Xinhua Shanghai, May 28 (Reporter Ji Shaoting, Xu Xiaoqing, Tian Ye) China, which has nearly 100 large and small science and technology museums, showed the world the largest "science and technology museum" - the Shanghai World Expo Park in 2010. The World Expo, held for the first time in a developing country, has become a technological feast related to the "present" and "future".

This 3.28 square kilometer park accommodates designs and concepts from 246 countries and international organizations, and shines with the wisdom of humanity in exploring the world through technology.

Robots, concept vehicles, aircraft, earthquake resistant buildings, and the Expo Park include cutting-edge technology from around the world. The host country's "one axis and four pavilions", as well as novel buildings from various countries, are also a showcase for environmental protection and high technology. Walking around the Expo Park, visitors may also meet Yang Fujia, Ye Shuhua, academicians of the CAS Member, Guy Laval, academicians of the French Academy of Sciences

In the past month, more than 6 million Chinese and foreign visitors have visited the "Science and Technology Museum". This "science and technology museum" not only inspires people's curiosity, but also serves as a "key" to try to open up a better urban life in the future.

"Amazing!" The 1.23-ton "Big Magic Ball" in the German Pavilion swayed in the midst of people's exclamations, suddenly "turning into" a suspended "eyeball", gazing at the loudest area of the crowd.

"Why can a metal ball without eyes and ears interact with the audience? It's incredible," said Wang Ying, a Shanghai tourist.

Faced with this metal ball with 400000 light emitting diodes, the Chinese people also lowered their reserve and shouted loudly. The secret of the ball is actually that on the ceiling of the hall, there are eight microphones installed to listen to the audience shouting from eight directions, and a computer is responsible for processing these sounds, controlling the ball to swing or change patterns

Ing Kasco, project manager of Germany's Mira Joint Design and Planning Co., Ltd., which is involved in the development of the "Power Source" metal ball, said that the technology related to this ball is not mysterious, but few people use these technologies to make such a "fun thing.". The ultimate hope of interactive activities is to express "the unity of humanity can generate tremendous power.".

There are many cases of "using technology to create novelty" like the German Pavilion, such as the giant screen high-definition projection in the Saudi Pavilion, and the robot playing the violin in the Japanese Pavilion. According to a statistic, nearly a month after the opening of the Shanghai World Expo, the exhibition hall with the longest average queuing time is almost also the exhibition hall with the highest technological content.

Wang Xiaoming, curator of the Shanghai Science and Technology Museum, said, "The role of the Science and Technology Museum lies in teaching and entertainment. From this point of view, many functions of the Expo Park are very similar to those of the Science and Technology Museum, and people can experience the novelty and joy brought by technology within the Expo Park." He said that compared to ordinary science and technology museums, the Shanghai World Expo Park is more of a science and technology feast, with exhibits from around the world far exceeding the content that a single city can provide.

The multimedia version of "On the River during the Qingming Festival" at the China National Pavilion is a product of the combination of high-tech and traditional Chinese culture. It gives technology a sense of beauty and presents a vivid picture of ancient Chinese urban life. On the 128 meter long "wall", an enlarged "Picture of the River during the Qingming Festival" is displayed, with thousands of characters moving lifelike as the day and night scenes alternate.

Wang Jiang, a Shaanxi tourist, said, "I didn't expect this painting to be displayed in this way. The cold technology in the past imagination has become amazing.".

In Area D, where enterprise pavilions abound, technology is closely linked to people's clothing, food, housing, and transportation. SAIC-General Motors Pavilion focuses on "line", and its concept car "leaf" is not only designed as a streamlined green leaf, but also powered entirely by solar and wind energy.

Yuanda Pavilion focuses on "living", and its exhibition hall itself is a "breathing" energy-saving building. This building combines the characteristics of "9 degree earthquake resistance, 6 times material saving, 5 times energy saving, 1% construction waste, and 100% factory manufacturing", becoming a "sustainable building" with high technological content.

The "furry" British pavilion across the river from the Grand Hall is a "seed palace.". The more than 60000 acrylic rods that have built the British Pavilion contain various seeds. The pavilion also shows people the infinite imagination of British scientists about "future plants" - plants that can eat themselves and turn into oil, plants that can catch thieves, plants that can send mobile phone messages, plants that can isolate noise, and plants that can identify viruses in the air... These "future plants" that have not yet become reality are thought-provoking.

Yan Feng, editor in chief of the well-known Chinese science and humanities magazine "New Discovery" and professor of Chinese at Fudan University, believes that the technology displayed at the Expo is not only about the present, but also about the future. He said, "Science and technology should be a combination of ideals and practicality. It should not only be closely related to clothing, food, housing, and transportation, but also give humanity a hope.".
