In the corner of the palace, Bo Zhengtong, the lord of Bazhou, was talking with a middle-aged man, and the fierceness of the conversation could already be described as an argument. Pen "Fun" Pavilion www.biquge.info

Who is Zheng Tong? The grassroots turbid officials of Liang State, the 'Mai Divine Appearance' on the streets of Jiangling, the national capital, based on 'professionalism', is omniscient in astronomy and geography, regardless of the explicit rules and unspoken rules.

Seeing people and talking about people, talking about ghosts, the kung fu on the tongue is called a sharp, and the ability to observe words and colors, and figure out people's hearts is quite strong, and his acting skills are superb, and he is already the overlord in the 'Mai Divine Appearance'.

However, today Yuwen Wen actually saw Zheng Tong's mood swings, and the opponent's verbal battle had not lost to anyone other than him.

Many people involuntarily make small movements when they are emotional, Yu Wenwen's ears will move involuntarily when he is emotional, and he found that Zheng Tong will clench his fists when he is emotional, and his left hand is repeatedly clenched, relaxed, and clenched again.

This is the case with Zheng Tong's performance today.

Yu Wenwen was quite curious about that man, he felt that it was definitely not easy for someone who could fight with his tongue to make Zheng Tong fall behind, and he himself had the upper hand because with the knowledge of later generations, he could make Zheng Tong irrefutable, but now this person can do this, I am afraid that there is real material.

As the so-called 'beating the dog depends on the master', although Zheng Tong is not Yuwenwen's dog, but he is also his subordinate, the younger brother is in trouble, the old nature has to come out of the mask, not long ago Yuwenwen, who successfully destroyed the alchemist's three views, joined the battle with confidence:

"Zheng Zhubo, I don't know who this is?"

"Assistant Teacher Liu, Qinghe Zhang Zixin has lived alone on the island for more than 30 years, so how did the armillary sphere bring to the island? The operation of the armillary sphere requires hydraulic power, and where does the water power of the island come from, is it the power of the tides? Zheng Tong asked, completely unaware that Yu Wenwen had arrived nearby.

"Zheng Zhubo, this matter is a trivial matter, why bother with it, Liu Mou, may I ask, why should Chenxing not be seen?" The middle-aged man asked rhetorically, not noticing that there was an extra person beside him.

"No, as the so-called mistake is a thousand miles, if Zhang Zixin's armillary sphere is nothing, how can its observations be credible?"

"That's a big fallacy! Zhang Zixin said, 'The day is late after the vernal equinox, and the speed after the autumn equinox', isn't it right? There is also 'the eclipse of the moon in the sun, if it is outside the sun, although it is not a loss', Zheng Zhubo doesn't know? ”

"These two, what Zhang Zixin said is true, but Chenxing's 'seeing' and 'volt' may not be as he said, Zu Wenyuan has been in the clouds..."

A gust of wind blew, rolling up pieces of fallen leaves on the ground, and Yuwen Wen was messy in the wind, not because he was ignored by the two, but because he basically couldn't understand the content of the debate between the two sides.

said that it was basic, because Yu Wenwen at least understood some of these terms, but it was these terms that made him regret not coming here at the beginning, and felt that he should not come here and get involved in the debate for no reason.

Zheng Tong called the other party "Assistant Teacher Liu", then this middle-aged man should be surnamed Liu, as for the assistant teacher, as the name suggests, it is similar to the teaching assistant of later generations, Yu Wenwen already feels bad.

In these years, those who can be called teaching assistants can only be teachers who teach knowledge in Taixue, and they are serious scholars, according to the popular saying of later generations, that is, second only to the great Confucian, no matter how 'talented' Yuwenwen is, it is impossible to argue with the scholar who is second only to the great Confucian.

Teaching assistant, only Taixue is the highest institution of learning in a country, Zhou Taixue set up six doctors, for the next doctor, the rank is four lives; There are six teaching assistants under the doctor, who are sergeants, and they have three lives.

It's nothing just to look at the rank, the key is to be able to be a teaching assistant in Taixue, and the knowledge is real, and the doctor of Taixue is a teaching assistant, and they are all academic tyrants anyway.

There are also other terms "armillary sphere" and "star star", the armillary sphere is a device used to observe the stars in this era, and the star refers to Mercury in gold, wood, water, fire and earth, which means that Zheng Tong and Dr. Liu are arguing about astronomical issues.

Astronomy? I knew that the earth is round, revolves around the sun, and then there are nine planets in the solar system, and what are the zodiac signs, and that's about it!

Seeing that it was a field that he didn't understand at all, Yuwen was timid, and he didn't pay attention to the question just now, so he decided to slip away, but he was just about to turn around, but was discovered by Zheng Tong: "Envoy? It's rude! ”

"Assistant Teacher Liu, this is the Duke of Xiyang County and the envoy of Bazhou Thorn Shi Yuwen."

Yuwen Wen complained bitterly when he heard this, and the middle-aged man also came back to his senses when he saw this, and bowed and saluted: "It turned out to be Yuwen Envoy, Liu Zhuo in the next letter, Zi Shiyuan, just rude." ”

"Envoy, Liu Shiyuan is an assistant teacher of Taixue, and today I came to the embassy to discuss one or two with my humble position."

"Ahh Haha, what are the two discussing, so intense? The officer heard it next door. Yu Wenwen smiled, but he was extremely helpless in his heart.

"Envoy, I am discussing with Zheng Zhubo about what Chenxing should not see." Liu Zhuo replied, "I have heard Zheng Zhubo mention that Yuwen makes Jun quite proficient in astronomy and arithmetic, but I don't know what to say about this?" ”

'Which ear did you hear me say that I was proficient in astronomy?!' Yu Wenwen roared at Zheng Tong in his heart, like countless grass and mud horses galloping past, and Mercury should not see where he understood what was going on.

Yuwen Wen was about to admit it, but then found Zheng Tong gesturing to him, and then his spirits perked.

"I'm ashamed, this official is studying Western astronomy, which is slightly different from Central Plains astronomy... But arithmetic is quite insightful. He had a modest expression on his face, and he didn't blush at all.

"Western? Could it be Persia or Whisk? Liu Zhuo was quite interested when he heard this, "I don't know how the calendars used in these two countries are different from those in the Central Plains?" ”

"Is there a sun-moon parallax? How many years can you calculate the precession difference? He asked endlessly, "In Xia Bucai, the precession difference is about seventy-five years, which is slightly different from Zu Wenyuan's calculation of forty-five years and November. ”

"It is believed that the 24 solar terms should have a 'fixed day'..."

"Do the Western countries measure the shadow of the sun? In the following opinion, the ancient book that 'the shadow of a thousand miles is one inch apart' is really a fallacy..."

Yu Wenwen listened to the other party's questions as if listening to a book from heaven, what "sun and moon parallax", "precession", "fixed day", he didn't understand at all, seeing Liu Zhuo's expectant expression, he only felt bitter.

When a scumbag meets a scholar, no matter how embarrassed he is, he has to be embarrassed!

Yu Wenwen came to Yecheng this time and arranged a task for Zheng Tong, who accompanied him, that is, to recruit talents as much as possible, especially the scholars who are proficient in the subset of scripture and history.

As a result, this Liu Zhuo seems to be very proficient in the calendar, and those who are proficient in the calendar must be proficient in astronomy in these years, and then even the arithmetic level is first-class, and he is also a teaching assistant in Taixue, and the knowledge of the subset of classics and history is not low.

The key is that the name "Liu Zhuo" is somewhat familiar, but Yuwenwen can't remember whether this person has left a name in history.

Zheng Tong gestured, which meant that this talent was 'attracted', and Yu Wenwen needed to work hard, so he had to do it now, and in a moment he had made a decision, and then asked with a smile: "What Assistant Teacher Liu asked, not the director of the official, I don't know if Assistant Teacher Liu has ever heard of stargazing?" ”

"Astrology? With all due respect, stargazing at night is the basis of astronomy, but is it unique in Western astronomy? ”

"However, the so-called stargazing is nothing more than observing the stars with the eyes, while Western astronomy uses astronomical mirrors." Yu Wenwen said, without waiting for the other party to react, and continued to ask: "Does Assistant Teacher Liu know the clairvoyant mirror?" ”

"Recently, I heard that Yuwen envoy Jun dedicated to His Majesty's things, among which is a clairvoyant mirror?"

"What Assistant Professor Liu heard is true, the clairvoyant mirror can make people see the scenery several miles away, which can be described as a military weapon, but compared with the astronomical mirror, it is like the light of fireflies competing with the bright moon."

"It's... Could it be that the astronomical scope can see thousands of miles away? ”

"Haha, Assistant Teacher Liu is good at astronomy, do you know what Saturn looks like?"

"Gold, wood, water, fire, and earth, all star-studded, how can you ever see what it looks like?"

"But with the use of the astronomical mirror, you can know that Saturn has rings, and it surrounds its body like a ring!"

Liu Zhuo was stunned when he heard this, but before he came back to his senses, he heard Yu Wenwen continue: "Jupiter, there are big red spots on it, and the moon is full of ring-shaped craters. ”

"To observe the sun with an astronomical mirror, in order to prevent the sun's scorching eyes, it must be covered with ink-colored glass, so that you can see that the sun is actually round, and there are black spots on it."

"The sky is full of stars, but in the eyes of the astronomical mirror, it is a different appearance, and in addition to the five elements of gold, wood, fire, water and earth, there are several stars circling the sun, but they are not distinguishable by the human eye."

"Envoy, envoy! Where is the Astronomical Mirror? Can you take a closer look? Liu Zhuo asked eagerly, if he hadn't taken into account the etiquette, he would have really grabbed Yu Wenwen's shoulder and shook it.

"This official spent a lot of money to make an astronomical mirror, its body is as thick as a bowl, the length is not less than five feet, the weight is full and it is inconvenient to carry, and it is still on the stargazing platform of Xiyang City, Bazhou Prefecture."

"Bazhou? Bazhou..."Liu Zhuo lowered his head when he heard this, full of tangled expressions, Zheng Tong came up and said: "Assistant Teacher Liu, you have a thousand miles mirror in your hand, although it is not as good as an astronomical mirror, but it is quite interesting to use it to watch the moon." ”

Seeing Liu Zhuo's expression on Ai Ai, Yuwen waved his hand generously: "If Assistant Teacher Liu wants to see it, then look at it casually, but this thing is quite expensive, and it must be limited to being used only in the embassy." ”

"Assistant Teacher Liu won't stay in the embassy tonight, use this clairvoyant mirror to watch the stars at night." Zheng Tong struck while the iron was hot.

"It's... This is bothering..."Liu Zhuo had forgotten to excuse himself, and he was a little embarrassed directly, Yuwen Wen decided to add another fire when he saw this, he encouraged himself in his heart, and then said:

"Is Assistant Teacher Liu proficient in arithmetic?"

"A little research."

"Then you must know the number of Pythagoreans?"

"It's nature."

"This official is familiar with Western arithmetic, and knows that there is a science called geometry, and there is another science called trigonometry, and the study is called trigonometric functions."

"Trigonometry?" Liu Zhuo came to his senses when he heard this, "Could it be that the number is similar to that of Pythagorean?" ”

"However, there is also development, Bazhou Sima Yangji, a stranger to teach Western arithmetic secrets, this secret book records the mysteries of trigonometric functions in trigonometry, and the official has also learned a little..."

"Envoy! Can you tell us a thing or two about this trigonometry? ”

"It's windy here, why don't you talk inside?"

"Please, please make the king..."

"I don't understand what you say, you don't understand what I say, but I don't care what you say, but you definitely care about what I say, so..." Yu Wenwen thought, seeing the fish take the bait, he exchanged glances with Zheng Tong, and then led Liu Zhuo to 'enter the room for a detailed discussion'. (To be continued.) )
