Far from the other side of the Atlantic, Germany, a class of crystal chemistry at the University of Munich.

Professor Gerhard Etter rarely did not teach his teaching assignments to his own teaching assistants, but personally stood in the classroom to explain the mysteries of crystal chemistry for these young students.

For a Nobel Prize-winning scholar, this kind of teaching and educating work seems to be somewhat sloppy. However, in fact, many well-known scholars are happy to share their knowledge with young students.

The same is true of Professor Ethel, especially when he is in trouble for a complex problem.

Engaging in basic education can always inspire him at a critical moment.

In the final questioning session of the class, suddenly a student raised his hand and asked.

“Professor, have you seen the paper on the theoretical model of electrochemical structure interface recently published in “jacs”?”

Professor Etter stopped for about two seconds, pushed the reading glasses and nodded.

"Look, is there any problem?"

The student looked at him with a look of expectation and asked, "Is it right?"

Etell thought for a moment and said in a chattering voice: "My child, out of rigorous science, I can't answer you for this question."

However, the student did not seem to be satisfied with this vague answer. He changed the question and broke the casserole and continued to say: "If it is correct?"

"There is no science, but you have to ask this question..."

Professor Etter frowned and seemed reluctant to comment on the topic, but in the end he stretched his eyebrows and said with a relaxed tone, "If it is right, it means new chemistry."

There was an incredible horror in the classroom.

New chemistry!

What a shocking statement!

If someone else says this, the people present may not be taken seriously at all. But this sentence is Professor Ettel, Nobel Prize winner in 2007, an expert in the field of solid surface chemistry!

In addition to his role as a professor at the University of Munich, he is the director of the Fritz Haber Institute (Institute of Physical Chemistry and Electrochemistry) at the Max Planck Institute in Germany.

In the field of electrochemistry, who else has more say than him?

Looking at the students' reactions, Professor Ethel smiled.

"I am very happy to see that you are optimistic about the birth of a new theory. You are right. Only by constantly accepting new things can we make progress."

“But while being curious about new things, I hope that you will always remember to look at every conclusion we make with a rigorous attitude.”

"This is responsible for science."

Having said that, Ettel tapped the desk with a lesson.

"I will send the assistant to your email address, now, class."

After leaving the classroom, Professor Etter did not return directly to his office, but took his own car and rushed to the Fritz Haber Institute of the Max Planck Institute in Berlin.

The recent papers published in "jacs" have caused widespread controversy in the chemical industry. As one of the world's top academic research institutions, Mapu has the obligation to express its position on this paper.

Of course, this statement is not just a casual way to stand up and stand up.

Considering the importance of this theoretical model for the study of electrochemical interface structures, the Max Planck Society has set up an interdisciplinary team to bring together top scholars in the fields of mathematics, chemistry, and condensed matter physics to discuss this theoretical model.

As a member of the research group and the director of the Institute of Physical Chemistry, Ettel's opinion also represents the opinion of the Institute of Physical Chemistry of the Max Planck Institute.

It is precisely because of this that he is particularly cautious when dealing with this topic.

Walking into the conference room, he saw Faltins sitting there, holding a paper printed in a paper document, and examining it meticulously.

Strictly speaking, this amnesty is an expert in the field of algebraic geometry and arithmetic geometry. Functional analysis is not his research direction. However, as a big cow in the field of number theory, cross-directional research is not a rare thing for him.

At the same time, as one of the most influential mathematicians after Grothendieck, and the director of the Max Planck Institute for Mathematics,

Otherwise, he will not be the director of the Max Planck Institute for Mathematics.

However, this arrogant Germanic old man was this temper when he was at Princeton. After returning to his hometown in Germany, he did not change anything. Instead, he became more and more serious.

As if to deliberately say to Ettel, Faltins said slowly.

"Only second-rate mathematicians are interested in how to apply mathematics to solve real-world problems. In my opinion, such things have no value at all."

Indifference to application is the consistent position of the Bourbaki School, and “glorious isolation” of other disciplines is often regarded as a noble one. Although it is difficult to feel the scorn chain in this discipline among young mathematicians, this stubborn concept still exists in the older generation of mathematicians.

The outstanding representative is probably the late master of the number theory Hardy. In addition to the research, the cow's favorite thing is to show off to others. He studies the purest and purest mathematics. His own research has no mathematics. Beyond the "use" and take pride in it.

However, it is "unfortunate" that Hardy never dreamed that his research results were eventually taken away by the "狡猾" application scientists and widely used in computer and cryptography...

Of course, Faltings said that Lu Zhou is a second-rate mathematician, but he regrets his squandering talent.

At last year's Crawford Awards ceremony, he said that only four-digit scientists in the world today are expected to surpass him, and in his opinion, Lu Zhou is the most promising.

However, now he is hesitant, or do not want to change these four into three.

Sitting opposite Faltins, Ettlel picked up his eyebrows: "I don't dare to share your point of view."

"I didn't expect you to agree. Just as not everyone can appreciate the sculptures of ancient Greece, you can't count on a laity, you can understand the beauty of pure mathematics." Faltins said faintly.

Ettel’s eyebrows twitched.

Seeing that the two had to quarrel again, Professor Klaus von Klein coughed a lightly, and the tone was quite helpless to play round the road.

"Enough, Mr. Faltins, we hope that you will provide more constructive suggestions, not to listen to you ridiculing us."

Professor Klaus von Klein is a member of the Max Planck Institute for Condensed Matter Physics. Although he is not a director, he is the discoverer of the quantum Hall effect and a nominee.

"I didn't ridicule you," Sharp's gaze glanced at the paper, and Faltins turned a page, resolutely and stubbornly correcting, "I'm just explaining the facts."

Ethel and Klein exchanged their sights and decided not to communicate with the stubborn old man until he finished reading the last part of the paper.

Fortunately, Faltins did not intend to continue to open his mouth and carefully read the papers in his hands.

After a long time, he threw the paper on the table and gave a rating that was barely acceptable.

"From a mathematical point of view, his process is not a big problem."

Ethel and Klein were relieved.

If Professor Faltins feels that there is no problem, then basically it should be no problem in the sense of mathematics.

Klein looked at Etter and asked: "What do you think about this theory?"

After a few moments, Ettels said, "In my opinion, the problem is not very big. But his theory is too obscure. Even if we give an approval, we can't let the chemical industry accept his point of view. ""

Klee’s heart moved a little: “What do you mean?”

Etel nodded. "Nothing is more appropriate than a report. The more difficult the theory is, the more it needs to communicate directly with me."

The index finger was gently lit at the conference table, and Klein thought and asked, "What do you think is appropriate?"

"We can, send an invitation letter to Princeton, invite Professor Lu to come to Mapp to visit and exchange, and provide him with a platform to explain his views to the entire theoretical chemistry community."

Have to say that this is a good idea.

Klee Qing nodded in recognition.

"I agree with you, but the question is, which institute is sending an invitation?"

This is a very critical issue.

The Max Planck Society is not a top-down centralized research institution, and the institutes are basically independent of each other.

However, this is also a problem that does not need to be considered at all.

The two almost said in unison.

"Of course it is our Institute of Physical Chemistry."

"Of course it is our mathematics institute."

Because the sound was too consistent, even after the words, Faltins and Ettel both squatted together.

Frowning slightly, Fartings said in an emphasized tone: "He is a mathematician."

Ettel looked at him incredulously and argued with reason: "But we are talking about chemistry now."

Seeing that the two men were not arguing, Klee Qing coughed and made a compromise.

"Since you can't make up your mind, don't you just be at the Institute of Condensed Matter Physics..."

"impossible."

"Don't think about it!"

In the face of the two screams, Klee whispered softly: "I just said it casually... If this is the case, decide it in a traditional and ancient way."

The tradition of physicists.

Naturally, I bet.

"Front elimination, the reverse continues," took a coin from his pocket and took it on the table. Professor Klein paused and said with a little excitement. "Of course, for the sake of fairness, I will also participate."
