I am the king of the dead

"Wang Yue." Wang Fu said suddenly, "The observatory built by Ulug Beg has a catalog of 92 stars. Did you send it away?"

Wang Yue is sorting out many things in Samarkand and the White Horde Khanate. He also needs to refer to the Ming Law to formulate a new charter, and he also needs to write a letter of credence for the Timur Kingdom. He has a lot of things to do.

He nodded and said, "Send it off."

"Where's the sextant?" Wang Fu continued to ask.

Wang Yue nodded and said, "Everything that can be moved from the Ulugh Beg Observatory has been moved, and those that cannot be moved have drawn pictures for His Majesty's reference."

Only then did Wang Fu nod his head. The wealth of those precious stones and livestock is indeed a harvest, but the observatory is also a huge harvest.

Especially that ten-foot-sized sextant.

The sextant of Ulugh Beg is large, an arc of a sixth of a circle, carved on a huge marble slab.

Each degree is two feet apart, and the curvature is extremely precise. This huge sextant is installed in an inclined tunnel three feet deep and six feet wide from the ground, and part of it protrudes from the ground.

The sextant was named Fakri, who determined the precession to be one degree every 77 years.

Wang Yue has been calculating this number, and finally convinced that Ulugh Beg, the grandson of Timur, is indeed a doctor of astronomy and mathematics.

Uluh Beg was a good man, a good doctor of astronomy, a good doctor of mathematics, but not a good king.

After the death of Ulugh Beg's father, Shah Rugh, the Timurid Empire fell into a long-term situation of fighting against each other.

Wang Fu continued to speak: "Have all the trigonometry, spherical geometry, and geometry diagrams been sent back to Daming?"

Wang Yue continued: "Send it away."

Uluh Beg was a strong scholar. In his geometry diagrams, the values ​​of sine and tangent were accurate to the eighth decimal place.

Uluh Beg devoted great enthusiasm to astronomy and arithmetic, he was neither willing nor clumsy at governing.

In the sect, Ulugh Beg is also a heretic. After Ulugh Beg became king, his son began to incite conservatives to oppose Ulugh Beg's rule.

In the end, Ulugh Beg's son met him in battle, and Ulugh Beg was killed by his son who had high hopes on him by the nameless river.

"Do you think there is really a ball under our feet?" Wang Fu said with a strange expression.

Wang Yue stopped writing, thought for a long time and said: "It should be, Ulugh Beg calculated the inclination of the earth's axis to be 66 degrees."

"This sounds very complicated. Ulugh Beg said that the root cause of the precession is the precession of the earth's axis. The precession is what Ulugh Beg said, and it is called nodal retrograde in our Ming Dynasty."

"So the ground under our feet is not only a ball, but also a slanted ball."

The two Jinshi of Daming struggled to exchange knowledge that they were not very good at.

Wang Yue took out a top, twisted the top to make it spin, and said with a smile: "This is Ulugh Beg's top, and it is called the axis of rotation perpendicular to the ground."

"If I press it like this, his axis of rotation is no longer perpendicular to the ground, and the axis of rotation is in the air, drawing a conical surface. This is what Ulugh Beg said about the precession of the earth's axis."

The spinning top in Wang Yue's hand began to shake, as if a rotating shaft swept through the air, sweeping out a conical surface.

Wang Yue put away the spinning top and said: "There are two days in a year, and the time of day and night are exactly the same. We call those days the vernal equinox and the autumnal equinox. On the ecliptic, there are vernal equinoxes and autumnal equinoxes."

The route the sun travels through the sky in a year is called the ecliptic. When the vernal and autumnal equinoxes occur, the day and night are of equal length. Stargazers mark the vernal and autumnal equinoxes on the ecliptic.

Wang Yue continued: "If it is really a ball, the axis of the earth will not change, so the equinox will not change. But in fact, Liu Xin discovered the equinox in the Western Han Dynasty, and it is slowly drifting from west to east."

"This is what Liu Xin said about regression at the intersection."

"So, assuming it is a ball, there must be a tilt of the earth's axis, which leads to precession."

"And Ulugh Beg calculated that the angle of inclination is 66 degrees, and the precession is one degree every 77 years."

Wang Fu didn't quite understand these things, it was like listening to a scripture from heaven.

But it still seems like a bible.

Wang Fu said with a smile: "All these are sent to Daming, let His Majesty go down and worry about it."

Wang Yue said regretfully: "At the end of Ulugh Beg's notes, he wrote very excitedly: He has a guess and is verifying it."

"But unfortunately, he was killed by his son. He didn't even write down that guess."

Wang Fu also shook his head when he heard that, he could arrange the farming season if he calculated the calendar correctly, but it was a pity that Ulugh Beg had calculated the precession correctly, he had a guess, but he could no longer verify it.

Wang Fu agreed and said, "That's really a pity."

In the entire hall under the high stone arch, there was a rustling sound. Wang Fu did not fully understand the meaning of Wang Yue's expression, but he knew those things, which were of great help to the compilation of the Datong Calendar.

Wang Fu suddenly stopped writing, and said very calmly: "If one day I betray Daming, you will kill me immediately."

Wang Yue also put down his pen, rubbed his wrists, shook his head and said, "Do you know how? With this little power in the Western Regions, is it more powerful than the power to become a teacher in the capital?"

Wang Fu was taken aback for a moment, and then laughed. It was indeed so. He was just a king of a khanate after being overthrown in the Western Regions. When he became a master in the capital, he was the commanding height of power.

"That makes sense." Wang Fu nodded.

Wang Yue took out a manuscript and said, "I have written the letter of credence to King Timur Buzain, please read it."

Wang Fugao first said that his intention to make good friends with the Kingdom of Timur was obvious, and Wala's foothold was not stable now.

"Aren't you going to translate it? Do you just write it in Chinese? Why don't you find someone to write it in Mongolian and send it over? We are Wala, not Ming..." Wang Fu looked at the Chinese national certificate, the format was correct, The writing is very standardized, but the smell is too strong.

Bu Sayin knew it was Wala, but if he didn't know it, he thought it was the letter of credence written by Daming.

Wang Yue spread his hands and said: "This Oara man uses Uyghur-style Mongolian script. Tuotuobuhua is very good at that kind of document. Maybe we also use Chinese characters since Dashi himself can't understand Uyghur-style Mongolian script." .”

"Anyway, the Timurid Kingdom wants to give us tribute to the Ming Dynasty. There are people on their side who can understand Chinese, so let's use Chinese. Save the translation, translate it, and confuse it."

That's why I didn't even know Genghis Khan's code, because I couldn't understand it first.

The code of Genghis Khan was written in Uyghur-style spelling. Later, Kublai Khan introduced the new Mongolian characters. It's strange to understand first.

In particular, the Uyghur script is a pinyin script, each pinyin has no meaning and only pronunciation, what do you think first?

Why did Boyan Timur say that Wala is worse now than when he was dressed in Nandu?

They don't even have a formula for writing, isn't it just miserable?

"Guard Qixue, you give this letter of credence to Dashi." Wang Fu finally decided to ask what to do first, and he told the guards to go.

Not long after, the guard ran back and said, "Dashi said, Mr. Wang can figure it out. If there is a fight, Dashi said he would beat Buzain."

As far as Yexian is concerned, he has long been accustomed to using Chinese. If you ask him to write a crooked Uighur-style Mongolian letter, he can't write it. Isn't that embarrassing him?

Since everyone uses Chinese, and the Timurid Kingdom also pays tribute to the Ming Dynasty, if someone understands Chinese, they can just write in Chinese.

Wang Fu held the letter of state, looked at it for a long time, looked at the seal, then looked at Wang Yue and said, "What's the matter?!"

This letter of credence itself was written in Chinese, so it had a strange smell, and it was also printed first, but the next seal was "Jingshun King's Seal".

These four characters are Chinese characters, and they were the princes bestowed by King Jili to the Wala people when they first went to the capital to pay tribute.

Wang Yue said with a look of disgust: "He knows that the Timur Kingdom is not afraid of only talking about Oara, but if he takes out the seal of King Shun, will Buzain think that Ming is going west?"

"Da Mingqiang, when the Timur Kingdom finds out what's going on, we will also gain a firm foothold in Samarkand."

"This is pretending to be a tiger!"

"This old man is very smart."

Wang Fu put the letter of credence away, and said very angrily: "Hmph, Your Majesty is indeed right, they are all a bunch of unfamiliar white-eyed wolves!"

"When it is needed, when Da Ming is the suzerain, he is obedient, and when it is not needed, he has no respect for it."

Wang Yue looked around and said mysteriously: "I have a good book here, do you want to see it?"

Seeing Wang Yue's mysterious words, Wang Fu asked curiously, "What?"

Wang Yue took out a book from his sleeve, stuffed it to Wang Fu, and said with certainty: "Look, I guarantee your satisfaction."

Wang Fu opened it and saw that it was the Dibao. He was quite pleasantly surprised and said, "Where did it come from?"

"Saiyin Buhua sent it here." Wang Yue said: "Saiyin Buhua also got it from Hetao. It's just this one. After you finish reading it, I'll read it."

"I know, I know, I will copy a copy and return the original to you." Wang Fu said without taking his eyes off it.

It is only when people are in a different place that they know the benefits of Wang Hua. This residence newspaper has the taste of a family letter.

"Have we sent the memorial to His Majesty?" Wang Fu stroked the cover of the book with trembling hands, thinking of something important.

The secret report that Wang Fu and the others sent to the capital was written in milk, and only when it was roasted with fire would the words appear.

This is a delicate job, and it is written in Yinshu, and it has to be translated into Yangshu. It is absolutely possible to keep it secret. It is not afraid of interception, but it is afraid that it will not be delivered.

After all, Samarkand is too far away.

However, this report can be sent to Samarkand, at least it shows that there is a high probability that the memorial can be sent to Ming Dynasty.

Wang Yue said tirelessly: "Send it away."

The reason why Wang Fu kept nagging was not that Wang Fu didn't trust Wang Yue, but that he had to ask.

The memorials of Wang Yue and others traveled from Samarkand to Suiye City, followed the Tianshan Ancient Road to Jiayuguan, and then to Hetao Official Road Post Road, sent to Xuanfu, and finally sent to the capital of Ming Dynasty.

His memorials and Zhu Zhan's memorials on the headlines of Bo's blog are almost the same as the capital.

What Zhu Qiyu read first was Wang Fu's memorial, which was sent tens of thousands of miles away.

"Steal, steal hard! They are all thieves!" Zhu Qiyu finished reading the booklet first, and a familiar sense of sight came back.

Another thief, staring at Daming for stealing.

Chapter 431 Standard time based on Tai'an Palace

Like to steal, this is not exclusive to the Nanya Dynasty or Wala.

There are a sea of ​​people who like to steal all kinds of things from Daming.

In the Western Han Dynasty, Luo Xiahong built a round instrument, and Jia Kui of the Eastern Han Dynasty added a zodiac ring to the round instrument, which was renamed the Zodiac Tongyi.

In the Eastern Jin Dynasty, Kong Ting manufactured a double copper armillary sphere consisting of a Liuhe sphere and a Siyou sphere, and then gradually added a three-star sphere.

The armillary sphere built by Li Chunfeng in the Tang Dynasty has three layers: the Liuhe instrument, the Sanchen instrument and the Siyou instrument.

Shen Kuo of the Northern Song Dynasty simplified this by removing the white ring from the Sanchenyi and changing it to the Armillary Sphere.

In the Yuan Dynasty, Guo Shoujing, an old immortal, liked to go to the ocean and the desert to watch stars, so he simplified the armillary sphere into Jianyi again.

This simplification is not to simplify the function, but to simplify its shape, which is convenient to carry around. It is divided into the equatorial theodolite and the vertical theodolite (that is, the horizon theodolite).

In February of the second year of Zhengtong, Beijing Qintian Supervisor Zhenghuangfu Zhonghe and others gave a performance. The observatory in Nanjing is equipped with instruments such as armillary spheres, armillary spheres, simple spheres, and gubiao. Appearance.

Huangfu Zhonghe asked to send one of the inspectors to Nanjing to supervise the craftsmen to first make it with wood, then transport it to Beijing and then cast it with copper. He copied all of Guo Shoujing's more than 20 astronomical instruments to the Beijing Observatory.

The Beijing Observatory is located in Mingshifang, opposite the Beiya Gongyuan, and is also the Yamen of Qin Tianjian.

Zhengtong was officially completed in four years, covering an area of ​​more than [-] mu.

This armillary sphere was copied to North Korea by North Korean envoys using the same imitation method.

It is to make a one-to-one model with wood, and return to North Korea to cast it with copper.

Later, the history of the armillary sphere was stolen by South Korea.

South Korea printed the armillary sphere on the [-]-dollar banknote, and said that the armillary sphere was invented by them.

After a lapse of nearly 600 years, Daming has not escaped the stealing of South Korea.

To steal is to steal hard.

Zhu Qiyu looked at the drawings sent in his hand for a long time.

"Send it to Wu Jing, let him see if it's useful." Zhu Qiyu took Ulugh Beg's astronomical table and drawings of sextants. There are many mathematical expositions in these documents, and let Wu Jing take a look first.

Xing'an took the order and handed over the document to Xiao Huangmen.

The good man Ulugh Beg was actually killed by his son only two years after he became King Timur.

Now Pusain is Ulugh Beg's nephew, and Ulugh Beg handed over all his military power to his son, and he never stopped studying astronomy.

In the 14th year of orthodoxy, Ulugh Beg advanced 400 years, accurately measured the tilt angle of the earth's axis, and calculated the precession from this.

Why was Guo Shoujing called a god in Yuan Dynasty?Because the Shoushi calendar he made is actually the Datong calendar of Ming Dynasty.

The Shishi calendar has been used for more than 300 years, and it was not revised by Xu Guangqi and others until the reign of Chongzhen.

In the 13th year of orthodoxy, the solar eclipse was postponed by a full day, and the time service calendar was no longer accurate.

The purpose of building Ulugh Beg’s sextant ten feet high is not to exhaust the resources of the people, but for precision. Even though Zhu Qiyu is thousands of miles away, he can feel Ulugh Beg’s love for astronomy and mathematics.

Once the Qin Tianjian can confirm that the movement of the equinox in 77 years is a more accurate precession, then it can be proved that the tilt angle of the earth's axis in Ulugh Beg is correct at 66 degrees.

Then the earth is a ball, and it is a tilted ball, so it can be proved.
