Chapter 57: Substitute?

Seeing Zhang Zhai a little hesitant, he promised, but did not expect, then, Zhang Zhai's face changed, "then ... let's forget it!"
"Then say that ... what?" Old Liu was about to breathe a sigh of relief, and suddenly reacted again, Zhang Zhai didn't seem to agree.
"Zhang Zhai! Isn't you a dumb kid that doesn't understand you! It's easy to say that I can't even help with this little help!" Lao Liu stared at the big eyes, patted the table, roared.
Zhang Zhai heard the words, and he was a bit embarrassed, but more helpless.
"Old Liu, is this a question I ca n’t help? If you say you want a holographic device, I'll get one for you. But you have to let me go to teach you! You are not forced Does the cow lay eggs? "
"Again! You are teaching quantum mechanics, a junior year. I ’m just a sophomore now. I know what quantum mechanics is ..." Zhang Zhai really wanted to cry without tears.
"Does the dean know that you are so arrogant? Old Liu, so many professors, you can just let them finish the lesson for you, it's really impossible, you just come back and supplement them?"
Zhang Zhang really didn't know, which old Liu's nerve was wrong.
Although he has made some achievements in scientific research, it seems that he has nothing to do with his undergraduate and physics majors.
Even if he was going to take a class, would it be more appropriate to go to computer school?
"I'll let you go, you'll go, there's so much nonsense.
I care if you go well, not go well! You have to go get me anyway! "Old Liu said stubbornly.
"Lao Liu, peat, you are unreasonable! I will give you a substitute, what benefits can you get!" Zhang Zhai is really speechless.
"I'm not good, but am I not giving you a chance?" Old Liu glanced at him and said.
"Opportunity? What opportunity?"
"You don't care so much! If you want the credits of number theory this semester, don't think of rejecting!" Old Liu threatened.
Zhang Zhai teaches number theory, and is Liu's student.
"You are trying to gain personal gain by threatening power! Threatening students, I will report you to the dean!" Zhang Zhai said indignantly.
"Go, the dean of the School of Physics is my classmate."
"..."
"Hey, boy, you still want to fight with me, be tender, get ready, tomorrow from 10 am to 12 o'clock, if your kid messed up with me, hey ..."
Old Liu 撂 this sentence, and left.
I left Zhang Zhai alone in the library.
Honestly, can these threats to Lao Liu threaten Zhang Zhai?
I definitely can't.
But why did Zhang Zhai fall in love?
I still don't owe it to the old Liu.
Although the operation of Lao Liu, he had to force him to substitute for him, leaving him scratching his head.
But he still believes that old Liu can't be blind.
哎 "Hey ... gotta ... I'm a hard-working person. Without that blessed life, I can't just rest idle!" Zhang Zhai helplessly climbed up from his chair.
I began to find books in this library.
"Where is the book on quantum mechanics?" Zhang Zhai asked the staff.
Who knows, the staff glanced at him and said, "Are you Zhang Zhai?"
"Um, I am." Zhang Zhai is a bit unclear. So, is this also his own fan.
"Oh, this is what Professor Liu asked me to transfer to you." After confirming Zhang Zhai's identity, the staff turned around and took a stack of books from his feet.
Zhang Zhai looked at this uncle and hugged more books than his head, and smiled helplessly, "Old Liu, ah, I really have you!"
Zhang Zhangzhai took the book and bit his teeth hard.
Dozens of big books, thickness and size, there is absolutely no problem when a brick.
"" Basics of Quantum Mechanics "," Feynman's Lecture Notes "," History of Quantum Mechanics "," Advanced Quantum Mechanics "Dirac's" Quantum Mechanics "" Non-Relativistic Quantum Mechanics "... really worthy of me." Zhang Zhai gritted teeth.
I held these books, Zhang Zhai wanted to cry without tears.
What is quantum mechanics?
Feynman said: Whoever said that he knew quantum mechanics, he was lying!
Although this sentence is exaggerated, quantum mechanics itself is something that gets more and more confused.
Fortunately, Zhang Zhai still has some mathematical foundations, advanced algebra, linear algebra, number theory, partial differential equations, etc. Zhang Zhai still knows something.
I do n’t even understand formulas when I read books on quantum mechanics.
Uh ...
Zhang Zhai was regarded as being forced to Liangshan by the old Liu. If he doesn't want to be ugly tomorrow, then he can only do so and work hard to raise his sleeves and work hard.
I hope time is too late.
Zhang Zhai started with Feynman's Lecture Notes and basic quantum mechanics to help him gradually understand.
Although his ability to understand and logic is far beyond ordinary people, it is impossible for him to learn advanced quantum mechanics without any foundation.
Zhang Zhai turned to the first page of the book and began to concentrate, trying 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 was more about the verification and absorption of artificial intelligence knowledge that already exists in the brain and is systematically rewarded.
现在 Now, it's different. Zhang Zhai had no contact with excess submechanics before and had no experience.
In previous university courses, the classic mechanics and current quantum mechanics that were exposed were completely different. Therefore, Zhang Zhai had no experience to follow. In the field of quantum physics and quantum mechanics, he was Zhang Baizhi.
I do n’t think I can get up faster.
It took him nearly two hours to finish the first basic quantum mechanics.
What slows him down is the complicated operation.
He only found out that his mathematical knowledge was so shallow that it was a complete obstacle for him to learn quantum mechanics ~ EbookFREE.me ~.
呼 "Whoo ... quantum mechanics is really interesting!" Zhang Zhai closed the book and breathed out, but his head didn't stop computing. He was still immersed in some formulas of quantum mechanics.
Maybe it's his high intelligence index. After reading this book, he felt very surprised. Marveled at the magic of the world of quantum mechanics, it felt very wonderful.
This wonderfulness makes him feel like a lover, very comfortable and enjoyed.
The quantum world is really intoxicating and surprising, he and the macro world are completely different.
Even some laws contradict and conflict with each other in the macro and quantum worlds.
Hey ... but why is that?
Wu Mingming is in the same world. Why does the quantum world and the macro world contradict some laws?
This is not scientific?
Zhang Zhai had doubts in his heart, which gave him the motivation to continue learning.
Otherwise, if it is only a substitute course, after reading this basic mechanics, plus the history of the development of quantum mechanics, it will be more than enough to cope with tomorrow's course, and there is no need to continue.
Zhang Zhai pursued the doubts in her 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 were countless physicists, divided into two factions, and had quarrels.
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, and some people think that classical mechanics is wrong. The contradiction between him and quantum mechanics proves this.
But what exactly is going on?
