Chapter one hundred and sixty-eight mathematics, physics and chemistry together

There were four questions circled on the paper, and the difficulty was indeed greatly increased. One of the questions also involved the calculation of gravity, which is the movement of three planets around. Seeing this question type, Liu Lang thought of a book called "The Three-Body Problem" in his previous life.

Science fiction, yes, this question involves the "Three-Body Problem", what you will learn from this question

Knowledge has reached the stage of advanced physics. Of course, the calculation of the "three-body" is very complicated. Even if a physicist wants to really calculate it clearly, it is not easy. What this question requires is not to get an accurate answer.

, as long as the range of speed change is calculated, even then, it is very difficult.

Liu Lang had an advanced physics course when he was a freshman. Although this question was difficult, it was not too big for him. It only took him more than three minutes to figure out the answer. There were four answers.

This way, even he used half a piece of paper to write.

Another question is about the calculation of the internal stress mode of the alloy. This question may be more difficult for others than the "three-body" question, but for Liu Lang, it is simple. In terms of material mechanics, he solved it easily.

As for the other two questions, they are just complicated processes and nothing at all.

"Professor Lu, do you think what I wrote is correct?"

Five minutes later, Liu Lang finished writing and handed the answer to Liu Lang.

"Okay, okay, Liu Lang, you don't come to participate in the training tomorrow. It's a waste of money. I'll tell Lu Tianming soon that I'll transfer you to the youth group to participate in the training... You! It's a waste if you don't come to learn physics.

, if you come to study in my department, you will probably become a scientist like Einstein in the future, Liu Lang, would you consider it?"

Although he thought it was impossible, Lu Hua still wanted to try to dig into the mechanical department.

"Haha, thank you Professor Lu. I still have a material class, so I'm leaving now. Goodbye Professor Lu!"

After Liu Lang finished speaking, he picked up his schoolbag and left.

"What? Liu Lang's physics knowledge plenary session? Professor Lu, are you saying that if Liu Lang participates in the youth competition, he will get first place?"

Zhao Tianming was shocked when he heard Professor Lu Hua's report.

"I can't guarantee that I will get the first place, but what I can guarantee is that as long as the test questions fall within the scope of high school knowledge, Liu Lang will have no problem.

Of course, the test papers we are getting now are from the Soviet Union and Eastern European countries, and our country's curriculum is borrowed from them. The teaching content for the same age group on both sides is similar, but this competition is in the United States, and we do not know their teaching content.

,so………!"

Lu Hua is a physicist, and everything he does and says must be proven by facts. He will not easily make assertions without factual support.

"He has no problem with knowledge within the scope of high school! So he can participate in youth-level competitions?"

Zhao Tianming asked.

"Haha, this needs to be decided by the leaders, but in my opinion you can give it a try. After all, high school level content is not challenging for Liu Lang!"

Lu Hua said with a smile.

"Okay, Professor Lu, your suggestion is very good. I will ask the Education Committee for instructions!"

Zhao Tianming picked up the phone and dialed Lu Mingzhi's number.

"What? The questions in the youth group are not difficult for Liu Lang at all...? Okay, okay, I'll ask the leader for instructions right away!"

Lu Mingzhi couldn't make the decision, so he immediately asked the larger leaders for instructions.

Zhao Tianming and Lu Hua waited for more than an hour before Lu Mingzhi finally responded.

Liu Lang still has to participate in the youth group competition, but this time it is not just a physics competition, but a competition in all three categories of mathematics, physics, and chemistry, and he must ensure that he gets good results in all three.

"What?"

Lu Hua was dumbfounded when he heard this.

"Oh, there is no way. Lao Lu just explained to me that the leaders were very happy to hear the news. They felt that Liu Lang would have the best chance of winning the championship only by participating in the youth competition!"

Zhao Tianming said helplessly.

"If that's the case, why do you need to add mathematics and chemistry? Are these completely different subjects?"

Lu Hua asked loudly.

"The leaders have said that if Liu Lang is good at physics in high school, he must be good at mathematics and chemistry. Anyway, mathematics, physics and chemistry are inseparable. If he is asked to participate together, he might win prizes in all three!"

Zhao Tianming answered.

"This...this...is really nonsense!"

Lu Hua wanted to refute, but he really couldn't.

"Forget it, forget it, I can't control this anymore, I'm leaving!"

Lu Hua slapped his butt and was about to leave.

"Lao Lu, don't go! You are the cause of this incident. You have to be responsible for telling Liu Lang!"

Zhao Tianming hurriedly stopped the other party. He knew that Liu Lang originally did not want to participate in this competition, but he finally agreed after putting forward several conditions. But now it is better, from the original physics single event to a math, physics and chemistry triathlon.

, if Liu Lang knew about it, he wouldn't "get mad" on the spot! He didn't want to get into trouble.

"Why! I'm just a physics teacher. I'm only responsible for teaching. I don't care about other things. If you want to go, you can go. If you don't go to someone else, no matter who goes, I won't go anyway! I'm leaving first. Goodbye!

"

Of course Lu Hua knew that this was causing trouble to Liu Lang, why would he say it?

Without waiting for Zhao Tianming to step forward, Lu Hua rushed out of the office in a few steps. He was so fast that it was impossible to tell that he was already in his sixties.

"You...you guy, really!"

Zhao Tianming shook his head. He didn't want to go either! But there was no way. He had to tell Liu Lang what the leaders had decided. As for whether the other party agreed or not, he didn't have the say. If Liu Lang

If you "fall out", then report it truthfully and let's talk about it when the time comes!

"Oh? Let me participate in three competitions in mathematics, physics and chemistry? Which level?"

Zhao Tianming went to Liu Lang's home in person, but Liu Lang didn't have any dissatisfaction, which made Zhao Tianming feel relieved.

"Liu Lang, you still have to participate in the youth level. The leaders said that only in the youth level can you have a greater chance of winning the championship. As for the youth level, the country doesn't care much at all. After all, at this age, our country still has many talents.

If you haven’t really grown up, you still have a certain gap compared with the world’s outstanding scientists.”

Zhao Tianming is right. The country’s youth at this stage are basically students who have just graduated from university. Most of them are young people in their twenties. How can they show themselves on the world stage if their studies are not solid yet? Three

Not to mention the age group of teenagers. Because they were engaged in sports, they basically didn’t go to school. It would be embarrassing to let them participate in the world competition. Therefore, the country almost gave up on the youth group and only sent

A few graduate students in their thirties went to show off.

The focus is still on the youth group. I originally thought that Liu Lang was not a major and his relevant knowledge was not solid, but now I have discovered that he is an all-rounder in mathematics, physics and chemistry, and he is still the youngest. In the world, I am afraid that there are no more people around his age.

No, if he can win an award, even a bronze medal, it will bring great face to the country. In this regard, the country is not wrong and is very wise.

Of course Liu Lang understood that because he was not a major, he thought those Olympic competition questions were so difficult that he would not get a good ranking and waste time. However, Lu Hua took out the questions from the previous youth group.

I found that the youth group is really not that difficult, as is physics, and the same goes for math and chemistry. I have to go to the United States anyway, and participating in one project is the same as participating in two or three.

"Grandpa Zhao, don't worry. It's my duty to win glory for the country. Three are three. It doesn't matter. But I can't delay my own courses, and I have a lot of things to do recently. I need to discuss cooperation with the third factory. Anyway, mathematics and

Chemistry is not difficult for me either. As for this training, I will take part in it when I have time."

"You little guy, you are even busier at work than an old man like me! But you are busy with serious things, and I am just busy. Okay, I agree to your request, but I also have to tell the leaders about your request.

Whether they agree or not, I can’t make the decision.”

"Grandpa Zhao, just say that if you don't meet my demands, I will go on strike and not attend. I believe they will agree!"

Liu Lang said bluntly.

"Haha, you little guy's words are really tough. Alas, I was very tough when I was young, but now that I'm old, it's useless, it's useless...!"

Zhao Tianming looked at Liu Lang and was filled with emotion. He seemed to remember himself when he was young. At that time, the country was in war, and he was also a passionate man who never flinched in the face of the enemy's bayonet. But now, he doesn't even ask for a single request from his students.

I can guarantee that...

Of course, he didn't take Liu Lang's words of "strike" seriously, and no one would take him seriously. At best, they just thought that he was trying to act like a child.

"Okay, I'm leaving, you can go about your business!"

Zhao Tianming saw a stack of paper in front of Liu Lang, with dense words written on it, and the title was "How to Manage a Factory". It was obvious that Liu Lang was writing something, so he didn't say much to the other party.

"Grandpa Zhao, I will support you!"

"No, no, although I am old, my health is still good. I will retire next year, and then I will be finer and have more time to write some history... History is good! Okay.

Let us learn from history and avoid detours. History is great!"

Zhao Tianming gradually walked away "nagging", and Liu Lang couldn't calm down for a long time looking at his thin back.

Great intellectuals such as Zhao Tianming have lived in cowsheds and been criticized. They have suffered so much that they cannot imagine, but their loyalty to the country remains unchanged. This is called faith, because they always firmly believe that their country will become stronger.

This little bit of suffering is nothing in the face of national honor and interests. This firm belief is still far behind me!

I hope these people can live a long life and see the moment when the country rises.

Liu Lang couldn't help but pray for these people.
