Focus | "Astronomical Male God" tells you how astronomy changes the world

The bright starry sky has been the goal of human beings diligently since ancient times. It is the continuous exploration of the starry sky and the world that human civilization will continue to develop. For the relationship between astronomy and the world, Li Geng, an associate researcher at the National Observatory of the Chinese Academy of Sciences and associate professor of the Academy of Astronomical and Space Sciences of the Chinese Academy of Sciences, put forward his own views: "Throughout the historical period of human civilization, we can find that human understanding of the universe, The ceiling of the knowledge during this period. "

The influence of astronomy on the human world is directly reflected at the level of reality and spirit.

The real level is obvious. Sichuan astronomers in the Western Han Dynasty have created "Taichu Calendar", which has been used for more than 2000 years. The agricultural time has been in an orderly manner, and China has developed a splendid farming civilization. The ancients once thought that the earth was "Tianyuan", and ancient Greek mathematician Pydagoras proposed "the theory of the earth circle". In the end, the doctrine was confirmed because the Magellan fleet completed the first global navigation in human history and opened it. The "Great Navigation Age" has changed the pattern of human civilization. In modern times, astronomy is also the field of convergence of cutting -edge science and technology, including aerospace, physics, chemistry, mathematics, materials, dynamics, information and communication, etc., and is the most cutting -edge representative of human beings.

Compared to the real level of astronomy changes in the world, the spiritual level is relatively easy to ignore, but if you carefully sort out, it can be found that it has been changing human life. In the past years, looking up at the starry sky is what the ancients like to do. They let go of their minds, explore the mystery of the world, the philosophy of life, and create countless shocking literary works, such as Cao Cao's "Sun and Moon, if it is among them; the star and Han is brilliant, if it is out of it," Li Bai's "Dangerous Building Gao Baigai Glores, hands can pick stars, "Yang Shen's" Who knocked the space to shatter the space, and the star fell into the world "... These popular stars' poems painted an important chapter in the cultural territory of the Chinese nation. Today's "star chasing" fever also reflects the spiritual search of the spiritual level after people's material life is satisfied. Li Geng's "History of Astronomy" has become a course sought after by college students. Some students tease him as "astronomical male god". For the relationship between astronomy and the world, the "astronomical male god" made a very brilliant summary: "Astronomy and history are like a brush in the long river of the universe. With these lines, you can see the past, see the present, and even see the future. "

In the face of increasingly diversified reality, some young people are sometimes discouraged, produce negative emotions, and even generate ideological tendencies such as "lying flat". In this regard, Li Geng said that in the long river of the universe, the anxiety in life is just one of them. "The entire earth is just a 'blue dot' in the universe. Look at the vast universe, you can let go. "
