Should China build a Super Collider The scientific people open debate the truth the more debate sexinse

Should China build a Super Collider? The debate over the truth of the scientific character of the public debate more recently, Nobel prize winner, physicist Chen Ning Yang published an article on the WeChat public number, against China today to build super collider". Should China build the Super Collider now? Qiu Chengtong, Chen Ning Yang, director of the Institute of high energy physics, Chinese Academy of Sciences, such as the master of science and technology, scientists have recently been vocal controversy, become a hot spot of public opinion in the world, such as the Chinese Academy of Sciences, the Chinese Academy of Sciences, the Chinese Academy of Sciences, director of the Institute of high energy physics, such. In this debate, the general public is not only a glimpse of the latest advances in science, but also the direct participation of the network to discuss, this phenomenon itself reflects the progress of science and technology. A typical view of Qiu Chengtong: an important achievement of high energy Collider in fifty years and every time out, can be shocking. Chen Ning Yang: the use of Super Collider to find the supersymmetry particles, only part of the high-energy physicist’s conjecture. Wang Yifang: a five year plan to start building the Large Hadron Collider, high-energy physics is the leading international a rare opportunity. The debate focuses on two aspects: the debate can be roughly summarized into two aspects. How much does it cost to build 1 Super Collider? Chen Ning Yang said in the article, the construction of Super Collider budget not less than $20 billion, the initiative to build large high-energy Collider in China by many countries, cost sharing, "but the China share will be very considerable". He was still in this paper reviews the construction of large collider experience: in 1989 the United States began to build the largest Collider, the beginning of the budget is an estimated $3 billion, then increased several times, reached $8 billion, causing many opposition, so painfully in 1992 Congress terminated the program, wasted about $3 billion. This makes it is generally believed that made the collider is a bottomless pit. In the end how much money to spend, Wang Yifang responded that the large hadron collider project planning will be divided into two steps: the first step of Electron Positron Collider construction stage (2022-2030), the project cost about 40 billion yuan; the second step proton collider stage (2040 to 2050), the project cost in less than 100 billion yuan. If the international contribution is reduced by about 30%, the Chinese government will invest about 30 billion yuan (about $3 billion a year) and $70 billion ($7 billion) per year. Chen Ning Yang said in the text, China’s per capita GDP is less than Brazil, Mexico, there are hundreds of millions of farmers and migrant workers, as well as urgent need to address environmental protection, education, health and other issues. Construction of Super Collider, the cost is very large, to solve these problems. Wang Yifang said that from the proportion of GDP, the cost of the large collider does not exceed the 80s Beijing positive and negative electron collider. Wang Yifang believes that in the next five year plan to start building the Large Hadron Collider, high-energy physics is the leading international a rare opportunity. Confrontation 2 Super Collider research value? Chen Ning Yang said that some high-energy physicists hope to use the Super Collider found supersymmetry particles, but for many years to find supersymmetry particles, completely lost.
