After taking a deep breath, Xu Hui asked: "Thirty miles from Changshui Township, I and Jun are out of each township, Jun is from the east, I am from the south, I don't know the number of steps when I go out, all evil turn to the northeast, Jun and I will, if you order Jun to line five, I to line three, Jun line geometry?" What do I do? ”

This is one of the most advanced calculations of our time.

It's not just about math, it's about geometry!

It's hard to know, and it's not something that everyone can't count.

Zhang Yue listened, the abacus in his hand flicked two or three times, and then raised his head and replied: "I go south two thousand four hundred and four hundred and sixty-two steps, and the northeast turns to the city and one and a half steps with you, and the king travels two thousand nine hundred and thirty-two steps and a half ......."

This topic is too unchallenging for Zhang Yue.

You just need to know that the Han room is three hundred steps in one mile.

This question is a question of sending points.

If you change to a junior high school student, you can probably make it.

Xu Hui's face changed suddenly after hearing this, this is a rather difficult arithmetic problem in his father's "Xu Shang Arithmetic".

He used this to run rampant in the Northland.

Even if someone could figure it out, it would take at least a few days!

However, the young man in front of him has solved the problem in just a moment!

How is this possible?

Xu Hui gritted his teeth, bit his tongue, and said fiercely: "There is a mountain in the west of the tree, I don't know its height, the mountain goes to the tree for fifty-three miles, the tree is nine feet and five feet high, the person stands on the tree three miles to the east, the tree is level with the mountain peak, the human eye is seven feet high, and the mountain is geometric?" ”

Another geometry problem!

In the Han Dynasty, geometric mathematics was the pinnacle of the crown of mathematics.

All mathematicians take geometric calculation as their tireless research direction.

Geometric mathematics is also widely used in land statistics, field acre calculation, fortress construction and channel construction, water conservancy engineering and many other aspects.

Since the Wenhou of Beiping, all the people in the world have taken the study of geometry as the key.

And Xu Hui's topic is indeed jerky.

The surrounding nobles all fell into deep thought when they heard the words.

If they can still find a solution to the problem, then they don't even know how to start this problem.

Xu Hui was even more proud.

This question was one of the obstacles his father encountered when studying the arithmetic of the nine chapters.

After three years of hard thinking, there is something to gain.

And he didn't believe it!

This humble scholar in Changshui Township, Nanling County, can still be counted!!

"The mountain is one hundred and sixty-four zhang nine feet six inches, more than half an inch ......" Zhang Yue turned the abacus horizontally, looked at Xu Hui and said: "I have already said it, don't waste my time!" Let's go together! ”

"Even if we beat up Jun and a few others......"

"You!" Xu Huiqi's hair is about to stand on end!

But he still can't have a seizure.

Xu Hui now finally understands why Mencius debated with Mr. Xu Xing in the Qi State back then, and finally blurted out with great dignity: "The people who rap the southern barbarians also describe the way of the ancestors?" ”

There's no way, I can't argue, I can only curse!

Others were even more furious.

You're bullish, aren't you?

But there's no need to be so humiliating, right?

How will everyone mix in the future?

But they completely forgot that not long ago, they were still thinking about using Zhang Yue as a stepping stone.

…………………………………………

The onlookers were already stunned at the moment.

"This life, if you have the power of ghosts and gods?" Some of the princes bit their tongues, unable to believe what their eyes and ears had seen.

With a weak crown year, and the enemy of several talents in the world?

The last time such a figure appeared in the Han family was traced back to more than 60 years ago, when Jia Yi and Jia Changsha were born out of thin air and dominated the world.

At the age of eighteen, he singled out the scholars of the entire Henan County, and at the age of twenty-four, he made the world bow down.

"Is it another Jia Changsha?" Someone muttered to himself.

Jia Yi Jia Changsha, although he died young.

But he left an immortal mark on the Han family's literary circle and Shilin.

The effects of this are still being felt today.

Who has not borrowed Jia Changsha's stylistic and narrative methods from the articles and strategies of scholars in the world?

And this is even more exaggerated!

He is in the field of mathematics, and he is stronger than the world's talents!

And it seems that I haven't used all my strength yet!

This is an exaggeration!

Jia Yi Jia Changsha is just well-written and knowledgeable.

After all, he is just a scribe, and at best he is a staff member.

And people who are good at math ......

With his unparalleled mathematical skills and superhuman political skills, the Marquis of Beiping assisted Emperor Taizong Xiaowen for fifteen years, and pulled the Han family out of the abyss of decay, chaos and poverty!

When he paid homage to the prime minister, the Xiongnu crisscrossed Henan.

All nations are caught in fire and water.

The three princes and nine ministers of the imperial court, even the last dynasty had to bear ox carts.

The army of the country was hungry on the border, and some soldiers could not stand it anymore, so they fed themselves with bark and even clay.

When he left the phase.

In the treasury of the imperial court, grain and copper coins are piled up.

There was even a rope for stringing money that rotted in the treasury.

The border army was well fed and clothed, and the Han army even began to form a local containment of the Hun cavalry.

The people live and work in peace and contentment, and the world's businessmen are rich and rich, and they emerge in endlessly.

There are rich merchants and even thousands of slaves, and they travel like princes!

The country has even begun to have the strength to build pastures and accumulate horses in the north!

Even in the world, the ministers who are good at mathematics are all important ministers of the state.

The most obvious example is the lord Duwei Sang Hongyang.

Don't look at the countless Confucian scholars shouting every day: Please cook Hong sheep!

It seems that Sang Hong sheep is not dead, and the society is difficult to be safe!

But...... As long as anyone with a brain knows, the Han family has been able to persist in the long war of using troops abroad for many years and costing incalculably.

It all relied on Sang Hongyang and his salt and iron yamen.

Without the income from salt and iron, the state finances would have collapsed long ago!

"I heard that this Zhang Sheng has not yet been married?" Someone's eyes rolled, and he suddenly had an idea in his heart: "I have a fine gentleman, and I should be worthy of this son!" ”

Such a talent with a hidden dragon in the abyss, if he didn't want to pull it into his own house, then these nobles would be considered to be in vain for so many years.

Even Yuan Chang was stunned.

"What this son said is true......" he opened his mouth wide and looked incredulous.

Then, he slapped his palms.

"This one is so cool......"

"This kind of pretending pose is so beautiful......"

"I'm going to learn ...... too"

Oh, yes......

Compared with this Zhang Zizhong, he used to rely on wealth and retinue to pretend to be forced, which was too low.

Look at the people!

This shot shocked the audience, and everyone's eyes were full of reverence.

If you can do the same yourself......

Wouldn't that be much cooler than it is now?

No, at least 10,000 times cooler!

……………………………………

Xu Hui looked at the scholars around him, and then at the noble son of the Yuan family behind him.

In my heart, I almost fell into a state of despair.

He knew very well that today's events would be preached.

Since then, his Xu Hui's name has been directly linked to this sub-weight.

When others mention him, they will say: Xu Hui, I know, isn't it the Taiyuan scholar who was easily beaten by Zhang Zizhong?

This reputation is not good at all, and it will seriously affect his future career!

Completely destroy the path he had planned long ago!

What to do?

How can this disadvantage be reversed?

Xu Hui thought about it, and he felt that if he came up with those so-called difficult questions again, I am afraid it would just be to make fun of himself.

If you are broken by this piece of weight again, where will your face go?

Suddenly, a flash of lightning pierced Xu Hui's mind.

"That's it!" Xu Hui clenched his fists.

This question, Xu Hui believes, this Zhang Zizhong will definitely not be able to answer!

Even if he is an immortal, he can't answer!

Because, this topic has plagued Han mathematicians for decades, and countless powerful giants have studied all their lives, but they all end up with regrets!

He squatted down, drew a circle on the ground, then raised his head and asked, "Is this question possible?" ”

"The ratio of its circumference and circumference, may Zhang Sheng give it!"

Pi!

The immortal crown of geometry!

At least for now!

Since the conclusion of the Zhou Sutra, for hundreds of years, countless people with lofty ideals, geniuses and powers, have competed to devote their hearts and minds to this.

Everyone knows that the conclusion of the Zhou Sutra is wrong.

But......

No one can calculate a more precise value than the Circumferential Calculations.

Even, no one can find a better way to calculate it than the Zhou Ji Sutra.

As a result, pi has become the eternal pain of mathematicians all over the world for hundreds of years.

Everyone knows that Zhou Ji is wrong.

But no one can give an exact answer.

There is not even an approximate answer!

Xu Hui didn't believe it!

This humble scholar of Nanling can give the answer!

If you can......

So......

Defeated at the hands of an unearthly genius who solved pi, that was also convincing.

When you go out in the future, you don't have to worry about being pointed at.

After all, it is a shame to lose to passers-by.

But losing to Dong Zi and Hu Zi is a supreme honor!

Not to mention......

Xu Hui never believed that the young man in front of him could solve it, and he could solve pi!

Zhang Yue looked at the circle, then at Xu Hui, and suddenly laughed: "Pi...... It's such a coincidence, and the contemptible people just know ......"

"Three-point-one-four......"

For a more detailed answer...... That's three o'clock one four one five nine two six ......"

In later generations, this is probably the answer that elementary school students can memorize backwards.

"Impossible!" Xu Hui shook his head violently, he felt that the whole world was collapsing.

"You're lying!" Wu Yuan shouted.

Pi, this is pi, a problem that has plagued the world's mathematicians for hundreds of years!

The crown of the field of mathematics!

The unquestionable throne!

"Why is this impossible?" Zhang Yue smiled and said: "When the contemptible man was twelve years old, he had already accurate pi to 3.14......"

Well, that year, the history textbook did tell him the answer.

"When I was eighteen years old, I had already answered this to 3:1416......"

"Some time ago, I went further and got three points, one four, one five, nine and two six......"

"It could be more accurate later, but I'm too lazy to ask for ......"

"Do you believe it?" Zhang Yue stood up, walked in front of Xu Hui, squatted down, and said, "Then I'll tell you, how did you get this answer?" ”

"Circumcision ......"

"Cut the circle continuously, cut it again and again, until finally it can no longer be cut, get one hundred and ninety-two parts, and seek it according to the Pythagorean theorem, you get three points and four......"

"If there is any free time, continue to cut it, and cut it to one thousand five hundred and thirty-six sides, and get a pi rate of three .1416 ......."

The people listened to it with great joy.

Xu Hui is even more hepatobiliary.

Because he found that the other party's method was right and feasible!

It's just that......

Who would be so bored to keep cutting and dividing in a circle?

And such a job must be extremely boring and draining of people's patience.

"After that, I thought it was too boring and boring, so I asked for two values......

"Then divide these two values to get three points one hundred and four one five nine six two ......"

"These two numbers are three hundred and fifty-five and one hundred and thirteen......

"I call it ...... by secret rate"

Standing up, Zhang Yue looked at Xu Hui and asked, "How about my circumcision technique and secret rate, how about looking at it by the king?" ”

Xu Hui was already dumbfounded, and even threw himself to the ground.

Such a solution, such an algorithm.

Although he hadn't calculated it, he knew that such a method would work! It has to be feasible too!

This shows that what the young man in front of him said is right.

He didn't lie!

He solved pi and answered the questions of countless sages over the centuries.

Xu Hui took a deep breath and slowly took three steps back, but bowed for a long time, bowed again, and said: "Zhang Jun is righteous, solve doubts for the world, and restore it to the world!" ”

If you don't accept it, you can't!

In today's world, anyone who can solve pi will surely become famous all over the world!

Because, pi is the crown of mathematics!

In the face of such a great cause, no matter how proud Xu Hui is, he can only bow down!
