What is the universe? What is a SpaceLab? How did paleontology exist? What are the physical elements in the music? What kind of colorful world is hidden in the shells of the ocean?
From December 29 to 31, at 7:00 p.m., the Bureau of Science Communication of the Chinese Academy of Sciences and Douyin will jointly hold the "2022 New Year's Eve Science Speech of the Chinese Academy of Sciences", and accompany you to the New Year's Eve in the Douyin live broadcast room of the "Institute of Physics of the Chinese Academy of Sciences". From the origin of mankind to the latest innovations of the Chinese Academy of Sciences, from the "black soil granary" to the quantum revolution, from the univariate quadratic equation to the gauge field theory, Wu Xiangping, academician of the Chinese Academy of Sciences, Wang Yuan, director of the China Paleozoological Museum, Cao Zexian, researcher of the Institute of Physics of the Chinese Academy of Sciences, and other scientists, Yuan Lanfeng, Li Zongjian and other Douyin Kopp masters have explained the doubts of netizens one by one.
Douyin search for "Chinese Academy of Sciences New Year's Eve Speech", or enter the newly launched Douyin Learning Channel, you can find the speech entrance, welcome to watch on time.
In old Chinese, the common meaning of "宇" is space, and the common meaning of "Zeus" is time, which together refers to endless time and space. Chen Ziang wrote "Carrying the universe to hurt far away, ascending to the high platform and writing worry", Li Bai wrote "Looking down at the universe, the four are all waves", from ancient times to the present, human beings have never stopped reverie of heaven and earth and the exploration of the universe.
Fortunately than the ancients, we no longer need to use myths or poetry to imagine what the universe is. With the development of science and technology, we can already see the face of the universe through technological means.
On January 14, 2021, the Beijing-Arizona Sky Survey (BASS) team of the National Astronomical Observatory and the Dark Energy Spectrum Survey (DESI) team jointly released the latest huge two-dimensional cosmic map, which covers 20,000 square meters of the sky, accommodates 10 trillion digital pixels and contains 2 billion celestial bodies. However, what kind of magnificent world is hidden behind the images and data, and how do we ordinary people understand the universe?
In the Douyin live broadcast, Wu Xiangping, an astrophysicist and academician of the Chinese Academy of Sciences, will share his research results for many years.
The old saying that "soldiers and horses do not move grain and grass first" shows the importance of grain to the military and people's livelihood. The development of modern agriculture has made the global granary more abundant than in any previous era, but this does not mean that the problem of global food security has been completely solved. Land resources and freshwater resources are rapidly depleted, and at present, 100 million people in the world are still in a state of severe hunger. So, how do you produce more food with limited resources?
In 2021, the answer given by the Chinese Academy of Sciences is to try to turn carbon dioxide into starch by artificial synthesis. In September, the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences published the results of this research in the journal Science, which will not only have a revolutionary impact on food production, but also greatly promote the development of the biomanufacturing industry.
At 8 p.m. on December 29, Cai Tao, an associate researcher at the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences, will bring you a lecture on this technology. Caring for the future of mankind is not only concerned about the universe, but also about food and vegetables.
Do you know how many years it takes to generate a 1 cm black soil layer? Do you know how much the area of black soil in our country decreased between 1958 and 1990? The answers are 200 to 400 years and 4.08 million hectares, respectively. Black soil is known as the giant panda in the cultivated land, and is a precious treasure given by nature to mankind. Northeast China is one of the four major black soil areas in the world, but unfortunately, the degradation of black soil has always threatened national food security and the ecological environment of Northeast China.
In this case, what has modern technology done and what else can be done? Guan Yixin, a researcher at the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences, will bring his thoughts and answers to the Douyin live broadcast.
Can mammals give birth in space? On the space station, is it possible to achieve a circular supply of food and other materials? After leaving The Earth, how will the human skeleton, nerves, and immune system work?
These brain holes are not the imagination of science fiction movies, but the daily life of space science experiments. With the development of China's manned spaceflight project, the scientific problem of going to space research is no longer a fantasy. Space cold atomic clock experiments, air-ground quantum key distribution and laser communication, gamma-ray burst bias detection, higher plant growth research, space cell culture... What are the mysteries behind these delicate and complex vocabulary? Is it possible for humans to move to outer space in the future?
Zhang Wei, researcher of the Space Application Engineering and Technology Center of the Chinese Academy of Sciences and director of the Application Development Center, will bring you a speech on "Wonderful Space Science Experiments", if you have any questions or ideas, you are welcome to go to the live broadcast room to ask him questions. Perhaps the next major scientific discovery is contained in your whimsical imagination at this moment.
What kind of creature was a dinosaur? Which dinosaurs lived in China and what kind of life did they live? Why is there so much interest in it, and how do paleontologists look for dinosaur fossils?
In the face of these questions from ordinary people, Wang Yuan, director of the China Paleozoological Museum and researcher of the China Institute of Vertebrate Paleontology and Paleoanthropology, decided to do a comprehensive science popularization in the Douyin live broadcast room. At that time, the single crested dragon that has no flesh and no joy, the small robber dragon that flies into the blue sky, the Qingdao dragon with a long skull stick, the Mamenxi dragon with the longest neck, the Gansu horsemane dragon that eats grass, and the Lufeng dragon who is known as the first in China... Will accompany Douyin netizens to spend a mysterious and pleasant half an hour.
What are the relationships between hearing, music and physical energy? What physical knowledge in life is we ignoring?
On Douyin, Associate Professor Chen Zheng, a physics teacher at Beijing Jiaotong University, calls himself a "big player in science experiments." He took Douyin netizens to visit the Institute of High Energy Physics of the Chinese Academy of Sciences, and also demonstrated the wonderful experiments at this year's National Science and Technology Week, he once analyzed "how to take the earth to travel" during the "Wandering Earth" hot screening, and also used short videos to popularize the principles of thermomagnetic engines, rotating magnetic fields and optical dispersion.
On December 30, he will also sit in the douyin live broadcast room and talk about physics from the perspective of hearing.
When you think of the quantum revolution, what comes to mind? Was it Planck, the father of quantum mechanics, or Einstein, who won the Nobel Prize in Physics for proposing a quantum explanation of the photoelectric effect? The first quantum revolution gave birth to modern technologies such as transistors, lasers, nuclear magnetic resonance, and global positioning systems, which enabled mankind to enter the information age and completely changed the course of human history, so what will the second quantum revolution bring, and how can we take the lead in change?
Yuan Lanfeng, deputy director of the Science Communication Research Center of the Chinese Academy of Sciences, is both a scientist and university teacher, as well as a popular science creator with 3.86 million fans on Douyin. He had talked about how to popularize popular science quantum information on Douyin, asked what the end of science was, and now, he decided to extend these questions in the Douyin live broadcast room, and spent twenty minutes detailing what he understood the second quantum revolution. If you care about the fate of human technology for the next hundred years, don't miss it.
What did a 6,500-year-old shellosaur look like? What are the habits of the "Prince Charming" of the vortex family? Is the red brick snail poisonous? What are the secrets of a rotary snail shaped like the sun? Is the cat's eye salamander a cat from the sea? Are the sawtooth oysters from ancient myths from 100 million years ago?
Li Zongjian, a member of the Research and Learning Committee of the Oceanographic Society of China, has a Douyin account like a short video version of the Encyclopedia of Shells, he not only takes netizens to appreciate different types of shells, but also explains the little-known scientific mysteries in the shells: the Nautilus demonstrates the existence of the theory of cosmic expansion, shells of the same thickness are five hundred times harder than artificial marble, the colorful spiral pattern of candy snails is most likely the product of self-protection, and the chicken heart snail with black and white texture contains more than a hundred toxins in the body... On December 30, Li Zongjian will take his shells into the Douyin live broadcast room and get close to the ocean with netizens.
If you pay attention to the account of the Institute of Physics of the Chinese Academy of Sciences, or "elective" through the September 4 "Reading Perception of a Reader" Douyin open class, you will certainly not be unfamiliar with Teacher Cao Zexian.
Speaking of the theory of relativity, he said: "What reason do we have not to learn, people were only sixteen or seventeen years old when they were created." Speaking of "transforming invariance", he used the analogy of "wedding vows": "The heavens can change, the earth can change, I can change, but there is one, you can't change." ”
Witty, humorous, good at simplifying the complex, in-depth and simple, Cao Zexian not only wrote a lot of works in the academic field, but also very popular in the field of popular science. For many years, he has taught physics and philosophy at the University of Science and Technology of China, the University of Chinese Academy of Sciences, Tsinghua University and many other universities. In 2019, a video of his lecture using the principles of physics to interpret the instability of long-distance relationships became popular on Douyin, receiving a total of 65.16 million views and 2.58 million likes.
So this time, how will Teacher Cao tell the proposition of "from unary quadratic equations to gauge field theory"? On December 31, the last day of 2021, he will start this intellectual journey with everyone in Douyin Live.
Learning at TikTok shortens our distance from knowledge.
Understanding physics, understanding the universe, the last three days of 2021, let's trace the origin of civilization together and reach the infinite future together. Here is the full schedule of this lecture:
The wonderful content of the lecture will be updated on the Douyin learning channel in the future, welcome to pay attention.
