All-round mathematician

Chapter 143 The Origins of Calculus
In a certain guest room in New York, there are four people living in the living room.Teacher Qian took the remote control and changed various channels at will, all of which were Western programs and spoke English.

Watching TV is so relaxing, but every time I have to turn a corner in my mind to convert the language into Chinese, Teacher Qian is very uncomfortable and really boring.

The procedures for the Olympiad have been completed, and now we are waiting for the national teams to arrive, and the opening time is still ten days away.

The three students were very self-conscious. Zhang Zhi and Li Jiafan checked the problems on their stomachs. They couldn't leave their homework behind. They still had to spend some time every day and work harder.

What is the male god Yang Fan doing?He finally asked for the wireless password of the hotel, and he had finished filling out the volunteers in school, and he couldn't wait to contact the other side of the ocean.

"What school did Qi Yueshu apply to?" Yang Fan sent a message to ask his best friend.

"I made some inquiries for you. They seem to be schools in Jiangsu, Zhejiang and Shanghai. She told her classmates that the climate in the north is very uncomfortable." Yuan Wenbo replied quickly.

Yang Fan's heart sank, and he had a very bad premonition.

Although he and Qi Yueshu had never discussed the issue of volunteering, Yang Fan was willing to give her enough trust, thinking that he would choose the capital tacitly.

The result is obvious, separating the two places for four full years.Even if we may encounter each other during Chinese New Year, it is just a normal friendship between classmates.

Young men and women in college rarely fall in love once.Qi Yueshu is not beautiful, but she has a good personality, carefulness, and gentleness. In Yang Fan's heart, she is an ideal candidate for his wife, not just a girlfriend.

"I see, is this your choice?"

He had discovered some problems a long time ago, and he thought that the pressure in the third year of high school was too great, and Yang Fan didn't know how to protect her.

"Do you want to ask directly now?"

After the Chinese New Year, the two interacted less, Yang Fan was also busy, Qi Yueshu became more nervous, and never went out once.

Enter on the phone: Why did you choose to stay in the south, press the send button several times and then retract, he deleted the message.

"I finally found out about this matter, so... so be it."

Yang Fan took a deep breath and was already mentally prepared.

The phone vibrated, and another message from his best friend: "Squad leader Zeng Da heard that he chose East Zhejiang."

"I didn't even ask you, you told me what the hell." Yang Fan secretly hated Yuan Wenbo for being ignorant, and it didn't make him feel worse.

"I just want to tell you that your aura of good fortune has collapsed, and the task in the harem is arduous."

"roll."

Yang Fan gritted his teeth.Others are wandering about being broken in love, and this kind of fucking is also a best friend, don't they know how to comfort that broken heart?

"Xiao Hongye is so mysterious that she doesn't reveal it. No one in the class said anything about it. But, I believe that with your sullen energy, you must have known it in advance. This is going to be a double entry, right? You are eating the food in the bowl like this. Looking at what's in the pot has already aroused the public outrage of the people of the world."

Yuan Wenbo still sprinkled salt on the wound, and Yang Fan's phone was almost crushed: "Lahei, when will you please eat five meals of Mala Tang before resurrecting, bastard."

At this time, the phone in the living room rang, and Teacher Qian turned the volume of the TV to the lowest level and said, "Yang Fan, I must be looking for you."

Among the few people, only Diaosi didn't use a mobile phone, and there were few people around him who used fixed phones to contact them. In the past few days, Li Yunfei's manager came to report the progress every few days.

"Hi, I'm Yang Fan."

"Student Yang Fan, do you have time now? A few masters want to meet." The agent asked.

This made Yang Fan embarrassed. During the Olympiad, it was shameful to go out often.Li Yunfei had talked with Mr. Qian and they just agreed to go out on the last day of the show.

There is no conflict between the performance time and the competition, and it can be adjusted a few days before the question.

"Mr. Qian, can I go out?" Yang Fan asked.

Teacher Qian frowned, hesitated for a while, and then nodded.

"Okay, I have time."

"All right, I'll send a car now, and I'll call a car to pick you up downstairs in an hour."

After the call ended, Yang Fan returned to his seat and took out a physical notebook.

Teacher Qian glanced at the three students, turned off the TV, walked to Yang Fan's side, and glanced at the notes.

After reading a few articles, Teacher Qian was a little displeased, and said, "Yang Fan, the Mathematical Olympiad is the most important thing recently. Your total score in the training camp is the first, but you can't relax, physics is not bad these days."

Yang Fan didn't expect that this would cause the teacher's displeasure, and he couldn't guarantee that the middle school math was perfect. After pondering for a while, he said, "Mr. Qian, just take a look, high school math... I'm actually pretty good at it."

These words were full of confidence, but Teacher Qian frowned. He had no foundation in mathematics, and he was thinking about how to educate the students in front of him.

When he thought of an idea, his eyes lit up, and he said, "The two most famous physicists know about it, right?"

"I know." Yang Fan answered neatly.

Newton and Einstein.

Newton's three theorems of physics, as long as you go to middle school, who doesn't know.

If you don't want to be a god in your later years and study the occult, your status in the history books will be even higher.

Einstein will not talk about it, affecting the direction of world wars.

"Okay, we all know these two great achievements. Now let me tell you a secret. Einstein once said why he entered the field of physics because he was afraid of mathematics. He said that any branch of mathematics, let him A lifetime of research is not enough. Even he, facing mathematics, still trembles."

Teacher Qian is engaged in mathematics education, so of course he supports mathematics.But Einstein really said this to his friends back then.

Yang Fan suddenly developed a reverence for mathematics, and he didn't even dare to go deep into such a great ability. Physics seems to be a bit childish when it comes to mathematics.

"We can't miss it. The development of science must be balanced, so that we can accumulate a lot of money."

The students listened to it a little bit, Teacher Qian smiled, and said, "Why did I mention Newton here? In fact, Newton's status in the mathematics world is equivalent to Einstein's status in modern physics. Newton's intelligence can be said to be seen once in a thousand years."

"What, Newton is also a mathematician? Or a very good mathematician?" Yang Fan was dumbfounded, this news is really exciting.

"The basis of modern advanced mathematics is calculus, and this concept did not appear until Newton wrote "Fluency and Infinite Series" in 1671. This book was not published until 1736."

"Calculus and calculus are actually two concepts. Newton established differential calculus more than 300 years ago, and another mathematician Leibniz proposed integral calculus at about the same time. This is the origin of modern calculus. It can be said that , these two are the fathers of modern mathematics."

"The emergence of this theory can be said to have promoted the development of mathematics, and it is not an exaggeration to put the two of them in high status."

"The things we learn in mathematics in our university are actually left over from what they played 300 years ago. When you are a graduate student or doctoral student, you only learn mathematics in the last 200 years. With more and more branches of numbers , Ordinary people spend their entire lives without being able to enter the threshold, and even geniuses can only excel in two or three fields. Therefore, Yang Fan, you must be in awe of mathematics."

These words also fell on the minds of the two students who were doing their homework.

The three students felt like they were looking up at the mountains. Mathematics is really difficult.
