Chapter 5: Bell's Inequality
"Huh? You live next door, huh? ”
Liu Xiaoke was opening the door with the key, and looked at Wang Yi, who came out to throw garbage next to him, and said with some surprise.
And Wang Yi also specially heard that she opened the door after she came back, after all, people helped themselves, or new neighbors, of course, the most important thing is to ask for the wifi password, after all, the network cable has to be tomorrow.
"Yes, thank you for your help today, add a friend, you can find me if you have trouble."
Wang Yi shook the mobile phone in his hand.
"I didn't expect you to look young, but there are quite a lot of routines."
Liu Xiaoke had a look of seeing through it, as a beauty, she was naturally often accosted by various excuses to shake the signal, but she did not reject Wang Yijia's friend's move, somehow she felt that she had a natural sense of trust in this little boy who was deceived by a pyramid scheme at a young age.
"That's it, Sister Xiao Ke is a big beauty."
At this time, Wang Yi naturally won't find himself boring and say that I am for the wifi password.
"By the way, how much wifi do you have, I can pull the network cable tomorrow."
Wang Yi casually stated his main purpose.
"Eight eight, I'm going to catch up on the drama at night, don't download the movie."
"No, thanks."
After finishing speaking, Wang Yi threw away the garbage and returned to the room.
After connecting to wifi, Wang Yi logged on to the student account of his alma mater, the Academy of Sciences.
After graduation, the school's database is also a benefit for those who need it, and each school has to pay a large fee for the database every year, and these are free for students to use.
Otherwise, once an individual downloads the required information, there will be a fee, and many still charge American knives.
The world is quite well protected for intellectual rights and interests.
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 wizarding world for three years, with the assistance of overclocking, he was enough to gnaw through a huge amount of knowledge, and when he delved, he would encounter all kinds of jams, and by recalling the overclocking, he could determine that these jammed places were inextricably linked and complementary to the quantum mechanics here.
But it's a pity that in the past, he focused on algorithms and electronics, and quantum mechanics can only be said to have heard some roughly, and now he is starting to make up for it.
Let's first read all the things summarized by the predecessors to see if we can get inspiration and help.
In addition, he also completed the submission of the first manuscript he made.
A paper on pure numbers, a proof of Goldbach's conjecture (don't bother me, I can't prove it).
The reason why Wang Yi studied mathematics was related to one of his self-created magic models.
Because he had been in the Mage Tower, Wang Yi was seriously lacking assistants, which made him pay attention to the undead, and eventually he focused on the skeletons.
But ordinary skeletons are too rigid, and the summoning process is too simple, and it is precisely because of this simplicity that Wang Yi feels a little at a loss.
In the end, he relied on overclocking and his own mathematical skills to cooperate with the practice of spell models, combined with some mathematical theories from the other world to complete the collision of the sparks of the two civilizations, so that he completed the 'because...... So's process, thus improving summoning skeletons.
Conjecture itself is one of the achievements, but in fact, the most important thing is the mathematical tool perfected by combining some novel ideas from the other world.
Now Wang Yi has been able to assign certain specific programs to skeletons and make them do specific things, far beyond the original ability of the spell model of summoning skeletons.
Therefore, he naturally has a full grasp of this paper, and it is quite handy to write, as long as he pays attention to some otherworldly mathematical experience, he needs to complete the proof process again.
After looking at the prompt of Submitted to Journal, it means that the submission has been successfully submitted, and the next thing is to wait.
With such a big explosion of proof, the audit will definitely be very cautious, and it will be quite normal for more than a month.
It was precisely because he knew that he would have to wait for a long time that Wang Yi took the lead in sending this out.
As for being famous or not, Wang Yi doesn't care, although he does have a lot of secrets, but in fact, this kind of conjecture in pure number theory, even if he finally wins an international award because of this, the impact is actually limited.
In this era that has just stepped into the smartphone, the people who eat melons are more concerned about various celebrities and gossip.
There may be shocks in the academic world, and it may also attract the attention of your alma mater and some attention from the upper echelons, but the attention that can be attracted in the field of number theory is relatively controllable.
It's not like taking out a perpetual motion machine.
It's just that Wang Yi used to be a complete pragmatist, and he used ready-made knowledge to learn, and his own papers were only coping with it, and he lacked experience in this area.
This kind of paper in the field of pure mathematics should have been submitted to a professional journal in a field such as the "Annals of Mathematics", but he went directly to the "Science" of this world.
And the famous "Science" itself is still the hardest hit area by the bombing of civil science, and the Goldbach conjecture receives a large number of submissions every year, almost like the perpetual motion machine.
Wang Yi's title fits this point perfectly......
It's just that Wang Yi, who didn't know much about this aspect, threw it aside after completing these operations and began to pay attention to some of the papers he needed.
When overclocking is turned on directly, you will start to gradually understand the relevant papers while looking down.
Eventually, one of his major doubts settled on the 'Bell Inequality'.
Does God drop the dice!
This question has also been plaguing the mages of the other world, and a group of people support that everything in the world follows a certain law exactly, without exception.
It is impossible to predict that there are just some hidden variables that have not been discovered and perceived.
The other batch is diametrically opposed.
This can be said to involve the problem of the law of cause and effect, and the mages attach great importance to it, because they can really be used.
"Good fellow, so you can make a formula? So that it can be verified? Sure enough, some of the problems themselves only need to puncture a layer of paper windows. ”
Bell's inequality itself is not complicated, but it is all the more important because of its relative simplicity, and mathematics does not lie.
In the eighties of the twentieth century, the second-generation inspection instruments had almost completed the falsification of Bell's inequality.
The third generation of inspection instruments is more precise.
However, for Wang Yi, what he needs more is this idea and verification process to verify his magic side troubles.
He could have used a similar experiment to verify his troubled problem!
This gave Wang Yi a sense of comfort that he was about to pursue the truth.
Many people have heard of quantum entanglement, that is, the entangled photons can determine the state of the other through one state, Bell and Einstein both believe that this is actually the photons are given some kind of information from the beginning, or they follow some kind of formula and law, are pre-written hidden variables, so that the entangled photons are in lockstep, and there is no connection between the entangled photons.
In order to support Einstein, Bell specially came up with Bell's inequality, and if it is true, Einstein is right, and there is indeed some kind of hidden variable.
To verify this, we first assume that there are hidden variables, and then design an experiment to prove or falsify.
Because photons are still electromagnetic waves, they have wave characteristics, and the wave has amplitude and polarization direction, so different polarizers can be used to make the entangled photons 'answer the question', and the different results of different polarizers can be counted by different photons.
Relying on high-precision experiments and increasing the amount of data collection, we can statistically apply it to Bell's inequality to see if the statistical results are consistent, so as to determine whether the photon has been written into some hidden variable in advance or not......
This made Wang Yi look at the arcane brilliance in his eyes, and his heart was surging.
"Sure enough, the most brilliant essence of a civilization is the knowledge summed up by this civilization."
Bell's inequality is not complicated, the principle of the experiment is not complicated, the most difficult thing is only the accuracy and the instrument, but this seemingly simple inequality and experiment, this kind of whimsical thinking can solve the problems that plague the forefront.
Now that someone has completed the verification of the quantum world, the rest is Wang Yi's verification of the magic world......
