Bringing System to Great Tang

Chapter 664 The New Method of Measurement Is Good Time (Second)

"Ling the watch, one watch for each person, and an abacus to match the land area of ​​the court."

In Lijiazhuangzi, Li Yi handed out things to 220 students.

Long tape measure, short tape measure, abacus, form, pen, one-time-preparation table from one to one hundred.

"Remember the area formula of the circle and the triclinic quadrature technique. Don't use the area of ​​a three-dimensional sphere. Didn't Zu Chongzhi give it three points, fourteen, five, ninety-two six? It's calculated according to three points and fourteen."

Li Yi went on to say that the current formula for calculating the area of ​​a circle is the square of the diameter, multiplied by three, and then divided by four.

If the diameter is eight, the square is sixty-four, multiplied by three is 192, and divided by four is forty-eight.

Calculated according to the circle area formula, the radius is four, the square is sixteen, multiplied by the pi ratio of 3.14, and the number obtained is fifty.24...

When you get to the land, you encounter a triangular land, which is still irregular. First, measure the amount of steps that can be used for a large piece of land, and then estimate a little.

What Li Yi gave is the triclinic quadrature method, which knows the length of the three sides of a triangle to calculate the area of ​​the triangle.

When measuring, you don’t need to take steps, but use a measuring tape to say how many feet a good step is equal to, and both parties convert it.

Two hundred and twenty officials have work, twenty are responsible for the land around Chang'ancheng, and ten in each county.

They are responsible for teaching and statistics, and supervising by the way, with a lot of measuring tapes, pulled by carts.

They are eight hundred decent officials. Whoever dares to cheat can be impeached on a small book.

The officials set off, shouldering the heavy task of surveying the land.

When the Jingzhao Mansion was in chaos, the court ordered that the land should be cleared again. There was news that the rent will be calculated on the basis of the mu in the future.

People who have annexed the land through various means are dumbfounded, how can they? Can't wow!

Calculate the rent on the basis of mu, and my family has to pay a lot of rent every year.

The people who taught Shao Tian and the people who sold Yongyetian were happy, and after recalculating, they could pay less rent.

The Yonghe Tune was cancelled again, and life at home can be considered better.

The people of the big family who were officials in the court sent a letter to tell the family about the situation in Jingzhao Mansion, and they would definitely adopt the same method in the whole Datang in the future.

If you don't want to pay more rent out every year, think of countermeasures quickly.

The court was unexpectedly calm, no one was impeached, and the doctor and a servant were still locked up.

Your Majesty wants to implement a new policy in Jingzhao Mansion, but it is useless to oppose it, and will involve himself in it.

Many wealthy households wailed, feeling that the way they tried was to cut their flesh.

"In this way, there will be no worries about land mergers. People who have no land will not pay any rent and just find a way to make money."

At noon in the heavens and on earth, Yao Chong and several people gathered for dinner again, and Lu Huaishen had a smile on his face.

Zhang said that he used a pen and ruler to calculate there: "Hook three strands, four strings and five, and the two right-angled triangles together form a rectangle.

One side is three, one side is four, and the area is twelve. Divided into two triangles, one is six.

Then calculate according to the formula.

The perimeter is three plus four plus five, twelve, divided by two, six, six minus three, multiplying six minus five, multiplying six minus four, which is six, and then multiplying six, thirty-six.

Thirty-six squares, six six thirty-six, equal six, yes. "

He chose a dumb method to verify the correctness of the formula and found the data pair.

"In this way, it will be convenient to calculate the area of ​​the triangle in the future. The area of ​​the circle, Zu Chongzhi, is three and three to four, which is quite different."

Wei Zhigu is looking at the formula for the area of ​​a circle, which is different from the one-by-one method that has been used now, and is more accurate.

Bi Gou was worried: "The old man is worried that the locals know that Jingzhao Mansion's renting acres will be chaotic, and the big family may have trouble."

"What's the uprising? What's the uprising? Spreading rumors? The speed of their getting news is as fast as the imperial court dispatched to the capitals?"

Song Jing is not afraid, the court has soldiers, and court documents are passed out through the post.

Tell the local yamen to post the Qingzhang field in Jingzhao Mansion and collect rent according to the number of acres.

People who have no land know about it and hope the court will put the decree in the local area as soon as possible.

No matter how powerful a locality is, it cannot instigate the people. With their own manpower, could the soldiers of the imperial court be a display.

He shook his head when he thought of the current surroundings, "Could it be that Li Yi made use of the Turkic civil strife, the difficulty of Khitan's dependence, and the defeat of Tubo that he proposed?"

He suspected that it was too coincidental, why didn't he mention it long ago?

"Next year, my household department will only charge more for renters in Jingzhao Mansion, less money for adjustment, but more money for businessmen."

Bi Gou regained his happiness again, and he hoped that Datang would roll out as soon as possible.

This year, Jingzhao Mansion, next year can clear the land in most places in Datang, by the way, the taxation work will be followed.

Yao Chong looked at the people walking under the sunlight outside the window: "One tax, one stall renting an acre, all targeted at the wealthy and wealthy businessmen."

"The dictionary will come out next month, and the newspaper staff will be trained by the end of the year, targeting other families."

Zhang said look at Lu Huaishen, Lu Huaishen is a member of a large family.

Lu Huaishen looked outside the window together: "The old man is what a family, it's just a side branch."

"If everything goes well, the prosperity of Datang will really come. Chang'an has changed a lot in the past two years."

Yao Chong, who was still looking at the people below, showed expectation in his eyes.

He watched for a while, but didn't see a pedestrian in torn clothes.

It means that everyone has money, at least there is money to buy clothes.

Can buy clothes, of course, no problem with eating.

"Song De." Lu Huaishen saw an acquaintance.

Song De drove the car with many watermelons on it, and walked over under the protection of a group of Yulin Feiqi.

"He went to sell watermelons in the East and West markets?" Bi Goo looked down.

"Li Jiazhuang's watermelon is not enough for himself, how can he sell it? He is sending it to Beitianfang.

Lijiazhuangzi gives things to Beitianfang every day, usually leftovers from Zhangjiacun.

It’s hot recently, and it’s not raining. Just sit and sweat. Let’s eat. "

Zhang said he took a look and ignored it.

Before they finished eating, Song De appeared again. The watermelon in the car disappeared and replaced with a mess.

"His car is loaded with old clothes? And leather jackets, where did I buy them from? Change them with watermelons?" Lu Huaishen was puzzled again.

"I went to the pawned place, dead and unredeemed clothes, what does Li Yi want old clothes for?" Yao Chong raised his brows.

When others go to the pawned place to buy things, he will not pay much attention to it.

Li Yi bought several cars at once, how could he not think about it.

"At night, I will go to Lijiazhuangzi to see ~www.wuxiaspot.com~ Bi Gou looks at Yao Chong triumphantly. Yao Chong can't go now.

"I'll go too." Song Jing decided to have a company with Bi Gou.

"By the way, ask him if there is any big move, don't throw it out suddenly, and don't know who the prime minister is."

The same goes for Zhang Shuo from Lijiazhuangzi to make a request.

Everyone nodded, yes, ask, Li Yi has been honest for a while, now he is not crazy, right.

After eating, everyone went out, without the coolness in the heavens and the earth, and the heat waves rushed across their faces.

"The merchants who stocked ice last year didn't earn less this year. What better way to cool off the heat? Go to Lijiazhuang to ask in the evening."

Bi Gou was so old that he could hardly bear this kind of weather.

Brothers and sisters who read books outside the station, are able to subscribe to the starting point. In addition, they need monthly and recommended tickets to see if they have them. The farmer bowed.
