Chapter 664: I read, you write

?
At the same time, the other end of Eurasia, located in the lecture hall No. 1 of CERN headquarters in Switzerland, is a crowded scene.
Wearing a formal dress, Luo Wenxuan stood on the aisle next to the podium, carefully checking the manuscript in his hand, and constantly breathing deeply in order to adjust his beating heart.
Although it is not the first time to stand in this place, the feeling of standing on and off the stage is completely different.
This is the temple of the international physics community.
In half an hour, he will be tested by the top scholars in the world of physics.
As Luo Wenxuan was nervously preparing for the final preparations, a familiar voice suddenly came from the side.
"Your tie is too tight. This will affect your ventilation."
Upon hearing this voice, Luo Wenxuan immediately looked back, a surprised expression appeared on his face.
"professor?"
"Not to be surprised, you should know that I was at CERN for at least six months of the year," said, Witten smiled, and joked with a funny tone, "Not to mention And there is such an important report waiting for me. "
Luo Wenxuan smiled embarrassedly, reached out and scratched his head.
"Thank you for messing up."
"Professor Lu chooses to entrust this report to you, which shows that he believes you can do it. If I were you, there is no need to be so nervous, just as an ordinary report meeting."
Nonsense ... you are a Filipino award winner, you certainly don't need to be nervous, but the problem is that I have never won the Fields Award.
Luo Wenxuan didn't speak, and he uttered in his heart speechlessly.
Seeing that he was silent, Witten paused for a moment and continued, "Speaking of it, is Professor Lu good?"
Luo Wenxuan: "Very good in all senses, but research is still as busy as ever."
"Really? It's his style," Witten smiled. "Actually, I don't think he needs to be so anxious. He has already reached a height that many people can't reach in a lifetime, in just a few years. And he There are still decades in the future to continue studying ... My suggestion is that he can consider changing to a healthier lifestyle and taking time out to study or something while studying. "
Luo Wenxuan: "I will convey your suggestions to him."
"It's not a suggestion, it's just my own perception of past life," said Luo Wenxuan, who was still nervous, and Witten smiled. "And you, take it easy. If I remember correctly, you should Not the first time here. "
Luo Wenxuan said nervously, "But I was always offstage before."
Wittenhaha smiled and said, "Are you going to stand on the stage soon? I'm bullish on you, don't let me down."
Then, he patted the shoulders of former students, turned around and walked away.
...
After chatting with a former mentor, Luo Wenxuan felt a lot more relaxed.
Soon, it was time to start the report.
After walking to the stage to stand, Luo Wenxuan took out his mobile phone from his pocket and placed it next to the microphone on the multimedia desk while dialing the Internet phone.
Facing the quiet venue, he cleared his throat and said.
"For various reasons, Professor Lu was unable to come to the scene in person, so I was appointed to conduct the briefing on his behalf. If you have any questions about this, you can raise it before the briefing."
When the voice fell, someone raised their hand.
Luo Wenxuan made a polite gesture and said politely.
"The professor, please."
Standing up tremblingly from the seat, I saw an old man with a hawk nose and a gully face, staring sharply at Luo Wenxuan, who was standing on the stage, full of weight. Said slowly.
"There is only one question I want to ask. What role did you play in the research on the Young Mills equation?"
Luo Wenxuan looked at other listeners and it seemed that many people were concerned about this issue.
Adjusting his breath, he said in a voice as smooth as possible.
"I ... mainly provided a possible proof of thought and discussed with him on the method of solving the problem. Of course, as described at the end of the paper, the main argument was done by him alone."
The old man continued to ask, "Can I think that your point of view represents his point of view?"
Did n’t you just say one question?
Speaking in his heart, Luo Wenxuan continued.
"Of course you can ... unless Professor Lu expresses a clear objection," he said, pointing to the mobile phone on the multimedia desk, and continued, "he will be watching online all the way through the report, if I have something that is not mature enough He will add ... if he interrupts my speech, everything will prevail. "
The old man nodded and sat back.
Luo Wenxuan was relieved.
"Then, please turn the paper in your hand to the abstract part. Let's start from the beginning ..."
Although it is impossible to be nervous, he still quickly entered the state after the report began.
In fact, he was not without his experience of making reports in CERN. Even under the cultivation of Witten, he had a lot of opportunities to report on the stage, but those reports were not particularly important. Not so much.
Time passes by every minute.
An hour had passed in an instant.
Finally, watching PPT turned to the last page, Luo Wenxuan was finally relieved, but there was no feeling of lightness in his heart.
Although the PPT was finished, the report meeting did not end.
The next questioning session is the key to the whole report!
"The details of this paper are basically these ... if you have any questions, you can raise them."
When he announced that he had entered a questioning session, his hands were raised immediately.
Luo Wenxuan glanced at the old man who raised his hand. Seeing that he was still the previous one, he nodded to him.
"please say."
Standing tremblingly from the chair, the old man with a hooked nose asked with a steady voice.
"Page 9, line 23 of the paper, for a more general polynomial-type interaction on R? Such as λR (φ) + φ? How do you know sexual and isolated single-particle spectra? "
After listening to this question, Luo Wenxuan was relieved.
The difficulty is quite satisfactory, and it is not a particularly difficult problem.
After clearing his throat, he went to the whiteboard and picked up the marker while answering the blackboard.
"For the two-dimensional R (φ) with a small coupling constant, the presence or absence of a bound state depends on the specific situation of R (φ). A field theory with a bound state will have a mass operator M, whose spectrum Mass gap (0, m) and upper gap (m, mb) ... so we can tell that its existence is known. "
"As for the single particle spectrum ..."
Just after half of what he said, the marker in Luo Wenxuan's hand stopped suddenly, and his voice stuck there.
It was as if a ball of cotton had blocked his throat and he couldn't make a sound.
Isolated single particle spectrum ...
MMP!
How to answer this?
A drop of cold sweat gradually slipped from his forehead.
The speed of the brain's operation has reached its limit ~ EbookFREE.me ~ he called almost all the brain cells to think about this problem.
However, it was just in vain.
Whispering voices gradually spread in the venue. From the eyes of several professors sitting in the front row, Luo Wenxuan saw a hint of disappointment.
After a difficult swallowing, he gradually felt cold in his hands and feet.
What should I do……
He couldn't imagine what would happen if he messed up.
Even though Lu Zhou might forgive him less, he could not forgive himself.
But at this moment, a sound like nature sounded from the cell phone resting on the multimedia desk. Although there were only four words, he was full of power for an instant.
Just listening to Lu Zhou on the other side of the phone, she said in an understatement but with a very reliable voice.
"I read, you write."
