I am reborn and just want to concentrate on my studies

Physics class.

The further we go, the more we realize that the physics teacher Wu Ming is a very talented person. His class progress is frighteningly fast. There is not much time left for the midterm exam, but her class progress has already reached Chapter 6 "Mass and Density" ". Although the course is fast, the knowledge acquired by the students is very solid. At the same time, what he talks about often exceeds the syllabus, but because it goes beyond the syllabus, it arouses students' interest... which is outrageous.

"The quality of today's talk is actually about this much content. Because everyone has come here for preview, there are only so many things that need to be mastered in class. In the last ten minutes, as usual, I will tell you a little more about what is beyond the outline. content……"

Upon hearing this, some girls sighed slightly, and Yi Yang noticed that Ning Zhixin, who was sitting not far away, was also sighing... Probably because every time Wu Ming talked about super-comprehensive things, he couldn't understand them. …

Luo Luoyue showed some excitement. She said: "People who have a talent for learning physics will definitely fall in love with physics if they listen to Teacher Wu's class."

Yi Yang nodded, agreeing with this. The things Wu Ming talks about that are beyond the general scope are very good at cultivating students' interest in physics.

"When it comes to quality, everyone first uses the standard of weight to feel it. So how much does it weigh? Ten tons, one hundred thousand tons, one billion tons? What will happen if it weighs to a certain extent?"

"This is related to the general theory of relativity. We have already learned about universal gravitation, but there are still problems with universal gravitation. This problem is action at a distance. Is there a need for a medium for the propagation of gravity?"

"When people are pulling something, they need a medium, such as pulling a yo-yo, and there must be a string in the middle. In fact, any force exerted on another thing in our daily life requires a medium to transmit the force. , so have you ever thought about the fact that gravity is invisible and intangible, and the sun pulls our earth with gravity, does there need to be something between the earth and the sun to transmit this gravity?"

This passage seemed to be understood and everyone was thinking about it.

"Need, space?"

"Hmm...is there something we humans can't see?"

Some teenagers answered their own questions. Although it was very naive, Wu Ming was very satisfied.

Because I thought about it.

Yi Yang listened patiently. He really liked Wu Ming's style of talking about things in simple terms and explaining some high-level physical principles in the most popular terms...or rather his ability.

He probably really understands physics. A person who doesn't understand physics that well may not be able to do this.

Wu Ming smiled slightly: "Currently, our science cannot find a medium for gravity transmission. Therefore, this problem once troubled many scientists... Well, I think it also troubled you. Look, you and those great physicists Scientists are on the same page.”

There was a lot of laughter.

Wu Ming continued: "Einstein, the Einstein we are familiar with answered this question. The answer lies in his general theory of relativity. It believes that gravity is not a force. Gravity is the state of motion of an object in distorted space and time that deviates from a uniform straight line. The effect of exercise.”

"In other words, Einstein believed that gravity results from the distortion of time and space by mass."

The content suddenly became fantasy, and everyone showed surprised expressions.

At this time, the bell rang, and Wu Ming smiled slightly. He did not expect to be able to teach everyone the general theory of relativity in such a short period of less than ten minutes. To put it a little selfishly, I just hope to plant a seed in the minds of those children who are really interested in physics and are willing to explore physics and find answers. That is enough.

Every time I talk about these things, I can gain a little bit.

That's it.

…

During class, Ning Zhixin came over and asked Yi Yang coyly: "What you said this morning...does it still count?"

Yi Yang's eyes lit up and he said, "Do you agree?"

"Well... let me try."

Yi Yang rarely showed an excited expression. But there are still some doubts. Ning Zhixin is a very shy person, so she doesn't actually have much confidence in recruiting her. So she said she should think about it and basically gave up hope.

An unexpected surprise, an unexpected surprise.

After thinking about it, Yi Yang couldn't help but ask: "Why are you willing all of a sudden?"

"Huh? No, it's not sudden."

"Isn't it sudden?"

"Actually... I had this idea a long time ago, hey..."

"Yeah?"

"So, when will we practice?"

Yi Yang thought for a while and shouted to the fat man not far away: "Zhang Bushou, come here."

Zhang Bushou came over and the three of them stood on the edge of the balcony.

"Introducing Zhang Bushou, his other identity, our drummer."

Ning Zhixin showed an unexpected expression, "Drummer?"

Zhang Bushou said seriously: "Yes, the drummer's hands are also palms, commonly known as applause. What I am best at is retreating..."

Ning Zhixin was stunned, covered her mouth and smiled, then asked Yi Yang, "You...are you the lead singer?"

Yi Yang nodded: "Leader and guitarist."

"Is there anyone else?"

"It's gone now."

Ning Zhixin thought for a while: "Three people...well, that's okay. There is a keyboard anyway...but I don't know how to do it."

"It's okay, there is a teacher to teach you."

"You also invited a teacher?"

"Free, an angel."

Zhang Bushou thought for a moment and said, "It's an angel, it's an angel."

"Angel?" Ning Zhixin laughed. The strange words were probably humorous.

"Then it's settled. Today happens to be Friday. Let's go there together after school."

"Okay~"

…

"This is Ning Zhixin from our class. She can play the piano." Yi Yang said.

Jiang Lili nodded, "Come in first."

Naturally, Yi Yang walked into Jiang Lili's house in a familiar manner and sat down on the sofa. Zhang Bushou was careless and Yi Yang followed his example and sat down on the sofa. But Ning Zhixin was very restrained, standing there with uncertain eyes.

Jiang Lili brought a fruit plate and invited Ning Zhixin to sit down. Afterwards, he and Yi Yang chatted for a few words, and they seemed like relatives.

Ning Zhixin couldn't help but feel weird when she saw it, thinking to herself, could Teacher Jiang be Yi Yang's...sister?

Is she an angel?

Zhang Bushou may be stupid, but he is also imitating this. His brother's sister is his sister. She has only been here once and she behaves very familiar with her.

Ning Zhixin seemed restless in such an unfamiliar environment. Fortunately, Jiang Lili soon turned her attention and chatted for a few words. Ning Zhixin fell in love with this music teacher who was gentle and gentle during class. . Jiang Lili smiled and asked, "How many years have you been studying piano?"

Ning Zhixin said with some embarrassment: "Well... it didn't take long. When I was a kid, I was taken to practice by my mother to get extra points... I probably passed level 10 when I was 11 years old, but I haven't made any progress for a long time. Now every day I just practice the music I learned before taking the exam..."

Zhang Bushou said in surprise: "Wow! Level ten!"

"No...Level 10 is almost the entry level, or not even entry level." Ning Zhixin said shyly.

"No, for music students, it's really meaningless to talk about grade examinations, but for non-majors, grade 10 is still very good." Jiang Lili said.

Yi Yang thought that level 10 was probably the level of Jiang Lili when she was 8 years old, she had said.

But enough.
