Su Yun smiled, nodded and said:

"That's right, if you follow your previous theory, then when the an-i power of 2 splits, the meaning of the Dirac function you proved satisfies orthogonal normalization does not exist. ”

Shu Mengmeng turned around and looked at Su Yun with a look of adoration:

"Wow, big brother, you're so good! Better than those old grandfathers!"

Although I don't know who those old grandfathers are, but being praised by others, Su Yun is still in a good mood.

Su Yun said patiently:

"In fact, when studying quantum mechanics, we can change the perspective. ”

Shu Mengmeng began to listen patiently this time, and Su Yun compared his hand to a box and said:

"There was a cat in a box, as well as a small amount of radioactive material. After that, there is a 50% chance that the radioactive material will decay and release poison gas, killing the cat, and a 50% chance that the radioactive material will not decay and the cat will survive. ”

Su Yun glanced at Shu Mengmeng and asked:

"So, after a certain amount of time, is the cat alive or dead?"

Shu Mengmeng lowered her head, frowned, and bit the nail of her thumb in her mouth.

Su Yun was not in a hurry, just waiting quietly, Shu Mengmeng suddenly raised her head and said cutely:

"Alive, and dead?"

Su Yun gave her a thumbs up in her heart, she was not a genius girl.

"That's right, if we don't open the box, the cat will either die or live. These are its two eigenstates, and it can also be said that it is in a superposition of living and inactive. We can only know for sure whether a cat is dead or alive the moment we lift the lid. ”

In the distance, Student A: What is it? alive and dead? a superposition of living and not living?

Student A was a little speechless, originally he took advantage of this time when there were not many people in the library, and wanted to read a book here quietly, but by coincidence, he met two unqualified people discussing in the library.

And these two people said all the things he didn't understand.

Student A is very angry now! very angry! The kind that wants to hit someone!

Since he was a child, he has always adhered to the concept of wanting to teach a person a lesson, don't talk nonsense, go up and punch him first, so that he can always remember the lesson.

So he put away the book and walked to Su Yun again, who was still talking.

"According to quantum mechanics, the cat in the box is in a 'dead-alive superposition'——— both dead and alive. It is not until you open the box and look at the cat that you decide whether it lives or dies. ”

Boy A walked up to Su Yun, reached out and wanted to grab him by the collar, and then punched him.

His height of 185 is nearly a head taller than Su Yun, is he hanging steadily?

Syllable!

His wrist was grabbed by Su Yun, it hurt!

Student A: "。。。。。。 ”

"It's important to note here that we don't find out but decide, and just one look is fatal. That is, when we open the box, the superposition state suddenly ends and collapses. ”

In physics, there is no formula that describes this kind of collapse, so in mathematical terms, it is called the collapse of the wave function. ”

Su Yun said that Shu Mengmeng had been listening carefully, thinking carefully and digesting what Su Yun said.

Su Yun turned his head, looked at the boy A next to him, and asked:

"What's the matter?"

Boy A:

“。。。。。。 ”

He was already crying, and when this man grabbed his hand, it was like an iron plie, and no matter how hard he tried, he couldn't take it back.

The most important thing is that it hurts very much!

Student A looked at his hands and said without tears:

"That classmate, can you let go of your hand first?"

Su Yun suddenly realized, let go of his hand, and said without any apology at all:

"Oh, sorry, forgot. What's the matter?"

Boy A:

“。。。。。。 ”

Since he was a child, he has always adhered to the concept of a gentleman who speaks but does not use his hands.

If you want to teach a person a lesson, there are many ways, they are all adults, why do they have to shout all day long?

At that moment, he decided that the hero would not suffer the immediate loss:

"Hehe, it's nothing, I'm just curious about what you're talking about, it's nothing, then I'll go first. ”

"Oh. ”

Hehe, if you say slip, the gentleman will take revenge, ten years is not too late.

He has decided that he must go to all the places where he can complain to the school and write a letter to complain about him!

..........

The next day, Peking University officially opened.

Su Yun didn't go to class today, but came to the sixth floor of the library early.

Su Yun was sitting in Area B on the sixth floor, and suddenly shouted loudly:

"Hey, which district are you in?"

Students reading books in Area B:

“.........”

A cute shout came from a corner of the library:

"I'm in Zone D! What's the matter with Big Brother?"

Students reading books in Zone D:

“.........”

Su Yun:

"I have an idea for that question you asked me yesterday! Come here, I'll tell you! By the way, help me find some books on nuclear physics!"

Meng Meng:

"I know, big brother, I'll be right here!"

ACEFGH.... District readers: ??????

What's going on? Why are you still yelling? Is this the library? Is it the wrong way we entered the library today?

After a short period of silence, Meng Meng ran from Area D to Su Yun's Area B.

"As you said yesterday, there is a small loophole in the uncertainty principle, and I've figured out how to close it, you see. As soon as the two met, Mengmeng sat beside Su Yun obediently.

Su Yun took out a pen and paper and began to write:

"It is impossible for a microscopic particle to have definite values for certain physical quantities, such as position and momentum P, or azimuth α and momentum moment L, as well as time and energy. ”

Meng Meng is puzzled:

"Why is it impossible? People think that when one of the values is determined, the other values will become shaky or more explicit, just like the cat's problem that the big brother said yesterday, when a certain value is determined, whether it is micro or macro, doesn't it collapse immediately? From 0 to 1, that's probably what it means?"

Su Yun nodded and explained:

"It's because, look here........"

..........

Day 3, 6th floor of the library.

"Big brother, big brother, let's see if my theory is correct!"

"Hmm... Let me see.... Yes, your idea here of a probability amplitude function with the conjugate quantity as the independent variable is very good, yes! Here we can do that, you see here, can we do this and ..... like this?"

"Wow! really! I didn't even expect it! Big brother is so amazing!"

The people reading books on the sixth floor:

“.........”

Day 4, 6th floor of the library.

"Big brother! Big brother! I proved that theory yesterday! Look at it!"

"Hmm... I'll see, yes, that's right!"

"yes! It's finally proven! Can I move on to the next stage?"

"Not yet, you see that you still have three theories missing in front of you to support your final results, and these three theories, we need to prove this one first...."

"And then ......... like this"

"And then ...... like that"

"Wow! Big brother is amazing!"

The people reading books on the sixth floor:

“.........”

Day 5......

Article 6 .......

Day 7.....

Principal's Office.

It's been a week since school started, and Zhang Jianguo has also returned to school from his original idle days to deal with official business.

However, he didn't expect that after only a week of coming back, someone would stab him.

Library director Zhao Qidong sat on the sofa next to him, his face ugly.

"Look at this Su Yun!Ahh

After taking a sip of water, Zhao Qidong slapped the table and continued:

"Look at the complaint letters on this table, look at these! Ahhhhhh

Zhang Jianguo sat on the side, his face full of helplessness, wanting to cry without tears.

"Lao Zhao, it's almost done...."

When Zhao Qidong heard this, he became even more popular.

"Didn't I say it, Lao Zhang, you had to stuff him into my library at the time, and now you look at my pile of complaint letters, ah? I can't talk about it yet? I'm angry with me!"

Zhang Jianguo shook his head, walked to a cabinet, opened the cabinet, and envelopes poured out of it.

Zhao Qidong:

“。。。。。。。。 ”

Zhang Jianguo smiled bitterly:

"Lao Zhao, I don't know how many times you're here!"
