What knowledge did ancient astronomers need?

Taking Zhang Heng, an astronomer in the Eastern Han Dynasty in China, as an example, he was proficient in astronomy, mathematics, mathematics, and literature, as well as meteorology.

However, Zhang Heng is a high-level astronomer, as far as ordinary astronomers are concerned, at least you have to be able to observe the stars, divinate the fortune through the stars, and present it in literary language, of course, we will not talk about its accuracy here, you must know that the ancients believed that the earth was the center of the universe.

At the very least, you must understand the five elements of gossip, astrology, feng shui, arithmetic, water conservancy, ancient astronomers usually served the royal family, and must also understand the political bureau of the time.

Ancient astronomers took Zhuge Liang as an example, that is, to observe astronomy and know geography from above, to gossip and the five elements, to count and to astrology, so the ancient astronomer was a miscellaneous person who knew everything.

Ancient astronomers were supposed to learn the art of divination, which was used to observe celestial phenomena and speculate on national fortunes for the emperor, but the level of observation at that time was very low, and there were no suitable tools to help with observation, so they could only rely on the naked eye.

Astronomy is the study of the structure and development of celestial bodies in space. The content includes the structure, nature and operation of celestial bodies. Astronomy is an ancient science, and it has played an important role since the beginning of human civilization.

The objects of astronomical research are extremely large, extremely long, and extremely physical, making it difficult for ground laboratories to simulate. Therefore, the research method of astronomy relies mainly on observation. Because the earth's atmosphere is opaque to ultraviolet radiation, X-rays and rays, many methods and means of space exploration have emerged one after another, such as balloons, rockets, artificial satellites and spacecraft.

Observe the sky, record celestial phenomena, closely monitor the movement of the sun, and compile a guide to the time of day.

According to the educational materials, the original question: The duties of astronomers in ancient China include (). a.Watching the sky, bRecord celestial phenomena, cClosely monitor the movement of the sun, dCompile a guide to the time of day, and the answers are a, b, c, d.

Astronomers: Astronomy refers to the blind scholars who are famous people who study celestial bodies and the laws of celestial motion, and the representative figures include the ancient Greek astronomers Thales, Aristarchus, and Hipparchus. Representatives of modern times include Galileo, Kepler, etc.

Astronomy is a science in which human beings use the new knowledge of mathematics, physics, chemistry, biology and cutting-edge scientific and technological means to study stars, planets, galaxies and other astronomical phenomena such as black holes in the universe. It is a basic discipline and a comprehensive system that integrates human wisdom. (The six basic disciplines are mathematics, physics, chemistry, biology, astronomy, and earth science).

Astronomy majors mainly learn the basic theories and basic knowledge of astronomy, physics and mathematicsReceived scientific thinking and basic training in astronomical observation, with good scientific literacy, and mastered the basic skills of theoretical analysis, data processing and computer application. The Astronomy major trains senior professionals who have good basic knowledge and basic abilities in mathematics, physics and astronomy, and can engage in scientific research, teaching and technical work in astronomy and related disciplines.

Major courses in Astronomy:

College Mathematics, College Physics, Theoretical Mechanics, Methods of Mathematical Physics, Electrodynamics, General Astronomy, Solid Astrophysics, Foundations of Stellar Physics, Introduction to Computational Astronomy, etc.

Astronomy Expertise and Skills:

1. Master the basic theories and methods of mathematics and physics in a more systematic manner;

2. Master the basic theories and basic knowledge of astronomy, as well as the techniques and basic analysis methods for astronomical observation, and have the ability of theoretical analysis, data processing and computer application;

3. Understand the general principles and knowledge of similar majors;

4. Understand the theoretical frontiers and new development trends of astronomy;

5. Understand the relevant policies and regulations of national science and technology, intellectual property rights, etc.;

Strong mathematical and physical skills are required, and these two aspects should be the most important in astronomy.

Astronomy is a subject with a wide range of coverage, which requires knowledge of mathematics, physics, chemistry, etc.

To study astronomy, you first need to have a certain foundation of physical knowledge.

I think it's important to know physics, mathematics, etc., because that's what astronomy majors offer.

This is a lot more comparative, you have to be able to draw, you have to be good at math, and you have to be good at physics.

Mathematics, physics, chemistry, astronomy, etc. are required to be studied just as basic subjects.

Systematic and professional astronomical knowledge, master certain knowledge of mathematics, physics, geography and so on. I guess it's pretty much the same.

You must have a certain foundation in astronomy, as well as physics and mathematics.

Able to understand the relevant policies and regulations of national science and technology, intellectual property rights, etc.; There are also a lot of them.
