Rising: Ten Thousand Years Chapter 3: : pi

When I wake up, it seems like a lifetime away.

Li Zhen lay on the sand and took a deep breath of air, feeling a little lost.

We met a year ago, and now we know each other. I don't know if it counts as love.

But it always feels short-lived. Will always miss her. But I can't remember her last name.

She taught Li Zhen too much knowledge. In order to teach Li Zhen more knowledge, she changed from a poor student to the first in the whole grade...

Sixteen-year-old Li Zhen has never been in love, he is addicted, and he is really moved by humble feelings. It was the girl in the dream, the girl who lived in the age of heaven in ancient times.

After a year, Li Zhen couldn't even tell whether the world he lived in was real or not. Because the dream was so realistic, it was as if I was in this world during the day, but at night, I went to another world...

"Why was that just a dream?"

Sighing lightly, the sockets of her eyes became more and more red.

But what's your last name? Next time I will definitely ask, will write it down, and remember it forever.

————

When I wake up, it seems like a lifetime away.

Zhang Zhi sat in the warm bedroom under the air conditioner, on the soft bed, smoothed his long hair in the shawl, and his almond eyes were covered with mist.

The sense of loss of interest is very strong.

Miss him.

In one year, for him, I changed a lot. From a poor student like a gangster, he became the number one in the school. For him, thank him too.

I also thank him for bringing magnificent waves to my life. I have never been so looking forward to going to bed at eleven o'clock...

In the dream, it is another life.

"Why is that just a dream... Is it possible to meet?"

Zhang Zhi murmured, raised his head, tears dripped down, and fell on the luxurious velvet quilt, printing **** of water.

There was a knock on the door.

"Go to school!"

"Got it, Dad, I'm getting up."

Zhang Zhi quickly wiped away his tears and flicked his long hair, adjusting his sad expression.

Brushing your teeth, washing your face, and riding to school in the car, you kept murmuring absentmindedly: But what's your last name?

Really... what true?

Next time I will definitely ask, I will write it down, and I will write it down.

Early in the morning, the public high school started again.

Yesterday, I mainly talked about history.

But today, I mainly talk about mathematics.

For Li Chen, who has learned calculus in mathematics, the mathematics in public high schools is really at the elementary school level. When the teachers at the school were still using formulas to calculate X with their 'fingers', Li Chen could already solve all the existing math problems in an instant.

This day is used to get money quickly. The college entrance examination starts in ten days. That is my top priority, I have to take the exam, I have to pass the exam.

Even once analyzed the importance of the college entrance examination to Li Chen during the 10,000-year period of the new calendar.

In this era, imperial power reappeared, and the entire country was completely controlled by the hereditary system of centralized power. Therefore, the largest resources in society are not distributed, but centralized, and most interests are in the hands of a few people.

And entering a university that is highly valued by the empire is the only choice to get ahead. Only the talents who become the empire can be taken care of by the empire. Only after you have mastered most of the benefits, can you use these things to spread the knowledge you have mastered with greater efficiency.

Money is the only problem. In the 10,000 years of the new calendar, the problem of corruption is more serious than imagined.

The rich are extremely rich, and the poor are extremely poor. The gap between rich and poor is quite large.

Early in the morning, Li Zhen came out to pick up garbage again with his back bag on his back, looking for waste products.

By noon, a basket full of metal products, waste paper, and plastic products had been harvested. It is mainly these things that can be sold for money.

"Why didn't you go to school today?"

The female owner of the scrap yard laughed.

Li Zhen said: "Today's class is boring, why don't you come out and earn some money."

"Hahaha, didn't you threaten to go to the college entrance examination? Are you impetuous now?"

"Hehe. Not really."

“…”

Without too much explanation, Li Zhen went to Qiantang Valley with his back on his back.

In the middle of the day, I harvested another bag, but I was already exhausted. He hasn't eaten all day, and now his hungry chest is sticking to his back, which is really painful.

Under the scorching sun, he almost collapsed, so he found a cool place to rest.

He was really not willing to spend money to buy some food, but just picked up some leftovers from the garbage dump, but still edible things to satisfy his hunger.

'Shushasha'

Lying on his side in a cool place, but not sleeping. Instead, I picked up a black tile and wrote and drew on the ground.

After a while, a large area of ​​numbers was written on the ground.

Pi!

After this new calendar, the concept has never been raised again.

Li Chen has been calculating pi for several months, and is closer to the culture of ancient times than contemporary people. Li Chen knows the future use of pi better than anyone else.

"To say the least, pi is an unsolved mathematical mystery that could not be solved in their time. It is not expected to be able to solve this mystery, but its use is extremely great."

"Now no one can accurately calculate the area of ​​a circle, but the area of ​​a circle can be calculated with pi. Astronomers can't figure out the area and size of a planet, but pi can be calculated. They can even cooperate with Calculus gives planetary orbits."

"I heard that the professors of Fuxing University want to restore the calculators of ancient times. I have said that I want to know whether the calculation results of the calculator are accurate. I must study pi. Before entering the university, if I calculate After 10,000 digits of pi, many problems will be solved..."

Constantly list lines of arithmetic formulas on the ground, and constantly write Arabic numerals and symbols on the ground with tiles.

As soon as he calculates pi, he will be easily addicted to it, and time will pass quickly without knowing it. It was already afternoon in a blink of an eye.

"3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651..."

Fascinated, he kept writing numbers on the ground in a daze, and kept calculating.

For a concept that has never been mentioned in this era, Li Chen is doing mental and oral calculations.

I have been calculating pi several months ago, and now, Li Chen has calculated more than 3,700 decimal places...

What Li Zhen didn't know was that an hour ago, an old man wearing reading glasses stood behind him, staring blankly at Li Zhen who was lying on the ground and kept counting.

Li Zhen calculated here for several hours without knowing it, but he still didn't find anyone behind him.

Calculating pi is now a hobby, and it is also paving the way for the future. As soon as he has time, Li Zhen will continue to calculate later.

Tired of picking up scraps, he said he lay down here to rest, but he couldn't rest at all.

'cough cough'

The old man had a itchy throat and coughed, which woke Li Zhen up instantly.

Looking back, Li Zhen exclaimed, "Teacher Wang!"

This is the math teacher in the public high school, surnamed Wang.

Teacher Wang pushed the reading glasses and said with a smile: "You didn't have class today. I heard from my classmates that you were picking up trash in Qiantang Valley, so I came out to look for you."

"Huh?"

Li Zhen was a little flattered: "Please trouble Teacher Wang to come to me, this..."

"I am heartbroken. I heard that you made some amazing remarks in history class yesterday. I am looking forward to class today, and I want to ask you a few more questions. But you didn't come, so I came out to find you .Because after hearing your remarks yesterday, I feel that you are not as simple as I thought before, and I have placed hope in your college entrance examination. Unexpectedly, like other students, you gave up early..."

Li Zhen sneered, but really didn't know how to answer. He was full of doubts in his heart. In school, he had always had a very low sense of existence. Why did he bother Mr. Wang to look for it? Before that, Li Zhen even thought that Teacher Wang didn't even know that there was such a number one student as himself.

"I didn't give up."

"I didn't give up, why did I come to pick up trash instead of going to class? The college entrance examination is only ten days away."

"Hehe, nothing."

Teacher Wang took a deep look at Li Zhen, and changed the subject: "What kind of formula did you write? I thought you were writing scribbles~IndoMTL.com~ but I also divided the two numbers. , unexpectedly... can't get the answer. How can there be such a number? It seems that it can never be divided... But it is not the same as dividing 10 by 3. Your number is actually an irrational number and does not repeat. This is unbelievable, what is this number?"

"π"

"Huh? What pie?"

Li Zhen was silent for a while. He was not going to announce the matter of pi right now, so he smiled and said, "I found it by accident, so I don't need to mention it."

Teacher Wang was a little urgent: "Son, you have to tell me, what are these two numbers? Where did they come from? Why did this phenomenon happen? There are thousands of units after the decimal point. There are thousands of them, did you calculate them all? My God, what kind of math genius are you..."

Li Zhen smiled, did not speak for a while, and took out his small notebook. After the more than 3,000 digits calculated before, dozens of numbers were written on it. These dozens of figures were calculated today. Gotta record it.

Then, in a few months, Li Chen has already calculated 3,800 digits of pi... Every day there will be accumulation and progress.

He felt that he would always reach the last 10,000 digits of pi.

After recording the dozens of new numbers obtained today, Li Zhen put the small notebook into his pocket under the eyes of Mr. Wang, and said with a smile: "Then I will deal with these and go back to class. Mr. Wang , the environment here is not good, you should go back to school first."

Teacher Wang pushed his glasses, took another deep look at Li Zhen, turned and left, and said, "Come to school quickly. I have a lot of questions I want to ask you. Other teachers also have a lot of questions. The school also has some questions. Questions and things."
