Chapter 5 Bell's Inequality
"Eh? You live next door?"
Liu Xiaoke was opening the door with the key. She looked at Wang Yi who came out to throw away the garbage and said with some surprise.
Wang Yi opened the door only after he heard her come back. After all, she was helping him and was also a new neighbor. Of course, the most important thing was to ask for the WiFi password, after all, the network cable had to be pulled tomorrow.
"Yes, and thank you for your help today. Add me as a friend. You can come to me if you have any trouble."
Wang Yi shook the phone in his hand.
"I didn't expect that you look young, but you have so many tricks."
Liu Xiaoke had a look of seeing through everything. As a beautiful woman, she was often approached and asked to shake her signal under various excuses, but she did not reject Wang Yi's action of adding him as a friend. Somehow, she felt that she had a natural trust in this young boy who had been deceived by a pyramid scheme.
"That's right, Sister Xiaoke is a great beauty."
At this time, Wang Yi naturally would not make himself look bad by saying that I wanted the wifi password.
"By the way, what's your wifi speed? I can only pull the cable tomorrow."
Wang Yi casually stated his main purpose.
"Oh, I want to watch a TV series tonight, don't download a movie."
"No, thanks."
After saying that, Wang Yi threw away the garbage and returned to the room.
After connecting to the wifi, Wang Yi logged into his student account at the Science and Technology Institute of his alma mater.
After graduation, you can also use the school's database, which is definitely a benefit for those in need. Every school has to pay a large sum of money for the database every year, and these are free for students to use.
Otherwise, once an individual downloads the required information, they will be charged a fee, and many of the fees are in US dollars.
The world has done a very good job in protecting intellectual rights.
Wang Yi then began to search for the papers he needed and download them. They were all relevant papers on quantum mechanics.
Three years in the magic world, with the help of overclocking, was enough for him to digest a vast amount of knowledge. He would also encounter various problems when studying. With the help of overclocking, he was able to determine that these problems were inextricably linked and complementary to the quantum mechanics here.
But unfortunately, his previous focus was on algorithms and electronics, and he had only heard about quantum mechanics in general. Now he has to start cramming.
First read through what predecessors have summarized to see if you can get any inspiration or help.
In addition, he also completed and submitted his first manuscript.
A paper on pure number theory, about the proof of the Goldbach conjecture (please don't argue with me, I can't prove it).
The reason why Wang Yi studied mathematics was related to a magic model he created.
Because he had been hiding in the Mage Tower for a long time, Wang Yi was seriously lacking in assistants, which made him pay attention to the undead, and finally he focused on the skeletons.
But ordinary skeletons are too rigid and the summoning process is too simple. It is precisely because of this simplicity that Wang Yi feels a little at a loss as to where to start.
Finally, he learned from his mistakes and relied on overclocking and his own mathematical skills to practice spell models, combined with some mathematical theories from other worlds to complete the collision of the two great civilizations, allowing him to complete the process of "because...so", and thus improve the summoning of skeletons.
The conjecture itself is one of the achievements, but the most important thing is the mathematical tools that were perfected by combining some novel ideas from other worlds.
Now Wang Yi can give skeletons certain specific programs and make them do specific things, which far exceeds the original capabilities of the Skeleton Summoner spell model.
Therefore, he was naturally very confident about this paper and was able to write it quite easily. He just had to pay attention to some mathematical experience from other worlds and complete the proof process.
After seeing the prompt "Submitted to Journal", it means that the submission has been successful. The next step is to wait.
For such a big explosion certificate, the review will certainly be very cautious, and it is quite normal to take more than a month.
Precisely because he knew it would take a long time to wait, Wang Yi was the first to send this out.
As for becoming famous and attracting attention, Wang Yi doesn't really care. Although he does have a lot of secrets, this kind of pure number theory conjecture will actually have limited impact even if he wins an international award for it.
In this era that has just entered the era of smartphones, the general public is more concerned about various celebrities and gossips.
There may be some shocks in the academic community, and it may also attract the attention of my alma mater and higher-ups, but the attention that can be drawn to the field of number theory is relatively controllable.
It's not like he took out a perpetual motion machine.
It’s just that Wang Yi used to be a complete pragmatist, who only used ready-made knowledge to learn, and his own papers were just to get by, so he lacked experience in this area.
This kind of pure mathematics paper should have been submitted to a professional journal , but he submitted it directly to "Science" in this world.
The famous "Science" itself is a disaster area severely affected by civilian scientists. The Goldbach conjecture receives a large number of submissions every year, almost like perpetual motion machines.
The title Wang Yi chose perfectly fits this point...
However, Wang Yi, who didn't know much about this aspect, put it aside after completing these operations and started to pay attention to some papers he needed.
Directly turn on the overclocking state, read while downloading, and the extra time will be used to gradually understand the relevant papers.
Finally, he focused on Bell's inequality as a solution to a major puzzle he encountered.
Does God roll the dice!
This problem has also been bothering the mages in other worlds. A group of people support the view that everything in the world follows certain rules completely without exception.
It is impossible to predict because there are some hidden variables that have not been discovered or noticed.
The other group was quite the opposite.
This can be said to involve the issue of the law of cause and effect. Mages attach great importance to this because they can really make use of it.
"Wow, can this form a formula? Can this be verified? It turns out that some problems only require a piece of paper to be broken."
Bell's inequality itself is not complicated, but it is precisely because of its relative simplicity that it becomes more and more important. Mathematics will not lie.
By the 1980s, the second generation of testing instruments had almost completed the falsification of Bell's inequality.
The third generation of testing instruments is even more accurate.
However, for Wang Yi, what he needs more is this idea and verification process to verify his troubles on the magic side.
He can completely use similar experiments to verify the problem that bothers him!
This gave Wang Yi a sense of comfort 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 one another. Both Bell and Einstein believed that this was actually because photons were given certain information from the beginning, or that they followed certain formulas and rules, which were hidden variables written in advance, so that the entangled photons could move in unison. There is no connection between entangled photons.
In order to support Einstein, Bell specially came up with the Bell inequality. If it is true, Einstein is right and there is indeed some hidden variable.
To verify this, we first assume that there are hidden variables and then design an experiment to prove or disprove them.
Because photons are electromagnetic waves with wave characteristics, waves have amplitude and polarization direction, so different polarizers can be used to let entangled photons "answer questions", and statistics can be made through the different results of different photons with different polarizers.
By relying on high-precision experiments and increasing the amount of data collected, we can statistically fit the Bell inequality to see if the statistical results match, and thus determine whether the photon has been pre-written with some hidden variable or not...
This made Wang Yi's eyes bloom with arcane light and his heart was filled with excitement.
"Sure enough, the most brilliant essence of a civilization is the knowledge summarized by this civilization."
Bell's inequality is not complicated, and the principle of the experiment is not complicated either. The most difficult parts are the precision and the instruments. However, this seemingly simple inequality and experiment, this kind of imaginative thinking can solve the problems that plague the most cutting-edge technologies.
Now someone has completed the verification of the quantum world, and what remains is Wang Yi's verification of the magic world...
