Chapter 293

Is this...

is this serious?

Everyone in the room was deeply skeptical.

No kidding, although it's just a game of guessing passwords, most people regard it as a challenge in probability.

Of course,

people adopt different methods. Some people use the probability limit theory, while others use the probability distribution, that is, the probability property of random variables. Some people use Markov process to study the spatial problems of discrete event dynamic system state.

However,

the probability of all four digit passwords is equal, and the probability is 5000.5 times.

After that, everyone began to expand, because this is a four digit password set artificially. From the perspective of human thinking, the probability of four digit password appearing is no longer equal, and the number of attempts will be greatly shortened.

Since then,

the small password cabinet has become a carnival of many mathematical talents and teachers, who are full of youth in probability theory.

As a result...

a person came out and stopped the carnival of probability theory.

"..."

"..."

"..."

is this a random event?

Otherwise, how could it be?!

In other words,

who is he?

At the same time,

the most angry one was Yang Xiaoman, who felt that she had been cheated by the routine.

Yang Xiaoman: (~ ~)

how angry!

I was cheated!

Let you pay a painful price at night!

"Ah?"

"You... You seem to be Xu mang?" One of the students on the scene recognized Xu mang. He was a member of the delegation from Zhejiang Province. He once played against Xu Mang in the Zhejiang Olympic Games, and then was defeated... Since then, Xu Mang's face has been remembered.

"..."

"I'm not!" Xu mang quickly shook his head: "my name is Xu Yang!"

"You..."

"aren't you Xu mang?" "Why did you have a face like Xu mang who didn't deserve to be beaten?" the student asked

I...

you're too much!

When Xu mang heard the student's words, he almost had no bleeding. He was young and had such a serious cataract. He clearly had a beautiful face in his life, but in his eyes, it was a face to be beaten. I'm afraid it's not the late stage of cataract?

"You'd better go to the eye department." Xu mang said solemnly, "I'm afraid you'll be blind tomorrow."

The student exclaimed excitedly, "you are Xu mang! There is no one in the world who is more mean than you, just like you

Xu mang?

Is he Xu mang?

Who is Xu mang?

Most people don't know Xu mang. After all, Xu mang has made some achievements in materials science and physics, but he has never made any achievements in the field of mathematics. In addition, his influence is limited to magic capital, capital city and Zhejiang Province.

The capital city is special because the experimental sites of materials science database are in Beijing and magic capital. The universities in Beijing have heard of Xu mang more or less.

Other... Sorry, I don't know!

"Classmate, how do you work out the password at one time?"

"What theory was used?"

"Is it a coincidence?"

In an instant,

Xu mang was surrounded by a group of people. At this time, he was a little confused.

"Er..."

"in fact, I did not use mathematical thinking to consider the password probability problem." Xu said cautiously: "I use the behavioral logic in psychology to think about the possibility of password. It has nothing to do with mathematics."

"Sorry..."

"I cheated." "In the face of such a situation, no matter how it is calculated objectively, the final answer is the same, unless subjective consciousness is added," Xu said awkwardly

"But I gave up objectivity and chose subjectivity." "From people's logical behavior to consider the problem, plus their own little inference, finally come to a correct password," Xu said

At this point,

a team leader asked, "I have also considered subjectivity, but I need a reference condition. This password cabinet only has a password, and other information is unknown. How can I find a valuable subjective consciousness?"

This is all people's doubts, lack of a reference, and thus lack of a condition.

Xu mang laughed and said in silence, "you may not have found the wear on the password key. I just refer to this wear condition and infer."

Wear condition?Not to mention,

looking closely, I found that it was a little dim.

However,

if you don't look closely, you can't find out. How did he see it?

"No

"You haven't been near the password cabinet before. How did you find out this problem?" One student said, "I stand so close that I can't find it."

"Because you are Xueba!"

"And I used to be a loser!" Xu mang is suddenly filled with a long time lost sense of pride.

Learning dregs,

have a special inborn ability. Their eyesight is very good. With a gap of one meter, they can make a perfect copy of the answers on the examination papers of the students nearby.

Indeed,

you can't find it if you don't look carefully. However, with nearly ten years of experience, Xu mang can accurately distinguish the color difference of the paint on the buttons.

It has to be said,

sometimes the learning experience is quite useful.

It's just that...

the people present are confused about Xu's answer. Can this learning slag be linked to his eyesight?

After that,

this group of extremely boring mathematicians, including Xu Mang, had a heated debate on whether mathematics can achieve the perfect axiom deduction and whether it can ensure that there is no internal contradiction.

At present, there are some limitations of axiomatization in mathematics. Some procedures of mathematical proof cannot be determined to be consistent with formal axioms.

Taking the password cabinet as an example,

it is impossible to get a perfect answer by pure mathematics. However, a perfect solution can be obtained by relying on people's subjective thinking, which can not be expressed in mathematics.

Therefore,

this group of boring mathematicians formed two sides. On the one hand, they thought that mathematics could not achieve perfect axiom deduction, and some problems must have internal contradictions. On the other hand, the other side believed that the future mathematics would certainly achieve the perfect axiom deduction, and there was no contradiction.

The two sides began to compete with each other, even with the possibility of doing something.

Finally, Xu mang stood up.

In his idea, human wisdom cannot be replaced by complete formulas. For example, he used behavioral psychology to crack the process of password cabinet. There is no formula to express.

Therefore,

for formal systems, "provable" can be realized mechanically, but "truth" needs further consideration.

A provable proposition must be true, but a true proposition is not necessarily provable.

It's a pity that Xu Mang's remarks didn't have any effect, on the contrary, it made the contradiction between the two sides more diffuse and almost didn't really fight...

soon,

the crowd dispersed in displeasure, and Xu Mang's troubles just started.

"Hey, hey, hey!"

"I'll take care of my money in the future." Xu mang looked at Xiaoman with a look on his face and said triumphantly, "you have to learn how to wash, cook and mop the floor. Do you know? Or you will be deducted from the money you paid for cosmetics! "

"Hum!"

"Again, who is in charge of the money at home?" Yang Xiaoman disdains to say: "what did I promise you?"

Xu Mang: ∑ (°Δ°||︴︴︴︴︴︴︴︴|||︴︴︴︴︴︴︴!

Xiaoman is going to turn his face and refuse to recognize people!

What to do?

"I..."

"I have a recording." Xu mang opened the mobile phone recording, and then appeared the fragment of Xiaoman boasting about Haikou.

However,

in front of the iron evidence, Yang Xiaoman was not moved and said calmly: "this is a fake!"

Xu mang shrinks his head. He knows that Xiaoman is going to default, but there is no way. Who can't beat her?

think about his mother,

think about his lucky money in the past. If you want to save it for you, ask your mother to take it.

The next day I went to get the money, but I was asked, "do you have lucky money?"?

Alas...

women!

"What about my two nights a week?" "Does it count?" Xu asked

"What do you think?" Yang Xiaoman said haughtily.

"..."

"Xiaoman?" Xu mang said painfully, "is your father living in the heat and water all day?"

...

finally, when Xiaoman came on the stage,

Xu mang was still in a state of deep resentment. He thought he had set a routine for Xiaoman, but he was finally given the routine by Xiaoman.

It is said that love makes women stupid. It was true in the past, but recently, Xiao man has become more and more shrewd, and has a feeling of wanting to be a queen...

Xu sighed, silently took out his mobile phone, opened the furnace stone legend, and then angry krypton 10000 yuan.

Open the card bag!

Only the Golden Legend can save one's fragile soul."Ordinary!"

"Ordinary!"

"Rare!"

Open open, in front of the card bag almost open, Xu Mang's heart is also gradually fragile.

"Wow! Gold... Ordinary. "

Xu Mang: wdnmd

exit,

uninstall.

Xu mang said goodbye to the furnace stone circle.

Taking advantage of this boring time, Xu mang began to think about upgrading the materials science database. In fact, the technology is not a problem, the problem is that the money is not enough... Vice director Zhou casually makes a request, which requires a lot of capital investment.

According to the principle, the money will be distributed by the scientific research department, but just distributed a sum of money, the result has not been more than a month, the money is not enough... Seems to be a bit excessive.

How about...

raise the price?

Xu mang considers that software price increases to collect R & D expenses. First of all, from the perspective of morality and law, price increase is a matter of course. The software itself is used to serve customers. Now, in order to improve the quality of service, can the price rise to violate the law?

Secondly,

upgrading the database was put forward by the deputy director of the materials department of Qingda, and it was not for no reason that he wanted to upgrade the database. This was a passive upgrade and also a forced upgrade, so the money could not be paid by himself.

Based on the above two points, the money is paid by Qingda!

But who will pay for Qingda's money? Let them solve it by themselves.

Thinking of this,

Xu mang called deputy director Zhou, and the two had saved their numbers before.

"Hello?"

"Director Zhou!" Xu mang said solemnly: "I suddenly think of one thing, you don't want me to upgrade the database, I think... The technical aspect is not a problem, but who will pay for it?"
