Compared with the work of analyzing the genetic mechanism, it is much easier to study the process of hijacking immune proteins. As long as you keep designing experiments, keep observing, and add a lot of data support...

The conditions are there.

With enough conditions in place, the Contact Rate can be used to refine the process.

So after the research enters this stage, he can actually relax, just wait for the design of the experiment, collect the data, occasionally go to see the experiment process, and slowly accumulate the 'conditions'.

Instead, Zhao Yi's mind was on another study.

Fermat guessed.

When listening to Ai Lixin's experimental design and planning, he was inspired by the phrase "design experiments separately, observe and accumulate data".

"Separate design?"

"Separate arguments?"

"It is very difficult to prove the Fermat conjecture as a whole. Can it be proved separately?"

Chapter 319 Professor Zhao's first lecture

Many famous mathematical conjectures in the world start from special case arguments. The so-called "special case argument" is an argument for a number or area with a special value. The same is true for Fermat's conjecture at the beginning.

The content of Fermat's conjecture is very simple -

When the integer n is greater than 2, the equation x to the nth power + y to the nth power is equal to z to the nth power has no positive integer solution.

The equation also contains four unknowns, x, y, and z are fixed unknowns, and the special case argument is generally aimed at the power value n.

Euler, a famous Swiss mathematician, was the first to prove Fermat’s conjecture. In a letter to Goldbach, he said that he had proved Fermat’s conjecture when n=3. His proof was published 13 years later in In the book "Guide to Algebra", the method is the "infinite descent method" and the unique factorization theorem shaped like a number system. This method has also been cited many times by later generations.

In 1816, the Paris Academy of Sciences simplified the Fermat conjecture to the case where n is an odd prime number (all prime numbers except 2), that is to say, as long as it can be proved that n is an odd prime number, the Fermat conjecture can be proved to be true .

Later, many mathematicians participated in the proof of Fermat's conjecture, and completed the special cases 'n=3', 'n=5', 'n=7', and even Kummer used the change of 'ideal prime number' to prove the ' For all prime exponents n less than 100, Fermat's last theorem holds'.

This is the most significant breakthrough of the Fermat conjecture in the nineteenth century.

For the next 150 years, Fermat's conjecture did not continue to break through, until the British mathematician Wiles announced the proof of Fermat's conjecture.

At the International Conference of Mathematicians, Zhao Yi used the Riemann conjecture to link the logic of Wiles' proof to explain the logical error of Wiles' proof process.

So far, Fermat's conjecture has become an unsolved mystery.

Zhao Yi thought about the Fermat conjecture for a long time before, and found that it is very difficult to carry out a direct overall proof like Wiles, and it is difficult to advance to all prime numbers with a special case argument for n.

For example, continue to move forward and prove that in the case of n=101, Fermat's conjecture is true.

This is indeed an improvement, but the magnitude of the improvement is very small.

The proof for n=101 can only explain the situation of 101, and the value of n is infinitely many, so the Fermat conjecture cannot be proved.

"If it is a special case argument, why not choose the variables x and y?"

"X and y are indeed random numbers, but they also have merits."

Zhao Yi looked at the Fermat conjecture on the manuscript and thought carefully, "If we can prove that both x and y are odd prime numbers, it may be extended to all numbers."

"First of all, we have to prove the process."

He thought about it and began to write, "Assume that x and y are both odd prime numbers..."

Prime numbers are magic numbers.

All numbers can be regarded as evolved on the basis of prime numbers. For example, an even number can be regarded as the sum of two prime numbers, which is now Goldbach's theorem.

At the same time, any sufficiently large odd number can be written in the form of "3+even number", which can be regarded as the sum of three prime numbers.

"As long as it is proved that x and y are odd prime numbers, it may be extended to all numbers."

"As for the special case of 2, it is easy to discuss."

"After completing this proof, the Fermat conjecture can be simplified..."

……

Although there is an idea to simplify Fermat's conjecture, sometimes the idea that arises suddenly may not be correct, let alone be proved.

Zhao Yi consumed a lot of brain cells and found that the more he thought about the problem, the more complicated it became. He somewhat understood why Wiles' thesis was so complicated that there were more than 100 pages of proofs, and he wanted to really think deeply.

Fermat's conjecture is really very, very complicated when you think about it in depth.

He felt that returning to normal life, he still had time to think about it, and he couldn't delay his life because of research.

Here comes the second week.

The course "Overview of Particle Boundary Theory" is arranged on Tuesday evenings in the large classroom of the Faculty of Science Building.

Zhao Yi felt a little nervous that day, and was a little absent-minded in class in the afternoon, always thinking about the lecture, and made a small correction with Qian Hong on the lesson plan that had been sorted out.

After dinner, he went back to the dormitory to rest for a while. He checked that there was still half an hour left. He also took out the lesson plan and looked at it again. It felt like he was facing an exam.

Fan Lei's reminder sounded from the side, "Zhao Yi, it's almost time, get ready!"

"Correct!"

Li Renzhe followed, "Today is a big day, didn't you say you still need to wear a suit?"

"Put it on and see it!"

Zhao Yi usually wears sportswear, no different from other students. Even when he is giving speeches, most of them are dressed in casual clothes. This is the first time he wears a suit. He mainly considers distinguishing himself from the students. After all, he is the first As a teacher for the first time, it is better to dress appropriately.

Under the urging of Li Renzhe and Fan Lei, Zhao Yi changed into a suit. It was just a casual suit, but it still looked very stylish when the clothes were trimmed.

Zhao Yi took a look in the mirror and was very satisfied with his outfit.

After getting dressed, the few of them went out together and strolled to class.

On the road.

Zhao Yi was dressed in a suit, but he was a little more low-key than usual. Some people who knew him didn't notice it from a distance, but made several passing girls turn their heads neatly.

"So that's Zhao Yi!"

"I looked carefully and saw that today's clothes are really stylish! By the way, he seems to be going to class. I noticed that his class is tonight!"

"The two ordinary-looking people next to him are his roommates..."

The voices of the girls' discussions were not low, and they were heard by Zhao Yi and the others from a distance.

Zhao Yi felt very relieved.

Fan Lei didn't care.

Li Renzhe glanced over depressedly, and said dissatisfied, "You still say we are ordinary? It's just that I don't wear a suit, otherwise I must be more handsome than Zhao Yi!"

"At that time, the girls will first look at Zhao Yi, but when they see me next to me, they will immediately lose their eyes..."

"Snapped!"

Fan Lei patted the back of Li Renzhe's head vigorously, "I found out, Lao Li, why are you getting more and more shameless? After talking to Huang Wenqian about a partner..."

"what are you doing!"

Li Renzhe was taken aback and muttered, raised his fist and wanted to fight back, but was stopped by Zhao Yi, "Hurry up and stop making trouble."

"Look, Zhao Yi doesn't care what I said, what a fart!" Li Renzhe continued to walk forward, and said to Fan Lei.

Fan Lei rolled his eyes and said nothing.

Zhao Yi walked with a smile on his face, as if he really didn't care about what he said just now, but his speed was getting slower and slower. When he passed the basketball court, he suggested to watch the game, "Look at that tall guy, he's a good player!" How nice!"

"I can't even make it!"

"How stupid!"

Zhao Yi seems to be immersed in the fun of watching the game.

Fan Lei and Li Renzhe looked at the time, and hurriedly urged, "Zhao Yi, it's almost time, there are still 5 minutes, let's hurry up, it doesn't matter that we are students, today is your first time in class."

"Ok."

Zhao Yi sighed and continued to walk, but they all arrived at the downstairs of the classroom of the Faculty of Science, and if they walked a few minutes slower, they would still arrive.

When he reached the door of the classroom, he checked the time and found that there were still 2 minutes left.

"stop!"

Zhao Yi signaled Fan Lei to go in first, leaving Li Renzhe alone, took him to the window next to him, and sighed softly, "Old Li, to be honest, I'm really nervous."

"Can you share your experience with me? Just talk about it... and Huang Wenqian, that kind of resentment, but also for the sake of sex-blessing to do it... Anyway, that's the kind, how did you persevere?"

"what?"

Li Renzhe thought for a long time before he figured it out.

What Zhao Yi said was a bit 'ugly', as if he and Huang Wenqian were not in true love... Ahem, anyway, Zhao Yi was talking to himself from the bottom of his heart, so he had to say a few words carefully, in case it could help him Woolen cloth?

He said, "That's right, just think about the past, and bite the bullet...Anyway, that's how it is."

"I don't know how to say it."

"But what are you afraid of? This is your first class. Everyone knows that if you have no experience, even if you don't speak well..."

"All right!"

Zhao Yi looked down at his watch and found that the class time had passed, so he immediately interrupted Li Renzhe and said with a smile on his face, "You can go in, let's not be late. This is my first time as a teacher, so I can't be accused of favoritism Cheating, even if you are my roommate..."

"If I'm late, I can't pretend I didn't see it." There was a guilty tone in the last words.

Li Renzhe nodded to express his understanding.

The two entered the classroom together.

Zhao Yi walked up to the podium with a smile all over his face. His steps were steady and his expression was relaxed. He could not see the slightest bit of tension. He greeted everyone and introduced himself, "My name is Zhao Yi, Zhao Qian, Sun Li's Zhao , a game, a game of chess."

"Life, human beings, is to make progress in constant games and competitions. I hope that every student can become a winner in the game of life!"

"Hurrah—"

There was a burst of applause from the audience.

After the applause calmed down a bit, Zhao Yi talked about the curriculum, "This is my first time as a teacher and the first time I give a lecture. You all want to get credits, so I will talk about the grades first."

""Overview of Particle Boundary Theory" is a novel mathematical physics course. There is no teaching material for the time being, but after this class, the content materials of the next class will be distributed to each student. Take some as test content."

"Exam scores account for [-]% of the total score, and usual scores account for [-]%."

"I don't leave homework for this course, everyone just needs to understand the content, especially non-science students, understand the theory of science, broaden their horizons and knowledge, and do this."

"The usual score is roll call in class. There are ten lessons in total. I will roll call twice. The usual score is the full score."

"Today is the first time."

"By the way, I would like to remind you that it is very troublesome to record lateness and absenteeism. I also hope that the course assistant, Teacher Qian Hong, can work a little easier." Zhao Yi said and pointed to Qian Hong next to the first row, as if everything He was thinking about her.

Qian Hong quickly stood up and turned around to say hello to everyone.

"correct!"

After Zhao Yi finished speaking, he made a special reminder, "Not only being late is the same as being absent from class, but being late for a minute or a few seconds is also late."

"I remember all the students who were late just now."

"Start the roll call!"

"Shh!"

As soon as Zhao Yi's voice fell, many people looked at Li Renzhe, because it was Zhao Yi's first class, and most of the students came in advance, and they all saw Li Renzhe and Zhao Yi entering the door together. I pinch the class time, but I must be late.

Li Renzhe also realized it, but the panic in his heart was calmed down immediately, and he muttered to the student who turned his head, "What are you looking at! Zhao Yi and I live in the same dormitory, can he deduct points from me?"

"Oh~"

The students in the front row said nothing.

Think about it too.

Li Renzhe is Zhao Yi's roommate, and the classroom with Zhao Yi must not be considered late.

but……

It seems that Li Renzhe was the only one who was late just now?

Chapter 3: The Mathematics Legacy of the Unlucky Ghost

on the podium.

Zhao Yi looked at the list of students in his hand and began to enter the roll call mode. He thought that he would call the names according to the list like other teachers, but when he looked up at the classroom, he realized something was wrong.
