We Live In Nanjing

  Chapter 59 Three Laws in Exploration and Summary

  [Excerpts from Interview Records, Three Laws in Exploration and Summary:

  The author met Zhao Bowen at the end of 2020. This Nanjing University physics professor has a very tight schedule and is very busy at work. The date agreed on WeChat was postponed twice in a row before he took time to accept the author’s interview.

We found a cafe near Zhongshan Road. The agreed time was two o’clock in the afternoon. The author arrived at 1:40. I turned on the computer and mobile phone on the small table and ordered a cup of tea. When it was two o’clock, Zhao Bowen arrived on time. . The winter in Nanjing is still very cold, and there is a drizzle outside the glass windows. A tall and thin man opened the door of the cafe and walked in, a long gray trench coat, black trousers, tortoiseshell glasses, and a folding umbrella in his hand. He raised his head and glanced around, his eyes fell on me.

  I waved gently, and he waved too.

   Purpose and carrying information, are these two physical concepts?

I asked.

No.

  The man sitting opposite waved his hand and smiled.

  These are two verbal concepts.

  Kouhu? I was a little surprised.

   Strictly speaking, it is just verbal humiliation.

  Zhao Bowen nodded.

We did not have time to do any further experimental verification-although it did show a guiding role in practice, it was quite useful, but usefulness and correctness are two different things. Teacher Tianrui, you know that our situation at the time is a dead end. Living horse doctors, everyone's eyes are dark. You only know that the sky will fall in a short time, and you don't know anything else. This is the most terrifying.

  Zhao Bowen scratched his forehead.

If you want to study in depth, this may be a major cut that can subvert the modern physics system. However, the situation at the time was that everything was to reverse the future and eliminate disasters as the top priority, and other things were put aside. After all, if humans are all Is destroyed, what is the role of studying physics? right? After the whole incident was over, we had enough time and manpower to study this issue... but there was no chance.

  Professor took a sip as he picked up the hot coffee on the table.

  Well, this coffee tastes okay.

  He raised his head and nodded at me.

  The girl is a good boy.

  He said suddenly.

  The author was taken aback for a moment, and then nodded, yes, she is a good boy.

  Zhao Bowen knew he was aphasia, smiled a little embarrassingly, and immersed himself in a cup of coffee.

  Professor, you just mentioned that the two concepts of purpose and carrying information have indeed played a guiding role in practice. What is purpose? What is carrying information?

I say.

Yes, they did play a role. Let us have a general direction and know which direction to explore. Purpose is actually a negative BUFF. It will make the world obstruct you. For example, I believe Tianrui Teacher, you must have this kind of experience in your daily life. If you can't find something, the harder you try to find it, the more you won't find it. But if you don't deliberately find it, it will pop out on its own.

  Author: This is just because you are nearsighted, right?

  Zhao Bowen: Are you polite?

  ·

  ·

  ·

  Zhao Bowen went on to say:

  The result of this negative BUFF in the slow delivery of time is that the more purposeful you are, the greater the obstruction you will encounter, and the greater the probability of delivery failure.

  But purpose is our human subjective thinking. It is just the intention in our brain. For example, I want to go to a certain place and I want to give this cup of coffee to someone. Can this kind of thinking affect the objective physical world?

  I have some doubts.

   is a bit mysterious, right? Just like the Copenhagen interpretation of quantum mechanics, Schrödinger’s cat, the observer can determine the life and death of the cat. If you don’t look at it, it is the superposition state of the wave function. When you look at it, it collapses into a certain state. It seems that the observer's own thinking is affecting the objective world.

  Zhao Bowen smiled.

But here, purpose is not an ideal concept. It has a real impact. I still cite the old example, Mr. Tianrui. I just threw a stone outside the door and hid it in the flowerbed by the road. Let someone pick it up here, what is the difference between these two behaviors?

  The first behavior has no purpose, and the second behavior has a clear purpose.

  I answer.

  Zhao Bowen nodded:

What is the fundamental difference between   ?

  I am choked.

  Zhao Bowen took another sip of coffee and revealed the answer:

   is very simple, the difference is whether you carry information, teacher Tian Rui... have you heard of Shannon?

  ·

  ·

  ·

I never thought that I would discuss Shannon’s information theory with a professor of physics in a coffee shop. The gray-haired, long-faced old man is undoubtedly one of the most important scientists in human history, the theoretical founder of the information age, and a man. Having fixed the wonderful work of the entire theoretical system, the contemporary advanced Internet and information industries-no matter what 2G, 3G, 456G, have to kneel down and call him the ancestor.

In Zhao Bowen’s view, the fundamental feature of purpose is to carry information. You throw the stone away at will. This behavior does not carry any information, but if you bury the stone in the flower bed and wait for someone to fetch it, then carry it. A lot of information.

  One of the foundations of Shannon’s information theory is to expose that the fundamental feature of information is to eliminate uncertainty. The more uncertainty is eliminated, the greater the amount of information.

  It will rain tomorrow.

  This sentence contains information.

  It will rain tomorrow.

  This sentence contains more information.

  Next, Zhao Bowen turned around and talked about the Maxwell Demon with the author.

  Tianrui, have you heard of Maxwell’s demon?

  Have heard it.

  I nodded.

  Maxwell’s demon, a famous beast in the history of physics, is as famous as Schrodinger’s cat.

  Maxwell monster, the little monster that controls the valve, it can detect the internal energy of a single particle, the speed of the particle, right? The fast-flying particles are let go, and the slow-flying particles are stopped. Zhao Bowen said, let’s assume that there will be another monster, a big monster, and call it——

  Professor glanced at me.

——Just call it Tianrui, said rune demon, Tianrui demon, this monster is very, very huge, so huge that it can cover the entire world, it can also control a valve, but this valve distinguishes not the speed of movement, not the implied Internal energy is the amount of information. Targets that carry huge amounts of information will be stopped by it. Objects that do not carry information can be unimpeded.

  I suddenly understood what Zhao Bowen meant.

  Time slow delivery failed because of this? Because the purpose is too strong and the amount of information is too large?

  Zhao Bowen nodded.

This is why burying the time capsule needs to follow the double-blind principle. This is actually weakening the purpose. Strictly speaking, the more times the time capsule is burying, the more chaotic the steps, the weaker the purpose. From the perspective of this world, the closer its behavior is to random changes, the more uncertainty it carries, the less information it carries, and the closer it is to me throwing stones outside.

  This is deceiving the world.

I say.

Yes.

  Zhao Bowen nodded.

  This is deceiving the world.

  That... Then, what is the specific existence of this sky demon?

I asked.

   is a disaster.

  Zhao Bowen replied.

It was the black moon coming and the earth-shaking disaster. At that time, we called this mechanism the filter mechanism. The world is like a big filter, filtering all the things we send over. As a monster, it is very naughty and hateful. You deliberately make trouble for someone, if you give him a screwed Rubik's Cube, it must be screwed up for you, but if you give it a Rubik's Cube that is already messy, it won't bother to move.

  Does it take the initiative to do so?

I asked.

Of course not. Whether it is Tianrui talking about rune monsters or big filters, they are just descriptions of this mechanism and phenomenon, to make an analogy for people to understand. In essence, the reason for this result is the human civilization after the disaster strikes. The huge increase in entropy and the dissipation and distortion of information.

  Zhao Bowen replied.

  The more information the target carries, the more distorted it will be, and it will be lost in the end.

I say.

  Zhao Bowen nodded: But the goal that doesn't carry much information at the beginning is not affected by anything.

At this time, the author finally understands the transport mechanism of time slow delivery. Through double-blind or even multi-blind burying methods, the purpose of the time capsule is reduced as much as possible, and its randomness and uncertainty are increased. The greater the uncertainty, The amount of information is smaller. At this moment, the information carried by the time capsule is diffused to the entire universe, so that it can pass through the big filter-this is the so-called deception of the world, you must deceive yourself.

But it’s not enough to deceive yourself. A target with information scattered throughout the universe that no one can find is like throwing a capsule into Xuanwu Lake at will and no one can get it out. The next part is the second half of the plan. , Let that girl find it.

  Zhao Bowen said that theoretically this capsule cannot be found, and the amount of information it carries is too small, but it happens that they have a savior outside of theory.

  Icom725.

  We put ourselves to death and live afterwards, we put ourselves to death first, and the life-saving straw that pulled us out is the two-five radio station.

  Zhao Bowen said leisurely.

This is very strange. This kind of plan is impossible to succeed if there is no two or five radio stations. It is the last key to complete the closed loop. If the radio station transmits the past, the information dispersed in the entire universe can be instantly collapsed to a certain point. Just as the wave function spreading to the entire universe collapses into a specific amount, only with the presence of a radio station can the girl restore the originally chaotic Rubik's Cube. At that moment, the originally huge entropy will suddenly drop!

  This is the third law of slow time passing.

  Zhao Bowen said softly.

   is also a summary and coverage of the first two laws.

  ——Everything must be done to weaken the purpose and reduce the amount of information carried. ]

  The white poplar was silent for a long time.

   "Understood?" Zhao Bowen finished smoking the cigarette in his hand and rubbed the cigarette **** on the floor.

   “According to this, the method of transporting materials is not only a time capsule.” Bai Yang said.

   "Of course there is more." Zhao Bowen nodded, "In theory, as long as the three laws are followed, the methods within the framework of these three laws will be feasible."

   "Then can you give her an air conditioner?"

  Zhao Bowen was taken aback, "What?"
