At Shenshi (three o'clock in the afternoon), Li Chengzhi walked out of the Yamen without hesitation. But apart from him, no one else was seen walking out of the Yamen.
All the officials and subordinates of the eunuch gathered in the accounting department, and even many officials from Taimiao, Taizhu, Taile and other eunuchs were summoned. Nearly three hundred people gathered around the accounting platform.
There are three people in each group, and the table is filled with calculation chips and paper. On the paper, large and small circles are drawn, as well as polygons with six sides, twelve sides, twenty-four sides, etc.
The former is easy to understand, and the latter is the circle-cutting method used by Liu Hui, Zu Chongzhi and others to find pi. Naturally, it was used at this time to verify what Li Chengzhi gave: three feet, one foot, four inches, one minute, five centimeters and nine millimeters.
Are the values from six seconds to seven seconds (3.1415926-3.1415927) correct?
More than three hundred people gathered together, but not much noise could be heard in the hall. Only Taishi Ling Zhao Sheng, Deputy Ling, and Taiyue Ling Gongsun Chong rushed back and forth to various calculation stations to verify the data calculated by the previous and lower stations. After calculating for nearly three hours, by the time the lamp was turned on, four to five thousand circles had been drawn and the circle had been cut to thirty-six times, but there was still no error in the data given by Li Chengzhi.
Where is this?
Not to mention the seven-digit number of Zu rate (Zu Chongzhi), it is the five-digit number of Hui rate (Liu Hui). It takes ten days to cut a circle with 300 people. And there can't be any mistakes in the middle...
Zhao Sheng and Gongsun Chong naturally understood this truth, but they had to calculate it no matter how slow they were.
If we really want to prove that this set of data is correct, it means that they can develop more sophisticated calendars than the existing calendars, including Zu Chongzhi's "Da Ming Calendar": Zu Chongzhi was the father and son who worked on it, but they combined the power of the imperial court
……
Liu Fang and Cui Guangduan were sitting in the hall, with a wooden board in front of them. They held charcoal pencils (carbonized wooden sticks) in their right hands, and kept checking the numbers on the wooden board according to the numerical symbols on the paper in their left hands.
Written on the paper are symbols such as "+", "-", "x", and "÷", as well as numbers such as "1234567890". It looks like Li Chengzhi's notes.
The numbers are just that. During the Shang and Zhou dynasties, our ancestors had 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 the algorithm of using pens to form vertical strokes given by Li Chengzhi.
Is it twice as easy and faster than calculating?
In the future, sorcerers and sorcerers will no longer have to carry a bag of calculations and run around, they can just use a wooden stick to draw on the ground.
There is no need for a warlock to have an assistant by his side to record at all times, because the warlock can calculate directly on paper and record every step clearly.
There is no need to worry about making random calculations, resulting in one or even several days of hard work falling short...
This not only saves calculations, space, and time, it is not an exaggeration to say that Li Chengzhi has made great achievements in the contemporary era.
As for whether it will benefit the future, we have to wait until Li Chengzhi dies...
After checking the calculations for a while, the two old men stopped writing together, looked at each other, and sighed in unison.
Cui Guang hesitated and said: "We can't really just let him go around for three months. If you have merit, you will be rewarded. Why should you give him a first and a half grade? But it has only been a few days since he was appointed?"<
/p>
Liu Fang muttered: "I don't have to worry about this. It's a meritocracy. If anyone doesn't like it, let him try it. What I'm afraid of is: what if His Majesty sees that he is so proficient in arithmetic, and simply leaves him in the eunuch?
Do it?"
"That's not possible!" Cui Guang shook his head categorically. "How could such a talented person succumb to such a trivial path with such great ambitions today? Don't worry... At most, it's just a slight punishment because he beat King Ruyang."
..."
"What about Gao Zhao?" Liu Fang asked again.
"It must be okay!"
Cui Guang said: "You don't have much contact with Gao Shouwen, so you don't know much about him. If he really annoyed Li Chengzhi, how could he endure it until now? He would have taken action long ago..."
"Then let's go!" Liu Fang said decisively, "If you do good deeds, you will not be rewarded, and you will not be expected to do good deeds. For such great achievements, at least he must be promoted to one level, but not in the eunuch..."
This is because he is afraid that if something goes wrong, Li Chengzhi will be imprisoned in the eunuch by Yuan Ke.
"Then Dr. Guozijian, the seventh grade, is just right..." Cui Guang said with a smile, "The eunuch also has the concurrent job of teaching students arithmetic and the Book of Songs..."
"Haha... really kill three birds with one stone?" Liu Fang also laughed, "I forgot for a moment that the Li family in my ancestral home is the heirloom of "Han Shi", and Li Chengzhi is an unparalleled poetic talent..."
……
If Li Chengzhi knew that the two old men were plotting to treat him like a donkey, he would most likely scold his mother.
After leaving the temple, he went to the West Market and bought some fresh fruits, yogurt, cheese and other things.
After returning home, I saw that the number of people in the house had more than doubled. Taking a closer look, I found Gao Zhan sitting on the attic in the middle courtyard, enjoying the mountain breeze and drinking a small drink.
"Why don't you go to the office during the day if you're not stargazing?" Gao Zhan asked strangely.
He also came at the next shift at three o'clock at Shenshi, but he missed it. After asking, he found out that Li Chengzhi had gone to the Yamen shortly after dawn.
"Ling Cheng has given 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 deflated rubber ball. He suddenly became shorter and said with a bitter look on his face: "Father said it, it will be 25%..."
Li Chengzhi hissed.
He said that there would be no profit if it exceeded 30%, but Gao Zhao really only kept half of it?
Are you really not polite at all?
Forget it, let’s just say two and a half percent. I think those jealous people will feel better after hearing that they have to pay such a heavy tax...
Li Chengzhi sighed: "Bring the ice, call the servants you arranged to sell over, and now teach them how to make and sell..."
Gao Zhan was so happy that he jumped down to the attic.
I finally know how Li Chengzhi sells ice...
……
Two moments later, Gao Zhan hiccuped one after another.
His stomach was almost bulging, but he still held a wooden bowl, scooping out small spoonfuls of smoothie and putting it into his mouth.
As soon as you take it into your mouth, the fruity aroma, milky aroma, sweetness and so on are constantly impacting your taste buds. As the smoothie falls into your stomach, a hint of coolness is secreted into your heart and spleen. Another burp makes your pores open and your whole body is filled with excitement.
Incredible comfort.
Who would have thought that ice can be eaten like this?
When it comes to eating, the palace has the most variety, but at most it’s just chilled wine or some iced honey water.
Not to mention a bowl of money, even two or three coins can definitely be sold...
Li Chengzhi also felt a little emotional.
That is to say, time travel was early, and a hundred years later, in the early Tang Dynasty, ice cream was born. There were all kinds of ice cream, including those with cream fillings...
"Too much is never enough... If you eat too much, your teeth will not hurt and your epigastrium will swell and ache..."
Li Chengzhi persuaded Gao Zhan and then mused: "I'll discuss one more thing with you..."
