Zhang's family.

The servant hurriedly ran into the study and panted, "Lang Jun, the craftsmen who grind the glasses in the city already have errands in their hands. I heard that the prime minister of the DPRK wants to polish the crystal, and they are willing to work for our family first, but they have to finish grinding the lenses under their eyes before starting work. ”

"What about the craftsman who sharpens the bronze jian?" Zhang Yan asked.

The servant replied, "They are all busy." ”

Zhang Yan said with emotion: "There are so many people in the city grinding lenses, so I can only wait slowly." ”

Fan Jun put down the "Taoist Strategy" in his hand and couldn't help asking: "Do so many people study optics in physics?" ”

Zhang Yan explained: "It's not about studying optics, it's about making an astronomical telescope to see the moon. ”

"Look at the moon?" Fan Jun didn't understand.

Zhang Yan said: "Today's official family said that the sun is in the middle, and the earth and the five stars revolve around the sun. There is also a celestial telescope, which can see the true face of the moon and the five stars. ”

"Is that so?"

Fan Jun's first reaction was not to question, but to become excited.

He has no interest in being an official in the imperial examination, and has liked to study messy things since he was a child.

"In the past two months, officials have been allowed to go to the astronomical institute and use astronomical telescopes to observe," Zhang said. Lined up according to the rank of officials, the hundred officials of the imperial court have almost gone. Then the scholars were allowed to see it, and many scholars had already seen it, and when they returned home, they all wanted to build their own telescopes. ”

"Doesn't the imperial court prohibit this?" Fan Jun asked.

Zhang Yan said: "The official family not only banned it, but also announced the production method of astronomical telescopes. Many officials opposed making it public, believing that it would damage the Son of Heaven and the majesty of the imperial court, but the officials still announced it despite public opinion. ”

Fan Jun exclaimed: "The official family is really the saint of the world!" ”

"You think it's a saint to do this, but many officials are crazy." Zhang Yan smiled bitterly.

Fan Jun asked, "Who made the astronomical telescope?" ”

Zhang Yan said: "Li Xiang (Li Bangyan) started the fastest, invited several craftsmen home, and kept polishing many lenses day and night, and I heard that he had successfully built a telescope. Nowadays, people who want to see the moon either line up at the Astronomical Academy or go to Li Xiang's house. Li Xiang no longer goes to Fanlou, and holds a banquet every night to entertain guests, and after having a good time, he invites the guests to watch the moon together. ”

"Why don't we go too!" Fan Jun said excitedly.

Zhang Yan shook his head: "I am the son of the prime minister, even if I want to watch the moon, I have to go to the Astronomical Institute to line up, how can I go to Li Bangyan's house?" ”

Fan Jun asked, "Is it easy to get in at the Astronomical Academy?" ”

Zhang Yan said: "The Astronomical Institute is too noisy because of the number of suspects, which affects their observation of celestial phenomena, and now only five people are allowed to visit every night. Of course, my father is the prime minister, so I don't have to queue up to go. ”

That night, Fan Jun pulled Zhang Yan and went to the Astronomical Institute to observe the moon, and at the same time asked for heliocentric knowledge.

I went there for several nights in a row, and I got acquainted with the astronomical officials, and I recorded hundreds of pages of content before and after.

It was during this time that Fan Lou took the lead in launching a moon viewing service, placing astronomical telescopes in the corridor of the climbing tower. VIP customers who spend on the top two floors can use the astronomical telescope for free. It's a pity that it was a scrapped lens bought from Li Bangyan, and the observation effect is extremely poor, and I can't see the moon clearly.

Fan Jun studied for half a month, and the day and night were reversed, and his brain was confused.

He slept until noon that day, decided to go out to relax, enjoy the streets of Tokyo along the way, and unconsciously walked near Li Bangyan's mansion.

As a cabinet minister, Li Bangyan usually lives in the official residence on the edge of the imperial city. But his previous mansion was not recovered, and the banquets were held in the old mansion, which meant nothing else, purely because the old mansion was larger.

Fan Jun saw a lot of people queuing, and couldn't help but sneak over, but he came to line up to hand over the name thorn.

There were not only scholars, but also servants sent by officials.

Standing beside a young man dressed as a scholar, Fan Jun said: "It's a Zhejiang scholar below, do you all come to Li Xiang's house to watch the moon?" ”

The scholar said, "Not only to observe the moon, but also to discuss astronomy." With the support of the official family, the imperial court will no longer prohibit it, and astronomy will definitely be a manifestation of science in the future. ”

Fan Jun studied for half a month and wanted to discuss it with others, so he rushed to line up.

After waiting in line for twenty minutes, I finally came to the side door.

A special person was responsible for the registration and asked: "Who is the surname, where is the hometown, and can someone in the family be an official?" ”

Fan Jun replied: "Lanxi Fan Jun, twelve of my father's uncles are officials, seven of my brothers are officials, and I haven't counted the brothers who are officials. ”

The registrant was in awe: "But after the former Changshe County Prince? ”

Fan Jun said: "The county prince of Changshe is the grandfather of the family. ”

"Please come here tonight!" The registrant respectfully handed out an invitation.

Fan Jun left with the invitation, and others were full of envy.

Those who queue up here to hand over their names may not have the opportunity to be invited, and many of them leave their addresses first, and then go home and wait for the news.

Towards the end of the evening, Fan Jun arrived again.

After handing over the invitation, he was taken into the house by a servant.

Most of the guests belonged to the low-level officials in the capital, or the children and grandchildren of the officials' families, and some Jinshi who stayed in Beijing to watch the government.

Ordinary scholars are very few.

Why did Li Bangyan dare to invite the eunuchs at night, but he was not afraid of being impeached and formed a party?

This thing is shooting the emperor's horses!

He knew that he had no other ability but to do crooked ways, and the emperor happened to be promoting astronomy.

After knocking on the side of the palace, he understood the emperor's intentions, so he kept holding banquets and astronomical gatherings.

Of course, due to the large number of guests, it is still necessary to pay attention to the impact.

Li Bangyan did not dare to invite the officials who were qualified to sit in the court, but only dared to receive their children and grandchildren.

The guests sat separately, and Fan Jun was arranged in the middle of the front position.

But he saw Li Bangyan come out in casual clothes, and after sitting down, he said: "Today's official family, pedantic and human, pioneered the theory of heliocentrism, and chased after the three generations of holy kings. Today's banquet is not for anything else, but to invite you to discuss astronomy. In the past, astronomy was a forbidden science, but now astronomy is the study of the Son of Heaven, and you don't have to worry about anything, and you can speak freely if you have any ideas. ”

Li Bangyan pulled the placket and scratched the itch, revealing the tattoo under his neck, and said with a smile: "Wonderful speech, I will have people record it, sort it out and submit it to the official's house." Therefore, what you say may be seen by the officials. ”

As soon as this remark came out, everyone was excited and wanted to perform well.

"Smack!"

Li Bangyan slapped his face, the band began to play, and several actors and actresses entered the venue, but they watched the miscellaneous drama created by Li Bangyan first.

This dog can't change his, as a minister of the Ming Dynasty, he not only insists on script creation, but also is full of a lot of meat jokes.

The acrobatic drama was staged to a happy place, and all kinds of meat jokes made the guests who were drinking laugh.

Fan Jun couldn't cry or laugh, he learned Li Xianggong's vulgar taste for the first time.

Full of wine and food, the actors exited.

Li Bangyan carried the lantern and said, "Gentlemen, come with me to watch the moon." ”

Most of the guests, who had not seen the moon with binoculars, followed Li Bangyan to the courtyard with great interest.

Soon the scene became more lively, and some guests even shouted: "Woohoo, the Guanghan Palace is no more, but where is the fairy Chang'e going?" ”

"Why are there so many pits on the moon?"

"It must have been in ancient times, when there were immortals fighting on the moon, and those big pits were made by spells!"

"The moon is impressive, so can you use an astronomical telescope to see the sun?"

"Haha, someone has seen the sun, and they were almost blinded by the bright light."

“……”

Gradually, there was finally talk about the planets of the solar system.

Fan Jun listened to it for a while, feeling disappointed, because it was all fur, far less than what he had asked for advice in the Astronomical Academy.

Suddenly, someone said: "Poetry has a poetry club, why don't we also form an astronomy club?" ”

"That's a great thing!" Someone responded immediately.

Li Bangyan also heard it, he has been in the cabinet for more than a year, and he has become less and less present in the cabinet.

Even, sometimes it is difficult to deal with official business, and you have to rely on the help of the Chinese scholars.

Many of the officials he used to woo and promote have also changed their courts, and if they continue like this, they will be completely marginalized.

And the emperor's promotion of astronomy was a great opportunity.

He had to follow in the footsteps of the emperor and make the astronomy of Tokyo folk to great effect.

Well, he can't personally participate in this matter, lest he be impeached for forming a party.

He only needs to guide by the side, give some help secretly, and then report the situation to the emperor, so that he can gain the emperor's appreciation.

"Ahem!"

Li Bangyan coughed twice, smiled and said, "You are keen on astronomy and want to form a society, that is excellent. But remember that there should be no slander. I suggested that you usually discuss and study astronomy, and you can write the results into articles. Just like the poetry club makes an anthology of poetry, it also makes an astronomical collection. Make an episode every six months...... Half a year is too long, make an episode every three months, and I will help you present it to Your Majesty. ”

With the support of the ministers, the emperor can also see the article, and everyone present is immediately interested.

"Brother Maoming wants to join the company?" A man next to him asked. This is a friend Fan Jungang knew, this year's top three Jinshi Tang Songnian.

Fan Jun thought for a while, nodded and said, "It's okay." ”

After speaking, Fan Jun went to Li Bangyan's side again, and suggested after reporting to his home: "Li Xiang, there are many people who don't understand astronomy, and they don't understand the heliocentric theory of the official family. The founding collection of the Astronomical Society, it is better to ask the Astronomical Academy to come forward and write some of the most basic articles, so that the members of the club can study and comprehend them carefully. ”

"That's a good idea!" Li Bangyan immediately agreed.

Of course, what he wanted was to curry favor with the emperor, and if the first issue of the Astronomical Society published all the basic theories, it would be tantamount to popularizing the emperor's knowledge to the public.

The Emperor will surely be pleased!

(Alas, it's been a single chapter, and there are still a lot of big brothers who haven't understood it.) ）

(The Chinese Zodiac Sequence was originally divided along the equator, and it was not until the Tang Dynasty that it began to be divided along the ecliptic.) Although the week is divided into twelve equal parts, the day of the week is set at 365.25 degrees. And the zodiac signs from the west are rudely set 360 degrees. It's two systems. ）

(At the end of the Ming Dynasty, the calendar was formulated, and the two were confused for the sake of calculation.) ）

(These two systems represent different astronomical concepts in the East and the West.) To say that the zodiac signs were invented in China not only does not add luster to ancient Chinese astronomy, but rather digs the roots of ancient Chinese astronomy. ）

(The consequences began to appear in the late Ming Dynasty, and now many so-called feng shui and astrology masters rely on the 28 kshatras of the zodiac mixed with the West to deduce the precession.) It's a 360-degree walk on Sunday. This is a departure from the Chinese astronomical feng shui before the end of the Ming Dynasty, when the equator was used for 28 nights, and the path of 365.25 degrees on the Zhou day was followed. ）
