I'm a genius star

Chapter 556 Apprenticeship
Li, who was sitting in the first row, was staring at the blackboard all the time, the expression of struggle on his face was constantly changing, and he seemed to have experienced countless repeated struggles in his heart, and finally had to compromise with the result.

Su Yun's algorithm is correct, and every step has enough scientific basis to support his algorithm, and it is impossible for people to refute it.

However, this is not the end, Su Yun continued: "Now that we have figured out the most fundamental process of this problem, then we can start to calculate its specific cycle."

"As we said before, two simple harmonic motions can actually be synthesized into a uniform circular motion, then we can use the cycle of uniform circular motion to find the cycle of our problem."

没有等苏云说，台下的那位李同学就率先说道：“匀速圆周运动的周期T=2π√m/k，而k正好就是4/3πρGm，代入面的公式就可以得到T=2π√(3/4πρG)。”

After what Li said, the people around him also started to pick up their pens and start counting.

It can be said that as expected of the students of Peking University, most of them calculated the result within a minute, but after they calculated the result, they all opened their mouths in surprise.

Su Yun looked at them and smiled slightly: "That's right, you should have discovered that this cycle has nothing to do with the quality of people, it is only related to two factors, one is the density ρ of the earth, and One is the number G of the gravitational field, so we don’t need to find this period, it is a fixed value in itself!”

"That is to say, if you make a hole in the earth and jump in from one side, you will just exit from the other side, and the time of this process is certain. I have already worked out it for you. The time T is about: 5077 seconds, or about 84 minutes."

At this time, not only the seats in the classroom, but also the surrounding corridors and doorways were crowded with crowds of onlookers, but the scene was surprisingly quiet.

Some students from the physics department in front were okay, they took their pens and calculated it over and over again, which was surprisingly interesting.

However, for some people who are not in the physics department behind and outside, it is like listening to heavenly scriptures.

Punch a hole through the earth, jump in from one side, and the hell can just come out from the other side?I won’t talk about being able to go out, the time is still fixed?Only 84 minutes?

What is this all about! ?
The old professors in the back row were dumbfounded, but they didn't know what to say.

Because Su Yun's solution is indeed correct, every step is supported by sufficient scientific evidence, and there is nothing wrong with the calculated result, but if they really want to tell them, they always feel that there is something weird.

"Pfft..." Li, who was sitting in the first row, suddenly smiled. He didn't care about other people's eyes. He looked at Su Yun and said, "Su Yun. No, Dr. Su, you are a real genius. You are my fault, sorry."

As he spoke, he suddenly stood up from his seat, and then bowed deeply to Su Yun.

Su Yun also smiled, shook his head and replied: "I don't think you should say this to me, but to your teacher. After all, the teacher of this class is not me, but the teacher behind you." bit."

Classmate Li was slightly startled, walked behind without the slightest hesitation, bowed to the young female teacher, and said, "I'm sorry, teacher, I was wrong before, please forgive me."

Su Yun pulled Tu Su out of the classroom, and many students cheered and applauded from behind.

In fact, Su Yun doesn't dislike students like classmate Li at all. Relatively, he may like this kind of thing more than ordinary students.

Compared with those who just do and solve problems blindly, he prefers the kind of students who can go around in circles to think wildly and constantly think about new problems.

Just like the problem of the earth piercing a hole, it is actually very suitable to be applied to high school physics problems. Not only will it not lack interest, but the knowledge points involved can deepen the impression of every student.

Of all the knowledge points that Su Yun mentioned before, is there any one that is difficult?

Actually not.

All the knowledge points he just mentioned can actually be found in the textbooks of physics books.

But it was just such a question, but the teacher present couldn't answer it for the students. Is this really a student's problem?
Just when Su Yun was thinking about these things, a person ran up behind him, still calling his name.

"Doctor Su, wait a minute!"

Su Yun stopped in his tracks, turned around and saw that the person who was chasing him was none other than that student Li from before.

"Dr. Su, hehe...wait...wait a minute!"

The young man who ran from a distance finally ran in front of them, his panting hands resting on his knees, his slender body looked like he was not very good at sports.

He raised his head with some difficulty, and a few beads of sweat the size of rice grains slid down his cheeks on his forehead.It's hard to imagine, Su Yun and the others were only less than 100 meters away, how could he be so tired after such a distance.

"Dr. Su Su, please wait a moment."

Su Yun looked at him curiously, and asked, "What's wrong, do you have any questions?"

However, the young man just shook his head, took a long breath, and said, "Dr. Su, please accept me as an apprentice!"

Take me as an apprentice.
I'm a disciple
Be an apprentice.
Su Yun looked at the boy in surprise, and couldn't help but draw three black lines on his forehead.

It was the first time he heard someone say that he accepted me as an apprentice in the real world. It was a bit unreal, and he asked in a daze: "Um, that classmate Li, what did you just say, can you say it again?" one more time?"

Student Li looked at Su Yun firmly, and repeated again: "Please accept me as an apprentice!"

Su Yun wiped the sweat that didn't exist on his forehead, and replied speechlessly: "Well, classmate Li, I don't accept apprentices, so you can find another expert."

However, he still did not give up and said, "If you accept me as an apprentice, no matter if it is money or anything else, as long as you say it, I will definitely satisfy you!"

Su Yun was a little speechless, and replied: "Little boy, how old are you, don't be like adults, who want to use money to solve everything you learn, not to mention, do you think I am short of money?"

Su Yun turned his head and glanced at Tu Su, secretly thinking: Even if I am short of money, young master, with my wife here, can I still be short of money? !

Tu Su turned her head and looked at him, not knowing if she understood what was going on in his heart, but just smiled at him.

Student Li was a little confused when he heard this.

On weekdays, no matter who he asks for help, as long as he gives more money, most things can be solved, but it doesn't seem to have any effect on Su Yun.

I heard that he made more than one billion yuan a month from stock trading. This rumor should be true, so he must not be short of money. If so, what should we do?
For the first time in his life, student Li fell into deep thought.
