Pang Xuelin stayed in the capital for more than ten days to apply for a visa to the United States.

15 March 1993.

Capital International Airport.

Pang Xuelin, accompanied by Xie Yongxin, president of the Chinese Mathematical Society, Geng Huan, deputy director of the Information Department of the Ministry of Foreign Affairs, and others, boarded a plane to the other side of the ocean.

Ah Qing naturally accompanied him.

Pang Xuelin and his entourage got on the plane at 3:30 p.m. on March 15, and it was not until 17 p.m. EST that they arrived at Newark International Airport near New York, which was later known as Newark Liberty International Airport.

United Airlines Flight 93, which crashed in Pennsylvania in 2001, departed from the airport during the 911 incident and was renamed Newark Liberty International Airport to commemorate the incident.

After completing the entry procedures, Pang Xuelin and his entourage just came out of the international passenger channel, and were greeted by nearly 100 reporters carrying long guns and short cannons and flashing lights.

During this time, Fermat's conjecture, Pang Xuelin, 20 years old, high school graduate, primary school teacher, these keywords have almost swept the screen in the Western media, and have also aroused great interest among the Western public.

A 20-year-old mysterious genius boy from China who solves a mathematical problem that has plagued mankind for three hundred years.

No matter from any angle, no matter what country people are, this news is very topical.

The media was noisy for more than half a month, and after learning that Pang Xuelin had boarded the plane to the United States to hold a report meeting, almost all of the world's top media sent teams to interview.

Pang Xuelin naturally became the focus of everyone's attention.

"It's Xuelin Pang, they're out......"

As soon as he came out of the exit of international passengers, Pang Xuelin was recognized by reporters.

Soon, dozens of reporters surrounded everyone, and the microphone in their hands was about to poke Pang Xuelin's face.

"Pang, there are rumors that the paper was ghostwritten, and you are just a puppet launched by the Chinese government, is that so?"

"Pong, a professor of mathematics at New York University, Robbins Cook, claims that your proof of Fermat's conjecture is fundamentally flawed, what do you think of his assertion of this?"

"Pang, may I ask how you are just an ordinary high school graduate, how did you master those difficult mathematical knowledge?"

……

Fortunately, the embassy pick-up staff was nearby, and had already contacted the airport security, Geng Huan stepped forward to communicate with the other party, and the group walked to the parking area of the airport without saying a word under the protection of the security guards.

The reporters did not let Pang Xuelin go at all, chasing everyone to take pictures, and kept asking questions.

Ah Qing timidly followed Pang Xuelin's side.

In the past half a month since he came out of Lingziding Village, Pang Xuelin is refreshing Aqing's worldview step by step.

Especially after boarding the plane to the United States, those blonde and blue-eyed foreigners made Ah Qing even more timid.

Pang Xuelin pulled Ah Qing to the other side of him, avoiding the cameras of reporters.

Maybe he was walking too fast, maybe he was accidentally pushed, and as soon as he walked out twenty or thirty meters, Ah Qing fell to the ground with a thud.

"Ah Qing, it's okay!"

Pang Xuelin was startled, and quickly stopped and helped Ah Qing up.

"Teacher Pang, I'm fine!"

Taking advantage of this pause, the crowd was surrounded by reporters again.

"Teacher Pang, it's okay, why don't I carry A-Qing on my back?"

Geng Huan walked up to Pang Xuelin and said in a low voice.

Before coming to the United States, Geng Huan had already described to Pang Xuelin the attitude of the Western media and made a coping strategy.

In other words, no interviews will be given before the official presentation is held.

But now, Pang Xuelin found that if he continued to remain silent, he might not even be able to get out of the airport.

"Geng Si, you take care of A-Qing, I'll come out and say a few words."

As he spoke, Pang Xuelin stood up directly and said loudly in English: "Be quiet, please keep quiet!" Listen to me. ”

Soon, the noisy scene instantly quieted down, and all reporters pointed the microphone at Pang Xuelin.

Pang Xuelin said: "This is a public area, in order not to interfere with the normal operation of the airport, I can only make a brief response. ”

"First, I will not be interviewed by any media until the end of the briefing."

"Second, for all my personal doubts, I believe that after the Fermat conjecture report, everyone will get a clear answer!"

"Third, after the report meeting, I will accept formal interviews with three media outlets, and you can submit an interview application to the Chinese Embassy in the United States, and I will select suitable platforms for speaking out as appropriate. If you continue to block here, then I'm sorry, I won't be interviewed by any of the media who are blocking the road at the scene! ”

Maybe Pang Xuelin was too imposing, or maybe Pang Xuelin's threat played a role.

In short, after saying this, the reporters at the scene were quiet for a while, and they silently gave way for Pang Xuelin and his party to pass.

In the evening, Pang Xuelin attended a welcome dinner hosted by the Chinese Consulate General in New York.

After staying at the Consulate General for one night, Pang Xuelin took the convoy arranged by the embassy to Princeton early the next morning.

The Institute for Advanced Study in Princeton has arranged a five-star hotel for Pang Xuelin, which is near the Institute for Advanced Study in Princeton.

By the time the convoy arrived, Deligne had been waiting for a long time with many of the leaders at the Institute for Advanced Study in Princeton.

Pang Xuelin got out of the car and saw Pierre Deligne, who was standing at the front of the crowd at the front of the crowd, much younger.

"Hello, Professor Deligne, I'm Pang Xuelin!"

Pang Xuelin stepped forward and shook hands with Deligne in fluent English.

"Pong, welcome to Princeton!"

Deligne was a little surprised by Pang Xuelin's English level, but he quickly reacted and said with a smile: "Come, let me introduce you, this is my colleague Andrew Wiles!" ”

"Hello, Professor Wiles!"

Pang Xuelin shook hands with Andrew Wiles with a strange expression.

It was this big guy who really turned Fermat's conjecture into Fermat's grand theorem in history.

However, Pang Xuelin is not much embarrassed to rob this big man's achievements, after all, compared with the proof method of Ponzi geometry, Andrew Wiles's method of proving Fermat's conjecture is too complicated, and in terms of mathematical significance, it is far from comparable with Ponzi geometry.

"Hello, Pang!"

Andrew Wiles looked at Pang Xuelin with a complicated expression, shook hands with Pang Xuelin, and said.

Deligne continued, "This is Professor Edward Witten! ”

"Hello, Professor Witten!"

Pang Xuelin looked at the middle-aged man with a rectangular face and a slightly raised chin in front of him, and couldn't help but be slightly surprised.

This big man is a figure who can be a god in the physics community in later generations, and is almost recognized as the first person among theoretical physicists and the one with the highest H index among contemporary physicists.

Needless to say, his achievements in physics are also extremely influential in the world of mathematics.

The fact that he is the only physicist to have won a Fields Medal speaks volumes about his weight.

In the field of pure mathematics, he used Jones polynomials to explain the Chen-Simmons theory", which had a profound impact on low-dimensional topologies and derived quantum invariants.

Although in this era, Theory M, which had a profound impact on the entire theoretical physics, had not yet been put forward by Witten, it did not affect the status of this big man in the academic world.

"Pang, welcome to Princeton, I can't wait to hear your presentation!"

Edward Witten said with a smile.
