"Do you know Schrödinger's cat?" Hatsune Niang did not directly answer Gu Mojie's initial question, but asked rhetorically.

Fortunately, Gu Mojie also has a bit of common sense, and there is certainly no obstacle to this kind of generalization.

"You know, it's nothing more than a metaphor - there's a cat in the box, and a heavy element that has the potential to decay and release radiation. Anyway, according to quantum theory, decay is a random event that may or may not occur, and there is no law to follow. And only when people open the box to observe whether the cat is dead, the result is determined by people - Schrödinger further abstracted this model, setting the 'observation' as an element that 'determines' the outcome, that is, if the cat dies, it is also the action of being opened by the person who opens the box to 'see' the death, and if the person does not look at it, then the cat's life and death can not be qualitated, and it can continue to exist in a quantum superposition state - it is possible to live or die.

Of course, this statement is completely inappropriate for our understanding of the macrocosm: what we have been taught since childhood is that the macrocosm is objective and certain, and that observation does not affect the results. The 150-point paper scored 130 points, and it was decided the moment I handed in the paper, and it will not change because I checked the score or not. ”

"That's a good point, it seems that you have a great talent for physics, and you also have an outstanding ability to think figuratively."

Hatsune Niang praised Gu Mojie, but it immediately attracted another exclamation from Gu Mojie.

"Wait! Wrong! Gu Mojie seemed to be reminded, and asked in surprise: "Why did I forget the next ten years of my life, but I can remember 'Schrödinger's cat'?" I'm pretty sure I didn't read it in high school, and I read it in college out of my personal interest...... But I don't remember the title either. ”

"It's good that you're aware of this, and I have some belief in it—that's what you're qualified to invent me after more than forty years, aren't you—to be still, to think about it, to sum it up, and to see what you've remembered and what you've forgotten."

Hatsune Niang's voice,Finally, from the beginning of the magic frequency of age, I can't hear the magic frequency.,Gradually change to the girl's temptation timbre.,It seems to be full of expectations.。 It's hard to believe that a cold machine can also have emotions, or has artificial intelligence in the future developed to this extent?

Gu Mojie pondered for a long time under the temptation of Hatsune Niang, reviewed the things in his brain, and then said in a hoarse voice:

"I've summed it up. What I can still remember in my mind is nothing more than some science and engineering courses I studied in college, foreign language knowledge in English and Japanese, classical classics I have read, various literacy books in arts and sciences, and so on. But even if I confirm that I have seen the current political events in the next ten years, the rise and fall of the stock market, the new online novels, the blockbuster movies, and the results of the World Cup and Olympic games, even if I confirm that I have seen them, I don't remember them at all. Even his own life experience has become very vague. ”

Hatsune Musume seemed to let out a sigh of even more expectation, and said, "You are very clever and have a good induction—so that the knowledge that 'does not change by it, whether you know it or not', can be completely retained at the moment when you quantize the countercurrent." And the part that you may change will suffer from the washing effect of Yan zhòng when you quantize the countercurrent. This is a fundamental rule of quantum number jù when it completes the reverse flow of the timeline - and the only supreme rule that must be stored locally in Hatsune-Musume-1. I don't need to connect to the cloud database to answer this criterion.

The laws of physics, the laws of mathematics, the basic ideas of writing the C language, the vocabulary and grammar of English and Japanese. Even if you are reborn from 2012 to 2002, you can't change these things, what the laws of physics were in 2002, and what happened in 2012. However, the classic writing cases of C language programs that have appeared in the past ten years, the political events of various countries, and your personal experience are all things that can be changed after you are reborn, so you can't keep them, and once you touch that part of the memory, they will fade quickly, and of course there may be some unclean fragments left. ”

Gu Mojie felt that he was almost on the verge of the limit of brain-burning, and it took a long time to digest this statement. However, the frustration does not dissipate with the success of understanding, but rather becomes more frustrating.

"Yes, that's right, it's logical—but can you tell me why this is the case? Just to make it a little difficult for my rebirth, so that I can't use my prophetic prescience to open my golden thighs like other time-travelers? ”

"Do you know the 'laser pseudo-double grating penetration test'?"

"I don't know, I've never heard of it."

"That's right, then, this real yàn should have happened after 2012, so you haven't heard of it. This reality is the inheritance of Schrödinger's cat, and it is also one of the ultimate criterion numbers that every quantum computer is qualified to store in the core solid-state, so I can tell you - let's start with the simplicity, the wave-particle duality of light, we should know, right? ”

"Nonsense, I briefly mentioned it in physics class last semester, and I should have been curious to read some materials in my later life. Isn't it that in the standard double-slit interferometric reality, when a photon passes through the first set of slit, its behavior shows the physical property of propagating in the form of particles? But when the second set of slits behind the first set of slits is introduced, the light rays passing through the two sets of slits begin to take on the physical properties of propagating in the form of waves.

Whether each photon behaves as a wave or a particle seems to be related to the means by which they are observed - whether you are looking behind the first set of slits or behind the second set of slits. At the microscopic quantum level, it seems that this is also a circumstantial evidence of Schrödinger's cat. ”

"That's good, but I can tell you more than that." Hatsune Niang praised Gu Mojie, and then eloquently said a piece of knowledge that almost subverted Gu Mojie's cognition.

"The 'laser pseudo-double grating penetration test' that I mentioned earlier is an improved implementation that further validates this theory, and was done by a group of scientists in the future - I mean after 2012.

That group of scientists had a deep understanding of quantum physicist John Murphysicist. Wheeler's 1978 theoretical hypothesis of 'delayed choice thinking real yàn' was put into practice, using a helium atomic beam to simulate a beam of light in a double-slit real yàn, and a pseudo-grating was made with a specific pure laser beam that would not interfere with the movement of the helium atomic beam in any way - this pseudo-grating could serve as a grating observation, but would not block the helium atomic beam like the solid grating.

For example, if the physical grating is a door with card access control, then the door can not only block people's access, but also record people's access; The pseudo-grating is equivalent to an alarm with an infrared beam, and the entity without a door will not block the passage of people, but it can retain the function of recording the passage of people - guess what scientists see after adding this pseudo-grating? ”

Gu Mojie was a little impatient, his curiosity had been fully mobilized, and he asked in a muffled voice: "Don't sell it, say it quickly." ”

Hatsune-nün's artificial intelligence seems to have evolved a somewhat coquettish tone, snorted in dissatisfaction, and continued to state: "They found that if there is only a solid slit grating behind the pseudo-grating, then the helium atomic beam will appear to be a particle when it passes through the pseudo-grating; If there are two solid slit gratings behind the pseudo-grating, then the helium atomic beam will be characterized as waves. ”

"What's so strange about that? Doesn't it fit in well with wave-particle duality? One grating, the table xiàn is the grain, two grating, the table xiàn is the wave - and so on! Wrong! ”

Gu Mojie was halfway through speaking, and suddenly realized something, and asked emphatically, "You just said that wave-particle duality was observed in the pseudo-grating before the guò entity grating?" ”

"Yes, that's what it means, it seems that you have understood the deeper meaning of the quantum world."

"You're saying, 'Not only have the light waves used to pass through the environment, but they will also make choices about their final state of affairs; Moreover, the environment in which light waves are about to pass through guò in the future and have not yet passed through guò will also have a selective influence on the physical state of the present moment itself'? That is, it is not the past plus the present that determines the future, but the past plus the future that determines the present? ”

“BINGO！ That's right -- at least at the quantum microscopic level, and that's John. Wheeler's 'delayed choice of thought is real' and was finally proven. At the moment when time is infinitely differentiated, each present state is determined by the past moments and future moments adjacent to it, rather than the simple past plus present that determines the future as macroscopic physics believes. At the microscopic quantum level, there is an interaction between the past, present, and future – an interaction in the universe, all of which are interactions, with gravitational forces, electromagnetic forces, strong interactions, and weak interactions, with no exception.

Macroscopic physics only thinks that the present and the past will act on the future, but does not admit that the future will also act on the present together with the past, and this is the biggest obstacle. The effect of the two points on the timeline is also mutual, but the macrocosm cannot observe the reaction of the future to the present because of the continuous separation of parallel time and space. ”

"Therefore, it is also because of this law of nature that after I am reborn, those objective knowledge that will not change by my will, those things that are not transferred regardless of the interaction between the past, the present and the future, can remain in my mind. And the things that can be changed are obliterated by the effect of my rebirth, so the memories associated with them will also be blurred - because those things can happen and they may not happen - is that right? ”

"That's it, so it's hard for you to take advantage of the prophets of 'historical events' that haven't happened yet - don't you suddenly find your life more challenging than the rebirths you see in time-traveling novels?"

"What is a time-traveling novel? How come I don't remember? I don't seem to have read a single one of them - oh, are you talking about something like Mark Twain's "The Men of Connecticut in Arthur's Dynasty" or Huang Yi's "The Search for Qin"? ”

"Looking for Qin" is a work written by Hong Kong writer Huang Yi in 1991, and Gu Mojie, who is now in his third year of high school, has read it. Therefore, he can probably understand the concept of "time-traveling novels" without the knowledge of later generations, even if there were no time-traveling novels at the level of online literature in 2002.

"I'm sorry I can't answer that question because I don't know either." Hatsune reluctantly ended the conversation.

Gu Mojie put down Hatsune Niang and rested on the pillow, trying to sleep well again. Before turning off the lamp, he picked up the note he had written "Be careful of SARS ......" that he had written before his memory dissipated and looked at it again and again, but he couldn't remember that the note was trying to remind him of something.

It's a wonderful feeling, a race against your own memories that are rapidly fading with pen and paper. Gu Mojie felt that the note he wrote a few minutes ago was as mysterious as the bloody clues left by the deceased before they died in "Detective Conan".
