Go back to the past and be a schoolboy

"When the enemy is about to take away our country's defense force, when there is a serious crisis in the country, our relatives will be naked, our children will become hungry, and our homes will be taken away by others. ?"

At the meeting of the Prussian Academy of Sciences, Cheng Nuo quietly entered through the back door and found a corner where no one was paying attention and sat down quietly.

It was better to come early than coincidentally, just in time for Planck to give a speech at the Congress of the Prussian Academy of Sciences.

"Everyone, my dear German colleagues, it is about the hope of our German scientific community, and it is even more about the future of our motherland. Can you agree?"

"No!" Everyone in the audience replied in unison.

"Very good." Planck nodded in satisfaction, and pressed his hands down: "I believe that when a more serious crisis may be yet to come, there is at least one thing here that no external or internal enemy can get out of our hands." What was taken away was the place of German science in the world..."

In sharp contrast to the enthusiastic atmosphere on the scene, there was a young scholar with thinning hair in front of Cheng Nuo, who was muttering non-stop and shaking his head from time to time, obviously disagreeing with the above.

Being idle, Cheng Nuo couldn't help but poked his head forward and said curiously: "Sir, it seems that you don't quite agree with Professor Planck's point of view, do you have a better opinion here, can you share some two?"

The young scholar looked around, made sure that there was no one else beside him, and after he was sitting in that row, he hesitated and said, "Are you talking about me?"

Cheng Nuo nodded: "Yes, I'm talking about you, sir. To be honest, I am also opposed to blindly killing chicken blood. But it is related to the future of the German scientific community. I also want to hear other people's opinions and see if I can learn from it." What did you learn in middle school?"

The young scholar smiled kindly, twisted his neck back and said, "Actually, I think it's because Professor Planck didn't recognize the reality. We Germany will definitely be defeated. The best way at this time is to stop militaristic research and ease the situation." Relationships with international colleagues."

After a pause, the young scholar said softly: "Just like Professor Haber, he voluntarily proposed to the Ministry of War to undertake the task of solving the problem of raw material supply, researching chemical weapons and throwing them directly into the battlefield, but now I heard that he has stepped down as the director of the research institute, Abandoning the villa assigned to him, he has long since run away without a trace."

Cheng Nuo's pupils tightened: "You mean, Professor Haber may have slipped away?"

The young scholar smiled and said: "Need to say, the news of our German army's defeat on the battlefield has already spread to all the alleys in Berlin. In the past six months, the German army has killed, wounded and captured more than 85 people. , the distance from the defeat is very close.

Once the battle is defeated, Professor Haber, as the person in charge of chemical warfare, must be liquidated. If he doesn't run away now, when will he wait?On the day of the real defeat, I couldn't run away even if I wanted to. "

Cheng Nuo was secretly happy. It seemed that the trap he had set for Ha Bo before was not in vain, so he waited to do his best to make him unable to stay in a neutral country, so he had to go to China with Cheng Nuo.

The so-called Wei San Que Yi, "three" refers to each neutral country, "one" refers to China.

But right now this is not the point. Looking at this young scholar, Cheng Nuo somehow felt a little familiar.

Although I'm sure I haven't seen a picture of this person who looks exactly like this person in my mind, but it looks familiar, and I didn't ask directly, but continued to think of ways to formulate words.

"Sir, it seems that you know Mr. Planck very well?"

"Both teachers and friends, the relationship is not bad." The young man thought for a moment, and gave his answer: "At least compared to you and me, I must have a lot of acquaintances, and some things can be outspoken."

Cheng Nuo was a little embarrassed when he heard this, and scratched his head in embarrassment.

But just as he was scratching his head, Cheng Nuo suddenly discovered that the young scholar had a white rose on his chest. Matching the other person's temperament, he looked chic and coquettish, really handsome.

Unable to bear curiosity, Cheng Nuo asked, "Sir, is your white rose purely for decoration?"

The young scholar smiled mysteriously: "Of course not, this flower is not an ornament, but a gift for a friend."

Cheng Nuo pressed, "Is it a female friend?"

The young scholar shook his head and said with a smile, "No, it's a male friend."

Cheng Nuo became even more curious. The reasons for sending flowers, white roses, and white roses to male friends were really unpredictable.

It's a pity that this young man's mouth is too strict. No matter what Cheng Nuo asks later, the other party just refuses to reveal a word, which directly makes Cheng Nuo's heart itch.

But to Cheng Nuo's surprise, although the other party looks very young, he has high academic attainments. When it comes to some mathematical problems, young scholars can not only handle some math problems, but also give Cheng Nuo a lot of attention by virtue of his unconstrained thinking. inspiration.

Mathematics and physics don't separate families, and in the end, the topic turned to physics for some reason, and now it's a relatively unfamiliar field for Cheng Nuo, and the discussion of problems is not as easy and comfortable as before.

Fortunately, Cheng Nuo's brain was good enough. After the young scholar slowed down a little, the topic became lively again.

Looking at the other person's hairstyle, which was faintly developing towards the direction of the explosion, a name suddenly appeared in Cheng Nuo's mind, and his strong curiosity prompted him to ask the other person's identity again: "May I ask if you are Professor Albert Einstein?" ?”

"Oh? You know me? If there isn't another guy named Albert Einstein around here, then you're talking about me. I thought you only knew Professor Planck?" Love Einstein graciously admitted his identity, and he didn't forget to make fun of Cheng Nuo.

Now Cheng Nuo was really embarrassed. To blame, he could only blame the fact that there was no photo of Einstein in the history textbook, and he had to hang a naughty photo with his tongue sticking out. The memory left by Cheng Nuo was too deep, so After seeing the young Einstein, it took a long time to recognize the real person.

Fortunately, Einstein was also a generous person, so he didn't take this matter to heart. Instead, he became curious about Cheng Nuo's identity: "Based on your understanding of mathematics and physics just now, your academic level is also very high. If you think about it, you must not be an ordinary person, I don't know your name?"

Cheng Nuoxin said that you finally asked my name, otherwise I wouldn't know how to introduce myself later.

After organizing the language a little, Cheng Nuo smiled and said, "My name is Cheng Nuo, I'm from China, and I'm a math lover."

Einstein suddenly realized: "I know you, your mathematics research is very famous, I also read your papers at that time, which helped me a lot in my research in physics, I didn't expect you to be so young, it is unbelievable. "

He had always admired Cheng Nuo's talent, but after learning about Cheng Nuo's identity as a mathematician, Einstein liked Cheng Nuo very much, and then threw all the mathematical problems he had accumulated to Cheng Nuo, Let it help answer.

The previous questions were fine, but later on, with the deepening of Einstein's understanding of mathematics, the questions raised became more and more tricky, and involved many sub-disciplines.

Even for Cheng Nuo to answer, it took a lot of effort.

Seeing more and more questions coming up, Cheng Nuo couldn't take it anymore, so he quickly found a topic to divert the other party's attention, and glanced at the white rose on Einstein's chest again, curiously said: "Professor, what's the matter?" Can you tell me why you are carrying a white rose?"

Unexpectedly, Einstein still shook his head: "Temporarily keep it secret, you will find out later."

At this moment, Planck got down from the podium without knowing when, not only did not sit back in the first row, but also went straight to Cheng Nuo.

After seeing Cheng Nuo, he took the initiative to reach out his hand: "You are Professor Cheng Nuo, right? Nice to meet you."

Cheng Nuo was a little surprised. He didn't expect the other party to recognize him directly. One must know that he had never been to Europe before. How could the people here know what he looked like? It was really puzzling.

However, what Planck said next dispelled Cheng Nuo's doubts: "I saw you in the newspaper. When you published your paper, you and your academic achievements were published in the journal of our Academy of Sciences. Thinking of seeing the real person, I will look younger than the photos."

Cheng Nuo hurriedly stepped forward to shake hands: "Where is it? I just made some simple results at the beginning. I didn't expect to make such a deep impression on you, professor. I feel a little ashamed."

Einstein on the other side coughed, took the initiative to separate the two, and gave Planck an affectionate and powerful hug.

Nothing was said, and everything seemed to be said.

After a long time, Einstein broke free suddenly, took off the white rose on his chest, and handed it to Planck.

"This flower was actually given to Planck by Einstein?!"

But after thinking about the relationship between the two, Cheng Nuo exclaimed, but also felt that it was reasonable.

From 1912, Planck was one of two permanent secretaries of the Mathematical Physics Division of the Prussian Academy of Sciences, the most influential post in German science, and later succeeded him as rector of the University of Berlin.

Given Einstein's enormous influence, the Prussian Academy of Sciences at the time expressed a strong interest in him.

Under Planck's efforts, he successfully passed the proposal of co-opting Einstein as an academician with a huge advantage of 21:1 voting.

Planck and Nernst immediately went south to Zurich and tried their best to persuade Einstein to take a post in Berlin as a member of the Prussian Academy of Sciences, a professor at the University of Berlin, and the director of the soon-to-be-established Kaiser Wilhelm Institute for Physics.

They agreed to meet at the train station at noon the next day. If Einstein agreed to go to Berlin, he would hold a red rose, and if he disagreed, he would hold a white rose.The next day, Einstein appeared with a red rose in his hand, and the two became important partners.

However, now that Einstein was holding the rose again, it just changed from red to white, which made Cheng Nuo curious.

When Planck next to him saw the rose, his face was obviously taken aback, and then he said bitterly: "Are you really going to do this?"

Einstein was a little helpless: "I don't want to go all the way to the dark with those radicals. It is not wise to resist in the corner. The future of the motherland should not be the only way you said, whether it is for the people or for us scholars. , peace is the most important thing."

Plank also wants to struggle: "But now you are contrary to the mainstream thinking in the country to fight to the end, which will have an unnecessary negative impact on your reputation."

Einstein shrugged: "You know me, I don't care."

Looking at the white rose in his hand, Plank couldn't be happy anyway, but he couldn't persuade his friend, so he had to wave his hand in the end.

"As you please."

Although the two were at a stalemate for the time being, Cheng Nuo's opportunity to express himself had arrived. After the exchanges between the few people, and after they became relatively familiar with each other, Cheng Nuo took the initiative to speak for Planck:
"One of the vital necessities of the nation is the protection of the few great assets it still possesses. German science stands out among them.

Science is not only the most important prerequisite for maintaining national education, technology and industry, but also the most important prerequisite for national reputation and world status. "

Plank nodded, and turned curiously: "So what are you trying to say?"

Cheng Nuo smiled and said, "I want to establish a good cooperative relationship with the Prussian Academy of Sciences."

World War I is seen as the first modern industrial war, in which basic and applied research played a greater role than ever before, contributing to the militarization of the nascent modern science.

Scientists engage in war for a variety of reasons, such as patriotism, nationalism, or naive political goals, such as dedicating one's talents to the military cause of one's home country or using them to escape the front lines, such as obtaining additional research funding to perpetuate personal Or the scientific research projects and goals of the institute, etc.

Since the military was initially not interested in these scientists engaged in basic research, the societies and scientists, under various motivations, took some initiatives in the name of fulfilling their patriotic obligations. These actions were put into practice, resulting in direct What the consequences reflect is the transition from basic research to applied research.

In particular, new discoveries in basic research are not only applied to military technologies such as wartime communications, weapon sound insulation, ballistics, and ammunition, but also to medical treatment and industrial production.

It is the winter of life, but it is also the warm spring of practical science.

But everything has two sides, there are advantages and disadvantages.

Bringing the knowledge of civilian scientists to war has changed the conduct of warfare, but at the same time prolongs it and makes it more brutal.

Just like the inventor of the Gatling machine gun, Richard Jordan Gatling. As a doctor, his original intention of inventing this gun was actually to reduce casualties, but he did not expect that more soldiers were injured or died. .

To add insult to injury, before World War I, the mark and the dollar were the currencies that maintained the gold standard, and the exchange rate was 1 marks to one dollar.

However, in 1918, when Cheng Nuo lived, the exchange rate dropped to 1 marks to 8.9 US dollar during the few years when inflation was still growing slowly.

In other words, the mark is worthless and the German economy is about to collapse.

However, the results of wartime research will be difficult to continue to apply to Germany's post-war economic recovery.

What Cheng Nuo wanted was to exchange as much profit as possible from the German scientific community with the least benefit to help the domestic industry develop.

Commonly known as taking advantage of the fire!
"This world war was an incubator in which virtually every technology, strategy, and ideology was developed in the arsenal of political actors."

Looking at the two of them, Cheng Nuo said slowly, "Placing these things in other places can also reflect their value, that is, I am willing to contribute a little bit to everyone.

Red roses, white roses, are good roses. "
