After more than 20 hours of long-distance flight, Qin Ke arrived at Philadelphia International Airport in New Jersey.

Also accompanying this trip were two teachers from Qingmu University, Sun Liwen, Zheng Haiqiao, and Chen Ming.

Sun Liwen and Zheng Haiqiao are both middle-aged men in their thirties and strong. According to reports, Sun Liwen, a lecturer in the Department of Mathematics and Mathematics, served as a guide this time because he had an undergraduate degree at Princeton University and is good at taking photos.

He is also responsible for recording Qin Ke’s movements at the report meeting, taking photos, writing promotional materials and other matters; while the other Zheng Haiqiao is an employee of the Academic Affairs Office and is responsible for arranging Qin Ke’s life affairs together with Chen Ming.

Fortunately, Sun Liwen looked familiar to Qin Ke, but Zheng Haiqiao had never been seen in school. However, Zheng Haiqiao was personally arranged by Vice Principal Gu to accompany him on the trip. This arrangement must have been the intention of the school.

Zheng Haiqiao looked serious and didn't like to talk much, similar to Chen Ming, but Sun Liwen was very talkative and had a great time chatting with Qin Ke along the way.

After leaving the airport, a car was already waiting for them. Qin Ke and the four of them got in the car. The journey was smooth and they arrived in Princeton in the afternoon.

The wheels rolled over the remaining unmelted snow. Qin Ke faced the bright sunshine and curiously looked at this famous small cultural town.

Yes, although Princeton is called a "city", it is actually the size of a rural town. The economy is not prosperous, with only about 30,000 residents. It is even worse than Qin Ke's hometown, Qingping Town. Even buses and

There are only a handful of taxis, and it is almost impossible to travel without a private car.

However, its scenery is quite beautiful, and passers-by have tranquil and leisurely expressions on their faces. There are many scenes of people sitting outside with books and drinking coffee while basking in the sun. It has a strong cultural atmosphere.

Because the Christmas holiday has just ended, you can still see Christmas trees, ribbons, and slogans celebrating Christmas in the town, which is quite Western.

The city of Princeton is most famous for its Princeton University and the Institute for Advanced Study located here.

Princeton University is extremely famous in the world of academic circles and is the legendary temple of mathematics.

It has always adhered to the principle of academic supremacy and is world-renowned for its tradition of focusing on quality, research, and theory. Even in modern times, it still "stubbornly" does not offer the most popular majors such as MBA, medicine, and law, but only focuses on mathematics and philosophy.

, physics, history, economics, architecture and other traditional subjects.

It is this focus and persistence that makes Princeton University famous in the world and has cultivated countless elite talents, including two U.S. presidents, 12 Supreme Court justices, 69 Nobel Prize winners, 15

Fields Medal winners, 14 Turing Award winners, and countless other outstanding graduates.

The Institute for Advanced Study (IAS) in Princeton is also a world-famous theoretical research institution and academic mecca. It has the same origin as Princeton University but is not affiliated with each other. It consists of the School of Historical Studies, the School of Mathematics, the School of Natural Sciences and the School of Social Sciences.

, physicist Einstein, mathematics master von Neumann, logician Kurt Gödel, game theory master John Nash, etc. have all conducted research here.

Qin Ke looked through the local information in his hand and suddenly remembered that Qingmu University also had an Institute for Advanced Study, which was said to be modeled after the Institute for Advanced Study in Princeton.

The car quickly arrived at its destination. According to the arrangements of Qingmu University, Qin Ke did not stay at the "Princeton Hotel" designated by Princeton University for this academic seminar, but stayed at the Peacock Hotel next door. Sun Liwen, who was traveling with him, Zheng Haiqiao and Chen Ming lived in the rooms on his left and right.

After settling down and washing away the dust, Qin Ke put on a casual and light down jacket, and accompanied by Sun Liwen and Chen Ming, went to visit Princeton University and "check out" the conference venue in advance.

Qingmu University has not had a student get an offer from Princeton University for several years, whether it is a master's degree offer or a doctoral offer, so at this time, there is no current alumni to serve as guides, and lecturers like Sun Liwen can only follow from China. Being a guide is a bit embarrassing.

There are students from Yanda University who come to study for master's degree at Princeton, but why does Qingmu University have the nerve to ask for students from its competitors?

There is no way around it. Princeton University has always adopted the principle of "preferring to be admitted without success". It requires excellent academic performance, a high level of oral English in the written test, and academic achievements such as competitions or publishing papers, and winning awards. For Xia Guo students, , in the first condition, spoken English is already the first obstacle, and the subsequent academic achievement requirements are even more difficult.

There are too few people who can win gold medals in world-class competitions or publish papers in international academic journals at the high school or undergraduate level.

Therefore, Princeton does not recruit more than one student from Xia Guo every year. Sometimes it cannot recruit suitable students for two or three consecutive years, so it frees up the spots for Europe.

Under such strict requirements, it is not surprising that Qingmu University has not been admitted to Princeton University for master's or doctoral degrees in the past six years. However, Yanda is very famous for its mathematics major, and occasionally one or two super talented scholars will obtain Princeton University's master's degree. Master's degree offer.

"Look, the small iron gate in front is the gate of Princeton. It's called Fitzrandolph Gate. There used to be a rumor spread from nowhere in China that Princeton University students can only enter and exit this gate once in their lifetime, when they are enrolling and graduating. There is no such thing as saying that you can’t graduate if you leave midway. Anyway, I often went in and out here when I was an undergraduate. Didn’t I also get an undergraduate diploma and a bachelor’s degree certificate? Of course, occasionally I will reflect on it, can’t I pass the exam? As a graduate student at Princeton University, is it because I keep coming in and out of the gate?"

Sun Liwen laughed first when he talked about the latter part. Qin Ke couldn't help but admire it and secretly praised him. Teacher Sun was very eloquent and a very qualified guide.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Sun Liwen is said to be the IMO gold medal winner fifteen years ago. His English level is also very good. He scored a TOEFL score of 115 in high school. I was lucky enough to be admitted to Princeton University and became an undergraduate majoring in mathematics. However, I failed when I was admitted to the graduate school of Princeton University. Later, I worked hard to get a combined master's and doctoral program at the University of California, Berkeley. I returned to Xia Guo two years ago and currently He is a lecturer in the Department of Mathematics at Qingmu University.

“From the school gate, you can see the most important building of Princeton University, the administrative building, Nasu Building, which has the motto of Princeton University on it.”

"The motto of Princeton University is ' ', and the English version is 'rishes', which means 'She prospers in the name of God.' This is because Princeton University was originally founded by the Dawn Presbyterian Church, a Christian church, and has traces of the church.

"

"Look, there are two bronze tiger statues in front of the Nasu Building. They are the mascots of Princeton University. I will take you to visit the Art Museum and the Flintstone Library..."

Qin Ke followed Sun Liwen as he walked through this world-famous university. He had to sigh that this was indeed an ancient and solemn university full of humanistic atmosphere. Gothic dome buildings and ancient Greek buildings can be seen everywhere, and there are also many

Some modern and simple sculptures and decorations add a bit of vitality to this ancient school.

College students from all over the world passed by the three of them from time to time. They just glanced at them curiously, then withdrew their gaze and continued to talk. This kind of confident and proud look, even at Yanda University in China,

It is rare to see students from top universities like Qingmu.

It can be seen that the students in Pudong University are very proud of being members of Pudong University.

Qin Ke took a lot of photos casually and planned to send them to Ning Qingyun to share after returning to the hotel with WiFi.

Princeton's number theory special academic lecture will be officially held tomorrow, and will be held in the auditorium of Princeton University. A welcoming banner has been put up at the entrance of the auditorium building, and staff are coming in and out to make final arrangements for the venue.

Finishing work.

Qin Ke and others completed their "stepping on the spot" and saw that it was already getting late. They were about to turn back along the school road, but after only walking for a moment, they unexpectedly heard a "quarrel" coming from a corner not far away.

To be precise, it is an academic dispute.

Qin Ke looked over in surprise and saw a bonfire lit in an open space a dozen steps away. Ten foreign students were surrounding the bonfire to launch an "attack" on one of the students, who was obviously Asian.

"Xu, you just proposed in class that by setting the adjoint surface of '-2', the double integral can remain finite on the four-dimensional surface. I don't agree with this view at all. According to Griffiths' algebraic geometry principles

, your setting completely fails to explain how curves on a surface eliminate singular points."

"That is, did you ignore the genus formula of the curve on the surface?"

"When Enriques surfaces are all quotients of K3 surfaces, the '-2' you set is useless, and the irregularity of S'' is not taken into account at all..."

A blond-haired American student even wrote directly on the whiteboard next to him: "Look, using my calculation method, your assumption is completely unnecessary."

Graduate student Xia Guo, surnamed Xu, was speechless when asked, and then blushed amidst the laughter of other students.

Qin Ke asked Sun Liwen next to him in a low voice: "Is this the academic exchange atmosphere at the University?"

Sun Liwen rubbed his nose and said with some embarrassment: "That's right. There are quite a lot of outdoor debates in PKU. When eating and drinking beer around a campfire like this, they often re-discuss some of the points in the class that day. PKU's

Students are encouraged to speak actively in class. Basically, professors ask questions, and students take turns to answer them below. Whether they are correct or not is also left to the students for collective discussion. The professor only provides inspiring guidance and summary. This is how the General University uses this kind of thinking collision.

To stimulate students' creative thinking and improve students' thinking agility. However..."

When Sun Liwen said this, he seemed to remember his own embarrassing experience, and sighed: "Students from Xia State have a harder time in the general assembly, because their test scores are very good, but their immediate answers in class are often not outstanding.

…”

Qin Ke understood. To put it simply, he was good at doing the paper slowly, but not so good at making sudden changes on the spot.

It’s no wonder that under the domestic education system and the non-native English language environment, it is no longer easy to fully understand the professor’s courses, let alone quickly keep up with the rhythm, think about the answers and express them clearly orally.

Out.

Qin Ke shook his head. They were having an academic exchange. Although the atmosphere was a bit unpleasant, he didn't want to get involved. He was about to turn around and leave when he heard a foreign student say: "Xu, can you come to our University?"

, he should be regarded as the most powerful person in mathematics among the students of Xia State, right?"
