It's been a long time since I've seen you. It's inevitable that you'll meet again in another foreign country.

While eating and chatting, this meal inadvertently went from 12: 00 to over 2: 00.

After checking out the bill, the three men walked to the door.

When he said goodbye, Ark looked at Chen Yushan and said sincerely: “I'm so sorry this time... I'll take my driver's license and come to Philadelphia to buy you dinner. ”

As soon as Chen Yushan's eyes lit up, he said: "Well, I'll remember this meal! ”

Looks like you're still a little upset about hanging yourself at the airport for half a day.

The boat patted its chest and said, "Don't worry, I promise I won't let you pigeon! ”

In a farewell fashion, Chen Yushan returned to the University of Pennsylvania, while the ark boarded Brother Ross' car and went to Princeton, a small town between Philadelphia and New York.

Sitting in the car, the ark fastened its seat belt and asked casually.

“What's the deal over there? ”

Brother Luo said as he drove: "Which aspect did you ask? ”

The ship thought about it and said, "Like, dormitories? ”

Brother Luo: “Dormitory? It's good and bad, but you certainly don't have to worry, math and physics are at the top of the Princeton discipline stigma chain, and you're enrolled as a Kim Dae and Utah joint training program, and there will probably be a single room for you. But to be honest... I personally find it interesting to have four people in two bedrooms. ”

Ark: “Won't it bother you? ”

Brother Luo smiled and said, “Actually, it's fine. It's interesting to make friends with people from different countries. The most important thing is that the dormitories are not cool. And in addition to the liveliness, there is a large living room for four people and a party on the weekends. Me and my ex-girlfriend met at a weekend party for an international student. ”

Funny?

Forget it.

The Ark laughed.

If he had a choice, he would prefer a quieter place.

Along the way, Brother Ross talked to him about Princeton's campus, but the topic somehow drifted to his previous girlfriend.

With an embarrassing and rude smile on his face, the ark listened quietly to him.

Just as he was about to fall asleep, Brother Luo finally stopped telling his emotional history and parked the car on the side of the road.

“Here we are.”

The sleeping ark looked out the window and saw familiar buildings.

unconsciously arrived at the destination.

After getting out of the car, Brother Luo helped the Ark pull the suitcase out of the back of the car and said casually.

“I'll take you through the formalities. I don't think you've had time to go to Princeton last time. The first time I come here, I may get lost, and every year I meet a freshman who asks directions. ”

The ark nodded and said, "Thank you, then. ”

Indeed, the last time he came to Princeton, he spent most of his time in a ten-square hotel studying twin speculation. And when he turned that assumption into a theorem, the five-day academic conference was over and he soon boarded a return flight.

Brother Luo grinned: “Trouble is, everyone is one of us, we should help each other outside. ”

As he spoke, he took the ark and went in the direction of the administrative building.

……

As one of several American colonial universities, Princeton University is influenced by both academic style and campus architectural layout, with an Oxford-inspired archetype.

This old board is like two tiger bronze statues in front of Nassau Hall, insisting on themselves in a changing world.

While most of the elites who graduate from here will meet at some investment bank on Wall Street, it has to be said that this is indeed the furthest from the famous resort in Ivy League.

Brother Luo did not accompany the ship in front of Nassau Hall, but stood outside waiting for him and looked at the suitcase for him.

Walk into this historic administrative building with your own materials and the boat quickly finds a place to register for school by following the instructions in the booklet and the door deck on the side of the corridor.

Sitting in the office is a Latin American woman in her 30s, slightly darker, with ponytail braids, probably an assistant or something from the looks of her outfit.

Perhaps someone came here to say hello in advance and told the lady that a Chinese student would come to report today, so she just looked at the ark and said formally.

“Do you have the materials? ”

“It's all here.” The ark delivered the material in its hand.

After checking the material to make sure there was no problem, the lady opened the drawer at hand.

“Your student registration is on file, here's your student ID and the key to the dorm, with the door number tag on it, be sure to keep it safe. In addition, your dorm is in this location...” He said, drawing a circle on the map of the freshman manual with a ballpoint pen. The lady returned the freshman manual to the hands of the ark and smiled, “Have a good life learning. ”

That's it?

The ark blinked and looked at her.

Noting the inquiry in her gaze, she asked, “Is there anything else? ”

The Ark looked at the only key and student ID in his hand and asked, "Where's my mentor? ”

“It depends on your choice,” the lady looked at the ark and continued, "Normally people identify their doctoral mentors before enrolling in school, but your situation is a bit special. My suggestion is that if the opportunity is rare, you can look for a few classes to listen to and then choose the right mentor to start your studies… provided they have time, of course, and preferably as soon as possible. ”

I mean, do you want to interview yourself?

The Ark thought he had been booked by the school.

But that's fine.

It would be troublesome to arrange a mentor at random and eventually find that it doesn't fit.

As soon as he came out of the administrative building, Brother Luo walked towards him.

“Procedures are in place? ”

“Kind of. ”

“Who is your mentor? ”

“I haven't thought about it yet...”

“Not yet?” Brother Luo looked at him surprised and said unexpectedly, "I thought you had thought about this at New Year's. ”

The ark coughed softly and said: "There was a lot going on in the New Year's Eve, I wasn't busy... can you give me a recommendation? ”

Brother Ross thought about it and said, "If you recommend it... if you're going to jump into the big pit of mathematical physics, of course I'm going to be the first to push my boss, Edward Witten. Delinière is a good choice if you're planning to take on algebraic theory or algebraic geometry. If you had been here a few years earlier, you could have even started with Andrew Wiles, the Proof of Fermat's Theorem, but, unfortunately, he started teaching at his alma mater Oxford in 11 years. And Faltines, the prover of Modell's speculation, is also because of the bulls in algebraic geometry and mathematics...”

In addition to his ex-girlfriend, there seems to be something in this brother's stomach.

Though I haven't worked with him, it's impossible not to have the slightest skill to study for a PhD under Edward Witten.

After listening to his suggestion, the ark thought seriously for a moment and nodded: “I'll think about it. ”

Brother Luo smiled and said, "Do you want me to take you to the dorm? ”

Ark: “No, look at the map. I think I can find a place. Send me here. ”

“OK, call me if you need anything. ”

“Well, definitely! ”

After being separated from Brother Luo, the ark followed the route on the map and went in the direction of the dormitory building.

His dormitory is located in the clear corner of Princeton campus, not far from the Institute of Advanced Studies.

With a great sense of direction, the ark easily found this place.

Although he had seen the photograph of the dormitory building in the freshman's manual, he was more or less prepared. But when he saw the dormitory in reality, he was surprised.

It's...

Too vintage!

It is said that this colonial-style British building is more than ninety years old and can be applied to a museum. Despite several successive renovations, the building remained largely intact.

Especially the dark red brick wall, and the inky green vines on the wall, look like an ancient mansion in its vintage.

By the way, isn't there really a ghost in here?

With such doubt, the ark walked in.

As he walked up to the second floor with his suitcase, he looked up and saw a figure suddenly standing on the stairs.

Because of the poor light on the stairs and the fact that she had just come in from a bright spot, the ark could not see her face clearly, but judged her to be probably a lady by her figure and the outline of her skirt.

The person with long hair between his ears and arms smiled at him.

“You're finally here. ”

Ark was shocked to see the man talking to himself and still being familiar with his mouth.

Grass!

Is this a ghost?
