About us China in the modern development is very rapid already, we only spent a few decades, from the reform and opening up, our level of development has surpassed the world's many developed countries in the world at the forefront of the world's second largest economy, it is not difficult to see China's speed of development is how fast, which is attributed to some of the scientific and technological development and a variety of policies in China. This is due to some of China's scientific and technological development and a variety of policy coordination. There are some great scientists who have contributed to this, such as the Chinese scientist Yang Zhenning. However, Yang Zhenning is against the construction of colliders in China, what is the use of colliders? The answer to this is mainly the following.
I, building a collider now a technology is not mature.First of all, the first point is that the construction of a collider is now a scientific and technological requirements are very high, but now there is no country in the world can complete the establishment of a large-scale collider, including the United States of America is also so. But our country with such scientific and technological and economic strength, but build a belong to our country's independent research and development of the collider, it is not difficult to see our country's strength to enhance exactly how big. And Yang Zhenning opposed, precisely because he did not want the country to shift the economic center of gravity to a research field without any scientific significance.
Two, the impactor can help us study the development of the quantum field.Secondly, the other point is that the collider can help us study the development of the quantum field, after all, in our country in the development of the quantum field, compared to other countries, has been in a more backward situation, ah, the construction of the collider can be realized in such a situation to bend the road.
Third, this is from Yang's personal point of view to consider.The last point is from Yang Zhenning's personal point of view to consider because, in fact, he does not want China to put more energy into the quantum field of a research, because he hoped that the country will be able to put the center of the research radiated to more areas, such as aerospace, bio-engineering, etc., which are China's weaknesses.
