As soon as Qin Tianjian's astronomy came out, the Confucian doctrine of celestial and human induction collapsed, and a large number of scholars who originally believed in this doctrine changed their ways. The Confucian school of celestial and human induction can almost be called a tree falling down.

Even if some Confucian scholars shouted, 'All things in heaven and earth have their own laws, and the gods have determined them.'

What's more, even if these are indeed the rules formulated by the gods, they also mean that the set of heavenly and human induction and the reincarnation of the five virtues is just a natural law, not the so-called warning of the Son of Heaven who is immoral, and descends from heaven.

It can be said that it is completely the foundation of the set of celestial and human induction. With the promotion of astronomy, less and less people believe in the system of celestial induction.

The prison was open to the public for three months, and for the next three months, officials or scholars came every night to watch the moon or other stars.

Daqian did not restrict the spread of astronomy, but astronomical research requires a very high foundation, mathematics is a must, and there are various star charts, etc., and it is difficult to learn on your own without inheritance.

The appearance of Qin Tianjian made many people interested in astronomical astronomy, and many people directly asked Qin Tianjian to join Qin Tianjian after observing the moon through the astronomical observation mirror.

It's just that Qin Tianjian is not so easy to join, and more than ninety percent of the people are rejected.

If you want to study astronomy, you must be proficient in mathematics, and there are not many people who are proficient in mathematics in this era, and Wang's mathematics will not spread at will, only those who are gifted will teach it.

At the same time, after learning this knowledge, the imperial court will not just use them to observe astronomy, after all, mathematics is very useful, and many places need their help to calculate.

These people will be exposed to the most advanced technology of the Daqian royal family, and once they join, they will not be able to quit for life. Therefore, the selection system is very strict, and not everyone can learn it.

Don't look at the fact that Qin Tianjian is now open to the outside world, this is an edict from Wang Xin, and there was no chance to enter here before, after all, there are also a lot of advanced technologies here that must be kept secret.

If nothing else, such as the astronomical telescope. Astronomical telescopes can be said to be a cross-generational product in this era, and as long as you know the principle, you can quickly make ordinary telescopes.

The value of telescopes in military affairs is known to anyone with a little military knowledge.

In order to prevent the leakage of telescope technology, the imperial court has always kept it a secret. Of course, even if officials and scholars see this astronomical telescope, it is difficult to understand the principle.

In order to make this astronomical telescope, Wang used a large amount of white crystal to carefully grind it. The curvature of the lens is very difficult to grasp, and the light transmittance of the white crystal needs to be carefully selected.

Choosing the right lenses for the focal length can be very difficult, and sometimes even a matter of luck. Of course, scrapped lenses do not mean that they cannot be used, although these lenses cannot be used as astronomical telescopes, they can be used to make ordinary telescopes.

It is said that Qin Tianjian was going to build a giant telescope for observing astronomical stars.

Since the emergence of the doctrine of celestial and human induction, Wang Xin, after consulting with the Wang family, decided to select some simple astronomical knowledge from the Qin Tianjian and compile it into a book on basic astronomy.

The book records the relationship between the sun, the moon, and the earth in detail, explains the causes of solar and lunar eclipses, and records the rotation and rotation of the moon and the rotation of the earth.

The origin of the year is that the earth rotates once, the day is the rotation of the earth, and the origin of the month is the revolution of the moon. There are also some brief introductions to the other stars.

The book "Astronomy" compiled by Qin Tianjian is not complicated, and even gives some astronomical calculation formulas, the most popular of which is the formula for measuring the earth.

At noon, the circumference and diameter of the earth are calculated by measuring the length of the object's shadow and the angle of the sun's rays.

This set of calculations uses the Pythagorean theorem, and the Pythagorean theorem was discovered and proved by Shang Gao during the Bang Zhou period, and there is a detailed record in the "Zhou Ji Sutra", so it is not difficult, and this "Zhou Ji Sutra" is also widely circulated, so many people know how to calculate it after reading it.

After the royal family compiled the book "Astronomy", many officials and scholars rushed to copy it, and began to calculate the various theorems presented in the book.

The most important of these was the radius and circumference of the earth, and some officials and scholars began to use various measuring tools to measure it. The bell tower in Luoyang City has become a must-visit place for many people.

Many businessmen and scholars who came to Luoyang saw that a large number of people gathered at the bell tower every day, and they were chattering. Of course, in order to verify the accuracy, some people deliberately go to other places to make calculations.

After a lot of measurements and calculations, someone quickly came up with the result, and then after many people compared it, they found that the error in the result was very small.

This method of calculation was soon praised by a large number of scholars and officials, and at the same time, it also confirmed the saying that the earth is a ball. Of course, with more and more people's calculations, more and more corroborating evidence is proving this.

In addition to calculating the circumference of the earth, there were even some officials and scholars who wanted to push the boundaries and draw inferences from the past to try to calculate the distance between the earth and the sun with these formulas.

Because there is a lot of calculations in it, it requires the joint efforts of many people, and many officials and scholars have joined it. The imperial court was also very supportive of this behavior, and even provided some calculation tools.

The imperial court saw that astronomy was so popular, so it took the opportunity to add "Astronomy" to the school palace, and it was from this day that "Astronomy" officially became a prominent school, and the imperial court also officially began to assess astronomy.

During the Huai period, in order to measure astronomy, the imperial court built many stargazing platforms in various places. Since the Great Qian pacified the north, began to build an observatory in Mobei, and at the same time the Great Qian also built an observatory in the Western Regions, from north to south, the Great Qian built dozens of observatories, these observatories after calculation, gathered in Luoyang to calculate, revise the calendar.

The development of astronomy also gave rise to many small societies, and with the help of some respected sages and officials, these small groups finally combined to form the Astronomical Society.

Under these circumstances, this book of astronomy was rapidly spread to all parts of the country, and the world view of the round sky was also replaced in this astronomical revolution, which was simply murderous.
