Two o'clock in the afternoon that day.

It is still the auditorium of the old campus of Jinling University.

Although the audience was one-fifth less than yesterday, the atmosphere was still quite hot.

Responding to the audience's gaze, Lu Zhou, who was standing on the stage, explained the details of the steps while writing on the blackboard.

As one blackboard filled, the staff quickly dragged another one and lined up the one on the table.

In this way, the staff went to the stage five times, and the blackboard was filled with six.

When Lu Zhou wrote the last line, that is, the last explanation, the audience stood up excitedly.

Thunderous applause spread from the front row to the back row like a tide, and instantly filled the entire report meeting.

Looking at the blackboards on the stage, Edward Witten, who was applauding, smiled and said, "Fortunately, I didn't go back early, or I really missed this historic moment." ”

A smile also stretched on Deligne's face, and he said with a little emotion.

"Maybe his talent in other areas of mathematics is indeed much stronger than in algebraic geometry."

Hearing this, Feverman joked, "Don't be discouraged, maybe he just hasn't developed an interest in algebraic geometry for the time being." When he became interested, perhaps the entire algebraic geometry community would be amazed by his results. ”

Deligne smiled noncommittally.

"I wish there was such a day."

The undulating applause gradually subsided.

It comes and goes like a tide.

As the audience sat down again, Lu Zhou stopped the chalk in his hand.

Looking back at the audience, Lu Zhou cleared his throat and spoke slowly.

"With regard to the Jan Mills equation, we have got its general solution. As for the interaction between microscopic particles, as well as the form of their existence or motion, we will also get a deeper understanding from a mathematical point of view. ”

"In the next step, I will try to explain the mass gap problem of strong interactions from a mathematical point of view."

Listening to the sound of surprise coming from the audience, Lu Zhou paused for a moment and continued to speak.

"Here's the Q&A."

……

The solution of a proposition is not the same as the proof of a proposition.

The latter requires rigorous proof of thought, and there is no room for the slightest error.

In the case of the former, even if no process is provided, or even just a guess of the outcome, it is allowed by the academic community.

Just as Hua Lin proposed that "every positive integer can be represented as the sum of up to r to k-power, where r depends on k", and boldly predicted that g(2)=4, g(3)=9, and g(4)=19.

He did not provide a clear idea of how to solve these conclusions, and the proof of the existence of g(k), as well as the subsequent numerical solutions, were solved by later generations in the next century and a half.

In fact, if Lu Zhou didn't give a perfect solution idea, it didn't matter.

At most, it will leave a suspense for future generations, so that in the next half century or a century, they will seek a mathematical aesthetic solution process, and test whether this conjecture is correct through mathematical methods rather than computers......

In short, with the end of the Q&A session, the report meeting also came to a successful conclusion, and the scholars who visited China also boarded the return plane one after another.

Ten o'clock in the evening, Jinling International Airport.

Edward Witten, who was sitting in the waiting room waiting for his flight, had just picked up a magazine and was about to sit down to read it, when he was immediately stopped by a reporter.

"Professor Witten, what do you think of this presentation?"

"It was a very good presentation, and I would like to thank Professor Lu for bringing this presentation to us, and I would like to thank Jinling University for their hospitality, and I still miss that ...... Jinling roast duck? It seems to say so in Chinese. Sandwiched between a series of English in half-baked Mandarin, Witten joked with the reporter with a pleasant face.

Regardless of whether there was a laugh or not, the reporter also smiled, and then continued to ask: "Then how do you evaluate the content of this report?" ”

After hearing this question, Witten thought for a moment before speaking.

"There is no doubt that this is a landmark achievement for both the history of mathematics and the history of physics. We have found the general solution of the Yang Mills equation, which means that we can understand the secrets of the microscopic particle world more deeply from a mathematical point of view, and reveal the physical phenomena that we have not yet discovered but still exist. ”

"From the perspective of a theoretical physicist and a mathematical physicist, I think this will be the most outstanding research achievement of the year."

Reporter: "Even if this year has just begun?" ”

"Yes, I'm sure of that." Glancing at his watch and seeing that the time was almost up, Witten looked at the reporter and continued, "If you have any questions, it's best to be a little faster, and I'll be ready to board in five minutes at most." ”

If the situation is optimistic, he will still be able to make it to the CERN meeting.

However, compared to the gains of his trip to China, what he was able to get from Switzerland was already dispensable.

"I promise, this is the last question," the reporter quickly flipped through the shorthand notebook, selected the most topical question, and asked, "Some people criticized Professor Lu and said that it was a great offense to the scholars present to leave the venue abruptly during the presentation, as an internationally renowned scholar, how do you feel about this matter?" ”

"Internationally renowned scholars can't talk about it," Witten smiled and teased a little modestly, "at least I still lack a Nobel Prize compared to Professor Lu." ”

After the joke, he paused for a moment and continued.

Generally speaking, no one would choose to leave the scene unless there was a reason for it, after all, it was a matter of whether his argument would be accepted by the rest of the academic community. But if there's something that has to be done, at least I personally think it's understandable. ”

Reporter: "So you think this accusation is unjustified?" ”

"Well, at least after seeing such a brilliant result, I have no more thoughts than to be satisfied," Witten smiled and continued in a light-hearted tone, "If you were to ask my opinion, I think that to criticize a scholar who has made an outstanding contribution to the edifice of theoretical physics for such inexplicable reasons, and to superficially think that we are as superficial as he is, and not to be joking......"

"I think that's the biggest offense to us."
