Da Wei Chun

Chapter 308
At Shen Shi (three o'clock in the afternoon), Li Chengzhi calmly left the office.But apart from him, no one was seen walking out of the Yatang.

All the officials and staff members of the Taishi Supervisor gathered in the calculation department, and even a lot of officials from Taimiao, Taizhu, Taile and other supervisors were summoned, and nearly [-] people gathered around the calculation platform.

There are three people in each table for calculation, and the table is full of counting chips and paper. On the paper, large and small circles are drawn, as well as polygons with six sides, twelve sides, and 24 sides.

The former is easy to understand, while the latter is the cutting circle method used by Liu Hui, Zu Chongzhi and others to find pi.It was taken at this time, of course, to verify whether the value given by Li Chengzhi: three feet, one foot, four inches, one minute, five centimeters, nine milliseconds, six to seven seconds (3.1415926-3.1415927) is correct.

More than three hundred people gathered together, but there was not much noise in the hall.Only Taishi ordered Zhao Sheng, Deputy Ling, and Bing Taile to order Gongsun Chong to run back and forth between the counting tables to confirm the data of the calculations on and off the stage.

After counting for nearly three hours, by the time the lamp was held, four to five thousand circles had been drawn, and the circle had been cut 36 times. Still, there was no error in the data given by Li Chengzhi.

Where is this?
Not to mention the seven digits of the Zu rate (Zu Chongzhi), it is the five who verified the Hui rate (Liu Hui), and it is possible to cut the circle with a relay of 300 people.And there can be no mistakes in the middle...

Zhao Sheng and Gongsun Chong naturally understand this truth, but no matter how slow they are, it still counts.

To prove that this set of data is correct, it means that they can research more precise calendars than the existing ones, including Zu Chongzhi's "Da Ming Calendar": Zu Chongzhi was the father and son who studied it, but they gathered the power of the court ...

Liu Fang and Cui Guangduan sat in the hall, with a wooden board in front of each of them. They held charcoal pencils (carbonized wooden sticks) in their right hands, and kept checking and calculating on the wooden board according to the numbers and symbols on the paper in their left hands.

Symbols such as "+", "-", "×", "÷" and numbers such as "1234567890" were written on the paper. It was Li Chengzhi's notes at first glance.

Numbers are nothing more than numbers. During the Shang and Zhou dynasties, the ancestors simplified the numbers to the extreme: one, two, three, four, five, six, seven, eight, ninety.Li Chengzhi just changed the way of writing, which is not very effective.

What really shocked the two old men was Li Chengzhi's algorithm of vertical strokes.

How much easier and faster than counting chips?
In the future, warlocks and art students no longer need to run around with their counting pockets on their backs, they can just scratch the ground with a wooden stick.

There is also no need for a warlock to have to record with an assistant at any time, because the warlock can directly calculate on paper, and every step is clearly recorded.

Don't be afraid of messy calculations, which will lead to a day or even a few days of hard work in vain...

This is more than saving calculations, saving space, and saving time. It is not an exaggeration to say that Li Chengzhi's achievements are contemporary.

As for whether it will benefit Qianqiu, we have to wait until Li Chengzhi is dead...

After checking for a while, the two old men stopped writing together, looked at each other, and then sighed in unison.

Cui Guang hesitated and said: "I can't really just let him play around for three months. If you have meritorious service, you will get paid. Why should you add a first-level and half-rank, but he has only been appointed for a few days?"

Liu Fang pondered and said: "I don't worry about this. If you are only talented, let anyone who refuses to accept it come and try. What I'm afraid of is: If your majesty sees that he is so proficient in calculations, why don't you simply leave him in the Taishijian?" manage?"

"That can't be done!" Cui Guang shook his head resolutely. "How can such a talent be made to submit to such a small way with such great ambitions today? Don't worry... At most, he will be punished for beating King Ruyang that's all. ..."

"What about Gao Zhao?" Liu Fang asked again.

"It must be all right!"

Cui Guang said: "You don't have much contact with Gao Shouwen, so you don't know much. If he really annoyed Li Chengzhi, how could he bear it until now? He would have made a move..."

"Then let's play!" Liu Fang said with a hammer, "If you don't reward a husband for his meritorious deeds, you will lose your expectations for being good. For such a great achievement, at least he must be promoted to a higher level, but he can't be in the eunuch..."

This is because Li Chengzhi was really put in the Taishi Supervisor by Yuan Ke in case something happened.

"Then, Dr. Guozijian, the seventh grade, is just right..." Cui Guang laughed, "He also has the post of Taishijian, and when he has flaws, he can also teach the students arithmetic and the Book of Songs..."

"Haha... Really kill three birds with one stone?" Liu Fang also laughed, "For a while, I forgot that the ancestral Li family is the heir of "Han Poetry", and Li Chengzhi is even more talented in poetry..."

……

If Li Chengzhi knew that the two old men were planning to use him as a donkey, [-]% of them would scold his mother.

After leaving the temple office, he went around the West Market and bought some fresh fruit, yogurt, cheese and the like.

After going back, he really saw that the number of people in the house had more than doubled.Taking a closer look, he found that Gao Zhan was sitting on the attic of the middle courtyard drinking some wine with the mountain breeze blowing.

"Isn't it stargazing, why do you also go to Yamen during the day?" Gao Zhan asked strangely.

He also came at Shenshi (three o'clock) when he was on duty, but he was in vain.After asking, I found out that Li Chengzhi went to the Yamen not long after dawn.

"Lingcheng ordered some other errands..." Li Chengzhi replied vaguely, and then asked, "What did Gao Sikong say?"

Knowing that he was asking about taxes, Gao Zhan was like a discouraged ball, and suddenly he was short, and said with a bitter face: "Father said, it will be [-]%..."

Li Chengzhi let out a "hiss".

He himself said that if it exceeds [-]%, there is no profit, so Gao Zhao really only keeps half of it?

Are you really welcome?
Forget it, [-]% is [-]%. After hearing that such a heavy tax will be paid, those jealous people will feel better...

Li Chengzhi sighed: "Take the ice, call the servants you arranged to sell, and teach them how to make and sell now..."

Gao Zhan was overjoyed and jumped down to the attic.

I finally know how Li Chengzhi sold the ice...

……

Two moments later, Gao Zhan hiccupped one after another.

His stomach was about to bulge, but he was still holding a wooden bowl, scooping up smoothies one by one and delivering them to his mouth.

As soon as you enter the mouth, the fruity aroma, milky aroma, sweetness of maltose, etc. constantly impact the taste buds, and as the smoothie falls into the stomach, the slightest coolness secretes into the heart and spleen.Hiccup again, the pores are stimulated, and the whole body feels indescribably refreshed.

Who would have thought that ice could be eaten like this?
When it comes to food, the palace has the most variety, but at most they only have iced wine.Or drink some ice honey water.

Not to mention a bowl of money, even two or three pennies can definitely be sold...

Li Chengzhi was also a little emotional.

That is to say, it was early in time travel, and 100 years later, that is, in the early Tang Dynasty, ice cream was born.There are all kinds of stuffed cream...

"It's too much...Eating too much will not hurt your teeth, and your abdomen will also hurt..."

Li Chengzhi persuaded Gao Zhan, then murmured: "I will discuss one more matter with you..."
