4. On the first day of the summer camp, we came to the Beijing Science and Technology Museum, and the teacher gave us two hours to visit. So I visited with Yao Mengtian, whom I just met on the train
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...

"time and space tunnel" is very interesting because of my name. 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 and people walk 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 the Beijing Science and Technology Museum has added me a lot of knowledge, and I have gained a lot.

the exhibition area of the new museum is much larger than before, with about 40000 square meters, more than 800 permanent exhibitions, and most of them can be operated or experienced by the audience. There are many more things in the exhibition than before, which are more ecational and entertaining. There are many projects for children to experiment by themselves, and there are many live demonstrations and lectures of scientific knowledge, so that children can experience the wonder and charm of science with their own eyes when they visit. The exhibition contents are so rich, and they are all new exhibits representing the highest level of science and technology museums at home and abroad; The degree of interaction and participation of exhibits in the new museum is much more than that in the old museum. It's the happiest and most interesting thing for children to participate and experiment in person! After seeing the features of more than 800 permanent exhibits in the new China Science and Technology Museum, I summed up the biggest feeling of this visit: "the science and Technology Museum is a public activity place that makes people happy, makes people smart, enjoys science, enlightens wisdom and proces association."

6. I love Beijing, I love the planetarium. Let me first introce the planetarium, which is located in the south of Ximenwai street, Haidian District. Built in 1957, the main buildings are astronomical hall, lecture hall, exhibition hall, observatory, etc. The astronomical hall is a round building with a diameter of 25 meters and a capacity of 600 people. The top is hemispherical. You can watch the simulated astronomical phenomena reflected by the astronomical instrument, such as the sun, moon and stars, as if you are in the sky to travel beyond time and space; The exhibition hall held a fascinating exhibition of astronomical knowledge; The lecture hall often holds various astronomical academic exchanges and lectures on astronomical knowledge; In the silver dome of the observatory, you can also use telescopes to watch sunspots, planets and nebulae. The new planetarium started construction on the original site of the planetarium at the end of 2001, with a total construction scale of 20000 square meters. It was completed and opened in the fourth quarter of 2004. The main public open facilities are: Digital Space Theater, 3D dynamic astronomy demonstration theater, 4D dynamic cinema, astronomy exhibition hall, solar observatory, public Observatory, astronomy classroom, etc. The space theater has a capacity of 200 seats. Foreign advanced digital astronomical projection equipment is introced, which is composed of large graphics workstation and adlip laser projection equipment. It can vividly interpret the magnificent starry sky scene and the great feat of human exploration of space. The 3D and 4D dynamic astronomical theaters have 48 seats and 196 seats respectively. The demonstration function of these two theaters is a supplement and extension to the function of Space Theater. They create a strong sense of presence and shock for the audience with their strong dynamic and special audio-visual effect. The solar exhibition hall, with an exhibition area of 300 meters, mainly displays the sun and solar system. The main exhibition items include 1.8 m solar white light projection image from solar vacuum telescope; 174 mm hand drawn sunspot white light full day projection image; Bright and colorful solar spectral projection image; The CCD TV images of the solar white light, the solar chromosphere and the solar local active area. The second phase exhibition of the new museum with the theme of "happy exploration of the secrets of the universe" was officially opened to the public on July 6, 2006. The exhibition is divided into 15 exhibition areas with rich contents. The public Observatory has a built-in optical catadioptric telescope with an aperture of 40 cm. It is mainly used to meet the needs of audience and young students for astronomical observation and teaching practice

that day, I was excited, happy, surprised, happy and nervous to welcome the capital planetarium. I saw the high-rise buildings on both sides flash past my eyes. Here we are. Here we are. Here we are

the premiere is a tall glass like building. I marched into the planetarium in line. As soon as I stepped into the planetarium, I felt as if I was in the universe. I found a lot of planets

a sculpture like hemispherical shape includes the story of Mars. Through the windows, you can enjoy the fantastic and mysterious scenery of Mars. Travel on Mars with fantasy. Mars, the fourth most red planet from the sun, is 1.5 times the distance from the sun to the earth. Its diameter is 53% of the earth's, and its volume is 15% of the Earth's. Mars rotates for 24 hours and 37 minutes, slightly longer than Earth. Mars also has four seasons, 687 Earth days a year. Mars has two little moons, Phobos 1 and Phobos 2

Jupiter is the fifth largest planet in the sun. The average distance between Jupiter and the sun is 5.2 times of the average distance between the sun and the earth, and its diameter, mass and volume are the largest among the planets. Its diameter is 11 times that of the earth, its mass is 318 times that of the earth, more than the sum of the masses of other planets in the solar system, and its volume is 1300 times that of the earth. It takes only 9 hours and 6 minutes for Jupiter to rotate one cycle, which is the fastest of the major planets. It takes 119 Earth years for Jupiter to orbit the sun

Saturn is sixth from the sun. Saturn has beautiful rings. Its average distance to the sun is 9.5 times. The diameter, mass and volume of Saturn are second only to Jupiter in the planetary family. Saturn is 9.5 times the diameter of the earth; The mass is 95 times that of the earth, and the volume is 760 times that of the earth. The average density of Saturn is less than that of water. If you throw it into the sea, it will float on the water surface. Saturn spins very fast, and it will rotate once in six hours and 39 minutes. Saturn's year is 29 Earth days

Uranus is seventh from the sun. The average distance between Uranus and the sun is 19 times that between the sun and the earth. Its diameter is 4 times that of the earth, its mass is 15 times that of the earth, and its volume is 63 times that of the earth. It takes 17 hours and 14 minutes for Uranus to rotate in one cycle, which takes about 84 Earth years. In the major planetary system, the angle between the rotation axis and the orbit plane of most major planets is very large. There are at least 70 degrees to 80 degrees, but Uranus is different. Its axis of rotation is almost on the surface of the orbit

in addition to Jupiter, Mars, Saturn and Uranus, there are Pluto, Venus, Neptune and earth. I will not introce them one by one. If you come to Beijing Planetarium, don't forget to see 4D movie

located in Ximenwai street, Beijing, the planetarium is a National Natural Science Museum. It mainly publicizes and popularizes astronomy knowledge to the public through artificial star sky simulation performance, holding astronomy knowledge exhibition, editing, publishing and distributing astronomy popular science books and periodicals, organizing public astronomy observation and other forms. In addition, various popular science activities such as astronomy lectures, astronomy training, Astronomy Olympiad, knowledge competition and astronomy science and technology summer (winter) camp are regularly organized according to different levels of young students, so as to guide and cultivate students' interests and hobbies in natural science. The Beijing Planetarium has become the main position for the public, especially the young people, to carry out astronomical science popularization and ecation. Since 1995, the planetarium has been successively named as the national, municipal and district level popular science ecation base, science and peace ecation base, youth patriotism ecation base, etc., and has been awarded the honorary title of national and municipal "advanced collective of popular science" for many times

the completion and opening up of the new museum will greatly enrich the open exhibition contents and astronomy teaching means of Beijing Planetarium, and make new and greater contributions to further prospering the capital's science and technology and cultural market, promoting the development of the capital's two socialist civilizations and the overall improvement of citizens' scientific and cultural literacy. Although the visit time is very short, I still remember every place in the planetarium. I'll go again next time!

visit Beijing Science and Technology Museum
WOW! 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 a room full of "egg carvings", which are 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, with its thick body, small and inappropriate tail, and jewel like shining eyes, which seem to be full of 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 also beavers on the side who are building houses...

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...

dinosaurs are coming! 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, which make me dizzy

the science and Technology Museum has given me a lot of insight. In the future, I will get to know what I don't know! bye! Science and Technology Museum in Beijing

8. If you go to school, you can learn more comprehensive basic knowledge, which will be of great help to your work in the future. If you go directly to the factory, you can also learn it, which may be more difficult. Every factory makes some targeted procts. If you learn to play, you just say that you will do the work here. It is suggested that you go to school to learn, and then come out to find work, no matter what, It still depends on personal efforts.

9. 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<

serious and important topic,
Lei Feng! Keep up with me
assess the quantitative indicators of the science and Technology Museum, and test the rigid indicators of contemporary Lei Feng
now the requirements for recruiting personnel and selecting exhibits of the science and Technology Museum 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, process, fixture, measuring tool Theoretical calculation and analysis process, adjustment, correction, setting, calibration, maintenance, testing, future development, how to simplify into internationally competitive procts, how to do image publicity and other clear documents, and to the whole society free of charge, promote the scientific quality of the people of the whole country, and promote the national competitiveness
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
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. These materials can be provided by you to the audience on CD-ROM, allowed to be downloaded by the audience, whether they are charged, whether they are allowed to be published on the Internet, whether they are allowed to be copied and sold or exhibited, whether they are allowed to apply for invention patents, whether they are allowed to be proced and exhibited by science popularization exhibition departments at home and abroad for a fee. Visitors are welcome to put forward suggestions for modification. If there is progress significance after testing, you can improve the original exhibits by yourself< For the control part, analog computers and discrete components should be used as far as possible, followed by electronic circuits composed of general integrated circuits
for the mechanical part, the cost budget should be made in advance. The appearance and performance of CNC manufacturing center are good, and the price is bound to be high; Manual processing with electric tools is bound to be my own compensation for processing costs, long working hours, irregular, suitable for the requirements of limiting the purchase price. At the same time, it points out that at home and abroad, the market value of devices mainly manufactured by manual processing is higher than those mainly manufactured by machine tools and batch proction
I am generous enough to allow any party to use the basic design data independently proposed by me to manufacture exhibits without prior economic requirements. Moreover, if there is no accumulated fund for the sale of exhibits with a manufacturing cost of more than 5000 yuan, I will not do it. You are free to choose the manufacturer and indivial
the background of this method
because I know clearly that students in various schools can design analog circuits

10. 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, which are 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, which is divided into six theme exhibition areas, namely, the foundation of food and clothing, the road of health, the road of home, the bridge of information, the convenience of transportation and the bridge of machinery, 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 shows the affinity of science and technology, so that visitors can feel the charm of science and technology in a beautiful environment
