Chapter 56 Six - The Genius Star Warlock
As an astromancer, a third-level astromancer, Wang Linghe personally does the work of the messenger, entirely out of appreciation for Cheng Jinzhou, which definitely does not contain a responsible attitude towards society, the world, and human beings—an astromancer is a genius. I'm too lazy to meddle in the court's business, even if someone dies.

Although it was something he didn't care about, the message in a few words made Mrs. Cheng break out into a sweat.The foundation of the family is in Shaonan, if the imperial court blames it, the Cheng family will suffer the most.

There was no need for Wang Linghe to elaborate, Old Madam Cheng had already made a decision in her heart to send Mr. Star Warlock away, so she dressed neatly, held a walking stick, and called the butler over.

The butler has served for 50 years. He is older than those second-generation sons. He also has white hair and is neatly dressed. At first glance, he looks like a retired old-fashioned knight.To be honest, the status of the Cheng family's chief steward is higher than that of the knight master.

His straight back was in stark contrast to the hunched second butler. Even though the snow in the yard was very slippery, he was still walking in a standard square step in a standard long gown, with little change from usual. .

The old lady Cheng had a dignified expression and said in a dignified tone: "Go to Cheng Feng and get two people, and tell the people below, whether it is what happened yesterday or today, whether it is firewood, rice, oil, salt, or wedding celebrations, don't talk about it, don't ask about it. Don't talk, anyone who dares to chew a word will be immediately killed."

The tone and semantics are like the sunset after the rain, deeply pressing down on the horizon.

The maid next to her shuddered and almost dropped the towel in her hand to the ground, her face paled in fright.

"Ah—yes." The head steward usually had a dignified manner, but at this moment he couldn't hide his surprise, and even hesitated a little.Execution of servants by noble families has always been a gray area, and few people except the royal family speak out openly.Generally speaking, the dead are usually the servants who can't bear it, not the master who is determined to kill.

The old lady who was stationed in the military town with Cheng Wenzheng in the early years was deeply impressed by the three flavors. Without any hesitation or pause, she continued to sternly say to the Cheng family around: "The order just now is also effective for you. No matter where it is One by one, be careful who dares to speak nonsense."

Those who gathered were all the sons of the four branches of Yuanlong in Qingyue. As long as they were restricted, the sons of the sons had no right to speak at all.

Liu Qingshuang lived very close, and was also called here, looked at her toes thoughtfully, and thought: In this way, it will not be easy for the imperial court to know what happened in Shaonan City.

Everyone was obedient, but the old lady continued to speak: "Cheng Feng, take some people to the city wall and bring Jinzhou back."

Cheng Feng was the head of the guard, he answered "yes" loudly, and ran out in the wind and snow, like a standard soldier.

The snow falls intermittently, sometimes it is snowflakes, sometimes it is snow particles, in groups, like cotton candy that has been placed for a long time.

The snow that fell on the ground was loosely piled together, occupying the streets, occupying the gardens, occupying the roofs.Some young people tried to fight it, but finally gave up and let it stand in front of the door like a wall.

At this time, the only thing to be grateful for is the windows, and their importance has been expressed to the greatest extent, surpassing the doors that cannot be pushed open, and the peepholes that lack color.

A long night.

In order to allow the homeless people to survive the first 12 hours, so that they would not die or take risks, the porridge sheds in the four cities have never stopped, and the rich and nobles also try to gather bedding cotton.By the noon of the next day, thousands of shi of grain had been turned into energy to keep out the cold, most of which came from the trading platform.

It is no exaggeration to say that Cheng Jinzhou used his own credit to try his best to keep his father's official title.Otherwise, let alone a riot, even if there are too many dead people, a bad review during the civil servant examination is tantamount to ending his career.

Of course, this pay is worth it.Just the girders and other materials of the collapsed house can make him pay back a lot, and the rest is far from a problem.

There is a huge difference between being born in a wealthy family and being born in a poor family, without money and without money.

The calm victims started a new life, and the officials of the state government office silently took over the work of the government, working like real managers, but everyone had different thoughts in their heads.Few people know exactly what happened, which is the main reason why the magistrate still hasn't received any official reprimand.

Returning to calm is the long-lost Father Sun, who has just ended the chaotic relationship with several other planets, making him look a little weak, and the idle sunlight has no effect on the thick snow.

While the nobles were busy in fiefdom, Liu Kuang came to him quietly.

The status of astrologers is extremely high, far beyond that of local nobles, let alone Cheng Jinzhou.

The latter felt strange, but he hid it well when the servants served tea and water.

Liu Kuang was always paying attention to Cheng Jinzhou's expression, but Xiang Xin, an apprentice astrologist, spoke first. She almost sat down and said, "Mr. Cheng, I still have two questions for you."

"Oh?" Cheng Jinzhou looked at Liu Kuang strangely.When he was studying for a Ph.D., if a doctoral student asked another supervisor a question of the same major in front of his supervisor, it would be tantamount to slapping him in the face. sleep.

Liu Kuang smiled kindly, took two sips of tea, and then waved his hands and said, "I have mainly studied coordinates these years. Although the Euclidean geometry you have learned is similar to the previous generation, it is also different. , I want you to explain it, if you don’t mind, let the old man listen to it too.”

It was the first time he called himself an old man in front of Cheng Jinzhou.This word is actually a kind of intimacy among the nobles of the Great Xia Dynasty. Not every old man is qualified to call himself an old man, and not every old man with status will call himself an old man in front of his juniors. It is more used in Students lagging behind.

If it was an ordinary local nobleman's son, he might be grateful at this moment.

However, Cheng Jinzhou only pretended with a forced smile, and kept saying, "Don't dare to do it, don't dare to do it."

Xiang Xin wrinkled his nose, took out a thick stack of drafts from his arms, spread them on the table, and said seriously: "It's about drawing pictures. I heard that Mr. Wu said that you once said that 17 polygons cannot be used. Ruler made?"

"Have you learned all this?" Cheng Jinzhou was quite surprised.Drawing a 17-gon itself is meaningless, but it is more difficult than inventing a paper-cut method.But if you know the basis of Euclidean geometry, you will find that it is very important - as the most basic geometry, it is more advanced than Pythagoras' mathematics because of the axiomatic structure. If you admit its problem If the assumption is correct and the derivation process is correct, then the answer must be correct.

This kind of thinking has continued to influence the world for more than 2000 years.

Because of this, the geometry based on Euclidean has high requirements on the premise or problem setting. For early mathematicians, their propositions were either directly derived from the five axioms of "Elements of Geometry", or the problems were based on realistic geometry.

The so-called realistic geometric figure is the geometric figure that can be constructed with a ruler and compass—the universality of ruler and compass construction is the main reason why mathematicians recognize it.

Therefore, if people can use ruler and compass to make 17 polygons, then they have one more condition on all related problems. If not, many problems will wait for the invention of other mathematical means.

Of course, just like all famous mathematical problems, the lingering process of studying regular heptagons will always bring mathematicians countless new discoveries, whose value may even be higher than the problem itself.

In Cheng Jinzhou's view, when Xiang Xin thought of the problem of 17 polygons, it means that she has reached the world's first-class level.Especially through the rigor of Euclidean geometry, she took a complete shortcut.

Cheng Jinzhou thought deeply for a while, and when he looked at Xiang Xin, he suddenly felt that he was a master who was going to die in a novel, and the bald-headed little girl in front of him was the protagonist, who was waiting for him to use Dafa to teach him...

"Mr. Cheng?" Xiang Xin called out in a low voice.

"Oh, haha." Cheng Jinzhou seemed to come back to his senses, and said with an embarrassed smile: "I just said that none of the people present could draw a 17-gon."

In fact, he also said that no one else could draw it, and now it should be blown away by the wind.

Liu Kuang pondered and said: "I have been thinking for several days, but I still have no idea. I asked a few friends, and asked them to help inquire at the Astromancer Association, but there was no result. Could you draw it?"

Hearing him talk about such a troublesome process, Cheng Jinzhou has a huge headache, and he can't tell the truth.He shook his head quickly and said, "I can't draw it either."

The main steps of drawing a 17-sided ruler and compass only need 10 steps, follow the process, and any third-grade child who can use a ruler and compass can complete it.But why such 10 steps are the real value. Gauss used a book to explain the situation, so how could he keep them all in his mind.

Xiang Xin said with a disappointed expression, "Then do you think it is possible to draw a 17-gon?"

This is actually the standard problem of the regular 17-gon. If you can draw it, it means that the regular [-]-gon ruler and compass exists. If you can’t draw it, it doesn’t exist. How to draw it is not the main point of attention.

Cheng Jinzhou pondered for a moment, resisting the desire to peek at Liu Kuang, and carefully said: "It should be possible to draw."

"This is a big problem." Liu Kuang narrowed his eyes immediately, put the teacup on the corner of the table and said, "Can you write an article on this and report it to the Association as a result? Many people will definitely care about it. "

A lot of people's concern means a lot of association contribution points, the most important trading unit for star warlocks.

Cheng Jinzhou's eyelids twitched, his heart fluttered, but he said: "I'm afraid this will take a long time to study. I just read books by myself and haven't studied systematically yet."

What he said was soft and honest.The drawing method of the regular 17-gon is something that appeared later than analytic geometry, and it will not be revealed if he is killed, and he really can't write the process.Except for gentlemen who study the history of mathematics, and professionals with profound attainments in related fields, who in the 21st century will have nothing to do with studying such ancient things, and then change to a standard mathematics professor, and the result will still be the same.

"Star warlocks are all geniuses, and geniuses should have their own path." Liu Kuang said with a trace of regret: "You have to hurry up. If you have any questions, you can come to me. You have a chance to become a one-star warlock."

Cheng Jinzhou expressed his gratitude immediately.A one-star warlock can be said to be a symbol of status. The degree of difficulty and rarity can be compared to academicians in the previous life, but the status is still much higher.As for the two-star and three-star warlocks, it shows that there are high and low academicians.

Liu Kuang may not be a pure mathematician, nor is he the top figure in the ivory tower imagined by Cheng Jinzhou, but compared with those full-fledged political animals, he has become pure and kind again.

People are always like this, changing.
