Black Technology Live Room

Seeing that Zhang Di was a little hesitant, he was about to agree, but he didn't expect that Zhang Di's expression changed immediately, "Then... let's forget it!"

"Then say this... what?" Lao Liu was about to breathe a sigh of relief, but suddenly realized that Zhang Zhai didn't seem to agree.

"Zhang Zhai! You bastard, don't you understand good words! You don't even help me with this little favor, do you?" Lao Liu yelled, patting the table with his big eyes.

Hearing this, Zhang Zhai was also a little annoyed, but more helpless.

"Old Liu, is this a question of whether I can help? If you say you want a holographic device, I'll get you one. But you insist on asking me to substitute for you! You are not forcing Do cows lay eggs?"

"Let's talk about it! You always taught quantum mechanics, a third-year course, and I'm only a sophomore now, okay, what kind of quantum mechanics do I know..." Zhang Zhai really wanted to cry without tears.

"Does the dean know that you are so nonsense? Old Liu, with so many professors, you can just ask them to give you a substitute class and it's over. It's really not good. Why don't you just come back and make up for them?"

Zhang Zhai really didn't know which nerve of Lao Liu was wrong.

Although he has made some achievements in scientific research, it seems to have nothing to do with his undergraduate and physics majors.

Even if you want him to go to class, it would be more appropriate to go to the School of Computer Science, right?

"If you are told to go, you can go, there is so much nonsense.

I don't care if you do well or not! Anyway, you have to do it for me! "Old Liu said stubbornly.

"Old Liu, peat, you are unreasonable! If I give you a substitute class, what benefits will you get!" Zhang Zhai was really speechless.

"I'm not good, but am I giving you a chance?" Lao Liu glanced at him and said.

"Opportunity? What opportunity?"

"Don't worry about it so much! If you want the credits of number theory this semester, don't try to refuse!" Lao Liu threatened.

The one who taught Zhang Zhai's number theory was Lao Liu's student.

"You are using power for personal gain! Threatening students, I will report you to the dean!" Zhang Zhai said angrily.

"Go, the dean of the School of Physics is my classmate."

"..."

"Hey, you kid, you still want to fight with me, be tender, get ready, tomorrow morning from ten to twelve, if you screw me up, hey..."

Lao Liu put down these words and left.

Zhang Zhai was left alone in the library.

To be honest, can Lao Liu threaten Zhang Zhai with these threats?

Certainly not.

But why did Zhang Di give in?

It's not because of the favor owed to Lao Liu.

Although Lao Liu's operation, he was forced to substitute for him, which made him confused.

But he still believed that Old Liu couldn't be fooling around.

"Hey... well... I'm just a miserable person. I don't have a life of good fortune, so I can't be free even if I want to!" Zhang Zhai climbed up from the chair helplessly.

Start in this library and find a book.

"Where are the books on quantum mechanics?" Zhang Zhai asked the staff.

Unexpectedly, the staff member glanced at him and said, "You are Zhang Zhai, right?"

"Um, I am." Zhang Zhai was a little confused, so could it be that this person is also his fan.

"Oh, Professor Liu asked me to hand it over to you." After confirming Zhang Zhai's identity, the staff turned around and picked up a stack of books from his feet with difficulty.

Zhang Zhai looked at the stack of books that were over his head when he picked them up, and smiled helplessly, "Old Liu, dammit, you really have it!"

Zhang Zhai took the stack of books and gritted his teeth with some difficulty.

More than a dozen big books, big and small, it is absolutely no problem to be a brick.

""Fundamentals of Quantum Mechanics", "Feynman Lectures on Physics", "History of Quantum Mechanics", "Advanced Quantum Mechanics", Dirac's "Quantum Mechanics", "Non-relativistic Quantum Mechanics"... really respect me." Zhang Zhai gritted his teeth.

Holding these books, Zhang Zhai wanted to cry but had no tears.

What is quantum mechanics?

Feynman said: Anyone who says he understands quantum mechanics is lying!

Although this sentence is exaggerated, quantum mechanics itself is something that gets more and more confused the more you learn it.

Fortunately, Zhang Zhai still has a little foundation in mathematics, such as advanced algebra, linear algebra, number theory, partial differential equations, etc. Zhang Zhai still knows a little bit.

It's not that when reading books on quantum mechanics, you can't even understand the formulas.

...

Zhang Zhai was forced to go to Liangshan by Lao Liu. If he didn't want to make a fool of himself tomorrow, he would have to roll up his sleeves and work hard today.

Hope time will come.

Zhang Zhai started with "Feynman Lectures on Physics" and basic quantum mechanics, so that he could gradually understand.

Although his comprehension ability and logical ability are far superior to ordinary people, it is impossible for him to learn advanced quantum mechanics without a little foundation.

Zhang Zhai turned to the first page of the book and began to concentrate, try his best to understand and absorb the knowledge in the book.

This time, Zhang Zhai's speed is not very fast. Compared with the previous research on artificial intelligence, the reading speed is extremely slow.

The reason is very simple. The previous learning of artificial intelligence related knowledge is more about the verification and absorption of the artificial intelligence knowledge that already exists in the brain and is rewarded by the system.

But now, it is different, Zhang Zhai has never been exposed to quantum mechanics before, and has no experience.

In the previous college courses, the classical mechanics and the current quantum mechanics are completely different. Therefore, Zhang Zhai has no experience to follow. In the field of quantum physics and quantum mechanics, he is a blank slate.

If you want to speed up, you can't get up.

The first basic quantum mechanics, it took him nearly two hours to finish the book.

What slowed him down was the complicated calculations.

Only then did he discover that his mathematical knowledge was so shallow that it was a complete obstacle to his current study of quantum mechanics.

"Huh... Quantum Mechanics, it's really interesting!" Zhang Zhai closed the book and let out a sigh of relief, but his head didn't stop calculating. He was still immersed in some formulas of Quantum Mechanics.

Maybe it's because of his super high intelligence index. After reading this book, he felt very surprised. He was amazed by the magic of the world of quantum mechanics, and he felt very amazing.

This kind of wonder made him happy, comfortable and enjoyable.

The quantum world is really intoxicating and amazing. It is completely different from the macro world.

There are even some laws that contradict each other and conflict with each other in the macroscopic world and the quantum world.

But... why?

Obviously they are in the same world, the quantum world and the macro world, why some laws are contradictory.

Isn't this scientific?

Zhang Di had doubts in his heart, which gave him the motivation to continue studying.

Otherwise, if it is just a substitute class, after reading this book on basic mechanics and adding this book on the development history of quantum mechanics, it will be more than enough for tomorrow's class, and there is no need to continue at all.

Zhang Zhai pursued the question in his heart, and began to try to find the answer in the book.

But can he find the answer in the book?

The answer is definitely no,

He couldn't find the most accurate answer because...

There have been countless physicists, divided into two factions, who have quarreled.

There are also physicists who try to unify classical mechanics and quantum mechanics in the same framework.

But they all undoubtedly failed.

Some people insist on the correctness of classical mechanics, while others think that classical mechanics is wrong. The contradiction between it and quantum mechanics proves this point.

But what exactly?

To be honest, this chapter confuses me.

In addition, recommend a friend's novel, "Looking for Pets in the World", it is said that the author is a cute girl? Can you tease me?
