Zhou Yi, who had a good rest for a day in the media's praise, returned to the team the next day, trained with the main force, and officially started preparations for the Ruhr District derby.

Although the preparation time is a little short, it is very familiar because it is an old opponent in Derby and does not take too much time to understand the opponent.

And there is no need to make any major adjustments. Klopp's tactical thinking has always been "self-oriented". That is, Dortmund insists on playing his own tactics, and does not need to make various adjustments due to different opponents. In this way, it will actually disrupt your pace and rhythm.

The training is still arranged normally. It may not be obvious from the training content alone that the derby is approaching. However, by looking at the media, you can immediately smell the upcoming smoke of the Ruhr derby.

Supporters of both sides have been fighting verbal in the media and support their own team.

Even the two teams get players.

Groschloitz is a player who came out of the South Stand. If he doesn't act as a player, he will definitely be a fanatical supporter of Dortmund. So every time there is a Ruhr derby, he always rushes to the top two years ago.

This time he laughed at the Derby opponent in an interview.

"Neul said he was ready? Of course they were ready. In order to prepare for the game against us, they even lost the mid-week Champions League group stage!" At this point, Groschloitz shrugged and smiled badly.

In the Champions League group stage a few days ago, Dortmund and Schalke 04 both played away. Dortmund defeated Valencia 2-0 away, while Schalke 04 lost to Lyon 0-1 away.

As a mortal enemy in the city, I naturally would love to see another team in trouble.

Moreover, Groskreuz's move was to sprinkle salt on Schalke 04's wound. If he lost the ball, Schalke 04 fans were very upset. They would be laughed at by their mortal enemies in the city. Who can tolerate it?

Schalke 04's striker Falfan stood up and hit back at Groskreuz: "Groskreuz's best prayer for his team not to lose in the Champions League."

If you lose the game, I will laugh at you.

The two sides started a war of words back and forth.

As the core of Dortmund, Zhou Yi is naturally the focus of everyone's attention. The topic of Derby cannot be avoided.

Although Zhou Yi only participated in one Ruhr derby, he is also a person who is not popular with Schalke 04 fans.

It's not just because he helped Dortmund beat Schalke 04 away last season, but also because of the penalty he won for Dortmund in the last matchup.

Schalke 04 supporters insist that Zhou Yi used a despicable fake fall to trick the penalty kick. This penalty kick is crucial.

So the reason why Dortmund was able to win that game was because of Zhou Yi's disgraceful method.

Before this competition, the media brought up the old story again.

"Fake a fall?" Zhou Yi opened his eyes wide. Then he made a serious expression of thinking, and finally he shook his head and said, "Is there any? I don't remember."

"That penalty..." the reporter reminded him.

"Of course it's not a fake fall." Zhou Yi answered very firmly. "Bordong knocked me down and I fell down. Is there anything wrong with this?"

"That's it, but don't you think your actions after falling are a bit exaggerated?" asked the reporter, who was obviously from Schalke.

"Are you saying I turned around a few rounds? Oh. Sorry, I'm not trying to gain sympathy. I'm doing this just to protect myself. This is called unloading force." Zhou Yi said. "This is a physical phenomenon. It is a natural law. If I fall to the ground without rolling a few rounds, I will not be able to transmit the impact force to the ground well. This will cause great harm to myself."

The reporter obviously thought that Zhou Yi was making excuses. The latter said that he believed that Zhou Yi had fallen in his heart, so he naturally would not accept his explanation. So he continued to ask: "Even for the purpose of protecting himself, you don't have to go through so many circles, right?"

A Chinese reporter next to him was dissatisfied with the Schalke reporter's question and protested: "You are asking a question with a preset premise and position..."

The German journalist turned around and looked at the protesting Chinese journalist arrogantly, then turned around and ignored it.

This made Chinese journalists very upset and started to shout.

Seeing that the gunpowder smell suddenly became stronger, Zhou Yi quickly raised his hand and said to the reporter of his motherland in Chinese: "It doesn't matter, let him ask, he is not afraid of slanting his shadow."

Seeing Zhou Yi say this, Chinese journalists can't say anything. They just think that Zhou Yi doesn't need to be so polite to a Schalke reporter who deliberately comes to find fault. You are polite, but others don't. You can do this when dealing with gentlemen. If you deal with enemies, just go to the hunting rifle directly.

But Zhou Yi doesn't care. They can't help either.

I could only glar at the back of the German reporter. If my eyes could kill people, I'm afraid that the German reporter would have died countless times.

Zhou Yi looked at the reporter who was looking for trouble and said seriously: "It's inertia."

"Ah?" The German reporter didn't react.

Zhou Yi patiently explained: "Didn't you just ask me why I had to turn several times? I tell you that this is the cause of inertia. First of all, you need to know what inertia is. Inertia is a characteristic of an object when it remains stationary or is moving in a uniformly velocity. Inertia is an inherent property of an object. It is manifested as an impedance of an object to its movement state. When the external force acting on the object is zero, inertia is manifested as the object maintains its movement state unchanged, that is, it remains stationary, or moves in a uniformly velocity linearly. When the external force acting on the object is not zero, inertia is manifested as the difficulty of external force changing the movement state of the object..."

When the German reporter who asked the question was already confused when he heard Zhou Yi say this.

Zhou Yi had not stopped yet and continued to talk: "...Back to the question of why I roll more circles. According to the definition of inertia I just mentioned - the qualitative definition of inertia is the nature of an object resisting change in momentum, and quantitatively extending this definition to a measure of the object's resistance to change in momentum, it can be used to do mathematical calculations. This momentum becomes the mass of an inertia, referred to as mass. Therefore, mass represents the mass of an object, and at the same time, mass is also a measure of the inertia of an object..."

Speaking of this, Zhou Yi took the small notebook and pen in the hands of the reporter who asked the question.

The reporter was completely stunned and had no response to Zhou Yi's actions.

Zhou Yi, who had taken the notebook and pen, started writing and drawing in the reporter's interview book, and wrote it again and said: "The momentum equation expresses the relationship between momentum and mass and velocity of an object. If we express momentum as p. Mass as m and velocity as v, the relationship between the three is p=mv. However, Newton's second law equation can also express the relationship between the action force f and mass-inertial mass-m, and acceleration A: f=mA."

Zhou Yi really wrote these two equations in his notebook.

"According to such an equation, we can see that. If a force f is given, the larger the mass m, the smaller the acceleration A. Conversely, the smaller the mass m, the larger the acceleration A will naturally be. My mass is relatively small. When the force given by Borton is large enough, the acceleration A will be larger. The acceleration A will be larger. The acceleration is larger, and the more laps I will roll on the ground. If I had just arrived at Dortmund youth training camp for a year and a half, I might have turned more than four laps, six laps. Because at that time I was lighter, smaller in mass, and larger in acceleration."

Zhou Yi looked at the petrified reporter and finally said, "You ask me why I went around in such a circle? This is the reason. Do you have any questions?"

During Zhou Yi's explanation, a depressed laughter sounded behind the reporter. Now everyone's emotions could no longer be suppressed, and they burst into laughter.

Amid everyone's happy smiles, the Schalke's reporter also reacted that he was fooled by Zhou Yi!

He was so angry that he didn't even care about the so-called demeanor. He snatched the notebook from Zhou Yi, and then roared: "You are making a point of reason..."

"How is this arguing? I'm science." Zhou Yi looked at him with a smile and said calmly, "Mr. Reporter, are you questioning science? Questioning Newton's second law?"

Chinese journalists and Dortmund's reporters laughed so hard that they were almost breathless.

The reporter who was looking for trouble turned red, but couldn't say a word. He could only look down at the notebook in his hand. There were two formulas written on it, and the meaning represented by each letter was also represented by the formula.

Although he couldn't quite understand, every word on it seemed to be flashing with golden light, mocking him for his low IQ...

※※※

That night, Zhou Yi and the Schalke reporter had a confrontation on the TV station. On the Internet, not only were there pictures and the truth, but this time there were videos and the truth.

On youtube, Zhou Yi used Newton's Second Law equation to explain to Schalke reporter why he flipped four times in a row before stopping after landing. Since the number of clicks has increased rapidly since it was uploaded, and it soon became a popular video.

Because Zhou Yi confronted the reporter in German. The author of this video also thoughtfully attached English subtitles, so that most people can understand what they are saying.

Netizens enthusiastically left messages and praised Zhou Yi's performance.

"...This is so funny! For the first time in my life, I saw a professional player using Newton's Second Law equation to explain his performance on the court to reporters!"

"Puff! Zhou Yi did a pretty job! He had to do this for such a reporter who came to find fault!"

"Did you see the expression of that reporter? I'm sure he definitely didn't understand every word Zhou Yi said!"

"Hey man, stop talking about that reporter. To be honest, I know every letter on the subtitles, but ******* can't understand the meaning..."

"Zhou Yi is a Chinese player, and as far as I know, Chinese people are very smart. They often win the international math competition! All Chinese people are geniuses!"

"There are so high requirements for professional players now? Do you need to understand Newton's law?"

...

At the same time, almost the same video also appeared on the Internet in China, except that the English subtitles in the video were replaced with Chinese subtitles.

It also attracted everyone's popularity.

"Bring glory to the country! Hahahaha!"

"Zhou Yi is awesome!"

"Players know science, so I ask if you are afraid, haha!"

"What made Zhou Yi fall to the ground suddenly? What made Schalke 04 players siege the referee crazy? What made Magath roar? Is there an ulterior motive behind Dortmund's victory? Is Borton the culprit of Schalke 04's loss or was wronged? Why did the referee insist that this was a penalty kick? Is Zhou Yi's four rounds in a row exaggerated acting or a natural law? Behind all this, is the decline of the players' sports morality or the distortion of human nature? Please pay attention to the annual award of Science and Education Channel's 8 o'clock annual award "The Secret of Science: The Secret of Penalty" at 8 o'clock in the evening, let us follow the camera into the football world of the top scholar Zhou Yi..."

"Ah haha, please give me the psychological shadow area of ​​this reporter!"

"I really deserve to take the college entrance examination if I don't play football. This physics knowledge is really something I can tell you... If Zhou Yi is willing to study hard, it would be a problem to get into a key university, right?"

"What does it mean to be reasonable and well-founded? This is called reasonable and well-founded! Whoever dares to question it is to be unable to get along with Newton's second law!"

"No, so, isn't the fake falls at Lamacia Film and Television Academy true and credible?"

"On the upper floor, you should pay attention to the prerequisites. With constant force, the acceleration is inversely proportional to the player's mass. The bigger the player's weight, the fewer the number of laps on the ground. A tall and big man like Professor Bu is too exaggerated to turn six laps on the ground, so it's fake. You must know that Zhou Yi's weight is much lighter than him. He was hit by such a strong force by Bordong and rolled four laps..."

"Damn it, you have to understand physics when watching a ball. I feel so tired..."

There is a carnival among netizens on the Internet. In the official media, this Schalke reporter was also ridiculed and was ruthlessly crushed by Zhou Yi in terms of IQ...

Some media interviewed a physics professor in the university. The professor said that Zhou Yi was indeed not talking nonsense, and he was right.

"...In fact, all the activities of our humans on the earth cannot be separated from physics. Some phenomena are more complicated to explain by theory, but they are actually very common... For example, the fallen leaf ball is the embodiment of fluid mechanics in football..."

The professor wanted to talk endlessly to explain the Magnus effect to everyone, but the director cut the picture...

When I cut back, it was the professor's evaluation of this matter: "It was the first time that a player himself used physics knowledge to explain phenomena on the court. Zhou Yi's intelligence surprised me. I believe that even if he doesn't play football, he might be able to achieve some achievements in the physics road..."
Chapter completed!
