Rich Devil

173.

Dou is a live broadcast platform.

operation department.

Looking around at the department with dozens of computers, there is a spacious space around it. Dozens of people in the operation department are all seated here. Zhu Haotian stood in front of everyone in the operation department, and said with a cold and stern tone: "Panda The live broadcast platform succeeded! However, its reorganization took us out of the door! We felt that it could not succeed without us, however, it still managed to develop successfully…”

"Now, its success means... I'm a joke with you guys!"

"It symbolizes that the live broadcast platform can still grow smoothly after leaving our operation department..."

"This is my shame, do you feel shame?"

"One will succeed and ten thousand bones will die!"

"I admit that I underestimated that kid before, so this time I won't underestimate the enemy!"

"This time, I won the support of the board of directors of Dou Nai Live, and the network spread smoothly. I decided to take action personally to end my shame. I hope you can also do your best to let that kid know that the Panda Live we created is available at any time. can destroy..."

Having said this, Zhu Haotian's tone paused slightly, and his eyes swept coldly across the people in the operation department.

"Are you confident?!"

"Have!"

Everyone in the operation department looked at Zhu Haotian excitedly, who once brought a panda live broadcast to the rise.

Although he has many shortcomings, no one can deny his strength.

Zhu Haotian still did not show the slightest smile in response to this situation.

It was obvious that he really did his best this time.

"The energy that can be used this time is stronger than the relationship that was barely used before!"

"I want to step on the corpse of Panda Entertainment and regain my foothold on the Dounai live broadcast platform. No one can stop me this time!"

Zhu Haotian glanced at everyone with cold eyes, then waved his hand and said, "Lock the live broadcast room of Shanmeng Haiyan and the live broadcast room of the car to kindergarten, and then wait for the appearance of the rich devil, the local tyrant from this panda live broadcast room, I want to start with him, break down the barriers, and destroy Panda Entertainment in one fell swoop..."

The eyes of the people in the operation department are shining, and the momentum of work is gradually rising...

After entering the working state.

A group of people, like a huge machine turning gears, started according to Zhu Haotian's design.

"Head, we have news from our dark line, the target has appeared."

"Okay, don't act rashly!"

"Wait for him to reward the treasure chest, and then jump over together!"

"The treasure chest has appeared."

"Jump!"

"Hey, 3/5 of the vests have successfully jumped over."

"Report the situation."

"The live broadcast room is Hou Shuge's learning space. Currently, the routine calculation problem of pulling wooden blocks with a trolley is carried out."

"Head, the anchor made a mistake in the first review of the question."

Zhu Haotian's eyes lit up, and he laughed directly, the smile on his face gradually became cruel, "Even God is standing by me, the old rules, the sixth copy, wait for the rich devil to explain, and then carry out the seventh copy, Copy No. 3 is on standby, others are ready to assist Copy No. 3, using Goldbach's conjecture to conjecture the 1+1 project..."

"No. 1 copy, No. 2 copy, No. 4 copy, No. 5 copy, wait until the last one, everyone pushes against the wall, and the funds have been allocated 8 million yuan..."

"no problem!"

…

Audience "uhuuu" in the live broadcast room: "Haha, thanks to the carelessness of the anchor, Newton's second law can continue to be used..."

The audience in the live broadcast room "would like to follow the fate": "Haha, thanks to the carelessness of the anchor, Newton's second law can continue to be used... +1"

The audience in the live broadcast room "Van Gogh loves to paint": "Haha, thanks to the carelessness of the anchor, Newton's second law can continue to be used... +2"

The audience in the live broadcast room "started walking in three years": "Haha, thanks to the carelessness of the anchor, Newton's second law can continue to be used... +3"

The audience in the live broadcast room "Timo don't cry": "Haha, thanks to the carelessness of the anchor, Newton's second law can continue to be used... +10086"

Hu Yanshuo was speechless, these guys are quite photogenic.

Wouldn't it be thanks to Hou Shuge for his carelessness that Newton didn't come up to ask for trouble?

Alright! Big Brother Niu's coffin board was barely pressed.

Hou Shuge, who was on the anchor's screen, scratched his hair, and said somewhat ashamedly: "Sorry, because a mathematical argument has reached a bottleneck recently, I have been unable to keep my spirits up. Such a simple question is wrong."

The audience in the live broadcast room "refreshed and refreshed their minds to find me": "If you can't lift your spirits, you are not strong enough. We sell various legal reminder products such as cigarettes, coffee, tea, etc. Anyone who is interested can contact me!"

The audience in the live room "Zangzhenge": "This can also be advertised? The anchor asked me to provide all kinds of illustrations, including comics, and peripheral derivative audio products. It is absolutely refreshing!"

"Movie Tycoon", the audience in the live broadcast room: "Enough is enough! Don't think of the anchor like you. If you are looking for it, you are looking for me. I have all kinds of big movies and small movies here..."

The audience in the live broadcast room "really eats melons and the masses are unparalleled": "Give some seeds upstairs, one of the farmers wants to plant the land..."

Hu Yanshuo has nothing to do with these crooked paintings, but Chen Lingxi couldn't help but ask curiously, "How about you? How do you usually refresh your mind? Do you also use small movies or something like them?"

This question made Hu Yanshuo embarrassed for a while, you are a goddess-level beauty, why are you curious about this?

"This method is similar to drinking poison to quench thirst, which is not advisable!"

After thinking about it, Hu Yanshuo's compromised answer made Chen Lingxi's eyes light up, and said, "Then how do you usually solve the problem of not being able to raise your mind?"

"Being an adventurer is the most refreshing thing."

Faced with such a large-scale question, Hu Yanshuo thought about it for a while and answered seriously.

Just when Hu Yanshuo was about to move his fingers and force the topic back on track, some viewers in the live broadcast room also began to wonder what mathematical argument Hou Shuge was studying.

The audience in the live broadcast room "smashed walnuts with their mobile phones": "Enough of you, the crooked building is too serious. Am I the only one who is curious about what mathematical arguments the anchor is studying?"

"Schrödinger's Box" from the audience in the live broadcast room: "Same curiosity!"

The audience in the live broadcast room "I opened the safe thief 6": "The anchor tells me what kind of mathematical argument makes you almost let Niu Dashen crawl out to find you, which makes me curious too."

Under the curious questioning of the audience in the live broadcast room, Hou Shuge hesitated for a while before saying slowly: "I have recently been demonstrating Goldbach's conjecture, and I have reached a bottleneck. I don't know how to proceed."

As soon as the words came out, there was a feeling that one stone stirred up a thousand waves.

The audience in the live broadcast room "Preschool Xiaoxin": "Goldbach Conjecture?"

The audience in the live broadcast room "Minke Zhang Wuji": "Boss, don't scare me? Do you prove Goldbach's conjecture?"

The audience in the live broadcast room "splashed to the bone": "The wording upstairs is biased, it is an argument, not a proof, you can't use the host to trick the anchor..."

The audience in the live broadcast room "Xiao Hei is discussing downstairs": "Curious, what is the subject of the argument? Goldbach's conjecture 1+1?"

"Chen Haoran", the audience in the live broadcast room: "Isn't the way of Goldbach's conjecture blocked?"

The audience in the live broadcast room "silently took blood": "Is it blocked? Remove it, block it, and give up the main broadcast!"

The audience in the live broadcast room "thermo flask": "Goldbach's conjecture is dead, burning paper for small things, digging graves for big things..."

Live audience...

Among the audience in the live broadcast room, there were two distinct factions, one was for support, the other was against, and they could say anything, and some people doubted whether this was Hou Shuge's hype.

This point is really too topical.

The conjecture that has plagued the mathematics community for hundreds of years has been dug by countless amateur mathematics people more than once.

Even online authors have not spared the heat.

In a letter to Euler in 1742, Goldbach proposed the following conjecture: Any integer greater than 2 can be written as the sum of three prime numbers. Since the convention of "1 is also a prime number" is no longer used in mathematics today, the modern statement of the original conjecture is that any integer greater than 5 can be written as the sum of three prime numbers. In his reply, Euler also proposed another equivalent version, that is, any even number greater than 2 can be written as the sum of two prime numbers. Common conjecture statements are Euler's version. The proposition "Any sufficiently large even number can be expressed as the sum of a number with no more than a prime factors and another number with no more than b prime factors" is written as "a+b".

A common statement of the conjecture is Euler's version that any even number greater than 2 can be written as the sum of two prime numbers, also known as "Strong Goldbach's Conjecture" or "Goldbach's Conjecture on Even Numbers".

From Goldbach's conjecture about even numbers, it can be deduced that any odd number greater than 7 can be written as the conjecture of the sum of three prime numbers. The latter is called "weak Goldbach conjecture" or "Goldbach conjecture on odd numbers".

If Goldbach's conjecture about even numbers is true, then Goldbach's conjecture about odd numbers will also be true. The weak Goldbach conjecture has not been completely solved, but in 1937 the former Soviet mathematician Vinogradov has proved that a sufficiently large odd prime number can be written as the sum of three prime numbers, also known as "Goldbach-Vinogradov". Mathematicians believe that the weak Goldbach conjecture has been basically solved.

Four ways to study Goldbach's conjecture for even numbers. The four approaches are: almost prime numbers, exceptional sets, the triple prime number theorem for small variables, and the almost Goldbach problem.

An almost prime number is a positive integer with a small number of prime factors.

Now let n be an even number. Although it cannot be proved that n is the sum of two prime numbers, it can be proved that it can be written as the sum of two almost prime numbers, that is, n=a+b, where the number of prime factors of a and b is not too large. many.

For example, the number of prime factors does not exceed 10.

Use "a+b" to represent the following proposition: every large even number n can be represented as a+b, where the number of prime factors of a and b does not exceed a and b, respectively.

Obviously.

Goldbach's conjecture can be written as "1+1".

Progress in this direction has been obtained using the so-called sieve method.

As a result, the "a+b" problem is advanced.

In 1920, Brown of Norway proved "9+9".

In 1924, Germany's Ratmacher proved "7+7".

In 1932, the British Esterman proved "6+6".

In 1937, Lacey of Italy successively proved "5+7", "4+9", "3+15" and "2+366".

In 1938, the Soviet Union's Buchsi Taibo proved "5+5".

In 1940, the Soviet Union's Buchsi Taibo proved "4+4".

In 1948, Reni of Hungary proved "1+c", where c is a large natural number.

In 1956, China's Wang Yuan proved "3+4". "3+3" and "2+3" were later proved.

In 1962, China's Pan Chengdong and Soviet Union's Barbaen proved "1+5", and China's Wang Yuan proved "1+4".

In 1965, the Soviet Union's Buchsi Taibo and small Vinogradov, and Italy's Bombili proved "1+3".

In 1966, China's Chen Jingrun proved "1+2".

Take a fixed large integer x on the number line, and then look forward from x to find those even numbers that make Goldbach's conjecture invalid, that is, exceptional even numbers.

The number of all exceptional even numbers before x is denoted as e.

Many people hope that no matter how large x is, there is only one exception even before x, and that is 2, that is, only 2 makes the conjecture wrong. In this way, Goldbach's conjecture is equivalent to e is always equal to 1. Of course, e=1 could not be proved until 2013;

but.

It can be shown that e is much smaller than x.

The even numbers in front of x are probably x/2; if the ratio of e to x tends to zero as x tends to infinity, it means that the density of these exceptional even numbers is zero, that is, Goldbach's conjecture for almost all even numbers established.

That's the idea of ​​exception sets.

…

Vinogradov's triple prime number theorem was published in 1937. In the second year, four proofs appeared at the same time, including Mr. Hua Luogeng's famous theorem, in the way of exception set.

If Goldbach's conjecture for even numbers is correct, then so is the conjecture for odd numbers. We can turn this question around. It is known that the odd number n can be expressed as the sum of three prime numbers. If it can be proved that one of the three prime numbers is very small, for example, the first prime number can always take 3, then we have also proved the Goldbach conjecture of even numbers. .

This thought prompted Mr. Pan Chengdong to study the three prime number theorem with a small prime variable in 1959, when he was 25 years old.

This small prime variable does not exceed n to the θ power.

Our goal is to prove that θ can take 0, that is, this small prime variable is bounded, thereby deriving Goldbach's conjecture for even numbers. Mr. Pan Chengdong first proved that θ can be taken as 1/4.

For a long period of time, there was no progress in this area until Professor Zhan Tao advanced Mr. Pan's theorem to 7/120 in 1995. This number is already relatively small, but still greater than 0.

…

In 1953, Linnick published a 70-page paper.

In the paper, he pioneered the study of almost Goldbach's problem, proving that...there exists a fixed non-negative integer k such that any large even number can be written as the sum of two prime numbers and k powers of 2.

This theorem seems to smear Goldbach's conjecture, but it is actually very profound.

This theorem draws attention to the fact that integers that can be written as the sum of k powers of 2 form a very sparse set;

In fact, for any given x, the number of such integers in front of x will not exceed the k power of logx.

Therefore, when Linnick's theorem appeared, many people passed it and learned that although Goldbach's conjecture could not be proved, everyone could find a very sparse subset in the set of integers, and each time from this sparse subset Take an element and paste it into the expression of these two prime numbers, and the expression will hold.

Here k is used to measure how close the almost Goldbach problem is to the Goldbach conjecture.

A smaller value of k indicates a better approximation.

It is obvious that if k is equal to 0, almost the power of 2 in Goldbach's problem will no longer appear. Therefore, Linnick's theorem is Goldbach's conjecture.

Because Linnick's 1953 paper did not specify an allowable value of k.

Therefore, in the following decades, people still do not know how much k can make Linnick's theorem hold.

but.

In Linnick's well-documented argument, this k should be large.

In 1999, after the cooperation of Professor Liao Mingzhe and others, the allowable value of k was determined for the first time to be 54000.

The first allowable value of 54,000 allowable values ​​was continuously improved step by step.

Two of the results must be mentioned, namely, Li Hongze and Wang Tianze independently obtained k=2000. The best result k = 13 was achieved by the British mathematician Heath-Brown and the German mathematician Puchta, which is a big breakthrough.

…

That's why the audience in the live broadcast room asked if Hou Shuge was arguing that Goldbach guessed 1+1.

The essence of proving the establishment of '1+1' is to prove that "starting from 2, continuous 2, 4, 6,, 1... infinitely large even numbers can be represented by the sum of two prime numbers". It can also be said that "the sum of two prime numbers can form an arithmetic sequence with a tolerance of 2", which is easier to understand and understand the requirements of the "Goldbach Conjecture", or it can be expressed by "1+1".

In 1966, mathematician Chen Jingrun proved that "1+2" ​​holds, that is, "any sufficiently large even number can be expressed as the sum of two prime numbers, or the sum of a prime number and a semi-prime number".

The expression is "n=p\'+p"n=p1+p2p3.

This expression proves that '1+2' holds, which refers to the range of even numbers greater than 10.

The scope of application is "sufficiently large", which refers to 10 to the power of 500,000, which is very large and has exceeded the number of all atoms in the universe. However, if it can be proved in the "sufficiently large" range, there will be great persuasiveness, and there is no need to use infinity. It is something that nature does not have, and "sufficiently large" is enough to explain the problem.

Then.

There are also Western scientists who believe that the establishment of '1+2' cannot be proved by any proof that does not use the range of 'infinity'.

In the range of 10 to the 500,000th power, most people think that the difficulty will be much easier if it can be proved that the "Goldbach Conjecture" does not hold. Therefore, it is necessary to abolish the concept of 'infinite, infinitesimal', because the study of 'Goldbach's conjecture', if there is a solid argument, "if it can prove that 'Goldbach's conjecture' does not hold within a huge range, it is more difficult than 'to prove true. 'The difficulty is much less.

However.

Some viewers in the live room believed that Goldbach's conjecture had been blocked.

That's because it can deny the "Goldbach Conjecture" using logic proof. This kind of logic proof that has been verified by experts has been recognized by many people!

The published thought process is simple and easy to understand, and logical thinking is one-to-one

The scope of application is also the largest 'interval' of 10 to the power of 500,000, and the smallest is the beginning of the prime number '3/5/7/11/13/17... to the power of 10 to the power of 500,000 as proof scope. In fact, even if we can find that a certain segment of the '2 arithmetic sequence' is missing a small segment, or there are one or more counterexamples, the 'Goldbach's conjecture' cannot be established.

From '1+9'/'1+8'/'1+7'... to Chen Jingrun's proof result "1+2", mathematicians in history have jointly proved that "in' From 1+9' to 1+2' 'joint and relay to prove the conclusion', it is obtained that any large even number expressed as a prime number can be "a large even number, which can only be expressed as the sum of a prime number and a composite number. "form.

The connotation is the same - any even number can only be expressed as "a prime number + a composite number". The results of their proofs do not violate logic and do not produce contradictory conclusions.

therefore.

Even if it is the expression of the product of w prime numbers after it, because all the latter terms with the expression of 'x' must be a composite number. It can be judged that the proof calibers of scientists are all the same, and the '+ sign' cannot be followed by a 'prime number'.

After the '1+2' proved the result, the math enthusiasts who have worked hard and have worked hard, the goal is to continue to prove that '1+1' is established on the basis of previous research and 'reach the peak'.

but.

Many people make inferences with logical thinking, which is completely impossible!

Because to prove '1+1', we essentially continue to prove that the '2' (non-prime number) after '1+2' is a 'prime number'. This will definitely be the logic behind. . . .

so.

It is concluded that '1+2' is the ultimate conclusion, and 'Goldbach guess' does not hold.

…

Glancing at Chen Lingxi who was listening quietly beside her...

finally.

At the end of Hu Yanshuo's last words.

Just saw Chen Lingxi's eyes, directly shining with brilliance, this is the light of worship.

Such a look of admiration.

Hu Yanshuo was rarely seen in Chen Lingxi's eyes!

…

Even if he is Wu Neng invincible in the urban forest, across hundreds of millions of battlefields, killing the eight wastes.

The writing can also be unparalleled in the world, and the literary talent is unparalleled in the world, covering all the arrogance and dissatisfaction in the world.

Heaven does not give birth to me, Hu Wudi, eternal civility and military indifference.

Hu Wudi, the **** of war who walks in the world.

With such awesome strength, Chen Lingxi couldn't show such a look of admiration.

The knowledge points that merely spent 6 million yuan in the Krypton Gold Mall, were actually admired by Chen Lingxi, making Hu Wudi, a martial **** who walks in the world, couldn't help but be puzzled and speechless.

All right!

Most people probably know about the world-famous Goldbach conjecture as "1+2" ​​and "1+1". Unless mathematics enthusiasts, few people will understand this kind of academic problem.

Hu Yanshuo didn't want to write down these things in order to pretend before.

so.

He actually didn't know that either.

The reason why she knew it was because Chen Lingxi didn't know.

Chen Lingxi didn't know it anymore, so she asked Hu Yanshuo who was watching the live video with great interest. Then, Hu Yanshuo didn't understand this at all, and she felt ashamed, what should I do?

If you change the time and place, Hu Yanshuo will endure it.

But.

this time.

this location.

A man and a woman are lying on the bed, the woman asks the man, do you know what? Do you understand?

Curious and expectant eyes.

It's like asking directly, are you okay?

Even this question is not related to actual combat.

but.

As a man lying in bed, how many are willing to admit that they can't?

In such a situation, generally those with insufficient emotional intelligence will choose the last resort and admit their counsel in a disheartened manner.

Zhongce needs a little emotional intelligence, and the most important thing is physical strength. Just go straight to the end, change the subject and tell her that you are good, very good, the Chinese people are very good...

The best strategy is Hu Yanshuo's coercive mode, and those who are poked professionally are more fortunate.

Although Hu Yanshuo has not been poked into a major, it does not prevent him from cheating. Therefore, between the right and the wrong, Hu Yanshuo feels that he will definitely not choose the next strategy, so he is very stable in the middle strategy. After all, he is in the city. Hu Wudi, who is invincible in the world, but in the face of a situation where there is a better strategy...

Well, Hu Yanshuo felt that the knowledge points were not enough, and krypton gold came to collect. If there is no complete despair, krypton gold mall should be able to rescue it.

therefore.

Hu Yanshuo directly opened the Krypton Gold Mall and searched for math skills...

Then.

When he found a series of mathematical skills, and when the huge number could make him despair, Hu Yanshuo had an idea. Hu Yanshuo searched for the originator, the world-famous Goldbach conjecture.

The search results surprised Hu Yanshuo for a while.

Surprisingly, in the Krypton Gold Mall, Goldbach's conjecture proved knowledge points!

And ~www.wuxiaspot.com~ is amazingly huge.

Brushing the question bank is not so outrageous.

The joy is of course the capital that has the pretense.

There is absolutely no need to face the "you can't" look of the woman on the bed. Although Hu Yanshuo has never encountered such a situation, it does not prevent him from rejecting this situation, and he does not want to encounter such a look at all!

at the same time.

Hu Yanshuo is very sure that the game upgrade is still beneficial.

When it was changed to the previous level 2, it was absolutely impossible for these things to exist in the krypton gold mall.

took a look.

Hu Yanshuo found that these search results also included the proof of the world-famous Goldbach conjecture 1+1, in which the selling price of the entire series of contents was 6 million yuan.

Shocked.

Under Chen Lingxi's eyes, Hu Yanshuo didn't have time to think about it, he just spent millions of dollars to get the knowledge points of the world-famous Goldbach conjecture 1+1.

Krypton paid 6 million yuan, in addition to adding 600 experience points to Hu Yanshuo.

He was also able to imprint the proof formula of the world-famous Goldbach conjecture into his mind.

Although his real academic level is not that high except for the knowledge points of the world-famous Goldbach conjecture proof formula, Hu Yanshuo pretended to pretend to be the world-famous Goldbach conjecture in front of Chen Lingxi. The academic problems in mathematics are simply blind, and you can't get through without krypton gold...

Now that you have acquired these knowledge points.

Hu Yanshuo naturally wanted to explain Chen Lingxi seriously, but he didn't expect to get Chen Lingxi's adoring eyes.

This look made Hu Yanshuo a little interested.

I thought to myself, do I want to practice and ride the clouds? Well, the facilities in this hotel are a bit rudimentary!
