What aspects does the astronomical algorithm include?

Astronomical algorithm includes two genera: pushing steps and calculating books, and the number of skills is divided into seven genera: mathematics, occupation, house-to-house grave-hunting, divination, life script, yin-yang five elements and miscellaneous skills.

The earliest ancient book with astronomical algorithm in China is Sikuquanshu. Astronomical algorithm is a subject that studies the structure and development of celestial bodies and the universe in space. The contents include the structure, properties and operating rules of celestial bodies. Astronomy is an ancient science and has played an important role since the history of human civilization.

By observing the radiation emitted by celestial bodies to the earth, we can find and measure their positions, explore their motion laws, and study their physical properties, chemical composition, internal structure, energy sources and their evolution laws.

Astronomical instruments:

Taoist priests who watched the stars at night in ancient China had homemade instruments similar to astrologers, which could measure the weather and understand the simple operation of celestial bodies.

The first planetarium was a mechanical miniature of the solar system, which was completed by hand according to the clock manufacturing technology. It was not until the emergence of mechanical optical projection astrologer that the word astrologer became familiar to people.

Astrologer is a combination of high-quality optical and mechanical projection system and precise digital control technology, specially designed for large spherical screens and multimedia cinemas. Because the brightness of all the projections is very high, it can be used even if the reflectivity of the projection surface is very low, and the traditional white projection spherical screen is not needed. Gray ball screen will greatly improve the clarity and color saturation of slide and video projection.
