would rather "offend" Chinese Academy of Sciences than oppose the construction of particle colliders in China. Is this hindering the rapid development of national science? Or is there another hidden truth?
In 2020, the World Particle Physics Center unanimously approved the strategic plan for future particle development in Europe.
news has reached China, and people can't help but think of the memories of Yang Zhenning 8 years ago when he strongly opposed the development of particle collider. So? Is Yang Zhenning's doing this hindering the country's particle scientific development?
Yang Zhenning and Wang Yifang are both scientists who have made significant contributions to my country's physical science. But in 2012, the two broke out in fierce conflicts and disputes over whether the country will invest in R&D and build a particle collider. Yang Zhenning, a master of the physical sciences, who has always been rigorous and steady, slapped the table for the first time and expressed disagreement.
In the end, Yang Zhenning narrowly won by one vote, so the particle collider was put on hold.
The "thing" or noun "large collider" sounds far away from us (especially friends with poor math, physics and chemistry), and some friends may not know much about it. Simply put, it is the world's largest particle accelerator facility, and particle accelerators are used in all aspects of life.
From the most commonly used TV sets, computers, various disinfection and sterilization machines, to nuclear power engineering and nuclear science.
Therefore, building a large particle collider is an indispensable link in human progress.
2019, in the auditorium of Chinese Academy of Sciences, 97-year-old Yang Zhenning communicated with students on the stage. During the
question session, students from the Institute of High Energy Physics, Chinese Academy of Sciences raised the old story, asking Yang Zhenning why he had always insisted on opposing the construction of a large particle collider in China, and said that he and many of his classmates would engage in research in this area in the future.
Yang Zhenning was silent for a while, but still told the students that he still stick to his point of view.
The reason why he opposed it was that the particle collider had reached a bottleneck or end as early as 30 years ago, which means that the era that belonged to it was over.
Looking at the students in the audience, with confusion and shock on their faces, he continued to explain that there are probably the following reasons for disagreeing with the current investment in the development of particle colliders in China.
The first is personnel and technical issues. The current reserve of domestic physics research talents is far from enough. If there is no large amount of corresponding talent investment, it will only waste time and money. Nowadays, core technologies are in the hands of foreigners. If they only master data and do not have the ability to analyze data, they can only conduct research for foreign scientific researchers.
Instead of "feeling the stones across the river" in research, it is better to lay a solid foundation first. Only when the time is right can you achieve twice the result with half the effort.
The second is the funding issue. It is conservatively estimated that the cost of building a large particle collider and R&D is about 200 billion yuan. The United States once dug a tunnel and invested at least 2 billion US dollars, and the investment in the particle collider has cost at least more than 10 billion yuan, but the result is still in failure.
Currently, China is still a developing country in . If 200 billion yuan is impulsively invested in the research and development of particle colliders, it is not only an astronomical figure, but excessive investment will greatly reduce the funds for other research.
particle collider can be built, but we must judge the situation and can be built when it is suitable and mature. Today, China does not have that urgent demand for particle colliders. The most correct choice is to invest funds in cultivating talents and other important directions that are now or urgently needed.
The third is a matter of time. According to the research situation in other countries, it requires a lot of manpower, material resources and time costs to study the research and development of particle colliders. Europe has been researched since 1994, and has not improved significantly until now. Because this is a guess after all, even if you can successfully study it, it cannot guarantee time, and it may even be a waste of time in the end.
. At least in the short term, my country has no actual application direction. It is better to wait for other countries to invest in research first, and it is not too late to wait until it is effective.
is now investing in the research and development of particle colliders, is it a "Great Leap Forward" development of domestic science and technology? Will the country take many detours? Is it difficult for the country to "return"? I think many people cannot answer the series of questions about
.
After all, ordinary people cannot judge such a highly academic field.
We should still believe Mr. Yang’s judgment, and we can only sincerely hope that he is an old horse who is determined to plan his country with ambitions for thousands of miles!
