Chapter 5 Bell’s Inequality
"Eh? You live next door?"
Liu Xiaoke was holding the key to open the door, and looked at Wang Yi who was coming out to throw away the garbage next to him and turned his head and said with some surprise.
Wang Yi also opened the door after hearing her return. After all, she had helped him and he was a new neighbor. Of course, the most important thing was to ask for the wifi password. After all, he had to pull the network cable tomorrow.
"Yes, and thank you for your help today. Please add me as a friend. If you have any trouble, you can come to me."
Wang Yi shook the phone in his hand.
"I didn't expect that you look so young, but you have so many tricks up your sleeve."
Liu Xiaoke had a look on her face. As a beautiful woman, she was often approached by various excuses to signal her, but she did not reject Wang Yi's move to become a friend. Somehow she felt that she was not mature enough at her age to be deceived by a pyramid scheme. The little boy who left had a natural sense of trust.
"That's right, Sister Xiaoke is a great beauty."
At this time, Wang Yi would naturally not ask for trouble and say that I was asking for the wifi password.
"By the way, how much is the wifi? I can't connect the network cable until tomorrow."
Wang Yi casually stated his main purpose.
"Bababa, I want to watch a TV show tonight, so don't download movies."
"No, thanks."
After saying that, Wang Yi threw away the trash and returned to the room.
After connecting to wifi, Wang Yi logged into the student account of his alma mater, the Academy of Sciences.
You can also use the school's database after graduation, which is definitely a benefit for those who need it. Every school has to pay a large fee for the database every year, and these are free and open to students.
Otherwise, once an individual downloads the required information, he or she will be charged, and many still charge US dollars.
The protection of intellectual rights and interests in this world is quite good.
Then Wang Yi began to search for the papers he needed and downloaded them, all of which were related papers on quantum mechanics.
In the three years in the magical world, with the help of Overclocking, he was able to absorb a huge amount of knowledge. When studying, he would also encounter various stucks. With Overclocking's recall, he could determine the places where these stuck and the functions here. Quantum mechanics has some inextricable connections and complementarities.
But it is a pity that in the past, he focused on algorithms and electronics. It can only be said that he has heard some general ideas about quantum mechanics, but now he has begun to make up for it.
First, read through all the things summarized by previous people to see if you can get inspiration and help.
In addition, he also completed the submission of his first manuscript.
A paper on pure number theory, about the proof of Goldbach's conjecture (please don't touch me, I can't prove it).
The reason why Wang Yi can study mathematics is related to one of his self-created magic models.
Because he had been staying in the mage tower, Wang Yi was seriously lacking assistants, which made him pay attention to the undead, and finally he focused on the skeleton.
But ordinary skeletons are too rigid, and the summoning process is too simple. Because of this simplicity, Wang Yi feels a little unable to start.
In the end, he learned from the painful experience and relied on overclocking and his own mathematical skills combined with the practice of spell models, combined with some mathematical theories from other worlds to complete the collision of the sparks of the two civilizations, allowing him to complete the process of 'because...so', thus conducting the summoning of skeletons. improved.
The conjecture itself is one of the achievements, but in fact the most important thing is the mathematical tools improved by combining some novel ideas from other worlds.
Now Wang Yi has been able to give certain specific programs to skeletons and let them do specific things, which is far beyond the original ability of the spell model called Skeleton Summoner.
Therefore, he was naturally fully confident about this paper, and he was quite comfortable writing it. As long as he paid attention to some mathematical insights from other worlds and needed to complete the proof process.
After looking at the SubmittedtoJournal prompt, it means that the submission has been successful, and the next step is to wait.
For such a huge proof, the review will definitely be very cautious, and it is quite normal for more than a month.
Precisely because he knew it would take a long time to wait, Wang Yicai took the lead in sending this out.
As for being famous or attracting attention, Wang Yi doesn't care. Although he does have many secrets, in fact, the impact of this pure number theory conjecture will be limited even if he finally wins an international award for it.
In this era that has just entered the era of smartphones, people who eat melons are more concerned about various celebrities and gossip.
There may be a shock in the academic world, and it may also attract the attention of your alma mater and some higher-ups, but the attention that can be attracted in the field of number theory is relatively controllable.
It's not like he pulled out a perpetual motion machine.
It's just that Wang Yi was a completely pragmatic person in the past, and he always used ready-made knowledge to learn. His papers were just coping, and he lacked experience in this area.
This kind of paper in the field of pure mathematics should have been better submitted to a professional journal in the field such as "Annals of Mathematics", but he submitted it directly to the "Science" of this world.
And this famous "Science" itself is also the hardest hit area by civil science bombing. Goldbach's conjecture receives almost as many submissions every year as the perpetual motion machine.
The title chosen by Wang Yi perfectly fits this point...
Wang Yi, who didn't know much about this aspect, put it aside after completing these operations and began to focus on some papers he needed.
Directly turn on overclocking and read while reading. With the extra time, you will gradually start to understand the relevant papers.
In the end, he focused on Bell's inequality, a major doubt he encountered.
Does God throw the dice?
This problem has also been plaguing mages from other worlds. A group of people support that everything in the world completely follows certain laws, without exception.
It is impossible to predict that there are still some hidden variables that have not been discovered or noticed.
The other batch was the complete opposite.
This can be said to involve the issue of the law of cause and effect, and mages attach great importance to this, because they can really take advantage of it.
"Good guy, can a formula be established in this way? Can it be verified in this way? Sure enough, some problems themselves only need to poke through a layer of paper windows."
Bell's inequality itself is not complicated, but it is precisely because of its relative simplicity that it becomes more important. Mathematics does not lie.
In the 1980s, the second generation of testing instruments had almost completed the falsification of Bell's inequality.
The third generation of inspection instruments is more accurate.
But for Wang Yi, what he needs more is this idea and verification process to verify his magic side troubles.
He can use similar experiments to complete the verification of his troubled problems!
This gave Wang Yi a sense of relief that he was about to pursue the truth.
Many people have heard of quantum entanglement, which means that entangled photons can determine the state of the other through one. Both Bell and Einstein believed that this was actually because the photons were given certain information from the beginning, or that they followed a certain The formulas and rules are all hidden variables written in advance, so that the entangled photons can be in sync, and there is no connection between the entangled photons.
Bell specially came up with Bell's inequality to support Einstein. If it is true, Einstein is right, and there is indeed some kind of hidden variable.
To verify this is to first assume that there are hidden variables and then design an experiment to prove or falsify.
Because photons are still electromagnetic waves and have wave characteristics. Waves have amplitudes and polarization directions. Therefore, different polarizers can be used to allow entangled photons to "answer questions", and statistics can be made based on the different results of different photons on different polarizers.
Relying on high-precision experiments and increasing the amount of data collection, Bell's inequality can be statistically integrated into Bell's inequality to see if the statistical results are consistent, thereby determining whether the photon has been written into some hidden variable in advance or not...< br>
This made Wang Yi's eyes glow with arcane brilliance, and his heart surged.
"Sure enough, the most brilliant essence of a civilization is the knowledge summarized by this civilization."
Bell's inequality is not complicated, nor is the principle of the experiment. The most difficult thing is accuracy and instrumentation. But this seemingly simple inequality and experiment, this fantastic idea can solve the most cutting-edge problems.
Now that someone has completed the verification of the quantum world, what remains is Wang Yi’s verification of the magic world...

However, because there are too many trivial matters in life now, almost all the extra time is spent on coding, so moral integrity rarely bubbles up (end of chapter)
