design, such as the defect of redesign, insufficient material and so on; Therefore, the complete solution to the faults of your exhibits is often to redesign more perfect components and remanufacture parts. The original manufacturing department has many secrets, which can not be equated with the maintenance of imported equipment. For example, the aircraft maintenance company at the airport has Boeing's complete maintenance manual, which has very detailed written regulations on the analysis and treatment of various faults, As I passed by, I saw their five centimeter thick maintenance manuals lined up
I have been working hard to improve my working environment for a long time, and it will come to an end about one to two years later. Before that, if you didn't agree me to manufacture my own independently designed exhibits, I would not work for you. As for the problems you have, I can come as soon as I call, fight as soon as I come, win as soon as I swing. I don't guarantee that I can solve the problem, but I will arrive as soon as possible. If the problem is solved, I will leave a complete electronic document explaining the purchasing location of materials and parts, and the future countermeasures. I also hope you can claim the reimbursement of public transportation expenses
prepare to provide innovative exhibition items. Some basic materials can be found on CD-ROM (which has been delivered to * *), and the scope and field involved will be very broad
I agree with the way that knowledge and know-how were completely disclosed free of charge ring the cultural revolution. I think that is the most effective way to promote China's instrial base and scientific and technological level, and the highest utilization rate of social resources, which is urgently needed by China's national conditions
for research projects funded by national scientific research funds in some developed countries, some relevant information is public. For example, the basic information obtained from space exploration is public, which provides an entry point for anyone in the world to conct analysis and research. Academicians of the Chinese Academy of sciences have also signed collective signatures to make scientific research materials as public as possible
the exhibits provided by me will fully disclose all design and manufacturing data, all drawings, purchase location and price of accessories, processing method, debugging and modification process, and computer program. This information can be provided by you
the following measures can fundamentally and rapidly improve the quality of the whole people, establish a rigorous scientific attitude, train manual skills, and enhance the instrial foundation. With low cost, they can completely remove the breeding soil of academic swindlers, fake science, rampant academic corruption, and economic corruption swindlers without confrontation, and strip them of their lofty and dazzling disguise, Uncover the mask of hypocrisy and deception, pierce the gorgeous fig leaf, and virtually wipe out the long-standing and meaningless traditional popular science propaganda, which wastes resources and precious youth time of teenagers. Please implement it locally
this is a strategic measure to put an end to the waste of human, material and financial resources, block the channels for demanding and accepting bribes, and build socialism more quickly, better and economically<
serious and important topic:
Lei Feng! Keep up with me
evaluate the quantitative index of science and Technology Museum, and test the rigid index of contemporary Lei Feng
it is necessary to establish a long-term mechanism of Youth Science and technology ecation and implement the means of sustainable development
this is the touchstone, this is the mirror! It is a yardstick to measure the party spirit of the Communist Party of China, an examination question to consider and test the ability to practice the scientific outlook on development, and a rigid revolutionary task of scientific socialism
now the requirements for recruiting personnel and selecting exhibits in science and technology museums are strict. We should be able to design and manufacture world-class and international leading innovative exhibitions by ourselves, and write excellent documents, including design, procurement, manufacturing, assembly, technological process, fixture, measuring tool, theoretical calculation and analysis process, adjustment, correction, setting, calibration, maintenance, testing, etc The future development, how to simplify it into a clear document of internationally competitive procts, how to do image publicity and so on, and make it public to the whole society free of charge, so as to promote the scientific quality of the people of the whole country and promote the competitiveness of the country. The public welfare nature with historical breakthrough and different repercussions
can you reach this hard target
welcome to show, we are looking forward to your coming
this is a revolutionary transformation and a milestone in the scientific outlook on development
the following requirements are put forward for the construction of the domestic science popularization exhibition hall, and the same requirements are put forward for the compilation of teaching materials, teaching experiments, graation thesis, teachers' thesis and vocational training in Colleges and universities. It should be strictly promoted and implemented as a national policy and strategy, and as a scientific outlook on development, sustainable development, and sustainable development The key is to innovate the exhibition items and make the technical data of the exhibition items completely public
to make contributions that can stand the test of history, we should have historical significance, serve the public, have courage and courage, and make full and efficient use of social resources, especially for the institutions funded by the state finance, especially for the scientific research projects funded by the state finance
Science Popularization exhibition has a large number of people (reflecting the people's thirst for science and technology, but also highlighting the lack of ecation and the lack of core significance). It is not a good thing that many enterprises proce procts of the same principle and design at a low level
the existing exhibition items have clear defects in design and manufacturing, and the damage rate is high. The demonstration and interaction can not deeply reveal the engineering and scientific essence; There is no electronic document system for visitors to download for free or at a low price for each exhibition item. It is necessary to explain in detail, especially the purchasing location and price of materials and components, the processing and debugging process of non-standard components, and the constraints in design and manufacturing. It is hoped that visitors can go back to make specific suggestions for simplification, improvement and development in the future, It is to achieve that visitors can manufacture commercial procts for sale; The manufacturers of the existing exhibits come for money and keep the design information secret, which makes the maintenance cost high and the maintenance cycle long (some of them have to be transported back for maintenance), and obviously affects the exhibition effect; We are going to provide more than 100 innovation exhibitions free of charge, which will be made by students in nearby universities. We only need to provide public transportation expenses. This is the foundation of national strategy; In particular, it should be pointed out that the experimental courses, graation theses and innovative research of undergraates and postgraates are lack of engineering and technical support, which turns the country's precious resources into garbage. Therefore, it is difficult to obtain employment, and the procts are not up to the level in the international market, which has no high-end deterrent power to developed countries
through this initiative, the replicability, verifiability, repeatability and portability of science and technology and engineering technology can be fully reflected, and the copies or unit parts of the exhibition project can be lent or leased free of charge
therefore, the ticket price is not a problem, it can also be raised. Not only the students who are studying, but also the unemployed people in the society and the technical backbones in the enterprises will come. That is to improve the quality of the people through free innovation ecation and rapid ecation of basic skills. In the exhibition hall of * * and Shenzhen high tech fair, I have introced many innovative technologies that have not yet appeared in the international market to Europe, America and Japan free of charge through various prototypes in English as a visitor*** By authorizing domestic and foreign counterparts to sell a full set of innovative exhibition items, we can still generate revenue
with the existing operation mode, the operation cost of course remains high
I have a complete information and prototype of an exhibition item delivered to * *. Anyone in the world is welcome to and improve it for free. This robot power supply mode is an engineering structure proposed from the results of mathematical analysis, which is complete in engineering application; The disadvantage is that at present, only the probability solution can be achieved, and the audience will be asked to make the pure mathematical analytical solution in the future. At present, the general mathematics research institute and the ordinary doctor of mathematics can not solve it; Two exhibitions will be submitted to the relevant departments for approval to see if they are within the confidentiality limit because they have innovative military uses
now, when college students finish the experiment class, you stop him at the door of the laboratory, borrow the experimental teaching materials from him, and ask questions about the contents of this course. As long as the questions are accurate and detailed, they can't answer them. He was still in a daze just now, and it's amazing to ask the teacher; If you want him to make experimental equipment, it's bagaru, dead dead dead. Today's school teaching instruments are purchased from the society. The original manuscript of the experimental handout is provided by the teaching instrument supplier. You can imagine the rest.

7. The newly completed China Science and Technology Museum, which looks like a giant magic cube, is located in the central area of Beijing's National Olympic Park. The new museum is a modern and comprehensive national science and technology museum with international advanced level. It is divided into five theme exhibition halls, namely "Science Park", "light of China", "exploration and discovery", "technology and life" and "challenge and future". It has four special effects theaters, including space theater, giant screen cinema, dynamic cinema and 4D cinema, It also has a number of auxiliary facilities such as laboratories, classrooms, science popularization report hall and multi-function hall, and will set up a digital science and Technology Museum. The first floor of the new museum is the place with the most "large" exhibits. Entering from the east gate, visitors will see the science corridor, a complex mechanical device composed of various gears, connecting rods, cylinders, pistons, etc; Entering from the south gate, it is the world's largest indoor sculpture "life spiral" with a height of 47 meters... As the only popular science exhibition in China that comprehensively introces ancient Chinese science and technology, the Huaxia light exhibition hall on the first floor of the new hall gives people the first impression of "pride". Huaxia light exhibition hall is the only exhibition hall in China that comprehensively introces the achievements of ancient Chinese science and technology. The exhibition hall covers an area of 2300 square meters. Compared with the old hall, it not only doubles the area, but also has a great breakthrough in the form of expression. Basically, all the exhibits are dynamic, playable and performable, greatly improving the interactivity and interest of the exhibits. The whole exhibition skillfully uses various advanced display means and information technology to transform ancient scientific and technological relics and literature records into movable models and interactive exhibits, so that the audience can understand the structure and principle of ancient inventions in their own experience and operation. The layout of the exhibition hall also strives to return to the ancients and seek truth. The Taosi Ancient Observatory, hydraulic spinning machine and other characteristic exhibits can let the audience experience the great creation of the sages and understand the structure and principle of ancient inventions. The huge structure of the pedal water wheel completely and truly reproces the process of manual water drawing. The children all rush to sit on it and experience the fun of pedal water drawing! The theme exhibition hall of exploration and discovery on the second floor of the new museum is divided into two halls A and B, with a total of 166 items and 220 exhibits. It is divided into eight exhibition areas: the wonder of the universe, the wonder of matter, the law of motion, and the rhyme of sound. Dialogue with "Mendeleev" to show the discovery process of periodic law of elements; Design a small ball sports route of "small ball travel record"; Swing can also learn knowledge of the "resonance swing"... A variety of manifestations of the combination of exhibits full of basic principles of science. Among the exhibition items of experience, the exhibition item "finding yourself" connected by comprehensive multidisciplinary high-tech biometric technology impresses the visitors most. The exhibition uses mechanical interaction, video demonstration, phantom imaging and other forms of expression, builds the exhibition framework around several important directions of scientific exploration, designs the exhibition items according to the principle of "questions are more important than answers, processes are more important than results, and methods are more important than knowledge", and uses a combination of various exhibition means to create a scientific practice scene of exploration and discovery. By making people feel the epic shock in the process of human exploration of nature and enlightening the scientific spirit, visitors can enjoy the happiness and inspiration in the process of exploration by integrating into the experience of scientific practice. The technology and life exhibition hall is located on the third floor of the new hall. It is divided into six theme exhibition areas: Food and clothing, health Road, home road, information bridge, convenient transportation and mechanical bridge, with about 300 exhibits. The exhibition hall takes the basic necessities of people's life as the core thread of the whole theme exhibition hall, and combines with diversified, situational and artistic exhibition forms to spread the concept of science and technology people-oriented. It not only pays attention to the great improvement of social life brought by the development of science and technology, but also shows the exploration and efforts made by people to cope with common challenges, Let the visitors think and comprehend in the visit and experience, and feel the well-being and benefits brought by scientific and technological innovation. The challenge and future exhibition hall is located on the fourth floor of the new hall, which is divided into seven exhibition areas, including earth story, energy world, ocean development and space exploration, with a total of 138 items. Based on the clue of "challenge solution future", the exhibition hall draws people's attention to sustainable development with the major challenges facing the world, and encourages the public to actively respond to the challenges and create a harmonious future through the overall structure and consistent display from challenge to future. For example, through the large-scale three-dimensional sand table, visitors can intuitively see the changes brought about by climate change in China. The five permanent theme exhibition halls are exquisitely designed, vivid and flexible, and the public space exhibition halls scattered on each floor of the new hall are also wonderful. Centering on the exhibition theme of "beauty of innovation and harmony", the exhibition hall and the permanent exhibition hall are "harmonious but different", which echo each other and form their own system. The establishment of large-scale exhibits such as small ball array, life spiral, mechanical melody, bubble imaging and time wheel will show the affinity of science and technology, and let visitors feel the charm of science and technology in a beautiful environment. Visit Beijing Science and Technology Museum! Under the scorching sun and the scorching heat, we came to the museum like Beijing Science and Technology Museum. As soon as I went in, I felt as if I was in a big cinema without seats, so broad and cool. Each of the four white walls has a "hole", one is the gate, two are dinosaur bones exhibition, one is the corridor leading to the next room. There is also an antique clock on it, which is very beautiful. I found a staircase leading to the second floor, and found a room full of "egg carving", which is carved on the eggshell. I was surprised how people carved the pattern on the eggshell and made sure it didn't break? What attracts me most is the two dragon and Phoenix sculptures. The dragon is very lifelike. It comes in the clouds and goes in the fog, as if it is really puffing clouds; The Phoenix, with its slender tail feathers, is of extraordinary beauty. It is more gorgeous than a peacock, purer than an egret, more delicate than a hummingbird, and more noble than a canary. It flies around in the misty fog, and it is extremely beautiful. There are also animal statues, a rhinoceros standing on the road at the door, its thick body, small and inappropriate tail, and jewel like shining eyes, which seem to be suffused with tears; Next to the rhinoceros, several "big" mice are staring at it with small eyes, showing two front teeth. They seem to envy its huge body. In the most corner, a goat hides behind a stone, revealing a head, which is very lovely. On the side of the glass frame, there is a Weasel, yellow hair, with a small tail, a look of fear; There are beavers who are building houses on the side... Walking forward, I found an insect exhibition area with many insect specimens. There are many butterflies in the specimen, and the one I like most is the goddess of light. Its wings are shining under the lamp with a faint blue light, which has a unique beauty. There are many other insects: stick beetles, beetles, ladybugs, farters, fruit flies... Here comes the dinosaur! It may not have been common in the Cretaceous period, but now it's great to see a living dinosaur. Walking into the dinosaur exhibition area, there are dinosaur bones everywhere, showing us the glory of dinosaurs in the past. There are also simulated dinosaurs, which look terrible, but you can't touch them with your hand. There is a fake dinosaur foot in the corner, and there are many real dinosaur egg fossils in the second layer. One by one, as if the little dinosaurs would climb out at any time. There are many things we often contact in the Botanical Museum, such as corn, apples, wheat seedlings and so on. The science and Technology Museum has given me a lot of insight. In the future, I will get to know more about what I don't know! bye! Science and Technology Museum in Beijing
8. The China Science and Technology Museum is divided into four floors. Because there are too many visitors, we went to the exhibition hall on the second floor - Exploration and discovery
exploring and discovering this exhibition hall is the most peculiar. As soon as I got in, I was fascinated by little ball's travels. Ball travels is to put a ball into a machine, let it rise, fall, circle, hit metal, launch "sky". Further on, I saw a game - fingers push the building, how can fingers push the building down? I take this question to take a closer look, only to know that this is the famous domino: let the finger push down a small square, and then let the small square push down the big square... Until finally use the super large square to push down the building! I had a good time. Seeing that there were still many things I didn't visit, I left reluctantly
next, we watched the airflow shooting - blowing the hollow ball into the basket with air, space roaming - sitting in a simulated spaceship and looking at the stars with an astronomical telescope... This museum is really big. I am dazzled by all kinds of modern devices, and I want to try every one. These high-tech procts have aroused my enthusiasm for science. I still have a lot of knowledge to learn! After watching it on the second floor, we came to the exhibition hall on the third floor - technology and life
on the third floor, there is a huge bicycle, the propeller. The screw propeller is a bicycle with a big propeller behind it. At first, it was very hard, but later, it became faster and faster because of the recoil force. But you don't have to worry about falling, because the bike is fixed and can only go around in circles
the science and Technology Museum has given me a lot of insight. In the future, I will get to know more about what I don't know! bye! Science and Technology Museum in Beijing
