Chapter 823： Academic exchange!

"Well, we have academic exchanges, we have said that, the rules are still the old ones."

Liu Shuren smiled coldly and said: "We, each of us, take out an academic question, and test each other. If the other person can answer it, they will ask the person on our side a question. Of course, the premise must be said. It could be an academic-related issue. Also, President Wang, I know that your school is not strong, but we are all for academic research. If we want to say it, we don’t have to be impatient if we lose."

When Jiang Chen heard it behind, he almost laughed.

As soon as I heard it, I knew that Liu Shuren and Principal Wang were old friends.

There have been a lot of struggles between the two sides before, and the feeling of President Wang has been anxious a lot.

Jiang Chen: →_→.

Principal Wang said angrily: "What does it mean that our school is inadequate? What kind of **** are you? Humph! Since you are so awesome, come on. I don't believe it!"

"By the way, what about Jiang Chen, which is very popular in your Minsheng University recently?"

Liu Shuren snorted coldly from his nostrils: "That Jiang Chen, isn't it that Jiang Chen can attract millions of fans in two online courses? Isn't it a folk academic who claims to be omnipotent and omniscient? I said, your Minsheng University is so bad What kind of academic talent can the school cultivate? Wouldn't I take someone to look at it?"

Although President Wang doesn't like Jiang Chen that much, but Jiang Chen represents his image of Minsheng University.

This Liu Shuren humiliated Jiang Chen so publicly, wouldn't it be the same as humiliating Minsheng University?

Suddenly angry!

(One "an angry)!

Principal Wang: "Huh! You guys look down on others, you are so deceiving!

What people can be cultivated by Minsheng University? Today, let you see and see, the talents we have cultivated! Jiang Chen? Where is Jiang Chen? "

Jiang Chen: "How do you feel that in the Three Kingdoms period, two big men called for battle and sent generals to go heads-up?"

Jiang Chen walked out.

Liu Shuren proudly said, "Will you leave your name?"

Jiang Chen almost fell to the ground.

Are you two playing the Three Kingdoms Strategic Edition every day?

Come on, how much does the Romance of the Three Kingdoms give you?

I give it double!

"I am Jiang Chen!"

Jiang Chen said lightly.

Liu Shuren, looking up and down Jiang Chen, suddenly burst into laughter, and laughed at the doctoral professors behind him: "This is Jiang Chen, who has recently exploded on the Internet. That tutoring teacher. Hey, can't you think of it? He is actually the people's livelihood. A 7-year-old squatting student who has been repeating a grade at university!"

The academic gods of the research institute are almost all big cows of Shuimu University and Imperial Capital University. When they heard this, they couldn't help laughing.

"Squatting for 7 years?"

"I didn't have much confidence in the first place, and I was a little worried. I heard the resume of my opponent, and my waist and legs didn't hurt anymore!"

"Unexpectedly, never expected!"

"Squatting class 7-year repeater? That's interesting!"

A bunch of people are mocking Jiang Chen.

The smile on Jiang Chen's face was still bright, as if he hadn't heard these people at all.

Principal Wang felt regretful for a while.

Knowing that Jiang Chen's identity would be ridiculed like this by the other party, he directly refused!

This Liu Shuren is really bullying!

He said helplessly: "Liu Shuren! The so-called hero doesn't ask where it comes from, why do you want to get to the bottom of it? Humph, even if you are awesome, you have to win against Jiang Chen first!"

"Good!~"

Liu Shuren didn't pay attention to Jiang Chen at all. In his opinion, how could an old scumbag who could not graduate after 7 years of studying at Minsheng University be awesome?

Overtake your own academic master of the Institute of Physics, Chinese Academy of Sciences

This is impossible!

He was full of confidence and sneered: "Well, if that's the case, then do it! I won't bully you, so, I will send a doctor first and then fight Jiang Chen with you?"

President Wang was overjoyed. Just as he was about to say something, Jiang Chen lazily said: "What postdoctoral? Who do you look down on? To fight, ah, it's academic communication. Of course, it's to mobilize your strongest scholar. Compete with me."

Principal Wang: ~ Nima!

Jiang Chen, you are afraid that because of your own strength and the gap with others, you don't have a B number in your heart, right?

This is from the Institute of Physics, Chinese Academy of Sciences!

All of them are learning gods and masters, and you can’t get in if you don’t have the ability, okay?

The other party was finally careless and asked a doctoral student to PK with you. This is really a good opportunity for our Minsheng University to save face.

As long as Jiang Chen wins the opposing postdoctoral fellow, President Wang will immediately announce the end of the exchange!

Never give Liu Shuren a chance to find his place.

But Jiang Chen refused the other's kindness? Still provoke each other?

Let them go directly to the most powerful god?

Isn't this looking for death?

Principal Wang cried in his heart.

Liu Shuren's face couldn't hold it anymore: "Don't you want to face it? Okay, take your own shame! Then don't blame me! Come on! Liu Shuyun, give it to me!"

When Liu Shuyun listened to his name, he knew that he had a close relationship with Liu Shuren.

In fact, this is the cousin of Liu Shuren, director of the Institute of Physics!

He is also a well-known advanced physics expert in the Institute of Physics.

Still a very famous mathematician!

A middle-aged man wearing glasses came out, resembling Liu Shuren by three points, and said straightforwardly: "Brother Jiang, then I'm not welcome. Let me ask you a question, what's the matter with quantum entanglement?"

Jiang Chen said without thinking, "According to the ScienceDaily website, scientists at the Jet Power Laboratory of the National Aeronautics and Space Administration (NASA) discovered that the mysterious quantum entanglement state is related to the motion of the observer relative to the microscopic particles. This kind of quantum entanglement It can be produced or destroyed by the relative motion of the observer. This obviously violates Einstein’s special theory of relativity that the speed of light is insurmountable. Therefore, when he derived this conclusion from the quantum mechanics theory, he did not believe it. This phenomenon really exists, but trying to use this conclusion to prove the unreasonableness of quantum mechanics, and called it a "ghost-like" connection. However, later experiments proved that this quantum entanglement phenomenon does exist. It is The basis for the popular quantum superluminal transmission research."

Jiang Chen said eloquently: "Understanding how some particles that are not entangled at rest can obtain quantum entanglement only through motion. There may be many potentially important applications. For example, entangled particles can be used to calibrate atomic clocks. The travel of spacecraft in the depths of space is very important. In addition, quantum entanglement plays an important role in both quantum communication and quantum computing, and this discovery will also have an important impact on these fields. Quantum entanglement states have been scientists so far A phenomenon that we still cannot explain satisfactorily. It implies that the ability to connect things may be far beyond the understanding of modern science. An understanding of its nature may enable modern science to make major breakthroughs on some key issues."

The other party was shocked:..."

Although the concept of quantum entanglement has long been known in the field of quantum mechanics research, as a 7-year veteran, can Jiang Chen actually understand this?

Jiang Chen asked in turn: "Then what is quantum superposition?"

The other party sweated, and hurriedly tried to recall: "Quantum superposition and quantum entanglement are very abstract concepts in quantum mechanics, and even no one can truly understand the mystery."

Jiang Chen smiled: "Well, if no one can understand its accurate concept, how can this concept be proposed?"

The other party is speechless.

Jiang Chen calmly said: "The so-called quantum superposition state is described by an interesting thought experiment of the "Schrodinger Cat". Suppose that when a cat is enclosed in a box with unknown internal information, a gun is used to the box. Shooting, if only one bullet is fired, and the cat is either dead or alive at this time, the quantum state of the cat at this time is a mixture of the dead cat state and the live cat state (because people cannot accurately know the state of the cat at this time). The state will cause quantum entanglement, which has become one of the basis for quantum random events."

"The meaning of the principle of superposition of quantum states is: in quantum mechanics, the totality of state functions of a system is described, and a linear space is opened. Quantum mechanics is expanded in this space. The principle of superposition of states can be expressed as: the state of a physical system is determined by the hope Vector description in Albert space."

The other party was speechless!

The boss of Professor Deer's beautiful eyes!

Unexpectedly~~

Jiang Chen's performance is so awesome?

Directly using quantum mechanics, the other person who asked was dumbfounded?

This is too awesome, right?

Jiang Chen continued to chase after victory: "Then do you know, what is quantum collapse?"

The cold sweat on the opponent's forehead.

Jiang Chen curled his lips and said, "The concept of quantum collapse means that you don’t observe it, and you don’t know what movement it made. Once you observe, you can only see the state before it disappears. The most deadly thing is every The state of disappearance is not the same. It probably means that. In fact, what I want to say is whether this kind of present is a time travel."

He blinked.

Seeing Jiang Chen's victory, Lu Lingxi became curious and couldn't help asking: "Then I want to ask, what is the matter, what is it, and why is there such uncertainty?"

Jiang Chen said lightly: "Scientists discovered a strange phenomenon in the process of studying quantum, that is, every time they observe a quantum, the state of this quantum is different from before. It gives people the feeling that human observation affects the state of quantum. .

Therefore, scientists have put forward an inconceivable point of view, that is, when you don’t observe this photon, it is in an incomprehensible state of uncertainty (also called a superposition state), that is, a photon passes through the left and right narrows. These two possibilities of the slit exist at the same time, and when you observe it, you can always only find the photon in one slit, and it does not become two. "

"So scientists boldly speculate that people's conscious choices and observations actually determine the final state of a quantum. That is, when a quantum is not measured or observed by humans, it exists with many possibilities at the same time, and once it is observed, it will be immediately random. It is determined that a form will continue to exist."

"This is why we think that quantum mechanics is a kind of metaphysics!"

"but!"

Faced with so many bewildered academic bulls, Jiang Chen talked freely: "Why do quantum superposition and quantum entanglement make people more confused? Because in the process of human exploration of the universe, the difference between the microcosm and the human world is more than 10^15 orders of magnitude; the scale of the human world and the vast universe differs by more than 10^20 orders of magnitude. Such a huge difference is destined to be fundamentally different in the laws of the micro, macro, and vast universe."

"We are so used to studying the world we see before our eyes!"

"For our unknown world, the universe, for example, our imagination is too scarce. Just like an ant, no, a bacterium, can't imagine the human world like! Even if the truth of the universe is before us, we think The comprehension ability may not be able to see through!"

"The world that we humans adapt to is the classical world of Newtonian mechanics. Our way of thinking is also the way of thinking in the classical world. Therefore, it is difficult to adapt to the laws of the microscopic world. In the microscopic world, quantum superposition, quantum entanglement, and Schrödinger The cat and the uncertainty principle are difficult to understand; in the vast universe, dark matter, dark energy, and black holes are difficult to understand; perhaps it reflects the limitations of human thinking."

As soon as Jiang Chen's voice fell, Lu Lingxi couldn't help standing up and applauding Jiang Chen~

"Bravo!"

Principal Wang was also dumbfounded and dumbfounded~~

This, is this a student in our school who has been in class for 7 years?

Is this a scumbag who can't pass every year in physics and high math?

Is this too awesome?

At this moment, Principal Wang himself was moved in a complete mess!

If the repeaters in our school have this level, who is the Minsheng University afraid of?

This kind of super master who is so proficient in physical quantum mechanics and can explain in simple terms, I am afraid that only the likes of Einstein and Hawking can do it, right?

Whatever you want, any student in our school who is squatting in class can come here at his fingertips and speak clearly, which is even more powerful than those of the big cows!

President Wang also stood up and applauded Jiang Chen.

Opposite, Liu Shuren from the research institute is dumbfounded~~

Liu Shuyun grew his mouth wide.

Liu Shuren asked Liu Shuyun: "What he said, right?"

Liu Shuyun nodded like garlic: "Dean, what he said~~Yes, yes! That's right!"

Liu Shuren: "???"

Liu Shuyun wished to kneel down for Jiang Chen, his eyes gleaming and said: "I have studied quantum mechanics for so many years, and no one has ever been able to speak so clearly! So thorough! I admire you so much! You are my teacher! "

As he said, he went straight up and held Jiang Chen's hand judgment tightly.

Jiang Chen: "...Khan!"

It's disgusting!

Why are you holding my hand so tightly?
