Chapter 290 Who knows where this theorem came from?
Ding Sihan and Qu Wanqiu, who seemed to be selling themselves, have also arrived. Chen Yuying is the last one to arrive today.
"Why did you two come together?" Ding Sihan narrowed his eyes and turned into a melon-eating civet.
"We just happened to meet downstairs." Lin Li replied.
"I don't believe it." Ding Sihan snorted coldly.
"We just happened to meet downstairs." Chen Yuying also replied.
"Oh, that's how it is." Ding Sihan nodded.
Lin Li: "?"
This civet really owes Runtu.
While taking out all the school supplies and placing them on the table, Lin Li looked up at Ding Sihan opposite him and asked:
"Little Dingding, what are you going to eat for lunch today? Have you chosen it?"
"Aren't you treating us today? You let me choose the restaurant? Don't you choose it yourself?" Ding Sihan asked back.
Today is to thank you for the surprise on my birthday, so Lin Li paid for both lunch and dinner.
Lin Li asked for it himself.
I was originally planning to find a place to relax, but in the end, I thought about preparing for the exam and decided to forget it. I will make up for it later if I have the chance.
Hearing what Ding Sihan said, Lin Li nodded: "Okay, then let's go to Chishi together. Bufan introduced me to a newly opened toilet nearby, which is crowded."
Straight to the chest.
"Go away, I'll choose it. You guy, at least say Shaxian!"
Facing the greedy cat Lin Li, Ding Sihan and Qu Wanqiu were stunned at first, then put their fists on their foreheads, and couldn't help shaking their heads and complaining.
People who have been with Bai Bufan for a long time, as expected, habits will still be contagious.
"I didn't introduce it, I usually go to the old one!" Bai Bufan was also indignant.
"Then I'll introduce this one to you next time."
"Okay, thank you."
"What budget?" Ding Sihan asked Lin Li without participating in the wise topic of these two idiots.
"It depends on whether you have shame or not. If you don't have shame, there is no limit." Lin Li said casually.
"I understand."
"Price sorting, from high to low..."
"There's only one Michelin Xiling restaurant? It's so far away? You have to pay for the taxi yourself."
"This half-head abalone costs 11,000 to 13,000 yuan. How about we each have one to try? But save some money for Lin Li, we'll eat something of lower quality, the 11,000 yuan range will do."
"..."
Ding Sihan and Qu Wanqiu were mumbling across the street, excited.
Lin Li smiled.
Is the budget already 60,000 yuan? "Lin Li, where are you going?" Ding Sihan looked at Lin Li who stood up and asked in confusion. "To the toilet." "Then why did you take all the things with you?" "Of course it's because
Confucius said that if you learn without shitting, you will be lost, and if you don't learn, you will be in danger, so shitting and learning need to be combined, not that I'm going to run away and delete all of you at home, how could it be possible, I can't do such a thing." Lin Li said innocently. "Okay, come back, I just chose a restaurant recommended online, with an average of more than 40 yuan per person." Ding Sihan listened to this long and difficult sentence, smiled with satisfaction and nodded, showing his mobile phone. Lin Li knew that Ding Sihan was joking, but he still let out a long sigh and sat back in his seat. It was only eleven o'clock now, and although Ding Qubai probably hadn't had breakfast yet, there was no need to go to lunch so early. So after the joke, everyone quickly entered the learning stage. Carrying the expectations of Wang Yuezhi and Chen Yuying, Lin Li had a reason not to lose! "You are studying and listening to the driving school online class at the same time? Can you study?" Bai Bufan was about to ask Lin Li a question, and after noticing Lin Li's current situation, he asked in surprise. Lin Li was wearing an earphone, with the test paper in front of him, but there was also a standing mobile phone in front of the test paper, playing a video. "Why can't I study? Just study normally." Lin Li shrugged. The sound in the earphone was actually very small. Lin Li only needed to take a photo of his ID card and take a photo of the phone when the reminder to take a photo to punch in popped up. "I admire people who can do two things at once. I dare not listen to music when I study. Damn, when the last homework asked me to write about the Six Gentlemen of the Wuxu Reform, I was playing We Like You by Times Circus in my headphones, but I ended up writing Ma Jiaqi and Ding Chengxin. Alas, the first thing Sister Zhen asked me in the office was, "Didn't you notice there's one more person?" " There are five of the Four Heavenly Kings. This is common sense. Didn't you tell the history teacher?" Lin Li laughed and teased. The phone popped up a test, and he picked up the ID card and smiled. The test passed, and the online class continued. "Hey, Lin Li, why is the photo on your ID card so childish?" Bai Bufan reached out and snatched the ID card after the class ended, looking at Lin Li's head on it and teasing, "You don't look like you now." "It was taken three years ago, it definitely doesn't look like you." Lin Li replied indifferently. Men change a lot when they grow up. "Let me see it too." Ding Sihan stretched out his hand curiously. "But your ID card looks exactly like someone I know. "After Lin Li nodded, Bai Bufan handed the ID card to Ding Sihan, and then he said to Lin Li. "Who?" "My son." Lin Li laughed. Everyone, just like he just showed, Lin Li can do two things at the same time. So Lin Li lost his reason and calmness at the same time.
Bai Bufan lost his pulse and breath.
...
It was near noon.
The sunlight outside the study room had turned into a rich orange-yellow color, and it shone through the gaps in the curtains into the study room, making it warm.
Unfortunately, despite this, Chen Yuying was still unwilling to take off her windbreaker and let Lin Li take a closer look at her curves.
Xiling was still too far away from Chaoxian, and the sun was not shining warmly enough.
Chaoxian, bad!
"Almost done, let's eat?" After reviewing a lesson, Ding Sihan raised his hands and hummed softly, looked at the time, and looked up to ask everyone.
"Okay."
"Let's go."
Everyone nodded, but Bai Bufan was focused, writing quickly on the paper. When he heard the sound, he just raised his left hand slightly and said "wait a minute" without raising his head.
Then he immediately put it down and continued to press the straw paper, and his face became more and more excited.
"No hurry, take your time."
Seeing this, Lin Li sat down again, opened the water cup and started drinking water.
This kind of learning zone state is also rare. After a look, he was indeed doing math problems.
At this time, as long as the solution is found, it will be of great benefit to Bai Bufan.
Bai Bufan did not let Lin Li down. The next second, he stood up excitedly, slammed his pen heavily on the draft paper, and said excitedly:
"I proved it! Hey! I proved it!"
"Evil beast, what did you prove?"
"The Pythagorean theorem is wrong!"
"Yes, poof--" Lin Li's thumb was already erected, but the next second after confirming that he heard something, the water sprayed out instantly.
Fortunately, it was Bai Bufan who was facing him, not the girls.
Bai Bufan's excitement came to an abrupt end. He wiped the water off his face and looked at Lin Li coldly.
He was molested.
But Lin Li didn't have time to care about this now. He pointed his finger at Bai Bufan with disbelief on his face: "What did you just say? What did you prove to be wrong?"
Bai Bufan, who was originally preparing to question Lin Li, didn't care about the water on his face after hearing this. He took the paper handed by Chen Yuying and wiped it a few times, then excitedly showed his draft paper to the four people present.
He made a solemn declaration:
"The Pythagorean theorem may not be true!"
"I know you may not believe it, but listen to me carefully!"
"Come, follow my pace, we use the method of contradiction. First, we assume that a+b=c is correct. abc is just an alphabetic algebra and can be set arbitrarily. So, to make it easier for you to understand, we write it as x+y=z.
Hey, you smart people should be able to see it by now."
"What did you see?"
"Alas, stupid!
Then I have to continue to reveal it. Look! The left side x+y is a quadratic equation, while the right side z is a quadratic equation.
A quadratic equation is also a linear equation, but a quadratic equation is only fifty cents.
The price difference is twice, everyone. This is obviously not equal, so the assumption is not true, which means that the Pythagorean theorem is incorrect!"
Since the entire proof was thought out by himself, Bai Bufan's explanation was very smooth and flowing.
Ding Sihan, Chen Yuying, Qu Wanqiu: "?"
What is Wumao?
What did you just hear?
Bai Bufan shook his head. His shocking discovery really shocked Lin, Ding, Qu and Chen. They stared at the formula on their draft paper and couldn't say a word.
It's understandable.
After all, his discovery was too great.
Lin Li was the first to react. He covered his mouth with a look of horror: "Fuck, so it's like this..."
Ding Sihan, Chen Yuying, Qu Wanqiu: "?"
Not... you?
Lin Li then sighed, muttering more resentfully and regretfully:
"Damn it, I recommended the Pythagorean theorem to my friends before, but I didn't expect it to collapse. Everyone remember to avoid it in the future. Old Jiantou is also a big harm to people. Why does he take all business orders and teach all kinds of knowledge..." "Well
... I think it's normal for the collapse to happen. When I was in junior high school, I felt that this theorem was not serious. How can a theorem talk about both the Pythagorean theorem and the Pythagorean theorem? It feels like it became popular by just passing it by."
Ding Sihan took a deep breath, nodded, and agreed.
Chen Yuying and Qu Wanqiu turned their heads sharply: "???"
No... why are you too?
"Not only that, my research results are not over yet, everyone, I just found out the specific value of π."
"Oh, there are still experts?"
"Come, look, π = 兀 = 一 + 儿, and Binbin taught that the erhua sound has no practical meaning, which means π = 一 = 1!"
The great mathematician Bai Bufan would not stop there, he continued to turn over the previous draft paper and popularize science to the few people.
"Fuck! Bai Bufan, you are simply a genius!" Lin Li was simply a perfect supporting role, singing in unison:
"Humanity no longer has to worry about memorizing pi! There is one less dark cloud on the mathematics building! Bai Bufan, you are simply Gauss's brother, a big ditch!"
It seems that all-round development is necessary. If those mathematicians in the past had studied Chinese well, they would have found π long ago.
Ding Sihan also nodded with satisfaction: "Bai Bufan's small step is a step for mankind."
"You're great, you're great."
The atmosphere in the study room was harmonious, with business exaggerations and modesty.
Chen Yuying and Qu Wanqiu looked at each other.
I don't know why, but it seems that they are the only ones who are abnormal among the people present.
So are we the two who are sick?
Not confident, let's see.
"Wanqiu, don't join them, please." Poor Yingbao pulled Qu Wanqiu's hand and begged.
"Don't worry, I'm still a little behind, I'm still too sick." Qu Wanqiu patted the back of Chen Yuying's hand and nodded regretfully.
"Bufan, are you interested in teaching in the mountain villages during the winter and summer vacations? I feel like you can teach the children in the mountains into the jungle."
Lin Li hooked Bai Bufan's shoulder and treated him as a national hero——
"Bufan, the country needs a gentleman like you!"
"Tsk——Fuck——" Bai Bufan still wanted to remain serious, but Lin Li's two words completely made him unable to hold back, so he laughed out loud.
At this time, Lin Li stopped acting and changed his expression instantly. He kicked Bai Bufan's butt with a side kick and scolded with a smile:
"Damn idiot, Bai Bufan, what the hell are you learning this morning? Is this how proof by contradiction is used? Proof by contradiction = it doesn't hold anyway, right?"
"Just tell me if it's right or not?"
"Since equations are 50 cents each, what else can I say? I'll just obey you."
"Hahaha, there's nothing I can do. When I was doing math problems, my thoughts diverged and it turned out like this." Bai Bufan couldn't hold it anymore and responded with a smile.
"Come on, let's go and have dinner."
"Let's go."
...
The five of them still took two taxis to the restaurant that Ding Sihan posted in the group. Lin Li and Bai Bufan arrived first.
It can be seen that it is a restaurant with good reviews because it is full of people and there are two people sitting on the chairs placed on the street outside. They should be queuing.
However, Ding Sihan said that she had already made a reservation, so Lin Li walked in directly.
"Hello, the seats are full now. You need to queue up."
"We have made reservations. Ms. Ding called."
"Oh, I remember. There are reservations. Can you please go to that table first? The table has not been cleaned yet. Please wait a moment." The receptionist pointed to an empty table that had not been cleaned yet and said apologetically.
The two of them had no problem and walked to the seat next to the half-floor window.
"There are only four chairs." Bai Bufan pointed at the number of chairs and called out.
"I have a plan. The chair can only seat one person when it is placed upright, but it can seat four people when the four legs are placed backward. How about we sit in one and the three of them sit in three?" Lin Li always had a lot of ideas.
"Go away!" Bai Bufan covered his buttocks, which sounded a little painful, and laughed and scolded, "You can torture yourself instead of me. Why don't you ask the waiter for another one?"
Bai Bufan waved to the waiter, but he seemed to be too busy and did not respond for the time being.
"Do it yourself and have enough food and clothing." Lin Li stood up.
"Hello, beautiful lady, are you eating alone?"
Hearing such a greasy and earthy way of chatting up, the woman sitting at the long single-sided table against the wall frowned and turned her head away.
The moment she saw Lin Li's face, her brows immediately relaxed.
Remember, chatting up a handsome guy is a good encounter, while chatting up an ugly guy is sexual harassment by the goblin.
Especially since Lin Li looks very young and is still a fresh meat.
A perfect dish.
"Ah, yes, I'm alone." The woman tidied her hair shyly, and had already reached out to open WeChat and clicked on her own QR code.
Her shyness came to an abrupt end when she saw Lin Li immediately said thank you happily and moved the empty chair next to her.
Eh?
Looking at Lin Li's briskly leaving back, the woman slowly pressed a question mark.
You're not here to flirt with me!
"Pingping, I'm back, eh, where's my chair?" The bestie who had just finished using the bathroom came back and was stunned when she saw the empty ground.
When the woman noticed that Lin Li also looked over here after hearing her bestie's voice, and stood up again, and seemed to be hesitating whether to return the chair he had just brought here...
Now it was not a question mark, but a three-bedroom, one-living-room apartment.
It was so embarrassing that I got goosebumps.
Instantly, she chose to stand up, hugged her best friend and walked out, while lowering her voice to plead: "Let's go! Let's go! Let's go to another restaurant!"
"Ah? Why?"
"Don't ask first! Let's go, let's go first! Please!"
Best friend: "?"
...
"Should I not have taken this chair?" Lin Li asked Bai Bufan.
"It doesn't matter now, anyway, they are gone now." Bai Bufan said with a smile.
Soon, the taxi that Chen Yuying and the others took arrived.
The five people were all there, and the table had been cleaned up long ago, so they scanned the code to order food.
"Click."
Bai Bufan's outstretched hand was hit red by Lin Li's chopsticks.
"You guy, you forgot the rules again." Lin Li said coldly.
"No, what did I do?" Bai Bufan looked puzzled.
"Don't you understand the principle of eating with your phone first?" Lin Li raised his chin.
"Oh, my."
Bai Bufan and girls of the same age have rarely been out together. The last time was still this group, so it was normal for them to forget.
"Oh, my" is over? Bai Bufan, what is your attitude? "Lin Li, who couldn't move his chopsticks and had no interest in taking pictures, still refused to let Bai Bufan go, and asked in a cold voice:
"When we had no food, who found a restaurant for us? Bai Bufan! When we had no money to pay the bill, who paid for us? ! The mobile phone paid for us and gave us navigation, but you picked up your chopsticks first?
You still have this attitude after I told you? Really, you are so disrespectful!"
Bai Bufan: "..."
Your mother.
Are you so exaggerated?
But Bai Bufan immediately bowed slightly to Lin Li, and apologized solemnly and heavily: "I'm sorry, I know I was wrong. Do you have the Douyin account of your mobile phone? I want to write a short essay to thank it. "
"The Douyin account has not been activated yet, but I have its payment code. You can just transfer it to it. Here." Lin Li opened the payment code and showed it to Bai Bufan, indicating that he could start thanking.
Bai Bufan: "?"
"This is your fucking payment code!"
"It's for the mobile phone. "
"..."
The three girls laughed crisply, but after being teased by the two, they decided not to take pictures anymore.
"Okay, okay, stop taking pictures and start eating." Chen Yuying said with a smile.
"Bufan, you can start eating now. You've been very good today, so I'll reward you with the first bite."
"Thanks... No, why do I feel like you're training a dog?"
"Remove the 'why do I feel', ok."
