Chapter 292 From Logic to Mathematics (1/3)(1/2)
this
Is this serious?
Everyone present was deeply suspicious of this.
No joke, although this is just a password guessing game, most people regard it as a probability challenge.
certainly,
The methods adopted by everyone are also different. Some people use probability limit theory, while some people use probability distribution, that is, the probabilistic nature of random variables. Some people go too far and use Markov processes to study the state of discrete event dynamic systems.
space problem.
but,
The probability of occurrence of all four-digit passwords is equal to 5,000.5 times.
After that, everyone began to expand, because this was an artificially set four-digit password. From the perspective of human thinking, the probability of a four-digit password appearing is no longer impossible, and the number of attempts will be greatly shortened.
Thereafter,
The small password cabinet has become a carnival for many mathematical geniuses and teachers, who spend their youth in probability theory.
result
Someone comes out,
He came up and put an end to this carnival of probability theory.

Is this a random event?
Otherwise how is it possible?!
In other words,
who is he?
at the same time,
The most angry person was Yang Xiaoman. She felt that she had been tricked and deceived by this guy.
Yang Xiaoman:(# ̄~ ̄#)
So angry!
I was actually deceived!
You will pay a heavy price tonight!
"well?"
"You seem to be Xu Mang, right?" One of the students present recognized Xu Mang. He is a member of the representative team from Zhejiang Province. He once played against Xu Mang in the Zhejiang Province Mathematical Olympiad Competition and then lost completely.
I remembered Xu Mang's face.
""
"I'm not!" Xu Mang shook his head hastily: "My name is Xu Yang!"
"you"
"Aren't you Xu Mang?" the student asked with confusion, "Why do you have a face that deserves a beating like Xu Mang's?"
I
You guys have gone too far!
When Xu Mang heard this student's words, he almost lost his breath. This man was so young and had such serious cataracts. He obviously had a beautiful face, but in his eyes, he deserved a beating.
My face, I’m afraid it’s not an advanced stage of cataract, right?
"You'd better go see an ophthalmologist." Xu Mang said seriously, "I'm afraid you'll be blind tomorrow!"
The words fell,
The student shouted excitedly: "You are Xu Mang! With this bitch* energy in you, there is no person in the world meaner than you!"
Xu Mang?
Is he Xu Mang?
By the way, who is Xu Mang?
Most people don't know Xu Mang. After all, Xu Mang has only achieved some achievements in materials science and physics, but has never achieved anything in the field of mathematics. In addition, his influence is limited to the Magic City.
Beijing and Zhejiang Province.
And the capital city is quite special, because the testing sites for the materials science database are chosen in the capital city and the Magic City, and universities in the capital city have heard of Xu Mang to some extent.
Sorry for the others, I really don’t know them!
"Classmate, how did you calculate the password in one go?"
"What theory was used?"
"Is it a coincidence?"
moment,
Xu Mang was surrounded by a group of people, and he was a little confused at this time.
"Well"
"Actually, I didn't use mathematical thinking to think about the probability of passwords." Xu Mang said carefully: "I used behavioral logic in psychology to think about the possibility of passwords. It has nothing to do with mathematics."
"Excuse me"
"I cheated." Xu Mang said awkwardly: "In the face of such a possible situation, objectively no matter how you calculate it, the final answer will be the same, unless you add subjective consciousness."
"And I gave up objectivity and chose subjectivity." Xu Mang said: "Think about the problem based on people's logical behavior, add a little bit of my own inference, and finally come up with a correct password."
at this time,
A teacher leading the team asked: "I have also considered subjectivity, but I need a reference condition, and this password cabinet only has the password and no other information. How can I find a valuable subjective consciousness?"
This is everyone's doubt. There is a lack of reference and therefore a condition.
Xu Mang smiled and said silently: "You may not have noticed the wear and tear on the password keys. I just made an inference based on this wear and tear."
Wear and tear?
Not to mention,
If you look closely, you can see that it's a bit dim.
but,
You couldn't see it unless you looked closer. How did he see it?
"That's not right!"
"You didn't get close to the password cabinet before. How did you discover this problem?" A student said: "I couldn't even notice it when I was standing so close."
"Because you are a top student!"
"And I used to be a bad student!" Xu Mang suddenly felt a sense of pride that he had not felt for a long time.
slacker student,
Possessing an innate special ability, their eyesight is very good. From a gap of one meter, the poor students can perfectly copy the answers on the test papers of nearby classmates with just a glance.
indeed,
You can't find it without looking carefully, but Xu Mang relied on nearly ten years of experience to accurately identify the color difference problem of the paint on the keys.
I have to say,
Sometimes learning from bad experience is quite useful.
only
People present were a little confused by Xu Mang's answer. Can this scumbag be linked to his eyesight?
After this,
This group of extremely bored mathematicians, including Xu Mang, launched a heated debate on a series of issues regarding whether mathematics can achieve perfect axiomatic deduction and whether it can guarantee that there are no internal contradictions.
At present, mathematics has axiomatic limitations, and some mathematical proof procedures cannot be determined to be consistent with the procedures of formal axioms.
As far as password lockers are concerned,
It is impossible to get a perfect answer through pure mathematics, but a perfect solution can be obtained by relying on human subjective thinking, but this solution cannot be expressed in mathematics.
therefore,
This group of boring mathematicians formed two sides. One side believes that mathematics cannot achieve perfect axiom deduction, and some problems must have internal contradictions, while the other side believes that mathematics in the future will definitely be able to achieve perfect axiomatic deduction, and there will be no contradictions.
The two sides began to compete with each other, and there was even the possibility of taking action.
To be continued...
