There is a strange phenomenon in mathematics, that is, the simpler the problem, the more difficult it is to solve. In the final analysis, it is because mathematics is not a natural science, and its research object is not physical objects, but abstract concepts.

Mathematics is a science, a formal science among sciences, and its underlying logic is constructed based on the arithmetic axiom system of Peano's axioms.

This leads to a problem. When it comes to the most basic number theory proofs, mathematics seems particularly weak.

For example, some people think that 11=2 is very simple for a three-year-old child, but mathematician Russell's masterpiece Principia Mathematica took more than 300 pages to prove 11=2!

Looking at the mathematicians who have left their names in the history of mathematics, they can be divided into two categories:

One type is mathematicians who are good at asking questions and proposing new mathematical theories in the process of solving problems.

The other type is those who are only responsible for creating problems and do not care about killing or burying them.

The German mathematician Christian Goldbach obviously fell into the latter category. In 1742, he proposed two Goldbach's conjectures.

That's right, Goldbach's conjecture was originally composed of two conjectures, called the odd-numbered Goldbach's conjecture and the even-numbered Goldbach's conjecture.

Goldbach's conjecture for odd numbers states that any odd number not less than 7 can be expressed as the sum of three prime numbers; for even numbers Goldbach's conjecture states that any even number not less than 4 can be expressed as the sum of two prime numbers (this is actually 11

origin of the name).

Fortunately, mathematician Vinogradov partially proved the odd Goldbach conjecture, which actually proved that any sufficiently large odd number can be expressed as the sum of three prime numbers.

That is to say, after this, once the even-numbered Goldbach conjecture is proved, the odd-numbered Goldbach conjecture can be perfectly derived.

Therefore, under the habit of "saving paper" among mathematicians, Goldbach's conjecture was simplified to the fact that any even number greater than 2 can be written as the sum of two prime numbers.

Seeing the information collected by the artificial intelligence Xiaohua on the screen, Li Mo showed a bitter smile.

He has tried using hardy and littlewood circle methods to try to solve Goldbach's conjecture. The result is obvious, that is, he completely wasted 3 days. Because there are two variables in Goldbach's conjecture, after proposing one

, the remaining one is difficult to trivially estimate.

After these days of "hard study and constant frustration", Li Mo developed a deep respect for Chen Sheng, a senior mathematician from China. Chen Sheng was able to propose a screening method for almost prime numbers to replace even numbers under difficult circumstances, proving that

"12". This is already very rare, although in Li Mo's opinion, this result is still far away from solving the even number Goldbach's conjecture.

As for the latter, there are many mathematicians who claim to the outside world that they have achieved breakthrough results in proving Goldbach's conjecture, but they have not submitted proof papers for a long time, and some of them have not even given out their ideas, which has no reference value at all.

Li Mo has gradually realized that Goldbach's conjecture is different from the world's difficult problems he has proved before. This is completely a high mountain. When an experienced climber faces a high mountain, the best thing to do is to make preparations at the foot of the mountain.

.

Therefore, he was not in a hurry to "retreat", but instead "exploded" various number theory literature and absorbed the wisdom essence of his predecessors.

"Tuk...tuk..." There was a knock on the door.

Li Mo knew it was Zhang Xiaoli without raising his head, because she was the only one who was so weak when knocking on the door, as if she was afraid of breaking the door.

"Boss, this is the project application for the lab members." Zhang Xiaoli handed over a document, "Also, Bi Mingyu's assessment results have come out, and Dr. Zhou gave it an A rating."

"A? So tall?" Li Mo raised his head. He didn't expect that the seemingly dull man in the plaid shirt was actually full of talent.

Character:9,Professional:a

Such scores are enough to qualify for admission to the laboratory.

"Then let's recruit him and temporarily place him under Dr. Zhou, and he will enjoy the benefits of a regular employee." Li Mo explained.

"Does he also need to be allocated a set of welfare housing in Xiushan?" Zhang Xiaoli then asked.

Li Mo frowned.

Considering that the housing prices in Yanjing are extremely high, in order to solve the worries of employees, during the construction of the new experiment, he deliberately planned more than a dozen family buildings outside the laboratory, near Xiushan Park, and each laboratory employee

A regular employee will be able to obtain the long-term right to use a house. If the employee has worked for more than ten years or made a significant contribution, the ownership of the house will be completely owned by the employee.

"Give him a two-bedroom apartment. He doesn't seem to be married yet." After thinking for a moment, Li Mo made a decision.

"Okay, I'll make arrangements right now."

Li Mo looked at the project application form in his hand. Since the project was currently in a window period, he allowed the experimenters to freely choose new projects according to their own hobbies.

Stones from other mountains can be used to attack jade, and sometimes an accidental discovery in the laboratory may lead to a great invention.

Scottish scientist Sir Alexander Fleming noticed a rapidly growing mold that prevented bacterial growth in a discarded petri dish, so he isolated the mold and cultured it separately, and used penicillin, which saved countless people.

Electrical engineer John Hopp, in the middle of the last century, tried to use radio frequency heating to increase body temperature. He found that electrical pulses did not have much effect on body heat, but they could stimulate the heart and change its rhythm again, so he invented the pacemaker.

Let’s take a look at what good project proposals the outstanding scientists in the laboratory have. Li Mo is full of expectations for the “wisdom of the people”.

"Using "helium gas voice change" to study the role of resonance in elephant vocalizations, applicants: Zhou Mingrui, Liu Xuanchen, Liu Hao."

"Study on how and why koalas excrete square feces. Applicants: Wang Xiaochuan and Liu Lei."

"Detection of fly contamination of red wine - pheromones that transmit information between flies can be smelled by the human nose. Guests cannot smell the pheromones until they are a little drunk. Applicant: Jingjing."

"What will happen to mathematics when 11=3? Applicant: Zhou Dafang."

.......

Damn it, what kind of weird topic selection are these? Li Mo felt that his eyes were stung. Are these seemingly honest and dull experimenters so boring inside?

Who are the elephants and the koalas provoking?

There is also a quiet "fly experiment". Is this the rhythm of preparing to open a small red wine workshop?

As for Zhou Dafang's 11=3, Li Mo was speechless. This guy has had enough of orthodox mathematics and is ready to develop into the field of civil sciences? Doesn't he understand that for mathematics, numbers are not important, what is important is the logic.
