Lin Chen took it and turned it over carefully.

Ignore the prompts in front of you.

A lot of words in the book entered his mind.

Lin Chen’s theoretical foundation of quantum mechanics is improving rapidly!

……

After flipping through the entire book, Lin Chen closed the page with a confident expression.

Just now he was just a layman who knew nothing about quantum mechanics.

But now, Lin Chen has mastered all the theories of this book.

This book is actually not profound, it is just an introductory book on quantum mechanics. Of course, for ordinary people, it is equivalent to a heavenly book.

Zhuge Dali has been reading this kind of book since he was a child. No wonder he grew up to be a master of programming.

but.

He has been able to solve all Zhuge Dali's questions.

Immediately.

Lin Chen sat on the sofa and explained to Zhuge Dali attentively.

"Dali, regarding this, the coefficients of the superposition state in quantum mechanics are usually a complex number rather than a real number〃〃."

"The probability of obtaining each eigenstate in the measurement results must be a real number, so we have to redefine the inner product in the complex domain."

"To make the result of the inner product a real number, we have to rewrite its definition as the summation of the modular squares of the superposition coefficients, that is, each coefficient and its complex conjugate are multiplied and then summed term by term..."

[Teaching +1! 】

Zhuge Dali listened very carefully, nodding from time to time and asking questions from time to time.

"Lili, do you understand?"

Great Sage Zhuge was listening and felt that she understood every word Lin Chen said, but all together she couldn't understand a word.

It's like listening to a book from heaven, full of confusion.

Zhuge Dali nodded excitedly.

"Mom, Brother Lin Chen said it very well!"

“He first cited the example of Schrödinger’s cat, bringing out the most fundamental object of quantum mechanics, the state vector, and the Dirac symbol used to represent it.

Then, brother Lin Chen introduced me to the concepts of eigenstates and state spaces through the analogy of vectors on a two-dimensional plane, and explained the fundamental differences between quantum mechanics and classical mechanics through the value range of state vectors.

Now he explained to me the probabilistic meaning of the linear superposition coefficient of the state vector and related it to the inner product and orthogonality of linear algebra.

"After listening to Brother Lin Chen's talk about the various connections between physical phenomena and linear algebra concepts, I understand more and more how to use vectors to describe quantum states!"

"Also, brother Lin Chen's lectures are simple, vivid and interesting. I think his level is better than the gold medal teachers in our school!"

Zhuge Dali happily preached to her mother.

Great Sage Zhuge: "..."

Even more confused!

She didn't even understand a word Zhuge Dali said, but she kept her mother's wise smile. Although she didn't understand, she nodded pretending to understand.

"Then you have to learn from brother Lin Chen."

"Ok!"

Zhuge Dali agreed excitedly.

Hu Yifei opened her mouth wide and was a little shocked!

did not expect.

Lin Chen, a screenwriter, really understands such a profound theory as quantum mechanics? !

Immediately, Hu Yifei happily patted Lin Chen on the shoulder.

"It's so reliable!"

"I'll leave it to you next."

This time.

She can prepare for her PhD exam with peace of mind!

Hu Yifei walked into the room happily and began her preparation journey.

Talked all afternoon.

Lin Chen's mouth was a little dry, and he finally finished explaining all Zhuge Dali's confusion.

"Is there anything else you don't understand?"

Lin Chen asked.

"No, brother Lin Chen, you said it very well!"

Zhuge Dali looked at Lin Chen with admiration and said.

"If there's anything you don't understand, you can ask me again next time." Lin Chen smiled and returned the book to her.

Zhuge Dali took back her theoretical book as if he had found a treasure. She also took a lot of notes and felt that she had gained a lot.

"｀ ¨Thank you, Brother Lin Chen, you are the most knowledgeable person I know!"

Zhuge Dali smiled happily.

"Hey, Dali, you mean I'm uneducated?"

Hu Yifei appeared behind Zhuge Dali at some point, grabbed Zhuge Dali's face with a smile, and then pulled him to both sides.

Zhuge Dali's little face was elongated.

"Fu Laosi, Kuo is able to breathe and understand the light and interest (Teacher Hu, but you don't understand quantum mechanics)"

Zhuge Dali said vaguely.

"Lin Chen, thank you so much."

There was something wrong with the way Zhuge Dasheng looked at Lin Chen.

There seems to be something else added to the worship.

Originally, Great Sage Zhuge had to worry about how to lead Zhuge Dali every weekend.

As Zhuge Dali grew up, the questions he asked became more and more tricky (Zhao Lihao), and her image as a wise mother seemed to be in jeopardy.

I can only use a mysterious smile and a wise look in my eyes. I think this question is very simple, but it would be better for you to find the answer yourself.younger brother'

This trick fooled him too much, and Zhuge Dasheng felt that Dali's eyes were becoming more and more suspicious.

It seemed that she, as a mother, was not as smart as her daughter, and could no longer hide it.

This made the Great Sage Zhuge happy and distressed.

But today, Lin Chen simply saved her a lot of trouble.

She didn't expect that Lin Chen could talk to Zhuge Dali all afternoon!

This was the most relaxing weekend she had ever had!

Just watch TV on the side!

"If Lin Chen could be Lili's father, wouldn't it be much easier for me in the future? I can also go out with my little sisters to play, go shopping, and go shopping on weekends..."

The great sage Zhuge couldn't help but have such an idea in his mind.

Chapter 289 Dali likes brother Lin Chen very much

Great Sage Zhuge sighed.

Ever since she raised Zhuge Dali, she hasn't been able to go shopping freely and safely for a long time.

I really miss my old single life.

or.

It would be okay to get her a man to help take care of the children.

Great Sage Zhuge's eyes were quite full of resentment.

But no one noticed.

"Yifei, why did you come out again?" Lin Chen asked.

"Hey, I really can't carry it anymore. I'll come out and change my mind."

Hu Yifei pulled Zhuge Dali's face and was very happy.

To get a doctoral degree, you need to take ideological and political theory subjects, as well as a foreign language test.

Hu Yifei's head was so big that she felt like she had lost a lot of hair.

"Do you want to try this?"

Lin Chen mentioned.

He found a quick memory pill in the system mall.

After eating.

It can quickly improve the human body's memory within an hour and ensure efficient memory.

The price is also very cheap.

Just a little apartment value can be exchanged for ten.

Seeing how hard Hu Yifei was carrying, Lin Chen exchanged ten of them, took out one, put it in his hand, and handed it to Hu Yifei.

"what is this?"

Looking at the small red pill in Lin Chen's hand, Hu Yifei took it curiously.

"This pill can 727 quickly increase your memory within an hour."

Lin Chen smiled.

"Is it so magical?" Hu Yifei was stunned.

"Brother Lin Chen, it's best not to take medicine of unknown origin."

As soon as Zhuge Dali said something, Hu Yifei raised her head and swallowed it without hesitation.

"It's okay, can Lin Chen still hurt me?"

Hu Yifei said nonchalantly.

She shook her head.

Huh?

She suddenly felt that her brain seemed to become more flexible and her thinking became clearer.

What I memorized just now does not require any effort to recall, it can be recalled in a moment.

"I'll carry it right away!"

Hu Yifei quickly ran to the desk, opened the question book, read a page at a glance, then closed her eyes and recalled it.

She was pleasantly surprised to find that she could actually remember the things she had memorized just now!

"Lin Chen, your medicine is so effective!" Hu Yifei said in surprise.
