I failed a course, and the system became my study supervisor.

Chapter 10 Reveal to me the secret of the magnet, the secret second only to love and hate

It was almost eight o'clock in the morning when Xu Ling hurried to the classroom. Teacher Zhang had not arrived yet, but the classroom was already full.

After looking around for a long time, Xu Ling finally found a seat. Just as he squeezed in, the girl who showed him the seat said in surprise:
"Eh? It's you!"

"Huh? Who are you?" Xu Ling was also a little surprised and looked at the girl with a puzzled look.

The more he looked at it, the more familiar it seemed, but Xu Ling couldn't remember it for a moment.

The girl's face flushed instantly, and she gritted her teeth and said, "You don't even remember me? The library! Do you remember?"

"Oh, I remember now! But aren't you a junior? Why are you taking this course?"

Xu Ling finally reacted, but the doubts in his heart remained.

"I changed my major in my sophomore year and haven't taken this course yet." The girl looked much better and answered softly.

Xu Ling suddenly realized, let out a long "oh" and stopped talking.

Xu Ling remained silent, but the girl's heart was boiling with anger.

Hey! We've already met twice! We've talked so much, and you didn't even ask my name?

"My name is Lin! Yu! Xin!" the girl said word by word.

Now it was Xu Ling's turn to be puzzled.

What did I say again? Why do I act like I'm angry again?

But since he had introduced himself, he couldn't help but speak. Xu Ling quickly spoke, imitating Lin Yuxin's tone:

"My name is Xu! Ling!"

Hearing this answer, Lin Yuxin was completely stunned.

This person might have some serious illness!
Just when the two were in a stalemate, the sound of leather shoes stepping on the ground came from outside the classroom door, and the noisy classroom suddenly became quiet.

Professor Zhang Zhongyao is here!
Everyone's attention was instantly focused on the little old man who was slowly walking towards the podium.

Professor Zhang Zhongyao is very thin, not tall, and has a dark skin, but he stands straight and his eyes seem to be glowing.

The old suit and slightly baggy pants on his body easily remind people of the comedy master Charlie Chaplin.

"Chaplin" walked up to the podium, stood still, and without saying a word, bent down and bowed.

There was instant applause from the audience.

When the applause died down, Professor Zhang cleared his throat and spoke slowly:
"Hello everyone! I'm Zhang Zhongyao, and I'm in charge of your electromagnetics course this semester. I hope everyone can benefit from my class."

He gave a brief self-introduction without bragging about his achievements, but the audience still broke into thunderous applause.

Zhang Zhongyao stretched out his hand and pressed it in the air, signaling that the class should begin.

"Please reveal to me the secret of the magnet, the secret second only to love and hate!" This is a line from Goethe's poem. It reflects people's understanding of magnetic phenomena at that time. People discovered that magnets can attract each other, which is very similar to human love, and gave the magnet a poetic name - lovestone.

……

Human beings' real theoretical research on magnetism came later than that on electricity. This is because although the study of magnetism has similarities with electricity, it is more complicated.

……

People have been exploring magnetic monopoles for a long time, but there has never been any precise experiment to prove their existence.

......"

Zhang Zhongyao spoke eloquently throughout the entire class, from the history of the development of electromagnetism, to the applications of electromagnetism, to the ongoing scientific exploration, leaving all the students in the audience wanting more.

Is this electromagnetism? Its theoretical world is so vast and poetic!

If someone asks Xu Ling what the ultimate romance is, he will answer without hesitation: electromagnetism!

The silence in the classroom was finally broken, and warm applause was once again given to Zhang Zhongyao's classroom.

Xu Ling also came back to his senses, and his gaze inadvertently turned to the seat of his deskmate.

I rely on!

Xu Ling was shocked!

Lin Yuxin's head was almost buried in the desk, and she could even hear faint snoring. She had actually fallen asleep! The applause from the classroom didn't even wake her up.

How could she sleep?
Teacher Zhang’s course is so wonderful!
What shocked Xu Ling even more was that when the bell rang, Lin Yuxin, who had just been in close contact with the table, immediately raised her head and her expression became clear again, as if the unconscious person just now was not her.

"What's wrong?" Looking at Xu Ling's strange expression, Lin Yuxin asked puzzledly.

"Nothing, nothing." Xu Ling shook his head repeatedly.

Lin Yuxin looked at Xu Ling scrutinizingly, but didn't say much. She took the initiative to add Xu Ling's Penguin account and left the classroom.

The students in the classroom left one after another, and only a few students stayed and found Zhang Zhongyao to ask questions.

Xu Ling naturally didn't rush to leave. He stood next to the student who asked questions and listened to his questions and Teacher Zhang's answers.

"Student? Do you have any questions?"

Hearing the voice, Xu Ling came back to his senses and found that only Zhang Zhongyao was left in front of him.

Xu Ling quickly asked his own question: "Hello, Professor Zhang. Earlier in class, you mentioned people's exploration of magnetic monopoles. My question is, after spending so much time and still not finding conclusive evidence, why do people still believe that they exist?"

Zhang Zhongyao was a little surprised. He didn't expect Xu Ling to ask this question. He looked at him deeply and said in a deep voice:

"The universe is a world full of symmetrical beauty."

After saying that, Zhang Zhongyao didn't say anything else. He left Xu Ling in a daze and walked away.

Symmetrical beauty?
Do academic giants also like to be riddlers?

Xu Ling complained inwardly.

Without paying too much attention, Xu Ling rushed to the next classroom because he had another class in the morning, which was linear algebra taught by Teacher Zhang Yongjie.

It was not until the end of the class that Xu Ling realized that the evaluation of Teacher Zhang in the course review community was still too conservative.

Too much homework? It's a ton! What good teacher assigns ten problems in the first class?
Do you like to talk about things beyond the syllabus? That’s simply not teaching the content in the textbook!

He often said one sentence in class:

"You should know this, so let's take a look at another interesting thing."

This kind of class pace made many students complain, and even Xu Ling, who was a bit of a stunner, found it difficult to keep up.

After finishing the morning class, Xu Ling was already starving. He quickly rushed to the cafeteria, but once again saw a scene that made him tired.

Why are there so many people!

But Xu Ling was so hungry that he had to grit his teeth and queue up.

While waiting in line, Xu Ling opened the system panel. Looking at the task panel that had not been refreshed for a long time, Xu Ling felt helpless.

The supplementary exam results haven't come out yet, and I don't know how long the series of tasks will take, and I only have 10 motivation points.

After classes every day, I can’t get the library check-in task, and there is no incentive to study harder.

The days without task refreshes are so hard!
