▲ Liu Jiaqi, academician of the Chinese Academy of Sciences, gave a lecture in the "opening lecture of academicians". (picture provided by the interviewee) Xiao Xu is a junior majoring in geology in a university in Beijing. At noon the other day, he took back the takeout, opened the mobile phone bracket and prepared to have lunch while watching a short video. After a while, he saw an online lecture on the subject "Daniel" and opened it with great interest. While eating and watching, more than 50 minutes are fleeting Recently, there are many netizens who have similar experience with Xiao Xu. We found that we can often see the lectures of "science and innovation China · academician's opening lecture" on the short video platform. The videos are full of academicians of the Chinese Academy of Sciences and the Chinese Academy of Engineering: academician Xu Zhilei, 91, and China's first batch of strategic weapons research experts; Academician Liu Jiaqi, 80, has traveled to the Qinghai Tibet plateau for seven times, the north pole for three times and the south pole for two times, with footprints all over the world; Mao Ming, academician of the Chinese Academy of Sciences, won two first prizes of national scientific and technological progress and led the development of the world's leading 99A main battle tank After many netizens clicked in with a "try it" mentality, they actually listened with interest, "I didn't expect to be able to take academician's classes in this life", "it's really promising, and the academician's classes were understood". Some netizens are still intoxicated after listening to one, and "urge change" the next issue in the comment area. According to statistics, since the first issue of the content went online on October 29 last year, the total viewing volume of the six programs of "Kechuang China academician's lecture" has exceeded 30 million. While setting off a wave of popular science craze, this program also makes more and more netizens become "knowledge powder" of academicians. Academicians' stories are "burning" and "warm" Liu Jiaqi, academician of the Chinese Academy of Sciences, is a famous geologist of volcanic geology and Quaternary Geology in China. He often laughs that he is a "post-80s generation". In his speech, Liu Jiaqi particularly stressed that geology, which seems to be popular, is actually closely related to popular disciplines such as aerospace engineering. "In the past, some astronauts were unconvinced and said that the spaceship went to heaven. Do you need to learn geology to command? I said, we don't care about going to heaven, but we have to take care of what the sky does, such as where to fall, what samples to take after falling, and how to take them. These are all our business. Many samples brought back from the moon are analyzed by us." Last November, Liu Jiaqi joked in a "Academician's lecture". Liu Jiaqi once visited and inspected more than 60 countries and regions in Changbai Mountain, the Qinghai Tibet Plateau in seven, the Arctic in three and the Antarctic in two. He took the lead in finding out the temporal and spatial distribution and rock geochemical characteristics of volcanoes in China, making the research on the law of Cenozoic volcanic activity in China reach the international level. He encouraged young people with his practical experience: in the most precious years of life, we should cherish time and make special achievements. Don't wait for a lot of things to be done later. It's too late to wait. Academician Xu Zhilei has been involved in the research of "two bombs and one satellite" since 1963, and has a glorious past and honor. He sat in front of the camera and talked with the majority of netizens about "subversive innovation". He understood that innovation is to subvert the tradition. This "subversion" lies not only in the replacement of technology, but also in "paying attention to human value". At the end of the program, he also thought about the problem of "staying up late" of young people: the secret of maintaining enthusiasm is to ensure good eating and sleep in daily life. If there is no enough sleep, he will not have a good ability to think. "China's amphibious fighting vehicle is the fastest in the world!" Mao Ming on the podium was full of pride. Mao Ming, an academician of the Chinese Academy of Sciences, is plainly dressed and has gray hair. On October 26th, academician Mao said that it was crazy for him to stand on the platform and speak about this matter. Mao Ming put forward an innovative idea - designing a deformable body, successfully breaking the technical "bottleneck" of engine output limit, and perfectly solving the problem of slow speed of amphibious combat vehicles in the water. Mao Ming has won two first prizes of national scientific and technological progress and one first prize of national defense technological invention, and has made great achievements in the research of weapon industry. One of his "secrets" is that he still has the determination to fight a "blood path" in a very bitter environment. In his decades of research career, Mao Ming repeatedly braved difficulties and dangers and went deep into extremely cold and hot areas to experiment with tanks. Even in the Northeast test site, where the wind is blowing like a knife, the harsh environment of minus 40 degrees Celsius has failed to stop his enthusiasm for scientific research. Under his design, China made the first information tank in the world - 99A tank. When top scientists break through the "dimensional wall", spread knowledge by means of online lectures and chat with the knowledge seeking public, their spirit is also inspiring a new generation of young people. "Internet plus technology innovation knowledge dissemination" chemical reaction At present, China is on the road from a "big country in science and technology" to a "powerful country in science and technology". Although scientific and technological innovation in major fields continues to make breakthroughs, China is still "thirsty for talents" for scientific innovation, especially the innovation of basic theories of natural science. This requires cultivating a large number of young people interested in natural science and stimulating their enthusiasm for scientific research and innovation. In addition, the dissemination of knowledge on the Internet is mixed, true and false. As a result, some pseudosciences often "exploit loopholes" and mislead many members of the public. China's science and Technology Association's "science creation platform" is part of the "academician opening lecture" jointly with the jitter, watermelon video and today's headlines tiktok. This column aims to enhance the dissemination of knowledge and dissemination of authoritative knowledge through the Internet plus technology innovation knowledge dissemination, thus arousing a wonderful "chemical reaction" between scientists and the Internet platform. The guest columns are all academicians of the Chinese Academy of Sciences and the Chinese Academy of engineering. They stand at the forefront of science and technology in the fields of tank innovation, high-speed rail safety, geology and lunar landing engineering, and share top scientific and technological knowledge and rich life experience through online lectures. Many of these academicians are 80 or 90 years old and are authorities in various fields. They share knowledge online in an easy to understand way and interact cordially with netizens. Their spirit of painstaking research and perseverance to climb the peak of science and technology also moved many netizens. "It is unexpected that millions of people watch a program. The short video platform is a new and good stage for the dissemination of scientific knowledge." Academician Liu Jiaqi said. In his opinion, academicians go out from the study, laboratory and classroom and popularize knowledge to the camera and the public. This form of knowledge sharing not only has a strong attraction to science lovers, but also has a great diffusion ability in the dissemination of the innovative spirit of scientific knowledge. Moreover, the strong communication effect combined with the communication and interaction with netizens has also brought academicians and netizens watching lecture videos closer to each other, both intellectually and emotionally. Netizen: This is the "Star" we want to chase In fact, on the short video platform, in addition to the popular science lectures of academicians, scientists' inspirational stories and short videos related to scientific research spirit, many popular funds have been made. Taking tiktok short video platform for example, the reading volume of the related topic of the late hybrid rice Yuan Longping is nearly 9 billion. When Shenzhou thirteen carries the tiktok of the whole nation, the search volume of the relevant video is 1 billion 40 million, and the reading volume of the topic related to female astronaut Wang Yaping is over 500 million. In March 22, 2021, the son of Peng Pai martyr and the first general manager of nuclear submarine Peng Shilu died. The Xinhua tiktok account was broadcast the last video of his nuclear industry to encourage the younger generation of nuclear industry. In just 21 seconds, the content has played more than ten million and won nearly one million praise. Whenever the story of an outstanding scientist is known through a short video, netizens in the comment area will always type "this is the 'star' we want to chase". This simple comment is easy to get a wide response from netizens. This comment alone can get hundreds of thousands of praise. Through short videos, people find that scientists are not unattainable, and they are as keen to express and convey ideas as ordinary people. Only in their eyes, the inheritance of the spirit of scientific innovation and the breakthrough of scientific research achievements are their lifelong pursuit of dedication. Nowadays, pan knowledge short video is rising and becoming a new trend. According to the vice president of Beijing zitiao Network Technology Co., Ltd Editor in chief Zhang Fuping, "the tiktok content of short video content has occupied 20% of the total video volume of the whole platform. 1 of the 5 videos we have seen are universal knowledge videos. Meanwhile, the knowledge broadcast of the pan is over 1 million. The content of the science and technology innovation is becoming one of the favorite contents of the platform users." On the short video platform, people have the opportunity to listen to astronomers from the National Astronomical Observatory talking about the stars and the sea, to listen to senior professors of physics use their childhood anecdotes to interpret physics that makes people confused, and also have the opportunity to understand the seemingly unpopular but interesting knowledge of aesthetics, Atmospheric Physics, geology and other disciplines at any time through live broadcast. Scientists also have an additional channel to share knowledge and show themselves. As a netizen said in the comment area of the program "Academician's lecture": "The knowledge and spirit of scientists and academicians will form the daily growth of ordinary people. Even if it can't change our life trajectory, at least when people look back at these people who are deeply rooted in the field of scientific research and constantly promote the development of the motherland, they will also be moved by the attitude of studying bravely."
