What physical knowledge has China Science and Technology Museum introduced? The principle is the best.
The most striking device in the lobby on the first floor is this huge "mechanical wall".

Through the "blood vessel wall", visitors can understand the working principle of the human circulatory system.

Visitors can also experience the technical details of industrial production.

1 Lou came in and was "shocked"

The new China Science and Technology Museum is located between the Olympic Park and the Olympic Forest Park. Looking from the East Gate, the whole building is reminiscent of mondriaan's paintings. The asymmetrical geometric cutting has a sense of rhythm and order, which accords with the visual image of the Science and Technology Museum. Seen from the side of the Olympic Park, the huge glass curtain wall and the giant screen theater spherical building will leave colorful reflections on the water.

When you step into the first floor of the hall, you will immediately see a huge "mechanical wall". This wall has a sense of form. It looks like a relief with a mechanical theme, but it can move. Looking closely, it is found that the contents of the wall are not piled up at will, but several mechanical structures that can change the motion mode are deliberately selected, such as connecting rod-crankshaft mechanism, shutter mechanism, Vientiane coupling and so on. The mechanical wall is like a kind of "magnetic force", which makes people feel "sticky" when they look elsewhere, and adds to the surprise when they see the huge "spiral of life" in the hall. This glass fiber reinforced plastic sculpture shows the double helix structure of DNA with the figure of men and women holding hands, which is 47 meters high.

Although the high escalator in front of you makes people want to rush to the second floor at once, wait a minute! There are three large exhibition halls waiting for you on the first floor. The "Light of China" exhibition hall is dedicated to the display of scientific and technological achievements in ancient China. The first impression is that many restored hydraulic mechanical devices are constantly busy in the exhibition hall, and the rushing sound of water and the "dull" mechanical sound set each other off. The emphasis on "tourists do it themselves" is fully reflected in this hall, where "Luban Lock", "Nine Rings", "Washing Fish" and various ancient educational toys in China make tourists enjoy themselves. The most impressive exhibits are two kinds of "seismographs", one is the "inverted vertical pole" model restored by Mr. Wang Zhenduo, and the other is the "suspended pendulum" model restored by Mr. Feng Rui. The two poles are vertical and vertical, allowing the audience to participate in their own thinking about ancient science and technology in China. The Science Park, a toll hall on the same floor, uses colorful cartoon images to guide children to know some scientific principles. There are many ladders to climb, a lot of water to play with and a small stage for children to sing and dance. In addition, there is a temporary exhibition hall, this time showing the achievement exhibition of "Thirty Years of Youth Scientific and Technological Innovation Activities".

The second layer explores with scientists.

On the second floor, the most striking thing in Gongx * * area is three dinosaur fossils. In addition to dinosaurs, bubble imaging and dynamic deformation walls are also the highlights of public areas on the second floor. Bubble imaging relies on mechanical and electronic devices to release bubbles at appropriate times, so that bubbles form various patterns and characters in the rising process; Dynamic deformation wall uses a series of pneumatic structures to make a wall move like waves, which is very magical.

The exhibition hall on the second floor is the traditional "playing with meat" of the Science and Technology Museum-the display of basic scientific principles and interesting experiments. There are many large-scale visual effects here. Hall A mainly talks about physics and astronomy. In the exhibition hall, you can see huge crystal models and celestial models, and you can also see very Q statues of scientists' activities. Many interactive exhibits are impressive, such as "spinning golden egg", where a metal egg can keep spinning on a disk like a demon. It turns out that there is an electrified coil under the disc, which will produce a rotating magnetic field in space, and the metal egg is a closed conductor. The rotating magnetic field formed by the coil will generate current in the golden egg and form a magnetic field, which will make the golden egg rotate as if it were possessed by two phases. Exploration and discovery hall B mainly introduces mathematics, acoustics and biology, and has large-scale biological tissue models, including neuron cells, muscle cells and sperm-egg combination models. The effect is very dreamy.

How does the third layer technology change life?

The new China Science and Technology Museum conforms to the development trend of world science and technology museums, emphasizing the relationship between science and technology and human life, rather than rigidly dividing exhibition areas according to disciplines. The general title of the third-floor exhibition area is "Science and Technology and Life", which respectively introduces the science and technology in transportation machinery, agriculture, health, housing and information dissemination. This layer is the most used field of multimedia interactive technology. There is a "blood vessel wall" in the "Healthy Road" exhibition area of Hall A, and there are two bottles on the huge walking blood vessel model, which inject red liquid at different speeds to demonstrate the difference between arterial blood vessels and venous blood vessels. In order to explain the large amount of water contained in the human body, there is an interactive project in which visitors stand on an electronic scale and the computer calculates the approximate weight of water in his body. Then, visitors put the buckets on another electronic scale until they are roughly equal to the water in their own bodies. Tourists will be surprised at their "water content" so high after panting.

Hall B shows the polishing models of vacuum cleaners, range hoods, toilets and other items, clearly showing their principles. Hall C shows the application of information technology. There is a "digital water wall" here. By accurately releasing water droplets, the falling water curtain can carry various shapes or characters in the air. Another impressive project in Hall C is "Fighting Virus". Children can use exaggerated toy guns to fight viruses, worms and Trojan horses flashing on the screen. Hall d displays transportation and mechanical technology. As soon as I entered the door, I saw a model of "terminal". The panoramic view of the airport is wonderful. A hall full of models of airplanes, trains and submarines will make children who like machinery jump for joy.

The fourth layer: How do humans face the future?

I saw the exhibition hall on the third floor and experienced the great role of science and technology in human life. Visitors came to the exhibition hall on the fourth floor with the theme of "Challenge and Future". Energy technology, material technology, gene technology, space technology and marine science are the science and technology that have great influence on the future development, and the deterioration of the earth's environment is the biggest problem facing mankind. Because many new concepts are involved, designers have come up with various methods to increase understandability and interactivity. In Hall A, the huge China climate change sand table model is impressive, and the demonstration of nuclear fusion principle is very clever. Visitors need to squeeze a "baffle" on the computer screen with considerable strength, and the cartoon deuterium atoms on the screen will get closer and closer. When the critical point is reached, deuterium atoms will turn into flames, which vividly illustrates the difficulty of "high pressure induced nuclear fusion". The display of gene technology and space technology in Hall B emphasizes the contribution of China people.

The exhibition area of the new China Science and Technology Museum is about 40,000 square meters, which is 2.5 times that of the old one. Walking around in it will make people feel "weak legs". It is rare to see such a "fun" museum.

Learn about the new museum through painting.

The new China Science and Technology Museum is one of the largest science and technology museums in the world, with an area of 48,000 square meters and a construction area of 6,543.8+0.02 million square meters. The exhibition hall on the fourth floor of the new building includes five theme exhibition halls: Science Park, Light of China, Exploration and Discovery, Technology and Life, Challenge and Future. In addition, the new museum also has four special-effect cinemas, namely, the ball screen cinema, the giant screen cinema, the dynamic cinema and the 4D cinema, and there is an audience dining room in the basement.

The new China Science and Technology Museum is much bigger than the old one. It is really difficult to visit every corner of the new museum in a short time and appreciate and operate every exhibit and installation displayed here. With the help of the plan of the new museum here, let's take a look at what specific exhibitions are included in these five theme exhibition halls, and what is there to see and play in each exhibition.
