China Youth Network, Beijing, March 29 (Reporter Zhang Ruiling) Recently, the annual ceremony of "I am a Scientist" hosted by the Science and Technology Popularization Department of the China Association for Science and Technology and hosted by Guokr, "Science and You, Exploring the Connection of All Things" ended successfully at the China Science and Technology Museum. Five main lecturers and scientists on the spot were connected to each other videos, and a 92-year-old academician took the stage to do popular science. Zhang Shuangnan, the host of the main venue in Beijing, sighed on the spot: "In addition to participating in academic conferences, today's annual ceremony is the most dense event I have ever seen."

Zhang Ying, executive director and deputy chief designer of the Chang'e-4 probe project of the China Academy of Space Technology, shared the argumentation process of "going to the front more securely or going to the back" that Chang'e-4 initially faced, and also shared the technical challenges faced, such as how to achieve "fixed point, timed, and accurate" high-precision landing on the back of the moon with rugged and complex terrain and how to solve communication problems.
"We astronauts not only regard the spacecraft we develop as their own children, but also have a sense of awe of it. Master Liu, the leader of our assembly team, said, if you treat it well, it will work hard; if you fool it, it will fool you-I believe Master Liu's words, if you take this job seriously and do your best to do everything well, you will have a clear conscience and no regrets."
speaker Wang Yifang: "Why do we need a large collider". Photo provided by the organizer
Academician of the Chinese Academy of Sciences and director of the Institute of High Energy Physics, Chinese Academy of Sciences, Wang Yifang gave a speech entitled "Why We Need a Large Collider". "After human beings reach a certain level of civilization, they will begin to explore: what is the universe? What is matter?" Since the 1950s, particle physics has been independent and flourished from nuclear physics, achieving remarkable achievements, winning nearly 1/3 of the Nobel Prize in Physics. More importantly, it has taken human understanding of the universe and matter a step further. "We need to understand the problem of the particle standard model, and most of these problems are related to Higgs particles. Therefore, we need to establish a 'Higgs factory', which is the CEPC (large ring positive and negative electron collider ) for which we are working hard."
"The special nature of high-energy physics work is reflected in: concentrating 20 years of money on one device to achieve high efficiency." Wang Yifang did some calculations for everyone on the spot, explained the particularity of high-energy physics work, and compared the number, scale and scientific leadership of scientific devices in China, Europe, America and Japan. "Our future is in science and technology, and we cannot indulge in the achievements of our predecessors. We should have our own new things. Any civilized country or a developed country must ultimately contribute to human civilization and knowledge. It is our unshirkable responsibility to engage in the discovery and accumulation of knowledge and contribute to human civilization, and it is also a basic requirement and condition that will eventually be recognized and respected by everyone internationally."

Speaking of protein, many people will think of high-protein foods such as eggs, milk, chicken, duck, fish, meat and shrimp. Wang Zhizhen, a protein scientist, an academician of the Chinese Academy of Sciences, and a researcher at the Institute of Biophysics, Chinese Academy of Sciences, is more concerned about the structure of proteins.In a speech entitled "A Little-Known Scientific Story of Artificial Synthesis of Insulin", Wang Zhizhen pointed out that insulin synthesis was faced with a key problem: "Although insulin is a small protein, it is composed of two chains, with two disulfide bonds connected between the two chains, and one of the chains has a disulfide bond itself - this special structure created a bottleneck problem for the synthesis of insulin, and there is also an ambush in this bottleneck problem that was completely unclear at the time, which is the protein folding problem that I want to emphasize today." How can
make the two artificially synthesized peptide chains be linked and folded in the correct natural way to form a biologically active insulin molecule? This was a global problem at that time. However, after seven years of hard work, Chinese scientists finally artificially synthesized crystalline bovine insulin with all biological activities in 1966. "This research result reached the world's leading level at that time, and also led us to a new world of 'protein folding' in protein science," said Wang Zhizhen.
Speaker at Shanghai Branch Ye Shuhua : "I am 92 years old this year, I want to do two things." Photo provided by the organizer
"We used to follow others in science and then lead others to lead others - so, is it possible to lead others in astronomy? For example, the 500-meter-caliber telescope "Sky Eye" is indeed leading in technology, but it is not enough. I hope young comrades can do and make more truly leading things." The theme of Ye Shuhua, an academician of the Chinese Academy of Sciences and honorary director of the Shanghai Observatory of the Chinese Academy of Sciences, at the Shanghai branch venue was "I am 92 years old this year, I want to do two things." "What else can I do? I want to beat the gongs and drums for young people, shake flags and shout, and help them make some good projects that really "look like a thing" in the astronomy cause. "What are the two projects of
? "One is SKA (a square kilometer radio telescope array) coming to China to strive to be a regional center for science and data. The minimum area is China, the bigger one is Asia, and the bigger one is Asia Pacific. Now we have a very good relationship with Australia, so I think we will finally be a scientific data center for the Asia Pacific and the Asia Pacific region." The second thing to do is related to space. "For observations during the dark period of the Big Bang, low-frequency radio is needed - since it is low-frequency, why can't we go to space? Look, on the ground, we have FAST, a large-diameter telescope. I want to put two radio telescopes with a diameter of 30 meters in the space, specializing in VLBI, which is also a very important supplement to the SKA project. We want to seek to open up our boundaries in the range of medium and low frequencies." Peng Kaiping, speaker at
: "Does my ideal you really only come from the stars?" Photo provided by the organizer
In the era of artificial intelligence, do we really need to study topics like "happiness"? In the view of Peng Kaiping, Dean of the School of Social Sciences of Tsinghua University and Director of the Department of Psychology at Tsinghua University, the only intelligence we can understand is our psychological activities. In 2018, the marriage rate in China dropped to the lowest in history, "home" and "social fear"... Young people now seem to be beginning to appreciate a new way of life, and are unwilling to establish social relations and are unwilling to interact with others. At the same time, our mental health in China has also become a particularly important issue. "We cannot exist without others. Even if you are Robinson, you need a 'Friday'. Even if you are mentally ill, like Xie Xun, the Golden Lion King in "The Legend of the Condor Heroes", you need to establish a relationship with others."
entitled "My ideal you can really only come from the stars?" In his speech in 》, Peng Kaiping pointed out: People are the demanders and creators of social relations. We have extraordinary abilities and are particularly easy to establish close social relations with others. "Why is the social relationship important for people? Many studies from social psychology have proved that if people want to live a healthy and long life, happiness and happiness, they must have a beautiful intimate relationship."In addition to scientific evidence, Peng Kaiping also shared scientific communication skills on the spot. "The American social psychologist Losada proposed the famous "Losada ratio": Saying five good words, you might as well match a critical and suggestive sentence, all of which are good words. The other party must be bored, but you can't always say bad things, so you should also say some positive words - communication is also scientific. "
Starting from the first issue in July 2018, the content of "I am a Scientist" has spread over 100 million on the Internet. The speeches are packed, with 3,000 viewers coming to the speeches, and the audiences are distributed in different age groups. It is understood that in the future, the series of speeches "I am a Scientist" will continue to be held. The content platform of "I am a Scientist" will gather more scientists and scientific and technological workers to explore the path of popular science and a complete science communication system.
